The invention provides a fire extinguisher with a networking monitoring function, and belongs to the technical field of fire extinguishers. The fire extinguisher with the networking monitoring function comprises a fire extinguisher body, a pressure detection part, a temperature detection part, a first GPS sensor, a battery, a wireless charging unit, a coulometer, a first control unit, a remote monitoring terminal and a first communication unit. According to the fire extinguisher, the first control unit sends first real-time pressure, real-time temperature, initial operation time and real-timerunning time to the remote monitoring terminal through the first communication unit, pressure and temperature of the fire extinguisher body are remotely monitored, a real-time residual capacity of thebattery is detected by the coulometer ,the first control unit controls the wireless charging unit to charge the battery when the real-time residual capacity is smaller than a first preset residual capacity, the first control unit controls the wireless charging unit to be off when the real-time residual capacity is larger than a second preset residual capacity, so that the charging efficiency is high, and the method is convenient and rapid.
