[0047] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0048] Reference is made below Figures 1 - 5 to describe the cleaning module 100, cleaning device and cleaning system according to the embodiments of the present utility model.

[0049] Referring to Figures 1 - 5 , the cleaning module 100 according to the first - aspect embodiment of the present utility model includes: a fixed frame 1, a lifting mechanism 2 and a driving mechanism. The driving mechanism can drive the lifting mechanism 2 to move up and down relative to the fixed frame 1.

[0050] The lifting mechanism 2 includes a lifting frame 21, a cleaning assembly 22 and a cutting assembly 23 provided on the lifting frame 21. The lifting frame 21 is flexibly connected to the fixed frame 1 and can move up and down relative to the fixed frame 1. The cleaning assembly 22 can contact the working surface to clean the working surface, and the cutting assembly 23 is used to cut the garbage attached to the cleaning assembly 22. For example, the cutting assembly 23 has a cutting opening, and the cutting opening of the cutting assembly 23 extends towards the cleaning assembly 22. Optionally, the working surface can be the ground, carpet, etc.

[0051] The driving mechanism is provided on the lifting frame 21 and includes a driving motor 31, a transmission shaft 32, a first transmission member 33, a second transmission member 34 and a selection transmission member 35. The driving motor 31 is connected to the transmission shaft 32 to drive the transmission shaft 32 to rotate. The two ends in the length direction of the transmission shaft 32 are respectively sleeved with the first transmission member 33 and the selection transmission member 35. The outer periphery of the selection transmission member 35 is sleeved with the second transmission member 34, and the second transmission member 34 is fixed relative to the selection transmission member 35. The driving motor 31 outputs a driving force and transmits it to the first transmission member 33 and the selection transmission member 35 through the transmission shaft 32. When the driving direction of the driving motor 31 is the same as the transmission direction of the selection transmission member 35, the selection transmission member 35 drives the second transmission member 34 to move.

[0052] Among them, the first transmission member 33 and the cutting assembly 23 can be in transmission connection to drive the cutting assembly 23 to move. For example, at least part of the cutting assembly 23 can move horizontally relative to the lifting frame 21 to cut the garbage attached to the cleaning assembly 22.

[0053] The second transmission member 34 is flexibly connected to the lifting frame 21. When the driving motor 31 rotates forward, there is a transmission connection between the transmission shaft 32 and the second transmission member 34. The transmission shaft 32 transmits power to the second transmission member 34 through the selection transmission member 35, and the second transmission member 34 drives the lifting frame 21 to move upward. When the driving motor 31 rotates reversely, the transmission connection between the transmission shaft 32 and the second transmission member 34 is disconnected, and the selection transmission member 35 cannot transmit the power from the transmission shaft 32 to the second transmission member 34, and the lifting frame 21 moves downward under its own gravity. This enables the cleaning assembly 22 provided on the lifting frame 21 to move upward relative to the working surface to separate from the working surface. In this way, it is possible to save the driving motor 31 that is separately provided for driving the lifting mechanism 2 to move upward to drive the cleaning assembly 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple, and beneficial to reducing the cost of the cleaning module 100; and the transmission structure between the transmission shaft 32 and the second transmission member 34 is simple, so that the structure of the driving mechanism is simple, which is also beneficial to simplifying the structure of the cleaning module 100 and making the assembly of the cleaning module 100 simple.

[0054] Optionally, the cleaning assembly 22 can be a rotary brush assembly or a mopping assembly; for example, when the cleaning assembly 22 is a rotary brush assembly, the first transmission member 33 is in transmission connection with the cutting assembly 23 to drive the cutting assembly 23 to cut foreign matters, such as hair, wound on the rotary brush assembly.

[0055] For example, when the driving motor 31 rotates forward, the driving motor 31 drives the first transmission member 33 to rotate through the transmission shaft 32. The first transmission member 33 drives the cutting assembly 23 to move horizontally relative to the lifting frame 21, and drives the second transmission member 34 to rotate through the transmission shaft 32 and the selection transmission member 35. The second transmission member 34 drives the lifting frame 21 to move upward, so that the lifting frame 21 drives the cleaning assembly 22 to move upward, and the cleaning assembly 22 is separated from the working surface.

[0056] For example, when the driving motor 31 rotates reversely, the driving motor 31 drives the first transmission member 33 to rotate through the transmission shaft 32. The first transmission member 33 drives the cutting assembly 23 to move horizontally relative to the lifting frame 21; the transmission connection between the transmission shaft 32 and the second transmission member 34 is disconnected, and the lifting frame 21 and the cleaning assembly 22, the cutting assembly 23, etc. provided on the lifting frame 21 move downward under their own action, and the cleaning assembly 22 contacts the working surface.

[0057] For example, the cleaning component 22 is a rotary brush component. When the cleaning module 100 is applied to a cleaning device and the cleaning device is performing the mopping function, to prevent the rotary brush component from causing secondary pollution to the floor that has been mopped, the cleaning device can control the driving motor 31 to rotate in the forward direction. The driving motor 31 transmits power to the selection transmission member 35 through the transmission shaft 32. The selection transmission member 35 drives the second transmission member 34 that is relatively fixed to it to rotate. The second transmission member 34 drives the lifting frame 21 to move upward, so that the lifting frame 21 drives the rotary brush component provided thereon to move upward and separate from the ground.

[0058] According to the cleaning module 100 of the embodiment of the present utility model, by providing the transmission shaft 32 connected to the driving motor 31 and sleeving the first transmission member 33 and the selection transmission member 35 at both ends in the length direction of the transmission shaft 32 respectively, and sleeving the second transmission member 34 flexibly connected to the lifting frame 21 on the outer periphery of the selection transmission member 35, the driving motor 31 can not only drive the cutting component 23 to move through the first transmission member 33, but also drive the selection transmission member 35 to rotate when the driving motor 31 rotates forward, so as to drive the lifting frame 21 to move upward through the second transmission member 34. Thus, the cleaning component 22 provided on the lifting frame 21 can move upward relative to the working surface to separate from the working surface. This can eliminate the need to provide a separate driving motor 31 for driving the lifting mechanism 2 to move upward to drive the cleaning component 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple, and reducing the cost of the cleaning module 100.

[0059] In addition, by sleeving the selection transmission member 35 at one end of the transmission shaft 32, when the driving motor 31 rotates forward, the transmission shaft 32 can transmit power to the second transmission member 34 through the selection transmission member 35. When the driving motor 31 rotates in the reverse direction, the selection transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, it can be realized to control the driving motor 31 to drive the cutting component 23 to move or drive the cutting component 23 to move and the lifting mechanism 2 to move upward simultaneously according to the working needs of the cleaning module 100. The transmission structure between the transmission shaft 32 and the second transmission member 34 is simple, so that the structure of the driving mechanism is simple. This is also beneficial to simplifying the structure of the cleaning module 100 and making the assembly of the cleaning module 100 simple.

[0060] Reference Figures 4 - 5, according to some embodiments of the present invention, the selected transmission member 35 is a one-way bearing. By making the selected transmission member 35 a one-way bearing, the one-way bearing has a simple structure, and the one-way bearing can reliably and stably transmit torque unidirectionally. So that when the driving motor 31 rotates forward, the selected transmission member 35 can reliably and stably transmit power to the second transmission member 34, and when the driving motor 31 rotates in the reverse direction, it can also effectively prevent the selected transmission member 35 from transmitting power to the second transmission member 34 and interfering with the normal operation of the cleaning module 100 as a whole.

[0061] Reference Figure 4 , according to some alternative embodiments of the present invention, a limiting convex block is provided on one of the outer peripheral wall of the selected transmission member 35 and the inner peripheral wall of the second transmission member 34, and a limiting groove is provided on the other. The limiting convex block is received in the limiting groove.

[0062] For example, a limiting convex block is provided on the outer peripheral wall of the selected transmission member 35, and a limiting groove is provided on the inner peripheral wall of the second transmission member 34. The limiting convex block is received in the limiting groove to relatively fix the selected transmission member 35 and the second transmission member 34.

[0063] For example, a limiting groove is provided on the outer peripheral wall of the selected transmission member 35, and a limiting convex block is provided on the inner peripheral wall of the second transmission member 34. The limiting convex block is received in the limiting groove to relatively fix the selected transmission member 35 and the second transmission member 34.

[0064] By providing a limiting convex block on one of the outer peripheral wall of the selected transmission member 35 and the inner peripheral wall of the second transmission member 34 and a limiting groove on the other, and making the limiting convex block received in the limiting groove, the structures of the limiting groove and the limiting convex block are simple, so that the structures of the selected transmission member 35 and the second transmission member 34 are simple and the cooperative transmission relationship between the selected transmission member 35 and the second transmission member 34 is simple.

[0065] Reference Figure 4 , according to some embodiments of the present invention, the driving mechanism further includes a worm and worm gear transmission mechanism. The worm and worm gear transmission mechanism includes a worm wheel 36 and a worm 37 that mesh with each other. The worm wheel 36 is sleeved on the transmission shaft 32 and is located between the first transmission member 33 and the second transmission member 34, and the worm 37 is provided at the output end of the driving motor 31. Optionally, the output end of the driving motor 31 and the worm 37 are coaxially connected.

[0066] By providing the worm and worm gear transmission mechanism, the worm and worm gear mechanism can stably transmit the power of the driving motor 31 to the transmission shaft 32. When the driving motor 31 rotates forward, the transmission of the worm 36 and the worm 37 can stably and safely drive the lifting frame 21 so that the lifting frame 21 can rise smoothly.

[0067] Reference Figures 4 - 5, according to some alternative embodiments of the present utility model, the cleaning module 100 further includes a box body 4 having a receiving cavity, the transmission shaft 32 is rotatably disposed in the receiving cavity, the box body 4 includes a first box body 41, a second box body 42 and a cover 43 that are sequentially arranged and connected along the length direction of the transmission shaft 32, the receiving cavity includes a first receiving cavity 44 and a second receiving cavity 45 that are arranged along a first direction and communicate with each other, the first box body 41 and the second box body 42 are detachably connected and define the first receiving cavity 44, the second box body 42 and the cover 43 are detachably connected and define the second receiving cavity 45, at least part of the worm gear 36 and the first transmission member 33 are received in the first receiving cavity 44, and the selection transmission member 35 and the second transmission member 34 are received in the second receiving cavity 45.

[0068] For example, the assembly process of the cleaning module 100 may include the following steps:

[0069] First, the first transmission member 33 and the worm gear 36 are sleeved on the transmission shaft 32; then, the transmission shaft 32 sleeved with the first transmission member 33 and the worm gear 36 is first assembled into the first box body 41, and the second box body 42 is connected to the first box body 41 to define the first receiving cavity 44; then, the selection transmission member 35 is sleeved on the other end of the transmission shaft 32, and the second transmission member 34 is sleeved on the outer periphery of the selection transmission member 35; then, the cover 43 is connected to the second box body 42 to define the second receiving cavity 45.

[0070] By making the box body 4 into a first box body 41, a second box body 42 and a third box body 4 that are detachably connected, and making the first box body 41 and the second box body 42 define the first receiving cavity 44, and the second box body 42 and the third box body 4 define the second receiving cavity 45, in this way, during the assembly process of the cleaning module 100, after the worm gear 36 and the first transmission member 33 are received in the first receiving cavity 44, the selection transmission member 35 and the second transmission member 34 in the second receiving cavity 45 can be installed. The second box body 42 can limit the components in the first receiving cavity 44 to prevent them from affecting the assembly of the components in the second receiving cavity 45, which is beneficial to improving the assembly efficiency; in addition, in this way, when it is necessary to repair, maintain or replace the components in the first receiving cavity 44 or the second receiving cavity 45, there is no need to disassemble the entire box body 4, which is convenient for repairing, maintaining and replacing the components in the box body 4.

The snap ring 10 is sleeved on the outer peripheral side of the transmission shaft 32 and is located on the side of the second transmission member 34 away from the worm wheel 36.

One end of the towing rope 5 is connected to the second transmission member 34 so that a part of the towing rope 5 can be wound around the second transmission member 34. The other end of the towing rope 5 is connected to the lifting frame 21. A supporting portion 6 is formed on the fixing frame 1. The part of the towing rope 5 between the two ends of the towing rope 5 is supported by the supporting portion 6, and the height of the supporting portion 6 is always higher than the two ends of the towing rope 5. Wherein, when the driving motor 31 rotates forward, the second transmission member 34 rotates to wind the towing rope 5 around the second transmission member 34. When the driving motor 31 rotates in reverse, the second transmission member 34 releases the towing rope 5.

[0074] By making the cleaning module 100 include the towing rope 5 and making the second transmission member 34 a wire winding wheel, one end of the towing rope 5 is connected to the second transmission member 34, the other end of the towing rope 5 is connected to the lifting frame 21, and the part of the towing rope 5 between the two ends of the towing rope 5 is supported by the supporting portion 6 on the fixing frame 1. The arrangement of the towing rope 5 and the supporting portion 6 realizes the effective transmission between the second transmission member 34 and the lifting frame 21. The supporting portion 6 provides a supporting effect on the towing rope 5 and keeps the towing rope 5 in a tensioned state. So that during the process of the towing rope 5 being wound around the second transmission member 34, under the supporting action of the supporting portion 6, the two ends of the towing rope 5 can apply an upward acting force to the lifting mechanism 2, so that the lifting mechanism 2 moves upward relative to the fixing frame 1.

[0075] By the forward and reverse rotation of the driving motor 31 and in cooperation with the winding and release of the towing rope 5, the second transmission member 34 can stably drive the lifting frame 21 to move upward, and the lifting frame 21 can gently descend under the action of gravity; in addition, as a transmission component, the towing rope 5 has a simple structure and requires a small installation space, which is beneficial to optimizing the spatial layout of the cleaning module 100.

[0076] For example, the cleaning component 22 is a roller brush component. When the cleaning module 100 is applied to a cleaning device and the cleaning device is performing a mopping function, to avoid the roller brush component causing secondary pollution to the floor that has been mopped, the cleaning device can control the driving motor 31 to rotate in the forward direction. The driving motor 31 transmits power to the selection transmission part 35 through the transmission shaft 32. The selection transmission part 35 drives the second transmission part 34 fixed relative to it to rotate. The second transmission part 34 rotates to wind the traction rope 5 around the second transmission part 34. The traction rope 5 drives the lifting frame 21 to move upward, so that the lifting frame 21 drives the roller brush component provided thereon to move upward and separate from the ground. When the roller brush component reaches a preset height from the ground, the driving motor 31 stops rotating, and the roller brush component can be kept at the preset height from the ground. When it is necessary to control the roller brush component to fall to the ground, it is only necessary to control the driving motor 31 to rotate in the reverse direction, and the lifting mechanism 2 falls under the action of gravity to contact the ground.

[0077] Reference Figures 1 - 2 , according to some optional embodiments of the present invention, a support limit groove 61 is formed at the top of the support part 6. The traction rope 5 is received in the support limit groove 61 and can move along the extending direction of the support limit groove 61. The height of the bottom wall of the support limit groove 61 is always higher than the two ends of the traction rope 5. By forming the support limit groove 61 at the top of the support part 6 and allowing the traction rope 5 to be received in the support limit groove 61 and move along the extending direction of the support limit groove 61, the support limit groove 61 forms a limiting effect and a guiding effect on the traction rope 5.

[0078] Reference Figures 1 - 2 , according to some optional embodiments of the present invention, a traction sleeve 7 is further included. The traction rope 5 is threaded through the traction sleeve 7, and the traction sleeve 7 is received in the support limit groove 61. By providing the traction sleeve 7 received in the support limit groove 61 and threading the traction rope 5 through the traction sleeve 7, the traction sleeve 7 can further form a limiting and guiding effect on the traction rope 5, and the traction sleeve 7 can form a protective effect to reduce the mutual friction between the traction rope 5 and the support limit groove 61.

[0079] Optionally, the traction sleeve 7 is a flexible tube; optionally, the traction rope 5 is a steel wire rope.

[0080] Reference Figures 1 - 2, According to some alternative embodiments of the present utility model, the support limiting groove 61 includes a first groove section 611, a second groove section 612, and a third groove section 613 arranged side by side along the extending direction of the support limiting groove 61. The traction sleeve 7 includes a first pipe body 71, a second pipe body 72, and a third pipe body 73 connected in sequence. The first pipe body 71 and the third pipe body 73 are respectively fixed in the first groove section 611 and the third groove section 613, and the second pipe body 72 is received in the second groove section 612. By making the support limiting groove 61 include the first groove section 611, the second groove section 612, and the third groove section 613, and making the traction sleeve 7 include the first pipe body 71, the second pipe body 72, and the third pipe body 73, and fixing the first pipe body 71 and the third pipe body 73 in the first groove section 611 and the third groove section 613 respectively, it is beneficial for the traction sleeve 7 to be stably supported on the support portion 6, and it can prevent the traction sleeve 7 from moving randomly when the traction rope 5 moves relative to the support limiting groove 61.

[0081] Optionally, the first groove section 611, the second groove section 612, and the third groove section 613 are spaced apart from each other.

[0082] Reference Figures 1 - 3 , According to some alternative embodiments of the present utility model, a fixed limiting portion 8 is provided on the lifting frame 21. A through hole 81 is formed on the fixed limiting portion 8. The other end of the traction rope 5 is passed through the through hole 81 and an anti - detachment block 9 is provided at the other end of the traction rope 5. The anti - detachment block 9 is located below the through hole 81 and is used to prevent the other end of the traction rope 5 from detaching upward from the through hole 81. By providing the fixed limiting portion 8 with the through hole 81 on the lifting frame 21 so that the other end of the traction rope 5 can pass through the through hole 81, and by providing the anti - detachment block 9 at the other end of the traction rope 5 and making the anti - detachment block 9 located below the through hole 81, when one end of the traction rope 5 is wound around the second transmission member 34, the other end of the traction rope 5 moves upward to contact the fixed limiting portion 8. Through the contact action between the anti - detachment block 9 and the fixed limiting portion 8, the power can be stably transmitted to the lifting frame 21, so that the lifting frame 21 can move upward stably under the action of the traction rope 5.

[0083] Reference Figures 1 - 3, according to some alternative embodiments of the present utility model, the fixing frame 1 covers the upper part of the lifting frame 21. A first through opening 11 and a second through opening 12 are formed on the fixing frame 1. The first through opening 11 and the second through opening 12 are located on both sides of the supporting part 6. The first through opening 11 is used to avoid the fixed limiting part 8, and the second through opening 12 is used to avoid the second transmission member 34. By forming the first through opening 11 for avoiding the fixed limiting part 8 and the second through opening 12 for avoiding the second transmission member 34 on the fixing frame 1, it is convenient to connect the other end of the traction rope 5 to the fixed limiting part 8 through the first through opening 11 and to maintain their connection relationship, etc. It is also convenient to connect one end of the traction rope 5 to the second transmission member 34 through the second through opening 12 and to maintain their connection relationship, etc.

[0084] According to some alternative embodiments of the present utility model, the rotation axis of the first transmission member 33 extends along a first direction, and at least part of the cutting assembly 23 reciprocates linearly in the horizontal direction relative to the cleaning assembly 22. The first transmission member 33 is formed as a cam. The cutting assembly 23 includes a fixed cutter, a moving cutter and a reset member; the reset member is arranged between the fixed cutter and the moving cutter. A cutting opening is formed between the fixed cutter and the moving cutter. The cam contacts or connects with the moving cutter, and the cam and the reset member are used to drive the moving cutter to reciprocate relative to the fixed cutter along a second direction.

[0085] The cam contacts the side surface of the moving cutter facing away from the fixed cutter, and the reset member can be a spring connected between the fixed cutter and the moving cutter. Thus, when the cam drives the moving cutter to approach the fixed cutter, the spring is in a compressed state, and the fixed cutter and the moving cutter cooperate to complete the shearing action; when the cam moves away from the moving cutter, the spring returns from the compressed state to the natural elongation state, and during this process, the spring drives the moving cutter away from the fixed cutter so that the cutting opening between the fixed cutter and the moving cutter is opened, thereby preparing for the next cutting action. It can be seen that during the rotation of the cam along with the transmission shaft 32, the moving cutter reciprocates relative to the fixed cutter under the combined action of the cam and the reset member, so as to perform a cutting action on the foreign matters wound on the roller brush assembly at a fixed frequency.

[0086] Optionally, the reset member can also be a first magnet and a second magnet respectively arranged on the fixed cutter and the moving cutter, and the magnetic poles of the end of the first magnet facing the second magnet and the end of the second magnet facing the first magnet are the same. Thus, when the cam moves away from the moving cutter, based on the repulsive magnetic force between the first magnet and the second magnet, the moving cutter can be driven away from the fixed cutter, so as to achieve the purpose of opening the cutting opening between the fixed cutter and the moving cutter.

[0087] The cleaning device according to the second aspect embodiment of the present utility model includes: a device body and the above-mentioned cleaning module 100, and the fixing frame 1 of the cleaning module 100 is fixed to the device body.

[0088] According to the cleaning device of the embodiment of the present utility model, by providing the above-mentioned cleaning module 100, the cleaning module 100 is provided with a transmission shaft 32 connected to a driving motor 31, and a first transmission member 33 and a selection transmission member 35 are respectively sleeved at both ends in the length direction of the transmission shaft 32, and a second transmission member 34 flexibly connected to the lifting frame 21 is sleeved on the outer periphery of the selection transmission member 35. So that the driving motor 31 can not only drive the cutting assembly 23 to move through the first transmission member 33, but also drive the selection transmission member 35 to rotate when the driving motor 31 rotates forward, and drive the lifting frame 21 to move upward through the second transmission member 34. Thus, the cleaning assembly 22 provided on the lifting frame 21 can move upward relative to the working surface to be separated from the working surface. In this way, it is possible to save the driving motor 31 that is separately provided for driving the lifting mechanism 2 to move upward to drive the cleaning assembly 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple, and beneficial to reducing the cost of the cleaning module 100. Further, the structure of the cleaning device can be simplified, making the assembly of the cleaning device simple, and beneficial to reducing the cost of the cleaning device.

[0089] In addition, by sleeving a selection transmission member 35 at one end of the transmission shaft 32, when the driving motor 31 rotates forward, the transmission shaft 32 can transmit power to the second transmission member 34 through the selection transmission member 35, and when the driving motor 31 rotates in the reverse direction, the selection transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, it is possible to control the driving motor 31 to drive the cutting assembly 23 to move or drive the cutting assembly 23 to move and the lifting mechanism 2 to move upward according to the working needs of the cleaning module 100. The transmission structure between the transmission shaft 32 and the second transmission member 34 is simple, so that the structure of the driving mechanism is simple. This is also beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple. Further, the structure of the cleaning device can also be simplified, making the assembly of the cleaning device simple.

Thus, the driving motor 31 can not only drive the cutting assembly 23 to move through the first transmission member 33, but also drive the selection transmission member 35 to rotate when the driving motor 31 rotates forward, so as to drive the lifting frame 21 to move upward through the second transmission member 34. Therefore, the cleaning assembly 22 provided on the lifting frame 21 can move upward relative to the working surface to be separated from the working surface. In this way, it is possible to omit the driving motor 31 that is separately provided to drive the lifting mechanism 2 to move upward to drive the cleaning assembly 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple, and beneficial to reducing the cost of the cleaning module 100. Further, the structure of the cleaning system can be simplified, making the assembly of the cleaning system simple, and beneficial to reducing the cost of the cleaning device.

[0092] In addition, by sleeving a selection transmission member 35 at one end of the transmission shaft 32, when the driving motor 31 rotates forward, the transmission shaft 32 can transmit power to the second transmission member 34 through the selection transmission member 35, while when the driving motor 31 rotates reversely, the selection transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, it is possible to control the driving motor 31 to drive the cutting assembly 23 to move or drive the cutting assembly 23 and the lifting mechanism 2 to move upward simultaneously according to the working needs of the cleaning module 100. The transmission structure between the transmission shaft 32 and the second transmission member 34 is simple, so that the structure of the driving mechanism is simple. This is also beneficial to simplifying the structure of the cleaning module 100, making the assembly of the cleaning module 100 simple.
