Abstract: The present disclosure discloses an electronic cigarette, a battery thereof is connected to an atomizing device through a first power supply circuit, the battery is connected to a first detecting device through a second power supply circuit, and first information detected by the first detecting device is used to indicate whether the electronic cigarette is in a suction state. The electronic cigarette further comprises a switching key, an on-off key, a second detecting device and an MCU, the on-off key is configured for controlling the first power supply circuit to be ON and OFF, and the second information detected by the second detecting device is used to indicate the position of the switching key; the MCU controls the second power supply circuit to be ON and OFF according to the second information.

Abstract: An atomization core device has an electrode column, a liquid guiding element and a heating wire. The electrode column has a hollow liquid storage chamber. A peripheral wall of the electrode column is provided with a through-hole in communication with the liquid storage chamber. The liquid guiding element and the heating wire wrap around the outer periphery of the electrode column, and the liquid guiding element covers the through-hole. The atomization core can reduce the carbon deposition, increase the life of the heating wire, keep the original taste of the tobacco liquid, and reduce the occurrence of dry heating and leakage.

Abstract: A battery device includes a main body and a rear cover removably connected to the main body. The main body has a first battery receiving compartment. The rear cover has a second battery receiving compartment. The first battery receiving compartment is configured to receive at least two batteries while the second battery receiving compartment is configured to receive at least one battery. For the battery device, since the back cover is provided with the second battery receiving compartment cooperating with the first battery receiving compartment in the body, the apparatus applying the battery device has at least two supportable power levels. In this way, the battery device can be switched between a low power and a high power, eliminating the need of another battery device.

Abstract: An atomizing head is disclosed, including a heating component, a liquid absorption component and at least one contact ring, wherein the liquid absorption component is wrapped around the outer circumference of the heating component, the contact ring includes a base and a first clamping flange extending at a certain angle from an circumferential edge of the base, the base covers one end of the heating component in an axis direction of the heating component, the first clamping flange presses against an outer surface of the liquid absorption component to fasten the liquid absorption component onto the heating component.
