Development history of electronic smog core

2020/10/22|Knowledge

In 2017, the appearance of Juul cigarette and the research and development of nicotine salt made this product, born in China and detonated abroad, return to China again. With the high product characteristics of tobacco, we won the highest flow of venture capital industry in 2019. Electronic cigarette sets have also completed the iterative update from simulation smoke to large smoke box, and then to more convenient small smoke.

At present, our common cigarette oil type electronic cigarette is generally composed of a cigarette rod, an atomization core and an atomization bin. The battery is set in the cigarette rod, and the atomization core is set in the cigarette oil room. Among them, the atomization core is the heart of the whole electronic cigarette. The cigarette oil is atomized into smoke through the atomization core, and the atomized gas is exported to the cigarette holder, and finally the purpose of relieving addiction or replacing cigarette is achieved.

In order to match the characteristics of different cigarette sets and cigarette oils, improve the problems in the use process and make the atomization effect better, the atomization core has also experienced several generations of evolution

First generation: glass fiber rope wrapped with heating wire

In the early stage of e-cigarette development, the earliest atomization oil guide material is glass fiber rope. It has the characteristics of high temperature resistance, strong oil absorption and fast oil conduction speed. However, it is easy to produce floccule when it is not absorbed and exposed at rest. Between 2014 and 2015, many e-cigarette users were worried about the phenomenon of "powder falling" of glass fiber rope into the lung, so this material has been gradually eliminated by mainstream equipment in China.

The second generation: resistance silk cotton core

It is still widely used as atomizing core material. In the early stage, the structure of atomization core of large smoke box was resistance silk cotton core structure. Cotton fiber is used as oil guide material, and heating wire is wrapped outside. The advantages of oil guide cotton are large oil storage, good oil conductivity, and full and real smoke taste. Up to now, the cotton oil guide material has also experienced the development process from degreasing cotton, organic cotton to now long staple cotton and other professional electronic cigarette cotton.

However, the life of cotton core is short, easy to dry burn, and the taste stability is not enough. Therefore, with the increase of e-cigarettes in the market, in order to obtain a more stable atomization taste, manufacturers began to study the substitute materials of atomization core, and microporous ceramic materials began to be applied.

The third generation: Ceramic atomizing core

Small smoke mainstream atomization core material. Compared with cotton core, ceramic core atomization taste is more delicate, smoke inlet is more smooth. The stability and durability of ceramic core also solves the problems of cotton core such as easy dry burning, unstable taste and easy paste core. It can make the atomization taste stable from the beginning to the end (which is not absolute, of course)

First, ceramic core is atomized and pressed around the ceramic core.

In the second generation of microporous ceramic atomizing core, the heating wire is embedded on the surface of microporous ceramic substrate by printing.

The third generation of microporous ceramic atomizing core is to embed the heating wire into the surface of microporous ceramic matrix.

The third generation ceramic atomizing core is widely used in small smoke in the market. With the development of new materials, the structure of atomizer will be more strict in the future. The old and stubborn problem of electronic cigarette industry, oil leakage, may also be solved together.
