Thin and light heating neck guard

The invention discloses a thin and light heating neck guard. The thickness of the thin and light heating neck guard is smaller than or equal to 15 mm. The thin and light heating neck guard sequentially comprises an inner surface layer 1, a heat conducting layer 2, a heating film 3, a supporting layer 5 and an outer surface layer 7 from inside to outside. All the layers are tightly attached to form the heating neck guard, the inner surface layer 1, the heat conducting layer 2, the heating film 3 and the outer surface layer 7 are all of a flexible deformable structure, and the shape of the heating neck guard is fixed through the supporting layer. On the basis of analysis research of graphene heating characteristics, graphene is ingeniously applied to the neck guard, the problems that an existing neck guard is thick and heavy, inconvenient to move and limited in use are changed accordingly, and the neck guard which is thin and light, capable of being folded at will and capable of achieving an infrared physical t
