AI Technical Summary
Existing odor-proof floor drains cannot effectively prevent odors from returning after water evaporates, thus affecting indoor air quality.
The combination of a flexible sealing sheet with folded edges and a water seal forming tube forms a double sealing structure, preventing moisture evaporation and maintaining the water seal effect.
It effectively prevents moisture evaporation, prolongs the odor-proof effect of the floor drain, improves sealing, and prevents odor leakage.

Abstract
Claims
1. A water evaporation preventing floor drain, characterized by: The device includes a water inlet assembly, a water seal forming pipe, and a drain body connected in sequence, as well as an elastic sealing sheet that seals the water seal forming pipe. A raised rib extends radially inward from the inner wall of the end of the water seal forming pipe, so that the elastic sealing sheet seals with the raised rib in the horizontal direction. The elastic sealing sheet extends along its edge to form a folded edge, so that the folded edge seals with the inner wall of the water seal forming pipe in the vertical direction.
2. A water evaporation preventing floor drain according to claim 1, wherein: The angle between the folded edge and the elastic sealing sheet is greater than 90 degrees.
3. A water evaporation preventing floor drain according to claim 2, wherein: The elastic sealing sheet is provided with several ribs that extend radially from the center to the edge.
4. A water evaporation preventing floor drain according to claim 1, wherein: The end of the water seal forming pipe is provided with a plurality of limiting rods extending radially along the central axis to the pipe wall. The connecting end of the plurality of limiting rods extends downward along the central axis to form a mounting post, and the elastic sealing sheet is fixed to the mounting post.
5. A water evaporation preventing floor drain according to claim 1, wherein: The outer wall of the end of the water seal forming pipe is provided with a groove for installing a sealing ring.
