[0045] like Figure 1 and Figure 2 FIG. 1 is a structural perspective view of a working base station of a floor scrubbing robot provided in an embodiment of the present application, wherein the base station comprises:

[0046] A box body 100, wherein the bottom of the box body 100 has a water containing cavity 110;

[0047] A water collecting tank 120, which is disposed outside the housing 100 and communicated with the water containing chamber 110, and is used to collect waste water discharged by the floor scrubbing robot and introduce it into the water containing chamber 110;

[0048] The water supply assembly 200 includes a clean water injection end 210, a water supply pipeline 220, a water supply head 230 and a water supply valve 240. The clean water injection end 210 is used to inject clean water outside the device into the water supply pipeline 220. The water supply head 230 is connected to the water supply pipeline 220 and is used to inject clean water into the floor cleaning robot. The water supply valve 240 is used to control the on-off of the water circuit of the water supply head 230.

[0049] A liquid level monitor 300, used to detect the liquid level in the water containing chamber 110;

[0050] The drainage assembly 400 includes a drainage pump and a drainage pipe, and is used to discharge the waste water in the water containing chamber 110 to the outside of the device.

[0051] In the embodiment of the present application, the box 100 is a shell structure, and the bottom of the shell is enclosed to form a space capable of holding water, namely, a water chamber 110. At the same time, a water guide groove, namely, a water collection groove 120, is provided on the box 100, which can be provided outside the box 100, and its function is to collect waste water discharged by the floor cleaning robot and introduce it into the water chamber 110 for collection. Figure 4As shown, the clean water injection end 210 of the water supply assembly 200 can be connected to an external water pipe, and is used to connect the clean water source outside the base station device to the water supply pipeline 220. The water supply pipeline 220 and the water filling valve 240 can be arranged inside the box 100. Two clean water injection ends 210 can be arranged at the left and right opposite ends of the box 100, and both of them can be connected to the water supply pipeline 220, so that users can install and select according to their actual use. Similarly, two drainage ports are arranged on the box 100, and the sewage ports can be used to connect a longer sewage pipe to a floor drain or sewer, etc. The sewage ports are arranged on the left and right sides, and the drainage pipe can be connected to either end as needed.

[0052] The outstanding advantage of the embodiment of the present application is that compared with the existing robot base station using a split drawer-type independent water tank, the shell of the robot working base station box in the present application is used to hold water, and there is no need to set up an independent split clean water tank and sewage tank, and there is no internal installation and fixing structure, thus greatly reducing the cost and increasing the volume of the water tank. The shell structure is simple, avoiding the steps of installation and maintenance. The water supply component 200 of the base station in the present application directly injects external clean water into the robot through the water supply pipeline 220, and there is no need to set up an independent clean water containing component inside the base station, which provides a larger volume space for the sewage tank, saves production and manufacturing costs and improves the intensiveness of the base station, so that the base station can quickly recover sewage from the inside of the robot in a short time, thereby improving operating efficiency.

[0053] like Figure 3 As shown, as a preferred embodiment of the present application, the base station further includes a cleaning component 500;

[0054] The cleaning assembly 500 is disposed inside the box 100 , and includes a cleaning valve and a flushing nozzle. The flushing nozzle is connected to the water supply pipeline 220 . The cleaning valve is used to control the water passage of the flushing nozzle. The flushing nozzle is used to flush the water containing chamber 110 .

[0055] In this embodiment, in order to make the device have a self-cleaning function, a cleaning nozzle is designed, and the cleaning nozzle sprays clean water to clean the interior of the box body 100.

[0056] like Figure 3 As shown, as a preferred embodiment of the present application, the base station further includes a sensing component 800;

[0057] The sensing component 800 is disposed on the side wall of the box 100 and is used to sense the docking status between the base station and the floor cleaning robot.

[0058] In this embodiment, the sensing component 800 is used to enable the base station to sense whether it is correctly docked with the floor cleaning robot. When the docking is completed, operations such as injecting water into the robot are performed.

[0059] As a preferred embodiment of the present application, the base station further includes a control unit;

[0060] The control unit includes a controller and a control panel. The control panel, the water level detector, the drainage pump, the water filling valve 240, the sensing component 800 and the flushing valve are all electrically connected to the controller.

[0061] In this embodiment, in order to improve the intelligence level of the base station, a control unit is also provided inside the base station. The control unit can be connected to the outside world and the robot by wire or wirelessly. The controller can adopt a single-chip microcomputer, etc., and can have a built-in control program.

[0062] As a preferred embodiment of the present application, the method in which the control unit controls the base station to perform a drainage task is:

[0063] Acquire a water level signal from the water level sensor;

[0064] When the water level signal is higher than a first threshold, controlling the drainage pump to start;

[0065] When the water level signal is lower than a second threshold, the flushing timer starts, and the flushing valve is controlled to open;

[0066] When the flushing timer reaches a first flushing time threshold, closing the flushing valve;

[0067] When the flushing timer reaches the second flushing time threshold, the drain pump is turned off.

[0068] In this embodiment, the controller may be built with a variety of control programs and control strategies for water supply and drainage, one of which is a drainage strategy: when the floor scrubbing robot is aligned with the working base station, the robot discharges the sewage, and the sump 120 introduces the sewage into the water holding chamber 110. When the sewage reaches a certain amount, the controller receives a full water signal from the liquid level monitor 300, that is, the liquid level is higher than the first threshold signal, and the drainage pump is started to discharge the sewage through the drainage pipe to the floor drain or sewer, etc. When the sewage discharge is completed, the liquid level is lower than the second threshold. In order to avoid residual sediment in the water holding chamber 110, the internal flushing valve is opened to clean the water holding chamber 110 through the flushing nozzle. After the flushing time reaches the first flushing time threshold, the flushing valve is closed; then the flushing water is pumped out by the drainage pump, and the drainage is completed after the second flushing time threshold, and the drainage pump is closed.

[0069] like Figure 3As shown, as a preferred embodiment of the present application, the base station also includes a drug injection component 700; the drug injection component 700 includes a containing box and an injection head, the containing box is arranged on the outer wall of the box body 100, and the injection head is arranged at the bottom of the containing box, the injection head connects the water containing cavity 110 of the box body 100 and the containing box, and the containing box is provided with scale lines.

[0070] In this embodiment, additives such as disinfectant can be injected into the containing box.

[0071] like Figure 1 As shown, as a preferred embodiment of the present application, the base station further includes a hand washing component 600;

[0072] The hand-washing assembly 600 is disposed on the outer wall of the box body 100 and includes a spray gun and a flexible pipe. The spray gun is connected to the clean water injection end 210 through the flexible pipe.

[0073] In this embodiment, the flexible pipe may be an elastic spiral tube, which is connected to the clean water injection end 210 , and a manual switch is provided on the spray gun so that the spray gun can be used for manual cleaning.

[0074] like Figure 3 As shown, as a preferred embodiment of the present application, the base station further includes a ventilation unit 900;

[0075] The ventilation unit 900 is disposed through the box body 100 to connect the water containing chamber 110 with the outside. The ventilation unit 900 is provided with a ventilation fan.

[0076] In this embodiment, the ventilation unit 900 uses a fan to ventilate the inside and outside of the box 100, so that the air inside and outside the box 100 forms convection.

[0077] As a preferred embodiment of the present application, the water adding valve 240 and the flushing valve are both solenoid valves, and the flushing nozzle is arranged at the top of the water containing chamber 110, and at least one is arranged.

[0078] In this embodiment, the solenoid valve can make the control more convenient. The flushing nozzle is arranged at the top of the water containing chamber 110, and at least one is arranged to make the flushing more thorough.

[0079] As a preferred embodiment of the present application, a filter 270, a constant pressure valve 250 and a flow meter 260 are sequentially arranged between the water supply pipeline 220 and the water adding valve 240, and the flow meter 260 is located on a side close to the water adding valve 240;

[0080] The water adding valve 240 is a three-way valve, and the water adding valve 240 is also connected to an overflow pipe 260 . The water adding valve 240 is also used to control the on-off of the water path between the water adding head 230 and the overflow pipe 260 .

[0081] In this embodiment, if Figure 4 As shown, the water adding valve 240 and the cleaning valve are both arranged in the water circuit downstream of the flow meter 280. The flow meter 280 can be used to measure the total water adding amount of the machine. The filter 270 is used to filter impurities in the pipeline. Since the pressure at the water inlet end may be significantly higher than that at the water outlet, a constant pressure valve 250 is required to control the pressure. Since there is still residual pressure in the pipeline after the water adding head 230 adds water to the robot, the water adding head 230 may overflow. In order to avoid this phenomenon, the water adding valve 240 can be designed as a three-way valve. For example, after closing the water circuit between the water adding head 230 and the water supply pipeline 220, the water circuit between the water adding head 230 and the overflow pipe 260 is opened to avoid overflow.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
