As described above, the control circuit of the atomizing humidifier of the present invention outputs the PWM square wave with constant frequency but increased voltage after transforming the voltage through the transformer T, and then transmits the transformed PWM square wave to the piezoelectric ceramic plate disposed on the atomizing plate unit 40, so as to generate the high frequency resonance, and the energy of the high frequency resonance causes the liquid attached to the piezoelectric film to generate the high frequency oscillation, thereby scattering the liquid structure and generating the naturally flowing mist. The structural design does not need to heat liquid or add any reagent, and compared with heating atomization, the energy can be saved by more than 95%. The integrated circuit U of the control unit 20 can set the atomization time and the atomization mode of continuous atomization and intermittent atomization, thereby being convenient and practical and saving energy. The inner wall of the housing 60 of the atomizing humidifier is provided with a first fixing groove 64 and a second fixing groove 65, the side surface of the top cover 90 is provided with a stopping portion 92 in an outward protruding manner, the PCB 70 and the stopping portion 92 of the top cover 90 are respectively clamped in the first fixing groove 64 and the second fixing groove 65, and the housing 60 includes a first housing 61 and a second housing 62 clamped on the first housing 61. The atomizing humidifier adopts a buckle mechanism and has the advantages of simple structure, small volume, low cost, convenient maintenance and the like.
The above-mentioned embodiments only represent the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
