Description

Technical Field

[0001] The present application relates to the technical field of firefighting, and in particular to a firefighting water gun. Background Art

[0002] As we all know, fire hose is a firefighting tool that extinguishes fire by shooting water. It is one of the necessary firefighting equipment for fire trucks, public places, factories, schools, warehouses, etc. In order to make the hose have a longer range and a larger fire extinguishing radius, the water flow needs to have a higher pressure. With the rapid development of my country's social economy, various types of fire accidents have become more diverse and complex. Therefore, multifunctional fire hose plays an increasingly important role and has been widely used.

[0003] When the existing water gun sprays water, the size of the fire and the water flow will be different. The size of the water flow is closely related to the efficiency of fire extinguishing. Therefore, we propose a fire-fighting water gun with adjustable water flow to solve the above-mentioned problems. Utility Model Content
