Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device and its base station. Background Technology

[0002] As people pay more and more attention to indoor air quality, floor scrubbers, as cleaning equipment that integrates vacuuming, mopping, and washing, are gradually becoming one of the essential household appliances. At the same time, people are increasingly pursuing high-performance floor scrubbers, and the base station model of the floor scrubber solves the problem of frequently changing clean water and emptying wastewater.

[0003] Currently, there are two main methods for wastewater discharge in floor scrubbers used in base stations. One is a direct discharge method, where the wastewater tank valve is opened and the wastewater is discharged by liquid drop. This method can result in dirt sticking to the walls. The other is a negative pressure discharge method, which involves adding a fan inside the base station to first evacuate the wastewater storage container, then sucking the wastewater from the wastewater tank into the storage container, pressurizing it, and finally discharging the wastewater from the storage container. This method is complex and costly. Therefore, how to quickly discharge wastewater from the floor scrubber while preventing dirt from sticking to the walls is a problem that urgently needs to be solved. Utility Model Content

[0035] As people pay more and more attention to indoor air quality, floor scrubbers, as cleaning equipment that integrates vacuuming, mopping, and washing, are gradually becoming one of the essential household appliances. At the same time, people are increasingly pursuing high-performance floor scrubbers, and the base station model of the floor scrubber solves the problem of frequently changing clean water and emptying wastewater.

[0036] Currently, there are two main methods for wastewater discharge in floor scrubbers used in base stations. One is a direct discharge method, where the wastewater tank valve is opened and the wastewater is discharged by liquid drop. This method can result in dirt sticking to the walls. The other is a negative pressure discharge method, which involves adding a fan inside the base station to first evacuate the wastewater storage container, then sucking the wastewater from the wastewater tank into the storage container, pressurizing it, and finally discharging the wastewater from the storage container. This method is complex and costly. Therefore, how to quickly discharge wastewater from the floor scrubber while preventing dirt from sticking to the walls is a problem that urgently needs to be solved.

[0037] Based on the above considerations, this application designs a cleaning device and its base station, with a sewage pipe installed at the sewage outlet. The sewage pipe includes a bent pipe section and a siphon pipe section connected to the bent pipe section. By utilizing the siphon force generated by the siphon pipe section, the flow rate of sewage through the sewage pipe can be accelerated, the flushing force can be increased, and the situation of solid dirt in sewage adhering to the wall can be improved. The structure is simple and 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 sludge collection tank 100 and a sewage pipe 200. The sludge collection tank 100 has a sludge collection chamber 101 and a sewage outlet 103 communicating with the sludge collection chamber 101. The sewage outlet 103 is configured to discharge sewage from the sludge collection chamber 101. The sewage pipe 200 is disposed at the sewage outlet 103. The sewage pipe 200 includes a siphon section 210 and a bent section 220. One end of the bent section 220 is connected to the sewage outlet 103, and the siphon section 210 is connected to the end of the bent section 220 away from the sewage outlet 103. The siphon section 210 is configured to provide a siphon force for the sewage pipe 200.

[0039] It should be noted that the base station 10 of the cleaning device is used to connect with the floor scrubber 20 of the cleaning device, and the drain outlet 103 is configured to output the sewage in the collection chamber 101. This can be understood as follows: when the base station 10 and the floor scrubber 20 are in a separated state, the collection 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 connected state, the collection chamber 101 is connected to the sewage tank 21 of the floor scrubber 20, and the sewage in the sewage tank 21 can be discharged into the collection chamber 101. Under the siphon force, the sewage in the collection chamber 101 flows through the drain outlet 103, the bend pipe section 220, and the siphon pipe section 210 in sequence before being discharged to the outside of the base station 10.

[0040] The base station 10 of the aforementioned cleaning device has a sewage pipe 200 installed at the sewage outlet 103. 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 sewage adhering to the wall. The structure is simple and conducive to improving sewage discharge efficiency and sewage discharge stability.

[0041] In the embodiments of this application, the sludge collection box 100 is detachably disposed within the base station 10, so as to facilitate the removal of the sludge collection box 100 from the base station 10, thereby facilitating the emptying of the sewage in the sludge collection box 100 and the cleaning of the sludge collection box 100, thus improving the user experience. The shape of the sludge collection box 100 can be a cuboid, cylinder, or other structures, and can be flexibly designed as needed, without limitation here.

[0042] In the embodiments of this application, the number of drain outlets 103 is not limited to one. When the number of drain outlets 103 is at least two, the shape and size of each drain outlet 103 can be the same or different. For example, the shape of each drain outlet 103 can be circular, square, etc. The number, shape and size of the drain outlets 103 are not limited here.

[0043] In the embodiments of this application, the sewage pipe 200 is connected to the sewage outlet 103, and the sewage pipe 200 and the sewage collection box 100 are detachably connected. For example, the sewage pipe 200 and the sewage collection box 100 can be fixed by means of snap-fit, screw connection or other methods. The sewage pipe 200 and the sewage collection box 100 can also be non-detachably connected, for example, fixed by means of riveting, welding or other methods.

[0044] In the embodiments of this application, the sewage pipe 200 is a hollow tubular structure, and the tubular structure can be in other shapes such as round or elliptical. The number of sewage pipes 200 is not limited to one, that is, the number of sewage pipes 200 can be at least two.

[0045] For details, please refer to Figure 4 The bent pipe section 220 includes a first bent portion 221 and a second bent portion 222. The second bent portion 222 is located between the first bent portion 221 and the siphon pipe 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 bend 221 is upward, that is, along... Figure 4 The Z-direction is upward; the bending direction of the second bend 222 is downward, that is, along... Figure 4 The Z direction shown is downwards in the opposite direction.

[0047] Understandably, when the base station 10 and the floor scrubber 20 are in a docked state, the sludge collection chamber 101 is docked with the wastewater tank 21 of the floor scrubber 20. The wastewater in the wastewater tank 21 can be discharged into the sludge collection chamber 101. Under the siphon force, the wastewater in the sludge collection chamber 101 flows through the drain outlet 103, the bent pipe section 220, and the siphon pipe section 210 in sequence before being discharged to the outside of the base station 10. After that, due to the setting of the first bend 221, some liquid (such as clean water) can be stored in the first bend 221. This liquid will block the air exchange between the outside and the sludge collection chamber 101, thereby preventing the odor of the sludge collection chamber 101 from flowing back into the room.

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

[0049] In the embodiments of this application, the number of the first bending portion 221 and the second bending portion 222 is not limited to one, that is, the number of the first bending portion 221 and the second bending portion 222 can both 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 a specific embodiment, please refer to Figure 4 The first bend 221 is constructed as a U-shaped structure.

[0051] It should be noted that the U-shaped structure is a U-shaped hollow tubular structure, and the tubular structure can be in other shapes such as round tubular or elliptical tubular.

[0052] For a specific embodiment, please refer to Figure 4 The second bend 222 is constructed as an inverted U-shaped structure.

[0053] It should be noted 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 or an elliptical tube.

[0054] Please refer to Figure 5 The base station 10 of the cleaning device also includes a pressure balancing pipe 300, which is connected to the siphon section 210 and can be connected to the atmosphere.

[0055] Understandably, when the pressure balance pipe 300 is connected to the atmosphere, the siphon pipe section 210 and the bent pipe section 220 are also connected to the atmosphere. When some liquid (such as clean water) is stored in the first bend 221, it can prevent some liquid in the first bend 221 from being unable to be stored due to excessive or insufficient air pressure. It can ensure that some liquid is stored smoothly in the first bend 221, thereby blocking the air exchange between the outside and the sludge collection chamber 101, thus preventing the odor from the sludge collection chamber 101 from flowing back into the room.

[0056] In the embodiments of this application, the pressure balancing pipe 300 can be connected to the atmosphere, which can be understood as: the pressure balancing pipe 300 is always in an open state; or the pressure balancing pipe 300 is provided with a valve, and the pressure balancing pipe 300 is connected to the atmosphere only when the valve is open, and the pressure balancing pipe 300 is isolated from the atmosphere when the valve is closed.

[0057] In the embodiments of this application, the air pressure balance tube 300 is a hollow tubular structure, and the tubular structure can be in other shapes such as round tube or elliptical tube.

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

[0059] In the embodiments of this application, the air pressure balancing pipe 300 and the sewage pipe 200 can be detachably connected, for example, the air pressure balancing pipe 300 and the sewage pipe 200 can be fixed by means of snap-fit, screw connection or the like; the air pressure balancing pipe 300 and the sewage pipe 200 can also be non-detachably connected, for example, fixed by means of riveting, welding or the like.

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

[0061] Here, since the pressure balancing pipe 300 is connected to the siphon section 210 and can communicate with the atmosphere, the pressure balancing pipe 300 also serves to connect the siphon section 210 with the atmosphere. Through the above arrangement, the inner diameter range of the pressure balancing pipe 300 is limited, allowing the pressure balancing pipe 300 to communicate with the atmosphere without occupying excessive space.

[0062] For a specific embodiment, please refer to Figure 5 The inner diameter of the siphon section 210 ranges from 20mm to 30mm.

[0063] Here, the siphon section 210 generates a siphon force, accelerating the flow rate of sewage through the drain pipe 200. By limiting the inner diameter range of the siphon section 210, it is possible to generate a siphon force without occupying excessive space.

[0064] Please refer to Figure 5 The base station 10 of the cleaning device also includes a clean water tank 400 located above the sludge collection tank 100. The clean water tank 400 has a clean water cavity 401, which is configured to communicate with the wastewater 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 the docking state, the sewage in the sewage tank 21 is first discharged into the sewage collection chamber 101. Under the siphon force, 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 sequentially sucked into the sewage tank 21 and the sewage collection chamber 101. Again, under the siphon force, it is discharged to the outside of the base station 10 through the sewage outlet 103 and the sewage pipe 200 in sequence, so as to avoid dirt in the sewage from sticking to the wall.

[0066] In the embodiments of this application, reference is made to Figure 4 and Figure 5 The wastewater tank 21 also has a water inlet 21b, which is connected to the clean water chamber 401 via a clean water pipe 500. The clean water pipe 500 is a hollow tubular structure, and the tubular structure can be round, elliptical, or other shapes. The number of clean water pipes 500 is not limited to one; that is, the number of clean water 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 round, square, etc. There are no restrictions on the number, shape, and size of the water inlets 21b.

[0067] In the embodiments of this application, the clean water tank 400 is detachably disposed within the base station 10, so as to facilitate the removal of the clean water tank 400 from the base station 10, thereby improving the user experience. The clean water tank 400 can have a rectangular prism, cylinder, or other structures, and can be flexibly designed as needed; no limitation is made here.

[0068] Please refer to Figure 6 and Figure 4 In one embodiment, the cleaning device includes the base station 10 and the floor scrubber 20 described above. The sludge collection tank 100 also has a sludge collection port 102 that communicates with the sludge collection chamber 101. The floor scrubber 20 includes a wastewater tank 21, which has a water outlet 21a that is connected to the sludge collection port 102.

[0069] It should be noted that the water outlet 21a is connected to the sewage collection outlet 102. This can be understood as follows: when the base station 10 and the floor scrubber 20 are in a separated state, the sewage collection outlet 102 and the water outlet 21a are separated from each other; when the base station 10 and the floor scrubber 20 are in a connected state, the sewage collection outlet 102 and the water outlet 21a are connected and connected.

[0070] The aforementioned cleaning device has a drain pipe 200 located at the drain outlet 103. The drain 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 drain pipe 200, increase the flushing force, and improve the situation of solid dirt in sewage adhering to the wall. The structure is simple and is conducive to improving sewage discharge efficiency and sewage discharge stability.

[0071] In the embodiments of this application, the wastewater tank 21 is detachably disposed inside the floor scrubber 20 to facilitate removal of the wastewater tank 21 from the floor scrubber 20. The wastewater tank 21 can have a rectangular parallelepiped, cylindrical, or other shapes, and can be flexibly configured as needed; no limitation is made here.

[0072] In the embodiments of this application, the number of water outlets 21a is not limited to one. When the number of water outlets 21a is at least two, the shape and size of each water outlet 21a can be the same or different. For example, the shape of each water outlet 21a can be circular, square, etc. The number, shape and size of water outlets 21a are not limited here.

[0073] For details, please refer to Figure 6 The floor scrubber 20 also includes a control valve and a connecting pipe 22. The connecting pipe 22 is located between the water outlet 21a and the waste collection port 102. The control valve is located between the connecting pipes 22 and is used to control the opening and closing of the connecting pipes 22.

[0074] It is understandable that when the base station 10 and the floor scrubber 20 are in a separated state, the sewage collection port 102 and the water outlet 21a are separated from each other, and the control valve controls the connection pipe 22 to close at this time; when the base station 10 and the floor scrubber 20 are in a docked state, the sewage collection port 102 and the water outlet 21a are docked and connected. When sewage needs to be discharged, the control valve controls the connection pipe 22 to open so that the sewage in the sewage tank 21 can be discharged into the sewage collection chamber 101 through the sewage collection port 102.

[0075] In embodiments of this application, the control valve can be a solenoid valve, that is, the valve is opened and closed by a motor to control the opening and closing of the connecting pipe 22. In other embodiments, the control valve can also be a mechanical valve or other types of valves.

[0076] In the embodiments of this application, the connecting pipe 22 is located between the water outlet 21a and the sludge collection port 102. The connecting pipe 22 and the sludge collection box 100 are detachably connected. For example, the connecting pipe 22 and the sludge collection box 100 can be fixed by means of snap-fit, screw connection or other methods. The connecting pipe 22 and the sludge collection box 100 can also be non-detachably connected, for example, fixed by means of riveting, welding or other methods.

[0077] In the embodiments of this application, the connecting tube 22 is a hollow tubular structure, and the tubular structure can be in other shapes such as a circular tube or an elliptical tube. The number of connecting tubes 22 is not limited to one, that is, the number of connecting tubes 22 can be at least two.

[0078] For more specific details, please refer to Figure 6 The floor scrubber 20 also includes a drive pump 23, which is located on the connecting pipe 22 and is used to provide driving power to the connecting pipe 22.

[0079] It is understandable that when the base station 10 and the floor scrubber 20 are in a docking state, the sewage collection port 102 is docked with the sewage tank 21 of the floor scrubber 20. Under the drive of the pump 23, the sewage in the sewage tank 21 can be quickly discharged from the outlet 21a into the sewage collection port 102 and the sewage collection chamber 101.

[0080] In the embodiments of this application, the drive pump 23 can be a mechanical pump, an electromagnetic pump, or other types of drive structures capable of providing driving power. The number of drive pumps 23 is not limited to one; that is, the number of drive pumps 23 can be at least two.

[0081] Please refer to some embodiments of this application.

The sludge collection tank 100 has a sludge collection chamber 101 and a sewage outlet 103 communicating with the sludge collection chamber 101. The sewage outlet 103 is configured to discharge sewage from the sludge collection chamber 101. The sewage pipe 200 is disposed at the sewage outlet 103. The sewage pipe 200 includes a siphon section 210 and a bent section 220. One end of the bent section 220 is connected to the sewage outlet 103, and the siphon section 210 is connected to the end of the bent section 220 away from the sewage outlet 103. The siphon section 210 is configured to provide a siphon force for the sewage pipe 200. The clean water tank 400 is located above the sludge collection tank 100. The clean water tank 400 has a clean water chamber 401, which is configured to communicate with the wastewater tank 21 of the floor scrubber 20 in the cleaning device.

[0082] The bent pipe section 220 includes a first bent portion 221 and a second bent portion 222, with the second bent portion 222 disposed between the first bent portion 221 and the siphon pipe section 210; the first bent portion 221 is constructed as a U-shaped structure, and the second bent portion 222 is constructed as an inverted U-shaped structure.
