How to choose a piezoelectric disc for a humidifier.
Ultrasonic humidifier principle
The water storage tank, power supply, water level monitoring circuit, oscillation circuit, fog output control circuit, and atomization piece make up a home ultrasonic humidifier. The atomization piece serves as the device’s primary function. To comprehend the operation of an ultrasonic humidifier, that is, the operation of the atomization sheet.
This atomization component is usually spherical and constructed of piezoelectric ceramic. What is piezoelectric ceramic, and how does it work? Indeed, as early as the author’s introduction to the lighter principle article, which is briefly stated here, the comprehension of the ultrasonic humidifier’s operating principle plays a significant role. Piezoelectric ceramics are also a piezoelectric element; piezoelectric elements have a piezoelectric effect, which may be classified into two types: positive and inverse.
The positive piezoelectric effect is manifested as follows: using an external force to squeeze the surface of the piezoelectric element, the surface of the piezoelectric element will produce a charge due to deformation, showing charged. In this process, mechanical energy is converted to electrical energy.
The inverse piezoelectric effect is manifested as follows: when electricity is applied to both ends of the piezoelectric element, the piezoelectric element will produce a deformation. If passed into the high-frequency electricity, the piezoelectric element will repeatedly deformation, that is, vibration. In this process, the electrical energy is converted into mechanical energy.
The inverse piezoelectric effect, or the conversion of electrical energy to mechanical energy, is used in the ultrasonic humidifier atomizer. The entrance of high-frequency voltage causes the atomization piece (piezoelectric element) to oscillate, according to the introduction of the inverse piezoelectric effect. The ultrasonic humidifier oscillation circuit generates 0.65MHZ high-frequency voltage, and because the atomizer has an inherent frequency of 1.7MHZ crystal, the coupling capacitor supplied to the atomizer generates 0.65MHZ high-frequency voltage.
