[0022] As shown in the figure, Figures 2-4 The double alarm assembly comprises a fixing pipe 14, a channel block 15, a second spring 16, a second alarm 17 and a second button 18, the second alarm 17 is installed at the rear side in the shell 19 through bolts, the second button 18 is connected to the second alarm 17, and the second button 18 and the second alarm 17 are electrically connected, the fixing pipe 14 is connected to the rear end of the channel pipe 9, the channel block 15 is slidably connected in the fixing pipe 14, the second spring 16 is connected between the channel pipe 9 and the fixing pipe 14, the elastic force of the second spring 16 is greater than that of the first spring 12 on the red first button 11, the second button 18 penetrates into the fixing pipe 14, and the channel block 15 moves to the rear side to press the second button 18, so as to start the second alarm 17.
[0023] In use, the heating disc 3 transfers heat to the ceramic glass panel by conduction, which in turn conducts heat evenly to the bottom of the cooking utensil placed on it, thereby achieving effective heating of the foodstuff. The temperature change during the entire heating process is monitored in real time by the temperature sensor 4, ensuring the safety and efficiency of the device operation. As the temperature of the heating disc 3 rises, the alcohol inside the connecting tube 8 and the passage tube 9 expands due to heat. Since the thermal expansion coefficient of alcohol is large, its volume increases significantly with temperature. The three first springs 12 have different spring forces. When the alcohol starts to expand and reaches a certain volume, it will first push the corresponding lifting block 13 to compress the first spring 12 at the front, and then trigger the green warning light 10 connected to the first button 11. This indicates that the current temperature is within the safe operating range and is suitable for daily cooking. If the temperature continues to rise and the alcohol continues to expand, the middle first spring 12 will be compressed, causing the yellow warning light 10 to light up. At this time, the user should be vigilant and adjust the heat or take other measures to prevent the temperature from rising too high. When the temperature further rises and reaches or exceeds the set warning value, the rear first spring 12 is compressed, and the red warning light 10 is lit, indicating that the device has entered a high-temperature state and there is a risk of overheating. The user is advised to check immediately and reduce the power or turn off the power. These warning lights 10 not only provide a visual temperature reference for the user, but also ensure that the first button 11 can be automatically reset when the temperature drops and the alcohol contracts, ensuring the cyclic usability of the system. Once the temperature exceeds the safe range, the red warning light 10 is lit and the temperature is still rising. The alcohol in the passage tube 9 will continue to expand until the passage block 15 moves backward and compresses the second spring 16, and touches the second button 18, activating the second alarm 17. The second alarm 17 emits a more obvious audible and visual alarm, aiming to remind the user to take immediate action to avoid potential safety hazards. At the same time, the high-temperature signal detected by the temperature sensor 4 is also transmitted to the controller 7, which determines whether the first alarm 6 needs to be started according to the preset threshold value, and synchronously lights up the warning light 5. The combination of the first alarm 6 and the warning light 5 provides additional visual and audible cues, enhancing the user's alertness and ensuring that abnormal situations can be noticed in time even in noisy environments. When the first alarm 6 or the second alarm 17 is activated, the user should immediately stop the current operation and check the status of the electric ceramic stove. If the temperature is found to be abnormally high or there are other safety hazards, the power should be turned off in time, and after the device cools down, troubleshooting or maintenance can be performed. This double alarm mechanism greatly improves the safety performance of the electric ceramic stove, providing a reliable protective barrier for the user.
[0024] The above merely is preferred implementation manner of the present application, it should be pointed out, for ordinary skilled person in the technical field, on the premise of not departing from the principle of the present application, can also make several improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the present application.
