▎ 摘　　要

NOVELTY - The graphene electronic heating device has an electronic graphene heating cavity that is provided with layer graphene which is provided with the conductive circuit. A conductive electrode is connected with the conductive conductor. The material of the ceramic layer comprises zirconium oxide. The conductive circuit is embedded in the inner unit of the graphene. The outer side of the ceramic layer is orderly provided with a heat-insulating layer and a third insulating layer. The conductive circuit is provided between the graphene layer and the ceramic layer. The material of the heat-insulating layer comprises gas, and the material of the third insulating layer comprises Teflon. USE - Graphene electronic heating device for use in an electronic cigarette atomizing assembly of electronic smoking set for heating an object to be burnt in a cavity and set with Teflon (RTM: Polytetrafluoroethylene) layer and ceramic layer. ADVANTAGE - The graphene electronic heating device provides the Teflon layer and a ceramic layer which are provided which realize the continuous and stable combustion of the object to be burned in the accommodating cavity, without the diffusion of peculiar smell, and at the same time increases the use time of the graphene electronic heating device under the same energy storage condition. The preparation method is simple, the process control is convenient, and the product quality is stable, which is conducive to large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for providing preparation graphene electronic heating device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene electronic heating device. Preparation method (1) First insulating layer (2) Graphene layer (3) Second insulating layer (4) Ceramic layer (5) Assembly (6) Combusted object (7) Shell (8)
