Abstract

The invention relates to a device capable of adjusting the spraying area, in particular to a water gun nozzle capable of changing the spraying area. The head of the water gun uses a fixed diverter, and the diverter is connected to the outlet pipe through a hose. There is a connecting rod on the head of the water gun. When the handle is pushed, the ring slider of the connecting rod moves to realize the diversion of the outlet pipe Opening and shrinking can be used to change the spraying state, so that the water flow is sprayed in an umbrella-shaped state, which can significantly increase the effective area of ​​spraying water, so as to facilitate the cooling of water and absorb heat and smoke. In this way, large-area spraying can be realized, which can be widely used Firefighting, daily life and other industries, and the operation is convenient and simple, and it is easy to promote and use.

Description

technical field [0001] The invention relates to a device capable of adjusting the spraying area, in particular to a water gun nozzle capable of changing the spraying area. Background technique [0002] At present, most of the sprinkler nozzles used in the market are direct spraying type, which cannot shrink and spray in a large area. If there is a danger, it can only spray in one direction, and it cannot eliminate the danger in time, which is very inconvenient. [0003] The invention relates to a water gun head capable of changing the spraying area. The water gun head uses a fixed diverter, and the diverter is connected to the branch water pipe through a hose. The water gun head is provided with a connecting rod. When the handle is pushed When the circular slider of the connecting rod moves, so as to realize the divergence and contraction of the branch water pipe, it can be used to change the spray state, so that the water flow is sprayed in an umbrella-shaped state, and the...
