[0002] Electronic cigarettes in the prior art are usually designed with only one oil storage chamber for supplying the heating core with oil to generate smoke. Some electronic cigarettes have the oil storage chamber filled with oil during production, but this method leads to problems such as oil leakage and deterioration during storage and transportation. Some electronic cigarettes are not filled with oil during production, and users fill the oil storage chamber with oil when purchasing and using them. This is more complicated for users to operate and is also prone to oil leakage during the filling process, which pollutes the electronic cigarette and affects the user experience.

[0003] In order to improve the above situation, some e-cigarettes are equipped with oil storage bottles, which are sealed with bottle caps during transportation and storage. Users need to unscrew the bottle caps after purchase, and then install the oil storage bottles on the e-cigarettes to allow the oil to enter the oil storage chamber to supply the heating core. When the user operates, the oil is still easy to spill out of the oil bottle and pollute the e-cigarette. The operation is also not simple, which affects the user experience. Utility Model Content
