Abstract

The invention relates to the technical field of sprayer structures, aims to solve the problem that an existing sprayer is inconvenient to operate, and is impacted by a water hammer when opened and closed and is damaged possibly, and provides a sprayer. The sprayer comprises a shell, a sliding piece, a blocking piece, an elastic piece and a trigger. The sliding piece is in sealing fit to the inside of the shell slidably and is provided with a second channel. The blocking piece is fixedly arranged in the shell; a flow opening is formed between the blocking piece and the inner surface of the shell; the elastic piece applies an elastic force pointing to the blocking piece to the sliding piece; the trigger is in transmission connection with the sliding piece and has a first position and a second position; the sliding piece is propped against the blocking piece in a sealed manner when in a first state and is away from the blocking piece when in a second state; and the trigger can drive the sliding piece to compress the elastic piece and the first state of the sliding piece is changed into the second state. The sprayer has the beneficial effects that fire extinguishing substances can be stopped quickly, and the sprayer is convenient to operate, cannot be hammered by the water hammer when opened and closed, and is used safely. The invention further provides a fire-fighting lance.

Description

technical field [0001] The invention relates to the technical field of sprinkler structures, in particular to a sprinkler; the invention also relates to a fire-fighting water gun. Background technique [0002] A fire hose is a device for spraying fire-extinguishing substances for fire-fighting, which is usually composed of pipes connected to nozzles for transporting fire-extinguishing substances. [0003] The fire-fighting water gun in the prior art needs to turn on and off the switch ball valve to realize the on-off of the fire-extinguishing material, which takes a certain amount of time, and the user needs to hold the water gun body with one hand and operate the switch ball valve with the other hand when using it, which is inconvenient to operate; and When shutting off or opening, due to the action of water hammer, the operator will be subject to a recoil force, which may bring certain injuries to the operator or even more serious use accidents. These problems make the ex...
