Throwing type safety foam extinguisher

Abstract

The invention discloses a throwing type safety foam extinguisher which comprises a shell. A first spray head is fixedly connected to the interior of the shell, a thermal induction coil is fixedly connected to the exterior of the first spray head, a first electromagnetic valve is fixedly connected to one side of the first spray head, and a thickened bottom layer is arranged at the bottom of the shell. A switch fixing base is arranged at the middle portion of the shell. Due to the fact that the thickened bottom layer is arranged and is large in thickness and mass, when the extinguisher is thrown, the extinguisher does not fall to the ground from one side of the thickened bottom layer firstly, and an impact block is arranged at the bottom of the thickened bottom layer so that the impact blockcan eject a pressing film open when being impacted, accordingly, the impact block enters a lower storage bin to extrude a main pressing rod, a delay switch is pressed to start a second electromagnetic valve and the first electromagnetic valve to extinguish fire, and the first electromagnetic valve and the second electromagnetic valve can be started through the thermal induction coil to extinguishfire under the condition that manual throwing cannot be conducted due to the large fire behavior.

Description

technical field [0001] The invention relates to the technical field of fire extinguishers, in particular to a throwing safety foam fire extinguisher. Background technique [0002] Foam fire extinguisher, the principle of fire extinguishing is that when extinguishing a fire, it can spray a large amount of carbon dioxide and foam, which can adhere to combustibles, isolate the combustibles from the air, and achieve the purpose of fire extinguishing. Foam fire extinguishers are divided into: portable foam fire extinguishers, carts Type foam fire extinguishers and air type foam fire extinguishers, foam fire extinguishers should be stored in a dry, cool, ventilated and accessible place, not close to high temperature or places that may be exposed to the sun, so as to prevent carbonic acid decomposition and failure, antifreeze measures should be taken in winter to prevent Prevent freezing; and should often wipe off the dust, dredge the nozzle to keep it unobstructed. The existing fo...

[0002] Foam fire extinguisher, the principle of fire extinguishing is that when extinguishing a fire, it can spray a large amount of carbon dioxide and foam, which can adhere to combustibles, isolate the combustibles from the air, and achieve the purpose of fire extinguishing. Foam fire extinguishers are divided into: portable foam fire extinguishers, carts Type foam fire extinguishers and air type foam fire extinguishers, foam fire extinguishers should be stored in a dry, cool, ventilated and accessible place, not close to high temperature or places that may be exposed to the sun, so as to prevent carbonic acid decomposition and failure, antifreeze measures should be taken in winter to prevent Prevent freezing; and should often wipe off the dust, dredge the nozzle to keep it unobstructed. The existing foam fire extinguishers are basically the same as ordinary fire extinguishers, mostly in cans. Residents with firefighting experience say it is inconvenient to use
