Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a faucet-mounted water-saving device that can be attached to a faucet (including a faucet such as an instantaneous water heater) to save water.

[0002]

[Prior art]

 Conventionally, when tap water is used, a faucet with a stop valve is used because it is necessary to turn it on and off. Conventional faucets (16 to 19 mmφ) have a relatively large diameter, which wastes a large amount of water. Therefore, in some cases, water is being saved while squeezing the faucet.

[0003]

[Problems to be solved by the device]

 However, using tap water while squeezing the faucet has a problem that the amount of squeeze varies each time it is operated, and it is necessary to take water out while considering the amount of squeeze, which is extremely troublesome. Therefore, if the diameter near the outlet of the water faucet was partially reduced, the amount of water would certainly decrease, but there was the problem that the flow of water would become extremely fast and it would be difficult to use. In addition, if a valve is installed in front of the faucet to reduce the amount of water flowing, the water flow from the faucet will be weakened, and there will be a problem in use. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a faucet-mounted water-saving device that can save water without reducing the force of water.

[0004]

[Means for Solving the Problems]

 The faucet-mounting water-saving device according to claim 1, which is in accordance with the above object, and a faucet mounting part to be mounted on the faucet, a tapered narrowed part downstream of the faucet mounting part and having a reduced diameter. It has a foam metal fitting having a plurality of nets inside, which has a diameter on the downstream side of the section. Further, the faucet-mounted water-saving device according to claim 2 is the faucet-mounted water-saving device according to claim 1, further comprising a stepped portion having a reduced diameter downstream of the tapered throttle portion for adjusting the flow rate. Section is provided.

[0005]

[Action]

 In the faucet-mounting type water-saving device according to claim 1 or 2, the faucet mounting portion on the upper side is attached to the faucet, and the tapered throttle portion on the downstream side thereof reduces the amount of water without weakening the force of water. I am trying. And since it has a foam metal fitting with multiple nets in the lower part, this reduces the momentum a little, but since the momentum is strong, more air bubbles are mixed in than in the normal case, and This does not weaken the momentum of the water, which allows a relatively strong running water to be obtained with less water. In particular, in the faucet-mounted water-saving device according to the second aspect, a spool for adjusting the flow rate can be further inserted, whereby further water saving can be performed.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a sectional view of a faucet-mounting type water-saving device according to an embodiment of the present invention, FIG. 2 is a perspective view of a mounting ring, and FIG. 3 is a perspective view showing a method of mounting the faucet-mounting type water-saving device. 4 is a perspective view of a faucet mounting portion according to another embodiment, and FIG. 5 is a sectional view showing a state in which a spool is inserted therein.

As shown in FIG. 1, a faucet-mounting water-saving device 10 according to an embodiment of the present invention includes a faucet mounting part 11 to be mounted on the faucet, a throttle part 12 located downstream of the faucet mounting part 11. It has a spool housing portion 13 formed on the downstream side of the throttle portion 12 and a foam metal fitting 14 mounted on the lower portion. These will be described in detail below.

The faucet-mounted water-saving tool 10 is made of a synthetic resin such as heat-resistant ABS except for the rubber packings 15 and 16 disposed in the lower portion and the middle portion excluding the foam metal fitting 14. The upper faucet mounting portion 11 has a mounting ring 19 for mounting on the faucet 18 having a bulge 17 at the end, a mounting screw 21 for mounting the mounting ring 19 on the water-saving device body 20, and an internal packing 15. I will do it. The attachment ring 19 has a notch 22 and 23 inside which is partially cut off, and is expanded in diameter and attached to the faucet 18, and the attachment ring 19 is preliminarily attached to the faucet 18 to save water. The faucet-mounted water-saving tool 10 is fixed to the faucet body 20 and fixed to the faucet 18. The packing 15 is in close contact with the end of the faucet 18 so that water does not leak from the surroundings.

The narrowed portion 12 has a tapered shape, and the diameter thereof is gradually reduced to about 1/2, so that the resistance can be increased and the flow rate can be reduced without quenching the flow of tap water. . A spool accommodating portion 13 is provided below the throttle portion 12, and as shown in FIG. 5, a spool 25 having a hooking protrusion 24 on the side facing the inside is arranged. By inserting the spool 25, the passage area is extremely reduced, and the flow rate is extremely reduced.

The foam metal fitting 14 includes a middle container 28 having nets 26 and 27 provided at the bottom thereof, and a net body 29 provided at an upper diameter expanded portion of the middle container 28 at the upper portion thereof. And an outer cylindrical body 31 for screwing the inner container 28 to the water-saving device body 20, and water from the upper portion passes through a net body 29 to When ejected from the small holes of the ejection part 30, air is drawn in through an opening 32 formed around the middle part of the middle container 28, and bubbles water is discharged through the nets 26, 27 at the bottom. It has become.

FIG. 4 shows an attachment ring 33 and a packing 34 that engages with the faucet mounting portion 11 according to another example of the faucet-mounted water-saving device. As shown in FIG. The ring 33 is configured such that the faucet-mounting type water-saving tool can be attached to the faucet in which the end of the faucet is a male screw.

An experiment was conducted to confirm the action and effect when the faucet-mounted water-saving device 10 was used, but as a result of using it in a normal home, it was compared with the case where the faucet-mounted water-saving device 10 was not used. Then, it was found that an average of 28% of water can be saved without slowing down the power of water, and an average of 58% of water can be saved by inserting the spool 25 inside as shown in FIG.

[0013]

[Effect of device]

 The faucet-installed water-saving device according to the present invention is provided with a taper-shaped throttle portion that is downwardly reduced in diameter downstream of the faucet mounting portion, thereby reducing water while increasing the force of water, and further downstream of the throttle portion. Since it has a foam metal fitting that is on the side and has an expanded diameter and multiple nets inside it, a large amount of air bubbles are entrained in the reduced water, so that the momentum of the water is not attenuated. In the case of washing with water, it has the same washing effect as a normal faucet. Therefore, the faucet-mounted water-saving device according to the present invention saves water and contributes to the effective use of water, and also reduces the burden of water charges.
