Wireless domestic gas combustion protector

The utility model relates to a wireless domestic gas combustion protector. A protection system is formed from the assembly a gas detecting emitter which is in alone placement and an electromagnetic gas flow valve which is in series connected to a gas pipeline alone via a radio wave. An attached emitting module of the gas detecting emitter which is in alone placement and an acoustic-optic element are respectively connected to different output connection points of an oscillation integrated plate in series, and is connected to a control circuit via a gas sensing element in series. Once the gas leakage or accidental fire and smoke occur, an acoustic-optic wave signal is output; an electromagnetic coil of the electromagnetic gas flow valve is connected to a normally opened control circuit of a receiving module in series. The utility model has the advantages that the system is formed from the gas detecting emitter and the gas flow valve via radio wave transmission and reception, the connection of a circuit is not needed, and the installation is more convenient; the electromagnetic gas flow valve adopts a replaceable DC battery as a working power supply, a spark can not be generated and the use is safer.
