Microwave resonant cavity for electronic cigarette

Abstract

The invention discloses a microwave resonant cavity (221) for an electronic cigarette. The microwave resonant cavity is of a cylinder shape, wherein a second oil guiding component (223) is arranged inthe microwave resonant cavity (221) along the axial direction; and a coupling hole (225) is formed in the side wall of the microwave resonant cavity (221). When being applied to the electronic cigarette, the microwave resonant cavity has the advantages that instant heating is realized, the efficiency is high, heat uniformity is good, non-contact atomization is realized, the low temperature sterilization of tobacco tar can be realized, and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a microwave resonant cavity used in electronic cigarettes. Background technique [0002] In recent years, under the dual pressure of global tobacco control and public health public opinion, the development of traditional cigarettes has been more and more restricted. The upsurge of healthy consumption. [0003] At present, the mainstream e-cigarettes on the market at home and abroad generally adopt electrothermal atomization. This method is based on the principle of heat conduction. The electronic cigarette is triggered by an airflow sensor or a mechanical button, and the circuit is turned on to supply power to heating components such as metal heating wires or ceramic heating sheets. The heated e-liquid is atomized to produce aerosols for users to enjoy. Although the working principle of the electrothermal atomization method is simple and the technology...

AI Technical Summary

Problems solved by technology

Although the working principle of the electrothermal atomization method is simple and the technology application is relatively mature, there are generally the following problems: 1. The core patent of the atomization technology is controlled by Imperial Tobacco Company, which has a greater risk of intellectual property infringement; 2. Continuous smoking of electronic cigarettes During the process, the heating components continue to heat up to over 500°C, and there are potential safety risks. At the same time, the high-temperature pyrolysis of e-liquid will release harmful components such as aldehydes, which poses health risks to smokers; 3. It belongs to contact atomization, e-liquid It is easy to sinter and adhere to the surface of the heating component and produce carbon deposits, and then pyrolysis releases harmful components such as CO, emits a burnt smell, or affects the working performance and service life of the heating component; Transfer to aerosols also poses health risks
