Abstract
Description

[0002] With the rapid development of electronic cigarette technology, consumers have higher and higher requirements for the use experience of electronic cigarettes, which has also promoted the continuous optimization and improvement of electronic cigarettes to meet the diverse needs of different consumers. Existing electronic cigarettes mainly include two types: disposable electronic cigarettes and cartridge-changing electronic cigarettes. Disposable electronic cigarettes refer to closed electronic cigarettes with a cigarette rod and a cigarette oil integrated, which can be charged but cannot add or replace the cigarette oil. The cigarette oil is discarded after it is used up. The cartridge-changing electronic cigarette is composed of a cigarette cartridge unit consisting of a nozzle shell, an oil cup, an atomizer core, and a power terminal, and a battery host unit consisting of a host shell, a battery, a control panel, an airflow sensor, etc. For disposable electronic cigarettes, it is limited to a single flavor, usually to control costs, and it does not have structures such as adjusting the size of the airflow and gas-electric isolation. For this reason, it is usually explored, studied, and improved for cartridge-changing electronic cigarettes. To this end, technicians in this field have conducted research and improvements based on the existing cartridge-changing electronic cigarettes. Now there is an atomizer core with double heating wires arranged up and down, so that when a large amount of smoke is required, the double heating wires can be turned on, and when there is no need for a large delay, one of the heating wires can be turned on. However, the existing cartridge-type electronic cigarettes with dual heating wire mesh atomizer cores lack airflow regulation. The power is increased but the air intake is not matched, which will affect the taste. In addition, the control board, airflow sensor, battery and airway in the battery host are connected, and the oil-liquid mixture that is easily condensed enters the pollution control board, airflow sensor and battery, causing the electronic cigarette to malfunction easily.
