▎ 摘　　要

NOVELTY - The chip has a heating layer (2) uniformly coated on a surface of an insulating layer (1). A conductive layer (3) is fixed on an edge of the heating layer. A wear-resistant layer (4) is paved on the surface of the heat dissipation layer and covers the conductivity layer. An insulation layer (5) is laid on the face of the wear-wear layer. The heating layer is composed of multiple heating areas. Thickness of the multiple heating area is different. USE - Laminated graphene safety heating chip for use in a physical therapy mattress technical field of a human body. ADVANTAGE - The graphene-superposed safety heating chip has fast heating speed, high power stability and so on, the far infrared body generated at the same time has different curative effect, the graphene heating chip is provided with good application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the laminated graphene safety heating chip and manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the graphene heating chip structure.
