Technical Field

[0001] The utility model relates to the technical field of electronic cigarette products, and in particular to a press-to-fill electronic cigarette. Background Art

[0002] Although smoking is harmful to health and poses health risks to the respiratory system, quitting smoking is very difficult. In response to consumer demand, an e-cigarette with the same appearance and similar taste as cigarettes has appeared on the market. It is mainly used to simulate the feeling of smoking without affecting health, so as to help smokers quit smoking or replace cigarettes. E-cigarettes atomize the tobacco oil to satisfy smokers' addiction. After the tobacco oil is injected into the atomization chamber, the smoke is generated and floats out through the flue. Traditional e-cigarettes have complex structures and cumbersome operations when injecting tobacco oil into the atomization chamber, and need to be improved. Summary of the Invention

The oil assembly 3 includes a movable rod 31, and an oil storage hole 311 is provided below the movable rod 31. When there is no need to inject smoke oil into the atomization bin 22, the oil storage holes 311 are all located in the oil storage bin 21, and the smoke oil in the oil storage bin 21 enters the oil storage hole 311. When it is necessary to inject smoke oil into the atomization bin 22, the driving part 13 drives the movable rod 31 to move downward so that the oil storage hole 311 enters the atomization bin 22, and the smoke oil in the oil storage hole 311 flows into the atomization bin 22. When the smoke oil injected into the atomization bin 22 reaches a certain amount, the driving part 13 drives the movable rod 31 to move upward until the oil storage hole 311 is completely separated from the atomization bin 22. The electronic cigarette is turned on, and the smoke oil in the atomization bin 22 forms atomized gas, which enters the lower flue 23 through the first side hole 231 and finally floats out from the upper flue 12, meeting the consumer's usage needs.
