DETAILED DESCRIPTION OF THE INVENTION

[0011] Referring to FIGS. 1 to 4, a faucet in accordance with a first preferred embodiment of the invention comprises the following components as discussed in detail below.

[0012] A faucet body 10 includes a channel 11 having a first end in fluid communication with an outlet of a filter (not shown), a sleeve 18 disposed on the channel 11 and secured to a sink (not shown), a curved faucet spigot 12 in fluid communication with a second end of the channel 11, a rotatable handle 15 configured to open or close the faucet spigot 12 and increase or decrease the volume of flow through the faucet spigot 12, and a fastening member 13 distal the faucet spigot 12 and proximate the handle 15.

[0013] A valve 20 includes an upper, hollow cylinder 21, a space 23 defined by the upper, hollow cylinder 21, a fastening element 22 disposed on a top of the upper, hollow cylinder 21 and configured to complementarily secure to the fastening member 13 by snapping, thereby fastening the faucet body 10 and the valve 20 together, a drain seat disposed on a bottom of the upper, hollow cylinder 21, a first hole 26 through a bottom of the drain seat 25 and having a first tunnel 261 through the drain seat 25, an inlet connector 30 secured to the first hole 26, a second hole 27 through the bottom of the drain seat 25 and having a second tunnel 271 through the drain seat 25, an outlet connector 40 secured to the second hole 27 and being in fluid communication with a drain pipe (not shown) of the filter, a curved tube 28 having a first end 281 secured to the first tunnel 261 and a second end 282 passing through the second tunnel 271 into the outlet connector 40, a gap 29 formed between the first end 281 and the inlet connector 30, and a vent 24 having a first end in fluid communication with the second tunnel 271 and a second end in fluid communication with an outer surface of the upper, hollow cylinder 21.

[0014] An outlet of unfiltered water of the filter is connected to the inlet connector 30 and the outlet connector 40 is connected to a drain (not shown). In operation, the unfiltered water of the filter flows through the inlet connector 30, the curved tube 28, and the outlet connector 40 into the drain. An air gap is formed at the second end of the vent 24 to prevent siphoning of the unfiltered water from the drain into the filter. Referring to FIG. 5, a faucet in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following: a top cap 231 is formed on a top of the upper, hollow cylinder 21. A bottom cap 232 is formed on a bottom of the upper, hollow cylinder 21. The sleeve 18 passes through the bottom cap 232 and the top cap 231. A passageway 280 is formed through the space 23, the first tunnel 261, and the second tunnel 271 for flowing unfiltered water. An air gap is formed at the second end of the vent 24 to prevent siphoning of the unfiltered water from the drain into the filter.

[0015] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
