[0052] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0053] The cleaning device and cleaning system according to the embodiments of the present application are described below with reference to FIG1 to FIG9 .

[0054] 1 to 9 , the cleaning device includes a device body 100 , a cleaning assembly 22 and a driving assembly 400 . The cleaning assembly 22 and the driving assembly 400 are disposed on the device body 100 . The driving assembly 400 is used to drive the cleaning assembly 22 to rise and fall relative to the device body 100 .

[0055] For example, when the cleaning device is performing a cleaning task and encounters an interfering object on the cleaning surface, the cleaning assembly 22 can be lifted upward relative to the device body 100 to avoid the interfering object.

[0056] For example, when the cleaning component 22 needs to be used, the driving component 400 drives the cleaning component 22 to descend to the falling position, at which time the cleaning component 22 can clean the work surface. When the cleaning component 22 is not needed, the driving component 400 drives the cleaning component 22 to rise to the lifting position.

[0057] According to the cleaning device of the embodiment of the present application, the driving component 400 is used to drive the cleaning component 22 to rise and fall relative to the device body 100. When the cleaning device cleans the working surface, the cleaning component 22 can avoid water stains, stains, interference objects, etc. on the working surface by lifting upward relative to the device body 100, thereby avoiding the cleaning component 22 from causing secondary contamination to the working surface, or avoiding collision and interference between the cleaning component 22 and interference objects protruding from the working surface.

[0058] In addition, when the cleaning assembly 22 does not need to clean the working surface, the cleaning assembly 22 can also move upward relative to the equipment body 100 to store the cleaning assembly 22.

[0059] 1-5 , according to some embodiments of the present application, the cleaning device includes a cleaning module 1000 , which includes a fixed frame 1 , a lifting mechanism 2 , and a driving assembly 400 . The driving assembly 400 can drive the lifting mechanism 2 to move up and down relative to the fixed frame 1 .

[0060] The lifting mechanism 2 includes a lifting frame 21, a cleaning assembly 22, and a cutting assembly 23 mounted on the lifting frame 21. The lifting frame 21 is 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 work surface to clean it, and the cutting assembly 23 is used to cut away debris attached to the cleaning assembly 22. For example, the cutting assembly 23 has a cutting opening that extends toward the cleaning assembly 22. Alternatively, the work surface can be a floor, carpet, or the like.

[0061] Optionally, the fixing frame 1 is flexibly connected to the lifting frame 21 , which can effectively absorb the impact, vibration, etc. generated during the movement of the lifting frame 21 relative to the fixing frame 1 .

[0062] By providing the cutting component 23 , the cutting component 23 can be used to clean the garbage attached to the cleaning component 22 , so that the cleaning component 22 itself can be kept clean, which is beneficial to improving the cleaning effect of the cleaning component 22 .

[0063] With reference to Figures 1-5, according to some optional embodiments of the present application, the drive assembly 400 is disposed on the lifting frame 21 and includes a motor 421, a transmission shaft 32, a first transmission member 33, a second transmission member 34, and a selector transmission member 35. The motor 421 is connected to the transmission shaft 32 to drive the transmission shaft 32 to rotate. The first transmission member 33 and the selector transmission member 35 are respectively sleeved on both ends of the transmission shaft 32 in the longitudinal direction. The second transmission member 34 is sleeved on the outer periphery of the selector transmission member 35 and is fixed relative to the selector transmission member 35. The motor 421 outputs driving force and transmits it to the first transmission member 33 and the selector transmission member 35 through the transmission shaft 32. When the driving direction of the motor 421 is consistent with the transmission direction of the selector transmission member 35, the selector transmission member 35 drives the second transmission member 34 to move.

[0064] The first transmission member 33 is in transmission connection with the cutting assembly 23 to drive the cutting assembly 23 to move, and the second transmission member 34 is connected to the lifting frame 21. For example, at least a portion of the cutting assembly 23 can move horizontally relative to the lifting frame 21 to cut garbage attached to the cleaning assembly 22.

[0065] Optionally, the second transmission member 34 is flexibly connected to the lifting frame 21 , which can effectively absorb the impact, vibration, etc. generated when the second transmission member 34 drives the lifting frame 21 to move relative to the fixed frame 1.

[0066] By providing a transmission shaft 32 connected to the motor 421 and respectively arranging a first transmission member 33 and a selection transmission member 35 at both ends in the length direction of the transmission shaft 32, and arranging a second transmission member 34 connected to the lifting frame 21 on the periphery of the selection transmission member 35, the motor 421 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 motor 421 rotates forward to drive the lifting frame 21 to move upward through the second transmission member 34, so that the cleaning assembly 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 for providing a motor 421 separately 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 1000, making the cleaning module 1000 easy to assemble, and reducing the cost of the cleaning module 1000.

[0067] With reference to Figures 1-5, according to some optional embodiments of the present application, when the motor 421 rotates in the forward direction, the drive shaft 32 is connected to the second transmission member 34. The drive shaft 32 transmits power to the second transmission member 34 via the selection transmission member 35. The second transmission member 34 drives the lifting frame 21 upward, allowing the cleaning assembly 22 mounted on the lifting frame 21 to move upward relative to the work surface and separate from the work surface. When the motor 421 rotates in the reverse direction, the drive shaft 32 is disconnected from the second transmission member 34. The selection transmission member 35 cannot transmit power from the drive shaft 32 to the second transmission member 34. The lifting frame 21 moves downward under its own gravity, allowing the cleaning assembly 22 to clean the work surface normally. When the motor 421 rotates in the forward direction, the drive assembly 400 can simultaneously drive the cutting assembly 23 and the lifting frame 21. When the motor 421 rotates in the reverse direction, the drive assembly 400 can also drive the cutting assembly 23 normally, and the cleaning assembly 22 can also clean the work surface normally under the action of gravity.

[0068] By sleeved with a selection transmission member 35 at one end of the transmission shaft 32, when the motor 421 rotates forward, the transmission shaft 32 can transmit power to the second transmission member 34 through the selection transmission member 35, and when the motor 421 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 motor 421 to drive the cutting assembly 23 to move or simultaneously drive the cutting assembly 23 to move and the lifting mechanism 2 to move upward according to the working needs of the cleaning module 1000. The transmission structure between the transmission shaft 32 and the second transmission member 34 is simple, thereby making the structure of the driving assembly 400 simple, which is also conducive to simplifying the structure of the cleaning module 1000 and making the assembly of the cleaning module 1000 easy.

[0069] Optionally, the cleaning component 22 may be a roller brush component or a mopping component; for example, the cleaning component 22 is a roller brush component, and the first transmission member 33 is connected to the cutting component 23 to drive the cutting component 23 to cut foreign matter entangled on the roller brush component, such as hair.

[0070] For example, when the motor 421 rotates forward, the motor 421 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.

[0071] For example, when the motor 421 rotates in the opposite direction, the motor 421 drives the first transmission member 33 to rotate through the transmission shaft 32, and 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, 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.

[0072] For example, the cleaning component 22 is a roller brush component. When the cleaning module 1000 is applied to the cleaning device and the cleaning device is performing the mopping function, in order to prevent the roller brush component from causing secondary pollution to the ground after mopping, the cleaning device can control the motor 421 to rotate in the forward direction. The motor 421 transmits power to the selection transmission member 35 through the transmission shaft 32. The selection transmission member 35 drives the second transmission member 34 fixed relatively to it to rotate, and the second transmission member 34 drives the lifting frame 21 to move upward, so that the lifting frame 21 drives the roller brush assembly provided thereon to move upward and separate from the ground.

[0073] 4-5 , according to some embodiments of the present application, the transmission member 35 is selected as a one-way bearing. By making the transmission member 35 a one-way bearing, the one-way bearing has a simple structure and can reliably and stably transmit torque in one direction. Therefore, when the motor 421 rotates in the forward direction, the transmission member 35 can reliably and stably transmit power to the second transmission member 34. When the motor 421 rotates in the reverse direction, the transmission member 35 can effectively prevent the transmission member 35 from transmitting power to the second transmission member 34, thereby preventing interference with the normal operation of the cleaning module 1000 as a whole.

[0074] 4 , according to some optional embodiments of the present application, one of the outer circumferential wall of the transmission member 35 and the inner circumferential 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.

[0075] For example, a limiting protrusion is provided on the outer peripheral wall of the selection transmission member 35, and a limiting groove is provided on the inner peripheral wall of the second transmission member 34. The limiting protrusion is accommodated in the limiting groove to relatively fix the selection transmission member 35 and the second transmission member 34.

[0076] For example, a limiting groove is provided on the outer peripheral wall of the selection transmission member 35, and a limiting protrusion is provided on the inner peripheral wall of the second transmission member 34. The limiting protrusion is accommodated in the limiting groove to relatively fix the selection transmission member 35 and the second transmission member 34.

[0077] By providing a limiting protrusion on one of the outer peripheral wall of the selection transmission member 35 and the inner peripheral wall of the second transmission member 34 and providing a limiting groove on the other, and accommodating the limiting protrusion in the limiting groove, the structure of the limiting groove and the limiting protrusion is simple, thereby making the structure of the selection transmission member 35 and the second transmission member 34 simple and the matching transmission relationship between the selection transmission member 35 and the second transmission member 34 simple.

[0078] 4 , according to some embodiments of the present application, the drive assembly 400 further includes a worm gear transmission mechanism, which 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. The worm 37 is provided at the output end of the motor 421. Optionally, the output end of the motor 421 and the worm 37 are coaxially connected.

[0079] By setting up a worm gear transmission mechanism, the worm wheel 36 and worm 37 mechanism can stably transmit the power of the motor 421 to the transmission shaft 32. When the motor 421 rotates forward, the transmission of the worm wheel 36 and worm 37 can stably and safely drive the lifting frame 21 so that the lifting frame 21 can rise smoothly.

[0080] Referring to Figures 4-5, according to some optional embodiments of the present application, the cleaning module 1000 also includes a box body 4 having a accommodating cavity, the transmission shaft 32 is rotatably provided in the accommodating cavity, the box body 4 includes a first box body 41, a second box body 42 and a protective cover 43 arranged and connected in sequence along the length direction of the transmission shaft 32, the accommodating cavity includes a first accommodating cavity 44 and a second accommodating cavity 45 arranged along the first direction and connected, the first box body 41 and the second box body 42 are detachably connected and define a first accommodating cavity 44, the second box body 42 and the protective cover 43 are detachably connected and define a second accommodating cavity 45, the worm gear 36 and at least part of the first transmission member 33 are accommodated in the first accommodating cavity 44, and the transmission member 35 and the second transmission member 34 are selectively accommodated in the second accommodating cavity 45.

[0081] For example, the assembly process of the cleaning module 1000 may include the following steps:

[0082] First, the first transmission member 33 and the worm gear 36 are mounted on the transmission shaft 32; then, the transmission shaft 32 on which the first transmission member 33 and the worm gear 36 are mounted is first assembled to the first box body 41, and the second box body 42 is connected to the first box body 41 to define a first accommodating cavity 44; then, the selection transmission member 35 is mounted on the other end of the transmission shaft 32, and the second transmission member 34 is mounted on the outer periphery of the selection transmission member 35; then, the protective cover 43 is connected to the second box body 42 to define a second accommodating cavity 45.

[0083] By forming 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 the first box body 41 and the second box body 42 define a first accommodating chamber 44, and the second box body 42 and the third box body 4 define a second accommodating chamber 45, during the assembly process of the cleaning module 1000, the worm gear 36 and the first transmission member 33 can be first accommodated in the first accommodating chamber 44, and then the selection transmission member 35 and the second transmission member 34 in the second accommodating chamber 45 can be installed. The second box body 42 can form a limiting effect on the components in the first accommodating chamber 44 to prevent them from affecting the assembly of the components in the second accommodating chamber 45, thereby helping to improve assembly efficiency; in addition, when it is necessary to inspect, maintain or replace the components in the first accommodating chamber 44 or the second accommodating chamber 45, there is no need to disassemble the entire box body 4, thereby facilitating the inspection, maintenance and replacement of the components in the box body 4.

[0084] Optionally, the motor 421 is arranged outside the box body 4 and can be connected to the box body 4, and the rotation axis of the output end of the motor 421 intersects with the axial direction of the transmission shaft 32, for example, the rotation axis of the output end of the motor 421 is perpendicular to the axial direction of the transmission shaft 32.

[0085] Optionally, the cleaning module 1000 further includes a clamping ring 10 , which is clamped on the outer peripheral side of the transmission shaft 32 and located on the side of the second transmission member 34 away from the worm gear 36 , and the clamping ring 10 abuts between the second transmission member 34 and the protective cover 43 along the length direction of the transmission shaft 32 .

[0086] 1-3 , according to some embodiments of the present application, the cleaning module 1000 further includes a traction rope 5, a second transmission member 34 being a winding wheel, 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 fixed frame 1, and a portion of the traction rope 5 located between the two ends of the traction rope 5 is supported by the support portion 6, and the height of the support portion 6 is always higher than the two ends of the traction rope 5. When the motor 421 rotates forward, the second transmission member 34 rotates to wind the traction rope 5 around the second transmission member 34, and when the motor 421 rotates reversely, the second transmission member 34 releases the traction rope 5.

[0087] By making the cleaning module 1000 include a traction rope 5 and making the second transmission member 34 a winding wheel, one end of the traction rope 5 is connected to the second transmission member 34, the other end of the traction rope 5 is connected to the lifting frame 21, and the part of the traction rope 5 located between the two ends of the traction rope 5 is supported by the support part 6 on the fixed frame 1, the arrangement of the traction rope 5 and the support part 6 realizes effective transmission between the second transmission member 34 and the lifting frame 21, and the support part 6 provides support for the traction rope 5 and keeps the traction rope 5 in a tensioned state, so that when the traction rope 5 is wound around the second transmission member 34, the traction rope 5 can exert an upward force on the lifting mechanism 2 under the support of the support part 6, so that the lifting mechanism 2 moves upward relative to the fixed frame 1.

[0088] Through the forward and reverse rotation of the motor 421, and in conjunction with the winding and releasing of the traction rope 5, the second transmission member 34 can stably drive the lifting frame 21 to move upward, and the lifting frame 21 can be smoothly lowered under the action of gravity; in addition, the traction rope 5 as a transmission component has a simple structure and requires a small installation space, which is conducive to optimizing the spatial layout of the cleaning module 1000.

[0089] For example, the cleaning component 22 is a roller brush component. When the cleaning module 1000 is applied to the cleaning device and the cleaning device is performing the mopping function, in order to prevent the roller brush component from causing secondary pollution to the ground after mopping, the cleaning device can control the motor 421 to rotate in the forward direction. The motor 421 transmits power to the selection transmission member 35 through the transmission shaft 32. The selection transmission member 35 drives the second transmission member 34 fixed relatively thereto to rotate. The second transmission member 34 rotates to wrap the traction rope 5 around the second transmission member 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 assembly reaches a preset height from the ground, the motor 421 stops rotating, so that the roller brush assembly can be kept at the preset height from the ground; and when it is necessary to control the roller brush assembly to fall to the ground, the motor 421 can be controlled to rotate in the reverse direction, and the lifting mechanism 2 falls under the action of gravity until it contacts the ground.

[0090] With reference to Figures 1 and 2, according to some optional embodiments of the present application, a support limiting groove 61 is formed at the top of the support portion 6. The traction rope 5 is accommodated in the support limiting groove 61 and is movable along the extension direction of the support limiting groove 61. The bottom wall of the support limiting groove 61 is always higher than the ends of the traction rope 5. By forming the support limiting groove 61 at the top of the support portion 6 and allowing the traction rope 5 to be accommodated in the support limiting groove 61 and movable along the extension direction of the support limiting groove 61, the support limiting groove 61 has a limiting and guiding effect on the traction rope 5.

[0091] 1 and 2 , according to some optional embodiments of the present application, a traction sleeve 7 is further included, through which the traction rope 5 is passed, and the traction sleeve 7 is accommodated in the support limiting groove 61. By providing the traction sleeve 7 accommodated in the support limiting groove 61 and passing 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.

[0092] Optionally, the traction sleeve 7 is a hose; optionally, the traction rope 5 is a steel wire rope.

[0093] Referring to Figures 1-2, according to some optional embodiments of the present application, the support limit groove 61 includes a first groove section 611, a second groove section 612 and a third groove section 613 arranged in parallel along the extension direction of the support limit 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 section 611 and the third groove section 613, and the second tube body 72 is accommodated in the second groove section 612. By making the support limit 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 tube body 71, the second tube body 72 and the third tube body 73, and fixing the first tube body 71 and the third tube body 73 in the first groove section 611 and the third groove section 613 respectively, it is beneficial to stably support the traction sleeve 7 on the support part 6, and can prevent the traction rope 5 from driving the traction sleeve 7 to move at will during the movement of the traction rope 5 relative to the support limit groove 61.

[0094] Optionally, the first slot segment 611 , the second slot segment 612 and the third slot segment 613 are spaced apart from each other.

[0095] With reference to Figures 1-3, according to some optional embodiments of the present application, a fixed stopper 8 is provided on the lifting frame 21. The fixed stopper 8 has a through hole 81 formed therein. The other end of the traction rope 5 is passed through the through hole 81. The other end of the traction rope 5 is provided with an anti-slip block 9. The anti-slip block 9 is located below the through hole 81 and is used to prevent the other end of the traction rope 5 from slipping upward through the through hole 81. By providing the fixed stopper 8 with the through hole 81 on the lifting frame 21, so that the other end of the traction rope 5 can be passed through the through hole 81, and by providing the anti-slip block 9 at the other end of the traction rope 5 and positioning the anti-slip 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 until it contacts the fixed stopper 8. The contact between the anti-slip block 9 and the fixed stopper 8 stably transmits power to the lifting frame 21, so that the lifting frame 21 can stably move upward under the action of the traction rope 5.

[0096] 1-3 , according to some optional embodiments of the present application, a fixing frame 1 is provided over the upper portion of a lifting frame 21. A first opening 11 and a second opening 12 are formed on the fixing frame 1. The first opening 11 and the second opening 12 are located on either side of the support portion 6. The first opening 11 is used to avoid the fixed stop portion 8, and the second opening 12 is used to avoid the second transmission member 34. By forming the first opening 11 for avoiding the fixed stop portion 8 and the second 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 stop portion 8 through the first opening 11, and to facilitate maintenance of the 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 maintenance of the connection relationship.

[0097] According to some optional embodiments of the present application, the rotation axis of the first transmission member 33 extends along a first direction, and at least a portion of the cutting assembly 23 performs reciprocating linear motion in a horizontal direction relative to the cleaning assembly 22. 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, forming a cutting opening between the fixed cutter and the movable cutter. The cam contacts or is connected to 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.

[0098] The cam contacts the side of the movable cutter facing away from the fixed cutter, and the reset member can be a spring connected between the fixed cutter and the movable cutter. Thus, when the cam drives the movable cutter toward the fixed cutter, the spring is compressed, and the fixed and movable cutters cooperate to complete the shearing action. When the cam moves away from the movable cutter, the spring returns from the compressed state to its naturally extended state. During this process, the spring drives the movable cutter away from the fixed cutter, opening the cutting opening between the fixed and movable cutters and preparing for the next cutting action. Thus, 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 member, thereby cutting foreign matter entangled in the roller brush assembly at a fixed frequency.

[0099] Alternatively, the reset element may be a first magnet and a second magnet, respectively disposed on the fixed cutter and the movable cutter, with the end of the first magnet facing the second magnet and the end of the second magnet facing the first magnet having the same magnetic pole. Thus, when the cam moves away from the movable cutter, the repulsive magnetic force between the first and second magnets causes the movable cutter to move away from the fixed cutter, thereby opening the cutting opening between the fixed and movable cutters.

[0100] As shown in Figure 6, according to the cleaning device of the embodiment of the present application, the cleaning device also includes a dust box 200, the cleaning assembly includes a roller brush assembly 300, the dust box 200, the roller brush assembly 300 and the drive assembly 400 are installed on the device body 100, the device body includes a shell, and a gap 130 is provided between the bottom wall of the device body 100 and the dust box 200. The roller brush assembly 300 is located on one side of the dust box 200, and at least a portion of the drive assembly 400 is located in the gap 130. The drive assembly 400 is used to drive the roller brush assembly 300 to rise and fall relative to the device body 100.

[0101] The roller brush assembly 300 and the drive assembly 400 are installed on the device body 100, and the drive assembly 400 is connected to the roller brush assembly 300. For example, when the roller brush assembly 300 needs to be used, the drive assembly 400 drives the roller brush assembly 300 to descend to the falling position. At this time, the roller brush assembly 300 can clean the surface to be cleaned. When the roller brush assembly 300 is not needed, the drive assembly 400 drives the roller brush assembly 300 to rise to the lifting position.

[0102] A dust collection box 200 is provided on one side of the roller brush assembly 300 , and dust, garbage, etc. cleaned by the roller brush assembly 300 can be sucked into the dust collection box 200 .

[0103] A gap 130 is usually provided between the bottom of the dust box 200 and the bottom wall of the device body 100. This gap 130 is used to avoid other components in the cleaning device. Therefore, this gap 130 will cause a waste of space. The drive assembly 400 is installed in the gap 130 between the dust box 200 and the device body 100, and the drive assembly 400 is installed using the original gap. This can provide space for the installation of other components, thereby improving the space utilization rate inside the cleaning device. By reasonably utilizing the internal space of the cleaning device, the difficulty of the installation layout inside the cleaning device can be reduced. While ensuring that the volume of the cleaning device remains basically unchanged, more components can be installed to improve the functionality of the cleaning device.

[0104] 6 and 8 , in some embodiments, optionally, the driving assembly 400 includes: a movable portion 410 , which cooperates with the roller brush assembly 300 to drive the roller brush assembly 300 to move up and down, and the movement direction of the movable portion 410 is set in the same direction as the length direction of the gap 130 .

[0105] The movable part 410 can move relative to the device body 100. The device body includes a shell. The movable part 410 can move relative to the shell, and the movable part 410 is used to drive the roller brush assembly 300 to move, so that the movable part 410 can drive the roller brush assembly 300 to rise and fall relative to the device body 100.

[0106] The movable part 410 moves along the length direction of the gap 130. Therefore, when the movable part 410 drives the roller brush assembly 300 to move, the movable part 410 occupies the space along the length direction of the gap 130. In this case, there is no need to increase the size of the gap 130 for the movement of the movable part 410, so that the original space of the gap 130 can be used to install the movable part 410 and provide space for the movement of the movable part 410, thereby improving the space utilization inside the cleaning equipment and realizing the driving function of the roller brush assembly 300 while ensuring that the volume of the cleaning equipment remains basically unchanged.

[0107] 6 , 8 and 9 , in some embodiments, optionally, the driving assembly 400 further includes: a driving portion 420, the driving portion 420 being connected to the movable portion 410, the driving portion 420 being used to drive the movable portion 410 to move between a first position and a second position, when the movable portion 410 is in the first position, the roller brush assembly 300 is in a raised position, and when the movable portion 410 is in the second position, the roller brush assembly 300 is in a lowered position.

[0108] The driving portion 420 and the movable portion 410 are both installed within the gap 130. The driving portion 420 is used to drive the movable portion 410 to move within the gap 130. The movable portion 410 is used to cooperate with the roller brush assembly 300. When the movable portion 410 moves from the second position to the first position, the movable portion 410 pushes the roller brush assembly 300 upward. When the movable portion 410 moves to the first position, the roller brush assembly 300 moves to the raised position, at which point the roller brush assembly 300 is separated from the surface to be cleaned. When the movable portion 410 moves from the first position to the second position, since the movable portion 410 no longer pushes the roller brush assembly 300, the roller brush assembly 300 is able to fall freely under the action of gravity. When the movable portion 410 moves to the second position, the roller brush assembly 300 moves to the lowered position, at which point the roller brush assembly 300 contacts the surface to be cleaned.

[0109] The horizontal linear motion of the movable portion 410 can be converted into the lifting motion of the roller brush assembly 300. Through the above driving method, the space in the gap 130 can be reasonably utilized, and the driving function of the roller brush assembly 300 can be realized without changing the size of the gap 130.

[0110] 8 and 9 , in some embodiments, optionally, a first inclined surface 310 is provided on the roller brush assembly 300 , and the movable portion 410 can move along the first inclined surface 310 so that the movable portion 410 pushes the roller brush assembly 300 to rise and fall relative to the device body 100 .

[0111] A first inclined surface 310 is machined and formed on the roller brush assembly 300. The first inclined surface 310 is inclined relative to the bottom wall of the device body 100. When the driving part 420 drives the movable part 410 to move, the movable part 410 cooperates with the first inclined surface 310, so that the movable part 410 can drive the roller brush assembly 300 to rise and fall relative to the device body 100 through the first inclined surface 310.

[0112] Specifically, the movable portion 410 is movable along the length of the gap 130. When the movable portion 410 contacts the first inclined surface 310, the movable portion 410 is movable along the first inclined surface 310. As the movable portion 410 moves, the movable portion 410 pushes the first inclined surface 310, causing the roller brush assembly 300 to rise relative to the device body 100 under the push of the movable portion 410. When the movable portion 410 moves in the opposite direction, the movable portion 410 no longer pushes the first inclined surface 310, and the roller brush assembly 300 falls due to gravity. The interaction between the movable portion 410 and the first inclined surface 310 allows the roller brush assembly 300 to rise smoothly, improving the coordination stability between the drive assembly 400 and the roller brush assembly 300.

[0113] 8 and 9 , in some embodiments, optionally, a second inclined surface 411 is provided on the movable portion 410 , and the second inclined surface 411 has the same slope as the first inclined surface 310 , and the second inclined surface 411 can move along the first inclined surface 310 so that the movable portion 410 pushes the roller brush assembly 300 .

[0114] The device body includes a shell, and a second inclined surface 411 is formed on the movable part 410. The second inclined surface 411 is inclined relative to the bottom wall of the shell 100. When the driving part 420 drives the movable part 410 to move, the second inclined surface 411 cooperates with the first inclined surface 310, so that the second inclined surface 411 drives the roller brush assembly 300 to rise and fall relative to the device body 100 through the first inclined surface 310.

[0115] When the second inclined surface 411 contacts the first inclined surface 310, as the movable portion 410 moves, the second inclined surface 411 pushes the first inclined surface 310, causing the roller brush assembly 300 to rise relative to the device body 100 under the push of the second inclined surface 411. The cooperation between the first inclined surface 310 and the second inclined surface 411 allows the drive assembly 400 to more smoothly drive the roller brush assembly 300 up and down, and it is less likely to cause jamming between the drive assembly 400 and the roller brush assembly 300, which helps to improve the functional stability of the cleaning device.

[0116] 7 , 8 and 9 , in some embodiments, optionally, the cleaning device further includes: a touch portion 500, a first detection switch 600 and a second detection switch 700, the touch portion 500 is connected to the movable portion 410, the first detection switch 600 and the second detection switch 700 are connected to the device body 100, the device body includes a shell, the first detection switch 600 and the second detection switch 700 are connected to the shell, when the touch portion 500 is located at the detection position of the first detection switch 600, the movable portion 410 is located at the first position, and when the touch portion 500 is located at the detection position of the second detection switch 700, the movable portion 410 is located at the second position.

[0117] A first detection switch 600 and a second detection switch 700 are installed on the device body 100, and a touch portion 500 is installed on the movable portion 410. When the movable portion 410 moves within the gap 130, the movable portion 410 drives the touch portion 500 to move. The first detection switch 600 and the second detection switch 700 are used to detect the position of the touch portion 500, thereby determining the position of the movable portion 410.

[0118] Specifically, when the movable portion 410 moves within the gap 130, if the touch portion 500 moves to the detection position of the first detection switch 600, it indicates that the movable portion 410 has moved to the first position, that is, the movable portion 410 has moved into position. At this time, the controller in the cleaning device controls the driving portion 420 to stop moving to prevent the movable portion 410 from continuing to move beyond the first position. If the touch portion 500 moves to the detection position of the second detection switch 700, it indicates that the movable portion 410 has moved to the second position, that is, the movable portion 410 has moved into position. At this time, the controller controls the driving portion 420 to stop moving to prevent the movable portion 410 from continuing to move beyond the second position.

[0119] The first position and the second position are two extreme positions set for the movable part 410. The movable part 410 can only move between the first position and the second position. By setting the first detection switch 600 and the second detection switch 700 to detect the position of the touch part 500, it can be ensured that the movable part 410 is docked at the first position or the second position, thereby ensuring the accuracy of the movement position of the movable part 410.

[0120] It should be noted that the detection position of the first detection switch 600 refers to the position where the first detection switch 600 can detect the touch portion 500. The detection position of the second detection switch 700 refers to the position where the second detection switch 700 can detect the touch portion 500.

[0121] 8 and 9 , in some embodiments, optionally, the driving portion 420 includes: a motor 421 and a screw rod 422 , the motor 421 is connected to the device body 100 , the screw rod 422 is connected to the motor 421 , the motor 421 is used to drive the screw rod 422 to rotate, and the movable portion 410 includes: a slider 412 , the slider 412 is connected to the screw rod 422 , and the slider 412 can slide along the axial direction of the screw rod 422 .

[0122] Motor 421 is mounted on device body 100 and fixed in position. Screw 422 is connected to the output shaft of motor 421, and motor 421 can drive screw 422 to rotate. Slider 412 is sleeved on screw 422 and can cooperate with screw 422. When screw 422 rotates, slider 412 moves along the axial direction of screw 422, forming a ball screw structure.

[0123] When the motor 421 is running, the slider 412 can reciprocate on the screw rod 422, so that the slider 412 can move to the first position or the second position. The second inclined surface 411 is provided on the slider 412. When the slider 412 moves along the screw rod 422, the second inclined surface 411 can move along the first inclined surface 310, thereby achieving the lifting and lowering of the roller brush assembly 300.

[0124] The touch part 500 is set on the slider 412. When the slider 412 moves along the screw rod 422, the slider 412 drives the touch part 500 to move. When the first detection switch 600 detects the touch part 500, the slider 412 moves to the first position. When the second detection switch 700 detects the touch part 500, the slider 412 moves to the second position.

[0125] In a possible application, the touch portion 500 and the slider 412 are integrally formed, or the touch portion 500 is fastened to the slider 412 by a fastening member such as a screw.

[0126] As shown in Figure 7, in some embodiments, optionally, the slider 412 includes: a sliding portion 413 and a pushing portion 414, the sliding portion 413 is connected to the screw rod 422, the pushing portion 414 is connected to the sliding portion 413, and the pushing portion 414 is used to push the roller brush assembly 300, and the pushing portion 414 extends along the axial direction of the screw rod 422.

[0127] The sliding portion 413 is sleeved onto the screw rod 422. When the screw rod 422 rotates, the sliding portion 413 can move axially along the screw rod 422. The pushing portion 414 is connected to the sliding portion 413. When the sliding portion 413 moves along the screw rod 422, the pushing portion 414 moves synchronously with the sliding portion 413. The second inclined surface 411 is provided on the pushing portion 414. When the pushing portion 414 moves, the second inclined surface 411 of the pushing portion 414 cooperates with the first inclined surface 310 of the roller brush assembly 300, thereby pushing the roller brush assembly 300.

[0128] The pushing portion 414 moves along the length direction of the gap 130. The larger the size of the pushing portion 414 along the length direction of the gap 130, the larger the contact area between the pushing portion 414 and the roller brush assembly 300, thereby improving the contact stability between the pushing portion 414 and the roller brush assembly 300 and improving the pushing stability of the roller brush assembly 300 by the pushing portion 414.

[0129] The pushing portion 414 extends along the axial direction of the screw rod 422, so that the second inclined surface 411 can extend along the axial direction of the screw rod 422, thereby increasing the contact area between the first inclined surface 310 and the second inclined surface 411, and improving the stability of the first inclined surface 310 and the second inclined surface 411 when they are matched.

[0130] Only the pushing portion 414 may be widened, while the width of the sliding portion 413 is still set to be smaller, which can reduce the weight and occupied space of the slider 412.

[0131] In a possible application, the slider 412 is T-shaped when viewed from above or below.

[0132] 8 and 9 , in some embodiments, optionally, the first detection switch 600 and the second detection switch 700 are located in the extending direction of the lead screw 422 .

[0133] The first detection switch 600 and the second detection switch 700 are located on one side of the lead screw 422 in the axial direction. That is, the first detection switch 600 and the second detection switch 700 are distributed along the axial direction of the lead screw 422 .

[0134] Slider 412 moves along the length of gap 130, so screw rod 422 extends along the length of gap 130, effectively utilizing the space in gap 130. The first detection switch 600 and the second detection switch 700 are positioned on one side of the screw rod 422 along the axial direction, so that the screw rod 422, the first detection switch 600, and the second detection switch 700 are distributed along the length of gap 130. This layout allows the installation positions of the first detection switch 600 and the second detection switch 700 to fully utilize the space in the length of gap 130, eliminating the need to increase the size of gap 130 for the first detection switch 600 and the second detection switch 700. Furthermore, the first detection switch 600 and the second detection switch 700 can fully utilize the space within gap 130, thereby improving the space utilization rate within the cleaning device. By rationally utilizing the internal space of the cleaning device, the difficulty of installation layout within the cleaning device can be reduced, and more components can be installed while maintaining a substantially unchanged volume of the cleaning device, thereby improving the functionality of the cleaning device.

[0135] As shown in FIG. 6 , in some embodiments, optionally, a mounting slot 140 is provided on the device body 100 , and at least a portion of the driving assembly 400 is located in the mounting slot 140 .

[0136] A gap 130 is provided between the bottom wall of the device body 100 and the dust collection box 200 , and a mounting groove 140 is formed in the gap 130 . For example, a portion of the bottom wall of the device body 100 is bent upward to form the mounting groove 140 .

[0137] At least a portion of the drive assembly 400 is installed in the installation groove 140. The installation groove 140 positions and limits the drive assembly 400, making it difficult for the drive assembly 400 to shake relative to the device body 100, thereby improving the installation stability of the drive assembly 400.

[0138] In a possible application, the first detection switch 600 and the second detection switch 700 are also located in the mounting groove 140 .

[0139] As shown in FIG. 7 , in some embodiments, optionally, the cleaning device further includes: a mopping assembly 800 connected to the device body 100 , the mopping assembly 800 being capable of rising and falling relative to the device body 100 , with a portion of the mopping assembly 800 being located within the gap 130 .

[0140] The mopping assembly 800 is installed on the device body 100, so that the cleaning device has the functions of sweeping and mopping the floor. The roller brush assembly 300 is used to sweep the surface to be cleaned, and the mopping assembly 800 is used to mop the surface to be cleaned.

[0141] The mopping assembly 800 is usually installed on one side of the roller brush assembly 300. When the mopping assembly 800 is installed, the structure for driving the mopping assembly 800 to move usually occupies the space between the bottom wall of the device body 100 and the dust box 200, thereby forming a gap 130 between the bottom wall of the device body 100 and the dust box 200, and the driving assembly 400 is installed in the gap 130. The space in the gap 130 is reasonably utilized to improve the space utilization rate inside the cleaning device. By reasonably utilizing the internal space of the cleaning device, the difficulty of installation layout inside the cleaning device can be reduced. While ensuring that the volume of the cleaning device remains basically unchanged, more components can be installed to improve the function of the cleaning device.

[0142] In a possible application, the mopping assembly 800 can be raised and lowered by driving a ball screw structure, or by driving a gear and rack structure.

[0143] In a possible embodiment, the device body 100 includes a bottom shell 110 and a middle frame 120, and the roller brush assembly 300 is located above the bottom shell 110 and below the dust box 200 and the middle frame 120, thereby eliminating space in front of the roller brush assembly 300.

[0144] The middle frame 120 is the design basis for the entire device's installation. The roller brush assembly 300 includes a roller brush 320 and a bracket 330. The bracket 330 is fixedly mounted above the middle frame 120, and the roller brush 320 is mounted on the bracket 330 and can rotate relative to the bracket 330. The bottom shell 110 is mounted below the middle frame 120 and serves as a fixing and decorative function. The motor 421 is fixedly mounted below the middle frame 120 and can drive the screw rod 422 to rotate. The slider 412 cooperates with the screw rod 422, and the slider 412 moves left and right along the screw rod 422. One end of the slider 412 contains a slope, namely the second inclined surface 411, which is used to cooperate with the first inclined surface 310 on the bracket 330. The other end of the slider 412 contains a contact, namely the touch portion 500, which can trigger the roller brush 320 to lower into position detection switch (second detection switch 700) and the roller brush 320 to rise into position detection switch (first detection switch 600).

[0145] When the cleaning device needs to lift the roller brush assembly 300, the motor 421 drives the rod to rotate, causing the slider 412 to move to the right. The second inclined surface 411 on the upper side of the slider 412 pushes up the first inclined surface 310, thereby lifting the roller brush assembly 300 as a whole. When the touch portion 500 on the slider 412 triggers the first detection switch 600, the motor 421 stops rotating. Conversely, when the cleaning device needs to lower the roller brush assembly 300, the motor 421 drives the screw 422 to rotate, causing the slider 412 to move to the left. The second inclined surface 411 on the upper side of the slider 412 is separated from the first inclined surface 310, so that the roller brush assembly 300 as a whole descends under the action of gravity. When the touch portion 500 on the slider 412 triggers the second detection switch 700, the motor 421 stops rotating.

[0146] The drive assembly 400 in this embodiment requires minimal space, effectively utilizing the narrow, unoccupied area below the dust box 200 to drive the roller brush assembly 300 upward and downward, freeing up space in front of the roller brush assembly 300. This drive method is reliable, utilizing the screw rod 422 and the tilting mechanism to prevent stress on the motor 421 during lifting, effectively extending the life of the motor 421. During lowering, the roller brush assembly 300 can be restored to a freely floating state.

[0147] In other embodiments, a gear and rack structure may be used instead of the lead screw drive structure.

[0148] In some embodiments, optionally, the cleaning equipment includes any one of the following: a sweeper, a scrubber, or a sweeper-mop machine.
