NOVELTY - The utility model claims a self-limiting temperature-free graphene electric kang plate, the main body assembly comprises an iron plate, a first mica plate, a PTC heating body, a heat preservation plate and a second mica plate, the lower part of the outer side wall of the iron plate is integrally formed with a second mica plate; one side of the iron plate close to the inner part of the second mica plate is fixedly connected with a heat preservation plate electric kang plate using planar strip-shaped PTC self-limiting temperature graphene heating body; the heating body is nano graphene material; it has high stability, there is no volatilization, no attenuation, and PTC self-limiting temperature graphene heating body reaches the set temperature, molecular automatic separation, resistance is increased, power is reduced, realizing the control temperature, avoiding overheating, heat collecting phenomenon; the upper and lower two sides of the outer surface of the iron plate are made of high temperature resistant first mica plate and second mica plate; the high temperature glue is used for hot pressing into a whole; the heating is uniform, fast heating; Through the overheat protector, the material itself controls the temperature, the overheat protector is forced to cut off the power, the temperature is controlled doubly, and the safety coefficient is improved.
