A method of using a water-saving device for a faucet, the water-saving device having
- a main body having
- an assembling recess defined in a top surface of the main body;
- an assembling part protruding from a central part of a bottom surface of the assembling recess and having a flowing hole defined through the assembling part;
- a flange protruding radially from an outer surface of the main body;
- a connecting hole defined in a bottom surface of the main body and communicating with the flowing hole;
- and
- multiple receiving holes defined radially through the main body, spaced apart at intervals, and communicating with the assembling recess, and the receiving holes disposed corresponding to the assembling part in position;
- a flow-controlling member mounted in the assembling recess of the main body, and a bottom surface of the flow-controlling member abutting an inner surface of the assembling recess, the flow-controlling member having
- a passage hole defined through a central part of a top surface of the flow-controlling member and disposed corresponding to the flowing hole of the assembling part in position;
- a first through hole defined through a central part of the bottom surface of the flow-controlling member and communicating with the passage hole, the first through hole disposed corresponding to the flowing hole in position;
- and
- multiple second through holes defined annularly through the bottom surface of the flow-controlling member, spaced apart at intervals, and communicating with the passage hole;
- a flow-blocking member mounted movably and tightly between the assembling recess of the main body and the assembling part, and a top surface of the flow-blocking member being capable of closing the second through holes of the flow-controlling member, the flow-blocking member having
- an assembling hole defined through the flow-blocking member and receiving tightly an outer surface of the assembling part;
- and
- a rounded part formed in an annular edge of a bottom surface of the flow-blocking member;
- multiple positioning balls mounted respectively in the receiving holes, and each positioning ball being capable of abutting the rounded part of the flow-blocking member;
- and
- a driving member movably receiving the outer surface of the main body and having
- a mounting hole defined through the driving member;
- a first accommodating recess defined in an inner surface of the mounting hole, and a bottom surface of the first accommodating recess being capable of abutting the flange of the main body;
- and
- a second accommodating recess defined in the inner surface of the mounting hole, disposed at an interval relative to the first accommodating recess and being capable of receiving the positioning balls;
- the method of using the water-saving device comprising:
- mounting the water-saving device in an outlet of a faucet;
- opening the faucet to provide a water flow to the water-saving device;
- the water flow passing through the passage hole and the first through hole of the flow-controlling member and the flowing hole of the assembling part of the main body and departing from the water-saving device;
- pulling the driving member downwards for increasing the water flow;
- the flange of the main body departing from the first accommodating recess of the driving member;
- the water flow passing through the second through holes of the flow-controlling member and pressing the flow-blocking member to move downwards to the bottom surface of the assembling recess of the main body;
- the rounded part of the flow-blocking member abutting the positioning balls to extend out of the outer surface of the main body;
- the positioning balls mounted in the second accommodating recess of the driving member;
- the water flow passing through the passage hole, the first through hole, and the second through holes of the flow-controlling member;
- the flow-blocking member mounted in the bottom surface of the assembling recess;
- the increasing water flow passing through the passage hole, the first through hole and the second through holes of the flow-controlling member, the flowing hole of the assembling part and departing from the water-saving device;
- closing the faucet to stop the water flow passing through the water-saving device;
- the flow-blocking member departing from the bottom surface of the assembling recess and moving upwards;
- the flow-blocking member enclosing the second through holes of the flow-controlling member;
- the positioning balls departing from the second accommodating recess of the driving member and mounted in the receiving holes of the main body;
- the driving member moving upwards, and the bottom surface of the first accommodating recess abutting the flange of the main body;
- and
- the positioning balls abutting the rounded part of the flow-blocking member.
