Document Type and Number:
WIPO Patent Application WO/2019/029441
Kind Code:
A1
Abstract:
A drainage assembly, comprising: a drainage pipe (100), the drainage pipe (100) comprising: a water receiving tank (110) that is disposed at a top portion, as well as a pipeline (120) that is in communication with the water receiving tank (110), a bottom end of the pipeline (120) being provided with a water outlet port (121); a valve (200), which may be assembled into the pipeline (120) from the water outlet port (121); the valve (200) comprises a base and a protruding column (220) that protrudes upward from the base (210), a plug being formed on the protruding column (220); the outer diameter of the plug (221) is adapted to the inner diameter of the pipeline (120), and at least one position groove is formed along the radial direction of the edge of the plug so as to be inwardly concave, a flow guide channel being formed between the groove and an inner wall of the pipeline (120). By means of the valve (200), the present invention enables the plug (221) and the inner wall of the pipeline (120) to cooperatively generate the flow guide channel (222) without altering the diameter of the drainage pipe (100) so as to discharge water; furthermore, the size of the water outlet port (121) is controlled, thus reducing the amount of air that flows back into the pipe and simultaneously ensuring smooth water discharge; the present invention is simple, convenient and reduces production costs.
