ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a kitchen use faucet structure.
2. Description of the Related Art
A conventional kitchen use faucet structure in accordance with the prior art comprises a fixed base secured on the sink of the kitchen, a faucet pivotally mounted on the fixed base, a cold water tube and a hot water tube each having a distal end extending through the fixed base and secured to a water introducing hole defined in the faucet to supply water into the faucet when the faucet is pivoted on the fixed base. However, the faucet cannot be conveniently pivoted on the fixed base due to interference of the cold water tube and the hot water tube so that when the faucet is pivoted to a determined angle, it will be pulled backward to an extent by the restoring action of the cold water tube and the hot water tube, thereby limiting the mobility of the faucet.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a kitchen use faucet structure comprising: a cylindrical fixed base having a lower end defining two fixed screw holes for locking the fixed base to a sink by two screws, a faucet having a lower end fitting hole for receiving the fixed base therein and having a screw hole for allowing passage of a locking screw which is secured in an annular limiting groove which is defined in an outer wall of a mediate portion of the fixed base so that the faucet is pivoted on the fixed base, the limiting groove having a top and a bottom each having an abutting step for supporting a slide sleeve which is slidable in an inner wall of the lower end fitting hole of the faucet for facilitating the faucet pivoting on the fixed base, the improvement comprising: the lower end of the fixed base being provided with two threaded introducing holes for securing the lower end of the fixed base to two cold/hot water tubes; a cold water introducing chamber defined in the fixed base and having an inlet connecting to one of the two introducing holes and an outlet extending to a top of the fixed base and provided with a cold flow tube protruding outward; a hot water introducing chamber defined in the fixed base and having an inlet connecting to the other of the two introducing holes and an outlet extending to the top of the fixed base and located adjacent to the cold flow tube; the cold flow tube and an upper end of the fixed base each having an outer wall defining an annular groove for receiving a sealing ring; a cold water fitting hole defined in a top of the lower end fitting hole of the faucet for receiving the cold flow tube, a cold water chamber defined in an upper end of the faucet and connecting to the cold water fitting hole, a hot water chamber defined in the top of the lower end fitting hole of the faucet and connecting to the outlet of the hot water introducing chamber, the cold water chamber and the hot water chamber each having an upper end defining a fitting hole for receiving two fitting posts of a control device.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
