The piezoelectric ceramic plate (commonly known as ultrasonic atomizer) is installed at the bottom of a water container, and a driving control circuit generates a driving voltage consistent with the resonant frequency of the atomizer, and the atomizer will produce oscillating energy.

Vibration energy in the water spread along a direction perpendicular to the atomization surface, under the condition of appropriate depth, energy transmission shaft surface uplift a spout, the front end of the concentrated water column and the occurrence of a large number of small tensile wave, greatly reduce the surface tension of the uplift of the water, the water by capillary wave wavelength divided into many small regions, each region as mutually binding independently become a particles, a distributed in the air to form fog effect, this is the principle of ultrasonic atomization.

Because the working frequency of piezoelectric ceramic sheet is in the range of ultrasonic frequency, we call this kind of atomization as ultrasonic atomization, which is called ultrasonic atomization for short.

Ultrasonic atomizer is the component that uses ultrasonic atomization principle to work, because it is usually used as the core part of humidifying complete machine product, it is also called ultrasonic atomization accessories, atomization accessories for short.
