AI Technical Summary
The use of sealing components in existing kitchen drain systems increases installation difficulty and material costs.
A novel drain device is designed, in which the isolation cover controls the flow or blockage of the drain outlet through the linkage of the support foot and the filter bag, and forms a sealing structure by combining the sealing edge. The isolation cover is integrally molded by injection molding and does not require additional sealing components.
It simplifies the installation process, reduces material costs, and effectively prevents residue and residual water from flowing back, thus reducing the frequency of cleaning.
