Fire extinguishing grenades resemble "hand grenades" in shape and in use. As long as they are thrown at the source of fire, the initial fire can be quickly extinguished. When a fire extinguishing grenade is put into the fire source, the shell will burst instantly when it touches the hard object, and the high-efficiency fire extinguishing liquid will spray out immediately, forming a large and thin film covering the surface of the igniting object, isolating the object from contact with oxygen, and restraining the oxygen content near the ignition point, so as to quickly eliminate smoke and cool down, thus achieving a very good fire extinguishing effect. 。 And the fire extinguishing fluid also has the fluidity, thus effectively prevents the re-ignition.
