Problems solved by technology

At present, electronic cigarettes on the market use glass fiber cotton as the drainage carrier, and due to the needs of the production process, chemical binders containing harmful substances are usually added in the production process of glass fiber cotton, which leads to consumption when used in electronic cigarettes. The user releases harmful substances during use, and there will be a smell of scorched chemical substances when heated, which seriously affects the taste and damages the health of users
At the same time, the atomizing core of the electronic cigarette is a device that needs to be heated repeatedly during the working process. Due to the large thermal expansion coefficient of ordinary ceramic products, it is easy to burst during repeated heating, so the service life is short and there are certain safety hazards.
