description The invention discloses a fire extinguishing device. The fire extinguishing device comprises a shell, a gas generator, a triggering assembly and a temperature sensing assembly. The shell is provided with a containing cavity and a jet orifice communicating with the containing cavity, and a fire extinguishing agent is stored in the containing cavity; the gas generator is arranged on the shell and used for generating gas in the containing cavity when being triggered. By arranging the fire extinguishing device, when thermal runaway happens to a battery, the temperature rises, and when the temperature is higher than the preset temperature, the temperature sensing assembly is in a damaged state, the triggering assembly enters a triggering state, and the triggering assembly in the triggering state can trigger the gas generator; gas is generated in the containing cavity after the gas generator is triggered, and the pressure in the containing cavity is increased; therefore, the fire extinguishing agent in the containi
