Watering is done in a pattern.

[0004]

In the above-mentioned conventional multi-shower nozzle, the setting position of each sprinkling pattern sometimes shifts during sprinkling, and in such a case, the sprinkling amount decreases or other adjoining There was a case where it was confused with the watering pattern of the set position.

Further, in order to always obtain a good water spraying condition, it is necessary to easily clean the water spraying plate, but in the conventional multi-shower nozzle, the water spraying plate is integrated with the rotation guide, so that It wasn't easy to clean.

The present invention has been made in view of such circumstances.
An object of the present invention is to provide a sprinkling nozzle in which a sprinkling pattern can be easily and reliably set and a sprinkling plate can be easily cleaned.

[0007]

The present invention comprises means for solving the above-mentioned problems as follows. That is, a fixed guide fitted and fixed to the nozzle head through an O ring, a fixed plate having a water passage hole and inserted into the fixed guide through an O ring, and a water passage hole of the fixed plate, respectively. A diffusion plate that has a plurality of corresponding diffusion holes and that is fitted into a screw ring that is screwed into the fixed guide and that corresponds to the fixed plate through a sheet packing and that is rotatable about its axis;
A sprinkler plate having a plurality of sprinkler holes corresponding to the respective diffusion holes of the diffuser plate, which is fitted and fixed to the front surface of the diffuser plate, and attached to and detached from the sprinkler plate by a holding screw ring which is screwed and fitted to the sprinkler plate. A rotation guide that is freely fitted and fixed, and a ratchet ring is attached to the rear peripheral edge of the rotation guide, and a concave portion that releasably engages with the convex portion of the ratchet ring is formed on the inner circumference of the nozzle head. The rotation of the water spray holes of the water spray plate is set so that the rotation guides can be freely set through the diffusion holes of the diffusion plate to the positions corresponding to the water holes of the fixed plate. The guide
The nozzle head is rotatably and detachably fitted to the nozzle head via the ratchet ring.

[0008]

By rotating the rotation guide, the water spray holes of the water spray plate are made to correspond to the water flow holes of the fixed plate through the diffusion holes of the diffusion plate, and the projections of the ratchet ring engage the recesses of the nozzle head. The rotation guide is set without displacement with respect to the nozzle head.

The rotation guide can be separated from the water spray plate by removing the holding screw ring, and the water spray plate can be easily cleaned.
