A surface acoustic wave non-contact atomization device

Abstract

The invention discloses a surface acoustic wave non-contact atomization device. The surface acoustic wave non-contact atomization device comprises a piezoelectric substrate (1), T-shaped fiber paper (10), a second interdigital transducer (52) and a third interdigital transducer (53), wherein the second interdigital transducer (52) and the third interdigital transducer (53) are placed on the two sides of the T-shaped fiber paper (10), and the T-shaped fiber paper (10), the second interdigital transducer (52) and the third interdigital transducer (53) closely fit the surface of the piezoelectricsubstrate (1). The surface acoustic wave non-contact atomization device has a strong E-liquid atomization capability and can generate a large amount of smoke per unit time, and a user can quickly obtain a sense of satisfaction in smoking.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a surface acoustic wave non-contact atomizing device. Background technique [0002] In recent years, under the dual pressure of the global tobacco control situation and public opinion on public health, the development of traditional cigarettes has been increasingly restricted. As a new type of low-hazard cigarette substitute, electronic cigarettes are increasingly favored by consumers. The global e-cigarette market is showing a continuous development trend. [0003] Most of the existing electronic cigarettes are mainly electric atomization, and a small part adopts ultrasonic atomization. The electrothermal atomization is based on the principle of heat conduction. The electronic cigarette is triggered to work through the airflow sensor, mechanical button or touch button, and the conduction circuit supplies power to the heating wire wound by nickel-chromi...
