Description

An electronic cigarette atomizer, an atomizer and a method for generating smoke in an electronic cigarette

Technical field

The invention belongs to the technical field of electronic cigarettes, and in particular relates to an electronic cigarette atomizer, an atomizer and a method for generating smoke in an electronic cigarette.

Background technique

Currently, a heating element is used to heat the e-liquid on the atomizing cotton to produce smoke for the user to smoke. In the electronic cigarette core, the heating element is in direct contact with the atomizing cotton. The heat generated after the heating element is energized is directly transferred to the atomizing cotton, heating the e-liquid on the atomizing cotton to produce smoke.

The existing method of heating e-liquid to generate smoke through direct heat transfer has the following shortcomings:

First, since the heating element is in direct contact with the atomized cotton, the atomized cotton is easily scorched by the heating element, which affects the taste of the smoke and the service life of the e-cigarette.

Second, when the e-cigarette is left standing, the heating element is in direct contact with the atomizing cotton, so the heating element is soaked in e-liquid for a long time. A layer of e-liquid residue will condense on the surface of the heating element. When the heating element works again, it will condense on it. The cigarette oil residue on the surface is burned or carbonized to produce odor, which seriously affects the taste of smoke and endangers human health.

Third, in order to prevent the atomized cotton from being partially burned by the heating element, the atomized cotton is generally designed to be thicker so that it can absorb more e-liquid and heat. At the same time, it is very likely that the atomized cotton will be oversaturated and leakage, which requires a larger output power to atomize into smoke. Therefore, the greater the output power, the shorter the battery life and the lower the safety performance.

Contents of the invention

In the existing electronic cigarette atomizing core, the heating element is in direct contact with the atomizing cotton. The heat generated by the heating element is directly transferred to the e-liquid on the atomizing cotton, and the e-liquid is heated to produce smoke. This heating method is easy to burn and produces smoke. The smoke tastes bad and endangers human health. At the same time, the output power of atomization is large, the battery life is short, the e-cigarette life is short, and the safety performance is low. The purpose of the present invention is to provide an improved electronic cigarette atomizer, an atomizer and a method for generating smoke in an electronic cigarette in view of the above-mentioned shortcomings of the prior art. The structure is simple, easy to disassemble and assemble, and the atomized cotton is not easily burned. , there will be no cigarette oil residue condensed on the surface of the heating element, the heating element requires less atomization power, the smoke tastes good, it will not endanger human health, the battery has a long service life, high safety performance, and the e-cigarette has a long service life.
