Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a water spray nozzle.

(Conventional technology and its problems) Conventional water spray nozzles have the functions of direct water spray (like water sprayed in a straight line with a water gun) and atomized water spray, and these can be used for various purposes. It was used differently depending on the situation.

However, since the above-mentioned water spray nozzle does not have the function of rectifying water discharge (water flowing out from the hose connected to the faucet), each time when rectifying water discharge, the water hose must be connected to the water spray nozzle. It was removed and watered.

Therefore, there was a problem in that switching to rectifying water spraying took time and effort, making it impossible to perform a simple and quick watering operation.

(Technical problem to be solved by the invention) The technical problem of the present invention, which attempts to solve the above problems, is to provide a watering nozzle with a watering function of rectifying water in addition to direct water spraying and atomized water spraying. That's true.

(Technical Means for Achieving the Technical Problem) The technical means of the present invention for achieving the above-mentioned technical problem is to provide a water passage internally, and a water passage communicating with the water passage on the peripheral wall of the distal end. A water spout is bored, and a slide valve is installed on the outside so that it can elastically slide within a predetermined range along the axial direction, and a water spout into which the needle fits into the nozzle body is provided with a needle protruding from the tip. In a water sprinkling nozzle in which a rotary cap is rotatably screwed together and the amount of water sprayed is adjusted by rotating the rotary cap, injection ports are spaced appropriately in the circumferential direction around the water sprinkling port in the rotary cap. The nozzle is characterized in that a large number of holes are provided at the same time, and the rear side of the nozzle can be moved into and out of contact with the tip of a slide valve provided on the nozzle body, and a rectifying ring is provided in front of the nozzle.

(Effects of the invention) The present invention has the following effects by having the above configuration.

A spray hole is drilled in the rotating cap of the water spray nozzle, and a rectifying ring is provided in front of the spray hole, so that by one-touch operation of rotating the rotary cap, the water spraying state can be changed to direct water spray, atomized water spray, or rectified water spray. Each can be used for discharging water.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a nozzle body, which has a water passageway 4 therein, and a water passageway 5 that communicates with the water passageway 4 is bored in the peripheral wall of the tip end. Further, a needle 6 is bored in the tip, and a slide valve 7 that can be slid back and forth is fitted and attached to the outside.

The slide valve 7 is formed by fitting a rubber gasket 9 to the tip of a cylindrical slide ring 8, and an engagement groove 10a is recessed in an engagement piece 10 protruding from the rear end of the slide ring 8 to protrude into the nozzle body 1. The provided engagement protrusion 11a is fitted and engaged, and the engagement protrusion comes into contact with the rear end of the engagement groove 10a, so that the slide valve 7 is slid rearward integrally with the nozzle body 1. ing.

Further, the slide valve 7 is always urged forward by a spring 12 that is elastically loaded between a stepped portion formed at the rear end and a flange piece 11 of the nozzle body 1, and can freely move toward and away from an injection port 13, which will be described later. The injection port 1
3 opens and closes.

2 is a rotating cap formed in a cylindrical shape;
By being rotatably fitted to the outside of the nozzle body 1, the needle 6 protruding from the nozzle body 1 is slidably inserted into the water spout 14, and
A through hole penetrating rearward is formed in the rear peripheral wall, and a slide ball 15 is fitted into the rear peripheral wall, and the slide ball 15 is fitted into a spiral groove 16 carved in the rear outer peripheral surface of the nozzle body 1. There is.

In addition, a large number of injection ports 13 (12 in the drawing) are bored at appropriate intervals in the circumferential direction around the water sprinkling port 14 bored in the central part of the front end side of the rotary cap 2. A rectifying ring 17 is fitted and fixed on the front side of the rectifying ring 17.

The rectifying ring 17 is composed of an annular body 17a and a support leg 17b with an appropriate distance between them, and the support leg 17b is fitted into an insertion hole 14a drilled around the water spout 14 and attached thereto.

Further, a refraction surface 18 is formed on the inner surface of the ring body 17a and is inclined at 45 degrees from the outer circumference toward the inner circumference. The direction of the water is changed towards the target, blocking the water discharge from the water sprinkling port 14 and weakening the force, resulting in a rectified water discharge.

Reference numeral 3 denotes a handle ring, which is fitted on the outside of the rear part of the rotary cap 2 and is engaged so as to integrally rotate the nozzle body 1 through concave-convex engagement, and a fixing nut that is screwed onto the nozzle body 1. It is fixed and held at 19.

Further, a hose nut 20 is screwed onto the fixing nut 19, and a hose 20a attached to the end of the nozzle body 1 is tightened and fixed.

Next, how to use the watering nozzle will be explained.

First, by holding the grip ring 3 with one hand and rotating the rotary cap 2 with the other hand, the rotary cap 2 rotates forward along the spiral groove 16 engaged with the slide ball 15. to open the water spout 14 that was blocked by the base end of the needle 6.

Then, the water supplied from the water sprinkling port 14 through the water inlet 5 is sprayed directly (FIG. 2).

Next, by further rotating the rotary cap 2, the rotary cap 2 slides forward while rotating along the spiral groove 16, and the tip head 6a of the needle 6 is inserted into the water spout 14.

The water sprinkling port 14 is narrowed by the tip head 6a, and the water supplied from the water port 5 is sprayed in an atomized form (FIG. 3).

Further, when the rotary cap 2 is rotated, the rotary cap 2 rotates along the spiral groove 16 and slides further forward, so that the tip head 6a of the needle 6 is located at the rear end side of the water spout 14.

Then, the water spout 14 is widened and the slide valve 7 is opened.
moves away from the injection port 13 to open the injection port 12.

The water discharged directly from the injection port 13 hits the refracting surface 18 of the rectifier ring 17 and
7 is refracted at right angles to the center.

Then, when the water directly discharged from the water sprinkling port 14 hits the refracted water concentrated in the center, the two are mixed and the water is discharged in a rectified manner (FIG. 4).
