Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a water discharge device that can select between concentrated water and sprinkling water.

[Conventional technology and its problems]

When using tap water to water garden trees, etc., or when washing a car, connect a hose to the faucet, guide the water to the designated location with the hose, and press the end of the hose appropriately with your hand. change its shape,
The flow rate of water was changed, but for reasons such as cumbersome, we installed a stop valve inside the end of the hose.
A water discharge device with a switching mechanism between concentrated water and sprinkled water (shower-like water) was used.

However, in the conventional water discharge device, a valve for switching concentrated water and a valve for switching water spraying are separately disposed inside, and therefore, when switching from concentrated water to sprinkling, the valve for concentrated water must be stopped once, When changing from sprinkling to concentrated water by opening the sprinkler valve, it was necessary to stop the sprinkler valve and then open the concentrated water valve, which caused the problem that the operation was troublesome.

The present invention has been developed in view of the above circumstances, and an object of the present invention is to provide a water discharging device that can perform water sprinkling from concentrated water and vice versa with a simple operation.

The water discharge device according to the present invention that meets the above purpose is provided with a water introduction part connected to a hose at the bottom, and a water opening/closing device that opens and closes water from the water introduction part by operating an operating handle. a cylindrical water guide part that is attached to the tip of the grip part and has a water discharge port formed at the tip; The water spout consists of a water discharge part with a concentrated water hole in the center of the interior, and a water switching part disposed inside the water discharge part to switch water to the water spout, and the tip of the cylindrical water guide part has the above-mentioned water discharge part. A seal part that engages with the concentrated water hole of the water discharge part, and a protrusion in the middle part thereof that performs a pressing operation of the water switching part, and the water discharge part is screwed into the cylindrical water guide part. The structure is such that switching between sprinkling water and concentrated water can be performed by .

[Effect]

The grip part is provided with a water introduction part connected to a hose to guide water inside, and furthermore, a water opening/closing part driven by the operating handle is provided inside,
The water introduced by the hose is opened and closed.

A cylindrical water guiding portion is connected to this handle portion to guide water from the handle portion to a water outlet at the tip.

A water discharge part is screwed into this cylindrical water guide part, and a switching part operated by a projection provided on the cylindrical water guide part is provided inside the cylindrical water guide part. By moving the screw in the section, the water from the water outlet can be switched to sprinkling or concentrated water.

An inner hole 16 and a horizontal hole 17 connected thereto are formed inside the grip part 11, and the water introduction part 1
The water from the hole 5 is guided to the tip of the horizontal hole 17.

Inside the horizontal hole 17, there is a spring 1 at the tip.
8, a valve body 21 is attached which is always pressed against a ring-shaped rubber gasket 20 provided at the tip opening 19 of the horizontal hole 17, and an O-ring 21a as a sealing material is attached to the rear of the valve body 21, and a latch An operating rod 23 with a section 22 is provided. An operating handle 24 is attached to the hook 22, and by pressing the operating handle 24, the valve body 21 opens and closes the tip opening 19 of the horizontal hole 17.

A male thread 25 is formed around the tip opening 19 of the horizontal hole 17, and the cylindrical water guide portion 1 is attached to the male thread 25.
2 are screwed together with the rubber gasket 20 sandwiched therebetween.

This cylindrical water guiding part 12 has a water hole 26 formed therein, a water discharge port 27 formed at the tip thereof, and a water outlet 27 formed at the end thereof, which fits closely into the concentrated water hole 28 of the water discharge part 13. An O-ring groove 30 into which an O-ring 29 is mounted is formed.

A male thread 31 is formed on the outer side of the intermediate portion of the cylindrical water guiding portion 12, and an O-ring 3 is formed at the end of the male thread 31.
A fold 33 is formed to reduce the weight of the O-ring groove 32 in which the O-ring groove 2a is attached, and the water discharge part 13 is threadedly engaged with the water discharge part 13 so that the entire water discharge part 13 moves laterally.

On the other hand, a ring-shaped protrusion 34 is formed behind the water discharge port 27 of the cylindrical water guide section 12, and is adapted to press the switching section 14 disposed inside the water discharge section 13.

The water discharging part 13 has a female thread 35 formed in the middle part thereof to be screwed into the male thread 31, a water sprinkling port 36 at the tip thereof, and the above-mentioned concentrated water hole 2 at the center of the tip.
8 is formed. The water sprinkling port 36 is composed of a metal plate 37 with an inner hole formed in the center and a plurality of small holes formed at predetermined intervals on the surface of the metal plate 37. Moreover, the inner hole and the outer periphery of the metal plate 37 are formed in a ring shape. Water discharge part 1 is installed by mounting plates 39 and 40 made of rubber plates.
It is attached to the case body of 3.

The above-mentioned switching section 14 is provided inside the water discharging section 13, and the switching section 14 consists of radially provided protrusions 41 that engage with the protrusions 34 formed on the cylindrical water guide section 12, and An O-ring groove 42 that constitutes a seal that prevents water from reaching the water sprinkling port 36 when water is used, and the O-ring groove 42
A ring-shaped protrusion 45 provided at the rear of the switching portion 14 in a natural state.
