Abstract: An atomizer includes a main body. The main body includes an e-liquid chamber, a heating chamber, a heating element, and an e-liquid channel. The heating element is disposed in the heating chamber. The main body further includes at least one e-liquid inlet and at least one e-liquid outlet communicating with two ends of the e-liquid channel, respectively. The at least one e-liquid inlet is disposed in a bottom part of the e-liquid chamber. The at least one e-liquid outlet is connected to the heating chamber. The main body further includes a mouthpiece connected to and communicating with the heating chamber; when a user inhales smoke or vapor through the mouthpiece, the e-liquid is sucked from the e-liquid chamber into the e-liquid channel by a suction force, flows into the heating chamber.

Abstract: An isolation member for an atomizer includes a main body and a pull rod connected to the main body to drag the main body to move. The main body includes a hollow channel.

Abstract: An atomizer includes an e-liquid tank and a seal member. The e-liquid tank includes a cavity and an airflow channel. The seal member is disposed on one end of the e-liquid tank. The seal member includes a groove configured to equalize a pressure in the e-liquid tank with outside pressure. Both ends of the groove communicate with the cavity and the airflow channel, respectively.

Abstract: An atomizer includes a heating assembly, a first e-liquid collector, and a second e-liquid collector. The first e-liquid collector and the second e-liquid collector are disposed under the heating assembly. The first e-liquid collector is configured to store condensed e-liquid; and the second e-liquid collector is configured to store the condensed e-liquid overflowing out of the first e-liquid collector. The first e-liquid collector is disposed near the heating assembly.

Abstract: An atomizer includes an e-liquid tank. The e-liquid tank includes an e-liquid chamber and an air vent communicating with the e-liquid chamber.

Abstract: An atomizer includes an elastic member. The elastic member includes an atomization core, a support base, an air regulation ring, and a seal ring. The support base includes an e-liquid inlet. The atomization core is disposed on the support base to atomize e-liquid. The seal ring is disposed in the support base and below the atomization core. The air regulation ring is disposed around the support base; when the air regulation ring is pulled down, the atomization core is ejected from the top of the atomizer for replacement, and the e-liquid inlet of the support base is automatically sealed by the seal ring so that no e-liquid leaks out of the atomizer.

Abstract: An electronic cigarette including an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The battery assembly includes an air column and a plate including a pneumatic switch. When in use, airflow passes through the air column to drive the plate including the pneumatic switch to work. The air column and the plate are disposed on the top end of the battery assembly, and the air column is staggered with the plate thus preventing an e-liquid from flowing onto the plate.
