The high-frequency oscillating signal generated by the ultrasonic signal generator (power source) is converted into a high-frequency mechanical oscillation by the transducer (vibrator) and propagated into the liquid.Ultrasound radiates densely in liquid and generates tens of thousands of tiny bubbles.These bubbles form and grow in the negative pressure zone during propagation.It closes rapidly in the positive pressure,In this process, which is called “cavitation effect”, the bubble closure can form thousands of instantaneous high pressure of atmospheric pressure . The continuous high pressure is like countless small “explosions” continuously impacting on the surface of the object, so that the dirt in the surface and crevices of the object can be peeled off quickly, so as to achieve the purpose of cleaning.
