[0001] The present application relates to the field of cleaning equipment, and in particular to a recycling component, a cleaning module, a cleaning device, a cleaning system and a cleaning method. Background Art

[0002] After the mopping element of the cleaning module cleans the surface, it will carry dirty water. If the mopping element, laden with dirty water, continues to clean the surface, the cleaning effect will be poor. Therefore, a cleaning robot can be equipped with a dirty water tank to recover the dirty water from the mopping element, thereby improving the cleaning effect of the mopping element on the surface. Currently, dirty water tanks are typically equipped with a self-cleaning function, which automatically cleans the tank when the dirty water is discharged. However, the current self-cleaning function of the dirty water tank does not provide a good cleaning effect.

DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below. Implementations of the embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0030] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] After the mopping and wiping parts of the cleaning module clean the surface to be cleaned, dirty water will be left on the mopping and wiping parts. If the mopping and wiping parts with dirty water continue to clean the surface to be cleaned, the cleaning effect of the mopping and wiping parts will be poor. Therefore, the cleaning robot may be provided with a sewage tank, which is used to recycle the dirty water on the mopping and wiping parts, thereby improving the cleaning effect of the mopping and wiping parts on the surface to be cleaned. Currently, sewage tanks are usually provided with a self-cleaning function, that is, when the sewage in the sewage tank is discharged, the sewage tank can be automatically cleaned. However, the self-cleaning function of the current sewage tank has a poor cleaning effect on the sewage tank. To solve this problem, the present application provides a recovery component, a cleaning module (shown in Figure 1), a cleaning device 1000 (shown in Figure 7), a cleaning system 10000 (shown in Figure 8) and a cleaning method.

[0032] Referring to Figures 1, 2, 3, and 5, in a first aspect, embodiments of the present application provide a recovery assembly 100 comprising a wastewater tank 10 and a storage element 30. The wastewater tank 10 comprises a receiving chamber 11. The storage element 30 is mounted within the receiving chamber 11 and includes a storage chamber 31 for storing waste. The storage element 30 is deformable to switch between a first state and a second state. When the storage element 30 is in the first state, the volume of the storage chamber 31 is smaller than when the storage element 30 is in the second state.

[0033] In a second aspect, an embodiment of the present application provides a cleaning module including a main body 20 , a wiping member, and a recovery assembly 100 , wherein the wiping member and the recovery assembly 100 are both disposed on the main body 20 .

[0034] Specifically, please refer to Figure 7. The recycling component 100 is a structure applied to the cleaning module. When the cleaning module cleans the surface to be cleaned, the recycling component 100 is used to recycle the dirt when the cleaning module cleans the surface to be cleaned, thereby preventing the dirt from falling onto the surface to be cleaned. The cleaning module is a structure applied to the cleaning device 1000, and the cleaning module is used to clean the surface to be cleaned. The surface to be cleaned can be, but is not limited to, a floor, a marble surface, or a glass surface. This application is explained by taking the floor as an example of the surface to be cleaned. The cleaning device 1000 is a device for cleaning the surface to be cleaned. For example, the cleaning device 1000 may include a sweeping robot, a mopping robot, a sweeping and mopping robot, a handheld floor scrubber, etc. A sweeping robot can be used to clean the surface to be cleaned, and a mopping robot can be used to wipe and clean the surface to be cleaned. A 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 the surface to be cleaned, and a sweeping and mopping robot can also be used to wipe and clean the surface to be cleaned. A handheld floor scrubber can use a roller or track to wet clean the surface to be cleaned (wet cleaning means wetting the roller or track to wipe the floor and recover mixed solid and liquid waste). The cleaning device 1000 of this application is described using a sweeping and mopping robot as an example.

[0035] In some embodiments, the cleaning device 1000 may include a crawler-type cleaning robot or a drum-type cleaning robot. When the cleaning device 1000 is a crawler-type cleaning robot, the wiping member of the cleaning device 1000 is a crawler-type wiping member. When the cleaning device 1000 is a drum-type cleaning robot, the wiping member of the cleaning device 1000 is a drum-type wiping member. Both the crawler-type wiping member and the drum-type wiping member can clean the surface to be cleaned by rotating, and the cleaning device 1000 has a better cleaning effect on the surface to be cleaned. This application is described by taking the cleaning device 1000 as a crawler-type cleaning robot as an example. When the cleaning device 1000 is a crawler-type cleaning robot, while the crawler-type wiping member rotates to clean the surface to be cleaned, the cleaning module can clean the wiping member, so that the wiping member can remain in a relatively clean state, and the cleaning module has a better cleaning effect on the surface to be cleaned.

[0036] Referring to Figures 1 and 2 , the sewage tank 10 is a structure for housing the storage element 30. The sewage tank 10 can be mounted on the main body 20 of the cleaning module. When mounted on the main body 20 of the cleaning module, the sewage tank 10 can be detachably or non-detachably connected to the main body 20. Removable connection methods include, but are not limited to, threaded connections, screw connections, or snap connections, while non-detachable connection methods include, but are not limited to, welding, gluing, or interference fit. When the sewage tank 10 is detachably connected to the main body 20, it can be easily removed from the main body 20 for repair in the event of damage. When the sewage tank 10 is non-detachably connected to the main body 20, the sewage tank 10 and the main body 20 can be integrally formed, simplifying the manufacturing steps of the cleaning module. The accommodating cavity 11 is a spatial structure for mounting the storage element 30. The volume of the accommodating cavity 11 can be greater than or equal to the volume of the storage element 30 when in the second state.

[0037] The sewage tank 10 may be 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. Metal provides increased strength and a longer service life. Plastic reduces material costs and reduces weight, making it easier to transport and handle. The horizontal cross-section of the sewage tank 10 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0038] Please refer to FIG. 2. When the cleaning module cleans the surface to be cleaned, the recycling component 100 can clean the wiping member and recycle the dirt on the wiping member. When the recycling component 100 cleans the wiping member, the dirt scraping member of the recycling component 100 can scrape off the dirt on the wiping member. The storage member 30 is used to store the dirt scraped off by the dirt scraping member to prevent the dirt from falling onto the surface to be cleaned. The dirt here may include liquid sewage and solid dirt. The storage member 30 and the sewage tank 10 may be detachably connected. In the case where the storage member 30 is damaged, the storage member 30 can be detached from the sewage tank 10 for repair or replacement.

[0039] Please refer to FIGS. 3 to 6. In some embodiments, the storage member 30 may be an elastomer. The material of the elastic storage member 30 includes but is not limited to rubber, latex, or elastic plastic, etc. Thus, the storage member 30 can switch between a first state (shown in FIGS. 3 and 4) and a second state (shown in FIGS. 5 and 6) by deforming. The first state of the storage member 30 may be the natural state of the storage member 30, and the second state of the storage member 30 may be an expanded state compared to the natural state. Exemplarily, when the storage member 30 is in the first state, the volume of the storage cavity 31 is A. When the storage member 30 is in the second state, the volume of the storage cavity 31 is B, and the relationship between A and B can satisfy: A < B. When the storage member 30 needs to store dirt, the storage member 30 can be in the second state, so that the volume of the storage cavity 31 is larger, and the storage cavity 31 can store more dirt. When the cleaning device 1000 cleans the surface to be cleaned, the dirt on the wiping member continuously enters the storage cavity 31 and is stored in the storage cavity 31. When the storage cavity 31 can store more dirt, the cleaning device 1000 does not need to frequently move to a designated position to discharge the dirt, and the cleaning efficiency of the cleaning device 1000 for cleaning the surface to be cleaned is relatively high.

[0040] When the wastewater in the storage chamber 31 needs to be drained outside the storage element 30, the storage element 30 can be switched from the second state to the first state. In this state, the volume of the storage chamber 31 decreases, and the storage element 30 can squeeze the wastewater inside, allowing it to be quickly drained outside. As the wastewater is drained from the storage chamber 31, some of it may remain on the inner sidewalls of the storage element 30. When the storage element 30 is switched from the second state to the first state, the volume of the storage chamber 31 decreases rapidly, allowing some of the wastewater to easily fall off the inner sidewalls of the storage element 30, facilitating cleaning of the storage element 30. When the storage element 30 is in the second state, the volume of the storage chamber 31 is relatively large. When the storage element 30 needs to be cleaned, external liquid entering the storage chamber 31 has difficulty flowing to all locations on the inner sidewalls of the storage element 30, resulting in a poor cleaning effect on the storage element 30. In this application, the storage element 30 is cleaned after it has been switched from the second state to the first state. At this time, the volume of the storage chamber 31 is relatively small. When external liquid enters the storage chamber 31, the liquid can flow through various locations on the inner wall of the storage element 30, carrying dirt from the inner wall of the storage element 30 out of the storage element 30, thereby improving the cleaning effect of the storage element 30. The liquid here can be, but is not limited to, clean water, cleaning liquid, or a mixed liquid containing cleaning liquid.

[0041] In the recovery assembly 100 of the embodiment of the present application, the storage element 30 can switch between a first state and a second state, and the volume of the storage chamber 31 when the storage element 30 is in the first state is smaller than the volume of the storage chamber 31 when the storage element 30 is in the second state. When the storage element 30 needs to store dirt, the storage element 30 can be in the second state. When the storage element 30 needs to be cleaned, the storage element 30 can be switched to the first state. Because the volume of the storage chamber 31 is smaller when the storage element 30 is in the first state, when the storage chamber 31 is cleaned, liquid entering the storage chamber 31 can more easily reach various locations within the storage chamber, thereby improving the cleaning efficiency within the storage chamber and reducing blind spots in cleaning. This makes cleaning the storage element 30 simpler and provides a better cleaning effect.

[0042] The recycling component 100 is further described below with reference to the accompanying drawings.

[0043] 3 to 6 , in some embodiments, when the storage element 30 is in the first state, the storage element 30 is spaced apart from at least one side wall of the sewage tank 10 ; and when the storage element 30 is in the second state, the storage element 30 is in contact with at least one side wall of the sewage tank 10 .

[0044] When the storage element 30 is in the first state, it is in a natural state, and the volume of the storage chamber 31 is at its minimum capacity. This allows external liquid to flow through various locations on the inner sidewalls of the storage element 30, effectively cleaning the storage element 30. When the storage element 30 is in the first state, its volume is significantly smaller than that of the sewage tank 10. When installed in the accommodating chamber 11, the storage element 30 can be spaced apart from multiple sidewalls of the sewage tank 10.

[0045] If the horizontal cross-section of the sewage tank 10 is circular (the sewage tank 10 is a cylindrical structure), the sewage tank 10 includes three sidewalls (a top wall, a bottom wall, and a sidewall). In this case, when the storage element 30 is in the first state, the storage element 30 may be spaced from one of the sidewalls of the sewage tank 10, two of the sidewalls, or all three of the sidewalls. If the horizontal cross-section of the sewage tank 10 is quadrilateral (the sewage tank 10 is a prismatic structure), the sewage tank 10 includes six sidewalls (the six faces of the prism). In this case, when the storage element 30 is in the first state, the storage element 30 may be spaced from one of the sidewalls of the sewage tank 10, two of the sidewalls, three of the sidewalls, or all six of the sidewalls.

[0046] When the storage element 30 is in the second state, it is in an expanded state. When the storage element 30 contacts at least one sidewall of the sewage tank 10, the volume of the storage chamber 31 is increased, allowing it to hold a larger amount of waste. Preferably, the storage element 30 can completely fill the accommodating chamber 11. In this case, the storage element 30 contacts all sidewalls of the sewage tank 10, and the volume of the storage chamber 31 reaches its maximum capacity, allowing it to hold a larger amount of waste.

[0047] Please refer to Figures 3 to 6. In some embodiments, the space in the accommodating chamber 11 except the storage element 30 is the accommodating space 13; when the storage element 30 is in the first state, the air pressure in the storage chamber 31 is less than or equal to the air pressure in the accommodating space 13; when the storage element 30 is in the second state, the air pressure in the storage chamber 31 is greater than the air pressure in the accommodating space 13.

[0048] Specifically, the volume of the storage chamber 31 plus the volume of the accommodating space 13 equals the volume of the accommodating chamber 11. When the storage element 30 is in the first state, the volume of the storage chamber 31 is small, and the volume of the accommodating space 13 is large. When the storage element 30 is in the second state, the volume of the storage chamber 31 is large, and the volume of the accommodating space 13 is small.

[0049] When the air pressure in the storage chamber 31 is lower than the air pressure in the storage space 13, the air pressure in the storage space 13 compresses the storage element 30, resulting in a smaller volume for the storage element 30 and a smaller capacity for the storage chamber 31. When external liquid enters the storage chamber 31 to clean the inner wall of the storage element 30, the liquid can flow through various locations on the inner wall of the storage chamber 31, effectively cleaning the storage element 30. When the air pressure in the storage chamber 31 is equal to the air pressure in the storage space 13, the storage element 30 is in a natural state. In this natural state, the volume of the storage element 30 is smaller, resulting in a smaller volume for the storage chamber 31. When external liquid enters the storage chamber 31 to clean the inner wall of the storage element 30, the liquid can flow through various locations on the inner wall of the storage chamber 31, effectively cleaning the storage element 30.

[0050] When the air pressure in the storage chamber 31 exceeds the air pressure in the storage space 13, the storage element 30 expands toward the storage space 13. When the storage chamber 31 contacts all sidewalls of the sewage tank 10, the storage element 30 cannot expand further. At this point, the storage element 30 is in the second state, with the storage chamber 31 having a larger volume, allowing it to hold more waste.

[0051] Referring to Figures 3 and 4 , in some embodiments, when the storage element 30 is in the first state, the storage element 30 is tubular. In one example, the cross-sectional area of ​​each location within the storage element 30 is equal, and the cross-sectional area of ​​each location within the storage element 30 is relatively small. When external liquid enters the storage chamber 31, the liquid can easily and smoothly flow into each location on the inner sidewall of the storage element 30, flushing the entire area, effectively cleaning the storage element 30. In this case, the structure of the storage element 30 is relatively regular, making its processing relatively simple. In another example, in the direction of liquid flow within the storage chamber 31, the cross-sectional area of ​​the downstream storage element 30 is smaller than or equal to the cross-sectional area of ​​the upstream storage element 30. When external liquid flows within the storage chamber 31, the liquid more easily contacts each location on the inner sidewall of the storage element 30, thereby flushing the entire area, effectively cleaning the storage element 30.

[0052] Referring to Figures 5 and 6 , in other embodiments, when the storage element 30 is in the second state, the shape of the storage element 30 matches the shape of the receiving chamber 11. Because the storage element 30 is an elastic body, its shape is variable. In the second state, the storage element 30 can contact all sidewalls of the sewage tank 10, thereby matching the shape of the receiving chamber 11. At this point, the storage element 30 nearly fills the receiving chamber 11. When the storage element 30 nearly fills the receiving chamber 11, the volume of the storage chamber 31 reaches its maximum capacity, allowing the storage element 30 to hold a larger amount of waste.

[0053] Referring to Figures 3 to 6 , in some other embodiments, when the storage element 30 is in a first state, the storage element 30 is tubular; and when the storage element 30 is in a second state, the shape of the storage element 30 matches the shape of the accommodating chamber 11. When the storage element 30 needs to store waste, the storage element 30 can be in the second state. In this state, the volume of the storage chamber 31 reaches its maximum capacity, allowing the storage element 30 to store a large amount of waste. When the storage element 30 needs to be cleaned, the storage element 30 can be in the first state. In this state, external liquid can easily and smoothly flow into various locations on the inner sidewall of the storage element 30 to flush the various locations on the inner sidewall of the storage element 30, effectively cleaning the storage element 30.

[0054] Referring to Figures 1, 2, 3 and 5, in some embodiments, the sewage tank 10 is provided with a first opening 14 and a second opening 15 spaced apart from each other, and both ends of the storage element 30 are connected to the first opening 14 and the second opening 15, respectively. The first opening 14 is used to allow external waste to enter the storage chamber 31, and the second opening 15 is used to adjust the air pressure in the storage chamber 31.

[0055] Specifically, both the first opening 14 and the second opening 15 communicate with the storage chamber 31. When the cleaning module is cleaning the surface to be cleaned and the storage element 30 is in the second state, the first opening 14 allows dirt scraped from the wiping element to enter the storage chamber 31, where the dirt entering the storage chamber 31 can be stably stored. When the dirt in the storage element 30 needs to be drained or cleaned, the first opening 14 can also be used to drain the dirt from the storage chamber 31 out of the storage element 30. In the height direction H of the sewage tank 10, the first opening 14 can be located at the bottom of the sewage tank 10. This allows the dirt in the storage chamber 31 to flow smoothly out of the storage element 30 due to gravity, resulting in less dirt remaining in the storage chamber 31. The cross-sectional shape of the first opening 14 can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0056] When the cleaning module is cleaning the surface to be cleaned and the storage element 30 is in the second state, dirt scraped off the wiping element by the scraping element needs to be stored in the storage chamber 31. In this case, the second opening 15 allows air in the storage chamber 31 to flow out. The air pressure in the storage chamber 31 is lower than the ambient air pressure, allowing dirt scraped off by the scraping element to flow into the storage chamber 31. When the storage element 30 switches from the second state to the first state and dirt in the storage chamber 31 needs to be discharged from the storage element 30, the second opening 15 allows air from the ambient air to enter the storage chamber 31. The air pressure in the storage chamber 31 is higher than the ambient air pressure, allowing dirt in the storage chamber 31 to flow out of the storage element 30 more quickly. The second opening 15 can be located at the top of the sewage tank 10 in the height direction H. This prevents dirt from clogging the second opening 15 when dirt is stored in the storage chamber 31, while also increasing the effective volume of the storage chamber 31.

[0057] Referring to Figures 1, 2, 3, and 5, further, in certain embodiments, the recovery assembly 100 further includes a first gas suction member 40. The first gas suction member 40 may be disposed on the cleaning module body 20 and connected to the second opening 15. When the storage element 30 is in the second state, the first gas suction member 40 is configured to extract gas from the storage chamber 31 through the second opening 15 to reduce the air pressure in the storage chamber 31, thereby allowing dirt to enter and / or remain in the storage chamber 31. The first gas suction member 40 may be any device capable of sucking gas, such as a fan or an air pump.

[0058] When the storage element 30 is in the second state, the volume of the storage chamber 31 is larger, allowing it to hold a larger amount of waste. While the first gas suction member 40 extracts gas from the storage chamber 31, reducing the pressure therein, the pressure remains greater than the pressure in the accommodating space 13. Consequently, the state of the storage element 30 remains unchanged while the first gas suction member 40 is extracting gas from the storage chamber 31. In other words, the storage element 30 remains stably in the second state, and the volume of the storage chamber 31 remains unchanged, allowing it to hold a larger amount of waste.

[0059] When the cleaning module cleans the surface to be cleaned and dirt from the wiping element is scraped off by the scraping element, the first gas suction element 40 is activated. As the first gas suction element 40 extracts gas from the storage chamber 31 through the second opening 15, a negative pressure is created within the storage chamber 31. The air pressure within the storage chamber 31 is lower than the ambient air pressure, causing dirt scraped off by the scraping element to flow into the storage chamber 31. After the dirt enters the storage chamber 31, if the first gas suction element 40 can remain airtight after deactivation, it can deactivate, maintaining a negative pressure within the storage chamber 31. This allows the dirt to be stably stored within the storage chamber 31, thereby preventing the dirt from flowing back from the storage chamber 31 to the surface to be cleaned. However, if the first gas suction element 40 cannot remain airtight after deactivation, it must continue to operate and must continue to pump the storage chamber 31. This allows the force generated by the negative pressure to counteract the gravity of the dirt entering the storage chamber 31, preventing it from flowing out of the first opening 14.

[0060] Please refer to Figures 1, 2, 3 and 5. In some embodiments, when the storage element 30 switches from the second state to the first state, the first gas suction element 40 is also used to pump air into the storage chamber 31 through the second opening 15 to increase the air pressure in the storage chamber 31 so that dirt can be quickly discharged from the storage chamber 31.

[0061] During the transition of the storage element 30 from the second state to the first state, the volume of the storage chamber 31 gradually decreases. In addition to being affected by gravity, waste stored in the storage chamber 31 is also squeezed by the storage element 30, causing it to rapidly flow out of the storage element 30. At this point, in some embodiments, the first gas suction element 40 switches from extracting gas from the storage chamber 31 to pumping air into the storage chamber 31. When the first gas suction element 40 pumps air into the storage chamber 31 through the second opening 15, the air pressure within the storage chamber 31 exceeds the ambient air pressure, thereby accelerating the discharge of waste from the storage chamber 31. In other embodiments, the air pressure within the accommodating space 13 can be increased, gradually increasing to a greater pressure than that within the storage chamber 31. This pressure can then squeeze the storage element 30, reducing its volume and allowing the storage element 30 to transition from the second state to the first state. At this point, nearly all of the waste in the storage chamber 31 is discharged, leaving less waste remaining. The number of second openings 15 can be, but is not limited to, one, two, three, or more. When the number of second openings 15 is one, the structure of the sewage tank 10 is relatively simple, and the processing of the sewage tank 10 is relatively simple. When the number of second openings 15 is multiple, the first gas suction member 40 is connected to multiple second openings 15. The first gas suction member 40 can simultaneously extract the gas in the storage chamber 31 through the multiple second openings 15. The first gas suction member 40 can quickly extract the gas in the storage chamber 31, and the first gas suction member 40 has a high efficiency in extracting the gas from the storage chamber 31. The first gas suction member 40 can also pump air into the storage chamber 31 simultaneously through multiple second openings 15, so that the dirt in the storage device can be quickly discharged to the outside of the storage member 30. The number of second openings 15 in the embodiment of the present application is one.

[0062] When the first gas suction member 40 is used to extract gas from the storage chamber 31 and also pumps gas into the storage chamber 31, the structure of the recovery assembly 100 is relatively simple, and the number of components in the recovery assembly 100 is relatively small, which can save costs. When the second opening 15 is used to allow gas from the storage chamber 31 to flow into the first gas suction member 40 and also allows gas in the first gas suction member 40 to enter the storage chamber 31, the structure of the sewage tank 10 is relatively simple, and the sewage tank 10 is relatively easy to manufacture.

[0063] Referring to Figures 1, 2, 3, and 5, in some embodiments, waste can be discharged from the storage chamber 31 through the first opening 14. In this case, the first opening 14 allows waste stored in the storage chamber 31 to be discharged outside the storage element 30. The first opening 14 also allows waste in the storage chamber 31 to be discharged outside the storage element 30 when external liquid is used to clean the storage element 30. This simplifies the structure of the wastewater tank 10 and makes it easier to manufacture.

[0064] In another embodiment, the sewage tank 10 further comprises a third opening, which communicates with the storage chamber 31. Dirt can be discharged from the storage chamber 31 through the third opening. During the transition of the storage element 30 from the second state to the first state, the third opening allows dirt in the storage chamber 31 to be discharged outside the storage element 30. The third opening also allows dirt in the storage chamber 31 to flow out of the storage element 30 when the storage element 30 is cleaned with an external liquid. Preferably, the third opening is located at the bottom of the sewage tank 10 in the height direction H. This allows dirt in the storage chamber 31 to flow smoothly out of the storage element 30 due to gravity, resulting in less dirt remaining in the storage chamber 31.

[0065] When the first opening 14 is used to allow waste to enter the storage element 30, and the third opening is used to discharge waste from the storage chamber 31 to the outside of the storage element 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage chamber 31 through the first opening 14, and waste in the storage chamber 31 can also quickly flow out through the third opening. Furthermore, if the first opening 14 malfunctions, the first opening 14 will not affect the function of the third opening. Therefore, the sewage tank 10 has good stability and reliability.

[0066] If the sewage tank 10 is provided with a third opening, the third opening is used to discharge waste from the storage chamber 31 to the exterior of the storage element 30. In this case, the first opening 14 can be used to allow air to enter the storage chamber 31. Preferably, in the height direction H of the sewage tank 10, the third opening can be located at the bottom of the sewage tank 10, and the first opening 14 can be located at the top of the sewage tank 10. When waste from the storage chamber 31 needs to be discharged, the first air suction element 40 can pump air into the storage chamber 31 through the second opening 15, thereby discharging waste from the storage chamber 31 out of the sewage tank 10 through the third opening. When the cleaning module is cleaning the surface to be cleaned, the third opening is closed. When waste from the storage chamber 31 needs to be discharged, the third opening is opened to allow the waste to flow out of the sewage tank 10. This prevents waste from the storage chamber 31 from flowing back onto the surface to be cleaned while the cleaning module is cleaning the surface.

[0067] Referring to Figures 1, 2, 3, and 5, further, in certain embodiments, the recovery assembly 100 further includes a second gas suction member, which is disposed on the body 20 and connected to the second opening 15. During the process of switching the storage element 30 from the second state to the first state, the second gas suction member is configured to pump air into the storage chamber 31 through the second opening 15, thereby increasing the air pressure in the storage chamber 31 and rapidly discharging the waste from the storage chamber 31. The second gas suction member can be any device capable of sucking gas, such as a fan or an air pump.

[0068] The second gas suction member is disposed within the main body 20 and spaced apart from the first gas suction member 40. As the storage member 30 switches from the second state to the first state, the volume of the storage chamber 31 gradually decreases. In addition to being affected by gravity, the dirt stored within the storage chamber 31 is squeezed by the storage member 30, causing it to rapidly flow out of the storage chamber 30. At this point, the second gas suction member is activated. When the second gas suction member pumps air into the storage chamber 31 through the second opening 15, the air pressure within the storage chamber 31 is greater than the external air pressure, thereby accelerating the discharge of dirt from the storage chamber 31. Nearly all of the dirt within the storage chamber 31 can be discharged from the storage member 30, leaving relatively little dirt.

[0069] When the first gas suction member 40 is used to extract gas from the storage chamber 31 and the second gas suction member is used to pump gas into the storage chamber 31, the second gas suction member can be quickly activated to pump gas into the storage chamber 31 when waste needs to be discharged from the storage chamber 31. The first gas suction member 40 does not need to switch from a vacuuming mode to a pumping mode. The use of the second gas suction member saves time during this switching process, allowing waste to be quickly discharged from the first opening 14 to the outside of the storage chamber 30. Furthermore, the first gas suction member 40 and the second gas suction member have clear divisions of labor, resulting in a longer service life for the first gas suction member 40 and the second gas suction member. In some embodiments, since the second gas suction member is used to pump gas into the storage chamber 31, the first gas suction member 40 can also be equipped with a pump that only has an extraction function to save costs.

[0070] In some embodiments, dirt can be discharged from the storage chamber 31 through the first opening 14. When the first opening 14 is used to allow dirt from the wiping member to enter the storage chamber 31 and is also used to allow dirt in the storage chamber 31 to be discharged outside the storage member 30, the structure of the dirty water tank 10 is relatively simple, and the manufacturing of the dirty water tank 10 is relatively simple.

[0071] In other embodiments, waste is discharged from the storage chamber 31 through the third opening. When the first opening 14 is used to allow waste to enter the storage element 30, and the third opening is used to allow waste in the storage chamber 31 to be discharged outside the storage element 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage chamber 31 through the first opening 14, and waste in the storage chamber 31 can also quickly flow out through the third opening. Furthermore, if the first opening 14 malfunctions, the first opening 14 will not affect the function of the third opening. This improves the stability and reliability of the sewage tank 10.

[0072] Referring to Figures 1, 2, 3, and 5, in certain embodiments, the storage chamber 31 is in communication with a liquid supply member 50. When the storage member 30 is in a first state, the liquid supply member 50 is configured to supply cleaning liquid into the storage chamber 31 to clean the storage chamber 31. The liquid supply member 50 may be disposed on the cleaning module body 20, on a cleaning device, on a cleaning base station, or from an external water source such as tap water.

[0073] In some embodiments, the liquid supply member 50 is connected to the second opening 15. When the storage member 30 is in the first state, the liquid supply member 50 is used to supply cleaning liquid into the storage chamber 31 through the second opening 15. The cleaning liquid here is the same as the "liquid" referred to above, and the cleaning liquid includes clean water or a cleaning liquid added with a cleaning solution.

[0074] When the storage element 30 switches from the second state to the first state, waste in the storage chamber 31 flows out of the storage element 30 through the first opening 14 or the third opening. When the storage element 30 is in the first state, most of the waste in the storage chamber 31 has already been discharged, but some waste may remain. If the storage element 30 needs to be cleaned, the liquid supply element 50 supplies cleaning liquid to the storage element 30. In this case, the second opening 15 also allows liquid to enter the storage chamber 31. When the second opening 15 is used to regulate the air pressure in the storage chamber 31 and also allows cleaning liquid to enter the storage chamber 31, the structure of the sewage tank 10 is relatively simple, and the sewage tank 10 is relatively easy to manufacture.

[0075] Referring to Figures 1, 2, 3, and 5, when the liquid supply member 50 supplies cleaning liquid into the storage chamber 31 through the second opening 15, the cleaning liquid, after entering the storage chamber 31, can carry away the dirt within the storage chamber 31 and flow out of the storage chamber 30. In this state, the storage chamber 30 is in a first state, with a smaller volume. The cleaning liquid entering the storage chamber 31 can flow through various locations on the inner sidewall of the storage chamber 30, thereby carrying away dirt from various locations on the inner sidewall of the storage chamber 30 and flowing out of the storage chamber 31, improving the cleaning effect of the storage chamber 30. If the second opening 15 is located at the top of the sewage tank 10, after the cleaning liquid enters the storage chamber 31 through the second opening 15, it will flow down the inner sidewall of the storage chamber 30 due to gravity, carrying away dirt from various locations on the inner sidewall of the storage chamber 30 and flowing out of the storage chamber 31, improving the cleaning effect of the storage chamber 30.

[0076] In one embodiment, the liquid supply member 50 may be a clean water tank of the cleaning module, connected to the second opening 15. When the storage element 30 is in the first state and needs to be cleaned, the clean water tank supplies cleaning liquid to the storage chamber 31 through the second opening 15. The liquid supply member 50 may also include a valve disposed between the clean water tank and the second opening 15. When the storage element 30 does not need to be cleaned, the valve is closed, preventing the cleaning liquid in the clean water tank from flowing into the storage chamber 31 through the second opening 15. When the storage element 30 needs to be cleaned and is in the first state, the valve is opened, allowing the cleaning liquid in the clean water tank to flow into the storage chamber 31 through the second opening 15 and clean the storage element 30.

[0077] In another embodiment, the liquid supply member 50 may be an external water source connected to the second opening 15. When the storage member 30 is in the first state and needs to be cleaned, the external water source supplies cleaning liquid into the storage chamber 31 through the second opening 15. The liquid supply member 50 may also include a valve disposed between the external water source and the second opening 15. When the storage member 30 does not need to be cleaned, the valve is closed, preventing the cleaning liquid from the external water source from flowing into the storage chamber 31 through the second opening 15. When the storage member 30 needs to be cleaned and is in the first state, the valve is opened, allowing the cleaning liquid from the external water source to flow into the storage chamber 31 through the second opening 15 and clean the storage member 30.

[0078] In some embodiments, when cleaning liquid enters the storage chamber 31 and cleans the storage chamber 31, the first opening 14 is used to allow dirt in the storage chamber 31 to flow out of the storage element 30. When the first opening 14 is used to allow dirt from the mopping member to enter the storage chamber 31 and is also used to allow dirt in the storage chamber 31 to be discharged out of the storage element 30, the structure of the sewage tank 10 is relatively simple, and the sewage tank 10 is relatively easy to manufacture.

[0079] In other embodiments, when cleaning liquid enters and cleans the storage chamber 31, the third opening is used to allow waste in the storage chamber 31 to flow out of the storage element 30. When the first opening 14 is used to allow waste to enter the storage element 30, and the third opening is used to allow waste in the storage chamber 31 to flow out of the storage element 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage chamber 31 through the first opening 14, and waste in the storage chamber 31 can also quickly flow out of the third opening. Furthermore, if the first opening 14 malfunctions, the first opening 14 will not affect the function of the third opening. This also improves the stability and reliability of the sewage tank 10.

[0080] Referring to Figures 1, 2, 3 and 5, in some embodiments, the sewage tank 10 is further provided with a fourth opening 17, which is communicated with the storage chamber 31; a liquid supply member 50 is connected to the fourth opening 17. When the storage member 30 is in the first state, the liquid supply member 50 is used to supply cleaning liquid to the storage chamber 31 through the fourth opening 17.

[0081] During the transition of the storage element 30 from the second state to the first state, waste in the storage chamber 31 flows out of the storage element 30 through the first opening 14 or the third opening. When the storage element 30 is in the first state, most of the waste in the storage chamber 31 has already been discharged. Some waste may remain in the storage element 30. If the storage element 30 needs to be cleaned, the liquid supply element 50 provides cleaning liquid to the storage element 30. During this time, the fourth opening 17 is used to allow liquid to enter the storage chamber 31. Since the second opening 15 is used to regulate the air pressure in the storage chamber 31 and the fourth opening 17 is used to allow cleaning liquid to enter the storage chamber 31, the second opening 15 and the fourth opening 17 do not interfere with each other. If the second opening 15 malfunctions, the second opening 15 will not affect the function of the fourth opening 17. If the fourth opening 17 malfunctions, the fourth opening 17 will not affect the function of the second opening 15, resulting in excellent stability and reliability of the sewage tank 10.

[0082] When the liquid supply element 50 supplies cleaning liquid into the storage chamber 31 through the fourth opening 17, the cleaning liquid, after entering the storage chamber 31, can carry away the dirt within the storage chamber 31 and flow out of the storage chamber 30. At this time, the storage chamber 30 is in the first state, with the volume of the storage chamber 31 being relatively small. The cleaning liquid entering the storage chamber 31 can flow through various locations on the inner sidewall of the storage chamber 30, thereby carrying away dirt from various locations on the inner sidewall of the storage chamber 30 and flowing out of the storage chamber 31, thus achieving a better cleaning effect. If the fourth opening 17 is located at the top of the dirty water tank 10, after the cleaning liquid enters the storage chamber 31 through the fourth opening 17, it will flow down the inner sidewall of the storage chamber 30 due to gravity, carrying away dirt from various locations on the inner sidewall of the storage chamber 30 and flowing out of the storage chamber 31, thus achieving a better cleaning effect.

[0083] In some embodiments, when cleaning liquid enters the storage chamber 31 and cleans the storage chamber 31, the first opening 14 is used to allow dirt in the storage chamber 31 to flow out of the storage element 30. When the first opening 14 is used to allow dirt from the mopping member to enter the storage chamber 31 and is also used to allow dirt in the storage chamber 31 to be discharged out of the storage element 30, the structure of the sewage tank 10 is relatively simple, and the sewage tank 10 is relatively easy to manufacture.

[0084] In other embodiments, when cleaning liquid enters and cleans the storage chamber 31, the third opening is used to allow waste in the storage chamber 31 to flow out of the storage element 30. When the first opening 14 is used to allow waste to enter the storage element 30, and the third opening is used to allow waste in the storage chamber 31 to flow out of the storage element 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage chamber 31 through the first opening 14, and waste in the storage chamber 31 can also quickly flow out of the third opening. Furthermore, if the first opening 14 malfunctions, the first opening 14 will not affect the function of the third opening. This also improves the stability and reliability of the sewage tank 10.

[0085] Please refer to Figures 1, 2, 3 and 5. In some embodiments, the sewage tank 10 is further provided with a fifth opening 18. The fifth opening 18 is communicated with the accommodating space 13. The fifth opening 18 is used to adjust the air pressure in the accommodating space 13.

[0086] Referring to Figures 1, 2, 3, and 5, in certain embodiments, the recovery assembly 100 further includes a third gas suction member 60. The third gas suction member 60 is disposed on the body 20 and connected to the fifth opening 18. The third gas suction member 60 is configured to extract gas from the accommodating space 13 through the fifth opening 18, thereby reducing the air pressure in the accommodating space 13 and switching the storage element 30 from the first state to the second state. The third gas suction member 60 can be any device capable of sucking gas, such as a fan or an air pump.

[0087] Specifically, when the cleaning module is cleaning the surface to be cleaned, the storage element 30 needs to store dirt from the mopping element. At this point, the storage element 30 needs to be in the second state, increasing the volume of the storage chamber 31 and allowing it to hold more dirt. When the storage element 30 needs to switch from the first state to the second state, the third gas suction element 60 is activated, and the fifth opening 18 allows the third gas suction element 60 to extract gas from the storage space 13. When the air pressure in the storage space 13 is lower than the air pressure in the storage chamber 31, the elastic storage element 30 expands, allowing the storage element 30 to switch from the first state to the second state. During the process of loading the storage chamber 31 with dirt, or in order to ensure that the storage element 30 is stable in the second state, the third gas suction element 60 that can remain sealed after stopping work can stop working when the storage element 30 reaches the second state; while the third gas suction element 60 that cannot remain sealed after stopping work needs to continue working to keep the storage element 30 stable in the second state, so as to prevent the elastic storage element 30 from deforming back to the first state and causing the dirt in the storage chamber 31 to flow out.

[0088] When the first gas suction member 40 extracts gas from the storage chamber 31 through the second opening 15, the third gas suction member 60 also works at the same time, so that the air pressure in the accommodating space 13 is always lower than the air pressure in the storage chamber 31. The storage member 30 can be maintained in the second state, and the storage chamber 31 can be loaded with more dirt.

[0089] 1 , 2 , 3 and 5 , in some embodiments, the third gas suction member 60 is further configured to pump gas into the accommodating space 13 through the fifth opening 18 to increase the gas pressure in the accommodating space 13 , so as to switch the storage member 30 from the second state to the first state.

[0090] When waste in the storage element 30 needs to be discharged from the storage chamber 31, the third gas suction member 60 switches from extracting gas from the accommodating space 13 to pumping gas into the accommodating space 13. The fifth opening 18 also allows gas in the third gas suction member 60 to enter the accommodating space 13. When the fifth opening 18 allows gas in the accommodating space 13 to flow into the third gas suction member 60 and also allows gas in the third gas suction member 60 to enter the accommodating space 13, the structure of the wastewater tank 10 is relatively simple, and the manufacture of the wastewater tank 10 is relatively simple.

[0091] When the storage element 30 needs to switch from the second state to the first state, the third gas suction member 60 is activated and pumps air into the storage space 13 through the fifth opening 18. When the air pressure in the storage space 13 exceeds the air pressure within the storage chamber 31, the elastic storage element 30 is compressed, allowing the storage element 30 to switch from the second state to the first state. When the third gas suction member 60 switches the storage element 30 from the second state to the first state, the first gas suction member 40 or the second gas suction member can simultaneously pump air into the storage chamber 31, thereby accelerating the discharge of dirt from the storage chamber 31. After the storage element 30 switches from the second state to the first state, the volume of the storage chamber 31 decreases, facilitating cleaning of the storage element 30.

[0092] When the third gas suction member 60 is used to extract gas from the accommodating space 13 and is also used to pump gas into the accommodating space 13, the structure of the recovery component 100 is relatively simple, and the recovery component 100 has fewer components, which can save costs.

[0093] Referring to Figures 1, 2, 3, and 5, in certain embodiments, the recovery assembly 100 further includes a fourth gas suction member disposed on the body 20 and connected to the fifth opening 18. The fourth gas suction member is configured to pump air into the accommodating space 13 through the fifth opening 18, thereby increasing the air pressure in the accommodating space 13 and switching the storage element 30 from the second state to the first state. The fourth gas suction member 40 can be any device capable of sucking gas, such as a fan or an air pump.

[0094] When dirt in the storage element 30 needs to be discharged from the storage chamber 31, the fourth gas suction member is used to pump air into the storage space 13. The fifth opening 18 is also used to allow gas in the fourth gas suction member to enter the storage space 13. When the storage element 30 needs to switch from the second state to the first state, the fourth gas suction member is activated and pumps air into the storage space 13 through the fifth opening 18. When the air pressure in the storage space 13 exceeds the air pressure in the storage chamber 31, the elastic storage element 30 is compressed, allowing the storage element 30 to switch from the second state to the first state. When the fourth gas suction member causes the storage element 30 to switch from the second state to the first state, the first gas suction member 40 or the second gas suction member can pump air into the storage chamber 31 individually or simultaneously, thereby accelerating the discharge of dirt from the storage chamber 31. After the storage element 30 switches from the second state to the first state, the volume of the storage chamber 31 decreases, which not only facilitates the discharge of dirt but also facilitates the cleaning of the storage element 30.

[0095] When the third gas suction member 60 is used to extract gas from the storage space 13, and the fourth gas suction member is used to pump gas into the storage space 13, when the storage element 30 needs to switch from the second state to the first state, the fourth gas suction member can be quickly activated to pump gas into the storage space 13. The third gas suction member 60 does not need to switch from the extraction state to the pumping state. The use of the fourth gas suction member saves time during this switching process, allowing the storage element 30 to quickly switch from the second state to the first state. Furthermore, the clear division of labor between the third and fourth gas suction members 60 and 60 ensures a long service life.

[0096] Referring to Figures 1, 2, 3, and 5, in certain embodiments, the sewage tank 10 further comprises a sixth opening, which communicates with the storage space 13. The third gas suction member 60 extracts gas from the storage space 13 through the fifth opening 18, thereby reducing the air pressure therein and switching the storage element 30 from the first state to the second state. The fourth gas suction member pumps air into the storage space 13 through the sixth opening, thereby increasing the air pressure therein and switching the storage element 30 from the second state to the first state.

[0097] When dirt in the storage element 30 needs to be discharged from the storage chamber 31, the fourth gas suction member is used to pump air into the storage space 13. The sixth opening is used to allow gas in the fourth gas suction member to enter the storage space 13. When the storage element 30 needs to switch from the second state to the first state, the fourth gas suction member is activated and pumps air into the storage space 13 through the sixth opening. When the air pressure in the storage space 13 is greater than or equal to the air pressure in the storage chamber 31, the elastic storage element 30 is compressed, allowing the storage element 30 to switch from the second state to the first state. When the fourth gas suction member causes the storage element 30 to switch from the second state to the first state, the first gas suction member 40 or the second gas suction member can pump air into the storage chamber 31 individually or simultaneously, thereby accelerating the discharge of dirt from the storage chamber 31. After the storage element 30 switches from the second state to the first state, the volume of the storage chamber 31 decreases, facilitating both the discharge of dirt and the cleaning of the storage element 30.

[0098] When the second opening 15 is used to regulate the air pressure in the storage chamber 31 and the fourth opening 17 is used to allow cleaning liquid to enter the storage chamber 31, the second opening 15 and the fourth opening 17 do not interfere with each other. If the second opening 15 fails, the second opening 15 will not affect the function of the fourth opening 17. If the fourth opening 17 fails, the fourth opening 17 will not affect the function of the second opening 15, thereby improving the stability and reliability of the sewage tank 10.

[0099] Referring to Figures 1 and 2 , in certain embodiments, the recovery assembly 100 further includes a sewage trough 70, a sewage discharge member 80, and a connecting pipe 90. The sewage trough 70 may be disposed within the cleaning module body 20 and is configured to receive waste. The sewage discharge member 80 may be disposed within the cleaning module body 20 and may include a sewage outlet 81. The sewage discharge member 80 communicates with the sewage trough 70 and, when the storage member 30 switches from the second state to the first state, the sewage outlet 81 allows waste within the sewage trough 70 to be discharged. The connecting pipe 90 has one end connected to the storage member 30 and the other end connected to the sewage trough 70.

[0100] Specifically, the connecting pipe 90 is connected to the first opening 14 of the sewage tank 10, or the connecting pipe 90 is connected to both the first opening 14 and the third opening of the sewage tank 10. The connecting pipe 90 is used to connect the sewage tank 70 and the storage chamber 31. The sewage in the sewage tank 70 can enter the storage chamber 31 through the connecting pipe 90, and the sewage in the storage chamber 31 can also enter the sewage tank 70 through the connecting pipe 90.

[0101] In one embodiment, the connecting pipe 90 is connected to the first opening 14. When the cleaning module is cleaning the surface to be cleaned, dirt from the wiping member enters the sewage trough 70, flows from the sewage trough 70 into the connecting pipe 90, and enters the storage chamber 31 through the first opening 14. When the dirt in the storage chamber 31 needs to be drained, the dirt in the storage chamber 31 flows from the first opening 14 into the connecting pipe 90, passes through the sewage trough 70, and is discharged from the drainage member 80. In another embodiment, the connecting pipe 90 is connected to both the first opening 14 and the third opening. When the cleaning module is cleaning the surface to be cleaned, dirt from the wiping member enters the sewage trough 70, flows from the sewage trough 70 into the connecting pipe 90, and enters the storage chamber 31 through the first opening 14. When the dirt in the storage chamber 31 needs to be drained, the third opening is open, and the dirt in the storage chamber 31 can flow out of the sewage tank 10 through the third opening.

[0102] The material of the connecting pipe 90 may be, but is not limited to, metal, plastic, rubber, etc. When the material of the connecting pipe 90 is metal, the connecting pipe 90 has a higher strength, better wear resistance, and a longer service life. When the material of the connecting pipe 90 is plastic, the connecting pipe 90 is lighter and has a lower cost. When the material of the connecting pipe 90 is rubber, the connecting pipe 90 is more flexible and has a longer service life. The sewage discharge part 80 is used to discharge the sewage in the sewage tank 70 to the outside of the recovery component 100. The material of the sewage discharge part 80 may be, but is not limited to, metal, plastic, etc. When the material of the sewage discharge part 80 is metal, the sewage discharge part 80 has a higher strength, better wear resistance, and a longer service life. When the material of the sewage discharge part 80 is plastic, the sewage discharge part 80 is lighter and has a lower cost.

[0103] The storage chamber 31, connecting pipe 90, sewage trough 70, and waste discharge member 80 are sequentially connected. When the cleaning module cleans the surface to be cleaned, dirt from the wiping member is scraped off by the scraping member and falls into the sewage trough 70. The third gas suction member 60 is activated and extracts gas from the storage space 13 through the fifth opening 18. The air pressure in the storage chamber 31 becomes greater than the air pressure in the storage space 13, causing the storage member 30 to expand and switch from the first state to the second state. The volume of the storage chamber 31 increases, allowing it to store waste entering the sewage trough 70. The first gas suction member 40 is also activated and extracts gas from the storage chamber 31 through the second opening 15, creating a negative pressure in the storage chamber 31. As a result, waste from the sewage trough 70 flows into the connecting pipe 90 and then into the storage chamber 31 through the first opening 14, where it can be stored. When the dirt in the storage chamber 31 (here, the dirt stored in the mopping member in the storage chamber 31) needs to be discharged, the third gas suction member 60 or the fourth gas suction member pumps air into the storage space 13 through the fifth opening 18, or the fourth gas suction member pumps air into the storage space 13 through the sixth opening. The air pressure in the storage chamber 31 becomes lower than the air pressure in the storage space 13, causing the storage member 30 to contract, switching from the second state to the first state. Furthermore, the first gas suction member 40 or the second gas suction member pumps air into the storage chamber 31 through the second opening 15. The air pressure in the storage chamber 31 is higher than the external air pressure, and the dirt in the storage chamber 31 passes through the connecting pipe 90 and the sewage tank 70 and is discharged from the sewage outlet 81.

[0104] During the cleaning process, the storage element 30 is in a first state. In this state, the storage element 30 is a tubular structure, and the storage chamber 31 has a relatively small volume. Liquid enters the storage chamber 31, flows through various locations on the inner sidewall of the storage element 30, and carries dirt from the storage chamber 31 out through the first opening 14 or the third opening. As the liquid flows through the connecting pipe 90, the sewage trough 70, and the sewage discharge member 80, it flushes these areas, keeping them relatively clean.

[0105] Please refer to FIG. 7 . In a third aspect, an embodiment of the present application provides a cleaning device 1000 . The cleaning device 1000 includes a body 300 and the recovery component 100 of the above embodiment. The recovery component 100 is disposed on the body 300 .

[0106] Please refer to FIG. 7 . In a fourth aspect, an embodiment of the present application provides a cleaning device 1000 . The cleaning device 1000 includes a body 300 and the cleaning module of the above embodiment. The cleaning module is disposed on the body 300 .

[0107] In conjunction with Figures 3 and 5 , in one embodiment, the cleaning device 1000 may include a liquid supply unit. The liquid supply unit may be located on the body 300 and connected to the second opening 15 or the fourth opening 17. When the storage unit 30 needs to be cleaned and is in the first state, the liquid supply unit is configured to supply cleaning liquid to the storage chamber 31 through the second opening 15 or the fourth opening 17. The liquid supply unit may include a clean water tank of the cleaning device 1000. When the storage unit 30 is in the first state, the clean water tank of the cleaning device 1000 supplies cleaning liquid to the storage unit 30. The liquid supply unit may also include a valve located between the clean water tank of the cleaning device 1000 and the second opening 15 or the fourth opening 17. When the storage unit 30 does not need to be cleaned, the valve is closed, preventing the cleaning liquid in the clean water tank of the cleaning device 1000 from flowing into the storage chamber 31 through the second opening 15 or the fourth opening 17. When the storage element 30 needs to be cleaned and is in the first state, the valve is opened, and the cleaning liquid in the clean water tank of the cleaning device 1000 can flow into the storage chamber 31 through the second opening 15 or the fourth opening 17 .

[0108] In the cleaning device 1000 according to the embodiment of the present application, the storage element 30 can switch between a first state and a second state. When the storage element 30 is in the first state, the volume of the storage chamber 31 is smaller than when the storage element 30 is in the second state. When the storage element 30 needs to store dirt, the storage element 30 can be in the second state. When the storage element 30 needs to be cleaned, the storage element 30 can be switched to the first state. Because the volume of the storage chamber 31 is smaller when the storage element 30 is in the first state, liquid entering the storage chamber 31 can more easily reach various locations within the storage chamber when cleaning the storage chamber 31, thereby improving cleaning efficiency within the storage chamber and reducing blind spots. This makes cleaning the storage element 30 easier and provides a better cleaning effect.

[0109] Please refer to FIG8 . In a fifth aspect, an embodiment of the present application further provides a cleaning system 10000 . The cleaning system 10000 includes a base station 3000 and the cleaning device 1000 of the above embodiment.

[0110] Among them, the base station 3000 is a device used to maintain, service, and charge the cleaning device 1000. For example, the base station 3000 can clean the mopping part of the cleaning device 1000, and the base station 3000 can also charge the cleaning device 1000. Furthermore, the base station 3000 can also have at least one of the following functions: replenishing water, draining water, collecting dust, etc. for the cleaning device 1000. When the mopping part of the cleaning device 1000 is dirty and / or low on power, the cleaning device 1000 returns to the base station 3000 to clean the mopping part and / or charge. When the mopping part of the cleaning device 1000 is cleaned and / or fully charged, the cleaning device 1000 can leave the base station 3000 and continue cleaning the surface to be cleaned.

[0111] Referring to Figures 3 and 5 , in one embodiment, the cleaning system 10000 may include a liquid supply component. The liquid supply component may be located at the base station 3000. When the cleaning device 1000 enters the base station 3000, the liquid supply component connects to the second opening 15 or the fourth opening 17. When the storage element 30 needs to be cleaned and the storage element 30 is in the first state, the cleaning device 1000 enters the base station 3000, and the liquid supply component supplies cleaning liquid to the storage chamber 31 through the second opening 15 or the fourth opening 17. The liquid supply component may include a clean water tank of the cleaning system 10000. When the storage element 30 is in the first state, the clean water tank of the cleaning system 10000 supplies cleaning liquid to the storage element 30. The liquid supply component may also include a valve located between the clean water tank of the cleaning system 10000 and the second opening 15 or the fourth opening 17. When the storage element 30 does not need to be cleaned, the valve is closed, so that the cleaning liquid in the clean water tank of the cleaning system 10000 does not flow into the storage chamber 31 through the second opening 15 or the fourth opening 17. When the storage element 30 needs to be cleaned and the storage element 30 is in the first state, the valve is opened, and the cleaning liquid in the clean water tank of the cleaning system 10000 can flow into the storage chamber 31 through the second opening 15 or the fourth opening 17.

[0112] In the cleaning system 10000 according to the embodiment of the present application, the storage element 30 can switch between a first state and a second state. When the storage element 30 is in the first state, the volume of the storage chamber 31 is smaller than when the storage element 30 is in the second state. When the storage element 30 needs to store dirt, the storage element 30 can be in the second state. When the storage element 30 needs to be cleaned, the storage element 30 can be switched to the first state. Because the volume of the storage chamber 31 is smaller when the storage element 30 is in the first state, liquid entering the storage chamber 31 can more easily reach various locations within the storage chamber during cleaning. This improves cleaning efficiency within the storage chamber and reduces blind spots. This simplifies cleaning of the storage element 30 and provides a more effective cleaning effect.

[0113] Referring to FIG. 1 , FIG. 2 , and FIG. 9 , in a fourth aspect, embodiments of the present application further provide a cleaning method, which is applied to the recycling assembly 100 , cleaning module, cleaning device 1000 , and cleaning system 10000 of the above embodiments. The cleaning method includes:

[0114] 01: extracting waste into the storage chamber 31;

[0115] 03: discharge the waste out of the storage chamber 31; and

[0116] 05: Clean the storage chamber 31.

[0117] Specifically, when the cleaning module cleans the surface to be cleaned, the scraping member scrapes away dirt from the wiping member, and the dirt enters the sewage tank 70. The controller of the recovery assembly 100 can control the first gas suction member 40 to activate, so that the dirt in the sewage tank 70 is sucked into the storage member 30. The dirt passes through the connecting pipe 90 and enters the storage chamber 31 from the first outlet, where it is stored.

[0118] When the storage chamber 31 is filled with dirt or the cleaning robot has finished cleaning the surface to be cleaned, the cleaning robot enters the base station 3000 or moves to a designated waste discharge location. The controller controls the waste in the storage chamber 31 to be discharged outside the storage element 30. The waste in the storage chamber 31 flows out of the storage chamber 31 through the first outlet or the third outlet, passes through the connecting pipe 90 and the waste tank 70, and is discharged from the waste outlet 81.

[0119] When waste is discharged from the storage chamber 31, the controller activates the liquid supply member 50, allowing external liquid to enter the storage chamber 31 to flush the storage chamber 31. The liquid flows through various locations on the inner wall of the storage member 30, carrying waste on the inner wall of the storage member 30 and out of the storage chamber 31 through the first outlet or the third outlet. The waste then passes through the connecting pipe 90 and the waste tank 70 and is discharged from the waste outlet 81.

[0120] Referring to FIG. 3 , FIG. 4 and FIG. 10 , in certain embodiments, 01: extracting waste into the storage chamber 31 includes:

[0121] 011: Extracting gas from the accommodating space 13 and reducing the air pressure in the accommodating space 13 so that the storage element 30 switches from the first state to the second state; and 013: Extracting gas from the storage chamber 31 and reducing the air pressure in the storage chamber 31 so that dirt enters and remains in the storage chamber 31.

[0122] Specifically, the controller activates the third gas suction member 60, which extracts gas from the storage space 13 through the fifth outlet, reducing the pressure in the storage space 13 to a value lower than the pressure in the storage chamber 31. This causes the elastic storage member 30 to expand, switching from the first state to the second state. In the second state, the storage chamber 31 has a larger volume and is used to store waste.

[0123] After the storage element 30 switches from the first state to the second state, the third gas suction element 60 continues to operate, and the controller activates the first gas suction element 40. The first gas suction element 40 extracts gas from the storage chamber 31 through the second opening 15, causing the air pressure within the storage chamber 31 to be lower than the ambient air pressure, but higher than the current air pressure in the storage space 13. This allows the storage element 30 to remain stably in the second state, and dirt in the sump 70 can be squeezed into the storage chamber 31. The first gas suction element 40 continues to operate to ensure that dirt is stored in the storage chamber 31, preventing it from flowing from the storage chamber 31 to the surface to be cleaned.

[0124] Please refer to FIG. 3 , FIG. 4 , and FIG. 11 to FIG. 13 . In certain embodiments, 03: discharging waste out of the storage chamber 31 includes:

[0125] 031: Pumping air into the accommodating space 13 to increase the air pressure in the accommodating space 13 so that dirt is discharged from the storage chamber 31; and / or 033: Pumping air into the storage chamber 31 to increase the air pressure in the storage chamber 31 so that dirt is discharged from the storage chamber 31.

[0126] Specifically, referring to Figures 3, 4, and 11, in one embodiment, when waste needs to be discharged from the storage chamber 31 to the exterior of the storage element 30, air is pumped into the accommodating space 13 to increase the air pressure therein, thereby discharging the waste from the storage chamber 31. In one example, the controller controls the third air suction member 60 to pump air into the accommodating space 13 through the fifth opening 18, thereby increasing the air pressure therein to be greater than that in the storage chamber 31. This compresses the elastic storage element 30, causing it to shrink, switching from the second state to the first state. During the transition from the second state to the first state, the volume of the storage chamber 31 gradually decreases, allowing waste in the storage chamber 31 to be discharged from the storage element 30 through the first opening 14 or the third opening. In another example, the controller controls the fourth air suction member 60 to pump air into the accommodating space 13 through the fifth opening 18, thereby increasing the air pressure therein to be greater than that in the storage chamber 31. The storage element 30 switches from the second state to the first state, the volume of the storage chamber 31 gradually decreases, and the dirt in the storage chamber 31 is discharged from the storage element 30 through the first opening 14 or the third opening. In another example, the controller controls the fourth gas suction element to pump air into the accommodating space 13 through the sixth opening, so that the air pressure in the accommodating space 13 is greater than the air pressure in the storage chamber 31. The storage element 30 switches from the second state to the first state, the volume of the storage chamber 31 gradually decreases, and the dirt in the storage chamber 31 is discharged from the storage element 30 through the first opening 14 or the third opening.

[0127] At this time, the controller only needs to activate the third gas suction member 60 or the fourth gas suction member to operate, which simplifies the controller's operation. In addition, the recycling assembly 100 has fewer components working simultaneously, and the recycling assembly 100 consumes less power.

[0128] Referring to Figures 3, 4, and 12, in another embodiment, when waste needs to be discharged from the storage chamber 31 to the exterior of the storage element 30, air is pumped into the storage chamber 31 to increase the air pressure therein, thereby discharging the waste from the storage chamber 31. In one example, the controller of the recovery assembly 100 controls the first gas suction member 40 to pump air into the storage chamber 31 through the second opening 15, thereby increasing the air pressure therein to be greater than the external air pressure. At this point, the storage element 30 remains in the second state. If the air pressure within the storage chamber 31 is greater than the external air pressure, the waste in the storage chamber 31 will be discharged from the storage element 30 through the first opening 14 or the third opening. In another example, the controller of the recovery assembly 100 controls the second gas suction member 40 to pump air into the storage chamber 31 through the second opening 15, thereby increasing the air pressure therein to be greater than the external air pressure. At this point, the storage element 30 remains in the second state. When the air pressure in the storage chamber 31 is greater than the external air pressure, the dirt in the storage chamber 31 will be discharged to the outside of the storage element 30 through the first opening 14 or the third opening.

[0129] At this point, the dirt in the storage chamber 31 can be almost completely discharged from the storage chamber 31, and less dirt remains in the storage chamber 31. Furthermore, the controller of the recovery assembly 100 only needs to activate the first gas suction member 40 or the second gas suction member to operate, making the controller's operation relatively simple. The recovery assembly 100 has fewer components operating simultaneously, and thus consumes less power.

[0130] Referring to Figures 3, 4, and 13, in another embodiment, when waste needs to be discharged from the storage chamber 31 to the outside of the storage element 30, air is pumped into the accommodating space 13 to increase the air pressure therein, and air is simultaneously pumped into the storage chamber 31 to increase the air pressure therein, thereby discharging waste from the storage chamber 31. In one example, the controller controls the simultaneous activation of the first and third air suction members 40 and 60. When the storage element 30 switches from the second state to the first state under the action of the third air suction member 60, the first air suction member 40 pumps air into the storage chamber 31, thereby rapidly discharging waste from the storage element 30. In another example, the controller controls the simultaneous activation of the first and fourth air suction members 40 and 40. When the storage element 30 switches from the second state to the first state under the action of the fourth air suction member, the first air suction member 40 pumps air into the storage chamber 31, thereby rapidly discharging waste from the storage element 30. In another example, the controller controls the simultaneous activation of the second and third gas suction members 60. When the storage element 30 switches from the second state to the first state under the action of the third gas suction member 60, the second gas suction member pumps air into the storage chamber 31, thereby quickly discharging waste from the storage chamber 31 out of the storage element 30. In another example, the controller controls the simultaneous activation of the second and fourth gas suction members. When the storage element 30 switches from the second state to the first state under the action of the fourth gas suction member, the second gas suction member pumps air into the storage chamber 31, thereby quickly discharging waste from the storage chamber 31 out of the storage element 30.

[0131] At this time, when the air pump corresponding to the storage chamber 31 and the air pump corresponding to the accommodating space 13 operate simultaneously, the dirt in the storage chamber 31 can be quickly discharged outside the storage element 30, and the efficiency of draining the dirt from the storage chamber 31 is high. In addition, the dirt in the storage chamber 31 can be almost completely drained from the storage chamber 31, and less dirt remains in the storage chamber 31.

[0132] Please refer to FIG3 , FIG4 and FIG14 , in some embodiments, 05: cleaning the storage chamber 31 includes:

[0133] 051: When dirt is discharged from the storage chamber 31 , cleaning liquid is supplied to the storage chamber 31 to clean the storage chamber 31 .

[0134] When dirt is discharged from the storage chamber 31 and the storage element 30 is in the first state, the controller controls the liquid supply part to provide cleaning liquid to the storage element 30 , and the cleaning liquid enters the storage chamber 31 and cleans the storage chamber 31 .

[0135] In one embodiment, the liquid supply unit may be equipped with a water pump. When the storage element 30 needs to be cleaned, the controller activates the water pump, allowing the cleaning liquid in the liquid supply unit to flow into the storage chamber 31. The cleaning liquid flows into various locations on the inner sidewall of the storage element 30, carrying dirt from the inner sidewall with it and flowing out of the storage element 30, thereby effectively cleaning the storage element 30. In one example, the liquid supply unit is connected to the second opening 15. When the controller activates the water pump, the cleaning liquid enters the storage chamber 31 through the second opening 15 and cleans the storage chamber 31. In another example, the liquid supply unit is connected to the fourth opening 17. When the controller activates the water pump, the cleaning liquid enters the storage chamber 31 through the fourth opening 17 and cleans the storage chamber 31.

[0136] In another embodiment, the liquid supply unit may include a valve. When the storage element 30 needs to be cleaned, the controller controls the valve to open, allowing cleaning liquid in the liquid supply unit to flow into the storage chamber 31. The cleaning liquid flows into various locations on the inner wall of the storage element 30, carrying dirt from the inner wall of the storage element 30 and flowing out of the storage element 30, thereby effectively cleaning the storage element 30. In one example, the liquid supply unit is connected to the second opening 15. When the controller controls the valve to open, the cleaning liquid enters the storage chamber 31 through the second opening 15 and cleans the storage chamber 31. In another example, the liquid supply unit is connected to the fourth opening 17. When the controller controls the valve to open, the cleaning liquid enters the storage chamber 31 through the fourth opening 17 and cleans the storage chamber 31.

[0137] In the cleaning method according to the embodiment of the present application, the storage element 30 can switch between a first state and a second state. When the storage element 30 is in the first state, the volume of the storage chamber 31 is smaller than when the storage element 30 is in the second state. When the storage element 30 needs to store dirt, the storage element 30 can be in the second state. When the storage element 30 needs to be cleaned, the storage element 30 can be switched to the first state. Because the volume of the storage chamber 31 is smaller when the storage element 30 is in the first state, liquid entering the storage chamber 31 can more easily reach various locations within the storage chamber during cleaning, thereby improving cleaning efficiency within the storage chamber and reducing blind spots. This makes cleaning the storage element 30 simpler and provides a more effective cleaning effect.
