[0042] Example 1

[0043] like Figures 1 to 2 As shown, this embodiment provides a container 10, including a container body 100 and a separation mechanism 200 disposed in the container body 100. The container body 100 can collect and store dry waste and wet waste simultaneously, and the separation mechanism 200 can separate the dry waste and wet waste; and the drain port 105 at the bottom of the container body 100 is connected to an external first negative pressure generating device. The negative pressure generated by the first negative pressure generating device can act on the receiving cavity, so that the airflow in the receiving cavity drives the liquid to rotate along the inner wall of the receiving cavity multiple times before being discharged through the drain port 105, thereby achieving efficient self-cleaning.

[0044] Specifically, the container body 100 may include a container body with a receiving groove 102 on the top. The receiving groove 102 on the top of the container body of the container 10 can be used to accommodate the second negative pressure generating device. Moreover, the container body has a circular receiving cavity inside, and a partition 130 is provided inside the container body. The partition 130 divides the receiving cavity into a liquid collection cavity 106 and a gas separation cavity 108. The top of the container body has a sludge inlet 104 communicating with the liquid collection cavity 106, and the sludge inlet 104 is located in the tangential direction of the circular receiving cavity.

[0045] Furthermore, the bottom of the container body is provided with a drain port 105, which is connected to the liquid collection chamber 106 and used to connect to an external first negative pressure generating device. Through the drain port 105, the negative pressure generated by the first negative pressure generating device can be applied to the receiving chamber through the drain port 105, causing the airflow in the receiving chamber to drive the liquid to rotate multiple times along the inner wall of the receiving chamber before being discharged through the drain port 105, thus achieving efficient self-cleaning of the container 10.

[0046] Furthermore, the separation mechanism 200 may include a first separation structure 210 and a second separation structure 220 connecting the partition 130 and / or the container body; that is, both the first separation structure 210 and the second separation structure 220 may be disposed on at least one of the partition 130 and the container body. Moreover, the first separation structure 210 connects the liquid collection chamber 106 and the gas separation chamber 108, and the second separation structure 220 connects the gas separation chamber 108 and the receiving groove 102. Furthermore, the first separation structure 210 and the second separation structure 220 are staggered along the height direction of the container body to prevent blockage when they are disposed together, which would affect the suction of gas and waste.

[0047] The second negative pressure generating device can not only draw dry and wet waste from the external environment into the container's receiving cavity through the suction port 104 on the container body, but also draw the gas in the receiving cavity into the outside atmosphere, achieving simultaneous collection of dry and wet waste. Furthermore, through the first separation structure 210 and the second separation structure 220 provided in the container body 100, when dry and wet waste are drawn into the receiving cavity, the first separation structure 210 collects the dry and wet waste into the liquid collection cavity 106 separated by the partition 130, and the gas in the dry and wet waste enters the gas separation cavity 108 separated by the partition 130 through the first separation structure 210, and is then separated by the second separation structure 220 before being output to the receiving groove 102 (i.e., the outside atmosphere). In this way, dry and wet waste can be collected and stored simultaneously, improving cleaning efficiency and enhancing the cleaning effect.

[0048] Furthermore, such as Figures 3 to 5As shown, the container body may include a sleeved cylindrical outer container shell 110 and a cylindrical inner container shell 120. The outer cylindrical shape of the outer container shell 110 can be a closed annular structure such as circular, elliptical, or square, while its inner cylindrical shape is circular. The inner container shell 120 is also circular, with the tops of the outer container shell 110 and the inner container shell 120 being closedly connected. The bottom of the outer container shell 110 is also closed, while the bottom of the inner container shell 120 is open. The top of the inner container shell 120 is recessed inward, forming a receiving groove 102 on its top. Furthermore, a circular receiving cavity is formed between the outer container shell 110 and the inner container shell 120, and the bottom of the inner container shell 120 is open, allowing the receiving cavity to communicate with the receiving groove 102 through the open bottom of the inner container shell 120. Furthermore, there can be a height difference between the bottom end of the inner container shell 120 and the bottom end of the outer container shell 110, forming a receiving cavity (the bottom part of the receiving cavity) at the bottom end of the outer container shell 110, which facilitates the accumulation and storage of dry and wet waste. In this case, the receiving cavity of the container body is a circular cavity with a U-shaped cross-section. Alternatively, the bottom end of the inner container shell 120 can be directly connected to the bottom end of the outer container shell 110, making the receiving cavity inside the container body an annular cavity.

[0049] Furthermore, the outer container shell 110 may include an outer shell body 112 with open ends, and an outer shell bottom cover 114 covering the bottom end of the outer shell body 112. The outer shell bottom cover 114 forms the aforementioned receiving cavity. An annular receiving main cavity is formed between the outer shell body 112 and the inner container shell 120. The receiving main cavity communicates with the receiving bottom cavity to form a receiving cavity. Moreover, the top end of the outer shell body 112 and the top end of the inner container shell 120 can be connected as one piece, while the outer shell body 112 and the outer shell bottom cover 114 can be detachably connected, which facilitates the processing and manufacturing of the container body, the setting of the partition 130, and the installation of the first separation structure 210 and the second separation structure 220.

[0050] Furthermore, the partition 130 can be a cylindrical plate with a closed bottom, and the top of the cylindrical plate is connected to the inner wall surface of the top of the inner container shell 120. That is, by setting the cylindrical partition 130 in the receiving cavity of the container body, the outer container shell 110, the partition 130 and the inner container shell 120 are sequentially nested, separating the outer container shell 110 and the inner container shell 120 from the inside, thereby dividing the receiving cavity into annular liquid collection chamber 106 and annular gas separation chamber 108 located on the inner and outer sides. In addition, the partition 130 can be a cylindrical plate with open ends, and the top of the cylindrical partition 130 can be connected to the inner wall surface of the top of the inner container shell 120, while the bottom of the partition 130 is connected to the inner wall surface of the bottom of the outer container shell 110.

[0051] Alternatively, the partition 130 can be flat and longitudinally separated between the outer container shell 110 and the inner container shell 120, dividing the containment cavity into a liquid collection cavity 106 and a gas separation cavity 108 located on the left and right sides (or the front and rear sides). Alternatively, the flat partition 130 can be transversely separated between the outer container shell 110 and the inner container shell 120, dividing the containment cavity into a gas separation cavity 108 and a liquid collection cavity 106 located on the upper and lower sides.

[0052] Furthermore, the first separation structure 210 can be disposed on the partition 130, between the partition 130 and the inner container shell 120, or between the partition 130 and the outer container shell 110, to connect the gas separation chamber 108 and the liquid collection chamber 106. Moreover, the second separation structure 220 can be disposed between the partition 130 and the inner container shell 120 to connect the gas separation chamber 108 to the outside atmosphere. Furthermore, the first separation structure 210 and the second separation structure 220 are staggered to avoid interference between them and thus prevent them from affecting the separation effect of waste and gas.

[0053] In this embodiment, the first separation structure 210 can be disposed at the top of the cylindrical partition 130, located between the top of the partition 130 and the inner wall surface of the top of the inner container shell 120. By disposing the first separation structure 210 at a high position, liquid in wet waste can be prevented or reduced from entering the gas separation chamber 108 through the first separation structure 210. Alternatively, the first separation structure 210 can be disposed in the middle of the cylindrical partition 130, or between the middle of the partition 130 and the middle of the outer container shell 110 (or the middle of the inner container shell 120), or between the top of the partition 130 and the top of the outer container shell 110.

[0054] Furthermore, the first separation structure 210 may include a separation mesh 212 disposed on the top of the partition 130, between the top of the partition 130 and the inner wall surface of the top of the inner container shell 120. The separation mesh 212 is a fine-mesh filter screen, which can intercept and separate dry and wet waste that is sucked into the liquid collection chamber 106 through the waste inlet, so as to prevent them from entering the gas separation chamber 108. Moreover, the separation mesh 212 may be designed as an annular shape to correspond to the shape of the cylindrical partition 130; in addition, the separation mesh 212 may also be designed as an arc shape, or as a straight shape, etc.

[0055] Furthermore, the top of the partition 130 is provided with a water-proof duct connecting the liquid collection chamber 106 and the gas separation chamber 108, and the separation net 212 can be enclosed on the outside of the water-proof duct. The water-proof duct can intercept the liquid in the liquid collection chamber 106 and also facilitates the installation of the separation net 212. In this embodiment, the water-proof duct can be configured as a ring, surrounding the top of the partition 130. Moreover, the separation net 212 is sealed on the outside of the water-proof duct, and the inside of the water-proof duct has a connecting opening to communicate with the gas separation chamber 108.

[0056] Furthermore, in this embodiment, the second separation structure 220 can be closed at the bottom opening of the inner container shell 120, and the second separation structure 220 is located between the bottom end of the inner container shell 120 and the bottom end of the cylindrical partition 130, separating the gas separation chamber 108 from the outside atmosphere. It can separate the gas entering the outside atmosphere through the gas separation chamber 108, and further filter out liquids and particulate matter in the gas. In addition, the second separation structure 220 can also be located between the middle (or top) of the inner container shell 120 and the middle (or top) of the partition 130.

[0057] Furthermore, the second separation structure 220 may include a HEPA separation structure 222 closed between the bottom end of the partition 130 and the bottom end of the inner container shell 120. This allows the gas in the gas separation chamber 108 to be separated by the HEPA separation structure 222 before being delivered to the outside atmosphere (accommodating groove 102). The HEPA separation structure 222 may also be annular to facilitate its placement between the partition 130 and the inner container shell 120. Alternatively, the HEPA separation structure 222 may be a block structure, directly sealed at the bottom opening of the inner container shell 120.

[0058] Furthermore, the container body 100 includes a drain valve 140 movably disposed at the drain outlet 105, which is used to open or close the drain outlet 105. When collecting waste through the liquid collection chamber 106, the drain valve 140 can be used to close the drain outlet 105 to facilitate the storage of dry and wet waste in the liquid collection chamber 106. When the dry and wet waste in the liquid collection chamber 106 reaches a certain amount, the drain valve 140 at the drain outlet 105 can be opened, allowing the drain outlet 105 to open (i.e., the drain outlet 105 connects to the outside and the liquid collection chamber 106), so that the dry and wet waste in the liquid collection chamber 106 can be discharged outside the container 10. Moreover, the drain valve 140 can be hinged to the bottom of the outer container shell 110 of the container body 100, making it easy to rotate the drain valve 140 to lock it tightly closed or to open the drain outlet 105.

[0059] In addition, such as Figures 2 to 5As shown, the container body is provided with an inner cavity cleaning structure 300, which is correspondingly arranged with the inner wall surface of the liquid collection chamber 106. The liquid collection chamber 106 of the container 10 is used to collect and store dry and wet waste. After the collected and stored dry and wet waste is discharged through the drain port 105, there may be waste residue on the inner wall surface (including the side wall and bottom wall) of the liquid collection chamber 106. At this time, the inner wall surface of the liquid collection chamber 106 can be cleaned by the inner cavity cleaning structure 300, and the dry and wet waste remaining in the liquid collection chamber 106 can be cleaned.

[0060] Furthermore, the internal cleaning structure 300 may include multiple cleaning holes 310 arranged on the top of the container body. Each cleaning hole 310 communicates with the liquid collection chamber 106 and is correspondingly arranged to the inner wall of the liquid collection chamber 106. Cleaning fluid can be sprayed into the liquid collection chamber 106 through the cleaning holes 310 on the top of the container body. A negative pressure is generated by the first negative pressure generator on the external base station and acts on the drain port 105, causing the cleaning fluid in the liquid collection chamber 106 to rotate and clean along the inner wall, and discharging the cleaned debris from the drain port 105, achieving efficient self-cleaning. Moreover, the multiple cleaning holes 310 are also arranged in a ring shape along the top of the container body, corresponding to the annular liquid collection chamber 106, resulting in more uniform and thorough cleaning.

[0061] Furthermore, the inner cavity cleaning structure 300 may include an annular cleaning pipe located at the top of the container body, and a liquid inlet 340 located at the top of the container body. The liquid inlet 340 is connected to the cleaning pipe, and each cleaning hole 310 is also connected to the cleaning pipe. Cleaning fluid can be delivered to the cleaning pipe through the liquid inlet 340, and then delivered to multiple cleaning holes 310 through the cleaning pipe. Simultaneously, the cleaning fluid is sprayed into the liquid collection chamber 106 through the multiple cleaning holes 310. In this way, cleaning fluid can be delivered to multiple cleaning holes 310 simultaneously through a single cleaning pipe, which is simple and efficient.

[0062] Furthermore, the cleaning pipe may be provided with one or more, and correspondingly, the multiple cleaning holes 310 may be distributed in one or more rings.

[0063] Furthermore, the top of the container body is provided with an annular liquid passage 320, and the top of the container body is provided with a cover plate 330, which is closed and covered on the liquid passage 320 to seal the liquid passage 320 as a cleaning channel. By opening an annular liquid passage 320 on the top of the container body, and covering the liquid passage 320 with the cover plate 330, a closed annular cleaning channel is formed, corresponding to the annular liquid collection chamber 106. Moreover, the cross-section of the liquid passage 320 can be triangular, rectangular, trapezoidal, etc. Furthermore, the cover plate 330 can also be annular, corresponding to the shape of the liquid passage 320, to facilitate sealing it. In addition, a liquid inlet 340 can be provided on the cover plate 330 and communicate with the liquid passage 320. Cleaning fluid can be delivered into the liquid passage 320 through the liquid inlet 340.

[0064] Compared to traditional wastewater tanks, the container 10 proposed in this invention achieves efficient self-cleaning while maintaining high dust collection efficiency and saving water consumption. Experiments show that when standard ash, mung beans, rice, millet, cat litter, and other dry waste, as well as mixtures of various wet wastes, are placed inside the container, the self-cleaning process achieves an emptying rate of 99% to 100%, with almost no residue remaining inside. This avoids frequent manual cleaning of the wastewater tank and the problem of foul odors caused by users failing to clean the tank in a timely manner.

[0065] In addition, the container 10 in this embodiment may be a box structure, a container structure, or other similar cavity structure for collecting dry and wet waste.

[0066] Example 2

[0067] This embodiment provides a cleaning device, including a device body, a container 10 disposed on the device body, and a second negative pressure generating device disposed on the device body and located in the receiving groove 102 of the container 10.

[0068] When the cleaning equipment is working, the drain valve 140 at the bottom of container 10 closes the drain port 105. Under the action of the second negative pressure generating device, the suction airflow carrying sewage (wet waste) and dry waste can be drawn into the liquid collection chamber 106 of container 10 from the suction port 104 at the top of container 10. Sewage, waste and suction airflow are separated. The suction airflow is drawn into the gas separation chamber 108 through the first separation structure 210 (pore-filled separation mesh 212), and then separated by the radially ventilated second separation structure (annular HEPA separation structure 222). After exiting the airflow, the wastewater and garbage enter the receiving groove 102 and fall into the wastewater storage space (receiving bottom cavity) below the liquid collection chamber 106. When self-cleaning is required, the drain valve 140 opens the drain port 105, and the first negative pressure generating device generates negative pressure to act on the drain port 105. At the same time, the cleaning hole 310 provided on the top of the container body sprays cleaning liquid into the liquid collection chamber 106. At this time, the cleaning liquid makes a circular motion in the liquid collection chamber 106 to clean the wall surface, and the cleaned wastewater is discharged from the drain port 105.

[0069] In this embodiment, the cleaning equipment can be a sweeping robot or a mopping robot with mopping function. Furthermore, the second negative pressure generating device can be a fan or other negative pressure generating mechanism.

[0070] Example 3

[0071] This embodiment provides a cleaning system, including cleaning equipment and a cleaning base station used in conjunction with the cleaning equipment. The cleaning base station includes a cleaning infusion system and a sewage extraction system, the sewage extraction system including a first negative pressure generating device.

[0072] After the cleaning equipment returns to the cleaning base station after completing its cleaning work, the cleaning base station delivers cleaning fluid to the annular cleaning pipe at the top of the cleaning equipment's container through a cleaning fluid delivery system corresponding to the cleaning equipment's inlet 340. The fluid is then sprayed into the liquid collection chamber 106 of the container 10 through multiple cleaning holes 310 connected to the cleaning pipe. When the drain valve 140 of the container 10 is open, the cleaning base station's suction system can draw dry and wet waste and wastewater from the liquid collection chamber 106 of the container 10 through the drain port 105. Furthermore, the cleaning fluid from the cleaning base station is sprayed onto the inner wall of the liquid collection chamber 106 of the container 10. While the suction system draws out the waste and debris from the container 10, it generates an air vortex in the circular liquid collection chamber 16, causing the cleaning fluid to rotate and continuously flush the inner wall (including the side and bottom walls) of the liquid collection chamber 106. The wastewater containing various dry and wet waste is then drawn from the drain port at the bottom of the container 10 into the cleaning base station.

[0073] The cleaning equipment provided in this embodiment has good dust collection efficiency, good self-cleaning effect, and saves water consumption for cleaning base stations, thus providing users with a better experience.

[0074] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
