Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a drain. Background Art

[0002] The traditional sink drain is equipped with a filter and a cover. When storing water, the cover blocks the drain, and when draining water, the cover is opened. During long-term use, since the filter and the cover are independent, the cover is easy to lose, and it is inconvenient to use. For this reason, a combined drainer has appeared on the market, in which the filter room and the blocking part are combined together, which is convenient to use and not easy to lose. However, the existing combined drainer has a relatively complex structure, especially its bouncing movement, which generally adopts a steel hook and a circulation groove structure, which is not only difficult to form, but also difficult to assemble.
