An exemplary atomizer includes a main body, an atomizing component received in the main body, and a liquid chamber configured for receiving tobacco liquid. The atomizing component is configured for generating aerosol from the tobacco liquid. The atomizing component and the liquid chamber cooperatively define a liquid passage therebetween. The atomizer further includes a liquid blocking element defining a notch. The liquid blocking element is capable of rotating relative to the main body between a first position where the liquid blocking element prevents the tobacco liquid in the liquid chamber from flowing into the liquid passage, and a second position where the notch is in alignment with the liquid passage, so that the tobacco liquid flows to the atomizing component via the liquid passage.

An exemplary atomizer includes a liquid supply component, an atomizing assembly, and a pricking means. The liquid supply component is configured for storing tobacco liquid. The liquid supply component has a sealing means for sealing the tobacco liquid therein. The pricking means for pricking the sealing structure so that the tobacco liquid flows to the atomizing assembly. The atomizing assembly is configured for heating the tobacco liquid to form aerosol.

The present invention provides an electronic cigarette and a battery device thereof. The battery device applied to an electronic cigarette, includes a cylindrical body, a first airflow channel, and two conductive members. The first air flowing channel extends axially through the cylindrical body. The conductive members are mounted to opposite ends of the cylindrical body, and keep insulation from an anode and a cathode of the battery device. The two conductive members further is electrically connected to each other. By virtue of the airflow channel defined in the cylindrical body of the battery device, it is easily to maintain the airflow channel being consistent, thereby enhancing the consistency of electronic cigarettes.
