NOVELTY - The utility model claims a mask heating core, comprising a hot-pressing double-face sleeved mask outer shell; the inner cavity of the mask outer shell is orderly provided with a silica gel inner lining layer one from front to back; graphene heating layer and silica gel inner lining layer two; the side of silica gel inner lining layer I and silica gel inner lining layer II are provided with three buckling holes matched with each other; the other corner of the silica gel inner lining layer I and silica gel inner lining layer II are provided with. The utility model through adding three-layer lining in the inner respectively of the mask, using the button power supply is heating power supply, and under the action of the heating wire action of the graphite and graphene heating sheet, using electric heating and heat conducting performance of graphene to heat the mask, which can make the wearer use under the condition of low temperature; On one hand, it ensures the comfort of wearing; on the other hand, the face of the wearer is kept warm; the face of the wearer is prevented from being frostbite, so as to ensure the working efficiency of the wearer.
