[0053] The exemplary embodiment of the present disclosure first provides a rotating brush assembly 100, as Figure 1 andFigure 2 As shown, the roller brush assembly 100 includes at least a first roller brush 11 and a second roller brush 12, and the first roller brush 11 and the second roller brush 12 are placed side by side; one end of the first roller brush 11 is driven by a driving device, and the other end is a free end; one end of the second roller brush 12 is driven by a driving device, and the other end is a free end; a first cleaning member 110 is provided on the first roller brush 11, and a second cleaning member 120 is provided on the second roller brush 12, and the first cleaning member 110 is different from the second cleaning member 120.

[0054] The roller brush assembly provided by the embodiment of the present disclosure includes a first roller brush 11 and a second roller brush 12. One end of the first roller brush 11 is driven by a driving device, and the other end is a free end. One end of the second roller brush 12 is driven by a driving device, and the other end is a free end. A first cleaning member 110 is provided on the first roller brush 11, and a second cleaning member 120 is provided on the second roller brush 12. The first cleaning member 110 is different from the second cleaning member 120. By setting the ends of the first roller brush 11 and the second roller brush 12 that are away from the driving device as free ends, garbage on the first roller brush 11 and the second roller brush 12 can fall off from the free ends through interaction during operation, thereby preventing garbage from being entangled with the first roller brush 11 and the second roller brush 12.

[0055] Furthermore, the roller brush assembly 100 provided in the embodiment of the present disclosure further includes a roller brush compartment 30 and a bracket 20. The roller brush compartment 30 is provided with an opening installation space, and there is a gap between the free ends of the first roller brush 11 and the second roller brush 12 and the roller brush compartment wall. The bracket 20 is provided in the roller brush compartment 30, and the first roller brush 11 and the second roller brush 12 are connected to the bracket 20. The bracket 20 has at least a first posture and a second posture. When the bracket 20 is in the first posture, the first roller brush 11 and the second roller brush 12 are located in the roller brush compartment 30. When the bracket is in the second posture, the free ends of the first roller brush 11 and the second roller brush 12 are tilted.

[0056] The various parts of the roller brush assembly 100 provided in the embodiment of the present disclosure are described in detail below:

[0057] The bracket 20 is used to install the first brush body 111 and the second brush body 121. Figure 3 As shown, the bracket 20 may include 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 axially disposed in the frame body 21, and the first mounting shaft 22 and the second mounting shaft 23 are rotatable relative to the frame body 21. The first mounting shaft 22 and the second mounting shaft 23 are arranged in parallel, the first roller brush 11 is mounted on the first mounting shaft 22, and the second roller brush 12 is mounted on the second mounting shaft 23.

[0058] The bracket 20 has at least a first posture and a second posture. When the bracket 20 is in the first posture, the first roller brush 11 and the second roller brush 12 are located in the roller brush compartment 30, and the first mounting shaft 22 and the second mounting shaft 23 are in a horizontal state. As Figure 4 shown, when the bracket 20 is in the second posture, the free ends of the first roller brush 11 and the second roller brush 12 are tilted up. At this time, it is convenient for the user to remove the first roller brush 11 and the second roller brush 12.

[0059] Exemplarily, a first connecting ear and a second connecting ear are provided on the bracket 20. The first connecting ear and the second connecting ear are arranged oppositely, and there is a gap between the first connecting ear and the second connecting ear. The roller brush compartment 30 has a connecting portion located between the first connecting ear and the second connecting ear. A first connecting shaft and a second connecting shaft are provided on the connecting portion. A first connecting hole is provided on the first connecting ear, and the first connecting shaft passes through the first connecting hole and can rotate in the first connecting hole. A second connecting hole is provided on the second connecting ear, and the second connecting shaft passes through 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. Setting the first connecting hole and the second connecting hole as arc-shaped long holes can increase the degree of freedom of movement of the bracket 20, thereby avoiding interference with the roller brush compartment 30 and the like when the cleaning brush module 10 is lifted.

[0061] In order to avoid the first roller brush 11 and the second roller brush 12 being installed in the wrong direction during installation, the structures of the first mounting shaft 22 and the second mounting shaft 23 are different. 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, etc. The positioning structure can be understood as a convex portion or a concave portion 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 are different, which can be that the number or shape of the convex portions or concave portions on them is different.

[0062] In the embodiments of the present disclosure, the first roller brush 11 and the second roller brush 12 being placed side by side can be understood as: 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 rotatable brush 11 and the second rotatable brush 12 are located on the same side of the bracket 20. One end of the first rotatable brush 11 is connected to the bracket 20, and the other end of the first rotatable brush 11 is suspended. One end of the second rotatable brush 12 is connected to the bracket 20, and the other end of the second rotatable brush 12 is suspended. One end of the cleaning brush module 10 facing away from the bracket 20 is suspended, facilitating the output of the garbage collected by the first rotatable brush 11 and the second rotatable brush 12 from the suspended end.

[0064] The first rotatable brush 11 includes 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 a first cleaning member 110. For example, the first brush strip 112 is arranged on the surface of the first brush body 111 along a first spiral. The first spiral can spirally extend from one end of the first brush body 111 to the other end of the first brush body 111.

[0065] Among them, 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. Through holes or blind holes 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 thin sheet structure and is made of materials such as rubber or silica gel. The first brush strip 112 is in a rectangular or approximately rectangular structure in the unfolded state. When the first rotatable brush 11 rotates, the first brush strip 112 rolls the garbage on the operation surface (ground) into the cleaning brush module 10 and cooperates with the second rotatable brush 12 to transport the garbage to one end away from the bracket 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 to the other end of the first spiral, that is, the first brush strip 112 covers the first brush body 111 along the first spiral.

[0068] It can be understood that the first rotatable brush 11 can further include a first brush hair bundle 113, that is, the first cleaning member 110 includes the first brush strip 112 and the first brush hair bundle 113. The first brush strip 112 is arranged in some areas on the first spiral, and the first brush hair bundle 113 is arranged in some areas. For example, the first brush hair bundle 113 is located at the end of the first brush strip 112 facing away from the bracket 20. By combining the first brush strip 112 and the first brush hair bundle 113, it is possible to prevent garbage from staying at the end of the first rotatable brush 11 and further prevent the garbage from winding around 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 between the end of the first brush strip 112 facing away from the first brush body 111 and the surface of the first brush body 111. The height of the first bristle bundle 113 is the distance between the end of the first bristle bundle 113 facing away from the first brush body 111 and the surface of the first brush body 111. By setting the height of the first bristle bundle 113 disposed near the free 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 free end is increased, which is beneficial to transporting the garbage to the garbage passage at the free end.

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

[0071] In some embodiments, as Figure 5 shown, a plurality of first bristle bundles 113 are provided on the first roller brush 11, and the plurality of first bristle bundles 113 are disposed on the side of the first brush strip 112 and arranged along the extending direction of the first brush strip 112. That is to say, the plurality of first bristle bundles 113 form a first roller brush 11 hair row and are arranged side by side with the first brush strip 112.

[0072] The distance from the bottom end of the first bristle bundle 113 to the bracket 20 is less than the distance from the top end of the first bristle bundle 113 to the bracket 20. The bottom end of the first bristle bundle 113 is the end where the first bristle bundle 113 is connected to the first brush body 111, and the top end of the first bristle bundle 113 is the end of the first bristle bundle 113 facing away from the first brush body 111. That is to say, the first bristle bundle 113 inclines towards the free end of the cleaning brush module 10. By inclining the first bristle bundle 113 towards the free end of the cleaning brush module 10, it is convenient for the first bristle bundle 113 to transport the garbage towards the free end.

[0073] The second rotary brush 12 includes a second brush body 121 and a plurality of second brush tufts 122. The plurality of second brush tufts 122 are spirally arranged on the second brush body 121 to form a second cleaning member 120. For example, the plurality of second rotary brush hairs 12 can be distributed along a second spiral on the second brush body 121, and the pitch of the second spiral can be the same as the pitch of the first spiral.

[0074] Among them, the second brush body 121 can be in a cylindrical structure, and the second brush tufts 122 are spirally arranged along the outer circumferential surface of the second brush body 121. A through hole or a blind hole can be provided 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 rotary brush 12 includes a second brush body 121, a second brush strip 123, and a plurality of second brush tufts 122. The second brush strip 123 and the plurality of second brush tufts 122 are spirally arranged on the second brush body 121 to form a second cleaning member 120.

[0076] The second brush tufts 122 are discretely distributed on the second brush body 121. That is, there is a gap between two adjacent second brush tufts 122 among the plurality of second brush tufts 122. The second brush tufts 122 include a plurality of bristles, and the hardness of the bristles is greater than the hardness of the first brush strip 112. The garbage wound around the first brush strip 112 is pushed towards the free end of the cleaning brush module 10 by the second brush tufts 122.

[0077] In some embodiments, as Figure 6 shown, a plurality of second brush strips 123 are provided on the second rotary brush 12, and the second brush strips 123 are arranged on the side of the second brush tufts 122. That is, the plurality of second brush tufts 122 and the second brush strips 123 are arranged side by side to form the second rotary brush hair rows.

[0078] The second brush strips 123 continuously extend on the surface of the second brush body 121. For example, the second brush strip 123 extends from one end of the second spiral to the other end of the second spiral. That is, the second brush strip 123 covers the second brush body 121 along the second spiral.

[0079] The second brush tufts 122 are inclined towards the free end of the second rotary brush 12. That is, the distance from the bottom end of the second brush tuft 122 to the bracket 20 is less than the distance from the top end of the second brush tuft 122 to the bracket 20. The bottom end of the second brush tuft 122 is the end where the second brush tuft 122 is connected to the second brush body 121, and the top end of the second brush tuft 122 is the end where the second brush tuft 122 deviates from the second brush body 121. That is, the second brush tufts 122 are inclined towards the free end of the cleaning brush module 10. By inclining the second brush tufts 122 towards the free end of the cleaning brush module 10, it is convenient for the second brush tufts 122 to transfer the garbage towards the free end.

[0080] In the brush roller assembly provided by the embodiments of the present disclosure, the first brush roller 11 may be a rubber brush (with a first brush strip 112 provided thereon), and the second brush roller 12 may be a hair brush (with a second hair bundle 122 provided thereon); or the first brush roller 11 may be a rubber-hair integrated brush (with a first brush strip 112 and a first hair bundle 113 provided thereon), and the second brush roller 12 may be a hair brush (with a second hair bundle 122 provided thereon); or the first brush roller 11 may be a rubber-hair integrated brush (with a first brush strip 112 and a first hair bundle 113 provided thereon), or the second brush roller 12 may be a rubber-hair integrated brush (with a second brush strip 123 and a second hair bundle 122 provided thereon). Or the first brush roller 11 may be a rubber brush (with a first brush strip 112 provided thereon), and the second brush roller 12 may be a rubber-hair integrated brush (with a second brush strip 123 and a second hair bundle 122 provided thereon).

[0081] The first brush roller 11 and the second brush roller 12 are configured to be able to sweep the object to be cleaned to one end of the cleaning brush module 10 away from the bracket 20 when the first brush body 111 and the second brush body 121 rotate. For example, the first brush strip 112 and the second hair bundle 122 are configured to be able to sweep the object to be cleaned to one end of the cleaning brush module 10 away from the bracket 20 when the first brush body 111 and the second brush body 121 rotate.

[0082] During the working process of the first brush roller 11 and the second brush roller 12, interference occurs between the first cleaning member 110 and the second cleaning member 120. As a result, there is an interaction between the first brush roller 11 and the second brush roller 12 during work, so as to peel the garbage from the brush roller. Of course, in some embodiments, during the working process of the first brush roller 11 and the second brush roller 12, interference may not occur between the first cleaning member 110 and the second cleaning member 120.

[0083] Wherein, at least one of the first brush strip 112 and the second hair bundle 122 is a flexible structure; the sum of the height of the second hair bundle 122 and the height of the first brush strip 112 is greater than or equal to the distance between the first brush body 111 and the second brush body 121, so that when the first brush body 111 and the second brush body 121 rotate, the first brush strip 112 and the second hair bundle 122 are at least partially in contact. The height of the first brush strip 112 is 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, and the height of the second hair bundle 122 is the distance between the end of the second hair bundle 122 away from the second brush body 121 and the surface of the second brush body 121. That is to say, during work, the first brush roller 11 and the second brush roller 12 are at least partially in contact, so that the first brush roller 11 and the second brush roller 12 can interact with each other to transfer the garbage to the free end.

[0084] It should be noted that the distance between the end of the first brush strip 112 departing from the first brush body 111 and the surface of the first brush body 111 refers to the distance along the diameter direction of the first brush body 111 at the end of the first brush strip 112 departing from the first brush body 111. That is to say, a circle concentric with the first brush body 111 is made through the end of the first brush strip 112 departing from the first brush body 111, and the difference between the radius of this 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 second brush bundle 122 departing from the second brush body 121 and the surface of the second brush body 121 refers to the distance along the diameter direction of the second brush body 121 at the end of the second brush bundle 122 departing from the second brush body 121. That is to say, a circle concentric with the second brush body 121 is made through the end of the second brush bundle 122 departing from the second brush body 121, and the difference between the radius of this circle and the radius of the second brush body 121 is the height of the second brush bundle 122. The distance between the first brush body 111 and the second brush body 121 is the distance between the surface of the first brush body 111 and the surface of the second brush body 121. For example, the distance between the first brush body 111 and the second brush body 121 is the minimum distance between two cylindrical surfaces (the cylindrical surface formed by the first spiral line and the cylindrical surface formed by the second spiral line).

[0085] The first rotary brush 11 and the second rotary brush 121 are arranged in parallel, and the first brush body 111 and the second brush body 121 are arranged in parallel, ensuring that the transmission space remains unchanged during the garbage cleaning and transmission process, and avoiding the entanglement of garbage and cleaning brushes caused by the sudden change of the transmission space.

[0086] It should be noted that in the embodiments of the present disclosure, the first brush body 111 and the second brush body 121 being parallel actually means that the first brush body 111 and the second brush body 121 are approximately parallel. That is to say, within the allowable error range, the first brush body 111 and the second brush body 121 are parallel. For example, if the included angle between the axis of the first brush body 111 and the axis of the second brush body 121 is less than a preset angle, it is considered that the first brush body 111 and the second brush body 121 are parallel. The preset angle can be 3 degrees, 5 degrees or 10 degrees, etc.

[0087] The first brush strip 112 is arranged on the first brush body 111 along the first spiral line, and a plurality of second brush bundles 122 are arranged on the second brush body 121 along the second spiral line. The spiral directions of the first spiral line and the second spiral line are opposite. That is to say, the spiral directions of the components for cleaning on the first rotary brush 11 and the second rotary brush 12 are opposite, and the opposite spiral directions can transfer the garbage to the same end.

[0088] The driving device drives the first brush body 111 and the second brush body 121 to rotate respectively, and the rotation directions of the first brush body 111 and the second brush body 121 are opposite. The driving device drives the first brush body 111 and the second brush body 121 to rotate in opposite directions, and cooperates with the spiral structures on the first brush body 111 and the second brush body 121 to realize the transfer of garbage to the suspended end. Among them, the first rotary brush 11 and the second rotary brush 12 rotate synchronously or at different speeds.

[0089] The driving device may include a driving motor and a transmission box, the transmission box includes an input shaft, a first output shaft, a second output shaft and a gear set, the input shaft is connected to the driving motor, the first output shaft is connected to the first mounting shaft on the bracket 20, and the second output shaft is connected to the second mounting shaft on the bracket 20. The gear set transmits the power output by the driving motor to the first output shaft and the second output shaft, and causes the first output shaft and the second output shaft to rotate in opposite directions.

[0090] The roller brush chamber 30 is provided with an opening installation space, the bracket 20 is installed at one end of the installation space, and a gap 31 is formed between the cleaning brush module 10 and the side wall of the roller brush chamber 30 which is away from the bracket 20 .

[0091] An interface portion 40 is provided at the bottom of the roller brush compartment 30, and the interface portion 40 is connected to the partition 31. The bottom of the roller brush compartment 30 is an end of the roller brush compartment 30 away from the installation space opening. The interface portion 40 is used to connect to the trash can of the cleaning equipment.

[0092] For example, the roller brush compartment 30 may be provided with a first sub-installation space and a second sub-installation space, the first roller brush 11 is located in the first sub-installation space, and the second roller brush 12 is located in the second sub-installation space. The first sub-installation space is a curved concave portion, and the second sub-installation space is a curved concave portion.

[0093] The bracket 20 is arranged at one end of the installation space, and the side wall of the installation space away from the bracket 20 is opposite to the end of the roller brush, and there is a gap of a preset distance between the side wall and the end of the roller brush, so that the end of the roller brush away from the bracket 20 is suspended in the air. When the garbage cleaned by the roller brush is transmitted to the suspended end along the spirally arranged brush bar and the bristle bundle back, the garbage falls into the interface part 40 from the gap between the cleaning module and the side wall of the installation space. The interface part 40 is connected to a fan and a garbage bin, and the garbage is sucked into the garbage bin by the fan.
