technical field

The present application relates to the technical field of electronic cigarettes, and more specifically, to an atomizing device for electronic cigarettes and electronic cigarettes.

Background technique

In recent years, e-cigarettes have been favored by consumers for their ease of use and low harm to the body. In order to meet the needs of portability and ease of use, electronic cigarettes have a design trend of miniaturization and light structure. However, it is difficult to make the existing electronic cigarettes thinner because there are many components inside the electronic cigarettes. Designing the internal space of the e-cigarette to be too small to meet the requirements of miniaturization design will lead to too compact internal components, resulting in greater resistance to smoking and poor user experience. On the other hand, because the existing electronic cigarettes are relatively thick, users feel bad in terms of grasping and carrying, and users also tend to feel uncomfortable when holding the air outlet of the electronic cigarette.

In this regard, it is necessary to improve the internal structure of electronic cigarettes and optimize electronic cigarette products.

Since the liquid in the liquid storage chamber 200 will gradually penetrate into the atomizing core assembly and be vaporized, the pressure in the liquid storage chamber 200 will gradually decrease with the use of the electronic cigarette. When the air pressure in the atomization chamber 200 is higher than the air pressure in the liquid storage chamber 100, the outside air enters the liquid storage chamber 100 through the ventilation channel 7 to realize the air pressure balance between the atomization chamber 200 and the liquid storage chamber 100, thereby making the liquid storage chamber 100 The liquid matrix can flow to the atomizing core assembly 3 .

With the generation of smoke, the smoke oil is gradually absorbed by the atomizing core assembly 3 to the side of the atomizing surface, and the liquid matrix on the side of the oil storage cavity decreases, which causes the air pressure to drop, forming a negative pressure. The air pressure on the side of the atomization chamber 200 is relatively high, and the outside air will push the one-way ventilation seal through the ventilation channel 7 and flow into the liquid storage chamber 100 to achieve air pressure balance.
