Gated cleaning principle of ultrasonic cleaning machine ultrasonic metal: the volatility is more than human hearing audio conduction in the liquid when conducting sound waves in the cleaning solution, because the acoustic longitudinal wave is a longitudinal wave would boost the liquid medium pressure changes arising from countless tiny vacuum small bubbles, called the "hole effect" when the vacuum small bubbles bursting under pressure, will have its strong impulse energy, can be attached to objects in the blind spot of dirt scattered and enhance cleaning effect of cleaning, since high frequency ultrasonic wave length, penetration, and therefore have hidden objects slit or complex structures, can achieve amazing cleaning effect.
