[0045] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0046] Embodiments of this disclosure provide a cleaning system, such as Figures 1-3 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be, for example, a mopping robot, a sweeping robot, or a combined sweeping and mopping robot; the cleaning device 10 may include a device body 30, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 20 is used to dock with the cleaning device 10, allowing it to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, water replenishment, and dust collection on the base station 20.

[0047] In some embodiments, the device body 30 is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0048] In some embodiments, the drive module may include a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body 30. In some embodiments, to enable the cleaning device 10 to move more stably or with greater mobility on the ground, the cleaning device 10 may include one or more steering wheels. The steering wheels may be driven wheels or drive wheels, and their structural forms include, but are not limited to, casters. The steering wheels may be located in front of the drive wheel assembly, and a drive motor provides power to the drive wheel assembly and / or the steering wheels.

[0049] In some embodiments, the cleaning device 10 may be a self-propelled cleaning device. The sensing module may include a position determination device located above the device body 30, a buffer located on the forward portion of the device body 30, and a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, and other sensing devices located at the bottom of the device body 30, providing the control module with various position and motion state information of the device body 30. For example, the forward portion of the device body 30 is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure makes the cleaning device 10 respond to the objects, such as stepping over steps.

[0050] In some embodiments, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0051] In some embodiments, the energy module may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device.

[0052] In some embodiments, the human-machine interface module may include buttons on the main control panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available function options to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, and can provide users with richer and more user-friendly functions.

[0053] In some embodiments, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc., while the wet cleaning module may include cleaning components, a water tank, etc. Figure 3 As shown, the cleaning component in the wet cleaning module can be a mopping component 50, such as a roller mop or a tracked mop, to mop the surface to be cleaned.

[0054] The roller mop can be mounted on the equipment body 30 via a mounting bracket, and can clean the area to be cleaned along the travel path of the equipment body 30 under the drive of the equipment body 30. During cleaning, the roller mop is driven by a drive motor to rotate relative to the mounting bracket, and in the process of rotation, it rolls and rubs the surface to be cleaned, thereby efficiently removing dirt. To improve the cleaning efficiency of the roller mop during the rolling and rubbing process, cleaning fluid can be sprayed onto the roller mop, so that the roller mop is wetted by the cleaning fluid before rolling and rubbing the surface to be cleaned, thereby further improving the cleaning efficiency. Similarly, the tracked mop can also be mounted on the equipment body via a mounting bracket, and can be wetted by spraying cleaning fluid before rolling and rubbing the surface to be cleaned.

[0055] like Figures 2-5As shown, when the cleaning equipment 10 includes a wet cleaning module, the equipment body 30 is typically equipped with a removable wastewater box assembly 40 to collect wastewater generated during the cleaning operation of the wet cleaning module. Specifically, the mopping component 50 is sprayed with cleaning fluid to mop the surface to be cleaned, leaving wastewater on the mopping component 50 after mopping. Before the next mopping of the surface to be cleaned, this wastewater needs to be scraped off, and the surface can be re-sprayed with cleaning fluid to improve the mopping effect.

[0056] like Figures 3-6 As shown, the wastewater box 41 includes a box body 411 and a cover plate 412. The cover plate 412 covers the box body 411 to form a liquid storage cavity. The box body 411 includes a bottom plate 4111 and a side plate 4112. The sewage outlet 414 of the wastewater box 41 can be located on the bottom plate 4111 and the side plate 4112 of the wastewater box 41, and drains water by gravity. The wastewater box assembly 40 is also provided with a drainage assembly 42, which can be used to block and open the sewage outlet 414. The drainage assembly 42 includes a blocking component, which has a blocking state and an open state. In the blocking state, the blocking component blocks the sewage outlet 414; in the open state, the blocking component opens the sewage outlet 414.

[0057] The drainage assembly 42 may further include a rotating component, an elastic component, and a sealing component. The rotating component is rotatably mounted on the sewage box assembly 40, and the sealing component is located on the rotating component. Under the elastic force of the elastic component, the rotating component can drive the sealing component to seal the sewage outlet 414. Under the action of external force, the rotating component can overcome the elastic force of the elastic component and rotate relative to the sewage box 41, thereby driving the sealing component to open the sewage outlet 414. In other words, the drainage assembly 42 can keep the sealing component under the pile body that seals the sewage outlet 414 through the elastic component, and the sewage outlet 414 can be opened by pushing the rotating component to rotate through external force, so as to discharge sewage.

[0058] When the cleaning device 10 needs to discharge wastewater, it can automatically locate the base station 20. After docking with the base station 20, the rotating parts on the cleaning device 10 can be pushed by the corresponding trigger components on the base station 20 to open the drain port 414 for wastewater discharge. The wastewater discharged from the wastewater box 41 can be recycled by the base station 20, thus achieving automatic wastewater discharge. Furthermore, after docking with the base station 20, when the cleaning device 10 needs charging, the charging terminal on the cleaning device 10 contacts the charging terminal on the base station 20, enabling the base station 20 to charge the self-propelled cleaning device 10. Further, as... Figures 7-9As shown, the wastewater box assembly 40 integrates a water replenishment component. The side plate 4112 has a water inlet 416 and a water outlet 417. A liquid guide pipe connecting the water inlet 416 and the water outlet 417 is located in the liquid storage chamber. When the cleaning device 10 needs to be replenished with clean water and / or cleaning fluid, it can automatically replenish water by connecting the water inlet 416 on the cleaning device 10 to the water supply nozzle on the base station 20. Therefore, after the cleaning device 10 is connected to the base station 20, it can achieve automatic water replenishment and charging functions without manual operation by the user, thus improving the user experience.

[0059] The triggering component may include a driver and a trigger element. The driver responds to a drain signal to drive the trigger element to move, which in turn drives a rotating element to rotate. This rotating element then drives the sealing element to switch from a sealed state to an open state, opening the drain port 414 for draining. After draining, the driver retracts the trigger element, and the rotating element returns to its initial position under the action of the elastic element, thereby causing the sealing element to re-seal the drain port 414. Since the driver responds to a drain signal to drive the trigger element, the rotating element is only driven to rotate via the triggering component when draining is required. After draining, the triggering component releases the external force applied to the rotating element, thereby releasing the external force indirectly applied to the elastic element. This ensures that the elastic force provided by the elastic element remains within an effective range, thus guaranteeing the sealing performance of the sealing element on the drain port 414 and preventing leakage due to decreased sealing performance. It should be noted that the drainage signal can be sent by the base station 20 or by the cleaning equipment 10. For example, when the cleaning equipment 10 determines that the liquid level in the sewage box 41 has reached a preset height, after the cleaning equipment 10 is connected to the base station 20, the driver can send a drainage signal to the trigger component to control the opening of the drainage component 42 to open the sewage outlet 414 for sewage discharge.

[0060] The driver can be a drive motor, and a gear can be installed on the output shaft of the drive motor. The trigger element can be fixed on a rack, and the gear meshes with the rack. The drive motor drives the gear to rotate, which in turn drives the rack to reciprocate along the length of the rack, thereby driving the trigger element to reciprocate, thus pushing the rotating element. In some embodiments, the trigger component may include a protrusion structure formed on the base station 20. When the cleaning device 10 docks with the base station 20, the protrusion structure can directly push the rotating element to rotate, so that the sealing element is in the open state; when the cleaning device 10 separates from the base station 20, the sealing element returns to the sealed state.

[0061] In some embodiments, the drain assembly 42 may be an electric valve assembly, and the sealing element may be in a sealed or open state under electric drive, that is, the cleaning equipment 10 may open the drain assembly 42 to open or seal the drain outlet 414 on its own without the need to cooperate with the base station 20.

[0062] In some embodiments, such as Figures 4-6 As shown, the wastewater box assembly 40 also includes: a side cover plate 43, which is connected to the wastewater box 41, and a drain assembly 42 located between the side cover plate 43 and the wastewater box 41; the side cover plate 43 has an operating hole 431, through which the first end of the rotating component protrudes. The space formed by the side cover plate 43 and the wastewater box 41 provides effective protection for the drain assembly 42. The drain assembly 42 is located inside the side cover plate 43, preventing direct collision with external objects and reducing damage to components caused by collisions; at the same time, the side cover plate 43 also prevents dust, impurities, etc., from entering the interior of the drain assembly 42, ensuring the cleanliness and normal operation of rotating components, elastic components, etc., and extending the service life of the drain assembly 42. The side cover plate 43 conceals the drain assembly 42 between itself and the wastewater box 41, exposing only the operating end of the rotating component, making the wastewater box assembly 40 more aesthetically pleasing. This avoids the exposed components of the drain assembly 42 affecting the overall aesthetics, improves the visual quality of the product, and provides users with a better visual experience. The side cover plate 43 is detachably connected to the sewage box 41, and the rotating part is rotatably connected to the side cover plate 43 and the sewage box 41, that is, the rotating shaft of the rotating part can be rotatably set on the side cover plate 43 and the sewage box 41 respectively.

[0063] However, when the mopping component 50 of the cleaning device 10 is self-cleaning in the cleaning tank of the base station 20, water will be splashed onto the bottom surface of the device body 30, such as the bottom of the wastewater box 41, as the mopping component 50 rotates during the cleaning process. In addition, after the mopping component 50 is washed at high temperature in the base station 20, the high-temperature steam during the high-temperature washing process will condense onto the bottom surface of the device body 30. When there is water on the bottom surface of the device body 30, the cleaning device 10 will drip water from the bottom surface of the device body 30 onto the driving surface after it leaves the base station 20, which will affect the cleaning efficiency, thereby affecting the user experience and thus affecting the market competitiveness of the product.

[0064] To address the aforementioned technical problems, the present disclosure provides a cleaning device 10, which includes a device body 30, a cleaning component, and a water-absorbing component 45. The device body 30 has a receiving portion 31 with a bottom opening. The cleaning component is disposed in the receiving portion 31 and is rotatably connected to the device body 30. The water-absorbing component 45 is disposed on the bottom surface of the device body 30 and at least partially surrounds the opening of the receiving portion 31.

[0065] The cleaning device 10 disclosed herein has a water-absorbing component 45 on the bottom surface of the device body 30. The water-absorbing component 45 is located on at least a portion of the bottom surface of the device body 30 surrounding the opening of the receiving portion 31. The water-absorbing component 45 can absorb water splashed onto the bottom of the device body 30, flowed onto the bottom of the device body 30, and condensed on the bottom of the device body 30, thereby preventing water from accumulating on the bottom of the device body 30 and forming a dripping state. As a result, during the movement of the cleaning device 10, water droplets from the bottom of the device body 30 can be prevented from falling onto the driving surface, thus improving the user experience. At the same time, since there is usually a gap between the bottom of the device body 30 and the driving surface, the water-absorbing component 45 can be designed to fit the size of this gap, achieving full utilization of space without requiring modifications or excessive modifications to the existing device body 30, thereby reducing product manufacturing costs.

[0066] In the forward and backward movement of the cleaning device 10, the water-absorbing component 45 is located behind the opening of the receiving portion 31. During the movement of the cleaning device 10, if water droplets fall onto the driving surface from the front of the opening of the receiving portion 31, the cleaning component will remove the water droplets. However, if water droplets fall onto the driving surface from the rear of the opening of the receiving portion 31, they cannot be removed in time. Therefore, by placing the water-absorbing component 45 behind the opening of the receiving portion 31, water splashed, flowing, or condensed on the bottom surface of the device body 30 can be absorbed in a timely manner, preventing water accumulation and dripping. This prevents water droplets from the bottom surface of the device body 30 from falling onto the driving surface during the movement of the cleaning device 10.

[0067] In some embodiments, such as Figure 3 As shown, the device body 30 includes a wastewater box assembly 40, which is located behind the opening of the receiving portion 31; as Figures 7-10 As shown, a water-absorbing element 45 is provided on the bottom surface of the wastewater box assembly 40, and the water-absorbing element 45 covers at least a portion of the bottom surface of the wastewater box assembly 40.

[0068] By providing a water-absorbing component 45 on the bottom surface of the wastewater box assembly 40, the water-absorbing component 45 can absorb water splashed onto, flowing onto, and condensed on the bottom surface of the wastewater box assembly 40, thereby preventing water accumulation and dripping. This also prevents water droplets from falling onto the driving surface during the movement of the cleaning device 10, improving the user experience. Furthermore, since there is usually a gap between the bottom surface of the wastewater box assembly 40 and the driving surface, the water-absorbing component 45 can be designed to fit this gap, maximizing space utilization without requiring modifications to the existing wastewater box assembly 40, thus reducing manufacturing costs. In addition, placing the water-absorbing component 45 on the bottom surface of the wastewater box assembly 40 does not occupy the liquid storage chamber space of the wastewater box assembly 40, ensuring the suction capacity of the cleaning device 10 during a single cleaning cycle.

[0069] It should be noted that since the sewage box assembly 40 is detachably connected to the equipment body 30, when the water suction component 45 is only provided on the bottom surface of the sewage box assembly 40, the water suction component 45 can be regarded as part of the sewage box assembly 40.

[0070] The water-absorbing component 45 is located on the bottom surface of the sewage box assembly 40 near the cleaning component. Therefore, the water-absorbing component 45 can absorb water that splashes onto the bottom surface of the sewage box assembly 40, flows onto the bottom surface of the sewage box assembly 40, and condenses onto the bottom surface of the sewage box assembly 40 in a timely manner, thereby preventing water from accumulating on the bottom surface of the sewage box assembly 40 and forming a dripping state. As a result, during the movement of the cleaning equipment 10, water droplets on the bottom surface of the sewage box assembly 40 can be prevented from falling onto the driving surface.

[0071] In some embodiments, such as Figure 10 As shown, the wastewater box assembly 40 includes a wastewater box 41 and a water collection component 44. The wastewater box 41 has a liquid storage chamber and a liquid inlet 413. The water collection component 44 has a water collection trough 441, and the liquid inlet 413 of the wastewater box 41 is located in the water collection trough 441. The wastewater box 41 has a negative pressure hole 415 communicating with the liquid storage chamber. The negative pressure hole 415 is used to connect a negative pressure device. When there is wastewater in the water collection trough 441, a negative pressure can be formed in the wastewater box 41 through the negative pressure hole 415 of the wastewater box 41, thereby using the negative pressure to draw the wastewater at the liquid inlet 413 into the wastewater box 41, realizing the recovery of wastewater scraped off by the wiping and mopping component 50 by the squeegee. In some other embodiments, the wastewater on the wiping and mopping component 50 can be directly drawn from the squeegee into the wastewater tank, that is, the water collection component 44 may not be provided in the wastewater box assembly 40.

[0072] However, when the wastewater scraped off the mopping component 50 is collected by the water collection component 44, and the cleaning equipment 10 is driving on uneven driving surfaces or performing operations such as crossing thresholds or climbing steps, the wastewater in the water collection tank 441 may overflow due to shaking. The wastewater flows out along the outer wall of the water collection component 44 to the bottom of the water collection component 44, accumulating and forming a dripping state. During the driving process, the cleaning equipment 10 will drip the accumulated water onto the driving surface, affecting the cleaning efficiency and thus affecting the user experience.

[0073] In response, a water suction component 45 is provided at the bottom of the water collection component 44. When the sewage in the water collection tank 441 flows out along the outer wall of the water collection component 44 to the bottom of the water collection component 44, the water suction component 45 at the bottom of the water collection component 44 can absorb the sewage and prevent it from falling onto the driving surface.

[0074] In some embodiments, the wastewater container 41 includes a container body 411 and a cover plate 412, the container body 411 forming a liquid storage cavity, and the cover plate 412 covering the container body 411. Figure 10 As shown, the water collecting component 44 is connected to the side of the box body 411 near the wiping and mopping component 50 and close to the bottom of the box body 411. The water absorbing component 45 is located at the bottom of the water collecting component 44, that is, the water absorbing component 45 is located close to the wiping and mopping component 50. Therefore, the water absorbing component 45 can absorb water splashed onto the bottom surface of the water collecting component 44, flow onto the bottom surface of the water collecting component 44, and condense onto the bottom surface of the water collecting component 44 in a timely manner, thereby preventing water from accumulating on the bottom surface of the water collecting component 44 and forming a dripping state. Thus, during the movement of the cleaning device 10, water droplets on the bottom surface of the water collecting component 44 can be prevented from falling onto the driving surface. At the same time, the water absorbing component 45 can absorb sewage overflowing from the water collection tank 441 in a timely manner, thereby preventing sewage from accumulating on the bottom surface of the water collecting component 44 and forming a dripping state. Thus, during the movement of the cleaning device 10, sewage droplets can be prevented from falling onto the driving surface.

[0075] The equipment body 30 is provided with a mounting part with a bottom opening, the opening of which is connected to the opening of the receiving part 31, and the sewage box assembly 40 is located in the mounting part.

[0076] At least a portion of the water collecting component 44 is located in the opening of the receiving portion 31, and the water absorbing component 45 is disposed on the bottom surface of the water collecting component 44, that is, the water absorbing component 45 is disposed closer to the mopping component 50. Therefore, the water absorbing component 45 can absorb the water splashed onto the bottom surface of the water collecting component 44 in a timely manner, thereby preventing the water on the bottom surface of the water collecting component 44 from accumulating and forming a dripping state. In this way, during the movement of the cleaning device 10, the water droplets on the bottom surface of the water collecting component 44 can be prevented from falling onto the driving surface.

[0077] Among them, such as Figure 10As shown, the water collecting component 44 and the box body 411 can be an integral structure. This integral structure avoids connection gaps between the water collecting component 44 and the box body 411, effectively preventing sewage leakage from the connection point, reducing equipment contamination and functional malfunctions caused by leakage, and improving the reliability of the sewage box assembly 40. Simultaneously, the integral structure makes the water collecting component 44 and the box body 411 a robust whole, eliminating the risk of loose connections, allowing it to withstand greater external forces and vibrations, reducing deformation or damage, extending the component's service life, and lowering the probability of maintenance. Furthermore, the integral structure can be manufactured using a one-time molding process, reducing the number of parts and assembly steps, improving production efficiency, lowering production costs, and making the structure more compact, saving internal installation space, facilitating miniaturization design, and improving the overall layout rationality of the equipment. In other examples, the water collecting component 44 and the box body 411 can also be a separate structure, for example, detachably connected by snap-fit ​​or threaded connections; this disclosure does not limit this.

[0078] Among them, such as Figure 11 As shown, the shape and size of the water-absorbing component 45 match the shape and size of the bottom surface of the water-collecting component 44, so as to cover as much of the bottom surface of the water-collecting component 44 as possible, thereby improving the water absorption capacity of the water-absorbing component 45.

[0079] In some embodiments, such as Figure 12 As shown, in the depth direction of the liquid storage chamber, the height of the bottom surface of the water collecting component 44 away from the box 411 is greater than the height of the side closer to the box 411, meaning the bottom surface of the water collecting component 44 can be inclined. When the cleaning device 10 cleans the wiping and mopping component 50 at the base station 20, the wastewater is thrown towards the box 411 when the wiping and mopping component 50 rotates at high speed. The inclined bottom surface is designed to reduce the impact force of the splashing water through angle buffering, thereby improving the water absorption capacity of the water suction component 45. At the same time, when wastewater overflows from the water collection tank 441, the overflowing wastewater can flow from the high point to the low point on the bottom surface of the water collecting component 44, thus being better absorbed by the water suction component 45.

[0080] The water collecting component 44 has a decreasing height from the side away from the box 411 towards at least a portion of its bottom surface. This means that when wastewater overflows from the water collecting tank 441, the overflowing wastewater can flow continuously from a higher point to a lower point on the bottom surface of the water collecting component 44, thus being better absorbed by the water suction component 45. Furthermore, by setting the bottom surface of the water collecting component 44 as an inclined surface with decreasing height, full contact between the water suction component 45 and the bottom surface of the water collecting component 44 is ensured, maximizing the adsorption area.

[0081] In some embodiments, such as Figure 12As shown, the height of the bottom surface of the box 411 away from the water collecting component 44 is greater than the height of the side closer to the water collecting component 44, meaning the bottom surface of the box can be tilted. If water splashes, flows, and condenses at the bottom of the box 411, the tilted bottom surface can guide the permeated water to flow towards the side closer to the water collecting component 44, where it is promptly absorbed by the water-absorbing component 45 at the bottom of the water collecting component 44.

[0082] In this design, the bottom surface of the box 411 increases in height from the side closest to the water collecting component 44 towards the side furthest from the water collecting component 44. This means that when there is water at the bottom of the box 411, the water can flow continuously from a higher point to a lower point on the bottom surface of the box 411, thus flowing more effectively to the absorbent component 45 for absorption. Simultaneously, by setting the bottom surface of the box 411 as a sloping surface with decreasing height, with the side closest to the absorbent component 45 being lower, water at the ground level of the water collecting component 44 is prevented from flowing towards the bottom surface of the box 411. Instead, water on the bottom surface of the box 411 flows to the absorbent component 45 by gravity, improving the absorption effect of the absorbent component 45.

[0083] In some embodiments, the absorbent component 45 is detachably connected to the bottom surface of the wastewater box assembly 40, for example, detachably connected to the bottom surface of the water collection component 44. When the water absorbed by the absorbent component 45 reaches saturation and requires maintenance, the absorbent component 45 can be removed from the wastewater box assembly 40, rinsed with clean water, dried, and reused to avoid odors caused by the accumulation of dirt inside the absorbent component 45. Furthermore, if the absorbent component 45 is fixedly connected to the wastewater box assembly 40, when the absorbent component 45 loses its adsorption capacity due to adsorption saturation, aging, or contamination, the user needs to replace the entire wastewater box assembly 40, resulting in high maintenance costs. However, replacing the absorbent component 45 eliminates the need to replace the entire wastewater box assembly 40, allowing the wastewater box assembly 40 to be used continuously with multiple absorbent components 45, thus reducing maintenance costs. Furthermore, when it is necessary to optimize the performance of the water-absorbing component 45 (such as improving water absorption efficiency), the detachable connection design does not require modification of the structure of the wastewater box assembly 40. It can directly replace the original ordinary water-absorbing component 45 without adjusting the mold or production process of the wastewater box assembly 40, thus quickly achieving product upgrades.

[0084] In some embodiments, the absorbent component 45 can be bonded to the bottom surface of the wastewater box assembly 40, such as to the bottom surface of the water collection component 44. The adhesive connection eliminates the need for complex connection structures such as clips, slots, and screw holes on the bottom surface of the wastewater box assembly 40; a simple adhesive layer or application of adhesive is sufficient for fixation. Furthermore, the adhesive method allows the absorbent component 45 to fit snugly against the bottom surface of the wastewater box assembly 40, saving installation space due to the absence of additional connection structures.

[0085] In this embodiment, the water-absorbing component 45 can be bonded to the wastewater box assembly 40 using removable double-sided acrylic adhesive. This ensures the water-absorbing component 45's stability during equipment operation and allows for easy removal by hand during replacement, leaving no adhesive residue on the bottom surface of the wastewater box assembly 40 after disassembly. In other embodiments, the water-absorbing component 45 can be bonded to the wastewater box assembly 40 using Velcro, facilitating the removal of the water-absorbing component 45 for maintenance.

[0086] The absorbent component 45 can be made of materials such as felt, sponge, or absorbent resin. Felt, made from natural or synthetic fibers through needle punching and bonding, possesses a porous structure that gives it excellent absorbency, quickly adsorbing liquid water from the bottom surface of the wastewater box assembly 40 and promptly handling the water sprayed off and condensate after cleaning the base station 20. The felt has a high absorbency ratio, and the adsorbed water is locked in the fiber pores, preventing loss due to equipment vibration or tilting. The felt's softness and plasticity allow it to adapt to various shapes of the bottom surface of the wastewater box assembly 40, closely conforming to the curved surface to prevent water accumulation in gaps. Furthermore, the felt's manufacturing process is simple and cost-effective. In addition, the felt has good resistance to detergents, dirt, and other chemicals in wastewater, without dissolving or degrading, and its absorbency decreases slowly over long-term use.

[0087] In some embodiments, the absorbent component 45 includes a mounting plate and an absorbent layer, with the absorbent layer disposed on the mounting plate. The mounting plate is detachably connected to the wastewater box assembly 40, for example, detachably connected to the water collection component 44. The mounting plate is made of a rigid material (e.g., rigid plastic), possessing high structural strength, and can serve as a carrier frame for the absorbent layer, preventing deformation or displacement of the absorbent layer due to its own softness. The connection between the mounting plate and the wastewater box assembly 40 can be firmly fixed through mechanical structures (e.g., snap-fit, screw connection), withstanding greater tensile force, far exceeding the adhesive connection strength of the absorbent layer. When the cleaning equipment 10 crosses obstacles or vibrates, the felt may warp at the edges due to stretching, while the absorbent component 45 with the mounting plate can be tightly fixed to the wastewater box assembly 40 through snap-fit, allowing the absorbent layer to focus on its absorbent function without considering installation strength, thereby optimizing performance. Furthermore, the detachable connection between the mounting plate and the wastewater box assembly 40 allows for positioning protrusions on the mounting plate and positioning grooves on the wastewater box assembly 40, enabling quick installation after replacing the absorbent layer through the positioning structure, avoiding installation deviations.

[0088] It is understood that the above embodiments describe in detail the example of the bottom surface of the water collection component 44 being provided with the water absorption component 45. Similarly, the water absorption component 45 can also be provided in the same manner on the bottom surface of the box body 411 or in other areas of the device body 30 (e.g., the areas of the sewage box 41 on both sides of the wiping and mopping component 50 in the length direction). At the same time, when the sewage box 41 only includes the box body 411 and does not have the water collection component 44, the water absorption component 45 can be directly provided on the bottom surface of the box body 411.

[0089] In some embodiments, the cleaning device 10 can perform self-cleaning and drying functions on the base station 20. That is, after the cleaning device 10 cleans the mop 50 on the base station 20, since the mop 50 may become moldy or breed bacteria when it is in a damp state, it can be dried on the base station 20 so that the mop 50 remains dry after self-cleaning on the base station 20.

[0090] The base station 20 can be equipped with a drying module and a drying channel connected to the hot air outlet of the drying module. Hot air is provided by the drying module and blown onto the wiping and mopping component 50 through the guide of the drying channel. The wiping and mopping component 50 is dried by the continuous supply of hot air.

[0091] During the self-cleaning and drying process of the mopping component 50, splashed sewage or condensed water will be absorbed by the water-absorbing component 45, resulting in the water-absorbing component 45 being in a damp state, or even reaching a water-absorbing saturation state, which will cause it to lose its water-absorbing performance during the subsequent operation of the cleaning device 10.

[0092] To address this, after the cleaning equipment 10 connects to the base station 20, the water-absorbing component 45 is positioned within the drying channel. This ensures that the hot air blown from the drying module reaches the water-absorbing component 45, drying it. Therefore, when the cleaning equipment 10 leaves the base station 20, the water-absorbing component 45 is dry, providing good water absorption during subsequent cleaning processes. It is understood that the water-absorbing component 45 being located within the drying channel can be an open structure. The water-absorbing component 45 can be located on the open portion of the channel, within the channel, or at the channel's outlet, as long as the hot air can achieve a drying effect. This disclosure does not impose any limitations on this.
