Abstract

The invention discloses a spraying square gun. The spraying square gun comprises an outer cover and a sleeve cover; a spraying pipe is arranged in the outer cover; a sucking pipe is arranged on the outer cover; the spraying pipe includes a spraying pipe section and a straight pipe section; a liquid outlet one-way valve is arranged in the straight pipe section; a nozzle part and a pressing cylinder are arranged on the outer cover; the outer end of the pressing cylinder is communicated with the external, and the inner end of the pressing cylinder is communicated with the spraying pipe; a piston is arranged in the pressing cylinder; the outer cover is provided with a spanner for pushing the piston; a main spring is arranged in the pressing cylinder; one end of the main spring is contacted with the inner wall of the spraying pipe, and the other end of the main spring is contacted with the piston; the pressing cylinder is provided with an outer intake hole communicated with the internal of the sleeve cover; the outer intake hole is sealed by the piston; and an outer cover is arranged on the nozzle part. The spraying square gun has the beneficial effects of: reasonable and compact whole structure, stable and firm working process, capability of effectively extruding liquid and automatically resetting, difficult liquid leakage among all movable structures, good total sealing performance, capability of effectively relieving the hand pressure of users and scientific pressing angle.

Description

technical field [0001] The invention belongs to the technical field of liquid pressure pumps, in particular to a spray square gun. Background technique [0002] Liquid pressure pumps are widely used in daily life, such as shampoo, perfume, mosquito killer and other bottled liquid products. The spray (square) gun is also a kind of liquid pressure pump. It usually includes a piston rod, a pump body and other structures. The pump body is directly installed on the liquid container. Its main working principle is to use the internal pressure of the piston to reduce the space in the liquid container. , The air pressure increases, thereby pressing out the liquid in the liquid container. However, although the current hydraulic pump structure can realize the extrusion of liquid, it is still lacking in overall sealing performance, prevention of backflow and leakage, and the like. Contents of the invention [0003] The present invention aims to overcome the deficiencies in the prior...
