The first docking part and the second docking part are detachably connected. When the surface cleaning device is placed on the base station, the first docking part and the second docking part are connected and communicated. When the surface cleaning device is removed from the base station, the first docking part and the second docking part are separated from each other. The base station includes a water supply water pump and a switching valve. The outlet of the water supply water pump is communicated with the inlet of the switching valve. The first outlet of the switching valve is communicated with the second docking part, and the second outlet of the switching valve is communicated with the base station spray hole of the base station. When the surface cleaning device is placed on the base station, the base station spray hole is used to clean the floor brush of the surface cleaning device placed on the base station.

The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present utility model can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.

[0025] As Figures 1 to 5 shown is a structural schematic block diagram of a surface cleaning device having a base station, including a base station 1 and a surface cleaning device 2. The surface cleaning device 2 is provided with a first docking portion 18, and the base station 1 is provided with a second docking portion 3. The first docking portion 18 and the second docking portion 3 are detachably connected. When the surface cleaning device 2 is placed on the base station 1, the first docking portion 18 and the second docking portion 3 are connected and communicate. When the surface cleaning device 2 is removed from the base station 1, the first docking portion 18 and the second docking portion 3 are separated from each other. The base station 1 includes a water supply pump 4, and the surface cleaning device 2 includes a first three-way joint 5 and a floor brush water pump. The inlet of the water supply pump 4 is communicated with the water source of the base station 1, and the outlet of the water supply pump 4 is communicated with the second docking portion 3. The first end of the first three-way joint 5 is communicated with the clean water tank 7 of the surface cleaning device 2, the second end of the first three-way joint 5 is communicated with the first docking portion 18, the third end of the first three-way joint 5 is communicated with the inlet of the floor brush water pump, and the outlet of the floor brush water pump is communicated with the floor brush water spraying holes of the surface cleaning device 2; when the first docking portion 18 and the second docking portion 3 are connected and communicate, the water source sequentially supplies water to the clean water tank 7 through the water supply pump 4, the second docking portion 3, the first docking portion 18, and the first three-way joint 5, and the floor brush water pump serves as a stop valve to prevent the first three-way joint 5 from communicating with the floor brush water spraying holes. The floor brush water pump is, for example, a peristaltic pump, which is in a cut-off state when powered off, thus forming the function of a stop valve.

[0026] In this way, through improvement, the water source sequentially supplies water to the water purification tank 7 through the water supply pump 4, the second docking part 3, the first docking part 18, and the first three-way joint 5. The floor brush pump acts as a cut-off valve to prevent the first three-way joint 5 from communicating with the floor brush spray holes. That is, when the water source supplies water to the water purification tank 7, the floor brush pump is in a cut-off state, and the fluid pumped by the water supply pump 4 will not leak from the floor brush pump, realizing normal water supply, that is, supplying water from the water source to the water purification tank 7. Therefore, the technical solution of the present disclosure can more simply and reliably achieve water supply.

[0027] The water source can be tap water or an independent water tank. In this example, it is mainly exemplified that the base station 1 is provided with a base station water tank 6, so as to achieve the purpose of flexible placement of the base station 1.

[0028] The first docking part 18 and the second docking part 3 can adopt quick docking joints, such as Figure 4 As shown, for example, the surface cleaning device 2 is a floor washer. When the surface cleaning device 2 is placed on the base station 1, the first docking part 18 and the second docking part 3 are quickly docked. The first docking part 18 is set as a socket, and the second docking part 3 is set as a plug. The socket and the plug are inserted up and down, as Figure 5 As shown, when the surface cleaning device 2 is removed from the base station 1, the socket and the plug are separated up and down, so that the first docking part 18 and the second docking part 3 are separated from each other.

[0029] In some embodiments, as Figures 1 to 5 As shown, it further includes a switching valve 9. The outlet of the water supply pump 4 is communicated with the inlet of the switching valve 9. The first outlet of the switching valve 9 is communicated with the second docking part 3. The communication between the outlet of the water supply pump 4 and the second docking part 3 means that the outlet of the water supply pump 4 is communicated with the second docking part 3 through the switching valve 9. The second outlet of the switching valve 9 is communicated with the base station spray holes 14 of the base station 1. When the surface cleaning device 2 is placed on the base station 1, the base station spray holes 14 are used to clean the floor brush 8 of the surface cleaning device 2 placed on the base station 1. This solution solves the problem that when the liquid in the water purification tank 7 is used up after the surface cleaning device 2 mops the floor, it is not necessary to add liquid again, but directly use the water source for self-cleaning. At the same time, the following solution can further mix the cleaning liquid and high-temperature hot water, making it easier to clean the roller brush of the floor brush 8.

[0030] The switching valve 9 is, for example, an electromagnetic valve, and the water supply or cleaning is selected in an electric control manner.

[0033] In some embodiments, as Figures 1 to 5 shown, it further includes a second three-way joint 11, a cleaning liquid tank 12 and a liquid supply pump 13. The cleaning liquid tank 12 is communicated with the inlet of the liquid supply pump 13. The outlet of the liquid supply pump 13 is communicated with the first end of the second three-way joint 11. The second outlet of the switching valve 9 is communicated with the second end of the second three-way joint 11. The third end of the second three-way joint 11 is communicated with the base station spray hole 14. The second three-way joint 11 is used to mix the cleaning liquid in the cleaning liquid tank 12 and the liquid of the water source to clean the floor brush 8 of the surface cleaning device 2. In this way, better cleaning ability can be provided.

[0034] In some embodiments, as Figure 1 、 5 shown, it further includes a first electrical connection joint provided on the surface cleaning device 2 and a second electrical connection joint 15 provided on the base station 1. The first electrical connection joint and the second electrical connection joint 15 are detachably electrically connected. When the surface cleaning device 2 is placed on the base station 1, the first electrical connection joint and the second electrical connection joint 15 are electrically connected for communication and / or power supply to the surface cleaning device 2. When the surface cleaning device 2 is removed from the base station 1, the first electrical connection joint and the second electrical connection joint 15 are separated from each other. As Figure 5 shown, after the first electrical connection joint and the second electrical connection joint 15 are electrically connected, communication can be carried out and power supply can be provided to the surface cleaning device 2 for charging. That is, the second electrical connection joint 15 includes a charging seat 20 and a communication seat 21, and the first electrical connection joint is provided with corresponding electrical connection terminals.

[0035] In some embodiments, as Figure 1 、 2 shown, it further includes a liquid level sensor 16 provided on the surface cleaning device 2. The liquid level sensor 16 is used to detect the liquid level of the clean water tank 7. When the liquid level is lower than the set value, and when the surface cleaning device 2 is placed on the base station 1, the surface cleaning device 2 is electrically connected through the first electrical connection joint and the second electrical connection joint 15 to transmit the liquid adding required signal and / or the current liquid level signal to the control unit of the base station 1, and the control unit controls the water supply pump 4 to work to add liquid to the clean water tank 7 to the set value.

[0036] In some embodiments, as Figure 1 shown, for the case with the switching valve 9, the switching valve 9 is electrically connected to the control unit. The control unit is used to control the switching valve 9 to select whether to add liquid or clean the floor brush 8 of the surface cleaning device 2 placed on the base station 1. Generally, it is to clean the roller brush installed on the floor brush 8, as Figure 5As shown, a plurality of base station water spray holes 14 are arranged along the axial direction of the roller brush on the base station 1, so as to provide a larger cleaning area.

The switch 17 is used to electrically connect the power supply and the boiler 10. The switch 17 is a power switch, and the user directly operates the power switch to connect the power supply and the boiler 10, so that the boiler 10 provides hot liquid.

The control interface 19 is for the user to operate to select liquid addition or cleaning, and liquid addition and cleaning can be selected by the user.

[0040] The control interface 19 can be a touch interface or a mechanical switch.

[0041] The control interface 19 can be arranged on the base station 1, or on the surface cleaning device 2, or the function of the control interface 19 is divided into two parts, one part is arranged on the base station 1 and the other part is arranged on the surface cleaning device 2.
