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.

Claims

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).
