▎ 摘　　要

NOVELTY - Graphene far-infrared negative ion soft heater comprises an upper shaft, a lower shaft, and a heating body, where two ends of the heating body are fixedly connected to the upper shaft and the lower shaft, respectively. The heating element has a layered structure, where the layered structure of the heating element includes a flame retardant and waterproof layer, a negative oxygen ion generating layer, an insulating layer, a fixed layer, a graphene heating layer, another fixed layer, another insulating layer, another negative oxygen ion generating layer, and another flame-retardant and waterproof layer. The graphene heating layer is connected to a power supply device through a wire. USE - Graphene far-infrared negative ion soft heater used for temperature adjustment, air purification or far-infrared in an indoor or planting greenhouse physiotherapy (claimed). ADVANTAGE - The graphene far-infrared negative ion soft heater has functions of purifying air and physiotherapy decorative, which makes up for the defect of the poor appearance of the heater generally. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene far-infrared negative ion soft heater, which involves: (A) using graphene to prepare a graphene heating layer; (B) spreading the molten hot-melt adhesive on one side of the graphene heating layer to press into a fixed layer; (C) laying the insulating layer prepared in advance on the fixed layer for performing hot pressing synthesis to obtain an intermediate body of the heating element; (D) spreading the molten hot-melt adhesive on the other side of the graphene heating layer to press into another fixed layer; (E) laying another insulation layer prepared in advance on the fixed layer to perform hot pressing synthesis to obtain another intermediate body of the heating element; (F) preparing negative oxygen ion generating layers on the two surfaces of the intermediate to obtain a third intermediate of the heating element; and (G) spraying flame-retardant and waterproof layer on the two surfaces of the third intermediate body to obtain the final heating element.
