Electronic cigarettes are electronic products that imitate cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that converts nicotine and other substances into vapor for users' consumption through atomization and other means. The World Health Organization has carried out a special study on electronic cigarettes and has come to a clear conclusion: electronic cigarettes are harmful to public health and are not a means to quit smoking. It is necessary to strengthen its control to avoid harm to adolescents and non-smokers.
The design of the first generation of electronic cigarettes completely imitates the shape of ordinary real cigarettes in appearance, yellow cigarette shells and white cigarette bodies. This generation of electronic cigarettes has been in fashion for several years because they look similar to real cigarettes and are accepted by customers at first glance. However, as more and more people use first-generation electronic cigarettes, especially foreign customers, they gradually discover many of the disadvantages of first-generation electronic cigarettes during their use, mainly in atomizers. The atomizer of the first generation of electronic cigarettes burns easily and the atomizer tip is easily damaged when replacing the chimney. Over time, it will wear out completely, eventually causing the atomizer to not emit smoke.
Second generation e-cigarettes are slightly longer than first generation e-cigarettes, with an overall diameter of 9.25 mm. The main feature is that the atomizer has been improved and there is a protective cover on the outside of the atomizer. The smoke bomb is inserted into the atomizer, while the first generation of electronic cigarettes is inserted into the smoke bomb by the atomizer, which is exactly the opposite of the two. The most prominent feature of the second generation of electronic cigarettes is the combination of cigarette pumps and atomizers.
The third generation electronic cigarettes use disposable atomizer cylinders, equivalent to disposable atomizers, which solve previous problems, greatly improve quality, and replace appearance and raw materials.
