[0062] As Figure 1 shown, in the cleaning module of the related art, the roller brush 300' is always arranged in the roller brush bin 100', and then the roller brush 300' is fixed by the roller brush cover 200' to prevent the roller brush 300' from falling off. The cleaning module of this structure is not convenient for replacing the roller brush. When replacing the roller brush 300', it is necessary to first disassemble the roller brush cover 200', and then the roller brush 300' can be taken out. Moreover, both ends of the roller brush 300' are connected to the roller brush bin 100', which also brings inconvenience to the replacement of the roller brush bin 100'.

[0063] Based on this, the present utility model provides a roller brush cover, which includes: a housing; a roller brush support frame disposed at one end of the housing, and the roller brush support frame is configured to cooperate with the assembly end of the roller brush. The roller brush cover provided by the present utility model enables the roller brush to be detachably disposed on the roller brush cover and form an integrally installable structure, so that the roller brush and the roller brush cover can be integrally assembled into the roller brush bin or integrally detached from the roller brush bin. When the roller brush needs to be replaced, only the cleaning brush head needs to be integrally detached and replaced, which is more convenient for disassembly and assembly. In addition, one end of the cleaning roller brush provided by the present utility model is the driving end, and the other end is the free end, so that the object to be cleaned is more likely to move from the driving end to the free end until it is sucked away, and is not easily wound around the roller brush.

[0064] The following will describe in detail the optional embodiments of the present disclosure with reference to the accompanying drawings.

[0065] As Figure 2 、 Figure 3 shown, this embodiment provides a roller brush cover 200, which includes a housing 240 and a roller brush support frame 210. The roller brush support frame 210 is disposed at one end of the housing 240. The roller brush cover 200 is used for assembling a roller brush 300. The roller brush 300 has an assembly end 320, a free end 330, and a brush member 340. The roller brush support frame 210 is configured to cooperate with the assembly end 320 of the roller brush 300. The roller brush cover 200 and the roller brush 300 form a structure that can be independently detached and installed from the cleaning device, thereby facilitating the user to replace the roller brush. Optionally, the housing 240 includes an avoidance portion 260, and the avoidance portion 260 is disposed at one end of the housing 240 away from the roller brush support frame 210. The avoidance portion 260 is configured to avoid the free end 330 of the roller brush 300.

[0066] In some embodiments, as Figure 2 、 Figure 3 shown, the roller brush support frame 210 includes an end cap 212, and the end cap 212 is substantially perpendicular to the axis of the roller brush 300. The end cap 212 is configured to abut against the assembly end 320 of the roller brush 300 and accommodate the assembly end 320 of the roller brush 300; the end cap 212 has a portion extending along the axis of the roller brush 300 to the edge portion, which is used to better support the roller brush 300. The roller brush support frame 210 further includes a connecting rod 211, and the connecting rod 211 extends substantially perpendicular to the end cap 212 along the axis. The connecting rod 211 is configured to be connected to the assembly end 320 of the roller brush 300. The connecting rod 211 is a hollow structure, which is convenient for the driving structure 500 to pass through and drive the roller brush to rotate.

[0067] In some embodiments, as Figure 3 、 Figure 4As shown, the end cap 212 includes a stepped portion 2121 which is disposed around the root of the connecting rod 211. The stepped portion 2121 is configured to abut against the assembly end 320 of the roller brush 300. The stepped portion 2121 is generally formed with a structure having different heights along the axial direction to be stably connected after fitting the assembly end 320 of the roller brush 300.

[0068] In some embodiments, as Figure 3 , Figure 4 shown, the roller brush support frame 210 further includes a clamping member 2122 which is disposed at the edge of the end cap 212. The clamping member 2122 is configured to elastically clamp the assembly end 320 of the roller brush 300. The clamping member 2122 is, for example, a tongue member with a free end or other elastic members. There is a gap between the clamping member 2122 and the edge of the end cap 212 to have a certain elasticity in the radial direction. When the roller brush 300 is assembled to the end cap 212, the clamping member 2122 expands radially outward after being squeezed. After the roller brush 300 is assembled to the end cap 212, the clamping member 2122 rebounds and clamps the assembly end 320 of the roller brush 300. Optionally, the side of the clamping member 2122 facing the roller brush 300 has a clamping protrusion 2123 which is configured to further clamp the assembly end 320 of the roller brush 300.

[0069] In some embodiments, as Figure 4 shown, the roller brush cover 200 further includes a limiting protrusion 220 which is disposed on the side of the housing 240 close to the assembly end 320 of the roller brush. The limiting protrusion 220 is configured to be in limiting clamping connection with the roller brush bin 100.

[0070] In some embodiments, as Figure 4 shown, the roller brush cover 200 further includes a limiting rib 250 which is axially extended and disposed on at least one side wall end face of the housing 240. When the roller brush cover 200 is assembled to the roller brush bin 100, the limiting rib 250 is clamped with the groove on the roller brush bin 100.

[0071] In some embodiments, as Figure 5 shown, the roller brush support frame 210 further includes at least one support portion 2124 which protrudes from the outer surface of the end cap 212 and extends in a direction away from the roller brush 300. The support portion 2124 is configured to assist in supporting the roller brush cover 200 when the roller brush cover 200 is assembled to the roller brush bin 100.

[0072] The embodiments of the present disclosure provide a cleaning module, as Figure 6As shown, the cleaning module is used to clean the object to be cleaned on the cleaning surface. The cleaning module includes a roller brush bin 100, a cleaning brush head 600, and a gearbox 400. The roller brush bin 100 is connected to the gearbox 400, and the output shaft of the gearbox 400 extends into the roller brush bin 100 to provide driving force for the cleaning brush head 600.

[0073] As Figure 7 shown, the cleaning brush head 600 includes a roller brush cover 200 and a roller brush 300, and the cleaning brush head 600 is detachably connected to the roller brush bin 100. The structures of the roller brush cover 200 and the roller brush 300 refer to the above embodiments and will not be elaborated here. Through the above structure, it can be understood that for the cleaning brush head 600 provided by the present utility model, since the roller brush 300 and the roller brush cover 200 are in a stable connection structure, and the roller brush cover 200 and the roller brush bin 100 are also in a stable connection structure, the roller brush 300 is not easily detached from the roller brush bin 100 during the rotation and use process. In addition, when the roller brush needs to be replaced, the roller brush can be directly detached together by detaching the cleaning brush head, instead of first detaching the roller brush cover and then the roller brush, which saves the disassembly procedure and facilitates the replacement of the roller brush.

[0074] As Figure 8 shown, the roller brush bin 100 has a driving end 110 and a non-driving end 120; between the driving end 110 and the non-driving end 120 of the roller brush bin 100 is a receiving space 130, which is configured to at least receive the roller brush 300, for example, 1-4 roller brushes can be received. When multiple roller brushes are received, they can be arranged side by side, and no limitation is made thereto. In some embodiments, the roller brush bin 100 includes a dust suction port 140, and the dust suction port 140 is provided on one side of the non-driving end 120 of the roller brush bin 100. When the object to be cleaned moves axially along the roller brush 300 to near the non-driving end 120 of the roller brush bin 100, it is sucked into the dust collection device by the dust suction port 140, improving the cleaning efficiency.

[0075] Specifically, as Figure 8 shown, in some embodiments, the roller brush bin 100 has an axially extending receiving space 130, and multiple roller brushes 300 can be received in the receiving space 130. When the roller brush 300 is assembled in the receiving space 130 to perform the cleaning task, the roller brush 300 generally does not interfere with the inner wall of the receiving space 130, so as not to affect the rotation speed of the roller brush and generate slapping noises, etc. The non-driving end 120 of the roller brush bin 100 is a semi-surrounding structure, which can receive the free end of the roller brush 300 and can also prevent dust or garbage from overflowing from the non-driving end 120 of the roller brush bin 100 to contaminate the cleaning surface.

[0076] In some embodiments, as Figure 8As shown, one side of the roller brush bin 100 close to the drive end 110 has a limit groove 150, and the depth of the limit groove 150 is deeper at the position closer to the drive end 110, which is convenient for the inclined insertion of the cleaner 600. There is a groove 170 on the end face of the side wall of the roller brush bin 100, and the groove 170 is snap-connected with the limit rib 250 on the roller brush cover.

[0077] In some embodiments, referring to Figure 8 , the roller brush bin 100 further includes a locking member 160, which is arranged on the side close to the non-drive end 120. When one end of the cleaning brush head 600 is first inserted into the roller brush bin 100, after rotation, the free end 330 of the roller brush 300 enters the roller brush bin 100, and then the locking member 160 of the roller brush bin 100 is cooperated with the locking part 230 of the roller brush cover 200 to achieve locking.

[0078] In some embodiments, as Figure 9 - Figure 10 shown, in the cleaning brush head 600, one side of the roller brush cover 200 has a roller brush support frame 210, and the number of the roller brush support frames 210 corresponds to that of the roller brushes 300, which is used to support the roller brushes 300. The roller brush support frame 210 includes an axially extending connecting rod 211. One end of the roller brush 300 has an axially extending recess 310, and the connecting rod 211 is inserted into the recess 310 so that the roller brush 300 is arranged on the roller brush cover 200.

[0079] In some embodiments, as Figure 9 shown, the cleaning brush head 600 further includes a driving structure 500, which is used to drive the roller brush 300 to rotate. The driving structure 500 is axially connected to the hollow connecting rod 211 and the roller brush 300 along the axis of the roller brush, so that the driving structure 500, the roller brush cover 200 and the roller brush 300 form a stable connection structure.

[0080] In some embodiments, as Figure 9 shown, the driving structure 500 includes a driving shaft 510 extending axially. The driving shaft 510 axially passes through the connecting rod 211 and then is connected to the roller brush 300. As Figure 10 shown, the end of the driving shaft 510 inserted into the roller brush 300 has a fastening structure 512, and the fastening structure 512 is configured to be tightly connected with the groove of the roller brush 300. The setting of the fastening structure 512 can make the roller brush 300 not easily fall off the roller brush cover 200 axially. In addition, it can also make the roller brush rotate stably under the drive of the driving structure 500. The fastening structure 512 is, for example, a spiral structure. In some embodiments, the end of the driving shaft 510 away from the roller brush has a keying structure 511, and the keying structure 511 is configured to be connected to the drive end 110 of the roller brush bin 100. The keying structure 511 is set as a polygonal or plum-shaped structure, etc. Correspondingly, asFigure 11 As shown, the end of the output shaft of the gearbox 400 has a clamping recess 410, which is also in a polygonal or plum shape structure, etc. The outer contour of the clamping recess 410 matches the outer contour of the bonding structure 511, so that the bonding structure 511 can be stably connected to the clamping recess 410 and rotate under the drive of the output shaft of the gearbox 400. In some embodiments, as Figure 11 shown, the outer edge of the clamping recess 410 has an inclined surface 411 away from the center, and the size of the outer contour of the inclined surface 411 is larger than the size of the inner aperture of the clamping recess 410. Such a setting facilitates the installation of the bonding structure 511. When the overall structure of the roller brush cover 200 and the roller brush 300 is assembled into the roller brush bin 100, the overall structure of the roller brush cover 200 and the roller brush 300 needs to be inserted into the roller brush bin 100 obliquely first, and then inserted horizontally along the axis into the clamping recess 410. During the oblique insertion process, the bonding structure 511 first contacts the inclined surface 411, and the larger outer contour size of the inclined surface 411 gives the bonding structure 511 a larger redundant space, so that the overall structure of the roller brush cover 200 and the roller brush 300 can be smoothly inserted into the clamping recess 410, thus connecting with the output shaft of the gearbox 400.

[0081] The roller brush provided by the present disclosure is arranged on the roller brush cover to form an integral detachable cleaning brush head. The roller brush and the roller brush cover can be integrally assembled into the roller brush bin or integrally disassembled from the roller brush bin, making the disassembly and assembly of the roller brush more convenient and the roller brush not easily falling off from the roller brush bin.

[0082] The embodiments of the present disclosure also provide a cleaning device, including the cleaning module described in any one of the above embodiments. After the cleaning module is assembled into the cleaning device, it performs a cleaning task. The cleaning device described in the present disclosure, such as a self-propelled robot, a mopping robot, a vacuum cleaner, a floor washer, a weeding machine, etc., is not limited thereto, and any cleaning robot that can assemble the cleaning brush head described in the present disclosure can be implemented.

[0083] For the specific structures, working principles, and beneficial effects of the cleaning brush head, cleaning module, and cleaning device provided by the embodiments of the present disclosure, reference can be made to the cleaning brush head and cleaning device described in any of the above embodiments, and details are not described herein again.

[0084] Finally, it should be noted that the embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the system or device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
