Intelligent atomising head integrates ultrasonic atomising piece and circuit board, the circuit drives the ultrasonic transducer device to produce high-frequency axial mechanical deformation, so that cavitation occurs on the surface of the liquid, breaking up the water molecules into micro-molecules, and rapidly atomising and volatilising. The module can be externally connected to the fan, water level sensor and knob switch, but also with a variety of extended function interface, suitable for a variety of flexible and diverse machine design. In addition, the product supports a variety of communication protocols such as UARI, GPIO, etc., which can be applied to the IOT system, featuring high efficiency, stability, safety and digitalisation.
