DRAINER

WIPO Patent Application WO/2021/128884

A1

A drainer, comprising: a first through pipe, a second through pipe, a deodorization basket, a water stop cover, and a drainer bounce core. Since an external force acts on the water stop cover, the drainer bounce core enables the water stop cover to pop out from a first opening of the deodorization basket in a direction distant from the water stop cover; the water stop cover opens the first opening of the deodorization basket, and water flows from the first opening of the deodorization basket to a sewer; the weight of water acts on a movable plate to drive the movable plate to move in a direction close to the first through pipe, so that a spring is stretched and deformed, and the movable plate opens a second opening of the deodorization basket; after the drainage is completed, the water does not act on the movable plate, the spring contracts to restore to a natural state, and the spring pulls the movable plate to move in a direction distant from the first through pipe such that the movable plate closes the second opening of the deodorization basket. The drainer in the present application can effectively overcome the technical defects of complex structures and poor deodorization effects of existing deodorization drainers.
