Background

Food crushing devices such as a blender, a soymilk grinder and the like comprise hole-shaft matching structures, and gaps between through holes and rotating shafts are generally required to be sealed in the operation process of the food crushing devices. The prior art food crushing device generally comprises a container with a through hole, a rotating shaft penetrating through the through hole on the container and a sealing ring sleeve positioned between the rotating shaft and the wall of the through hole. The sealing ring sleeve can seal a gap between the rotating shaft and the container to a certain degree. However, since the rotating shaft needs to rotate in the hole, the rotating shaft radially extrudes the sealing ring sleeve to cause the deviation of the sealing ring, and the phenomenon of damaging the sealing property between the rotating shaft and the container occurs sometimes.

Disclosure of Invention

Therefore, the technical problem to be solved by the present invention is to overcome the defect that the sealing structure of the food crushing device in the prior art easily loses the sealing performance of the gap between the through hole and the rotating shaft during the rotation of the rotating shaft, so as to provide a food crushing device capable of reliably sealing the gap between the through hole and the rotating shaft.

In order to solve the above problems, the present invention provides a food crushing apparatus comprising: the container is provided with an assembly cavity, and a through hole is formed in the assembly cavity; a rotating shaft inserted into the assembly cavity and in clearance fit with the through hole; the sealing ring sleeve is arranged in the assembly cavity and sleeved on the rotating shaft, and can shield a gap between the container and the rotating shaft; the limiting part comprises a ring body sleeved on the rotating shaft and a limiting convex part which is arranged on the ring body along the circumferential direction and extends along the axial direction, a limiting groove matched with the limiting convex part is arranged on the sealing ring sleeve, and the hardness of the limiting convex part is greater than that of the sealing ring sleeve.

Furthermore, the sealing ring sleeve is provided with a base part and a fork part connected with the base part, the fork part extends to the outer wall of the rotating shaft, and the base part is provided with a limiting groove matched with the limiting convex part.

Further, the fork portion is a plurality of, and a plurality of fork portions are set up on the inner wall of base along the direction of height.

Furthermore, the limiting part is arranged on one side, away from the through hole, of the sealing ring sleeve, and the food crushing device further comprises an anti-falling part which is arranged on one side, away from the sealing ring sleeve, of the limiting part and abuts against the limiting part.

Further, the anti-dropping piece is a hole check ring.

Further, a circumferential annular groove is formed in the inner circumferential wall of the assembling cavity, and a retainer ring for the hole is embedded into the circumferential annular groove.

Further, the food crushing device also comprises a bearing assembly sleeved on the rotating shaft, and the bearing assembly is farther away from the through hole than the limiting piece.

Further, the bearing assembly comprises a first bearing, a second bearing and a bushing, wherein the first bearing and the second bearing are sequentially sleeved on the rotating shaft along the axial direction, and the bushing is arranged between the first bearing and the second bearing.

Further, the inner wall of the bushing has a groove portion thereon.

Further, the assembly cavity comprises a first sub-cavity, a second sub-cavity, a third sub-cavity and a fourth sub-cavity which are sequentially connected in the axial direction, a circumferential annular groove is formed in the first sub-cavity, and a first bearing, a lining and a second bearing are respectively arranged in the second sub-cavity, the third sub-cavity and the fourth sub-cavity.

Further, the food crushing device also comprises an outer diameter check ring which is detachably connected with the container and shields the opening of the assembly cavity, and the inner diameter of the outer diameter check ring is smaller than the outer diameter of the second bearing.

Furthermore, the food crushing device also comprises a flat washer, an elastic washer and a check ring for a shaft, which are sequentially sleeved on the rotating shaft, wherein the flat washer is positioned on one side of the second bearing, which is far away from the bushing.

Further, the food crushing device is a soymilk grinder.

The invention has the following advantages:

according to the technical scheme, the limiting piece capable of being sleeved on the rotating shaft is additionally arranged, and the limiting groove is formed in the sealing ring sleeve. The limiting part can be sleeved on the rotating shaft through the ring body and inserted into the limiting groove by the aid of the limiting convex part. Because the hardness of the limiting convex part is set to be larger than that of the sealing ring sleeve, when the rotating shaft rotates in the through hole and radially extrudes the sealing ring sleeve, the limiting convex part can radially support the sealing ring sleeve and prevent the sealing ring sleeve from being extruded and deviating, and the risk that the sealing ring sleeve loses the sealing effect because the sealing ring sleeve is extruded by the rotating shaft is reduced. Therefore, the food crushing device can overcome the defects that the sealing ring sleeve is easily extruded by the rotating shaft in the rotating process and loses the sealing performance between the rotating shaft and the through hole, and can reliably seal the gap between the through hole and the rotating shaft.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Fig. 1 schematically shows a food crushing device according to an embodiment of the invention. Fig. 2 is a container of the food crushing device of fig. 1. Although the food crushing device 100 is a soymilk maker in the present embodiment, in other embodiments, the food crushing device 100 may be selected from a food processor, a juicer, an oil press, or the like. The food crushing device 100 of the present embodiment mainly includes a container 1, a rotating shaft 2, a sealing ring sleeve 3, and a stopper 4. Wherein, a fitting cavity 11 is formed on the container 1. A through hole is arranged in the assembly cavity 11. The rotating shaft 2 is inserted into the fitting cavity 11 and is in clearance fit with the through hole. The sealing ring sleeve 3 is arranged in the assembly cavity 11 and sleeved on the rotating shaft 2, and can shield a gap between the container 1 and the rotating shaft 2. The limiting piece 4 is sleeved on the rotating shaft 2. The stopper 4 includes a ring body 41 and a stopper protrusion 42 provided on the ring body 41 in the circumferential direction and extending in the axial direction. The sealing ring sleeve 3 is provided with a limit groove 34 matched with the limit convex part 42. The stop boss 42 has a hardness greater than the hardness of the sealing collar. When the food crushing device 100 is selected to be a soymilk maker, the container 1 may be selected to be a heating plate. When the food crushing device 100 is selected as a juicer, the container 1 may be selected as a cup, which is well known to those skilled in the art and will not be described in detail herein. The lower end of the rotating shaft 2 is connected with a rotating source, and the rotating source can be selected as a device capable of outputting rotation, such as an electric motor, an engine, a hydraulic motor or a combination of one of the electric motor, the engine and the hydraulic motor and a speed reducer. Preferably, the motor shaft transmits power to the rotating shaft 2 through the coupling, and the rotating shaft 2 rotates with the container 1. The sealing collar 3 is preferably made of, but not limited to, a material such as rubber or silicone that is resilient and has suitable mechanical strength.

According to the above technical solution, the limiting member 4 capable of being sleeved on the rotating shaft 2 is added to the food crushing device 100 of the embodiment, and the limiting groove 34 is formed in the sealing ring sleeve 3. The limiting member 4 can be sleeved on the rotating shaft 2 through the ring body 41 and inserted into the limiting groove 34 by the limiting protrusion 42. Since the hardness of the convex stopper 42 is set to be greater than that of the seal ring 3, when the rotary shaft 2 rotates in the through hole and radially presses the seal ring 3, the convex stopper 42 can radially support the seal ring 3 and prevent the seal ring 3 from being pressed and displaced, resulting in loss of sealing of the gap between the container 1 and the rotary shaft 2. Therefore, the food crushing device 100 of the present embodiment can solve the defect that the sealing ring housing 3 is easily pressed by the rotating shaft 2 during rotation and loses the sealing property between the rotating shaft 2 and the through hole, and can reliably seal the gap between the through hole and the rotating shaft 2.

In the present exemplary embodiment, the sealing collar 3 has a base 31 and a fork 32 connected to the base 31. The fork 32 extends to the outer wall of the shaft 2, which enables the fork 32 to abut against and be compressed by the surface of the shaft 2. When the rotating shaft 2 rotates in the through hole and causes the sealing ring sleeve 3 to deviate, the fork 32 on the sealing ring sleeve 3 can restore to the original shape through the self elastic restoring force and continue to be in sealing connection with the surface of the rotating shaft 2, so that the risk that the sealing ring sleeve 3 loses the sealing effect on the gap between the through hole and the rotating shaft 2 is reduced. The base 31 is provided with a limit groove 34 matched with the limit projection 42.

The number of the fork 32 is preferably plural. A plurality of fork portions 32 are provided on the inner wall of the base 31 in the height direction. When the fork portion 32 is provided in plural, the plurality of fork portions 32 not only can perform multiple sealing to the gap between the through hole and the rotating shaft 2, but also can make the plurality of fork portions 32 disperse each other and form a certain included angle with the surface of the rotating shaft 2 when the fork portions 32 are pressed against the rotating shaft 2. As shown in fig. 3, when liquid falls from the gap between the through hole and the rotating shaft 2 onto the fork 32 of the seal ring housing 3, the pressure applied by the liquid to the fork 32 can be converted into a pressing force of the fork 32 to the rotating shaft 2, thereby further enhancing the sealing effect of the seal ring housing 3. Therefore, the more liquid flows onto the fork 32, the greater the pressing force of the fork 32 on the shaft 2, and the better the sealing effect of the sealing ring sleeve 3.

No excessive limit is made to the number of the fork 32. For example, in the present embodiment, the number of the fork portions 32 is preferably set to 2. This allows both the fork 32 to press against the shaft 2 and convert the pressure of the liquid against the fork 32 into a pressing force of the fork 32 against the shaft 2, and the thickness of the individual fork 32 to be set larger to increase the pressing force that the individual fork 32 can apply to the shaft 2 when pressed by the shaft 2. Preferably, as shown in fig. 3, in this embodiment, the base 31 of the sealing ring sleeve 3 is further provided with a retaining protrusion 33 for abutting against the cavity wall of the assembly cavity 11. As shown in fig. 5, the slip-off preventing protrusions 33 not only can apply pressure to the fitting cavity 11 and increase the maximum static friction between the seal ring housing 3 and the fitting cavity 11, thereby preventing the seal ring housing 3 from sliding along the fitting cavity 11, but also can be compressed by the cavity wall of the fitting cavity 11, thereby increasing the pressing force of the fork 32 against the shaft 2.

In the present exemplary embodiment, the limiting element 4 is arranged on the side of the sealing collar 3 remote from the through-opening. The food crushing device 100 further comprises a separation preventing part 5 which is arranged on one side of the limiting part 4 far away from the sealing ring sleeve 3 and is abutted against the limiting part 4. The separation preventing member 5 can prevent the separation of the limiting member 4 from the fitting cavity 11. The release preventing member 5 is preferably, but not limited to, a hole retainer ring. As shown in fig. 4 and 7, the hole stopper is provided with a pair of tool holes adapted to allow a tool such as a pliers to pass through. The operator can grip the two tool holes with a tool such as pliers and reduce the outer diameter of the circlip, thereby allowing the circlip to be put into the fitting cavity 11. Preferably, a circumferential ring groove 11a is provided on the inner circumferential wall of the fitting cavity 11. The retainer ring for hole is fitted into the circumferential annular groove 11a, and the reliability of the retainer ring for hole in the position limitation of the stopper 4 and the seal ring housing 3 can be further improved.

In this embodiment, as shown in fig. 4, the food crushing device 100 further includes a bearing assembly 6 sleeved on the rotating shaft 2, and the bearing assembly 6 is further away from the through hole than the stopper 4. The bearing assembly 6 can limit the rotation range of the rotary shaft 2 while reducing friction generated during rotation of the rotary shaft 2. The bearing assembly 6 may optionally comprise a first bearing 61 and a second bearing 62 which are sequentially sleeved on the rotating shaft 2 along the axial direction. Preferably, however, a bushing 63 is provided between the first bearing 61 and the second bearing 62. The bushing 63 can not only withstand the vibration generated during the rotation of the first bearing 61 and the second bearing 62, but also help to extend the distance between the first bearing 61 and the second bearing 62, and further improve the stability of the rotating shaft 2 during the rotation, and also facilitate the replacement of the bushing 63 itself after being damaged. Bushing 63 may be selected from relatively soft, low cost materials such as soft metals, rubbers, nylon, and non-metallic polymers. To further facilitate replacement of the bushing 63, the inner wall of the bushing 63 preferably has a groove 631 therein.

In the present embodiment, as shown in fig. 2, the assembly chamber 11 includes a first sub-chamber 111, a second sub-chamber 112, a third sub-chamber 113 and a fourth sub-chamber 114 which are connected in sequence along the axial direction. A circumferential ring groove 11a is formed in the first sub-chamber 111, and the first bearing 61, the bush 63 and the second bearing 62 are respectively disposed in the second sub-chamber 112, the third sub-chamber 113 and the fourth sub-chamber 114. The length of the assembly cavity 11 is divided by the sub-cavities, so that the machining error of increasing the assembly cavity 11 due to the fact that the length of the assembly cavity 11 is long is avoided. In addition, the inner diameters of the first sub-cavity 111, the second sub-cavity 112, the third sub-cavity 113 and the fourth sub-cavity 114 can be set to be increased in sequence, and a circumferential convex brim is formed at the joint of every two sub-cavities. The first bearing 61, the bush 63 and the second bearing 62 can abut against one circumferential ledge, respectively, and contribute to enhancing the assembling strength of the bearing assembly 6.

In this embodiment, the food crushing device 100 further comprises an outer diameter collar 7 detachably connected to the container 1 and shielding the opening of the fitting cavity 11. The inner diameter of the outer diameter retainer 7 is smaller than the outer diameter of the second bearing 62. The bearing assembly 6 can be confined in the fitting cavity 11. The connection between the collar 7 and the container 1 is waterproof, optionally a snap connection or a screw connection or the like, but preferably a firm and reliable screw connection (see fig. 6).

In this embodiment, the food crushing device 100 further comprises a flat washer 81, an elastic washer 82 and a shaft retainer 83 which are sequentially sleeved on the rotating shaft 2. A flat washer 81 is located on the side of the second bearing 62 remote from the bush 63. The shaft collar 83 can rotate along with the rotation shaft 2. The elastic washer 82 can be pressed against the flat washer 81 by the shaft retainer 83 and applies a pressing force to the inner ring of the bearing assembly 6 by means of the flat washer 81 and drives the inner ring of the bearing to rotate together when the rotating shaft 2 rotates, reducing the risk of the bearing not rotating and causing wear to the rotating shaft 2.

In summary, the food crushing device 100 of the present embodiment can overcome the defect that the sealing structure of the food crushing device 100 in the prior art easily loses the sealing property of the gap between the through hole and the rotating shaft 2 during the rotation of the rotating shaft 2.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
