[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on the present utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a cleaning base 10 for mounting on a cleaning base station to at least support a cleaning robot 30. Figure 1 This is a diagram illustrating the 30 cleaning robots docked at a cleaning base station. Figure 2This is an exploded view of the cleaning base station. It can be understood that the cleaning base station includes a cleaning base 10, which can be used to transfer and automatically process waste from the dustbin of the cleaning robot 30, and can also rinse the cleaning robot 30 and clean its mop. It should be noted that the cleaning robot 30 includes, but is not limited to, a sweeper-mop robot, a mopping robot, a combined sweeper-mop robot, or a floor scrubber. The application scenarios in this embodiment do not limit the structure of the cleaning base 10 and the cleaning base station in this invention.

[0023] like Figure 3 and Figure 4 As shown, the cleaning base 10 includes a base 1 and a filter cover 2. Wherein, Figure 3 A top view of the cleaning base 10. Figure 4 This is a partial exploded view of the cleaning base 10. The base 1 is the main support structure of the cleaning base 10. The base 1 includes a cleaning tank 11 and a drain hole 12 communicating with the cleaning tank 11. The cleaning tank 11 is a recess for receiving and containing wastewater generated during the cleaning process of the cleaning robot 30. The drain hole 12 serves as the final outlet for the wastewater in the cleaning tank. A filter cover 2 is installed inside the cleaning tank 11. The filter cover 2 includes a first filter section 21, a second filter section 22, and a stepped section 23 connecting the first filter section 21 and the second filter section 22. It should be noted that the first filter section 21, the second filter section 22, and the stepped section 23 are merely divisions of areas on the filter cover 2 according to position and / or function, and do not represent the filter cover 2 as multiple independent components. The first filter section 21 and the second filter section 22 are the parts that actually perform the filtration function. The filtration method of the first filter section 21 and the second filter section 22 can be adsorption filtration by setting filter cotton, or physical filtration by setting a filter structure, such as setting mesh or grid with different pore sizes. The step section 23 is a connection structure with a height difference. The first filter section 21 is connected to the high end of the step section 23, and the second filter section 22 is connected to the low end of the step section 23. That is, the first filter section 21 is at a higher position, and the second filter section 22 is at a lower position.

[0024] like Figure 5 and Figure 6As shown, a first drainage space 211 is formed between the higher-positioned first filter section 21 and the bottom surface of the cleaning tank 11, and the first drainage space 211 is directly connected to the drain hole 12; a second drainage space 221 is formed between the lower-positioned second filter section 22 and the bottom surface of the cleaning tank 11. It can be understood that there is a gap between the lower surface of the first filter section 21 and the bottom surface of the cleaning tank 11, and a gap between the lower surface of the second filter section 22 and the bottom surface of the cleaning tank 11. The second drainage space 221 and the first drainage space 211 are interconnected, so that both the first drainage space 211 and the second drainage space 221 can form a flow path for guiding sewage to the drain hole 12. This dual-layer filtration and drainage structure, with its high and low levels, creates two flow paths for drainage, allowing wastewater to be discharged more promptly and reducing the possibility of wastewater accumulating excessively in the cleaning tank 11 and overflowing. It also creates two filtration paths, enabling graded filtration of impurities and reducing the risk of concentrated blockage in a single filtration area. This allows wastewater to be discharged more smoothly from the cleaning tank 11, further reducing the possibility of wastewater overflowing from the cleaning tank 11.

[0025] The cleaning base 10 provided in this embodiment of the utility model is used to be installed on a cleaning base station to at least support a cleaning robot 30. The cleaning base 10 includes a base 1 and a filter cover 2. The base 1 includes a cleaning tank 11 and a drain hole 12 communicating with the cleaning tank 11. The filter cover 2 is installed in the cleaning tank 11 and includes a first filter part 21, a second filter part 22 spaced apart from the first filter part 21, and a step part 23 connecting the first filter part 21 and the second filter part 22. The first filter part 21 is connected to the high end of the step part 23, and the second filter part 22 is connected to the low end of the step part 23. Both the first filter part 21 and the second filter part 22 are used to filter the wastewater generated by the cleaning robot 30 during the cleaning process. A first drainage space 211, connected to the drainage hole 12, is formed between the first filter section 21 and the bottom surface of the cleaning tank 11. A second drainage space 221, communicating with the first drainage space 211, is formed between the second filter section 22 and the bottom surface of the cleaning tank 11, so that both the first drainage space 211 and the second drainage space 221 can form a flow path for drainage. Thus, by setting up a first filter section 21 and a second filter section 22 with a height difference, and forming the first drainage space 211 and the second drainage space 221 communicating below the first filter section 21 and the second filter section 22 respectively, at least two drainage paths of different height levels are constructed within the cleaning tank 11. When sewage carrying impurities flows in, larger impurities may be intercepted by the higher-positioned first filter section 21, which first contacts the sewage, while smaller impurities may be intercepted by the water flow to the second filter section 22, achieving preliminary graded filtration of impurities. This design reduces the risk of concentrated clogging of a single filtration area. More importantly, even if the flow passage below a certain filter section decreases due to impurity accumulation, another filter section and the drainage space below it can still function as an effective backup drainage path, ensuring that sewage can be smoothly discharged to the drain hole 12 through at least one path. This multi-level, multi-flow-path drainage design significantly improves the overall sewage discharge efficiency and system drainage redundancy during the cleaning process, thereby reducing the possibility of water overflowing from the cleaning tank 11 due to untimely drainage, and improving the operational reliability of the cleaning base 10 and the cleaning station.

[0026] In some embodiments, such as Figure 4 and Figure 5As shown, the stepped portion 23 has a through structure 231. The through structure 231 is a channel that penetrates the side of the stepped portion 23 in the thickness direction. For example, it can be a circular through hole, a strip hole, or an opening of other geometric shapes. A strip hole is preferred to form a grid structure for ease of processing. The through structure 231 connects the first drainage space 211 and the space located above the second filter section 22 for filtering sewage entering the first drainage space 211 from above the second filter section 22. That is, the through structure 231 allows water accumulated above the second filter section 22 to pass through the stepped portion 23 into the first drainage space 211, and the sewage is filtered by the through structure 231 during the flow.

[0027] Thus, by providing a through structure 231 in the step portion 23, a third backup drainage path is added, directly connecting the second filter portion 22 to the first drainage space 211, in addition to the two main drainage paths formed by the first filter portion 21 and the second filter portion 22. When the second filter portion 22 experiences reduced permeability due to impurity accumulation, the water level above the second filter portion 22 gradually rises. When the water level rises to the inlet height of the through structure 231, the accumulated water can flow into the first drainage space 211 through the through structure 231 and finally be discharged from the drain hole 12. This design provides an additional overflow channel for the water in the cleaning tank 11, further reducing the risk of overflow due to complete blockage of the second filter portion 22. The through structure 231 itself can also play an auxiliary filtration role, working in conjunction with the two main filter portions to improve the reliability and drainage efficiency of the entire filtration system and ensure the stable operation of the cleaning base 10.

[0028] In some embodiments, such as Figure 4- Figure 6 As shown, both the first filter section 21 and the second filter section 22 are provided with filter structures. The filter structure is a through-hole or slit penetrating the filter section; for example, it can be a uniformly distributed mesh or a parallel grid, with a mesh structure being preferred to achieve a balanced filtration effect and flow efficiency. The filter structures connect the upper and lower surfaces of the first filter section 21 and the second filter section 22, respectively. For ease of explanation, the filter structure on the first filter section 21 is defined as the first filter structure 212, and the filter structure on the second filter section 22 is defined as the second filter structure 222. Therefore, it can be understood that the first filter structure 212 penetrates the upper and lower surfaces of the first filter section 21, and the second filter structure 222 penetrates the upper and lower surfaces of the second filter section 22. The filter structures are used to filter the sewage entering the first drainage space 211 and the second drainage space 221, respectively, intercepting solid impurities such as hair and fibers carried within. That is, the first filter structure 212 filters the sewage that enters the first drainage space 211 from the upper surface of the first filter section 21, and the second filter structure 222 filters the sewage that enters the second drainage space 221 from the upper surface of the second filter section 22.

[0029] Thus, by directly creating the filter structure on both filter sections, a physical filtration method is achieved without the need for additional filter material. This one-piece molded structure design is simpler than using replaceable filter cotton, reducing the number of parts and assembly steps. The filter structure itself, in the form of mesh or grid, is not easily deformed, maintaining stable filtration performance and reducing the need for frequent maintenance and replacement due to filter material saturation or damage. Furthermore, the hard filter surface formed by the filter section makes it easier for intercepted impurities to be removed by water rinsing or user cleaning, reducing the possibility of clogging the two filter sections. This ensures that the first drainage space 211 and the second drainage space 221 can continuously perform their drainage function, which helps maintain the overall drainage efficiency of the cleaning base 10.

[0030] In some embodiments, such as Figure 4 and Figure 5 As shown, the filter cover 2 also includes a third filter section 24 connected to the first filter section 21. The third filter section 24 extends downward from the first filter section 21 into the first drainage space 211. The third filter section 24 has a third filter structure 241, which can be in the form of a mesh or a grid, etc., for further filtering the sewage flowing into the drain hole 12 in the first drainage space 211.

[0031] Thus, by providing a third filter section 24 within the first drainage space 211, an additional filtration barrier is added before the wastewater is finally discharged. The third filter section 24 can intercept smaller impurities that may pass through the first filter section 21 or enter the first drainage space 211 from other paths (such as the second drainage space 221). If these impurities directly enter the drain hole 12, they may cause blockage of the drain hole 12 or subsequent pipes. The design of the third filter section 24 allows the wastewater in the first drainage space 211 to be more thoroughly purified before discharge, further reducing the possibility of blockage of the drain hole 12 and its downstream flow path, thereby ensuring the long-term unobstructed flow and operational reliability of the entire drainage system. The third filter section 24, together with the first filter section 21 and the second filter section 22, constitutes a multi-level, multi-stage filtration system, improving the filtration effect and drainage stability of the cleaning base 10.

[0032] In some embodiments, such as Figure 5 and Figure 7As shown, the first filter section 21 has a first filter structure 212 on the portion of the third filter section 24 facing away from the drain hole 12. This portion of the first filter section 21 with the first filter structure 212 forms a sludge storage tank 2111 between itself and the bottom surface of the cleaning tank 11, used for temporarily settling sludge mixed with larger particles. The portion of the first filter section 21 in the third filter section 24 facing the drain hole 12 is enclosed. The portion of the first filter section 21 without the first filter structure 212 forms a closed area, forming a water-pumping tank 2112 between itself and the bottom surface of the cleaning tank 11. The water-pumping tank 2112 is directly connected to the drain hole 12. It can be understood that the first filter section 21 is designed with partitioned sections in its relative position to the third filter section 24.

[0033] Thus, by creating a closed area on the first filter section 21 to form a pumping tank 2112, wastewater entering from the top of the cleaning tank 11 cannot directly flow into the pumping tank 2112 near the drain hole 12. Wastewater must first pass through the filtration area of ​​the first filter section 21 (i.e., the area with the first filtration structure 212), undergo preliminary filtration, enter the sludge storage tank 2111, and then undergo further filtration by the third filter section 24 before entering the pumping tank 2112 and finally being discharged from the drain hole 12. This partitioned design establishes a protected, relatively clean pumping area in front of the drain hole 12, reducing the risk of unfiltered wastewater carrying impurities directly approaching and clogging the drain hole 12. Simultaneously, the design of the sludge storage tank 2111 provides a space for sludge sediment to accumulate, confining it to an area away from the drain hole 12 for easy centralized cleaning, thereby further ensuring the long-term unobstructed flow of the drainage system and improving the operational reliability of the cleaning base 10.

[0034] In some embodiments, such as Figure 4- Figure 6As shown, the centerline of the water tank 2112 to be pumped is located on the extension line of the axis of the drain hole 12. This centered layout allows the water in the water tank 2112 to flow directly and smoothly to the drain hole 12. In some embodiments, the height of the second filter section 22 at its own centerline is lower than the height at the edges on both sides of its own centerline, so that the second filter section 22 forms a shallow arched or V-shaped structure that is low in the middle and high on both sides. The centerline of the second filter section 22 is located on the extension line of the centerline of the water tank 2112 to be pumped. This shape helps to guide the water accumulated on the second filter section 22 towards the centerline of the water tank 2112 to be pumped, and finally enter the water tank 2112 to be pumped through the through structure 231 on the step section 23. In some embodiments, the bottom surface of the cleaning tank 11 is lower at its centerline than at its two side edges, creating a recessed structure that is lower in the middle and higher on both sides. The centerline of the cleaning tank 11 is located on the extension of the axis of the drain hole 12. This configuration helps to draw water from the cleaning tank 11 towards the center, allowing it to drain through the drain hole 12. These aforementioned technical features can be implemented individually or in any combination.

[0035] Thus, through the height difference design and the centering of the lowest point, gravity guides the water flow naturally towards the lower central area. This structural design allows wastewater to flow more concentratedly and quickly to the pre-set drain hole 12, reducing water retention and ineffective diffusion within the cleaning tank 11. When these features are used in combination, a continuous flow path can be formed from the second filter section 22 to the bottom surface of the cleaning tank 11, then to the water tank 2112 to be pumped and the drain hole 12, further optimizing the water flow direction. This active flow effect improves the wastewater collection efficiency and discharge speed, reduces the risk of poor drainage due to water dispersion or retention, and thus helps improve the overall drainage performance and operational reliability of the cleaning base 10.

[0036] In some embodiments, such as Figure 4 and Figure 8As shown, the base 1 also includes a water storage tank 13, which is separated from the drain hole 12 and communicates with the first drainage space 211. The water storage tank 13 is an independent water-containing cavity, and the water storage tank 13 is located at least on one side of the drain hole 12. Specifically, the water storage tank 13 can be symmetrically arranged on both sides of the drain hole 12, or it can be arranged only on one side of the drain hole 12. The cleaning base 10 also includes a detection element 3, which is a sensor element for sensing the water level. The detection element 3 is installed in the water storage tank 13. When the water level in the water storage tank 13 reaches a set height, the detection element 3 is triggered to generate a pumping signal. This pumping signal controls the cleaning base station to start a pumping device through the drain hole 12. Specifically, the pumping device can be a water pump. In a specific implementation, the cleaning base 10 may have one water storage tank 13 or multiple water storage tanks 13; in this embodiment, two water storage tanks 13 are provided, and they are located on both sides of the drain hole 12 respectively. Each water storage tank 13 is equipped with a detection element 3. The polarities of the two detection elements 3 are opposite, and they can form a circuit connection when triggered.

[0037] Thus, by setting up the water storage tank 13 and the detection element 3, the drainage process is automatically controlled. When sewage accumulates in the drainage space and the water level in the water storage tank 13 reaches a set height, the detection element 3 is triggered and the pumping program is started. This automatic pumping mechanism can discharge the accumulated water in the cleaning tank 11 in a relatively timely manner, reducing the possibility of water overflowing from the cleaning tank 11 due to untimely drainage. At the same time, the negative pressure suction generated during the pumping process can accelerate the water flow through the filter channel and the drainage channel, reducing the possibility of the filter channel and the drainage channel being blocked, and improving the efficiency of sewage being discharged from the cleaning tank 11 to the drain hole 12.

[0038] In some embodiments, such as Figure 5 and Figure 8 As shown, the filter cover 2 also includes a fourth filter section 25, which is located on the side of the first filter section 21 facing the water storage tank 13. It can be understood that the fourth filter section 25 is located between the first filter section 21 and the water storage tank 13. The fourth filter section 25 has a fourth filter structure 251, which can be a mesh or a grid. Regardless of its specific shape, the fourth filter structure 251 is sufficient as long as it can achieve filtration. The fourth filter structure 251 connects the water storage tank 13 and the first drainage space 211 to filter the wastewater entering the water storage tank 13 from the first drainage space 211. Thus, by providing the fourth filter section 25, the cleanliness of the wastewater entering the fourth filter section 25 is improved, reducing the possibility of larger particles entering the water storage tank 13, thereby reducing the possibility of the water storage tank 13 becoming clogged and causing abnormal start of the pumping process, and improving the working reliability of the detection element 3.

[0039] In some embodiments, such as Figure 4 andFigure 8 As shown, the lowest point of the detection element 3 is located below the first filter section 21, while the fourth filter structure 251 extends upward above the first filter section 21, meaning the highest point of the fourth filter structure 251 exceeds the height of the upper surface of the first filter section 21. This structural layout allows wastewater accumulated on the upper surface of the first filter section 21 to enter the interior of the water storage tank 13 through the fourth filter structure 251 and accumulate within the water storage tank 13. When the accumulation height reaches a set height, the detection element 3 is triggered to operate.

[0040] Thus, by setting the highest point of the fourth filter structure 251 above the first filter section 21 and setting the trigger position of the detection element 3 below the first filter section 21, a water flow path is established directly from the top of the first filter section 21 to the water storage tank 13. When the first filter section 21 is unable to pass through the first drainage space 211 in time due to the accumulation of impurities, the water above the first filter section 21 can flow into the water storage tank 13 through the fourth filter structure 251, causing the water level in the water storage tank 13 to quickly reach the set height and trigger the pumping procedure. This design realizes the monitoring and response to the water level upstream of the first filter section 21, and can start the drainage procedure in time before the water overflows the cleaning tank 11. The active pumping started after the detection element 3 is triggered can not only accelerate the drainage process, but the negative pressure generated can also help drive the water flow near the first filter section 21, which can alleviate the blockage of the first filter structure 212 on the first filter section 21 to a certain extent. This early warning and active intervention mechanism effectively reduces the risk of water overflow due to untimely drainage and improves the safety and reliability of the cleaning base 10.

[0041] In some embodiments, such as Figure 4 As shown, the filter cover 2 also includes two fifth filter sections 26. The first filter section 21 and the second filter section 22 are connected between the two fifth filter sections 26, forming the main support frame of the filter cover 2. The fifth filter sections 26 are used to generate continuous frictional contact with the rotating mop at the bottom of the cleaning robot 30 during cleaning operations, removing sewage and impurities adsorbed on the surface of the mop through physical scraping. Specifically, the fifth filter sections 26 can be made of a wear-resistant and somewhat elastic material, and the surface of the fifth filter sections 26 can be designed as a continuous corrugated structure or intermittent raised stripes.

[0042] Thus, the fifth filter unit 26 achieves active squeegeeing and cleaning of the mop through mechanical interference with the rotating mop. During the squeegeeing process, the fifth filter unit 26 effectively removes saturated dirty liquid from the mop, preventing dirty water from being repeatedly carried away by the cleaning robot 30. Simultaneously, this squeegeeing action removes particulate impurities adhering deep to the mop fibers, achieving a deep cleaning effect. The reduced moisture content of the mop after squeegeeing, combined with the drying airflow that may be equipped at the cleaning base station, allows the mop to dry more quickly, improving its hygiene during cleaning intervals and preparing it for the next cleaning task. This integrated design achieves multiple functions—washing, squeegeeing, and drainage—within a limited space, optimizing cleaning efficiency and enhancing the user experience.

[0043] In some embodiments, such as Figure 4 and Figure 5 As shown, the fifth filtration unit 26 includes a base 261 and a scraper 262. The base 261 is the basic support structure of the fifth filtration unit 26. A drain trough 2611 is provided on the base 261, which communicates with the first drainage space 211 and the second drainage space 221 for discharging the wastewater scraped by the scraper 262. The scraper 262 protrudes above the base 261 and can be a strip-shaped or sheet-shaped structure protruding above the base 261. The scraper 262 can be made of a wear-resistant elastic material, such as silicone or rubber. The scraper 262 is used to abut against the surface of the mop of the cleaning robot 30 during operation, thereby scraping away the wastewater on the surface of the mop during the rotation of the mop. The scraper 262 is located at least on one side of the drain trough 2611. Specifically, the scraper 262 may be provided only on one side of the drain trough 2611, or the scraper 262 may be provided on both sides of the drain trough 2611 at the same time, forming an enclosing structure of the drain trough 2611.

[0044] Thus, the combined functions of the drain trough 2611 and the raised scraper 262 on the base 261 achieve the synergistic effect of scraping water and draining the mop. When the rotating mop of the cleaning robot 30 comes into contact with the scraper 262, the scraper 262 can effectively scrape off the sewage and impurities adsorbed on the surface of the mop through mechanical interference. The scraped liquid and solid impurities then fall into the drain trough 2611 below. The drain trough 2611 not only serves as a drainage channel to guide the sewage scraped by the scraper 262 to the first drainage space 211 and the second drainage space 221, but its trough structure also provides a temporary impurity containment space, preventing the scraped material from immediately entering the first drainage space 211 and the second drainage space 221 and causing blockage of the two drainage spaces. The combined use of the scraper 262 and the drain trough 2611 improves the scraping efficiency and drainage reliability of the cleaning base 10, while reducing the possibility of the drainage performance of the drainage space being affected by the accumulation of scraped material.

[0045] In some embodiments, such as Figure 5 and Figure 7 As shown, the sewage trough 2611 extends vertically through the base 261, forming a channel structure that runs vertically through the body. At the same time, a certain distance is maintained between part of the bottom surface of the base 261 and the bottom surface of the cleaning trough 11, forming a continuous gap space. This gap space is connected to the first drainage space 211 and the second drainage space 221.

[0046] Thus, by designing the drain trough 2611 as a vertically penetrating structure and pre-setting a partial assembly gap between the base 261 and the bottom surface of the cleaning tank 11, the natural assembly relationship between the parts is cleverly utilized to form a drainage channel. This design eliminates the need for additional dedicated through-hole structures on the side wall of the base 261, allowing the side wall of the base 261 to remain intact and reducing the possibility of dirt residue remaining in dead corners. At the same time, the combination of the vertically penetrating drain trough 2611 and the bottom gap allows the wastewater scraped by the scraper 262 to be quickly discharged downwards and smoothly flow into the main drainage system (i.e., the first drainage space 211 and the second drainage space 221). With this configuration, the fifth filter unit 26 can maintain high drainage efficiency with a simple structure, facilitating implementation and maintenance.

[0047] In some embodiments, such as Figure 4 As shown, the filter cover 2 also includes a first connecting structure 27, and the base 1 also includes a second connecting structure 14 adapted to the first connecting structure 27. The first connecting structure 27 and the second connecting structure 14 are detachably connected. The first connecting structure 27 and the second connecting structure 14 can be a snap-fit ​​and a slot, a magnet and a magnetic sheet in a magnetic attraction assembly, or a threaded stud and a threaded hole, etc. Regardless of the specific connection structure of the first connecting structure 27 and the second connecting structure 14, as long as the first connecting structure 27 and the second connecting structure 14 can allow the filter cover 2 and the base 1 to be detachably connected.

[0048] Thus, by providing a detachable first connecting structure 27 and a second connecting structure 14, the filter cover 2 and the base 1 can be easily disassembled and assembled. After the cleaning base 10 has completed its cleaning task, the user can easily remove the filter cover 2 from the cleaning tank 11, thereby thoroughly rinsing and cleaning all surfaces of the filter cover 2, especially the first filter section 21 and the second filter section 22, of any solid impurities such as hair and fibers. This detachable design avoids the inconvenience of cleaning the filter cover 2 within the cleaning tank 11, making the cleaning and maintenance of the filter cover 2 simpler and more thorough. Regularly cleaning the filter cover 2 helps maintain its stable performance, prevents long-term accumulation of impurities from affecting drainage efficiency, and also improves the hygiene of the cleaning base 10 for long-term use.

[0049] like Figure 1 and Figure 2As shown, this embodiment of the present invention also provides a cleaning base station, which includes a body 20 and a cleaning base 10. The body 20 is the main supporting structure of the cleaning base station, and its interior has a docking compartment 201, which is a space for accommodating and positioning a cleaning robot 30. When the cleaning robot 30 is docked in the docking compartment 201, the cleaning base station can perform interactive operations such as charging, cleaning, and sewage discharge on the cleaning robot 30. The bottom of the body 20 also has a bottom opening 202 communicating with the docking compartment 201. The cleaning base 10 is disposed at the bottom opening 202, and the bottom opening 202 of the docking compartment 201 is closed to form the base of the cleaning base station. The cleaning base 10 can be any of the cleaning bases described in the above embodiments.

[0050] Thus, by integrating the cleaning base 10, which features multi-stage filtration and efficient drainage, into the bottom opening 202 of the cleaning base station, a stable cleaning platform is provided for the cleaning robot 30, and wastewater generated during cleaning within the docking compartment 201 can be effectively collected and quickly discharged. The cleaning base 10 performs staged filtration of wastewater, reducing the risk of drainage system blockage; the multi-path drainage design of the cleaning base 10 improves drainage efficiency and reduces the possibility of wastewater overflowing from the cleaning tank 11 to the outside. This modular integration allows the cleaning base station to inherit the technological advantages of the cleaning base 10, resulting in reliable filtration performance, efficient drainage capacity, and convenient maintenance, thereby improving the overall reliability and user experience of the cleaning base station.

[0051] The above description is merely an embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this utility model are included within the scope of protection of this utility model.
