Ultrasonic atomization device

Abstract

The invention discloses an ultrasonic atomization device which comprises an atomized liquid storage chamber for storing atomized liquid, and an atomization chamber communicated with the atomized liquid storage chamber by a first through hole (54), wherein a piezoelectric ceramic atomization sheet (4) is arranged on an external wall of the atomization chamber; a power supply device (518) supplies power to the piezoelectric ceramic atomization sheet (4); the ultrasonic atomization device further comprises a pressure regulation chamber; and a pressure regulation component (5) is arranged between the pressure regulation chamber and the atomized liquid storage chamber. The ultrasonic atomization device adopting a special structure decreases ionic compounds physically deposited in atomization micropores in the liquid, prevents an atomization element from long-term contact with the liquid, and prevents salt plasma compounds from being naturally deposited in the atomization micropores, the service life of the atomization device is prolonged, and the leakage of the atomized liquid is avoided. The atomization device integrates atomization, humidification and external charging, and is convenient and simple, and convenient to carry, and the practical value of the atomization device is improved.

Description

technical field [0001] The invention relates to an atomizing device for atomizing liquid, in particular to an ultrasonic atomizing device using a piezoelectric ceramic atomizer. [0002] Background technique [0003] Nebulizers are often used for humidification in daily life and atomization of clinical medicines. In the prior art, nebulizers are usually bonded by a metal diaphragm with atomization micropores and a piezoelectric ceramic ring. After the atomizer is powered on, the radial stretching vibration of the piezoelectric ceramic ring drives the metal diaphragm to perform bending vibration, and the bending vibration of the metal diaphragm changes the shape of the cone-shaped atomization hole, forming a relative compression and relaxation process, driving the liquid The transmission, and the small-diameter end of the tapered hole is continuously produced with fine droplets to realize the liquid fluid drive, transportation and liquid atomization. [0004] The atomizatio...

Problems solved by technology

The atomization micropores of the atomization device at the present stage are easily blocked and the service life is short. At the same time, the internal and external pressure imbalance of the atomization device often occurs during the working process of the atomization device, which affects the atomization effect, and the atomization device at the present stage is only limited to liquid atomization , The function is single, which is not conducive to the marketization of the atomization device
