In the implementation process of providing an embodiment of pressurizing a water tank by using a gas source to supply gas to spray clear water, the inventor of the application finds that the capacity of a clear water tank equipped in a common base station is generally larger, and if the gas is input into the large clear water tank by using the gas source, the water yield and/or the water outlet rate of the water tank are not easy to control. In particular for a base station cleaning mop, it is often desirable to have a controllable water spray volume and/or water spray rate.

Referring to fig. 1a, fig. 1b, and fig. 2, a cleaning base station according to an embodiment of the present utility model includes:

the base station body is provided with a cleaning system, and the cleaning system is configured to clean the to-be-cleaned piece;

the air source system is communicated with the cache box 100 through an air port 103 and is used for supplying air into the cache box 100 to apply positive pressure so as to enable liquid in the cache box 100 to be sprayed out through the water outlet 102;

the volume of the cache box 100 is less than or equal to a preset value, so that the cache box 100 at least comprises a first state and a second state; wherein in the first state, the liquid in the buffer tank 100 substantially fills the buffer tank 100; the cleaning system performs a cleaning task to switch the cache tank 100 from the first state to the second state in which the cache tank 100 is substantially empty of liquid.

The cleaning base station according to the present embodiment is a base station for nursing a cleaning robot, and the nursing type is, for example, cleaning nursing or the like. Specifically, the cleaning base station mainly includes a base station body, a buffer tank 100, a gas source system and other structures, the base station body is provided with a cleaning system for cleaning a cleaning member, wherein the cleaning member may be a cleaning robot or a cleaning member of the cleaning base station, and exemplary cleaning members of the cleaning robot may be a rolling brush, a sweeping brush, a moving wheel, a universal wheel and the like, while cleaning members of the cleaning base station may be cleaning base stations, cleaning tanks for cleaning the cleaning robot and the like, and the cleaning system may spray water toward the cleaning tanks of the base station to clean the cleaning tanks. The cleaning system can be composed of a spray head assembly and a water pipe according to actual conditions.

The buffer box 100 is connected with the base station body, optionally, the buffer box 100 is detachably arranged on the base station body, and the connection mode can adopt various modes such as buckle connection, screw connection and the like. Also, the buffer box 100 may be provided inside or outside the base station body, which is not limited. Wherein, the water inlet 101 of the buffer tank 100 is communicated with a water source, the water outlet 102 is communicated with a cleaning system, and the air port 103 is communicated with an air source system. The buffer tank 100 is used to buffer the cleaning water of the cleaning system and supply the cleaning system with liquid when performing a cleaning task. Specifically, when the cleaning system needs to perform a cleaning task, water from a water source enters the buffer tank 100 through the water inlet 101 for buffering, and after buffering is completed, the air source system supplies air into the buffer tank 100 to apply positive pressure, and liquid in the buffer tank 100 is sprayed out through the water outlet 102 under the action of air pressure to supply liquid for the cleaning system. The base station may be provided with a water storage tank as shown in fig. 1a, and water is supplied from the water storage tank as a water source, or may be provided with a tap, a water supply pipeline, etc. outside the base station as a water source, as shown in fig. 1b, which may be set by a person skilled in the art according to practical situations. Optionally, the air source system includes an air pump, and an air flow pipeline is arranged between an air outlet end of the air pump and an air port 103 of the cache box 100 to supply air to the cache box 100.

Further, the volume of the cache box 100 is smaller than or equal to a preset value, so that the cache box 100 at least includes a first state and a second state, wherein the preset value is set according to practical situations, such as 300ml. The volume of the buffer bin 100 may be designed to be between 200ml and 300ml, and in one embodiment, the volume of the buffer bin 100 is 250ml.

In the first state, the buffer container 100 is substantially filled with the liquid, and the buffer container 100 may be completely filled or slightly filled, and in this embodiment, "substantially filled" is defined as that the error of the liquid separation and filling in the container is within 50ml, for example, when the volume of the buffer container 100 is 250ml, and the volume of the liquid in the container is greater than or equal to 200ml, which is considered to be substantially filled in the buffer container 100. In the second state, the liquid in the buffer tank 100 is substantially drained, and the substantially drained may be completely drained, or may be drained slightly, where Xu Yuliu is a difference between the draining and the draining, and in this embodiment, the substantially drained refers to that the liquid in the tank is within 20ml, for example, when the volume of the buffer tank 100 is 250ml, and in the second state, the liquid in the buffer tank 100 is substantially drained when the volume of the remaining liquid in the tank is less than or equal to 20 ml. After the cleaning system performs a cleaning task, the cache box 100 is switched from the first state to the second state. And the cleaning system is correspondingly provided with water inlet and water spraying for one time. The primary cleaning task described in the embodiment of the present application refers to a water spraying task corresponding to a preset duration of primary water spraying, where the preset duration is set according to an actual situation. For example, when the water consumption of the cleaning system is required for each cleaning task of the cache tank 100, the liquid in the cache tank 100 is drained after the cleaning system performs one cleaning task.

According to the cleaning base station provided by the embodiment of the utility model, the spraying of the cleaning water in the water tank is controlled in a pneumatic mode, and the water does not pass through the pump in a pneumatic driving mode, so that the pump is not easy to be blocked. Moreover, the buffer tank 100 buffers the cleaning water of the cleaning system on the base station body, the volume of the buffer tank 100 is smaller than or equal to a preset value, when the cleaning system of the base station body executes a cleaning task once, the buffer tank 100 is switched from a first state in which the liquid in the tank is basically full to a second state in which the liquid in the tank is basically empty, namely, the buffer tank 100 with small volume buffers the water of the cleaning task once, when the air source system supplies air in the buffer tank 100 with small volume to apply positive pressure, compared with the air supply in a large water tank, the water tank with small volume can control the water yield and the water outlet rate more easily, so that cleaning water spraying is easy to control.

The volume of the buffer tank 100 may be approximately determined according to the air pump flow rate of the air source system, and if the volume of the buffer tank 100 is excessively large, the volume is not matched with the air pump flow rate. In some embodiments, the inventor has found through experimental verification that the volume of the buffer tank 100 is between 200ml and 300ml, so that the water spraying speed is faster and the water spraying is controllable while the flow of the air pump is better matched.

In some embodiments, referring to fig. 1a, 1b and 2, the air supply system is further configured to draw air from the cache tank 100 through the air port 103 to create a negative pressure within the cache tank 100 such that the water supply supplies liquid to the cache tank 100 through the water inlet 101.

In this embodiment, when the cleaning system performs a cleaning task, the air source system pumps air from the cache box 100 through the air port 103 to form a negative pressure in the cache box 100, and under the action of the negative pressure, the water source supplies liquid to the cache box 100 through the water inlet 101. Optionally, the air source system includes an air pump, and an air outlet end and an air inlet end of the air pump may be connected to the air port 103 of the buffer tank 100 through an air flow pipeline, and an air path switching component, such as an air exchange valve, may be disposed in the air flow pipeline. The air passage switching assembly is used for switching air passages, and the air source system can supply air into the cache box 100 through the air opening 103 to apply positive pressure or suck air from the cache box 100 to form negative pressure.

In some embodiments, referring to fig. 3-6, the buffer tank 100 is provided with a closure assembly 10, the closure assembly 10 including a closed state closing the gas port 103, and an open state leaving the gas port 103;

wherein, when the liquid level in the buffer tank 100 is smaller than the preset limit liquid level value, the plugging assembly 10 is in an open state; when the liquid level in the buffer tank 100 is greater than or equal to the preset limit liquid level value, the plugging assembly 10 is in a plugged state.

When the liquid level in the buffer tank 100 is smaller than the preset limit liquid level value, the plugging assembly 10 is separated from the air port 103 and is in an open state. In the open state, the air source system can supply air into the cache box 100 through the air port 103 to apply positive pressure liquid discharge or suck air from the cache box 100 to form negative pressure liquid inlet. When the liquid level in the buffer tank 100 is greater than or equal to the preset limit liquid level value, the blocking assembly 10 blocks the air port 103 and is in a blocking state. In the blocking state, the air source system cannot pump air from the cache box 100 through the air port 103, the cache box 100 cannot feed liquid, and the liquid in the cache box 100 cannot enter the air path through the air port 103, so that the air source (such as an air pump) is protected.

In some embodiments, referring to fig. 3-6, the occlusion assembly 10 may include:

the floating piece 11 is movably arranged in the buffer storage box 100, and the floating piece 11 can be lifted along with the liquid level in the buffer storage box 100 so as to switch the plugging assembly 10 between a plugging state and an opening state;

a blocking member 12 connected to the float member 11 and for blocking or opening the gas port 103;

when the liquid level in the buffer tank 100 rises, the floating piece 11 floats upwards to drive the plugging piece 12 to move towards the air port 103; when the liquid level in the buffer tank 100 drops, the float 11 falls to drive the blocking member 12 to move away from the air port 103.

In this embodiment, the plugging assembly 10 includes a floating member 11 and a plugging member 12, where the plugging member 12 is adapted to the air port 103 for plugging or opening the air port 103. The floating member 11 is used for lifting along with the liquid level in the buffer tank 100, so as to drive the blocking member 12 to move up and down. The external structure and the material of the floating member 11 are not limited, and are set according to actual conditions. Optionally, the air port 103 is located at the upper portion of the buffer tank 100, and the blocking member 12 is located at the upper end of the float member 11 and faces the air port 103.

When the air source system is used for exhausting air from the cache box 100 through the air port 103, negative pressure is formed in the cache box 100, under the action of the negative pressure, water source supplies liquid to the cache box 100 through the water inlet 101, the liquid level in the cache box 100 gradually rises, and then the floating piece 11 floats upwards to drive the plugging piece 12 to move towards the air port 103, and when the cache box 100 is basically full of the liquid in the cache box 100, the plugging piece 12 rises to automatically plug the air port 103.

When the air source system supplies air into the buffer tank 100 through the air port 103, positive pressure is formed in the buffer tank 100, under the action of the positive pressure, liquid in the buffer tank 100 is discharged through the water outlet 102, the liquid level in the buffer tank 100 gradually drops, and then the floating piece 11 drops to drive the plugging piece 12 to move away from the air port 103.

the receiving piece 200 is arranged on the buffer tank 100, and the receiving piece 200 is positioned below the floating piece 11 and is used for limiting the limit descending position of the floating piece 11.

When the liquid level in the buffer tank 100 reaches the position of the receiving member 200 and continuously rises during the liquid feeding process of the buffer tank 100, the floating member 11 rises and breaks away from the receiving member 200 under the buoyancy of the liquid.

As the liquid level in the buffer tank 100 rises or falls, the closure assembly 10 then rises or falls along the mounting cavity 110 a. Wherein, the wall of the installation cavity 110a limits the movement of the floating piece 11 of the plugging assembly 10 in the horizontal direction, has a guiding function on the lifting movement of the floating piece 11 of the plugging assembly 10, and can enable the plugging piece 12 of the plugging assembly 10 to be inserted in alignment with the air port 103. Alternatively, the mounting part 110 protrudes from the upper portion of the buffer tank 100.

Of course, the receiving member 200 and the mounting portion 110 may be integrally formed, or separately formed and fixed together, and the receiving member 200 may be located below the mounting portion 110, so that the plugging assembly 10 moves in the space enclosed by the receiving member 200 and the mounting portion 110.
