Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The water purification equipment comprises at least two filter elements, wherein the conventional filter elements are usually four to five stages, and the multi-stage filter elements are integrated into one filter element (a composite filter element) which is a preferred scheme.

In addition, in the process of assembling the large composite filter element for the water purifier, various problems that the filter element is large in size, and when the filter element is fixed on a thin water circuit board, displacement vibration is easy to occur, noise is possibly generated, or a connector of the water circuit board is damaged are often encountered.

In order to solve the technical problems of the composite filter element, the invention provides a middle frame structure of water purifying equipment.

A middle frame 20 for a water purifying apparatus 1000 according to an embodiment of the present invention will be described with reference to fig. 1 to 11.

As shown in fig. 1-3, 32-33, the middle frame includes a connecting base shell and at least two hollow support posts. Two or more hollow support columns are connected together through a connecting base shell, and the hollow support columns extend along the vertical direction to form columnar filter element cavities which are arranged side by side.

The middle frame 20 is positioned in the housing 10, the outer contour of the connection base housing 21 matches the inner contour of the housing 10, and the connection base housing 21 has a plurality of bypass holes 2111 penetrating the top and bottom surfaces thereof. A hollow support column 22 is formed at the bottom of the connection base housing 21 corresponding to the escape hole 2111, and the hollow support column 22 extends from one side (e.g., the upper side of the middle housing 20 in fig. 2) to the other side (e.g., the lower side of the middle housing 20 in fig. 2).

It can be understood that, due to the matching of the connecting base shell 21 and the shape structure of the outer shell 10, the inner wall surface of the outer shell 10 and the outer wall surface of the middle shell 20 are better fitted and lean against each other to form the shell structure of the shell assembly 100.

The hollow support column 22 divides the cavity into a plurality of independent installation positioning spaces, for example, a filter element, a water pump or an adapter can be arranged in the hollow support column 22. For example, a filter cartridge can be placed into the hollow support post 22 from the bypass aperture 2111.

The inventor has conducted several tests on the middle frame 20 and found that the overall structural strength of the middle frame 20 is related to the diameter of the filter element cavity and the height of the middle frame 20, and the diameter of the filter element cavity must be smaller than the height of the middle frame 20. Wherein, the diameter of the filter element cavity is D, and the height of the middle frame 20 is H. The inventor further found that when the D/H is set to 0 to 1/2, the middle frame 20 is hardly deformed or damaged, and when the composite filter element is loaded in the filter element cavity and the filter element is fixed on a thin water passage plate, the composite filter element is not easy to displace, and hardly generates sound during working or carrying, and the problem of poor accommodating performance of the middle frame to the filter element caused by the size of the multi-stage filter element and the large difference of the filter element adapter can be avoided.

In addition, the inventor also finds that the ratio of the shortest distance between two adjacent filter element cavities to the diameter of the filter element cavity and the structural strength of the middle frame 20 have a large relationship, wherein the shortest distance is L, the diameter of the smallest filter element cavity is D1, and L is more than 1/6D1, so that the middle frame hardly has the problems of deformation and damage in drop and impact resistance tests, and can effectively protect the filter element in the filter element cavity and avoid the displacement or damage of a water channel plate.

Therefore, according to the middle frame 20 for the water purifying device provided by the embodiment of the invention, the space requirement of integrating the multi-stage filter elements into the composite filter element is met by reasonably designing the diameter of the filter element cavity and the height of the middle frame, a waterway system is optimized, and the problems of displacement of the filter element, damage of a waterway plate and the like are avoided.

As a preferred embodiment of the present invention, the middle frame 20 may be formed by an injection molding process, in which a mold is divided into an upper mold having a first left mold, a loose core block and a first right mold, and a lower mold having a second left mold and a second right mold, the upper mold and the lower mold are pressed and injection molded into the mold, and after a certain period of time elapses, the loose core block is first drawn out after the middle frame 20 is formed, and then the first left mold and the first right mold are separated, and the second left mold and the second right mold are separated.

And secondly, the mold is divided into a left mold, a middle mold and a right mold, the loose core loose piece is formed on the middle mold, when the left mold and the right mold are tightly pressed, the loose core loose piece is positioned in a cavity formed by the left mold and the right mold, then the loose core loose piece is injected into the mold, after the middle frame 21 is molded, the loose core loose piece is firstly drawn out, and then the left mold and the right mold are separated.

The technical problem that the loose core block needs to be pulled out after the injection molding of the middle frame 20 is finished, when the upper die or the middle die moves upwards, the loose core block also moves upwards from the hollow supporting column 22 along with the movement of the upper die or the middle die, and because the friction force between the inner surface of the hollow supporting column 22 and the loose core block is large, the hollow supporting column 22 is easily pulled out from the lower die, and even the hollow supporting column 22 is pulled off and cracked.

In addition, since the longitudinal length (up-down direction in fig. 2) of the hollow support column 22 is long, it is not convenient for a worker to remove the hollow support column 22 from the lower mold. For this reason, the inventors have made intensive studies to improve the structure of the center frame 20. An interference portion is provided on the outer surface of the hollow support column 22, and the interference portion is concave or convex with respect to the outer surface of the hollow support column.

Specifically, as shown in fig. 2 and 3, the middle frame 20 includes: connecting a base shell 21 and a plurality of hollow support posts 22. The hollow support column 22 is connected to the bottom of the connecting base shell 21 and extends downwards along the vertical direction, the connecting base shell 21 is provided with an avoiding hole 2111 penetrating through the upper surface and the lower surface of the connecting base shell, the hollow support column 22 is communicated with the avoiding hole 2111, the outer surface of the hollow support column 22 is provided with an interference portion 221, and when a mold is pulled out, the interference portion 221 is matched with a lower mold to prevent the hollow support column 22 from moving synchronously along with the loose core block and the upper mold.

In other words, the middle frame 20 includes a connection base shell 21 extending in the left-right direction in fig. 2 and 3 and hollow support columns 22 extending in the up-down direction, and a plurality of hollow support columns 22 are each formed on the connection base shell 21. I.e., a plurality of hollow support posts 22 are located on the same side (lower side in fig. 2 and 3) of the connection base housing 21.

This application is through setting up interference portion 221 at hollow support column 22's surface, during the loose piece drawing die, the loose piece of loosing core has drive hollow support column 22 ascending effort F1, interference portion 221 and lower mould cooperation exert decurrent effort F2 to hollow support column 22, wherein F2 and F1's opposite direction, thereby avoid hollow support column 22 to be taken out the lower mould, therefore, can prevent that hollow support column 22 from following the loose piece motion of loosing core, and then avoid hollow support column 22 to be pulled apart or pulled apart, and receive the influence of interference portion 221, hollow support column 22 takes off from the lower mould more easily.

The number of the hollow supporting columns 22 is not particularly limited, and for example, the number of the hollow supporting columns 22 may be two, three, or more, and specifically, as shown in fig. 2 and 3, the hollow supporting columns 22 are two arranged side by side and at intervals in the left-right direction, wherein one hollow supporting column 22 is connected to the left side of the connection base shell 21, and the other hollow supporting column is connected to the right side of the connection base shell 21. The structural stability of the middle frame 20 can be improved by distributing the hollow support columns 22 at intervals on the left and right sides of the connection base housing 21.

Due to the high integration level of the composite filter element, the length and the diameter of the filter element are relatively large, such as a preferred embodiment, the height range H of the middle frame is set between 250MM and 600MM, and preferably, the height range H of the middle frame is set between 350MM and 500 MM; the diameter D of the filter element cavity arranged in the middle frame is set to be 80MM-120 MM; preferably, the ratio of D/H is less than 1/2.

The height of the middle frame 20 is understood to be the height of the middle frame 20 that covers the upper and lower ends of the filter element, and it is understood that the upper and lower ends of the middle frame 20 may have a portion of the margin for mounting or fixing the housing or other components connected to the filter element, such as a water channel plate.

Through a large number of tests, the inventor obtains the numerical relationship among the diameter of the filter element, the diameter of the filter element cavity, the height of the filter element, the height of the middle frame, the shortest distance L between two adjacent filter element cavities and the running noise, and the numerical relationship is shown in the following table:

according to the internal guide standard, the qualified standard of the drop test is as follows: after the test is finished, the product should not be damaged or damaged, the carton box should not be damaged or broken, the foam should be broken, the product should work normally and cannot be damaged, the shell and other attached products of the product should not be damaged or damaged, and the product should pass the conventional electrical property check to be qualified after the drop test.

The applicant has found, through numerous drop tests, that when the diameter D of the filter element cavity and the height H of the middle frame satisfy the relationship that D/H is less than 1/2, and the shortest distance between two adjacent edges of the filter element cavity and the diameter D1 of the smallest filter element cavity in the hollow supporting column 22: l is more than D1/6, the failure rate of drop test is less than D/H and more than or equal to 1/2, and L is less than or equal to D1/6.

Of course, the above embodiment is only illustrative, and should not be construed as limiting the scope of the present invention, for example, there may be one hollow supporting column 22, and the hollow supporting column 22 is connected to the middle portion of the connecting base shell 21, and there may also be three hollow supporting columns 22, and three hollow supporting columns 22 are arranged side by side and spaced left and right or in a triangular shape.

Therefore, according to the middle frame 20 for the water purifying device 1000 in the embodiment of the invention, the interference part 221 is arranged on the outer surface of the hollow support pillar 22, so that the middle frame 20 is less prone to breaking or fracture in an injection molding process, and the yield of the middle frame 20 is improved.

In an alternative embodiment, as shown in fig. 3 in combination with fig. 4, as shown in fig. 5 in combination with fig. 6, and as shown in fig. 7 in combination with fig. 8, the interference portion 221 is concave or convex relative to the outer surface of the hollow support post 22. Here, "concave" means that the interference portion 221 is recessed toward the center of the hollow supporting column 22, in other words, the outer surface of the hollow supporting column 22 is at least partially formed into a concave surface, so that the thickness of the tube wall at the interference portion 221 is smaller, as shown in fig. 5 and fig. 6. "concave-outward" means that the interference portion 221 protrudes outward away from the center direction of the hollow support post 22, in other words, the outer surface of the hollow support post 22 is at least partially formed convex, so that the wall thickness of the hollow support post 22 at the interference portion 221 is large. That is to say, the outer surface of the hollow support column 22 is not a flat surface, and the friction resistance between the outer surface of the hollow support column 22 and the lower mold is changed through the concave or convex interference part 221, so as to change the stress condition of the hollow support column 22 during core pulling, thereby preventing the hollow support column 22 from being pulled apart or broken.

It should be noted that the above embodiment is only illustrative, and the interference portion 221 may be a rough surface formed on the outer surface of the hollow supporting column 22, such as a frosted surface, so as to change the friction force between the hollow supporting column 22 and the lower mold, and further change the force condition of the hollow supporting column 22 during core pulling.

In a further alternative embodiment, the interference portion 221 has a V-shaped cross-section in the longitudinal direction (e.g., up-down direction in fig. 6 or 8). As shown in fig. 5 in conjunction with fig. 6, the interference portion 221 is formed as a V-shaped concave surface that opens toward the radially outer end, and as shown in fig. 7 in conjunction with fig. 8, the interference portion 221 is formed as a convex point that extends toward the radially outer end, and the outer contour of the convex point is V-shaped. It is to be understood that the cross-sectional shape of the interference portion 221 in the longitudinal direction is not limited to the above, and the cross-section of the interference portion 221 in the longitudinal direction may also be square, quadrangular, tapered, or the like.

In an alternative example, as shown in fig. 5 in conjunction with fig. 6, the interference portion 221 includes: the ascending section 2211 and the descending section 2212, and the ascending section 2211 and the descending section 2212 both extend towards one side of the central direction of the pipe body and intersect with each other. That is, the upper segment 2211 extends from top to bottom toward the center of the hollow support column 22, the lower segment 2212 extends from top to bottom away from the center of the hollow support column 22, and the upper segment 2211 and the lower segment 2212 extend in opposite directions. In other words, the upper row 2211 extends obliquely downward and inward, so that the wall thickness of the hollow support column 22 at the upper row 2211 is gradually reduced from top to bottom. The descending section 2212 extends obliquely downward and outward so that the wall thickness of the hollow support column 22 at the descending section 2212 gradually increases from top to bottom. That is, the wall thickness of the interference portion 221 of the hollow support post 22 is gradually decreased and gradually increased, so that the friction force between the hollow support post 22 and the lower mold is effectively increased.

Wherein the included angle between the upper segment 2211 and the lower segment 2212 is between 120 and 180 degrees. For example, the included angle is 120 °, 130 °, 140 °, 150 °, 160 °, 170 °, or 179 °. It is to be understood that the above is illustrative only and not limiting to embodiments of the invention, for example, the upper and lower segments 2211 and 2212 may be angled at 100 ° and 110 °.

In a further alternative example, as shown in fig. 4, the line connecting the outer end of the upper run 2211 to the outer end of the lower run 2212 coincides with the outer surface of the hollow support column 22. That is, in the top-to-bottom projection, the outer end of the upper segment 2211 coincides with the outer end of the lower segment 2212. The outer surfaces of the portion of the hollow support column 22 above the upper row 2211 and the portion of the hollow support column 22 below the lower row 2212 are in the same vertical plane, thereby increasing the overall structural strength of the hollow support column 22.

In one embodiment, as shown in FIG. 4, the distance h1 between the outer end of the upper run 2211 and the outer end of the lower run 2212 is between 4-10 millimeters. That is, the height of the V-shaped longitudinal cross-section of the interference portion 221 is between 4-10 millimeters when it is recessed relative to the outer surface of the hollow support post 22. For example, 4 mm, 5mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm. It can be understood that the friction between the lower mold and the hollow supporting column 22 is changed by adjusting the distance h1 between the outer end of the upper segment 2211 and the outer end of the lower segment 2212, so as to effectively prevent the hollow supporting column 22 from being pulled apart or cracked in the core pulling process.

In a further alternative example, the perpendicular distance d1 between the intersection of the upper and lower segments 2211 and 2212 and the connecting line is between 0.3 and 0.8 millimeters. Wherein the connecting line and the outer surface of the hollow supporting column 22 are located on the same vertical plane, that is, the perpendicular distance between the innermost end (the end closest to the center of the hollow supporting column 22) of the interference part 221 and the outer surface of the hollow supporting column 22 is between 0.3 and 0.8 mm. For example, d1 is 0.3 millimeters, 0.4 millimeters, 0.5 millimeters, 0.6 millimeters, 0.7 millimeters, and 0.8 millimeters.

In an alternative example, the angle of inclination of the upper row segment 2211 with respect to the vertical is greater than the angle of inclination of the lower row segment 2212 with respect to the vertical. That is, the slope formed by the ascending segment 2211 is steep, and the slope formed by the descending segment 2212 is gentle, i.e., the ascending segment 2211 extends in the vertical direction for a longer distance than the descending segment 2212 extends in the vertical direction. Interference portion 221 is so designed, and the lower die is more favorable to being taken off from hollow support column 22, and demolding efficiency is improved. Wherein, the included angle between the upper segment and the vertical direction is beta, and beta is between 110 DEG and 180 deg. For example, β is 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, and 179 °.

In an alternative example, the outer surfaces of the upper row 2211 and the hollow support column 22 and the outer surfaces of the lower row 2212 and the hollow support column 22 are smoothly transitioned. That is, the outer surface of the hollow support column 22 has no edges and corners, so that the worker is prevented from being punctured in the handling process, and the hollow support column is convenient to connect and match with other components.

In an alternative embodiment, as shown in fig. 7 and 8, the interference portion 221 includes: an upper segment 2211 and a lower segment 2212, and the upper segment 2211 and the lower segment 2212 both extend away from the center direction side of the hollow support column 22 and intersect. In other words, the interference portion 221 protrudes from the outer surface of the hollow support column 22, and the wall thickness of the hollow support column 22 at the interference portion 221 is larger. The included angle between the uplink segment 2211 and the downlink segment 2212 is 0-60 °, for example, the included angle is 10 °, 20 °, 30 °, 40 °, 50 ° or 60 °.

In a further alternative example, as shown in fig. 7 and 8, the outer contour of the interference portion 221 is a smooth curved surface. For example, the outer contour of the interference portion 221 is a smooth arc surface. Therefore, the outer surface of the hollow support column 22 can be smoother and more smooth, and hand cutting and injury can be prevented.

In an alternative embodiment, as shown in fig. 2 and 3, as shown in fig. 10 and 11, the interference portion 221 surrounds the outer circumferential surface of the hollow support post 22. The outer surface of the hollow supporting column 22 may include a plurality of interference portions 221, the plurality of interference portions 221 divide the hollow supporting column 22 into a plurality of sections of tubes, each interference portion 221 is located between two sections of tubes, wherein the outer surface of the interference portion 221 is convex or concave relative to the outer surface of the hollow supporting column 22, and the inner surface of the interference portion 221 and the inner surface of each tube are on the same vertical plane. Further, the number of the interference portions 221 is not limited, and for example, the number of the interference portions 221 may be one, two, three, or more than three, thereby dividing the hollow support column 22 into two-segment tubes, three-segment tubes, four-segment tubes, or more than four-segment tubes.

For example, the wall thickness of the hollow support column 22 is 0.5 millimeters, 1 millimeter, 1.5 millimeters, 2 millimeters, 2.5 millimeters, 2.6 millimeters, 2.7 millimeters, 2.8 millimeters, 2.9 millimeters, and 3 millimeters. It should be understood that the above description is intended to be illustrative, and not restrictive, of embodiments of the invention.

The water purifying apparatus 1000 according to the embodiment of the present invention includes the middle frame 20 for the water purifying apparatus 1000 of the above-mentioned embodiment, and since the middle frame 20 according to the embodiment of the present invention is not easily pulled apart or broken in the injection molding process, and is easily released from the mold, the water purifying apparatus 1000 according to the embodiment of the present invention has high production efficiency and low cost.

A water purifying apparatus 1000 according to some embodiments of the present invention will be described below with reference to fig. 1 to 17.

As shown in fig. 13 in combination with fig. 15, the housing 10 of the housing assembly 100 for the water purifying apparatus 1000 includes a first side wall 11, a second side wall 12, a third side wall 14 and a fourth side wall 15 connected end to end, the first side wall 11 and the second side wall 12 are symmetrically disposed with respect to a first direction (e.g., a front-back direction in fig. 15), the third side wall 14 and the fourth side wall 15 are symmetrically disposed with respect to a second direction (e.g., a left-right direction in fig. 15), each connection point of the first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 is connected in a smooth transition manner, and at least two opposite side walls of the first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 are arc-shaped walls.

For example, referring to fig. 15, the housing 10 has an oblong structure in a top view, the first side wall 11 and the second side wall 12 are located on the front and rear sides, and the third side wall 14 and the fourth side wall 15 are located on the left and right sides, wherein the first side wall 11 and the second side wall 12 may be arc-shaped walls, or the third side wall 14 and the fourth side wall 15 may be arc-shaped walls, or both the first side wall 11 and the second side wall 12, and the third side wall 14 and the fourth side wall 15 may be arc-shaped walls. That is, at least a part of the wall surface of the housing 10 is a curved surface, for example, a circular arc surface. Wherein the projection of the housing 10 in the horizontal plane may be oblong, e.g. elliptical.

Since the connecting portions of the first side wall 11, the second side wall 12, the third side wall 14, and the fourth side wall 15 are smoothly and transitionally connected, the outer wall surface and the inner wall surface of the casing 10 are smooth and smooth, and the structural strength of the casing 10 can be improved.

Of course, the housing 10 of the embodiment of the present invention is not limited to the oblong configuration described above, and the arc-shaped wall of the housing 10 is not limited to being convex outward away from the center of the housing 10 as illustrated in fig. 15, but may be convex inward toward the center of the housing 10.

Because two at least relative lateral walls of casing 10 are the arc wall for casing 10 anti deformability is stronger, has improved its structural strength, more can resist external colliding with, has improved casing 10's life.

According to the housing assembly 100 for the water purifying apparatus 1000 of the embodiment of the invention, by setting at least two opposite sidewalls of the housing 10 as arc-shaped walls, the horizontal distance of the housing 10 in the first direction and/or the second direction can be reduced by a proper amount, so that the housing 10 has stronger structural strength and occupies a small space, and various components of the water purifying apparatus 1000 can be compactly arranged in the housing 10, thereby improving the structural strength of the housing 10 and avoiding hollowing and breakage during transportation and carrying.

In an alternative embodiment, as shown in fig. 15, the first and second sidewalls 11 and 12 have a perimeter that is greater than the perimeter of the third and fourth sidewalls 14 and 15. In other words, the horizontal distance of the housing 10 in the first direction is smaller than the horizontal distance in the second direction, i.e., the extension distance of the housing 10 in the left-right direction in fig. 15 is larger than the extension distance in the front-rear direction.

In an alternative embodiment, as shown in fig. 13 in combination with fig. 16 and 17, the outer wall surfaces of the first side wall 11 and the second side wall 12 are flat, and the wall surfaces of the third side wall 14 and the fourth side wall 15 are convex outward away from the center of the housing 10. In other words, the third side wall 14 and the fourth side wall 15 are arc-shaped walls, the first side wall 11 and the second side wall 12 are flat surfaces, and the housing 10 is oblong in a plan view direction. That is, a part of the wall surface of the case 10 is a flat surface, and the other part is a curved surface. Wherein the third side wall 14 and the fourth side wall 15 are located at the left and right ends of the housing 10, and the second side wall 12 and the fourth side wall 15 are located at the front and rear sides of the middle portion of the housing 10. Because third lateral wall 14 and fourth lateral wall 15 are the arc wall, anti deformability is strong, and first lateral wall 11 and second lateral wall 12 are straight structure, and the structure is comparatively stable, can compensate each other between first lateral wall 11 and second lateral wall 12 and third lateral wall 14 and the fourth lateral wall 15 to improve the structural stability of casing 10 better, prevent that casing 10 from excessively deforming.

In an alternative embodiment, referring to FIG. 15, the central angle α of the third side wall 14 and the fourth side wall 15 is between 30-180. In this embodiment, the "central angle" refers to an angle of a circle where the cross sections of the third sidewall 14 and the fourth sidewall 15 correspond to, that is, the third sidewall 14 and the fourth sidewall 15 may be semicircular or arcuate in the top view direction, for example, the central angle of the third sidewall 14 and the central angle of the fourth sidewall 15 may be 30 °, 45 °, 60 °, 90 °, 120 °, 135 °, 150 ° or 180 °. It will be understood that, in the case where the radius of curvature of the third and fourth sidewalls 14 and 15 is fixed, the larger the central angle of the third and fourth sidewalls 14 and 15, the larger the horizontal distance between the first and second sidewalls 11 and 12, and the larger the volume of space defined by the housing 10. Conversely, the smaller the central angle of the third side wall 14 and the fourth side wall 15, the smaller the horizontal distance between the first side wall 11 and the second side wall 12, and the smaller the volume of the space defined by the housing 10. In this way, the size of the housing 10 can be adjusted according to the size of each component to be placed, so that each component is orderly and compactly arranged in the housing 10.

In an alternative embodiment, referring to fig. 13 and 15, the first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 form a cavity with open upper and lower ends, and the housing assembly 100 further includes: the middle frame 20, the middle frame 20 is arranged in the cavity. That is, the housing 10 is a hollow frame structure, and the hollow space can be used for installing and positioning the middle frame 20 and other components. That is, the case assembly 100 generally includes the case 10 at the outer side and the middle frame 20 at the inner side.

Specifically, as shown in fig. 2 and 3, the middle frame 20 includes: connecting a base shell 21 and a plurality of hollow support posts 22. The outer contour of the coupling base housing 21 matches the inner contour of the housing 10, and the coupling base housing 21 has a plurality of escape through-holes 2111 penetrating the top and bottom surfaces thereof. The hollow support column 22 is formed at the bottom of the connection base housing 21 corresponding to the escape hole 2111, and the hollow support column 22 extends from one side (e.g., the upper side of the middle frame 20 in fig. 2) to the other side (e.g., the lower side of the middle frame 20 in fig. 2).

It can be understood that, due to the matching of the connecting base shell 21 and the shape structure of the casing 10, the inner wall surface of the casing 10 and the outer wall surface of the middle frame 20 are better fitted and lean against each other to form the casing structure of the casing assembly 100.

The hollow support column 22 divides the cavity into a plurality of independent installation positioning spaces, for example, a filter element, a water pump or an adapter can be arranged in the hollow support column 22. For example, a filter cartridge can be placed into the hollow support post 22 from the bypass aperture 2111.

In addition, the number of the hollow supporting columns 22 may include one, two or more, for example, as shown in fig. 18 to 20, the number of the hollow supporting columns 22 is two, and the two hollow supporting columns 22 are arranged side by side and at an interval. It should be understood that the above description is only illustrative, and not restrictive to the embodiment of the present invention, and the number of the hollow support columns 22 may be three, and three hollow support columns 22 are formed in line side by side at the bottom of the connection base housing 21.

In an alternative example, as shown in fig. 18, the projection of the connection base shell 21 in the horizontal plane covers the projection of the hollow support column 22 in the horizontal plane. In other words, the outer circumferential edge of the connection base housing 21 exceeds the outer circumferential edge of the hollow support column 22, and after the inner frame 20 is placed in the cavity, the outer side surface of the connection base housing 21 is closer to the inner wall surface of the housing 10 than the outer side surface of the hollow support column 22.

In an alternative example, as shown in fig. 2 to 3, a plurality of hollow support columns 22 are arranged at intervals, a structural reinforcement 50 is arranged between two hollow support columns 22, and both ends of the structural reinforcement 50 are respectively connected to the outer peripheral surfaces of the two hollow support columns 22. That is, one ends (e.g., upper ends in fig. 2) of the plurality of hollow support columns 22 are connected to the connection base shell 21, and the other ends (e.g., lower ends in fig. 2) of the plurality of hollow support columns 22 are connected to the structural reinforcement member 50, so that even in the case where a member such as a filter cartridge is loaded in the hollow support columns 22, various forces can be dispersed to the structural reinforcement member 50 and the connection base shell 21, thereby improving the stability of the internal structure of the housing assembly 100. In addition, the structural reinforcement 50 may be arched, and the arched structural reinforcement 50 provides a larger force-bearing surface, thereby further improving the structural stability of the housing assembly 100.

In a further alternative embodiment, as shown in figures 2 and 18, the structural reinforcement 50 and the hollow support column 22 are provided with at least one reinforcing bead 222. The outer surface of the hollow support column 22 is provided with an interference part 221, and the reinforcing rib 221 is parallel to the interference part 221, so that the structural stability of the housing assembly 100 is further improved.

In an alternative example, as shown in fig. 10 and fig. 12, a plurality of spaced ribs 19 are formed on an inner wall surface of the housing 10, a gap 191 is formed between the ribs 19 and the inner wall surface of the housing 10, and a latch 213 engaged with the gap 191 is formed on a top portion of the connection base housing 21. Namely, the connection between the shell 10 and the middle frame 20 is realized by the cooperation of the latch 213 and the notch 191.

Wherein the ribs 19 may extend along the longitudinal direction of the housing 10, as shown in fig. 13, and the ribs 19 may also extend along the circumferential direction of the housing 10, which is not shown. By providing a plurality of ribs 19 on the inner peripheral wall of the housing 10, the structural strength of the housing 10 can be effectively increased, and the pressure resistance of the housing 10 can be improved.

In one embodiment, referring to fig. 10 in combination with fig. 12, the latch 213 is disposed on the outer periphery of the connecting base shell 21 and extends downward, the top surface of the rib 19 is recessed downward to form a notch 191 with an upward opening, and the latch 213 is inserted into the notch 191. That is, the latch 213 is inserted into the notch 191 from the top down, thereby suspending the middle frame 20 on the housing 10. Wherein, the latch 213 and the notch 191 can be in clearance or interference fit.

In a specific example, as shown in fig. 13 in combination with fig. 16, the ribs 19 include a plurality of ribs 19, and the plurality of ribs 19 are distributed on at least one of the first side wall 11, the second side wall 12, the third side wall 14, and the fourth side wall 15. In other words, a plurality of ribs 19 may be formed on the first sidewall 11 and/or the second sidewall 12 and/or the third sidewall 14 and/or the fourth sidewall 15, and preferably, a plurality of sets of ribs 19 are uniformly distributed on the first sidewall 11, the second sidewall 12, the third sidewall 14 and the fourth sidewall 15, and correspondingly, the locking tongues 213 are also uniformly distributed on the outer circumferential edge of the connecting base shell 21. Therefore, the middle frame 20 can be relatively stably arranged in the cavity by correspondingly matching the plurality of clamping tongues 213 with the plurality of notches 191.

In addition, the ribs 19 uniformly distributed on the inner wall surface of the casing 10 can also enhance the overall strength of the casing 10, and preferably, the length of the ribs 19 is substantially equal to the longitudinal length of the wall surface of the casing 10.

In a further alternative example, two ribs 19 are provided in a set, and one latch 213 corresponds to a set of the ribs 19. Namely, a latch 213 is simultaneously inserted into two notches 191. Thus, the force of the latch 213 can be distributed on the two ribs 19, and the problem of breakage of the ribs 19 can be avoided.

In a further alternative example, as shown in fig. 16, the horizontal spacing l between two adjacent ribs 19 is between 1.5 and 3.5 mm. The distance between two adjacent ribs 19 is the distance between the side surface of one rib 19 and the side surface of the other rib 19, for example, the width of the horizontal distance l is 1.5mm, 2.0mm, 2.5mm, 3.0mm, or 3.5 mm. Of course, the above-mentioned embodiments are only illustrative and should not be construed as limiting the scope of the present invention, for example, the distance between two ribs 19 may also be less than 1.5mm or greater than 3.5 mm. I.e. the horizontal spacing between two ribs 19, can be adjusted accordingly to the variations in the size of the housing 10.

In a further alternative example, as shown in fig. 14 to 16, the rib 19 includes: a connecting section 192 and a cylindrical section 193. Wherein, the connection section 192 is connected between the inner wall surface of the casing 10 and the cylindrical section 193, and has the functions of bearing the middle frame 20 and reinforcing the structural strength of the casing 10. When the middle frame 20 is inserted into the cavity, the cylindrical section 193 can play a guiding role and can abut against the outer peripheral surface of the middle frame 20 to play a limiting role. Therefore, there are relatively special requirements for the dimensions of both the cylindrical section 193 and the connecting section 192.

Specifically, as shown in fig. 14 in conjunction with fig. 16, the radial dimension r of the cross section of the cylindrical segment 193 is, for example, 1-2 mm, the diameter of the cylindrical segment 193 may be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2.0mm, and the diameter of the cylindrical segment 193 is set to be 1-2 mm, so that the cylindrical segment 193 has a small volume, does not occupy a containing cavity, can achieve guiding and positioning functions, and has strong pressure resistance, and prevents the cylindrical segment 193 from being broken or deformed inward. Of course, the diameter of the cylindrical section 193 can be increased or decreased as appropriate according to practical circumstances, for example, the diameter of the cylindrical section 193 can be between 0.5 mm and 1.0 mm, or the diameter of the cylindrical section 193 can be between 2.0mm and 5 mm.

The horizontal width d1 of the connecting section 192 is between 1 and 2 mm, the horizontal thickness d2 is between 0.5 and 1.5mm, and the vertical height h1 of the gap 191 is between 1 and 3 mm. For example, the horizontal width of the connecting section 192 may be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0mm, and the horizontal thickness of the connecting section 192 may be 0.5 mm, 0.6 mm, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm. The vertical height of the gap 191 may be 1 mm, 1.5mm, 2 mm, 2.5mm, and 3 mm, whereby the load-bearing capacity and the pressure-resistant capacity of the connection section 192 may be improved.

The water purifying apparatus 1000 according to the embodiment of the present invention includes the housing assembly 100 of the above-mentioned embodiment, and since the housing assembly 100 according to the embodiment of the present invention has high structural strength and small volume, the water purifying apparatus 1000 according to the embodiment of the present invention has high structural strength and small volume.

A water purifying apparatus 1000 according to other embodiments of the present invention will be described with reference to fig. 19 to 23.

The invention provides a water purifying apparatus 1000, and the water purifying apparatus 1000 may be a water purifier, or a water purifying apparatus 1000. As shown in fig. 19 and fig. 21, the middle frame 20 of the water purifying apparatus 1000 has two filter element cavities dd standing side by side, that is, each hollow support column 22 defines one filter element cavity dd, the water pump 71 is installed at one end of the middle frame 20 in the vertical direction, and the length direction of the water pump 71 is the same as the transverse direction of the middle frame 20, so that the arrangement of the two is more compact, and the overall volume of the water purifying apparatus 1000 can be set to be smaller.

Referring to fig. 19 to 21, the present invention provides a water purifying apparatus 1000, wherein the water purifying apparatus 1000 includes a housing 10, and the housing 10 is disposed in a vertical direction when the water purifying apparatus 1000 is in use, so that the vertical direction of the housing 10 is consistent with the vertical direction of the space. The shape of the housing 10 is specifically configured according to different requirements. In the present application, the housing 10 includes a cylindrical housing 10, an upper cover (not shown) covering an upper end of the housing 10, and a base 40 covering a lower end of the housing, so that the housing 10, the upper cover, and the base 40 form an accommodating space. The cross section of the housing 10 is arranged in a shape like a figure 8, that is, the two side plates with longer width of the housing 10 are internally provided with arc-shaped grooves extending up and down, the arrangement of the arc-shaped grooves firstly enhances the strength of the housing 10, and secondly enables the inner surface of the housing 10 to form a plurality of arc-shaped surface transitions to achieve a better noise reduction effect. In addition, a middle frame 20 is installed in the accommodating space of the housing 10, and a filter element is installed in the middle frame 20, so that the filter element filters the inlet water.

Specifically to center 20, be provided with filter core chamber dd on the center 20, filter core chamber dd can be provided with one or be provided with a plurality ofly, and when being provided with a plurality of filter core chamber dd, the mode of arranging of a plurality of filter core chamber dd can be confirmed according to the demand of difference. In this application, be provided with two filter core chambeies dd on the center 20, two filter core chambeies dd extend and are the setting side by side along upper and lower direction, from this, the arc wall on the shell 10 corresponds the interval department of two filter core chambeies dd to it makes the assembly more compact to cooperate above-mentioned shell 10.

In addition, as shown in fig. 20 and 21, a water pump 71 is installed in the casing 10, and the water pump 71 is transversely installed at one end in the vertical direction of the center frame 20. It should be explained here that the water pump 71 is placed horizontally, i.e. the length direction of the water pump 71 is aligned with the transverse direction of the middle frame 20, and therefore the middle frame 20 is placed on the water pump 71 vertically, so that the internal space of the water purifying apparatus 1000 is arranged compactly to achieve a miniaturized arrangement. The water pump 71 may be installed at the upper end of the middle frame 20, or may be installed at the lower end of the middle frame 20, and in this application, it is preferable that the water pump 71 is installed at the lower end of the middle frame 20. Therefore, considering that the filter cartridge of the present application is to be drawn out from the upper end of the middle frame 20 when the filter cartridge is cleaned or replaced, the water pump 71 is installed at the upper end of the middle frame 20 to interfere with the removal of the filter cartridge; in addition, the water pump 71 is heavy, so the water pump 71 is installed at the lower end of the middle frame 20, the overall gravity center of the water purifying apparatus 1000 can be lowered, and the effect of stable placement is achieved.

In the technical scheme of the invention, the water purifying device 1000 comprises a shell 10, a middle frame 20 is vertically arranged in the shell 10, and the middle frame 20 is provided with two filter element cavities d which are transversely arranged. Secondly, still install water pump 71 in the shell 10, water pump 71 installs the upper end or the lower extreme at center 20 to water pump 71 is horizontal setting, and the length direction of water pump 71 is unanimous with center 20's horizontal, consequently makes the assembly of both more compact, and the arrangement of reasonable water purification unit 1000 inner space to realize the miniaturization setting.

In the above embodiment, it is preferable that the water pump 71 is installed at the lower end of the middle frame 20, and the water pump 71 may be connected to the lower end of the middle frame 20, that is, the water pump 71 is connected to the middle frame 20; alternatively, the water pump 71 is fixed to the bottom of the housing 10 and is located at the lower end of the middle frame 20. In the two modes, when the water pump 71 is connected with the middle frame 20, the direct connection of the water pump 71 with the middle frame 20 can cause large transmission to the middle frame 20 to affect the filter element because the vibration generated when the water pump 71 works is large; when the water pump 71 is directly connected to the bottom of the housing 10, the vibration of the water pump 71 directly exits the housing 10, which causes the whole water purifying apparatus 1000 to shake greatly and also causes loud noise. Therefore, in another embodiment, please refer to fig. 22, the water purifying apparatus 1000 further includes a base 40, the base 40 is installed at the lower end of the middle frame 20 to form an installation cavity with the middle frame 20, and the water pump 71 is installed in the installation cavity. Specifically, referring to fig. 22 and 23, the water pump casing 41 includes a base plate 41a and a surrounding plate 41b erected along the periphery of the base plate 41a, so that the water pump casing 41 has an upper opening, and the upper end of the water pump casing 41 is connected with the middle frame 20 to form a relatively closed cavity or a completely closed cavity. The water pump 71 is installed in the installation cavity formed by the water pump case 41 and is coupled to the inner bottom surface of the base 40, thereby effectively increasing the vibration propagation resistance and the noise propagation resistance of the water pump 71. It should also be noted that the water pump housing 41 is located within the housing 10.

In order to further reduce the vibration transmission of the water pump 71, in another embodiment, referring to fig. 22, a mounting seat 74 is connected to a lower portion of the water pump 71, and the water pump 71 is mounted on the water pump housing 41 through the mounting seat 74. As will be readily appreciated, the mounting seat 74 is fixed to the inner surface of the water pump case 41, and then the water pump 71 is supported by the mounting seat 74, which is equivalent to the water pump case 41 erecting the water pump 71, so that the mounting seat 74 can primarily reduce the vibration of the water pump 71.

Further, in order to achieve a further shock absorbing effect, a plurality of shock absorbing support pads 75 are provided on the mount 74, and the plurality of shock absorbing support pads 75 support the mount 74. Therefore, when the water pump 71 works, the shockproof supporting pad 75 can further absorb shock of the water pump 71 to weaken the shock propagation of the water pump 71.

Considering that the water pump 71 is vibrated during operation, and therefore a seam is easily formed at the water receiving port of the water pump 71 to cause water leakage, referring to fig. 23, in another preferred embodiment, a water drainage hole 45 is formed through the bottom surface of the water pump housing 41, so that when water leakage occurs in the water pump 71, liquid can be drained through the water drainage hole 45 on the water pump housing 41 to avoid interference of the liquid with a wire connected to the water pump 71.

In any of the above embodiments, the water pump 71 is connected to the water path plate 72, and the water path plate 72 is provided with components such as the pressure switch 73, and the like, as shown in fig. 23. Therefore, when the water pump 71 is installed in the water pump housing 41, the water pump housing 41 interferes with the installation of the waterway plate 72 and the pressure switch 73, and further interferes with the installation of the waterway plate 72 and the pressure switch 73. Further, referring to fig. 22 and 23, in the present embodiment, a yielding notch a is formed on a side of the water passage plate 72 corresponding to the enclosing plate 41b of the water pump casing 41, so that the water passage plate 72 and the pressure switch 73 are installed at the yielding notch a.

Further, in order to reduce the influence of the opening of the abdicating notch a on the overall noise reduction effect of the water pump housing 41, in another preferred embodiment, the water pump housing 41 further includes a first cover plate (not shown), and the first cover plate covers the abdicating notch a of the enclosure plate 41b and is detachably connected to the enclosure plate 41 b. Easy understanding, because original papers such as water route board 72 arrange in the breach a department of stepping down, when first apron lid closed the breach a of stepping down, first apron itself has certain holding position and supplies elements such as water route board 72 to hold, for example the lid accommodation space is sunken to form by the face of first apron, perhaps first apron is certain radian setting, consequently can enclose and establish breach a department of stepping down and will should step down breach a and enclose stifled.

Before the water purifying apparatus 1000 is used, the air tightness of the water purifying apparatus 1000 is generally detected to prevent water leakage during the use of the water purifying apparatus 1000. In a general detection method, the detection gas inlet pump 71 and each water channel are filled, and then the detection probes are used to detect whether there is a gas leakage or not by approaching the water inlet and the water outlet e of the water pump 71 (as shown in fig. 20, the detection probes are disposed adjacent to the water inlet) and the connection port connected to the water channel plate 72. In this regard, on the basis of the above embodiment, since the water pump case 41 and the middle frame 20 cooperate to form a closed cavity for placing the water pump 71, when the air tightness of the water purifying apparatus 1000 is detected by the inspector, it is troublesome to open the water pump case 41 and then approach the monitoring head to each flow path structure of the water pump 71.

Referring to fig. 19 to 21, the present invention provides a water purifying apparatus 1000, wherein the water purifying apparatus 1000 includes a housing 10, and the shape of the housing 10 is specifically configured according to different requirements. In the present application, the housing 10 includes a cylindrical housing 10, an upper cover (not shown) covering upper and lower ends of the housing 10, and a base 40, so that the housing 10, the upper cover, and the base 40 are assembled to form an accommodating space. The cross section of the casing 10 is arranged in a shape like a figure 8, that is, the two side plates with longer width of the casing 10 are internally provided with arc-shaped grooves extending up and down, the arrangement of the arc-shaped grooves firstly enhances the strength of the casing 10, and secondly enables the inner surface of the casing 10 to form a plurality of arc-shaped surface transitions to achieve a better noise reduction effect. In addition, a middle frame 20 is installed in the accommodating space of the housing 10, and a filter element is installed in the middle frame 20, so that the filter element filters the inlet water.

The lower end of the middle frame 20 is provided with a water pump shell 41, the water pump shell 41 and the bottom plate of the middle frame 20 enclose to form an installation cavity, and a water pump 71 is installed in the installation cavity. As can be easily understood, the water pump case 41 is installed at the bottom of the middle frame 20, and then the water pump 71 is installed in the water pump case 41, and firstly, because the formed accommodating space is small, after the water pump 71 is installed in the water pump case 41, the propagation resistance of the noise generated by the water pump 71 in the small space is large, and the sound waves generate interference, so that the noise reduction effect can be achieved preliminarily; secondly, because the water pump shell 41 is installed in the shell 10, and the water pump 71 is installed in the water pump shell 41, the noise generated by the water pump 71 is blocked by the double-layer shell plates (the water pump shell 41 and the shell 10), and the propagation resistance of the noise is greatly increased, thereby achieving excellent noise reduction effect. It should be noted that the shape of the water pump housing 41 may be set to meet different requirements, and in the present embodiment, in order to match the shape of the housing 10, the sectional shape of the water pump housing 41 is preferably set to correspond to the shape of the housing 10.

It is easy to understand that a plurality of second wire clamping structures 430 distributed at intervals are further arranged on the wall of the wire harness slot 410, so that after the water pump power line is arranged in the wire harness slot 410, the part of the wire body accommodated in the wire harness slot 410 can be clamped through the cooperation of the first wire clamping structure 420 and the second clamping structure, thereby not only preventing the water pump power line from being pulled easily, but also preventing the water pump power line from being pulled out of the wire harness slot 410. The second wire-clamping structure 430 may also refer to the setting of the first wire-clamping structure 420, and in this embodiment, the second wire-clamping structure 430 is preferably a glue dot coated on the groove wall of the wiring groove 410.

In another embodiment, referring to fig. 28 and 29, an adhesive strip 440 is disposed on at least one groove wall of the bundling groove 410, and the adhesive strip 440 is fixed to the groove wall of the bundling groove 410 and extends along the extension of the bundling groove 410 in a square shape. As can be easily understood, the adhesive tape 440 is disposed on the wall of the wire-tying groove 410, so that after the water pump power line is accommodated in the wire-tying groove 410, the adhesive tape 440 protruding from the wall of the wire-tying groove 410 clamps the water pump power line to enhance the fixing strength of the water pump power line. The adhesive tape 440 may be provided in a continuous manner or may be provided intermittently in the adhesive tape 440. Moreover, the tape 440 may be provided on one groove wall of the harness groove 410, or the tapes 440 may be provided on both groove walls of the harness groove 410.

In yet another embodiment, referring to fig. 30 and 31, the trunking 410 has a notch opposite to the bottom of the slot, and the edge of the notch is protruded inwards with a limit protrusion 450. Specifically, the limiting protrusion 450 is formed by inward protruding of the edge of the notch, and the thickness of the limiting protrusion 450 is small so as to have certain deformation capacity, so that when the water pump power line is placed in the wire harness slot 410, the water pump power line is firstly pressed to cause the limiting protrusion 450 to be bent and deformed towards the bottom of the slot, and then when the water pump power line is accommodated in the wire harness slot 410, the limiting protrusion 450 is restored to the original state so as to limit the water pump power line in the wire harness slot 410 to be placed in the wire harness slot 410 and be pulled out.

On the basis of any of the above embodiments, referring to fig. 26, 28 and 30, a lead fixing structure 460 is further disposed on the bottom surface of the base 40, and the lead fixing structure 460 is disposed adjacent to the outlet N. As will be readily understood, since the external power line of the water pump power line extending from the outlet N of the wire harness slot 410 is located outside the housing 10, when the portion of the wire body extending outside the housing 10 is subjected to a pulling force, the water pump power line is pulled to disengage from the outlet N of the wire harness slot 410, which results in the wire inside the whole wire harness slot 410 disengaging. Therefore, in the present embodiment, the wire fixing structure 460 is disposed at the wire outlet N of the adjacent wire-bundling slot 410, so as to fix the wire body at the wire outlet N of the wire-bundling slot 410, thereby avoiding the above-mentioned problems.
