description | The utility model belongs to the technical field of gas alarm, and specifically discloses a household gas leakage alarm device. The structure forming the device comprises a mounting shell, and a gas sensor, a signal amplifier, an audible and visual alarm mechanism, a valve shut-off circuit and a power supply are arranged in the mounting shell; an amplified signal comparator is arranged among the signal amplifier, the audible and visual alarm mechanism and the valve shut-off circuit, and the audible and visual alarm mechanism and the valve shut-off circuit are respectively connected with two output ends of the amplified signal comparator. The household gas leakage alarm device can realize separation of alarming and shutting-off of a gas valve, and effectively solves the problem that the sensitivity of the alarm device and the shutting-off of the gas valve cause disorder of the use and management work of the natural gas. |
