NOVELTY - The utility model claims an electric hair dryer ceramic heater, comprising a heat conducting insulating main body, a non-metal heating layer, and a plurality of heat exchange holes through the heat conducting insulating main body for heating the air fluid, the predetermined position of the non-metal heating layer is provided with a power supply input end of the heating loop. Compared with the past structure, the utility model has the following advantages: Using graphene as heating body, with fast heating speed, high electric heating efficiency, energy saving, uniform heating, high heat productivity and so on. At the same time, it has fast heating speed, high electric heating efficiency, 30 %-50 % than the resistance wire, 15 %-20 % more than the semiconductor heating, heating uniformly, high heat productivity and so on. The ceramic substrate has high melting point, high hardness, high strength, good chemical corrosion resistance and dielectric dielectric property, further has low cost advantage, easy to realize, and it is good for wide popularization and application.
