Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a base station, a base station cleaning method, and a cleaning system. Background Technology

[0002] With the continuous development of smart home technology, cleaning devices with self-cleaning functions are becoming increasingly popular. These devices are typically equipped with a base station for charging the main unit, replenishing fresh water, recycling wastewater, and cleaning the roller brush. The base station usually contains a cleaning tray to support the roller brush and other components of the main unit.

[0003] Currently, the cleaning discs of base stations are not removable and the cleaning process is cumbersome, making it inconvenient to clean the discs. This results in low user willingness to clean them, and the discs are prone to accumulating dirt and grime, leading to bacterial growth, odors, and other adverse effects on user health. Summary of the Invention

[0004] This application provides a base station, a base station cleaning method, and a cleaning system to automatically and efficiently clean the base station cleaning tray, thereby effectively improving hygiene and user experience.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a base station for use in a cleaning system, the base station comprising:

[0007] Clean water tank;

[0008] The water storage tank is equipped with a water inlet, an air inlet, and a water outlet, all controlled by valves. The water inlet is used to connect 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 inside the water storage tank. The water outlet is used to output the gas-liquid mixture.

[0009] The cleaning tray is equipped with a water spray nozzle, which is connected to the outlet of the water storage tank through a water outlet pipe. This nozzle is used to inject a gas-liquid mixture into the cleaning tray to rinse it.

[0010] As an optional implementation, the base station also includes a sewage pump. The spray nozzle includes a first nozzle and two second nozzles. The two second nozzles are respectively located on both sides of the cleaning pan and are arranged in opposite directions to spray the gas-liquid mixture into the areas on both sides of the cleaning pan. The first nozzle is located in the middle of the cleaning pan and is used to spray the gas-liquid mixture into the middle area of ​​the cleaning pan. The pump inlet of the sewage pump is connected to the middle of the cleaning pan and is used to extract the sewage collected in the middle of the cleaning pan.

[0011] As an optional implementation, the base station also includes a first three-way pipe and a second three-way pipe. The first end of the first three-way pipe is connected to the water outlet, the second end of the first three-way pipe is connected to the first end of the second three-way pipe, the third end of the first three-way pipe is connected to the first nozzle, the second end of the second three-way pipe is connected to one of the second nozzles, and the third end of the second three-way pipe is connected to the other second nozzle.

[0012] As an optional implementation, the vent of the sewage pump is connected to the air inlet of the water storage tank through an air inlet pipe.

[0013] As an optional implementation, the base station also includes a water pump, the drain outlet of which is connected to the inlet of the water storage tank via an inlet pipe.

[0014] As an optional implementation, the base station also includes a clean water tank, and the water pump's intake port is connected to the clean water tank via a clean water pipe.

[0015] As an optional implementation, the water storage tank is provided with an exhaust port, and a sealing element is provided in the water storage tank to seal the exhaust port.

[0016] This application provides a base station cleaning method, applied in a cleaning system. The cleaning system includes a base station; the base station includes a water tank and a cleaning tray, the cleaning tray is provided with a water spray nozzle, and the water spray nozzle is connected to the water tank. The base station cleaning method includes:

[0017] Supply liquid into the water tank to fill it;

[0018] Liquid and gas are supplied to the water storage tank simultaneously to pressurize the tank and form a gas-liquid mixture inside.

[0019] A gas-liquid mixture is injected into the cleaning pan through a spray nozzle to rinse the pan.

[0020] As an optional implementation, the base station also includes a sewage pump, and the spray nozzle includes a first nozzle and two second nozzles. The two second nozzles are respectively located on both sides of the cleaning plate and the water outlet directions are opposite to each other. The first nozzle is located in the middle of the cleaning plate.

[0021] The steps of injecting a gas-liquid mixture into the cleaning tray through a spray nozzle to rinse the cleaning tray include:

[0022] The gas-liquid mixture is sprayed out relative to each other through two second nozzles to rinse the two sides of the cleaning pan, causing the wastewater to concentrate in the middle of the cleaning pan.

[0023] The gas-liquid mixture is sprayed through the first nozzle to the center of the cleaning pan to rinse the central area of ​​the cleaning pan.

[0024] The wastewater collected in the middle of the cleaning pan is pumped out using a wastewater pump.

[0025] As an optional implementation, the water storage tank is equipped with a sealing device, and the base station cleaning method also includes:

[0029] The base station, base station cleaning method, and cleaning system provided in this application, by setting water inlets and air inlets in the water storage tank, can form a gas-liquid mixture in the water storage tank, and automatically rinse the cleaning tray through the water outlet, water outlet pipe, and spray nozzle. By using a gas-liquid mixture containing a large number of air bubbles, when impacting the surface of the cleaning tray, the bursting of the air bubbles generates a stronger local impact force and turbulence effect, thereby more effectively removing stubborn stains adhering to the gaps and grooves of the cleaning tray, achieving a deeper and more thorough cleaning of the cleaning tray, preventing 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 away through the high-pressure gas-liquid mixture, it can be ensured that the cleaning tray is 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. Meanwhile, this process is completed entirely automatically by the base station, without the need for manual intervention by the user. This fundamentally solves the problem that users are unwilling to clean due to the tedious cleaning process, thus improving the user experience and sense of well-being. Attached Figure Description

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 only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features 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. These devices are typically equipped with a base station for charging the main unit, replenishing fresh water, recycling wastewater, and cleaning the roller brush. The base station usually contains a cleaning tray to support the roller brush and other components of the main unit.

[0045] Currently, the cleaning discs of base stations are not removable and the cleaning process is cumbersome, making it inconvenient to clean the discs. This results in low user willingness to clean them, and the discs are prone to accumulating dirt and grime, leading to bacterial growth, odors, and other adverse effects on user health.

[0046] In order to overcome the shortcomings of the existing technology, after repeated thinking and verification, the inventors discovered that if water spray nozzles are set on the cleaning plate, the cleaning plate can be automatically cleaned by rinsing with high-pressure water. This can achieve efficient removal of dirt without disassembling the cleaning plate, thereby preventing the long-term accumulation of dirt, reducing the problems of bacterial growth and odor, and improving the user experience and sense of well-being.

[0047] In view of this, this application provides a base station for use in a cleaning system, the base station comprising:

[0048] Clean water tank;

[0049] The water storage tank is equipped with a water inlet, an air inlet, and a water outlet, all controlled by valves. The water inlet is used to connect 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 inside the water storage tank. The water outlet is used to output the gas-liquid mixture.

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

[0051] By incorporating water and air inlets in the water tank, a gas-liquid mixture is formed within the tank. This mixture is then automatically flushed through the outlet, water pipe, and spray nozzles. The gas-liquid mixture, containing numerous air bubbles, generates a stronger local impact and turbulence effect upon impacting the cleaning tray surface. This effectively removes stubborn stains adhering to the crevices and grooves of the cleaning tray, achieving a deeper and more thorough cleaning. This prevents long-term buildup of dirt, significantly reducing bacterial growth and odor issues, thus ensuring a hygienic and healthy home environment. Furthermore, by using the high-pressure gas-liquid mixture to impact and remove debris from designated areas, the cleaning tray is restored to a clean state after each cleaning cycle, preventing cross-contamination and avoiding secondary pollution of the main unit's roller brush due to an unclean cleaning tray. This entire process is completed automatically by the base station, requiring no manual intervention from the user. This fundamentally solves the problem of users being reluctant to clean due to tedious processes, improving the user experience and overall satisfaction.

[0052] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

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

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

[0056] Cleaning equipment is used in home life to automatically clean the house and is suitable for cleaning selected areas, saving time and effort and freeing up human hands.

[0057] In one possible implementation, the cleaning device can be a robotic vacuum cleaner. However, it is not limited to this; in other possible implementations, the cleaning device can also be a combined sweeping and mopping robot, or other mobile cleaning devices that meet 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 cleaning equipment.

[0059] Please also refer to Figure 3 The water storage tank 20 provided in this embodiment is equipped with an inlet 21, an air inlet 22, and an outlet 23, all controlled by valves. The inlet 21 connects to the clean water tank 70 of the cleaning system to introduce liquid into the water storage tank 20. The air inlet 22 introduces gas into the water storage tank 20 to pressurize it, causing the gas and liquid to mix and form a gas-liquid mixture, which is the cleaning liquid used to clean the cleaning tray 30. The outlet 23 outputs the gas-liquid mixture to rinse the area to be cleaned. The valves control the opening and closing of the corresponding openings on the water storage tank 20, allowing the water storage tank 20 to switch between a closed and open state.

[0060] In one possible implementation, the liquid in the cleaning liquid can be a cleaning solution, clean water, or a mixture of clean water, such as 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, an inert gas (such as nitrogen or argon), or other gaseous media suitable for the cleaning process.

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

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

[0063] The water 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. It can achieve gas-liquid mixing and is a portable module, allowing the water tank 20 to 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 tank 20.

[0064] Meanwhile, the water storage tank 20, designed specifically for generating gas-liquid mixtures, has a single function, ensuring a continuous output of uniformly mixed and pressure-stable gas-liquid mixtures, thus providing reliable and efficient performance 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 equipped with a water spray nozzle 31. The water spray nozzle 31 is connected to the water 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 water 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. A water spray nozzle 31 is provided in the cleaning tank 32 for injecting cleaning liquid, i.e., a gas-liquid mixture, into the cleaning tank 32 to rinse the cleaning tank 32.

[0067] By integrating the cleaning tank 32 and the spray nozzle 31 into a separate cleaning tray 30, the cleaning tray 30 can clean the cleaning tank 32 through the independently designed spray nozzle 31, thus 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 entire base station 100, improves production efficiency, and also provides a standardized interface and replacement basis for different models and capacities of cleaning trays 30 that may appear in the future.

[0068] Furthermore, since the cleaning disc 30 is the core area for dirt accumulation and the component most in need of cleaning or replacement, designing it as an independent component allows users or maintenance personnel to directly replace the cleaning disc 30 individually when it ages, becomes damaged, or requires deep cleaning due to long-term use, without having to disassemble or replace the entire base station 100. This greatly reduces maintenance costs and difficulty, and improves the 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 rinse the cleaning tray 30 through the water outlet 23, the water outlet pipe 231 and the water spray nozzle 31. This process is completely completed automatically by the base station 100 without manual handling by the user. Thus, even when the cleaning tray is not removable, it fundamentally solves the problem of users being unwilling to clean due to the cumbersome cleaning process, thereby improving the user experience and sense of well-being.

[0070] Utilizing a gas-liquid mixture containing numerous air bubbles, the cleaning disc 30 experiences a stronger localized impact force and turbulence effect upon impact with its surface. This more effectively removes stubborn stains adhering to the crevices and grooves of the cleaning disc 30, achieving a deeper and more thorough cleaning. This prevents long-term buildup of dirt from the source, significantly reducing bacterial growth and odor issues, and ensuring a hygienic and healthy home environment. Furthermore, by using a high-pressure gas-liquid mixture to impact and remove waste to designated areas, the cleaning disc 30 is ensured to return to a clean state after each cleaning cycle, preventing cross-contamination and avoiding secondary contamination of the main unit's roller brush due to an unclean cleaning disc 30.

[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 24 has a water storage cavity 241. The cover 25 covers 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 tank 20. Over long-term use, scale or microbial film may accumulate on the inner wall of the water tank 20. By opening the cover 25, users or service personnel can easily perform thorough manual cleaning, descaling, or disinfection of the interior of the water storage chamber 241, greatly improving the maintainability and cleaning convenience of the water tank 20. This effectively prevents blockage of the outlet 23 or secondary pollution caused by internal contamination, ensuring the long-term hygiene and operational stability of the system.

[0073] Meanwhile, the water tank 20 is divided into two main components: the tank body 24 and the cover 25. This simplifies mold design and injection molding processes, making the production of the water tank 20 more efficient and achieving a higher yield rate. This structure also facilitates the installation of other built-in components, such as water level sensors and baffles, inside the tank body 24, simplifying production assembly. The independent cover 25 provides a uniform, reliable, and repeatedly openable and closable sealing interface, allowing for restoration of sealing performance after maintenance. Furthermore, in case of poor sealing, only the low-cost sealing ring or cover 25 needs to be replaced, eliminating the need to replace the entire water tank 20 assembly and reducing subsequent 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 located on both sides of the cleaning pan 30, with their water outlet directions opposite to each other, for spraying the gas-liquid mixture towards the areas on both sides of the cleaning pan 30. The first nozzle 311 is located in the middle of the cleaning pan 30, for spraying the gas-liquid mixture into the central area of ​​the cleaning pan 30. The 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 waste is collected in the middle of the washing plate 30.

[0076] In one possible implementation, two second nozzles 312 are respectively disposed on both sides of the cleaning tank 32, with their water outlet directions opposite to each other. These nozzles spray cleaning liquid onto the sides of the cleaning tank 32 to rinse both sides and allow the rinsed wastewater to flow towards the center of the cleaning tank 32. A first nozzle 311 is disposed in the center of the cleaning tank 32, spraying cleaning liquid into the central area to rinse the center of the cleaning tank 32. This nozzle also works in conjunction with the wastewater pump 40 to extract the rinsed wastewater.

[0077] Through the second nozzles 312 positioned on both sides of the cleaning pan 30 with opposite water outlet directions, a gas-liquid mixture is sprayed from both sides, forming a clean water flow covering the sidewalls and edges of the cleaning pan 30. This effectively washes away dirt adhering to the sidewalls and uses the kinetic energy of the fluid counter-current to drive the dirt from both sides towards the center of the cleaning pan 30. Simultaneously, the first nozzle 311 located in the center is responsible for concentrated rinsing of the central area of ​​the cleaning pan 30, ensuring that every area from the edge to the center is rinsed, eliminating cleaning dead zones. The first nozzle 311 further agitates and suspends the dirt gathered there. The inlet of the wastewater pump 40 is directly connected to the center of the cleaning pan 30, allowing the wastewater and dirt concentrated in the center to be pumped away by the wastewater pump 40 immediately and efficiently. This greatly reduces the residence time of wastewater in the cleaning pan 30, preventing the wastewater from redepositing or contaminating the cleaned surface due to failure to be discharged in time, thus 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 pan 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 from the water storage tank 20, i.e., a 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 structure can be used to distribute water from one inlet 21 to three nozzles. This simplifies the structure and assembly complexity of the piping system compared to laying a separate inlet pipe 211 for each nozzle, and achieves efficient and simplified distribution of water from a single inlet to multiple spray nozzles.

[0081] Simultaneously, the first three-way pipe 33 performs a primary diversion, supplying the first nozzle 311 and the entire second branch. Then, the second three-way pipe 34 performs a secondary diversion, supplying the two second nozzles 312. For the two second nozzles 312 after the second three-way pipe 34, it can be ensured that the water flow rate and pressure they receive are similar, thereby ensuring that the spraying effect at different positions on the cleaning plate 30 has good consistency and 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 for controlling the outlet 23 is located on the water storage tank 20, or on the outlet pipe 231 between the first three-way pipe 33 and the outlet 23, or on 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 tee 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 pressurized cleaning liquid first flows 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 flush away the dirt and debris scattered on both sides and bring them towards the center. In the second stage, after rinsing both sides is completed, the valve opens, and the first nozzle 311 begins to work, rinsing the central area. The wastewater pump 40 then removes the wastewater that has gathered in the center. The valve can be opened by a timer or controlled by a pressure sensor. This time-sequential rinsing avoids the possibility of scattering debris from the center to the corners in the initial rinsing stage. Through orderly fluid guidance, it ensures that the debris is effectively concentrated and ultimately removed.

[0085] Simultaneously, in the initial stage, closing the branch of the first nozzle 311 allows all the water flow and pressure to be concentrated on the two second nozzles 312, maximizing their flushing kinetic energy and ensuring sufficient cleaning power for the areas on both sides. When the valve opens and the first nozzle 311 begins operation, the system pressure is redistributed. Since the debris on both sides has been flushed out and driven to the middle, the second nozzles 312 do not require extremely high pressure to complete the flushing, while the first nozzle 311 has greater kinetic energy to clean the middle area. This achieves on-demand distribution of the gas-liquid mixture pressure in the water tank 20, ensuring the flushing intensity at each stage.

[0086] In one possible implementation, the cleaning pan 30 also includes a four-way pipe. The first end of the four-way pipe is connected to the outlet 23 for connecting the cleaning liquid, i.e., the gas-liquid mixture, flowing from the water tank 20. 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 tee pipe 33 and the second tee pipe 34 with a single four-way pipe reduces the core components of the shunt system from two to one. This simplifies the piping complexity and the number of parts, reduces connection points, lowers the potential risk of leakage, and improves assembly efficiency and production consistency. The space occupied by a single four-way pipe is typically less than that required by two tee pipes and their connecting pipes, freeing up more valuable design space within the base station 100 for facilitating the placement of other components or achieving a more compact product design.

[0088] Meanwhile, compared to two tandem T-junctions, the flow path within a single four-way pipe is typically more direct and smoother. Water entering from the inlet only needs one branching step to reach the three outlets, whereas a tandem T-junction requires two. This reduces changes in water flow direction and impact, thus lowering pressure loss in the entire branching system. Under the same inlet pressure, it can provide a larger total flow rate to the three nozzles, or consume less pumping power to achieve the same flow rate.

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

[0090] 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 drives the two second nozzles 312 to powerfully rinse the two sides of the cleaning disc 30. The purpose of this stage is to wash away the dirt and debris scattered on the sides and bring them towards the center. In the second stage, after the sides have been rinsed, the valve opens, and the first nozzle 311 starts working to rinse the central area. The wastewater pump 40 then removes the wastewater that has gathered in the center. The valve can be opened by a timer or controlled by a pressure sensor. This time-sequential rinsing avoids the possibility of scattering debris from the center to the corners in the initial rinsing stage. Through orderly fluid guidance, it ensures that the debris is effectively concentrated and ultimately removed.

[0091] Simultaneously, in the initial stage, closing the branch of the first nozzle 311 allows all the water flow and pressure to be concentrated on the two second nozzles 312, maximizing their flushing kinetic energy and ensuring sufficient cleaning power for the areas on both sides. When the valve opens and the first nozzle 311 begins operation, the system pressure is redistributed. Since the debris on both sides has been flushed out and driven to the middle, the second nozzles 312 do not require extremely high pressure to complete the flushing, while the first nozzle 311 has greater kinetic energy to clean the middle area. This achieves on-demand distribution of the gas-liquid mixture pressure in the water tank 20, ensuring the flushing intensity at each stage.

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

[0093] Please also refer to Figure 9 In one possible implementation, the cleaning tray 30 is further provided with a wastewater outlet 321. The wastewater outlet 321 is opposite to the first nozzle 311. The wastewater outlet 321 is used to collect wastewater in the cleaning tank 32. The wastewater outlet 321 is connected to the suction port of the wastewater 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 to transport 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 jet is ejected from the first nozzle 311 towards the sewage outlet 321, a concentrated and powerful flow field is formed between them. This flow field drives and guides the sewage and particulate matter along its path and in the surrounding area, causing them to move towards the sewage outlet 321, thus achieving active and guided sewage discharge. At the same time, the high pressure of the gas-liquid mixture effectively prevents stubborn stains and debris from remaining at the bottom of the cleaning tank 32, thereby reducing bacterial growth and odor generation, and lowering the burden of subsequent cleaning.

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

[0097] By incorporating filter element 35, solid waste generated during the cleaning process, such as food scraps, hair, and fibers, is intercepted within the cleaning tank 32, preventing it from entering the sewage pipe, sewage pump 40, or more sophisticated sewage treatment units, thus improving system reliability. Filter element 35 allows liquid wastewater to pass through smoothly while retaining solid waste on its surface, achieving preliminary solid-liquid separation and reducing the pollution load on downstream sewage tank 50 or drain pipes. Simultaneously, the collected solid waste is easier to clean, simplifying the waste disposal process. All intercepted solid waste naturally collects on the surface of filter element 35, forming a centralized waste collection point. After cleaning, users do not need to dispose of the entire cleaning tank 32; they only need to remove 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 further provided with a sludge collection tank 36. The sludge collection tank 36 is connected to the cleaning tank 32, and the wastewater outlet 321 is located in the sludge collection tank 36.

[0099] In one possible implementation, the bottom of the sludge collection tank 36 is lower than the bottom 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 within the sludge collection tank 36, while ensuring the bottom of the sludge collection tank 36 is lower than the bottom of the cleaning tank 32, the sewage is automatically and centrally collected into the sludge collection tank 36 using the liquid level difference, thus significantly improving the efficiency and thoroughness of sewage discharge. Furthermore, a filter element 35 is placed over the sludge collection tank 36, ensuring that all sewage is centrally filtered before discharge, effectively intercepting contaminants and preventing blockage of the drainage pipes and secondary pollution of the cleaning tank caused by backflow of contaminants. In addition, this design concentrates contaminants within the small area of ​​the sludge collection tank 36, greatly facilitating the cleaning and maintenance of the filter element 35 and reducing the user's maintenance burden.

[0102] In one possible implementation, the cleaning tank 32 is further provided with a flow guide 37. The flow guide 37 is located on both sides of the first nozzle 311 to guide the spray direction of the cleaning liquid.

[0103] By installing 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. This concentrates the cleaning liquid stream from the nozzle and directs it to the area to be cleaned, significantly improving the concentration and impact of the cleaning energy, thereby enhancing cleaning efficiency. Furthermore, precise guidance of the liquid flow direction ensures uniformity and thoroughness of the cleaning. The liquid flow guided by the guide members 37 is more focused and stable, reducing splashing and noise caused by liquid scattering and disordered impacts, thus improving the user experience. Simultaneously, the guide members 37 also prevent the high-pressure liquid flow from causing unnecessary impact on other components within the cleaning tank 32, providing protection.

[0104] In one possible implementation, the cleaning tray 30 is further provided with a roller 38. The roller 38 is positioned adjacent to the cleaning tank 32 to facilitate the entry of the cleaning components into the cleaning tank 32.

[0105] By incorporating a rolling element 38 on the cleaning tray 30 adjacent to the cleaning tank 32, the insertion of cleaning components is significantly optimized. The rolling element 38 transforms the sliding friction between the cleaning component and the cleaning tray 30 into rolling friction, making the insertion effortless and convenient, thus significantly improving ease of use. Simultaneously, it effectively prevents 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 product lifespan. Furthermore, the guiding effect of the rolling element 38 allows the cleaning component to move smoothly and precisely position itself within the cleaning tank 32 for optimal cleaning, improving operational reliability and the consistency of cleaning results.

[0106] In one possible implementation, the vent of the sewage pump 40 is connected to the air inlet 22 of the water storage tank 20 via 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 typically discharged directly into the atmosphere after drainage, wasting its energy. By creatively using the exhaust gas from the sewage pump 40 as the gas source for generating the gas-liquid mixture in the water storage tank 20, there is no need to configure an independent air compressor or pump for the water storage tank 20, greatly improving the energy efficiency of the entire system and reducing operating energy consumption. At the same time, eliminating the need for a separate air pump to supply air to the water storage tank 20 reduces the number of core components in the system, lowering hardware and material costs. It also allows for a more compact internal layout of the base station 100, facilitating miniaturization and lightweight design, and freeing up more space for other functional modules.

[0108] In one possible implementation, the base station 100 also includes an air supply pump connected via an air inlet pipe 221, thereby supplying air into 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 on the air inlet pipe 221, or on the exhaust port of the sewage pump 40, or on the output end of the air supply pump.

[0110] In one possible implementation, the base station 100 also includes a sewage tank 50. The sewage outlet of the sewage pump 40 is connected to the sewage tank 50 via a sewage pipe.

[0111] The wastewater tank 50 automatically collects the wastewater generated during the cleaning of the base station 100 into a dedicated container for temporary storage, instead of discharging it directly into the sewer. This provides greater flexibility in equipment use, eliminating the need for users to install the equipment near sewer inlets, significantly improving placement flexibility and ease of use. After cleaning, users simply remove the wastewater tank 50 for a one-time, centralized emptying, eliminating the need to deal with complex piping or residual wastewater inside the cleaning equipment.

[0112] In one possible implementation, the base station 100 also includes a 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 an inlet pipe 211.

[0113] As a power source for active water supply, the clean water pump 60 provides 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 within the water storage tank 20 remain optimal under any external water pressure fluctuations, thus ensuring that the mixed fluid ultimately ejected from the nozzle always has consistent cleaning performance. With the clean water pump 60, the base station 100 no longer relies on the specific pressure of an external water source, allowing it to flexibly adapt to various usage environments, such as differences in water supply pressure between different floors, or use with water storage containers of different sizes, greatly enhancing the product's versatility and user experience.

[0114] In one possible implementation, the valve port controlling the water inlet 21 is located on the water storage tank 20, or on the water inlet pipe 211, or on the valve port at 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 via a clean water pipe.

[0116] With its 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. Unlike traditional designs, the base station 100 does not need to be permanently connected to a tap. This frees up the placement of the base station 100, allowing users to place it anywhere with a power outlet without having to consider whether there is a water source nearby, greatly increasing the flexibility of home layout.

[0117] In one possible implementation, the water pump 60's inlet can be directly connected to the water inlet faucet via a clean water pipe, or the water tank 20's inlet 21 can be directly connected to the water inlet faucet via a clean 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 communicates with the water storage chamber 241 and is used to discharge gas from the water storage chamber 241. The water storage tank 20 is provided with a sealing element. The sealing element is used to seal the exhaust port 26.

[0119] In the initial state, the sealing element blocks the exhaust port 26, making the water tank 20 a sealed container. When gas is introduced through the air inlet 22, the air pressure quickly builds up within the tank 24 due to the sealed exhaust port 26. This allows for immediate and efficient mixing of liquid and gas, forming a gas-liquid mixture which is then forcibly discharged from the outlet 23. This ensures a rapid response and delay-free start-up of the cleaning function, achieving 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, achieving precise control that stops immediately.

[0120] The vent 26 and the sealing element constitute a simple, resettable pressure protection mechanism. If the control system malfunctions, such as the air inlet 22 continuously intakes air and the water outlet 23 becomes blocked, causing the internal pressure of the water tank 20 to rise abnormally, the vent 26 can be opened under the set pressure or actively opened by the control system to release pressure in time. This effectively prevents the water 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 via the overflow pipe 261.

[0122] When the sealing components fail to seal properly due to aging, wear, or manufacturing tolerances, water and gas can leak into the equipment, easily leading to short circuits, corrosion of metal parts, or bacterial growth. The overflow pipe 261 provides a drainage channel for leaks in the water tank 20, actively guiding leaked water and gas into the cleaning tank 32, preventing water accumulation inside the delicate and dry equipment and protecting core components. Simultaneously, the overflow pipe 261 makes latent faults visible, guiding users to perform timely maintenance. Users will observe unexplained water accumulation in the cleaning tank 32 during non-cleaning periods, providing a clear fault indication signal that the sealing components may have failed and require inspection or replacement. This allows users to take action before the problem worsens, avoiding more costly repairs. Furthermore, the design of the overflow pipe 261 significantly enhances the product's tolerance to manufacturing tolerances and wear, thereby improving overall reliability and service life.

[0123] In one possible implementation, the sealing element includes a floating element 27. The floating element 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 process. When the water level rises to full, the floating component 27 automatically rises under the action of buoyancy and seals the vent 26; when the water level drops, the floating component 27 automatically falls due to the decrease in buoyancy, opening the vent 26. The entire process is completely autonomous, requiring no intervention from any electronic components such as sensors, controllers, or solenoid valves, achieving unpowered automation, simplifying the system architecture, and reducing costs and energy consumption. Furthermore, compared to electronic control schemes that rely on circuits, sensors, and software programs, the purely mechanical float structure virtually eliminates the risk of electronic failures, program errors, or signal interference, resulting in extremely stable operation. Moreover, the floating component 27 has a simple structure, is not easily damaged, and has an extremely long service life, thus 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 element 27 can be connected to a visible indicator rod, or the cover 25 itself can be made of transparent or semi-transparent material. Users can intuitively judge the approximate water level in the water tank 20 by observing the position of the floating element 27, without the need for an additional electronic water level display, thus achieving both functionality and ease of use.

[0126] Please also refer to Figure 6 and Figure 8 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. A floating member 27 is movably connected to the limiting member 251.

[0127] By placing the exhaust port 26 and the limiting member 251 on the cover 25, the exhaust channel, floating sealing mechanism and 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 component 251 provides a precise vertical movement trajectory for the floating component 27 to float up and down, effectively preventing the floating component 27 from tilting, jamming or deviating during the floating or falling process, ensuring that the floating component 27 can accurately and correctly block the exhaust port 26 when it floats up, thus improving the sealing reliability.

[0129] If the sealing mechanism of the floating component 27 malfunctions, the entire cover 25 can be replaced directly, enabling rapid repair and reducing maintenance time and costs. Furthermore, the design of the cover 25, such as the structure of the limiting component 251 and the size of the vent 26, can be optimized and adjusted according to the performance requirements of the water tank 20 or the cleaning tray 30 without altering the structure of the housing 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 blocking part 272 is connected to the floating part 271 and faces the exhaust port 26.

[0132] By configuring the floating component 27 as both a floating part 271 and a sealing part 272, each part can be optimally designed in its function, avoiding the limitations of a single component 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, responding quickly even to small changes in water level. The core function of the sealing part 272 is to achieve a seal, so it can be made of soft, elastic material and designed with a structure that perfectly matches the shape of the vent 26 to ensure a reliable sealing effect.

[0133] Meanwhile, 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, ultimately transmitting the signal 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. Furthermore, the limiting groove 252 effectively prevents the floating part 27 from rolling, translating, or rotating in complex water flow or bubble environments, ensuring a stable movement trajectory for the floating part 27, thereby guaranteeing 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 configuring sensors and motors, precise and programmable control of water level and venting timing can be achieved. Sensors, such as photoelectric and capacitive sensors, can accurately and continuously monitor the water level, unlike the floating component 27 which only triggers at a fixed water level. This allows the control system to acquire richer water level information. Based on this, the closing timing of the vent 26 can be freely set through programming. For example, it can be set to close the vent 26 in advance to begin pre-pressurization when the water volume reaches 90%, thereby achieving a faster system response speed and optimizing the timing control of the entire cleaning process.

[0137] Meanwhile, the electronic control scheme allows for the separation of sensing, control, and execution. Sensors can be installed in locations most conducive to accurate water level measurement, and the exhaust motor can be installed in locations most conducive to sealing or spatial layout, such as the outside of the cover 25, unlike the floating component 27 where all three must be mechanically linked and concentrated at a single point. This liberates the internal structural design of the water tank 20, 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 a leak or blockage in the system by analyzing whether water level changes match 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, which can more reliably overcome resistance and complete the opening and closing action, and has higher long-term reliability in complex water quality environments.

[0139] In one possible implementation, the sealing element may also be a solenoid valve directly disposed 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. The cover 25 has a sealing edge 253 on the side 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 against the box 24, the sealing edge 253 squeezes the sealing element 243 from one side. Simultaneously, the side and bottom walls of the sealing groove 242 also cooperate to compress the sealing element 243, thus 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 within the labyrinthine sealing groove 242, making further leakage difficult. This achieves a multiple sealing effect, greatly improving the reliability of the seal. At the same time, the sealing groove 242 acts as a precise positioning base, ensuring that the sealing element 243, such as an O-ring, is accurately placed in its designed position during assembly, preventing displacement, twisting, or detachment during installation, thus ensuring consistent assembly quality. The sealing groove 242 also protects the sealing element 243, preventing accidental scratches, cuts, or wear during handling, installation, or use, thereby extending the service life of the sealing element 243.

[0142] Since the primary sealing function is provided 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 product yield. Furthermore, the sealing groove 242 and sealing edge 253 surrounding the opening of the water storage cavity 241 effectively form a reinforcing rib on both the housing 24 and the cover 25. When the water tank 20 is pressurized, this structure can better resist deformation caused by pressure, preventing damage to the seal due to "bulging" in the central area of ​​the cover, and ensuring the integrity of the seal under working pressure.

[0143] In one possible implementation, the water storage tank 20 further includes an extension pipe 28. The extension pipe 28 is disposed in the water storage cavity 241. One end of the extension pipe 28 is connected to the water outlet 23, and the other end is disposed 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 chamber 241, allowing almost complete utilization of the liquid in the water storage tank 20. Even with a low water level, the system can continue to draw liquid as long as the inlet of the extension pipe 28 is submerged. Simultaneously, when gas is introduced into the air inlet 22 for pressurization, a bubble-rich gas-liquid mixing zone is formed in the upper part of the water storage chamber 241. The extension pipe 28 draws from the bottom, prioritizing the lower layer of mixed fluid with higher liquid content and density. This ensures the output fluid has sufficient liquid mass and impact force, avoiding the problems of excessive air and insufficient water, weak output, or instability that might occur with direct top-level drawing, thus guaranteeing the stability and effectiveness of the flushing effect.

[0145] The base station 100 provided in this embodiment is applied in 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 mixture within the water storage tank 20. The water outlet 23 is used to output the gas-liquid mixture. The cleaning tray 30 is provided with a spray nozzle 31. The spray nozzle 31 is connected to the water outlet 23 of the water storage tank 20 through a water outlet pipe 231, and is used to inject the gas-liquid mixture into the cleaning tray 30 to rinse the cleaning tray 30.

[0146] By incorporating a water inlet 21 and an air inlet 22 into the water tank 20, a gas-liquid mixture is formed within the tank. This mixture is then automatically flushed through the water outlet 23, water outlet pipe 231, and spray nozzle 31. The gas-liquid mixture, containing numerous air bubbles, generates a stronger local impact and turbulence effect upon impacting the surface of the cleaning tray 30. This effectively removes stubborn stains adhering to the crevices and grooves of the cleaning tray 30, achieving a deeper and more thorough cleaning. This prevents long-term accumulation of dirt, significantly reducing bacterial growth and odor issues, and ensuring a hygienic and healthy home environment. Furthermore, by using a high-pressure gas-liquid mixture to impact and remove waste from designated areas, the cleaning tray 30 is ensured to return to a clean state after each cleaning cycle, preventing cross-contamination and avoiding secondary pollution of the main unit's roller brush due to an unclean cleaning tray 30. Meanwhile, this process is completed automatically by the base station 100 without the need for manual handling by the user, fundamentally solving the problem that users are unwilling to clean due to the tedious cleaning process, and improving the user experience and sense of well-being.

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

[0148] Liquid is supplied 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 the water storage tank 20 is full. At this time, the sealing component seals the vent 26 of the water storage tank 20, forming a closed space.

[0150] Liquid and gas are supplied to the water storage tank 20 simultaneously to pressurize the water storage tank 20 and form a gas-liquid mixture inside 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 sewage, 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 pan 30 through the spray nozzle 31 to rinse the cleaning pan 30.

[0153] Specifically, by activating the valve located 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, thereby rinsing 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 inside 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 and shock waves, generating a strong local shear force. This force is superimposed on the impact force of the water flow itself, which can more effectively peel off and crush stubborn stains. Its cleaning ability far exceeds that of pure water rinsing with the same flow rate and pressure.

[0155] Meanwhile, because gas-liquid mixed fluids have higher cleaning efficiency, the amount of water required to achieve the same level of cleanliness can be significantly reduced, achieving better cleaning results with lower water consumption, thus saving energy and protecting the environment. This process is completely 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 cumbersome 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, so that the sewage is concentrated 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 nozzle 312 to rinse the areas on both 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 plate 30 to rinse the middle area of ​​the cleaning plate 30.

[0160] Specifically, the valve is opened to allow the gas-liquid mixture to be sprayed out through the first nozzle 311 to flush the central area of ​​the cleaning tank 32 and flush the sewage to the sewage outlet 321.

[0161] The sewage collected in the middle of the cleaning pan 30 is extracted by the sewage pump 40.

[0162] Specifically, the sewage pump 40 pumps the sewage from the sewage outlet 321 into the sewage tank 50.

[0163] Through the second nozzles 312 positioned on both sides of the cleaning pan 30 with opposite water outlet directions, a gas-liquid mixture is sprayed from both sides, forming a clean water flow covering the sidewalls and edges of the cleaning pan 30. This effectively washes away dirt adhering to the sidewalls and uses the kinetic energy of the fluid counter-current to drive the dirt from both sides towards the center of the cleaning pan 30. Simultaneously, the first nozzle 311 located in the center is responsible for concentrated rinsing of the central area of ​​the cleaning pan 30, ensuring that every area from the edge to the center is rinsed, eliminating cleaning dead zones. The first nozzle 311 further agitates and suspends the dirt gathered there. The inlet of the wastewater pump 40 is directly connected to the center of the cleaning pan 30, allowing the wastewater and dirt concentrated in the center to be pumped away by the wastewater pump 40 immediately and efficiently. This greatly reduces the residence time of wastewater in the cleaning pan 30, preventing the wastewater from redepositing or contaminating the cleaned surface due to failure to be discharged in time, thus 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 mixture.

[0165] In one possible implementation, the base station cleaning method is intermittent cleaning, which cleans the cleaning tray 30 by rinsing it in stages with a gas-liquid mixture.

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

[0167] After rinsing the cleaning plate 30 for a predetermined time, the sealing device is activated to vent the water storage tank 20.

[0168] Specifically, the scheduled time can be set by the factory or through the program of base station 100.

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

[0170] Intermittent rinsing improves cleaning efficiency. After the first rinse, the upper part of the water tank 20 is filled with compressed gas. If liquid is injected directly, this gas will be violently compressed, creating extremely high pressure that may exceed the system's safety limits or cause difficulties in water injection. Activating the sealing device to release the gas essentially restores the water tank 20 to normal pressure, creating a standard and controllable initial condition for the next water injection. This ensures that each injection reaches the same liquid level and pressure, guaranteeing consistent and reliable rinsing intensity and effectiveness. Conversely, without venting, the compressed gas already inside the water tank 20 occupies a significant amount of space, drastically reducing the actual amount of liquid that can be injected. This would shorten the duration of the next rinse, potentially preventing thorough cleaning.

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

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

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

[0174] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0175] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0176] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0177] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0178] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
