[0004] The existing common electric heating film module structure is heating film, connecting wire, power supply and monitoring module, wherein the connecting wire is an ordinary metal wire, and the connection methods of the connecting wire and the power supply and monitoring module include snap-in type, tin welding type, over Hole rivet type; the electrothermal film, the power supply and the monitoring module are connected together by connecting wires through snap-in fasteners or through-hole rivets and direct welding to form a complete electrothermal film module, and the electrothermal film module is generally used for clothing heating , shoulders / knees / waist / neck etc. are in contact with the human body, and are connected in the form of connecting wires and crimping terminals. The crimping will always form a raised structure, which will cause product deformation and the overall shape is not coherent enough. At the same time, the connection of the connecting wire will also increase the additional process, increase the production cost of the product, and at the same time, the additional process will also cause a certain proportion of defective products; and the welding method will have obvious welding bumps on the surface, which will also cause the surface of the electric heating film to be damaged during welding. Pollution, poor overall appearance;

[0005] Invention patent CN206118057U Household products with graphene heating film describes a kind of electric heating film module product suitable for household products. Its electrodes are connected with power supply and control system by using metal wires. It itself does not apply to the requirements of people who are increasingly pursuing comfort, beauty, and simple operation;

[0006] Invention patent CN2750611 flexible heating film outlet packaging structure introduces a flexible heating film outlet packaging method, which effectively protects the connection at the outlet of the flexible heating film and improves the insulation and sealing of the outlet at the flexible heating film, but There will be two obvious raised welding points at the outlet. If worn on the human body, the raised points will affect the comfort of wearing
