A liquid atomizing device and related method

Abstract

This invention provides a liquid atomizing device and related method. The device includes: a liquid atomizing device body; the liquid atomizing device body includes a base, a heat sink, a piezoelectric chip, an interdigital transducer, and a porous material liquid-absorbing layer; the base has a hollow interior forming a liquid storage tank to store the liquid to be atomized; the heat sink is fixedly connected to the base and extends at least partially into the liquid storage tank; the interdigital transducer is disposed on the upper surface of the piezoelectric chip, and the lower surface of the piezoelectric chip is in contact with the heat sink; the porous material liquid-absorbing layer is vertically disposed on the side of the piezoelectric chip, and one end of the porous material liquid-absorbing layer is inserted into the liquid storage tank to draw liquid from the storage tank to the edge of the piezoelectric chip; under the drive of a radio frequency signal, the interdigital transducer generates surface acoustic waves and bulk acoustic waves on the piezoelectric chip, thereby atomizing the liquid drawn out by the porous material liquid-absorbing layer. This device reduces the volume of the piezoelectric chip, improves the heat dissipation effect, avoids high-temperature damage to the piezoelectric chip, and achieves a significant increase in the liquid atomization rate.
