When the thermal heating of mace graphene is electrified, the carbon atoms will produce Brownian motion under the action of the current, and the carbon atoms will have violent friction and collision. The heat energy generated will be transferred to the outside in the form of far-infrared radiation and convection to achieve the purpose of heating. Far-infrared light wave can produce the most effective "resonance" with the water molecule of the cell in the human body, make the capillary dilate, promote the blood circulation, strengthen the metabolism between the tissues, increase the regeneration ability of the tissues, improve the immune ability of the body, regulate the abnormal excited state of the spirit, thus play the role of health preservation. Ultra-thin graphene far-infrared thermal film has an electrothermal conversion rate of up to 99.6%, minimizing the loss. Far infrared wave heating on the ground is closer to the human body, so that the heat generated by the heating film can be more fully and effectively used. With the adjustment of intelligent temperature control, unnecessary waste can be avoided. The bottom of the product is a thermal insulation layer, and the surface can be made of plush and PVC material. The product power model is 800W/1100W/1500W/1800W
