Description

Technical Field

[0001] This utility model belongs to the field of kitchenware technology, and in particular relates to a basin drain mechanism. Background Technology

[0002] In existing washbasin drainage systems, the connection between the adapter pipe and the second pipe is relatively traditional, typically using a screw-in connection, such as a threaded connection. This connection method fixes the angle and relative position between the second and first pipes, lacking flexibility. In practical applications, the installation location of washbasins and the surrounding space layout vary, and drainage systems with fixed angles and positions cannot meet diverse installation needs, causing numerous inconveniences during installation. Especially under narrow or specially laid-out washbasins, fixed-angle drain pipes are prone to interfering with surrounding pipes, requiring additional elbow fittings to adjust the route, increasing installation complexity. Furthermore, threaded connections are prone to loosening or seal failure over long-term use, leading to leakage risks, and impurities can easily accumulate in the thread gaps, affecting drainage efficiency.
