Referring to fig. 1, a fire alarm system of an electric heater includes: a processor 100, a heating module 200, a humidifying module 300, a sensor module 400, and a fire alarm module 500. The heating module 200, the humidifying module 300, the sensor module 400 and the fire alarm module 500 are all connected with the processor 100.

The processor 100 is used as a control core to control the operation of the electric heater;

the heating module 200 mainly functions to heat for warming, and the heating module 200 may be a heating structure such as a PTC, a heating film, a heating tube, etc.;

humidification module 300 main function be the blowout steam, carry out the humidification to the environment, well known, equipment such as electric heater when the heating is used, although can play the effect of heating, keeping warm, but can make the environment drier, human skin drier also, and humidification module 300 then can solve or alleviate this type of problem well.

The fire alarm module 500 mainly plays a role in fire danger alarm, and in the process of using the electric heater, objects around the electric heater may be burnt due to overhigh temperature of the heating module 200; and a fire phenomenon may be caused by temperature passageways of surrounding articles due to long-term use of the heating module 200, and a disaster warning may be performed by the fire alarm module 500 to issue an alarm to notify a user, so that the safety performance is higher.

The sensor module 400 is used for sensing the temperature and humidity of the current environment, transmitting signals to the processor 100, and controlling the operation of the heating module 200 and the humidifying module 300 through the processor 100.

Specifically, the processor 100 at least includes: an analog-to-digital conversion unit 110, a signal receiving unit 120, a signal sending unit 130 and a processing unit 140.
