NOVELTY - The utility model model belongs to the technical field of tobacco heating especially relates to a heating device and electronic cigarette, comprising a valve metal base and graphene heating body, valve metal base is surface with a micro-arc oxidation of the insulating layer; the graphene heating body is set on the valve metal base body, the graphene is set on the heating body, the electrode is used for connecting the power supply, so that the graphene heating body is electrified and generates heat. When the heating is used, inserted into the cigarette, and then connected with the external power supply through the electrode, the graphene heating body is electrically conducted, the graphene heating body is transmitted to the valve metal base body and transmitted to the tobacco, the heat on the valve metal base is also transmitted to the tobacco, so as to realize the heating of the tobacco and smoke, The heating device uses graphene as heating material, the speed can heating the electronic cigarette realize the opening and closing, the user does not need to wait for a longer time, and the technical difficulty of the valve metal surface set with the graphite DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic cigarette.
