Description

Technical Field

[0001] This disclosure relates to the field of cleaning technology, and in particular to a wastewater tank, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment is a type of smart home appliance that can automatically clean surfaces while moving around. Examples include sweeping and floor scrubbing robots. A floor scrubbing robot has a cleaning component and a wastewater tank. As it moves, it sprays water onto the cleaning component, which then sweeps the surface. The wastewater is then temporarily stored in the tank.

[0003] During operation, the motor creates negative pressure inside the wastewater tank, drawing in air and causing wastewater and dirt to be drawn into the tank along with the air. Existing floor cleaning robots have poor water-air separation in their wastewater tanks, which may result in wastewater being drawn into the motor along with the air, affecting the motor's performance and lifespan. Utility Model Content

[0004] This disclosure provides a wastewater tank, cleaning equipment, and cleaning system to improve the water-air separation effect of the wastewater tank, enabling sufficient water-air separation and thus improving the maintenance-free nature of the system.

[0005] In a first aspect, embodiments of this disclosure provide a wastewater tank for use in cleaning equipment, the wastewater tank comprising:

[0006] The shell has a sludge storage chamber. The shell is provided with a sludge inlet and an air outlet. The sludge inlet and the air outlet are respectively connected to the sludge storage chamber. The sludge inlet is used to draw in water-containing gas, and the air outlet is used to discharge the gas after water-gas separation.

[0007] A water-blocking component is installed inside the sludge storage chamber. The water-blocking component works with the sludge storage chamber to guide the flow path of the water-containing airflow. On the flow path, the liquid in the water-containing airflow sinks to the bottom of the sludge storage chamber, thereby achieving water-air separation of the water-containing airflow.

[0008] The guide structure is located in the sludge storage chamber. The guide structure has a slope, which is used to guide the water-containing airflow entering the sludge storage chamber from the sludge inlet and prevent the water-containing airflow from flowing to the bottom of the sludge storage chamber.

[0009] The wastewater tank disclosed herein features an inlet on its shell for drawing in a mixture of water and gas. An internal storage chamber holds and processes wastewater drawn from cleaning equipment. An outlet discharges the separated gas. A water-blocking component located within the storage chamber, along with the chamber's inner wall, guides the flow path of the water-containing gas stream. This path restricts the flow of the water-containing gas stream, intercepting the water vapor during separation. The liquid portion settles to the bottom of the storage chamber, while the gas continues to flow and is discharged through the outlet, achieving gas-liquid separation of the water-containing gas stream. Simultaneously, a guide structure is designed near the inlet. The slope of this guide structure guides the incoming water-containing gas stream, preventing it from flowing to the bottom of the storage chamber. This eliminates initial ripples on the wastewater surface and prevents the gas from blowing onto the liquid surface at the bottom of the storage chamber, thus improving the water-gas separation effect. Through these designs, the wastewater tank can significantly improve the water-air separation effect, ensuring that the gas drawn into the motor is free of liquid. This not only reduces the potential impact of liquid on motor performance and lifespan, but also enhances the maintenance-free characteristics of the equipment. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] Cleaning equipment is a type of smart home appliance that can automatically clean surfaces while moving around. Examples include sweeping and floor scrubbing robots. A floor scrubbing robot has a cleaning component and a wastewater tank. As it moves, it sprays water onto the cleaning component, which then sweeps the surface. The wastewater is then temporarily stored in the tank.

[0021] During operation, the motor creates negative pressure inside the wastewater tank, drawing in air. This causes wastewater and dirt to be drawn into the wastewater tank along with the air. Existing floor cleaning robots have poor water-air separation in their wastewater tanks, which may result in wastewater being drawn into the motor along with the air, affecting the motor's performance and lifespan.

[0022] To overcome the shortcomings of related technologies, after repeated consideration and verification, the inventors discovered that by incorporating a water-air separation structure inside the sewage tank: a water-blocking structure isolates the water-containing airflow, achieving water-air separation; a slope structure guides the airflow, preventing it from hitting the liquid surface and causing water flow oscillations; and finally, a filter screen intercepts solid waste at the rear, providing anti-surge and water-air separation effects. Specifically, the water-blocking ribs intercept water and air during the separation process; the slope structure at the suction inlet eliminates initial airflow surges on the sewage tank surface; and the filter screen separates water and air at the rear. This significantly improves the water-air separation effect, ensuring that the gas drawn into the motor is free of liquid.

[0023] In view of this, the present disclosure provides a wastewater tank for use in cleaning equipment, the wastewater tank comprising:

[0024] The shell has a sludge storage chamber. The shell is provided with a sludge inlet and an air outlet. The sludge inlet and the air outlet are respectively connected to the sludge storage chamber. The sludge inlet is used to draw in water-containing gas, and the air outlet is used to discharge the gas after water-gas separation.

[0025] A water-blocking component is installed inside the sludge storage chamber. The water-blocking component works with the sludge storage chamber to guide the flow path of the water-containing airflow. On the flow path, the liquid in the water-containing airflow sinks to the bottom of the sludge storage chamber, thereby achieving water-air separation of the water-containing airflow.

[0026] The guide structure is located in the sludge storage chamber. The guide structure has a slope, which is used to guide the water-containing airflow entering the sludge storage chamber from the sludge inlet and prevent the water-containing airflow from flowing to the bottom of the sludge storage chamber.

[0027] By designing an inlet on the casing to draw in a mixture of water and gas, and a storage chamber inside the casing to hold and treat wastewater drawn in from the cleaning equipment, an outlet is designed to discharge the separated gas. A water-blocking component located inside the storage chamber forms a flow path with the inner wall of the chamber. This path restricts the flow of water-containing gas, intercepting water and gas during the separation process. The liquid portion settles to the bottom of the storage chamber, while the gas portion continues to flow and is finally discharged through the outlet, achieving gas-liquid separation of the water-containing gas stream. Simultaneously, a guide structure is designed near the inlet. The slope of the guide structure guides the incoming water-containing gas stream, preventing it from flowing to the bottom of the storage chamber. This eliminates the initial surge of airflow on the liquid surface of the wastewater tank and prevents airflow from blowing onto the liquid surface at the bottom of the storage chamber, thus improving the water-gas separation effect. Through these designs, the wastewater tank can significantly improve the water-gas separation effect, ensuring that the gas drawn into the motor is free of liquid. This not only reduces the potential impact of liquid on motor performance and lifespan but also enhances the maintenance-free characteristics of the equipment.

[0028] The contents of this disclosure 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 disclosure.

[0029] The following sections provide a detailed description of the specific structure of the wastewater tank and various possible implementation methods.

[0030] Figure 1 This is a schematic diagram of the structure of a sewage tank provided in an embodiment of this disclosure. Figure 2 for Figure 1 One of the partial exploded structural diagrams of the sewage tank shown. Figure 3 for Figure 1 The second part of the exploded structure diagram of the sewage tank is shown. Figure 4 for Figure 1 The third schematic diagram showing the partial disassembled structure of the sewage tank. Figure 5 for Figure 1 The diagram shows the flow path of the sewage tank during operation. Figure 6 for Figure 1 The diagram shows the simulation results of water-air separation in the wastewater tank.

[0031] like Figure 1 and Figure 2 As shown in the embodiment of this disclosure, the wastewater tank 100 is used in cleaning equipment. The wastewater tank 100 is used to temporarily store the wastewater generated during the operation of the cleaning equipment.

[0032] 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.

[0033] In one possible implementation, the cleaning device can be a floor cleaning robot. However, it is not limited to this; in other possible implementations, the cleaning device can also be a sweeping and mopping robot, or other self-moving cleaning devices that meet cleaning needs.

[0034] like Figure 3 and Figure 4 As shown, the wastewater tank 100 includes a shell 10, a water-blocking component 20, and a guiding structure 30. The water-blocking component 20 and the guiding structure 30 are respectively disposed in the shell 10. A wastewater storage chamber 11 is formed in the shell 10. The shell 10 is provided with a wastewater inlet 12 and an air outlet 13. The wastewater inlet 12 and the air outlet 13 are respectively connected to the wastewater storage chamber 11. The wastewater inlet 12 is used to draw in water-containing gas, and the air outlet 13 is used to discharge the gas after water-gas separation.

[0035] In one possible implementation, the air outlet 13 is connected to the air duct system of the cleaning equipment. Specifically, the air outlet 13 can be connected to the main fan through a HEAP filter to generate suction and draw out the airflow from the sludge storage chamber 11.

[0036] like Figure 5 As shown, the water-blocking component 20 is disposed inside the sludge storage chamber 11. The water-blocking component 20 cooperates with the inner wall of the sludge storage chamber 11 to guide the flow path 21 of the water-containing airflow. On the flow path 21, the liquid in the water-containing airflow sinks to the bottom of the sludge storage chamber 11, thereby realizing the separation of water and air in the water-containing airflow.

[0037] The guide structure 30 is disposed in the sludge storage chamber 11 and is located near the sludge inlet 12. The guide structure 30 has a slope 31, which is used to guide the water-containing airflow entering the sludge storage chamber 11 from the sludge inlet 12 and prevent the water-containing airflow from flowing to the bottom of the sludge storage chamber 11.

[0038] A wastewater inlet 12 is designed on the housing 10 to draw in a mixture of water and gas. A wastewater storage chamber 11 is provided inside the housing 10 to hold and treat wastewater drawn in from the cleaning equipment. An exhaust port 13 is designed to discharge the separated gas. A water-blocking component 20 is designed inside the wastewater storage chamber 11, forming a flow path 21 together with the inner wall of the chamber. This path restricts the flow of the water-containing gas, intercepting the water vapor during the separation process, causing the liquid portion to settle to the bottom of the wastewater storage chamber 11, while the gas portion continues to flow and is finally discharged through the exhaust port 13, thus achieving gas-liquid separation of the water-containing gas stream. Simultaneously, a guide structure 30 is designed near the wastewater inlet 12. The slope 31 of the guide structure 30 guides the incoming water-containing gas stream, preventing it from flowing to the bottom of the wastewater storage chamber 11, eliminating the initial surge of airflow on the liquid surface of the wastewater tank 100, and preventing airflow from blowing onto the liquid surface at the bottom of the wastewater storage chamber 11, causing liquid surface oscillation, thereby helping to improve the water-gas separation effect. Through these designs, the wastewater tank 100 can significantly improve the water-air separation effect, ensuring that the gas drawn into the motor is free of liquid. This not only reduces the potential impact of liquid on motor performance and lifespan, but also enhances the maintenance-free characteristics of the equipment.

[0039] In one possible implementation, the housing 10 includes a main body 14 and a cover 15. The main body 14 has a sludge storage cavity 11, and the cover 15 is placed on the main body 14 to seal the sludge storage cavity 11. A guide structure 30 is disposed in the sludge storage cavity 11.

[0040] The design of the main body 14 and the cover 15 allows for easy disassembly and assembly of the wastewater tank 100. Users can easily open the cover 15 to clean and maintain the wastewater storage chamber 11, thus maintaining the hygiene and functionality of the equipment. The tight fit between the cover 15 and the main body 14 effectively prevents wastewater and gas leakage, ensuring efficient water-gas separation and preventing external contaminants from entering the wastewater storage chamber 11. The modular design (main body 14 and cover 15) allows for greater flexibility in design and manufacturing. Different materials and manufacturing processes can be applied to the main body 14 and the cover 15 to meet specific performance requirements or cost considerations. Simultaneously, the modular design simplifies the manufacturing process and reduces production costs. During transportation and storage, the modular components can utilize space more effectively, reducing logistics costs.

[0041] In one possible implementation, the water-blocking component 20 is disposed on the cover 15 and is positioned toward the sewage inlet 12, that is, the water-blocking component 20 is positioned close to the sewage inlet 12.

[0042] The water-blocking component 20, positioned near the inlet 12, can initiate the separation process immediately upon the entry of the water-containing airflow into the storage chamber 11, thus improving the overall water-air separation efficiency. By placing the water-blocking component 20 near the inlet 12, liquid can be effectively prevented from entering the outlet 13 with the airflow, reducing the risk of liquid entering the airflow channel and protecting downstream equipment, such as motors, from liquid damage, thereby extending the equipment's service life. Simultaneously, integrating the water-blocking component 20 into the cover 15 simplifies the overall design and installation process of the sewage tank 100, reducing the number and complexity of components, thereby lowering manufacturing and maintenance costs. Since the water-blocking component 20 is integrated with the cover 15, users only need to handle the main body 14 during cleaning and maintenance, making the cleaning process more convenient and faster. Furthermore, the water-blocking component 20, positioned on the cover 15, utilizes the structural strength of the cover 15 to better resist fluid impact and vibration, improving the stability of the entire system. By placing the water-blocking component 20 on the cover 15, the internal space of the storage chamber 11 can be utilized more effectively, helping to maintain the compactness of the sewage tank 100 without compromising its functionality. Since the water-blocking component 20 is integrated with the cover 15, its shape and position can be adjusted more flexibly to adapt to different fluid dynamics requirements and equipment specifications.

[0043] In one possible implementation, the water-blocking component 20 can also be positioned in the airflow path to isolate the gas and liquid during the airflow process.

[0044] In one possible implementation, the inlet 12 and the outlet 13 are both located on the main body 14 and on different walls of the sludge storage chamber 11.

[0045] By placing the inlet 12 and outlet 13 on different walls, the airflow path can be effectively controlled, reducing turbulence and flow. The airflow can then flow orderly within the storage chamber 11, improving the efficiency of water-gas separation. Simultaneously, this layout maximizes the path length for gas-liquid separation, allowing the liquid more opportunities to settle to the bottom of the storage chamber 11, while the gas is discharged through the outlet 13, ensuring more thorough water-gas separation. Furthermore, separating the inlet 12 and outlet 13 effectively prevents the separated gas from remixing with the liquid, reducing the risk of cross-contamination. Placing the inlet 12 and outlet 13 on different walls also allows for more flexible arrangement of pipes and connections, facilitating installation and maintenance, and reducing pipe crossings and interference. Through a rational layout of the inlet 12 and outlet 13, the internal space of the storage chamber 11 can be utilized more effectively, maintaining the compactness of the equipment without compromising its functionality.

[0046] In one possible implementation, a sealing structure 16 is provided between the main body 14 and the cover 15, and the sealing structure 16 is used to seal the sludge storage cavity 11.

[0047] The sealing structure 16 effectively prevents sewage and gas from leaking from the sludge storage chamber 11, helping to maintain a clean and safe environment around the equipment. Furthermore, by ensuring the airtightness of the sludge storage chamber 11, external air is prevented from entering, maintaining internal pressure balance and thus improving the efficiency of water-gas separation. The sealing structure 16 also prevents external contaminants, such as dust and particles, from entering the sludge storage chamber 11, protecting internal components from damage and extending the equipment's service life. Good sealing reduces the transmission of airflow and vibration through gaps, helping to reduce noise during equipment operation.

[0048] In one possible implementation, the wastewater tank 100 further includes a filter structure 40 disposed in the wastewater storage chamber 11 and used for filtration at the air outlet 13.

[0049] The filter structure 40 effectively removes tiny particles and impurities from the airflow, ensuring that the gas discharged from the outlet 13 is purer and protecting downstream equipment, such as motors, from particulate damage. Simultaneously, as a supplementary layer for water-air separation, the filter structure 40 further captures and separates residual droplets and fine particles from the airflow, thereby improving the overall water-air separation efficiency.

[0050] In one possible implementation, the filter structure 40 is disposed on the cover 15, and the filter structure 40 is provided with a filter outlet 41 communicating with the air outlet 13 on the side facing the air outlet 13. The filter structure 40 is also provided with a plurality of filter holes 42 communicating with the sludge storage chamber 11.

[0051] This design ensures that the airflow is effectively filtered as it passes through the filter structure 40. Gas enters the filter structure 40 from the sludge storage chamber 11 through multiple filter holes 42 and then exits through the filter outlet 41, optimizing the filtration process and improving filtration efficiency. By providing filter holes 42 on multiple surfaces of the filter structure 40, the contact area between the gas and the filter medium is increased, thereby improving filtration efficiency and ensuring more thorough removal of particles and impurities from the airflow. Integrating the filter structure 40 onto the cover 15 reduces the number of individual components, simplifies the overall structural design, and helps reduce manufacturing and assembly complexity.

[0052] like Figure 6The diagram shows a simulation of water-air separation during the operation of the sewage tank. The depth of the lines represents the speed of the gas-liquid flow. The high-speed water-containing airflow drawn in from the inlet 12 is guided by the water-blocking component 20 in the sewage storage chamber 11, causing it to flow in a spiral around the chamber and undergo water-air separation. The water-blocking component 20 intercepts the water-air during the separation process, thus achieving water-air separation. The slope 31 structure at the inlet 12 is used to eliminate the surge of airflow on the liquid surface of the sewage tank 100 in the initial stage. The airflow reaching the middle of the sewage storage chamber 11 along the flow path is slowed down due to the obstruction and guidance during the flow. The suction device such as the motor at the rear of the outlet 13 generates suction, which accelerates the low-speed airflow in the middle of the sewage storage chamber 11 through the filter structure 40 and is discharged from the outlet 13. The filter structure 40 is used to intercept solid waste at the rear and plays a certain role in preventing surges and separating water-air, thus achieving a good water-air separation effect. After the gas and liquid enter the sewage tank 100, they are guided by the water-blocking component 20, the slope 31, and the filter structure 40, causing the gas and liquid to flow in a certain direction. Figure 5 The liquid moves in the direction of the middle arrow, with the heavier liquid sinking into the sewage tank 100 and the lighter gas rising and being discharged from the gas outlet 13, thus achieving water-gas separation.

[0053] In one possible implementation, the wastewater tank 100 is also connected to the sludge extraction system of the cleaning equipment. The sludge extraction system can extract wastewater and other pollutants from the sludge storage chamber 11, thereby improving the maintenance-free nature of the system.

[0054] In one possible implementation, the housing 10 is provided with a sludge extraction port 17, which is connected to the sludge storage chamber 11, and the sewage tank 100 is provided with a flip-top structure 18, which is used to open or block the sludge extraction port 17.

[0055] The inclusion of a sludge suction port 17 makes discharging wastewater from the sludge storage chamber 11 more convenient and faster. Users can easily open the sludge suction port 17 through the flip-top structure 18 to drain the wastewater without disassembling the entire wastewater tank 100. By providing a dedicated sludge suction port 17, regular cleaning and maintenance can be performed more efficiently, reducing equipment downtime and maintenance costs.

[0056] The flip-top structure 18 effectively seals the sludge suction port 17, preventing accidental leakage of sewage when the equipment is moved or tilted, thereby reducing the risk of spillage and keeping the equipment and surrounding environment clean. The flip-top structure 18 is designed for ease of operation, allowing users to easily open or close the sludge suction port 17, improving the convenience of use and user satisfaction. The flip-top structure 18 can be designed with different opening methods, such as rotation or sliding, to adapt to different usage scenarios and space constraints.

[0057] In one possible implementation, the sludge extraction port 17 is provided on the cover 15, and the sludge extraction port 17 is used for the insertion of the sludge extraction pipe 201 of the sludge extraction device.

[0058] In one possible implementation, the sewage suction device is a base station, and the sewage suction pipe 201 is located in the base station, which can be moved, inserted, and removed via the base station's drive mechanism. In other possible implementations, the sewage suction device is a separately installed sewage discharge structure, and the sewage suction pipe 201 is directly connected to the sewer outlet.

[0059] The sludge suction port 17 is located on the cover 15, making it easier to connect the sludge suction pipe 201. Users can directly insert the pipe through the sludge suction port 17 on the cover 15 to discharge sewage without disassembling the entire sewage tank 100. Because the sludge suction port 17 is located on the cover 15, users can perform sewage discharge operations without opening the entire device. This simplifies the operation process, reduces equipment downtime, facilitates regular cleaning and maintenance, and improves equipment maintenance efficiency. By providing the sludge suction port 17 on the cover 15, the flow path of sewage can be better controlled, reducing the risk of leakage during sewage discharge.

[0060] Fixing the sludge suction pipe 201 in the sewage tank 100 would occupy the internal space of the sewage tank 100, thereby reducing the effective volume of the sewage tank 100. By setting the sludge suction port 17 on the sewage tank 100 and placing the sludge suction pipe 201 on the outside, it can be inserted from the outside when needed. This can maximize the utilization of the internal space of the sewage tank 100. At the same time, the design of the externally inserted sludge suction pipe 201 also provides greater flexibility. The length or insertion length and position of the sludge suction pipe 201 can be adjusted as needed to adapt to different operational requirements, different sewage tanks 100 or changes in the liquid level of the sewage tank 100.

[0061] Furthermore, the absence of a sludge suction pipe 201 in the sewage tank 100 makes the interior of the sewage tank 100 easier to clean and maintain, reducing obstacles during cleaning. Conversely, fixing a sludge suction pipe 201 in the sewage tank 100 can easily lead to the accumulation of dirt and sediment, increasing the risk of blockage.

[0062] In one possible implementation, a sealing ring 171 is provided at the sewage inlet 17, which is used to cooperate with the flip cover structure 18 to seal the sewage inlet 17.

[0063] The sealing ring 171 provides an effective sealing interface, preventing sewage and gas from leaking through the sludge suction port 17, thus maintaining a clean and safe environment around the equipment. The cooperation between the sealing ring 171 and the flip-top structure 18 ensures that the sludge suction port 17 remains completely sealed when not in use, thereby improving the overall sealing performance of the equipment. Effectively sealing the sludge suction port 17 prevents odors from the sewage from spreading into the surrounding environment, improving the air quality of the operating environment.

[0064] In one possible implementation, the wastewater tank 100 is also connected to the cleaning system of the cleaning equipment. The cleaning system can clean the wastewater tank 100, thereby improving the maintenance-free nature of the system. The sludge storage chamber 11 in the wastewater tank 100 is where dirt accumulates, so the cleaning system mainly targets the sludge storage chamber 11 to clean it and remove the dirt.

[0065] In one possible implementation, the sewage tank 100 is further provided with a cleaning device 50, which is used to inject water into the sewage storage chamber 11 to clean the sewage storage chamber 11.

[0066] The cleaning device 50 can automatically or manually inject water into the sludge storage chamber 11, quickly removing residual dirt and deposits, improving cleaning efficiency, and reducing the time and labor intensity of manual cleaning. Regular cleaning of the sludge storage chamber 11 helps prevent the growth of bacteria and odors, maintaining a hygienic environment inside the equipment and improving overall air quality. Regular cleaning reduces corrosion and wear on the sludge storage chamber 11 and related components, thereby extending the equipment's lifespan. The automated cleaning process reduces the frequency of equipment maintenance, lowers maintenance costs and downtime, and improves equipment availability. Users can easily start the cleaning device 50 without disassembling the equipment, enhancing operational convenience and user experience. Regular cleaning also helps prevent clogging of pipes and the filter structure 40, ensuring normal operation and high efficiency of the equipment.

[0067] In one possible implementation, the cleaning device 50 is a spraying device, including a plurality of nozzles 51 disposed on the surface of the guide structure 30.

[0068] The arrangement of multiple nozzles 51 ensures that the cleaning fluid covers every corner and surface of the dirt storage chamber 11, especially the complex guide structure 30 area, thereby achieving a comprehensive and thorough cleaning effect. The multi-point distribution of nozzles 51 allows simultaneous action on multiple areas, shortening cleaning time, improving cleaning efficiency, and reducing equipment downtime. The nozzles 51 can be designed with different spray angles and pressures to more effectively remove dirt and deposits, especially in areas of the guide structure 30 where dirt easily accumulates. Optimizing the design and layout of the nozzles 51 enables efficient water resource utilization, reducing water waste during cleaning and meeting environmental protection requirements. The number, position, and spray pattern of the nozzles 51 can be adjusted according to specific needs to adapt to different equipment designs and cleaning requirements.

[0069] In one possible implementation, the cleaning device 50 may also be a nozzle 51 or a liquid injection pipe or other structure separately disposed in the sludge storage chamber 11.

[0070] In one possible implementation, the cleaning device 50 can be a single / group of non-rotatable perforated water distributor structures or a single / group of rotatable nozzles 51, thereby ensuring coverage of the interior of the wastewater tank 100.

[0071] In one possible implementation, to increase the spray pressure of nozzle 51, a high-pressure nozzle 51 or an air pump can be introduced.

[0072] In one possible implementation, the wastewater tank 100 also includes a piping structure 60, which is connected to the cleaning device 50.

[0073] The piping structure 60 enables the cleaning device 50 to automatically acquire water, supporting an automated cleaning process, reducing the need for manual operation, and improving cleaning efficiency. The piping structure 60 ensures a stable water supply to the cleaning device 50, guaranteeing the continuity and effectiveness of the cleaning process and preventing incomplete cleaning due to unstable water flow. By rationally designing the piping structure 60, the water flow path and usage can be optimized, achieving efficient water resource utilization, reducing waste, and meeting environmental protection requirements. The integrated piping structure 60 reduces the complexity of external piping and connections, simplifying the overall design and installation process. The piping structure 60 can be customized to meet specific equipment needs, adapting to different spatial layouts and functional requirements.

[0074] The air pump is connected to the pipeline structure 60, thereby increasing the pressure of the water flow.

[0075] In one possible implementation, a heating device may also be installed on the pipeline structure 60 to heat the water, thereby spraying and cleaning the sludge storage chamber 11 with steam or hot water.

[0076] The heating device heats the cleaning water, and hot water, compared to cold water, has a stronger dissolving and cleaning ability, more effectively removing grease, dirt, and stubborn residues. If the cleaning water contains detergent, hot water accelerates the reaction rate of the chemical detergent, improving cleaning efficiency and shortening cleaning time. Due to the enhanced cleaning power of hot water, the amount of detergent used can be reduced, thereby lowering operating costs and environmental impact. Furthermore, the hot water provided by the heating device has a sterilizing and disinfecting effect, helping to reduce bacterial growth in the wastewater tank and improving hygiene standards. The system can adjust the water temperature as needed to adapt to different cleaning tasks and types of dirt, increasing the system's flexibility and applicability. By increasing the water temperature, the cleaning effect can be improved without increasing the water volume, thus saving water resources.

[0077] In one possible implementation, the clean water tank and the waste water tank in the cleaning equipment are a combined structure, with the waste water tank 100 located inside the clean water tank. However, this is not the only possible implementation. In other possible implementations, the clean water tank and the waste water tank in the cleaning equipment are separate structures, with the waste water tank 100 and the clean water tank connected by a pipeline structure 60.

[0078] In one possible implementation, the sewage tank 100 also includes a tank body 70, with a water storage cavity 71 formed between the tank body 70 and the shell 10, and the pipeline structure 60 connected to the water storage cavity 71.

[0079] The water storage chamber 71 serves as the water storage space for the clean water tank. By placing the shell 10 within the main body 70 of the water tank, the system's integration can be improved. At this time, the cover 15 simultaneously covers both the main body 14 and the main body 70 of the water tank, sealing the sludge storage chamber 11 in the main body 14 and the water storage chamber 71 in the main body 70, respectively.

[0080] The water storage chamber 71 provides an independent water source, enabling the cleaning device 50 to supply water without relying on an external water source, enhancing the equipment's autonomy and flexibility. Through the design of the water storage chamber 71, the cleaning device 50 can quickly obtain the required water volume, ensuring the efficiency and continuity of the cleaning process and reducing waiting time. The water storage chamber 71 can adjust and manage the water volume as needed, ensuring the rational use of water resources and reducing waste during the cleaning process. The design of the water tank body 70 and the water storage chamber 71 can be adjusted according to the specific needs of the equipment to adapt to different space and functional requirements.

[0081] In other possible implementations, the pipeline structure 60 can also be connected to the base station's clean water tank or water supply and drainage pipes.

[0082] In one possible implementation, the wastewater tank 100 also includes a water level detection component 80 for detecting the water level in the wastewater storage chamber 11 and / or the water storage chamber 71.

[0083] The water level detection component 80 can monitor the water level in the sludge storage chamber 11 in real time. When the water level approaches full capacity, it will issue an alarm or automatically stop water intake to prevent sewage overflow and maintain the cleanliness of the equipment and the environment. In the water storage chamber 71, the water level detection component 80 helps ensure sufficient water for the cleaning process while avoiding overfilling, thus conserving water resources. By monitoring the water level, it prevents equipment malfunctions caused by excessively high or low water levels, protecting the normal operation and safety of the equipment. The water level detection component 80 can be integrated with the control system to achieve automated water level management, such as automatically starting or stopping the water pump, simplifying the operation process and improving the intelligence level of the equipment. Automated water level monitoring reduces the need for manual inspection and adjustment, lowering labor intensity and reducing human error.

[0084] In one possible implementation, the water level detection component 80 can detect the presence of the sewage tank 100, the fullness of the sewage storage chamber 11, the water shortage of the water storage chamber 71, and the fullness of the water storage chamber 71.

[0085] In one possible implementation, the cleaning equipment also includes a cleaning component, with the piping structure 60 connected to the cleaning component. The cleaning component is a part of the cleaning equipment used for direct contact and treatment of dirt on the floor or other surfaces, achieving efficient cleaning through a combination of water flow and physical contact. Water in the water storage chamber 71 is supplied to the cleaning component during cleaning operations.

[0086] The control device manages the water supply and timing of the pipeline structure 60, ensuring that the cleaning components receive sufficient water flow at the appropriate time. At the same time, the user can adjust the working mode and water flow parameters of the cleaning components through the control interface to adapt to different cleaning tasks.

[0087] Combined with the automatic water supply function of the piping structure 60, the cleaning components can remain continuously moist during operation, enhancing the ability to dissolve and remove dirt, reducing manual intervention, and improving automation. If the cleaning components are rollers, drums, or rotating mops, they provide strong physical friction, enabling faster removal of stubborn dirt and residue through mechanical action, thus improving cleaning efficiency. The cleaning components can be replaced or adjusted according to different cleaning needs to adapt to different types of dirt and cleaning tasks, increasing the system's versatility. Due to the physical cleaning action of the components, good cleaning results can be achieved with reduced or no detergent, thereby reducing operating costs and environmental impact. The cleaning components can also be designed with specific shapes to clean hard-to-reach areas or complex surface structures, achieving precise cleaning.

[0088] In one possible implementation, the pipeline structure 60 is equipped with a valve that connects the pipeline structure 60 to the cleaning device 50 and the cleaning components. The valve is used to switch the connection between the pipeline structure 60 and the cleaning device 50 or the cleaning components to improve the functional flexibility of the cleaning equipment and the efficiency of water resource utilization.

[0089] The valve can switch between the cleaning device 50 and the cleaning component via instructions from the control device, ensuring that the water flow is correctly guided according to the current cleaning task.

[0090] When returning to the base station for maintenance, the valve opens the cleaning pipeline structure 60 and the cleaning device 50, and closes the pipeline structure 60 and the cleaning component, thereby allowing water to be supplied to the sludge storage chamber 11.

[0091] The valve, located at a branch point of the piping structure 60, connects the cleaning device 50 and the cleaning component. The valve allows for switching the water flow between the cleaning device 50 and the cleaning component, enabling the system to flexibly adjust the water flow direction according to specific cleaning tasks, thus improving cleaning efficiency. By precisely controlling the water flow direction, water resources can be concentrated on specific cleaning components when needed, avoiding unnecessary water waste. The system can select the appropriate cleaning path (cleaning device 50 or cleaning component) according to different cleaning requirements, thereby adapting to various cleaning tasks and environments. Through effective water flow management and resource optimization, the system's operating costs are reduced, including savings in water resources and energy consumption.

[0092] In one possible implementation, the angle between the opening direction of the sewage inlet 12 and the wall of the sewage storage chamber 11 through which the sewage inlet 12 is opened is an acute angle.

[0093] The acute-angle design guides the water-containing airflow more smoothly into the sludge storage chamber 11, reducing flow resistance and turbulence, thereby improving sludge intake efficiency. Through the acute-angle design, the water-containing airflow flows closer to the wall surface when entering the sludge storage chamber 11, reducing the risk of turbulence. Furthermore, the acute-angled sludge inlet 12 helps reduce the accumulation of contaminants at the inlet, lowering the possibility of blockage and ensuring normal equipment operation. Due to the optimized flow path, the acute-angle design can utilize the kinetic energy of the fluid to help remove contaminants adhering to the wall surface, enhancing self-cleaning capabilities. By reducing flow resistance and optimizing the fluid path, the acute-angle design helps improve the overall efficiency of the equipment and reduce energy consumption. The smoother entry of the water-containing airflow into the sludge storage chamber 11 reduces flow noise and improves the equipment's quiet operation.

[0094] In one possible implementation, the opening of the inlet 12 located on the wall of the sludge storage chamber 11 is directed away from the bottom wall of the sludge storage chamber 11.

[0095] By directing the inlet 12 away from the bottom wall, the water-containing airflow can be better dispersed when entering the storage chamber 11, reducing direct impact on the bottom liquid surface. This promotes fluid circulation within the storage chamber 11, allowing the water-containing airflow to flow within the flow path 21, thereby improving the efficiency of gas-liquid separation. The water-containing airflow also enters the storage chamber 11 more gently, reducing flow noise and improving the equipment's quietness.

[0096] In one possible implementation, the sewage tank 100 also includes a handle 90, which is rotatably disposed on the housing 10.

[0097] The rotatable handle 90 design allows users to easily lift and move the sewage tank 100, improving the portability of the equipment. When not in use, the handle 90 can be rotated to a flat position, reducing space occupation and facilitating storage and transportation. Users can adjust the position of the handle 90 as needed to obtain the optimal grip angle and comfort, improving the convenience and comfort of operation.

[0098] The wastewater tank 100 provided in this embodiment includes a shell 10, a water-blocking component 20, and a guiding structure 30. A wastewater storage chamber 11 is formed in the shell 10. The shell 10 is provided with a wastewater inlet 12 and an air outlet 13. The wastewater inlet 12 and the air outlet 13 are respectively connected to the wastewater storage chamber 11. The wastewater inlet 12 is used to draw in water-containing airflow, and the air outlet 13 is used to discharge the gas after water-gas separation of the water-containing airflow. The water-blocking component 20 is disposed in the wastewater storage chamber 11. The water-blocking component 20 cooperates with the wastewater storage chamber 11 to guide the flow path 21 of the water-containing airflow. On the flow path 21, the liquid in the water-containing airflow sinks to the bottom of the wastewater storage chamber 11, realizing water-gas separation of the water-containing airflow. The guiding structure 30 is disposed in the wastewater storage chamber 11. The guiding structure 30 has a slope 31. The slope 31 is used to guide the water-containing airflow entering the wastewater storage chamber 11 from the wastewater inlet 12 and prevent the water-containing airflow from flowing to the bottom of the wastewater storage chamber 11.

[0099] A wastewater inlet 12 is designed on the housing 10 to draw in a mixture of water and gas. A wastewater storage chamber 11 is provided inside the housing 10 to hold and treat wastewater drawn in from the cleaning equipment. An exhaust port 13 is designed to discharge the separated gas. A water-blocking component 20 is designed inside the wastewater storage chamber 11, forming a flow path 21 together with the inner wall of the chamber. This path restricts the flow of the water-containing gas, intercepting the water vapor during the separation process, causing the liquid portion to settle to the bottom of the wastewater storage chamber 11, while the gas portion continues to flow and is finally discharged through the exhaust port 13, thus achieving gas-liquid separation of the water-containing gas stream. Simultaneously, a guide structure 30 is designed near the wastewater inlet 12. The slope 31 of the guide structure 30 guides the incoming water-containing gas stream, preventing it from flowing to the bottom of the wastewater storage chamber 11, eliminating the initial surge of airflow on the liquid surface of the wastewater tank 100, and preventing airflow from blowing onto the liquid surface at the bottom of the wastewater storage chamber 11, causing liquid surface oscillation, thereby helping to improve the water-gas separation effect. Through these designs, the wastewater tank 100 can significantly improve the water-air separation effect, ensuring that the gas drawn into the motor is free of liquid. This not only reduces the potential impact of liquid on motor performance and lifespan, but also enhances the maintenance-free characteristics of the equipment.

[0100] This disclosure also provides a cleaning device, including the aforementioned wastewater tank 100.

[0101] This disclosure also provides a cleaning system, including a base station and the cleaning equipment described above.

[0102] In one possible implementation, the base station includes a drive mechanism and a sewage suction pipe 201. The drive mechanism is used to drive the sewage suction pipe 201 to move so as to extend or withdraw the sewage suction pipe 201 into or out of the sewage suction port 17 of the sewage tank 100.

[0103] The drive mechanism automatically controls the movement of the sewage extraction pipe 201, enabling automatic sewage extraction and treatment, reducing manual operation and improving the system's automation level. The automated sewage extraction process shortens the downtime of the cleaning equipment, allowing it to return to work more quickly and improving cleaning efficiency. Users do not need to manually handle sewage, reducing labor intensity and human error, and improving operational convenience and safety.

[0104] In one possible implementation, the sewage suction pipe 201 is provided with a sealing ring 171, which is used to seal the connection between the sewage suction pipe 201 and the sewage suction port 17 when the sewage suction pipe 201 extends into the sewage suction port 17.

[0105] The sealing structure 16 effectively prevents sewage from leaking from the connection during the pumping process, maintaining the overall hygiene of the cleaning system and the cleanliness of the working environment. By ensuring the tightness of the connection, the system can maintain stable pressure and flow, improving pumping efficiency. The sealing structure 16 reduces the risk of sewage leakage, lowers environmental pollution and health threats to operators, while preventing liquid leakage helps protect other components of the equipment from corrosion and damage, extending the service life of the equipment.

[0106] In one possible implementation, at least one of the sludge suction pipe 201 and the sludge suction port 17 is provided with a sealing ring 171.
