Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of household appliances, and particularly relates to an electric heater. Background Art
[0002] The main problem with existing electric heater technology is that its temperature control mechanism relies on manual operation by the user and lacks intelligent adjustment, making it prone to overheating due to negligence or misoperation. Users are required to turn the heater on, off, or adjust the temperature manually. However, when the heater is running for extended periods of time or in high power mode, a large amount of heat accumulates inside the device. If the user fails to turn the device off promptly or sets the temperature too high, the heater may continue to run, causing damage to internal components due to the high temperature.
[0003] This situation not only shortens the lifespan of the device itself, but can also lead to more serious safety hazards, such as short circuits and fires caused by overheating. Especially when users forget to turn off the device, the heater may remain on for extended periods, continuously generating heat, further increasing the internal temperature and the risk of component damage.
[0004] On the other hand, existing electric heaters often have simple heat dissipation designs, relying primarily on natural cooling or inefficient fan systems. These methods are unable to quickly dissipate the large amounts of heat accumulated during operation, causing the internal temperature of the device to continue to rise. This inadequate heat dissipation makes the heater prone to overheating after prolonged use, further deteriorating the device's operating conditions.

During use, after the device is powered on, the control circuit board 40 drives the infrared heating component 20 to start working, and the device starts to radiate heat outward. As the device continues to work, the temperature sensor 50 will monitor the internal temperature in real time. When the temperature reaches the set warning line, the temperature sensor 50 is closed and sends a signal to the control circuit board 40. After receiving the signal from the sensor, the control circuit board 40 starts the heat dissipation fan 30, so that the fan starts to run, and the internal heat is taken away by air flow, thereby reducing the temperature inside the device.
