Description

[Detailed Description of the Invention] This invention relates to a water spray nozzle used for water spray hoses, etc.

BACKGROUND ART Conventionally, for example, as a water spray nozzle for Jiyoru, there is a structure in which an elliptical Nash plate with a large number of small holes is fixed to the oblique opening surface of a nozzle head.

However, there is a drawback that the small holes of the mesh plate cannot be cleaned of dirt, and as a measure to improve this, a mesh plate holding ring is removably screwed onto the beveled opening edge of the nozzle head, and the holding ring is used to hold the mesh plate. A method of detachably attaching the plate has been considered, but this is impossible because the oblique opening is oval, and a new idea has been desired to solve this problem.

The water spray nozzle of the present invention can solve the conventional problems, and the details thereof will be explained below with reference to the drawings.

As shown in the first and third figures, the nozzle head 1 is shaped like a hollow funnel whose tip is widened into an oval opening 2, and an annular flange 3 is protruded from the end of the opening 2. A male thread 4 is provided on the outer circumferential surface of the holder, and a mesh plate receiving stepped portion 5 is formed on the inner circumferential surface.

The mesh plate 6 is an oblong metal thin plate with many small holes.
Its peripheral portion is fitted into the receiving step portion 5 via a packing ring 7 made of rubber or the like.

As shown in the first and fourth figures, the presser ring 8 that presses down the mesh plate 6 has an oval water sprinkling opening 2' with an inner diameter that is approximately equal to the opening 2 of the nozzle head 1, and is fitted into and removed from the receiving step 5. A ring-shaped flange 10 is protruded from the middle part of the outer peripheral surface of the presser ring main body 9, which is made of an oval short cylinder having an outer diameter of .

The main body 9 of this presser ring 8 is fitted into the receiving step 5 of the nozzle head 1, and the peripheral edge of the bush plate 6 is held between the end of the main body 9 and the receiving step 5. The retaining ring 8 is secured by the cap nut 11 screwed onto the male thread 4 of the flange 3.
A flange 10 of the nozzle head 1 is fastened to a flange 3 of the nozzle head 1.

As shown in the first diagram, the cap nut 11 has an inner flange 13 protruding inward from one end of a nut main body 12 having a female thread on the inner circumferential surface. When screwed on, the inner flange 13 will tighten the flange 10 of the presser ring.

14 is a connecting pipe connected to the rear end of the nozzle head 1.

The function of the water spray nozzle of the present invention is as follows.

As an example, the nozzle A of the present invention is attached to a girder P as shown in Figure 5, with the oval watering opening 2' facing sideways (the first
, the state shown in Figure 2), when watering is performed in this state, the emitted water spreads laterally, thereby avoiding the leaves of the plant and supplying water mainly to the roots.

If the small holes of the mesh plate 6 become clogged with dirt, turn the cap nut 11 to unscrew it from the flange 3, and then use the presser ring 8 to separate the mesh plate 6 from the stepped portion 5. .

The separated mesh plate 6 is assembled to its original state after dust is sufficiently removed.

In the present invention, the shapes of the openings 2 and the water sprinkling openings 2' are not limited to the above-mentioned oval shape, but may be any other elongated shape such as an ellipse or a rectangle.

According to the water spray nozzle of this invention, although it has a rectangular water spray opening, the mesh plate can be freely attached and detached by attaching and detaching the cap nut, which prevents clogging of the small holes of the mesh plate. If dirt accumulates inside the hollow nozzle head, it can be cleaned immediately, which is extremely effective in practice.

In addition, if the present watering nozzle is used with its rectangular watering opening facing sideways, it will be possible to supply water mainly to the roots of the plant, avoiding the leaves of the plant, thereby achieving ideal watering. There are also benefits that can be obtained.
