Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more specifically, to a sewage discharge component, a cleaning module, a cleaning equipment, a base station, and a cleaning system. Background Technology

[0002] After cleaning a surface, the mop attachment of a cleaning device will retain wastewater. Continuing to clean the surface with this wastewater will result in poor cleaning effectiveness. Therefore, cleaning equipment typically includes a wastewater tank to collect and recycle the wastewater from the mop attachment, thereby improving cleaning efficiency. The wastewater tank usually has a drain outlet for discharging wastewater. Currently, the drain outlet typically has a valve that opens when wastewater needs to be discharged and closes when it doesn't. However, wastewater often contains solid debris, such as hair, which can easily clog the drain channel when passing through the valve. Utility Model Content

[0003] The embodiments of this application provide a sewage discharge component, a cleaning module, a cleaning equipment, a base station, a cleaning system, and a control method for the cleaning equipment, which at least solves the problem that sewage discharge channels are easily blocked when sewage passes through valves.

[0084] The embodiments of this application are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0085] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0086] After cleaning a surface, the mop of a cleaning device will have wastewater on it. Continuing to clean the surface with wastewater on the mop will result in poor cleaning performance. Therefore, cleaning devices typically include a wastewater tank to collect and recycle the wastewater from the mop, thereby improving its cleaning effect. The wastewater tank usually has a discharge mechanism for draining the wastewater. Currently, the discharge mechanism typically has a valve inside its discharge channel, which opens when the wastewater needs to be drained and closes when it doesn't. However, wastewater often contains solid dirt, such as hair. This solid dirt can easily be scraped and blocked by the valve, causing blockage of the discharge channel. Furthermore, the valve itself may become stuck and unable to open and close properly. To address this problem, this application provides a discharge assembly 100 (… Figure 1 As shown), cleaning module ( Figure 1 (As shown), cleaning equipment 1000 ( Figure 9 As shown), base station 3000 ( Figure 10 (As shown), Cleaning System 10000 ( Figure 17 (as shown) and sewage control methods.

[0087] Please see Figure 1 and Figure 2 In a first aspect, embodiments of this application provide a sewage discharge assembly 100, which includes a sewage tank 10 and a sewage discharge component 30. The sewage tank 10 includes a tank body that forms a receiving cavity 11 for storing sewage. The sewage discharge component 30 is provided with a sewage discharge channel 31 that communicates with the receiving cavity 11 and is used to discharge sewage from the receiving cavity 11. When the external force on the outside of the sewage discharge channel 31 changes, the sewage discharge component 30 can switch between a non-discharged state and a discharged state.

[0088] Please see Figure 1 and Figure 2 Secondly, embodiments of this application provide a cleaning module 100, which includes a body 20, a mopping component, and a waste disposal component 100, with the mopping component and waste disposal component 100 disposed on the body 20.

[0089] Specifically, the cleaning module is a structure applied to the cleaning device 1000, used to clean the surface to be cleaned. The surface to be cleaned can be, but is not limited to, floors, marble surfaces, or glass surfaces. This application uses a floor as an example. The cleaning device 1000 is a device used to clean the surface to be cleaned. For example, the cleaning device 1000 may include a sweeping robot, a mopping robot, a combined sweeping and mopping robot, a handheld floor scrubber, etc. A sweeping robot can be used to sweep the surface to be cleaned, a mopping robot can be used to wipe the surface to be cleaned, a combined sweeping and mopping robot can integrate the functions of both types of robots; that is, a sweeping and mopping robot can be used to sweep the surface to be cleaned, and a sweeping and mopping robot can also be used to wipe the surface to be cleaned, and a handheld floor scrubber can be used to wipe the surface to be cleaned. Specifically, please refer to... Figure 9 The cleaning module may include a wastewater discharge component 100, which is used to discharge wastewater from the wastewater tank 10. The cleaning device 1000 of this application is illustrated using a sweeping and mopping robot as an example.

[0090] In some embodiments, the cleaning device 1000 may include a tracked cleaning robot or a roller-type cleaning robot. When the cleaning device 1000 is a tracked cleaning robot, the wiping component of the cleaning module is a tracked wiping component. When the cleaning device 1000 is a roller-type cleaning robot, the wiping component of the cleaning module is a roller-type wiping component. Both tracked and roller-type wiping components can clean the surface to be cleaned by rotating, and the cleaning device 1000 achieves a good cleaning effect on the surface. This application uses a tracked cleaning robot as an example for explanation. When the cleaning device 1000 is a tracked cleaning robot, during the process of the wiping component rotating to clean the surface, the wastewater tank 10 of the wastewater discharge component 100 can collect the dirt from the wiping component, thereby keeping the wiping component relatively clean, and the cleaning module achieves a good cleaning effect on the surface.

[0091] Please see Figure 1 and Figure 2When cleaning a mop, the cleaning module's scraper removes dirt from the mop. A wastewater tank 10 stores the dirt scraped off by the scraper to prevent it from falling onto the surface to be cleaned. In one embodiment, the wastewater tank 10 includes only a body forming a receiving cavity 11. In another embodiment, the wastewater tank 10 includes a body and may also include a lid, with the body and lid together forming the receiving cavity 11. The receiving cavity 11 stores the dirt scraped off by the scraper. The dirt may include liquid wastewater and / or solid grime. The material of the body includes, but is not limited to, metal or plastic. Metal materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys. When the body is made of metal, it has high strength and a long service life. When the body is made of plastic, the material cost is low, and the body is lightweight, making it easy to transport and handle. The cross-sectional shape of the body may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0092] The wastewater tank 10 can be installed on the main body 20 of the cleaning module, or on the body 300 of the cleaning equipment 1000. When the wastewater tank 10 is installed on the main body 20, it can be detachably or non-detachably connected to the main body 20. Detachable connections include, but are not limited to, threaded connections, screw connections, or snap-fit ​​connections, while non-detachable connections include, but are not limited to, welding, gluing, or interference fits. When the wastewater tank 10 is detachably connected to the main body 20, it can be easily removed from the main body 20 for repair in case of damage. When the wastewater tank 10 is non-detachably connected to the main body 20, the wastewater tank 10 and the main body 20 can be integrally formed, simplifying the processing steps of the wastewater discharge component 100. Similarly, when the wastewater tank 10 is installed on the body 300, it can be detachably or non-detachably connected to the body 300.

[0093] Please see Figure 1 and Figure 2 When the receiving cavity 11 is filled with dirt or the cleaning module has finished cleaning the surface to be cleaned, the cleaning device 1000 can move to the drain position to discharge the dirt from the receiving cavity 11. The drain component 30 is used to discharge the dirt from the receiving cavity 11 to the outside of the drain assembly 100. The drain channel 31 is used to supply the wastewater to flow out to the outside of the drain assembly 100, and the drain channel 31 is always in communication with the receiving cavity 11. The material of the drain component 30 can be, but is not limited to, metal or plastic. When the drain component 30 is made of metal, it has high strength, good wear resistance, and a long service life. When the drain component 30 is made of plastic, it is lighter and has a lower cost.

[0094] When the external force on the outside of the sewage discharge channel 31 changes, the sewage discharge component 30 can remain in a non-discharged state. Figure 1 (as shown) and sewage discharge status ( Figure 2 The system can switch between a non-drained state and a drained state. Components can be installed on the outside of the drain channel 31 to apply external force to the drain component 30, thus switching the drain component 30 between a drained state and a drained state. The outside of the drain channel 31 refers to all outer surfaces (including the outer side and outer end faces) of the drain component 30. In this state, no other components are needed inside the drain channel 31, allowing waste to flow smoothly out and preventing waste (such as hair) from clogging the drain channel 31 due to internal components.

[0095] The external force on the outside of the sewage channel 31 refers to the force acting on the outside of the sewage channel 31, and the source of this external force is unrestricted. The external force can be a force from a force-applying component, which can be the first force-applying component 80 of the cleaning module or the second force-applying component 3003 of the base station 3000.

[0096] The sewage discharge component 30 being in an undischarged state means that the sewage in the receiving cavity 11 cannot flow out of the sewage discharge channel 31 to the outside of the sewage discharge component 100.

[0097] When the drain component 30 is in the drain state, it means that the dirt in the receiving cavity 11 can flow out from the drain channel 31 to the outside of the drain component 100.

[0098] In this application, since the force that changes the discharge state and non-discharge state of the drain component 30 is on the outside of the drain channel 31, the drain component 30 can switch between the discharge state and the non-discharge state without any structure (such as a valve) that would affect the smoothness of the drain channel 31. This is smoother than the prior art where a valve is placed in the drain channel 31, and it is more effective in preventing the drain channel 31 from becoming blocked.

[0099] When the cleaning device 1000 is cleaning the surface to be cleaned, the dirt from the mop enters the receiving cavity 11. At this time, the drain component 30 is in an undrained state, and the dirt in the receiving cavity 11 cannot flow out through the drain channel 31, thus preventing the dirt from flowing from the drain channel 31 onto the surface to be cleaned. When the cleaning device 1000 needs to drain, the drain component 30 is in a draining state, and the dirt in the receiving cavity 11 can pass through the drain channel 31 and flow out of the drain assembly 100.

[0100] Please see Figure 1 and Figure 2In one embodiment, when the drain channel 31 is subjected to force on its outer side, the drain member 30 is in a draining state. When the drain channel 31 is not subjected to force on its outer side, the drain member 30 is in a non-draining state. When the cleaning module is cleaning the surface to be cleaned, the drain member 30 is not subjected to force and is in a non-draining state, so that the dirt in the receiving cavity 11 cannot be discharged through the drain channel 31 to the outside of the drain assembly 100. When the drain assembly 100 needs to drain, the drain member 30 is subjected to external force, and the drain member 30 switches from a non-draining state to a draining state, so that the dirt in the receiving cavity 11 can be discharged from the drain channel 31 to the outside of the drain assembly 100. In another embodiment, the external force on the drain member 30 when it is in the draining state is greater than the external force on the drain member 30 when it is in the non-draining state.

[0101] Please see Figure 7 and Figure 8 In another embodiment, when the sewage channel 31 is subjected to force on the outside (e.g. Figure 8 As shown), the drain component 30 is in an undrained state. When there is no force on the outside of the drain channel 31 (e.g.) Figure 7 As shown, the drain component 30 is in a draining state. When the cleaning module is cleaning the surface to be cleaned, the drain component 30 is under force and is in a non-draining state, so the dirt in the receiving cavity 11 cannot be discharged from the drain channel 31 to the outside of the drain assembly 100. When the drain assembly 100 needs to drain, the drain component 30 is not under force, and the drain component 30 switches from a non-draining state to a draining state, so that the dirt in the receiving cavity 11 can be discharged from the drain channel 31 to the outside of the drain assembly 100. In another embodiment, the external force on the drain component 30 when it is in a non-draining state is greater than the external force on the drain component 30 when it is in a draining state.

[0102] The sewage discharge assembly 100 of this application switches the sewage discharge member 30 between a sewage discharge state and a non-sewage discharge state by applying external force to the outside of the sewage discharge channel 31. When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge member 30 can be in the sewage discharge state, so that the sewage in the sewage tank 10 can be discharged outside the sewage discharge assembly 100. Compared with the current sewage discharge member 30, the sewage discharge member 30 of this application does not need to be equipped with a valve in the sewage discharge channel 31, so the sewage discharge channel 31 is not easy to be blocked, and the sewage flows out of the sewage discharge channel 31 more smoothly.

[0103] The sewage discharge component 100 will be further explained below with reference to the attached drawings.

[0104] Please see Figure 1 and Figure 2In some embodiments, the outlet of the sewage discharge channel 31 is a sewage outlet 311, and the height of the sewage outlet 311 can be varied when the external force changes. Specifically, in some embodiments, the sewage discharge component 30 can rotate relative to the sewage tank 10 to switch between a non-discharged state and a discharged state. When the sewage discharge component 30 is in the discharged state, the height of the sewage outlet 311 is lower than the height of the sewage outlet 311 when the sewage discharge component 30 is in the non-discharged state.

[0105] Specifically, the drain outlet 311 is used to allow wastewater in the drain channel 31 to flow out of the drain assembly 100. The drain component 30 is rotatably mounted on the body 20 of the cleaning module or the cleaning device 1000. When the external force on the outside of the drain channel 31 changes, the drain component 30 can rotate relative to the wastewater tank 10. During the rotation of the drain component 30, the height of the drain outlet 311 changes in the height direction H of the wastewater tank 10. Due to gravity, the waste in the wastewater tank 10 flows to a lower position. When the drain outlet 311 is at a lower height, the waste in the receiving cavity 11 can pass through the drain channel 31 and flow out from the drain outlet 311, thus putting the drain component 30 in a drained state. When the drain outlet 311 is at a higher height, after the waste in the receiving cavity 11 enters the drain channel 31, the waste is difficult to flow out from the drain outlet 311, thus putting the drain component 30 in a non-drained state.

[0106] When the cleaning module is cleaning the surface to be cleaned, under the action of external force, the drain component 30 can rotate relative to the sewage tank 10 to raise the height of the drain port 311, making it difficult for dirt to flow out of the drain port 311. At this time, the drain component 30 is in a non-draining state. When the drain assembly 100 needs to drain, under the action of external force, the drain component 30 can rotate relative to the sewage tank 10 to lower the height of the drain port 311, allowing dirt in the drain channel 31 to flow out of the drain port 311. At this time, the drain component 30 is in a draining state. The drain component 30 switches between the draining state and the non-draining state by rotating, and the flow of dirt from the drain channel 31 is relatively smooth, and there is no problem of blockage inside the drain channel 31.

[0107] In some embodiments, the sewage discharge channel 31 is connected to the receiving cavity 11. The sewage discharge channel 31 may be indirectly connected to the receiving cavity 11 or directly connected to the receiving cavity 11.

[0108] Please see Figures 1 to 3In some embodiments, the sewage discharge channel 31 is indirectly connected to the receiving cavity 11. The sewage discharge channel 31 also includes a sewage inlet 313, which is connected to the sewage tank 50 of the sewage discharge component 100. When the sewage discharge component 30 is not in a sewage discharge state, the sewage inlet 313 is lower than the sewage outlet 311 in the height direction H of the sewage tank 10. When the sewage discharge component 30 is in a sewage discharge state, the sewage inlet 313 is flush with the sewage outlet 311 in the height direction H of the sewage tank 10, or the sewage inlet 313 is higher than the sewage outlet 311.

[0109] The inlet 313 allows waste from the wastewater tank 50 of the sewage discharge assembly 100 to enter the discharge channel 31. The inlet 313 is located at the end where the sewage discharge component 30 connects to the wastewater tank 50 of the sewage discharge assembly 100. During the rotation of the sewage discharge component 30 relative to the wastewater tank 10, the height of the inlet 313 remains constant in the height direction H of the wastewater tank 10. The outlet 311 is located at the free end of the sewage discharge component 30, and its height varies in the height direction H of the wastewater tank 10 during the rotation of the sewage discharge component 30 relative to the wastewater tank 10.

[0110] When the cleaning module is cleaning the surface to be cleaned, under the action of external force, the drain component 30 can rotate relative to the sewage tank 10 so that the drain outlet 311 is higher than the inlet 313. After the dirt in the sewage tank 50 enters the drain channel 31 from the inlet 313, due to gravity, the dirt cannot flow to the higher drain outlet 311, so the dirt cannot flow out of the drain outlet 311 to the outside of the drain assembly 100. At this time, the drain component 30 is in an undrained state. When the drain assembly 100 needs to drain, under the action of external force, the drain component 30 can rotate relative to the sewage tank 10 so that the drain outlet 311 is lower than the inlet 313, or so that the drain outlet 311 is flush with the inlet 313. After the dirt in the sewage tank 50 enters the drain channel 31 from the inlet 313, due to gravity, the dirt can quickly flow out of the drain outlet 311 to the outside of the drain assembly 100. At this time, the drain component 30 is in a draining state.

[0111] In some embodiments, the sewage discharge component 30 is connected to the sewage tank 10 via the sewage tank 50, and the sewage discharge channel 31 is indirectly connected to the receiving cavity 11. In its natural state (i.e., without external force), the sewage discharge port 311 of the sewage discharge component 30 is higher than the sewage inlet 313 to ensure that the sewage discharge component 30 is in a non-discharged state. However, when subjected to external force on the outside of the sewage discharge channel 31, the height of the sewage discharge port 311 of the sewage discharge component 30 can be changed, making it lower than or level with the height of the sewage inlet 313 to ensure that the sewage discharge component 30 is in a discharge state. Considering practical use, since the sewage discharge component 30 is in a non-discharged state most of the time, setting the natural state of the sewage discharge component 30 to a non-discharged state, i.e., without external force applied to the sewage discharge component 30 in the non-discharged state, and only in the discharge state, external force is applied to the sewage discharge component 30, simplifies the entire control process, simplifies the structure, and improves the reliability of the sewage discharge component 100. In other embodiments, the drain component 30 is installed on the sewage tank 10, directly connected to the sewage tank 10, and the drain channel 31 is directly connected to the receiving cavity 11. In its natural state, the drain outlet 311 of the drain component 30 is higher than the highest liquid level in the height direction H of the sewage tank 10, thus the drain component is in a non-draining state. However, when subjected to external force on the outside of the drain channel 31, the height of the drain outlet 311 of the drain component 30 can be changed, making it lower than the highest liquid level in the sewage tank 10, to ensure that the drain component 30 is in a draining state. Preferably, when the drain component 30 is in a draining state, the height of the drain outlet 311 can be lower than the bottom surface of the sewage tank 10, so that all the waste in the sewage tank 10 can flow out from the drain outlet 311 to the outside of the drain assembly 100. When the drain component 10 is directly connected to the sewage tank 10, and the drain component 10 is in the draining state, the waste in the sewage tank 10 can quickly flow out from the drain channel 31 and the drain outlet. The waste in the sewage tank 10 does not need to flow through other components before entering the drain channel 31. The flow path of the waste in the sewage tank 10 into the drain channel 31 is short. When the drain component 10 is in the draining state, the waste in the sewage tank 10 can be quickly discharged outside the drain assembly 100, resulting in high efficiency in discharging waste from the sewage tank 10.

[0112] Please see Figures 1 to 3In some embodiments, the drain channel 31 is always open in both the draining and non-draining states. When the draining component 30 switches from the non-draining state to the draining state (i.e., when the draining component 30 rotates so that the drain outlet 311 is lower than the inlet 313), the waste in the receiving cavity 11 can quickly flow out of the drain channel 31 to the outside of the drain assembly 100. The drain channel 31 remains open throughout the switching between the draining and non-draining states; that is, it is always open in both states. This eliminates the need for valves or other structures in the drain channel 31, preventing hair and other debris from getting stuck and causing blockages. Furthermore, the open state of the drain channel 31 is maintained by controlling the height of the drain outlet 311 to prevent waste from flowing out of the wastewater tank 10 in the non-draining state.

[0113] The design of the drain outlet 311 varies depending on the connection method of the drain channel 31: If the drain channel 31 is directly connected to the receiving cavity 11, the height of the drain outlet 311 of the drain channel 31 is higher than the highest liquid level in the sewage tank 10 when not draining. If the drain channel 31 is connected to the sewage tank 10 through the sewage trough 50, the height of the drain outlet 311 of the drain channel 31 is higher than the sewage inlet 313 when not draining; furthermore, the height of the drain outlet 311 can be higher than the top of the sewage trough 50.

[0114] Please see Figure 2 In some embodiments, when the drain 30 is not in a draining state, the angle between the extension direction of the central axis of the drain outlet 311 toward the drain inlet 313 away from the drain 30 and the height direction from the bottom to the top of the sewage tank 10 is zero or an acute angle; when the drain 30 is in a draining state, the angle between the extension direction of the central axis of the drain outlet 311 and the height direction from the bottom to the top of the sewage tank 10 is greater than or equal to 90°.

[0115] Specifically, when the sewage discharge component 30 is not in a sewage discharge state, the angle between the central axis of the sewage discharge port 311 extending towards the sewage inlet 313 away from the sewage discharge component 30 and the height direction from the bottom to the top of the sewage tank 10 ranges from 0° to 90°. For example, the angle between the central axis of the sewage discharge port 311 extending towards the sewage inlet 313 away from the sewage discharge component 30 and the height direction from the bottom to the top of the sewage tank 10 can be 0°, 10°, 23°, 37°, 41°, 54°, 60°, 75°, 80°, or 87°, etc. In this case, in the height direction H of the sewage tank 10, the sewage discharge port 311 of the sewage discharge channel 31 is higher than the sewage inlet 313, making it difficult for sewage to flow out from the sewage discharge port 311.

[0116] When the drain outlet 30 is in the draining state, the angle between the central axis of the drain outlet 311 extending away from the drain outlet 313 and the height direction from the bottom to the top of the sewage tank 10 ranges from [90°, 180°]. For example, the angle between the central axis of the drain outlet 311 extending away from the drain outlet 313 and the height direction from the bottom to the top of the sewage tank 10 can be 90°, 108°, 112°, 126°, 133°, 145°, 160°, 173°, 80°, or 87°, etc. When the angle between the central axis of the drain outlet 311 extending away from the drain outlet 313 and the height direction from the bottom to the top of the sewage tank 10 is 90°, the drain outlet 313 and the drain outlet 311 are flush in the height direction H of the sewage tank 10. When the angle between the central axis of the drain outlet 311 extending away from the drain inlet 313 and the height direction from the bottom to the top of the sewage tank 10 is greater than 90°, the drain outlet 311 is lower than the drain inlet 313 in the height direction H of the sewage tank 10. When the drain outlet 311 is higher than the drain inlet 313 or flush with the drain inlet 313 in the height direction H of the sewage tank 10, the sewage entering the drain channel 31 from the drain inlet 313 can flow out from the drain outlet 311, so that the sewage in the sewage tank 10 can be quickly discharged outside the drain assembly 100.

[0117] Please see Figure 1 and Figure 2 In some embodiments, when the drain component 30 is subjected to an external force, the drain component 30 rotates relative to the sewage tank 10 in a first direction to switch from a non-drained state to a drained state; when the external force on the drain component 30 disappears, the drain component 30 rotates relative to the sewage tank 10 in a second direction to switch from a drained state to a non-drained state, and the first direction is opposite to the second direction.

[0118] The rotation of the sewage discharge component 30 relative to the sewage tank 10 in the first direction means that, in the height direction H of the sewage tank 10, the height of the sewage inlet 313 remains unchanged, while the height of the sewage outlet 311 gradually decreases. The rotation of the sewage discharge component 30 relative to the sewage tank 10 in the second direction means that, in the height direction H of the sewage tank 10, the height of the sewage inlet 313 remains unchanged, while the height of the sewage outlet 311 gradually increases.

[0119] When the sewage discharge assembly 100 needs to discharge sewage, the side wall of the sewage discharge member 30 can be subjected to external force, thereby allowing the sewage discharge member 30 to rotate in a first direction. When the sewage discharge member 30 rotates in the first direction, the height of the sewage outlet 311 gradually decreases in the height direction H of the sewage tank 10. When the angle between the extension direction of the central axis of the sewage outlet 311 and the height direction from the bottom to the top of the sewage tank 10 is within the range of [90°, 180°], that is, in the height direction H of the sewage tank 10, the sewage outlet 311 is lower than the sewage inlet 313, or the sewage outlet 311 is flush with the sewage inlet 313, so that the sewage entering the sewage discharge channel 31 from the sewage inlet 313 can flow out from the sewage outlet 311, at which point the sewage discharge member 30 is in a sewage discharge state. When the sewage discharge member 30 is in a sewage discharge state, the sewage in the sewage tank 10 can be quickly discharged from the sewage discharge channel 31 to the outside of the sewage discharge assembly 100.

[0120] When the sewage discharge assembly 100 has completed its discharge, the external force on the side wall of the sewage discharge member 30 disappears, allowing the sewage discharge member 30 to rotate in the second direction. As the sewage discharge member 30 rotates in the second direction, the height of the sewage outlet 311 gradually increases in the height direction H of the sewage tank 10. When the angle between the extension direction of the central axis of the sewage outlet 311 and the height direction from the bottom to the top of the sewage tank 10 is within the range of [0°, 90°], that is, in the height direction H of the sewage tank 10, the sewage outlet 311 is higher than the sewage inlet 313, making it difficult for dirt entering the sewage discharge channel 31 from the sewage inlet 313 to flow out of the sewage outlet 311. At this time, the sewage discharge member 30 is in a non-discharged state. When the sewage discharge member 30 is in a non-discharged state, dirt in the sewage tank 10 will not flow to the surface to be cleaned.

[0121] Please see Figure 2 In some embodiments, the sewage discharge component 30 includes a force-bearing part 33, which is located outside the sewage discharge channel 31 in the radial direction. Specifically, in some embodiments, the force-bearing part 33 is provided with a mating surface 331. When the mating surface 331 is not subjected to external force, the sewage discharge component 30 is in a non-discharged state; when the mating surface 331 is subjected to external force, the sewage discharge component 30 rotates relative to the sewage tank 10 in a first direction to switch from a non-discharged state to a discharged state.

[0122] Specifically, the drain component 30 includes a main body and a force-receiving part 33. The force-receiving part 33 is used to cooperate with other components to receive the force applied to the drain component 30 by those components. When the force applied to the mating surface 331 of the force-receiving part 33 by other components changes, the force-receiving part 33 can drive the main body to rotate in a first direction and a second direction. The force-receiving part 33 can be located at any position on the side wall of the main body. The force-receiving part 33 and the main body can be an integral structure or separate structures. When the force-receiving part 33 and the main body are an integral structure, they can be integrally formed. When the force-receiving part 33 and the main body are separate structures, they can be detachably or non-detachably connected.

[0123] When the sewage discharge assembly 100 needs to discharge sewage, the mating surface 331 is subjected to force, thereby causing the force-bearing part 33 to rotate in the first direction, and the sewage discharge component 30 can rotate relative to the sewage tank 10 in the first direction. In the height direction H of the sewage tank 10, the height of the sewage outlet 311 gradually decreases, thereby switching the sewage discharge component 30 from a non-discharging state to a discharging state. When the sewage discharge assembly 100 completes sewage discharge or the cleaning module cleans the surface to be cleaned, the external force on the mating surface 331 disappears, thereby causing the force-bearing part 33 to rotate in the second direction, and the sewage discharge component 30 can rotate relative to the sewage tank 10 in the second direction. In the height direction H of the sewage tank 10, the height of the sewage outlet 311 gradually increases, thereby switching the sewage discharge component 30 from a discharging state to a non-discharging state.

[0124] Please see Figure 2 In some embodiments, the external force on the mating surface 331 is a contact-type tensile or compressive force. When the sewage discharge assembly 100 needs to discharge sewage, the mating surface 331 is used to contact other components. In the height direction H of the sewage tank 10, if the component applying force to the mating surface 331 is lower than the sewage discharge member 30, other components can apply tensile force to the mating surface 331 to cause the sewage discharge member 30 to rotate in a first direction, thereby allowing the sewage discharge member 30 to switch from a non-discharge state to a discharge state, and the sewage in the sewage tank 10 can be discharged from the sewage discharge channel 31. In the height direction H of the sewage tank 10, if the component applying force to the mating surface 331 is higher than the sewage discharge member 30, other components can apply compressive force to the mating surface 331 to cause the sewage discharge member 30 to rotate in a first direction, thereby allowing the sewage discharge member 30 to switch from a non-discharge state to a discharge state, and the sewage in the sewage tank 10 can be discharged from the sewage discharge channel 31. When the external force on the mating surface 331 is a contact-type tensile or compressive force, the force on the drain component 30 is relatively stable, which can avoid the problem that the drain component 30 cannot rotate in the first direction when the drain assembly 100 needs to drain (for example, the magnetism weakens and the magnetic attraction disappears).

[0125] Please see Figure 2In other embodiments, the external force on the mating surface 331 is a non-contact repulsive or attractive force. Preferably, the external force on the mating surface 331 can be a magnetic repulsive or attractive force. In one example, the mating surface 331 may be provided with a first magnetic attractor, and the sewage discharge assembly 100 may also include a second magnetic attractor, with the first and second magnetic attractors repelling each other. When the sewage discharge assembly 100 needs to discharge sewage, the second magnetic attractor may be higher than the sewage discharge member 30 in the height direction H of the sewage tank 10. The first magnetic attractor and the second magnetic attractor repel each other, and the sewage discharge member 30 is subjected to the repulsive force of the second magnetic attractor, so that the sewage discharge member 30 can rotate in the first direction, and the sewage discharge member 30 can switch from a non-discharged state to a discharged state, and the sewage in the sewage tank 10 can be discharged from the sewage discharge channel 31. When all the sewage in the sewage tank 10 has been discharged, the sewage discharge member 30 needs to switch from the discharged state to a non-discharged state. Exemplarily, the first magnetic attractor and the second magnetic attractor may both be electromagnets. When the discharge component 30 needs to switch from a non-discharge state to a discharge state, both the first and second magnetic components are energized, causing them to repel each other. The discharge component 30 can then rotate in the first direction, switching from a non-discharge state to a discharge state. When all the waste in the sewage tank 10 has been discharged, the first and / or second magnetic components are de-energized, the repulsive force disappears, and the discharge component 30 can rotate in the second direction, switching from a discharge state to a non-discharge state. The first and second magnetic components can also be ordinary magnets; in this case, the position of the second magnetic component can move relative to the first magnetic component. When the discharge component 30 needs to switch from a non-discharge state to a discharge state, the second magnetic component moves to a position where it can generate a repulsive force with the first magnetic component, allowing the discharge component 30 to rotate in the first direction, switching from a non-discharge state to a discharge state. When all the waste in the sewage tank 10 is discharged, the second magnetic attractor can move away from the first magnetic attractor, the repulsive force between the first and second magnetic attractors disappears, and the sewage discharge device 30 can rotate in the second direction, and the sewage discharge device 30 can switch from the sewage discharge state to the non-sewage discharge state.

[0126] In another example, the mating surface 331 may be provided with a first magnetic attractor, and the sewage discharge assembly 100 may also include a second magnetic attractor, with the first and second magnetic attractors attracting each other. When the sewage discharge assembly 100 needs to discharge sewage, the second magnetic attractor may be lower than the sewage discharge member 30 in the height direction H of the sewage tank 10. The first magnetic attractor and the second magnetic attractor attract each other, and the sewage discharge member 30 is subjected to the attraction force of the second magnetic attractor, so that the sewage discharge member 30 can rotate in the first direction, and the sewage discharge member 30 can switch from a non-discharge state to a discharge state, and the sewage in the sewage tank 10 can be discharged from the sewage discharge channel 31. For example, the first magnetic attractor and the second magnetic attractor may both be electromagnets. When the sewage discharge member 30 needs to switch from a non-discharge state to a discharge state, both the first magnetic attractor and the second magnetic attractor are energized, so that the first magnetic attractor and the second magnetic attractor attract each other, the sewage discharge member 30 can rotate in the first direction, and the sewage discharge member 30 can switch from a non-discharge state to a discharge state. When all the waste in the sewage tank 10 has been discharged, the first and / or second magnetic components are de-energized, the attraction disappears, and the discharge component 30 can rotate in the second direction, switching from a discharge state to a non-discharge state. The first and second magnetic components can also be ordinary magnets; in this case, the position of the second magnetic component can move relative to the first magnetic component. When the discharge component 30 needs to switch from a non-discharge state to a discharge state, the second magnetic component moves to a position where it can generate attraction with the first magnetic component, allowing the discharge component 30 to rotate in the first direction, switching from a non-discharge state to a discharge state. When all the waste in the sewage tank 10 has been discharged, the second magnetic component can move away from the first magnetic component, the attraction between the first and second magnetic components disappears, allowing the discharge component 30 to rotate in the second direction, switching from a discharge state to a non-discharge state.

[0127] In another example, the mating surface 331 may be provided with a first magnetic attractor, and the base station 3000 may be provided with a second magnetic attractor. After the cleaning device 1000 enters the base station 3000, the first and second magnetic attractors attract or repel each other, thereby allowing the discharge device 30 to rotate along a first direction, and the discharge device 30 can switch from a discharge state to a non-discharge state. After the cleaning device 1000 enters the base station 3000, the attraction or repulsion between the first and second magnetic attractors disappears, thereby allowing the discharge device 30 to rotate along a second direction, and the discharge device 30 can switch from a discharge state to a non-discharge state.

[0128] When the external force on the mating surface 331 is a non-contact repulsive or attractive force, the mating surface 331 does not need to contact other components, thus the wear on the mating surface 331 is small, and the service life of the drain component 30 is long. Moreover, when the mating surface 331 is subjected to repulsive or attractive forces, the drain component 30 can quickly rotate along the first direction, and the drain component 30 can switch from a non-drainage state to a drainage state at a relatively fast speed.

[0129] Please see Figure 2 and Figure 3 Furthermore, in some embodiments, the sewage discharge assembly 100 also includes a reset member 40. One end of the reset member 40 is connected to the sewage tank 50 of the sewage discharge assembly 100 or the body 20 of the cleaning module, and the other end is connected to the sewage discharge member 30. When the external force on the sewage discharge member 30 disappears, the reset member 40 drives the sewage discharge member 30 to rotate in the second direction to switch from the sewage discharge state to the non-sewage discharge state.

[0130] Because, in its natural state, the height of the drain outlet 311 is higher than the height of the inlet 313, or the height of the drain outlet 311 is higher than the highest liquid level in the sewage tank 10, the sewage in the sewage tank 10 cannot flow out of the drain outlet 311 when the drain component 30 is in its natural state, and the drain component 30 is in a non-drained state. When the external force on the drain component 30 disappears, the reset component 30 is used to drive the drain component 30 back to its natural state, so that the drain component 30 can quickly switch to the non-drained state.

[0131] When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge component 30 is subjected to an external force, allowing it to rotate in a first direction, thus switching from a non-discharge state to a discharge state. During the sewage discharge process of the sewage discharge assembly 100, the sewage discharge component 30 is continuously subjected to an external force to maintain it in the discharge state. Once all the sewage in the sewage tank 10 has been discharged outside the sewage discharge assembly 100, the external force on the sewage discharge component 30 disappears, and the reset component 40 can move the sewage discharge component 30 back to the non-discharge state.

[0132] In one embodiment, the reset member 40 may be a torsion spring. When the drain member 30 is in an undrained state, the torsion spring is in its natural state. When the drain member 30 is rotated in a first direction by an external force to enter a draining state, the torsion spring is compressed. Due to the elastic potential energy of the torsion spring, it tends to cause the drain member 30 to rotate in a second direction. Thus, when the external force on the drain member 30 disappears, the torsion spring can drive the drain member 30 to rotate in the second direction, switching the drain member 30 from a draining state to an undrained state, and the torsion spring returns to its natural state.

[0133] When the drain assembly 100 includes a reset member 40, the reset member 40 can automatically return the drain member 30 to the non-drained state when the drain member 30 is not subjected to external force. During the rotation of the drain member 30 in the second direction, there is no need to set up other components to apply external force to the drain member 30. The way the drain member 30 rotates in the second direction is relatively simple, and the drain member 30 switches from the drained state to the non-drained state quickly.

[0134] Please see Figure 1 and Figure 2In some embodiments, the sewage discharge assembly 100 further includes a sewage tank 50 and a connecting pipe 60. The sewage discharge component 30 is installed in the sewage tank 50, and the sewage discharge channel 31 communicates with the sewage tank 50. One end of the connecting pipe 60 communicates with the sewage tank 10, and the other end communicates with the sewage tank 50.

[0135] Specifically, the sewage tank 50 is used to collect waste, and the connecting pipe 60 connects the sewage tank 50 and the receiving cavity 11. Waste in the sewage tank 50 can enter the receiving cavity 11 through the connecting pipe 60, and waste in the receiving cavity 11 can also enter the sewage tank 50 through the connecting pipe 60. The material of the connecting pipe 60 can be, but is not limited to, metal or plastic. When the connecting pipe 60 is made of metal, it has high strength, good wear resistance, and a long service life. When the connecting pipe 60 is made of plastic, it is lighter and less expensive.

[0136] The receiving cavity 11, connecting pipe 60, sewage tank 50, and sewage discharge channel 31 are connected in sequence. When the cleaning module is cleaning the surface to be cleaned, the dirt scraped off by the cleaning module's scraping component enters the sewage tank 50, and the dirt enters the receiving cavity 11 through the connecting pipe 60 and is stored in the receiving cavity 11. At this time, the sewage discharge component 30 is in an undischarged state. In the height direction H of the sewage tank 10, the sewage discharge port 311 is higher than the sewage inlet 313, so the dirt in the receiving cavity 11 will not flow out from the sewage discharge port 311 to the surface to be cleaned.

[0137] When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge component 30 rotates in the first direction under the action of external force, switching from a non-discharge state to a discharge state. In the height direction H of the sewage tank 10, the sewage discharge port 311 is lower than the sewage inlet 313, or the sewage discharge port 311 is flush with the sewage inlet 313. The sewage in the receiving cavity 11 can flow through the connecting pipe 60, the sewage tank 50 and the sewage discharge channel 31, and flow out from the sewage discharge port 311 to the outside of the sewage discharge assembly 100. Preferably, the sewage tank 50 and the sewage discharge component 30 are sealed together, so that during the process of sewage in the sewage tank 50 flowing into the sewage discharge channel 31, sewage can be prevented from flowing out from the gap between the sewage tank 50 and the sewage discharge component 30.

[0138] During the cleaning process of the wastewater tank 10, when the cleaning liquid enters and soaks the wastewater tank 10, the drain component 30 is in a non-draining state. When the cleaning liquid in the wastewater tank 10 needs to be drained, the drain component 30 rotates in the first direction under the action of external force, and the drain component 30 switches from the non-draining state to the draining state. The cleaning liquid in the receiving cavity 11 can carry the dirt through the connecting pipe 60 and the wastewater tank 50, and be discharged from the drain channel 31.

[0139] Please see Figures 1 to 3In some embodiments, the connecting pipe 60 includes a first opening and a second opening opposite to each other. The first opening is connected to the sewage tank 10, and the second opening and the inlet 313 of the drain component 30 are respectively connected to opposite ends of the sewage tank 50. When waste in the receiving cavity 11 needs to be discharged, the waste flowing out of the receiving cavity 11 enters the connecting pipe 60 through the first opening and flows into the sewage tank 50 through the second opening of the connecting pipe 60. Due to the fluidity of the waste, it spreads and flows into various locations in the sewage tank 50. When the second opening and the inlet 313 of the drain component 30 are located at opposite ends of the sewage tank 50, the waste entering the sewage tank 50 from the second opening of the connecting pipe 60 tends to flow towards the drain component 30. Almost all the waste in the sewage tank 50 can flow into the drain channel 31 and flow out from the drain outlet 311 to the outside of the drain assembly 100.

[0140] When the cleaning liquid in the receiving cavity 11 needs to be drained, the cleaning liquid in the receiving cavity 11 enters the connecting pipe 60 through the first opening. The cleaning liquid can flow through various positions of the connecting pipe 60, carrying the dirt in the connecting pipe 60 into the sewage tank 50 through the second opening. When the second opening and the sewage inlet 313 are respectively connected to the opposite ends of the sewage tank 50, the cleaning liquid entering the sewage tank 50 through the second opening of the connecting pipe 60 can flow through various positions in the sewage tank 50. The cleaning liquid can carry the dirt in the sewage tank 50 through the sewage inlet 313 and flow out through the drain channel 31, thus the cleaning liquid has a better cleaning effect on the connecting pipe 60 and the sewage tank 50.

[0141] Please see Figure 1 and Figure 2 Furthermore, in some embodiments, the sewage discharge assembly 100 further includes a drive member 70 connected to the sewage discharge assembly 30, and the drive member 70 is used to drive the sewage discharge assembly 30 to rotate to switch between a non-discharged state and a discharged state.

[0142] Specifically, when the cleaning module is cleaning the surface to be cleaned, the drive unit 70 drives the draining unit 30 to rotate in the second direction, so that the draining unit 30 switches from a draining state to a non-draining state. When the draining assembly 100 needs to drain, the drive unit 70 drives the draining unit 30 to rotate in the first direction, so that the draining unit 30 switches from a non-draining state to a draining state.

[0143] Please see Figure 1 and Figure 2 In some embodiments, the cleaning module further includes a position detection unit and a processing unit. The position detection unit is used to detect the position of the cleaning module relative to the body 300 of the cleaning equipment 1000. The processing unit is used to determine whether the position of the cleaning module relative to the body 300 meets predetermined conditions based on the detection information from the position detection unit, and to control the operation of the drive unit 70 based on the determination result.

[0144] Specifically, in some embodiments, the cleaning module can be moved relative to the body 300 of the cleaning device 1000 to a first relative position and a second relative position. When the cleaning module is in the second relative position, the maximum outline width of the cleaning module is greater than that when the cleaning module is in the first relative position. When the cleaning module moves from the first relative position to the second relative position, the processing unit controls the drive 70 to drive the discharge component 30 to rotate relative to the sewage tank 10 in a first direction to switch from a non-discharged state to a discharged state. When the cleaning module moves from the second relative position to the first relative position, the processing unit controls the drive 70 to drive the discharge component 30 to rotate relative to the sewage tank 10 in a second direction to switch from a discharged state to a non-discharged state. The first direction is opposite to the second direction.

[0145] In the first relative position, the cleaning module can be located below the body 300 of the cleaning device 1000, and the horizontal projection of the body 300 of the cleaning device 1000 can cover the horizontal projection of the cleaning module. In the second relative position, one end of the cleaning module can protrude from one side of the body 300 of the cleaning device 1000. The position of the cleaning module relative to the body 300 satisfies the predetermined condition when the cleaning module is in either the first relative position or the second relative position relative to the body 300 of the cleaning device 1000.

[0146] When the sewage discharge assembly 100 needs to discharge sewage, the cleaning module can move to a second relative position relative to the body 300 of the cleaning equipment 1000. When the position detection unit detects that the cleaning module is in the second relative position relative to the body 300 of the cleaning equipment 1000, it transmits this detection information to the processing unit. The position detection unit is communicatively connected to the processing unit. When the processing unit determines that the cleaning module has reached the second relative position, it controls the drive unit 70 to drive the sewage discharge assembly 30 to rotate relative to the sewage tank 10 in a first direction, thereby switching the sewage discharge assembly 30 from a non-discharge state to a discharge state.

[0147] When the cleaning module is cleaning the surface to be cleaned, the cleaning module can move to a first relative position relative to the body 300 of the cleaning equipment 1000. When the position detection unit detects that the cleaning module is in the first relative position relative to the body 300 of the cleaning equipment 1000, it transmits this detection information to the processing unit. Once the processing unit determines that the cleaning module has reached the first relative position, it controls the drive unit 70 to drive the discharge unit 30 to rotate relative to the wastewater tank 10 in a second direction, thereby switching from a discharge state to a non-discharge state.

[0148] The position detection unit is communicatively connected to the processing unit, which in turn is communicatively connected to the drive unit 70. By detecting the relative position of the cleaning module to the body 300 of the cleaning equipment 1000 through the position detection unit, the processing unit can control the drive unit 70 to switch the drain component 30 between a non-draining state and a draining state. When draining is required, the drain component 30 automatically switches to the draining state by rotating. The entire process requires no manual intervention, resulting in high efficiency and a good user experience.

[0149] When the drain component is made of rigid material, it needs to rotate relative to the sewage tank or trough to switch between a non-drained and drained state. After a certain period of use, the connection between the drain component and the sewage tank or trough may wear down. Wear at this connection creates a gap between the drain component and the tank or trough, potentially affecting the seal. As waste flows from the tank or trough to the drain channel, some of it may leak through this gap and onto the surface to be cleaned, causing secondary contamination.

[0150] Please see Figures 3 to 6 In the embodiments of this application, the sewage discharge component 30 includes a first sub-part 35 and a second sub-part 37. The first sub-part 35 is sleeved on the second sub-part 37. The force-bearing part 33 of the sewage discharge component 30 is provided on the side wall of the first sub-part 35. The sewage discharge channel 31 is provided on the second sub-part 37. The first sub-part 35 is a rigid pipe and the second sub-part 37 is a flexible pipe.

[0151] In one embodiment, the second sub-part 37 is sealed to the sewage tank 50. Specifically, the first sub-part 35 is used to rotate relative to the sewage tank 10 under external force, and the first sub-part 35 can drive the second sub-part 37 to rotate together, so that the sewage discharge component 30 can switch between a non-discharged state and a discharged state. The second sub-part 37 is used to connect to the sewage tank 50, so that the sewage in the sewage tank 50 can flow out from the sewage discharge channel 31 of the second sub-part 37 to the outside of the sewage discharge assembly 100. Since the second sub-part 37 is a flexible hose, the connection between the second sub-part 37 and the sewage tank 50 is not easily worn during the rotation of the second sub-part 37, which can ensure good sealing at the connection between the second sub-part 37 and the sewage tank 50, thereby avoiding the problem of sewage flowing out from the gap between the sewage tank 50 and the second sub-part 37.

[0152] In another embodiment, the second sub-part 37 is sealed to the sewage tank 10. Specifically, the first sub-part 35 is used to rotate relative to the sewage tank 10 under external force, and the first sub-part 35 can drive the second sub-part 37 to rotate together, so that the sewage discharge component 30 can switch between a non-discharged state and a discharged state. The second sub-part 37 is used to connect to the sewage tank 10, so that the sewage in the sewage tank 10 can flow out from the sewage discharge channel 31 of the second sub-part 37 to the outside of the sewage discharge assembly 100. Since the second sub-part 37 is a flexible hose, the connection between the second sub-part 37 and the sewage tank 10 is not easily worn during the rotation of the second sub-part 37, which can ensure good sealing at the connection between the second sub-part 37 and the sewage tank 10, thereby avoiding the problem of sewage flowing out from the gap between the sewage tank 10 and the second sub-part 37.

[0153] When the first sub-part 35 is a rigid tube, it is not easily deformed under external force, allowing it to rotate and drive the second sub-part 37 to rotate. The first sub-part 35 and the second sub-part 37 rotate together, allowing the drain component 30 to switch between a non-drained state and a drained state. The material of the first sub-part 35 can be, but is not limited to, metal or plastic. When the first sub-part 35 is made of metal, it has higher strength, is less prone to deformation under external force, and has a longer lifespan. When the first sub-part 35 is made of plastic, it is lighter and has a lower cost. When the second sub-part 37 is a flexible hose, the sealing effect between the second sub-part 37 and the sewage tank 50 is better. Furthermore, during rotation, the flexibility of the second sub-part 37 allows it to buffer the tensile force at the connection point with the sewage tank 50 when rotated by the first sub-part 35. This reduces wear between the second sub-part 37 and the sewage tank 50, minimizing the gap between them and reducing the likelihood of waste leaking out through the gap between the side wall of the sewage tank 50 and the second sub-part 37. The material of the second sub-part 37 can be, but is not limited to, rubber, silicone, or polyethylene.

[0154] Please see Figures 3 to 6 Furthermore, in some embodiments, the side wall of the first sub-part 35 is provided with a rotating shaft 351, which can rotate relative to the sewage tank 10. During the rotation of the first sub-part 35 relative to the main body 20 along a first direction and a second direction, the rotating shaft 351 also rotates relative to the main body 20. The connection between the rotating shaft 351 and the main body 20 provides a certain supporting force to the first sub-part 35, thereby making the first sub-part 35 more stable during rotation along the first and second directions.

[0155] Please see Figure 3 and Figure 5 In some embodiments, a first gap 38 is provided between the first sub-part 35 and the second sub-part 37. In this case, during the rotation of the second sub-part 37 by the first sub-part 35, the friction between the first sub-part 35 and the second sub-part 37 is minimal, thereby preventing mutual wear between them. The first sub-part 35 and the second sub-part 37 are less prone to damage and have a longer service life.

[0156] Please see Figure 3 and Figure 5 In some embodiments, the first sub-part 35 includes a first end 353 and a second end 355 opposite to each other, the first end 353 of the first sub-part 35 being closer to the sewage tank 50 than the second end 355 of the first sub-part 35; the second sub-part 37 includes a first end 371 and a second end 373 opposite to each other, the first end 371 of the second sub-part 37 being closer to the sewage tank 50 than the second end 373 of the second sub-part 37; the first end 371 of the second sub-part 37 is closer to the sewage tank 50 than the first end 353 of the first sub-part 35, and the first end 371 of the second sub-part 37 is sealed to the sewage tank 50.

[0157] The inlet 313 is located at the first end 371 of the second sub-part 37, and the outlet 311 is located at the second end 373 of the second sub-part 37. The first end 353 of the first sub-part 35 is connected to the side wall of the sewage tank 50, and the second end 355 of the first sub-part 35 is close to the outlet 311. When the first end 371 of the second sub-part 37 is closer to the sewage tank 50 than the first end 353 of the first sub-part 35, that is, the first end 371 of the second sub-part 37 protrudes relative to the first end 353 of the first sub-part 35. Because the first end 371 of the second sub-part 37 is sealed to the sewage tank 50, sewage in the sewage tank 50 is prevented from flowing into the first gap 38, and sewage is also prevented from flowing out from the side wall of the sewage tank 50 and the second end 373 of the second sub-part 37. All sewage in the sewage tank 50 enters the sewage discharge channel 31 from the inlet 313 of the first end 371 of the second sub-part 37 and is discharged from the outlet 311.

[0158] In other embodiments, the first sub-part 35 includes a first end 353 and a second end 355 opposite to each other, the first end 353 of the first sub-part 35 being closer to the receiving cavity 11 than the second end 355 of the first sub-part 35; the second sub-part 37 includes a first end 371 and a second end 373 opposite to each other, the first end 371 of the second sub-part 37 being closer to the receiving cavity 11 than the second end 373 of the second sub-part 37; the first end 371 of the second sub-part 37 is closer to the receiving cavity 11 than the first end 353 of the first sub-part 35, and the first end 371 of the second sub-part 37 is sealed to the sewage tank 10.

[0159] At this time, the first end 353 of the first sub-part 35 is connected to the side wall of the sewage tank 10, and the second end 355 of the first sub-part 35 is close to the drain port 311. When the first end 371 of the second sub-part 37 is closer to the receiving cavity 11 than the first end 353 of the first sub-part 35, that is, the first end 371 of the second sub-part 37 protrudes relative to the first end 353 of the first sub-part 35. Since the first end 371 of the second sub-part 37 is sealed to the sewage tank 10, sewage in the sewage tank 10 is prevented from flowing into the first gap 38, and sewage is also prevented from flowing out from between the side wall of the sewage tank 10 and the second end 373 of the second sub-part 37. All sewage in the sewage tank 10 enters the drain channel 31 from the inlet 313 of the first end 371 of the second sub-part 37 and is discharged from the drain port 311.

[0160] Please see Figure 3 and Figure 4 In some embodiments, the second end 373 of the second sub-part 37 is flush with the second end 355 of the first sub-part 35. In this case, when waste flows out of the drain outlet 31 from the drain channel 31, the probability of waste flowing into the first gap 38 from the second end 373 of the second sub-part 37 is reduced. In other embodiments, the second end 373 of the second sub-part 37 extends beyond the second end 355 of the first sub-part 35. In this case, when waste flows out of the drain outlet 311 from the drain channel 31, the probability of waste flowing into the first gap 38 from the second end 373 of the second sub-part 37 is further reduced.

[0161] Please see Figure 5 and Figure 6 Furthermore, in some embodiments, the second end 373 of the second sub-part 37 extends beyond the second end 355 of the first sub-part 35 and covers the second end 355 of the first sub-part 35. The gap between the second end 373 of the second sub-part 37 and the second end 355 of the first sub-part 35 can be covered by the bend 375 of the second sub-part 37, so that all the dirt flowing out from the second end 373 of the second sub-part 37 can be discharged outside the drain assembly 100, and the dirt will not flow into the first gap 38 from the second end 373 of the second sub-part 37.

[0162] Please see Figure 5 and Figure 6 Furthermore, in some embodiments, a second gap 39 is provided between the bend 375 of the second end 373 of the second sub-part 37 and the second end 355 of the first sub-part 35.

[0163] During the rotation of the second sub-part 37 driven by the first sub-part 35, the connection between the sewage tank 50 and the first end 371 of the second sub-part 37 exerts a certain pulling force on the second sub-part 37. When there is no gap between the bent portion 375 of the second end 373 of the second sub-part 37 and the second end 355 of the first sub-part 35, the second sub-part 37 is easily damaged when pulled at the connection between the sewage tank 50 and the first end 371. In this embodiment, a second gap 39 is provided between the bent portion 375 and the second end 355 of the first sub-part 35. When the second sub-part 37 is pulled at the connection between the sewage tank 50 and the first end 371, the second gap 39 provides a certain deformation space for the second sub-part 37, thus making it less prone to damage and improving its service life.

[0164] Please see Figure 7 and Figure 8 In some embodiments, the drain component 30 can be deformed under external force on the outside of the drain channel 31 to switch between a non-drainage state and a drainage state. When the drain component 30 is in the drainage state, the drain channel 31 is in the conducting state, and when the drain component 30 is in the non-drainage state, the drain channel 31 is in the closed state.

[0165] Specifically, please combine Figure 1 and Figure 2 When the drain component 30 is deformable under external force, it can be a flexible hose, and its material can be, but is not limited to, rubber, silicone, or polyethylene. The drain channel 31 being in a conductive state means that waste flowing into the drain channel 31 from the sewage tank 50 can flow out from the drain outlet 311 to the outside of the drain assembly 100. In this case, the minimum cross-sectional area of ​​the drain channel 31 only needs to be greater than 0. In one example, when the drain channel 31 is in a conductive state, the drain component 30 is not subjected to external force and is in a natural state. In this case, the cross-sectional area of ​​the drain channel 31 is equal at all locations, and the cross-sectional area of ​​the drain channel 31 is relatively large, allowing waste flowing into the drain channel 31 from the sewage tank 50 to be quickly discharged to the outside of the drain assembly 100. In another example, when the drain channel 31 is in a conductive state, the drain component 30 is subject to external force and is in a partially deformed state; the minimum cross-sectional area of ​​the drain channel 31 is greater than 0. The sewage discharge channel 31 being in the closed state means that the sewage flowing into the sewage discharge channel 31 from the sewage tank 50 cannot flow out of the sewage outlet 311 to the outside of the sewage discharge assembly 100. At this time, the minimum cross-sectional area of ​​the sewage discharge channel 31 is 0. When the sewage discharge channel 31 is in the closed state, the side wall of the sewage discharge component 30 is subjected to external force, and the sewage discharge component 30 is in a fully deformed state.

[0166] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 In some embodiments, when the drain component 30 is in the draining state, the height of the drain outlet 311 relative to the sewage tank 10 is the same as the height of the drain outlet 311 relative to the sewage tank 10 when the drain component 30 is in the non-draining state. That is, during the switching between the non-draining state and the draining state, the height of the drain outlet 311 relative to the sewage tank 10 remains unchanged. At this time, in the height direction H of the sewage tank 10, the height of the drain outlet 311 relative to the height of the inlet 313 remains unchanged; the drain outlet 311 is flush with the inlet 313 or lower than the inlet 313. The overall position of the drain component 30 relative to the sewage tank 10 remains unchanged.

[0167] When the cleaning module is cleaning the surface to be cleaned, the drain component 30 is subjected to external force and deforms, thereby closing the drain channel 31 and preventing the dirt in the receiving cavity 11 from being discharged from the drain port 311 to the outside of the drain assembly 100. When the drain assembly 100 needs to be drained, the drain component 30 may be unaffected by external force or subjected to a small external force, and the drain component 30 may be in a natural state or a state of slight deformation, thereby opening the drain channel 31 and allowing the dirt in the receiving cavity 11 to be discharged from the drain port 311 to the outside of the drain assembly 100.

[0168] When the drain component 30 switches from a non-draining state to a draining state, it is only necessary to remove or reduce the external force applied to the drain component 30, making the switching process relatively simple. When the external force on the drain component 30 decreases or disappears, the waste in the sewage tank 50 can flow out of the drain channel 31 to the outside of the drain assembly 100, and the waste in the receiving cavity 11 is discharged from the drain channel 31 at a relatively fast speed.

[0169] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 In some embodiments, the cleaning module further includes a first force-applying member 80, which is used to apply an external force to the drain member 30 to make the drain channel 31 either open or closed. Specifically, in some embodiments, when the first force-applying member 80 applies an external force to the side wall of the drain member 30, the drain channel 31 is in a closed state; when the external force applied by the first force-applying member 80 to the drain member 30 disappears, the drain channel 31 is in a connected state.

[0170] Specifically, the first force-applying member 80 can be disposed on the body 20. The first force-applying member 80 applies an external force to the sewage discharge member 30, thereby deforming the sewage discharge member 30. When the external force applied to the sewage discharge member 30 by the first force-applying member 80 disappears, the sewage discharge member 30 can return to its natural state. When the sewage discharge channel 31 is closed, the first force-applying member 80 is in contact with the sewage discharge member 30. When the sewage discharge channel 31 is open, the first force-applying member 80 can be spaced apart from the sewage discharge member 30.

[0171] During the cleaning process of the cleaning module, the first force-applying component 80 applies external force to the side wall of the drain component 30, causing the drain component 30 to deform. This closes the drain channel 31, and the drain component 30 is in a non-drained state, preventing dirt from being discharged from the drain port 311 in the receiving cavity 11. This avoids the problem of dirt flowing onto the surface to be cleaned. When the drain component 100 needs to drain, the first force-applying component 80 removes the external force on the drain component 30, leaving the drain component 30 in a natural state. This opens the drain channel 31, and the drain component 30 is in a non-drained state, allowing dirt to flow out from the drain port 311. At this time, the cross-sectional area of ​​the drain channel 31 is large, allowing dirt to flow out quickly.

[0172] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 Furthermore, in some embodiments, the cleaning module also includes a drive unit connected to the first force-applying member 80, which is used to drive the first force-applying member 80 to apply external force to or remove the applied external force from the sewage discharge member 30.

[0173] When the cleaning module is cleaning the surface to be cleaned, the drive unit drives the first force-applying member 80 to apply external force to the side wall of the drain member 30, causing the drain member 30 to deform and the drain channel 31 to be closed. Dirt cannot be discharged from the drain port 311, thus preventing dirt from flowing onto the surface to be cleaned. When the drain assembly 100 needs to drain, the drive unit drives the first force-applying member 80 to remove the external force on the drain member 30, so the drain member 30 is no longer subject to external force, returns to its natural state, and the drain channel 31 is open, allowing dirt to flow out from the drain port 311.

[0174] The drive unit can communicate with the processing unit. The processing unit determines whether the position of the cleaning module relative to the body 300 of the cleaning device 1000 meets predetermined conditions based on the detection information from the position detection unit, and controls the operation of the drive unit based on the determination result. When the drain assembly 100 needs to drain, the cleaning module can move to a second relative position relative to the body 300 of the cleaning device 1000. When the position detection unit detects that the cleaning module is in the second relative position relative to the body 300 of the cleaning device 1000, it transmits the detection information to the processing unit. When the processing unit determines that the cleaning module has reached the second relative position, it controls the drive unit to release the pressure applied to the drain assembly 30, so that the drain channel 31 is in a conductive state. When the cleaning module is cleaning the surface to be cleaned, the cleaning module can move to a first relative position relative to the body 300 of the cleaning device 1000. When the position detection unit detects that the cleaning module is in the first relative position relative to the body 300 of the cleaning device 1000, it transmits the detection information to the processing unit. When the processing unit determines that the cleaning module has reached the first relative position, the processing unit controls the drive unit to apply external force to the sewage discharge component 30 so that the sewage discharge channel 31 is in a closed state.

[0175] Please see Figure 9 Secondly, the embodiments of this application provide a cleaning device 1000, which includes a body 300 and a sewage discharge assembly 100 of the above embodiments, wherein the sewage tank 10 of the sewage discharge assembly 100 is installed on the body 300.

[0176] Thirdly, embodiments of this application provide a cleaning device 1000, which includes a body and a cleaning module as described above, the cleaning module being installed on the body 300.

[0177] Please see Figure 9 In some embodiments, the cleaning device 1000 further includes a driver 500 disposed on the body 300. The driver 500 is used to drive the cleaning module to move relative to the body 300 along the width direction of the body 300, so that the cleaning module switches between a first relative position and a second relative position. Specifically, when the cleaning device 1000 is cleaning a surface to be cleaned, the driver 500 drives the cleaning module to move along the width direction of the body 300, so that the cleaning module is in the first relative position relative to the body 300. When the drain assembly 100 needs to drain waste, the driver drives the cleaning module to move along the width direction of the body 300, so that the cleaning module is in the second relative position relative to the body 300.

[0178] Please see Figure 9In some embodiments, the cleaning device 1000 further includes a position sensor and a processor. The position sensor is disposed on the body 300 and is used to detect the relative position of the cleaning module and the body 300. The processor is used to determine whether the relative position of the cleaning module and the body 300 meets a predetermined condition based on the detection information from the position sensor, and controls the operation of the driver 500 based on the determination result.

[0179] Specifically, in some embodiments, when the processor receives a sewage discharge start command and the detection information indicates that the cleaning module is in a first relative position, the processor controls the driver 500 to drive the cleaning module to move forward relative to the body 300 along the width direction of the body 300; after the processor receives a sewage discharge start command and the detection information indicates that the cleaning module is in a second relative position, the processor controls the driver 500 to stop driving; when the processor receives a sewage discharge end command and the detection information indicates that the cleaning module is in the second relative position, the processor controls the driver 500 to drive the cleaning module to move backward relative to the body 300 along the width direction of the body 300; after the processor receives a sewage discharge end command and the detection information indicates that the cleaning module is in the first relative position, the processor controls the driver 500 to stop driving.

[0180] The position sensor is communicatively connected to the processor, which in turn is communicatively connected to the driver 500. The processor can control the driver 500 based on the detection results from the position sensor. When the cleaning module needs to be emptied, the processor can control the driver 500 to move the cleaning module to a second relative position.

[0181] When the cleaning equipment 1000 needs to discharge wastewater, the position sensor detects the position of the cleaning module relative to the body 300 and transmits this detection information to the processor. Upon receiving the discharge start command and determining that the cleaning module is in the first relative position, the processor controls the driver 500 to move the cleaning module forward along the width direction of the body 300, causing the cleaning module to protrude from one side of the body 300. When the position sensor detects that the cleaning module is in the second relative position, the position sensor transmits this detection information to the processor, which can then control the driver 500 to stop driving the cleaning module. When the cleaning module is in the second relative position, the discharge component 30 is in a discharge state under external force, allowing wastewater in the wastewater tank 10 to be discharged outside the cleaning equipment 1000.

[0182] When the cleaning equipment 1000 has completed its wastewater discharge, the position sensor detects the position of the cleaning module relative to the body 300 and transmits this information to the processor. Upon receiving the wastewater discharge start command and determining that the cleaning module is in the second relative position, the processor controls the driver 500 to move the cleaning module in the opposite direction along the width of the body 300. When the position sensor detects that the cleaning module is in the first relative position, the position sensor transmits this information to the processor, which can then control the driver 500 to stop driving the cleaning module. When the cleaning module is in the first relative position, the wastewater discharge component 30 is in an undischarged state, thus preventing waste from being discharged from the wastewater tank 10.

[0183] The cleaning device 1000 of this application switches the drain component 30 between a draining state and a non-draining state by applying external force to the outside of the drain channel 31. When the drain assembly 100 needs to drain, the drain component 30 can be in the draining state, so that the waste in the wastewater tank 10 can be discharged outside the drain assembly 100. Compared with the current drain component 30, the drain channel 31 of the drain component 30 of this application does not need to be equipped with a valve, so the drain channel 31 is not easily blocked, and the waste flows out of the drain channel 31 more smoothly.

[0184] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11 Fourthly, embodiments of this application also provide a base station 3000, which includes a main body 3001 and a second force-applying member 3003. The second force-applying member 3003 is installed on the main body 3001 and is used to cooperate with a sewage discharge member 30. When the external force applied by the second force-applying member 3003 to the outside of the sewage discharge channel 31 changes, the sewage discharge member 30 can switch between a non-discharged state and a discharged state.

[0185] The base station 3000 is a device used for the maintenance, upkeep, and charging of the cleaning equipment 1000. For example, the base station 3000 has a docking station where the cleaning equipment 1000 can enter to facilitate cleaning of its mopping components and charging. Furthermore, the base station 3000 may also have at least one of the following functions: replenishing water, draining water, collecting dust, and removing waste from the cleaning equipment 1000. When the mopping components of the cleaning equipment 1000 are dirty and / or have insufficient power, the cleaning equipment 1000 returns to the base station 3000 to clean the mopping components and / or recharge. After the mopping components of the cleaning equipment 1000 are cleaned and / or fully charged, the cleaning equipment 1000 can leave the base station 3000 and continue cleaning the surface to be cleaned.

[0186] In one embodiment, when the cleaning device 1000 enters the base station 3000 and needs to be drained, the second force-applying member 3003 applies an external force to the side wall of the draining member 30, thereby switching the draining member 30 from a non-draining state to a draining state. Dirt in the receiving cavity 11 can flow into the base station 3000 from the drain port 311. In another embodiment, when the cleaning device 1000 enters the base station 3000 and needs to be drained, the second force-applying member 3003 removes the external force applied to the side wall of the draining member 30, thereby switching the draining member 30 from a non-draining state to a draining state. Dirt in the receiving cavity 11 can flow into the base station 3000 from the drain port 311.

[0187] After the cleaning device enters the base station 3000, it will come into contact with the tray of the main body 3001. Preferably, the second force-applying member 3003 can be installed on the tray, and the second force-applying member 3003 can be detachably or non-detachably connected to the tray. When the second force-applying member 3003 is installed on the tray, it is convenient for the second force-applying member 3003 to cooperate with the sewage discharge member 30.

[0188] Please see Figure 1 and Figure 2 In some embodiments, when the drain component 30 is in the draining state, the height of the drain outlet 311 of the drain component 30 is lower than the height of the drain outlet 311 when the drain component 30 is in the non-draining state.

[0189] The drain component 30 can rotate relative to the wastewater tank 10. During the rotation of the drain component 30, the height of the drain port 311 in the height direction H of the wastewater tank 10 is variable. When the cleaning module is cleaning the surface to be cleaned, under the action of external force, the drain component 30 can rotate relative to the wastewater tank 10 in a first direction, so that the height of the drain port 311 is higher, making it difficult for dirt to flow out from the drain port 311. At this time, the drain component 30 is in a non-drained state. When the drain component 100 needs to drain, under the action of external force, the drain component 30 can rotate relative to the wastewater tank 10 in a second direction, so that the height of the drain port 311 is lower, and the dirt in the drain channel 31 can flow out from the drain port 311. At this time, the drain component 30 is in a draining state. The drain component 30 switches between the draining state and the non-draining state by rotating, and the flow of dirt from the drain channel 31 is relatively smooth, and there is no problem of blockage inside the drain channel 31.

[0190] Please see Figure 2 , Figure 12 , Figure 13 and Figure 14In some embodiments, the second force-applying member 3003 includes a guide portion 3005 and a connecting portion 3007. The guide portion 3005 is provided with a guide surface 3006, which mates with the mating surface 331. The connecting portion 3007 is connected to the main body 3001.

[0191] Specifically, the connecting part 3007 is used to connect the second force-applying member 3003 to the main body 3001, so that the second force-applying member 3003 is securely installed on the main body 3001. In one embodiment, after the cleaning device 1000 enters the base station 3000, the guide surface 3006 engages with the mating surface 331. The guide part 3005 transmits external force to the drain member 30 through the guide surface 3006, so that the drain member 30 can rotate in the first direction. When the drain member 30 switches from the undrained state to the drained state, the dirt in the receiving cavity 11 flows into the base station 3000 from the drain port 311. When the cleaning module leaves the base station 3000, the second force-applying member 3003 is spaced apart from the drain member 30, that is, the guide surface 3006 is spaced apart from the mating surface 331. When the external force on the drain member 30 disappears, the reset member 40 can drive the drain member 30 to rotate in the second direction, and the drain member 30 switches from the drained state to the undrained state.

[0192] In another embodiment, after the cleaning device 1000 enters the base station 3000, when the cleaning module moves to a second relative position relative to the body 300, the second force-applying member 3003 cooperates with the sewage discharge member 30, that is, the guide surface 3006 cooperates with the mating surface 331. The guide portion 3005 transmits external force to the sewage discharge member 30 through the guide surface 3006, so that the sewage discharge member 30 can rotate in the first direction. When the sewage discharge member 30 switches from a non-sewage discharge state to a sewage discharge state, the dirt in the receiving cavity 11 flows into the base station 3000 from the sewage discharge port 311. When the cleaning module moves to the first relative position relative to the body 300, the second force-applying member 3003 and the sewage discharge member 30 are spaced apart, that is, the guide surface 3006 and the mating surface 331 are spaced apart. When the external force on the sewage discharge member 30 disappears, the reset member 40 can drive the sewage discharge member 30 to rotate in the second direction, and the sewage discharge member 30 switches from a sewage discharge state to a non-sewage discharge state.

[0193] In another embodiment, after the cleaning device 1000 enters the base station 3000, the second force-applying member 3003 can move relative to the main body 3001 to the position corresponding to the drain member 30, so that the second force-applying member 3003 can cooperate with the drain member 30, that is, the guide surface 3006 cooperates with the mating surface 331. The guide part 3005 transmits external force to the drain member 30 through the guide surface 3006, so that the drain member 30 can rotate in the first direction. When the drain member 30 switches from the non-drainage state to the drainage state, the dirt in the receiving cavity 11 flows into the base station 3000 from the drainage port 311. When the cleaning module moves relative to the body 300 to the first relative position, the second force-applying member 3003 is spaced apart from the drain member 30, that is, the guide surface 3006 is spaced apart from the mating surface 331. When the external force on the drain component 30 disappears, the reset component 40 can drive the drain component 30 to rotate in the second direction, and the drain component 30 switches from the drain state to the non-drain state.

[0194] In this embodiment of the application, after the cleaning equipment 1000 enters the base station 3000, when the cleaning module moves to the second relative position relative to the body 300, the second force-applying component 3003 cooperates with the sewage discharge component 30.

[0195] Please see Figures 11 to 14 In some embodiments, the body 3001 includes a bottom wall and a side wall extending from the bottom wall, and the distance between the guide surface 3006 and the bottom wall gradually decreases in the width of the body 3001 and in the direction close to the side wall.

[0196] In the height direction H of the sewage tank 10, after the cleaning equipment 1000 enters the base station 3000, the second force-applying component 3003 is higher than the sewage discharge component 30. The guide surface 3006 is located on the bottom surface of the guide portion 3005. When the sewage discharge component 30 is in the sewage discharge state, the mating surface 331 is located on the top surface of the sewage discharge component 30. The guide surface 3006 is an inclined surface facing the side wall, and the bottom wall is a horizontal surface. In the direction close to the side wall, the distance between the guide surface 3006 and the bottom wall gradually decreases. During the process of the cleaning module moving relative to the body 300 to the second relative position, the guide surface 3006 and the mating surface 331 begin to mate ( Figure 12 As shown). At this time, the angle between the mating surface 331 extending away from the body 20 and the direction from the bottom to the top of the sewage tank 10 can be in the range of [0°, 90°]. During the mating process between the guide surface 3006 and the mating surface 331, the angle between the mating surface 331 and the direction from the bottom to the top of the sewage tank 10 gradually increases ( Figure 13 As shown). After the sewage discharge assembly 100 moves to the second relative position relative to the body 300, the mating surface 331 mates with the lowest point of the guide surface 3006. At this time, the angle between the mating surface 331 and the height direction H of the sewage tank 10 can be greater than or equal to 90°. Figure 14(As shown). During the engagement of the guide surface 3006 and the mating surface 331, the drain outlet 311 begins to rotate along the first direction. In the height direction H of the sewage tank 10, the height of the drain outlet 311 gradually decreases. When the mating surface 331 engages with the guide surface 3006 at its lowest point, the angle between the extension direction of the drain outlet 311 toward the central axis of the drain inlet 313 away from the drain component 30 and the height direction from the bottom to the top of the sewage tank 10 is greater than or equal to 90°. At this time, the drain component 30 switches to the draining state, and the sewage in the receiving cavity 11 can flow into the base station 3000 from the drain outlet 311.

[0197] Please see Figures 11 to 14 Furthermore, in some embodiments, the main body 3001 includes a bottom wall and side walls extending from the bottom wall. The distance between the guide surface 3006 and the bottom wall gradually decreases in the direction in which the cleaning module enters the main body 3001. During the process of the cleaning device 1000 entering the base station 3000, in the direction in which the cleaning module enters the main body 3001, the guide surface 3006 guides the mating surface 331, thereby further accelerating the rotation of the discharge component 30 along the first direction, allowing the contaminants in the receiving cavity 11 to be quickly discharged into the base station 3000.

[0198] Please see Figure 1 , Figure 15 and Figure 16 In some embodiments, the sewage discharge assembly 100 is further provided with a clamping member 81; the second force-applying member 3003 is used to apply an external force to the sewage discharge member 30 through the clamping member 81, so that the sewage discharge channel 31 is in a conducting state or a closed state. Specifically, in some embodiments, when the second force-applying member 3003 applies an external force to the side wall of the sewage discharge member 30 through the clamping member 81, the sewage discharge channel 31 is in a closed state; when the external force applied to the sewage discharge member 3003 by the second force-applying member 3003 through the clamping member 81 disappears, the sewage discharge channel 31 is in a conducting state.

[0199] The sidewall of the drain component 30 can deform under external force. When the drain channel 31 is open, the drain component 30 is in a draining state. When the drain channel 31 is closed, the drain component 30 is in a non-draining state. When the drain component 30 is in a draining state, the height of the drain outlet 311 relative to the sewage tank 10 is the same as when the drain component 30 is in a non-draining state.

[0200] The clamping member 81 cooperates with the second force-applying member 3003, which applies an external force to the clamping member 81. This allows the clamping member 81 to apply an external force to the drain member 30, keeping the drain channel 31 closed. When the cleaning module is cleaning the surface to be cleaned, the clamping member 81 maintains the external force applied to the drain member 30, preventing contaminants in the receiving cavity 11 from flowing out of the drain port 311 to the surface to be cleaned. After the device module enters the base station 3000, the second force-applying member 3003 can release the external force applied by the clamping member 81 to the drain member 30, allowing contaminants to flow into the base station 3000 from the drain port 311. After the drain assembly 100 has finished draining, the second force-applying member 3003 applies an external force to the clamping member 81, which in turn applies an external force to the drain member 30, keeping the drain channel 31 closed.

[0201] Please see Figure 15 and Figure 16 In one embodiment, when the cleaning device 1000 enters the base station 3000, the second force-applying member 3003 engages with the clamping member 81. The second force-applying member 3003 can release the external force of the clamping member 81 on the drain member 30, leaving the drain member 30 in a natural state. This allows the drain channel 31 to be open, and the drain member 30 to be in a draining state, enabling waste to flow out from the drain port 311. At this time, the drain channel 31 has a large cross-sectional area, allowing waste to flow out quickly. When the cleaning device 1000 has completed draining, the second force-applying member 3003 can apply pressure to the side wall of the drain member 30 through the clamping member 81. This causes the drain member 30 to deform, closing the drain channel 31 and leaving the drain member 30 in a draining state. Waste in the receiving cavity 11 cannot be discharged from the drain port 311.

[0202] In another embodiment, after the cleaning device 1000 enters the base station 3000, when the cleaning module moves to a second relative position relative to the body 300, the second force-applying member 3003 cooperates with the clamping member 81. The second force-applying member 3003 can release the external force of the clamping member 81 on the drain member 30, the drain member 30 is in a natural state, thus the drain channel 31 is in a conductive state, the drain member 30 is in a draining state, and the dirt can flow out from the drain port 311. In yet another embodiment, after the cleaning device 1000 enters the base station 3000, the second force-applying member 3003 can move relative to the main body 3001 to the position corresponding to the drain member 30, so that the second force-applying member 3003 can cooperate with the clamping member 81. The second force-applying component 3003 and the removable clamping component 81 exert external force on the sewage discharge component 30, so that the sewage discharge component 30 is in a natural state, the sewage discharge channel 31 is in a conductive state, the sewage discharge component 30 is in a sewage discharge state, and the sewage can flow out from the sewage discharge port 311.

[0203] Please see Figure 15 and Figure 16 Furthermore, in some embodiments, the base station 3000 also includes a driving structure connected to the second force-applying member 3003. The driving structure is used to drive the second force-applying member 3003 to apply or remove the applied external force to the sewage discharge member 30. Specifically, when the cleaning equipment 1000 enters the base station 3000 and the sewage discharge assembly 100 needs to discharge sewage, the driving member 70 drives the second force-applying member 3003 to remove the external force applied to the sewage discharge member 30 by the clamping member 81, so that the sewage discharge channel 31 is in a conductive state. After the sewage discharge assembly 100 has finished discharging sewage, the driving member 70 drives the second force-applying member 3003 to apply external force to the side wall of the sewage discharge member 30 through the clamping member 81, so that the sewage discharge channel 31 is in a closed state.

[0204] Please see Figure 15 and Figure 16 In some embodiments, the base station 3000 further includes a position detection unit and a processing unit. The position detection unit is used to detect the position of the cleaning module relative to the body 300 of the cleaning equipment 1000 or the position of the cleaning module relative to the base station 3000. The processing unit is used to determine whether the position of the cleaning module relative to the body 300 or the base station 3000 meets predetermined conditions based on the detection information from the position detection unit, and to control the operation of the drive unit based on the determination result.

[0205] The position detection unit and processing unit here may have the same structure as the position detection unit and processing unit in the first aspect, or the position detection unit and processing unit here may have a different structure from the position detection unit and processing unit in the first aspect.

[0206] In one embodiment, when the position detection unit detects that the cleaning module has entered the base station 3000, the position detection unit transmits the detection information to the processing unit. If the processing unit determines that the position of the cleaning module relative to the base station 3000 meets predetermined conditions, the processing unit controls the drive unit to drive the second force-applying member 3003 to operate, so that the second force-applying member 3003 removes the external force applied by the clamping member 81 to the sewage discharge member 30. When the position detection unit detects that the cleaning module is about to leave the base station 3000, the position detection unit transmits the detection information to the processing unit. The processing unit controls the drive unit to drive the second force-applying member 3003 to operate, and the second force-applying member 3003 applies an external force to the clamping member 81, thereby the clamping member 81 applies an external force to the sewage discharge member 30.

[0207] In another embodiment, when the position detection unit detects that the cleaning module has moved to a second relative position relative to the body 300, the position detection unit transmits the detection information to the processing unit. If the processing unit determines that the cleaning module is in the second relative position, the processing unit controls the drive unit to operate the second force-applying member 3003, causing the second force-applying member 3003 to remove the external force applied by the clamping member 81 to the drain member 30. When the position detection unit detects that the cleaning module has moved to a first relative position relative to the body 300, the position detection unit transmits the detection information to the processing unit. If the processing unit determines that the cleaning module is in the first relative position, the processing unit controls the drive unit to operate the second force-applying member 3003, which applies an external force to the clamping member 81, thereby causing the clamping member 81 to apply an external force to the drain member 30.

[0208] The base station 3000 of this application applies an external force to the outside of the sewage discharge channel 31 to switch the sewage discharge component 30 between a sewage discharge state and a non-sewage discharge state. When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge component 30 can be in the sewage discharge state, so that the sewage in the sewage tank 10 can be discharged outside the sewage discharge assembly 100. Compared with the current sewage discharge component 30, the sewage discharge channel 31 of the sewage discharge component 30 of this application does not need to be equipped with a valve, so the sewage discharge channel 31 is not easy to be blocked, and the sewage flows out of the sewage discharge channel 31 more smoothly.

[0209] Please see Figure 17 Fourthly, embodiments of this application also provide a cleaning system 10000, which includes the cleaning device 1000 of the above embodiments; and / or the base station 3000 of the above embodiments.

[0210] The cleaning system 10000 of this application applies external force to the outside of the sewage discharge channel 31 to switch the sewage discharge component 30 between a sewage discharge state and a non-sewage discharge state. When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge component 30 can be in the sewage discharge state, so that the sewage in the sewage tank 10 can be discharged outside the sewage discharge assembly 100. Compared with the current sewage discharge component 30, the sewage discharge channel 31 of the sewage discharge component 30 of this application does not need to be equipped with a valve, so the sewage discharge channel 31 is not easy to be blocked, and the sewage flows out of the sewage discharge channel 31 more smoothly.

[0211] Fifthly, embodiments of this application also provide a sewage control method. This method is applied to the sewage component 100, cleaning module, cleaning equipment 1000, base station 3000, and cleaning system 10000 described above. The sewage control method includes:

[0212] Please see Figure 1 , Figure 2 and Figure 1801: When the cleaning equipment 1000 moves to the designated sewage discharge position, the sewage discharge component 30 is switched to the sewage discharge state; and

[0213] 03: When the cleaning equipment 1000 has completed the sewage discharge, control the sewage discharge component 30 to switch to the non-discharge state.

[0214] Specifically, when the cleaning equipment 1000 moves to the designated sewage discharge location, including 011: the cleaning equipment 1000 moves to the docking position of the base station 3000. That is, only when the cleaning equipment 1000 is at the docking position can the sewage of the cleaning equipment 100 be discharged outside the cleaning equipment 100 through the sewage discharge component 100, and the sewage is collected by the base station 3000 or discharged into the sewer pipe through the base station 3000.

[0215] The drive unit 70 or drive unit controls the drain component 30 to switch from a non-drainage state to a drainage state. Wastewater in the receiving cavity 11 flows through the connecting pipe 60 and the wastewater tank 50, and enters the drain channel 31 through the inlet 313, finally being discharged from the drain outlet 311 to the outside of the cleaning equipment 1000. When the cleaning equipment 1000 has completed draining, the drive unit 70 or drive unit controls the drain component 30 to switch from a drainage state to a non-drainage state, thus preventing the wastewater in the receiving cavity 11 from being discharged from the drain outlet 311 to the outside of the cleaning equipment 1000.

[0216] Please see Figure 1 , Figure 2 , Figure 19 and Figure 20 In some embodiments, the discharge component 30 can rotate relative to the sewage tank 10 to switch between a non-discharge state and a discharge state. When the discharge component 30 is in the discharge state, the height of the discharge port 313 is lower than the height of the discharge port 313 when the discharge component 30 is in the non-discharge state; 01: When the cleaning equipment 1000 moves to the designated discharge position, controlling the discharge component 30 to switch to the discharge state also includes:

[0217] 013: Control the sewage discharge component 30 to rotate relative to the sewage tank 10 in the first direction.

[0218] When the cleaning equipment 1000 needs to discharge wastewater, the drive unit 70 can drive the discharge unit 30 to rotate relative to the wastewater tank 10 in a first direction. The drive unit 70 is connected to the force-receiving part 33 of the discharge unit 30, and the drive unit 70 applies an external force to the force-receiving part 33, so that the discharge unit 30 can rotate in the first direction. In the height direction H of the wastewater tank 10, the height of the discharge port 311 gradually decreases. When the discharge port 311 is lower than the inlet port 313, or when the discharge port 311 is flush with the inlet port 313, the discharge unit 30 stops rotating, and at this time the discharge unit 30 switches from the non-discharge state to the discharge state. The waste in the receiving cavity 11 can pass through the connecting pipe 60, the wastewater tank 50 and the discharge channel 31, and be discharged from the discharge port 311 to the outside of the cleaning equipment 1000.

[0219] In another embodiment, when the cleaning equipment 1000 needs to discharge wastewater, and the cleaning equipment 1000 is docked at the base station docking position, 013: control the discharge component 30 to rotate relative to the wastewater tank 10 in a first direction, including: 0131: control the cleaning module of the cleaning equipment 1000 to move in the positive direction of the width of the cleaning equipment 1000 relative to the body of the cleaning equipment 1000 so that the cleaning module reaches a second relative position, so that the discharge component cooperates with the force application component of the base station 3000 to drive the discharge component to rotate in the first direction. In this way, the discharge component 30 can be switched from a non-discharge state to a discharge state, realizing the discharge of wastewater by the cleaning equipment 1000 at the base station 3000.

[0220] Please see Figure 1 , Figure 2 , Figure 19 and Figure 20 In some embodiments, 03: When the cleaning equipment 1000 has completed the sewage discharge, the sewage discharge component 30 is switched to a non-discharge state, including:

[0221] 033: Control the sewage discharge component 30 to rotate relative to the sewage tank 10 in the second direction.

[0222] In one embodiment, after the cleaning equipment 1000 has completed its wastewater discharge, the drive member 70 can drive the discharge member 30 to rotate relative to the wastewater tank 10 in a second direction. The drive member 70 is connected to the force-receiving part 33 of the discharge member 30, and the drive member 70 applies an external force to the force-receiving part 33, thereby allowing the discharge member 30 to rotate in the second direction. In the height direction H of the wastewater tank 10, the height of the discharge port 311 gradually increases. When the discharge port 311 is higher than the inlet port 313, the discharge member 30 stops rotating, and at this time, the discharge member 30 switches from the discharge state to the non-discharge state. The waste in the receiving cavity 11 cannot be discharged from the discharge port 311 to outside the cleaning equipment 1000.

[0223] In another embodiment, after the cleaning equipment 1000 has completed its wastewater discharge, the drive member 70 removes the external force applied to the discharge member 30, and the reset member 40 can drive the discharge member 30 to rotate in the second direction. In the height direction H of the wastewater tank 10, the height of the discharge port 311 gradually increases. When the discharge port 311 is higher than the inlet port 313 and the reset member 40 returns to its natural state, the discharge member 30 stops rotating, and at this time, the discharge member 30 switches from the discharge state to the non-discharge state. The waste in the receiving cavity 11 cannot be discharged from the discharge port 311 to outside the cleaning equipment 1000.

[0224] In another embodiment, after the cleaning equipment 1000 has completed its sewage discharge, the drive member 70 removes the external force applied to the sewage discharge member 30, and the reset member 40 can drive the sewage discharge member 30 to rotate in the second direction. Specifically, 031: when the cleaning equipment 1000 leaves the base station docking position, 033: controlling the sewage discharge member 30 to rotate relative to the sewage tank 10 in the second direction includes: 0331: controlling the cleaning module of the cleaning equipment 1000 to move in the opposite direction of the width of the cleaning equipment 1000 relative to the body of the cleaning equipment 1000 so that the cleaning module reaches a first relative position, so that the sewage discharge member 30 moves away from the force-applying member of the base station 3000 and rotates in the second direction. This switches the sewage discharge member 30 from the sewage discharge state to the non-sewage discharge state, ensuring that the sewage in the sewage tank 10 of the cleaning equipment 1000 does not flow out.

[0225] Please see Figure 7 , Figure 8 and Figure 21 In some embodiments, the drain component 30 can deform under external force on the outside of the drain channel 31 to switch between a non-drainage state and a drainage state. When the drain component 30 is in the drainage state, the drain channel 31 is in a conductive state; when the drain component 30 is in the non-drainage state, the drain channel 31 is in a closed state. 01: When the cleaning equipment 1000 moves to the designated drainage position, controlling the drain component 30 to switch to the drainage state includes:

[0226] 015: Control the sewage discharge channel 31 to be in the conductive state. When the cleaning equipment 1000 needs to discharge sewage, the drive unit can drive the first force-applying member 80 to change the external force applied to the sewage discharge member 30. The sewage discharge member 30 can deform under force, and the drive unit drives the first force-applying member 80 to remove the external force applied to the sewage discharge member 30. The sewage discharge member 30 is in its natural state, so the sewage discharge channel 31 is in the conductive state, and the sewage discharge member 30 is in the sewage discharge state. The sewage in the receiving cavity 11 can pass through the connecting pipe 60, the sewage tank 50 and the sewage discharge channel 31, and be discharged from the sewage outlet 311 to the outside of the cleaning equipment 1000.

[0227] Please see Figure 7 , Figure 8 and Figure 20 In some embodiments, 03: When the cleaning equipment 1000 has completed the sewage discharge, the sewage discharge component 30 is switched to a non-discharge state, including:

[0228] 035: The drain channel 31 is kept closed. After the cleaning equipment 1000 has finished draining, the drive unit can drive the first force-applying member 80 to change the external force applied to the drain member 30. The drive unit drives the first force-applying member 80 to apply an external force to the drain member 30, causing the drain member 30 to deform, thereby closing the drain channel 31 and putting the drain member 30 in a draining state. Dirt in the receiving cavity 11 cannot be discharged from the drain port 311 to outside the cleaning equipment 1000.

[0229] The control method of the cleaning equipment 1000 according to this application applies an external force to the outside of the sewage discharge channel 31 to switch the sewage discharge component 30 between a sewage discharge state and a non-sewage discharge state. When the sewage discharge assembly 100 needs to discharge sewage, the sewage discharge component 30 can be in the sewage discharge state, so that the sewage in the sewage tank 10 can be discharged outside the sewage discharge assembly 100. Compared with the current sewage discharge component 30, the sewage discharge channel 31 of the sewage discharge component 30 of this application does not need to be equipped with a valve, so the sewage discharge channel 31 is not easy to be blocked, and the sewage flows out of the sewage discharge channel 31 more smoothly.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
