principle of “Ultrasonic Atomization”. A piezoelectric transducer immersed in a water bed, converts a high frequency, electronic signal into a high-frequency mechanical oscillation.
The benefits of ultrasonic humidifiers
- They are very good at humidifying the air. …
- Ultrasonic humidifiers can be made extremely small and compact because the humidifying mechanism is so simple. …
- The vibration of an ultrasonic humidifier is much quieter than the fan of an evaporative humidifier
They produce a warm or cool mist by using a metal diaphragm vibrating at high frequency. The sound vibrations propel moisture into the air. … The mist is almost immediately absorbed into the air. Because this type of humidifier does not use a fan, it is very quiet when operating
This forms an extremely fine mist of droplets about1-.45 micron in diameter, that is quickly evaporated into the airflow.
