DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. 1 to 4, reference numeral 1 denotes a stopper body in which a connection port 2 for a water supply system (or a hot water supply system) such as a water supply pipe or a cold water tank is connected, and a water discharge cylinder 4 having a downward water discharge port 3 is disposed upward. It is composed of a main body portion 1a provided continuously, and a cylindrical portion 1b having a water passage 5 and a valve seat 6 formed on the distal end side.

Reference numeral 7 denotes a spindle (plug) which is slidably held with respect to the cylindrical portion 1b. The spindle 7, a slide valve 8 provided on the distal end side of the spindle 7, and a valve seat of the cylindrical portion 1b. A slide type on-off valve 11 is constituted by a spring 6 for urging the slide valve body 6 and the slide valve body 8 toward the valve seat 6 side.

Reference numeral 12 denotes an operation member mounted on the front end of the spindle 7. The water outlet 3 is located immediately above the operation member 12. The operation member 12 pushes the slide valve body 8 to operate. In addition, 13 is a heat insulating cover, and 14 is a rubber cover for buffering the contact with the glass 15.

In the above configuration, the operating member 12
When a cup or the like is pressed against the container, the slide valve body 8 slides to open the on-off valve 11, and water is poured into the cup pressing the operation member 12, and the cup is discharged from the spout 3 The opening / closing valve 11 is opened by the operation of bringing it down, and the opening / closing valve 11 is closed by the operation of removing the cup.

Reference numeral 15 denotes a flow control mechanism provided with a rectifier 16 provided on the main body 1a. The flow control mechanism 15 includes a holder 17 mounted on the main body 1a,
And a spring pin 19 for holding the rotating member 18 in the holder and restricting the rotation.

Further, the holder 17 has a cylindrical upper portion 20 having a pair of first openings 21 and 21 in a side wall 20a,
A lower portion 23 composed of an annular flange 22 having a diameter larger than that of the upper portion 20 is integrally formed. Also, the upper part 20
Has a groove 24 formed by cutting out a predetermined length in the annular upper end surface M. In this embodiment, the first apertures 21 and
1 are respectively formed at positions facing each other, and grooves 24 are formed.
Are cut out by a length corresponding to the rotation restriction angle of 90 °. A hole P for fixing the holder 17 having a female screw W formed therein is formed at the holder 17 mounting position of the main body portion 1a.
Is formed below the positions of the first openings 21 and 21 of the upper portion 20, and the holder 17 is configured such that the upper portion 20 has the main body portion 1a.
It is fixed so as to protrude inside.

On the other hand, the rotating member 18 has a top 25 which is fitted inside the upper portion 20 of the holder 17, a photographing portion 26 which accommodates the rectifier 16 and abuts on the annular flange 22 and projects downward from the holder 17, A column 27 provided between the top 25 and the photographing unit 26 is integrally formed. And
The water outlet 3 is formed below the rectifier 16 housing position of the photographing unit 26. In addition, a pair of second openings 28, 28 (see FIG. 5B) are formed in the side wall 25a of the top 25 to communicate with the first openings 21 and 21, respectively, and to adjust the flow rate. And a pin hole 29 just above the second openings 28, 28.
Are drilled. Therefore, the spring pin 19 is inserted into the pin hole 29 and the groove 24 so that the spring pin 1
The rotation of the rotating member 18 can be restricted to 90 ° by the contact between the groove 9 and the groove end portions (abutments) 24a, 24a. Note that 30,
31 is an O-ring for sealing, respectively. In addition,
FIG. 5B is a cross-sectional view taken along line BB of FIG.
FIG. 5C is a cross-sectional view taken along the line CC of FIG.

Thus, a flow control mechanism 15 with a rectifier is provided on the main body 1a, and the flow control mechanism 15 is provided with a holder 17 mounted on the main body 1a,
And a spring pin 19 rotatably fitted into the pin hole 2 provided in the top 25 of the rotary member 18 through the groove 24.
The rotation member 18 can be held by the holder 17 by being inserted into the holder 9, and the rotation of the rotation member 18 can be restricted to 90 °.
Therefore, the flow rate can be easily adjusted without a jig by simply taking and turning the photographing section 26 protruding downward from the holder 17, and the flow rate can be visually confirmed.

That is, the user can easily adjust the flow rate of the water poured into the cup 15 by visually adjusting the rotation of the photographing section 26 on the spot, which is very convenient and functional for the user.

However, only the flow control mechanism 15 and the rectifier 1
Just by integrating 6 with water,
There is a risk that the water will be twisted and the rectification state will deteriorate. In other words, the water is scattered or the water is twisted because the flow passage is narrow, the flow velocity increases, and air is trapped at the tip of the water discharge portion. In order to solve these problems, in this embodiment, a pillar 27 is provided between the top 25 and the photographing part 26 of the rotating member 18 rotatably fitted in the holder 17. This makes it possible to form a wide water channel, so that water can be prevented from being scattered, and twisted water as shown in FIGS.
7 (see FIGS. 5A and 5C), it is possible to avoid water twisting.

As described above, the rectifier 16 is attached to the holder 17.
And a simple configuration in which the three-point parts of the rotating member 18 and the spring pin 19 are combined, so that the push can be performed with a small number of parts at a low cost without deteriorating the rectification state and the function of the rectifier and the flow rate adjustment function. A water faucet can be provided.

It is needless to say that the configuration of the present invention in which the rectifier also serves as a flow rate adjusting mechanism can be employed in a lever-operated push-type faucet. Rotating member 1
8 is not limited to 90 °.

[0020]

As described above, according to the present invention, a flow control mechanism with a rectifier is provided in the plug body, and the flow control mechanism is
The holder comprises a holder attached to the stopper body, a rotating member rotatably fitted in the holder, and a spring pin, and the spring pin is provided on the upper end surface of the upper portion of the holder at a length corresponding to the rotation regulating angle. The rotating member is held by the holder by inserting it into the pin hole provided at the top of the rotating member through the groove formed by notching, and the rotation of the rotating member can be regulated. The flow rate can be easily adjusted without any jigs and tools by a simple operation in which the user takes and turns the only part.

Therefore, the user can easily and visually confirm the flow rate of the water poured into the cup by visually adjusting the rotation of the photographing section, which is very convenient and functional for the user.

In addition, according to the present invention, by providing a pillar between the top of the rotating member rotatably fitted in the holder and the photographing portion, a wide flowing water channel can be formed, and water can be prevented from being scattered. The water that has collided with the downstream pillar prevents the water from being twisted, thereby avoiding deterioration of the rectification state.
