Abstract
A variable-frequency surface acoustic wave electronic cigarette includes an atomizer. An atomization cavity is disposed in the atomizer, and a variable-frequency surface acoustic wave atomization chip is disposed at a lower portion of the atomization cavity. An inverted trapezoidal interdigital transducer is disposed on the variable-frequency surface acoustic wave atomization chip. An e-liquid storage cavity is disposed in the atomization cavity. A porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip. The new variable-frequency surface acoustic wave electronic cigarette can realize any adjustment of the working frequency within a set range, thereby realizing the autonomous regulation and control of a smoke particle size after atomization of the e-liquid.
