Abstract

A shower column with a liftable showerhead includes a faucet and a top base in which are connected by an outer rod. The faucet has a first outlet hole facing the outer rod. A front of the outer rod has an elongated hole extending along a top-bottom direction. An inner tube is engaged with the first outlet hole. A liftable tube slidably fits around an inner tube. A spring is provided between the liftable tube and the inner tube. A connecting base passes through the elongated hole and is connected between the liftable tube and a sprayhead of a showerhead structure. The sprayhead has several spraying holes communicating with an inside of the liftable tube. When using the present invention, the faucet and top base are engaged with a wall.

First claim

What is claimed is:

1 . A shower column with a liftable showerhead, comprising:
a faucet having a main body, wherein the main body has a first outlet hole; a top base having a connector and an upper base connected to the connector; an outer rod which is a tube 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, and a front surface of the outer rod has an elongated hole which extends along a longitudinal direction of the outer rod; a telescopic tube assembly having 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; and a showerhead structure having 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; wherein a recess is formed on a front side, which faces towards the elongated hole, of a top portion of the liftable tube, which is away from the faucet; a bottom side of the recess along the longitudinal direction of the outer rod has a locking groove; the recess has a connecting surface facing towards the elongated hole; the liftable outlet hole passes through a middle of the connecting surface; an engaging screw hole is provided on the connecting surface which is above the liftable outlet hole in the longitudinal direction of the outer rod; the connecting base has a connecting tube facing towards the liftable outlet hole, wherein the connecting channel passes through the connecting tube; a bottom portion of the connecting tube which faces towards the faucet has a protrusion and the protrusion is inserted to the locking groove; the connecting tube communicates with the liftable outlet hole; a protruding member is disposed on a top portion of the connecting tube opposite to the faucet and has a through hole which passes through the protruding member along a direction from the liftable outlet hole to the connecting tube; an engaging screw passes through the through hole to be engaged with the engaging screw hole.

2 . The shower column with the liftable showerhead as claimed in claim 1 , wherein a front surface of the connecting base which is away from the elongated hole has a first curved surface which curves along a top-bottom direction; the connecting channel passes through a middle of the first curved surface, wherein a left side and a right side of the first curved surface extend two pivot arm in a direction away from the elongated hole, an outer axial hole horizontally passes through two pivot arms; the sprayhead has a head and a pivot base connected to a rear end of the head which faces towards the connecting base, wherein the pivot base is provided between the two pivot arms and has a second curved surface facing towards the connecting base; a annular gasket is held between the second curved surface and the first curved surface; the spraying holes are provided at the head, and a delivering channel is formed in the pivot base; a front end of the delivering channel facing towards the head communicates with the spraying holes, and a rear end of the delivering channel facing towards the connecting base passes through a middle of the second curved surface; the delivering channel communicates with the connecting channel in a sealed way; an inner axial hole horizontally passes through two sides of the pivot base; a middle of the inner axial hole communicates with the delivering channel, and two ends of inner axial hole connects and communicates with the outer axial hole; a bolt and nut assembly passes through and is engaged with the outer axial hole and inner axial hole, wherein a middle of the bolt and nut assembly forms a neck at a position matching with the delivering channel.

3 . The shower column with the liftable showerhead as claimed in claim 1 , wherein the main body has a valve and an inlet hole communicating with the first outlet hole which is controlled by the valve; the inlet hole faces towards the outer rod; an inlet channel is formed in the connector and the upper base; an inlet pipe is provided in the outer rod, wherein a top end of the inlet pipe away from the faucet is connected to a front end of the inlet channel which faces towards the top base in a sealed way, and a bottom end of the inlet pipe which faces towards the faucet is engaged with the inlet hole in a sealed way.
