[0125] 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.

[0126] 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.

[0127] Cleaning robots effectively clean surfaces, freeing up people's hands, and are increasingly entering homes. However, after cleaning a surface, the mop of a cleaning robot accumulates wastewater. Continuing to clean surfaces with this wastewater reduces cleaning efficiency. Furthermore, after cleaning a certain area, the robot needs to return to the base station to clean the mop, resulting in low cleaning efficiency and limited surface cleaning effectiveness. Therefore, cleaning robots typically incorporate a wastewater recovery system to collect wastewater from the mop, keeping it relatively clean and improving surface cleaning performance. This reduces the need for frequent returns to the base station and increases cleaning efficiency. However, with long-term wastewater collection, the wastewater recovery system accumulates dirt, requiring manual cleaning, which is inefficient. To address this issue, this application provides a water system 100 (… Figure 1 As shown), cleaning module 200 ( Figure 1 (As shown), cleaning equipment 1000 ( Figure 17 As shown), base station 3000 ( Figure 18 (As shown), Cleaning System 10000 ( Figure 25 (as shown) and cleaning methods for the water system ( Figure 26 (As shown).

[0128] Please see Figures 1 to 4 In a first aspect, embodiments of this application provide a water system 100, which includes a sewage link 10 and a power system 20. The sewage link 10 includes a sewage channel 11 and a sewage tank 30. The sewage channel 11 is used for sewage flow, and the sewage tank 30 has a receiving cavity 31 and an opening 32. The receiving cavity 31 is connected to the sewage channel 11 through the opening 32 and is used to store waste from the sewage channel 11. The opening 32 is used for discharging waste from the receiving cavity 31. The power system 20 is connected to the sewage link 10 and is used to switch between a first state and a second state. When the power system 20 is in the first state, it causes waste to enter the receiving cavity 31 from the sewage channel 11. When the power system 20 is in the second state, it causes waste to pass sequentially through the sewage tank 30 and the sewage channel 11 and be discharged outside the sewage link 10.

[0129] Specifically, please combine Figure 15 The water system 100 is a structure applied to the cleaning module 200. The water system 100 is used to collect wastewater from the cleaning module 200 when cleaning the surface to be cleaned and to discharge this wastewater to a designated location. The cleaning module 200 is a structure applied to the cleaning equipment 1000, used to clean the surface to be cleaned. The surface to be cleaned can be, but is not limited to, floor, marble, or glass surfaces. This application uses a floor as an example for illustration. The cleaning equipment 1000 is a device used to clean the surface to be cleaned. For example, the cleaning equipment 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 the above two robots, that is, a sweeping and mopping robot can be used to sweep and wipe the surface to be cleaned, and a handheld floor scrubber can be used to wipe the surface to be cleaned. The cleaning equipment 1000 in this application is illustrated using a combined sweeping and mopping robot as an example.

[0130] In some embodiments, the cleaning device 1000 may include a tracked cleaning robot or a roller cleaning robot. In some embodiments, the cleaning module 200 also includes a cleaning component 203, which may include a tracked mopping component 203 or a roller brush. When the cleaning device 1000 is a tracked cleaning robot, the mopping component 203 is a tracked mopping component 203. When the cleaning device 1000 is a roller cleaning robot, the mopping component 203 is a roller brush.

[0131] Both the tracked mop 203 and the roller brush can rotate to clean the surface to be cleaned. Compared to cleaning equipment 1000 that uses traditional disc-type mops 203, the tracked and roller mops 203 have a larger contact area with the surface to be cleaned due to their rotation. Simultaneously, debris on the mops 203 is continuously collected onto the cleaning equipment 1000, keeping the mops 203 relatively clean. Therefore, the cleaning equipment 1000 achieves better cleaning results on the surface to be cleaned. This application uses a tracked mop 203 as an example for explanation. When the cleaning equipment 1000 is a tracked cleaning robot, the cleaning module 200 cleans the tracked mop 203 while it rotates to clean the surface. Since the wastewater tank 30 can collect the waste from the mop, it remains relatively clean, and the cleaning module 200 achieves better cleaning results on the surface to be cleaned.

[0132] Please see Figures 2 to 4 The cleaning module 200 also includes a scraper 205. When the mop 203 is cleaning the surface to be cleaned, the scraper 205 scrapes off the dirt from the mop 203, and the dirt enters the wastewater link 10. The wastewater link 10 is used to collect the dirt from the mop 203 and can discharge the dirt to a designated location. When the scraper 205 scrapes off the dirt from the mop 203, the dirt enters the receiving cavity 31 through the wastewater channel 11 and the connecting pipe 13 of the wastewater link 10, and is stored in the receiving cavity 31. The receiving cavity 31 is used to store the dirt scraped off by the scraper 15 to prevent the dirt from falling onto the surface to be cleaned. If a wastewater tank 30 is provided on the water system 100, the wastewater tank 30 can collect and store the dirt scraped off by the scraper 15 from the mop 203, thus keeping the mop 203 relatively clean, and the cleaning module 200 achieves a better cleaning effect on the surface to be cleaned. The cleaning module 200 does not need to frequently visit the base station 3000. Figure 16As shown, the cleaning mop 203 and cleaning module 200 have high cleaning efficiency for the surface to be cleaned. The contaminants here may include liquid wastewater and / or solid dirt. The wastewater tank 30 is made of materials including, but not limited to, metal or plastic. Metal materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys. When the wastewater tank 30 is made of metal, it has high strength and a long service life. When the wastewater tank 30 is made of plastic, it has lower material costs and is lighter, making it easier to transport and handle. The cross-sectional shape of the wastewater tank 30 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0133] Please see Figure 1 and Figure 2 The wastewater channel 11 is connected to both the wastewater tank 30 and the scraper 15. When the cleaning module 200 is cleaning the surface to be cleaned, the water system 100 is used to collect the dirt from the scraper 203. The scraper 15 scrapes off the dirt from the scraper 203, and the scraped dirt enters the wastewater channel 11. The wastewater channel 11 transports the dirt scraped off by the scraper 15 from the scraper 203 through the opening 32 to the receiving cavity 31 of the wastewater tank 30, thus preventing the dirt scraped off by the scraper 15 from falling onto the surface to be cleaned and causing secondary contamination. When the cleaning module 200 needs to be drained, the water system 100 is used to drain the dirt, and the wastewater channel 11 allows the dirt in the receiving cavity 31 to be discharged through the opening 32, and the dirt is discharged outside the cleaning module 200 through the wastewater channel 11. When external liquid enters the wastewater tank 30 to clean it, the wastewater channel 11 also serves to discharge the liquid and waste in the receiving cavity 31 to the outside of the cleaning module 200. The wastewater channel 11 is not limited to a wastewater tank or pipe; this application uses a wastewater tank as an example. The liquid here includes, but is not limited to, clean water, cleaning fluid, or a mixture containing cleaning fluid. When the liquid is a mixture containing cleaning fluid, after entering the wastewater tank 30, the liquid can effectively dissolve stubborn stains on the inner wall of the wastewater tank 30, resulting in a good cleaning effect. Similarly, when liquid flows into the wastewater channel 11, it can also effectively dissolve stubborn stains in the wastewater channel 11, resulting in a good cleaning effect.

[0134] In the water system 100, the collection and discharge of waste from the mopping component 203 both pass through the wastewater link 10. Since the water system 100 uses a single link channel for both waste collection and discharge, it eliminates the need for additional channels, resulting in a simpler structure and easier manufacturing.

[0135] When wastewater flows through the wastewater channel 11, some wastewater will remain in the wastewater channel 11, resulting in the accumulation of dirt. When external liquid enters the wastewater tank 30 to clean it, the cleaned liquid will flow from the receiving cavity 31 into the wastewater channel 11. The liquid entering the wastewater channel 11 can flush the wastewater channel 11, and the liquid can carry the wastewater in the wastewater channel 11 out to the outside of the wastewater link 10, thus preventing excessive dirt accumulation in the wastewater tank 30 and wastewater channel 11, keeping them in a relatively clean state. The wastewater link 10 has high cleaning efficiency and does not require manual cleaning, resulting in a better user experience. When external liquid cleans the wastewater tank 30, it can also clean the wastewater channel 11 simultaneously, thus requiring less liquid to clean the wastewater link 10 and saving liquid usage. Furthermore, the liquid sequentially cleans the wastewater tank 30 and the wastewater channel 11. The cleaning time required for the wastewater channel 10 is shorter, the cleaning efficiency of the wastewater channel 10 is higher, and the cleaning effect of the wastewater channel 10 is better. Preferably, in the length direction of the wastewater channel 11, the length of the wastewater channel 11 can be greater than or equal to the length of the scraper 15, so that the wastewater channel 11 can receive the dirt scraped off by the scraper 15 from the mop 203, which can prevent the dirt scraped off by the scraper 15 from falling onto the surface to be cleaned.

[0136] The power system 20 is used to allow waste to enter the wastewater link 10 and to discharge waste from the wastewater link 10. The power system 20 may be an air pump assembly 60. When the power system 20 is an air pump assembly 60, the air pump assembly 60 can extract gas from the wastewater link 10 and pump air into the wastewater link 10. In the first state, the air pump assembly 60 extracts gas from the wastewater link 10, resulting in a lower air pressure in the wastewater link 10, allowing waste to enter. In the second state, the air pump assembly 60 pumps air into the wastewater link 10, increasing the air pressure and allowing waste to be discharged from the wastewater link 10.

[0137] The power system 20 may also include an electronic control component. When the cleaning module 200 is cleaning the surface to be cleaned, the power system 20 is in a first state, where the electronic control component controls the air pump assembly 60 to draw air from the wastewater link 10, and the dirt scraped by the scraper 205 from the mop 203 can enter the receiving cavity 31 through the wastewater channel 11. When the dirt in the wastewater tank 30 needs to be discharged, or when external liquid is used to clean the wastewater link 10, the power system 20 is in a second state, where the electronic control component controls the air pump assembly 60 to pump air towards the wastewater link 10, and the dirt in the receiving cavity 31 can be discharged outside the wastewater link 10 through the wastewater channel.

[0138] In the water system 100 of this embodiment, the power system 20 switches between a first state and a second state. Waste in the sewage channel 11 can enter and be stored in the receiving cavity 31. Liquid and waste in the receiving cavity 31 can also be discharged outside the water system 100 through the sewage channel 11. When the external liquid cleans the sewage tank 30, liquid in the receiving cavity 31 can flow through the sewage channel 11, cleaning the sewage channel 11. The liquid can also carry waste from the sewage link 10 and discharge it outside the water system 100. Compared to the current water system 100, the sewage link 10 in this embodiment has higher cleaning efficiency, does not accumulate more dirt, and does not require manual cleaning, resulting in a better user experience.

[0139] The water system 100 will be further described below with reference to the attached diagram.

[0140] In some embodiments, the location where dirt enters the sewage channel 11 when the power system 20 is in the first state differs from the location where dirt is discharged through the sewage channel 11 when the power system 20 is in the second state. Specifically, in the first state, dirt from the wiping member 203 enters the sewage channel 11 and then flows into the receiving cavity. In the second state, dirt in the receiving cavity 31 flows into the sewage channel 11 and out through the drain 50 of the sewage link 10 to the water system 100. This prevents dirt discharged from the receiving cavity 31 from flowing out from the location where it enters the sewage channel 11, thus avoiding the problem of dirt flowing onto the surface to be cleaned.

[0141] Please see Figure 1 and Figure 2 In some embodiments, the sewage link 10 further includes a connecting pipe 13, one end of which is connected to the sewage tank 30 and the other end of which is connected to the sewage channel 11. The connecting pipe 13 is used to allow the waste in the sewage channel 11 to enter the receiving cavity 31, and the connecting pipe 13 is also used to allow the liquid and waste in the receiving cavity 31 to be discharged through the sewage channel 11 to the outside of the sewage link 10.

[0142] Specifically, the sewage tank 30, connecting pipe 13, and sewage channel 11 are connected in sequence. One end of the sewage tank 30 is connected to the connecting pipe 13, the other end of the connecting pipe 13 is connected to one end of the sewage channel 11, and the other end of the sewage channel 11 is connected to one end of the discharge component 50 of the sewage link 10. The receiving cavity 31 communicates with the inner cavity of the connecting pipe 13, the inner cavity of the connecting pipe 13 communicates with the sewage channel 11, and the sewage channel 11 communicates with the discharge channel 51. The connecting pipe 13 can be made of, but is not limited to, metal or plastic. When the connecting pipe 13 is made of metal, it has higher strength, better wear resistance, and a longer service life. When the connecting pipe 13 is made of plastic, it is lighter and less expensive.

[0143] Please combine Figure 3 and Figure 4 While the cleaning module 200 cleans the surface to be cleaned, the scraper 15 scrapes away dirt from the mop 203. The power system 20 is in its first state, and the scraped dirt falls into the sewage channel 11. The dirt entering the sewage channel 11 passes through the connecting pipe 13 and flows into the receiving cavity 31, thus preventing the dirt scraped by the scraper 15 from falling onto the surface to be cleaned and causing secondary contamination. When the cleaning module 200 needs to discharge wastewater, the power system 20 is in its second state. The wastewater flowing out of the receiving cavity 31 enters the connecting pipe 13 and flows into the sewage channel 11, allowing the wastewater to be discharged outside the cleaning module 200. When wastewater flows through the sewage channel 11 and the connecting pipe 13, some wastewater remains in the connecting pipe 13 and the sewage channel 11, resulting in the accumulation of dirt in these areas.

[0144] When cleaning the wastewater tank 30, the cleaned liquid flows from the receiving cavity 31 into the connecting pipe 13 and the wastewater channel 11. The liquid entering the connecting pipe 13 and the wastewater channel 11 flushes them, carrying away any contaminants and allowing them to flow out of the water system 100 through the drain 50. This prevents excessive buildup of dirt in the connecting pipe 13 and the wastewater channel 11, keeping them relatively clean. The wastewater link 10 requires no manual cleaning, its cleaning method is simple, and its cleaning efficiency is high.

[0145] Preferably, the liquid can soak the wastewater tank 30 to dissolve the dirt on the inner wall of the wastewater tank 30. After soaking the wastewater tank 30, the liquid carries the dirt in the receiving cavity 31 into the connecting pipe 13. At this time, the water pressure of the liquid and dirt flowing into the connecting pipe 13 is relatively high, and the liquid can effectively flush the inner wall of the connecting pipe 13 and the wastewater channel 11. The liquid can flow into various positions of the connecting pipe 13 and the wastewater channel 11, and carry the dirt from the connecting pipe 13 and the wastewater channel 11 out to the outside of the cleaning module 200. The liquid has a good cleaning effect on the connecting pipe 13 and the wastewater channel 11, and the connecting pipe 13 and the wastewater channel 11 can be kept in a relatively clean state.

[0146] Please see Figure 1 and Figure 2 In some embodiments, the connecting pipe 13 includes a connecting portion 131 and a bending portion 133. The connecting portion 131 is connected to the bending portion 133. One end of the bending portion 133 is connected to the sewage tank 30, and one end of the connecting portion 131 is connected to the sewage channel 11. In the height direction H of the sewage tank 30, the highest point of the bending portion 133 is higher than the connection between the connecting pipe 13 and the sewage tank 30.

[0147] The connecting pipe 13 is connected to the wastewater tank 30 through the opening 32. The opening 32 allows waste in the connecting pipe 13 to enter the receiving cavity 31, and also allows liquid and waste in the receiving cavity 31 to drain out of the receiving cavity 31. The connecting pipe 13 communicates with the receiving cavity 31 through the opening 32. If the receiving cavity 31 stores waste or the wastewater tank 30 is soaked by external liquid, and the sealing of the receiving cavity 31 is not good enough, liquid and waste in the receiving cavity 31 may flow out from the connecting pipe 13, causing leakage. The bend 133 prevents liquid and waste in the receiving cavity 31 from flowing out from the connecting pipe 13. In the height direction H of the wastewater tank 30, the highest point of the bend 133 is higher than the opening 32, so that liquid and waste flowing out from the opening 32 cannot cross the bend 133 and flow into the wastewater channel 11, thus preventing liquid and waste from flowing onto the surface to be cleaned.

[0148] Please continue reading. Figure 1 and Figure 2 In some embodiments, the sewage channel 11 includes a first opening 111 and a second opening 113 opposite each other in the length direction, the connecting pipe 13 is connected to the first opening 111, and the second opening 113 is used to discharge sewage to the outside of the sewage link 10.

[0149] When the cleaning module 200 needs to discharge wastewater, the waste flowing out of the receiving cavity 31 enters the connecting pipe 13 through the opening 32 and flows into the sewage channel 11 from the connecting pipe 13. The waste in the connecting pipe 13 enters the sewage channel 11 through the first opening 111. Due to the fluidity of the waste, it spreads and flows into various locations in the sewage channel 11. When the first opening 111 and the second opening 113 are located at opposite ends of the sewage channel 11, the waste entering the sewage channel 11 through the second opening 113 tends to flow towards the second opening 113, and almost all the waste in the sewage channel 11 can flow out of the water system 100 through the second opening 113.

[0150] When cleaning the wastewater tank 30, the liquid in the receiving cavity 31 flows into the connecting pipe 13 through the opening 32. The liquid can flow through various positions of the connecting pipe 13 and carry the dirt in the connecting pipe 13 into the wastewater channel 11. When the first opening 111 and the second opening 113 are located at opposite ends of the wastewater channel 11, the liquid in the connecting pipe 13 enters the wastewater channel 11 through the first opening 111 and can flow through various positions in the wastewater channel 11. The liquid can carry the dirt in the wastewater channel 11 and flow out through the second opening 113, thus the liquid has a better cleaning effect on the connecting pipe 13 and the wastewater channel 11.

[0151] Please see Figures 5 to 7 In some embodiments, the top of the sewage tank 30 is provided with a channel 33 and a plurality of outlets 35. The outlets 35 are spaced apart along the circumference of the sewage tank 30. The channel 33 is provided with an inlet 331 for allowing external liquid to enter the channel 33. The outlets 35 connect the channel 33 and the receiving cavity 31. The outlets 35 spray liquid toward the inner wall of the sewage tank 30 in a direction away from the center of the cross-section of the sewage tank 30.

[0152] Specifically, the receiving cavity 31 is used to store waste, and also to store external liquid entering from the inlet 331. The inlet 331 is used to allow external liquid to enter the channel 33, and can also be used to allow gas to enter the channel 33. When the wastewater tank 30 needs cleaning, external liquid enters the channel 33 from the inlet 331. This liquid includes, but is not limited to, clean water, cleaning fluid, or a mixture containing cleaning fluid. When the liquid entering the receiving cavity 31 from the inlet 331 is clean water, the cleaning cost of the wastewater tank 30 is lower. When the liquid entering the receiving cavity 31 from the inlet 331 is cleaning fluid or a mixture containing cleaning fluid, the mixture containing cleaning fluid can further dissolve stubborn stains on the inner wall of the wastewater tank 30, resulting in a better cleaning effect.

[0153] Please see Figures 5 to 7In the height direction H of the sewage tank 30, the opening 32 can be located at the bottom of the sewage tank 30, so that the liquid and dirt in the sewage tank 30 can be smoothly discharged from the opening 32 to the outside of the sewage tank 30 by gravity or pressure. Almost all the liquid and dirt in the sewage tank 30 can be discharged to the outside of the sewage tank 30 (if the height of the opening 32 is higher than the bottom of the sewage tank 30, the liquid and dirt in the sewage tank 30 below the opening 32 cannot be discharged from the sewage tank 30). When the dirt in the sewage tank 30 (here, the dirt is the dirt scraped off from the mop 203) is discharged through the opening 32, some dirt may remain in the sewage tank 30, so the sewage tank 30 usually needs to be cleaned. When the sewage tank 30 needs to be cleaned, liquid enters the channel 33 from the inlet 331 and is sprayed into the receiving cavity 31 from multiple outlets 35. The liquid can carry the dirt in the receiving cavity 31 out through the opening 32 to the outside of the sewage tank 30, so that the sewage tank 30 can be kept in a relatively clean state. The wastewater tank 30 can achieve a self-cleaning function by spraying liquid, eliminating the need for manual cleaning and effectively freeing up the user's hands, resulting in a better user experience.

[0154] Please see Figures 5 to 7 In the height direction H of the wastewater tank 30, a channel 33 is located at the top of the wastewater tank 30. The channel 33 allows liquid to enter and be sprayed from the outlet 35 towards the inner wall of the wastewater tank 30 in a direction away from the center of its cross-section. In some embodiments, the extended shape of the channel 33 includes arcuate, square arcuate, C-shaped, U-shaped, L-shaped, semi-circular, and annular shapes. Liquid entering the channel 33 is sprayed from the outlet 35 towards the inner wall of the wastewater tank 30 in a direction away from the center of its cross-section. When the extended shape of the channel 33 is annular, the channel 33 can be a closed structure. In this case, multiple outlets 35 can be distributed at any position around the circumference of the wastewater tank 30. After the liquid is sprayed into the receiving cavity 31 from the multiple outlets 35, the liquid can flow to various positions on the inner wall of the wastewater tank 30, thereby achieving a better cleaning effect on the wastewater tank 30. When the extended shape of channel 33 is arc-shaped, square arc-shaped, C-shaped, U-shaped, L-shaped, or semi-circular, channel 33 can be a non-closed structure. In this case, multiple outlets 35 are evenly or non-evenly distributed around the circumference of sewage tank 30 and spray liquid toward the inner wall of sewage tank 30.

[0155] In some embodiments, the length of the line segment connecting all the outlets 35 is not less than half the perimeter of the sewage tank 30, such as 1 / 2, 2 / 3, or 3 / 4 of the perimeter, or covering the outer perimeter of the sewage tank 30. The outlets 35 cover a large area, and the sprayed liquid covers a large area. Multiple outlets 35 are evenly or non-evenly distributed around the circumference of the sewage tank 30 and spray liquid toward the inner wall of the sewage tank 30.

[0156] Please see Figures 5 to 7 When external liquid enters channel 33 through inlet 331, outlet 35 allows the external liquid to enter the receiving cavity 31 and spray towards the inner wall of the wastewater tank 30. When external gas enters channel 33 through inlet 331, outlet 35 allows the external gas to enter the receiving cavity 31. In the height direction H of the wastewater tank 30, with outlet 35 located at the top of the wastewater tank 30, liquid is sprayed into the receiving cavity 31 through outlet 35. The liquid entering the receiving cavity 31 is sprayed towards the inner wall of the top of the wastewater tank 30 in a direction away from the center of the cross-section of the wastewater tank 30, and due to gravity, it flows downward along the inner wall of the wastewater tank 30. Thus, the liquid can carry the dirt on the inner wall of the wastewater tank 30 and flow out of the wastewater tank 30 through opening 32, resulting in a better cleaning effect for the wastewater tank 30. Since multiple outlets 35 are arranged circumferentially around the sewage tank 30, the outlets 35 can spray liquid in various directions onto the inner wall of the sewage tank 30, resulting in a larger cleaning range. In addition, when the liquid in the outlets 35 is sprayed toward the inner wall of the sewage tank 30 in a direction away from the center of the cross-section of the sewage tank 30, the distance from the liquid sprayed from the outlets 35 to the inner wall of the sewage tank 30 is shorter, and the splashing force of the liquid sprayed onto the inner wall of the sewage tank 30 is greater. The liquid can effectively wash away the dirt on the inner wall of the sewage tank 30, and the cleaning effect of the liquid on the inner wall of the sewage tank 30 is better. The multiple outlets 35 spraying liquid result in higher cleaning efficiency for the sewage tank 30.

[0157] The number of outlets 35 can be, but is not limited to, two, three, four, five, or more. When there are multiple outlets 35, they are spaced apart around the circumference of the wastewater tank 30. When liquid is simultaneously sprayed into the receiving cavity 31 from multiple outlets 35, the liquid can flow into various locations on the inner wall of the wastewater tank 30, thereby carrying away contaminants from the wastewater tank 30 and achieving a better cleaning effect.

[0158] The wastewater tank 30 of this application embodiment features a channel 33 and multiple outlets 35 at its top. These outlets 35 are spaced apart circumferentially around the wastewater tank 30. When cleaning is required, external liquid enters the channel 33 and is sprayed from the outlets 35 toward the inner wall of the wastewater tank 30 in a direction away from the center of its cross-section. This allows the external liquid to flush out contaminants from inside the tank. Compared to existing wastewater tanks 30, the wastewater tank 30 of this application achieves a self-cleaning function. The inner wall of the tank is sprayed with liquid, resulting in a large cleaning coverage area and high cleaning efficiency. Furthermore, the wastewater tank 30 requires no manual cleaning, providing a better user experience.

[0159] Please see Figure 6 and Figure 7In some embodiments, the top of the sewage tank 30 is provided with a water supply component 36, and the inner cavity of the water supply component 36 is a channel 33; along the direction away from the center of the cross-section of the sewage tank 30, the water supply component 36 includes a first side wall 361 and a second side wall 363 facing away from each other, the second side wall 363 facing the center of the cross-section of the sewage tank 30, and the outlet 35 is on the first side wall 361.

[0160] Specifically, when the wastewater tank 30 requires cleaning, the water supply component 36 allows external liquid to enter the wastewater tank 30 and spray it onto the inner wall of the wastewater tank 30. Outlets 35 are formed on the water supply component 36, and multiple outlets 35 can be evenly or non-evenly distributed on the water supply component 36. Preferably, the multiple outlets 35 are evenly distributed on the water supply component 36, allowing the liquid sprayed from the outlets 35 to flow into various locations on the inner wall of the wastewater tank 30, resulting in a better cleaning effect for the wastewater tank 30.

[0161] With the outlet 35 located on the first sidewall 361, the openings 32 of the multiple outlets 35 all face the inner wall of the wastewater tank 30. When liquid is sprayed from the outlets 35 into the receiving cavity 31, the liquid can be directly sprayed onto the inner wall of the wastewater tank 30. Furthermore, the liquid sprayed directly onto the inner wall of the wastewater tank 30 has a certain splashing force, thus effectively flushing away dirt from the inner wall of the wastewater tank 30 and preventing dirt from remaining on the inner wall of the wastewater tank 30.

[0162] Please see Figure 7 and Figure 8 In some embodiments, along the flow direction of the liquid in the channel 33, the outlet 35 includes a first surface and a second surface, the second surface being further away from the inlet 331 than the first surface, the second surface being an inclined surface, and the angle between the second surface and the flow direction of the liquid in the channel 33 being an acute angle.

[0163] In this application, since the channel 33 has only one inlet 331, when the inlet 331 is located in the middle of the channel 33 (excluding the two ends), the liquid entering the channel 33 from the inlet 331 can be divided into two streams flowing into the channel 33. The second surface of the outlet 35 away from the inlet 331 is an inclined surface. As the liquid flows from the channel 33 into the outlet 35, the liquid has forward inertia, so the liquid can flow out at an angle along the inclined surface of the outlet 35 and spray onto the inner wall of the sewage tank 30. When the liquid is sprayed at an angle onto the inner wall of the sewage tank 30, the liquid loses less kinetic energy during the flow, so the jet force of the liquid sprayed from the outlet 35 and splashed onto the inner wall of the sewage tank 30 is greater, and the liquid splashed onto the inner wall of the sewage tank 30 can effectively wash away the dirt on the inner wall of the sewage tank 30. Furthermore, the liquid sprayed from multiple outlets 35 can basically flow through all positions of the inner wall of the sewage tank 30, resulting in a better cleaning effect of the sewage tank 30. If the second surface of the outlet 35 is perpendicular to the flow direction of the liquid in the channel 33, the flow direction of the liquid changes significantly when it flows into the outlet 35, resulting in a large loss of kinetic energy. The jet force of the liquid ejected from the outlet 35 onto the inner wall of the wastewater tank 30 is relatively small, leading to poor flushing effect and a poor cleaning effect on the inner wall of the wastewater tank 30.

[0164] Please see Figure 7 and Figure 8 In some embodiments, the first surface is also an inclined surface, the angle between the first surface and the flow direction of the liquid in the channel 33 is an obtuse angle, and the outlet 35 is a gradually expanding through hole.

[0165] In the case where the outlet 35 is a gradually expanding through-hole, the liquid loses less kinetic energy during flow, resulting in a greater jet force of liquid ejected from the outlet 35 and splashed onto the inner wall of the sewage tank 30. This effectively washes away dirt from the inner wall of the sewage tank 30. Liquid ejected from multiple outlets 35 can flow through virtually all areas of the inner wall of the sewage tank 30, resulting in good cleaning performance. Furthermore, the gradually expanding through-hole design simplifies the machining of the water supply component 36, improving its processing efficiency.

[0166] Please see Figures 6 to 8 In one embodiment, the water supply component 36 is a protruding structure extending from the top of the wastewater tank 30 into the receiving cavity 31. The inner cavity of the protruding structure is a channel 33. Because the protruding structure protrudes into the receiving cavity 31, the opening 32 of the outlet 35 can face the inner wall of the wastewater tank 30. Liquid in the channel 33 is sprayed from the outlet 35 towards the inner wall of the wastewater tank 30 in a direction away from the center of its cross-section, resulting in a better cleaning effect on the wastewater tank 30.

[0167] Please see Figure 7 and Figure 8 In some embodiments, the water supply component 16 may be a closed annular structure. In this case, the channel 33 is a closed channel 33. When multiple outlets 35 are evenly distributed in the water supply component, the liquid sprayed from the multiple outlets 35 toward the inner wall of the wastewater tank 30 can flow to various positions on the inner wall of the wastewater tank 30. The liquid can carry the dirt from various positions on the inner wall of the wastewater tank 30 and flow out of the wastewater tank 30 through the connection hole 32, resulting in a better cleaning effect for the wastewater tank 30. In other embodiments, the water supply component is an annular structure that can be at least partially opened. In this case, the channel 33 is an open channel 33. When the water supply component is an annular structure that is at least partially open, other components can be installed in the open position of the water supply component, and the structure of the top of the wastewater tank 30 is more compact.

[0168] Please see Figure 5 , Figure 6 , Figure 7 and Figure 9 In some embodiments, the sewage tank 30 includes a tank body 37, which forms a receiving cavity 31; a water supply component 36 extends from the inner wall of the tank body 37 toward the receiving cavity 31, and the water supply component 36 includes a first component 365 and a second component 367. The first component 365 is connected to the inner wall of the tank body 37, and the second component 367 is bent and connected to the first component 365 and spaced apart from the inner wall of the tank body 37. An outlet 35 is provided in the second component 367.

[0169] Specifically, when the sewage tank 30 only includes the tank body 37, the structure of the sewage tank 30 is relatively simple, and the processing of the sewage tank 30 is relatively easy. In this case, the receiving cavity 31 can be an open or closed cavity. The first component 365 can be connected to the inner wall of the tank body 37 circumferentially, and the first component 365 can be a ring structure. The second component 367 is connected to the first component 365, and the second component 367 can also be a ring structure. The ring shape of the first component 365 can be the same as the cross-sectional shape of the tank body 37, so that the first component 365 can be stably connected to the inner wall of the tank body 37. The inner cavity of the first component 365 is a first sub-channel 33, and the inner cavity of the second component 367 is a second sub-channel 33. The first sub-channel 33 and the second sub-channel 33 are connected and together form channel 33. When the sewage tank 30 needs to be cleaned, external liquid flows into the first sub-channel 33 from the inlet 331 and flows through the second sub-channel 33 and is sprayed onto the inner wall of the sewage tank 30 from the outlet 35.

[0170] Please see Figure 5 and Figure 9The included angle between the first component 365 and the second component 367 can range from 0° to 180°. Preferably, the included angle between the first component 365 and the second component 367 can be 90° or approximately 90°. In this case, the opening 32 of the outlet 35 can be directly opposite the inner wall of the sewage tank 30. The liquid sprayed from the outlet 35 toward the inner wall of the sewage tank 30 has a certain splashing force, so that the liquid can effectively wash away the dirt on the inner wall of the sewage tank 30 and prevent dirt from remaining on the inner wall of the sewage tank 30.

[0171] The first component 365 can be connected to the inner wall of the top of the tank 37, and the second component 367 is connected to the first component 365. In the height direction H of the sewage tank 30, the second component 367 extends from the top of the tank 37 towards the bottom of the tank 37. In one embodiment, the length of the second component 367 can be relatively short; for example, in the height direction H of the sewage tank 30, the length of the second component 367 can be less than half the height of the tank 37. In this case, less material is used for the second component 367, saving material costs. Multiple outlets 35 can be distributed at any position on the second component 367 in the height direction H of the sewage tank 30. When liquid is sprayed from the outlets 35 onto the inner wall of the top of the sewage tank 30, the liquid can flow downwards from the top of the tank 37 due to gravity. The liquid can carry away dirt from the inner wall of the sewage tank 30 and flow out of the sewage tank 30 through the opening 32, thus keeping the sewage tank 30 relatively clean. In another embodiment, the second component 367 can be relatively long; for example, in the height direction H of the wastewater tank 30, the length of the second component 367 can be greater than half the height of the tank body 37. In the height direction H of the wastewater tank 30, multiple outlets 35 can be distributed at any position on the second component 367. In this case, in the height direction H of the wastewater tank 30, the liquid sprayed from the outlets 35 can reach more areas of the inner wall of the wastewater tank 30, resulting in a larger area of ​​the inner wall of the wastewater tank 30 splashed with liquid, thus achieving a better cleaning effect on the wastewater tank 30.

[0172] Please see Figures 5 to 7 In some embodiments, the sewage tank 30 includes a combined cover 39 and a tank 37, which together form a receiving cavity 31. The cover 39 includes a first side 391 and a second side 393 facing away from each other. The first side 391 of the cover 39 faces into the receiving cavity 31. A water supply component 36 is provided on the first side 391 of the cover 39, and the water supply component 36 is spaced apart from the inner wall of the tank 37.

[0173] Specifically, the cover 39 and the housing 37 are connected detachably or non-detachably. 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, adhesive bonding, interference fits, or ultrasonic welding. Preferably, the cover 39 and the housing 37 are detachably connected. In this case, if the cover 39 or the housing 37 is damaged, it is easy to remove the cover 39 or the housing 37 for repair.

[0174] When the receiving cavity 31 is jointly enclosed by the cover 39 and the box body 37, the receiving cavity 31 can be a closed cavity. In this case, when the sewage tank 30 moves or rotates, the dirt or liquid in the receiving cavity 31 will not flow out. In the height direction H of the sewage tank 30, the first side 391 of the cover 39 is the lower side, and the second side 393 of the cover 39 is the upper side. The water supply component 36 of the first side 391 of the cover 39 has a ring structure, and the shape of this ring structure can be similar to the cross-section of the sewage tank 30. When multiple outlets 35 are distributed in the water supply component 36, liquid can be sprayed from the multiple outlets 35 towards various positions on the inner wall of the sewage tank 30, and the cleaning effect of the sewage tank 30 is better.

[0175] Please see Figures 5 to 7 In some embodiments, the first side 391 of the cover 39 is further provided with a separator 395 and a liquid inlet structure 397. The separator 395 is connected to the inner wall of the cover 39 to divide the first side 391 of the cover 39 into a first zone 3911 and a second zone 3913. The water supply component 36 is located in the first zone 3911. The first zone 3911 and the box 37 together form a receiving cavity 31. One end of the liquid inlet structure 397 is located in the first zone 3911 and communicates with the water supply component 36, and the other end is located in the second zone 3913 and is provided with an inlet 331.

[0176] The liquid inlet structure 397 is used to guide external liquid into the water supply component 36. The inner cavity of the liquid inlet structure 397 and the inner cavity of the water supply component 36 are connected and can jointly form a channel 33. The inlet 331 of the channel 33 is opened in the liquid inlet structure 397, and the inlet 331 is used to allow external liquid to enter the channel 33. The liquid inlet structure 397 and the water supply component 36 can be an integral structure or separate structures. When the liquid inlet structure 397 and the water supply component 36 are an integral structure, the liquid inlet structure 397 and the water supply component 36 can be integrally formed. When the liquid inlet structure 397 and the water supply component 36 are separate structures, the liquid inlet structure 397 and the water supply component 36 can be detachably or non-detachably connected.

[0177] The separator 395 divides the first side 391 of the cover 39 into a first zone 3911 and a second zone 3913, with the first zone 3911 and the second zone 3913 separated. The receiving cavity 31 formed by the first zone 3911 and the housing 37 can be a closed cavity, so that liquid and dirt in the receiving cavity 31 do not easily flow out from between the cover 39 and the housing 37. The liquid inlet structure 397 located in the second zone 3913 can communicate with other external components to guide external liquid to the water supply component 36. The separator 395 and the side wall of the cover 39 can be an integral structure or a separate structure. When the separator 395 and the side wall of the cover 39 are an integral structure, the separator 395 and the side wall of the cover 39 can be integrally formed. When the separator 395 and the side wall of the cover 39 are a separate structure, the separator 395 and the side wall of the cover 39 can be detachably or non-detachably connected. The material of the separator 395 can be the same as the material of the side wall of the cover 39, or the material of the separator 395 can be different from the material of the side wall of the cover 39.

[0178] Please see Figure 5 and Figure 6 Furthermore, in some embodiments, the cover 39 includes a first cover 398 and a second cover 399, which are detachably connected and together form a channel 33.

[0179] The first cover 398 is connected to the second cover 399, and the second cover 399 is connected to the housing 37. The first cover 398 and the second cover 399 together form a channel 33, and the second cover 399 and the housing 37 together form a receiving cavity 31. The detachable installation methods between the first cover 398 and the second cover 399 include, but are not limited to, threaded connection, screw connection, or snap-fit ​​connection.

[0180] The shape of the first cover 398 can be approximately the same as that of the channel 33, and the width of the first cover 398 is greater than or equal to the width of the channel 33. Therefore, when the first cover 398 and the second cover 399 together enclose the channel 33, less material is needed for the first cover 398, saving material costs. With the first cover 398 and the second cover 399 detachably connected, cleaning the channel 33 is convenient. After the wastewater tank 30 has been used for a period of time, the first cover 398 can be removed from the second cover 399, and the channel 33 can be cleaned to keep the interior of the channel 33 relatively clean. When liquid enters the channel 33 from the inlet 331 and is sprayed from the channel 33 through the outlet 35 onto the inner wall of the wastewater tank 30, the liquid will not carry dirt from the channel 33 into the wastewater tank 30, resulting in a good cleaning effect for the wastewater tank 30.

[0181] Please see Figures 5 to 7In some embodiments, the air pump assembly 60 includes a first air pump 61, and the sewage tank 30 is further provided with a first air hole 34. One end of the first air hole 34 is connected to the receiving cavity 31, and the other end is connected to the first air pump 60. When the receiving cavity 31 stores sewage, the power system 20 is in a first state, and the first air pump 60 is used to extract gas from the receiving cavity 31 through the first air hole 34. When the stored sewage is discharged from the receiving cavity 31, and the outlet 35 sprays liquid into the receiving cavity 31, the power system 20 is in a first state, and the first air pump 60 is used to extract gas from the receiving cavity 31 through the first air hole 34.

[0182] Specifically, the first air vent 34 is connected to the first air pump 60, and the first air vent 34 is used to allow gas from the receiving cavity 31 to flow into the first air pump 60. When the cleaning module 200 is cleaning the surface to be cleaned, the dirt on the mopping member 203 is scraped off by the scraper member 15, and the scraped dirt enters the wastewater tank 30 and is stored in the wastewater tank 30. Since the receiving cavity 31 is a closed cavity, when the first air pump 60 draws gas from the receiving cavity 31 through the first air vent 34, the receiving cavity 31 is under negative pressure. The air pressure inside the receiving cavity 31 is lower than the air pressure outside the receiving cavity 31, and the dirt scraped off by the scraper member 15 is squeezed into the receiving cavity 31 and stored in the receiving cavity 31. When dirt enters the receiving cavity 31, the first air pump 60 can stop drawing gas from the receiving cavity 31. The receiving cavity 31 can be maintained in a negative pressure state, and the dirt can be stably stored in the receiving cavity 31, thereby preventing the problem of dirt flowing from the receiving cavity 31 to the surface to be cleaned.

[0183] After the waste in the wastewater tank 30 is discharged to the designated location, the wastewater tank 30 needs to be cleaned. External liquid enters the channel 33 through the inlet 331 and is sprayed onto the inner wall of the wastewater tank 30 through the outlet 35. At this time, the first air pump 60 draws gas from the receiving cavity 31 through the first air hole 34, creating a negative pressure inside the receiving cavity 31. The air pressure inside the receiving cavity 31 is lower than the air pressure outside the receiving cavity 31, making it difficult for the liquid entering the receiving cavity 31 to flow out of the wastewater tank 30, and the liquid will be stored in the receiving cavity 31. The liquid in the channel 33 is continuously sprayed onto the inner wall of the wastewater tank 30 through the outlet 35, thereby continuously increasing the amount of liquid stored in the receiving cavity 31. When the receiving cavity 31 is full of liquid, the external liquid supply to the channel 33 stops, and the liquid stops spraying onto the inner wall of the wastewater tank 30. At this time, the first air pump 60 can stop drawing gas from the receiving cavity 31, and the receiving cavity 31 can be maintained at a negative pressure. The liquid stored in the receiving cavity 31 can then soak the inner wall of the sewage tank 30. Since the receiving cavity 31 is filled with liquid, the liquid can soak all parts of the inner wall of the sewage tank 30. When the inner wall of the sewage tank 30 is soaked with liquid, the liquid can dissolve the dirt on the inner wall of the sewage tank 30, thus the liquid has a better cleaning effect on the sewage tank 30.

[0184] Please see Figures 5 to 7 In some embodiments, when the waste in the receiving cavity 31 is discharged from the sewage tank 30, the power system 20 is in a second state, and the first air pump 60 is used to pump air into the receiving cavity 31 through the first air hole 34.

[0185] The liquid sprayed into the receiving cavity 31 through the outlet 35 dissolves the dirt on the inner wall of the sewage tank 30 after soaking it for a period of time. Once the liquid has dissolved the dirt, it can carry the dirt out of the sewage tank 30 through the opening 32. At this time, the first air pump 60 switches from drawing gas from the receiving cavity 31 to pumping air into the receiving cavity 31. The first air hole 34 is connected to the first air pump 60 and is used to allow gas from the first air pump 60 to enter the receiving cavity 31. When the first air pump 60 pumps air into the receiving cavity 31 through the first air hole 34, the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31, thus allowing the liquid in the receiving cavity 31 to carry the dirt out through the opening 32 to the outside of the sewage tank 30. Furthermore, when the first air pump 60 pumps air into the receiving cavity 31, all the liquid and dirt in the receiving cavity 31 can be discharged outside the sewage tank 30, leaving no residual liquid and dirt in the sewage tank 30, thus achieving a better cleaning effect for the sewage tank 30.

[0186] When the first air pump 60 pumps air into the receiving cavity 31 to discharge liquid and waste from the sewage tank 30, the connecting pipe 13 can be a straight pipe, and may also include a bend 133. When the connecting pipe 13 includes a bend 133, the highest point of the bend 133 is higher than the opening 32 in the height direction H of the sewage tank 30. When the first air pump 60 does not pump air into the receiving cavity 31, liquid and waste in the receiving cavity 31 are difficult to discharge through the bend 133 to the outside of the sewage link 10, thus preventing liquid and waste from flowing onto the surface to be cleaned. When liquid and waste in the receiving cavity 31 need to be discharged, the first air pump 60 pumps air into the receiving cavity 31, and the liquid and waste can overcome the height of the bend 133 when flowing into the connecting pipe 13, allowing the liquid and waste to be discharged outside the sewage link 10.

[0187] In other embodiments, when liquid and waste in the receiving cavity 31 need to be discharged from the wastewater tank 30, the receiving cavity 31 can be connected to the atmosphere, so that the air pressure inside the receiving cavity 31 is the same as the atmospheric pressure, and the liquid and waste in the receiving cavity 31 can flow out of the wastewater tank 30 through the opening 32. The method of liquid and waste flowing out of the wastewater tank 30 from the receiving cavity 31 is relatively simple. At this time, the connecting pipe 13 of the cleaning module 200 can be a straight pipe, and the connecting pipe 13 is connected to the opening 32, so that the liquid and waste in the receiving cavity 31 can flow out of the wastewater link 10 through the connecting pipe 13.

[0188] At this time, when the power system 20 is in the first state, the first air pump 60 is used to extract gas from the receiving cavity 31. When the power system 20 is in the second state, the first air pump 60 is used to pump air into the receiving cavity 31. When the first air pump 60 is used to extract gas from the receiving cavity 31 and also to pump air into the receiving cavity 31, the structure of the air pump assembly 60 is relatively simple, and the number of components in the air pump assembly 60 is small, which can save costs. When the first air hole 34 is used to allow gas from the receiving cavity 31 to flow into the first air pump 60, and the first air hole 34 is also used to allow gas from the first air pump 60 to enter the receiving cavity 31, the structure of the sewage tank 30 is relatively simple, and the processing of the sewage tank 30 is relatively easy.

[0189] Please see Figures 5 to 7 In some embodiments, the sewage tank 30 is also provided with a second vent spaced apart from the first vent 34, and the second vent is connected to the receiving cavity 31; when the sewage in the receiving cavity 31 is discharged from the sewage tank 30, the power system 20 is in a second state, and the first air pump 60 is used to pump air into the receiving cavity 31 through the second vent.

[0190] One end of the second vent is connected to the receiving cavity 31, and the other end is connected to the first air pump 60. The second vent is used to allow gas from the first air pump 60 to enter the receiving cavity 31. When the first air pump 60 pumps air into the receiving cavity 31 through the second vent, the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31. As a result, the liquid inside the receiving cavity 31 can carry the dirt out through the opening 32 to the outside of the sewage tank 30. Furthermore, when the first air pump 60 pumps air into the receiving cavity 31, all the liquid and dirt inside the receiving cavity 31 can be discharged to the outside of the sewage tank 30, leaving no residual liquid or dirt in the sewage tank 30, thus achieving a better cleaning effect for the sewage tank 30.

[0191] With the first vent 34 used to allow gas from the receiving cavity 31 to flow into the first air pump 60, and the second vent used to allow gas from the first air pump 60 to enter the receiving cavity 31, the first and second vents do not interfere with each other, thus improving the working efficiency of the first air pump 60 (the efficiency of extracting gas from the receiving cavity 31 and the efficiency of pumping gas into the receiving cavity 31). Furthermore, if the first vent 34 is damaged, it will not affect the function of the second vent. Similarly, if the second vent is damaged, it will not affect the function of the first vent 34, resulting in good stability and reliability of the wastewater tank 30.

[0192] Please see Figures 5 to 7In some embodiments, the air pump assembly 60 further includes a second air pump, and the sewage tank 30 is also provided with a second air hole spaced apart from the first air hole 34. One end of the second air hole is connected to the receiving cavity 31, and the other end is connected to the second air pump. When the sewage in the receiving cavity 31 is discharged from the sewage tank 30, the power system 20 is in a second state, and the second air pump is used to pump air into the receiving cavity 31 through the second air hole.

[0193] When liquid is sprayed into the receiving cavity 31 through the outlet 35, the first air pump 60 draws gas from the receiving cavity 31 through the first air hole 34, so that the liquid is stored in the receiving cavity 31 and can soak the inner wall of the sewage tank 30. A second air pump is disposed on the main body 201 and spaced apart from the first air pump 60. When the liquid dissolves the dirt on the inner wall of the sewage tank 30, the second air pump can pump air into the receiving cavity 31 through the second air hole. When the second air pump pumps air into the receiving cavity 31 through the second air hole, the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31, so that the liquid in the receiving cavity 31 can carry the dirt out of the sewage tank 30. Furthermore, when the second air pump pumps air into the receiving cavity 31, all the liquid and dirt in the receiving cavity 31 can be discharged out of the sewage tank 30, leaving no residual liquid or dirt in the sewage tank 30, thus achieving a better cleaning effect for the sewage tank 30.

[0194] When the power system 20 is in its first state, the first air pump 60 is used to extract gas from the receiving cavity 31. When the power system 20 is in its second state, the second air pump is used to pump air into the receiving cavity 31. With both the first air pump 60 extracting gas from the receiving cavity 31 and the second air pump pumping air into it, the second air pump can quickly start and pump air into the receiving cavity 31 when liquid and waste need to be discharged from the wastewater tank 30. The first air pump 60 does not need to switch from extraction to pumping; the use of the second air pump saves the time required for this switching process, allowing liquid and waste to be quickly discharged from the opening 32 to the outside of the wastewater tank 30. Furthermore, the division of labor between the first and second air pumps is clear, and both have a long service life.

[0195] In some embodiments, the sewage link 10 further includes a discharge component 50, which has a discharge channel 51. The discharge component 50 is connected to the second opening 113 of the sewage channel 11, and the discharge channel 51 is used to discharge the sewage in the sewage channel 11 to the outside of the sewage link 10.

[0196] Please see Figure 1 and Figure 2When the receiving cavity 31 is filled with dirt or the cleaning module 200 has finished cleaning the surface to be cleaned, the cleaning device 1000 can be moved to the drain position to discharge the dirt in the receiving cavity 31. The drain component 50 is used to discharge the dirt in the receiving cavity 31 to the outside of the sewage link 10. When external liquid enters the sewage tank 30 to clean the sewage tank 30, the drain component 50 is also used to discharge the liquid and dirt in the sewage tank 30 and the sewage link 10 to the outside of the sewage link 10. The drain channel 51 is used to allow the liquid and dirt flowing into the drain channel 51 from the sewage channel 11 to flow out to the outside of the sewage link 10. At this time, the liquid flowing into the drain channel 51 can also clean the drain component 50, so that the drain component 50 will not accumulate too much dirt. The drain component 50 is detachably or non-detachably connected to the sewage channel 11. The material of the drain component 50 can be, but is not limited to, metal or plastic. When the drain component 50 is made of metal, the drain component 50 has high strength, good wear resistance, and long service life. When the drain component 50 is made of plastic, it is lightweight and has a lower cost.

[0197] Please see Figure 1 and Figure 10 In some embodiments, when the external force on the outside of the drain channel 51 changes, the drain component 50 can remain in a non-drained state ( Figure 1 (as shown) and sewage discharge status ( Figure 10 Switch between (as shown).

[0198] At this time, an element can be installed on the outside of the drain channel 51 to apply external force to the drain component 50, so that the drain component 50 switches between a non-drained state and a drained state. The outside of the drain channel 51 refers to all outer surfaces (including the outer side surface and outer end surface) of the drain component 50.

[0199] No other components are required inside the drainage channel 51, allowing waste to flow out smoothly and preventing blockages caused by internal components. The external force acting on the outside of the drainage channel 31 refers to any force acting on the outside of the drainage channel 31, and the source of this force is unrestricted. This force can originate 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.

[0200] The sewage discharge component 50 being in an undischarged state means that the sewage in the receiving cavity 31 cannot flow out of the sewage discharge channel 51 to the outside of the sewage link 10. The sewage discharge component 50 being in a discharged state means that the sewage in the receiving cavity 31 can flow out of the sewage discharge channel 51 to the outside of the sewage link 10.

[0201] In this application, since the force that changes the discharge state and non-discharge state of the drain component 50 is on the outside of the drain channel 51, the drain component 50 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 51. This is smoother than the prior art where a valve is placed in the drain channel 51, and it is more effective in preventing the drain channel 51 from getting blocked.

[0202] When the cleaning device 1000 is cleaning the surface to be cleaned, the dirt from the mopping component 203 enters the receiving cavity 31. At this time, the drain component 50 is in an undrained state, and the dirt in the receiving cavity 31 cannot flow out through the drain channel 51, thus preventing the problem of dirt flowing from the drain channel 51 to the surface to be cleaned. When the cleaning device 1000 needs to drain, the drain component 50 is in a draining state, and the dirt in the receiving cavity 31 can pass through the drain channel 51 and flow out to the outside of the wastewater link 10.

[0203] In another embodiment, the external force on the drain component 50 when it is in the draining state is greater than the external force on the drain component 50 when it is in the non-draining state.

[0204] Please see Figure 15 and Figure 16 In one embodiment, when the sewage channel 51 is subjected to force on the outside (e.g.) Figure 16 As shown), the drain component 50 is in the draining state. When there is no force on the outside of the drain channel 51 (e.g.) Figure 15 As shown, the drain component 50 is in an undrained state. When the cleaning module 200 is cleaning the surface to be cleaned, the drain component 50 is not under force and is in an undrained state, so the dirt in the receiving cavity 31 cannot be discharged through the drain channel 51 to the outside of the sewage link 10. When the cleaning module 200 needs to drain, the drain component 50 is subjected to external force, and the drain component 50 switches from the undrained state to the drained state, so that the dirt in the receiving cavity 31 can be discharged from the drain channel 51 to the outside of the sewage link 10.

[0205] In another embodiment, when force is applied to the outside of the drain channel 51, the drain component 50 is in a non-drained state. When no force is applied to the outside of the drain channel 51, the drain component 50 is in a drained state. When the cleaning module 200 is cleaning the surface to be cleaned, the drain component 50 is under force and is in a non-drained state, so that the dirt in the receiving cavity 31 cannot be discharged from the drain channel 51 to the outside of the sewage link 10. When the cleaning module 200 needs to drain, the drain component 50 is not under force, and the drain component 50 switches from a non-drained state to a drained state, so that the dirt in the receiving cavity 31 can be discharged from the drain channel 51 to the outside of the sewage link 10.

[0206] In another embodiment, the external force on the drain component 50 when it is in a non-draining state is greater than the external force on the drain component 50 when it is in a draining state.

[0207] The cleaning module 200 of this application switches the drain component 50 between a draining state and a non-draining state by applying external force to the outside of the drain channel 51. When the cleaning module 200 needs to drain, the drain component 50 can be in the draining state, so that the dirt in the sewage tank 30 can be discharged outside the cleaning module 200. Compared with the current drain component 50, the drain channel 51 of the drain component 50 of this application does not need to be equipped with a valve, so the drain channel 51 is not easy to be blocked, and the dirt flows out of the drain channel 51 more smoothly.

[0208] Please see Figure 1 and Figure 10 In some embodiments, the outlet of the sewage discharge channel 51 is a sewage outlet 511, and the height of the sewage outlet 511 can be varied when the external force changes. Specifically, in some embodiments, the sewage discharge component 50 can rotate relative to the sewage tank 30 to switch between a non-discharged state and a discharged state. When the sewage discharge component 50 is in the discharged state, the height of the sewage outlet 511 is lower than the height of the sewage outlet 511 when the sewage discharge component 50 is in the non-discharged state.

[0209] The drain outlet 511 is used to allow sewage in the sewage channel 51 to flow out to the outside of the sewage link 10. The drain component 50 is rotatably mounted on the body 201, and can rotate relative to the sewage tank 30 when the external force on the outside of the sewage channel 51 changes. During the rotation of the drain component 50, the height of the drain outlet 511 changes in the height direction H of the sewage tank 30. Due to gravity, the sewage in the sewage tank 30 flows to a lower position. When the height of the drain outlet 511 is lower, the sewage in the receiving cavity 31 can pass through the sewage channel 51 and flow out from the drain outlet 511, thus putting the drain component 50 in a draining state. When the height of the drain outlet 511 is higher, the sewage in the receiving cavity 31 enters the sewage channel 51 and is difficult to flow out from the drain outlet 511, thus putting the drain component 50 in a non-draining state.

[0210] When the cleaning module 200 is cleaning the surface to be cleaned, under the action of external force, the drain component 50 can rotate relative to the wastewater tank 30 to raise the height of the drain port 511, making it difficult for dirt to flow out of the drain port 511. At this time, the drain component 50 is in the non-draining state. When the cleaning module 200 needs to drain, under the action of external force, the drain component 50 can rotate relative to the wastewater tank 30 to lower the height of the drain port 511, allowing dirt in the drain channel 51 to flow out of the drain port 511. At this time, the drain component 50 is in the draining state. The drain component 50 switches between the draining state and the non-draining state by rotating, and the flow of dirt from the drain channel 51 is relatively smooth, and there is no problem of blockage inside the drain channel 51.

[0211] Please see Figure 1 and Figure 10 In some embodiments, the sewage discharge channel 51 includes a sewage inlet 513, which is connected to the sewage channel 11. When the sewage discharge component 50 is not in a sewage discharge state, the sewage inlet 513 is lower than the sewage outlet 511 in the height direction H of the sewage tank 30. When the sewage discharge component 50 is in a sewage discharge state, the sewage inlet 513 is flush with the sewage outlet 511 or higher than the sewage outlet 511 in the height direction H of the sewage tank 30.

[0212] The inlet 513 is used to allow waste from the sewage channel 11 to enter the outlet 51. The inlet 513 is located at the end where the outlet 50 connects to the sewage channel 11. During the rotation of the outlet 50 relative to the sewage tank 30, the height of the inlet 513 remains constant in the height direction H of the sewage tank 30. The outlet 511 is located at the free end of the outlet 50, and its height varies in the height direction H of the sewage tank 30 during the rotation of the outlet 50 relative to the sewage tank 30.

[0213] When the cleaning module 200 is cleaning the surface to be cleaned, under the action of external force, the drain component 50 can rotate relative to the sewage tank 30 so that the drain outlet 511 is higher than the inlet 513. After the dirt in the sewage channel 11 enters the drain channel 51 from the inlet 513, due to gravity, the dirt cannot flow to the higher drain outlet 511, so the dirt cannot flow out of the drain outlet 511 to the outside of the sewage link 10. At this time, the drain component 50 is in an undrained state. When the cleaning module 200 needs to drain, under the action of external force, the drain component 50 can rotate relative to the sewage tank 30 so that the drain outlet 511 is lower than the inlet 513, or so that the drain outlet 511 is flush with the inlet 513. After the dirt in the sewage channel 11 enters the drain channel 51 from the inlet 513, due to gravity, the dirt can quickly flow out of the drain outlet 511 to the outside of the sewage link 10. At this time, the drain component 50 is in a draining state.

[0214] In some embodiments, the drain component 50 is connected to the sewage tank 30 via the sewage channel 11. In its natural state (i.e., without external force), the drain outlet 511 of the drain component 50 is higher than the inlet 513 to ensure that the drain component 50 is in a non-drained state. However, when subjected to external force on the outside of the sewage channel 51, the height of the drain outlet 513 of the drain component 50 can be changed, allowing the drain outlet 511 to be lower than or level with the inlet 513, ensuring that the drain component 50 is in a draining state. Considering practical use, since the drain component 50 is in a non-drained state most of the time, setting the natural state of the drain component 50 to a non-drained state, meaning that no external force is required on the drain component 50 in the non-drained state, and external force is only applied to the drain component 50 in the draining state, simplifies the entire control process, simplifies the structure, and improves the reliability of the water system 100.

[0215] Please see Figure 1 and Figure 10 In some embodiments, the sewage discharge channel 51 is always open in both the sewage discharge state and the non-sewage discharge state of the sewage discharge component 50. In this case, when the sewage discharge component 50 switches from the non-sewage discharge state to the sewage discharge state, that is, when the sewage discharge component 50 rotates so that the sewage discharge port 511 is lower than the sewage inlet port 513, the waste in the receiving cavity 31 can quickly flow out of the sewage discharge channel 51 to the outside of the sewage link 10. The sewage discharge channel 51 remains open throughout the switching between the sewage discharge state and the non-sewage discharge state; that is, the sewage discharge channel 51 is always open in both the sewage discharge state and the non-sewage discharge state. This eliminates the need for valves or other structures in the sewage discharge channel 51, thus preventing hair and other waste from getting stuck and causing blockage. For the sewage discharge channel 51 that is always open, the height of the sewage discharge port 511 is controlled to ensure that waste in the sewage tank 30 does not flow out in the non-sewage discharge state.

[0216] If the sewage discharge channel 51 is connected to the sewage tank 30 through the sewage channel 11, in the state of no sewage discharge, the height of the sewage outlet 511 of the sewage discharge channel 51 is higher than the sewage inlet 513; furthermore, the height of the sewage outlet 511 is higher than the top of the sewage channel 11.

[0217] Please see Figure 1 and Figure 10In some embodiments, when the drain component 50 is in a non-draining state, the angle between the central axis of the drain outlet 511 of the drain component 50 extending away from the drain inlet 513 and the height direction from the bottom to the top of the sewage tank 30 is zero or an acute angle; when the drain component 50 is in a draining state, the angle between the central axis of the drain outlet 511 of the drain component 50 extending away from the drain inlet 513 and the height direction from the bottom to the top of the sewage tank 30 is greater than or equal to 90°.

[0218] Specifically, when the sewage discharge component 50 is not in a sewage discharge state, the angle between the central axis of the sewage discharge port 511 extending towards the sewage inlet 513 away from the sewage discharge component 50 and the height direction from the bottom to the top of the sewage tank 30 ranges from [0°, 90°]. For example, the angle between the central axis of the sewage discharge port 511 extending towards the sewage inlet 513 away from the sewage discharge component 50 and the height direction from the bottom to the top of the sewage tank 30 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 30, the sewage discharge port 511 of the sewage discharge channel 51 is higher than the sewage inlet 513, making it difficult for sewage to flow out from the sewage discharge port 511.

[0219] When the drain 50 is in the draining state, the angle between the central axis of the drain outlet 511 extending away from the drain outlet 513 and the height direction from the bottom to the top of the sewage tank 30 ranges from [90°, 180°]. For example, the angle between the central axis of the drain outlet 511 extending away from the drain outlet 513 and the height direction from the bottom to the top of the sewage tank 30 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 511 extending away from the drain outlet 513 and the height direction from the bottom to the top of the sewage tank 30 is 90°, the drain outlet 513 and the drain outlet 511 are flush in the height direction H of the sewage tank 30. When the angle between the central axis of the drain outlet 511 extending away from the drain inlet 513 and the height direction from the bottom to the top of the sewage tank 30 is greater than 90°, the drain outlet 511 is lower than the drain inlet 513 in the height direction H of the sewage tank 30. When the drain outlet 511 is higher than the drain inlet 513 or flush with the drain inlet 513 in the height direction H of the sewage tank 30, the sewage entering the sewage channel 51 from the drain inlet 513 can flow out from the drain outlet 511, so that the sewage in the sewage tank 30 can be quickly discharged to the outside of the sewage link 10.

[0220] Please see Figure 1 and Figure 10 In some embodiments, when the drain component 50 is subjected to an external force, the drain component 50 rotates relative to the sewage tank 30 in a first direction to switch from a non-drained state to a drained state; when the external force on the drain component 50 disappears, the drain component 50 rotates relative to the sewage tank 30 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.

[0221] Specifically, the rotation of the sewage discharge component 50 relative to the sewage tank 30 in the first direction means that, in the height direction H of the sewage tank 30, the height of the sewage inlet 513 remains unchanged, while the height of the sewage outlet 511 gradually decreases. The rotation of the sewage discharge component 50 relative to the sewage tank 30 in the second direction means that, in the height direction H of the sewage tank 30, the height of the sewage inlet 513 remains unchanged, while the height of the sewage outlet 511 gradually increases.

[0222] When the cleaning module 200 needs to discharge wastewater, the side wall of the discharge component 50 can be subjected to external force, allowing the discharge component 50 to rotate in a first direction. When the discharge component 50 rotates in the first direction, the height of the discharge port 511 gradually decreases in the height direction H of the wastewater tank 30. When the angle between the central axis of the discharge port 511 extending away from the inlet port 513 and the height direction from the bottom to the top of the wastewater tank 30 is within the range of [90°, 180°], that is, in the height direction H of the wastewater tank 30, the discharge port 511 is lower than the inlet port 513, or the discharge port 511 is flush with the inlet port 513, so that wastewater entering the discharge channel 51 from the inlet port 513 can flow out from the discharge port 511, at which point the discharge component 50 is in a discharge state. When the discharge component 50 is in a discharge state, wastewater in the wastewater tank 30 can be quickly discharged from the discharge channel 51 to the outside of the wastewater link 10.

[0223] When the cleaning module 200 has completed its sewage discharge, the external force on the side wall of the sewage discharge component 50 disappears, allowing the sewage discharge component 50 to rotate in the second direction. As the sewage discharge component 50 rotates in the second direction, the height of the sewage outlet 511 gradually increases in the height direction H of the sewage tank 30. When the angle between the central axis of the sewage outlet 511 extending away from the sewage inlet 513 and the height direction from the bottom to the top of the sewage tank 30 is within the range of [0°, 90°], that is, in the height direction H of the sewage tank 30, the sewage outlet 511 is higher than the sewage inlet 513. Therefore, dirt entering the sewage discharge channel 51 from the sewage inlet 513 is difficult to flow out of the sewage outlet 511, and the sewage discharge component 50 is in a non-discharged state. When the sewage discharge component 50 is in a non-discharged state, dirt in the sewage tank 30 will not flow to the surface to be cleaned.

[0224] Please see Figure 1 and Figure 10In some embodiments, the sewage discharge component 50 includes a force-bearing portion 53, which is located outside the sewage discharge channel 51 in the radial direction along the sewage discharge channel 51. Specifically, in some embodiments, the force-bearing portion 53 is provided with a mating surface 531. When the mating surface 531 is not subjected to external force, the sewage discharge component 50 is in a non-discharged state; when the mating surface 531 is subjected to external force, the sewage discharge component 50 rotates relative to the sewage tank 30 in a first direction to switch from a non-discharged state to a discharged state.

[0225] Specifically, the drain component 50 includes a main body and a force-receiving part 53. The force-receiving part 53 is used to cooperate with other components to receive the force applied to the drain component 50 by those components. When the force applied to the mating surface 531 of the force-receiving part 53 by other components changes, the force-receiving part 53 can drive the main body to rotate in a first direction and a second direction. The force-receiving part 53 can be located at any position on the side wall of the main body. The force-receiving part 53 and the main body can be an integral structure or separate structures. When the force-receiving part 53 and the main body are an integral structure, they can be integrally formed. When the force-receiving part 53 and the main body are separate structures, they can be detachably or non-detachably connected.

[0226] When the cleaning module 200 needs to drain, the mating surface 531 is subjected to force, causing the force-bearing part 53 to rotate in the first direction, and the draining component 50 to rotate relative to the sewage tank 30 in the first direction. In the height direction H of the sewage tank 30, the height of the drain outlet 511 gradually decreases, thus switching the draining component 50 from a non-draining state to a draining state. When the cleaning module 200 has completed draining or is cleaning the surface to be cleaned, the external force on the mating surface 531 disappears, causing the force-bearing part 53 to rotate in the second direction, and the draining component 50 to rotate relative to the sewage tank 30 in the second direction. In the height direction H of the sewage tank 30, the height of the drain outlet 511 gradually increases, thus switching the draining component 50 from a draining state to a non-draining state.

[0227] Please see Figure 10In some embodiments, the external force on the mating surface 531 is a contact-type tensile or compressive force. When the cleaning module 200 needs to discharge wastewater, the mating surface 531 is used to contact other components. In the height direction H of the wastewater tank 30, if the component applying force to the mating surface 531 is lower than the discharge component 50, other components can apply tensile force to the mating surface 531 to cause the discharge component 50 to rotate in a first direction, thereby switching the discharge component 50 from a non-discharge state to a discharge state, and allowing waste in the wastewater tank 30 to be discharged from the discharge channel 51. In the height direction H of the wastewater tank 30, if the component applying force to the mating surface 531 is higher than the discharge component 50, other components can apply compressive force to the mating surface 531 to cause the discharge component 50 to rotate in a first direction, thereby switching the discharge component 50 from a non-discharge state to a discharge state, and allowing waste in the wastewater tank 30 to be discharged from the discharge channel 51.

[0228] When the external force on the mating surface 531 is a contact-type tensile or compressive force, the external force on the mating surface 531 is relatively large, and the drain component 50 can rotate in the first direction. Moreover, the force on the drain component 50 is relatively stable at this time, which can avoid the problem that the drain component 50 cannot rotate in the first direction when the cleaning module 200 needs to drain (for example, when the magnetism weakens and the magnetic attraction disappears).

[0229] Please see Figure 10In other embodiments, the external force on the mating surface 531 is a non-contact repulsive or attractive force. Preferably, the external force on the mating surface 531 can be a magnetic repulsive or attractive force. In one example, the mating surface 531 may be provided with a first magnetic attractor, and the water system 100 may also include a second magnetic attractor, with the first and second magnetic attractors repelling each other. When the cleaning module 200 needs to discharge wastewater, the second magnetic attractor may be higher than the discharge component 50 in the height direction H of the wastewater tank 30. The first magnetic attractor and the second magnetic attractor repel each other, and the discharge component 50 is subjected to the repulsive force of the second magnetic attractor, so that the discharge component 50 can rotate in the first direction, and the discharge component 50 can switch from a non-discharged state to a discharged state, and the waste in the wastewater tank 30 can be discharged from the discharge channel 51. When all the wastewater in the wastewater tank 30 has been discharged, the discharge component 50 needs to switch from the discharged state to a non-discharged state. Exemplarily, both the first and second magnetic attractors can be electromagnets. When the discharge component 50 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 50 can then rotate in the first direction, switching from a non-discharge state to a discharge state. When all waste in the wastewater tank 30 has been discharged, the first and / or second magnetic components are de-energized, the repulsive force disappears, and the discharge component 50 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 50 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 50 to rotate in the first direction, switching from a non-discharge state to a discharge state. When all the waste in the sewage tank 30 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 50 can rotate in the second direction, and the sewage discharge device 50 can switch from the sewage discharge state to the non-sewage discharge state.

[0230] In another example, the mating surface 531 may be provided with a first magnetic attractor, and the water system 100 may also include a second magnetic attractor, with the first and second magnetic attractors attracting each other. When the cleaning module 200 needs to discharge wastewater, the second magnetic attractor may be lower than the discharge component 50 in the height direction H of the wastewater tank 30. The first magnetic attractor and the second magnetic attractor attract each other, and the discharge component 50 is attracted by the second magnetic attractor, so the discharge component 50 can rotate in the first direction, and the discharge component 50 can switch from a non-discharge state to a discharge state, and the wastewater in the wastewater tank 30 can be discharged from the discharge channel 51.

[0231] In another example, the mating surface 531 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 50 to rotate in 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 50 to rotate in a second direction, and the discharge device 50 can switch from a discharge state to a non-discharge state.

[0232] When the external force on the mating surface 531 is a non-contact repulsive or attractive force, the mating surface 531 does not need to contact other components, thus the wear on the mating surface 531 is small, and the service life of the drain component 50 is long. Moreover, when the mating surface 531 is subjected to repulsive or attractive forces, the drain component 50 can quickly rotate along the first direction, and the drain component 50 can switch from a non-drainage state to a drainage state at a relatively fast speed.

[0233] Please see Figures 10 to 12 In some embodiments, the water system 100 further includes a reset member 70. One end of the reset member 70 is connected to the sewage channel 11 or the main body 201, and the other end is connected to the discharge member 50. When the external force on the discharge member 50 disappears, the reset member 70 drives the discharge member 50 to rotate in a second direction, thereby switching from a discharge state to a non-discharge state. Since, in its natural state, the height of the discharge port 511 is higher than the height of the inlet port 513, or the height of the discharge port 511 is higher than the highest liquid level in the sewage tank 30, when the discharge member 30 is in its natural state, the waste in the sewage tank 30 cannot flow out from the discharge port 511, and the discharge member 30 is in a non-discharge state. When the external force on the discharge member 30 disappears, the reset member 70 drives the discharge member 30 back to its natural state, so that the discharge member 30 can quickly switch to a non-discharge state.

[0234] When the cleaning module 200 needs to discharge wastewater, the discharge component 50 is subjected to external force, allowing it to rotate in a first direction, thus switching from a non-discharge state to a discharge state. During the discharge process of the cleaning module 200, the discharge component 50 is continuously subjected to external force to maintain its discharge state. Once all wastewater in the wastewater tank 30 has been discharged outside the wastewater link 10, the external force on the discharge component 50 disappears, and the reset component 70 can restore the discharge component 50 to its non-discharge state.

[0235] In one embodiment, the reset member 70 may be a torsion spring, which is in its natural state when the drain member 50 is in an undrained state. When the drain member 50 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 50 to rotate in a second direction. Thus, when the external force on the drain member 50 disappears, the torsion spring can drive the drain member 50 to rotate in the second direction, switching the drain member 50 from a draining state to an undrained state, and the torsion spring returns to its natural state.

[0236] When the water system 100 includes a reset member 70, the reset member 70 can automatically return the drain member 50 to the non-drained state when it is not subjected to external force. During the rotation of the drain member 50 in the second direction, the water system 100 does not need to set up any other components to apply external force to the drain member 50. The way the drain member 50 rotates in the second direction is relatively simple, and the drain member 50 switches from the drained state to the non-drained state quickly.

[0237] Please see Figure 1 and Figure 10 In some embodiments, the water system 100 further includes a drive unit 80, which is connected to the drain unit 50 and is used to drive the drain unit 50 to rotate to switch between a non-drained state and a drained state.

[0238] Specifically, when the cleaning module 200 is cleaning the surface to be cleaned, the drive unit 80 drives the draining unit 50 to rotate in the second direction, so that the draining unit 50 switches from a draining state to a non-draining state. When the cleaning module 200 needs to drain, the drive unit 80 drives the draining unit 50 to rotate in the first direction, so that the draining unit 50 switches from a non-draining state to a draining state.

[0239] Please see Figure 1 and Figure 10 In some embodiments, the cleaning module 200 includes a position detection unit and a processing unit. The position detection unit is used to detect the position of the cleaning module 200 relative to the body 300 of the cleaning device 1000. The processing unit is used to determine whether the position of the cleaning module 200 relative to the body 300 meets a predetermined condition based on the detection information from the position detection unit, and to control the operation of the drive unit 80 based on the determination result.

[0240] Specifically, in some embodiments, the cleaning module 200 can move relative to the body 300 of the cleaning device 1000 to a first relative position and a second relative position. When the cleaning module 200 is in the second relative position, its maximum profile width is greater than that when it is in the first relative position. When the cleaning module 200 moves from the first relative position to the second relative position, the processing unit controls the drive member 80 to drive the drain member 50 to rotate relative to the sewage tank 30 in a first direction to switch from a non-drained state to a drained state. When the cleaning module 200 moves from the second relative position to the first relative position, the processing unit controls the drive member 80 to drive the drain member 50 to rotate relative to the sewage tank 30 in a second direction to switch from a drained state to a non-drained state. The first direction is opposite to the second direction.

[0241] In the first relative position, the cleaning module 200 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 200. In the second relative position, one end of the cleaning module 200 can protrude from one side of the body 300 of the cleaning device 1000. The position of the cleaning module 200 relative to the body 300 satisfies the predetermined condition when the cleaning module 200 is in either the first relative position or the second relative position relative to the body 300 of the cleaning device 1000.

[0242] When the cleaning module 200 needs to be discharged, it 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 200 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 200 has reached the second relative position, it controls the drive unit 80 to drive the discharge unit 50 to rotate relative to the wastewater tank 30 in a first direction, thereby switching the discharge unit 50 from a non-discharge state to a discharge state.

[0243] When the cleaning module 200 is cleaning the surface to be cleaned, the cleaning module 200 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 200 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 200 has reached the first relative position, it controls the drive unit 80 to drive the drain component 50 to rotate relative to the wastewater tank 30 in a second direction, thereby switching from a drain state to a non-drain state.

[0244] The position detection unit is communicatively connected to the processing unit, which in turn is communicatively connected to the drive unit 80. By detecting the relative position of the cleaning module 200 to the body 300 of the cleaning equipment 1000 through the position detection unit, the processing unit can control the drive unit 80 to switch the drain component 50 between a non-draining state and a draining state. When draining is required, the drain component 50 automatically switches to the draining state by rotating. The entire process requires no manual intervention, the switching efficiency of the drain component 50 is high, and the user experience is good.

[0245] When the drain component 50 is made of rigid material, it needs to rotate relative to the sewage tank 30 (sewage channel 11) to switch between a non-drained state and a drained state. After a certain period of use, the connection between the drain component 50 and the side wall of the sewage channel 11 may become worn. With wear at the connection, a gap will exist between the sewage channel 11 and the drain component 50, potentially affecting the seal. As waste flows from the sewage channel 11 to the drain channel 51, some of it may leak out through this gap and flow onto the surface to be cleaned, causing secondary contamination.

[0246] Please see Figure 11 and Figure 12 In some embodiments, the sewage discharge component 50 includes a first sub-part 55 and a second sub-part 57. The first sub-part 55 is sleeved on the second sub-part 57. The force-bearing part 53 of the sewage discharge component 50 is provided on the side wall of the first sub-part 55. The sewage discharge channel 51 is opened in the second sub-part 57. The first sub-part 55 is a rigid pipe, and the second sub-part 57 is a flexible pipe. The second sub-part 57 is sealed and connected to the sewage channel 11.

[0247] Specifically, the first sub-part 55 is used to rotate relative to the sewage tank 30 under external force. The first sub-part 55 can drive the second sub-part 57 to rotate together, so that the sewage discharge component 50 can switch between a non-discharged state and a discharged state. The second sub-part 57 is used to connect to the sewage channel 11, so that the sewage in the sewage channel 11 can flow out from the sewage discharge channel 51 of the second sub-part 57 to the outside of the sewage link 10. Since the second sub-part 57 is a flexible hose, the connection between the second sub-part 57 and the sewage channel 11 is not easily worn during the rotation process, which can ensure good sealing at the connection between the second sub-part 57 and the sewage channel 11, thereby preventing the problem of sewage flowing out from the gap between the sewage channel 11 and the second sub-part 57.

[0248] When the first sub-section 55 is a rigid tube, it is not easily deformed under external force, allowing it to rotate and drive the second sub-section 57 to rotate. The first sub-section 55 and the second sub-section 57 rotate together, allowing the drain component 50 to switch between a non-drained state and a drained state. The material of the first sub-section 55 can be, but is not limited to, metal or plastic. When the first sub-section 55 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-section 55 is made of plastic, it is lighter and has lower cost. When the second sub-part 57 is a flexible hose, the sealing effect between the second sub-part 57 and the sewage channel 11 is better. Furthermore, during rotation, the flexibility of the second sub-part 57 allows it to buffer the tensile force at the connection point with the sewage channel 11 when rotated by the first sub-part 55. This reduces wear between the second sub-part 57 and the sewage channel 11, minimizing the gap between them and reducing the likelihood of waste leaking out through the gap between the side wall of the sewage channel 11 and the second sub-part 57. The material of the second sub-part 57 can be, but is not limited to, rubber, silicone, or polyethylene.

[0249] Please see Figures 11 to 13 Furthermore, in some embodiments, the sidewall of the first sub-part 55 is provided with a rotating shaft 551, which is connected to the main body 201 and can rotate relative to the main body 201. Specifically, as the first sub-part 55 rotates relative to the main body 201 along a first direction and a second direction, the rotating shaft 551 also rotates relative to the main body 201. The connection between the rotating shaft 551 and the main body 201 provides a certain supporting force to the first sub-part 55, thereby making the first sub-part 55 more stable during rotation along the first and second directions.

[0250] Please see Figure 11 and Figure 13 In some embodiments, a first gap 58 is provided between the first sub-part 55 and the second sub-part 57. In this case, during the rotation of the second sub-part 57 by the first sub-part 55, the friction between the first sub-part 55 and the second sub-part 57 is reduced, thereby preventing mutual wear between them. The first sub-part 55 and the second sub-part 57 are less prone to damage and have a longer service life.

[0251] Please see Figure 11 and Figure 13In some embodiments, the first sub-part 55 includes a first end 553 and a second end 555 opposite to each other, the first end 553 of the first sub-part 55 being closer to the sewage channel 11 than the second end 555 of the first sub-part 55; the second sub-part 57 includes a first end 571 and a second end 573 opposite to each other, the first end 571 of the second sub-part 57 being closer to the sewage channel 11 than the second end 573 of the second sub-part 57; the first end 571 of the second sub-part 57 is closer to the sewage channel 11 than the first end 553 of the first sub-part 55, and the first end 571 of the second sub-part 57 is sealed to the sewage channel 11.

[0252] The inlet 513 is located at the first end 571 of the second sub-part 57, and the outlet 511 is located at the second end 573 of the second sub-part 57. The first end 553 of the first sub-part 55 is connected to the side wall of the sewage channel 11, and the second end 555 of the first sub-part 55 is close to the outlet 511. When the first end 571 of the second sub-part 57 is closer to the sewage channel 11 than the first end 553 of the first sub-part 55, that is, the first end 571 of the second sub-part 57 protrudes relative to the first end 553 of the first sub-part 55. Since the first end 571 of the second sub-part 57 is sealed to the sewage channel 11, sewage in the sewage channel 11 is prevented from flowing into the first gap 58, and sewage is also prevented from flowing out from the side wall of the sewage channel 11 and the second end 573 of the second sub-part 57. All sewage in the sewage channel 11 enters the outlet 51 from the inlet 513 of the first end 571 of the second sub-part 57 and is discharged from the outlet 511.

[0253] Please see Figure 11 and Figure 12 In some embodiments, the second end 573 of the second sub-part 57 is flush with the second end 555 of the first sub-part 55. In this case, when waste flows out of the drain outlet 51 from the drain channel 51, the probability of waste flowing into the first gap 58 from the second end 573 of the second sub-part 57 is reduced. In other embodiments, the second end 573 of the second sub-part 57 extends beyond the second end 555 of the first sub-part 55. In this case, when waste flows out of the drain outlet 511 from the drain channel 51, the probability of waste flowing into the first gap 58 from the second end 573 of the second sub-part 57 is further reduced.

[0254] Please see Figure 13 and Figure 14Furthermore, in some embodiments, the second end 573 of the second sub-part 57 extends beyond the second end 555 of the first sub-part 55 and covers the second end 555 of the first sub-part 55. The gap between the second end 573 of the second sub-part 57 and the second end 555 of the first sub-part 55 can be covered by the bend 575 of the second sub-part 57, so that all the dirt flowing out from the second end 573 of the second sub-part 57 can be discharged outside the sewage link 10, and the dirt will not flow into the first gap 58 from the second end 573 of the second sub-part 57.

[0255] Please see Figure 13 and Figure 14 Furthermore, in some embodiments, a second gap 59 is provided between the turning portion 575 of the second end 573 of the second sub-part 57 and the second end 555 of the first sub-part 55.

[0256] During the rotation of the second sub-part 57 driven by the first sub-part 55, the connection between the sewage channel 11 and the first end 571 of the second sub-part 57 exerts a certain pulling force on the second sub-part 57. When there is no gap between the turning portion 575 of the second end 573 of the second sub-part 57 and the second end 555 of the first sub-part 55, the second sub-part 57 is easily damaged when the connection between the sewage channel 11 and the first end 571 of the second sub-part 57 pulls on it. In this embodiment, a second gap 59 is provided between the turning portion 575 and the second end 555 of the first sub-part 55. When the second sub-part 57 is pulled at the connection between the sewage channel 11 and the first end 571 of the second sub-part 57, the second gap 59 provides a certain deformation space for the second sub-part 57, thus making the second sub-part 57 less prone to damage and improving its service life.

[0257] Please see Figure 1 , Figure 10 , Figure 15 and Figure 16 In some embodiments, the drain component 50 can be deformed under external force on the outside of the drain channel 51 to switch between a non-drainage state and a drainage state. When the drain component 50 is in the drainage state, the drain channel 51 is in the conducting state, and when the drain component 50 is in the non-drainage state, the drain channel 51 is in the closed state.

[0258] Specifically, when the drain component 50 is deformable under external force, the drain component 50 can be a flexible hose, and the material of the drain component 50 can be, but is not limited to, rubber, silicone, or polyethylene. The drain channel 51 being in a conductive state means that waste flowing into the drain channel 51 from the sewage channel 11 can flow out from the drain outlet 511 to the outside of the sewage link 10. At this time, the minimum cross-sectional area of ​​the drain channel 51 only needs to be greater than 0. In one example, when the drain channel 51 is in a conductive state, the drain component 50 is not subjected to external force and is in a natural state. At this time, the cross-sectional area of ​​the drain channel 51 is equal at all locations, and the cross-sectional area of ​​the drain channel 51 is relatively large, allowing waste flowing into the drain channel 51 from the sewage channel 11 to be quickly discharged to the outside of the sewage link 10. In another example, when the drain channel 51 is in a conductive state, the drain component 50 is subject to external force, and the drain component 50 is in a partially deformed state; the minimum cross-sectional area of ​​the drain channel 51 is greater than 0. The sewage discharge channel 51 being in the closed state means that the sewage flowing into the sewage discharge channel 51 from the sewage channel 11 cannot flow out of the sewage outlet 511 to the outside of the sewage link 10. At this time, the minimum cross-sectional area of ​​the sewage discharge channel 51 is 0. When the sewage discharge channel 51 is in the closed state, the side wall of the sewage discharge component 50 is subjected to external force, and the sewage discharge component 50 is in a fully deformed state.

[0259] Please see Figure 1 , Figure 10 , Figure 15 and Figure 16 In some embodiments, when the drain component 50 is in the draining state, the height of the drain outlet 511 relative to the sewage tank 30 is the same as the height of the drain outlet 511 relative to the sewage tank 30 when the drain component 50 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 511 relative to the sewage tank 30 remains unchanged. At this time, in the height direction H of the sewage tank 30, the height of the drain outlet 511 relative to the height of the inlet 513 remains unchanged; the drain outlet 511 is flush with the inlet 513 or lower than the inlet 513. The overall position of the drain component 50 relative to the sewage tank 30 remains unchanged.

[0260] When the cleaning module 200 is cleaning the surface to be cleaned, the drain component 50 is subjected to external force and deforms, thereby closing the drain channel 51 and preventing the dirt in the receiving cavity 31 from being discharged from the drain port 511 to the outside of the sewage link 10. When the cleaning module 200 needs to discharge, the drain component 50 may be unaffected by external force or subjected to a small external force, and the drain component 50 may be in a natural state or a state of slight deformation, thereby opening the drain channel 51 and allowing the dirt in the receiving cavity 31 to be discharged from the drain port 511 to the outside of the sewage link 10.

[0261] When the drain component 50 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 50, making the switch relatively simple. When the external force on the drain component 50 decreases or disappears, the waste in the sewage channel 11 can flow out of the drain channel 51 to the outside of the sewage link 10, and the waste in the receiving cavity 31 is discharged from the drain channel 51 at a relatively fast speed.

[0262] Please see Figure 15 and Figure 16 In some embodiments, the cleaning module 200 further includes a force-applying member 90, which is used to apply an external force to the drain member 50 to make the drain channel 51 either open or closed. Specifically, in some embodiments, when the force-applying member 90 applies an external force to the side wall of the drain member 50, the drain channel 51 is in a closed state; when the external force applied by the force-applying member 90 to the drain member 50 disappears, the drain channel 51 is in an open state.

[0263] Specifically, the force-applying member 90 can be disposed on the main body 201. The force-applying member 90 applies an external force to the sewage discharge member 50, thereby deforming the sewage discharge member 50. When the external force applied to the sewage discharge member 50 by the force-applying member 90 disappears, the sewage discharge member 50 can return to its natural state. When the sewage discharge channel 51 is closed, the force-applying member 90 is in contact with the sewage discharge member 50. When the sewage discharge channel 51 is open, the force-applying member 90 can be spaced apart from the sewage discharge member 50.

[0264] During the cleaning process of the cleaning module 200, the force-applying component 90 applies external force to the side wall of the drain component 50, causing the drain component 50 to deform. This closes the drain channel 51, and the drain component 50 is in an undrained state, preventing dirt from being discharged from the drain port 511 in the receiving cavity 31. This avoids the problem of dirt flowing onto the surface to be cleaned. When the cleaning module 200 needs to drain, the force-applying component 90 removes the external force on the drain component 50, leaving it in a natural state. This opens the drain channel 51, and the drain component 50 is in a drained state, allowing dirt to flow out from the drain port 511. At this time, the cross-sectional area of ​​the drain channel 51 is large, allowing dirt to flow out quickly.

[0265] Please see Figure 10 , Figure 15 and Figure 16 In some embodiments, the water system 100 further includes a drive unit connected to the force-applying member 90, which is used to drive the force-applying member 90 to apply or remove the applied force to the sewage discharge member 50.

[0266] When the cleaning module 200 is cleaning the surface to be cleaned, the drive unit drives the force-applying component 90 to apply external force to the side wall of the drain component 50, causing the drain component 50 to deform and the drain channel 51 to be closed. Dirt cannot be discharged from the drain port 511, thus preventing dirt from flowing onto the surface to be cleaned. When the cleaning module 200 needs to drain, the drive unit drives the force-applying component 90 to remove the external force on the drain component 50, so the drain component 50 is no longer subject to external force, returns to its natural state, the drain channel 51 is open, and dirt can flow out from the drain port 511.

[0267] The drive unit can communicate with the processing unit. The processing unit determines whether the position of the cleaning module 200 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 cleaning module 200 needs to be drained, the cleaning module 200 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 200 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 200 has reached the second relative position, the processing unit controls the drive unit to release the pressure applied to the drain component 50, so that the drain channel 51 is in a conductive state. When the cleaning module 200 is cleaning the surface to be cleaned, the cleaning module 200 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 200 is in a 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 200 has reached the first relative position, the processing unit controls the drive unit to apply external force to the drain component 50 to close the drain channel 51.

[0268] Please see Figure 17 Secondly, embodiments of this application provide a cleaning module 200, which includes the water system 100 described in the above embodiments.

[0269] Please see Figure 1 and Figure 2 In some embodiments, the cleaning module 200 includes a body 201, and the sewage link 10 and the power system 20 may both be located on the body 201.

[0270] The wastewater link 10 can be detachably or non-detachably connected to the main body 201. 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 link 10 is detachably connected to the main body 201, it can be easily removed from the main body 201 for repair in case of damage. When the wastewater link 10 is non-detachably connected to the main body 201, the wastewater link 10 and the main body 201 can be integrally molded, simplifying the processing steps of the cleaning module 200.

[0271] The power system 20 can be detachably or non-detachably connected to the body 201. 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, adhesive bonding, or interference fits. When the power system 20 is detachably connected to the body 201, it can be easily removed from the body 201 for repair in case of damage. When the power system 20 is non-detachably connected to the body 201, the power system 20 and the body 201 can be integrally molded, simplifying the processing steps of the cleaning module 200.

[0272] Please see Figures 5 to 7 In some embodiments, the cleaning module 200 also includes a clean water tank disposed on the main body 201, which is connected to the inlet 331 and is used to store cleaning liquid.

[0273] The cleaning liquid here refers to the same "liquid" as mentioned above, including clean water, cleaning solution, or a mixture containing cleaning solution. When the cleaning module 200 cleans the surface to be cleaned, the clean water tank provides the cleaning liquid to the mop 203 to keep it moist, resulting in better cleaning of the surface. When the wastewater tank 30 needs cleaning, the clean water tank provides the cleaning liquid to it. The clean water tank is connected to the inlet 331, and the cleaning liquid in the clean water tank enters the channel 33 from the inlet 331 and is sprayed onto the inner wall of the wastewater tank 30 from the outlet 35 to clean it. When liquid and dirt in the wastewater tank 30 flow out from the connecting pipe 13, the wastewater channel 11, and the drain outlet 511, the cleaning liquid also cleans the connecting pipe 13, the wastewater channel 11, and the drain 50.

[0274] When the clean water tank of the cleaning module 200 supplies cleaning liquid to the wastewater tank 30, the distance between the clean water tank and the wastewater tank 30 is relatively short, resulting in a shorter time for the cleaning liquid to flow from the clean water tank into the wastewater tank 30, thus achieving higher cleaning efficiency for the wastewater tank 30. Furthermore, even when the cleaning equipment 1000 moves, the relative distance between the clean water tank and the wastewater tank 30 remains constant, allowing the clean water tank to supply cleaning liquid to the wastewater tank 30 at any time, making cleaning of the wastewater tank 30 more convenient.

[0275] In the cleaning module 200 of this application embodiment, the power system 20 switches between a first state and a second state. Dirt in the sewage channel 11 can enter and be stored in the receiving cavity 31. Liquid and dirt in the receiving cavity 31 can also be discharged outside the water system 100 through the sewage channel 11. When the external liquid cleans the sewage tank 30, liquid in the receiving cavity 31 can flow through the sewage channel 11, cleaning the sewage channel 11. The liquid can also carry dirt from the sewage link 10 and discharge it outside the water system 100. Compared to the current water system 100, the sewage link 10 in the water system 100 of this application has higher cleaning efficiency, does not accumulate more dirt on the sewage link 10, and does not require manual cleaning, resulting in a better user experience.

[0276] Please see Figure 17 Thirdly, embodiments of this application provide a cleaning device 1000, which includes a body 300 and a cleaning module 200 as described above, with the cleaning module 200 disposed on the body 300.

[0277] In some embodiments, the cleaning device 1000 also includes a clean water tank disposed on the main body 201 and / or the body 300, the clean water tank being connected to the inlet 331 of the wastewater tank 30 and used to store cleaning liquid.

[0278] The cleaning liquid referred to here is the same as the "liquid" mentioned above, including clean water, cleaning solution, or a mixture of clean water and cleaning solution. In one embodiment, a clean water tank is disposed on the body 201 of the cleaning module 200. The clean water tank here has the same structure as the clean water tank in the second aspect, and will not be described in detail here.

[0279] Please combine Figure 1In another embodiment, a clean water tank is provided on the body 300. The clean water tank on the body 300 is used to provide cleaning liquid to the mopping component 203, and also to provide cleaning liquid to the wastewater tank 30. When the wastewater tank 30 needs cleaning, the clean water tank on the body 300 provides cleaning liquid to the wastewater tank 30. The clean water tank is connected to the inlet 331 via a pipe. The cleaning liquid in the clean water tank enters the channel 33 from the inlet 331 and is sprayed from the outlet 35 onto the inner wall of the wastewater tank 30 to clean it. When liquid and dirt in the wastewater tank 30 flow out from the connecting pipe 13, the wastewater channel 11, and the drain outlet 511, the cleaning liquid is also used to clean the connecting pipe 13, the wastewater channel 11, and the drain component 50.

[0280] When the clean water tank mounted on the machine body 300 supplies cleaning liquid to the wastewater tank 30, the close proximity of the clean water tank and the wastewater tank 30 results in a shorter time for the cleaning liquid to flow from the clean water tank into the wastewater tank 30, leading to higher cleaning efficiency for the wastewater tank 30. Furthermore, even when the cleaning equipment 1000 moves, the relative distance between the clean water tank and the wastewater tank 30 remains constant, allowing the clean water tank to supply cleaning liquid to the wastewater tank 30 at any time, making cleaning the wastewater tank 30 more convenient.

[0281] Please see Figure 17 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 200 to move relative to the body 300 along the width direction of the body 300, so that the cleaning module 200 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 200 to move along the width direction of the body 300, so that the cleaning module 200 is in the first relative position relative to the body 300. When the cleaning module 200 needs to be drained, it is driven to move along the width direction of the body 300, so that the cleaning module 200 is in the second relative position relative to the body 300. In some embodiments, the cleaning device 1000 also 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 200 and the body 300. The processor is used to determine whether the relative position of the cleaning module 200 and the body 300 meets the predetermined conditions based on the detection information of the position sensor, and controls the operation of the driver 500 based on the determination result.

[0282] Specifically, in some embodiments, when the processor receives a sewage discharge start command and the detection information indicates that the cleaning module 200 is in a first relative position, the processor controls the driver 500 to drive the cleaning module 200 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 200 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 200 is in the second relative position, the processor controls the driver 500 to drive the cleaning module 200 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 200 is in the first relative position, the processor controls the driver 500 to stop driving.

[0283] 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 200 needs to be drained, the processor can control the driver 500 to move the cleaning module 200 to a second relative position.

[0284] When the cleaning equipment 1000 needs to discharge wastewater, the position sensor detects the position of the cleaning module 200 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 200 is in the first relative position, the processor controls the driver 500 to move the cleaning module 200 forward relative to the body 300 along the width direction of the body 300, causing the cleaning module 200 to protrude from one side of the body 300. When the position sensor detects that the cleaning module 200 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 200. When the cleaning module 200 is in the second relative position, the discharge component 50 is in a discharge state under the action of external force, allowing the wastewater in the wastewater tank 30 to be discharged outside the cleaning equipment 1000.

[0285] When the cleaning equipment 1000 has completed its wastewater discharge, the position sensor detects the position of the cleaning module 200 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 200 is in the second relative position, the processor controls the driver 500 to move the cleaning module 200 in the opposite direction of the width of the body 300 relative to it. When the position sensor detects that the cleaning module 200 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 200. When the cleaning module 200 is in the first relative position, the wastewater discharge component 50 is in an undischarged state, thus preventing waste from being discharged from the wastewater tank 30.

[0286] In the cleaning device 1000 of this application embodiment, the power system 20 switches between a first state and a second state. Dirt in the sewage channel 11 can enter and be stored in the receiving cavity 31. Liquid and dirt in the receiving cavity 31 can also be discharged outside the water system 100 through the sewage channel 11. When the external liquid cleaning sewage tank 30 is used, liquid in the receiving cavity 31 can flow through the sewage channel 11, cleaning the sewage channel 11. The liquid can also carry dirt from the sewage link 10 and discharge it outside the water system 100. Compared to the current water system 100, the sewage link 10 in the water system 100 of this application has higher cleaning efficiency, does not accumulate more dirt on the sewage link 10, and does not require manual cleaning, resulting in a better user experience.

[0287] Please see Figure 18 and Figure 19 Fourthly, the embodiments of this application also provide a base station 3000, which includes a main body 3001 and a force-applying member 3003. The force-applying member 3003 is installed on the main body 3001 and is used to cooperate with the sewage discharge member 50. When the external force applied by the force-applying member 3003 to the outside of the sewage discharge member 50 changes, the sewage discharge member 50 can switch between a non-discharged state and a discharged state.

[0288] 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 position where the cleaning equipment 1000 can enter, facilitating cleaning of its mopping component 203 and charging. Furthermore, the base station 3000 may also have at least one of the following functions: replenishing water, draining water, and collecting dust from the cleaning equipment 1000. When the mopping component 203 of the cleaning equipment 1000 is dirty and / or has insufficient power, the cleaning equipment 1000 returns to the base station 3000 to clean and / or recharge its components. After cleaning and / or fully charging the mopping component 203, the cleaning equipment 1000 can leave the base station 3000 and continue cleaning the surface to be cleaned.

[0289] In one embodiment, when the cleaning equipment 1000 enters the base station 3000 and needs to be drained, the force-applying member 3003 applies an external force to the side wall of the draining member 50, thereby switching the draining member 50 from a non-draining state to a draining state. Dirt in the receiving cavity 31 can flow into the base station 3000 from the drain port 511. In another embodiment, when the cleaning equipment 1000 enters the base station 3000 and needs to be drained, the force-applying member 3003 removes the external force applied to the side wall of the draining member 50, thereby switching the draining member 50 from a non-draining state to a draining state. Dirt in the receiving cavity 31 can flow into the base station 3000 from the drain port 511.

[0290] After the cleaning device enters the base station 3000, it will come into contact with the tray of the main body 3001. Preferably, the force-applying component 3003 can be installed on the tray, and the force-applying component 3003 can be detachably or non-detachably connected to the tray. When the force-applying component 3003 is installed on the tray, it is convenient for the force-applying component 3003 to cooperate with the sewage discharge component 50.

[0291] Please see Figure 1 and Figure 10 In some embodiments, when the drain component 50 is in the draining state, the height of the drain outlet 511 of the drain component 50 is lower than the height of the drain outlet 511 when the drain component 50 is in the non-draining state.

[0292] The drain component 50 can rotate relative to the wastewater tank 30. During the rotation of the drain component 50, the height of the drain outlet 511 in the height direction H of the wastewater tank 30 becomes variable. When the cleaning module 200 is cleaning the surface to be cleaned, under the action of external force, the drain component 50 can rotate relative to the wastewater tank 30 in a first direction, so that the height of the drain outlet 511 is higher, making it difficult for dirt to flow out of the drain outlet 511. At this time, the drain component 50 is in a non-draining state. When the cleaning module 200 needs to drain, under the action of external force, the drain component 50 can rotate relative to the wastewater tank 30 in a second direction, so that the height of the drain outlet 511 is lower, and the dirt in the drain channel 51 can flow out of the drain outlet 511. At this time, the drain component 50 is in a draining state. The drain component 50 switches between the draining state and the non-draining state by rotating, and the flow of dirt from the drain channel 51 is relatively smooth, and there is no problem of blockage inside the drain channel 51.

[0293] Please see Figures 20 to 22 In some embodiments, the force-applying member 3003 includes a guide portion 3005 and a mounting portion 3007. The guide portion 3005 is provided with a guide surface 3006, which mates with the mating surface 531. The mounting portion 3007 is connected to the main body 3001.

[0294] Specifically, the mounting part 3007 is used to connect the force-applying member 3003 to the main body 3001, so that the force-applying member 3003 is securely installed on the main body 3001. In one embodiment, after the cleaning equipment 1000 enters the base station 3000, the guide surface 3006 mates with the mating surface 531. Figure 20 As shown). The guide part 3005 transmits external force to the drain member 50 through the guide surface 3006, so that the drain member 50 can rotate in the first direction (as shown). Figure 21 (As shown). When the sewage discharge component 50 switches from a non-sewage discharge state to a sewage discharge state, the sewage in the receiving cavity 31 flows into the base station 3000 from the sewage discharge port 511. Figure 22 (As shown). When the cleaning module 200 leaves the base station 3000, the force-applying component 3003 is spaced apart from the sewage discharge component 50, that is, the guide surface 3006 is spaced apart from the mating surface 531. When the external force on the sewage discharge component 50 disappears, the reset component 70 can drive the sewage discharge component 50 to rotate in the second direction, and the sewage discharge component 50 switches from the sewage discharge state to the non-sewage discharge state.

[0295] In another embodiment, after the cleaning equipment 1000 enters the base station 3000, when the cleaning module 200 moves to a second relative position relative to the body 300, the force-applying component 3003 cooperates with the sewage discharge component 50, that is, the guide surface 3006 cooperates with the mating surface 531. Figure 20 As shown). The guide part 3005 transmits external force to the drain member 50 through the guide surface 3006, so that the drain member 50 can rotate in the first direction (as shown). Figure 21(As shown). When the sewage discharge component 50 switches from a non-sewage discharge state to a sewage discharge state, the sewage in the receiving cavity 31 flows into the base station 3000 from the sewage discharge port 511. Figure 22 (As shown). When the cleaning module 200 moves to the first relative position relative to the body 300, the force-applying component 3003 is spaced apart from the drain component 50, that is, the guide surface 3006 is spaced apart from the mating surface 531. When the external force on the drain component 50 disappears, the reset component 70 can drive the drain component 50 to rotate in the second direction, and the drain component 50 switches from the drain state to the non-drain state.

[0296] In another embodiment, after the cleaning equipment 1000 enters the base station 3000, the force-applying component 3003 can move relative to the main body 3001 to the position corresponding to the sewage discharge component 50, so that the force-applying component 3003 can cooperate with the sewage discharge component 50, that is, the guide surface 3006 cooperates with the mating surface 531. Figure 20 As shown). The guide part 3005 transmits external force to the drain member 50 through the guide surface 3006, so that the drain member 50 can rotate in the first direction (as shown). Figure 21 (As shown). When the sewage discharge component 50 switches from a non-sewage discharge state to a sewage discharge state, the sewage in the receiving cavity 31 flows into the base station 3000 from the sewage discharge port 511. Figure 22 (As shown). When the cleaning module 200 moves to the first relative position relative to the body 300, the force-applying member 3003 and the draining member 50 are spaced apart, that is, the guide surface 3006 and the mating surface 531 are spaced apart. When the external force on the draining member 50 disappears, the reset member 70 can drive the draining member 50 to rotate in the second direction, and the draining member 50 switches from the draining state to the non-draining state. In the embodiment of this application, after the cleaning equipment 1000 enters the base station 3000, when the cleaning module 200 moves to the second relative position relative to the body 300, the force-applying member 3003 and the draining member 50 cooperate.

[0297] Please see Figures 20 to 22 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.

[0298] In the height direction H of the sewage tank 30, after the cleaning equipment 1000 enters the base station 3000, the force-applying component 3003 is higher than the sewage discharge component 50. The guide surface 3006 is located on the bottom surface of the guide part 3005. When the sewage discharge component 50 is in the sewage discharge state, the mating surface 531 is located on the top surface of the sewage discharge component 50. 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 200 moving relative to the body 300 to the second relative position, the guide surface 3006 and the mating surface 531 begin to mate ( Figure 20As shown). At this time, the angle between the mating surface 531 and the bottom-to-top direction of the sewage tank 30 can be in the range of [0°, 90°]. During the mating process between the guide surface 3006 and the mating surface 531, the angle between the mating surface 531 and the bottom-to-top direction of the sewage tank 30 gradually increases (as shown). Figure 21 As shown). After the cleaning module 200 moves to the second relative position relative to the body 300, the mating surface 531 mates with the lowest point of the guide surface 3006. At this time, the angle between the mating surface 531 and the height direction H of the sewage tank 30 can be greater than or equal to 90°. Figure 22 (As shown). During the engagement of the guide surface 3006 and the mating surface 531, the drain outlet 511 begins to rotate along the first direction. The height of the drain outlet 511 gradually decreases along the height direction H of the sewage tank 30. When the mating surface 531 engages with the guide surface 3006 at its lowest point, the angle between the central axis of the drain outlet 511 extending away from the drain inlet 513 of the drain component 50 and the height direction from the bottom to the top of the sewage tank 30 is greater than or equal to 90°. At this time, the drain component 50 switches to the draining state, and the waste in the receiving cavity 31 can flow into the base station 3000 from the drain outlet 511.

[0299] Please see Figures 20 to 22 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 200 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 200 enters the main body 3001, the guide surface 3006 guides the mating surface 531, thereby further accelerating the rotation of the discharge component 50 along the first direction, allowing the contaminants in the receiving cavity 31 to be quickly discharged into the base station 3000.

[0300] Please see Figure 10 , Figures 23 to 24 In some embodiments, the cleaning module 200 is further provided with a clamping member 91; the force-applying member 3003 is used to apply external force to the drain member 50 through the clamping member 91, so that the drain channel 51 is in a conducting state or a closed state. Specifically, in some embodiments, when the force-applying member 3003 applies external force to the side wall of the drain member 50 through the clamping member 91, the drain channel 51 is in a closed state; when the external force applied by the force-applying member 3003 to the drain member 50 through the clamping member 91 disappears, the drain channel 51 is in a conducting state.

[0301] The sidewall of the drain component 50 can deform under external force. When the drain channel 51 is open, the drain component 50 is in a draining state. When the drain channel 51 is closed, the drain component 50 is in a non-draining state. When the drain component 50 is in a draining state, the height of the drain outlet 511 relative to the sewage tank 30 is the same as when the drain component 50 is in a non-draining state.

[0302] The clamping member 91 cooperates with the force-applying member 3003. The force-applying member 3003 applies an external force to the clamping member 91, thereby allowing the clamping member 91 to apply an external force to the drain member 50, keeping the drain channel 51 closed. When the cleaning module 200 is cleaning the surface to be cleaned, the clamping member 91 maintains the external force applied to the drain member 50, preventing dirt in the receiving cavity 31 from flowing out of the drain port 511 to the surface to be cleaned. After the device module enters the base station 3000, the force-applying member 3003 can release the external force applied by the clamping member 91 to the drain member 50, allowing dirt to flow into the base station 3000 from the drain port 511. After the cleaning module 200 has finished draining, the force-applying member 3003 can apply an external force to the clamping member 91, thereby allowing the clamping member 91 to apply an external force to the drain member 50, keeping the drain channel 51 closed.

[0303] Please see Figure 23 and Figure 24 In one embodiment, when the cleaning device 1000 enters the base station 3000, the force-applying member 3003 engages with the clamping member 91. The force-applying member 3003 can release the external force exerted by the clamping member 91 on the drain member 50, leaving the drain member 50 in a natural state. This allows the drain channel 51 to be open, and the drain member 50 to be in a draining state, enabling waste to flow out from the drain port 511. At this time, the drain channel 51 has a large cross-sectional area, allowing waste to flow out quickly. When the cleaning device 1000 has completed draining, the force-applying member 3003 can apply pressure to the side wall of the drain member 50 through the clamping member 91. This causes the drain member 50 to deform, closing the drain channel 51 and leaving the drain member 50 in a draining state. Waste in the receiving cavity 31 cannot be discharged from the drain port 511.

[0304] In another embodiment, after the cleaning device 1000 enters the base station 3000, when the cleaning module 200 moves to a second relative position relative to the body 300, the force-applying member 3003 cooperates with the clamping member 91. The force-applying member 3003 can release the external force of the clamping member 91 on the drain member 50, the drain member 50 is in a natural state, thus the drain channel 51 is in a conductive state, the drain member 50 is in a draining state, and the dirt can flow out from the drain port 511. In yet another embodiment, after the cleaning device 1000 enters the base station 3000, the force-applying member 3003 can move relative to the body 3001 to the position corresponding to the drain member 50, so that the force-applying member 3003 can cooperate with the clamping member 91. The force-applying component 3003 and the removable clamping component 91 exert external force on the sewage discharge component 50, so that the sewage discharge component 50 is in a natural state, the sewage discharge channel 51 is in a conductive state, the sewage discharge component 50 is in a sewage discharge state, and the sewage can flow out from the sewage discharge port 511.

[0305] Please see Figure 10 , Figures 23 to 24 In some embodiments, the base station 3000 further includes a driving structure connected to the force-applying member 3003. The driving structure is used to drive the force-applying member 3003 to apply or remove the applied external force to the sewage discharge member 50. Specifically, when the cleaning equipment 1000 enters the base station 3000 and the cleaning module 200 needs to discharge sewage, the driving member 80 drives the force-applying member 3003 to remove the external force applied to the sewage discharge member 50 by the clamping member 91, so that the sewage discharge channel 51 is in a conductive state. After the cleaning module 200 has finished discharging sewage, the driving member 80 drives the force-applying member 3003 to apply external force to the side wall of the sewage discharge member 50 through the clamping member 91, so that the sewage discharge channel 51 is in a closed state.

[0306] 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 200 relative to the body 300 of the cleaning equipment 1000 or the position of the cleaning module 200 relative to the base station 3000. The processing unit is used to determine whether the position of the cleaning module 200 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.

[0307] 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.

[0308] In one embodiment, when the position detection unit detects that the cleaning module 200 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 200 relative to the base station 3000 meets predetermined conditions, the processing unit controls the drive unit to drive the force-applying member 3003 to operate, so that the force-applying member 3003 removes the external force applied by the clamping member 91 to the sewage discharge member 50. When the position detection unit detects that the cleaning module 200 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 force-applying member 3003 to operate, and the force-applying member 3003 applies an external force to the clamping member 91, thereby the clamping member 91 applies an external force to the sewage discharge member 50.

[0309] In another embodiment, when the position detection unit detects that the cleaning module 200 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 200 is in the second relative position, the processing unit controls the drive unit to drive the force-applying member 3003 to operate, so that the force-applying member 3003 removes the external force applied by the clamping member 91 to the drain member 50. When the position detection unit detects that the cleaning module 200 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 200 is in the first relative position, the processing unit controls the drive unit to drive the force-applying member 3003 to operate, and the force-applying member 3003 applies an external force to the clamping member 91, thereby the clamping member 91 applies an external force to the drain member 50.

[0310] Please see Figure 25 Fifthly, embodiments of this application also provide a cleaning system 10000, which includes the cleaning device 1000 of the above embodiments and the base station 3000 of the above embodiments. The base station 3000 is used to maintain the cleaning device 1000 after it returns to its original position.

[0311] In the cleaning system 10000 of this application embodiment, the power system 20 switches between a first state and a second state. Dirt in the sewage channel 11 can enter and be stored in the receiving cavity 31. Liquid and dirt in the receiving cavity 31 can also be discharged outside the water system 100 through the sewage channel 11. When the external liquid cleaning sewage tank 30 is used, liquid in the receiving cavity 31 can flow through the sewage channel 11, cleaning the sewage channel 11. The liquid can also carry dirt from the sewage link 10 and discharge it outside the water system 100. Compared to the current water system 100, the sewage link 10 in the water system 100 of this application has higher cleaning efficiency, does not accumulate more dirt on the sewage link 10, and does not require manual cleaning, resulting in a better user experience.

[0312] Please see Figure 1 , Figure 17 and Figure 25 In some embodiments, the cleaning system 10000 further includes a clean water tank, which is disposed in at least one of the main body 201, the body 300 and the base station 3000. The clean water tank is connected to the inlet 331 of the wastewater tank 30 and is used to store cleaning liquid.

[0313] The cleaning liquid referred to here is the same as the "liquid" mentioned above, including clean water, cleaning solution, or a mixture containing cleaning solution. In one embodiment, a clean water tank is disposed on the body 201 of the cleaning module 200. The clean water tank here has the same structure as the clean water tank in the second aspect, and will not be described in detail here. In another embodiment, a clean water tank is disposed on the body 300 of the cleaning module 200. The clean water tank here has the same structure as the clean water tank in the third aspect, and will not be described in detail here.

[0314] In another embodiment, a clean water tank is installed at the base station 3000. The clean water tank on the base station 3000 can spray cleaning liquid to clean the cleaning equipment 1000, and the clean water tank is also used to replenish the clean water tank of the cleaning equipment 1000. When the wastewater tank 30 needs cleaning, the cleaning equipment 1000 returns to the base station 3000, and the clean water tank installed on the base station 3000 provides cleaning liquid to the wastewater tank 30. The clean water tank is connected to inlet 331, and the cleaning liquid in the clean water tank enters the channel 33 from inlet 331 and is sprayed from outlet 35 onto the inner wall of the wastewater tank 30 to clean the wastewater tank 30. When liquid and dirt in the wastewater tank 30 flow out from the connecting pipe 13, wastewater channel 11, and drain outlet 511, the cleaning liquid is also used to clean the connecting pipe 13, wastewater channel 11, and drain fitting 50.

[0315] Please see Figure 1 , Figure 17 and Figure 25 In some embodiments, the base station 3000 is provided with a third air pump; when the waste in the receiving cavity 31 is discharged from the sewage tank 30, the third air pump is used to pump air into the receiving cavity 31 through the inlet 331 or the second air hole of the sewage tank 30.

[0316] When the third air pump pumps air into the receiving cavity 31 through inlet 331, the third air pump is connected to inlet 331, and the gas enters the channel 33 from inlet 331 and passes through multiple outlets 35 into the receiving cavity 31 to increase the air pressure inside the receiving cavity 31. When the third air pump pumps air into the receiving cavity 31 through the second air hole (the second air hole here has the same structure as the second air hole in the second aspect, and the second air hole is opened in the sewage tank 30), the third air pump is connected to the second air hole and pumps air into the receiving cavity 31 through the second air hole.

[0317] When the liquid dissolves the dirt on the inner wall of the wastewater tank 30, the third air pump can pump air into the receiving cavity 31 through inlet 331 or the second air hole. When the third air pump pumps air into the receiving cavity 31 through inlet 331, the gas enters channel 33 and then enters the receiving cavity 31 through outlet 35, increasing the air pressure inside the receiving cavity 31. When the third air pump pumps air into the receiving cavity 31 through inlet 331 or the second air hole, the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31, allowing the liquid in the receiving cavity 31 to carry the dirt out through opening 32 to the outside of the wastewater tank 30. Furthermore, when the third air pump pumps air into the receiving cavity 31, all the liquid and dirt in the receiving cavity 31 can be discharged to the outside of the wastewater tank 30, leaving no residual liquid or dirt inside the wastewater tank 30, thus achieving a better cleaning effect for the wastewater tank 30.

[0318] With the first air pump 60 used to extract gas from the receiving cavity 31 and the third air pump used to pump air into the receiving cavity 31, the third air pump can quickly start and pump air into the receiving cavity 31 when waste needs to be discharged from the wastewater tank 30. The first air pump 60 does not need to switch from extraction to pumping mode; the use of the third air pump saves the time of this switching process, allowing liquid and waste to be quickly discharged from the opening 32 to the outside of the wastewater tank 30. Furthermore, the division of labor between the first and third air pumps is clear, resulting in a longer service life for both. Because the third air pump is located in the base station 3000, the cleaning device 1000 is lighter, making it easier to move when cleaning surfaces.

[0319] Please see Figure 1 , Figure 2 , Figure 3 and Figure 26 Sixthly, embodiments of this application also provide a method for cleaning a water system, the cleaning method being applied to the water system 100 described above, the cleaning method comprising:

[0320] 01: The power system 20 is in the first state, and waste enters the receiving cavity 31 through the sewage channel 11; and

[0321] 03: The power system 20 is in the second state, and the dirt in the containment cavity 31 is discharged to the outside of the water system 100 through the sewage channel 11.

[0322] Specifically, when the cleaning module 200 is cleaning the surface to be cleaned, the scraper 15 scrapes away the dirt from the mop 203, the power system 20 is in a first state, and the dirt from the mop 203 enters the wastewater channel 11 and then enters the receiving cavity 31 through the connecting pipe 13. At this time, the cleaning module 200 may include a controller. When the scraper 15 scrapes away the dirt from the mop 203, the controller controls the power system 20 to be in the first state, and the electronic control components of the power system 20 control the first air pump 60 to start, and the first air pump 60 draws gas from the receiving cavity 31. Since both the connecting pipe 13 and the sewage channel 11 are connected to the receiving cavity 31, when the first air pump 60 draws air from the receiving cavity 31, the air in the connecting pipe 13 and the sewage channel 11 is also drawn out by the first air pump 60. As a result, the connecting pipe 13, the sewage channel 11 and the receiving cavity 31 are all under negative pressure. The dirt entering the sewage channel 11 can be squeezed into the connecting pipe 13 and flow from the connecting pipe 13 into the receiving cavity 31, where the dirt is stored.

[0323] When the cleaning module 200 needs to discharge sewage, the controller can control the power system 20 to be in the second state. The electronic control components of the power system 20 can control the first air pump 60 to pump air into the receiving cavity 31, or the controller can control the receiving cavity 31 to be connected to the outside, so that the sewage in the receiving cavity 31 can enter the connecting pipe 13 through the opening 32 and flow out from the sewage channel 11 to the outside of the sewage link 10.

[0324] When the external liquid cleans the wastewater tank 30, and the liquid and waste in the receiving cavity 31 need to be discharged, the controller can control the power system 20 to enter a second state. The electrical control components of the power system 20 can control the first air pump 60 to pump air into the receiving cavity 31, or the controller can control the receiving cavity 31 to connect to the outside, so that the liquid and waste in the receiving cavity 31 can enter the connecting pipe 13 through the opening 32 and flow out from the wastewater channel 11 to the outside of the wastewater link 10. When the liquid passes through the connecting pipe 13 and the wastewater channel 11, the liquid can flush the connecting pipe 13 and the wastewater channel 11, and the liquid can carry the wastewater in the connecting pipe 13 and the wastewater channel 11 out to the outside of the wastewater link 10. When the external liquid cleans the wastewater tank 30, the liquid also cleans the connecting pipe 13 and the wastewater channel 11, so that dirt does not accumulate in the connecting pipe 13 and the wastewater channel 11, and the connecting pipe 13 and the wastewater channel 11 can be kept in a relatively clean state.

[0325] Please see Figure 1 , Figure 2 and Figure 27 In some embodiments, 03: the waste in the receiving cavity 31 is discharged to the outside of the water system 100 through the sewage channel 11, including:

[0326] 031: The cleaning liquid enters the receiving cavity 31 through the inlet 331 of the sewage tank 30;

[0327] 033: Immerse the receiving cavity 31 in cleaning liquid for a predetermined time; and

[0328] 035: The waste in the receiving cavity 31 is discharged to the outside of the sewage link 10 through the connecting pipe 13 and sewage channel 11 of the sewage link 10.

[0329] When the wastewater tank 30 requires cleaning, cleaning liquid enters the receiving cavity 31 through inlet 331 to clean the inner wall of the wastewater tank 30. The cleaning liquid flows through various points on the inner wall of the wastewater tank 30, carrying away dirt and debris, thus keeping the wastewater tank 30 relatively clean and eliminating the need for manual cleaning. After the cleaning liquid enters the receiving cavity 31, it soaks the cavity for a predetermined time, dissolving stubborn stains on the inner wall and achieving a good cleaning effect. The predetermined time refers to the time required for the cleaning liquid to fully dissolve the dirt on the inner wall of the wastewater tank 30. The predetermined time is the time from when the receiving cavity 31 is filled with cleaning liquid until the liquid and dirt begin to drain from the wastewater tank 30. For example, the predetermined time could be 3 minutes, 5 minutes, or 10 minutes. For example, if the predetermined duration is 5 minutes, the time required for the cleaning liquid to fully dissolve the dirt on the inner wall of the wastewater tank 30 is 5 minutes. Also, the time from when the cleaning liquid fills the receiving cavity 31 to when the liquid and dirt begin to drain from the wastewater tank 30 is 5 minutes.

[0330] After the cleaning liquid soaks the receiving cavity 31 for a predetermined time, the liquid and dirt in the receiving cavity 31 flow out from the opening 32 and flow into the connecting pipe 13 and the sewage channel 11, where the liquid cleans the connecting pipe 13 and the sewage channel 11. When the cleaning liquid in the receiving cavity 31 flows out from the opening 32, the water pressure of the cleaning liquid flowing out from the opening 32 is relatively high, which is beneficial for cleaning the connecting pipe 13 and the sewage channel 11, resulting in a better cleaning effect. After cleaning the connecting pipe 13 and the sewage channel 11, the liquid and dirt flow into the drain component 50. At this time, the drain component 50 is in the draining state, and the liquid and dirt flow out from the drain channel 51 to the outside of the cleaning module 200.

[0331] Please see Figure 5 , Figure 6 , Figure 7 and Figure 28 In some embodiments, 031: introducing cleaning liquid into receiving cavity 31 via inlet 331 includes:

[0332] 0313: The cleaning liquid enters the wastewater tank 30 through the inlet 331 and the channel 33, and is sprayed from the outlet 35 of the wastewater tank 30 in a direction away from the center of the cross-section of the wastewater tank 30 toward the inner wall of the wastewater tank 30; and

[0333] 0315: The cleaning liquid flows down the inner wall of the receiving cavity 31 and is stored in the receiving cavity 31.

[0334] Please see Figure 5 , Figure 6 , Figure 7 and Figure 28 In some embodiments, 031: the cleaning liquid is introduced into the receiving cavity 31 via the inlet 331, and the method further includes:

[0335] 0311: Draw the cleaning liquid from the clean water tank and let the cleaning liquid enter the channel 33 from the inlet 331.

[0336] Since the outlet 35 is located at the top of the wastewater tank 30, when the cleaning liquid is sprayed from the outlet 35 towards the inner wall of the top of the wastewater tank 30 in a direction away from the center of the cross-section of the wastewater tank 30, the cleaning liquid will flow down the inner wall of the wastewater tank 30 due to gravity. As the cleaning liquid flows down the inner wall of the wastewater tank 30 from the top, the cleaning liquid can rinse various parts of the inner wall of the wastewater tank 30.

[0337] In one embodiment, when the wastewater tank 30 needs cleaning, a clean water tank provided in the main body 201 provides cleaning liquid to the wastewater tank 30. The clean water tank may be equipped with a water pump. When the wastewater tank 30 needs cleaning, the controller can control the water pump to start, and the water pump draws the cleaning liquid from the clean water tank so that the cleaning liquid enters the channel 33 through the inlet 331. The cleaning liquid is sprayed from the outlet 35 in a direction away from the center of the cross-section of the wastewater tank 30 onto the inner wall of the wastewater tank 30. The cleaning liquid entering the receiving cavity 31 is stored in the receiving cavity 31 and soaks the receiving cavity 31.

[0338] In another embodiment, when the wastewater tank 30 needs cleaning, a clean water tank located in the body 300 of the cleaning equipment 1000 provides cleaning liquid to the wastewater tank 30. The clean water tank may be equipped with a water pump. When the wastewater tank 30 needs cleaning, the clean water tank is connected to the inlet 331, and the controller can control the water pump to start. The water pump draws the cleaning liquid from the clean water tank, allowing the cleaning liquid to enter the channel 33 through the inlet 331. The cleaning liquid can be sprayed from the outlet 35 in a direction away from the center of the cross-section of the wastewater tank 30 onto the inner wall of the wastewater tank 30. The cleaning liquid entering the receiving cavity 31 is stored in the receiving cavity 31 and soaks the receiving cavity 31.

[0339] In another embodiment, when the wastewater tank 30 needs cleaning, a clean water tank installed in the base station 3000 provides cleaning liquid to the wastewater tank 30. The clean water tank may be equipped with a water pump. When the wastewater tank 30 needs cleaning, the clean water tank is connected to the inlet 331. The controller of the cleaning module 200 or the controller of the base station 3000 can control the water pump to start. The water pump draws the cleaning liquid from the clean water tank, so that the cleaning liquid enters the channel 33 through the inlet 331. The cleaning liquid can be sprayed from the outlet 35 in a direction away from the center of the cross-section of the wastewater tank 30 onto the inner wall of the wastewater tank 30. The cleaning liquid entering the receiving cavity 31 is stored in the receiving cavity 31 and soaks the receiving cavity 31.

[0340] In another embodiment, when the wastewater tank 30 needs cleaning, an external water source provides cleaning liquid to the wastewater tank 30. The external water source may be equipped with a water pump. When the wastewater tank 30 needs cleaning, the external water source is connected to the inlet 331, and the controller controls the water pump to start. The water pump draws the cleaning liquid from the external water source, allowing the cleaning liquid to enter the channel 33 through the inlet 331. The cleaning liquid can be sprayed from the outlet 35 in a direction away from the center of the cross-section of the wastewater tank 30 onto the inner wall of the wastewater tank 30. The cleaning liquid entering the receiving cavity 31 is stored in the receiving cavity 31 and soaks the receiving cavity 31.

[0341] Please see Figure 1 , Figure 2 , Figure 5 and Figure 29 In some embodiments, 033: immersing the receiving cavity 31 in a cleaning liquid for a predetermined period of time includes:

[0342] 0331: The first air pump 60 of the power system 20 is used to extract the gas in the receiving cavity 31, so that the cleaning liquid is stored in the receiving cavity 31.

[0343] In one embodiment, when the wastewater tank 30 needs cleaning, the controller first activates the water pump to pump cleaning liquid into the channel 33, thereby spraying the cleaning liquid from the outlet 35 in a direction away from the center of the cross-section of the wastewater tank 30 toward the inner wall of the wastewater tank 30. The controller then activates the first air pump 60, which draws gas from the receiving cavity 31 through the first air hole 34, so that the air pressure inside the receiving cavity 31 is lower than the air pressure outside the receiving cavity 31, thereby allowing the cleaning liquid to be stored in the receiving cavity 31 and soak the inner wall of the wastewater tank 30.

[0344] In another embodiment, when the wastewater tank 30 needs cleaning, the controller first activates the first air pump 60, which draws gas from the receiving cavity 31 through the first air port 34. The controller then activates the water pump to pump cleaning liquid into the channel 33, whereby the cleaning liquid is sprayed from the outlet 35 along a direction away from the center of the cross-section of the wastewater tank 30 towards the inner wall of the wastewater tank 30. Because the air pressure inside the receiving cavity 31 is lower than the air pressure outside the receiving cavity 31, the cleaning liquid can be stored in the wastewater tank 30 and soak the inner wall of the wastewater tank 30.

[0345] Please see Figure 1 , Figure 2 , Figure 5 and Figure 30 In some embodiments, 035: the contaminants in the receiving cavity 31 are discharged outside the sewage link 10 via the connecting pipe 13 and the sewage channel 11, including:

[0346] 0351: The air pump assembly 60 of the power system 20 pumps air into the receiving cavity 31, so that the liquid and dirt in the receiving cavity 31 are discharged to the outside of the sewage link 10.

[0347] In one embodiment, after the cleaning liquid has soaked the receiving cavity 31 for a predetermined period, the liquid and contaminants in the receiving cavity 31 need to be discharged from the wastewater tank 30. At this time, the controller can control the first air pump 60 to switch from extracting gas from the receiving cavity 31 to pumping air into the receiving cavity 31. The first air pump 60 pumps air into the receiving cavity 31 through the first air hole 34 or the second air hole, so that the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31. Thus, the liquid and contaminants in the receiving cavity 31 can pass through the connecting pipe 13 and the wastewater channel 11, and be discharged from the sewage discharge channel 51 to the outside of the cleaning module 200. When the first air pump 60 pumps air into the receiving cavity 31, the water pressure of the liquid and contaminants flowing from the receiving cavity 31 into the connecting pipe 13 and the wastewater channel 11 is relatively high, so the cleaning effect of the liquid on the connecting pipe 13 and the wastewater channel 11 is better.

[0348] In another embodiment, after the cleaning liquid has soaked the receiving cavity 31 for a predetermined period, the liquid and dirt in the receiving cavity 31 need to be discharged from the wastewater tank 30. At this time, the controller can control the second air pump to start. The second air pump pumps air into the receiving cavity 31 through the second air hole, so that the air pressure inside the receiving cavity 31 is greater than the air pressure outside the receiving cavity 31. As a result, the liquid and dirt in the receiving cavity 31 can pass through the connecting pipe 13 and the wastewater channel 11, and be discharged from the drain port 511 to the outside of the cleaning module 200. When the second air pump pumps air into the receiving cavity 31, the water pressure of the liquid and dirt flowing from the receiving cavity 31 into the connecting pipe 13 and the wastewater channel 11 is relatively high, so the cleaning effect of the liquid on the connecting pipe 13 and the wastewater channel 11 is better.

[0349] Please see Figure 1 , Figure 10 , Figure 15 , Figure 16 and Figure 31 In some embodiments, 0351: draining the liquid and waste in the receiving cavity 31 to the outside of the sewage link 10 includes:

[0350] 03511: When the cleaning equipment 1000 moves to the designated sewage discharge position, the sewage discharge component 50 is switched to the sewage discharge state; and

[0351] 03515: When the cleaning equipment 1000 has completed the sewage discharge, control the sewage discharge component 50 to switch to the non-discharge state.

[0352] When the cleaning equipment 1000 moves to the designated discharge position, the drive unit 80 or drive unit controls the discharge component 50 to switch from a non-discharge state to a discharge state. Wastewater in the receiving cavity 31 flows through the connecting pipe 13 and the sewage channel 11, enters the discharge channel 51 from the inlet 513, and finally exits from the discharge port 511 to the outside of the cleaning equipment 1000. When the cleaning equipment 1000 completes discharge, the drive unit 80 or drive unit controls the discharge component 50 to switch from a discharge state to a non-discharge state, thus preventing the wastewater in the receiving cavity 31 from being discharged from the discharge port 511 to the outside of the cleaning equipment 1000.

[0353] Please see Figure 1 , Figure 10 and Figure 32 In some embodiments, the discharge component 50 can rotate relative to the sewage tank 30 to switch between a non-discharge state and a discharge state. When the discharge component 50 is in the discharge state, the height of the discharge port 511 is lower than the height of the discharge port 511 when the discharge component 50 is in the non-discharge state. 03511: When the cleaning equipment 1000 moves to the designated discharge position, controlling the discharge component 50 to switch to the discharge state includes:

[0354] 03513: Control the sewage discharge component 50 to rotate relative to the sewage tank 30 in the first direction.

[0355] When the cleaning equipment 1000 needs to discharge wastewater, the drive unit 80 can drive the discharge unit 50 to rotate relative to the wastewater tank 30 in a first direction. The drive unit 80 is connected to the force-receiving part 53 of the discharge unit 50, and the drive unit 80 applies an external force to the force-receiving part 53, so that the discharge unit 50 can rotate in the first direction. In the height direction H of the wastewater tank 130, the height of the discharge port 511 gradually decreases. When the discharge port 511 is lower than the inlet port 513, or when the discharge port 511 is flush with the inlet port 513, the discharge unit 50 stops rotating, and at this time the discharge unit 50 switches from the non-discharge state to the discharge state. The waste in the receiving cavity 31 can pass through the connecting pipe 13, the wastewater channel 11 and the discharge channel 51, and be discharged from the discharge port 511 to the outside of the cleaning equipment 1000.

[0356] In another embodiment, when the cleaning equipment 1000 needs to be drained, when the cleaning equipment 1000 is docked at the base station docking position, the cleaning module of the cleaning equipment 1000 is controlled to move forward relative to the body of the cleaning equipment 1000 along the width direction of the body, so that the cleaning module reaches a second relative position, so that the draining component cooperates with the force-applying component of the base station 3000 to drive the draining component to rotate in the first direction. This switches the draining component from a non-draining state to a draining state, realizing the draining of the cleaning equipment 1000 at the base station 3000. Please refer to [link to relevant documentation]. Figure 1 , Figure 10 and Figure 32 In some embodiments, 03515: When the cleaning equipment 1000 has completed the sewage discharge, the sewage discharge component 50 is switched to a non-discharge state, including:

[0357] 03517: Control the sewage discharge component 50 to rotate relative to the sewage tank 30 in the second direction.

[0358] In one embodiment, after the cleaning equipment 1000 has completed its wastewater discharge, the drive member 80 can drive the discharge member 50 to rotate relative to the wastewater tank 30 in a second direction. The drive member 80 is connected to the force-receiving part 33 of the discharge member 50, and the drive member 80 applies an external force to the force-receiving part 53, thereby allowing the discharge member 50 to rotate in the second direction. In the height direction H of the wastewater tank 30, the height of the discharge port 511 gradually increases. When the discharge port 511 is higher than the inlet port 513, the discharge member 50 stops rotating, and at this time, the discharge member 50 switches from the discharge state to the non-discharge state. The waste in the receiving cavity 31 cannot be discharged from the discharge port 511 to outside the cleaning equipment 1000.

[0359] In another embodiment, after the cleaning equipment 1000 has completed its wastewater discharge, the drive member 80 removes the external force applied to the discharge member 50, and the reset member 70 can drive the discharge member 50 to rotate in the second direction. In the height direction H of the wastewater tank 30, the height of the discharge port 511 gradually increases. When the discharge port 511 is higher than the inlet port 513 and the reset member 70 returns to its natural state, the discharge member 50 stops rotating, and at this time, the discharge member 50 switches from the discharge state to the non-discharge state. The waste in the receiving cavity 31 cannot be discharged from the discharge port 511 to outside the cleaning equipment 1000.

[0360] In another embodiment, after the cleaning equipment 1000 has completed its wastewater discharge, the drive member 80 removes the external force applied to the wastewater discharge member 50, and the reset member 70 can drive the wastewater discharge member 50 to rotate in the second direction. Specifically, when the cleaning equipment 1000 is docked at the base station docking position, the cleaning module of the cleaning equipment 1000 is controlled to move in the opposite direction of the body of the cleaning equipment 1000 along the width direction of the body, so that the cleaning module reaches the first relative position, so that the wastewater discharge member 50 is moved away from the force-applying member of the base station 3000, causing the wastewater discharge member 50 to rotate in the second direction. In this way, the wastewater discharge member 50 can be switched from the wastewater discharge state to the non-wastewater discharge state, ensuring that the wastewater in the wastewater tank 30 of the cleaning equipment 1000 will not flow out.

[0361] Please see Figure 1 , Figure 10 and Figure 33 In some embodiments, 03511: when the cleaning equipment 1000 moves to the designated sewage discharge location, it includes:

[0362] 03512: Cleaning equipment 1000 is moved to base station 3000's docking position;

[0363] 03513: Controlling the rotation of the sewage discharge component 50 relative to the sewage tank 30 in a first direction includes:

[0364] 03514: The cleaning module 200 of the control cleaning equipment 1000 moves in the positive direction of the width of the body 300 of the control cleaning equipment 1000 to a second relative position, so that the sewage discharge component 50 cooperates with the force application component 3003 of the base station 3000 to drive the sewage discharge component 50 to rotate in the first direction.

[0365] When the cleaning equipment 1000 needs to be drained, the cleaning equipment 1000 first moves to the docking position of the base station 3000. The controller controls the cleaning module 200 to move relative to the body 300 to the second relative position. At this time, the draining component 50 and the force-applying component 3003 start to cooperate. The draining component 50 rotates in the first direction, so that the dirt can flow into the base station.

[0366] Please see Figure 1 , Figure 10 and Figure 33In some embodiments, 03515: when the cleaning equipment 1000 has completed the discharge of wastewater, it includes:

[0367] 03516: Cleaning equipment 1000 is moved away to base station 3000's docking position;

[0368] 03517: Controlling the rotation of the sewage discharge component 50 relative to the sewage tank 30 in a second direction includes:

[0369] 03518: The cleaning module 200 of the control cleaning equipment 1000 moves in the opposite direction of the body 300 of the cleaning equipment 1000 along the width direction of the body 300 to reach a first relative position, so that the sewage discharge component 50 moves away from the force application component 3003 of the base station 3000 so that the sewage discharge component 50 rotates in the second direction.

[0370] When the cleaning equipment 1000 has finished discharging the sewage, the cleaning equipment 1000 first moves away from the docking position of the base station 3000. The controller controls the cleaning module 200 to move relative to the body 300 to the first relative position. At this time, the sewage discharge component 50 is separated from the force application component 3003, and the sewage discharge component 50 can rotate in the second direction. The sewage discharge component 50 is in the undischarged state.

[0371] Please see Figure 15 , Figure 16 and Figure 34 In some embodiments, the drain component 50 can deform under external force on the outside of the drain channel 51 to switch between a non-drainage state and a drainage state. When the drain component 50 is in the drainage state, the drain channel 51 is in a conductive state; when the drain component 50 is in the non-drainage state, the drain channel 51 is in a closed state. 03511: When the cleaning equipment 1000 moves to the designated drainage position, controlling the drain component 50 to switch to the drainage state includes:

[0372] 03519: Control the sewage discharge channel 51 to be in the conductive state.

[0373] When the cleaning equipment 1000 needs to discharge wastewater, the drive unit can drive the force-applying component 90 to change the external force applied to the discharge component 50. The discharge component 50 can deform under the force, and the drive unit drives the force-applying component 80 to remove the external force applied to the discharge component 50. The discharge component 50 is in its natural state, so the discharge channel 51 is in the conductive state, and the discharge component 50 is in the discharge state. The waste in the receiving cavity 31 can pass through the connecting pipe 13, the sewage channel 11, and the discharge channel 51, and be discharged from the discharge port 511 to the outside of the cleaning equipment 1000.

[0374] Please see Figure 15 , Figure 16 and Figure 34In some embodiments, 03515: When the cleaning equipment 1000 has completed the sewage discharge, the sewage discharge component 50 is switched to a non-discharge state, including:

[0375] 03520: Control the sewage discharge channel 51 to be in the closed state.

[0376] After the cleaning equipment 1000 has completed its wastewater discharge, the drive unit can drive the force-applying component 90 to change the external force applied to the wastewater discharge component 50. The drive unit drives the force-applying component 90 to apply an external force to the wastewater discharge component 50, causing it to deform, thereby closing the wastewater discharge channel 51 and placing the wastewater discharge component 50 in a wastewater discharge state. Waste in the receiving cavity 31 cannot be discharged from the wastewater discharge port 511 to the outside of the cleaning equipment 1000.

[0377] In the cleaning method of the cleaning module according to the embodiments of this application, the power system 20 switches between a first state and a second state. Dirt in the sewage channel 11 can enter and be stored in the receiving cavity 31. Liquid and dirt in the receiving cavity 31 can also be discharged outside the water system 100 through the sewage channel 11. When the external liquid cleans the sewage tank 30, liquid in the receiving cavity 31 can flow through the sewage channel 11, cleaning the sewage channel 11. The liquid can also carry dirt from the sewage link 10 and discharge it outside the water system 100. Compared to the current water system 100, the sewage link 10 in the water system 100 of this application has higher cleaning efficiency, does not accumulate more dirt on the sewage link 10, and does not require manual cleaning, resulting in a better user experience.

[0378] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0379] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
