Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shower nozzle that is attached to the tip of a hose connected to a water faucet to spray water.

Shower nozzles are already known in which a porous screen is attached to the tip of the valve part that adjusts the water flow, and water is sprayed from the screen by adjusting the amount of water by opening and closing the valve part. , watering from the screen becomes uneven due to changes in water volume.

In particular, when the valve part is throttled to reduce the amount of water, the water is strong only in the center of the screen, which has the disadvantage that uniform watering cannot be achieved.

This invention was made in order to eliminate the above-mentioned drawbacks, and it is possible to provide a shower nozzle that can obtain uniform water spray from a screen even when the amount of water changes, especially when the amount of water is small. It is a purpose.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a first example of the present invention, in which a hose connection portion 2 is provided at the base end of a nozzle body 1 whose tip is closed, and a through hole 3 is formed in the peripheral wall of the tip. There is.

The hose connection part 2 is formed by a retaining protrusion 4 formed on the outer peripheral surface of the narrowed end of the nozzle body 1, and a hose tightening tube 5 externally fitted and screwed to the tip of the protrusion 4. It is formed.

An inner cylinder 6 is fitted onto the outside of the nozzle body 1 at a midway point from the tip, and an outer cylinder 7 is fitted onto the outside of the inner cylinder 6.

The inner cylinder 6 has a female thread 8 formed on the inner circumferential surface on the base end side and is screwed into a male thread 9 of the nozzle body 1, so that the inner cylinder 6 can be moved in the axial direction by rotating the nozzle body 1.

A valve portion 10 for controlling the amount of water flowing out from the tip opening of the inner tube 6 is provided on the inclined surface provided at the tip of the nozzle body 1 and at the inner end of the tip cylindrical portion of the inner tube 6. A nozzle portion 12 is formed by the protruding shaft 11 on the distal side of the tube 10 and the cylindrical portion.

The valve portion 10 is opened and closed by movement of the inner cylinder 6 by rotation, and the nozzle portion 12 sprays or sprinkles water depending on the amount of water.

A female thread 13 formed on the inner circumferential surface of the proximal end of the outer cylinder 7 is screwed into a male thread 14 of the inner cylinder 6, and the outer cylinder 7 is moved in the axial direction by a rotation operation with respect to the inner cylinder 6.

The amount of water flowing between the inner cylinder 6 and the outer cylinder 7 from the through hole 15 provided in the peripheral wall of the inner cylinder 6 flows into the opening at the tip of the outer cylinder 7 and the inclined surface at the front end of the inner cylinder 6. A valve portion 16 is formed to control the.

This valve portion 16 is opened and closed by movement of the outer cylinder 7 by rotational operation.

An annular wall 17 is provided on the outer circumferential surface of the outer cylinder 7 in the middle thereof, and the annular wall 17 extends outward from the distal end side. It is being

This screen 19 is porous with a large number of small holes 20, and its inner peripheral edge is fitted onto the cylindrical end of the inner cylinder 6 so as to be able to freely slide in the axial direction. covers the front of the

A flange 21 is provided on the outer periphery of the tip of the inner cylinder 6 at a position closer to the tip than the valve portion 16 to diffuse water flowing out from the valve portion 16 throughout the screen 19.

In the case of the first embodiment, the above-mentioned collar 21 is formed by fitting a washer-like disc into the cylindrical end of the inner cylinder 6,
Moreover, in the case of the second embodiment shown in FIG. 2, it is provided integrally with the cylindrical portion of the inner cylinder 6.

The shower nozzle of this invention has the above five configurations,
A connecting part 2 provided on a nozzle body 1 is connected to a hose connected to a water faucet.

To perform shower watering, press the nozzle body 1 as shown.
With the valve part 10 formed at the tip of the inner cylinder 6 closed, the outer cylinder 7 is rotated to open the valve part 16 formed by the outer cylinder 1 and the inner cylinder 6.

The water that has flowed into the nozzle body 1 flows out toward the screen 19 through the through holes 3 and 15.

At this time, the water flowing out from the valve part 16 toward the screen 19 collides with the collar 21 immediately after passing through the valve part 16.
This collision causes the water to diffuse, and therefore, regardless of the amount of water, it is uniformly dispersed over the entire screen 19, resulting in a uniform water spraying state from the entire surface of the screen 19.

When discharging a large amount of water or spraying straight water, the inner tube 6 may be rotated to open the valve section 10, and the outer tube 7 may conversely throttle the valve section 16.

As described above, according to the present invention, a valve part for controlling the amount of water flowing out to the screen in front is formed at the tips of the inner cylinder and the outer cylinder, and a collar is provided on the outflow side of the valve part on the outer periphery of the inner cylinder. Therefore, the water passing through the valve portion toward the screen is diffused by the collar, and there is an effect that uniform watering can be obtained from the entire surface of the screen regardless of the amount of water.
