The extensive use of traditional fossil energy such as coal, oil, and natural gas has brought about problems such as energy shortages and environmental pollution. In the field of heating, traditional coal-fired and gas-fired heating methods are less efficient, and the combustion process will produce a large amount of carbon dioxide, sulfur dioxide, nitrogen oxides and other pollutants, which have a serious impact on air quality.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0022] Reference Figure 1-5, which is an embodiment of the utility model, provides a carbon fiber electric heating plate over-temperature protection device, which includes a carbon fiber electric heating plate 1, a heat preservation frame 3 is provided inside the carbon fiber electric heating plate 1, a temperature controller 4, a temperature sensor 5 and a connecting line 8 are provided in the heat preservation frame 3, the temperature sensor 5 is connected to the temperature controller 4 through the connecting line 8, a fuse 6 is provided on one side outer wall of the carbon fiber electric heating plate 1, the fuse 6 is connected to the temperature sensor 5 through the connecting line 8, a carbon fiber electric heating wire 2 is provided in the carbon fiber electric heating plate 1, and the carbon fiber electric heating wire 2 is connected to the output end of the temperature controller 4.
[0023] As a preferred embodiment, the thermal insulation frame 3 is arranged at the inner bottom of the carbon fiber electric heating plate 1 .
[0024] The temperature sensor 5 is used to monitor the temperature value of the carbon fiber electric heating plate 1 and feed it back to the temperature controller 4. The temperature controller 4 is used to control the temperature preset value of the carbon fiber electric heating plate 1 and realize the first level of temperature protection;
[0025] It should be noted that the temperature preset is set by the external remote control, that is, the temperature peak value of the carbon fiber electric heating plate 1, and the high and low degrees of the temperature preset can be adjusted and set by the external remote control;
[0026] The first level of protection refers to power reduction protection, that is, when the temperature inside the carbon fiber electric heating plate 1 reaches a preset value, the temperature controller 4 reduces the electric power of the carbon fiber heating wire to achieve the effect of lowering the temperature, thereby realizing over-temperature protection.
[0027] The fuse 6 is provided on the outer wall of the carbon fiber electric heating plate 1 as a second temperature protection device. It can be understood that when the temperature reaches the preset value, the temperature controller 4 starts to reduce the electric power of the carbon fiber heating wire. If the temperature controller 4 is damaged or the carbon fiber heating wire continues to emit high heat, the first temperature protection loses its effect, causing the current passing through the connecting wire 8 to exceed the specified value of the fuse 6, triggering the fuse 6 to work, disconnecting the connecting wire 8, and causing the carbon fiber electric heating wire 2 to lose its energy source, thereby achieving temperature protection;
[0028] It should be noted that the principle of the fuse 6 is that after the current exceeds a specified value for a period of time, the fuse generates heat to melt the fuse element, thereby disconnecting the circuit.
[0029] An indicator light 7 is provided on the surface of the carbon fiber electric heating plate 1 where the fuse 6 is located. The indicator light 7 is connected to the fuse 6. When the carbon fiber electric heating plate 1 is working, the indicator light 7 is displayed in a first color. When the first temperature protection is activated, the indicator light 7 is displayed in a second color. When the fuse 6 is blown, the indicator light 7 goes out.
[0030] The other side of the fuse 6 is connected to a power cord 9, and the other end of the power cord 9 is connected to a power plug.
[0031] During use, the temperature sensor 5 monitors the temperature value of the carbon fiber electric heating plate 1 and feeds it back to the temperature controller 4. When the temperature reaches the preset value, the temperature controller 4 begins to reduce the electric power of the carbon fiber heating wire. If the first temperature protection fails, the current passing through the connecting wire 8 exceeds the specified value of the fuse 6, triggering the fuse 6 to work and disconnect the connecting wire 8, so that the carbon fiber electric heating wire 2 loses its energy source, thereby achieving temperature protection. At the same time, the user can observe the status of the carbon fiber electric heating plate 1 according to the color change of the indicator light 7.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
