When the smoke alarm and the temperature detector alarm at the same time, the air pump starts, and the air pump blows gas into the fire extinguishing dry powder box, and then starts the nozzle. The nozzle flows the fire extinguishing dry powder and gas mixture in the fire extinguishing dry powder box into the connecting pipe, and then enters the installation pipe from the connecting pipe. Finally, the dry powder is sprayed out from the nozzle, and the dry powder covers the burning object to extinguish the fire.
