The development of electronic cigarette Atomizing core

The evolution of the flexibility of vapes has gradually evolved from a large smoke box to a small rod-type vape. The common E-liquid type vape is generally composed of a tobacco rod, an Atomizing core and an E-liquid chamber. The battery is set in the smoke. Inside the rod, the Atomizing core is placed in the E-liquid chamber. After the battery is energized, the heating wire is heated. The heating wire atomizes the E-liquid in the Atomizing core, and the atomized gas is led to the cigarette holder, wherein the Atomizing core is for the E-liquid mist. It plays an important role.

However, due to the structural design problem of the existing Atomizing core, the amount of E-liquid entering the Atomizing core is unstable, resulting in poor atomization effect and small amount of smoke. In order to improve the use of the process, the Atomizing core structure has undergone multiple generations of evolution:

1. The earliest large smoke box Atomizing core structure adopts a resistance silk core structure. Cotton fiber is used as the oil guiding material, and the heating wire is wound outside.

2. In order to solve the problem of dry burning of cotton, glass fiber rope was used as the oil guiding material, and the heating wire was outsourced.

The advantage of the oil guiding cotton is that it has a large oil storage capacity, good oil guiding property and low cost, but has a short life span and is easy to dry and is suitable for disposable electronic cigarettes. With the increase of the electronic cigarettes on the market, in order to obtain a better atomization and anti-drying, manufacturers began to research on Atomizing core alternative materials, and microporous ceramic materials began to be applied to determine the oil supply capacity of Atomizing core.

3, the first generation of microporous ceramic Atomizing core, using injection molding, the ceramic material is fired around the heating wire.

4. The second generation of microporous ceramic Atomizing core uses a printing method to embed the heating wire into the surface of the microporous ceramic substrate.

5. The third generation of microporous ceramic Atomizing core is to embed the heating wire into the surface of the microporous ceramic substrate.

In the future, there may be an Atomizing core with electromagnetic heating and ultrasonic heating. At present, microporous ceramics are still the mainstream in the field of electronic cigarettes. After the microporous ceramics absorb E-liquid, the E-liquid is transferred to the vicinity of the heating circuit. After the E-liquid is heated, steam is formed, and the steam meets to form condensation. The droplets, combined with air, form an aerosol.
