Variable-frequency surface acoustic wave electronic cigarette

A variable-frequency surface acoustic wave electronic cigarette, comprising an atomizer;

• wherein 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;
• and a porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip;
• wherein the inverted trapezoidal interdigital transducer comprises a plurality of metal interdigital electrodes and reflective electrodes, which are in an inverted trapezoidal shape;
• the inverted trapezoidal interdigital transducer further comprises two metal electrode bus bars, namely a first metal electrode bus bar and a second metal electrode bus bar;
• a plurality of first metal interdigital electrodes are connected to the first metal electrode bus bar through a relatively long trapezoidal bottom, and a plurality of second metal interdigital electrodes are connected to the second metal electrode bus bar through a relatively short trapezoidal bottom;
• the plurality of first metal interdigital electrodes and the plurality of second metal interdigital electrodes are arranged in a finger-crossed shape, and a reflective electrode is embedded between a first metal interdigital electrode and a second metal interdigital electrode.
