NOVELTY - The invention relates to an electric hair dryer with electric heater, comprising: a shell, a heating pipe and a heating component; one end of the shell is provided with an air inlet; the other end of the shell is provided with an air outlet; the heating pipe is close to the air outlet; the electric heating component is close to the air inlet; the surface of the heating pipe is coated with graphene; the surface of the heating pipe is winding with a metal wire; the metal wire and the heating component are used for connecting with the power supply. The heating pipe of the invention heats the graphene through the metal wire, the graphene generates far infrared to physically heat the air in the pipe, so as to keep the moisture in the air, compared with the pure air heating and adjusting the temperature by the heating wire; The embodiment by heating pipe coated with graphene for secondary heating the air, there is no need to use two sections of heating wire for heating, which can save electric energy.
