The invention discloses an electromagnetic launch type fire-extinguishing bomb, and belongs to the technical field of fire extinguishing and fighting. The fire-extinguishing bomb mainly comprises twoparts of an electromagnetic launch device and a fire-extinguishing bomb body, wherein the fire-extinguishing bomb body is launched to a fire area of a high-rise building by the electromagnetic launchdevice, a fire is efficiently and rapidly extinguished, the fire-extinguishing bomb body is fixedly arranged in the electromagnetic launch device through a bomb support, the electromagnetic launch device works after a switch is switched on, the electric energy in an energy storage power supply is converted into the kinetic energy of an armature to launch the fire-extinguishing bomb body, the armature and the bomb support, the armature and the bomb support are immediately dropped, the fire-extinguishing bomb body is ignited in the air to work to be close to a fire source quickly, a warhead is detonated, fire-extinguishing substances in the fire-extinguishing bomb body are dispersed on the fire source, oxygen near the fire source is absorbed or isolated, and the purpose of fire extinguishingis realized. When the fire or explosion occurs in the high-rise building, fire-fighting personnel can use the fire-extinguishing bomb for fire extinguishing and rescue, the fire-extinguishing bomb body is accurately launched to a fire place, and the fire is extinguished in time, so that the fire extinguishing efficiency is improved, and the safety of fire-fighting personnel during fire extinguishing is ensured.
