The present invention relates to a spray nozzle used for attaching to a sink faucet or a bathroom shower.

In the conventional water spray nozzle, as shown in FIG. 1, the lever L is eccentrically installed on the inner surface of the water spray plate P, and a disc-shaped opening and closing plate L 'is formed at the inner end of the lever L. It is configured to open and close the discharge hole (H) drilled in the center of the sprinkling plate (P).

The water spray nozzle of the above-described structure, as the user operates the lever L, the opening / closing end L 'blocks or opens the center discharge tube H so that water is directly discharged through the discharge hole H, or Alternatively, since the water is bypassed by the real plate P, the airtightness is hardly maintained between the opening and closing plate L 'and the discharge hole H.

Due to this, even in the use of watering, water flows down through the gap between the opening and closing plate L 'and the discharge hole H, thereby reducing the watering effect. In particular, the lever L is easy to cause interference with external objects when used. There is a problem that it is not suitable, and there is a drawback that the lever (L) is easily broken.

In addition, when converting the sprinkling water to the direct water, holding the sprinkling cover (C), and the lever (L) must be rotated, so there is inconvenience in using both hands.

The object of the present invention is to provide a watering nozzle in which the lever is not exposed to the outside to solve the above-mentioned conventional problems, which will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2 and FIG. 3, a suspension plate 4 is press-fitted to the inner end 3 of the stepped support part 2 in which the ball joint 1 is integrally formed upward, and the ball joint 1 is provided. Is removably connected to the coupling 6 by means of a screw cap 5.

The sprinkling plate 8 in which several sprinkling holes B are perforated is integrated with the spraying cap insertion hole 10 in which a plurality of pinching grooves 9 are formed, and is screwed onto the sprinkling cap 7 lower shaft.

In the lower side of the suspension plate 4, the valve plate 11, the conventional water barrier tube insertion hole 10 is sequentially positioned to be inserted into and fixed to the inside of the support 2 on the staircase, thereby forming the space T.

On one side of the valve plate 11, the hole 13 communicating with the discharge hole 12 held by the suspended plate 4 is drilled, and the upper part protrudes to insert the sealing ring S1.

In addition, a plurality of local holes 15 are formed at the outer circumference of the valve plate 11 to be inserted into the pinching grooves 9, and a plurality of protrusions 14 to prevent sagging of the suspension plate 4 protrude. do.

On the other hand, the sprinkling passage 16 is formed on the lower inner peripheral surface of the support portion 2 integral with the ball joint 1.

Unexplained symbol S2 is a sealing ring for preventing the water and 17 is a water pipe.

In the present invention configured as described above, the sprinkling cap 7 is configured to be rotatable about the support 2, and the suspension plate 4 has the ball joint 1 of the screw cap 5 of the coupling 6. By being tightened strongly, the watering plate 8 is tightened at the lower portion of the watering cap 7, the suspension plate 4 and the sealing ring (S1) is in close contact can be prevented from leaking.

That is, as a sprinkling conversion action, when the sprinkling cap 7 is rotated first, the sprinkling plate 8 is rotated together because it is screwed together.

At this time, because the gripping groove 15 of the valve plate 11 is inserted into the gripping groove 9 formed in the water-proof prevention insertion slot 10, the valve plate 11 is also rotated together.

However, since the suspension plate 4 is press-fitted into the inner end 3 of the support part 2, the suspension plate 4 always remains fixed.

As such, the rotation of the sprinkling cap 7 brings about the rotation of the valve plate 11, so that the discharge hole 12 of the suspension plate 4 is formed between the hole 13 and the protrusion 14 of the valve plate 11. Selective communication between them.

For example, when the sprinkling cap 7 is rotated so that the discharge hole 12 communicates with the hole 13, the water flowing through the coupling 6 is space part T → discharge hole 12 → hole. (12) → discharged directly through the path of the water barrier tube 17 to form a direct water, and when the discharge hole 12 is located between the projections 14, the hole 13 is closed and through the coupling 6 If the discharged water 12 is located between the protrusions 14 and the holes 13 are closed, the water flowing through the coupling 6 is discharged from the hole 12 → the periphery of the protrusions 14. → watering path (16) → watering (B) is the path to watering.

When water is discharged to the water protection pipe 17 during the above process, the peripheral air is sucked into the outer circumferential axis of the discharge pipe 17 to form an air curtain, so that the water is not scattered.

4 shows a modification of the valve plate 11 in the above embodiment.

The valve plate 11 of the above-described embodiment forms a separate passage from the direct passage hole 13, and the valve plate 11 is a watering passage hole located within the same circumference with the direct passage hole 13 ( 111).

The sprinkling passage hole 111 forms a direct passage as a hole 13, but is in communication with the extension passage 112, which is improved in the outer circumferential radial direction of the valve plate 110 in this embodiment.

Since all components except for the valve plate 110 have the same structure as the components described above, the conversion of the direct water is the same, and the conversion of the sprinkling water has the following path.

When the sprinkling cap (7) is rotated to match the sprinkling position, the water flowing through the coupling (6) is space part (T) → discharge hole (! 2) → sprinkling passage hole (111) → extension passage (112). → watering passage (16) → watering (B) is the path to the watering.

According to the present invention as described above, since the discharge mode of the water is determined by rotating the sprinkling cap 7, the lever is not required as in the related art, and thus, a failure does not occur and the shower shower nozzle can be used as a bath nozzle. Particularly, when water is sprayed, water is leaked to the water splash prevention pipe 17 because the discharge hole 12 of the suspension plate 4 and the hole 13 of the valve plate 11 are completely blocked. The lack of water will improve the watering effect.
