The connection relationship of each component is as follows:

[0017] The linear motion module 2 is vertically mounted on the front back plate of the main frame 1, and the installation method is that the linear motion module 2 can be controlled to move up and down. The air compressor 7, water pump 8, water tank 9, and control system 10 are installed on the multi-layer platform at the rear of the main frame 1, where the air compressor 7 is placed on the bottom layer, the water pump 8 and water tank 9 are placed on the middle layer, and the control system 10 is placed on the upper layer. The connection form is as follows Figure 4 As shown, the water circuit connection form is that the water tank 9 is connected to the water pump 8 through the pipeline 5, and then connected to the solenoid valve through the pipeline 5, and then connected to the one-way valve through the pipeline 5, and then connected to the multi-way joint through the pipeline 5, and finally connected to the fan-shaped nozzle 4 through the pipeline 5. The gas circuit connection form is that the air compressor 7 is connected to the solenoid valve through the pipeline 5, and then connected to the one-way valve through the pipeline 5, and then connected to the multi-way joint through the pipeline 5, and finally connected to the fan-shaped nozzle through the pipeline 5. The water tank 9 is the liquid source, and the water tank 9 contains three separated liquids, namely: detergent, pure water, and anhydrous ethanol. The water pump 8 is the liquid circuit power source, the air compressor 7 is the gas circuit power source, the pipeline 5 is the liquid and gas passage, the solenoid valve controls the on-off of the passage, the one-way valve prevents liquid and gas from flowing through, and the multi-way joint connects the gas and liquid two-phase input and the output of multiple fan-shaped nozzles 4. The mirror 3 to be cleaned is mounted in front of the fan-shaped nozzle 4, and can also be installed vertically in front of the equipment. The fan-shaped nozzles 4 are installed side by side on the linear motion module 2, such as Figure 2 As shown, the fan-shaped nozzles 4 are arranged horizontally and equidistantly at a specific distance, so that the jet flow rate at each point on the mirror surface to be cleaned is consistent. The control system 10 is used to control the up and down movement of the linear motion module 2, the opening and closing of the solenoid valve, the opening and closing of the water pump power supply, and the liquid switching and low liquid level detection of the water tank 9. The buttons in the control system 10 control the cleaning equipment to perform detergent solution washing, pure water washing, anhydrous ethanol washing and gas drying in sequence, so as to obtain a clean mirror surface.

[0018] In one embodiment, the linear motion module 2 can be a synchronous belt linear guide slide, which is driven by a servo motor or a stepper motor to slide on the guide rail, and its movement direction, speed and stroke are adjusted by the control system 10, and the guide rail is fixed to the front back plate of the main frame 1 by screws.

[0019] The fan-shaped nozzle 4 can be installed on the linear motion module 2 by fixing an aluminum plate with a transverse long groove on the slider by screws, and installing the fan-shaped nozzles 4 in parallel in the groove of the aluminum plate. The installation spacing can be adjusted as needed.

[0020] Universal wheels 6 are installed under the main frame 1, so the whole set of equipment can be moved conveniently, and the only external interface is a 220V AC power plug.

[0021] In one embodiment, a plurality of fan-shaped nozzles are driven by the linear motion module to move longitudinally, and the cleaning area is a rectangle, such as Figure 3 As shown, the size of the cleaning area can be adjusted by adjusting the number of fan-shaped nozzles and the movement stroke. Through the specific fan-shaped nozzle arrangement distance and deflection angle, the jets of each fan-shaped nozzle do not interfere with each other, and the cleaning effect is uniform in the entire cleaning range. In one example, the fan-shaped nozzle 4 is installed with a small rotation angle (such as 2°) to stagger the fan-shaped jets by one phase to avoid interference between the jets of adjacent fan-shaped nozzles 4.

[0022] In one embodiment, a water pump 8 and an air compressor 7 are used together as cleaning power, and a high-pressure gas source and a low-pressure liquid source are mixed near the inlet of the fan-shaped nozzle.

One-way valves are respectively provided in the liquid circuit and the gas circuit to prevent cross-circuiting.

[0023] In one embodiment, filters are provided in both the liquid circuit and the gas circuit to control the cleanliness of the equipment and prevent impurities from damaging the cleaned surface.

The cleaning button is used for cleaning control, and the control system 10 controls the on and off of the solenoid valve and the relay according to the button command, wherein the relay controls the on and off of the water pump power supply; the water tank 9 includes a liquid level sensor, and the feedback control system 10 gives a prompt when the liquid level is lower than the specified value. The control system 10 is powered by a 24V DC power supply, and the 24V DC power supply and the air compressor 7 are powered by 220V AC power, and the remaining electrical equipment is powered by the control system.

[0025] In one embodiment, a pressure gauge and a flow meter may be installed at any position in the pipeline 5 to monitor the cleaning status, and the monitoring objects include the outlet of the water pump 8, the outlet of the air compressor 7, the inlet of the fan-shaped nozzle 4, etc.; a heater may be installed in the pipeline 5 to heat the jet; a rangefinder may be installed at the installation position of the fan-shaped nozzle 4 to determine the cleaning target distance and avoid collision; a dust-free cloth or other wiping tools may be installed near the fan-shaped nozzle 4 to wipe immediately after spraying.

[0026] According to an embodiment of the present invention, a portable automatic mirror cleaning method is provided, which can fully clean the mirror without damaging the mirror, and there is no residue after cleaning; the method has a total of 4 cleaning processes, including detergent solution rinsing, pure water rinsing, anhydrous ethanol rinsing and gas drying, and ether, acetone and other solutions can be added as needed. The method includes the following steps: the control system 10 issues an instruction to rinse the mirror 3 to be cleaned with detergent solution, pure water, and anhydrous ethanol respectively; after the cleaning action is completed, the control system 10 issues a drying instruction to perform gas drying on the mirror 3 to be cleaned.

[0027] In summary, the device has the advantages of portability, low cleaning cost, high degree of automation, fast cleaning speed, no damage to the cleaning object, scalable structure, and no restrictions on the size of the mirror.
