▎ 摘　　要

NOVELTY - Heating device comprises a smoke pipe, which is made of conductive material, and the smoke pipe is provided with a containing cavity for placing cigarette. A heating layer covers the smoke tube, the heating layer is graphite film or graphene film, and a coating layer, covers the heat layer, and is composed of a conductive materials. The smoke tube is connected with a first electrode, the coating layer is connected to a second electrode. The first electrode is sequentially connected with the smoke tubes, the heat layers, the paint layer and the second electrode sequentially. USE - Heating device used as core component of heating non-combustion atomizing device for heating cigarette to make it generate aerosol with fragrance for use. ADVANTAGE - The device realizes high-efficient transmission of heat, so as to effectively reduce smoke waiting time, and improves structure stability of the heating device, thus preventing the structure from falling. The device avoids the condition of high cost and harsh preparation technique like aluminum-based thick film heating body, avoids the temperature limit caused by heat expansion matching cracking in the aluminum base film heating housing, and adopts the winding structure design, thus avoiding the problem of structure falling off. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a manufacturing method of heating device; (2) an electronic atomization device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a heating device. 100Heating device 110Smoke pipe 120Heating layer 130Coating layer
