At the moment, the liquid storage tank and the connecting pipe can also be replaced by a liquid inlet pipe, and the cleaning solvent is directly supplied into the cleaning tank from the outside through the liquid inlet pipe.

The liquid level sensor detects whether the cleaning solvent reaches the liquid level position of the cleaning tank, so that the dust blocking member can be completely immersed in the cleaning solvent.

In one embodiment, the bottom of the cleaning tank is further provided with a drain valve, and after the step S20 of starting the ultrasonic vibrator and cleaning the dust blocking member, the cleaning method further comprises:

and step S21, controlling the drain valve to open and discharging the cleaning solvent.

Specifically, after the ultrasonic vibrator finishes cleaning the dirt of the dust blocking member, various dirt is floated or dissolved in the cleaning solvent and needs to be discharged out of the cleaning tank through the drain valve, at this time, the drain valve is opened through the control host, and the cleaned cleaning solvent is discharged out of the cleaning tank, so that the next cleaning of the dust blocking member in the optical equipment is carried out.
