An electric heating noncombustible cigarette device comprises a cavity, a control circuit segment and a battery segment. A cylindrical tobacco inserting cavity comprising a hole distribution plate is formed in the cavity through an annular upper cover, a resistance wire is spirally wound on the hole distribution plate, the lower end of the resistance wire is connected with a control circuit, a conductive sliding rod is arranged in the cavity, the bottom end of the conductive sliding rod is connected with the control circuit, a vertically movable metal sliding vane is arranged on the conductive sliding rod, one end of the metal sliding vane contacts with the resistance wire wound on the hole distribution plate, the other end of the metal sliding vane extends out of the cavity through a slit formed in the wall of the cavity and is connected together with an insulating nut, the insulating nut is pulled to change the contact position of the metal sliding vane and the resistance wire, so that the resistance value of the resistance wire is controlled, and gradient heating distillation of tobacco materials in the tobacco inserting cavity from low temperature to high temperature is realized. By the aid of the device, tobacco products are sucked, the smoking quality of noncombustible cigarettes can be improved, and the use ratio of the tobacco materials is increased.
