Therefore, ultrasonic cleaning machines often require a large investment, and the ultrasonic generator has the problem of power reduction over time. Summary of the invention

When the compressed air enters the cleaning tank, it generates water flow disturbance in the cleaning liquid. Gases in different directions cause the cleaning liquid to have a greater impact force and generate a large number of bubbles at the same time. The combined effect of these bubbles impacts and peels off the oil stains on the surface of the parts, and cooperates with the saponification effect of the cleaning liquid on the oil stains to improve the cleaning effect of the parts.
