The working surface of the cleaning device 100 can be a floor, a wall, a door or window surface, a furniture surface, etc., wherein the floor surface can be but not limited to a floor surface, a tile surface, a cement surface, a carpet, etc.

[0045] Please refer to Figures 1 to 3. The cleaning device 100 of the embodiment of the present application includes a main body 10, a sewage tank 20 and a water outlet element 30, wherein the sewage tank 20 is arranged on the main body 10, the sewage tank 20 forms a chamber 201, the sewage tank 20 is fluidically connected to the main body 10, and the water outlet element 30 is arranged in the chamber 201. The water outlet element 30 is used to communicate with an external water source through the main body 10 to spray external cleaning liquid into the chamber 201.

[0046] In the cleaning device 100 of the present embodiment, an external water source is connected to the sewage tank 20 via the main unit 10, and the sewage tank 20 is cleaned by the water outlet assembly. This simple structure and compact connection allow the sewage tank 20 to be cleaned automatically, saving manpower and enhancing the user experience. Furthermore, the water outlet assembly utilizes the water pressure of the external cleaning fluid to clean the cavity, eliminating the need for a water pump, reducing manufacturing costs, saving space, and facilitating miniaturization of the cleaning device 100.

[0047] Specifically, the main unit 10 and the sewage tank 20 are connected by a fluid path, which can be achieved by connecting the main unit 10 and the sewage tank 20 via parts or structures such as hoses, pipes, chambers 201, holes, and channels, allowing liquids or other fluids to pass smoothly from the main unit 10 into the sewage tank 20 or from the sewage tank 20 into the main unit 10. The main unit 10 can be provided with a handle 15 and a cleaning device 16, and the user can grasp and operate the handle 15 to move the main unit 10. The cleaning device 16 can include cleaning tools such as a mop and a brush, and the cleaning device 16 can contact and clean the work surface during the movement of the main unit 10. The cleaning device 100 of the embodiment of the present application has a side facing the work surface as the bottom 12, and a side opposite to the bottom 12 and away from the work surface as the top 13, with the direction relative to the bottom 12 and the top 13 being the vertical direction. The cleaning device 16 can be provided at the bottom 12 of the main unit 10, and the handle 15 can be provided at the top 13 of the main unit 10.

[0048] The sewage tank 20 can be arranged transversely with the main unit 10, and is used to collect and collect sewage generated after the cleaning device 16 cleans the working surface. The transverse direction can be a horizontal direction and is perpendicular to the above-mentioned vertical direction. The cross-sectional shape of the sewage tank 20 can include but is not limited to a circle, a semicircle, an ellipse, a square, a rectangle, a polygon, a runway shape, or other irregular shapes containing both straight edges and curved edges. In the present application, the sewage tank 20 is described as a cylindrical structure with a cross-sectional shape that is approximately semicircular. The inner wall 21 of the sewage tank 20 surrounds a chamber 201, and the chamber 201 can be open. A cover 23 can be provided at one open end of the sewage tank 20, and the cover 23 can be detachably connected to the sewage tank 20. The inner wall 21 of the sewage tank 20 includes a bottom surface 2102 opposite to the cover 23 and a vertical surface 2101 connected to the bottom surface 2102. The vertical surface 2101 of the sewage tank 20 may be vertically arranged, and the bottom surface 2102 of the sewage tank 20 may be close to the cleaning device 16 and may be horizontally opposite to the working surface.

[0049] Please refer to Figures 2 and 6. In some embodiments, the host 10 is provided with a first liquid circuit interface 11, and the sewage tank 20 is provided with a second liquid circuit interface 22. When the first liquid circuit interface 11 and the second liquid circuit interface 22 are plugged into each other, the host 10 and the sewage tank 20 are fluidically connected. When the first liquid circuit interface 11 and the second liquid circuit interface 22 are disconnected from each other, the first liquid circuit interface 11 and the second liquid circuit interface 22 are each disconnected.

[0050] In this way, the first liquid path interface 11 and the second liquid path interface 22 are plugged into each other to achieve liquid communication between the host 10 and the sewage tank 20 , and support detachable connection between the host 10 and the sewage tank 20 .

[0051] Specifically, the first and second fluidic interface 11, 22 have identical cross-sectional shapes. When the first and second fluidic interface 11, 22 are connected, the first fluidic interface 11 can be inserted into the second fluidic interface 22. The first and second fluidic interface 11, 22 are sealed to prevent fluid in the fluid path from spilling out of the connection. In other embodiments, as shown in FIG6 , the second fluidic interface 22 can also be inserted into the first fluidic interface 11.

[0052] When the first liquid path interface 11 and the second liquid path interface 22 are inserted into each other, the main unit 10 and the sewage tank 20 are installed together, and the liquid path between the main unit 10 and the sewage tank 20 is in fluid communication. External cleaning liquid can pass through the liquid channel 17 in the main unit 10 and enter the sewage tank 20 through the connection between the first liquid path interface 11 and the second liquid path interface 22. When the first liquid path interface 11 and the second liquid path interface 22 are removed from each other, either the first liquid path interface 11 is removed from the second liquid path interface 22 or the second liquid path interface 22 is removed from the first liquid path interface 11, the liquid path between the main unit 10 and the sewage tank 20 is disconnected, and the main unit 10 can be separated from the sewage tank 20.

[0053] Please refer to FIG. 2 , FIG. 3 and FIG. 6 . In some embodiments, the second liquid path interface 22 is in communication with the water outlet element 30 .

[0054] In this way, when the second liquid circuit interface 22 is plugged into the first liquid circuit interface 11 , the host 10 can connect the water outlet element 30 to an external water source.

[0055] Specifically, a liquid channel 17 may be provided inside the host 10 for external cleaning liquid to circulate in the host 10. In some embodiments, a second water outlet 19 may be provided on the cleaning device 16 to connect to the liquid channel 17 of the host 10, and external cleaning liquid may enter the liquid channel 17 of the host 10 from the second water outlet 19. A second water inlet 18 is provided at one end of the liquid channel 17, and a first liquid path interface 11 is provided at the other end. The second water inlet 18 is provided toward the cleaning device 16 and connected to the second water outlet 19. The first liquid path interface 11 is plugged into the second liquid path interface 22. The external cleaning liquid enters the liquid path channel from the connection between the second water outlet 19 and the second water inlet 18, passes through the liquid path channel, enters the water outlet element 30 through the connection between the first liquid path interface 11 and the second liquid path interface 22, and flows out of the water outlet element 30 into the sewage tank 20.

[0056] 3 and 4 , in some embodiments, the water outlet element 30 is installed on the inner wall 21 of the sewage tank 20 and surrounds the inner wall 21 of the chamber 201 along the circumference of the chamber 201 .

[0057] In this way, the water outlet element 30 surrounds the inner wall 21 of the chamber 201 and can fully and evenly spray water onto the inner wall 21 of the chamber 201, thereby achieving a better cleaning effect.

[0058] Specifically, the water outlet element 30 is disposed on the vertical surface 2101 of the inner wall 21, and can be located at an end away from the bottom surface 2102. The water outlet element 30 utilizes the water pressure from an external water source and the gravity of the external cleaning liquid to spray the external cleaning liquid into the chamber 201. The outer contour of the water outlet element 30 matches the cross-sectional shape of the sewage tank 20 and can extend along the circumference of the chamber 201, aligned with the vertical surface 2101. The water outlet element 30 can surround the inner wall 21, and can encompass a full circle, half a circle, three-quarters of a circle, etc.

[0059] Please refer to Figures 3 to 5. In some embodiments, the water outlet element 30 is provided with a water outlet groove 31. A first water outlet 32 ​​is formed on the side of the water outlet groove 31 facing the bottom 12 of the sewage tank 20. The water outlet groove 31 surrounds the chamber 201 along the circumference of the chamber 201. The first water outlet 32 ​​is used to spray external cleaning liquid toward the inner wall 21 of the chamber 201.

[0060] In this way, the external cleaning liquid flows out from the water outlet trough 31 and evenly washes the inner wall 21 of the sewage tank 20 .

[0061] Specifically, the water outlet 31 and the first water outlet 32 ​​can both be arranged around the chamber 201, and the contour shapes of the first water outlet 32 ​​and the water outlet 31 can be consistent with the cross-sectional contour shape of the inner wall 21 of the sewage tank. The water outlet 31 can accommodate a smaller amount of water and guide the external cleaning liquid flowing out of the second liquid path interface 22 to flow around the inner wall 21. The first water outlet 32 ​​can be set vertically so that the water in the water outlet element 30 can flow out smoothly and quickly and wash the inner wall 21. The first water outlet 32 ​​can also be set diagonally downward, which is also conducive to the smooth flow of external cleaning liquid and spraying onto the inner wall 21 of the chamber 201, while increasing the water pressure and improving the cleaning effect. The cross section of the first water outlet 32 ​​refers to the cross section perpendicular to the direction of water spraying.

[0062] In some embodiments, the water outlet element 30 is formed with multiple second water outlets (not shown) arranged around the chamber 201, and the multiple second water outlets (not shown) are arranged at intervals along the circumference of the chamber 201, and the second water outlets (not shown) are set toward the inner wall 21 of the chamber 201.

[0063] In this way, the external cleaning liquid is sprayed toward the inner wall 21 of the chamber 201 through the outlet hole, thereby evenly washing the inner wall 21 of the sewage tank 20 .

[0064] Specifically, the second water outlets (not shown) can be evenly spaced along the circumference of the chamber 201, or more densely arranged. The second water outlets (not shown) and the first water outlets 32 can be arranged alternatively.

[0065] 3 , in some embodiments, the water outlet element 30 is fixedly connected to the sewage tank 20. In other embodiments, the water outlet element 30 is detachably connected to the sewage tank 20.

[0066] In this way, the connection modes of the water outlet element 30 and the sewage tank 20 are more diversified, adapting to different usage scenarios and user habits.

[0067] Specifically, the water outlet element 30 is detachably connected to the sewage tank 20 and can be selected by the user as an optional part of the main unit 10. It can also be removed separately for inspection, cleaning, repair, or replacement during maintenance. The water outlet element 30 can be connected to the sewage tank 20 by at least one of a snap connection, an adhesive connection, a threaded connection, a fastener connection, and a weld. The installation position of the water outlet element 30 relative to the sewage tank 20 is fixed within a certain range. For example, the water outlet element 30 surrounds the inner wall 21 at the top 13 of the sewage tank 20. This ensures that the position of the water outlet element 30 spraying water onto the inner wall 21 is fixed, allowing the water outlet element 30 to evenly and fully spray the external cleaning liquid onto the inner wall 21, ensuring a stable cleaning effect.

[0068] Please refer to Figure 2. The cleaning system 1000 of the embodiment of the present application includes a base 200 and a cleaning device 100 of any of the above embodiments. The main unit 10 is fluidically connected to the base 200, the base 200 is connected to an external water source, and the sewage tank 20 is connected to the external water source through the main unit 10 and the base 200 in turn.

[0069] In this way, the base 200 is connected to the external water source, and there is no need to manually connect the external cleaning liquid, so the installation space of the base 200 is effectively utilized.

[0070] Specifically, the base 200 is connected to an external water source, such as a household faucet, water pipe, or water valve. Alternatively, the base 200 can be connected to an external water supply device, such as a water tank or water vat. The external cleaning liquid can be tap water, water provided by an external device, or a mixture of tap water and a detergent. In some embodiments, the base 200 is directly connected to a household faucet, and tap water, acting as the external cleaning liquid, passes through the base 200 and the main unit 10, and then enters the sewage tank 20. Using tap water to clean the sewage tank 20 eliminates the need for the user to remove or refill the sewage tank 20, simplifying operation.

[0071] Please refer to FIG. 8 . In some embodiments, the base 200 is provided with a water guide component 210 and a control valve 220 . The water guide component 210 is in fluid communication with the host 10 . The control valve 220 is used to control the on / off of the water guide component 210 .

[0072] In this way, the water inlet and the cleaning process can be controlled according to the state of the sewage tank 20 through the control valve 220, so that the sewage tank 20 can be cleaned immediately and timely.

[0073] Specifically, the water-guiding assembly 210 may be provided with a passageway, such as a hose, a rigid pipe, or a chamber, for liquid circulation. The water-guiding assembly 210 may be fluidically connected to the host computer 10 via the third fluid-path interface 230. The control valve 220 may be a solenoid valve, electrically connected to the host computer 10 and / or the sewage tank 20, capable of receiving and feeding back electrical signals. When the sewage tank 20 is highly contaminated and requires cleaning, the host computer 10 may transmit a cleaning signal to the control valve 220. Upon receiving the cleaning signal, the control valve 220 may control the water-guiding assembly 210 to connect to an external water source and deliver external cleaning fluid to the host computer 10. During the cleaning process, the host computer 10 or the sewage tank 20 may obtain the cleaning status and progress of the sewage tank 20 and transmit this status information to the control valve 220. The control valve 220 may control the water intake based on the sewage tank 20 status information. For example, if the sewage tank 20 cleaning effect is unsatisfactory, the control valve 220 may increase the water intake to enhance cleaning effectiveness. Alternatively, when cleaning is complete, the control valve 220 may disconnect the water-guiding assembly 210.

[0074] Please refer to Figures 2, 7 and 9. In some embodiments, the base 200 is provided with a third liquid circuit interface 230 on the side facing the host 10, and the host 10 is provided with a fourth liquid circuit interface 14 on the side facing the base 200. When the fourth liquid circuit interface 14 and the third liquid circuit interface 230 are plugged into each other, the host 10 and the base 200 are liquid-connected.

[0075] In this way, when the third liquid path interface 230 is plugged into the fourth liquid path interface 14, the main unit 10 and the base 200 are fluidically connected; when the third liquid path interface 230 is separated from the fourth liquid path interface 14, the fluid paths between the main unit 10 and the base 200 are not connected, making it easy to connect and disconnect the main unit 10 and the base 200.

[0076] Specifically, the cleaning device 16 is located at the bottom 12 of the main unit 10. The cleaning device 16 may form a side of the main unit 10 facing the base 200, and the fourth fluid circuit interface 14 may be disposed on the cleaning device 16. The side of the main unit 10 facing the base 200 may form a horizontal surface, and the cleaning device 16 may include this horizontal surface, so that the main unit 10 can be placed on the base 200 via the horizontal surface. When the main unit 10 is placed on the base 200, the third fluid circuit interface 230 and the fourth fluid circuit interface 14 are plugged into each other. The third fluid circuit interface 230 may be inserted into the fourth fluid circuit interface 14, or the fourth fluid circuit interface 14 may be inserted into the third fluid circuit interface 230.

[0077] When the host 10 and the cleaning device 16 need to be removed from the base 200, the third liquid path interface 230 is pulled out from the fourth liquid path interface 14, or the fourth liquid path interface 14 is pulled out from the third liquid path interface 230, and the connection between the host 10 and the base 200 is disconnected, which is easy to operate.

[0078] Referring to FIG. 2 and FIG. 8 , in some embodiments, the water guide assembly 210 includes a water inlet 211 for connecting to an external water source. The water inlet 211 and the third liquid path interface 230 are located on different sides of the base 200 .

[0079] In this way, by connecting to an external water source through the water inlet 211 , the cleaning system 1000 can use an external cleaning liquid and utilize municipal water pressure to clean the sewage tank 20 .

[0080] Specifically, the water inlet 211 can be a valve-like component, such as an inlet valve. The water inlet 211 can also be an open component, such as a hose, pipe, or the open end of the chamber 201. The water inlet 211 can be connected to a faucet at an external water source. When the sewage tank 20 needs to be cleaned, the faucet is turned on, and water flows through the base 200 and the main unit 10, enters the water outlet element 30, and is sprayed out from the first water outlet 32 ​​or the second water outlet onto the inner wall 21 of the sewage tank 20, thereby cleaning the sewage tank 20.

[0081] The water guide assembly 210 also includes a flow guide pipe 212, and the water inlet 211 and the third liquid path interface 230 can be respectively arranged at both ends of the flow guide pipe 212.

The water inlet 211 and the third liquid path interface 230 are respectively located on different sides of the base 200. For example, the water inlet 211 can be arranged on the vertical side of the base 200, and the third liquid path interface 230 can be arranged on the horizontal side of the base 200. The flow guide pipe 212 can be connected to the water inlet 211 and extend horizontally. After extending a certain distance, it can extend in the vertical direction to connect the third liquid path interface 230, connecting the water inlet 211 and the third liquid path interface 230. The flow guide pipe 212 can be bent in a variety of paths in the base 200, thereby saving installation space and facilitating the miniaturization design of the cleaning system 1000.

[0082] The wastewater formed after the external cleaning liquid flows out of the water outlet element 30 and washes the inner wall 21 can be collected in the bottom 12 of the wastewater tank 20. The bottom 12 of the wastewater tank 20 can be provided with a sewage outlet (not shown), and the wastewater can flow out of the sewage outlet (not shown) and be connected to a floor drain through the main unit 10 and / or the base 200 and discharged into the sewer.

[0083] In some embodiments, the cleaning system 1000 may further include a water pump on the flow path of the external cleaning liquid from the water inlet 211 to the sewage tank 20 to increase the cleaning water pressure in the sewage tank 20, thereby increasing the cleaning force and improving the cleaning effect.

[0084] In the cleaning system 1000 of the present embodiment, the automatic cleaning process of the sewage tank 20 is as follows: When the sewage tank 20 needs to be cleaned, the control valve 220 receives a cleaning signal and controls the water inlet 211 to open. The water inlet 211 is connected to an external water source faucet. The faucet is opened, and external cleaning liquid is introduced into the water inlet 211 and the water guide assembly 210. The external cleaning liquid passes through the guide tube 212 and reaches the third liquid circuit interface 230. The third liquid circuit interface 230 is plugged into the fourth liquid circuit interface 14. The external cleaning liquid enters the liquid channel 17 of the main unit 10 through the connection between the third liquid circuit interface 230 and the fourth liquid circuit interface 14. The external cleaning liquid passes through the liquid channel 17 and reaches the first liquid circuit interface 11. The first liquid circuit interface 11 and the second liquid circuit interface 22 are plugged into each other. The external cleaning liquid enters the water outlet element 30 through the connection between the third liquid circuit interface 230 and the fourth liquid circuit interface 14, flows out from the first water outlet 32, and sprays onto the inner wall 21 of the sewage tank 20, completing the cleaning of the inner wall 21.

[0085] In the cleaning system 1000 of the present embodiment, the sewage tank 20 can be automatically cleaned, eliminating the need for the user to open or remove the sewage tank 20 for manual cleaning. Furthermore, the water outlet element 30 surrounds the inner wall 21 of the sewage tank 20, providing a more effective cleaning effect. This effectively solves the problem of inconvenient sewage tank 20 cleaning and enhances the user experience. Furthermore, a simple structure enables fluid communication between the household tap water and the sewage tank 20, utilizing municipal water pressure pumps to deliver tap water for cleaning, making it convenient to use and further reducing costs.
