Description

Technical Field

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

[0002] After cleaning the surface, the mop in the cleaning module will have wastewater on it. Continuing to clean the surface with this wastewater will result in poor cleaning effectiveness. Therefore, the cleaning robot can be equipped with a wastewater tank to collect and recycle the wastewater from the mop, thereby improving the cleaning effect. Currently, wastewater tanks typically have a self-cleaning function, meaning they automatically clean themselves when wastewater is discharged. However, the self-cleaning function of current wastewater tanks is not very effective. Utility Model Content

[0021] In some embodiments, the storage element is an elastomer.

[0022] In some embodiments, when the storage device is in the first state, the storage device is tubular in shape; and / or, when the storage device is in the second state, the shape of the storage device matches the shape of the receiving cavity.

[0026] Secondly, the cleaning module of the embodiments of this application includes a body, a mopping component, and a recycling component as described in any of the above embodiments, wherein the mopping component and the recycling component are both disposed on the body.

[0027] Thirdly, the cleaning equipment of the embodiments of this application includes a body and a recycling component as described in any of the above embodiments, wherein the recycling component is disposed on the body.

[0028] Fourthly, the cleaning equipment of the embodiments of this application includes a body and a cleaning module as described in any of the above embodiments, wherein the cleaning module is installed on the body.

[0029] In some embodiments, the cleaning equipment includes a tracked cleaning robot or a roller cleaning robot.

[0030] Fifthly, the cleaning system of the embodiments of this application includes a base station and the cleaning equipment described in any of the above embodiments.

[0031] Sixthly, the cleaning method of the embodiments of this application is applied to the recycling component described in any of the above embodiments, or to the cleaning module described in any of the above embodiments, or to the cleaning equipment described in the above embodiments, or to the cleaning system described in the above embodiments. The cleaning method includes: extracting dirt into the storage cavity; discharging the dirt out of the storage cavity; and cleaning the storage cavity.

[0032] In some embodiments, the step of extracting contaminants into the storage cavity includes: extracting gas from the containment space to reduce the gas pressure in the containment space, thereby switching the storage device from the first state to the second state; and extracting gas from the storage cavity to reduce the gas pressure in the storage cavity, thereby allowing the contaminants to enter and remain in the storage cavity.

[0033] In some embodiments, the discharge of the contaminant outside the storage cavity includes: pumping air into the receiving space to increase the air pressure in the receiving space, so as to discharge the contaminant from the storage cavity; and / or pumping air into the storage cavity to increase the air pressure in the storage cavity, so as to discharge the contaminant from the storage cavity.

[0035] The recycling component, cleaning module, cleaning equipment, cleaning system, and cleaning method of this application include a storage component that can switch between a first state and a second state. The volume of the storage cavity when the storage component is in the first state is smaller than the volume of the storage cavity when the storage component is in the second state. When the storage component needs to store contaminants, it can be in the second state. When the storage component needs to be cleaned, it can switch to the first state. Because the volume of the storage cavity is smaller in the first state, liquid entering the storage cavity can more easily reach all parts of the storage cavity during cleaning, thereby improving the cleaning efficiency, reducing cleaning dead zones, simplifying the cleaning of the storage component, and achieving a better cleaning effect.

[0052] 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.

[0053] 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.

[0054] After cleaning the surface to be cleaned, the mop of the cleaning module will have wastewater on it. If the mop continues to clean the surface with wastewater, the cleaning effect will be poor. Therefore, the cleaning robot can be equipped with a wastewater tank for recycling the wastewater on the mop, thereby improving the cleaning effect on the surface to be cleaned. Currently, wastewater tanks usually have a self-cleaning function, that is, they can automatically clean the wastewater tank when wastewater is discharged. However, the current self-cleaning function of the wastewater tank has a poor cleaning effect. To solve this problem, this application provides a recycling component 100 (… Figure 1 (as shown), cleaning module ( Figure 1 (as shown), cleaning equipment 1000 ( Figure 7 (as shown), Cleaning System 10000 ( Figure 8 (as shown) and cleaning methods.

[0055] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In a first aspect, embodiments of this application provide a recycling assembly 100, which includes a wastewater tank 10 and a storage component 30. The wastewater tank 10 includes a tank body that encloses a receiving cavity 11. The storage component 30 is installed in the receiving cavity 11 and has a storage cavity 31 for storing waste. The storage component 30 is deformable to switch between a first state and a second state. When the storage component 30 is in the first state, the volume of the storage cavity 31 is smaller than the volume of the storage cavity 31 when the storage component 30 is in the second state.

[0056] Secondly, the present application provides a cleaning module including a body 20, a mopping component, and a recycling component 100, wherein the mopping component and the recycling component 100 are both disposed on the body 20.

[0057] Specifically, please combine 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 collect the dirt generated during cleaning, thereby preventing dirt from falling onto the surface. The cleaning module 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, a floor, marble surface, or glass surface. 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 robotic vacuum cleaner, a robotic mop, a robotic vacuum and mop combo, a handheld floor scrubber, etc. A sweeping robot can be used to sweep surfaces, a mopping robot can be used to wipe surfaces, and a sweeping-and-mopping robot can integrate the functions of both. That is, a sweeping-and-mopping robot can sweep surfaces and also wipe surfaces, while a handheld floor scrubber can perform wet cleaning (wet cleaning refers to wetting the roller or belt to wipe the floor and collect solid-liquid mixed waste) using a roller or belt. The cleaning equipment 1000 in this application is illustrated using a sweeping-and-mopping robot as an example.

[0058] In some embodiments, the cleaning device 1000 may include a tracked cleaning robot or a roller-type cleaning robot. When the cleaning device 1000 is a tracked cleaning robot, the mopping component is a tracked mopping component. When the cleaning device 1000 is a roller-type cleaning robot, the mopping component is a roller-type mopping component. Both tracked and roller-type mopping components can clean the surface to be cleaned by rotating, and the cleaning device 1000 achieves a good cleaning effect on the surface. This application uses a tracked cleaning robot as an example for explanation. When the cleaning device 1000 is a tracked cleaning robot, the cleaning module can clean the mopping component while it rotates to clean the surface, thus keeping the mopping component relatively clean, and the cleaning module achieves a good cleaning effect on the surface.

[0059] Please see Figure 1 and Figure 2The wastewater tank 10 is a structure for loading the storage component 30. The wastewater tank 10 can be installed on the body 20 of the cleaning module. When the wastewater tank 10 is installed on the body 20 of the cleaning module, the wastewater tank 10 can be detachably or non-detachably connected to the body 20. Detachable connections include, but are not limited to, threaded connections, screw connections, or snap-fit ​​connections, while non-detachable connections include, but are not limited to, welding, gluing, or interference fits. When the wastewater tank 10 is detachably connected to the body 20, it can be easily removed from the body 20 for repair in case of damage. When the wastewater tank 10 is non-detachably connected to the body 20, the wastewater tank 10 and the body 20 can be integrally formed, simplifying the processing steps of the cleaning module. The receiving cavity 11 is a spatial structure for installing the storage component 30 therein, and the volume of the receiving cavity 11 can be greater than or equal to the volume of the storage component 30 in its second state. In one embodiment, the wastewater tank 10 only includes a housing, which surrounds the receiving cavity 11, and the storage component 30 is installed in the housing. In another embodiment, the sewage tank 10 includes a tank body and may also include a cover body. The tank body and the cover body together form a receiving cavity 11, and the storage component 30 is installed in the receiving cavity 11 formed by the tank body and the cover body.

[0060] The materials used for the enclosure include, but are not limited to, metal or plastic. Metal materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys. When the enclosure is made of metal, it offers higher strength and a longer service life. When the enclosure is made of plastic, it offers lower material costs and lighter weight, making it easier to transport and handle. The cross-sectional shape of the enclosure in the horizontal plane can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0061] Please see Figure 2 While the cleaning module is cleaning the surface to be cleaned, the recycling component 100 can clean the mop and collect the dirt from it. When the recycling component 100 is cleaning the mop, its scraping mechanism can remove dirt from the mop. The storage unit 30 is used to store the dirt scraped off by the scraping mechanism to prevent it from falling onto the surface to be cleaned. The dirt here can include liquid wastewater and solid dirt. The storage unit 30 can be detachably connected to the wastewater tank 10, allowing it to be removed from the wastewater tank 10 for repair or replacement in case of damage.

[0062] Please see Figures 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. Thus, the storage member 30 can be deformed to a first state ( Figure 3 and Figure 4 (as shown) and the second state ( Figure 5 and Figure 6 switch between the states shown in Figure 6 . 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 may satisfy: A < B. When the storage member 30 needs to store dirt, the storage member 30 may 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 is cleaning the surface to be cleaned, the dirt on the mopping 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.

[0063] When the sewage in the storage cavity 31 needs to be discharged outside the storage member 30, the storage member 30 can be switched from the second state to the first state. At this time, the volume of the storage cavity 31 decreases, and the storage member 30 can squeeze the dirt in the storage cavity 31, so that the dirt in the storage cavity 31 can be quickly discharged outside the storage member 30. When the dirt is discharged from the storage cavity 31, some dirt may remain on the inner side wall of the storage member 30. When the storage member 30 is switched from the second state to the first state, the volume of the storage member 30 rapidly decreases, and some dirt is easily detached from the inner side wall of the storage member 30, which is convenient for cleaning the storage member 30. When the storage member 30 is in the second state, the volume of the storage cavity 31 is larger. When the storage member 30 needs to be cleaned, when external liquid enters the storage cavity 31, it is difficult for the liquid to flow to all positions of the inner side wall of the storage member 30, so the cleaning effect on the storage member 30 is relatively poor. In this application, after the storage member 30 is switched from the second state to the first state, the storage member 30 is cleaned. At this time, the volume of the storage cavity 31 is smaller. When external liquid enters the storage cavity 31, the liquid can flow through all positions of the inner side wall of the storage member 30, and the liquid can carry the dirt on the inner side wall of the storage member 30 and flow out of the storage member 30, so the cleaning effect of the storage member 30 is relatively good. The liquid here can be but is not limited to clean water, cleaning liquid or a mixed liquid added with cleaning liquid.

[0064] In the recycling component 100 of this application embodiment, the storage component 30 can switch between a first state and a second state, and the volume of the storage cavity 31 when the storage component 30 is in the first state is smaller than the volume of the storage cavity 31 when the storage component 30 is in the second state. When the storage component 30 needs to store contaminants, it can be in the second state. When the storage component 30 needs to be cleaned, it can switch to the first state. Because the volume of the storage cavity 31 is smaller in the first state, when cleaning the storage cavity 31, the liquid entering the storage cavity 31 can more easily reach all parts of the storage cavity, thereby improving the cleaning efficiency of the storage cavity, reducing cleaning dead spots, and thus making the cleaning of the storage component 30 simpler and the cleaning effect of the storage component 30 better.

[0065] The following description, in conjunction with the accompanying drawings, further explains the recycling component 100.

[0066] Please see Figures 3 to 6 In some embodiments, when the storage member 30 is in a first state, the storage member 30 is spaced apart from at least one side wall of the sewage tank 10; when the storage member 30 is in a second state, the storage member 30 is in contact with at least one side wall of the sewage tank 10.

[0067] In the first state, the storage component 30 can be in its natural state, at which point the volume of the storage cavity 31 can be its minimum volume. This allows external liquid to easily flow through various points on the inner wall of the storage component 30 when it enters the storage cavity 31, resulting in better cleaning of the storage component 30. In the first state, the volume of the storage component 30 is much smaller than the volume of the wastewater tank 10. When the storage component 30 is installed in the receiving cavity 11, it can be spaced apart from multiple side walls of the wastewater tank 10.

[0068] When the cross-section of the sewage tank 10 in the horizontal plane is circular (the sewage tank 10 is a cylindrical structure), the sewage tank 10 includes three side walls (top wall, bottom wall, and side walls). In this case, when the storage member 30 is in the first state, the storage member 30 can be spaced apart from one of the side walls of the sewage tank 10, or from two of the side walls, or even from all three side walls. When the cross-section of the sewage tank 10 in the horizontal plane is quadrilateral (the sewage tank 10 is a prism structure), the sewage tank 10 includes six side walls (the six faces of a prism). In this case, when the storage member 30 is in the first state, the storage member 30 can be spaced apart from one of the side walls of the sewage tank 10, or from two of the side walls, or even from all six side walls.

[0069] When the storage component 30 is in the second state, it is in an expanded state. With the storage component 30 in contact with at least one side wall of the wastewater tank 10, the storage cavity 31 has a larger volume and can hold more waste. Preferably, the storage component 30 can completely fill the receiving cavity 11. In this case, the storage component 30 is in contact with all side walls of the wastewater tank 10, and the volume of the storage cavity 31 can be the maximum achievable volume, allowing it to hold a larger amount of waste.

[0070] Please see Figures 3 to 6 In some embodiments, the space inside the receiving cavity 11 other than the storage member 30 is the receiving space 13; when the storage member 30 is in the first state, the air pressure of the storage cavity 31 is less than or equal to the air pressure of the receiving space 13; when the storage member 30 is in the second state, the air pressure of the storage cavity 31 is greater than the air pressure of the receiving space 13.

[0071] Specifically, the volume of the storage cavity 31 plus the volume of the receiving space 13 equals the volume of the receiving cavity 11. When the storage device 30 is in the first state, the volume of the storage cavity 31 is smaller, and the volume of the receiving space 13 is larger. When the storage device 30 is in the second state, the volume of the storage cavity 31 is larger, and the volume of the receiving space 13 is smaller.

[0072] When the air pressure in the storage cavity 31 is lower than the air pressure in the containing space 13, the air pressure in the containing space 13 will compress the storage component 30, resulting in a smaller volume of the storage component 30 and a smaller volume of the storage cavity 31. When external liquid enters the storage cavity 31 to clean the inner wall of the storage component 30, the liquid can flow through all parts of the inner wall of the storage cavity 31, resulting in a better cleaning effect on the storage component 30. When the air pressure in the storage cavity 31 is equal to the air pressure in the containing space 13, the storage component 30 is in its natural state. The storage component 30 in its natural state has a smaller volume, resulting in a smaller volume of the storage cavity 31. When external liquid enters the storage cavity 31 to clean the inner wall of the storage component 30, the liquid can flow through all parts of the inner wall of the storage cavity 31, resulting in a better cleaning effect on the storage component 30.

[0073] When the air pressure in the storage cavity 31 is greater than the air pressure in the containing space 13, the storage component 30 will expand towards the containing space 13. Once the storage cavity 31 is in contact with all the side walls of the sewage tank 10, the storage component 30 can no longer expand. At this time, the storage component 30 is in the second state, and the volume of the storage cavity 31 is larger, so that the storage cavity 31 can hold more sewage.

[0074] Please see Figure 3 and Figure 4In some embodiments, when the storage component 30 is in its first state, it is tubular in shape. In one example, the cross-sectional area of ​​each location of the storage component 30 is equal, and the cross-sectional area of ​​each location is relatively small. When external liquid enters the storage cavity 31, the liquid can easily and smoothly flow into each location of the inner wall of the storage component 30 to rinse the inner wall of the storage component 30, resulting in a better cleaning effect. In this case, the structure of the storage component 30 is relatively regular, and the processing of the storage component 30 is relatively simple. In another example, in the direction of liquid flow within the storage cavity 31, the cross-sectional area of ​​the downstream storage component 30 is less than or equal to the cross-sectional area of ​​the upstream storage component 30. When external liquid flows within the storage cavity 31, the liquid can more easily contact each location of the inner wall of the storage component 30, thereby rinsing the inner wall of the storage component 30 and resulting in a better cleaning effect.

[0075] Please see Figure 5 and Figure 6 In other embodiments, when the storage member 30 is in the second state, its shape matches the shape of the receiving cavity 11. Since the storage member 30 is an elastomer, its shape is variable. In the second state, the storage member 30 can contact all sidewalls of the wastewater tank 10, thus matching the shape of the receiving cavity 11. At this time, the storage member 30 almost fills the receiving cavity 11. When the storage member 30 almost fills the receiving cavity 11, the volume of the storage cavity 31 is the maximum volume that the storage cavity 31 can achieve, thus allowing the storage member 30 to hold a larger amount of waste.

[0076] Please see Figures 3 to 6 In some embodiments, when the storage component 30 is in the first state, it is tubular in shape; and when the storage component 30 is in the second state, its shape matches the shape of the receiving cavity 11. When the storage component 30 needs to store contaminants, it can be in the second state, at which point the volume of the storage cavity 31 reaches its maximum achievable volume, allowing the storage component 30 to store a larger amount of contaminants. When the storage component 30 needs cleaning, it can be in the first state, at which point external liquid can easily and smoothly flow into various locations on the inner wall of the storage component 30 to rinse these locations, resulting in a better cleaning effect.

[0077] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In some embodiments, the sewage tank 10 is provided with a first opening 14 and a second opening 15 spaced apart from each other. The two ends of the storage member 30 are respectively connected to the first opening 14 and the second opening 15. The first opening 14 is used to allow external sewage to enter the storage cavity 31, and the second opening 15 is used to adjust the air pressure in the storage cavity 31.

[0078] Specifically, both the first opening 14 and the second opening 15 are connected to the storage cavity 31. When the cleaning module is cleaning the surface to be cleaned and the storage unit 30 is in the second state, the first opening 14 allows dirt scraped off from the mop to enter the storage cavity 31, where it is stably stored. When dirt in the storage unit 30 needs to be drained or the storage unit 30 needs to be cleaned, the first opening 14 can also be used to drain dirt from the storage cavity 31 to the outside of the storage unit 30. In the height direction H of the wastewater tank 10, the first opening 14 can be located at the bottom of the wastewater tank 10, so that dirt in the storage cavity 31 can flow smoothly out of the storage unit 30 due to gravity, leaving less dirt in the storage cavity 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.

[0079] When the cleaning module is cleaning the surface to be cleaned and the storage unit 30 is in the second state, the dirt scraped off by the scraper on the wiping unit needs to be stored in the storage cavity 31. At this time, the second opening 15 is used to allow gas to flow out of the storage cavity 31. The air pressure inside the storage cavity 31 is lower than the external air pressure, so the dirt scraped off by the scraper can flow into the storage cavity 31. During the process of the storage unit 30 switching from the second state to the first state, when the dirt in the storage cavity 31 needs to be discharged from the storage unit 30, the second opening 15 is used to allow external gas to enter the storage cavity 31. The air pressure inside the storage cavity 31 is higher than the external air pressure, so the dirt in the storage cavity 31 can flow out of the storage unit 30 more quickly. In the height direction H of the wastewater tank 10, the second opening 15 can be provided at the top of the wastewater tank 10. In this way, when there is dirt stored in the storage cavity 31, the dirt can be prevented from clogging the second opening 15, and the effective volume of the storage cavity 31 can also be increased.

[0080] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5Furthermore, in some embodiments, the recycling component 100 further includes a first gas suction member 40, which may be disposed on the body 20 of the cleaning module. The first gas suction member 40 is connected to the second opening 15. When the storage unit 30 is in the second state, the first gas suction member 40 is used to extract gas from the storage cavity 31 through the second opening 15 to reduce the gas pressure in the storage cavity 31, so that dirt enters and / or remains in the storage cavity 31. The first gas suction member 40 may be any device capable of suctioning gas, such as a fan or air pump.

[0081] When the storage unit 30 is in the second state, the storage cavity 31 has a larger volume and can hold more contaminants. Even when the first gas suction member 40 extracts gas from the storage cavity 31, reducing the gas pressure, the pressure inside the storage cavity 31 remains greater than the pressure in the accommodating space 13. Therefore, even when the first gas suction member 40 extracts gas from the storage cavity 31, the state of the storage unit 30 does not change. In other words, the storage unit 30 remains stably in the second state, the volume of the storage cavity 31 remains constant, and thus the storage cavity 31 can hold a larger amount of contaminants.

[0082] When the cleaning module cleans the surface to be cleaned and the dirt from the wiping component is scraped off by the scraper, the first gas suction component 40 is activated. When the first gas suction component 40 draws gas from the storage cavity 31 through the second opening 15, the storage cavity 31 is under negative pressure. The air pressure inside the storage cavity 31 is lower than the external air pressure, and the dirt scraped off by the scraper flows into the storage cavity 31. After the dirt enters the storage cavity 31, if the first gas suction component 40 can remain sealed after stopping operation, it can stop working, and the storage cavity 31 can maintain a negative pressure state, allowing the dirt to be stably stored in the storage cavity 31, thus preventing the dirt from flowing back from the storage cavity 31 to the surface to be cleaned; if the first gas suction component 40 cannot remain sealed after stopping operation, it cannot stop working and needs to continuously suction the storage cavity 31 to use the force generated by the negative pressure to counteract the gravity of the dirt entering the storage cavity 31, preventing the dirt from flowing out from the first opening 14.

[0083] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, during the process of switching the storage unit 30 from the second state to the first state, the first gas suction unit 40 is also used to pump air into the storage cavity 31 through the second opening 15 to increase the air pressure in the storage cavity 31 so that the dirt can be quickly discharged from the storage cavity 31.

[0084] During the transition from the second state to the first state of the storage device 30, the volume of the storage cavity 31 gradually decreases. The contaminants stored in the storage cavity 31 are subjected to gravity and compression by the storage device 30, causing them to flow out quickly. In some embodiments, the first gas suction device 40 switches from extracting gas from the storage cavity 31 to pumping gas into it. When the first gas suction device 40 pumps gas into the storage cavity 31 through the second opening 15, the gas pressure inside the storage cavity 31 is greater than the external gas pressure, thus accelerating the discharge of contaminants from the storage cavity 31. In other embodiments, the gas pressure within the receiving space 13 can be increased to gradually exceed the gas pressure inside the storage cavity 31, thereby using the gas pressure to compress the storage device 30, reducing its volume and causing it to transition from the second state to the first state. At this point, almost all the contaminants in the storage cavity 31 can be discharged, leaving relatively little contaminant remaining. The number of second openings 15 can be, but is not limited to, one, two, three, or more. When there is only one second opening 15, the structure of the sewage tank 10 is relatively simple, and its manufacturing is easier. When there are multiple second openings 15, the first gas suction member 40 is connected to all of the second openings 15. The first gas suction member 40 can simultaneously extract gas from the storage cavity 31 through the multiple second openings 15, enabling it to quickly extract gas from the storage cavity 31 with high efficiency. The first gas suction member 40 can also simultaneously pump air into the storage cavity 31 through the multiple second openings 15, allowing the waste in the storage cavity to be quickly discharged outside the storage cavity 30. In this embodiment, the number of second openings 15 is one.

[0085] When the first gas suction member 40 is used to extract gas from the storage chamber 31 and also to pump 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 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 to allow gas from the first gas suction member 40 to enter the storage chamber 31, the structure of the wastewater tank 10 is relatively simple, and the processing of the wastewater tank 10 is relatively easy.

[0086] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In some embodiments, waste can be discharged from the storage cavity 31 through the first opening 14. In this case, the first opening 14 is used to discharge the waste stored in the storage cavity 31 to the outside of the storage unit 30. The first opening 14 is also used to discharge the waste in the storage cavity 31 to the outside of the storage unit 30 when external liquid is used to clean the storage unit 30. Thus, the structure of the wastewater tank 10 is relatively simple, and the manufacturing of the wastewater tank 10 is relatively easy.

[0087] In another embodiment, the wastewater tank 10 is further provided with a third opening, which communicates with the storage cavity 31. Waste can be discharged from the storage cavity 31 through the third opening. During the transition of the storage unit 30 from a second state to a first state, the third opening is used to allow waste in the storage cavity 31 to drain out of the storage unit 30. When the storage unit 30 is cleaned with external liquid, the third opening is also used to allow waste in the storage cavity 31 to flow out of the storage unit 30. Preferably, in the height direction H of the wastewater tank 10, the third opening can be located at the bottom of the wastewater tank 10, so that waste in the storage cavity 31 can flow smoothly out of the storage unit 30 through the third opening due to gravity, resulting in less waste remaining in the storage cavity 31.

[0088] With the first opening 14 used to allow waste to enter the storage unit 30, and the third opening used to allow waste in the storage cavity 31 to drain out of the storage unit 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage cavity 31 through the first opening 14, and waste in the storage cavity 31 can also quickly flow out through the third opening. Furthermore, if the first opening 14 fails, it will not affect the function of the third opening. Similarly, if the third opening fails, it will not affect the function of the first opening 14, resulting in good stability and reliability of the wastewater tank 10.

[0089] When the wastewater tank 10 has a third opening, the third opening is used to discharge the waste in the storage cavity 31 to the outside of the storage unit 30. At this time, the first opening 14 can be used to allow gas to enter the storage cavity 31. Preferably, in the height direction H of the wastewater tank 10, the third opening can be located at the bottom of the wastewater tank 10, and the first opening 14 can be located at the top of the wastewater tank 10. When the waste in the storage cavity 31 needs to be discharged, the first gas suction unit 40 can pump air into the storage cavity 31 through the second opening 15, so that the waste in the storage cavity 31 can be discharged from the third opening to the outside of the wastewater tank 10. When the cleaning module is cleaning the surface to be cleaned, the third opening is in a closed state. When the waste in the storage cavity 31 needs to be discharged, the third opening is opened to allow the waste to flow out to the outside of the wastewater tank 10, thereby avoiding the problem of the waste in the storage cavity 31 flowing back to the surface to be cleaned when the cleaning module is cleaning the surface to be cleaned.

[0090] Please see Figure 1 , Figure 2 , Figure 3and Figure 5 Furthermore, in some embodiments, the recovery assembly 100 further includes a second gas suction member disposed on the body 20 and connected to the second opening 15. During the process of the storage unit 30 switching from the second state to the first state, the second gas suction member is used to pump air into the storage cavity 31 through the second opening 15 to increase the air pressure in the storage cavity 31, so that the waste is quickly discharged from the storage cavity 31. The second gas suction member can be any device capable of suctioning gas, such as a fan or air pump.

[0091] The second gas suction component is disposed on the main body 20 and spaced apart from the first gas suction component 40. During the transition from the second state to the first state of the storage component 30, the volume of the storage cavity 31 gradually decreases. The contaminants stored in the storage cavity 31 are subjected to gravity and compression by the storage component 30, causing them to flow out of the storage component 30 rapidly. At this time, the second gas suction component is activated. With the second gas suction component pumping air into the storage cavity 31 through the second opening 15, the air pressure inside the storage cavity 31 is greater than the external air pressure, thereby accelerating the discharge of contaminants from the storage cavity 31. Almost all the contaminants in the storage cavity 31 are discharged outside the storage component 30, leaving relatively little contaminant remaining in the storage cavity 31.

[0092] When the first gas suction member 40 is used to extract gas from the storage cavity 31, and the second gas suction member is used to pump air into the storage cavity 31, the second gas suction member can quickly start and pump air into the storage cavity 31 when contaminants need to be discharged from the storage cavity 31. The first gas suction member 40 does not need to switch from a suction state to a pumping state; the use of the second gas suction member saves the time of this switching process, allowing contaminants to be quickly discharged from the first opening 14 to the outside of the storage member 30. Furthermore, the division of labor between the first and second gas suction members is clear, and both have a long service life. In some embodiments, since the second gas suction member is used to pump air into the storage cavity 31, the first gas suction member 40 can also be a pump with only a suction function to save costs.

[0093] In some embodiments, waste can be discharged from the storage cavity 31 through the first opening 14. When the first opening 14 is used to allow waste from the mopping component to enter the storage cavity 31, and the first opening 14 is also used to allow waste in the storage cavity 31 to be discharged outside the storage component 30, the structure of the wastewater tank 10 is relatively simple, and the manufacturing of the wastewater tank 10 is relatively easy.

[0094] In other embodiments, waste is discharged from the storage cavity 31 through a third opening. With the first opening 14 for waste to enter the storage unit 30 and the third opening for waste to drain from the storage cavity 31 outside the storage unit 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage cavity 31 through the first opening 14, and waste in the storage cavity 31 can also quickly flow out through the third opening. Furthermore, if the first opening 14 fails, it will not affect the function of the third opening. In the event of a failure of the third opening, the third opening will not affect the function of the first opening 14, resulting in good stability and reliability of the wastewater tank 10.

[0095] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the storage cavity 31 is connected to the liquid supply unit 50. When the storage unit 30 is in the first state, the liquid supply unit 50 is used to supply cleaning liquid to the storage cavity 31 to clean the storage cavity 31. The liquid supply unit 50 can be disposed on the body 20 of the cleaning module, or on the cleaning equipment, or on the cleaning base station, or from an external water source such as tap water.

[0096] In some embodiments, the liquid supply unit 50 is connected to the second opening 15, and when the storage unit 30 is in the first state, the liquid supply unit 50 is used to supply cleaning liquid to the storage cavity 31 through the second opening 15. Here, the cleaning liquid is the same as the "liquid" referred to above, and the cleaning liquid includes clean water or a cleaning liquid containing cleaning solution.

[0097] During the transition from the second state to the first state, contaminants in the storage cavity 31 flow out of the storage unit 30 through the first opening 14 or the third opening. When the storage unit 30 is in the first state, most of the contaminants in the storage cavity 31 have been discharged, but some contaminants may remain in the storage unit 30. If the storage unit 30 requires cleaning, the liquid supply unit 50 provides cleaning liquid to the storage unit 30. At this time, the second opening 15 also allows liquid to enter the storage cavity 31. With the second opening 15 used to regulate the air pressure in the storage cavity 31 and also to allow cleaning liquid to enter the storage cavity 31, the structure of the wastewater tank 10 is relatively simple, and its manufacturing is relatively easy.

[0098] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5When the liquid supply unit 50 supplies cleaning liquid into the storage cavity 31 through the second opening 15, the cleaning liquid, after entering the storage cavity 31, can carry the dirt in the storage cavity 31 out to the outside of the storage unit 30. At this time, the storage unit 30 is in its first state, and the volume of the storage cavity 31 is small. The cleaning liquid entering the storage cavity 31 can flow through various positions on the inner wall of the storage unit 30, thus carrying the dirt from various positions on the inner wall of the storage unit 30 out of the storage cavity 31, resulting in a better cleaning effect on the storage unit 30. When the second opening 15 is located at the top of the wastewater tank 10, after the cleaning liquid enters the storage cavity 31 through the second opening 15, the cleaning liquid will flow down the inner wall of the storage unit 30 due to gravity, carrying the dirt from various positions on the inner wall of the storage unit 30 out of the storage cavity 31, resulting in a better cleaning effect on the storage unit 30.

[0099] In one embodiment, the liquid supply unit 50 may be a clean water tank for the cleaning module, connected to the second opening 15. When the storage unit 30 is in a first state and requires cleaning, the clean water tank supplies cleaning liquid to the storage cavity 31 through the second opening 15. The liquid supply unit 50 may also include a valve located between the clean water tank and the second opening 15. When the storage unit 30 does not require cleaning, the valve is closed, preventing the cleaning liquid from the clean water tank from flowing into the storage cavity 31 through the second opening 15. When the storage unit 30 requires cleaning and is in the first state, the valve is opened, allowing the cleaning liquid from the clean water tank to flow into the storage cavity 31 through the second opening 15 and clean the storage unit 30.

[0100] In another embodiment, the liquid supply unit 50 may be an external water source connected to the second opening 15. When the storage unit 30 is in the first state and needs cleaning, the external water source supplies cleaning liquid to the storage cavity 31 through the second opening 15. The liquid supply unit 50 may also include a valve located between the external water source and the second opening 15. When the storage unit 30 does not need cleaning, the valve is closed, preventing cleaning liquid from the external water source from flowing into the storage cavity 31 through the second opening 15. When the storage unit 30 needs cleaning and is in the first state, the valve is opened, allowing cleaning liquid from the external water source to flow into the storage cavity 31 through the second opening 15 and clean the storage unit 30.

[0101] In some embodiments, when the cleaning liquid enters and cleans the storage cavity 31, the first opening 14 is used to allow the waste in the storage cavity 31 to flow out to the outside of the storage member 30. When the first opening 14 is used to allow the waste from the mopping member to enter the storage cavity 31, and the first opening 14 is also used to allow the waste in the storage cavity 31 to be discharged out to the outside of the storage member 30, the structure of the wastewater tank 10 is relatively simple, and the manufacturing of the wastewater tank 10 is relatively easy.

[0102] In other embodiments, when cleaning liquid enters and cleans the storage cavity 31, the third opening is used to allow waste in the storage cavity 31 to flow out of the storage unit 30. When the first opening 14 is used to allow waste to enter the storage unit 30, and the third opening is used to allow waste in the storage cavity 31 to flow out of the storage unit 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage cavity 31 from the first opening 14, and waste in the storage cavity 31 can also quickly flow out from the third opening. Furthermore, if the first opening 14 fails, it will not affect the function of the third opening. In the event of a failure of the third opening, it will not affect the function of the first opening 14, resulting in good stability and reliability of the wastewater tank 10.

[0103] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the wastewater tank 10 is further provided with a fourth opening 17, which is connected to the storage cavity 31; the liquid supply unit 50 is connected to the fourth opening 17, and when the storage unit 30 is in the first state, the liquid supply unit 50 is used to supply cleaning liquid to the storage cavity 31 through the fourth opening 17.

[0104] During the transition from the second state to the first state of the storage unit 30, contaminants in the storage cavity 31 flow out of the storage unit 30 through either the first opening 14 or the third opening. When the storage unit 30 is in the first state, most of the contaminants in the storage cavity 31 have already been discharged. Some contaminants may remain in the storage unit 30. If the storage unit 30 requires cleaning, the liquid supply unit 50 provides cleaning liquid to the storage unit 30. At this time, the fourth opening 17 is used to allow liquid to enter the storage cavity 31. With the second opening 15 used to regulate the air pressure in the storage cavity 31 and the fourth opening 17 used to allow cleaning liquid to enter the storage cavity 31, the second opening 15 and the fourth opening 17 do not interfere with each other. If the second opening 15 malfunctions, it will not affect the function of the fourth opening 17. Similarly, if the fourth opening 17 malfunctions, it will not affect the function of the second opening 15, indicating good stability and reliability of the wastewater tank 10.

[0105] When the liquid supply unit 50 supplies cleaning liquid into the storage cavity 31 through the fourth opening 17, the cleaning liquid, after entering the storage cavity 31, can carry the dirt in the storage cavity 31 out to the outside of the storage unit 30. At this time, the storage unit 30 is in its first state, and the volume of the storage cavity 31 is small. The cleaning liquid entering the storage cavity 31 can flow through various positions on the inner wall of the storage unit 30, thus carrying the dirt from various positions on the inner wall of the storage unit 30 out of the storage cavity 31, resulting in a better cleaning effect on the storage unit 30. When the fourth opening 17 is located at the top of the wastewater tank 10, after the cleaning liquid enters the storage cavity 31 through the fourth opening 17, the cleaning liquid will flow down the inner wall of the storage unit 30 due to gravity, carrying the dirt from various positions on the inner wall of the storage unit 30 out of the storage cavity 31, resulting in a better cleaning effect on the storage unit 30.

[0106] In some embodiments, when the cleaning liquid enters and cleans the storage cavity 31, the first opening 14 is used to allow the waste in the storage cavity 31 to flow out to the outside of the storage member 30. When the first opening 14 is used to allow the waste from the mopping member to enter the storage cavity 31, and the first opening 14 is also used to allow the waste in the storage cavity 31 to be discharged out to the outside of the storage member 30, the structure of the wastewater tank 10 is relatively simple, and the manufacturing of the wastewater tank 10 is relatively easy.

[0107] In other embodiments, when cleaning liquid enters and cleans the storage cavity 31, the third opening is used to allow waste in the storage cavity 31 to flow out of the storage unit 30. When the first opening 14 is used to allow waste to enter the storage unit 30, and the third opening is used to allow waste in the storage cavity 31 to flow out of the storage unit 30, the first opening 14 and the third opening do not interfere with each other. Waste can quickly enter the storage cavity 31 from the first opening 14, and waste in the storage cavity 31 can also quickly flow out from the third opening. Furthermore, if the first opening 14 fails, it will not affect the function of the third opening. In the event of a failure of the third opening, it will not affect the function of the first opening 14, resulting in good stability and reliability of the wastewater tank 10.

[0108] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the sewage tank 10 is further provided with a fifth opening 18, which is connected to the containment space 13 and is used to adjust the air pressure in the containment space 13.

[0109] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In some embodiments, the recovery assembly 100 further includes a third gas suction member 60, which is disposed on the body 20 and connected to the fifth opening 18. The third gas suction member 60 is used to extract gas from the containing space 13 through the fifth opening 18 to reduce the gas pressure in the containing space 13, thereby switching the storage unit 30 from the first state to the second state. The third gas suction member 60 can be any device capable of suctioning gas, such as a fan or air pump.

[0110] Specifically, when the cleaning module is cleaning the surface to be cleaned, the storage unit 30 needs to store the dirt from the mopping component. At this time, the storage unit 30 needs to be in the second state, so that the storage cavity 31 has a larger volume and can hold more dirt. When the storage unit 30 needs to switch from the first state to the second state, the third gas suction component 60 is activated, and the fifth opening 18 is used for the third gas suction component 60 to extract gas from the receiving space 13. When the gas pressure in the receiving space 13 is lower than the gas pressure in the storage cavity 31, the elastic storage unit 30 will expand, thus allowing the storage unit 30 to switch from the first state to the second state. During the process of loading dirt into the storage cavity 31, or in order to ensure that the storage component 30 is stable in the second state, the third gas suction component 60, which can remain sealed after stopping work, can stop working when the storage component 30 reaches the second state; while the third gas suction component 60, which cannot remain sealed after stopping work, needs to work continuously to keep the storage component 30 stable in the second state and prevent the elastic storage component 30 from deforming back to the first state and causing dirt to flow out of the storage cavity 31.

[0111] When the first gas suction member 40 draws gas from the storage cavity 31 through the second opening 15, the third gas suction member 60 also works at the same time, so that the gas pressure in the accommodating space 13 is always lower than the gas pressure in the storage cavity 31, the storage member 30 can be kept in the second state, and the storage cavity 31 can be loaded with more dirt.

[0112] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the third gas suction member 60 is also used to increase the gas pressure in the receiving space 13 by pumping gas into the receiving space 13 through the fifth opening 18, so as to switch the storage member 30 from the second state to the first state.

[0113] When waste in storage unit 30 needs to be discharged from storage cavity 31, the third gas suction unit 60 switches from extracting gas from receiving space 13 to pumping gas into receiving space 13. The fifth opening 18 also allows gas from the third gas suction unit 60 to enter receiving space 13. With the fifth opening 18 used for both allowing gas from receiving space 13 to flow into the third gas suction unit 60 and allowing gas from the third gas suction unit 60 to enter receiving space 13, the structure of wastewater tank 10 is relatively simple, and its manufacturing is relatively easy.

[0114] When the storage unit 30 needs to switch from the second state to the first state, the third gas suction unit 60 is activated, pumping air into the receiving space 13 through the fifth opening 18. When the air pressure in the receiving space 13 is greater than the air pressure in the storage cavity 31, the elastic storage unit 30 is compressed, thus enabling the storage unit 30 to switch from the second state to the first state. When the third gas suction unit 60 switches the storage unit 30 from the second state to the first state, the first gas suction unit 40 or the second gas suction unit can simultaneously pump air into the storage cavity 31, thereby accelerating the discharge of contaminants from the storage cavity 31 to the outside of the storage cavity 31. Furthermore, after the storage unit 30 switches from the second state to the first state, the volume of the storage cavity 31 decreases, which is beneficial for cleaning the storage unit 30.

[0115] When the third gas suction member 60 is used to extract gas from the containment space 13 and also to pump gas into the containment space 13, the structure of the recovery assembly 100 is relatively simple and the number of components in the recovery assembly 100 is small, which can save costs.

[0116] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the recovery assembly 100 further includes a fourth gas suction device disposed on the body 20 and connected to a fifth opening 18. The fourth gas suction device is used to pump gas into the receiving space 13 through the fifth opening 18 to increase the gas pressure in the receiving space 13, thereby switching the storage unit 30 from the second state to the first state. The fourth gas suction device 40 can be any device capable of suctioning gas, such as a fan or air pump.

[0117] When contaminants in storage unit 30 need to be discharged from storage cavity 31, a fourth gas suction unit pumps air into receiving space 13. A fifth opening 18 also allows gas from the fourth gas suction unit to enter receiving space 13. When storage unit 30 needs to switch from a second state to a first state, the fourth gas suction unit is activated, pumping air into receiving space 13 through the fifth opening 18. When the air pressure in receiving space 13 is greater than the air pressure in storage cavity 31, the elastic storage unit 30 is compressed, allowing it to switch from the second state to the first state. When the fourth gas suction unit switches storage unit 30 from the second state to the first state, the first gas suction unit 40 or the second gas suction unit can pump air into storage cavity 31 individually or simultaneously, thereby accelerating the discharge of contaminants from storage cavity 31. Furthermore, after storage unit 30 switches from the second state to the first state, the volume of storage cavity 31 decreases, which facilitates both contaminant discharge and cleaning of storage unit 30.

[0118] When the third gas suction member 60 is used to extract gas from the containing space 13, and the fourth gas suction member is used to pump gas into the containing space 13, the fourth gas suction member can quickly start and pump gas into the containing space 13 when the storage unit 30 needs to switch from the second state to the first state. The third gas suction member 60 does not need to switch from the suction state to the pumping state; the use of the fourth gas suction member saves the time of this switching process, allowing the storage unit 30 to quickly switch from the second state to the first state. Furthermore, the division of labor between the third and fourth gas suction members is clear, and both have a long service life.

[0119] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the wastewater tank 10 is further provided with a sixth opening, which communicates with the containing space 13. A third gas suction member 60 reduces the gas pressure in the containing space 13 by drawing gas from it through the fifth opening 18, thereby switching the storage unit 30 from a first state to a second state. A fourth gas suction member increases the gas pressure in the containing space 13 by pumping gas into it through the sixth opening, thereby switching the storage unit 30 from the second state to the first state.

[0120] When contaminants in storage unit 30 need to be discharged from storage cavity 31, a fourth gas suction unit pumps air into receiving space 13. A sixth opening allows gas from the fourth gas suction unit to enter receiving space 13. When storage unit 30 needs to switch from a second state to a first state, the fourth gas suction unit is activated, pumping air into receiving space 13 through the sixth opening. When the air pressure in receiving space 13 is greater than or equal to the air pressure in storage cavity 31, the elastic storage unit 30 is compressed, allowing it to switch from the second state to the first state. When the fourth gas suction unit switches storage unit 30 from the second state to the first state, the first gas suction unit 40 or the second gas suction unit can pump air into storage cavity 31 individually or simultaneously, thereby accelerating the discharge of contaminants from storage cavity 31. Furthermore, after storage unit 30 switches from the second state to the first state, the volume of storage cavity 31 decreases, which facilitates both the discharge of contaminants and the cleaning of storage unit 30.

[0121] With the second opening 15 used to regulate the air pressure in the storage chamber 31 and the fourth opening 17 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, it will not affect the function of the fourth opening 17. If the fourth opening 17 fails, it will not affect the function of the second opening 15, thus the wastewater tank 10 has good stability and reliability.

[0122] Please see Figure 1 and Figure 2 In some embodiments, the recycling component 100 further includes a wastewater tank 70, a discharge component 80, and a connecting pipe 90. The wastewater tank 70 may be disposed on the body 20 of the cleaning module and is used to collect waste. The discharge component 80 may be disposed on the body 20 of the cleaning module and has a discharge port 81. The discharge component 80 communicates with the wastewater tank 70, and when the storage component 30 switches from the second state to the first state, the discharge port 81 is used to discharge waste from the wastewater tank 70. One end of the connecting pipe 90 communicates with the storage component 30, and the other end communicates with the wastewater tank 70.

[0123] 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 cavity 31. The waste in the sewage tank 70 can enter the storage cavity 31 through the connecting pipe 90, and the waste in the storage cavity 31 can also enter the sewage tank 70 through the connecting pipe 90.

[0124] In one embodiment, the connecting pipe 90 is connected to the first opening 14. When the cleaning module cleans the surface to be cleaned, the dirt from the mop enters the wastewater tank 70, flows from the wastewater tank 70 into the connecting pipe 90, and enters the storage cavity 31 through the first opening 14. When the dirt in the storage cavity 31 needs to be drained, the dirt in the storage cavity 31 flows from the first opening 14 into the connecting pipe 90, and is discharged from the drain device 80 through the wastewater tank 70. In another embodiment, the connecting pipe 90 is connected to both the first opening 14 and the third opening. When the cleaning module cleans the surface to be cleaned, the dirt from the mop enters the wastewater tank 70, flows from the wastewater tank 70 into the connecting pipe 90, and enters the storage cavity 31 through the first opening 14. When the dirt in the storage cavity 31 needs to be drained, the third opening is open, and the dirt in the storage cavity 31 can flow out of the wastewater tank 10 through the third opening.

[0125] The connecting pipe 90 can be made of, but is not limited to, metal, plastic, or rubber. When the connecting pipe 90 is made of metal, it has high strength, good wear resistance, and a long service life. When the connecting pipe 90 is made of plastic, it is lightweight and has a lower cost. When the connecting pipe 90 is made of rubber, it is highly flexible and has a long service life. The discharge component 80 is used to discharge waste from the wastewater tank 70 to the recycling assembly 100. The discharge component 80 can be made of, but is not limited to, metal or plastic. When the discharge component 80 is made of metal, it has high strength, good wear resistance, and a long service life. When the discharge component 80 is made of plastic, it is lightweight and has a lower cost.

[0126] The storage chamber 31, connecting pipe 90, sewage tank 70, and drain device 80 are connected in sequence. When the cleaning module is cleaning the surface to be cleaned, the dirt on the wiping device is scraped off by the scraping device, and the scraped dirt falls into the sewage tank 70. The third gas suction device 60 is activated, and the third gas suction device 60 draws gas from the receiving space 13 through the fifth opening 18. The air pressure in the storage chamber 31 is greater than the air pressure in the receiving space 13, and the storage device 30 expands, switching from the first state to the second state. The volume of the storage chamber 31 increases, and at this time, the storage chamber 31 can store the dirt that enters the sewage tank 70; and the first gas suction device 40 is also activated, and the first gas suction device 40 draws gas from the storage chamber 31 through the second opening 15. The storage chamber 31 is under negative pressure, so the dirt in the sewage tank 70 flows into the connecting pipe 90 and then into the storage chamber 31 through the first opening 14, and the dirt can be stored in the storage chamber 31. When contaminants (the contaminants here refer to those from the mopping components stored in storage cavity 31) need to be discharged, the third gas suction unit 60 or the fourth gas suction unit pumps air into the receiving space 13 through the fifth opening 18, or the fourth gas suction unit pumps air into the receiving space 13 through the sixth opening. The air pressure inside storage cavity 31 becomes lower than the air pressure inside receiving space 13, causing storage component 30 to contract and switch from the second state to the first state. Simultaneously, the first gas suction unit 40 or the second gas suction unit pumps air into storage cavity 31 through the second opening 15. When the air pressure inside storage cavity 31 becomes higher than the external air pressure, the contaminants inside storage cavity 31 pass through the connecting pipe 90 and the wastewater tank 70, and are discharged from the drain port 81.

[0127] During the cleaning process of storage component 30, storage component 30 is in its first state. At this time, storage component 30 has a tubular structure and the volume of storage cavity 31 is relatively small. When external liquid enters storage cavity 31, the liquid flows through various locations on the inner wall of storage component 30, carrying away contaminants from storage cavity 31 and flowing out through the first opening 14 or the third opening. As the liquid flows through connecting pipe 90, sewage tank 70, and drain device 80, it can flush connecting pipe 90, sewage tank 70, and drain device 80, thereby keeping them relatively clean.

[0128] Please see Figure 7 Thirdly, embodiments of this application provide a cleaning device 1000, which includes a body 300 and a recycling component 100 as described above, the recycling component 100 being disposed on the body 300.

[0129] Please see Figure 7 Fourthly, embodiments of this application provide a cleaning device 1000, which includes a body 300 and a cleaning module as described above, the cleaning module being disposed on the body 300.

[0130] In this regard, please combine Figure 3 and Figure 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 a second opening 15 or a fourth opening 17. When the storage unit 30 requires cleaning and is in a first state, the liquid supply unit supplies cleaning liquid to the storage cavity 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, which provides cleaning liquid to the storage unit 30 when it is in the first state. The liquid supply unit may also include a valve located between the clean water tank and the second opening 15 or the fourth opening 17. When the storage unit 30 does not require cleaning, the valve is closed, preventing cleaning liquid in the clean water tank from flowing into the storage cavity 31 through the second opening 15 or the fourth opening 17. When the storage unit 30 needs to be cleaned and the storage unit 30 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.

[0131] In the cleaning device 1000 of this application embodiment, the storage component 30 can switch between a first state and a second state, and the volume of the storage cavity 31 when the storage component 30 is in the first state is smaller than the volume of the storage cavity 31 when the storage component 30 is in the second state. When the storage component 30 needs to store dirt, it can be in the second state. When the storage component 30 needs to be cleaned, it can switch to the first state. Because the volume of the storage cavity 31 is smaller in the first state, when cleaning the storage cavity 31, the liquid entering the storage cavity 31 can more easily reach all parts of the storage cavity, thereby improving the cleaning efficiency of the storage cavity, reducing cleaning dead spots, and thus making the cleaning of the storage component 30 simpler and the cleaning effect of the storage component 30 better.

[0132] Please see Figure 8 Fifthly, embodiments of this application also provide a cleaning system 10000, which includes a base station 3000 and the cleaning device 1000 described in the above embodiments.

[0133] 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 can clean the mop attachments of the cleaning equipment 1000 and can also charge the cleaning equipment 1000. 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 mop attachments of the cleaning equipment 1000 are dirty and / or the power is insufficient, the cleaning equipment 1000 returns to the base station 3000 to clean the mop attachments and / or recharge. When the mop attachments of the cleaning equipment 1000 are cleaned and / or fully charged, the cleaning equipment 1000 can leave the base station 3000 and continue cleaning the surface to be cleaned.

[0134] Please combine Figure 3 and Figure 5 In one embodiment, the cleaning system 10000 may include a liquid supply unit. The liquid supply unit may be located at the base station 3000 and is connected to the second opening 15 or the fourth opening 17 when the cleaning device 1000 enters the base station 3000. When the storage unit 30 requires cleaning and is in a first state, the cleaning device 1000 enters the base station 3000, and the liquid supply unit supplies cleaning liquid to the storage cavity 31 through the second opening 15 or the fourth opening 17. The liquid supply unit may include a clean water tank of the cleaning system 10000, which provides cleaning liquid to the storage unit 30 when it is in the first state. The liquid supply unit 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 unit 30 does not require cleaning, the valve is closed, preventing cleaning liquid in the clean water tank of the cleaning system 10000 from flowing into the storage cavity 31 through the second opening 15 or the fourth opening 17. When the storage unit 30 needs to be cleaned and the storage unit 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.

[0135] In the cleaning system 10000 of this application embodiment, the storage component 30 can switch between a first state and a second state, and the volume of the storage cavity 31 when the storage component 30 is in the first state is smaller than the volume of the storage cavity 31 when the storage component 30 is in the second state. When the storage component 30 needs to store dirt, it can be in the second state. When the storage component 30 needs to be cleaned, it can switch to the first state. Because the volume of the storage cavity 31 is smaller in the first state, when cleaning the storage cavity 31, the liquid entering the storage cavity 31 can more easily reach all parts of the storage cavity, thereby improving the cleaning efficiency of the storage cavity, reducing cleaning dead spots, and thus making the cleaning of the storage component 30 simpler and the cleaning effect of the storage component 30 better.

[0136] Please see Figure 1 , Figure 2 and Figure 9 Fourthly, embodiments of this application also provide a cleaning method, which is applied to the recycling component 100, cleaning module, cleaning equipment 1000, and cleaning system 10000 of the above embodiments. The cleaning method includes:

[0137] 01: Extract waste into storage cavity 31;

[0138] 03: Discharge waste into the storage cavity 31; and

[0139] 05: Clean the storage cavity 31.

[0140] Specifically, when the cleaning module is cleaning the surface to be cleaned, the scraper removes the dirt from the mop, and the dirt enters the wastewater tank 70. The controller of the recovery assembly 100 can control the first gas suction unit 40 to start, so that the dirt in the wastewater tank 70 is sucked into the storage unit 30. The dirt passes through the connecting pipe 90 and enters the storage cavity 31 from the first outlet and is stored in the storage cavity 31.

[0141] When the storage cavity 31 is full of dirt or the cleaning robot has finished cleaning the surface to be cleaned, the cleaning robot enters the base station 3000 or moves to the designated drainage position, and the controller controls the discharge of dirt from the storage cavity 31 to the outside of the storage unit 30. The dirt in the storage cavity 31 flows out of the storage cavity 31 from the first outlet or the third outlet, passes through the connecting pipe 90 and the sewage tank 70, and is discharged from the drain port 81.

[0142] When waste is discharged from the storage chamber 31, the controller activates the liquid supply unit 50, allowing external liquid to enter the storage chamber 31 to flush it. The liquid flows through various locations on the inner wall of the storage unit 30, carrying away the waste from the inner wall of the storage unit 30, and flows out of the storage chamber 31 through the first or third outlet. The waste passes through the connecting pipe 90 and the wastewater tank 70, and is discharged from the drain port 81.

[0143] Please see Figure 3 , Figure 4 and Figure 10 In some embodiments, 01: drawing waste into storage cavity 31 includes:

[0144] 011: The gas in the containing space 13 is extracted to reduce the gas pressure in the containing space 13, so that the storage device 30 switches from the first state to the second state; and

[0145] 013: Extract gas from storage chamber 31 to reduce the gas pressure in storage chamber 31, so that dirt can enter and remain in storage chamber 31.

[0146] Specifically, the controller activates the third gas suction unit 60, which extracts gas from the containing space 13 through the fifth outlet, reducing the gas pressure in the containing space 13 to be lower than the gas pressure in the storage cavity 31. This causes the elastic storage unit 30 to expand, switching it from a first state to a second state. In the second state, the storage cavity 31 has a larger volume and is used to store waste.

[0147] After the storage unit 30 switches from the first state to the second state, the third gas suction unit 60 continues to operate, and the controller controls the first gas suction unit 40 to start. The first gas suction unit 40 extracts gas from the storage cavity 31 through the second opening 15, so that the gas pressure inside the storage cavity 31 is lower than the external gas pressure and higher than the gas pressure in the current containing space 13. In this way, the storage unit 30 can be stably in the second state, and the dirt in the sewage tank 70 can be squeezed into the storage cavity 31. The first gas suction unit 40 continues to operate to ensure that the dirt can be stored in the storage cavity 31, preventing the dirt from flowing from the storage cavity 31 to the surface to be cleaned.

[0148] Please see Figure 3 , Figure 4 ,and Figures 11 to 13 In some embodiments, 03: discharging waste to the outside of the storage cavity 31 includes:

[0149] 031: Pumping air into the receiving space 13 to increase the air pressure in the receiving space 13, so that the contaminant is discharged from the storage cavity 31; and / or

[0150] 033: Pump air into storage chamber 31 to increase the air pressure in storage chamber 31 so that dirt is discharged from storage chamber 31.

[0151] Specifically, please refer to Figure 3 , Figure 4 and Figure 11In one embodiment, when contaminants need to be discharged from the storage cavity 31 to the outside of the storage member 30, air is pumped into the receiving space 13 to increase the air pressure in the receiving space 13, thereby causing the contaminants to be discharged from the storage cavity 31. In one example, the controller controls the third gas suction member 60 to pump air into the receiving space 13 through the fifth opening 18, so that the air pressure in the receiving space 13 is greater than the air pressure in the storage cavity 31. Thus, the elastic storage member 30 is compressed and shrinks, and the storage member 30 switches from the second state to the first state. During the process of the storage member 30 switching from the second state to the first state, the volume of the storage cavity 31 gradually decreases, so that the contaminants in the storage cavity 31 are discharged to the outside of the storage member 30 through the first opening 14 or the third opening. In another example, the controller controls the fourth gas suction member to pump air into the receiving space 13 through the fifth opening 18, so that the air pressure in the receiving space 13 is greater than the air pressure in the storage cavity 31. Storage unit 30 switches from the second state to the first state, the volume of storage cavity 31 gradually decreases, and contaminants in storage cavity 31 are discharged out of storage unit 30 through the first opening 14 or the third opening. In another example, the controller controls the fourth gas suction unit to pump air into the receiving space 13 through the sixth opening, so that the gas pressure in the receiving space 13 is greater than the gas pressure in storage cavity 31. Storage unit 30 switches from the second state to the first state, the volume of storage cavity 31 gradually decreases, and contaminants in storage cavity 31 are discharged out of storage unit 30 through the first opening 14 or the third opening.

[0152] At this point, the controller only needs to activate either the third gas suction component 60 or the fourth gas suction component to operate, making the controller's operation relatively simple. Furthermore, the recovery assembly 100 has fewer components operating simultaneously, resulting in lower power consumption.

[0153] Please see Figure 3 , Figure 4 and Figure 12In another embodiment, when waste needs to be discharged from the storage cavity 31 to the outside of the storage unit 30, air is pumped into the storage cavity 31 to increase the air pressure inside the storage cavity 31, so that the waste is discharged from the storage cavity 31. In one example, the controller of the recovery assembly 100 controls the first gas suction member 40 to pump air into the storage cavity 31 through the second opening 15, so that the air pressure inside the storage cavity 31 is greater than the external air pressure. At this time, the storage unit 30 is still in the second state. When the air pressure inside the storage cavity 31 is greater than the external air pressure, the waste in the storage cavity 31 will be discharged to the outside of the storage unit 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 to pump air into the receiving space 13 through the second opening 15, so that the air pressure inside the storage cavity 31 is greater than the external air pressure. At this time, the storage unit 30 is still in the second state. When the air pressure inside the storage cavity 31 is greater than the external air pressure, the waste in the storage cavity 31 will be discharged to the outside of the storage unit 30 through the first opening 14 or the third opening.

[0154] At this point, the contaminants in storage chamber 31 can be almost completely discharged, leaving minimal contaminants. Furthermore, the controller of the recovery assembly 100 only needs to activate either the first gas suction unit 40 or the second gas suction unit to operate, making the controller's operation relatively simple. The recovery assembly 100 has fewer components operating simultaneously, resulting in lower power consumption.

[0155] Please see Figure 3 , Figure 4 and Figure 13In another embodiment, when waste needs to be discharged from the storage cavity 31 to the outside of the storage unit 30, air is pumped into the receiving space 13 to increase the air pressure in the receiving space 13, and simultaneously air is pumped into the storage cavity 31 to increase the air pressure in the storage cavity 31, so that the waste can be discharged from the storage cavity 31. In one example, the controller controls the first gas suction member 40 and the third gas suction member 60 to start simultaneously. During the process of the storage unit 30 switching from the second state to the first state under the action of the third gas suction member 60, the first gas suction member 40 pumps air into the storage cavity 31, so that the waste in the storage cavity 31 can be quickly discharged to the outside of the storage unit 30. In another example, the controller controls the first gas suction member 40 and the fourth gas suction member to start simultaneously. During the process of the storage unit 30 switching from the second state to the first state under the action of the fourth gas suction member, the first gas suction member 40 pumps air into the storage cavity 31, so that the waste in the storage cavity 31 can be quickly discharged to the outside of the storage unit 30. In another example, the controller activates the second and third gas suction components 60 simultaneously. During the transition from a second state to a first state under the action of the third gas suction component 60, the second gas suction component pumps air into the storage cavity 31, allowing contaminants in the storage cavity 31 to be quickly discharged out of the storage unit 30. In yet another example, the controller activates the second and fourth gas suction components simultaneously. During the transition from a second state to a first state under the action of the fourth gas suction component, the second gas suction component pumps air into the storage cavity 31, allowing contaminants in the storage cavity 31 to be quickly discharged out of the storage unit 30.

[0156] At this time, with the air pump corresponding to the storage cavity 31 and the air pump corresponding to the receiving space 13 working simultaneously, the dirt in the storage cavity 31 can be quickly discharged to the outside of the storage unit 30, and the efficiency of dirt discharge from the storage cavity 31 is high. Moreover, the dirt in the storage cavity 31 can be almost completely discharged from the storage cavity 31, and there is less dirt remaining in the storage cavity 31.

[0157] Please see Figure 3 , Figure 4 and Figure 14 In some embodiments, 05: Cleaning the storage cavity 31 includes:

[0158] 051: When dirt is discharged from the storage cavity 31, a cleaning liquid is supplied to the storage cavity 31 to clean the storage cavity 31.

[0159] When the contaminant is discharged from the storage chamber 31 and the storage unit 30 is in the first state, the controller controls the liquid supply unit to provide cleaning liquid to the storage unit 30. The cleaning liquid enters the storage chamber 31 and cleans the storage chamber 31.

[0160] In one embodiment, the liquid supply unit may be equipped with a water pump. When the storage unit 30 needs cleaning, the controller controls the water pump to start, allowing cleaning liquid in the liquid supply unit to flow into the storage cavity 31. The cleaning liquid flows into various locations on the inner wall of the storage unit 30, carrying away contaminants from the inner wall of the storage unit 30 and flowing them out of the storage unit 30, thus achieving a better cleaning effect. In one example, the liquid supply unit is connected to the second opening 15. After the controller starts the water pump, the cleaning liquid enters the storage cavity 31 through the second opening 15 and cleans the storage cavity 31. In another example, the liquid supply unit is connected to the fourth opening 17. After the controller starts the water pump, the cleaning liquid enters the storage cavity 31 through the fourth opening 17 and cleans the storage cavity 31.

[0161] In another embodiment, the liquid supply unit may include a valve. When the storage unit 30 needs cleaning, the controller controls the valve to open, allowing cleaning liquid in the liquid supply unit to flow into the storage cavity 31. The cleaning liquid flows to various locations on the inner wall of the storage unit 30, carrying away contaminants from the inner wall of the storage unit 30 and flowing them out of the storage unit 30, thus achieving a better cleaning effect. In one example, the liquid supply unit is connected to the second opening 15. After the controller controls the valve to open, the cleaning liquid enters the storage cavity 31 through the second opening 15 and cleans the storage cavity 31. In another example, the liquid supply unit is connected to the fourth opening 17. The controller controls the valve to open, allowing the cleaning liquid to enter the storage cavity 31 through the fourth opening 17 and clean the storage cavity 31.

[0162] In the cleaning method of this application embodiment, the storage device 30 can switch between a first state and a second state, and the volume of the storage cavity 31 when the storage device 30 is in the first state is smaller than the volume of the storage cavity 31 when the storage device 30 is in the second state. When the storage device 30 needs to store dirt, it can be in the second state. When the storage device 30 needs to be cleaned, it can switch to the first state. Because the volume of the storage cavity 31 is smaller in the first state, when cleaning the storage cavity 31, the liquid entering the storage cavity 31 can more easily reach all positions within the storage cavity, thereby improving the cleaning efficiency within the storage cavity, reducing cleaning dead zones, and thus simplifying the cleaning of the storage device 30 and achieving a better cleaning effect.
