NOVELTY - The utility model claims a waterproof safe electric heating plate, comprising a side plate, a moisture-proof layer, a heat insulation layer, a supporting frame, a graphene heating layer, an insulating layer, a waterproof layer, a connection protective shell structure and a protective sleeve structure, the moisture-proof layer is paved on the lower part of the inner side of the side plate; the heat insulation layer is paved on the upper surface of the moisture-proof layer; the supporting frame is welded at the middle part of the inner side of the side plate; the graphene heating layer is embedded in the supporting frame; the insulating layer is paved on the upper surface of the graphene heating layer; the waterproof layer is paved on the upper surface of the insulating layer. The beneficial effects of the utility model are as follows: by setting the connection protective shell structure; when using, it is convenient to make the circuit connected with the graphene heating layer pass through the through hole to reach the sleeve shell for protecting use.
