The present invention relates to an electric flue-cured tobacco. It includes a storage tank filled with extractant and an atomization device. The electric flue-cured tobacco also comprises a device for flue-curing tobacco, which includes a heating mechanism and a heated chamber for loading cigarette or tobacco. The heating mechanism comprises a heating element and a heater circuit for controlling the heating element to be heated to a setting temperature range. An inlet of the heated chamber is connected to an outlet of the atomization device, and its outlet is connected with an opening for suction nozzle. When the electric flue-cured tobacco is working, the extractant is atomized by the atomization device and then guided into the heated chamber. The heat produced by the heating element is applied to the cigarette or tobacco in the heated chamber to generate nicotine. The nicotine and atomized extractant are mixed together and then sucked out through the opening for suction nozzle. By adopting the structure mentioned above, since the nicotine in the form of atomization can be easily absorbed by the lung, most of the gas that smokers blow off is the extractant. Therefore, the environmental pollution and passive smoking for people around can be reduced. On the other hand, it can satisfy smokers' taste.
