NOVELTY - The utility model claims an intelligent temperature control cold-proof waistcoat for calf and lamb, the waistcoat main body is composed of a thickened wearable layer, a silver-carrying antibacterial heat preservation layer, a heating layer, a circuit structure layer and a thickened wearable surface layer sequentially overlapped from top to bottom, the heating layer comprises an insulating substrate layer, graphene partition layer, an electrode layer and an insulating layer, the graphene partition layer comprises a heating area graphene a laser etching line, graphene heating area is arranged in parallel by the laser etching line sequentially and the two ends are vertical to the electrode layer; The utility model uses the electric heating effect graphene the heating area to heat, through the silver-carrying antibacterial heat preservation layer to the heat to resist cold, and because the heating layer is not directly contact the surface, and graphene heating, the heat is uniformly distributed and transmitted, it will not bring uncomfortable feeling, it ensures the comfortable feeling, The special heating way of the stone black makes the safety of the product higher, the service life is longer, it is more environment-friendly to the environment.
