[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a cigarette cartridge and a cigarette rod combination and separation structure of a liquid electronic cigarette. Background Art
[0002] In the case of open-oil electronic cigarettes, the oil generally penetrates into the oil storage cotton, and then the atomizer core component in the center of the oil storage cotton atomizes it to form smoke for the smoker to inhale. Therefore, when the electronic cigarette is in use, a passage from the oil to the oil storage cotton must be formed. However, if the passage from the oil to the oil storage cotton still exists and is in an open state when the electronic cigarette is not in use, the oil storage cotton is prone to oil leakage.
[0003] Therefore, a solution is needed to conveniently open or close the passage from the smoke oil to the oil storage cotton. Summary of the invention
