NOVELTY - The utility model claims an electric heater, comprising a base and a heating pipe; the upper part of the base is provided with an upper and a lower heat insulation layer and the surface is coated with a graphene layer of the heat conducting sleeve; the lower heat insulating layer respectively with two ends of the heat conducting sleeve to form a sealed heat conducting cavity to cover the heating pipe; the heating pipe is electrically connected with the electric control unit set in the base; the heat generated by the heating pipe and the heat absorbed by the heat conducting sleeve are accumulated in the heat conducting cavity; at the same time, the heat conducting sleeve can block the air to take away the heat, and reduce the heat loss; Therefore, the temperature in the heat conducting cavity can be quickly increased; On the other hand, the graphene has the function of enhancing far infrared emission rate; therefore, the heat of the heat conducting cavity and the heat conducting sleeve quickly radiate outwards under the action of the graphene layer; the temperature around the electric heater is quickly increased; Further, the upper and lower heat insulation layer blocking the far infrared radiation to the upper and lower ends of the electric heater, which is good for the far infrared ray radiated from the heat conducting sleeve to diffuse in parallel to the outside in the form of heat, which is more beneficial for warming.
