NOVELTY - The invention claims a graphene heating plate of layered temperature control conversion, belonging to the technical field of graphene heating device. A graphene heating plate of layered temperature control conversion, comprising a graphene heating plate, a temperature sensor and a controller, the controller can set the temperature upper limit, when the temperature sensed by the temperature sensor reaches or exceeds the set upper limit temperature, the controller controls the electric loop to cut off, it can automatically control the heating temperature of the graphene heating plate, when the temperature of the plate body reaches or exceeds the set upper limit temperature, it is automatically cut off, effectively ensure the heating temperature of the graphene heating plate will not overheat, effectively avoid the surface temperature of the heating plate is too high, burn the body skin of the user, even cause fire, the inner temperature of the heating plate is too high, burning the internal component, maintenance costs of improving and shortening the service life.
