[0036] Please refer to 1 to Figure 3 One embodiment of this application provides a wastewater tank 100 for installation on a base station 200 of a cleaning device (not shown in the figure). The wastewater tank 100 includes a tank body 110 and a filter element 120. A receiving cavity 111 and a wastewater inlet 112 communicating with the receiving cavity 111 are formed within the tank body 110. The receiving cavity 111 is used to store wastewater. The filter element 120 is disposed within the tank body 110 and communicates with the receiving cavity 111. The filter element 120 is used to filter impurities in the wastewater to obtain reusable filtered water.

[0037] The wastewater tank 100 of this application uses a filter element 120 to filter wastewater to obtain reusable filtered water. The filtered water can be transported through a pipeline to the cleaning tray (not shown in the figure) of the base station 200 for cleaning operations of the cleaning tray, or transported to the water tank of the cleaning equipment as cleaning water for the cleaning equipment. The wastewater in the cleaning tray can be drawn through a pipeline into the receiving cavity 111 for filtration, thereby realizing the recycling of wastewater filtration.

[0038] This application employs a wastewater filtration and recycling method. On one hand, the wastewater in the wastewater tank 100 can be filtered and recycled, preventing the tank from filling too quickly and reducing the frequency of user cleaning. On the other hand, since the base station 200 also has a clean water tank 210, the consumption of clean water can be reduced, thereby reducing the frequency of users adding water to the clean water tank 210, ultimately lowering the overall frequency of user maintenance of the base station 200 and improving the user experience. Furthermore, because this application uses a wastewater filtration and recycling method, under the same base station maintenance frequency, the overall size of the wastewater tank 100 and the base station 200 can be reduced, achieving miniaturization of the base station 200 and meeting the usage needs of different households.

[0039] In some specific embodiments, the base station 200 can be equipped with both a clean water tank 210 and a wastewater tank 100. When there is not enough reusable filtered water in the wastewater tank 100, the clean water tank 210 provides clean water to the water tanks of the cleaning tray and the cleaning equipment. The wastewater generated after the cleaning operation of the cleaning tray is drawn into the wastewater tank 100 and filtered through the filter element 120 to produce filtered water. The filtered water can be used first when using water in the future. When the filtered water is insufficient, the clean water tank 210 replenishes the clean water, so as to realize the wastewater filtration and recycling and meet the usage needs of the base station 200 and the cleaning equipment.

[0040] In some other specific embodiments, since the wastewater tank 100 in this application can deliver filtered water to the cleaning tray and water tank of the cleaning equipment in the base station 200, the clean water tank 210 can also be omitted from the base station 200. During use, the user can add a certain amount of clean water to the wastewater tank 100, and subsequently achieve water recycling through filtration. This method eliminates the clean water tank 210, providing space for other components in the base station 200 or allowing for an overall reduction in the size of the base station 200, thus meeting different usage requirements.

[0041] In some embodiments, the wastewater tank 100 includes a suction pipe assembly that draws wastewater from the cleaning tray of the base station 200 into the receiving cavity 111, achieving wastewater recycling. The suction pipe assembly includes a suction pipe (not shown) and a vacuum pump 1251. One end of the suction pipe is connected to the inlet 112 of the receiving cavity 111, and the other end is connected to the cleaning tray of the base station 200. The vacuum pump 1251 can be located at the inlet 112. By creating negative pressure through the vacuum pump 1251, wastewater on the cleaning tray can be drawn into the receiving cavity 111 through the suction pipe, preventing wastewater from overflowing from the cleaning tray and ensuring that the cleaning tray remains clean and hygienic after use.

[0042] In this application, wastewater is filtered using filter element 120, thereby achieving wastewater recycling. This application proposes several specific structures for filter element 120, which are described below with reference to embodiments:

[0043] In some embodiments, the filter element 120 includes a partition plate 121. The partition plate 121 divides the accommodating cavity 111 to form a first water storage cavity 1111 and a second water storage cavity 1112. The first water storage cavity 1111 communicates with the sewage inlet 112 and is used to store sewage. At least one water passage hole 1211 is provided on the partition plate 121, and the water passage hole 1211 is higher than the bottom of the first water storage cavity 1111.

[0044] The first water storage chamber 1111 is used to store sewage, which undergoes preliminary filtration within it. Impurities with a density greater than water in the sewage settle to the bottom of the first water storage chamber 1111. After the water level in the first water storage chamber 1111 rises above the water passage 1211, the clarified filtered water rises above the water passage 1211 and enters the second water storage chamber 1112. The second water storage chamber 1112 stores reusable filtered water. The filtered water can also undergo secondary sedimentation within the second water storage chamber 1112 to further improve its cleanliness. The filtered water in the second water storage chamber 1112 can be piped to the cleaning tray of the base station 200 for cleaning operations, or it can be piped to the water tank of the cleaning equipment as cleaning water for the equipment.

[0045] By setting an isolation plate 121, the accommodating cavity 111 is divided into a first water storage cavity 1111 and a second water storage cavity 1112. A water passage hole 1211, higher than the bottom of the first water storage cavity 1111, connects the first water storage cavity 1111 and the second water storage cavity 1112. This allows sewage to settle naturally in the first water storage cavity 1111, with denser impurities settling at the bottom. The clarified filtered water can then flow smoothly through the water passage hole 1211 into the second water storage cavity 1112, separating from the impurities and improving its cleanliness. The filtered water stored in the second water storage cavity 1112 is of higher quality and more suitable for subsequent cleaning operations or as water for cleaning equipment. The filter element 120 in this embodiment has a simple structure, does not consume additional energy, occupies little space, simplifies the sewage treatment process, and improves the efficiency of sewage treatment, making the entire sewage tank 100 and base station 200 more practical and efficient.

[0046] In addition to impurities with higher density, the wastewater in the first water storage chamber 1111 may also contain impurities with a density less than water, which can be further removed. Furthermore, the filter element 120 also includes a baffle plate 122. The baffle plate 122 is fastened to the side of the partition plate 121 facing the first water storage chamber 1111. One end of the baffle plate 122 is positioned above the water passage hole 1211, and the other end bends and extends towards the bottom of the first water storage chamber 1111. The baffle plate 122 and the partition plate 121 enclose a filtration space 1221, which communicates with the water passage hole 1211. A water suction hole 1222 is formed at the bottom of the baffle plate 122, lower than the water passage hole 1211.

[0047] When wastewater enters the first water storage chamber 1111, impurities with a density less than water, such as grease and foam, may float on the surface or remain suspended in the water. The baffle plate 122, forming a straw-like structure, is embedded in the wastewater stored within the first water storage chamber 1111. By setting up the baffle plate 122, these floating objects are effectively blocked outside the filtration space 1221, preventing them from entering the second water storage chamber 1112 through the water passage 1211. Simultaneously, the suction hole 1222 formed at the bottom of the baffle plate 122 is lower than the water passage 1211, allowing the baffle plate 122 to sink into the wastewater, allowing intermediate clarified filtration water to pass through, thus improving the cleanliness of the filtered water entering the second water storage chamber 1112.

[0048] In this embodiment of the application, by setting up a partition plate 121 and a dirt baffle plate 122 together, impurities with a density greater than or less than that of water in the sewage can be filtered out, while the clarified filtered water is allowed to enter the second water storage chamber 1112 for reuse.

[0049] The height of the water passage 1211 is between one-tenth and nine-tenths of the height of the first water storage chamber 1111. This design ensures that the water passage 1211 is not too close to the bottom, resulting in poor sedimentation of impurities and reducing or preventing sedimented impurities from entering the second water storage chamber 1112, and also preventing the water passage 1211 from being blocked by sediment. The water passage 1211 is also not too high, thereby improving the efficiency of the clarified filtered water entering the second water storage chamber 1112. By setting the water passage 1211 within the above-mentioned height range, the wastewater tank 100 can more efficiently separate clarified filtered water while reducing the frequency of maintenance and cleaning.

[0050] Specifically, the height of the water passage 1211 is one-tenth, one-third, one-half, two-thirds, or nine-tenths of the height of the first water storage chamber 1111, etc., which will not be listed here.

[0051] Please see Figure 4 and Figure 5 To improve the filtration effect, in some embodiments, the filter element 120 further includes a filter module 123. The filter module 123 is disposed within the second water storage chamber 1112. The filter module 123 has an inlet 1231 and an outlet 1232. The inlet 1231 communicates with the second water storage chamber 1112, and the outlet 1232 is used to discharge the filtered water for reuse.

[0052] When the water in the second water storage chamber 1112 needs to be discharged for use, the filter module 123 can draw water from the second water storage chamber 1112 through the inlet 1231. The clarified filtered water is further filtered by the filter module 123 and discharged from the outlet 1232 for use, thereby improving the cleanliness of the filtered water entering the reuse stage.

[0053] The height of the inlet 1231 is between one-tenth and nine-tenths of the height of the second water storage chamber 1112. This design ensures that the inlet 1231 is neither too close to the bottom of the second water storage chamber 1112, which could lead to the intake of deposited impurities, nor too high, which would reduce the water absorption efficiency. By setting the inlet 1231 within the above-mentioned height range, the filter module 123 can more efficiently absorb clarified filtered water while reducing the mixing of impurities.

[0054] Specifically, the height of the inlet 1231 can be one-tenth, one-third, one-half, two-thirds, or nine-tenths of the height of the second water storage chamber 1112, etc., which will not be listed here.

[0055] Furthermore, the filter element 120 also includes a water pumping assembly, which includes a water pumping line (not shown), a power pump 1241, and a photoelectric sensor (not shown). The water pumping line is connected to the filtered water and is used to discharge the filtered water to the cleaning tray or cleaning equipment of the base station 200. The power pump 1241 is disposed in the water pumping line. The photoelectric sensor is disposed in the water pumping line and is used to detect the state of the filtered water in the water pumping line.

[0056] When the filter element 120 does not include the filter module 123, the inlet end of the water pumping pipe can be suspended in the second water storage chamber 1112 for direct extraction of filtered water. When the filter element 120 includes the filter module 123, the inlet end of the water pumping pipe is connected to the outlet 1232 of the filter module 123.

[0057] Specifically, one end of the pumping pipe is connected to the filtered water, and the other end is connected to the cleaning tray or cleaning equipment of the base station 200. When the power pump 1241 is started, it can generate sufficient suction to directly draw the reusable filtered water from the second water storage chamber 1112 through the pumping pipe and deliver it to the cleaning tray or cleaning equipment for subsequent cleaning or sanitation operations; or the pumping pipe is connected to the outlet 1232 of the filter module 123, which is used to draw the pre-filtered water into the filter module 123 through the inlet 1231, and after further filtration by the filter module 123, it is discharged from the outlet 1232 for reuse.

[0058] The photoelectric sensor monitors the status of the filtered water in the pumping pipeline. It can detect key parameters such as the light transmittance or water flow rate in real time to ensure that the filtered water delivered to the cleaning tray or cleaning equipment meets the requirements. Once an abnormality such as substandard water quality or insufficient water volume is detected, the sensor will issue an alarm to remind the user to take timely measures such as cleaning the wastewater tank 100, thereby effectively ensuring the cleaning quality and efficiency of the base station 200 and the cleaning equipment.

[0059] In some embodiments, the filter module 123 is detachably installed in the second water storage chamber 1112. On the one hand, when the user cleans and maintains the sewage tank 100, the filter module 123 can be disassembled to facilitate cleaning of the inside of the sewage tank 100; on the other hand, it facilitates the replacement of the filter module 123. The user can regularly check and replace the filter module 123 according to the usage and needs to maintain the best filtration effect.

[0060] The filter module 123 includes at least a filter layer 130 and a sterilization layer 140. The filter layer 130 filters and adsorbs impurities, while the sterilization layer 140 sterilizes and deodorizes. The filter layer 130 typically uses high-efficiency filter materials such as PP cotton, activated carbon, or polymer fibers, which effectively adsorb tiny particles, organic matter, and some dissolved impurities in the water, further improving the cleanliness of the reused filtered water. The sterilization layer 140 may use sterilization particles, such as those containing antibacterial agents like silver ions, hypochlorite, and chitosan. These technologies can kill bacteria, viruses, and other microorganisms in the water, while also removing unpleasant odors, thus providing healthier and safer clean water, improving the cleaning efficiency of the cleaning equipment, and preventing the generation of unpleasant odors.

[0061] In the above embodiments, the filter element 120 uses a partition plate 121 with water passage holes 1211 to achieve filtration through density difference, and can be further combined with the filter module 123 to achieve sufficient filtration. This application also provides some embodiments in which the filter element 120 may not have a partition plate 121, and the filter element 120 draws sewage from the receiving cavity 111 for filtration and discharges it, as follows:

[0062] Please continue reading. Figure 9 In some embodiments, the filter element 120 draws in wastewater from the receiving cavity 111, filters it, and then discharges it. The filter element 120 includes a filter module 123 and a water pumping pipe assembly (not shown in the figure). The structure of the filter module 123 is basically the same as that of the filter module 123 in the above embodiments. The filter module 123 is disposed inside the housing 110 and has an inlet 1231 and an outlet 1232. The inlet 1231 is connected to the receiving cavity 111. The water pumping pipe assembly is connected to the outlet 1232 and is used to draw wastewater into the filter module 123 through the inlet 1231, filter it through the filter module 123, and discharge it through the outlet 1232 for reuse. The water pumping pipe assembly enables wastewater to be effectively guided to the filter module 123 while ensuring that the filtered water can be discharged smoothly.

[0063] The pumping pipe assembly effectively guides wastewater to the filtration module 123 while ensuring the smooth discharge of filtered water. By setting up the filtration module 123, wastewater within the containment chamber 111 can be filtered to obtain reusable filtered water, achieving wastewater recycling. The filter element 120 in this embodiment has a simple structure, consumes no additional energy, occupies little space, simplifies the wastewater treatment process, and improves wastewater treatment efficiency, making the entire wastewater tank 100 and base station 200 system more practical and efficient.

[0064] The height of the inlet 1231 is between one-tenth and nine-tenths of the height of the second water storage chamber 1112. Wastewater can initially settle at the bottom of the receiving chamber 111. This design ensures that the inlet 1231 is neither too close to the bottom of the receiving chamber 111, which could lead to the intake of deposited impurities, nor too high, which would reduce water absorption efficiency. By setting the inlet 1231 within the aforementioned height range, the filter module 123 can more efficiently absorb clarified filtered water while reducing the mixing of impurities.

[0065] Specifically, the height of the inlet 1231 can be one-tenth, one-third, one-half, two-thirds, or nine-tenths of the height of the accommodating cavity 111, etc., which will not be listed here.

[0066] Specifically, the water pumping assembly includes a water pumping pipe (not shown in the figure), a power pump 1241, and a photoelectric sensor (not shown in the figure). The water pumping pipe is connected to the cleaning tray or cleaning equipment of the base station 200, and is also connected to the outlet 1232 of the filter module 123. It is used to pump wastewater into the filter module 123 through the inlet 1231, and after filtration by the filter module 123, the wastewater is discharged from the outlet 1232 for reuse. The power pump 1241 is installed in the water pumping pipe. The photoelectric sensor is installed in the water pumping pipe to detect the state of the filtered water within the water pumping pipe.

[0067] The photoelectric sensor monitors the status of the filtered water in the pumping pipeline. It can detect key parameters such as the light transmittance or water flow rate in real time to ensure that the filtered water delivered to the cleaning tray or cleaning equipment meets the requirements. Once an abnormality such as substandard water quality or insufficient water quantity is detected, the sensor will immediately issue an alarm, reminding the user to take timely measures such as cleaning the wastewater tank 100, thereby effectively ensuring the cleaning quality and efficiency of the base station 200 and the cleaning equipment.

[0068] The filter module 123 includes at least a filter layer 130 and a sterilization layer 140. The filter layer 130 filters and adsorbs impurities, while the sterilization layer 140 sterilizes and deodorizes. The filter layer 130 typically uses high-efficiency filter materials such as PP cotton, activated carbon, or polymer fibers, which effectively adsorb tiny particles, organic matter, and some dissolved impurities in the water, further improving the cleanliness of the reused filtered water. The sterilization layer 140 can use sterilization particles, such as those containing antibacterial agents like silver ions, hypochlorite, and chitosan. These technologies kill bacteria, viruses, and other microorganisms in the water, while also removing unpleasant odors, thus providing healthier and safer clean water, improving the cleaning efficiency of the cleaning equipment, and preventing the generation of unpleasant odors.

[0069] To simplify the structure of the wastewater tank 100, the filter module 123 can be directly installed within the receiving cavity 111. However, in some embodiments, the tank 110 also forms an isolation cavity 113. The isolation cavity 113 is separated from the receiving cavity 111, and the filter module 123 is installed within the isolation cavity 113. The filter element 120 also includes a suction pipe, with its inlet end suspended within the receiving cavity 111 and its outlet end connected to the inlet 1231 of the filter module 123. The filter module 123 is separated from the receiving cavity 111 where wastewater is stored. When the pumping unit is operating, the filter module 123 draws wastewater from the receiving cavity 111 through the suction pipe. The inlet end of the suction pipe being suspended within the receiving cavity 111 prevents the extraction of impurities settled at the bottom of the receiving cavity 111.

[0070] By separately setting the filter module 123 in the isolation chamber 113, the filter module 123 can be separated from the sewage storage chamber 111, thereby avoiding the filter module 123 from being immersed in sewage for a long time. The outer surface of the filter module 123 can be kept clean, making it easy for users to directly take out the filter module 123 for cleaning or replacement, which better meets the user's needs and improves the user experience.

[0071] Please see Figures 6 to 8 The filter module 123 can filter sewage in various ways. This application provides a filter module 123 suitable for sewage tank 100. In some embodiments, the filter module 123 includes a housing 1233 and a support frame 1234. A water inlet channel 1235 and a filter chamber are formed inside the housing 1233. A water inlet 1231 communicating with the water inlet channel 1235 is formed at the bottom of the housing 1233, and the water inlet channel 1235 extends along the height direction of the housing 1233. The support frame 1234 is disposed in the filter chamber and divides the filter chamber into a first chamber 1236 and a second chamber 1237. A filter layer 130 is provided in the first chamber 1236, and the filter layer 130 covers the water inlet channel 1235. A communication port 12371 communicating with the first chamber 1236 is formed at the bottom of the second chamber 1237, and an outlet 1232 is formed at the top of the second chamber 1237. The second compartment 1237 has a sterilization layer 140 between the connecting port 12371 and the water outlet 1232.

[0072] When wastewater flows through the filtration module 123, it passes sequentially through the inlet 1231, the inlet channel 1235, the first chamber 1236, and the second chamber 1237, finally exiting through the outlet 1232. When wastewater enters the first chamber 1236 through the inlet channel 1235, the filter layer 130 covering the inlet channel 1235 filters and adsorbs the wastewater, removing impurities. The filtered water, after passing through the filter layer 130, enters the second chamber 1237 through the connecting port 12371, and after being sterilized and deodorized by the sterilization layer 140 within the second chamber 1237, it exits through the outlet 1232.

[0073] By setting up the water inlet channel 1235, the contact area between the filter layer 130 and the sewage can be effectively increased, improving filtration efficiency and preventing clogging of the filter layer 130. Covering the water inlet channel 1235 with the filter layer 130 can prevent sewage from flowing out directly without being filtered by the filter layer 130. The sterilization layer 140 has an outlet 1232 at the top and a connecting port 12371 at the bottom. Under gravity, the filtered water naturally collects at the connecting port 12371 at the bottom. After being drawn up, it can effectively pass through the sterilization layer 140 for sterilization and deodorization before flowing out from the outlet 1232 at the top, improving the sterilization effect and the overall purification efficiency of the filter module 123.

[0074] Furthermore, the filter module 123 also includes a plurality of first partitions 1238. The first partitions 1238 extend along the height direction of the housing 1233, and are spaced apart on the side of the support frame 1234 facing the filter layer 130, so as to tightly cover the filter layer 130 against the water inlet channel 1235, and form a water passage space between the support frame 1234 and the filter layer 130 for filtered water to pass through. The first partitions 1238 serve to fix and support the filter layer 130, ensuring that the filter layer 130 tightly covers the water inlet channel 1235 and prevents sewage from flowing around it; they also allow a water passage space between the support frame 1234 and the filter layer 130, preventing the support frame 1234 from being too close to the filter layer 130 and affecting the water filtration effect.

[0075] Furthermore, the filter module 123 also includes multiple second partitions 1239. The second partitions 1239 extend along the height of the housing 1233, and are spaced apart in the water inlet channel 1235 to support the filter layer 130 and form a filter grid within the water inlet channel 1235. The second partitions 1239 serve to support the filter layer 130 and also form a filter grid within the water inlet channel 1235, trapping larger impurities outside the water inlet 1231, preventing clogging of the filter module 123, and further ensuring filtration efficiency and effectiveness.

[0076] In some embodiments, multiple first chambers 1236 may be formed around the outer periphery of the second chamber 1237, and multiple water inlet channels 1235 corresponding one-to-one with the first chambers 1236 may be formed within the housing 1233. Each first chamber 1236 may have a filter layer 130 that covers the corresponding water inlet channel 1235. Introducing wastewater into multiple filter layers 130 through multiple water inlet channels 1235 can improve the filtration efficiency of the filter module 123 and reduce the resistance to extracting filtered water.

[0077] Specifically, there may be two first compartments 1236, distributed on both sides of the second compartment 1237. Alternatively, there may be four first compartments 1236, distributed around the second compartment 1237. There may also be one, three, or other numbers of first compartments 1236, depending on the actual situation; no restriction is imposed here.

[0078] Another embodiment of this application provides a base station 200. The base station 200 includes a base station base 230, a base station body 220, and a wastewater tank 100. A cleaning tray (not shown) is provided on the base station base 230. The base station body 220 is disposed on the base station base 230. The wastewater tank 100 is the wastewater tank 100 in any of the above embodiments. The wastewater tank 100 is installed inside the base station body 220, and the wastewater tank 100 absorbs and stores wastewater from the cleaning tray through a suction pipe assembly (not shown).

[0079] Furthermore, the base station 200 also includes a clean water tank 210. The clean water tank 210 is located on the base station body 220. The clean water tank 210 is arranged side by side with the wastewater tank 100.

[0080] The base station 200 of this application uses filter element 120 to filter sewage to obtain reusable filtered water. The filtered water can be transported through pipeline to the cleaning tray of the base station 200 for cleaning operations of the cleaning tray, or transported to the water tank of the cleaning equipment as cleaning water for the cleaning equipment. The sewage in the cleaning tray can be drawn through pipeline into the receiving cavity 111 for filtration, thereby realizing the filtration and recycling of sewage.

[0081] This application employs a wastewater filtration and recycling method. On one hand, the wastewater in the wastewater tank 100 can be filtered and recycled, preventing the tank from filling too quickly and reducing the frequency of user cleaning. On the other hand, since the base station 200 also has a clean water tank 210, the consumption of clean water can be reduced, thereby reducing the frequency of users adding water to the clean water tank 210. This overall reduces the frequency of user maintenance of the base station 200 and improves the user experience. Furthermore, because this application uses a wastewater filtration and recycling method, the overall size of the wastewater tank 100 and the base station 200 can be reduced, enabling the miniaturization of the base station 200 and meeting the usage needs of different households.

[0082] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted. Furthermore, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product of this application is in use.
