Fire extinguisher with escape indication

A fire extinguisher with escape indication comprises an auxiliary safety device and a fire extinguisher. The auxiliary safety device comprises: a detecting unit mounted on a fastening base, a temperature sensor for sensing the ambient temperature around the fastening base and transmitting temperature data, a gas sensor for sensing the gas concentration around the fastening base and transmitting concentration data, a control unit further provided with a network transmission module for transmitting the temperature signal and the concentration signal based on the temperature data and the concentration data to an external control center, and a first battery unit for supplying the power required by the detecting unit, the temperature sensor, the gas sensor and the control unit. The body of the fire extinguisher may be detachably mounted on the fastening base. When the fire extinguisher is detaches from the fastening base, the detecting unit will drive the control unit to transmit the control signal to the external
