Description

Atomizer devices and atomizers

Technical field

The present invention relates to the field of atomization, and more specifically, to an atomization device and an atomizer.

Background technique

The electronic atomization device is a device that uses electric heating to heat the atomization liquid until it atomizes and evaporates to produce aerosol. It is currently widely used in the field of e-cigarettes. The electronic atomization device mainly consists of a power supply part, an atomization core, and an atomizer. It is composed of several liquid parts. The power supply part provides the electrical energy required for atomization. The atomizing core absorbs the atomizing liquid and heats the atomizing liquid to reach the boiling point and then evaporates to produce smoke.

A common problem with atomization devices is oil leakage and core smearing. How to control the supply and consumption of e-liquid to achieve a balance is the key to solving the problems of oil leakage and core smearing. Therefore, many structures have been developed to solve the problem of oil leakage in atomization devices. and methods, but each has its shortcomings. Some cannot completely avoid the problem of oil leakage, some will cause a waste of e-liquid, and some have complex structures and low production efficiency. Therefore, a simple and reliable structure is needed to effectively prevent leakage. At the same time, it has the advantages of simple structure and convenient assembly.

You can also use a solution with liquid storage cotton in the liquid storage tank. The liquid is stored in the liquid storage cotton. There are many micropore gaps in the liquid storage cotton, which can store the atomized liquid without dripping. The liquid storage cotton is in contact with the atomization core assembly. When the atomization core is atomized, the liquid is stored in the liquid storage cotton. When the atomization is consumed, the atomized liquid in the liquid storage cotton can be quickly replenished into the atomization core through capillary phenomenon, thereby realizing the supply demand of the liquid. The micropore gap of the liquid storage cotton itself can prevent the liquid from being absorbed by its own gravity. And leaked.

When the structure of liquid storage cotton is used in the liquid storage tank, the liquid is stored in the liquid storage cotton, so there is basically no problem of oil leakage. However, porous ceramics serve as a channel connecting the oil tank and the outside air. When the liquid is consumed When the air pressure in the oil tank is lower than the outside air pressure, the gas will enter the oil tank, and the porous ceramics serve as a channel connecting the oil tank and the outside air. The gas can only enter through the porous ceramics, so the gas will occupy part of the microstructure of the porous ceramics. The holes in the liquid conduction channel will cause the liquid supply to be unsmooth.
