[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 cleaning device and a base station thereof, in which a sewage pipe is arranged at the sewage outlet, and the sewage pipe includes a bent pipe section and a siphon pipe section connected to the bent pipe section. The siphon force generated by the siphon pipe section can accelerate the flow rate of sewage through the sewage pipe, increase the flushing force, and improve the situation of solid dirt in the sewage hanging on the wall. The structure is simple and is conducive to improving 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 sewage collecting box 100 and a sewage discharge pipe 200. The sewage collecting box 100 has a sewage collecting chamber 101 and a sewage discharge port 103 connected to the sewage collecting chamber 101. The sewage discharge port 103 is configured to output the sewage in the sewage collecting chamber 101, and the sewage discharge pipe 200 is arranged at the sewage discharge port 103; wherein, the sewage discharge pipe 200 includes a siphon pipe section 210 and a bent pipe section 220, one end of the bent pipe section 220 is connected to the sewage discharge port 103, the siphon pipe section 210 is connected to the end of the bent pipe section 220 away from the sewage discharge port 103, and the siphon pipe section 210 is configured to provide a siphon force for the sewage discharge pipe 200.

[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 outlet 103 is configured to output the sewage in 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 chamber 101 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 chamber 101 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. Under the siphon force, the sewage in the sewage collecting chamber 101 flows through the sewage outlet 103, the bent pipe section 220, and the siphon pipe section 210 in sequence and is discharged to the outside of the base station 10.

[0040] The base station 10 of the above-mentioned cleaning device sets the sewage pipe 200 at the sewage outlet 103, and the sewage pipe 200 includes a bent pipe section 220 and a siphon pipe section 210 connected to the bent pipe section 220. The siphon force generated by the siphon pipe section 210 can accelerate the flow rate of sewage through the sewage pipe 200, increase the flushing force, and improve the situation of solid dirt in the sewage hanging on the wall. The structure is simple and is conducive to improving 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 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 may be the same or different. For example, the shape of each sewage outlet 103 may be circular, square, etc. The number, shape and size of the sewage outlet 103 are not limited herein.

[0043] In an embodiment of the present application, the sewage pipe 200 is connected to the sewage outlet 103, and the sewage pipe 200 and the sewage collecting box 100 are detachably connected. For example, the sewage pipe 200 and the sewage collecting box 100 can be fixed by means of snap connection, screw connection, etc.; the sewage pipe 200500 and the sewage collecting box 100 can also be non-detachably connected, for example, fixed by means of riveting, welding, etc.

[0044] In the embodiment of the present application, the sewage pipe 200 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 pipes 200 is not limited to one, that is, the number of the sewage pipes 200 can be at least two.

[0045] Specifically, please refer to Figure 4 The bent tube section 220 includes a first bent portion 221 and a second bent portion 222, and the second bent portion 222 is disposed between the first bent portion 221 and the siphon tube section 210; the bending direction of the first bent portion 221 is upward, and the bending direction of the second bent portion 222 is downward.

[0046] Here, the bending direction of the first bending portion 221 is upward, that is, along Figure 4 The Z direction is upward; the bending direction of the second bending portion 222 is downward, that is, along Figure 4 The Z direction is shown in the opposite direction downward.

[0047] It can be understood that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage collecting chamber 101 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. Under the action of the siphon force, the sewage in the sewage collecting chamber 101 flows through the sewage outlet 103, the bent pipe section 220, and the siphon pipe section 210 in sequence and is discharged to the outside of the base station 10; thereafter, due to the setting of the first bending portion 221, part of the liquid (such as clean water) can be stored in the first bending portion 221, and this liquid will block the air exchange between the outside and the sewage collecting chamber 101, thereby preventing the odor of the sewage collecting chamber 101 from flowing back into the room.

[0048] In the embodiment of the present application, the first bending portion 221 and the second bending portion 222 are both arc-shaped tubular structures, and the bending directions of the two are opposite. The inner diameters of the first bending portion 221 and the second bending portion 222 may be equal or unequal.

[0049] In the embodiment of the present application, the number of the first bending portions 221 and the second bending portions 222 is not limited to one, that is, the number of the first bending portions 221 and the second bending portions 222 can be at least two, and the shape and size of each first bending portion 221 can be the same or different, and the shape and size of each second bending portion 222 can be the same or different.

[0050] For details about this embodiment, please refer to Figure 4 , the first bending portion 221 is constructed as a U-shaped structure.

[0051] It should be noted here that the U-shaped structure is a U-shaped hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube, an elliptical tube, etc.

[0052] For details about this embodiment, please refer to Figure 4 The second bending portion 222 is constructed as an inverted U-shaped structure.

[0053] It should be noted here that the inverted U-shaped structure is an inverted U-shaped hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube, an elliptical tube, etc.

[0054] Please refer to Figure 5 The base station 10 of the cleaning device further includes an air pressure balance pipe 300 , which is connected to the siphon section 210 and can communicate with the atmosphere.

[0055] It can be understood that when the air pressure balance pipe 300 is connected to the atmosphere, the siphon section 210 and the bent pipe section 220 are also connected to the atmosphere. When part of the liquid (for example, clean water) is stored in the first bend portion 221, it can prevent part of the liquid in the first bend portion 221 from being unable to be stored due to excessively high or low air pressure, and can enable part of the liquid to be smoothly stored in the first bend portion 221 to block the air exchange between the outside world and the sewage collecting chamber 101, thereby preventing the odor of the sewage collecting chamber 101 from flowing back into the room.

[0056] In the embodiments of the present application, the air pressure balance pipe 300 can be connected to the atmosphere, which can be understood as: the air pressure balance pipe 300 is always in an open state; or the air pressure balance pipe 300 is arranged at a valve, and the air pressure balance pipe 300 is connected to the atmosphere only when the valve is opened, and the air pressure balance pipe 300 is isolated from the atmosphere when the valve is closed.

[0057] In the embodiment of the present application, the air pressure balance tube 300 is a hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube, an elliptical tube, etc.

[0058] For further information, please refer to Figure 5 The air pressure balance pipe 300 is vertically connected to the siphon pipe section 210 .

[0059] In an embodiment of the present application, the air pressure balance pipe 300 and the sewage pipe 200 can be detachably connected, for example, the air pressure balance pipe 300 and the sewage pipe 200 can be fixed by means of snap connection, screw connection, etc.; the air pressure balance pipe 300 and the sewage pipe 200 can also be non-detachably connected, for example, fixed by means of riveting, welding, etc.

[0060] For details about this embodiment, please refer to Figure 5 The inner diameter of the air pressure balance tube 300 ranges from 5 mm to 10 mm.

[0061] Here, since the pressure balance pipe 300 is connected to the siphon section 210 and can communicate with the atmosphere, the pressure balance pipe 300 plays a role in connecting the siphon section 210 with the atmosphere. Through the above configuration, the inner diameter range of the pressure balance pipe 300 is limited, so that the pressure balance pipe 300 can be connected with the atmosphere without occupying too much space.

[0062] For details about this embodiment, please refer to Figure 5 The inner diameter of the siphon tube section 210 is in the range of 20 mm to 30 mm.

[0063] Here, since the siphon section 210 plays a role in generating siphon force, the flow rate of sewage through the sewage pipe 200 can be accelerated. Through the above configuration, the inner diameter range of the siphon section 210 is limited, so that the siphon section 210 can generate siphon force without occupying too much space.

[0064] Please refer to Figure 5 The base station 10 of the cleaning device further includes a clean water tank 400 disposed above the dirt collecting tank 100. The clean water tank 400 has a clean water chamber 401. The clean water chamber 401 is configured to be connected to the sewage tank 21 of the floor scrubber 20 in the cleaning device.

[0065] It should be noted that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage in the sewage tank 21 is first discharged into the sewage collecting chamber 101, and under the action of siphon, it is discharged to the outside of the base station 10 through the sewage outlet 103 and the sewage pipe 200 in sequence; then, the clean water in the clean water chamber 401 is sucked into the sewage tank 21 and the sewage collecting chamber 101 in sequence, and again under the action of siphon, it is discharged to the outside of the base station 10 through the sewage outlet 103 and the sewage pipe 200 in sequence to prevent the dirt in the sewage from sticking to the wall.

[0066] In the examples of this application, reference is made to Figure 4 and Figure 5 The sewage tank 21 also has a water inlet 21b, and the water inlet 21b is connected to the clean water chamber 401 through a clean water pipe 500. The clean water 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 clean water pipes 500 is not limited to one, that is, the number of the clean water pipes 500 can be at least two. The number of the water inlet 21b is not limited to one. When the number of the water inlet 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., and the number, shape and size of the water inlet 21b are not limited here.

[0067] In the embodiment of the present application, the clean water tank 400 is detachably arranged in the base station 10, so that the clean water tank 400600 can be taken out from the base station 10, which improves the user experience. The clean water tank 400 can be in the shape of a cuboid, a cylinder or other structures, which can be flexibly arranged according to needs and is not limited here.

[0068] Please refer to Figure 6 and Figure 4 The cleaning device in one embodiment includes the base station 10 of the cleaning device and the floor scrubber 20. The dirt collecting box 100 also has a dirt collecting port 102 connected to the dirt collecting chamber 101. The floor scrubber 20 includes a sewage tank 21. The sewage tank 21 has a water outlet 21a. The water outlet 21a is connected to the dirt collecting port 102.

[0069] 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.

[0070] The above-mentioned cleaning device arranges the sewage pipe 200 at the sewage outlet 103, and the sewage pipe 200 includes a bent pipe section 220 and a siphon pipe section 210 connected to the bent pipe section 220. The siphon force generated by the siphon pipe section 210 can accelerate the flow rate of sewage through the sewage pipe 200, increase the flushing force, and improve the situation of solid dirt in the sewage hanging on the wall. The structure is simple and is conducive to improving sewage discharge efficiency and sewage discharge stability.

[0071] 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.

[0072] 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.

[0073] Specifically, please refer to Figure 6 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 .

[0074] 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.

[0075] 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.

[0076] 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.

[0077] In the embodiment of the present application, the connecting tube 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 tubes 22 is not limited to one, that is, the number of the connecting tubes 22 can be at least two.

[0078] More specifically, please refer to Figure 6 The floor scrubber 20 further includes a driving pump 23 , which is disposed on the connecting pipe 22 and is used to provide driving power for the connecting pipe 22 .

[0079] 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. Under the driving action of the driving pump 23, the sewage in the sewage tank 21 can be quickly discharged from the water outlet 21a into the sewage collecting port 102 and the sewage collecting chamber 101.

[0080] In the embodiment of the present application, the driving pump 23 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 23 is not limited to one, that is, the number of the driving pumps 23 may be at least two.
