CN2277821Y - Nozzle with spiral rifling - Google Patents

Abstract

The utility model relates to a rifling spiral spray head. The rifling spiral spray head is composed of two parts of a spray nozzle 1 and a rifling spiral body 2. The spray nozzle 1 and the rifling spiral body 2 are in sliding fit. When the rifling spiral spray head is used, the spray nozzle 1 and the rifling spiral body 2 are relatively static due to the action of static friction. The spray nozzle 1 is composed of a cavity body 8, a cone 6, and a spray opening 7. The rifling spiral body 2 is composed of a cone 3 and a cylindrical body 5. A plurality of sawtooth-shaped rifling grooves 4 are arranged on the cylindrical body 5. After liquid with definite pressure enters the cavity body 8, the flow of the liquid is divided by the cone 3, the liquid forwards moves along a sawtooth-shaped rifling 4. Rotary liquid is rotated by the spray opening 7 along the inner surface of the cone 6 to be accelerated and sprayed out, and the rotary liquid is formed into a fog shape due to the action of centrifugal force.

Description

Accompanying drawing rifling spiral sprays head

The utility model is a kind of fog-spray nozzle, and particularly a kind of have a rifling structure spiral sprays head.

Sprayer is widely used in industries such as environmental protection, agricultural, forestry, breed, health building, but existing fog-spray nozzle complex structure easily stops up, so existing fog-spray nozzle need improve.

It is simple that the purpose of this utility model provides a kind of manufacturing process, no quick-wear part, not susceptible to plugging novel atomizing head

The utility model is that following mode is finished;

Inner chamber at fog-spray nozzle is shaped on many as the zigzag groove of (or claiming rifling) of the rifling in the bore, but adopt nozzle in order to simplify technology the utility model, rifling conveyor screw two body structures, after the liquid with certain pressure enters nozzle chambers, because of the spirochetal end of rifling is that a cone makes separating liquid and travels forward along many zigzag grooves, the liquid of rotation, sprays forward because of action of centrifugal force nebulizes liquid through spout rotation ejection along interior poppet surface

The utility model has following good effect:

1. simple in structure, good manufacturability is convenient to processing.

2. be difficult for stopping up, be convenient to safeguard.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Accompanying drawing is a principle front view of the present utility model.

The utility model is made up of nozzle 1 rifling conveyor screw 2 two parts, 1,2 liang of bodies are for being slidingly matched, effect two bodies because of static friction during use are static relatively, nozzle 1 is made up of cavity 8 cones 6 spouts 7, rifling conveyor screw 2 is made up of cone 3 cylinders 5, is shaped on many zigzag rifling grooves 4 on the centrum 5.Liquid with certain pressure enters cavity 8 and travels forward along zigzag rifling 4 after the shunting of cone 3, and the liquid of rotation quickens ejection along the inner surface of cone 6 through spout 7 rotations, because of action of centrifugal force, liquid is nebulized.

Claims (1)

1. a new-type rifling spiral sprays head is by nozzle 1,2 two ones of rifling conveyor screws form and it is characterized in that:

A. nozzle 1 is made up of cavity 8 cones 6 spouts 7 three parts;

B. rifling conveyor screw 2 is made up of cone 3 cylinders 5;

C. be shaped on many zigzag rifling grooves 4 on the cylinder 5.
