[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a cleaning module, including a cleaning brush 1 and a driving member, the cleaning brush 1 is provided with a mounting hole 11, and the cleaning brush 1 is connected and fixed through the mounting hole 11. The driving member is used to drive the cleaning brush 1 to perform a cleaning action.

[0038] Specifically, the cleaning brush 1 can be various types of brushes such as a side brush or a disc brush, and is applied to cleaning equipment such as a cleaning robot and a floor scrubber. The cleaning action performed by the cleaning brush 1 can be rotational cleaning or vibration cleaning. Correspondingly, the driving member can be a motor or an eccentric motor, or a combination of a motor or an eccentric motor and a transmission mechanism such as a gearbox. Here, there is no restriction on the specific structural form of the cleaning brush 1 and the driving member.

[0039] In this embodiment, the driving member is described by taking the motor 2 as an example. The cleaning brush 1 is driven and connected to the motor 2, and the cleaning brush 1 is driven to rotate by the motor 2 to achieve the cleaning function. Of course, in other embodiments, a transmission structure such as a gearbox can also be connected between the motor 2 and the cleaning brush 1. In this case, the motor 2 is driven and connected to the input shaft of the gearbox, and the cleaning brush 1 is driven and connected to the output shaft of the gearbox.

[0040] In order to facilitate the disassembly and maintenance of the cleaning brush 1, Figure 3 and Figure 4 As shown, this embodiment further provides a brush connector 3, which is used to connect the cleaning brush 1 to the output shaft 21 of the motor 2. Specifically, the brush connector 3 includes a support assembly 31, a limiter 32 and an adjustment assembly 33. The support assembly 31 is connected to the output shaft 21 of the motor 2. The support assembly 31 can be inserted into the mounting hole 11 and limit the rotation of the cleaning brush 1 relative to the support assembly 31. The limiter 32 is movably arranged on the support assembly 31. When the limiter 32 moves to protrude from the support assembly 31, it can limit the cleaning brush 1 from sliding along the support assembly 31. The adjustment assembly 33 is arranged in the support assembly 31. The adjustment assembly 33 can adjust and lock the limiter 32 so that the limiter 32 protrudes from the outer surface of the support assembly 31 or retracts into the outer surface of the support assembly 31.

[0041] The cleaning module provided in this embodiment is connected to the driving member by setting a brush connector 3. During assembly, the cleaning brush 1 is placed on the support assembly 31, and the cleaning brush 1 is limited to slide along the support assembly 31 by setting a limiter 32, so that the cleaning brush 1 is fixed to the support assembly 31 to prevent the cleaning brush 1 from detaching from the support assembly 31. The support assembly 31 is connected to the output shaft 21 of the driving assembly, so as to realize the driving connection between the cleaning brush 1 and the output shaft 21. The setting adjustment assembly 33 can adjust the limiter 32 so that the limiter 32 moves to the position of limiting or releasing the limit of the cleaning brush 1, so as to realize the flexible disassembly and assembly of the cleaning brush 1. After the limiter 32 moves to the position of limiting the cleaning brush 1, the limiter 32 is locked by the adjustment assembly 33 to ensure the reliability of the limiter 32 limiting the cleaning brush 1, so that the cleaning brush 1 is firmly installed to prevent the cleaning brush 1 from falling off.

[0042] like Figure 3 and Figure 4 As shown, the support assembly 31 includes an end plate 311 and a support housing 312. The end plate 311 is provided with a connection hole 31101. The output shaft 21 is connected to the connection hole 31101. The output shaft 21 of the driving member is connected to the support assembly 31 through the connection hole 31101. The support housing 312 is detachably connected to the side of the end plate 311 away from the motor 2. The cleaning brush 1 is sleeved on the support housing 312. The stopper 32 is provided on the support housing 312. The adjustment assembly 33 is provided in the support housing 312. During assembly, the stopper 32 and the adjustment assembly 33 are first installed in the support housing 312, and then the end plate 311 and the support housing 312 are connected.

[0043] Specifically, combined Figure 4 As shown, the end plate 311 and the support housing 312 are connected by a plurality of first fasteners 34. The connection hole 31101 is set to a polygonal shape, and the output shaft 21 of the motor 2 is set to a matching shape. When the output shaft 21 is inserted into the connection hole 31101, it can only move along the direction of its rotation axis and cannot rotate, so that the end plate 311 can rotate synchronously with the output shaft 21. In order to fix the end plate 311 to the output shaft 21, a second fastener 35 is provided at the end of the output shaft 21. The second fastener 35 is screwed into the output shaft 21 and blocks the end plate 311 to prevent the end plate 311 from coming off the output shaft 21. Optionally, both the first fastener 34 and the second fastener 35 can adopt structures such as screws, bolts, and snaps.

[0044] Optionally, the diameter of the end plate 311 is greater than the diameter of the support shell 312. After the cleaning brush 1 is sleeved on the support shell 312, the cleaning brush 1 abuts against the end plate 311. In order to prevent the cleaning brush 1 from rotating around the support shell 312, the end plate 311 is engaged with the cleaning brush 1 to limit the cleaning brush 1 from rotating around the support shell 312.

[0045] Specifically, combined Figure 1 and Figure 3 As shown, at least one limiting groove 31102 is provided on the end plate 311 facing the cleaning brush 1, and at least one limiting column 12 is correspondingly provided on the cleaning brush 1, and the limiting column 12 is inserted into the limiting groove 31102. When there are multiple limiting grooves 31102, the multiple limiting grooves 31102 are arranged at intervals around the support shell 312. In this embodiment, there are eight limiting grooves 31102, and four limiting columns 12 are provided, and the limiting grooves 31102 and the limiting columns 12 are evenly spaced.

[0046] like Figure 4 As shown, in order to realize the installation of the limiter 32, an adjustment hole 3121 is provided on the side wall where the support shell 312 and the cleaning brush 1 meet, and the aperture of the adjustment hole 3121 decreases from the inside of the side wall to the outside, and the minimum aperture of the adjustment hole 3121 is smaller than the maximum outer diameter of the limiter 32, so that the limiter 32 can be extended from the adjustment hole 3121 to the outside of the support shell 312 to limit the cleaning brush 1, while preventing the limiter 32 from falling out of the adjustment hole 3121. In this embodiment, the aperture of the adjustment hole 3121 gradually decreases from the inside of the side wall to the outside, forming a tapered hole.

[0047] Furthermore, the limiting member 32 is a spherical structural member, such as a steel ball. When the adjusting assembly 33 presses the limiting member 32 outward, the spherical limiting member 32 is easy to roll out; when the limiting member 32 is not pressed by the adjusting assembly 33, it will roll along the conical hole into the supporting shell 312 under the action of gravity, thereby releasing the limit on the cleaning brush 1.

[0048] Correspondingly, if Figure 2 and Figure 5 As shown, a limiting protrusion 13 is provided on the inner wall of the mounting hole 11 of the cleaning brush 1, and the limiting protrusion 13 abuts against the supporting shell 312. During the process of assembling the cleaning brush 1 to the supporting shell 312, the limiting member 32 retracts into the supporting shell 312, avoiding the limiting protrusion 13, and the limiting protrusion 13 passes through the adjustment hole 3121, so that the cleaning brush 1 is installed in place. Figure 2 In the state shown in FIG. , the limiting member 32 protrudes from the outer surface of the supporting shell 312 and acts as a block and limit to the limiting protrusion 13 .

[0049] Combine the following Figure 4 and Figure 5 The specific structure of the adjustment component 33 is described. The adjustment component 33 includes a limit drive block 331 and a reset member 332. The limit drive block 331 is movably arranged on the end surface of the support shell 312 away from the end plate 311. The limit drive block 331 abuts against the limit member 32. The limit drive block 331 moves in one direction to a first preset position ( Figure 4), the limiting member 32 is pressed by the limiting driving block 331 to protrude from the outer surface of the supporting shell 312; the limiting driving block 331 moves in another opposite direction to the second preset position ( Figure 5 ), the limit member 32 retracts into the outer surface of the support shell 312. The reset member 332 is drivingly connected to the limit drive block 331. When the limit drive block 331 is not subjected to external force, the reset member 332 resets the limit drive block 331 so that the limit drive block 331 locks the limit member 32 at a position protruding from the outer surface of the support shell 312. When the cleaning brush 1 needs to be disassembled, the limit drive block 331 is pressed to retract the limit member 32 into the support shell 312, thereby releasing the limit on the cleaning brush 1 so that the cleaning brush 1 can be installed or removed. After the installation or removal is completed, the limit drive block 331 is released so that the limit drive block 331 is reset under the action of the reset member 332 to continue to lock the limit member 32 at a position protruding from the outer surface of the support shell 312.

[0050] Specifically, the limit driving block 331 extends along its moving direction, and the limit driving block 331 includes an avoidance end 3311 and an abutment end 3312 arranged along its extending direction, the outer diameter of the abutment end 3312 is larger than the outer diameter of the avoidance end 3311, and the outer surface of the abutment end 3312 is smoothly connected to the outer surface of the avoidance end 3311. When the abutment end 3312 is aligned with the limit member 32, the limit member 32 is pressed outwardly so that the limit member 32 protrudes from the outer surface of the support shell 312; when the avoidance end 3311 faces the limit member 32, the limit member 32 will move into the support shell 312 to avoid the limit protrusion 13.

[0051] In order to ensure that the limit drive block 331 is installed stably, the end of the avoidance end 3311 can abut against the inner surface of the support shell 312 to limit the limit drive block 331 from escaping from the support shell 312. The avoidance end 3311 is provided with a groove, the bottom of which abuts against the inner surface of the support shell 312, and the end surface of the avoidance end 3311 can extend out of the support shell 312 to facilitate the pressing operation of the avoidance end 3311. A reset member 332 is provided between the abutting end 3312 and the end plate 311, and the reset member 332 applies elastic force to the limit drive block 331 so that the abutting end 3312 faces the limit member 32. Specifically, the reset member 332 is a spring.

[0052] Optionally, the end plate 311 includes an end plate body 3111 and a guide column 3112, and the guide column 3112 is arranged on the side of the end plate body 3111 facing the support shell 312. At least a part of the reset member 332 is sleeved on the guide column 3112, and one end of the reset member 332 abuts against the end plate body 3111, and the other end of the reset member 332 abuts against one end of the abutting end 3312 away from the avoidance end 3311. The guide column 3112 is provided with a connecting hole 31101, and the limit drive block 331 is provided with an operating hole 3310, and the limit drive block 331 is sleeved on the guide column 3112 through the operating hole 3310. In this way, the guide column 3112 guides the upward and downward sliding of the limit drive block 331 to prevent the limit drive block 331 from being deflected; in addition, the second fastener 35 can also be disassembled and assembled through the operating hole 3310.

[0053] Further, in order to facilitate the pressing operation of the limit driving block 331, the limit driving block 331 also includes a top cover 333, which is connected to the end of the avoidance end 3311 by a snap connection, and covers the operation hole 3310. When the limit driving block 331 is pressed, the top cover 333 can be pressed.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
