Before changing liquids of different flavors, it is best to clean the atomizer (be sure to clean it after a long time) to prevent the third bad smell (even burnt smell), but some people like to make their own flavors, ,custom vape pen  ，Specially smoked with flavor (for example, many people like to mix tobacco flavor and mint flavor).

The electronic cigarette consists of two parts, the upper part is called the atomizer, and the lower black or white stick is called the battery stick. When cleaning, unscrew the battery rod and set aside, do not let the battery rod touch water (the battery rod cannot be washed). Unscrew the cigarette holder on the atomizer and the metal base under the atomizer, and finally unscrew the atomizing core on the base, and the faucet can be rinsed freely (be careful not to lose the small rubber ring inside when screwing these things). Be sure to dry the base of the atomizer before finally attaching the battery stick, otherwise it will cause a short circuit and burn the battery stick!
