Although e-cigarettes have styles or brands, e-cigarettes generally consist of three parts: a tobacco pipe containing a nicotine solution, an evaporation device, and a battery. The atomizer is powered by a battery rod and can convert the liquid nicotine inside the cartridge into a mist so that when the user smokes, there is a smoking-like feeling to achieve "spray." It can even add flavors such as chocolate and mint to the tobacco pipe according to personal preference. Manufacturers claim that electronic cigarettes have no harmful components such as tar, suspended particles, etc., and are therefore healthier than traditional cigarettes.
There are also two parts: the battery rod, atomizer smoke bomb, the so-called second-generation electronic cigarette.
