NOVELTY - The utility model model claims an electric floor heating insulating structure based on graphene heating chip, comprising a bottom supporting plate, the inner part of the bottom supporting plate is fixedly connected with a first cavity, the upper surface of the bottom supporting plate is fixedly connected with a supporting block, the upper surface of the supporting block is provided with a cover plate, the cover plate, a second cavity is formed between the supporting block and the bottom layer supporting plate; the top inner wall of the second cavity is provided with a heat absorbing material, the upper surface of the bottom supporting plate is provided with a reflecting layer. The utility model model is designed with a reflecting layer, a bottom supporting plate, a cavity, in the process of the device operation, the heat is reflected in the way of heat radiation, avoiding the loss of the bottom heat, designing cover plate, supporting block, vertical supporting rod and the horizontal supporting piece, realizing the supporting ability of the device, avoiding the phenomenon of cement hollow drum, by designing the supporting rod, supporting frame, avoiding the graphene and the ground, contact heat conduction, further reducing the heat loss of the ground.
