[0035] As people pay more and more attention to indoor air quality, floor scrubbers, as cleaning equipment that integrates suction, mopping and washing, have gradually become one of the indispensable household appliances. At the same time, people are increasingly pursuing high-performance floor scrubbers. Base station floor scrubbers solve the problem of frequent changing of clean water and dumping of dirty water.

[0036] At present, there are two main forms of sewage discharge for floor scrubbers in base stations. One is the direct discharge scheme, which opens the valve of the sewage tank and discharges the sewage through the liquid drop. This scheme will cause dirt to hang on the wall. The other is the negative pressure sewage discharge scheme, which is to add a fan inside the base station, first evacuate the sewage storage container in the base station, then suck the sewage in the sewage tank into the sewage storage container, and then pressurize it, and finally discharge the sewage in the storage container. This scheme has a complex structure and high cost. Therefore, how to quickly discharge the sewage of the floor scrubber and avoid dirt hanging on the wall in the sewage is an urgent problem to be solved.

[0037] Based on the above considerations, the present application designs a base station for a cleaning device, a cleaning device and a control method thereof. In the base station of the cleaning device, a first filter element is arranged at the sewage collecting port, and a second filter element is arranged in the sewage collecting chamber. The sewage discharged into the sewage collecting chamber is filtered at least twice before being discharged. This can effectively intercept solid dirt in the sewage and prevent the solid dirt in the sewage from clogging other components, which is beneficial to improving the sewage discharge efficiency and sewage discharge stability.

[0038] Please refer to Figures 1 to 3 In one embodiment, the base station 10 of the cleaning device includes a dirt collecting box 100, a first filter element 200 and a second filter element 300. The dirt collecting box 100 has a dirt collecting chamber 101 and a dirt collecting port 102 connected to the dirt collecting chamber 101. The dirt collecting port 102 is configured to input sewage into the dirt collecting chamber 101. The first filter element 200 is arranged at the dirt collecting port 102, and the second filter element 300 is arranged in the dirt collecting chamber 101.

[0039] It should be noted that the base station 10 of the cleaning device is used to dock with the floor scrubber 20 of the cleaning device, and the sewage collecting port 102 is configured to input sewage into the sewage collecting chamber 101. It can be understood that: when the base station 10 and the floor scrubber 20 are in a separated state, the sewage collecting port 102 is separated from the sewage tank 21 of the floor scrubber 20; when the base station 10 and the floor scrubber 20 are in a docked state, the sewage collecting port 102 is docked with the sewage tank 21 of the floor scrubber 20, and the sewage in the sewage tank 21 can be discharged into the sewage collecting chamber 101 through the sewage collecting port 102, and after being filtered by the first filter element 200 and the second filter element 300, it is discharged from the sewage collecting chamber 101 to the outside of the base station 10.

[0040] The base station 10 of the above-mentioned cleaning device has a first filter element 200 arranged at the sewage collecting port 102, and a second filter element 300 arranged in the sewage collecting chamber 101. The sewage discharged into the sewage collecting chamber 101 is filtered at least twice before being discharged, which can effectively intercept solid dirt in the sewage and prevent the solid dirt in the sewage from clogging other components, thereby helping to improve sewage discharge efficiency and sewage discharge stability.

[0041] In the embodiment of the present application, the sewage collecting box 100 is detachably arranged in the base station 10, so as to facilitate taking out the sewage collecting box 100 from the base station 10, and then facilitate pouring out the sewage in the sewage collecting box 100 and cleaning the sewage collecting box 100, thereby improving the user experience. The shape of the sewage collecting box 100 can be a rectangular parallelepiped, a cylinder or other structures, which can be flexibly set according to needs and is not limited here.

[0042] In the embodiment of the present application, the number of sewage collecting ports 102 is not limited to one. When the number of sewage collecting ports 102 is at least two, the shapes and sizes of the sewage collecting ports 102 may be the same or different. For example, the shape of the sewage collecting ports 102 may be circular, square, etc. The number, shape and size of the sewage collecting ports 102 are not limited herein.

[0043] In the embodiments of the present application, the first filter element 200 and the second filter element 300 can be the same type of filtering structure or different types of filtering structures; for example, the first filter element 200 and the second filter element 300 can be a box-like structure with one end open, a mesh structure, or other structures such as a net bag, and the structural type of the first filter element 200 and the second filter element 300 is not limited herein.

[0044] Specifically, please refer to Figure 1 , the filtering efficiency of the second filter element 300 is greater than the filtering efficiency of the first filter element 200 .

[0045] It should be noted that filtration efficiency refers to the ratio of the weight or number of particles captured by the filter to the weight or number of particles contained in the air before filtration. Filtration efficiency is an indicator to measure the ability of the filter to capture dust particles.

[0046] Here, the filtering efficiency of the second filter element 300 is made greater than that of the first filter element 200. The large particles of impurities in the sewage can be initially filtered out by the first filter element 200, and the small particles of impurities in the sewage can be filtered out again by the second filter element 300, thereby improving the filtering accuracy and filtering effect of impurities in the sewage.

[0047] For details about this embodiment, please refer to Figure 1 The first filter element 200 is a primary filter.

[0048] It should be noted here that there are many types of primary filters, which may be a box-like structure with an open top, a mesh structure, a net bag or other structures. For example, the primary filter may be a primary paper frame filter or a primary aluminum frame filter.

[0049] Please refer to Figure 1 The sewage collecting box 100 also has a sewage outlet 103 connected to the sewage collecting chamber 101 . The sewage outlet 103 is configured to output the sewage in the sewage collecting chamber 101 . The sewage outlet 103 is arranged at the bottom side of the sewage collecting box 100 .

[0050] It can be understood that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage collecting port 102 is docked with the sewage tank 21 of the floor scrubber 20, and the sewage in the sewage tank 21 can be discharged into the sewage collecting chamber 101 through the sewage collecting port 102, and after being filtered by the first filter element 200 and the second filter element 300, it is discharged from the sewage outlet 103 of the sewage collecting chamber 101 to the outside of the base station 10.

[0051] In the embodiments of the present application, the number of sewage outlets 103 is not limited to one. When the number of sewage outlets 103 is at least two, the shapes and sizes of each sewage outlet 103 can be the same or different. For example, the shape of each sewage outlet 103 can be circular, square, etc. The number, shape and size of the sewage collection outlet 102 are not limited herein.

[0052] In the embodiment of the present application, the sewage outlet 103 is arranged at the bottom side of the sewage collecting box 100, and the sewage outlet 102 is arranged at the top side of the sewage collecting box 100, so that the sewage can be discharged from top to bottom, reducing the resistance and energy consumption of sewage discharge.

[0053] For further information, please refer to Figure 4 The number of the second filter elements 300 is at least two, and the second filter elements 300 are spaced apart and distributed along the height direction of the dirt collecting chamber 101 .

[0054] It should be noted that the height direction of the dirt collecting chamber 101 is Figure 4By distributing the second filter elements 300 at intervals along the height direction of the sewage collecting chamber 101, after the sewage is discharged into the sewage collecting chamber 101 of the base station 10 from the sewage collecting port 102, it is filtered by the first filter element 200 in the sewage collecting chamber 101 and then filtered again by the second filter element 300 at least twice, which can more effectively intercept solid dirt in the sewage.

[0055] In the embodiment of the present application, the second filter elements 300 may be distributed at equal intervals or at non-equal intervals along the height direction of the dirt collecting chamber 101. The sizes and shapes of the second filter elements 300 may be the same or different, and the spacing, size and shape of the second filter elements 300 are not limited here.

[0056] For further information, please refer to Figure 4 , in the direction from the sewage collecting port 102 to the sewage discharging port 103 , the filtering efficiency of each second filter element 300 gradually increases.

[0057] It is understandable that the filtering efficiency of each second filter element 300 gradually increases, that is, each second filter element 300 can filter finer and finer particles. Through the above arrangement, in the direction from the sewage collection port 102 to the sewage discharge port 103, large particles of impurities in the sewage can be filtered first, and then small particles of impurities in the sewage can be filtered, thereby improving the filtering accuracy and filtering effect of impurities in the sewage.

[0058] In the embodiment of the present application, the filtering efficiency of each second filter element 300 gradually increases, and the increasing gradient may be linear or nonlinear.

[0059] For details about this embodiment, please refer to Figure 4 , each second filter element 300 is a medium efficiency filter and / or a high efficiency filter.

[0060] Here, there are many types of medium efficiency filters, for example, medium efficiency filters can be plate-type medium efficiency filters or medium efficiency bag filters, and the number of medium efficiency filters is not limited to one, and the type and number of medium efficiency filters are not limited here. There are many types of high-efficiency filters, such as activated carbon filters or HEPA filters, and the number of high-efficiency filters is not limited to one, and the type and number of high-efficiency filters are not limited here.

[0061] In the embodiment of the present application, all second filter elements 300 may be medium-efficiency filter screens, or all may be high-efficiency filter screens, or a portion may be a medium-efficiency filter screen and the other portion may be a high-efficiency filter screen.

[0062] Please refer to Figure 1 The base station 10 of the cleaning device further includes a driving pump 400 and a sewage pipe 500 . The sewage pipe 500 is connected to the sewage outlet 103 . The driving pump 400 is disposed in the sewage pipe 500 and is used to provide driving power for the sewage pipe 500 .

[0063] It can be understood that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage collecting port 102 is docked with the sewage tank 21 of the floor scrubber 20, and the sewage in the sewage tank 21 can be discharged into the sewage collecting chamber 101 from the sewage collecting port 102, and after being filtered by the first filter element 200 and the second filter element 300, it flows into the sewage pipe 500 from the sewage outlet 103. Under the driving action of the driving pump 400, the sewage in the sewage pipe 500 is quickly discharged to the outside of the base station 10.

[0064] In an embodiment of the present application, the sewage pipe 500 is connected to the sewage outlet 103, and the sewage pipe 500 and the sewage collecting box 100 are detachably connected. For example, the sewage pipe 500 and the sewage collecting box 100 can be fixed by snap connection, screw connection, etc.; the sewage pipe 500 and the sewage collecting box 100 can also be non-detachably connected, for example, fixed by riveting, welding, etc.

[0065] In the embodiment of the present application, the sewage pipe 500 is a hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube, an elliptical tube, etc. The number of the sewage pipe 500 is not limited to one, that is, the number of the sewage pipe 500 can be at least two.

[0066] In the embodiment of the present application, the driving pump 400 may be a mechanical pump, an electromagnetic pump or other types of driving structures capable of providing driving power. The number of the driving pumps 400 is not limited to one, that is, the number of the driving pumps 400 may be at least two.

[0067] Please refer to Figure 4 and Figure 5 The base station 10 of the cleaning device further comprises a clean water tank 600 disposed above the dirt collecting tank 100, the clean water tank 600 having a clean water chamber 601, and the clean water chamber 601 is configured to be connected to the dirty water tank 21 of the floor scrubber 20 in the cleaning device. The filtering efficiency of the second filter element 300 is greater than the filtering efficiency of the first filter element 200.

[0068] It should be noted that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage collecting port 102 is docked with the sewage tank 21 of the floor scrubber 20, and the sewage in the sewage tank 21 is first discharged from the sewage collecting port 102 into the sewage collecting chamber 101, and then discharged to the outside of the base station 10 after being filtered by the first filter element 200 and the second filter element 300, so as to intercept the solid dirt in the sewage; then, under the driving action of the driving pump 400, the clean water in the clean water chamber 601 is sucked into the sewage tank 21 and the sewage collecting chamber 101 in turn, and is discharged after being filtered by the first filter element 200 and the second filter element 300, so as to avoid the dirt in the sewage from hanging on the inner wall of the sewage tank 21.

[0069] In the examples of this application, reference is made to Figure 4 and Figure 5The sewage tank 21 also has a water inlet 21b, which is connected to the clean water chamber 601 through a clean water pipe 700. The clean water pipe 700 is a hollow tubular structure, which can be in other shapes such as a circular tube and an elliptical tube. The number of clean water pipes 700 is not limited to one, that is, the number of sewage pipes 500 can be at least two. The number of water inlets 21b is not limited to one. When the number of water inlets 21b is at least two, the shape and size of each water inlet 21b can be the same or different. For example, the shape of each water inlet 21b can be circular, square, etc. The number, shape and size of the water inlet 21b are not limited here.

[0070] In the embodiment of the present application, the clean water tank 600 is detachably arranged in the base station 10, so that the clean water tank 600 can be taken out from the base station 10, thereby improving the user experience. The clean water tank 600 can be in the shape of a cuboid, a cylinder or other structures, which can be flexibly arranged according to the needs and is not limited here.

[0071] Please refer to Figures 1 to 3 The cleaning device in one embodiment includes the above-mentioned cleaning device base station 10 and a floor scrubber 20 . The floor scrubber 20 includes a sewage tank 21 . The sewage tank 21 has a water outlet 21 a . The water outlet 21 a is connected to the sewage collection port 102 .

[0072] It should be noted that the water outlet 21a is connected to the sewage collecting port 102, which can be understood as follows: when the base station 10 and the floor scrubber 20 are in a separated state, the sewage collecting port 102 and the water outlet 21a are separated from each other; when the base station 10 and the floor scrubber 20 are in a docked state, the sewage collecting port 102 and the water outlet 21a are docked and connected.

[0073] In the above-mentioned cleaning device, the first filter element 200 is arranged at the sewage collecting port 102, and the second filter element 300 is arranged in the sewage collecting chamber 101. The sewage discharged into the sewage collecting chamber 101 is filtered at least twice before being discharged, which can effectively intercept the solid dirt in the sewage and prevent the solid dirt in the sewage from clogging other components, which is beneficial to improving the sewage discharge efficiency and sewage discharge stability.

[0074] In the embodiment of the present application, the sewage tank 21 is detachably arranged in the floor scrubber 20, so as to facilitate taking out the sewage tank 21 from the floor scrubber 20. The shape of the sewage tank 21 can be a rectangular parallelepiped, a cylinder or other structures, which can be flexibly set according to needs and is not limited here.

[0075] In the embodiment of the present application, the number of water outlets 21a is not limited to one. When the number of water outlets 21a is at least two, the shapes and sizes of each water outlet 21a may be the same or different. For example, the shape of each water outlet 21a may be circular, square, etc. The number, shape and size of the water outlets 21a are not limited here.

[0076] Specifically, please refer to Figures 1 to 3 The floor scrubber 20 further includes a control valve and a connecting pipe 22 . The connecting pipe 22 is disposed between the water outlet 21 a and the sewage collecting port 102 . The control valve is disposed between the connecting pipe 22 and is used to control the opening and closing of the connecting pipe 22 .

[0077] It can be understood that when the base station 10 and the floor scrubber 20 are in a separated state, the sewage collecting port 102 and the water outlet 21a are separated from each other, and the control valve controls the connecting pipe 22 to close; when the base station 10 and the floor scrubber 20 are in a docked state, the sewage collecting port 102 and the water outlet 21a are docked and connected. When the sewage needs to be discharged, the control valve controls the connecting pipe 22 to open, so that the sewage in the sewage tank 21 can be discharged into the sewage collecting chamber 101 from the sewage collecting port 102.

[0078] In the embodiment of the present application, the control valve may be a solenoid valve, that is, the valve is driven to open and close by a motor to control the opening and closing of the connecting pipe 22. In other embodiments, the control valve may also be a mechanical valve or other types of valves.

[0079] In an embodiment of the present application, the connecting pipe 22 is arranged between the water outlet 21a and the sewage collecting port 102, and the connecting pipe 22 and the sewage collecting box 100 are detachably connected. For example, the connecting pipe 22 and the sewage collecting box 100 can be fixed by snap connection, screw connection, etc.; the connecting pipe 22 and the sewage collecting box 100 can also be non-detachably connected, for example, fixed by riveting, welding, etc.

[0080] In the embodiment of the present application, the connecting pipe 22 is a hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube, an elliptical tube, etc. The number of the connecting pipes 22 is not limited to one, that is, the number of the sewage pipes 500 can be at least two.
