Refrigerator humidification

The high-frequency vibration of the piezoelectric ceramic vibrator is used to drive the metal diaphragm with micropores to vibrate, and the liquid is squeezed out of the micro-holes to open the molecular link, thereby achieving atomization of the liquid. The module can work at low water temperatures and uses automatic frequency matching technology to ensure stable atomization.
