Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device which is attached to a tap of a water supply to save the outflow amount of the tap water.

“Conventional technology” Conventionally, the concentration of tap water has been increasing year by year due to the concentration of population in urban areas, resulting in a chronic shortage of water resources. For this reason, water shortage often occurs in the summer when the amount of rainfall is small and the amount of water used is large.

In order to limit the amount of tap water used, water is saved by replacing the water-stopping pieces used in ordinary currans with water-saving tops or by adjusting the outflow of the curran faucet.

"Problems to be solved by the device" Conventionally, in order to replace a water stopping piece of a water supply curran with a water saving piece, the lid part of the water supply currant is removed and replaced, but this replacement work is troublesome and troublesome. , I rarely exchanged for water-saving pieces.

Also, if the apparent outflow of water decreases for water users, it will take more time to wash them, making it difficult to keep water in a mood, and limiting the outflow of currants to limit the amount of water used. There were few people who did it, and in addition, there was a drawback that the opening degree of the faucet was different depending on the person.

The present invention has been made in view of the above-mentioned conventional drawbacks, and an object thereof is to attach it to a faucet of a currant to save a certain amount of water consumption, and even if it saves water, normal water is used. It is intended to provide a water-saving device in which water seems to be flowing out without feeling uncomfortable with the amount used.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a plurality of through holes in a radial direction in a resin upper body having an insertion hole at the center, and hooks at each through hole. The lower end of the faucet inserted into the insertion hole is attached to the center of the lower body that is attached to the upper body with a fastener that pushes the rear end of the latch pin while inserting the pin To form a tubular portion having a flow passage communicating with the flow passage, and to provide several spiral ridges on the inner surface of the tapered throttle portion continuously provided in the flow passage, A divergent opening is formed downward, and a small hole for sucking air is provided above the opening.

[Operation] A faucet for Karan is attached to the insertion hole of the upper body, the stop valve of the Karan is opened to limit the amount of water flowing out by the throttle section, and the spiral ridge provided in this throttle section can change the water flow into a swirling flow. Because it is possible, the apparent amount of water does not seem to save water. Moreover, the air taken in from the outside is taken into the water by using the pressure difference after passing through the constricted portion, and becomes a soft water flow.

[Embodiment] The first embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a water-saving device 1 includes an upper body 2 made of resin to be attached to a faucet 50 of a currant and a lower cylindrical body 10 for adjusting the flow rate of water.

A plurality of band-shaped fasteners 7 are formed at the rear ends of the latching pins 5 to push the latching pins 5 toward the center, and a step portion 8 is provided on the lower outer periphery of the upper body. The male screw portion 9 is formed to the lower part.

An annular groove portion 11 is provided on the upper surface of the lower body 10, a cylindrical portion 12 is formed at the center of the groove portion 11 so as to project upward, and a male screw portion 9 of the upper body 2 is screwed on the outer peripheral surface of the groove portion. A female screw portion (13) to be fitted is provided.

Reference numeral 14 denotes a flow passage provided in the tubular portion 12 of the lower body, which has the same inner diameter as that of the faucet 50, and has a valve opening 17 at the lower end of a tapered throttle portion 15 continuously provided at the lower portion of the tubular portion 12. And a divergent opening 18 is formed from the valve port 17 to the lower end of the lower body 10. The plurality of small holes 19 are located above the opening 18 and are communicated from the outer surface of the lower body 10 so as to be orthogonal to the wall surface of the opening.

In addition, several spiral ridges 16 are formed on the wall surface of the narrowed portion 15,
The water flow passing through the throttle portion 15 is swirled.

Compare the cross-sectional area of the faucet 50 of the Karan with the cross-sectional area of the valve opening 17.
Although it is formed by reducing it by 70%, it is not necessarily limited to 70%, and it is possible to set it to 60% or 80% as necessary.

Reference numeral 20 is an annular seal packing interposed between the lower end of the faucet 50 and the upper end of the tubular portion 12, and 7a is an operating lever provided on the fastener 7.

Referring to FIG. 4, the water saving device 31 of the second embodiment will be described. An insertion hole for inserting the faucet 50 into the center of the upper body 32.
33 is provided penetrating vertically. Above the upper body 32, tap
A plurality of through holes 36 for inserting the retaining pins 35 for fixing the 50 are formed toward the center, and a fastener 37 for pushing the rear end of the retaining pins 35 in the center direction is attached. Further, the female screw portion 34 is formed continuously under the insertion hole 33 provided in the upper body 32.

A male screw portion 41 is formed on the outer periphery of the upper portion of the lower body 40, a flow hole 44 having the same inner diameter as the faucet 50 is provided at the center, and a tapered narrowed portion 45 is continuously formed below the flow hole 44. At the lower end of the throttle, a valve opening with the cross-sectional area of the faucet 50 reduced by 70%
Formed 47. A divergent opening 48 is formed continuously with the valve opening 47, and a plurality of small holes 49 for air intake are provided in the upper portion of the opening 48. Although not shown in the drawing,
As in the embodiment, a plurality of spiral ridges are formed.

Next, the operation of the embodiment will be described with reference to the first embodiment. In order to attach the water-saving device 1 to the currant, the operation lever 7a is used.
Is operated to loosen the fastening tool 7, and then the faucet 50 is inserted into the insertion hole 3 of the upper body 2 from above, and the seal packing 20 is interposed between the tubular portion 12 and the faucet 50. Next, the operating lever 7a is operated to tighten the fastener 7, and the rear end of the latch pin 5 is pushed into the through hole so that the tip of the latch pin 5 abuts the outer peripheral surface of the faucet 50 to save the water-saving device 1. Fix on the curran.

When water is used by fully opening the stop valve (not shown) of the Karan, the water flowing out from the faucet 50 passes through the flow passage 14 in the tubular portion 12,
While being swung by the spiral ridge 16, the pressure is increased by being narrowed by the throttle portion 15 and the valve opening 17 formed to have a cross-sectional area reduced to 70% of the cross-sectional area of the faucet 50 reduces the flow rate Narrow down to 70%.

The swirling water flow that has passed through the valve port 17 has a divergent opening 18
The outer shape of the water flow is enlarged along the wall surface of the water and flows out from the lower end of the opening 18 while swirling.

By spreading the water flow in the opening 18, the apparent thickness of the water flow flowing out from the lower end of the opening is almost the same as usual, so that there is no feeling of water saving. Further, when the water flow moves from the small-diameter valve port 17 to the large-diameter opening 18, the pressure is reduced, and by this pressure reduction, the external air is taken in from the small hole 19 to mix air bubbles into the water, and a soft water flow can be obtained.

The water-saving device 31 of the second embodiment is the same as the water-saving device of the first embodiment, except that a male screw portion 44 is provided on the outer peripheral surface of the lower body 38,
Since the female screw portion 34 provided on the inner wall of the insertion hole 33 of the upper body 32 is screwed and connected, a small-sized instrument having a simple structure and a light weight can be provided at low cost.

The water-saving devices 1 and 31 of the first and second embodiments have a water-saving function when 70% or more of the full stop valve of Karan flows out. Further, when the opening degree of the stop valve of the Karan is adjusted to save water and the force of the water flow is weak, the water saving function does not work, and the flow rate from the faucet flows out through the openings 18 and 48 as it is.

Further, as the fastener for attaching the upper body of the water-saving device 1, 31 of the first and second embodiments to the faucet, other known fasteners can be used, and the upper body 2, 32 can be attached to the faucet 50. It is also possible to form integrally with.

"Effect of Invention" The present invention has the following effects.

Since the throttle portion having a diameter smaller than the inner diameter of the faucet is provided in the flow path of the lower body, the water flow from the currant can be saved at a constant rate by the throttle portion, the cost can be reduced, and the waste of water resources can be prevented.

The spiral ridge provided on the inner wall of the throttle restricts the linear water flow into a swirling flow, and after passing through the valve port, it becomes a large diameter water flow despite the small amount of water used. Has an advantage that it does not cause discomfort due to water saving and does not cause resistance to use of water saving equipment.

Due to the pressure difference when the water flows into the large-diameter opening from the narrowed portion, the air taken in from the outside can be mixed into the water to form a soft water flow, and the bounce can be prevented.
