[0055] Further, the rolling brush assembly 100 provided by the embodiments of the present disclosure further comprises a rolling brush cabin 30 and a support 20, the rolling brush cabin 30 is provided with an open mounting space, and there is a gap between the free end of the first rolling brush 11 and the second rolling brush 12 and the rolling brush cabin wall. The support 20 is arranged in the rolling brush cabin 30, the first rolling brush 11 and the second rolling brush 12 are connected to the support 20, the support 20 has at least a first attitude and a second attitude, when the support 20 is in the first attitude, the first rolling brush 11 and the second rolling brush 12 are located in the rolling brush cabin 30, when the support is in the second attitude, the free end of the first rolling brush 11 and the second rolling brush 12 is raised.

[0056] The parts of the rolling brush assembly 100 provided by the embodiments of the present disclosure will be described in detail below:

[0057] The support 20 is used for mounting the first brush body 111 and the second brush body 121, as shown in FIG. 3, the support 20 can comprise a frame body 21, a first mounting shaft 22 and a second mounting shaft 23, the first mounting shaft 22 and the second mounting shaft 23 are arranged through the frame body 21, and the first mounting shaft 22 and the second mounting shaft 23 can rotate relative to the frame body 21. The first mounting shaft 22 and the second mounting shaft 23 are arranged in parallel, the first rolling brush 11 is mounted on the first mounting shaft 22, and the second rolling brush 12 is mounted on the second mounting shaft 23.

[0058] The support 20 has at least a first posture and a second posture. When the support 20 is in the first posture, the first roller brush 11 and the second roller brush 12 are located in the roller brush cabin 30, and the first mounting shaft 22 and the second mounting shaft 23 are in a horizontal state. As shown in FIG. 4, when the support 20 is in the second posture, the free ends of the first roller brush 11 and the second roller brush 12 are raised, and at this time, the user can easily remove the first roller brush 11 and the second roller brush 12.

[0059] In an example, the support 20 is provided with a first connecting lug and a second connecting lug. The first connecting lug and the second connecting lug are oppositely arranged, and have a spacing therebetween. The roller brush cabin 30 has a connecting portion located between the first connecting lug and the second connecting lug. The connecting portion is provided with a first connecting shaft and a second connecting shaft. The first connecting lug is provided with a first connecting hole, and the first connecting shaft is arranged in the first connecting hole and can rotate in the first connecting hole. The second connecting lug is provided with a second connecting hole, and the second connecting shaft is arranged in the second connecting hole and can rotate in the second connecting hole.

[0060] In some embodiments, the first connecting hole can be an arc-shaped long hole, and the second connecting hole can be an arc-shaped long hole. By arranging the first connecting hole and the second connecting hole as arc-shaped long holes, the degree of freedom of the support 20 in movement can be increased, thereby avoiding interference between the cleaning brush module 10 and the roller brush cabin 30, etc. when the cleaning brush module 10 is raised.

[0061] In order to avoid the first roller brush 11 and the second roller brush 12 being installed in reverse, the first mounting shaft 22 and the second mounting shaft 23 have different structures. For example, the cross-sectional shapes of the first mounting shaft 22 and the second mounting shaft 23 are different; or the lengths of the first mounting shaft 22 and the second mounting shaft 23 are different; or the positioning structures on the surfaces of the first mounting shaft 22 and the second mounting shaft 23 are different. The positioning structure can be understood as a protruding part or a recessed part on the surface of the shaft body, etc. The positioning structures on the surfaces of the first mounting shaft 22 and the second mounting shaft 23 can be different in number or shape of the protruding parts or recessed parts thereon.

[0062] In the embodiments of the present disclosure, the side-by-side arrangement of the first roller brush 11 and the second roller brush 12 can be understood as that the first roller brush 11 and the second roller brush 12 are arranged in parallel, and the two ends of the first roller brush 11 and the second roller brush 12 are aligned. Or the first roller brush 11 and the second roller brush 12 are distributed approximately in a straight line.

[0063] The first roller brush 11 and the second roller brush 12 are located on the same side of the support 20. One end of the first roller brush 11 is connected to the support 20, and the other end of the first roller brush 11 is suspended. One end of the second roller brush 12 is connected to the support 20, and the other end of the second roller brush 12 is suspended. The end of the cleaning brush module 10 away from the support 20 is suspended, which facilitates the output of the garbage collected by the first roller brush 11 and the second roller brush 12 from the suspended end.

[0064] The first roller brush 11 comprises a first brush body 111 and a first brush strip 112, the first brush strip 112 is spirally arranged on the first brush body 111 to form the first cleaning element 110. For example, the first brush strip 112 is arranged on the surface of the first brush body 111 along a first spiral line. The first spiral line can extend from one end of the first brush body 111 to the other end of the first brush body 111.

[0065] The first brush body 111 can be in a cylindrical structure, and the first brush strip 112 is spirally arranged along the outer circumferential surface of the first brush body 111. A through hole or a blind hole can be arranged in the first brush body 111. The first connecting shaft is inserted into the hole of the first brush body 111.

[0066] The first brush strip 112 can be a rubber strip, for example, the first brush strip 112 is in a sheet structure, and the first brush strip 112 is made of rubber or silicone. The first brush strip 112 is in a rectangular or approximately rectangular structure in an unfolded state. The first brush strip 112 rolls the garbage on the operating surface (ground) into the cleaning brush module 10 when the first roller brush 11 rotates, and cooperates with the second roller brush 12 to transmit the garbage to the end away from the support 20.

[0067] The first brush strip 112 continuously extends on the surface of the first brush body 111. For example, the first brush strip 112 extends from one end of the first spiral line to the other end of the first spiral line, that is, the first brush strip 112 fills the first brush body 111 along the first spiral line.

[0068] It can be understood that the first roller brush 11 can also comprise a first bristle bundle 113, that is, the first cleaning element 110 comprises the first brush strip 112 and the first bristle bundle 113. The first brush strip 112 is arranged on part of the first spiral line, and the first bristle bundle 113 is arranged on part of the first spiral line. For example, the first bristle bundle 113 is located at the end of the first brush strip 112 away from the support 20. By combining the first brush strip 112 and the first bristle bundle 113, it can be avoided that the garbage is retained at the end of the first roller brush 11, and further prevent the garbage from winding the cleaning brush module 10.

[0069] The height of the first bristle bundle 113 is greater than the height of the first brush strip 112, the height of the first brush strip 112 is the distance from the end of the first brush strip 112 away from the first brush body 111 to the surface of the first brush body 111, and the height of the first bristle bundle 113 is the distance from the end of the first bristle bundle 113 away from the first brush body 111 to the surface of the first brush body 111. By setting the height of the first bristle bundle 113 arranged near the overhanging end to be greater than the height of the first brush strip 112, the contact area of the interaction between the first bristle bundle 113 and the second roller brush 12 at the overhanging end is increased, which is beneficial to the garbage transmission to the garbage channel at the overhanging end.

[0070] The distance between the end of the first brush strip 112 away from the first brush body 111 and the surface of the first brush body 111 refers to the distance between the end of the first brush strip 112 away from the first brush body 111 along the diameter direction of the first brush body 111. That is, a circle concentric with the first brush body 111 is drawn through the end of the first brush strip 112 away from the first brush body 111, and the difference between the radius of the circle and the radius of the first brush body 111 is the height of the first brush strip 112. The distance between the end of the first bristle bundle 113 away from the first brush body 111 and the surface of the first brush body 111 refers to the distance between the end of the first bristle bundle 113 away from the first brush body 111 along the diameter direction of the first brush body 111. That is, a circle concentric with the first brush body 111 is drawn through the end of the first bristle bundle 113 away from the first brush body 111, and the difference between the radius of the circle and the radius of the first brush body 111 is the height of the first bristle bundle 113.

[0071] In some embodiments, as shown in FIG. 5, the first roller brush 11 is provided with a plurality of first bristle bundles 113, and the plurality of first bristle bundles 113 are arranged on the side of the first brush strip 112 along the extension direction of the first brush strip 112. That is, the plurality of first bristle bundles 113 are arranged in parallel with the first brush strip 112 to form a row of the first roller brush 11.

[0072] The distance between the bottom end of the first bristle bundle 113 and the support 20 is less than the distance between the top end of the first bristle bundle 113 and the support 20. The bottom end of the first bristle bundle 113 is the end connected to the first brush body 111, and the top end of the first bristle bundle 113 is the end away from the first brush body 111. That is, the first bristle bundle 113 is inclined to the free end of the cleaning brush module 10, and the first bristle bundle 113 is inclined to the free end of the cleaning brush module 10, which facilitates the transmission of garbage by the first bristle bundle 113 to the free end.

[0073] The second roller brush 12 includes a second brush body 121 and a plurality of second bristle bundles 122, and the plurality of second bristle bundles 122 are arranged in a spiral on the second brush body 121 to form a second cleaning element 120. For example, the plurality of second roller brushes 12 can be arranged along a second spiral line on the second brush body 121, and the pitch of the second spiral line can be the same as the pitch of the first spiral line.

[0074] The second brush body 121 can have a cylindrical structure, and the second bristle bundle 122 is arranged in a spiral along the outer circumferential surface of the second brush body 121. A through hole or a blind hole can be arranged in the second brush body 121, and the second connecting shaft is inserted into the hole of the first brush body 111.

[0075] Alternatively, the second roller brush 12 includes a second brush body 121, a second brush strip 123, and a plurality of second bristle bundles 122, and the second brush strip 123 and the plurality of second bristle bundles 122 are arranged in a spiral on the second brush body 121 to form a second cleaning element 120.

[0076] The second bristle tufts 122 are discretely distributed on the second brush body 121, that is, there is a spacing between any two adjacent second bristle tufts 122 among the plurality of second bristle tufts 122. The second bristle tufts 122 include a plurality of bristles, and the hardness of the bristles is greater than the hardness of the first brush strips 112. The second bristle tufts 122 push the garbage wrapped on the first brush strips 112 towards the free end of the cleaning brush module 10.

[0077] In some embodiments, as shown in FIG. 6, the second roller brush 12 is provided with a plurality of second brush strips 123, and the second brush strips 123 are arranged on the side of the second bristle tufts 122. That is, the plurality of second bristle tufts 122 are arranged in parallel with the second brush strips 123.

[0078] The second brush strips 123 continuously extend on the surface of the second brush body 121. For example, the second brush strips 123 extend from one end of the second spiral line to the other end of the second spiral line, that is, the second brush strips 123 are arranged on the second brush body 121 along the second spiral line.

[0079] The second bristle tufts 122 are inclined towards the free end of the second roller brush 12. That is, the distance from the bottom end of the second bristle tufts 122 to the support 20 is less than the distance from the top end of the second bristle tufts 122 to the support 20. The bottom end of the second bristle tufts 122 is the end connected to the second brush body 121, and the top end of the second bristle tufts 122 is the end away from the second brush body 121. That is, the second bristle tufts 122 are inclined towards the free end of the cleaning brush module 10. By inclining the second bristle tufts 122 towards the free end of the cleaning brush module 10, it is convenient for the second bristle tufts 122 to transmit the garbage to the free end.

[0080] In the roller brush assembly provided in the embodiments of the present disclosure, the first roller brush 11 can be a rubber brush (provided with the first brush strips 112), the second roller brush 12 can be a bristle brush (provided with the second bristle tufts 122); or the first roller brush 11 can be a rubber-bristle integrated brush (provided with the first brush strips 112 and the first bristle tufts 113), the second roller brush 12 can be a bristle brush (provided with the second bristle tufts 122); or the first roller brush 11 can be a rubber-bristle integrated brush (provided with the first brush strips 112 and the first bristle tufts 113), or the second roller brush 12 can be a rubber-bristle integrated brush (provided with the second brush strips 123 and the second bristle tufts 122). Or the first roller brush 11 can be a rubber brush (provided with the first brush strips 112), and the second roller brush 12 can be a rubber-bristle integrated brush (provided with the second brush strips 123 and the second bristle tufts 122).

[0081] The first and second rolling brushes 11 and 12 are configured to sweep the dirt to the end of the cleaning brush module 10 away from the support 20 when the first and second brush bodies 111 and 121 rotate. For example, the first brush strips 112 and the second bristle bundles 122 are configured to sweep the dirt to the end of the cleaning brush module 10 away from the support 20 when the first and second brush bodies 111 and 121 rotate.

[0082] During the working process of the first and second rolling brushes 11 and 12, the first and second cleaning elements 110 and 120 interfere with each other. Thus, the first and second rolling brushes 11 and 12 interact with each other during the working process, so as to strip the dirt from the rolling brushes. Of course, in some embodiments, the first and second cleaning elements 110 and 120 can not interfere with each other during the working process of the first and second rolling brushes 11 and 12.

[0083] In some embodiments, at least one of the first brush strips 112 and the second bristle bundles 122 is a flexible structure; the sum of the height of the second bristle bundles 122 and the height of the first brush strips 112 is greater than or equal to the distance between the first and second brush bodies 111 and 121, so that the first brush strips 112 and the second bristle bundles 122 at least partially contact each other when the first and second brush bodies 111 and 121 rotate. The height of the first brush strips 112 is the distance between the end of the first brush strips 112 away from the first brush body 111 and the surface of the first brush body 111. The height of the second bristle bundles 122 is the distance between the end of the second bristle bundles 122 away from the second brush body 121 and the surface of the second brush body 121. That is, the first and second rolling brushes 11 and 12 at least partially contact each other during the working process, so that the first and second rolling brushes 11 and 12 can interact with each other to transfer the dirt to the free end.
