NOVELTY - The utility model claims a graphene electric heating anti-fog glass cover for radiation therapy locating laser lamp, belonging to the field of tumour radiation therapy device. The utility model is used for graphene electric heating anti-fog glass cover of radiation therapy locating laser lamp, comprising a power supply, a laser lamp glass mask, graphene heating film, graphene heating film comprises a first insulating layer, a heating wire, a temperature sensor and a second insulating layer; the heating wire is printed on the first insulating layer; two ends of the heating wire are plated with electrodes; the temperature sensor is connected on the heating wire; the wire is led out from the two electrodes and connected with the power supply; the second insulating layer is covered on the heating line and overlapped with the first insulating layer; the graphene heating film is embedded in the laser lamp glass mask. The utility model can maintain the surface temperature of the glass mask between 25-30 degrees Celsius, will not cause condensation of water vapor in the air, and the parallel degree and the focusing of the laser almost does not exist interference, ensures the laser lamp can work normally when the air humidity is large.
