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: A high-frequency heating device, includes: a housing, a thermal insulation cup, and a magnetic induction coil. The housing includes a cavity and the magnetic induction coil is disposed in the cavity. The thermal insulation cup is nested in the magnetic induction coil.

Abstract: An atomizer includes a housing, a partition wall, a heating core, and an e-liquid accumulation part. The housing includes an e-liquid chamber and a heating chamber. The partition wall is disposed between the e-liquid chamber and the heating chamber to separate the e-liquid chamber and the heating chamber. The partition wall includes at least one e-liquid inlet. The heating core is disposed in the heating chamber and opposite to the at least one e-liquid inlet. The e-liquid accumulation part is disposed in the e-liquid chamber, so that the e-liquid is accumulated and directed to the at least one e-liquid inlet. The e-liquid accumulation part communicates with the heating chamber through the at least one e-liquid inlet.

Abstract: An electronic cigarette includes a microwave heating module and an aerosol generator. The microwave heating module includes a cup, a cylindrical shielding net, a magnetron, and a microwave source. The cup is fixed in the cylindrical shielding net for accommodating a tobacco material. The cylindrical shielding net is disposed above the microwave source. The magnetron is disposed on the microwave source. In a power-on state, the magnetron emits microwave. The microwave is released via the microwave source into the cylindrical shielding net to heat and atomize the tobacco material in the cup. The microwave heating module is disposed in the aerosol generator.

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: A tobacco roaster includes a heating rod which is retractable. The heating rod includes a through hole and an air passage communicating with the through hole. The heating rod is configured to heat a tobacco material to produce smoke, and the smoke enters the air passage via the through hole.

Abstract: An electronic cigarette includes a preheater. The preheater includes an e-liquid tank and a heating wire disposed in the e-liquid tank. In a power-on state, the heating wire produces heat.
