Problems solved by technology

The disadvantages of this type of atomizer heating element are: 1. The fine filaments in the glass fiber rope have the risk of being inhaled into the lungs of consumers; 3. The heating area of ​​the heating wire is small and the working temperature is high, which is easy to cause carbonization of the e-liquid and produce peculiar smell, which affects the taste and working life of the e-cigarette vapor
As a result, the porous ceramics of this type of atomizer heating element are not strong enough due to the low sintering temperature, and the ceramic body has a loose structure.
When the porous ceramic heater is soaked in the e-liquid for a long time, the porous ceramic porcelain body is prone to powder loss, and the free porcelain powder will be inhaled by consumers.
At the same time, the heating wire buried and fired inside the porous ceramic will easily cause the micropores of the porous ceramic to be blocked by carbon deposits during the working process, which will cause the e-liquid to burn, affecting the taste and the reduction degree of the e-liquid
[0008] To sum up, the existing first-generation oil-conducting cotton or glass fiber rope plus winding nickel-chromium alloy heating wire, the second-generation porous ceramic plus winding nickel-chromium alloy heating wire, and the third-generation porous ceramic plus buried nickel-chromium alloy heating wire Chromium alloy heating wires have various defects and problems, which cannot meet the performance requirements of the development of electronic cigarette products for atomizer heaters
