A cartomizer section of an electronic cigarette can be connected to a battery section of the electronic cigarette. The cartomizer section comprises a liquid reservoir operable to store liquid material and a one-way valve. The one-way valve is operable to seal an end of the cartomizer section which is in fluid communication with the liquid reservoir. The one-way valve is configured to allow one directional air flow towards a user's mouth during a draw on the electronic cigarette so as to prevent back flow of vapor produced during operation of the electronic cigarette towards the battery section. |
