Description

[Detailed description of the invention] <Industrial application field> This invention relates to a faucet rectifier that is attached to a faucet and rectifies the water coming out of the faucet in a shower-like manner, or rectifies the water so that it does not become turbulent.

<Prior art> The present applicant has published Utility Model Application No. 62-16170 and Utility Model Application No. 62-16170
According to each publication of No. 75820, a hollow rectifier having an attachment port for a faucet and for rectifying the water coming out of the faucet and flowing down is molded from a transparent material, and the hollow part of the rectifier is rotated by the water flow coming out of the faucet. He proposed a rectifier with a built-in water wheel and moving balls.

<Problem to be solved by the invention> The above-mentioned known rectifier is visually interesting because when water is dispensed from the faucet, the rotating water wheel and moving spheres can be seen through the rectifier, and the sound could not occur.

<Means for solving the problem> Therefore, the present invention was developed to address the problem of a rectifier that generates a noise when attached to a faucet and when water is dispensed. A hollow rectifier that rectifies and flows water; a water wheel that is pivotally mounted in the hollow part of the regulator and rotated by the water flow coming out of the faucet; and a cylinder chamber provided separately outside the regulator. and a driving member including a piston that is driven by the water wheel and reciprocates in the cylinder chamber, sucks and exhausts air into the cylinder chamber, and causes the whistle body to generate a sound. The flute body is characterized by a rotatable cover with a notch that makes and stops the sound.

<Example> In the illustrated example, 1 is a hollow rectifier; 2 is a hollow rectifier;
3 is a holding part for the faucet, 3 is a water wheel, 4 is a whistle body, 5 is a driving member, and 6 is a rectifying chamber 1' for the rectifying fluid.
This figure shows a hollow shell with an open bottom and made of plastic that integrally constitutes the cylinder chamber 4' of the flute body 4. The hollow shell 6 has a cross-sectional shape of a dome or a figure eight, and a partition wall 7 separates a rectifying chamber 1' having a large cross-sectional area and a cylinder chamber 4' having a smaller cross-sectional area.

Briefly, the water turbine 3 has a crank 9 at one end 8a of the shaft 8, and the crank 9 projects into the cylinder chamber 4' and is laterally supported within the rectifying chamber 1', so that the water coming out of the faucet is Can be rotated in one direction.
Further, the driving member 5 is a piston that can slide vertically within the cylinder chamber 4', and is connected to the crank 9 by a connecting rod 10, and a slit 11 is formed in the upper wall of the cylinder chamber 4'. Therefore, when the water wheel 3 is rotated in one direction by the water coming out of the faucet, the driving member 5, which is a piston, moves up and down in the cylinder chamber 4', sucking air into the cylinder chamber through the slit 11, and exhausting the sucked air. , the air generates a noise. Then, the water that rotates the water wheel is rectified and flows down from the lower surface of the rectification chamber.

The holding part 2 for the faucet is the same as the previous proposal mentioned above, and the diameter is narrowed from the inner periphery of the upper end and folded back.
It consists of a rubber cylindrical member equipped with a grip tube 2' for gripping the faucet from around it, and a mounting tube 12 having an annular groove on the outer periphery hangs down from the lower end. This holding part 2
The mounting tube 12 is elastically deformed and passed from above into a concentric circular opening formed in the upper wall of the rectification chamber 1' of the hollow shell, and the annular groove 12' is fitted into the peripheral edge of the circular opening. and install it on the top wall.

A rectifying chamber is provided for fixing the holding part 2, for supplying water from the faucet to the water wheel 3 and rotating the water wheel in one direction, and for bearing the other end 8b of the shaft 8 of the water wheel. 1' has ring 1 from the bottom.
3 and fixed to the inner periphery of the upper end of the chamber 1' by high frequency adhesive or the like. This ring 13 has an annular recess 13' on the upper surface, and the mounting tube 12 of the holding part 2 is fitted into this annular recess to prevent the holding part 2 from coming off upward from the circular opening in the upper wall of the rectification chamber. . Also, ring 1
3 has a water supply port 14 for supplying water to the water wheel 3 at an eccentric position on the bottom of the interior surrounded by the annular recess 13', and a bearing piece 15 projects downward from the lower surface. When bonding the ring 13 to the inner periphery of the upper end of the rectifying chamber, the bearing piece 15 is opposed to the partition wall 7 of the hollow shell. As a result, the water supply port 14 is placed in a position that allows the water coming out of the faucet to rotate the water wheel 3 in one direction (see FIG. 2).

Reference numeral 16 denotes a Daruma-shaped or figure 8-shaped plate that closes the lower surface of the rectifying chamber 1' and the cylinder chamber 4', and in this embodiment, a small-diameter water spray hole 17 is provided in the portion 16a that closes the rectifying chamber 1'.
In addition to a large number of openings, a bearing piece 18 that pivotally supports the other end portion 8b of the shaft of the water turbine stands up in cooperation with the bearing piece 15 of the ring 13 described above. Further, there is a ventilation hole 19 in the part 16b that closes the cylinder chamber 4', and a bearing piece 20 for pivotally supporting one end part 8a of the shaft 8 of the water turbine connected to the crank 9 is provided from the boundary between the two parts 16a and 16. stand up Bearing pieces 18 and 20 are of the same shape. The bearing piece 2 is attached to the partition wall 7 of the hollow shell.
A notch 21 of the same shape into which 0 is fitted is provided to open downward.

That is, when fixing the plate 16 to the lower surface of the hollow shell 6 by adhesive or the like, one end 8a of the shaft of the water turbine is placed between the upper surface of the notch 21 of the partition wall 7 that abuts each other, and the upper surface of the bearing piece 20 fitted therein. The other end portion 8b is rotatably supported between the lower surface of the downward bearing piece 15 of the ring 13 that abuts each other and the upper surface of the bearing piece 18. is located within the cylinder chamber 4'. Note that one or both of the upper surface of the notch 21, the upper surface of the bearing piece 20, the lower surface of the bearing piece 15, and the upper surface of the bearing piece 18 surrounds one end 8a of the circular cross section of the shaft 8 and the other end 8b. A circular recess is formed.

A flute pipe 22 is mounted on the upper wall of the hollow shell cylinder chamber 4'.
Fix with adhesive, etc. This flute tube 22 has a closed upper surface and an open lower surface, and has a notched oblique side 24 on one side that faces diagonally inward and downward, keeping a small gap 23 between it and the lower surface. 11
They are almost aligned. As a result, the driving member (piston) 5 moves up and down in the cylinder chamber 4' due to the rotation of the water wheel 3, and when moving downward, it enters the cylinder chamber through the gap 23 of the whistle tube and the slit 11 in the upper wall of the cylinder chamber 4'. When the sucked air then moves upward and is exhausted from the slit 11 and the gap 23, a noise is generated. The interval between sounds is determined by the rotational speed of the water wheel, so the more water comes out of the faucet, the shorter the interval becomes.

In this embodiment, a cover 25 having a notch on one side is rotatably fitted, and when generating a sound, the notch 26 is aligned with the gap 23 of the flute tube so as not to obstruct air circulation. Also, if you do not want to generate noise, turn the cover 25 to close the gap 23.
Close. The cover 25 may be designed to have a decorative effect, such as in the shape of the head of a doll such as an animal, as shown in the figure.

Also, the shaft 8 of the water wheel having the crank 9 is molded out of plastic separately from the water wheel, and the square shaft portion of the shaft 8 is assembled by passing it through the square hole in the center of the water wheel.
These may be integrally molded from plastic.

Furthermore, a large number of water sprinkling holes 17 are provided in the portion 16a of the plate 16.
A hole is opened to allow water to flow down like a shower, but filtration can also be carried out by leaving this part wide open and blocking it with a porous plate or sheet.

Further, the holding portion 2 can be attached to both a large diameter faucet and a narrow faucet using the grip tube 2'. In this case, when attached to a narrow faucet, the lower end of the faucet will come into contact with the bottom at a position away from the water supply port 14 of the ring 13,
There is a risk of obstructing the flow of water. To prevent this, the bottom of the ring 13 is preferably provided with a plurality of parallel ridges 27 which separate the lower end of the faucet above the bottom.

Note that 28 indicates a driving pin for pivotally mounting the piston 5 to the upper end of the connecting rod 10.

In this way, it is possible to provide a rectifier that generates noise with the water rectified from the faucet. By molding the hollow shell from transparent plastic, the mechanism that generates the noise can be seen through, making the rectifier visually pleasing. Furthermore, by providing a cover 25 with a notch, it is possible to make a sound or stop the vehicle.

In the illustrated embodiment, the sound is generated intermittently when the piston moves upward, but the sound may be generated intermittently when the piston moves downward. Furthermore, the sound may be generated continuously when the piston moves up and down. In this case, the sound stops when the piston reaches the top dead center and the bottom dead center. The time interval determines the rotational speed of the waterwheel, and thus the amount of water that comes out of the faucet.

<Effects of the invention> With this invention, the water flow of the faucet generates a sound, creating a sense of enjoyment. In addition, since you can tell whether water is coming out of the faucet without checking with your eyes, you can prevent forgetting to turn off the water, and you can also know the amount of water coming out of the faucet based on the interval between beeps. Furthermore, if the whistle sounds noisy, such as at night, turn the cover with the notch to prevent the sound from being emitted even when the piston of the driving member moves back and forth in the cylinder chamber of the whistle body due to the water flow. It is convenient because it allows you to
