[0017] The following further elaborates on the detailed embodiment of the utility model in conjunction with the drawings.

[0018] As Figures 1 to 3 shown, a PI heating film facilitating installation and temperature adjustment includes a heating area and a current input area. The heating area is used to heat by the current passing through the heating wire 2, and different amounts of heat can be generated under different current conditions.

[0019] The heating area includes a bottom film 1, a heating wire 2, an insulating layer 3, and a temperature - measuring layer 4 arranged in sequence along the height direction. The current input area is connected to the heating wire 2 through a wire 5. The bottom film 1 is used to support the heating wire 2, the insulating layer 3 is used to cover the heating wire 2 to prevent the current of the heating wire 2 from affecting the users, and the temperature - measuring layer 4 is used to measure the temperature generated by the heating wire 2 and form a closed - loop with the heating control module 7 to better control the temperature of the heating wire 2.

[0020] The current input area includes a current input terminal 6 and a heating control module 7 electrically connected to the current input terminal 6. The heating control module 7 is used to control the input value of the current. The heating control module 7 is electrically connected to the temperature - measuring layer 4, and the heating control module 7 is used to receive the temperature of the temperature - measuring layer 4 and adjust the current of the current input terminal 6.

[0021] On the side of the bottom film 1 away from the heating wire 2, there is a self - adhesive 8, and the self - adhesive 8 on the bottom film 1 is used to fix the bottom film 1 in place.

[0022] The bottom film 1 and the insulating layer 3 form a closed space, and the closed space formed by the bottom film 1 and the insulating layer 3 can concentrate the heat generated by the heating wire 2.

[0023] The heating wire 2 includes two connecting parts 9 communicating with the wire 5 and a heating part 10 arranged between the two connecting parts 9. The temperature measuring layer 4 is located directly above the heating part 10, and the temperature measuring layer 4 detects the heat generated by the heating part 10.

[0024] The heating part 10 is in a reciprocating and folding shape. The reciprocating and folding heating part 10 can make the heating space more intensive, thereby producing a better heating effect.

[0025] The bottom film 1 is provided with a limiting hole 11 penetrating through the insulating layer 3. The limiting hole 11 is used to position the bottom film 1, so that the bottom film 1 can be positioned and fixed more simply.

[0026] When the utility model is in use, the staff tears off the adhesive tape 8, and at the same time uses the limiting hole 11 to position the bottom film 1. Under the action of the adhesive tape 8, the bottom film 1 is bonded and fixed. The current is input to the current input terminal 6 through the heating control module 7. Under the action of the wire 5, the current flows to the heating part 10 through the connecting part 9. Under the action of the resistance of the heating wire 2 itself, the heating wire 2 generates corresponding heat. At the same time, the heat generated by the heating wire 2 is detected by the temperature measuring layer 4. The heat detected by the temperature measuring layer 4 is transmitted to the heating control module 7 through an electric signal. According to the action of the heating control module 7 and the temperature measuring layer 4, a closed-loop control is performed on the heating wire 2, so that the magnitude of the current can be adjusted in real time according to the heat generated by the heating wire 2.

[0027] The utility model adopts a temperature measuring layer and a heating control module to perform closed-loop control on the heating wire, so that the heating wire can be actively and real-time adjusted according to different heating temperatures, and the object to be heated can be heated better;

[0028] The utility model adopts an adhesive tape and a limiting hole, so that the bottom film in the utility model can be better positioned and fixed, thereby reducing the installation time of the staff.
