[0036] Example 1: Referring to Figures 1 to 5, this is the first embodiment of the present invention. This embodiment provides an electric heating pad with safety protection function. Most electric heating pads on the market are prone to short circuits and overheating of the heating wires during prolonged use, which can lead to fires and pose certain safety hazards. Therefore, an electric heating pad with safety protection function is needed to meet people's usage needs. It includes an electric heating pad body 1 and a power cord mechanism 2. The electric heating pad body 1 includes a base layer 101. A first protective layer 102 is adhered to the top of the base layer 101, and a second protective layer 103 is adhered to the top of the first protective layer 102.

A blanket layer 106 is adhered to the top of the insulating layer 105.

[0037] Referring to Figures 1 and 3, in an embodiment of this utility model, the heating element 1021 is installed in a meandering shape inside the first protective layer 102, and the heating element 1021 is fixedly connected to the inner wall of the first protective layer 102 by a fixing buckle. The meandering arrangement of the heating element 1021 inside the first protective layer 102 improves the heating effect of the heating element 1021.

[0038] Referring to Figures 1, 2, and 4, in the embodiment of this utility model, the interior of the second protective layer 103 is arranged with horizontal and vertical interlacing, containing only heating wires 1031. Temperature sensors 1051 are installed inside each insulating layer 105, and multiple sets of insulating layers 105 are symmetrically installed. Through the design of multiple sets of temperature sensors 1051, the temperature monitoring effect of the temperature sensors 1051 is improved.

[0039] The heat-resistant layer 104 is made of ceramic fiber and has a thickness of 0.2-0.5mm. The use of ceramic fiber in the heat-resistant layer 104 improves the heat resistance of the main body 1 of the electric heating pad.

[0040] The specific working principle is as follows: First, the first protective layer 102 is made of glass fiber, which gives it excellent high temperature resistance and flame retardancy, and can quickly absorb and disperse the heat generated by the flame. At the same time, the second protective layer 103 is made of polyvinyl chloride, which provides good protection for the heating wire 1031. Meanwhile, the heat-resistant layer 104 is made of ceramic fiber, which further enhances the heat resistance of the electric heating pad body 1.

[0041] Example 2: Referring to Figures 1 to 5, this is the first embodiment of the present invention. This embodiment provides an electric heating pad with safety protection function. It addresses the issue that most electric heating pads on the market are prone to short circuits and overheating of the heating wires during prolonged use, which can lead to fires and pose certain safety hazards. Therefore, an electric heating pad with safety protection function is needed to meet people's usage needs. The power cord mechanism 2 includes a first power cord body 201, which is fixedly installed on the side wall of the second protective layer 103. One end of the first power cord body 201 is fixedly connected to one end of the second protective layer 103.

[0042] Referring to Figure 1, in this embodiment of the present invention, a second power cord body 203 is installed on the outer wall of the first power cord body 201, and the end of the second power cord body 203 away from the first power cord body 201 is fixedly connected to the heating element 1021. A second thermostat 204 is installed on the outer wall of the second power cord body 203. The output end of the temperature sensor 1051 is electrically connected to the input ends of the first thermostat 202 and the second thermostat 204 respectively through wires. The temperature is monitored by the temperature sensor 1051, so that the temperature of the second thermostat 204 and the first thermostat 202 can be adjusted according to the temperature monitored by the temperature sensor 1051.

[0043] The specific working principle is as follows: First, through the design of the temperature sensor 1051, when the temperature of the electric heating pad body 1 reaches the preset value set by the temperature sensor 1051, the temperature sensor 1051 activates the first thermostat 202 and the second thermostat 204 respectively. This allows the first thermostat 202 and the second thermostat 204 to be adjusted or shut down, thereby quickly shutting down the electric heating pad body 1 and preventing overheating of the electric heating pad body 1, which could lead to a fire.
