Description

BACKGROUND

Technical Field

[0001] The present invention relates generally to a sanitary ware, and more particularly to a shower column with a liftable showerhead.

Description of Related Art

[0002] Conventional showerheads generally have a hose connected to a faucet. During controlling the faucet to output water, a plurality of spraying holes of the showerhead sprays out water columns for users to shower. With the aforementioned showerhead, a showerhead holder of the showerhead is provided on a wall of a bathroom. When users would like to empty two hands for shower, the showerhead could be fixed to the showerhead holder. At this time, users could shower under the showerhead.

[0003] The conventional showerheads allow the showerhead to be fixed to the showerhead holder, thereby allowing users to shower freely. However, usually only one showerhead holder is provided on the wall, or only one showerhead holder is provided at high position and at low position respectively, so that the position of fixing the showerhead is restricted by the position of the showerhead holder, and the height of the showerhead cannot be adjusted freely, which causes inconveniences and limitations in use.

SUMMARY OF THE INVENTION

[0004] In view of the above, the primary objective of the present invention is to provide a shower column with a liftable showerhead, which could allow different users to freely adjust a height of the showerhead by providing a telescopic tube assembly connected to a water source and a showerhead.

[0005] The present invention provides a shower column with a liftable showerhead including a faucet, a top base, an outer rod, a telescopic tube assembly, and a showerhead structure. The faucet has a main body, wherein the main body has a first outlet hole. The top base has a connector and an upper base connected to the connector. The outer rod is a hollow tubing body, wherein two ends of the outer rod are engaged with the main body and the upper base respectively. The first outlet hole faces towards the outer rod. A front surface of the outer rod has an elongated hole which extends along a longitudinal direction of the outer rod. The telescopic tube assembly has an inner tube, wherein a bottom end of the inner tube along the longitudinal direction of the outer rod is engaged with the first outlet hole in a sealed way. A liftable tube slidably fits around the inner tube in a sealed way and has a liftable outlet hole communicating with the inner tube. A spring is provided inside the liftable tube and abuts against a top end of the inner tube along the longitudinal direction of the outer rod to be compressed by the liftable tube. The showerhead structure has a sprayhead and a connecting base connected to the sprayhead, wherein the sprayhead has a plurality of spraying holes. The connecting base has a connecting channel communicating with the spraying holes. The connecting base passes through the elongated hole and is detachably engaged with the liftable tube. The connecting channel communicates with the liftable outlet hole.

[0006] During installing of the present invention, the faucet and the top base are engaged with the wall of the bathroom. The faucet introduces the water source. When users need to shower, the height of the showerhead structure could be raised or lowered. During adjusting the height of the sprayhead, the liftable tube of the telescopic tube assembly would move with the height of the sprayhead, ensuring the continuous communication between the sprayhead and the water pathway in the telescopic tube assembly. After completing the adjustment of the height of the sprayhead, users control the faucet to control the first outlet hole to output water, allowing water to pass through the inner tube, the liftable tube, the liftable outlet hole, the connecting channel, and finally to be sprayed out from the spraying holes of the sprayhead for users to shower.

[0007] With the aforementioned design, the sprayhead of the showerhead structure could be raised or lowered by a certain height to meet various requirements of users at different heights. Alternatively, by adjusting the height of the water columns sprayed out from the sprayhead, users could focally rinse the destinated part, facilitating users to use.
