Drain apparatus with branch tube and valve

Abstract

The disclosed Drain Apparatus with Branch Tube and Valve is a cylindrical tube consisting of the outer tube ( 1 ) and inner tube ( 13 ). The bottom part of the outer tube ( 1 ) has 2 locks ( 4 ) ( 5 ) to prevent the movement when inserting the inner tube ( 13 ) into the outer tube ( 1 ). The upper part of the inner tube ( 13 ) has a hole ( 8 ) of similar size to the branch tube ( 2 ), branching from the outer tube ( 1 ), to allow high-pressure water or air flow through the inner tube ( 13 ). Above the hole ( 8 ), a valve ( 6 ) is mounted inside the inner tube ( 13 ). In its normal position, the valve ( 6 ) will perfectly close the end of the hole ( 8 ). When high-pressure water or air flows in, the valve ( 6 ) will be pushed upwards to close the upper opening. The water or air will flow along to push blockage and waste out of the drain.

1 . This detachable Drain Apparatus with Branch Tube and Valve to remove waste in the drain has the unique characteristic: it can be detached into 2 parts, which are the outer tube and inner tube.  
   
   
       2 . The one-pieced outer tube is of cylindrical shape consisting of the branch tube ( 2 ) branching from the upper part of the outer tube ( 1 ) to allow air or water to flow in and remove waste in the drain.  
   
   
       3 . Following claim No.  2 , there are two locks ( 4 ) and ( 5 ) at the bottom part of the outer tube ( 1 ) to support the inner tube when inserted into the outer tube.  
   
   
       4 . The inner tube consists of 2 pieces. Each piece is identical. When assembled together, it forms a cylindrical inner tube ( 13 ) which is slightly smaller than the outer tube ( 1 ). It can be inserted into the outer tube ( 1 ).  
   
   
       5 . The inner tube ( 13 ), as claimed in claim No.  4 , has a hole ( 8 ) to allow air or water inflow  
   
   
       6 . On the inner tube ( 13 ), as claimed in claim No.  4  or  5 , there is a valve ( 6 ) affixed inside the inner tube ( 13 ) above the hole ( 8 ). In normal position, the valve ( 6 ) will close the hole ( 8 )  
   
   
       7 . As claimed in claim No.  4 , 5  or  6 , when the inner tube ( 13 ) is inserted into the outer tube ( 1 ), the hole ( 8 ) of the inner tube ( 13 ) will be in the same position as the branch tube ( 2 ) of the outer tube ( 1 ). When the valve ( 6 ) is open, air or water will flow through the branch tube ( 2 ) and the hole ( 8 ) into the inner tube ( 13 ). High pressure of air or water flow will push the valve ( 6 ) to couple with the valve seat ( 7 ) and close the upper opening. Air or water flow, blocked from going upwards, will then go downwards to remove waste or blockage in the drain.  
   
   
       8 . As claimed in claim No.  4 , 5  or  6 , when the inner tube ( 13 ) is inserted into the outer tube ( 1 ), the small buttons ( 11 ) ( 12 ) of the inner tube ( 13 ) will couple with the locks ( 4 )( 5 ) of the inner tube ( 1 ) respectively. This will firmly lock the outer tube ( 1 ) to be attached with the inner tube ( 13 ).
