Acoustic surface wave liquid guide device

Abstract

The invention discloses an acoustic surface wave liquid guide device which comprises a pieozelectric substrate (1), a first interdigital transducer (51), a liquid storage bin (6) and a micro runner (8). The liquid storage bin (6) and the micro runner (8) are closely fitted on the surface of the pieozelectric substrate (1), and the first interdigital transducer (51) and the micro runner (8) are arranged on two sides of the liquid storage bin (6) which is communicated with the micro runner (8). The acoustic surface wave liquid guide device can ensure continuous and stable pumping and timely andsufficient atomizing of tobacco liquid, the technical defect of passive liquid guide is overcome, and empty drying is avoided, so that smoking quality is improved, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a surface acoustic wave liquid guiding device. Background technique [0002] In recent years, under the dual pressure of the global tobacco control situation and public health public opinion, the development of traditional cigarettes has been more and more restricted. As a new type of low-harm cigarette substitute, electronic cigarettes are increasingly popular among consumers. The global e-cigarette market is showing a continuous development trend. [0003] Most of the existing electronic cigarettes are mainly electrothermal atomization, and a small part of them use ultrasonic atomization. Electrothermal atomization is based on the principle of heat conduction. The electronic cigarette is triggered by the airflow sensor, mechanical button or touch button, and the circuit is turned on to supply power to the heating wire made of nickel-chromium alloy, st...

Problems solved by technology

[0004] In view of the shortcomings of the above-mentioned prior art, the present invention organically combines the unique advantages of surface acoustic wave technology with the functional characteristics and performance requirements of electronic cigarettes, and based on the acoustic flow effect of surface acoustic wave and the atomization mechanism of standing wave surface acoustic wave, provides An electronic cigarette system that uses surface acoustic waves to realize active liquid guidance, surface acoustic wave non-contact atomization, and surface acoustic waves, which effectively overcomes the potential safety and health risks caused by the rapid and high heat of electrothermal atomization, and the high consumption and low efficiency of ultrasonic atomization , The particle size distribution of the aerosol is not uniform, and it is not suitable for the atomization of high-viscosity e-liquid, and reasonably solves the problem that the passive liquid guide of the electronic cigarette in the prior art makes the suction quality poor, and the contact atomization affects the heating wire or vibration Problems with the atomization performance or service life of the sheet
