Title: Water-saving faucet bracket
Inventor: CHA YOON DO
IPC: E03C1/04
Filed: 2020-08-07
Abstract: The present invention relates to a water-saving faucet. In a faucet including a mixing chamber in which cold water and hot water are introduced and which has a temperature control valve on one side thereof, a cartridge therein, and an outlet, and a faucet tap connected to the outlet to discharge mixed water, a water-saving part is formed between the mixing chamber and the faucet tap to discharge the mixed water for a certain time. The water-saving part has an inlet corresponding to the outlet at an upper part thereof and first and second blocking members therein, and the faucet tap and a shower hose corresponding to the first and second blocking members are connected to a lower part thereof. In addition, pressing members of the first and second blocking members protrude to the outside of the water-saving part, and inflow and outflow holes are opened by the pressing and fixing of the pressing members, and water is supplied to the faucet tap and the shower hose. The pressing members are restored to the original state by water pressure so that the inflow and outflow holes are intermittently shut off to block the water supply. The first and second blocking members are provided with the different elastic forces of an elastic part to restore the pressing members to the original state by water pressure so that the water supply time of the faucet tap and the shower hose is different. At this time, the water-saving part is formed in a rectangular box having a space therein and is formed with fixing parts on both sides to which the bodies of the first and second blocking members are screwed. Accordingly, by adjusting the time at which water is discharged to the faucet tap and the shower differently, water saving efficiency is improved as well as by adjusting the time at which water is discharged from the faucet tap and shower, the inconvenience of repeatedly pressing an opening and closing member when used for a long time is prevented.
