Description

Title of Invention: Electronic Atomization Unit with Parallel Dual Atomization Units

The present invention relates to the field of electronic cigarette technology, and more particularly to an electronic aerosolizer having a parallel dual atomizing unit.

Background technique

[0002] Conventional tobacco-type cigarettes, because they contain smoke tar, are easily inhaled into the human body during smoking, causing great health hazards. E-cigarettes usually use the electronic cigarette smoke liquid to heat the atomizing device to emit smoke for the smoker. Since the electronic cigarette liquid does not contain the tobacco tar in the tobacco, the electronic cigarette gradually replaces the cigarette and is widely used.

[0003] In order to increase the amount of smoke smoked by a single cigarette in an existing electronic cigarette, an electronic cigarette atomizer having a double heating wire is generally used, and the existing dual heating wire electronic cigarette has two limitations due to space. The heating wire generally adopts a structure arranged on the same axis in the atomization chamber. This structure needs to flow through the two heating wires before and after the air entering the atomization chamber, and cannot contact the two heating wires at the same time, thereby reducing the atomization. Effect; The heating wire in the existing electronic aerosolization unit is generally supported by the atomization seat, and the atomization seat has the requirements of insulation and sealing. When the user frequently smokes, due to the high temperature generated by the double atomization unit, the atomization seat is easily burned, and the atomization seat is deformed, so that the atomization unit is easily lost, resulting in insufficient contact with the air flow, thereby affecting the smoke liquid. The atomization effect; the burning smell produced by the high temperature burning causes the e-cigarette user to have a reduced smoking taste, resulting in a bad smoking experience.
