Abstract:
     The present invention includes:power supply, air exhaust fan, automatic detector, alarm and their driving (control) circuits. Its power supply circuit is used for supplying power for all components in the gas water-heater, and when the induction combustion chamber of said gas water-heater is burning normally, the automatic detector circuit is used to drive the driving circuit of the air exhaust fan to make the air exhaust fan work to forcedly exhaust the waste gas of water-heater. Besides, it also possesses an air-driven perception switch, after the air exhaust fan circuit is powered, it can detect that the air exhaust fan is started normally or not, and if the air exhaust fan is not started normally, it can start the alarm circuit, make the alarm elements of buzzer, etc. sound to warn user.
