[0070] For example, the single-chip microcomputer includes an IO (Input and Output) port, which is electrically connected to the base B of the transistor Q1 through the IO port. A resistor R1 with a resistance of 4.7K is also provided between the single-chip microcomputer and the transistor Q1. It can be understood that the present application does not limit the resistance of the resistor R1, and for example, the resistance may be 2K, 3K, 3.5K, 3.6K, 5K, etc. For example, Fig. 9 As shown, a manual recovery temperature control switch U4 is further provided between the heater 103 and the temperature protection switch 1011. By controlling the manual recovery temperature control switch U4 to be closed or opened, the heater 103 is controlled to work normally or stop working.

[0071] In some embodiments, when the heater 103 is heating normally, the single chip microcomputer outputs a low level to the base B, the emitter E and the collector C are not conducting, the electromagnet 101311 is not energized, the movable iron core 101321 is in the first position, the reset portion 10111 is in the third position, and the movable iron core 101321 and the reset portion 10111 are spaced apart along the first direction X. When the temperature of the heater 103 exceeds a preset value, the reset portion 10111 is heated and pops up to the fourth position along the first direction X to disconnect the temperature protection switch 1011, thereby disconnecting the heating circuit and stopping the heater 103 from working.

[0072] In some embodiments, see Figure 2a , Figure 3 , Fig. 9 When the heater 103 needs to continue heating, the operation button 143 is pressed, so that the single chip microcomputer outputs a high level to the base B, the emitter E and the collector C are turned on, the electromagnet 101311 is energized, and the movable iron core 101321 moves toward the reset part 10111 to the second position in the first direction X, driving the reset part 10111 to move to the third position, and the movable iron core 101321 abuts against the reset part 10111 along the first direction X. After releasing the operation button 143, the single chip microcomputer outputs a low level to the base B, the emitter E and the collector C are not turned on, the electromagnet 101311 is not energized, and the movable iron core 101321 moves to the first position away from the reset part 10111 in the first direction X. At this time, the reset part 10111 still remains in the third position until it overheats again and pops up to the fourth position. In this embodiment, although manual intervention is required to operate the operation button 143, compared with the complex mechanical reset mechanism in the prior art, it still has the advantages of simple operation and low cost, and does not have the problems of easy jamming and unsmooth operation caused by the mechanical structure.

[0073] In some embodiments, see Figure 2a , Figure 2b , Fig. 9The heating device includes a temperature sensor (not shown in the figure), which is arranged inside the heater 103 or on the outer surface of the second shell 1031, and is used to obtain the temperature value of the heater 103. The temperature sensor is electrically connected to the first driving part 1012. The first driving part 1012 can drive the pressing device 1013 to switch between the first position and the second position according to the temperature value of the temperature sensor; when the temperature value is not higher than the preset value and the temperature protection switch 1011 is closed, the first driving part 1012 drives the pressing device 1013 to be in the first position; when the temperature value is not higher than the preset value and the temperature protection switch 1011 is disconnected, the first driving part 1012 drives the pressing device 1013 to be in the second position.

[0074] Exemplarily, when the heater 103 is heating normally, that is, when the temperature sensor detects that the temperature of the heater 103 does not exceed the preset value and the single-chip computer detects that the temperature protection switch 1011 is closed, the single-chip computer outputs a low level to the base B, the emitter E and the collector C are not conducting, the electromagnet 101311 is not energized, the movable iron core 101321 is in the first position, the reset part 10111 is in the third position, and along the first direction X, the movable iron core 101321 and the reset part 10111 are spaced apart.

[0075] When the temperature sensor detects that the temperature of the heater 103 exceeds a preset value, the reset portion 10111 is heated and pops up to the fourth position along the first direction X to disconnect the temperature protection switch 1011, thereby disconnecting the heating circuit and stopping the heater 103 from working.

[0076] When the temperature sensor detects that the temperature of the heater 103 does not exceed the preset value and the single-chip computer detects that the temperature protection switch 1011 is disconnected, the single-chip computer outputs a high level to the base B, the emitter E and the collector C are turned on, the electromagnet 101311 is energized, and the movable iron core 101321 moves to the second position toward the reset part 10111 in the first direction X, driving the reset part 10111 to move to the third position, and the movable iron core 101321 abuts against the reset part 10111 along the first direction X. When the single-chip computer detects that the temperature protection switch 1011 is closed, the single-chip computer outputs a low level to the base B, the emitter E and the collector C are not turned on, the electromagnet 101311 is not energized, and the movable iron core 101321 is in the first position. At this time, the reset part 10111 still remains in the third position until it overheats again and pops up to the fourth position. In this way, during the use of the heating device 10, no manual intervention is required, which can provide a better user experience.

[0077] In some embodiments, see Figure 5 , Fig.10 Combined with Figure 2b, the second driving part 10131 includes a cylinder 101312 or a hydraulic cylinder, and the pressing part 10132 includes a piston rod 101322. When the heater 103 is heating normally, the cylinder or hydraulic cylinder does not work, the piston rod is in the first position, the reset part 10111 is in the third position, and the piston rod and the reset part 10111 are arranged at intervals along the first direction X. When the temperature of the heater 103 exceeds a preset value, the reset part 10111 is heated and pops up to the fourth position along the first direction X to disconnect the temperature protection switch 1011, thereby disconnecting the heating circuit. When the heater 103 needs to continue heating, the cylinder or hydraulic cylinder works, so that the piston rod moves toward the reset part 10111 in the first direction X, and drives the reset part 10111 to move to the third position.
