Description

Technical Field

[0002] The principle of an electronic atomization device is to heat a liquid to its boiling point to form atomized steam through heating. The atomized steam is mixed with air to form an aerosol substance, which is currently widely used in the field of electronic cigarettes and can also be used in fields such as home, beauty, and medical treatment.

[0003] The core of an atomization device lies in the atomization core, which is mainly composed of a heating element and a liquid guiding body. Among them, the liquid guiding cotton atomization core is the most popular in the market. The liquid guiding cotton is made of natural cotton fibers, which is easy to obtain, has a high reduction degree of the atomized liquid taste, and is environmentally friendly. However, there are also some problems. For example, it is relatively soft, the liquid guiding gap size is uneven, and poor stability is the pain point of the liquid guiding cotton atomization core. Moreover, the atomization device needs to be portable and applicable frequently, so the atomization device is generally small. The power supply part of the atomization device is small, resulting in poor strength of the heating element, and it is more difficult to stably combine the heating element and the liquid guiding cotton.
