Description

Technical Field

[0001] This utility model belongs to the field of automated cleaning equipment technology, and in particular relates to a working base station for a floor cleaning robot. Background Technology

[0002] A floor cleaning robot's work station is a device used by the robot for charging, parking, cleaning, and data exchange during the robot's cleaning tasks.

[0003] The base station of a floor cleaning robot often includes a water system, primarily designed to handle the supply and management of water during the cleaning process. This typically includes a water tank, pipes, valves, and connections to the robot. The specific structure of the water system varies depending on the brand and model.

[0004] Generally, existing robot base station internal water systems include separately designed clean water tanks and wastewater tanks, water supply pipes, valves, and water flow control systems. Each of these separately designed clean water tanks and wastewater tanks requires a separate design and manufacture as an independent base station component, which is then installed inside the base station. This necessitates separate installation and support structures within the workstation, resulting in low material utilization and high costs. Furthermore, the separate design leads to low space utilization and a small internal water tank capacity.

[0005] Therefore, improvements to existing robot base stations are needed. Utility Model Content

[0006] The purpose of this application is to provide a working base station for a floor cleaning robot, which aims to solve the problems of low material utilization, high cost, low internal space utilization, and small internal water tank capacity of existing robot base stations.

[0007] This application embodiment is implemented as follows: a working base station for a floor cleaning robot is provided, the base station comprising:

[0008] The box body has a water-containing cavity at its bottom;

[0009] A water collection tank is provided outside the housing and communicates with the water-containing cavity, for collecting wastewater discharged by the floor cleaning robot and introducing it into the water-containing cavity;

[0010] The water supply assembly includes a clean water injection end, a water supply pipeline, a water inlet head, and a water inlet valve. The clean water injection end is used to inject clean water from outside the device into the water supply pipeline.

[0011] A liquid level monitor is used to detect the liquid level height in the water-containing cavity;

[0012] The drainage assembly, including a drainage pump and a drainage pipe, is used to discharge wastewater from the water-containing chamber to the outside of the device.

[0013] Preferably, the base station further includes a cleaning component;

[0014] The cleaning assembly is located inside the housing and includes a cleaning valve and a rinsing nozzle. The rinsing nozzle is connected to the water supply pipe. The cleaning valve is used to control the water flow of the rinsing nozzle. The rinsing nozzle is used to rinse the water chamber.

[0015] Preferably, the base station further includes sensing components;

[0016] The sensing components are mounted on the side wall of the housing and are used to sense the docking status between the base station and the floor cleaning robot.

[0017] Preferably, the base station further includes a control unit;

[0018] The control unit includes a controller and a control panel. The control panel, water level detector, drain pump, water inlet valve, sensing components, and flushing valve are all electrically connected to the controller.

[0019] Preferably, the base station further includes a drug injection component;

[0020] The drug injection assembly includes a container, a peristaltic pump, and an injection head. The container is disposed on the outer wall of the housing, and the injection head is disposed at the bottom of the container. The injection head connects the water-containing cavity of the housing and the container. The peristaltic pump is used to control the water flow of the injection head. The container is provided with scale lines.

[0021] Preferably, the base station further includes a handwashing component;

[0022] The handwashing assembly is installed on the outer wall of the box and includes a spray gun and a flexible pipe. The spray gun is connected to the clean water injection end through the flexible pipe.

[0023] Preferably, the base station further includes a ventilation unit;

[0026] Preferably, a filter, a constant pressure valve, and a flow meter are sequentially arranged between the water supply pipeline and the water inlet valve, with the flow meter located on the side closer to the water inlet valve;

[0027] The water filling valve is a three-way valve, and the water filling valve is also connected to an overflow pipe. The water filling valve is also used to control the water flow between the water filling head and the overflow pipe.

[0028] The working base station for a floor cleaning robot provided in this application has the following key advantages: Compared to existing robot base stations that use separate drawer-type independent water tanks, the shell of the robot working base station in this application is used for water storage itself, eliminating the need for separate clean water tanks and wastewater tanks.

[0038] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0039] like Figure 1 and Figure 2 The image shown is a three-dimensional structural view of a working base station for a floor cleaning robot according to an embodiment of this application. The base station includes:

[0040] The box body 100 has a water-containing cavity 110 at its bottom;

[0041] A water collection tank 120 is disposed outside the housing 100 and communicates with the water holding chamber 110, for collecting wastewater discharged by the floor cleaning robot and introducing it into the water holding chamber 110;

[0042] The water supply assembly 200 includes a clean water injection end 210, a water supply pipe 220, a water inlet head 230, and a water inlet valve 240. The clean water injection end 210 is used to inject clean water from outside the device into the water supply pipe 220. The water inlet head 230 is connected to the water supply pipe 220 and is used to inject clean water into the floor cleaning robot. The water inlet valve 240 is used to control the on / off of the water supply to the water inlet head 230.

[0043] The liquid level monitor 300 is used to detect the liquid level height in the water-containing cavity 110;

[0044] The drainage assembly 400 includes a drainage pump and a drainage pipe for discharging wastewater from the water-containing chamber 110 to the outside of the device.

[0045] In this embodiment, the housing 100 is a shell structure, and the bottom of the shell forms a water-holding space, namely a water-receiving cavity 110. Simultaneously, a water guide channel, namely a water collection channel 120, is provided on the housing 100. This channel can be located outside the housing 100 and its function is to collect wastewater discharged by the floor cleaning robot and guide it into the water-receiving cavity 110 for collection. Figure 4 As shown, the clean water injection end 210 of the water supply component 200 can be connected to an external water pipe to connect a clean water source outside the base station device to the water supply pipe 220. The water supply pipe 220 and the water inlet valve 240 can both be installed inside the housing 100. Two clean water injection ends 210 can be installed at opposite ends of the housing 100, both of which can be connected to the water supply pipe 220, allowing users to install and select according to their specific needs. Similarly, the housing 100 is equipped with two drainage ports. The sewage ports can be used to connect longer sewage pipes to floor drains or sewers. The sewage ports are arranged on both the left and right sides, allowing the drainage pipe to be connected to either end as needed.

[0046] The key advantage of this application's embodiment is that, compared to existing robot base stations using separate drawer-type independent water tanks, the robot work base station's casing in this application is used for water storage itself, eliminating the need for separate clean water and wastewater tanks and removing any internal mounting structures. This significantly reduces costs and increases the water tank's capacity. The simple outer shell structure avoids installation and maintenance steps. In this application, the base station's water supply component 200 directly injects external clean water into the robot through the water supply pipe 220, eliminating the need for a separate clean water container inside the base station. This provides more space for the wastewater tank, saving manufacturing costs and increasing the base station's integration level. It also enables the base station to quickly recover wastewater from inside the robot in a short time, improving operational efficiency.

[0047] like Figure 3 As shown, in a preferred embodiment of this application, the base station further includes a cleaning component 500;

[0048] The cleaning component 500 is disposed inside the housing 100 and includes a cleaning valve and a rinsing nozzle. The rinsing nozzle is connected to the water supply pipe 220. The cleaning valve is used to control the water flow of the rinsing nozzle. The rinsing nozzle is used to rinse the water chamber 110.

[0049] In this embodiment, in order to enable the device to have a self-cleaning function, a cleaning nozzle is designed to spray clean water to clean the inside of the housing 100.

[0050] like Figure 3 As shown, in a preferred embodiment of this application, the base station further includes a sensing component 800;

[0051] The sensing component 800 is disposed on the side wall of the housing 100 and is used to sense the docking status between the base station and the floor cleaning robot.

[0052] In this embodiment, the sensing component 800 is used to enable the base station to sense whether it has correctly docked with the floor cleaning robot. Once docking is complete, it performs operations such as filling the robot's interior with water.

[0053] In a preferred embodiment of this application, the base station further includes a control unit;

[0054] The control unit includes a controller and a control panel. The control panel, water level detector, drain pump, water inlet valve 240, sensing component 800, and flushing valve are all electrically connected to the controller.

[0055] In this embodiment, in order to improve the intelligence level of the base station, a control unit is also set up inside the base station. The control unit can be connected to the outside world and robots via wired or wireless means. The controller can be a microcontroller or the like, and can have a built-in control program.

[0056] In a preferred embodiment of this application, the method by which the control unit controls the base station to perform the drainage task is as follows:

[0057] Acquire the water level signal from the water level sensor;

[0058] When the water level signal is higher than the first threshold, the drainage pump is controlled to start.

[0059] When the water level signal is lower than the second threshold, the flushing timer starts and the flushing valve is opened.

[0060] Once the flushing timer reaches the first flushing time threshold, the flushing valve is closed.

[0061] Once the flushing timer reaches the second flushing time threshold, the drain pump is turned off.

[0062] In this embodiment, the controller can have multiple built-in control programs and water supply and drainage control strategies. One drainage strategy is as follows: When the floor cleaning robot aligns with the work base station, the robot discharges wastewater, and the collection tank 120 introduces the wastewater into the water storage chamber 110. When the wastewater reaches a certain amount, the controller receives a full water signal from the liquid level monitor 300, indicating that the liquid level is higher than the first threshold signal. The drainage pump then starts to discharge the wastewater through the drainage pipe to the floor drain or sewer. When the sewage discharge is finished, the liquid level is lower than the second threshold. To avoid residual mud and sand in the water storage chamber 110, the internal flushing valve opens to clean the water storage 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. After the second flushing time threshold is reached, the drainage is completed, and the drainage pump is turned off.

[0063] like Figure 3 As shown in the preferred embodiment of this application, the base station further includes a drug injection component 700; the drug injection component 700 includes a container, a peristaltic pump and an injection head, the container is disposed on the outer wall of the housing 100, the injection head is disposed at the bottom of the container, the injection head connects the water-containing cavity 110 of the housing 100 and the container, the peristaltic pump is used to control the water flow of the injection head, and the container is provided with scale lines.

[0064] In this embodiment, the container can be filled with additives such as disinfectant, and the peristaltic pump is connected to the controller to control the amount of medicine injected.

[0065] like Figure 1As shown, in a preferred embodiment of this application, the base station further includes a handwashing component 600;

[0066] The handwashing assembly 600 is disposed on the outer wall of the housing 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.

[0067] In this embodiment, the flexible pipe can be an elastic spiral pipe, which is connected to the clean water injection end 210. The spray gun has a manual switch, which can be used to perform manual cleaning.

[0068] like Figure 3 As shown, in a preferred embodiment of this application, the base station further includes a ventilation unit 900;

[0069] The ventilation unit 900 is disposed through the housing 100 and is used to connect the water-containing cavity 110 with the outside. The ventilation unit 900 is equipped with an exhaust fan.

[0070] In this embodiment, the ventilation unit 900 uses a fan to ventilate the inside and outside, so that the air inside and outside the box 100 can form convection.

[0071] In a preferred embodiment of this application, both the water inlet valve 240 and the flushing valve are solenoid valves, and the flushing nozzle is located at the top of the water-containing chamber 110, and at least one nozzle is provided.

[0072] In this embodiment, a solenoid valve makes control more convenient. A flushing nozzle is located at the top of the water-containing chamber 110, and at least one nozzle is provided to ensure more thorough flushing.

[0073] In a preferred embodiment of this application, a filter 270, a constant pressure valve 250, and a flow meter 260 are sequentially arranged between the water supply pipe 220 and the water supply valve 240, with the flow meter 260 located on the side closer to the water supply valve 240.

[0074] The water filling valve 240 is a three-way valve. The water filling valve 240 is also connected to an overflow pipe 260. The water filling valve 240 is also used to control the water flow between the water filling head 230 and the overflow pipe 260.

[0075] In this embodiment, as Figure 4As shown, both the water inlet valve 240 and the cleaning valve are located downstream of the flow meter 280. The flow meter 280 is used to measure the total water volume added to the machine. The filter 270 is used to filter impurities in the pipeline. Since the pressure at the inlet may be significantly higher than that at the outlet, a constant pressure valve 250 is needed to control the pressure. Because there is still residual pressure in the pipeline after the water inlet head 230 adds water to the robot, it may cause overflow. To avoid this phenomenon, the water inlet valve 240 can be designed as a three-way valve. For example, after closing the water path between the water inlet head 230 and the water supply pipeline 220, the water path between the water inlet head 230 and the overflow pipe 260 can be opened to prevent overflow.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
