AI Technical Summary
Technical Problem
In the use of flap-type drainers, the flap is difficult to remove in the existing technology, which leads to cleaning of the filter cartridge. Moreover, after the flap is opened, it is easily closed automatically by the impact of water flow or debris, affecting the stability of use.
Method used
The flap design employs a nested structure, using a combination of a magnetic dial and an inner support ring. The diameter of the inner support ring is controlled by rotating the dial, thus achieving stable opening and closing of the flap.
Benefits of technology
It enables stable opening and closing of the flap, facilitating filter cartridge cleaning and improving ease of use and stability.

Abstract
This utility model relates to the field of bathroom products and discloses a basin drainer. The structure includes an embedded tube for installation on a basin. The top opening of the embedded tube has an annular stabilizing groove. A flap is engaged in the stabilizing groove. The flap includes a dial, an inner support ring, and a water-proof ring. There are two dials that are magnetically attracted to each other. The inner support ring is nested between the dials. The water-proof ring is nested on the inner support ring. The flap is nested in the stabilizing groove through the water-proof ring. The two dials have the freedom to move closer or further apart. This utility model uses the attraction of the two dials to drive the inner support ring to nest the water-proof ring. By rotating the two dials, the two dials move closer to each other, controlling the diameter of the inner support ring to decrease. This causes the nested water-proof ring to contract, allowing the flap to be better removed from the stabilizing groove of the embedded tube. By rotating the dials, the two dials move further apart, allowing the two dials to open and press against the inner cavity opening, keeping the flap in a relatively stable vertical state.
