Ultrasonic cavitation is the most dominant mechanism of ultrasonic cleaning. Part of the air is dissolved in the liquid and these micro-bubbles are present in the liquid and are called cavitation nuclei. When ultrasonic wave is generated, the liquid is driven to vibrate. During the movement of these liquids, more microbubbles are incorporated. The density of the liquid changes when it vibrates. Positive pressure is generated on the cavitation nuclei at the place where the liquid density is high, and negative pressure is generated on the cavitation nuclei at the place where the liquid density is low. When the sound pressure reaches a certain value, the cavitation nuclei can be expanded outwards rapidly to form larger bubbles when being subjected to negative pressure, can be closed rapidly under the action of positive pressure, generate huge impact and local pressure, and the local pressure during closing can reach thousands of atmospheric pressures according to estimation. The great pressure generated during closing can impact the insoluble oil stain to make it fall off from the tableware.
