NOVELTY - The utility model claims a graphite heating film capable of preventing tripping, comprising two side edges of the graphene film main body, a graphene film provided with a positive electrode and a negative electrode separated graphene film main body front and back surfaces provided with first PET film and the second PET film layer. the first PET film layer is coated with a conductive paint, conductive paint from the first PET film layer located on the side of the above negative electrode to the positive electrode above the side coating and does not cover above the positive electrode, the positive electrode and negative electrode leads out two leads and two leads placed in the same interface. on the first PET film layer is covered on the graphene film heating body coated with conductive paint, conductive paint covers the cathode upper end and does not cover over the anode, the first PET film layer on sensing electronic return to graphene heating film main body, prevent the first PET film layer graphene heating film main body is covered on the electronic accumulating more and more so as to cause tripping of the whole circuit.
