Water-saving nozzle mountable on a faucet
11000864 · 2021-05-11 · ·

The method is for discharging water through a faucet. The nozzle is attachable to a faucet and switchable between a spray-mode and a mist-mode. An inner cavity has filters and a water rotating device. The housing has an opening defined therein in fluid communication with the inner cavity and grooves and an orifice at a bottom portion thereof. The second filter is disposed below the opening. When in the spray-mode, water flows out through the opening and through grooves and is discharged as spray and mist at a bottom of nozzle. When switched to the mist mode, water only flow through the second filter but not through the opening. Water flows through the water rotating device to create a rotation of the water and the rotating water is discharged through the orifice as mist.
