Abstract
Embodiments of the invention disclose a combined ultrasonic atomizer, an atomization method thereof and electronic cigarette. The combined ultrasonic atomizer comprises a tobacco tar bin, an air inlet passage, a tobacco tar smoke outlet passage and an atomization component; the atomization component comprises a micropore atomization piece used for performing first-stage oscillation atomization on tobacco tar and a high-frequency atomization piece used for performing second-stage oscillation atomization on the tobacco tar; the micropore atomization piece is communicated with a tobacco tar outlet of the tobacco tar bin by direct contact or through a tobacco tar guide structure, and an ejection end of the micropore atomization piece is aligned to an atomization surface of the high-frequency atomization piece; and the air inlet passage communicates with an atomization cavity located between the micropore atomization piece and the high-frequency atomization piece, and the atomization cavity communicates with the tobacco tar smoke outlet passage.
