[0002] With the advancement of technology, people have higher and higher requirements for the quality of home life. In cold seasons, electric blankets are widely used in homes, offices and other places as a heating device. However, traditional electric blankets mainly generate heat through electric heating wires, which has the problems of uneven heating, uncomfortable feeling of heat, and electromagnetic radiation that may be generated by long-term use. These problems have affected the user experience to a certain extent.

[0003] In recent years, with the continuous development of new material technology, graphene materials have been gradually applied to the home textile industry due to their excellent thermal conductivity and far-infrared emission capabilities. Some heating blankets using graphene materials have appeared on the market. However, these products still have certain shortcomings in terms of heating uniformity, comfort, safe voltage control, and the specific benefits of far-infrared heat energy to human health.

[0004] In particular, the existing graphene heating blanket has a long way to go in terms of the preparation process, and the bonding strength between the fabric and the heating sheet needs to be improved, and the problem of easy falling off still exists. At the same time, although the far-infrared heat energy of graphene has certain health benefits for the human body, the research and application of this characteristic in existing products is not in-depth enough, and there is a lack of clear explanation and effective utilization. Summary of the invention
