In a kitchen where the gas safety device of the present embodiment is not installed, gas passes through the gas inlet pipe 91 and the flow meter 92 to the gas stove 93, and a valve is also installed at the gas inlet pipe 91 to control connection and disconnection of the gas inlet pipe, but the valve is usually a manual valve and needs to be manually closed, and there is no device specially for detecting the gas concentration, so the valve is often manually closed when the gas concentration exceeds the standard seriously, but the time is late.
In the kitchen where the gas safety device in this embodiment is installed, the gas inlet pipe 91 is installed with a gas main switch 32, which is connected to the control module 1 (not shown in fig. 5), and the gas main switch 32 is a solenoid valve, and can be controlled by the control module 1 to open or close. Since natural gas is used here, the sensing device 2 and the spraying device 313 are installed on the ceiling so as to sense the gas concentration in the air and to spray nitrogen or carbon dioxide, and the alarm device 33 may be installed on the wall surface and near the ground surface.
Since the explosion limit of natural gas is 5% -15%, in this scenario, the control module 1 may set 3 thresholds, for example, 2%, 5%, and 15%, and according to different thresholds, the alarm device has four different operating states.

It should be noted that the threshold values are only exemplary, and do not necessarily represent that the threshold values and the levels of the alarm device 33 are not necessarily set, and in practical applications, a user may set the threshold values and the levels of the alarm device 33 according to different requirements, for example, the gas concentration may be at the explosion limit as the most dangerous condition, at the highest alarm level, and at the same time, only two threshold values may be set, or the gas concentration exceeds 1%, i.e., the gas main switch 32 is turned off, and the like, which are not limited in this embodiment. On the other hand, when the gas concentration is reduced to below 2%, the control module 1 controls the gas main switch 32 to be opened, and the spraying device 31, the alarm device 33 and the explosion-proof exhaust device 34 are closed, so that the gas is normally used.
