Patent ID: 8220492

Claim:
A faucet device comprising: a fixing unit including a fixing seat that has a water supply hole, and a switch seat that is coupled rotatably to said fixing seat, that is positioned relative to said fixing seat along an axis, and that has a locking groove, and a water inlet pipe extending from said switch seat and defining a guide channel therein; a valve unit including a hollow valve body that has a top portion formed with a water outlet, and a bottom portion formed with an internal surrounding surface, and a valve seat that is disposed in said valve body, and that has a coupling portion coupled separably to said water inlet pipe of said switch seat of said fixing unit, and a water inlet hole in fluid communication with said guide channel and said water outlet, said valve unit being movable along the axis between a first position, where said valve unit is connected to said fixing seat of said fixing unit, and a second position, where said valve unit is separated from said fixing seat; a positioning unit disposed for coupling separably said valve unit to said fixing unit, and including first and second positioning members provided respectively on said fixing unit and said valve unit, said valve unit being rotatable relative to said fixing unit from the first position in a first rotational direction so as to engage said second positioning member to said first positioning member, and to rotate said switch seat such that said guide channel in said water inlet pipe is aligned with said water supply hole in said fixing seat, said valve unit being further rotatable relative to said fixing unit back to the first position in a second rotational direction opposite to the first rotational direction so as to permit disengagement of said second positioning member from said first positioning member and movement of said valve unit from the first position to the second position, and to further rotate said switch seat such that said guide channel is misaligned with said water supply hole; and a locking unit including a locking component mounted pivotally to said fixing seat of said fixing unit and having a locking end portion and a driven end portion that is opposite to said locking end portion, said locking component being pivotable between a locking state, where said locking end portion engages said locking groove in said switch seat for locking said switch seat to said fixing seat, and a releasing state, where said locking end portion is disengaged from said locking groove, thereby permitting rotation of said switch seat relative to said fixing seat, and a resilient component disposed for biasing said locking component to pivot to the locking state; wherein said driven end portion of said locking component is pushed by said internal surrounding surface of said valve body of said valve unit to move said locking component from the locking state to the releasing state against a biasing force of said resilient component during movement of said valve unit from the second position to the first position.
