NOVELTY - Electric heater comprises a heating base, a back plate and an upper cover. The back plate is arranged on the heating base. The heating base includes a graphene heating film, a base and a reflective plate. The graphene heating film is arranged in the base and on the upper end of base. The reflective plate is placed in the inner cavity of base and is located below the graphene heating film. The lower end surface of reflective plate is close to the base. An upper cover is set on the base in a rotating manner. The upper cover, the back plate, and base form a heating cavity. The upper cover adjusts the volume of heating cavity rotatably. USE - Electric heater e.g. folding electric heater for stove. ADVANTAGE - The electric heater has simple structure, adjustable heating range and good heating effect. The reflecting plate reflects the heat to the surface of the base, thus reducing heat dissipation, enhancing heating effect, and graphene heating film of the upper cover and the base heating together to form a surrounding heating, reaching uniform heating effect and improving foot warming effect.
