Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a water circuit system for a cleaning machine and a cleaning machine. Background Technology

[0002] Existing cleaning equipment, such as dishwashers and bottle washers, typically only has one water tank, through which water for both the main wash and final wash stages is supplied to the washing chamber. In some scenarios, the final wash stage requires water of higher quality, which a single water tank cannot meet, resulting in poor operational flexibility. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0003] Therefore, it is necessary to provide a water system and cleaning machine to address the lack of flexibility in using a single water tank in cleaning machines.

[0004] A water system for a cleaning machine includes: a housing assembly having a first interface, a second interface, and a cleaning chamber; a first water tank assembly having a first water inlet connected to the first interface; a second water tank assembly having a second water inlet connected to the second interface; and a water inlet assembly disposed on the housing assembly, connected to the cleaning chamber, and connected to both the first and second interfaces, wherein the water inlet assembly can control the connection or disconnection of the first and second interfaces with the cleaning chamber.

[0005] The aforementioned water system of the cleaning machine connects the first and second water tank components to the first and second interfaces of the housing component via the first and second water inlets, respectively. This provides a basic guarantee for water filling and cleaning operations, simplifying the operation process. Simultaneously, the water inlet component can effectively control the on / off state between the first and second interfaces and the cleaning chamber. This function allows the system to use different water qualities in each tank according to the characteristics of different cleaning objects and the specific needs of different cleaning stages. The final cleaning stage uses higher-quality water for a cleaner and healthier result. The two tanks achieve zoned water supply for different washing stages. The first water tank component can store tap water or water treated by a water purifier, mainly used in the main cleaning stage, while the second water tank component can store purified water or distilled water, mainly used in the cleanup stage. Compared to a single water tank component, the dual-tank design allows for zoned storage and on-demand switching of water of different qualities, better meeting the differentiated requirements for cleaning water quality in different scenarios, thereby enhancing the adaptability and operational flexibility of the entire water system during the cleaning process.

[0006] In one embodiment, the housing assembly further includes a drain outlet and a drainage component disposed on the housing assembly. The cleaning chamber, the drainage component, and the drain outlet are sequentially connected. By providing the drain outlet and drainage component, a complete drainage path is formed from the cleaning chamber to the drain outlet. Wastewater generated during the cleaning process can be discharged from the cleaning chamber in a timely manner through this path, avoiding prolonged retention of wastewater in the cleaning chamber and preventing stains in the wastewater from re-adhering to the surface of the object being cleaned. This ensures that subsequent cleaning steps are not affected by the wastewater from the preceding process, guaranteeing the continuity of the cleaning process and the final cleaning quality.

[0007] In one embodiment, the first water tank assembly has a first carrying cavity, and the second water tank assembly has a second carrying cavity, with the volume of the first carrying cavity being larger than that of the second carrying cavity. This design, where the first carrying cavity is larger than the second carrying cavity, provides a basis for adapting to the water volume and quality requirements of different washing stages. The first carrying cavity can hold a larger volume of water, while the second carrying cavity can hold a smaller amount of water with better quality. Combined with the control of the on / off state of the two interfaces and the washing cavity by the water inlet assembly, the two water tanks can each hold washing water of different qualities. Specifically, the final washing stage uses water with better quality, resulting in a cleaner and healthier wash. The two water tanks achieve separate water supply for different washing stages: the first water tank assembly can store tap water or water from a water purifier, primarily meeting the main washing needs; the second water tank assembly can store purified water or distilled water, focusing on achieving the cleaning function. The first water tank assembly needs to provide sufficient water during the main washing stage, while the second water tank assembly is only used for cleaning treatment in the final washing stage. This allows the water supply and water quality requirements to be better matched to each stage of the cleaning process, ensuring sufficient water supply during the main washing stage and meeting the demand for high-quality water in subsequent washing stages. This enhances the flexibility and practicality of the dual water tank design in adapting to different cleaning scenarios and also improves the rational utilization efficiency of water resources in different cleaning stages.

[0008] In one embodiment, the housing assembly includes a top cover assembly, an outer shell assembly, and an inner liner assembly. The outer shell assembly has the first interface, the second interface, and the drain outlet. The top cover assembly is disposed on the outer shell assembly. The top cover assembly and the outer shell assembly enclose an inner liner cavity. The inner liner assembly is disposed on the outer shell assembly and located within the inner liner cavity. The inner liner assembly has the cleaning chamber. The outer shell assembly and the inner liner assembly enclose an installation cavity on the side away from the top cover assembly. The water inlet assembly and the drain assembly are disposed on the inner liner assembly and are both located within the installation cavity. The housing assembly adopts a split structure consisting of a top cover assembly, an outer shell assembly, and an inner liner assembly. Each assembly has a clear functional division. The inner liner cavity formed by the top cover assembly and the outer shell assembly provides a stable installation space for the inner liner assembly. The interfaces and drain outlets on the outer shell assembly facilitate connection with other components. This structural design reduces the difficulty of manufacturing each component and also facilitates precise positioning and installation of each component during assembly. The installation cavity formed by the outer shell assembly and the inner liner assembly centrally houses the water inlet and drainage components, effectively protecting these core functional components from damage caused by external environmental factors. It also makes the internal structure layout of the entire water system more compact and orderly, reducing space occupation and making it easier to operate when the water inlet and drainage components need to be inspected or maintained.

[0009] In one embodiment, the inner liner assembly includes an inner liner body and a water cup. The water cup is disposed on the inner liner body, and the water cup and the inner liner body cooperate to form the cleaning chamber. The water cup is connected to the water inlet assembly. In the inner liner assembly, the assembly structure of the water cup and the inner liner body provides a precise positioning basis for the installation of the water inlet assembly, enabling the water inlet assembly to form a stable structural fit with the water cup. This facilitates quick and accurate location of the connection position during assembly, improving assembly efficiency. Simultaneously, the placement of the water cup ensures a reasonable structural connection between the water flow output end of the water inlet assembly and the cleaning chamber, resulting in a more regular water circuit layout, reducing installation interference caused by intersecting pipes, and facilitating overall planning and layout of the water system.

[0010] In one embodiment, the inner tank assembly further includes a filter assembly disposed on the inner tank body and located within the cleaning chamber, the filter assembly covering the water cup. The filter assembly covering the water cup filters the water flowing through the relevant area of ​​the water cup, effectively intercepting particulate impurities and suspended solids in the water. This not only prevents impurities from adhering to the surface of the object being cleaned and affecting cleanliness, but also prevents impurities from entering the water system and causing blockage or wear of components, thereby ensuring stable cleaning results and maintaining the long-term stable operation of the water system.

[0011] In one embodiment, the housing assembly further includes a bottom cover assembly disposed on the outer housing assembly and covering the mounting cavity. The bottom cover assembly, covering the mounting cavity, forms a sealed protection, effectively preventing dust, debris, water droplets, and other external environmental contaminants from entering the mounting cavity. This avoids contamination or damage to the water inlet and drainage components located within the mounting cavity, extending the service life of these components. Simultaneously, the detachable connection between the bottom cover assembly and the outer housing assembly allows for easy opening of the bottom cover assembly when inspection, maintenance, or replacement of components within the mounting cavity is required, providing a convenient access for operation.

[0012] In one embodiment, the first water tank assembly and the second water tank assembly are integrally formed and detachably mounted on the housing assembly. The integrally formed design of the first and second water tank assemblies reduces the connection structure between components, enhances the stability and sealing of the overall structure, and reduces the risk of leakage. At the same time, the integrally formed dual water tanks still retain their detachable characteristics, making it convenient for users to remove and place them as a whole for water filling or cleaning operations, simplifying the maintenance process and improving ease of use.

[0013] In one embodiment, the water inlet assembly includes a control valve, a flow meter, an inlet pump, and a cleaning pump. The control valve, flow meter, inlet pump, and cleaning pump are mounted on the housing assembly and connected sequentially. The control valve controls whether the first and second interfaces are connected to or disconnected from the cleaning chamber. Both ends of the cleaning pump are connected to the cleaning chamber. The water inlet assembly integrates multiple functional components such as the control valve, flow meter, inlet pump, and cleaning pump, and these components work together to form a complete water inlet and cleaning power system. The control valve can precisely control the connection and disconnection between the first and second interfaces and the cleaning chamber, enabling the water from the two water tank assemblies to be switched and delivered to the cleaning chamber as needed. The flow meter can monitor and measure the amount of water entering the cleaning chamber in real time, providing accurate water volume data for the system and facilitating the control of the total water intake. The water pump provides sufficient power for the water flow, ensuring that the water can be smoothly delivered from the water tank assembly to the cleaning chamber. The cleaning pump is connected to the cleaning chamber at both ends, which can promote the circulation of water within the cleaning chamber. The synergistic effect of these components allows the water system to precisely control the water source, water volume, and water flow status according to the needs of different cleaning stages, thereby effectively improving the cleaning effect and water resource utilization efficiency.

[0014] In one embodiment, the control valve includes a first valve body, a second valve body, a first inlet pipe, a second inlet pipe, and a first outlet pipe. The first inlet pipe is connected to the first interface, the second inlet pipe is connected to the second interface, one end of the first outlet pipe is connected to the flow meter, and the other end of the first outlet pipe is connected to both the first and second valve bodies. In the structural design of the control valve, the first and second inlet pipes are connected to the first and second interfaces respectively, forming two independent inlet branches. The first and second valve bodies can independently control these two branches, realizing the individual on / off operation of the water flow in the two water tank components. The first outlet pipe collects the water flow controlled by the valve body and delivers it to the flow meter. This structural design ensures the stability and reliability of the water flow during the switching process, enabling precise switching of the water flow in the two water tank components and meeting the precise control requirements for different water sources during the cleaning process.

[0015] In one embodiment, the flow meter is detachably mounted on the housing assembly. This detachable mounting eliminates the need for extensive disassembly of the entire water system when the flow meter malfunctions and requires repair or replacement due to reaching the end of its service life. Instead, the flow meter can be removed individually for operation, reducing the difficulty of repair and replacement, minimizing maintenance time and costs, and improving the convenience and operability of the entire water system during maintenance.

[0016] In one embodiment, the flow meter is located at the bottom of the cleaning chamber. The flow meter has a third inlet pipe and a second outlet pipe at its two ends. The third inlet pipe is positioned at a lower level than the second outlet pipe. The connection point between the second outlet pipe and the flow meter is near the bottom of the cleaning chamber. The third inlet pipe connects to the first outlet pipe, and the second outlet pipe connects to the water pump. This height difference design, with the flow meter at the bottom of the cleaning chamber and the third inlet pipe at a lower level than the second outlet pipe, allows the water to flow relatively smoothly upon entering the flow meter, reducing the impact and turbulence caused by sudden entry. Simultaneously, the connection point between the second outlet pipe and the flow meter is near the bottom of the cleaning chamber, facilitating the expulsion of internal air during system operation and preventing air accumulation within the flow meter from affecting flow detection accuracy. Furthermore, this design further reduces the flow velocity of the water, allowing the water to pass through the flow meter more smoothly, ensuring the accuracy of the flow meter's flow detection. The water can also enter the inlet pump more smoothly after flowing out of the flow meter, reducing bends and resistance points in the water path and reducing energy loss during water transmission.

[0017] In one embodiment, the flow meter is provided with a flow cavity, the wall of which is a smooth curved surface. The flow cavity wall is designed as a smooth curved surface without steps. When water flows through the flow cavity, this not only reduces the water flow resistance caused by unevenness in the cavity wall and lowers energy loss during the flow process, thus saving system energy consumption, but also allows air to escape smoothly and without obstruction within the cavity. This avoids air accumulation interfering with water flow stability, reduces flow meter measurement pulse data deviation caused by air influence, provides more stable water flow conditions for flow meter detection, and further improves the accuracy and reliability of flow detection.

[0018] The second aspect of this application discloses a cleaning machine, which includes the aforementioned cleaning machine water system.

[0019] The aforementioned cleaning machine features a dual-tank system for flexible water supply, adapting to the water quality and quantity requirements of different cleaning stages. It is easy to operate and highly efficient in switching between systems. At the same time, the system structure is rationally designed to ensure the stability and cleaning effect of the cleaning process, enhancing the machine's adaptability and user experience in diverse cleaning scenarios.

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] The following description, with reference to the accompanying drawings, describes the water system and cleaning machine of some embodiments of the present invention.

[0041] Example 1

[0042] like Figures 1 to 12As shown, this embodiment discloses a water circuit system for a cleaning machine, including a housing assembly 1, which has a first interface 101, a second interface 102, and a cleaning chamber 103; a first water tank assembly 2, which has a first water outlet 201 connected to the first interface 101; a second water tank assembly 3, which has a second water outlet 301 connected to the second interface 102; and a water inlet assembly 4, which is mounted on the housing assembly 1 and connected to the cleaning chamber 103. The water inlet assembly 4 is also connected to the first interface 101 and the second interface 102, and can control the connection or disconnection of the first interface 101 and the second interface 102 with the cleaning chamber 103.

[0043] The water system of the cleaning machine disclosed in this application connects the first water tank assembly 2 and the second water tank assembly 3 to the first interface 101 and the second interface 102 of the housing assembly 1 via the first water inlet 201 and the second water inlet 301, respectively. This provides a basic guarantee for water filling and cleaning operations and simplifies the operation process. Simultaneously, the water inlet assembly 4 can effectively control the on / off state between the first interface 101 and the second interface 102 and the cleaning chamber 103. This function allows the system to use different water qualities in the two tanks according to the characteristics of different cleaning objects and the specific needs of different cleaning stages. The final cleaning stage uses water of higher quality, resulting in cleaner and healthier water. The two tanks achieve zoned water supply for different washing stages. The first water tank assembly 2 can store tap water or water treated by a water purifier, mainly used in the main cleaning stage, while the second water tank assembly 3 can store purified water or distilled water, mainly used in the cleaning stage. Compared to a single water tank assembly, the dual-tank design enables partitioned storage and on-demand switching of water of different qualities, better meeting the differentiated requirements for cleaning water quality in different scenarios, thereby enhancing the adaptability and operational flexibility of the entire water system during the cleaning process.

[0044] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 also has a drain outlet 104, and also includes a drain assembly 5, which is disposed on the housing assembly 1. The cleaning chamber 103, the drain assembly 5, and the drain outlet 104 are sequentially connected. By setting the drain outlet 104 and the drain assembly 5, a complete drainage path is formed from the cleaning chamber 103 to the drain outlet 104. Wastewater generated during the cleaning process can be discharged from the cleaning chamber 103 in a timely manner through this path, avoiding the wastewater from remaining in the cleaning chamber 103 for a long time, preventing stains in the wastewater from re-adhering to the surface of the object being cleaned, ensuring that subsequent cleaning steps are not affected by the wastewater from the preceding steps, and guaranteeing the continuity of the cleaning process and the final cleaning quality.

[0045] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first water tank assembly 2 is provided with a first bearing cavity 202, and the second water tank assembly 3 is provided with a second bearing cavity 302, the volume of the first bearing cavity 202 being larger than the volume of the second bearing cavity 302. The design that the first bearing cavity 202 is larger than the second bearing cavity 302 provides a basis for adapting to the water volume and quality requirements of different washing stages. The first bearing cavity 202 can hold more water, while the second bearing cavity 302 can store a small amount of water with better quality. Combined with the control of the two interfaces and the washing cavity 103 by the water inlet assembly 4, the two water tanks can respectively hold washing water of different qualities. The final washing stage uses water with better quality, resulting in cleaner and healthier water. The two water tanks achieve separate water supply for different washing stages: the first water tank assembly 2 can store tap water or water from a water purifier, mainly meeting the main washing needs; the second water tank assembly 3 can store purified water or distilled water, focusing on achieving the cleaning function. The first water tank assembly 2 needs to provide sufficient water during the main washing stage, while the second water tank assembly 3 is only used for cleaning treatment in the final washing stage. This allows the water supply and water quality requirements to be better matched to each stage of the cleaning process, ensuring sufficient water supply during the main washing stage and meeting the demand for high-quality water in subsequent washing stages. This enhances the flexibility and practicality of the dual water tank design in adapting to different cleaning scenarios and also improves the rational utilization efficiency of water resources in different cleaning stages.

[0046] like Figures 1 to 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the shell assembly 1 includes a top cover assembly 11, an outer shell assembly 12 and an inner liner assembly 13. The outer shell assembly 12 is provided with a first interface 101, a second interface 102 and a drain outlet 104. The top cover assembly 11 is disposed on the outer shell assembly 12. The top cover assembly 11 and the outer shell assembly 12 enclose to form an inner liner cavity 1201. The inner liner assembly 13 is disposed on the outer shell assembly 12 and located within the inner liner cavity 1201. The inner liner assembly 13 is provided with a cleaning chamber 103. The outer shell assembly 12 and the inner liner assembly 13 enclose to the side away from the top cover assembly 11 to form an installation cavity 1202. The water inlet assembly 4 and the drain assembly 5 are disposed on the inner liner assembly 13 and are both located within the installation cavity 1202. The shell assembly 1 adopts a split structure of top cover assembly 11, outer shell assembly 12 and inner liner assembly 13. Each component has a clear functional division. The inner liner cavity 1201 formed by the top cover assembly 11 and outer shell assembly 12 provides a stable installation space for the inner liner assembly 13. The interface and drain port 104 on the outer shell assembly 12 facilitate connection with other components. This structural design reduces the difficulty of manufacturing each component and also facilitates precise positioning and installation of each component during assembly. The installation cavity 1202 formed by the outer shell assembly 12 and inner liner assembly 13 houses the water inlet assembly 4 and the drain assembly 5, effectively protecting these core functional components and preventing damage from external environmental factors. It also makes the internal structure layout of the entire water system more compact and orderly, reducing space occupation. When it is necessary to inspect or maintain the water inlet assembly 4 and the drain assembly 5, it is also easier to operate.

[0047] In addition to the features of the above embodiments, this embodiment further specifies that: the inner liner assembly 13 includes an inner liner body 131 and a water cup 132. The water cup 132 is disposed on the inner liner body 131, and the water cup 132 and the inner liner body 131 cooperate to form a cleaning chamber 103. The water cup 132 is connected to the water inlet assembly 4. In the inner liner assembly 13, the assembly structure of the water cup 132 and the inner liner body 131 provides a precise positioning basis for the installation of the water inlet assembly 4, enabling the water inlet assembly 4 to form a stable structural fit with the water cup 132, facilitating quick and accurate location of the connection position during assembly and improving assembly efficiency. At the same time, the setting of the water cup 132 enables a reasonable structural connection between the water flow output end of the water inlet assembly 4 and the cleaning chamber 103, making the water circuit layout more regular, reducing installation interference caused by pipe intersections, and facilitating the overall planning and layout of the water circuit system.

[0048] In addition to the features of the above embodiments, this embodiment further specifies that: the inner tank assembly 13 also includes a filter assembly 133, which is disposed on the inner tank body 131 and located within the cleaning chamber 103, and covers the water cup 132. The filter assembly 133, covering the water cup 132, can filter the water flowing through the relevant area of ​​the water cup 132, effectively intercepting particulate impurities, suspended solids, etc. in the water. This not only prevents impurities from adhering to the surface of the object being cleaned and affecting cleanliness, but also prevents impurities from entering the water system and causing component blockage or wear, thereby ensuring stable cleaning results and maintaining the long-term stable operation of the water system.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 also includes a bottom cover assembly 14, which is disposed on the outer housing assembly 12 and covers the mounting cavity 1202. The bottom cover assembly 14 covers the mounting cavity 1202, forming a closed protection for the mounting cavity 1202, which can effectively prevent dust, debris, water droplets, etc. from the external environment from entering the interior of the mounting cavity 1202, avoiding these substances from contaminating or damaging the water inlet assembly 4 and the drainage assembly 5 located in the mounting cavity 1202, and extending the service life of these components; at the same time, the detachable connection between the bottom cover assembly 14 and the outer housing assembly 12 makes it easy to open the bottom cover assembly 14 when it is necessary to inspect, maintain or replace the components in the mounting cavity 1202, providing a convenient passage for operation.

[0050] like Figure 1 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first water tank assembly 2 and the second water tank assembly 3 are integrally formed and detachably mounted on the housing assembly 1. The integrally formed design of the first water tank assembly 2 and the second water tank assembly 3 reduces the connection structure between components, enhances the stability and sealing of the overall structure, and reduces the risk of leakage; at the same time, the integrally formed dual water tanks still retain the detachable characteristic, making it convenient for users to remove and place them as a whole for water addition or cleaning operations, simplifying the maintenance process and improving ease of use.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water inlet assembly 4 includes a control valve 41, a flow meter 42, a water inlet pump 43, and a cleaning pump 44. The control valve 41, flow meter 42, water inlet pump 43, and cleaning pump 44 are disposed on the housing assembly 1 and connected in sequence. The control valve 41 can control the connection or disconnection between the first interface 101 and the second interface 102 and the cleaning chamber 103. The two ends of the cleaning pump 44 are respectively connected to the cleaning chamber 103. The water inlet assembly 4 integrates multiple functional components such as the control valve 41, flow meter 42, water inlet pump 43, and cleaning pump 44. The components work together to form a complete water inlet and cleaning power system. The control valve 41 can precisely control the connection and disconnection between the first interface 101 and the second interface 102 and the cleaning chamber 103, enabling the water in the two water tank components to be switched and delivered to the cleaning chamber 103 as needed; the flow meter 42 can monitor and measure the amount of water entering the cleaning chamber 103 in real time, providing accurate water volume data for the system and facilitating the control of the total water intake; the water pump 43 provides sufficient power for the water flow, ensuring that the water flow can be smoothly delivered from the water tank components to the cleaning chamber 103; the cleaning pump 44 is connected to the cleaning chamber 103 at both ends, which can promote the water circulation in the cleaning chamber 103. The synergistic effect of these components enables the water system to precisely control the water source, water volume and water flow status according to the needs of different cleaning stages, thereby effectively improving the cleaning effect and water resource utilization efficiency.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that: the control valve 41 includes a first valve body 411, a second valve body 412, a first inlet pipe 413, a second inlet pipe 414 and a first outlet pipe 415, the first inlet pipe 413 is connected to the first interface 101, the second inlet pipe 414 is connected to the second interface 102, one end of the first outlet pipe 415 is connected to the flow meter 42, and the other end of the first outlet pipe 415 is connected to the first valve body 411 and the second valve body 412 respectively. In the structural design of the control valve 41, the first inlet pipe 413 and the second inlet pipe 414 are connected to the first interface 101 and the second interface 102 respectively, forming two independent inlet branches. The first valve body 411 and the second valve body 412 can independently control these two branches, realizing the individual on / off operation of the water flow in the two water tank components. The first outlet pipe 415 collects the water flow controlled by the valve body and delivers it to the flow meter 42. This structural design ensures the stability and reliability of the water flow during the switching process, and can accurately realize the switching of the water flow in the two water tank components, meeting the precise control requirements of different water sources during the cleaning process.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that the flow meter 42 is detachably mounted on the housing assembly 1. The detachable mounting of the flow meter 42 on the housing assembly 1 eliminates the need for extensive disassembly of the entire water system when the flow meter 42 malfunctions and requires repair or replacement due to reaching the end of its service life. Only the flow meter 42 needs to be removed for operation, reducing the difficulty of repair and replacement, decreasing the time and cost required for maintenance, and improving the convenience and operability of the entire water system during maintenance.

[0054] In addition to the features of the above embodiments, this embodiment further specifies that: the flow meter 42 is located at the bottom of the cleaning chamber 103, and the flow meter 42 is provided with a third water inlet pipe 421 and a second water outlet pipe 422 at its two ends respectively. The horizontal height of the third water inlet pipe 421 is lower than the height of the second water outlet pipe 422. The connection between the second water outlet pipe 422 and the flow meter 42 is close to the bottom of the cleaning chamber 103. The third water inlet pipe 421 is connected to the first water outlet pipe 415, and the second water outlet pipe 422 is connected to the water pump 43. The flow meter 42 is located at the bottom of the cleaning chamber 103, and the third inlet pipe 421 is at a lower horizontal level than the second outlet pipe 422. This height difference design allows the water to flow relatively smoothly when entering the flow meter 42, reducing the impact and turbulence caused by sudden entry. Simultaneously, the connection between the second outlet pipe 422 and the flow meter 42 is close to the bottom of the cleaning chamber 103. This structure facilitates the expulsion of internal air during water system operation, preventing air accumulation within the flow meter 42 from affecting flow detection accuracy. Furthermore, this design further reduces the water flow velocity, allowing the water to pass more smoothly through the flow meter 42, ensuring the accuracy of flow detection. After exiting the flow meter 42, the water flows more smoothly into the inlet pump 43, reducing bends and resistance points in the water path and minimizing energy loss during transmission.

[0055] In addition to the features of the above embodiments, this embodiment further specifies that: the flow meter 42 is provided with a flow cavity 4201, and the cavity wall of the flow cavity 4201 is a smooth curved surface. The flow cavity 4201 of the flow meter 42 is designed with a smooth curved surface and no step structure. When water flows through the flow cavity 4201, it not only reduces the water flow resistance caused by uneven cavity walls and reduces energy loss during the flow process, thus saving system energy consumption; at the same time, the smooth, stepless curved surface structure allows air to be discharged smoothly and without obstruction within the cavity, avoiding air accumulation from interfering with water flow stability, reducing the deviation of the flow meter 42's measurement pulse data caused by air influence, providing more stable water flow conditions for the flow meter 42's flow detection, and further improving the accuracy and reliability of flow detection.
