Fluid flow control device for faucet {FLUID FLOW REGULATOR FOR FAUCET}

The present invention relates to a fluid flow control device for a faucet, and more specifically, it is mounted on the water outlet of the faucet, in addition to the basic function of smoothly discharging the discharged water, flow rate (step flow), flow rate, hydraulic pressure, and water flow The present invention relates to a fluid flow control device for a faucet, which is an aerator that can be easily adjusted to size, easy to manufacture, improve productivity and reduce manufacturing cost, and allows easy and robust installation.

In general, when you use a faucet (that is, faucet) in a public facility or at home, a large amount of water flows unconsciously, and waste water is unwanted. To save wasted water, adjust the amount of water by adjusting the handle of the faucet each time.

However, it is very inconvenient for the user to use water by adjusting the handle of the faucet at a fine angle, and it takes time and effort to adjust the fine angle every time it is used. Since water is discharged and wasted between adjusting the handle of the faucet, it is difficult to achieve substantial water saving.

As an example of a conventional device for controlling the amount of water discharged from the water discharge port attached to the end of the water discharge port in a faucet such as a faucet for washing face, the Republic of Korea Utility Model No. 20-209234 described in the prior art document below (Announced on January 16, 2001).

However, such a conventional device has a disadvantage in that it has many components and a complicated structure, and is very inconvenient for a user to control the amount of water discharge.

As a method to solve this problem, the Republic of Korea Utility Model Registration No. 20-0462332 (2012.09.06. Announcement) "water saving device" has been proposed.

However, the domestic registered utility model No. 20-0462332 (announced on June 6, 2012) aims to control the amount of water discharged, and the water discharged by the nozzle and the dispenser is separated and discharged, but the final discharged water is When combined, there is a problem that the thickness of the water is not uniform and is not discharged finely (shower type).

On the other hand, an aerator (aerator) is a mechanism that allows the user to have a soft feeling when using water and a function to prevent the water being discharged from splashing into several branches by smoothing the flow of water when water is discharged from the tap. In addition, the aerator also provides a function to save water by preventing excessive discharge of water per unit time. In fact, a survey conducted in Germany found that when a faucet is equipped with an aerator, water savings of about 50% occur.

When a conventional aerator is installed and used in a water outlet of a faucet, the user complains of great inconvenience in a situation where a lot of water is required. For this reason, such a saving aerator has been reduced to a meaningless device by rebuilding the saving aerator with a general aerator.

And the conventional method of setting by adjusting the main angle valve is a great inconvenience because the user must bow down to the lower part of the washbowl whenever it is used to obtain the desired flow rate.

In this way, when using a faucet such as a faucet, a water-saving device (water-saving adapter or fluid flow control for faucet fittings) that can conveniently set and fix the desired amount of water by saving water flowing without meaning by personal habits and places of use Device), and research and development on this are required.

Republic of Korea Registered Utility Model Publication 20-0209234 (Announcement of January 16, 2001) Republic of Korea Registered Utility Model Publication 20-0457942 (2012.01.12. Notice) Republic of Korea Utility Model Publication 20-0462332 (2012.09.06. Republic of Korea Registered Patent Publication 10-1135338 (Apr. 17, 2012)
