NOVELTY - The utility model claims a far infrared emitting source and far infrared electric heating patch. the far infrared emitting source (2) comprises a graphene electric heating film and a temperature detector (4), the graphene electric heating film comprises graphene and electrode set on the surface of the graphene, the probe of the temperature detector (4) is connected with the graphene electric heating film. the far infrared electric heating patch comprises a heat conducting insulating layer (3); a far infrared emitting source (2) and a bonding layer (5), the far infrared emitting source (2) is located in the heat conducting insulating layer (3); the far infrared emitting source (2) comprises a lead (8), the lead (8) passes through the heat conducting insulating layer (3), the bonding layer (5) is located at the bottom of the electric heating patch. The utility model connects the temperature detector and the graphene electric heating film; directly measuring the temperature of the graphene electric heating film; the control of the temperature of the patch is more accurate. The far infrared electric heating patch of the utility model can be used repeatedly after being washed by water.
