In one embodiment, the baffle 25 and the main body 210 are integrally formed, making the connection between the baffle 25 and the main body 210 more firm, reducing the possibility of the baffle 25 loosening due to long-term use or vibration, and at the same time reducing the manufacturing cost and installation complexity.

[0087] Refer to Figure 1 as shown in

[0088] In some embodiments, the controller is connected to the first filter element 45 and the second filter element 46, and the controller can control the working states of the first filter element 45 and the second filter element 46 according to the filtering requirements.

[0089] Refer to Figure 1 as shown in

[0090] In this embodiment, the recycling and filtering component 4 is located above the liquid storage component 1, effectively increasing the gravitational difference between the recycling and filtering component 4 and the liquid storage component 1, thereby ensuring the stability and reliability of the flow of the cleaning liquid. It can be understood that in other embodiments, the positions of the components in the box body 6 can be set as needed.

[0091] In a specific application scenario, during operation, the controller controls the second solenoid valve 32 and the pressure regulating valve 31 to open, and at the same time closes the third solenoid valve 44 and the two-way valve 5 to ensure the smooth progress of the liquid spraying process. At this time, the cleaning liquid in the first container 11 is pressurized by the second solenoid valve 32 and the pressure regulating valve 31, flows from the first liquid outlet 112 through the first pipeline 12 into the third liquid inlet 210b, and then flows out along the brush 23 from the third liquid outlet 211a through the fluid channel 220a to complete the liquid spraying operation. Among them, the cleaning liquid flowing out along the brush 23 will drip into the liquid return tank 210a;

[0092] After the liquid spraying is completed, the controller controls the second solenoid valve 32 to close, and the third solenoid valve 44, the second vacuum generator 43, the first vacuum generator 10, the first solenoid valve 19 and the two-way valve 5 to open. The first vacuum generator 10 evacuates air through the pressurizing port 114, and the second vacuum generator 43 evacuates air through the vacuum port 413 of the second container 41, so that the same negative pressure is generated in the first container 11 and the second container 41. Under the action of the negative pressure, the cleaning liquid in the liquid return tank 210a is preliminarily filtered by the second filter element 46 and then enters the second container 41 from the second liquid inlet 411 through the fourth pipeline 42, and then undergoes deep filtration by the first filter element 45;

[0093] Then the controller controls both the second solenoid valve 32 and the third solenoid valve 44 to close, and the first solenoid valve 19 and the two-way valve 5 remain open. At this time, the first container 11 is still in a negative pressure state, and the second container 41 returns to normal pressure and forms a pressure difference with the first container 11. The cleaning liquid deeply filtered by the second filter element 46 flows from the second liquid outlet 412 through the second pipeline 13 to the first liquid return port 113 and then flows into the first container 11, realizing the recycling and reuse of the cleaning liquid.

[0094] When the second solenoid valve 32 is opened, a new liquid spraying cycle starts. At this time, the third solenoid valve 44 and the two-way valve 5 are closed again to prevent the cleaning liquid from flowing back.

[0095] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
