The atomizing core is an important part of the e-cigarette. It is the heater that atomizes the fume oil and decides the taste together with the fume oil.
In the past, the mainstream is the cotton core; the advantage is low price, taste reduction degree is good; The disadvantage is prone to fry oil, oil leakage, and reliance on artificial, difficult industrial production and quality control.
Ceramic core nearly three years of research and development promotion, the advantages are not fried oil, low oil leakage rate, and large-scale industrial production. The disadvantage is that the price is relatively high, and the taste reduction degree is weak. Still, the product's reduction degree has been improved after iteration, so the ceramic core's permeability is improved.
It can be seen from the human body deposition model of aerosol particles that the reduction degree of the cotton core is high because the atomized particles are larger, ranging from 0.7 microns to 0.75 microns. Large particle size fog can feel the rich aroma in the nasal cavity and easier to deposit in the mouth and throat so that the oral satisfaction is stronger.
The ceramic core is the pursuit of fog particles fine, atomized particle size between 0.5 to 0.55 micron; such fog particle size is mainly felt by the nose smell cells, so you will feel the reduction degree is not enough.
In recent years, ceramic atomizing core to "no paste, durable" and other advantages, to gain market favor. Overseas experienced the natural replacement of the ceramic core to the cotton core. The domestic start is the ceramic core, the current domestic part of the brand. Out of cost considerations, there is a desire to improve the proportion of the cotton core.
But after research, the cotton core and ceramic core have advantages and disadvantages, will coexist for a long time. In reality, for small smoke, mainly use ceramic atomization core; Disposable electronic cigarette small cigarette, cotton core is the mainstream.
Closed smoke for new customers, although the ceramic core taste reduction degree is low, the experience is better, fewer quality problems, so the acceptance is higher; For repurchase customers, the ceramic core has formed a certain consumption habit.
At present, the atomizing core head is also studying the possibility of other materials. Still, it has not found a better material, which will be the basic reason for the long-term coexistence of ceramic core and cotton core.
