DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

In the absence of further limitations, an element defined by the phrase "comprising a" does not exclude the presence of other identical elements in the product or device comprising the element.

[0044] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Figures 1 and 2 are schematic diagrams of the structure of an automatic cleaning device according to an exemplary embodiment. As shown in Figures 1 and 2, the automatic cleaning device can be a vacuum robot, a mopping / brushing robot, a window climbing robot, etc. The automatic cleaning device can include a mobile platform 100, a sensing system 120, a control system, a drive system 140, a cleaning module 1000, an energy system, and a human-computer interaction system 170. Among them:

[0046] The mobile platform 100 can be configured to automatically move in a target direction on an operating surface. The operating surface can be the surface to be cleaned by the automatic cleaning device. In some embodiments, the automatic cleaning device can be a mopping robot, operating on the ground, with the ground being the operating surface; a window cleaning robot, operating on the exterior glass surface of a building, with the glass being the operating surface; or a pipe cleaning robot, operating on the interior surface of a pipe, with the interior surface of the pipe being the operating surface. For illustrative purposes only, the following description of this application uses a mopping robot as an example.

[0047] In some embodiments, the mobile platform 100 can be an autonomous mobile platform or a non-autonomous mobile platform. The autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions based on unexpected environmental inputs; the non-autonomous mobile platform itself cannot adaptively make operational decisions based on unexpected environmental inputs, but can execute established programs or operate according to certain logic. Accordingly, when the mobile platform 100 is an autonomous mobile platform, the target direction can be determined autonomously by the automatic cleaning device; when the mobile platform 100 is a non-autonomous mobile platform, the target direction can be set by the system or manually. When the mobile platform 100 is an autonomous mobile platform, the mobile platform 100 includes a forward part 111 and a backward part 110.

[0048] The perception system 120 includes a position determination device 121 located above the mobile platform 100, a buffer 122 located on the forward portion 111 of the mobile platform 100, a cliff sensor and ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, odometers and other sensing devices located at the bottom of the mobile platform, which provide the control system with various position information and motion status information of the machine.

[0049] In order to more clearly describe the behavior of the automatic cleaning device, the following directions are defined: the automatic cleaning device can move on the ground by various combinations of movements relative to the following three mutually perpendicular axes defined by the mobile platform 100: the lateral axis x, the front-to-back axis y, and the central vertical axis z. The forward drive direction along the front-to-back axis y is marked as "forward", and the rearward drive direction along the front-to-back axis y is marked as "rearward". The lateral axis x essentially extends between the right wheel and the left wheel of the automatic cleaning device along the axis defined by the center point of the drive wheel assembly. Among them, the automatic cleaning device can rotate around the x-axis. When the forward part of the automatic cleaning device is tilted upward and the rear part is tilted downward, it is "tilting up", and when the forward part of the automatic cleaning device is tilted downward and the rear part is tilted upward, it is "tilting down". In addition, the automatic cleaning device can rotate around the z-axis. In the forward direction of the automatic cleaning device, when the automatic cleaning device is tilted to the right of the y-axis, it is "turning right", and when the automatic cleaning device is tilted to the left of the y-axis, it is "turning left".

[0050] As shown in FIG2 , cliff sensors are provided on the bottom of the mobile platform 100, in front of and behind the drive wheel assembly. These cliff sensors are used to prevent the automatic cleaning device from falling when it moves backward, thereby preventing the automatic cleaning device from being damaged. The aforementioned "front" refers to the side in the same direction as the automatic cleaning device's travel, and the aforementioned "rear" refers to the side opposite to the direction of travel of the automatic cleaning device.

[0051] The location determination device 121 includes but is not limited to a camera and a laser ranging device (LDS).

[0052] The various components of the perception system 120 can operate independently or in conjunction to more accurately achieve their intended functions. Cliff sensors and ultrasonic sensors are used to identify the surface to be cleaned to determine its physical characteristics, including surface material and cleanliness level. Cameras and laser rangefinders can also be used to provide even more accurate judgments.

[0053] The forward portion 111 of the mobile platform 100 is provided with a buffer 122. During the cleaning process, when the drive wheel assembly propels the automated cleaning device across the ground, the buffer 122 detects one or more events (or objects) in the automated cleaning device's path via a sensor system, such as an infrared sensor. The automated cleaning device can control the drive wheel assembly based on the events (or objects) detected by the buffer 122, such as obstacles or walls, so that the automated cleaning device responds to the events (or objects), such as by moving away from the obstacles.

[0054] The control system is arranged on a circuit board in the mobile platform 100, and includes a computing processor, such as a central processing unit, and an application processor, that communicates with a non-temporary memory (such as a hard disk, a flash memory, and a random access memory). The application processor is configured to receive the environmental information sensed by the multiple sensors transmitted by the perception system 120, and to use a positioning algorithm, such as SLAM, based on the obstacle information fed back by the laser ranging device, to draw a real-time map of the environment in which the automatic cleaning equipment is located, and to autonomously determine the driving path based on the environmental information and the environmental map, and then control the drive system 140 to perform operations such as forward, backward, and / or steering based on the autonomously determined driving path. Furthermore, the control system can also decide whether to start the cleaning module 1000 for cleaning operations based on the environmental information and the environmental map.

[0055] Specifically, the control system can combine distance and speed information fed back by sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the robot's current operating state, such as crossing a threshold, getting on a carpet, being on a cliff, being stuck above or below, having a full dust box, being picked up, etc. It also provides specific next-step action strategies for different situations, making the automatic cleaning device more in line with the owner's requirements and providing a better user experience. Furthermore, the control system can plan the most efficient and reasonable cleaning path and method based on the real-time map information drawn by SLAM, greatly improving the cleaning efficiency of the automatic cleaning device.

[0056] The drive system 140 can execute drive commands based on specific distance and angle information, such as x, y and θ components, to manipulate the automatic cleaning device to travel on the ground. The drive system 140 includes a drive wheel assembly 141. The drive system 140 can control the left and right wheels at the same time. In some embodiments, in order to more accurately control the movement of the machine, the drive system 140 includes a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are symmetrically arranged along the horizontal axis defined by the mobile platform 100. In order for the automatic cleaning device to be able to move more stably on the ground or have stronger movement capabilities, the automatic cleaning device may include one or more steering assemblies 142. The steering assembly 142 may be a driven wheel or a driving wheel, and its structural form includes but is not limited to a universal wheel. The steering assembly 142 may be located in front of the drive wheel assembly 141.

[0057] The energy system includes rechargeable batteries, such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. The charging control circuit, battery pack charging temperature detection circuit, and battery undervoltage monitoring circuit are connected to the microcontroller control circuit. The host is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device. If dust adheres to the exposed charging electrodes, the accumulated charge during charging can cause the plastic surrounding the electrodes to melt and deform, or even deform the electrodes themselves, preventing normal charging.

[0058] The human-machine interaction system 170 includes buttons on the main unit panel for users to select functions; a display screen and / or indicator lights and / or a speaker to display the current machine status or function options to the user; and a mobile client application. For route-guided cleaning equipment, the mobile client can display a map of the equipment's environment and the machine's location, providing users with a richer and more user-friendly set of functions.

[0059] The cleaning module 1000 may include a dry cleaning module 300 and / or a wet cleaning module 200. As shown in Figure 2, the dry cleaning module 300 includes, among other things, a roller brush 310. The roller brush, which has some contact with the ground, sweeps up debris from the floor and carries it to the front of the dust collection port between the roller brush and the dust box. The dust is then drawn into the dust box by the suction force generated by the fan and passing through the dust box. The dry cleaning module may also include a side brush 320 with a rotating shaft at an angle relative to the ground to move debris into the roller brush area of ​​the cleaning module.

[0060] According to one of the specific embodiments of the present invention, as shown in FIG3 , the wet cleaning module 200 provided by the present invention is configured to clean at least a portion of the operating surface using a wet cleaning method. Specifically, the wet cleaning module 200 includes a driving component 230, which is used to output a driving force having a first working mode and a second working mode; the wet cleaning module 200 also includes a cleaning component 2000, which includes a first cleaning component 210 and a second cleaning component 220. The first cleaning component 210 is configured to reciprocate in the first working mode of the driving component 230 to clean at least a portion of the operating surface, and the second cleaning component 220 is configured to continuously rotate in the first working mode of the driving component 230 to clean the operating surface. Clean at least a portion of the operating surface; the wet cleaning module 200 further includes a lifting assembly 240, which is configured to lift the cleaning assembly to separate from the operating surface in the second operating mode of the driving assembly 230, and to drop the cleaning assembly to contact the operating surface under the action of gravity; the wet cleaning module 200 further includes a water pumping assembly 250, which has multiple water outlets and is configured to supply water to the first cleaning assembly 210 and the second cleaning assembly 220 respectively in the first operating mode of the driving assembly 230. The cleaning module disclosed in the present invention realizes a structural design in which a plurality of driven assemblies (the first cleaning assembly 210, the second cleaning assembly 220, the lifting assembly 240, and the water pumping assembly 250) are driven to work by switching the operating modes through a single driving assembly 230, thereby simplifying the overall structure of the cleaning module and making the overall design of the cleaning equipment more compact.

[0061] In some embodiments, as shown in FIG3 , the wet cleaning module 200 provided by the present disclosure is configured to clean at least a portion of the work surface using a wet cleaning method; wherein the wet cleaning module 200 includes a support platform 290, a first cleaning assembly 210 and a second cleaning assembly 220 disposed on the side of the support platform 290 facing the work surface, and a drive assembly 230, a lifting assembly 240, and a water pump assembly 250 disposed on the side of the support platform 290 facing the moving platform. The first cleaning assembly 210, driven by the drive assembly 230, reciprocates along the surface to be cleaned. The contact surface of the first cleaning assembly 210 and the surface to be cleaned is provided with a cleaning cloth or a cleaning plate. The reciprocating motion generates high-frequency friction with the surface to be cleaned, thereby removing stains on the surface to be cleaned. The second cleaning assembly 220, driven by the drive assembly 230, continuously rotates along the surface to be cleaned. The contact surface of the second cleaning assembly 220 and the surface to be cleaned is also provided with a cleaning cloth or a cleaning plate. The continuous rotation generates high-frequency friction with the surface to be cleaned, thereby removing stains on the surface to be cleaned.

[0062] In some embodiments, the second cleaning assembly is disposed at an edge of the first cleaning assembly, and the second cleaning assembly is configured to continuously rotate under the drive of the drive assembly to clean at least a portion of the work surface. The first cleaning assembly has a plurality of water distribution holes, and the first cleaning assembly is configured to reciprocate under the drive of the drive assembly to clean at least a portion of the work surface.

[0063] It is understandable that the higher the friction frequency, the more friction times per unit time. High-frequency reciprocating motion, also called reciprocating vibration, has a much greater cleaning ability than ordinary reciprocating motion. For example, if the frequency of high-frequency vibration is set to the frequency of sound waves, the tufts on the surface of the first cleaning component 210 will be more uniformly extended in the same direction under the vibration of high-frequency vibration, so the overall cleaning effect is more uniform, rather than just applying downward pressure to the tufts on the surface of the first cleaning component 210 to increase friction and improve the cleaning effect under low-frequency rotation. The downward pressure alone will not make the tufts extend in nearly the same direction. The effect is that the water marks on the operating surface after high-frequency vibration cleaning are more uniform, and no messy water stains will be left.

[0064] Reciprocating motion can be repeated movement along any one or more directions within the operating surface, or it can be vibration perpendicular to the operating surface, without strict restrictions. In some embodiments, the reciprocating motion of the cleaning module is approximately perpendicular to the machine's direction of travel. Reciprocating motion parallel to the machine's direction of travel can cause instability to the moving machine itself, as the thrust and resistance in the direction of travel can easily cause the drive wheels to slip. The impact of slippage is even more significant when a wet cleaning module is included, as the slippery operating surface increases the likelihood of slippage. In addition to affecting the machine's smooth movement and cleaning, slippage can also cause inaccurate ranging measurements by sensors such as the odometer and gyroscope, resulting in inaccurate positioning and mapping of the navigation-based automatic cleaning device. In the event of frequent slippage, the impact on SLAM will be non-negligible, so it is necessary to minimize slippage in machine behavior. In addition to slippage, the cleaning head's motion component in the machine's direction of travel causes the machine to be constantly pushed forward and backward as it moves, resulting in jerky and unstable movement.

[0065] The cleaning intensity and efficiency of the cleaning equipment can also be automatically and dynamically adjusted based on the operating environment of the cleaning equipment. For example, the cleaning equipment can achieve dynamic adjustment based on the physical information of the surface to be cleaned detected by the sensing system 120. For example, the sensing system 120 can detect information such as the flatness of the surface to be cleaned, the material of the surface to be cleaned, and the presence of oil and dust, and transmit this information to the control system of the cleaning equipment. Accordingly, the control system can instruct the cleaning equipment to automatically and dynamically adjust the speed of the motor and the transmission ratio of the power transmission device based on the operating environment of the cleaning equipment, thereby adjusting the preset reciprocating cycle of the reciprocating motion of the first cleaning component.

[0066] For example, when the cleaning device is operating on a flat surface, the preset reciprocating cycle can be automatically and dynamically adjusted to be longer and the water volume of the water pump can be automatically and dynamically adjusted to be smaller; when the automatic cleaning device is operating on an uneven surface, the preset reciprocating cycle can be automatically and dynamically adjusted to be shorter and the water volume of the water pump can be automatically and dynamically adjusted to be larger. This is because a flat surface is easier to clean than an uneven surface, so cleaning an uneven surface requires the first cleaning component to reciprocate faster (i.e., at a higher frequency) and use a larger amount of water.

[0067] For example, when the cleaning device is operating on a tabletop, the preset reciprocating cycle can be automatically and dynamically adjusted to be longer, and the water volume of the water pump can be automatically and dynamically adjusted to be smaller; when the cleaning device is operating on the ground, the preset reciprocating cycle can be automatically and dynamically adjusted to be shorter, and the water volume of the water pump can be automatically and dynamically adjusted to be larger. This is because, compared to the ground, the tabletop has less dust and oil, and the material constituting the tabletop is also easier to clean. Therefore, the first cleaning component needs to perform fewer reciprocating motions, and the water pump needs to provide a relatively small amount of water to clean the tabletop.

[0068] As an optional embodiment of the present invention, a lifting assembly 240 is provided between the support platform 290 and the mobile platform 100, which is used to enable the cleaning assembly to better contact the surface to be cleaned, or to adopt different cleaning strategies for surfaces to be cleaned of different materials. In some embodiments, the dry cleaning module 300 can be connected to the mobile platform 100 through a passive lifting assembly. When the cleaning equipment encounters an obstacle, the dry cleaning module 300 can more conveniently overcome the obstacle through the lifting assembly. In some embodiments, the wet cleaning module 200 can be connected to the mobile platform 100 through an active lifting assembly. When the wet cleaning module 200 is temporarily not involved in the work, or encounters a surface to be cleaned that cannot be cleaned by the wet cleaning module 200, the wet cleaning module 200 is lifted by the active lifting assembly and separated from the surface to be cleaned, thereby achieving a change in the cleaning means.

[0069] In some embodiments, as shown in FIG4-1 , the drive assembly 230 includes a motor 231 . The motor 231 is configured to rotate forward in a first operating mode to output a forward driving force, and to rotate backward in a second operating mode to output a reverse driving force. The motor 231 transmits power to the first cleaning assembly 210 and the second cleaning assembly 220 , the lifting assembly 240 , the water pump assembly 250 , and the like via a power transmission device. The energy system provides power and energy to the motor 231 and is controlled as a whole by a control system. The power transmission device can be a gear or gear set drive, a chain drive, a belt drive, or a worm gear, etc.

[0070] In some embodiments, the drive assembly 230 includes a worm 232, which is connected to the output shaft of the motor 231 and rotates forward or reverse under the drive of the motor 231. The drive assembly 230 also includes multiple drive wheel assemblies 233, which are respectively engaged with the worm 232 and, under the drive of the worm 232 to rotate forward or reverse, respectively drive the first cleaning assembly 210, the second cleaning assembly 220, the water pump assembly 250, and the lifting assembly 240 to operate in the first working mode or the second working mode. It will be understood by those skilled in the art that the drive wheel assembly can be a single gear or a gear set consisting of multiple gears. In which, in response to the forward driving force, the first cleaning component 210 performs reciprocating motion, the second cleaning component 220 performs continuous rotation, and the water pumping component 250 supplies water to the first cleaning component 210 and the second cleaning component 220; in response to the reverse driving force, the first cleaning component 210 stops reciprocating motion, the second cleaning component 220 stops rotating, the water pumping component 250 stops supplying water to the first cleaning component 210 and the second cleaning component 220, and the lifting component 240 lifts the first cleaning component 210 and the second cleaning component 220 to separate them from the operating surface.

[0071] In some embodiments, as shown in Figure 4-1, the drive wheel assembly 233 includes a first drive wheel assembly 2331, and the drive assembly 230 also includes a first power transmission device (not shown) that cooperates with the first drive wheel assembly 2331. The first drive wheel assembly 2331 transmits power to the first cleaning assembly 210 through the first power transmission device, and the first cleaning assembly 210 reciprocates under the drive of the first power transmission device to clean a portion of the operating surface. Since the first cleaning assembly 210 can reciprocate and clean in a local area, it is possible to focus on cleaning local heavily stained areas. In some embodiments, the first drive wheel assembly 2331 is an asymmetric structure, and the first power transmission device can be a vibration connecting rod, which drives the first cleaning assembly 210 to vibrate back and forth under the rotation drive of the asymmetric structure.

[0072] In some embodiments, the drive wheel assembly 233 includes a second drive wheel assembly 2332, and the drive assembly 230 also includes a second power transmission device 23321 that cooperates with the second drive wheel assembly 2332. The second drive wheel assembly 2332 engages with the second power transmission device 23321 to transmit power to the second cleaning assembly 220. Driven by the second power transmission device 23321, the second cleaning assembly 220 continuously rotates to clean a portion of the operating surface. Since the second cleaning assembly 220 can continuously rotate to clean a local area, it is possible to focus on cleaning a local area with heavy stains. In some embodiments, the second power transmission device 23321 can be a gear set with multiple gears meshing, or it can be a synchronous belt drive.

[0073] In some embodiments, as shown in FIG4-2 , the drive wheel assembly 233 includes a third drive wheel assembly 2333, and the drive assembly 230 further includes a third power transmission device 23331 that cooperates with the third drive wheel assembly 2333. Those skilled in the art will appreciate that the third power transmission device 23331 can be a single gear or a gear set consisting of multiple gears. The third drive wheel assembly 2333 engages with the third power transmission device 23331 to transmit power to the water pump assembly 250. Driven by the third power transmission device 23331, the water pump assembly 250 delivers water to the first cleaning assembly 210 and the second cleaning assembly 220.

[0074] In some embodiments, the drive wheel assembly 233 includes a fourth drive wheel assembly, which includes, for example, a clutch assembly 2334. The clutch assembly 2334 is used to directly drive the lifting assembly 240. The lifting assembly 240 includes a cable gear 241 and a cable 242. The clutch assembly 2334 is disposed between the third power transmission device 23331 and the cable gear 241. A cable 242 is wound around the cable gear 241, and the distal end of the cable 242 is wound around the support platform 290. When the motor 231 rotates in the reverse direction, the clutch assembly 2334 engages and connects with the third power transmission device 23331, and the third power transmission device 23331 provides a reverse driving force. Since the clutch assembly 2334 is now counter-engaged with the third power transmission device 23331 and can provide driving force, the third power transmission device 23331 drives the cable gear 241 to rotate via the clutch assembly 2334. As the cable gear 241 rotates, it pulls the support platform 290 via the cable 242. The support platform 290, pulled by the cable 242, lifts the first cleaning assembly 210 and the second cleaning assembly 220. When the motor 231 rotates in the forward direction, the third power transmission device 23331 provides a forward driving force. The clutch assembly 2334 is not engaged with the forward rotation of the third power transmission device 23331 and does not provide driving force. The cable gear 241 cannot pull the support platform 290 via the cable 242.

[0075] As described above, when the motor 231 rotates forward, the drive assembly 230 drives the first cleaning assembly 210 to vibrate and clean through the first drive wheel assembly 2331 and the first power transmission device, drives the second cleaning assembly 220 to rotate and clean through the second drive wheel assembly 2332 and the second power transmission device 23321, and drives the water pump assembly 250 to supply water through the third drive wheel assembly 2333 and the third power transmission device 23331; when the motor 231 rotates backward, the cable gear 241 is driven by the clutch assembly 2334, and the support platform 290 is pulled by the cable 242 to lift the first cleaning assembly 210 and the second cleaning assembly 220. This application realizes the control of four motion modules by one motor. The forward rotation of the motor drives the vibration of the vibrating part and the rotation of the rotating part, while also achieving water supply for easy cleaning. The reverse rotation of the motor drives the lifting assembly to rise and fall. This application allows the drive structure to be reused multiple times, making the entire drive structure more compact, simplifying the number of motors, reducing energy consumption and noise, and improving user experience.

[0076] In the prior art, water pump assemblies either have a single function and a simple structure, failing to meet the cleaning module's requirements for multi-path water flow distribution, or integrate multiple components into a complex water pump assembly. Large water pump assemblies hinder the assembly and layout of other components in the cleaning module, thus affecting the compactness of the cleaning equipment's overall structure.

[0077] Based on this, the present application provides a wet cleaning module, including a cleaning assembly 2000. As described above, the cleaning assembly 2000 may include a first cleaning assembly 210 and a second cleaning assembly 220, or may include only one of the cleaning assemblies, without limitation. The cleaning assembly 2000 includes multiple water distribution holes or water outlets, which provide water to multiple locations of the cleaning assembly to clean at least a portion of the work surface.

[0078] The wet cleaning module also includes a drive assembly 230 configured to output a driving force. The structure of the drive assembly 230 is as described above and will not be elaborated upon here. The wet cleaning module also includes a water pump assembly 250, which supplies water to the cleaning assembly 2000 under the drive of the drive assembly 230. As shown in Figure 5, the water pump assembly 250 includes a housing 253, a water pump component 251, a water pump pipe 254, and a water distributor 252. The water pump component 251, the water pump pipe 254, and the water distributor 252 are disposed within the housing 253. Specifically, one end of the water pumping member 251 is engaged with the third power transmission device 23331 of the drive assembly 230, and the water pumping member 251 rotates under the driving force; the water pumping pipe 254 pumps water under the pressure of the water pumping member 251; at least a portion of the water distributor 252 is engaged with the other end of the water pumping member 251, and the at least a portion of the water distributor 252 rotates with the rotation of the water pumping member 251. The water pumping member 251 rotates while squeezing the water pumping pipe 254, so that the water flow is distributed to the multiple water distribution holes or multiple water outlets through the water distributor 252. Specifically, when the water pumping pipe 254 is squeezed by the rotation of the water pumping component, the water pumping pipe stops pumping water to the water distributor 252; when the water pumping pipe 254 is not squeezed, the water pumping pipe 254 pumps water to the water distributor 252, and the water distributor 252 distributes the water flow to the multiple water distribution holes or the multiple water outlets.

[0079] In some embodiments, the cleaning module includes: multiple water outlets; a water pumping component, including a first end and a second end; a driving assembly, clamped to the first end of the water pumping component to drive the water pumping component to rotate; a water distributor, clamped to the second end of the water pumping component to rotate with the water pumping component when the water pumping component rotates; and a water pumping pipe, arranged on the periphery of the water pumping component, the water pumping pipe supplies water to the water distributor under the rotation and extrusion of the water pumping component, and the water distributor distributes the water flow to the multiple water outlets.

[0080] The water pump assembly 250 disclosed in the present invention integrates the water pump component 251, the water pump pipe 254 and the water divider 252 into a housing 253. The water divider 252 is integrated into the chuck 2513 of the water pump component 251, making it more powerful than a conventional water pump assembly. Conventional water pump assemblies can only output a single water channel, while the water pump assembly of the present application has a water diversion function and can control the output of multiple water channels as needed. Furthermore, the water pump assembly is small in size and does not affect the arrangement of other components within the cleaning module. This allows the cleaning module to have a compact design structure while enhancing its functionality, thereby improving the overall performance of the cleaning device.

[0081] In some embodiments, the water pumping member further comprises a keying slot. The keying slot is located on a side of the water pumping member away from the chuck and engages with the drive assembly. Driven by the drive assembly, the water pumping member rotates, driving the chuck to rotate, thereby squeezing the water pumping pipe to supply water to the water distributor.

[0082] In some embodiments, as shown in Figures 5 and 6, the water pumping member 251 includes a keying groove 25111 connected to the third power transmission device 23331. The keying groove 25111 engages with the third power transmission device 23331 of the drive assembly 230. The water pumping assembly 250 rotates and pumps water under the drive of the third power transmission device 23331, for example, by peristalsis to achieve the water pumping effect. The water pumping assembly can be a gear pump, a vane pump, a plunger pump, a peristaltic pump, etc.

[0083] In some embodiments, as shown in Figures 7 and 8, the water pump assembly 250 includes a water pump component 251 and a water pump pipe 254. The water pump pipe 254 is disposed on the periphery of the water pump component 251. For example, in some embodiments, the water pump pipe 254 wraps around the periphery of the water pump component 251 along its circumference. A keying groove 25111 is disposed approximately at the axis of the water pump component 251, and the water pump component 251 rotates using the driving force of the axis. In some embodiments, the water pump component 251 includes a water pump component body 2511, a turntable 2512, a chuck 2513, and a rotating portion 2514. The turntable 2512 and the chuck 2513 are respectively disposed at opposite ends of the water pump component body 2511. The water pump component body 2511, turntable 2512, and chuck 2513 can be integrally formed to form a generally I-shaped structure. The rotating part 2514 is axially arranged on the outer side wall of the water pumping component body 2511. The rotating part 2514 squeezes the water pumping pipe 254 to pump water. In some embodiments, the rotating part includes a plurality of squeezing parts, which are arranged perpendicular to the surface of the turntable and successively squeeze the water pumping pipe when the water pumping component rotates. For example, the rotating part 2514 is 3-5 squeezing columns that are evenly spaced and arranged along a surface perpendicular to the turntable 2512. As the turntable 2512 rotates, the plurality of squeezing columns successively squeeze the water pumping pipe 254 to achieve peristaltic water discharge. When the water pumping pipe 254 is squeezed, the water path is cut off and water discharge stops. When the water pumping pipe 254 is not squeezed, the water path is unblocked and water discharge begins.

[0084] In some embodiments, the water pumping component also includes: a water pumping component body; a turntable, arranged at one end of the water pumping component body; a chuck, arranged at the other end of the water pumping component body; and a rotating part, arranged on the outer side wall of the water pumping component body along the axial direction of the water pumping component body, and squeezing the water pumping pipe when the water pumping component rotates.

[0085] In some embodiments, the chuck 2513 is disposed on the side of the water pumping member 251 facing the water distributor 252. In some embodiments, the chuck 2513 is a hollow cylindrical structure coaxial with the water pumping member 251, or a claw structure, for example, having 3-5 protruding protruding claws, one end of which is integrally formed with the water pumping member 251. For example, the chuck 2513 has an inner diameter that is larger than the outer diameter of the water pumping member body 2511. The outer sidewall of the chuck is provided with at least one groove. In some embodiments, the outer sidewall of the chuck 2513 is circumferentially provided with multiple reinforcing ribs 25132, which are adjacent to but not in contact with the housing 253. Grooves 25133 are formed between the reinforcing ribs 25132, and at least one sealing ring 255 is provided within the grooves 25133.

[0086] In some embodiments, the cleaning module further includes at least one sealing ring, which corresponds to the at least one groove and is interference-fittedly disposed in the at least one groove.

[0087] In some embodiments, as shown in Figures 7 to 9, the water divider 252 includes a rotor 2521 having at least one rotor water inlet hole 25211. The rotor 2521 is engaged with the chuck 2513 and rotates with the rotation of the chuck 2513. The water divider 252 also includes a static plate 2522, which is disposed on the water outlet side of the rotor 2521 and has multiple static plate water outlet holes 25221. The static plate water outlet holes 25221 are respectively connected to the multiple water outlets of the housing 253. The rotor 2521 rotates continuously relative to the static plate 2522. In response to the overlap of the projection of the at least one rotor water inlet hole 25211 and the static plate water outlet hole 25221, the water divider 252 supplies water to the first cleaning assembly 210 and / or the second cleaning assembly 220 through the static plate water outlet hole 25221 with the overlapping projection. In some embodiments, the moving piece 2521 and the static piece 2522 are selected from at least one of the following materials: ceramic, metal, hard plastic, etc., so as to ensure smooth rotational contact between the moving piece 2521 and the static piece 2522.

[0088] In some embodiments, the water divider includes: a moving plate, which is provided with at least one moving plate hole, and the moving plate can rotate with the rotation of the water pumping component; and a static plate, which is arranged on the water outlet side of the moving plate and is provided with multiple static plate holes, wherein when the moving plate rotates continuously relative to the static plate, the water divider distributes the water flow through the at least one moving plate hole and at least one of the multiple static plate holes that at least partially overlap.

[0089] In some embodiments, the rotor 2521 has one rotor water inlet 25211, and the surface of the static blade 2522 has three to eight static blade water outlets 25221 evenly spaced along the circumference. For example, three static blade water outlets 25221 are provided, each of which is connected to a water outlet pipe. Water is supplied to the first cleaning assembly 210 or the second cleaning assembly 220 through the water outlet pipe. The rotor 2521 is in contact with the static blade 2522, and the rotor 2521 continuously rotates relative to the static blade 2522. As the rotor 2521 continuously rotates relative to the static blade 2522, the rotor water inlet 25211 sequentially slides over the three static blade water outlets 25221. When the projected projection of the moving plate water inlet hole 25211 overlaps with one of the static plate water outlet holes 25221, water flows from the projected moving plate water inlet hole 25211 to the static plate water outlet hole 25221. The water then flows through the static plate water outlet hole 25221 to the first cleaning assembly 210 or the second cleaning assembly 220 connected thereto. It will be understood that the water distributor 252 rotates to supply water to the static plate water outlet holes 25221 in turn, that is, to the water distribution holes or water outlets of the first cleaning assembly 210 or the second cleaning assembly 220 in turn. When the rotating speed of the moving plate 2521 is sufficiently fast, it can be considered that water is continuously supplied to each water distribution hole or water outlet of the first cleaning assembly 210 or the second cleaning assembly 220.

[0090] In some embodiments, at least one chuck protrusion 25131 is provided on the inner sidewall or other location of the chuck 2513. At least one chuck recess 25212 is provided on the edge or other location of the movable plate 2521. The movable plate recess 25212 engages with the chuck protrusion 25131, thereby securing at least a portion of the movable plate 2521 within the chuck 2513. When the chuck 2513 is a claw structure, at least a portion of the movable plate 2521 engages with the claw, securing at least a portion of the movable plate 2521 within the chuck 2513.

[0091] In some embodiments, the chuck includes at least one chuck protrusion, and the movable plate includes at least one movable plate recess, and the movable plate recess cooperates with the chuck protrusion to clamp the movable plate to the chuck.

[0092] In some embodiments, the water pumping component further includes a cavity formed by the clamping connection between the chuck and the movable plate, and the water flows into the cavity through the gap between the chuck and the movable plate, and flows out of the cavity through the at least one movable plate hole and at least one of the multiple static plate holes. In some embodiments, a cavity is formed after the chuck 2513 is clamped with the movable plate 2521. The water flows into the cavity through the gap between the chuck 2513 and the movable plate 2521. As the chuck 2513 and the movable plate 2521 rotate, the water flows out after the movable plate water inlet hole 25211 overlaps with the static plate water outlet hole 25221. This cavity structure can ensure the continuity of water supply to multiple water distribution holes or water outlets, reducing the requirements for the rotation speed of the chuck 2513.

[0093] In some embodiments, as shown in FIG9 , the water pump assembly 250 includes a housing 253 configured to accommodate the rotor 2521, the static fin 2522, the water pumping member 251, and the like. The housing 253 includes multiple water outlets 2531, and the housing has at least one water inlet 2532. Water enters the housing 253 through the water inlet 2532, then flows into the cavity through the gap between the housing 253 and the chuck 2513, passes through the rotor water inlet hole 25211 and the static fin water outlet hole 25221, and then flows out of the at least one water outlet 2531. The water flow direction is shown as the AB direction in FIG9 .

[0094] In some embodiments, the rotor, the static plate, and the water pumping member are disposed in a housing. The housing is provided with a plurality of water outlets and at least one water inlet. The water pumped through the water pump pipe enters the housing through the water inlet, enters the chuck through the gap between the chuck and the rotor, and flows out of the at least one water outlet through the at least one rotor plate hole and at least one of the plurality of static plate holes.

[0095] In some embodiments, as shown in FIG7 , at least one housing protrusion is provided on the inner sidewall of the housing 253. At least one housing recess 25222 is provided on the edge of the static piece 2522. The static piece recess 25222 engages with the housing protrusion, so that the static piece 2522 is engaged in the housing 253.

[0096] In some embodiments, the inner side wall of the shell is provided with at least one shell protrusion, and the edge of the static piece is provided with at least one static piece recess, and the static piece recess cooperates with the shell protrusion to enable the static piece to be clamped in the shell.

[0097] In some embodiments, the water pump assembly 250 further includes a soft rubber pad disposed on the side of the static piece 2522 away from the moving piece 2521. The soft rubber pad includes at least one soft rubber pad hole, which corresponds one-to-one with the static piece water outlet hole 25221. The soft rubber pad seals between the static piece 2522 and the housing 253, preventing water entering the housing 253 through the water inlet from flowing directly toward the static piece 2522.

[0098] In some embodiments, the cleaning module further includes a first soft rubber pad, which is arranged on a side of the static sheet facing away from the dynamic sheet.

[0099] In some embodiments, the water pump assembly 250 also includes a soft rubber pad, which is arranged between the moving plate 2521 and the chuck 2513; and a sealing structure, which is arranged between the static plate 2522 and the outer shell 253 to prevent water entering the outer shell 253 from the water inlet from flowing directly to the side of the static plate 2522.
