[0002] An electronic cigarette, also known as an e-cigarette, is mainly used for quitting smoking and replacing cigarettes. It has a taste similar to that of a cigarette, but an e-cigarette does not contain other harmful components such as tar and suspended particles in a cigarette.

[0003] Currently, the atomizer of a disposable electronic cigarette on the market is generally arranged in an oil storage tank. Due to volume limitations, the oil storage capacity of the oil storage tank is limited. When the e-liquid in the oil storage tank is exhausted, the atomizer is far from reaching its designed service life, resulting in waste of resources. Moreover, most of the existing atomizers have a single heating wire structure. As the use time increases, more and more e-carbon accumulates on the heating wire, which easily causes the wick to burn and shortens the service life of the atomizer. If the power of the heating wire is reduced, the taste of the smoke is very poor. Therefore, the existing technology has defects and needs to be improved. Summary of the Utility Model
