Abstract
An atomizing device includes an atomizing sleeve; a mouthpiece assembly and an atomizing assembly received in the atomizing sleeve. The atomizing assembly includes an oil obstructing ring, a supporting sleeve, a porous body being fixed between the oil obstructing ring and the supporting sleeve, a heating wire wrapping around the porous body, a screw sleeve located at an end of the atomizing sleeve, an insulated ring and an tubular electrode received between the screw sleeve and the insulated ring. An oil valve is formed between the supporting sleeve and the tubular electrode, or between the tubular electrode and the insulated ring; the oil valve is opened or closed by a movement of the tubular electrode, and the oil valve is configured as an air passage in communication with the air pipe when the oil valve is opened. An electronic cigarette using the atomizing device is also provided.
