The ultrasonic cleaner uses the high-frequency oscillation signal sent by the ultrasonic generator to make the liquid have a "cavitation effect" and generate a strong shock wave, so as to peel off the dirt layer. It is to convert the sound energy of ultrasonic waves into mechanical kinetic energy through high frequency oscillation, produce countless bubbles on the surface of the object, and continuously blast to achieve the purpose of cleaning. It is to convert the sound energy of ultrasonic waves into mechanical kinetic energy through high-frequency oscillation, produce countless bubbles on the surface of the object, and continuously blast to achieve the purpose of cleaning. In this process, the ultrasonic cavitation phenomenon will cause the cavitation to collapse at the solid-liquid interface, resulting in violent temperature changes and high-pressure impact solids, which will bring physical impact to the entire glasses, and achieve internal crushing of dirt, which will not destroy the external structure and make the product look new.
