Referring to fig. 1 and 2, in an embodiment of the separating assembly 10 for separating dust from gas, at least the manufacturing process is simple, the manufacturing cost is low, and the processing efficiency is high. Specifically, the separation assembly 10 includes a cyclonic separator 100 and a bracket 200.

Referring to fig. 3 to 5, the cyclone separator 100 includes a plurality of cyclone units 110 and a connection rib 120, the cyclone units 110 are arranged in parallel, and longitudinal axes a of the cyclone units 110 are arranged in parallel. Two adjacent cyclone units 110 are connected by a connection rib 120, the connection rib 120 is deformable, and a single cyclone unit 110 can be deflected relative to another adjacent cyclone unit 110 by the connection rib 120 to gather one ends of the cyclone units 110.

When processing, the cyclone units 110 are arranged in such a manner that the cyclone units 110 are arranged in parallel and connected by the connecting ribs 120 to form the cyclone separator 100. Because the longitudinal axes a of the cyclone units 110 are parallel to each other, on one hand, the cyclone units 110 can be subjected to injection molding along the direction of the longitudinal axes a, the processing directions of the cyclone units 110 are consistent, and the mold stripping directions after processing are consistent, so that the processing efficiency can be effectively improved, and the processing cost can be reduced. On the other hand, the mould for processing the cyclone separator 100 can be effectively simplified, the mould cost is reduced, and the processing precision is convenient to improve. When the cyclone separator is installed and used, the connecting ribs 120 can be deformed, so that under the action of certain thrust, the single cyclone unit 110 deflects relative to the adjacent other cyclone unit 110 through the connecting ribs 120, one ends of the cyclone units 110 are gathered, the cyclone units 110 are in a radial inclined arrangement state, the size of the cyclone separator 100 at one end of the cyclone unit 110 can be reduced, the space utilization rate is improved, and the overall size of the cyclone separator 100 is reduced.

In this embodiment, the plurality of cyclone units 110 are arranged in an annular structure, each cyclone unit 110 includes an air inlet 112 and a cone portion 114 arranged on the air inlet 112, an air inlet 111 is formed on the air inlet 112, a dust outlet 115 is formed at one end of the cone portion 114 opposite to the air inlet 112, and the cone portion 114 can deflect towards the direction of the center line of the annular structure, so that one end of the cone portion 114, which is far away from the air inlet 112, is gathered. The plurality of cyclone units 110 are arranged in an annular structure, so that dust-carrying gas can conveniently enter the cone portion 114 from the gas inlet 111, and dust is discharged from the dust discharge port 115 on the cone portion 114 in the cone portion 114 due to centrifugal force and gravity, so that the separation of dust in the gas is realized. During processing, the plurality of cyclone units 110 are arranged in a ring structure; when the cyclone separator 100 is installed, the size of the cone part 114 is gradually reduced towards the direction far away from the air inlet part 112, so that one end of the cone part 114 far away from the air inlet part 112 is gathered, the structural compactness of the cyclone separator 100 can be effectively improved, and the size of the cyclone separator 100 is reduced.

In other embodiments, the cyclone units 110 may be arranged in a row, and the longitudinal axes a of the cyclone units 110 are parallel to each other. When the cyclone unit is required to be installed, the first cyclone unit 110 and the last cyclone unit 110 in a row are close to each other, so that the cyclone units 110 are arranged in a ring structure. The cone parts 114 of the cyclone units 110 are further deflected through the connecting ribs 120, one ends, far away from the air inlet part 112, of the cone parts 114 of the cyclone units 110 are gathered, and then a radial inclined arrangement state that the cone parts 114 are gathered and gradually separated towards the air inlet part 112 is formed, so that the size of the cyclone separator 100 can be effectively reduced, and the structure is more compact.

In one embodiment, the cyclone units 110 are arranged at equal intervals, and two adjacent cyclone units 110 are directly connected by the connecting rib 120. And then make two adjacent whirlwind units 110 only connect through splice bar 120, avoid setting up the deflection that other connecting portions influence whirlwind unit, a plurality of whirlwind units 110 equidistant setting and then make the equidistant setting of air inlet 111 simultaneously, and then can effectively improve stability and the homogeneity of admitting air, improve gas-dust separation efficiency.

Specifically, the air inlet 112 of the cyclone unit 110 is further formed with an exhaust port 113, and the exhaust port 113 is disposed opposite to the dust discharge port 115. The gas separated from the dust can be effectively discharged from the gas outlet 113, and the gas discharge efficiency is improved.

Further, the air inlet 111 is opened on a side wall of the air inlet 112, and an opening of the air inlet 111 is tangential to an inner wall of the air inlet 112. Thereby enabling the gas introduced through the gas inlet 111 to be efficiently rotated in the cyclone unit 110.

In the present embodiment, the air inlet 112 is cylindrical to facilitate the opening of the air inlet 111. In other embodiments, the air inlet portion 112 may also be conical, with the air inlet portion 112 smoothly transitioning to the conical portion 114.

In this embodiment, both ends of the connection rib 120 are integrally formed on the adjacent two cyclone units 110, respectively. The processing difficulty can be further reduced, and the connection stability of two adjacent cyclone units 110 can be effectively improved through the connecting ribs 120.

In one embodiment, the two ends of the connecting rib 120 are respectively disposed at the air inlets 112 of two adjacent cyclone units 110. When the end of the cone portion 114 far away from the air inlet portion 112 is gathered, the position change range of the air inlet portion 112 is small, and therefore the size of the cyclone separator 100 during installation and use can be effectively reduced.

In another embodiment, both ends of the connection rib 120 are respectively disposed at the connection part of the air inlet part 112 and the cone part 114 of two adjacent cyclone units 110. When the end of the tapered portion 114 away from the air inlet portion 112 is gathered, the amplitude of the change in the position of the air inlet portion 112 is reduced.

Of course, both ends of the connection rib 120 may be disposed at the portions of the cone portions 114 of the adjacent two cyclone units 110 near the air inlet portion 112. When the end of the tapered portion 114 away from the air inlet portion 112 is gathered, the amplitude of the change in the position of the air inlet portion 112 is reduced.

In this embodiment, the connection rib 120 is a cylindrical structure, and then the connection stability of two adjacent cyclone units 110 can be improved, so that the connection rib 120 is simple to process and high in stability. In other embodiments, the connection rib 120 may also have a strip structure or other shape structure, as long as it can connect two adjacent cyclone units 110, and facilitate the deflection of a single cyclone unit 110 relative to another adjacent cyclone unit 110.

Optionally, the diameter of the connecting rib 120 is 1mm-4mm, so that the problem that the stability of connection between two adjacent cyclone units 110 is affected due to too small diameter of the connecting rib 120 is avoided; the diameter of the connecting rib 120 is prevented from being too large, and the deflection of the cyclone unit 110 through the connecting rib 120 is prevented from being influenced.

In the present embodiment, the diameter of the connection rib 120 is 2mm, that is, the connection stability of two adjacent cyclone units 110 can be ensured, and the deflection of the cyclone units 110 through the connection rib 120 can be conveniently realized. Of course, in other embodiments, the diameter of the connecting rib 120 may be greater than or less than 2 mm.

Referring to fig. 2 and fig. 6, in an embodiment, the bracket 200 includes a base 210, the base 210 is provided with a plurality of positioning holes 212 arranged at intervals, and a distance between center lines of two adjacent positioning holes 212 is smaller than a distance between longitudinal axes a of two adjacent cyclone units 110 arranged in parallel; each cyclone unit 110 is correspondingly inserted into a positioning hole 212.

When the cyclone separator is installed and used, the distance between the center lines of the positioning holes 212 on the base 210 of the bracket 200 is smaller than the distance between the longitudinal axes a of the two adjacent cyclone units 110 arranged in parallel, and the connecting ribs 120 are deformable, so that the single cyclone unit 110 deflects relative to the other adjacent cyclone unit 110 through the connecting ribs 120 under the action of certain thrust, one ends of the cyclone units 110 are gathered, each cyclone unit 110 is correspondingly inserted into one positioning hole 212, the cyclone separator 100 can be effectively supported through the bracket 200, and the installation position of the cyclone separator 100 on the base 210 can be effectively limited through the positioning holes 212. Because one end of the cyclone units 110 is gathered, the size of the cyclone separator 100 at one end of the cyclone units 110 can be reduced, a radial inclined arrangement state is formed, the space utilization rate is improved, and the overall size of the separation assembly 10 is reduced.

Optionally, the positioning holes 212 are annularly arranged, so that the cyclone units 110 can be effectively annularly arranged, and dust-laden gas can enter the gas inlet 111 conveniently.

Specifically, the base 210 is further provided with a mounting hole 214, the mounting hole 214 is located in a ring formed by the plurality of positioning holes 212, and the mounting hole 214 is used for mounting the single cyclone unit 110. The provision of the mounting apertures 214 enables the cyclone units 110 to be further mounted within the annular arrangement formed by the cyclonic separator 100 and the separation of dust from the dusty gas by the separation assembly 10 to be further enhanced.

Alternatively, the number of the mounting holes 214 may be plural, and one cyclone unit 110 may be installed in each mounting hole 214. Specifically, the number of the mounting holes 214 is four, and four mounting holes 214 are provided at intervals. Of course, the number of mounting holes 214 may also be two, three or another number. Of course, in other embodiments, the mounting holes 214 may also be omitted.

Optionally, an air inlet is opened on the base 210, and the dust-laden air can enter the air inlet 111 through the air inlet. Specifically, the base 210 is not provided with a hollow-out portion for forming the air inlet hole, so that the base 210 is reasonable in structural utilization, and the air inlet efficiency and uniformity are improved by effectively enlarging the size of the air inlet hole.

Referring to fig. 3 and 6, in an embodiment, the cyclone unit 110 is formed with a first limiting portion 116, the base 210 is formed with a first limiting groove 216, and the first limiting portion 116 can be inserted into the first limiting groove 216. The stability of the cyclone unit 110 in the positioning hole 212 can be effectively improved by arranging the first limiting part 116 and the first limiting groove 216, and the cyclone unit 110 is prevented from shaking in the positioning hole 212.

Specifically, the first position-limiting portion 116 is formed on the cone portion 114 of the cyclone unit 110, the base 210 is formed with a boss 218, and the boss 218 is provided with a first position-limiting groove 216.

In the present embodiment, a first limiting groove 216 is correspondingly formed on one side of each positioning hole 212, so that the positioning stability of the cyclone unit 110 on the base 210 can be effectively improved, and the cone portion 114 of a single cyclone unit 110 is prevented from deflecting, thereby affecting the determination of the installation position of the air inlet 111 on the air inlet portion 112. Specifically, a boss 218 is correspondingly disposed on one side of each positioning hole 212, and a limiting groove is disposed on each boss 218.

Specifically, a support portion 224 is formed on an inner wall of the support member 220, and the support portion 224 can abut on the cyclone unit 110. After the cyclone unit 110 is inserted into the positioning hole 212, the supporting portion 224 can abut against the cyclone unit 110, so as to effectively support the cyclone unit 110, and improve the stability of the cyclone unit 110 in the installation cavity 222.

Specifically, the inner wall of the single support portion 224 facing the cyclone unit 110 is tangent to the inner wall of the corresponding positioning hole 212. After the cyclone unit 110 is inserted into the positioning device, the inner wall of the supporting portion 224 can be effectively attached to the cyclone unit 110, so as to provide more stable support for the cyclone unit 110.

Further, the support portion 224 may abut against the tapered portion 114, and an inner wall of the support portion 224 facing the cyclone unit 110 is an arc surface matching the tapered portion 114. When the supporting portion 224 abuts against the cyclone unit 110, the inner wall can be stably attached to the cyclone unit 110, and the cyclone unit 110 is further stably supported.

Of course, in other embodiments, the supporting portion 224 may also be a protrusion disposed on the inner wall of the supporting member 220, and the protrusion can abut on the cyclone unit 110. Alternatively, the supporting portion 224 may be omitted, and the inner wall of the supporting member 220 directly abuts on the cyclone unit 110 to provide support for the cyclone unit 110.

In the embodiment, the boss 218 and the supporting portion 224 with the first positioning groove 216 are disposed on two opposite sides of the positioning hole 212, respectively. Of course, the boss 218 and the support portion 224 may not be disposed opposite to each other as long as the cyclone unit 110 can be supported.

In an embodiment, the cyclone unit 110 further has a second limiting groove 117 formed thereon, the supporting member 220 has a second limiting portion 226 formed thereon, and the second limiting portion 226 can be inserted into the second limiting groove 117. The stability of the cyclone unit 110 disposed on the supporter 220 is further improved by forming the second stopper 226 to be engaged with the second stopper groove 117.

Optionally, a clamping table 118 is formed on an outer wall of the cyclone unit 110, the second limiting groove 117 is opened on the clamping table 118, the second limiting portion 226 is formed on one side of the supporting member 220 facing away from the base 210, and the clamping table 118 can abut against one side of the supporting member 220 facing away from the base 210, so that the second limiting portion 226 can be inserted into the second limiting groove 117. The clamping table 118 abuts against one side, opposite to the base 210, of the support piece 220, so that the position of the cyclone unit 110 in the installation cavity 222 can be further limited, and the stability of the cyclone separator 100 in the installation cavity 222 can be further improved.

Specifically, the catch 118 is formed at a position where the tapered portion 114 is close to the air intake portion 112. When the tapered portion 114 is inserted into the positioning hole 212, the supporting portion 224 abuts against the tapered portion 114, so that the locking stand 118 abuts against a side of the supporting member 220 opposite to the base 210, and the tapered portion 114 can be supported more effectively. Of course, in other embodiments, the catch 118 may also be formed on the air inlet portion 112, or the catch 118 may also be formed at the connection of the air inlet portion 112 and the cone portion 114.

In another embodiment, a second limiting portion may be further formed on an outer wall of the cyclone unit 110, and the supporting member 220 is provided with a second limiting groove, so long as the cyclone unit 110 can be positioned on the supporting member 220 by the cooperation of the second limiting portion and the second limiting groove.

In one embodiment of a vacuum cleaner, which includes the separating assembly 10 and the dust collector in any of the above embodiments, the bracket 200 is disposed on the dust collector, and the positioning hole 212 is communicated with the dust collecting chamber. The dust-laden gas enters the cone portion 114 from the gas inlet 111 of the cyclone unit 110, and the dust is discharged from the cone portion 114 to the dust discharge port 115 at one end of the gas inlet 112 due to centrifugal force and gravity in the cone portion 114. Because the cone part 114 is inserted into the positioning hole 212 and the dust collecting cavity are arranged, dust can effectively fall into the dust collecting cavity, and the separation of the dust in the gas is realized.

The above-mentioned embodiments only express a few embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
