Ultrasonic humidification function

In order to be able to use ultrasonic waves for air humidification, electrical energy has to be converted into mechanical energy. This takes place in the piezoelectric transduce (also called transducer and oscillator).
Vibrations arise as a result of a pressure change. Repeated increases and decreases in pressure produce different sound waves. The frequencies 16 - 20,000 Hz are audible to the human ear. All higher frequencies are called ultrasound.
A vibration unit thus consists of the resonance circuit in which the high frequency of ~ 1.7 MHz is generated and the piezoelectric transducer to convert the electrical frequency into a proportional, mechanical oscillation.

The piezoceramic transducers are mounted on the bottom of the water reservoir of the humidifier. Upon excitation of the transducer directs water ultrasonic vibrations to the interface between water and air.

The constant compress / decompress the water column above the transformer causes cavitation near the water surface. This will form Crossed capillary waves that make up the wave crest smallest mist droplets (aerosols) solve.
The aerosols have a very small diameter (~ 0.001-0.005 mm). You will be discharged by the airflow in the humidifier and mix quickly with the ambient air.
