Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] With the continuous development of smart home technology, cleaning devices with self-cleaning functions are becoming increasingly popular. Such devices are usually equipped with a base station for charging the host, replenishing clean water, recycling sewage, and cleaning the roller brush, etc. The base station usually has a cleaning plate inside to support the roller brush and other components of the host.

[0045] At present, the cleaning plate of the base station is not detachable and the cleaning process is cumbersome, which makes it inconvenient to clean the cleaning plate, resulting in low user willingness to clean, easy accumulation of dirt and grime, bacterial growth, odor, and other adverse effects on user health.

[0046] In order to overcome the defects in the prior art, after repeated consideration and verification, the inventors discovered that if a water spray nozzle is set on the cleaning tray, the cleaning tray can be automatically cleaned by high-pressure water rinsing. This achieves efficient removal of dirt without disassembling the cleaning tray, thereby preventing long-term accumulation of dirt, reducing bacterial growth and odor problems, and improving the user experience and satisfaction.

[0047] In view of this, this application provides a base station for use in a cleaning system. The base station includes:

[0048] a clean water tank;

[0049] a water storage tank, equipped with a water inlet, an air inlet, and a water outlet controlled by a valve. The water inlet is used to communicate with the clean water tank to introduce liquid into the water storage tank, the air inlet is used to introduce gas into the water storage tank to form a gas-liquid mixture in the water storage tank, and the water outlet is used to output the gas-liquid mixture;

[0050] The cleaning tray is equipped with a spray nozzle, which is connected to the outlet of the water storage tank through a water outlet pipe. This is used to inject a gas-liquid mixture into the cleaning tray to rinse it.

[0051] By setting a water inlet and an air inlet in the water storage tank, a gas-liquid mixture can be formed in the water storage tank. As per the instruction manual (page 3 / 15, CN 121445263 A), the cleaning tray is automatically rinsed by the water outlet, water outlet pipe, and spray nozzle. By using a gas-liquid mixture containing a large number of air bubbles, the bubbles can break upon impact with the surface of the cleaning tray, generating a stronger local impact force and turbulence effect. This more effectively removes stubborn stains adhering to the gaps and grooves of the cleaning tray, achieving a deeper and more thorough cleaning of the cleaning tray. This prevents the long-term accumulation of dirt from the source, significantly reduces bacterial growth and odor problems, and ensures the hygiene and health of the home environment. Furthermore, by impacting the waste into a designated area and discharging it through a high-pressure gas-liquid mixture, it is ensured that the cleaning tray can be restored to a clean state after each cleaning cycle, preventing cross-contamination of dirt and avoiding secondary pollution to the main unit's roller brush caused by an unclean cleaning tray. Simultaneously, this process is entirely automated by the base station, requiring no manual handling by the user, fundamentally solving the problem of users being unwilling to clean due to the tedious cleaning process, thus improving the user experience and satisfaction.

[0052] The content of this application will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly and thoroughly understand the content of this application.

[0053] The specific structure of the base station and various possible implementation methods are described in detail below.

Figure 10 is another structural diagram of the water tank and cleaning tray of the base station shown in Figure 1.

[0055] As shown in Figure 1, the base station 100 provided in this application embodiment is applied to a cleaning system. The base station 100 is used to provide functions such as charging, clean water replenishment, sewage recycling, and cleaning roller brush for the cleaning equipment in the cleaning system.

[0056] The cleaning equipment is used in home life and can realize automatic cleaning of the house. It is also suitable for cleaning selected areas, saving time and effort and freeing up human hands.

[0057] In one possible implementation, the cleaning equipment can be a sweeping robot. But it is not limited to this, in other possibleIn the implementation, the cleaning equipment can also be a sweeping and mopping machine or other movable cleaning equipment that meets cleaning needs.

[0058] Please also refer to Figure 2. The base station 100 includes a housing 10, a water tank 20, and a cleaning tray 30. The housing 10 is the main body of the base station 100. The water tank 20 and the cleaning tray 30 are respectively disposed on the housing 10. The water tank 20 is used to provide water for cleaning the cleaning tray 30. The cleaning tray 30 is used to support the cleaning equipment.

[0059] Please also refer to Figure 3. The water tank 20 provided in this embodiment of the application is provided with a water inlet 21, an air inlet 22, and a water outlet 23 controlled by a valve. The water inlet 21 is used to communicate with the clean water tank 70 of the cleaning system to introduce liquid into the water tank 20. The air inlet 22 is used to introduce gas into the water storage tank 20 to pressurize the water storage tank 20, thereby mixing the gas and liquid in the water storage tank 20 to form a gas-liquid mixture fluid, which is the cleaning liquid used to clean the cleaning tray 30. The water outlet 23 is used to output the gas-liquid mixture fluid to rinse the area to be cleaned. The valve port is used to control the opening and closing of the corresponding opening on the water storage tank 20, so that the water storage tank 20 can switch between a closed state and an open state.

[0060] In one possible implementation, the liquid in the cleaning liquid can be cleaning fluid, clean water, or a mixture of clean water, such as various commonly used cleaning agents (including scented and unscented types), municipal water, special cleaning water, and other liquids that may be used for cleaning. The gas in the cleaning liquid can be air, inert gas (such as nitrogen, argon), or other gaseous media suitable for the cleaning process. Instruction manual, page 4 / 15, CN 121445263 A

[0061] In one possible implementation, the water inlet 21 is used to introduce clean water into the water storage tank 20. The air inlet 22 is used to introduce air into the water storage tank 20.

[0062] In one possible implementation, the valve port can be a separately set control valve, or it can be an input or output valve port integrated on a fluid drive device (such as a pump).

[0063] The water storage tank 20 encapsulates the complete functions of water intake, air pressurization, gas-liquid mixing, and output in an independent unit, making it a standardized high-pressure gas-liquid flushing power source that can realize gas-liquid mixing and is a portable module, so that the water storage tank 20 can be easily adapted to other equipment that requires efficient flushing functions, such as other models of cleaning base stations 100, greatly expanding the application scenarios of the water storage tank 20.

[0064] Meanwhile, the water storage tank 20, as a container specifically designed to generate a gas-liquid mixture, has a single function, ensuring the continuous production of a uniformly mixed and pressure-stable gas-liquid mixture, thereby providing reliable and efficient performance assurance for the entire cleaning system. Furthermore, the independent design of the water storage tank 20 allows for the establishment of standardized production lines and quality inspection processes, thereby simplifying production and maintenance processes and reducing manufacturing costs.

[0065] The cleaning tray 30 is provided with a water spray nozzle 31. The water spray nozzle 31 is connected to the outlet 23 of the water storage tank 20 through a water outlet pipe 231. The water spray nozzle 31 is used to inject the gas-liquid mixture fluid output from the outlet 23 into the cleaning tray 30, thereby rinsing the cleaning tray 30 with the gas-liquid mixture fluid.

[0066] In one possible implementation, the cleaning tray 30 provided in this application embodiment includes a cleaning tank 32. The cleaning tank 32 is used to clean the cleaning equipment placed therein. The water spray nozzle 31 is provided in the cleaning tank 32 and is used to inject the cleaning liquid, i.e., the gas-liquid mixture fluid, into the cleaning tank 32 to rinse the cleaning tank 32.

[0067] By integrating the cleaning tank 32 and the water spray nozzle 31 into an independent cleaning tray 30, the cleaning tray 30 can clean the cleaning tank 32 through the independently designed water spray nozzle 31, thereby improving the hygiene level of the cleaning tray 30. As a fully functional standardized module, the cleaning tray 30 can be independently manufactured, tested, and supplied, realizing the modularization and standardization of the core cleaning components in the base station 100. This simplifies the assembly process of the base station 100 and improves production efficiency. It also provides a standardized interface and replacement basis for different models and capacities of cleaning trays 30 that may appear later.

[0068] Furthermore, since the cleaning tray 30 is the core area for dirt deposition and the component that most needs cleaning or replacement, designing it as an independent component allows users or maintenance personnel to directly replace the cleaning tray 30 individually when it ages, is damaged, or requires deep cleaning due to long-term use, without disassembling or replacing the entire base station 100. This greatly reduces maintenance costs and difficulty and improves user experience.

[0069] The base station 100 of this application, by setting a water inlet 21 and an air inlet 22 in the water storage tank 20, can form a gas-liquid mixture in the water storage tank 20 and automatically flush the cleaning tray 30 through the water outlet 23, the water outlet pipe 231, and the spray nozzle 31. This process is completely automated by the base station 100, requiring no manual intervention from the user. Thus, even with the cleaning disc non-removable, it fundamentally solves the problem of users being unwilling to clean due to the tedious cleaning process, improving the user experience and sense of well-being.

[0070] A gas-liquid mixture containing a large number of bubbles is used. When impacting the surface of the cleaning disc 30, the bubbles burst, generating a stronger local impact force and turbulence effect. This more effectively removes stubborn stains adhering to the gaps and grooves of the cleaning disc 30, achieving a deeper and more thorough cleaning of the cleaning disc 30. This prevents the long-term accumulation of dirt from the source, significantly reducing bacterial growth and odor problems, and ensuring the hygiene and health of the home environment. Furthermore, by impacting the waste into a designated area and discharging it through a high-pressure gas-liquid mixture, it ensures that the cleaning disc 30 returns to a clean state after each cleaning cycle, preventing cross-contamination of dirt and avoiding secondary damage to the main unit's roller brush caused by an unclean cleaning disc 30.Secondary pollution.

[0071] Please also refer to Figure 4. In one possible implementation, the water storage tank 20 includes a tank body 24 and a cover 25. The tank body instruction manual, page 5 / 15, CN 121445263 A, states that 24 is provided with a water storage cavity 241. The cover 25 is placed on the tank body 24 and seals the water storage cavity 241. The water storage cavity 241 is connected to the water inlet 21, the air inlet 22, and the water outlet 23, respectively.

[0072] The openable cover 25 design allows access to the interior of the water storage tank 20. After long-term use, scale or microbial film may accumulate on the inner wall of the water storage tank 20. By opening the cover 25, users or service personnel can easily perform thorough manual cleaning, descaling, or disinfection of the inside of the water storage chamber 241, greatly improving the maintainability and cleaning convenience of the water storage tank 20, effectively preventing blockage of the outlet 23 or secondary pollution caused by internal contamination, and ensuring the long-term hygiene and operational stability of the system.

[0073] At the same time, decomposing the water storage tank 20 into two main components, the tank body 24 and the cover 25, simplifies the mold design and injection molding process, making the production of the water storage tank 20 more efficient and the yield rate higher. This structure also facilitates the installation of other built-in components inside the tank body 24, such as water level sensors and baffles, which facilitates production assembly. Sealing through the independent cover 25 can also form a uniform, reliable, and repeatedly openable and closable sealing interface, allowing its sealing performance to be restored after maintenance. Furthermore, in case of poor sealing, it can be repaired simply by replacing the low-cost sealing ring or the cover 25, without replacing the entire water storage tank 20 assembly, reducing the later maintenance costs.

[0074] Please also refer to Figure 10. In one possible implementation, the base station 100 further includes a sewage pump 40. The spray nozzle 31 includes a first nozzle 311 and two second nozzles 312. The two second nozzles 312 are respectively disposed on both sides of the cleaning pan 30, and the water outlet directions are opposite to each other, for spraying the gas-liquid mixture fluid relative to each other to the areas on both sides of the cleaning pan 30. The first nozzle 311 is disposed in the middle of the cleaning pan 30, for spraying the gas-liquid mixture fluid to the middle area of ​​the cleaning pan 30. The water inlet of the sewage pump 40 is connected to the middle of the cleaning pan 30, for pumping out the sewage collected in the middle of the cleaning pan 30.

[0075] The arrangement of the first nozzle 311 and the two second nozzles 312 ensures that the garbage is collected in the middle of the cleaning pan 30.

[0076] In one possible implementation, two second nozzles 312 are respectively disposed on both sides of the cleaning tank 32, with the water outlet directions opposite to each other, for spraying cleaning liquid relative to each other into the areas on both sides of the cleaning tank 32 to rinse the sides of the cleaning tank 32, and causing the rinsed wastewater to flow to the center of the cleaning tank 32. The first nozzle 311 is disposed in the center of the cleaning tank 32, for spraying cleaning liquid into the center area of ​​the cleaning tank 32 to rinse the center of the cleaning tank 32, and cooperates with the wastewater pump 40 to extract the rinsed wastewater.

[0077] Through the second nozzles 312 located on both sides of the cleaning pan 30 with opposite water outlet directions, the gas-liquid mixture is sprayed from both sides in opposite directions, forming a clean water flow covering the sidewalls and edge areas of the cleaning pan 30. This effectively washes away the dirt attached to the sidewalls and uses the kinetic energy of the fluid counter-current to drive the dirt from both sides toward the center area of ​​the cleaning pan 30. At the same time, the first nozzle 311 located in the middle is responsible for concentrated rinsing of the center area of ​​the cleaning pan 30, ensuring that every area from the edge to the center can be rinsed, eliminating cleaning dead corners. The first nozzle 311 further agitates and suspends the dirt gathered there. The water inlet of the sewage pump 40 is directly connected to the middle of the cleaning pan 30, so that the sewage and dirt gathered in the middle can be pumped away by the sewage pump 40 in a timely and efficient manner, greatly reducing the residence time of sewage in the cleaning pan 30. This prevents the sewage after rinsing from being deposited again or contaminating the cleaned surface due to failure to be discharged in time, thereby eliminating secondary pollution and ensuring the final cleaning effect.

[0078] In one possible implementation, the first nozzle 311 and the two second nozzles 312 may be rotating nozzles, thereby spraying high-pressure water in a 360° rotating manner to cover the entire area of ​​the cleaning disc 30.

[0079] In one possible implementation, the cleaning disc 30 further includes a first three-way pipe 33 and a second three-way pipe 34. The first end of the first three-way pipe 33 is connected to the outlet 23 for connecting the cleaning liquid flowing out of the water storage tank 20, i.e., the gas-liquid mixture. The second end of the first three-way pipe 33 is connected to the first end of the second three-way pipe 34. The third end of the first three-way pipe 33 is connected to the first nozzle 311. The second end of the second three-way pipe 34 is connected to one of the second nozzles 312. The third end of the second three-way pipe 34 is connected to the other second nozzle 312.

[0080] By using two standardized tee fittings, a simple tree-like structure can be used to achieve the diversion from one inlet 21 to three nozzles. Compared to laying a separate inlet pipe 211 for each nozzle, this simplifies the structure and assembly complexity of the pipeline system, and achieves efficient and simplified distribution of single-path water inlet to multiple spray paths.

[0081] At the same time, the first tee pipe 33 performs primary diversion to supply the first nozzle 311 and the entire second branch, and the second tee pipe 34 performs secondary diversion to supply the two second nozzles 312. For the two second nozzles 312 after the second tee pipe 34, it can be ensured that the water flow rate and pressure they receive are similar, thereby ensuring good consistency of the spraying effect at different positions on the cleaning plate 30, avoiding the problem of uneven rinsing force caused by different water path lengths and bends. At the same time, the sewage from the cleaning on both sides is collected in the central area.

[0082] In one possible implementation, the valve of the control outlet 23 is located on the water storage tank 20, or on the firstThe outlet pipe 231 between the three-way pipe 33 and the outlet 23, or located at the first end of the first three-way pipe 33.

[0083] In one possible implementation, the cleaning disc 30 also includes a valve. The valve is located between the third end of the first three-way pipe 33 and the first nozzle 311.

[0084] The orderly rinsing of the cleaning disc 30 can be achieved through valve control. In the first stage, the valve is closed, and the pressurized cleaning liquid first passes through the second three-way pipe 34, simultaneously driving the two second nozzles 312 to powerfully rinse the two sides of the cleaning disc 30. The purpose of this stage is to rinse away the dirt and garbage scattered on both sides and gather them towards the center. In the second stage, after the two sides are rinsed, the valve is opened, the first nozzle 311 starts working, rinses the central area, and removes the sewage that has gathered in the central area through the sewage pump 40. The valve can be opened by timed opening or by pressure sensing. This time-sequential rinsing avoids the possibility of scattering garbage from the center to the corners in the initial rinsing stage. Through orderly fluid guidance, it ensures that the garbage is effectively concentrated and ultimately removed.

[0085] At the same time, in the initial stage, closing the branch of the first nozzle 311 can concentrate all the water flow and pressure to supply the two second nozzles 312, so that they can obtain the maximum rinsing kinetic energy and ensure sufficient cleaning power for the two sides. When the valve is opened and the first nozzle 311 starts to work, the system pressure will be redistributed. Since the garbage on both sides has been flushed out and driven to the middle, the second nozzle 312 does not need extremely high pressure to complete the rinsing, while the first nozzle 311 has greater kinetic energy to clean the middle area. This realizes the on-demand distribution of the gas-liquid mixed fluid pressure in the water tank 20 and ensures the rinsing intensity at each stage.

[0086] In one possible implementation, the cleaning plate 30 also includes a four-way pipe. The first end of the four-way pipe is connected to the outlet 23 to connect the cleaning liquid flowing out of the water tank 20, that is, the gas-liquid mixed fluid. The second end of the four-way pipe is connected to the first nozzle 311. The third end of the four-way pipe is connected to one of the second nozzles 312. The fourth end of the four-way pipe is connected to the other second nozzle 312.

[0087] Replacing the combination of the first three-way pipe 33 and the second three-way pipe 34 with a four-way pipe reduces the core components of the diversion system from two to one, simplifying the complexity of the pipeline and the number of parts, reducing connection points, lowering the potential risk of leakage, and improving assembly efficiency and production consistency. The space occupied by a single four-way pipe is usually less than the space required by two three-way pipes and the connecting pipes between them, freeing up more valuable design space inside the base station 100, facilitating the arrangement of other components or the implementation of a more compact product design.

[0088] At the same time, compared with two three-way pipes connected in series, the flow path inside a single four-way pipe is usually more direct and smoother. Water flowAfter entering from the inlet, it only needs to go through one diversion to reach the three outlets, while the series three-way pipe scheme requires two diversions, reducing the change of water flow direction and impact, thereby reducing the pressure loss of the entire diversion system. Under the same inlet water pressure, it can provide a larger total flow rate for the three nozzles, or consume less pump power to achieve the same flow rate. Specification 7 / 15 pages 10 CN 121445263 A

[0089] In one possible implementation, the cleaning plate 30 also includes a valve. The valve is located between the second end of the four-way pipe and the first nozzle 311.

[0090] Through valve control, the orderly flushing of the cleaning plate 30 can be achieved. In the first stage, the valve is closed, and the pressurized cleaning liquid first drives the two second nozzles 312 to powerfully flush the two sides of the cleaning plate 30. The purpose of this stage is to flush the dirt and garbage scattered on both sides and converge them towards the center. In the second stage, after the two sides are flushed, the valve is opened, the first nozzle 311 starts to work, flushes the central area, and removes the sewage that has been gathered in the central area by the sewage pump 40. The valve can be opened by a timed opening or by pressure sensing. This time-sequential flushing avoids the possibility of scattering garbage from the center to the corners in the initial flushing stage. Through orderly fluid guidance, it ensures that the garbage is effectively concentrated and eventually removed.

[0091] At the same time, in the initial stage, closing the branch of the first nozzle 311 can concentrate all the water flow and pressure to supply the two second nozzles 312, so that they can obtain the maximum flushing kinetic energy and ensure sufficient cleaning power for the two sides. When the valve is opened and the first nozzle 311 starts to work, the system pressure will be redistributed. Since the garbage on both sides has been flushed out and driven to the middle, the second nozzle 312 does not need extremely high pressure to complete the flushing, while the first nozzle 311 has greater kinetic energy to clean the middle area. This realizes the on-demand distribution of the gas-liquid mixed fluid pressure in the water tank 20 and ensures the flushing intensity at each stage.

[0092] In one possible implementation, the valve is a solenoid valve.

[0093] Referring also to Figure 9, in one possible implementation, the cleaning tray 30 is further provided with a sewage outlet 321. The sewage outlet 321 is opposite to the first nozzle 311. The sewage outlet 321 is used to collect sewage in the cleaning tank 32. The sewage outlet 321 is connected to the water inlet of the sewage pump 40.

[0094] By aligning the sewage outlet 321 with the first nozzle 311, the shortest and most direct waste discharge path is achieved. The water flow sprayed from the first nozzle 311 not only cleans the cleaning tank 32 but also serves as the power source for transporting waste, directly flushing the sewage into the opposite sewage outlet 321. This avoids the ineffective circulation or retention of sewage and garbage in the cleaning tank 32, thereby enabling the sewage pump 40 to discharge the sewage and improving the sewage discharge efficiency.

[0095] When the high-pressure water flow is ejected from the first nozzle 311 toward the sewage outlet 321, a concentrated and powerful flow field is formed between them, driving and guiding the sewage and particulate matter along its path and in the surrounding area to move toward the sewage outlet 321, thus realizing active and guided sewage discharge. At the same time, the high pressure of the gas-liquid mixture effectively prevents stubborn stains and garbage from remaining at the bottom of the cleaning tank 32, thereby reducing bacterial growth and odor generation, and reducing the burden of subsequent cleaning.

[0096] In one possible implementation, the cleaning tray 30 is also provided with a filter element 35. The filter element 35 covers the sewage outlet 321.

[0097] Through the setting of the filter element 35, solid dirt generated during the cleaning process, such as food residue, hair, fibers, etc., will be intercepted by the filter element 35 in the cleaning tank 32, preventing these dirt from entering the sewage pipe, sewage pump 40 or more sophisticated sewage treatment unit, thus improving the reliability of the system. The filter element 35 allows liquid sewage to pass through smoothly while retaining solid waste on its surface, achieving preliminary solid-liquid separation and reducing the pollution load on the downstream sewage tank 50 or sewage pipe. Simultaneously, the collected solid waste can be more easily cleaned, simplifying the waste disposal process. All intercepted solid waste naturally collects on the surface of the filter element 35, forming a centralized waste collection point. After cleaning, the user does not need to process the entire cleaning tank 32; they only need to remove the filter element 35 and empty the waste from its surface, simplifying maintenance, making the cleaning process faster and cleaner, and optimizing the user experience.

[0098] In one possible implementation, the cleaning tray 30 is also provided with a sludge collection tank 36. The sludge collection tank 36 is connected to the cleaning tank 32, and the sewage outlet 321 is located in the sludge collection tank 36.

[0099] In one possible implementation, the bottom height of the sludge collection tank 36 is lower than the bottom height of the cleaning tank 32 to facilitate the inflow of sewage.

[0100] In one possible implementation, the filter element 35 is placed over the sludge collection tank 36.

[0101] By setting up a sludge collection tank 36 connected to the cleaning tank 32 and placing the sewage outlet 321 in the sludge collection tank 36, while making the bottom height of the sludge collection tank 36 lower than the bottom height of the cleaning tank 32, the sewage is automatically and centrally collected into the sludge collection tank 36 by utilizing the liquid level difference, thereby significantly improving the efficiency and thoroughness of sewage discharge. Furthermore, by placing the filter element 35 over the sludge collection tank 36, all sewage is centrally filtered before discharge, effectively intercepting dirt and preventing blockage of the drainage pipe and secondary pollution of the cleaning tank caused by backflow of dirt. In addition, this design concentrates dirt in the small area of ​​the sludge collection tank 36, greatly facilitating the cleaning and maintenance of the filter element 35 and reducing the maintenance burden on users.

[0102] In one possible implementation, a guide element 37 is also provided in the cleaning tank 32. The guide element 37 is located at the first nozzle.On both sides of 311, the direction of the cleaning liquid spray is guided.

[0103] By setting the guide members 37 on both sides of the first nozzle 311 in the cleaning tank 32, the direction of the cleaning liquid spray is actively guided, which can gather and guide the cleaning liquid flow sprayed from the nozzle to the area to be cleaned, significantly improving the concentration and impact of the cleaning energy, thereby improving the cleaning efficiency. And by precisely guiding the liquid flow direction, the uniformity and thoroughness of the cleaning can be ensured. The liquid flow guided by the guide member 37 is more focused and stable, reducing splashing and noise caused by liquid flow scattering and disordered impact, and improving the user experience. At the same time, the guide member 37 can also prevent the high-pressure liquid flow from causing unnecessary impact on other components in the cleaning tank 32, playing a protective role.

[0104] In one possible implementation, the cleaning tray 30 is also provided with a rolling member 38. The rolling member 38 is set near the cleaning tank 32 to facilitate the entry of the cleaning component into the cleaning tank 32.

[0105] By providing a rolling element 38 on the cleaning tray 30 near the cleaning tank 32, the insertion operation of the cleaning component is greatly optimized. The rolling element 38 transforms the sliding friction between the cleaning component and the cleaning tray 30 into rolling friction, making the pushing operation easier and more convenient, significantly improving ease of use. At the same time, it effectively avoids direct scratching between the bottom of the cleaning component and the surface of the cleaning tray 30, thereby preventing scratches and wear on both and extending the product's service life. In addition, the guiding effect of the rolling element 38 allows the cleaning component to move smoothly and accurately to the optimal cleaning position within the cleaning tank 32, improving the reliability of operation and the consistency of cleaning effect.

[0106] In one possible implementation, the exhaust port of the sewage pump 40 is connected to the air inlet 22 of the water storage tank 20 through an air inlet pipe 221.

[0107] By connecting the exhaust port of the sewage pump 40 to the air inlet 22, energy recycling is achieved. The compressed gas generated by the sewage pump 40 is usually discharged directly into the atmosphere after drainage, and its energy is wasted. By creatively using the exhaust gas of the sewage pump 40 as the air source for generating gas-liquid mixture in the water storage tank 20, there is no need to configure an independent air compressor or air pump for the water storage tank 20, which greatly improves the energy utilization efficiency of the entire system and reduces operating energy consumption. At the same time, eliminating the need for an independent air pump specifically for supplying air to the water storage tank 20 reduces the number of core components of the system, which not only reduces hardware and material costs, but also makes the internal space layout of the base station 100 more compact, which is conducive to the miniaturization and lightweight design of the product, and frees up more space for other functional modules.

[0108] In one possible implementation, the base station 100 also includes an air supply pump, which is connected to the air supply pump through the air inlet pipe 221 to supply air to the water storage tank 20.

[0109] In one possible implementation, the valve port of the control air inlet 22 is located on the water storage tank 20, or is located at the air inlet.On pipe 221, or on the vent of sewage pump 40, or on the output of air supply pump.

[0110] In one possible implementation, base station 100 also includes sewage tank 50. The sewage outlet of sewage pump 40 is connected to sewage tank 50 through sewage pipe. Specification 9 / 15 pages 12 CN 121445263 A

[0111] By setting sewage tank 50, the sewage generated during the cleaning process of base station 100 can be automatically collected into a special container for temporary storage, instead of being directly discharged into the sewer, giving the equipment freedom of use. Users do not need to install the equipment near the sewer interface, which greatly improves the flexibility of equipment placement and the convenience of use. After cleaning is completed, users only need to take out sewage tank 50 and dump it in one go, without having to deal with complicated pipelines or sewage residue inside the cleaning equipment.

[0112] In one possible implementation, base station 100 also includes clean water pump 60. The drain outlet of the clean water pump 60 is connected to the inlet 21 of the water storage tank 20 via the inlet pipe 211.

[0113] As an active water supply power source, the clean water pump 60 can provide the water storage tank 20 with a stable flow rate and constant pressure of liquid. Stable and controllable water intake is a prerequisite for generating a stable ratio and high-quality gas-liquid mixture. The clean water pump 60 ensures that the liquid level and fluid state in the water storage tank 20 can be kept optimal under any external water pressure fluctuations, so that the mixed fluid finally sprayed from the nozzle always has a consistent cleaning efficiency. With the clean water pump 60, the base station 100 no longer depends on the specific pressure of the external water source, so that the base station 100 can be flexibly adapted to a variety of usage environments, such as the difference in water supply pressure on different floors, or used in conjunction with water storage containers of different specifications, which greatly enhances the universality of the product and the user experience.

[0114] In one possible implementation, the valve of the control inlet 21 is located on the water storage tank 20, or on the water inlet pipe 211, or on the valve of the output end of the clean water pump 60.

[0115] In one possible implementation, the base station 100 also includes a clean water tank 70. The water inlet of the clean water pump 60 is connected to the clean water tank 70 through a clean water pipe.

[0116] With the built-in clean water tank 70, the base station 100 can be cleaned independently. Users only need to replenish the liquid in the clean water tank 70 periodically, without having to permanently connect the base station 100 to a tap as in traditional designs. This frees up the placement of the base station 100, allowing users to place it anywhere with a power outlet without considering whether there is a water source nearby, greatly increasing the flexibility of home layout.

[0117] In one possible implementation, the water inlet of the water pump 60 can also be directly connected to the water inlet faucet via a water pipe, or the water inlet 21 of the water storage tank 20 can be directly connected to the water inlet faucet via a water pipe.

[0118] Please also refer to Figure 5. In one possible implementation, the water storage tank 20 is provided with an exhaust port 26. The exhaust port 26 is connected to the water storage chamber 241 and is used to discharge the gas in the water storage chamber 241. The water storage tank 20 is provided with a sealing component. The sealing component is used to seal the exhaust port 26.

[0119] In the initial state, the sealing component seals the exhaust port 26, and the water storage tank 20 becomes a sealed container. When the air inlet 22 starts to introduce gas, since the exhaust port 26 is closed, the air pressure will be quickly established in the tank 24, so that the liquid and gas can be mixed immediately and efficiently to form a gas-liquid mixed fluid and be forcibly discharged from the outlet 23, ensuring that the cleaning function can respond quickly and start without delay, and realizing precise control of the gas-liquid mixing process. If it is necessary to stop or adjust the output of the mixed fluid, simply stop the air intake and open the exhaust port 26 to instantly release the internal pressure, realizing precise control of stopping and starting immediately.

[0120] The vent 26 and the sealing element constitute a simple, resettable pressure protection mechanism. If the control system malfunctions, such as continuous air intake at the air inlet 22 and blockage at the water outlet 23, causing an abnormal increase in internal pressure in the water storage tank 20, the vent 26 can be opened under a set pressure or actively opened by the control system to release pressure in a timely manner. This effectively prevents the water storage tank 20, connecting pipes, and other components from deforming or being damaged due to excessive pressure, thus improving the safety and durability of the entire system.

[0121] In one possible implementation, the cleaning tray 30 also includes an overflow pipe 261. The vent 26 is connected to the cleaning tank 32 through the overflow pipe 261.

[0122] When the sealing element fails to seal properly due to aging, wear, or manufacturing tolerances, water and gas will leak into the equipment, which can easily lead to short circuits, corrosion of metal parts, or bacterial growth. Overflow pipe 261 provides a drainage channel for leaks in water tank 20 (page 10 / 15, CN 121445263 A). By actively guiding leaked water and gas into cleaning tank 32, it prevents water accumulation inside the precision and dry equipment, protecting core components. Simultaneously, overflow pipe 261 can make latent faults visible, guiding users to perform timely maintenance. Users will observe unexplained water accumulation in cleaning tank 32 during non-cleaning periods, providing a clear fault indication signal that the sealing component may have failed and needs inspection or replacement. This allows users to take action before the problem worsens, avoiding more expensive repairs. Furthermore, the design of overflow pipe 261 greatly enhances the product's tolerance to manufacturing tolerances and wear, thereby improving overall reliability and service life.

[0123] In one possible implementation, the sealing component includes a floating component 27. The floating component 27 is used to float after the water tank 20 is filled with liquid to seal the vent 26.

[0124] The design of the floating component 27 utilizes the principle of buoyancy to achieve automatic control of the sealing. When the water level rises to full,When the water level drops, the floating component 27 automatically floats up under the action of buoyancy and blocks the vent 26; when the water level drops, the floating component 27 automatically falls down due to the decrease in buoyancy and opens the vent 26. The whole process is completely spontaneous and does not require the intervention of any electronic components such as sensors, controllers or solenoid valves, realizing powerless automation, simplifying the system architecture, and reducing costs and energy consumption. At the same time, compared with the electronic control scheme that relies on circuits, sensors and software programs, the purely mechanical float structure has almost no risk of electronic failure, program error or signal interference, and the working state is extremely stable. In addition, the floating component 27 has a simple structure, is not easy to be damaged, and has a very long service life, thereby significantly improving the maintenance-free operation cycle and long-term reliability of the entire water storage tank 20 module.

[0125] In some designs, the floating component 27 can be connected to a visible indicator rod, or the cover 25 itself is made of transparent or semi-transparent material. Users can intuitively judge the approximate water level in the water storage tank 20 by observing the position of the floating component 27, without the need for an additional electronic water level display, thus also having functionality.

[0126] Please refer to Figures 6 and 8 simultaneously. In one possible implementation, the vent 26 is located on the cover 25. A limiting member 251 is provided on the side of the cover 25 facing the water storage chamber 241. The limiting member 251 is opposite to the vent 26. The floating member 27 is movably connected to the limiting member 251.

[0127] By placing the vent 26 and the limiting member 251 on the cover 25, the venting channel, the floating sealing mechanism, and the motion guiding mechanism are all integrated on the cover 25, making it highly integrated and modular. This greatly simplifies the assembly process of the water storage tank 20, improves production efficiency, and reduces the steps of complex assembly inside the tank 24.

[0128] The setting of the limiting member 251 provides a precise vertical movement trajectory for the floating member 27 to float up and down, effectively preventing the floating member 27 from tilting, jamming or deviating during the floating or falling process, ensuring that the floating member 27 can accurately and correctly block the exhaust port 26 when floating, and improving the sealing reliability.

[0129] If the sealing mechanism of the floating member 27 fails, the entire cover 25 can be directly replaced, realizing rapid repair and reducing maintenance time and cost. At the same time, the design of the cover 25, such as the structure of the limiting member 251 and the size of the exhaust port 26, can be optimized and adjusted according to the performance requirements of the water storage tank 20 or the cleaning plate 30, without changing the structure of the box 24.

[0130] In one possible implementation, the water inlet 21, the air inlet 22 and the water outlet 23 are also respectively provided on the cover 25.

[0131] Please also refer to Figure 7. In one possible implementation, the floating member 27 includes a floating part 271 and a blocking part 272. The limiting member 251 is provided with a limiting groove 252. The floating part 271 is movably disposed in the limiting groove 252. The sealing part 272 is connected to the floating part 271 and faces the exhaust port 26.

[0132] By setting the floating part 27 as a floating part 271 and a sealing part 272, each part can be optimally designed in terms of its function, avoiding the limitations of a single part having to meet both buoyancy and sealing requirements. The core function of the floating part 271 is to sense buoyancy, so it can be specifically optimized for lightweight and large volume to have extremely high buoyancy sensitivity, and can respond quickly even with small changes in water level. The core function of the sealing part 272 is to achieve sealing, so soft and elastic materials can be selected and designed to perfectly match the shape of the vent 26 to ensure reliable sealing effect.

[0133] At the same time, the precise guidance of the limiting groove 252 ensures accurate alignment and reliability of the seal. The limiting groove 252 provides a stable movement path for the floating part 271, ensuring that the floating part 271 can only move in a preset direction and is ultimately transmitted to the sealing part 272 connected to the floating part 271. This ensures that the sealing part 272 can accurately and correctly press into or cover the exhaust port 26 each time it floats up, forming a uniform sealing surface and eliminating the risk of air leakage caused by tilting or misalignment. In addition, the limiting groove 252 can effectively prevent the floating part 27 from rolling, translating or rotating in complex water flow or bubble environment, ensuring the stable movement trajectory of the floating part 27, thereby ensuring the long-term stable operation of the system under different working conditions.

[0134] Furthermore, the floating part 271 and the sealing part 272 can be manufactured and replaced as two independent parts. If the seal 243 ages, only the sealing part 272 can be replaced without replacing the entire floating part 27, further reducing maintenance costs.

[0135] In one possible implementation, the sealing component includes an exhaust motor and a sensor. The sensor is used to sense the water level in the water tank 20, and the exhaust motor is located at the exhaust port 26. The exhaust motor is used to close the exhaust port 26 when the water level in the water tank 20 reaches a preset position.

[0136] By setting up the sensor and motor, precise and programmable control of the water level and the timing of venting can be achieved. The sensor, such as photoelectric or capacitive, can accurately and continuously monitor the water level, rather than triggering only at a fixed water level point like the floating component 27. This allows the control system to obtain richer water level information. Based on this, the closing timing of the exhaust port 26 can be freely set by the program. For example, it can be set to close the exhaust port 26 in advance when the water volume reaches 90% to start pre-pressurization, thereby achieving a faster system response speed and optimizing the timing control of the entire cleaning process.

[0137] Meanwhile, the electronic control scheme can achieve the separation of sensing, control, and execution. The sensor can be installed in the position most conducive to accurate water level measurement, and the exhaust motor can be installed in the position most conducive to sealing or spatial layout, such as the outside of the cover 25.Unlike the floating component 27, which requires mechanical linkage and concentration at a single point, the internal structure design of the water storage tank 20 is freed up, allowing engineers greater flexibility in layout. Furthermore, the electronic control scheme enhances the system's functional integration and intelligent potential. Continuous water level data provided by sensors can be easily integrated into the central control system of the base station 100, enabling a wealth of intelligent functions. For example: Real-time water level display: Accurately displaying the remaining water volume on the base station 100 panel or mobile APP. Water shortage warning and automatic water shut-off: Automatically stopping operation and alerting the user when the water level is detected to prevent the air pump from running dry. Fault diagnosis: Determining whether there is leakage or blockage in the system by analyzing whether the water level change matches the inlet / outlet flow rate.

[0138] Moreover, the electronic control scheme has fewer moving parts, and the driving force of the motor is usually much greater than the buoyancy, enabling it to more reliably overcome resistance and complete opening and closing actions, resulting in higher long-term reliability in complex water quality environments.

[0139] In one possible implementation, the sealing component can also be a solenoid valve directly installed in the exhaust port 26.

[0140] In one possible implementation, the housing 24 has a sealing groove 242 on the side facing the cover 25. The sealing groove 242 surrounds the opening of the water storage cavity 241. A sealing element 243 is provided in the sealing groove 242. A sealing edge 253 is provided on the side of the cover 25 facing the housing 24. The sealing edge 253 is located in the sealing groove 242 and abuts against the sealing element 243.

[0141] Through the cooperation of the sealing groove 242, the sealing element 243, and the sealing edge 253, when the cover 25 is pressed onto the box 24, the sealing edge 253 squeezes the sealing element 243 from one side. At the same time, the side wall and bottom wall of the sealing groove 242 also cooperate to compress the sealing element 243, thereby forming a more effective sealing interface on the sealing element 243. The sealing groove 242 constitutes a confined space. Even if a small amount of liquid breaks through the initial sealing surface, it will be blocked in the labyrinthine sealing groove 242, making it difficult to continue to leak. This achieves a multiple sealing effect and greatly improves the reliability of the seal. At the same time, the sealing groove 242, as a precise positioning base, can ensure that the sealing element 243, such as the O-ring, is accurately placed in the designed position during the assembly process, preventing it from shifting, twisting, or falling off during installation, and ensuring the consistency of assembly quality. The sealing groove 242 also protects the sealing element 243 therein, preventing accidental scratches, cuts or wear during handling, installation or use, thereby extending the service life of the sealing element 243.

[0142] Since the main sealing function is undertaken by the elastic sealing element 243, the requirements for the flatness and smoothness of the contact surfaces of the housing 24 and the cover 25 can be appropriately relaxed, reducing the processing difficulty and manufacturing cost of the parts, while improving the production efficiency.The yield rate of the product. In addition, the sealing groove 242 and sealing edge 253 surrounding the opening of the water storage cavity 241 actually form a reinforcing rib on the box body 24 and the cover body 25 respectively. When the water storage tank 20 is pressurized, this structure can better resist the deformation caused by the pressure, prevent the seal from being damaged due to the "bulging" of the central area of ​​the cover plate, and ensure the integrity of the seal under the working pressure.

[0143] In one possible implementation, the water storage tank 20 also includes an extension pipe 28. The extension pipe 28 is located in the water storage cavity 241. One end of the extension pipe 28 is connected to the outlet 23, and the other end is located at the bottom of the water storage cavity 241.

[0144] The inlet of the extension pipe 28 is located at the lowest point of the water storage cavity 241, which makes the liquid in the water storage tank 20 almost completely usable. Even if the water level is very low, as long as the pipe opening of the extension pipe 28 is submerged, the system can continue to draw liquid for operation. Meanwhile, when gas is introduced into the air inlet 22 for pressurization, a gas-liquid mixture zone rich in bubbles will be formed in the upper part of the water storage chamber 241. The extension tube 28 is drawn from the bottom, and the lower layer of mixed fluid with higher liquid content and density is drawn first, which can ensure that the output fluid has sufficient liquid quality and impact force, avoiding the problems of too much air and too little water, weak output or instability that may be caused by drawing directly from the top, thereby ensuring the stability and effectiveness of the rinsing effect.

[0145] The base station 100 provided in this application embodiment is applied to a cleaning system. The base station 100 includes a water storage tank 20 and a cleaning tray 30. The water storage tank 20 is provided with a water inlet 21, an air inlet 22 and a water outlet 23. The water inlet 21 is used to introduce liquid into the water storage tank 20. The air inlet 22 is used to introduce gas into the water storage tank 20 to form a gas-liquid mixed fluid in the water storage tank 20. The water outlet 23 is used to output the gas-liquid mixed fluid. The cleaning tray 30 is provided with a spray nozzle 31. The spray nozzle 31 is connected to the outlet 23 of the water tank 20 through the outlet pipe 231, which is used to inject the gas-liquid mixture into the cleaning tray 30 to rinse the cleaning tray 30.

[0146] By setting the inlet 21 and the air inlet 22 in the water tank 20, a gas-liquid mixture can be formed in the water tank 20, and the cleaning tray 30 is automatically rinsed through the outlet 23, the outlet pipe 231 and the spray nozzle 31. By using a gas-liquid mixture containing a large number of bubbles, when impacting the surface of the cleaning tray 30, the bubbles break and generate a stronger local impact force and turbulence effect, thereby more effectively removing stubborn stains adhering to the gaps and grooves of the cleaning tray 30, achieving a deeper and more thorough cleaning of the cleaning tray 30, preventing the long-term accumulation of dirt from the source, significantly reducing the problems of bacterial growth and odor generation, and ensuring the hygiene and health of the home environment. Furthermore, by using a high-pressure gas-liquid mixture to impact and remove waste from a designated area, it is ensured that the cleaning disc 30 returns to a clean state after each cleaning cycle, preventing [the spread of the contaminant].This avoids cross-contamination of dirt and prevents secondary contamination of the main unit's roller brush due to unclean cleaning disc 30. Simultaneously, this process is entirely automated by the base station 100, requiring no manual intervention from the user, fundamentally solving the problem of users being unwilling to clean due to the tedious cleaning process, thus improving the user experience and sense of well-being.

[0147] This application also provides a base station cleaning method, applied to a cleaning system. The cleaning system includes a base station 100. The base station cleaning method includes:

[0148] Supplying liquid to the water storage tank 20 to fill it.

[0149] Specifically, by starting the clean water pump 60, water from the clean water tank 70 is injected into the water storage tank 20 until it is full. At this time, the sealing component seals the vent 26 of the water storage tank 20, forming a closed space.

[0150] Simultaneously supplying liquid and gas to the water storage tank 20 to pressurize it, forming a gas-liquid mixture within the water storage tank 20.

[0151] Specifically, the clean water pump 60 and the sewage pump 40 are started simultaneously. While the sewage pump 40 is pumping out sludge, the exhaust gas from the sewage pump 40 is connected to the water storage tank 20 to pressurize the water storage tank 20.

[0152] The gas-liquid mixture is injected into the cleaning plate 30 through the spray nozzle 31 to rinse the cleaning plate 30. Specification 13 / 15 pages 16 CN 121445263 A

[0153] Specifically, by activating the valve port provided at the outlet 23, the outlet pipe 231, or the first end of the first three-way pipe 33, the pressurized gas-liquid mixture in the water storage tank 20 flows through the outlet pipe 231 to the spray nozzle 31, and is sprayed into the cleaning tank 32 through the spray nozzle 31 to achieve rinsing of the cleaning plate 30.

[0154] By supplying liquid to the water storage tank 20 and simultaneously supplying liquid and gas to the water storage tank 20, a gas-liquid mixture is formed in the water storage tank 20. When the gas-liquid mixture containing a large number of bubbles is ejected at high speed from the spray nozzle 31, the bubbles will instantly collapse when they come into contact with the surface of the cleaning plate 30 or the water flow, releasing micro-jet streams and shock waves, generating strong local shear force. This force, combined with the impact force of the water flow itself, can more effectively peel off and crush stubborn stains. Its cleaning ability far exceeds that of pure water rinsing at the same flow rate and pressure.

[0155] At the same time, because the cleaning efficiency of the gas-liquid mixture is higher, the amount of water required to achieve the same level of cleanliness can be significantly reduced, achieving better cleaning results with lower water consumption, which is energy-saving and environmentally friendly. This process is completely completed automatically by the base station 100 without manual handling by the user, fundamentally solving the problem that users are unwilling to clean due to the cumbersome cleaning process, and improving the user experience and sense of well-being.

[0156] In one possible implementation, the step of injecting a gas-liquid mixture into the cleaning pan 30 through the spray nozzle 31 to rinse the cleaning pan 30 includes:

[0157] The gas-liquid mixture is sprayed out relative to each other through two second nozzles 312 to rinse the two sides of the cleaning pan 30, causing the wastewater to concentrate in the middle of the cleaning pan 30.

[0158] Specifically, by closing the valve, the gas-liquid mixture is first sprayed out through the second nozzles 312 to rinse the two sides of the cleaning tank 32.

[0159] The gas-liquid mixture is sprayed out through the first nozzle 311 to the middle of the cleaning pan 30 to rinse the middle area of ​​the cleaning pan 30.

[0160] Specifically, the valve is opened to spray out the gas-liquid mixture through the first nozzle 311 to rinse the middle area of ​​the cleaning tank 32 and flush the wastewater to the wastewater outlet 321.

[0161] The wastewater collected in the middle of the cleaning pan 30 is pumped out by the wastewater pump 40.

[0162] Specifically, the wastewater pump 40 pumps the wastewater at the wastewater outlet 321 into the wastewater tank 50.

[0163] Through the second nozzles 312 located on both sides of the cleaning pan 30 with opposite water outlet directions, the gas-liquid mixture is sprayed from both sides in opposite directions, forming a clean water flow covering the sidewalls and edge areas of the cleaning pan 30. This effectively washes away the dirt attached to the sidewalls and uses the kinetic energy of the fluid counter-current to drive the dirt from both sides toward the center area of ​​the cleaning pan 30. At the same time, the first nozzle 311 located in the middle is responsible for concentrated rinsing of the center area of ​​the cleaning pan 30, ensuring that every area from the edge to the center can be rinsed, eliminating cleaning dead corners. The first nozzle 311 further agitates and suspends the dirt gathered there. The water inlet of the sewage pump 40 is directly connected to the middle of the cleaning pan 30, so that the sewage and dirt gathered in the middle can be pumped away by the sewage pump 40 in a timely and efficient manner, greatly reducing the residence time of sewage in the cleaning pan 30. This prevents the sewage after rinsing from being deposited again or contaminating the cleaned surface due to failure to be discharged in time, thereby eliminating secondary pollution and ensuring the final cleaning effect.

[0164] In one possible implementation, the base station cleaning method is continuous cleaning, in which the cleaning tray 30 is continuously rinsed by a gas-liquid mixed fluid.

[0165] In one possible implementation, the base station cleaning method is intermittent cleaning, in which the cleaning tray 30 is cleaned by a gas-liquid mixed fluid in stages.

[0166] In one possible implementation, the base station cleaning method further includes:

[0167] After rinsing the cleaning tray 30 for a predetermined time, venting the water tank 20 by activating the sealing component. Specification 14 / 15 pages 17 CN 121445263 A

[0168] Specifically, the predetermined time can be a factory setting or set by the program of the base station 100.

[0169] Liquid is supplied to the water tank 20 again to fill the water tank 20, and then the above rinsing process is repeated.

[0170] By using intermittent rinsing, the cleaning efficiency can be improved. After the first rinse, the upper part of the water tank 20 is full.Compressed gas is used. If liquid is injected directly, this gas will be compressed violently, forming extremely high pressure, which may exceed the system's safety range or cause difficulty in water injection. First, the sealing component is activated to vent the gas, which is equivalent to restoring the water storage tank 20 to normal pressure, creating a standard and controllable initial condition for the next water injection, ensuring that the same liquid level and pressure state is achieved each time water is injected, thereby ensuring that the intensity and effect of each flush are stable and reliable. At the same time, if the gas is not vented, the existing compressed gas in the water storage tank 20 will occupy a large amount of space, resulting in a significant reduction in the actual amount of liquid that can be injected, which will shorten the duration of the next flush and may not be able to complete a thorough cleaning.

[0171] Through the closed-loop process of flushing-venting-water replenishment, a complete cycle is formed, enabling the base station to repeatedly perform the flushing process to achieve intermittent flushing.

[0172] This application also provides a cleaning system, including cleaning equipment and the above-mentioned base station 100.

[0173] In one possible implementation, the cleaning system may also apply the above-mentioned base station cleaning method.
