When using, a battery of the battery component2′ supplies an electrical power to a heating coil inside the atomization assembly3′, so that the heating coil can generate heat to heat and atomize cigarette oil in the oil storage assembly4′, thus the smoke which is inhaled by users can be produced.

In the prior art, the oil storage assembly mainly includes two types, one of them is an oil storage cotton while the other is an oil storage bottle. The oil storage cotton is made of a loose and porous materials such as foam, and the oil storage cotton stores the cigarette oil by a means of adsorption. As the oil storage cotton is soft, it is convenient to be installed and sealed inside the atomization assembly3′, and will not be damaged by a collision and a vibration from an external environment. However, an amount of the cigarette oil which is stored by the oil storage cotton is generally small, and it is difficult to maintain a need for using the electronic cigarette in a continuous long time. Further, as the oil storage cotton is needed to be sealed inside the atomization assembly3′ to prevent a volatilization of the cigarette oil, after exhausting the cigarette oil which is absorbed by the oil storage cotton, an outer casing of the atomization assembly3′ should be opened to add cigarette oil to the oil storage cotton or change the oil storage cotton, this operation is complicated, thus, the oil storage bottle is generally applied for the oil storage assembly, nevertheless, in the prior art, the oil storage bottle contains following defects:
