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.
