Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to a cleaning module, cleaning equipment, and cleaning system. Background Technology

[0002] In related technologies, cleaning equipment includes cleaning components (such as roller brush components and mopping components) for cleaning work surfaces (such as floors, carpets, etc.) and cutting devices that can move relative to the cleaning components to cut away debris adhering to them. The cleaning equipment has multiple cleaning functions (such as sweeping and mopping), and is equipped with cleaning components corresponding to each function. When the cleaning equipment performs a specific cleaning function according to work requirements, some cleaning components need to move upwards relative to the equipment body to separate them from the work surface, thus preventing the cleaning effect from deteriorating. For example, when sweeping the floor, the roller brush component is in contact with the floor, while the mopping component is separate; when mopping, the mopping component is in contact with the floor, while the roller brush component is separate.

[0003] However, the complex structures driving the cutting device and cleaning components on the cleaning equipment result in a complex overall structure and cumbersome assembly. Therefore, improvements are needed. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide a cleaning module that, by setting a transmission shaft connected to a drive motor, and having a first transmission member and a selection transmission member respectively fitted at both ends along the length of the transmission shaft, and a second transmission member flexibly connected to a lifting frame fitted around the outer periphery of the selection transmission member, the transmission structure between the transmission shaft and the second transmission member is simple. This eliminates the need for a separate drive motor to drive the lifting mechanism upwards to move the cleaning components upwards, thus simplifying the structure of the cleaning module and making its assembly easier.

[0005] The present invention also proposes a cleaning device having the above-described cleaning module.

[0006] The present invention also proposes a cleaning system having the above-described cleaning equipment.

[0007] According to a first aspect of the present invention, a cleaning module includes: a fixed frame; a lifting mechanism including a lifting frame and a cleaning component and a cutting component disposed on the lifting frame, the lifting frame being flexibly connected to the fixed frame and movable up and down relative to the fixed frame, the cutting component being used to cut debris attached to the cleaning component; and a driving mechanism disposed on the lifting frame and including a drive motor, a transmission shaft, a first transmission component, a second transmission component, and a selective transmission component, the drive motor being connected to the transmission shaft to drive the transmission shaft to rotate, the first transmission component and the selective transmission component being respectively sleeved at both ends of the transmission shaft in the length direction, the second transmission component being sleeved on the outer periphery of the selective transmission component, and the second transmission component being fixed relative to the selective transmission component.

[0008] The first transmission component is tractably connected to the cutting assembly to drive the cutting assembly to move. The second transmission component is flexibly connected to the lifting frame. When the drive motor rotates in the forward direction, the transmission shaft is tractively connected to the selected transmission component, and the second transmission component drives the lifting frame to move upward. When the drive motor rotates in the reverse direction, the transmission shaft is disconnected from the selected transmission component, and the lifting frame moves downward under its own gravity.

[0009] According to an embodiment of the present invention, the cleaning module is provided with a drive shaft connected to a drive motor, and a first transmission member and a selection transmission member are respectively sleeved at both ends of the drive shaft along its length. A second transmission member flexibly connected to the lifting frame is sleeved on the outer periphery of the selection transmission member. This allows the drive motor to not only drive the cutting component to move through the first transmission member, but also to drive the selection transmission member to rotate simultaneously when the drive motor rotates in the forward direction, thereby driving the lifting frame to move upward through the second transmission member. This allows the cleaning component located on the lifting frame to move upward relative to the working surface. This eliminates the need for a separate drive motor to drive the lifting mechanism to move upward and thus drive the cleaning component to move upward, which simplifies the structure of the cleaning module, makes the cleaning module easier to assemble, and helps reduce the cost of the cleaning module.

When the drive motor rotates in the reverse direction, the selective transmission component will not transmit the force from the drive shaft to the second transmission component. In this way, the drive motor can be controlled to drive the cutting component to move or simultaneously drive the cutting component and the lifting mechanism to move upward according to the working needs of the cleaning module. The transmission structure between the drive shaft and the second transmission component is simple, which makes the structure of the drive mechanism simple.

[0021] According to some optional embodiments of the present invention, the fixing frame is disposed on the upper part of the lifting frame, and a first opening and a second opening are formed on the fixing frame.

This allows the drive motor to drive the cutting component to move through the first transmission member, and also to drive the selection transmission member to rotate when the drive motor rotates in the forward direction, so as to drive the lifting frame to move upward through the second transmission member. This allows the cleaning component on the lifting frame to move upward relative to the working surface. This eliminates the need for a separate drive motor to drive the lifting mechanism to move upward and drive the cleaning component to move upward, which simplifies the structure of the cleaning module, makes the cleaning module easier to assemble, and reduces the cost of the cleaning module.

In this way, the drive motor can be controlled to drive the cutting component to move or simultaneously drive the cutting component and the lifting mechanism to move upward according to the working needs of the cleaning module. The transmission structure between the drive shaft and the second transmission component is simple, which makes the structure of the drive mechanism simple.

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following is for reference. Figures 1-5 The present invention describes a cleaning module 100, a cleaning device, and a cleaning system according to embodiments thereof.

[0049] refer to Figures 1-5 According to a first aspect embodiment of the present invention, the cleaning module 100 includes: a fixed frame 1, a lifting mechanism 2 and a driving mechanism, wherein 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 and a cleaning component 22 and a cutting component 23 disposed 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 component 22 can contact the working surface to clean the working surface, and the cutting component 23 is used to cut the debris attached to the cleaning component 22. For example, the cutting component 23 has a cutting opening, and the cutting opening of the cutting component 23 extends toward the cleaning component 22. Optionally, the working surface can be a floor, carpet, etc.

[0051] The drive mechanism is located on the lifting frame 21 and includes a drive motor 31, a transmission shaft 32, a first transmission component 33, a second transmission component 34, and a selective transmission component 35. The drive motor 31 is connected to the transmission shaft 32 to drive the transmission shaft 32 to rotate. The first transmission component 33 and the selective transmission component 35 are respectively sleeved at both ends of the transmission shaft 32 along its length. The second transmission component 34 is sleeved on the outer periphery of the selective transmission component 35 and is fixed relative to the selective transmission component 35. The drive motor 31 outputs driving force and transmits it to the first transmission component 33 and the selective transmission component 35 through the transmission shaft 32. When the driving direction of the drive motor 31 is consistent with the transmission direction of the selective transmission component 35, the selective transmission component 35 drives the second transmission component 34 to move.

[0052] The first transmission member 33 is tractably connected to the cutting assembly 23 to drive the cutting assembly 23 to move. For example, at least a portion 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 component 34 is flexibly connected to the lifting frame 21. When the drive motor 31 rotates in the forward direction, the transmission shaft 32 and the second transmission component 34 are connected by transmission. The transmission shaft 32 transmits power to the second transmission component 34 through the selective transmission component 35. The second transmission component 34 drives the lifting frame 21 to move upward. When the drive motor 31 rotates in the reverse direction, the transmission connection between the transmission shaft 32 and the second transmission component 34 is broken. The selective transmission component 35 cannot transmit the power from the transmission shaft 32 to the second transmission component 34, and the lifting frame 21 moves downward under its own gravity. This allows the cleaning component 22, located on the lifting frame 21, to move upward relative to the working surface and separate from it. This eliminates the need for a separate drive motor 31 to drive the lifting mechanism 2 upward and thus the cleaning component 22 upward. This simplifies the structure of the cleaning module 100, making its assembly easier and reducing its cost. Furthermore, the transmission structure between the drive shaft 32 and the second transmission component 34 is simple, resulting in a simple drive mechanism structure. This also simplifies the structure of the cleaning module 100 and makes its assembly easier.

[0054] Optionally, the cleaning component 22 may be a roller brush assembly or a mopping assembly; for example, the cleaning component 22 may be a roller brush assembly, and the first transmission member 33 may be connected to the cutting component 23 to drive the cutting component 23 to cut foreign objects, such as hair, wrapped around the roller brush assembly.

[0055] For example, when the drive motor 31 rotates in the forward direction, the drive motor 31 drives the first transmission component 33 to rotate through the transmission shaft 32. The first transmission component 33 drives the cutting component 23 to move horizontally relative to the lifting frame 21, and drives the second transmission component 34 to rotate through the transmission shaft 32 and the selective transmission component 35. The second transmission component 34 drives the lifting frame 21 to move upward, thereby the lifting frame 21 drives the cleaning component 22 to move upward, and the cleaning component 22 separates from the working surface.

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

[0057] For example, the cleaning component 22 is a roller brush component. When the cleaning module 100 is applied to the cleaning equipment and the cleaning equipment is performing the mopping function, in order to avoid the roller brush component causing secondary pollution to the floor after mopping, the cleaning equipment can control the drive motor 31 to rotate in the forward direction. The drive motor 31 transmits power to the selection transmission component 35 through the transmission shaft 32. The selection transmission component 35 drives the second transmission component 34, which is fixed to it, to rotate. The second transmission component 34 drives the lifting frame 21 to move upward, thereby causing the lifting frame 21 to drive the roller brush component mounted on it to move upward and separate from the floor.

[0058] According to the present invention, the cleaning module 100 is provided with a transmission shaft 32 connected to the drive motor 31, and a first transmission member 33 and a selection transmission member 35 respectively sleeved at both ends of the transmission shaft 32 along its length. A second transmission member 34 flexibly connected to the lifting frame 21 is sleeved on the outer periphery of the selection transmission member 35. This allows the drive motor 31 to drive the cutting component 23 to move through the first transmission member 33, and also to drive the selection transmission member 35 to rotate when the drive motor 31 rotates in the forward direction, so as to drive the lifting frame 21 to move upward through the second transmission member 34. This allows the cleaning component 22 on the lifting frame 21 to move upward relative to the working surface and separate from the working surface. This eliminates the need for a separate drive motor 31 for driving the lifting mechanism 2 to move upward and thus driving the cleaning component 22 to move upward, which simplifies the structure of the cleaning module 100, makes the cleaning module 100 easier to assemble, and helps to reduce the cost of the cleaning module 100.

[0059] In addition, by fitting a selective transmission member 35 at one end of the transmission shaft 32, when the drive motor 31 rotates in the forward direction, the transmission shaft 32 can transmit power to the second transmission member 34 through the selective transmission member 35. When the drive motor 31 rotates in the reverse direction, the selective transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, the drive motor 31 can be controlled to drive the cutting component 23 to move or simultaneously drive the cutting component 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, which makes the structure of the drive mechanism simple. This also helps to simplify the structure of the cleaning module 100 and makes the assembly of the cleaning module 100 easy.

[0060] refer to Figures 4-5According to some embodiments of the present invention, the transmission component 35 is selected as a one-way bearing. By selecting the transmission component 35 as a one-way bearing, the one-way bearing has a simple structure and can reliably and stably transmit torque in one direction. This allows the transmission component 35 to reliably and stably transmit power to the second transmission component 34 when the drive motor 31 rotates in the forward direction. When the drive motor 31 rotates in the reverse direction, it can also effectively prevent the transmission component 35 from transmitting power to the second transmission component 34, thus avoiding interference with the normal operation of the cleaning module 100 as a whole.

[0061] refer to Figure 4 According to some optional embodiments of the present invention, one of the outer peripheral wall of the transmission member 35 and the inner peripheral wall of the second transmission member 34 is provided with a limiting protrusion and the other is provided with a limiting groove, and the limiting protrusion is accommodated in the limiting groove.

[0062] For example, the outer peripheral wall of the selector transmission member 35 is provided with a limiting protrusion, and the inner peripheral wall of the second transmission member 34 is provided with a limiting groove. The limiting protrusion is accommodated in the limiting groove so that the selector transmission member 35 and the second transmission member 34 are relatively fixed.

[0063] For example, the outer peripheral wall of the selector transmission member 35 is provided with a limiting groove, and the inner peripheral wall of the second transmission member 34 is provided with a limiting protrusion. The limiting protrusion is accommodated in the limiting groove so that the selector transmission member 35 and the second transmission member 34 are relatively fixed.

[0064] By providing a limiting protrusion on one of the outer peripheral wall of the selector transmission member 35 and a limiting groove on the other, and by having the limiting protrusion accommodated within the limiting groove, the structures of the limiting groove and the limiting protrusion are simple, thereby simplifying the structure of the selector transmission member 35 and the second transmission member 34, as well as the cooperative transmission relationship between the selector transmission member 35 and the second transmission member 34.

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

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

[0067] refer to Figures 4-5According to some optional embodiments of the present invention, the cleaning module 100 further includes a housing 4 having a receiving cavity, a drive shaft 32 being rotatably disposed in the receiving cavity, the housing 4 including a first housing 41, a second housing 42 and a cover 43 arranged and connected sequentially along the length direction of the drive shaft 32, the receiving cavity including a first receiving cavity 44 and a second receiving cavity 45 arranged and connected along a first direction, the first housing 41 and the second housing 42 being detachably connected and defining the first receiving cavity 44, the second housing 42 and the cover 43 being detachably connected and defining the second receiving cavity 45, at least a portion of the worm gear 36 and the first transmission member 33 being received in the first receiving cavity 44, and the selective transmission member 35 and the second transmission member 34 being 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 fitted onto the transmission shaft 32; then, the transmission shaft 32 with the first transmission member 33 and the worm gear 36 fitted onto it is first assembled onto the first housing 41, and the second housing 42 is connected to the first housing 41 to define and form the first receiving cavity 44; next, the selective transmission member 35 is fitted onto the other end of the transmission shaft 32, and the second transmission member 34 is fitted onto the outer periphery of the selective transmission member 35; then, the cover 43 is connected to the second housing 42 to define and form the second receiving cavity 45.

[0070] By forming the housing 4 into a detachably connected first housing 41, second housing 42, and third housing 4, and by defining the first housing 41 and second housing 42 as a first receiving cavity 44, and the second housing 42 and third housing 4 as a second receiving cavity 45, during the assembly of the cleaning module 100, the worm gear 36 and the first transmission component 33 can be accommodated in the first receiving cavity 44 first, and then the selection transmission component 35 and the second transmission component 34 in the second receiving cavity 45 can be installed. The second housing 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, thereby improving assembly efficiency. In addition, when it is necessary to inspect, maintain, or replace the components in the first receiving cavity 44 or the second receiving cavity 45, it is not necessary to disassemble the entire housing 4, thus facilitating the inspection, maintenance, and replacement of the components in the housing 4.

[0071] Optionally, the drive motor 31 is located outside the housing 4 and can be connected to the housing 4. The rotation axis of the output end of the drive motor 31 intersects the axial direction of the transmission shaft 32. For example, the rotation axis of the output end of the drive motor 31 is perpendicular to the axial direction of the transmission shaft 32.

[0072] Optionally, the cleaning module 100 also includes a retaining ring 10, which is engaged on the outer periphery of the drive shaft 32 and located on the side of the second drive member 34 away from the worm gear 36, and the retaining ring 10 abuts against the second drive member 34 and the cover 43 along the length direction of the drive shaft 32.

[0073] refer to Figures 1-3 According to some embodiments of the present invention, the cleaning module 100 further includes a traction rope 5, a second transmission member 34 being a winding reel, one end of the traction rope 5 being connected to the second transmission member 34 so that a portion of the traction rope 5 can be wound around the second transmission member 34, and the other end of the traction rope 5 being connected to the lifting frame 21. A support portion 6 is formed on the fixing frame 1, and the portion of the traction rope 5 located between its two ends is supported on the support portion 6, and the height of the support portion 6 is always higher than the two ends of the traction rope 5. Specifically, when the drive motor 31 rotates in the forward direction, the second transmission member 34 rotates to wind the traction rope 5 around itself; when the drive motor 31 rotates in the reverse direction, the second transmission member 34 releases the traction rope 5.

[0074] By including a traction rope 5 in the cleaning module 100 and a winding wheel in the second transmission member 34, one end of the traction rope 5 is connected to the second transmission member 34, and the other end of the traction rope 5 is connected to the lifting frame 21. The portion of the traction rope 5 located between its two ends is supported by a support portion 6 on the fixed frame 1. The arrangement of the traction rope 5 and the support portion 6 enables effective transmission between the second transmission member 34 and the lifting frame 21. The support portion 6 provides support for the traction rope 5 and keeps the traction rope 5 taut. As the traction rope 5 winds around the second transmission member 34, the two ends of the traction rope 5 can exert an upward force on the lifting mechanism 2 under the support of the support portion 6, so that the lifting mechanism 2 moves upward relative to the fixed frame 1.

[0075] By driving the motor 31 to rotate in both directions and coordinating with the winding and releasing of the traction rope 5, the second transmission component 34 can stably drive the lifting frame 21 to move upward and allow the lifting frame 21 to descend smoothly under the action of gravity. In addition, the traction rope 5, as a transmission component, has a simple structure and requires less installation space, which is beneficial for optimizing the spatial layout of the cleaning module 100.

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

[0077] refer to Figures 1-2 According to some optional embodiments of the present invention, a support limiting groove 61 is formed on the top of the support portion 6. The traction rope 5 is accommodated in the support limiting groove 61 and is movable along the extending direction of the support limiting groove 61. The height of the bottom wall of the support limiting groove 61 is always higher than the two ends of the traction rope 5. By forming a support limiting groove 61 on the top of the support portion 6 and accommodating the traction rope 5 in the support limiting groove 61 and allowing it to move along the extending direction of the support limiting groove 61, the support limiting groove 61 provides both limiting and guiding functions for the traction rope 5.

[0078] refer to Figures 1-2 According to some optional embodiments of the present invention, a traction sleeve 7 is further included, in which the traction rope 5 is threaded, and the traction sleeve 7 is accommodated within the support limiting groove 61. By providing the traction sleeve 7 accommodated within the support limiting groove 61 and threading the traction rope 5 through the traction sleeve 7, the traction sleeve 7 can further limit and guide the traction rope 5, and the traction sleeve 7 can also provide a protective function to reduce the mutual friction between the traction rope 5 and the support limiting groove 61.

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

[0080] refer to Figures 1-2According to some optional embodiments of the present invention, the support limiting groove 61 includes a first groove segment 611, a second groove segment 612 and a third groove segment 613 arranged in parallel along the extension direction of the support limiting groove 61, and the traction sleeve 7 includes a first tube body 71, a second tube body 72 and a third tube body 73 connected in sequence, the first tube body 71 and the third tube body 73 are respectively fixed in the first groove segment 611 and the third groove segment 613, and the second tube body 72 is accommodated in the second groove segment 612. By making the support limiting groove 61 include a first groove segment 611, a second groove segment 612, and a third groove segment 613, and making the traction sleeve 7 include a first tube body 71, a second tube body 72, and a third tube body 73, and fixing the first tube body 71 and the third tube body 73 respectively in the first groove segment 611 and the third groove segment 613, it is beneficial for the traction sleeve 7 to be stably supported on the support part 6, and it can prevent the traction rope 5 from causing the traction sleeve 7 to move randomly during the movement of the traction rope 5 relative to the support limiting groove 61.

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

[0082] refer to Figures 1-3 According to some optional embodiments of the present invention, the lifting frame 21 is provided with a fixed limiting part 8, and a through hole 81 is formed on the fixed limiting part 8. The other end of the traction rope 5 passes 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 coming off the through hole 81. By providing a fixed limiting part 8 with a through hole 81 on the lifting frame 21, the other end of the traction rope 5 can pass through the through hole 81. By providing an anti-detachment block 9 at the other end of the traction rope 5 and placing the anti-detachment block 9 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 part 8. Through the contact action between the anti-detachment block 9 and the fixed limiting part 8, the power is 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] refer to Figures 1-3According to some optional embodiments of the present invention, the fixing frame 1 is mounted on the upper part of the lifting frame 21. The fixing frame 1 has a first opening 11 and a second opening 12, which are located on both sides of the support part 6. The first opening 11 is used to avoid the fixing limiting part 8, and the second opening 12 is used to avoid the second transmission member 34. By forming the first opening 11 to avoid the fixing limiting part 8 and the second opening 12 to avoid 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 fixing limiting part 8 through the first opening 11, and to facilitate the maintenance of its connection relationship. It is also convenient to connect one end of the traction rope 5 to the second transmission member 34 through the second opening 12, and to facilitate the maintenance of its connection relationship.

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

[0085] The cam contacts the side of the movable cutter opposite to the fixed cutter, and the reset element can be a spring connecting the fixed and movable cutters. Thus, when the cam drives the movable cutter towards the fixed cutter, the spring is compressed, and the fixed and movable cutters cooperate to complete the cutting action. When the cam moves away from the movable cutter, the spring returns from its compressed state to its natural extension state. During this process, the spring drives the movable cutter away from the fixed cutter, opening the cutting slit between the two cutters and preparing for the next cutting action. Therefore, as the cam rotates with the drive shaft 32, the movable cutter reciprocates relative to the fixed cutter under the combined action of the cam and the reset element, thus performing a cutting action on the foreign matter wrapped around the roller brush assembly at a fixed frequency.

[0086] Optionally, the reset element can also be a first magnet and a second magnet respectively disposed on the fixed cutter and the movable cutter, wherein 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 movable cutter, the repulsive magnetic force between the first magnet and the second magnet can cause the movable cutter to move away from the fixed cutter, thereby achieving the purpose of opening the cutting gap between the fixed cutter and the movable cutter.

[0087] According to a second aspect of the present invention, a cleaning device includes: a device body and the cleaning module 100 described above, wherein a mounting bracket 1 of the cleaning module 100 is fixed to the device body.

[0088] According to the cleaning equipment of the present invention, by setting up the cleaning module 100, the cleaning module 100 is provided with a transmission shaft 32 connected to the drive motor 31, and a first transmission member 33 and a selection transmission member 35 respectively sleeved at both ends of the transmission shaft 32 in the length direction. A second transmission member 34 flexibly connected to the lifting frame 21 is sleeved on the outer periphery of the selection transmission member 35. This allows the drive motor 31 to drive the cutting component 23 to move through the first transmission member 33, and also to drive the selection transmission member 35 to rotate when the drive motor 31 rotates in the forward direction, so as to drive the lifting frame 21 to move upward through the second transmission member 34. This allows the cleaning component 22 provided on the lifting frame 21 to move upward relative to the working surface and separate from the working surface. This eliminates the need to set up a separate drive motor 31 for driving the lifting mechanism 2 to move upward and drive the cleaning component 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the cleaning module 100 easy to assemble, and reducing the cost of the cleaning module 100. Furthermore, it can simplify the structure of the cleaning equipment, making the cleaning equipment easy to assemble and reducing the cost of the cleaning equipment.

[0089] In addition, by fitting a selective transmission member 35 at one end of the transmission shaft 32, when the drive motor 31 rotates in the forward direction, the transmission shaft 32 can transmit power to the second transmission member 34 through the selective transmission member 35. When the drive motor 31 rotates in the reverse direction, the selective transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, the drive motor 31 can be controlled to drive the cutting component 23 to move or simultaneously drive the cutting component 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, which makes the structure of the drive mechanism simple. This also helps to simplify the structure of the cleaning module 100 and makes the assembly of the cleaning module 100 easier. Furthermore, it can also simplify the structure of the cleaning equipment and make the assembly of the cleaning equipment easier.

[0090] A cleaning system according to a third aspect of the present invention includes: the cleaning device described above and a cleaning base station, wherein the cleaning device is adapted to cooperate with the cleaning base station, the cleaning base station is used to clean the cleaning device, and the cleaning base station can also be used to charge the cleaning device. For example, the cleaning base station is used to clean the cleaning device; or the cleaning base station is used to charge the cleaning device; or the cleaning base station can be used to both clean and charge the cleaning device.

[0091] According to the cleaning system of the present invention, by setting up the cleaning equipment described above, the cleaning module 100 of the cleaning equipment is provided with a transmission shaft 32 connected to the drive motor 31, and a first transmission member 33 and a selection transmission member 35 respectively sleeved at both ends of the transmission shaft 32 in the length direction. A second transmission member 34 flexibly connected to the lifting frame 21 is sleeved on the outer periphery of the selection transmission member 35. This allows the drive motor 31 to drive the cutting component 23 to move through the first transmission member 33, and also to drive the selection transmission member 35 to rotate when the drive motor 31 rotates in the forward direction, so as to drive the lifting frame 21 to move upward through the second transmission member 34. This allows the cleaning component 22 provided on the lifting frame 21 to move upward relative to the working surface and separate from the working surface. This eliminates the need to set up a separate drive motor 31 for driving the lifting mechanism 2 to move upward and drive the cleaning component 22 to move upward, which is beneficial to simplifying the structure of the cleaning module 100, making the cleaning module 100 easier to assemble, and reducing the cost of the cleaning module 100. Furthermore, it can simplify the structure of the cleaning system, making the cleaning system easier to assemble, and reducing the cost of the cleaning equipment.

[0092] In addition, by fitting a selective transmission member 35 at one end of the transmission shaft 32, when the drive motor 31 rotates in the forward direction, the transmission shaft 32 can transmit power to the second transmission member 34 through the selective transmission member 35. When the drive motor 31 rotates in the reverse direction, the selective transmission member 35 will not transmit the force from the transmission shaft 32 to the second transmission member 34. In this way, the drive motor 31 can be controlled to drive the cutting component 23 to move or simultaneously drive the cutting component 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, which makes the structure of the drive mechanism simple. This also helps to simplify the structure of the cleaning module 100 and makes the assembly of the cleaning module 100 easier. Furthermore, it can also simplify the structure of the cleaning system and make the assembly of the cleaning system easier.

[0096] The first transmission component 33 is transmissionably connected to the cutting assembly 23 to drive the cutting assembly 23 to move.

When the drive motor 31 rotates in the forward direction, the transmission shaft 32 and the second transmission component 34 are transmission connected, and the second transmission component 34 drives the lifting frame 21 to move upward. When the drive motor 31 rotates in the reverse direction, the transmission shaft 32 and the second transmission component 34 are disconnected, and the lifting frame 21 moves downward under its own gravity.

[0099] A support portion 6 is formed on the fixed frame 1. A support limiting groove 61 is formed on the top of the support portion 6. The traction rope 5 is accommodated in the support limiting groove 61 and can move along the extension direction of the support limiting groove 61. The portion of the traction rope 5 located between the two ends of the traction rope 5 is supported by the support portion 6.

The first opening 11 is used to avoid the fixing limiting part 8, and the second opening 12 is used to avoid the second transmission member 34.

[0102] When the drive motor 31 rotates in the forward direction, the power of the drive motor 31 can be transmitted to the second transmission member 34 through the selective transmission member 35.
