NOVELTY - The utility model claims a concave-convex heating plate, comprising an insulating layer, the bottom of the insulating layer is provided with heating body, the of the heating body is provided with a conductive material attached base material, the top part of the insulating layer is provided with a concave-convex point, the concave-convex point is made of transparent material, the convex surface of the concave-convex point is arc-shaped surface design, the top of the concave-convex point is designed with concave surface; the concave surface is V-shaped, the top view is circular, the heating body adopts graphene or carbon crystal or carbon element resistance light amplitude heating, which is coated or cloth or paper, 4-16um the far infrared light wave; The utility model relates to the technical field of heating plate. The concavo-convex heating plate solves the problem that the existing direct far infrared heating plate irradiates the face, which will cause the face of the direct light wave to be heated quickly, the two sides of the cheek of the direct light wave are heated slowly, the heating is not uniform, affecting the user experience and beautifying physical therapy effect.
