[0027] In this embodiment, the graphene heating layer 13 disposed within the pad 10 can be heated by the heating element 20 to melt the snow. The heating principle of the graphene heating layer 13 is that under the action of an electric field, the carbon molecular clusters in the graphene heating layer 13 undergo Brownian motion, and the carbon molecules undergo intense friction and collision. The heat energy generated is transferred to the outside in the form of far-infrared radiation and convection. The action of the carbon molecules causes the system surface to heat up rapidly, thereby achieving the purpose of heating up the temperature to melt the snow.

The first wire 22 and the second wire 23 are respectively connected to both ends of the graphene heating layer 13. In this embodiment, the connection of the first wire 22 and the second wire 23 forms a circuit, which heats the graphene heating layer 13 when energized.

[0032] In one embodiment, the graphene heating layer 13 is a graphene heating film, which is encapsulated within the insulating protective layer 11.
