Harmful substances such as substances, which can seriously damage human health. In order to avoid the cigarettes producing a large amount of harmful substances and enjoying the unique taste of the cigarettes, the cigarettes can be heated without burning. The electronic smoking articles are used for smoking by the smoking user when the cigarette products are placed therein for electric heating. Bake at a flammable temperature until smoke is emitted, allowing smokers to inhale cigarette smoke. Since tobacco products are burned by heating instead of open flames, the user is prevented from inhaling a large amount of harmful substances produced by burning of tobacco products due to open flames, so smoking using electronic smoking articles is gradually being used by the public.
