[0001] The invention relates to fire-fighting equipment, in particular to an anti-backfire drilling type fire-fighting water gun. Background technique
[0002] There is a very dangerous phenomenon at the fire scene. When a fire occurs in a confined space, because the space is relatively sealed and oxygen is insufficient, incomplete combustion will generally occur and a large amount of toxic, flammable and explosive gases such as carbon monoxide will be produced. However, due to insufficient oxygen, so These toxic, inflammable and explosive gases cannot be burned and consumed, and gradually accumulate in the confined space. At this time, if the doors and windows of the confined space are opened and a large amount of fresh air flows in, the large amount of toxic, inflammable and explosive gases in the confined space will instantly reach the deflagration point, causing Deflagration or even explosion, this is the backfire phenomenon, and it is very dangerous for ...
