Drain apparatus with branch tube and valve
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.

BACKGROUND OF THE INVENTIONThe previous Thai Patent application No. 071847 reveals the invention of drain apparatus with branch tube and valve to remove blockage in the drain. The cylindrical apparatus is made in two identical pieces to be attached to each other to form a tube. The material used is plastic. This has caused several defects as follows:
1. Rugged and uneven surface
2. Leak
3. Uneven connection point
4. Fragile
The present Invention acknowledged these defects and is consequently produced with improved characteristics to achieve greater and more efficient result.
This Invention is related to Civil Engineering
BRIEF SUMMARY OF THE INVENTIONThe cylindrical body of the Drain Apparatus is composed of 2 parts, which are the outer tube and the inner tube. The outer tube is a manufactured in one piece with small tube branching on its side; while the inner tube is composed of 2 pieces attached to each other to form a tube with a valve affixed inside. The inner tube which is relatively smaller than the outer tube is to be inserted into the outer tube with a lock to prevent movement without use of glue or other means of connection.
The primary objective of this Invention is to remove blockage and waste in the drain, using the power of water pressure or air pressure. Moreover, this unique, simplified and effective Invention will help to increase convenience in life, save time, money and labor from the traditional blockage removing methods. More importantly, it helps protect the environment and dispose the waste properly with absolutely no use of chemical substance.
With use of this environment-friendly Invention, it is not required to disassemble the drain or use chemical substance to corrode the drain, causing severe damage to the environment.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING
Therefore, the water or air cannot flow upwards, but will flow downwards to remove blockage and waste in 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).
