Abstract
An electronic cigarette assembly includes an electronic cigarette body and an expanded tobacco liquid bottle. The electronic cigarette body includes a storage chamber. The storage chamber is provided with first liquid absorbing cotton and a first liquid passing hole. The expanded tobacco liquid bottle stores tobacco liquid and is provided with second liquid passing holes and a movable part. When the expanded tobacco liquid bottle is not assembled with the electronic cigarette body, the movable part covers the second liquid passing holes to prevent the tobacco liquid from flowing out of the second liquid passing holes. When the expanded tobacco liquid bottle is assembled with the electronic cigarette body, the movable part moves to open the second liquid passing holes, allowing the tobacco liquid to pass through the second liquid passing holes and the first liquid passing hole to be adsorbed by the first liquid absorbing cotton.
