Description

Electronic atomization device and its atomizer and atomization core

Technical field

The present invention relates to the field of atomization technology, and in particular to an electronic atomization device, its atomizer and atomization core.

Background technique

Cotton cores and ceramic cores are the mainstream atomizer cores currently on the market. Compared with cotton cores, although ceramic cores have significant advantages in preventing leakage and anti-coking, they also have significant disadvantages. For example, relatively speaking, the atomization volume of ceramic cores is smaller than that of cotton cores. If you want to achieve a higher atomization volume, you need to use high power output. The atomizing cores of current electronic atomization devices are mostly ceramic atomizing cores, which are composed of porous ceramics and thick film heating circuits. The atomized liquid is gradually transferred from the liquid storage chamber to the heating circuit under the action of the capillary force of the micro-through holes in the porous ceramics. Atomization is completed at the membrane. The liquid conduction ability of ceramic atomizing cores is often worse than that of cotton cores, so it is difficult for ceramic atomizing cores to use high power density output. Once high power density output is used, the heating film of the ceramic atomizing core will dry out, resulting in fog. Core failure.

The existing ceramic atomizing cores all use single-side atomization or single-sided atomization. The atomizing core should be installed with the atomizing surface facing up, the atomizing surface facing down, or using side atomization. Due to structural design reasons, it is difficult for the existing ceramic atomizing core to achieve the effect of high power output and high smoke volume.

In addition, for atomized liquids with high sugar content, the heating element is easy to coke after multiple puffs, and the coking of the heating element seriously affects the taste. This is the main reason for the poor taste consistency of this type of atomizer core during the puffing process.
