[0027] Embodiment one:

[0028] Referring to Figures 1-5 , the electronic temperature controller comprises a temperature controller body 1, one side of the temperature controller body 1 is provided with a temperature probe 2, and the temperature controller body 1 is provided with a plug-in part 11 near the temperature probe 2. The temperature controller body 1 is provided with a rotary knob type adjusting switch 3 and a display panel 4 matched with the rotary knob type adjusting switch 3. One side of the temperature controller body 1 near the plug-in part 11 is provided with a safety ejection mechanism. The safety ejection mechanism comprises an ejection piece 5 arranged towards the plug-in part 11 and a driving spring 6 for driving the ejection piece 5 to slide towards the temperature probe 2. The temperature controller body 1 is provided with a sliding groove 13 matched with the ejection piece 5. The ejection piece 5 is slidably arranged in the sliding groove 13, and one end of the ejection piece 5 can extend out of one end of the sliding groove 13 near the plug-in part 11. The temperature controller body 1 is provided with a pin body 7 arranged vertically opposite to the sliding groove 13. The ejection piece 5 is provided with a pin hole 51 engaged with the pin body 7. The temperature controller body 1 is provided with a driving mechanism for driving the pin body 7 to reciprocate transversely away from or close to the end of the sliding groove 13 and a microcontroller 8 in control connection with the driving mechanism. The microcontroller 8 is in data communication connection with the temperature probe 2. In this embodiment, the safety ejection mechanism is arranged in the temperature controller body 1, which can improve the safety of the temperature controller. When the safety ejection mechanism detects a fire or a temperature that is too high, it can drive the temperature controller body 1 to automatically separate from the electric kettle, improve the safety, avoid the spread of fire, and avoid affecting the safety of the circuit. When in use, the microcontroller 8 receives the temperature data of the temperature probe 2. When the temperature exceeds the preset threshold, it is determined that there is a fire or a fire risk, so as to control the driving mechanism to work. The driving mechanism drives the pin body 7 to retreat, the pin body 7 is separated from the pin hole 51 of the ejection piece 5, and the ejection piece 5 is ejected under the action of the driving spring 6 and abuts against the electric kettle, so as to separate the temperature controller body 1 from the electric kettle and reduce the risk.

[0029] Referring to Figure 1 , Figure 2The driving mechanism includes a drive motor 9 disposed on the outer wall of the thermostat body 1 and a drive gear 91 disposed on the rotating shaft of the drive motor 9. A rack 10 adapted to the drive gear 91 is provided at one end of the pin body 7 away from the slide groove 13. The rack 10 is disposed in the thermostat body 1 and meshes with the drive gear 91, and can reciprocate to the end away from or close to the slide groove 13.

[0030] See Figure 1 , Figure 2 There are two ejector plates 5, which are respectively located on both sides of the thermostat body 1. The drive gear 91 has racks 10 and pins 7 on both sides for cooperating with the ejector plates 5. The force is evenly distributed on both sides, resulting in a higher success rate of ejection.

[0031] See Figure 4 The thermostat body 1 also contains a battery electrically connected to the microcontroller 8 and the drive motor 9. The battery provides independent power, improving safety and preventing short circuits from causing the thermostat to remain attached to the electric cooker.

[0032] See Figure 4 The controller body 1 is also equipped with a short-circuit monitor 14 that is connected to the microcontroller 8 for data communication. In the event of a short circuit, it can automatically disconnect from the electric heating pot.

[0033] See Figure 4 The thermostat body 1 is also equipped with a buzzer alarm 15 that is electrically connected to the microcontroller 8.

[0034] Example 2:

[0035] See Figure 4 , Figure 6 and Figure 7 The thermostat body 1 is also equipped with an automatic fire extinguishing mechanism that is electrically connected to the microcontroller 8.

[0036] See Figure 4 , Figure 6 and Figure 7 The automatic fire extinguishing mechanism includes a miniature gas cylinder 16 and an electronic valve 17 controlled and connected to the miniature gas cylinder 16. The electronic valve 17 is fixedly installed on the side wall or inside the thermostat body 1, with its output end facing inwards. The miniature gas cylinder 16 is filled with carbon dioxide gas. This improves safety by triggering the automatic fire extinguishing mechanism to extinguish potential fire hazards inside the thermostat body 1 upon detecting a fire or excessively high temperature. When a fire hazard is detected, the microcontroller 8 can control the electronic valve 17 to automatically open, thereby filling the thermostat body 1 with carbon dioxide gas from the miniature gas cylinder 16 for fire extinguishing.

[0037] See Figure 4、 Figure 6 and Figure 7 The side wall of the temperature controller body 1 is detachably provided with a protective shell 18 for covering the micro gas cylinder 16 and the electronic valve 17.

[0038] Referring to Figure 4 、 Figure 6 and Figure 7 The temperature controller body 1 is provided with a second temperature sensor 19 electrically connected with the microcontroller 8.

[0039] The working process of the present application is as follows:

[0040] In the working process of the electronic temperature controller, when the microcontroller 8 receives the temperature data of the temperature probe 2, it is determined that there is a fire or a fire risk when the temperature exceeds the preset threshold, so as to control the driving mechanism to work, the driving mechanism drives the pin body 7 to retract, the pin hole 51 of the pop-up sheet 5 is separated from the pin body 7, the pop-up sheet 5 is popped out under the action of the driving spring 6, and the temperature controller body 1 is separated from the electric heating pot, thereby reducing the risk.

[0041] The above examples are illustrative of the present application, but not limiting of the present application, and any simple transformation of the present application belongs to the protection scope of the present application.
