Cartridge assembly of electronic cigarette and electronic cigarette with same

Abstract

The invention relates to the technical field of electronic cigarettes. The problem of liquid leakage of a cartridge assembly of an electronic cigarette in a low-pressure environment is solved. The invention provides a cartridge assembly of an electronic cigarette and the electronic cigarette with the cartridge assembly. The cartridge assembly includes: an e-liquid bin, an atomizer, a micro pump and a one-way valve; a liquid outlet and a gas inlet are formed in the side wall of the e-liquid bin; at least one part of the side wall of the e-liquid bin except the part adjacent to the liquid outletand the gas inlet forms a flexible diaphragm, the micro pump communicates with the e-liquid cavity and the atomizer and used for pumping e-liquid in the tobacco e-liquid cavity into the atomizer, andthe one-way valve is arranged at the gas inlet and used for controlling gas to only enter the e-liquid cavity in a one-way mode. The flexible diaphragm correspondingly deforms according to the relationship between the internal pressure of the e-liquid cavity and the external pressure of the e-liquid cavity, so that the balance of the internal and external air pressure of the e-liquid bin is realized, the situation that the e-liquid is pushed out due to higher internal pressure of the e-liquid cavity is prevented, and the phenomenon of liquid leakage of the electronic cigarette is prevented.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a cartridge component of an electronic cigarette and an electronic cigarette having the same. Background technique [0002] Active fuel supply electronic cigarettes in the prior art mostly use micropumps to control and adjust the fuel supply. By matching the fuel consumption of the atomizer and introducing a feedback mechanism in the control link, the smoke is realized. The dynamic balance of oil supply and consumption makes the smoke oil fully atomized. In a low-pressure environment, the oil leakage of electronic cigarette pods is serious. This is due to the pressure difference between the internal air pressure of the oil tank and the external low-pressure environment, and the e-liquid is pushed out of the oil tank, causing oil leakage. Smoke pods will also leak oil in a low-pressure environment. [0003] Secondly, the micropump as the core component has a weak a...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the micropump of the electronic cigarette has weak ability to independently remove impurities and air bubbles, once impurities or air bubbles enter the micropump, the performance of the micropump will be reduced or even the micropump will be blocked.
