Description

FIELD OF THE INVENTION

[0001] The present invention relates to a faucet and more particularly to a faucet that is turned on/off by pressing.

BACKGROUND OF THE INVENTION

[0002] Generally, a conventional faucet has a main body (40), and a bottom portion and a top portion thereof respectively have a water inlet chamber and a water outlet chamber for connecting a water inlet tube (41) and a water outlet tube (42) (as shown in FIGS. 7 and 8). Moreover, a valve room (401) is communicated with and formed at a lateral side of the main body (40) for accommodating a control valve (43), and the control valve (43) is connected to and turned on/off by a handle (44). The filtered water can flow from the water inlet tube (41) through the main body (40) and out of the faucet from the water outlet tube (42).

[0003] However, the conventional faucet is disadvantageous because: (i) the handle (44) is connected to the lateral side of the main body (40), which leads that more space is required for installation; and (ii) after the main body (40) is manufactured, an additional process for manufacturing the valve room (401) is required, which increases the costs of time and effort. Therefore, there remains a need for a new and improved design for a faucet to overcome the problems presented above.

SUMMARY OF THE INVENTION

[0004] The present invention provides a faucet which comprises a main body, a control valve, a first press button and a second press button. 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. Moreover, 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 first press button and the second press button respectively. 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, wherein 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. Furthermore, 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, wherein 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 at a lateral side of a center axis of the driving valve piece. Each of the first press button and the second press button has a first end and a second end, and an outer periphery of the second end comprises a plurality of positioning portions. Moreover, the first press button and the second press button 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 first press button or the second press button is selectively pressed through the first end thereof to enable the second end to pass through the opening at the same lateral side, and the second end is adapted to push and shift the driving valve piece to enable 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 in the present invention.

[0005] Comparing with conventional faucet, the present invention is advantageous because: the faucet is operated through the first press button and the second press button, which reduces space required for installation; (ii) after manufacturing of the main body, there is no need to have an additional process for the valve room, which reduces the cost and labor; and (iii) the alignment between the water channel and the second through hole and the third through hole can be achieved through horizontally shifting the driving valve piece such that the manufacturer has no need to accurately calculate the rotation angles between the valve pieces, which makes the control valve easier to manufacture.
