Plastic pipeline structure in faucet

Abstract

A plastic pipeline structure may include a channeling tube, two plugs, and a cover. The channeling tube can be manufactured in a single mold with plastic materials and has a mixing base in the middle, which has one or more outlet channels. The outlet channels in the mixing base and the channels in the horizontal tubes toward both sides are connected and formed in a perpendicular manner. Each horizontal tube has an open end and a vertical tube is perpendicularly connected with each horizontal tube near the open end. Each plug is inserted into the open end of each horizontal tube. The cover placed above the channeling tube has hole through which the mixing base can be connected with a faucet. There is a blocking surface formed on the interior wall of each side of the cover to block the plugs.

What is claimed is: 
     
         1 . A plastic pipeline structure comprising a channeling tube, two plugs and a cover,
 wherein the channeling tube can be manufactured in a single mold with plastic materials; the channeling tube has a mixing base in the middle, which has one or more outlet channels; the outlet channels in the mixing base and the channels in the horizontal tubes toward both sides are connected and formed in a perpendicular manner; each horizontal tube has an open end and is perpendicularly connected with a vertical tube near the open end; and an inlet channel is disposed inside each vertical tube that is parallel to the outlet channels in the mixing base;   wherein the plugs are inserted into the open ends of the horizontal tubes; and   wherein the cover is placed above the channeling tube; the cover has a hole through which the mixing base can be connected with a faucet; and there is a blocking surface formed on the interior wall of each side of the cover to block the plugs.   
     
     
         2 . The plastic pipeline structure of  claim 1 , wherein the top portion of the mixing base is threaded and therefore the mixing base can be connected with a faucet. 
     
     
         3 . The plastic pipeline structure of  claim 1 , wherein the vertical tubes are threaded and therefore the vertical tubes can be connected with external water lines. 
     
     
         4 . The plastic pipeline structure of  claim 1 , wherein each vertical tube is connected with a valve base along the vertical axis and the valve base has an outlet channel connected with the inlet channel in the vertical tube. 
     
     
         5 . The plastic pipeline structure of  claim 1 , wherein the plug has a head at one end and a plug body at the other end; the plug body is inserted into the open end of the horizontal tube and the head is blocked by the blocking surface of the cover. 
     
     
         6 . The plastic pipeline structure of  claim 5 , wherein the one or more grooves are formed on the surface of the plug body and a sealing gasket is placed in each groove. 
     
     
         7 . The plastic pipeline structure of  claim 5 , wherein the channeling tube has one or more engaging parts near each open end and each plug body has one or more connecting parts on the surface of the plug body; the connecting parts are engaged with the engaging parts when the plug body is inserted in to the open end of the horizontal tube. 
     
     
         8 . The plastic pipeline structure of  claim 7 , wherein the engaging parts are restricting holes and the connecting parts are blocks that mate with the restricting holes; the blocks are engaged with the restricting holes when the plug body is inserted into the open end of the horizontal tube.
