The use of "piezoelectric ceramic sheet" ultrasonic generator, 45,000 times per second high-frequency vibration, water in the ultrasonic effect of cavitation effect separates out countless invisible tiny bubbles, small bubbles in the ultrasonic acoustic pressure under the action of rapid expansion and ultimately "explosion ", resulting in close to 1,000 atmospheric pressure of the instantaneous impact of the dirt on the surface of the object is constantly flushed, so that the surface of the dust, bacteria, oil to achieve emulsification, stripping, cleaning up to the micron level of the crevice blind spot. (Vibration frequency directly determines the power of the explosion, ultrasonic explosion formed by the strength of the impact force directly determines the cleaning intensity. 45000Hz high-frequency vibration can bring amazing cleaning effect at the same time will not cause damage to the object.
