Description

Heating element structure, atomizing core and atomizer Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to a heating element structure, an atomizing core, and an atomizer. Background Technology

[0002] Electronic atomizing devices work by heating a liquid to its boiling point to form atomized vapor. The atomized vapor mixes with air to form an aerosol, which is currently widely used in the field of electronic cigarettes, and can also be used in home, beauty, and medical fields.

[0003] The core of an atomizing device lies in the atomizing coil, which mainly consists of a heating element and a liquid guide. Among them, the liquid-guided cotton atomizing coil is the most popular in the market. Liquid-guided cotton is made of natural cotton fibers, which are easy to obtain and have advantages such as high flavor reproduction of the atomized liquid and environmental friendliness. However, it also has some problems, such as being relatively soft, having uneven liquid guide gaps, and poor stability. These are the pain points of liquid-guided cotton atomizing coils. Moreover, atomizing devices need to be portable and used frequently, so atomizing devices are generally small. The small power supply section of the atomizing device results in poor heating element strength, and the combination of heating element and liquid-guided cotton is more difficult to stabilize.
