Variable-frequency surface acoustic wave electronic cigarette

Abstract

The invention discloses a variable-frequency surface acoustic wave electronic cigarette which comprises an atomizer (2), wherein an atomization cavity (213) is formed in the atomizer (2), a variable-frequency surface acoustic wave atomization chip (203) is arranged on the lower portion of the atomization cavity (213), and an inverted-trapezoidal interdigital transducer (2037) is arranged on the variable-frequency surface acoustic wave atomization chip (203). A tar storage cavity (205) is formed in the atomization cavity (213), and porous ceramic pieces (204) are arranged between the tar storage cavity (205) and the atomization chip (203). According to the variable-frequency surface acoustic wave electronic cigarette, the working frequency can be freely adjusted within the set range, and then automatic regulation and control over the smoke particle size of tobacco tar atomization are achieved.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, in particular to a frequency-variable surface acoustic wave electronic cigarette. Background technique [0002] At present, electric heating atomizing electronic cigarettes occupy the mainstream market of electronic cigarettes, which use resistance wire heating to generate local high temperature, so that the smoke oil in the cotton core or porous ceramic sheet is atomized to form aerosol for users to smoke. The electric heating atomizing electronic cigarette has fast heat conduction rate and high atomization efficiency, but it is easy to produce harmful substances such as formaldehyde and carbon monoxide under the action of high temperature, which not only poses health and safety risks, but also greatly reduces the taste of smoking. Another kind of electronic cigarette is ultrasonic atomization electronic cigarette. This electronic cigarette needs to spread a thin layer of smoke oil...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the applicant designed an electronic cigarette system that uses surface acoustic waves to atomize e-liquid (see Chinese patent ZL201810076941.1). Health risks, high consumption, low efficiency, and poor taste of ultrasonic atomization, but the particle size of the smoke after the system is atomized is basically determined and cannot be adjusted arbitrarily, which affects the smoking experience
