BACKGROUND
Field of the Invention
The present invention relates to faucets, and more particularly to a dual-purpose faucet that, apart from serving the conventional purpose of discharging water therefrom, is designed to discharge a water jet from a dedicated spout wherein, the trajectory of the water jet is adjustable so as to be convenient for drinking.
As water is an indispensible part of one's life, faucets are indispensible part of one's household. Faucets are installed in various places within a household such as, in kitchen, bathroom, lavatory, dining room, etc., and serve a multitude of purposes such as, cooking, shaving, brushing, washing hands, etc. Owing to the fact that water is discharged from a downspout in a downward direction, there is however one need that is unmet by a conventional faucet, which is enabling one to directly drink, rinse one's mouth (during brushing), etc., from the downspout without the need for using a cup or ‘cupping’ one's hands. Therefore, in the light of this one unmet need, it would be advantageous to have a faucet to discharge water upwardly into an arc shape whereby, one can conveniently place one's open mouth directly in the line of the stream of the discharged water so as to fill one mouth with it for the purposes aforementioned. Better yet would be to have such a faucet that, apart from discharging water in the aforementioned manner, enables one to adjust the trajectory of the water jet to suit one's individual preferences such as, height, convenience, etc.
SUMMARY
The present invention comprises a dual-purpose faucet that, apart from discharging water from its downspout, generates a parabolic water jet from a dedicated fountain spout so as to enable a user to directly drink the water from the water jet. The faucet comprises a ball valve for blocking the free end of the faucet. A fountain check valve is provided, which includes the aforementioned fountain spout, such that, the fountain check valve is sensitive to a threshold pressure. As the water is being discharged from the downspout of the faucet, and at this point, as the free end of the faucet is blocked by the ball valve, the backpressure created as a result thereof, upon reaching a threshold pressure, enables fountain check valve to open and eventually discharge a water jet therefrom.
Other objects and advantages of the embodiments herein will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION
In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.
The present invention comprises a dual-purpose faucet that, apart from conventionally discharging water from its downspout for utilitarian purposes, discharges a water jet (or water fountain) from a dedicated fountain spout so as to enable a user to drink water directly from the water jet without the need for using a cup, or the like. Further, a control means is employed by the faucet so as to enable the user to adjust the trajectory of the water jet to suit his/her individual preferences such as, height, convenience, etc., so as to be convenient for drinking.
Referring to FIGS. 1 and 3, the faucet 10 comprises a substantially inverted U-shaped faucet pipe 12 fitted from to a water source. The faucet pipe 12 is preferably of uniform annular cross-section. The free end of the faucet pipe 12 is fitted with a ball valve 14 comprising conventional ball valve components comprising a holed ball 16 disposed between a pair of seats washers 18 within the faucet pipe, and a handle 20 for operation disposed preferably at the side of the faucet pipe 12 as seen in FIG. 1. Notably, the ball valve 14 makes up the aforementioned control means wherein, the manipulation of the trajectory of the water jet by the operation of the ball valve 14 will become apparent from the following body of text. The ball valve 14, as known in the art, is operable between a closed and an open position wherein, the discharge of water from the faucet pipe 12 is allowed in the open position, and blocked in the closed position. Additionally, a faucet aerator may be fitted to the free end of the faucet pipe 12 (past the ball valve 14) for obvious reasons.
Referring to FIGS. 1, 2, 4 through 8, the faucet 10 further comprises a fountain check valve 22, which comprises a spring-loaded ball check valve comprising a substantially cylindrical fountain spout 24 for discharging the water jet therefrom. The upper portion of the fountain spout 24 extends upwardly through curved upper surface of the faucet pipe 12, while the rest of the fountain spout 24 is disposed within the faucet pipe 12. A portion of the surface of the faucet pipe 12 around the upper portion of the fountain spout 24 (that extends upwardly through the faucet pipe 12) is elevated such that, the upper end of the fountain spout 24 is flush with the elevated surface of the faucet pipe 12. The fountain spout 24, as seen in FIGS. 2 and 4, is forwardly tilted so as to enable the water jet 26 to be discharged in the forward direction, more particularly, in the shape of an inverted parabola as seen in FIG. 5.
Referring to FIGS. 2, 4, 6 through 8, the fountain check valve 22 further comprises a dowel pin 28 that laterally extends through the upper portion of the fountain spout 24 such that, the dowel pin 28 is perpendicular to the longitudinal axis of the fountain spout 24. A top end of a compression spring 30 is secured to the dowel pin 28 while the rest of the compression spring 30 is disposed within the fountain spout 24. The fountain check valve 22 further comprises an O-ring 32 slidably disposed within the fountain spout 24 wherein, the O-ring 32 is sealingly disposed within the fountain spout 24 as the perimeter thereof abuts the inner surface of the fountain spout 24. A spherical block ball 34 is seated over the O-ring 32 as the lower end of the compression spring 30 is pressed against the block ball 34 so as to seal the ingress of water into the fountain spout 24.
Still referring to FIGS. 2, 4, 6 through 8, the fountain check valve 22 further comprises a set nut 36 threadably secured within the fountain spout 24 at the bottom end thereof such that, the O-ring 32 rests over the set nut 36. The set nut 36 is adapted to be threadably movable so as to advance the set nut 36 in the upward and downward directions in order to regulate the force exerted by the compression spring 30 on the block ball 34 and therefore, in turn, regulate the threshold pressure required to open the fountain check valve 22. Notably, as the set nut 36 is threadably moved upward, the force exerted by the compression spring 30 on the block ball 34 gradually increases and as, the set nut 36 is threadably moved downward, the force exerted by the compression spring 30 on the block ball 34 gradually decreases.
Referring to FIGS. 9 through 11, as water 38 is being discharged from the downspout 40 of the faucet 10, as the ball valve 14 is closed, as well known in the art, a backpressure is created within the faucet pipe 12. The backpressure, upon reaching a threshold pressure (as regulated by the set nut 36), which normally ranges between 20 to 150 psi, causes the block ball 34 to be elevated off the O-ring 32 at which point, the water enters the fountain spout 24 so as to be eventually discharged therefrom as a water jet 26 as seen in FIG. 11. At this point, as the ball valve 14 is regulated by moving the handle 20 thereof between the closed and open position, the backpressure is simultaneously regulated so as to adjust the trajectory of the water jet 26 such as, the height, range of the water jet 26, etc.
Although, the water jet from the fountain spout is adapted to range past the faucet, there is still a good chance of the water from the fountain spout wetting the surface of the faucet pipe leading to water spotting. In order to prevent this, the exterior of the faucet pipe has a matte finish. In an alternate embodiment, the exterior surface of the faucet pipe has a physical vapor deposition (PVD) finish to not only prevent the surface of the faucet from water spotting but also from the formation of tarnish, scratches, corrosion, etc. For hygienic reasons, the faucet of the present invention, when used in hospitals, hotels, etc., the opening of the fountain spout may be sealed with a tape when not in use.
