NOVELTY - A graphene electric heating cushion, comprising a cushion main body and graphene electric heating device; the cushion main body comprises a cushion sleeve layer covered on the outer layer; a heat preservation soft core layer set in the seat cushion sleeve layer; the graphene electric heating device comprises a mobile power supply set outside the cushion sleeve layer and a graphene heating sheet set on the upper layer of the heat preservation soft core layer; the graphene heating sheet is connected with the mobile power supply through lead; the upper layer of the graphene heating sheet is further provided with a phase change energy storage layer; the phase change energy storage layer is high heat-conducting flexible composite phase change material; the lead connected between the graphene heating sheet and the mobile power supply is further connected with a thermal protection switch; the thermal protection switch is clung to one end of the graphene heating sheet; when the temperature of the graphene heating sheet exceeds the sensing temperature of the thermal protection switch; the heat protection switch will automatically cut off the electric connection between the graphene heating sheet and the mobile power supply. The utility model is added with a heat protection switch, which can prevent overheating spontaneous combustion.
