Waterway adapter with multi-angle adjustment

Abstract

A waterway adapter with multi-angle adjustment includes a rotary joint, a connector, a rotating shaft, a turning block, an upper arm, and a position unit. A lifting rod rotates around the connector to adjust the distance from the wall. An upper-arm rotates around the rotating shaft and a shower head rotates with upper-arm accordingly for persons with different height.

What is claimed is: 
     
         1 . A waterway adapter with multi-angle adjustment, comprising:
 a rotary joint having a hollow body portion connecting to a water source, an axial first through hole, a longitudinally disposed recess, a first inlet and a first outlet connecting to the first inlet;   a connector positioned in the recess, comprising an axial second through hole to connect to the first through hole, a second inlet and a second outlet separated from the second inlet, wherein the second inlet is connected to the first outlet, and the connector fixes to a lifting rod;   a gasket having a hole and positioned between the second inlet and the first outlet for preventing a flow of the liquid;   a rotating shaft passing through the first through hole and the second through hole from one side of the connector to position the rotary joint and the connector for the connector rotating around the rotating shaft with the lifting rod, wherein the rotating shaft has a water chamber to connect with a third inlet and a third outlet, and the third inlet is connected to the second outlet for water conduction;   a turning block fitting into the rotary joint from another side of the rotating shaft to rotate around the rotating shaft, and having an adjustment element combining with the rotary joint;   an upper-arm having a rotary portion fitting into the turning block from another side of the rotating shaft to rotate around the rotating shaft with the turning block, the rotary portion having a fourth inlet and a fourth outlet connected to the fourth inlet internally, the fourth inlet connected to the third outlet, and fourth outlet connected to the water outlet, wherein a plastic ring is placed between the rotary portion and the turning block; and   a position unit entering into the rotating shaft from outside of the rotary portion for binding the rotary joint, the connector, the rotating shaft, the turning block, and the upper-arm together on axial direction.   
     
     
         2 . The waterway adapter with multi-angle adjustment as claimed in  claim 1 , wherein the rotary joint is a T tubular joint comprising: the first through hole and a longitudinally disposed recess, the first inlet connected to the water source, and the first outlet connected to the recess having a first end with a convex boss and a second end formed with a ring groove having a saw-toothed structure on the bottom thereof. 
     
     
         3 . The waterway adapter with multi-angle adjustment as claimed in  claim 2 , wherein the connector has one end with ring structure having the second through hole and another end forming a first tube portion and a second tube portion, the ring structure positioned in the recess and the outer edge of the ring structure having the second inlet with ring groove connected to the first tube portion, the inner arm of the ring structure having the second outlet connected to the second tube portion, and the second inlet connected to the first outlet. 
     
     
         4 . The waterway adapter with multi-angle adjustment as claimed in  claim 3 , wherein the gasket is an eye gasket withstanding the second inlet to seal the connection with the first outlet and having the hole for water passage; and two convex bosses on the eye gasket have two springs respectively for avoiding low pressure leaking from the connection. 
     
     
         5 . The waterway adapter with multi-angle adjustment as claimed in  claim 4 , wherein the rotating shaft passing through the first through hole and the second through hole of the hollow body portion is formed a groove on one end to contain convex bosses, and has the water chamber internally connecting to the third outlet and the third inlet which is connected to the second outlet of the connector for water flow. 
     
     
         6 . The waterway adapter with multi-angle adjustment as claimed in  claim 5 , wherein the turning block is ring structure with two sides, one side forming a serration to gear the saw-toothed structure of the rotary joint from another side of the rotating shaft for rotating around the rotating shaft with multi-angle adjustment. 
     
     
         7 . The waterway adapter with multi-angle adjustment as claimed in  claim 6 , wherein the rotary portion has one closed end with ring groove thereon, and the outer of the rotary portion fixes to the turning block and the inner of the rotary portion holds the rotating shaft to form an inner space for a connection of the fourth inlet and the third outlet. 
     
     
         8 . The waterway adapter with multi-angle adjustment as claimed in  claim 7 , wherein the plastic ring is placed between the rotary portion and the turning block, and the fourth outlet is connected to the water outlet. 
     
     
         9 . The waterway adapter with multi-angle adjustment as claimed in  claim 7 , wherein the position unit is a position pin entering the rotating shaft from outside of the rotary portion for binding the rotary joint, the connector, the rotating shaft, the turning block, and the upper arm together. 
     
     
         10 . The waterway adapter with multi-angle adjustment as claimed in  claim 1 , further including a lid located on the outside of the rotary joint, and a lid located on the outside of the rotary portion for securing the rotary joint and the upper-arm respectively. 
     
     
         11 . The waterway adapter with multi-angle adjustment as claimed in  claim 9 , wherein the connector is configured to bind to the rotary joint with a slot, and a bolt passes through the slot for limiting rotating angle of the connector around the rotary joint. 
     
     
         12 . A lifter for a waterway adapter with multi-angle adjustment, comprising:
 a lifting rod having a first flexible tube abutting to the first tube portion and a second flexible tube abutting to the second tube portion, both flexible tubes connected to a water separator;   an bending portion having a proximal end and a distal end, the distal end located on a wall to conduct a water source and the proximal end equipped with a rotary joint to connect to the lifting rod; and   an upper-arm connected to the lifting rod and having a proximal end and a distal end, the distal end equipped with a rotary portion to connect to the bending portion to receive water and the proximal end equipped with a shower head for water output.
