Abstract

A faucet may comprise a main body, a control valve, and two press buttons. The main body is hollow to form a valve chamber therein, and the control valve is configured to be positioned in the valve chamber. A top end of the main body is connected to a water outlet tube, and a lower end thereof is configured to axially insert into the valve chamber. After the control valve is positioned in the valve chamber, a locking ring is engaged with and secured at a lower end of the valve chamber, and a water inlet tube is configured to axially penetrate through the locking ring to connect to the control valve. Each of two lateral sides of the main body has an installing hole, and two installing holes located at two corresponding positions are configured to receive and couple with the two press buttons respectively.

Claims

1. A faucet comprising a main body, a control valve, and two press buttons;

wherein the main body is hollow to form a valve chamber therein, and the control valve is configured to be positioned in the valve chamber;

a neck portion having a smaller diameter than the valve chamber is connected to and communicated with an upper end of the valve chamber;

a top end of the main body is connected to a water outlet tube, and a lower end of the water outlet tube is configured to axially insert through the neck portion into the valve chamber;

after the control valve is positioned in the valve chamber, a locking ring is engaged with and secured at a lower end of the valve chamber, and a water inlet tube is configured to axially penetrate through the locking ring to connect to the control valve;

each of two lateral sides of the main body has an installing hole which is communicated with the valve chamber, and the two installing holes located at two corresponding positions are configured to receive and couple with the two press buttons respectively;

wherein the control valve comprises a valve shell and a valve base which are configured to couple together, and a housing formed inside the valve shell is configured to accommodate an upper fixed valve piece, a driving valve piece and a lower fixed valve piece in sequence;

a connecting tube upwardly extending from a top end of the valve shell is communicated with the housing, and each of two lateral sides of the valve shell has an opening, and the two openings are located at two corresponding positions;

when the control valve is positioned in the valve chamber, the two openings are respectively aligned with the two installing holes, and the connecting tube is adapted to connect to the water outlet tube which is downwardly inserted into the valve chamber through the neck portion;

the upper fixed valve piece is secured in the housing while the lower fixed valve piece is secured at a top surface of the valve base;

a first through hole axially penetrates through a central portion of the valve base, and a second through hole and a third through hole respectively and axially penetrate through a central portion of the lower fixed valve piece and a central portion of the upper fixed valve piece, and the first through hole, the second through hole and the third through hole are aligned with each other;

the upper fixed valve piece, the driving valve piece and the lower fixed valve piece are stacked in sequence, and the driving valve piece is configured to be located at a position horizontally aligned with the openings;

a water channel is configured to axially penetrate through the driving valve piece; and

wherein each of the two press buttons has a first end and a second end, and an outer periphery of the second end comprises a plurality of positioning portions;

the two press buttons are configured to respectively connect to the two installing holes of the main body through the positioning positions on the two second ends thereof;

the two press buttons are alternatively pressed through the first ends thereof, and the second end of the pressed press button is configured to pass through the opening at the same lateral side and to push and shift the driving valve piece, which enables the water channel of the driving valve piece to partially align, completely align, or misalign with the second through hole of the lower fixed valve piece and the third through hole of the upper fixed valve piece simultaneously, thereby turning on/off and controlling the water amount of the faucet.

2. The faucet of claim 1, wherein an 0-ring and a locating ring are respectively disposed on an outer periphery of the lower end of the water outlet tube, and the locating ring is made of polytetrafluoroethylene (PTFE).

3. The faucet of claim 1, wherein each of the water inlet tube and the locking ring comprises a threaded section, and the water inlet tube and the locking ring are engaged together through the threaded sections thereon.

4. The faucet of claim 1, wherein an outer edge of the upper fixed valve piece has two first flat surfaces and two first recesses, which enable the upper fixed valve piece to be secured in the housing of the valve shell.

5. The faucet of claim 1, wherein an outer edge of the lower fixed valve piece has two second flat surfaces and two second recesses which enable the lower fixed valve piece to be secured at the top surface of the valve base.

6. The faucet of claim 1, wherein the water channel axially penetrating through the driving valve piece is located at a lateral side of a center axis of the driving valve piece.

7. The faucet of claim 1, wherein an outer edge of the driving valve piece has two third recesses at two corresponding positions, and two recess bottoms of the two third recesses are provided to be abutted against by the two second ends of the two press buttons respectively.

8. The faucet of claim 1, wherein three sealing rings are respectively disposed between the valve shell and the upper fixed valve piece, between the lower fixed valve piece and the valve base, and between the valve base and the water inlet tube.

9. The faucet of claim 1, wherein each of the third through hole, the water channel, and the second through hole has an elongate cross section.

10. The faucet of claim 1, wherein each of the two press buttons has a concave axially extending from the second end toward the first end thereof to form the press button in a cap shape, and the positioning portions on the second end are elastic claws.
