Kind Code:
A1
Abstract:
Provided in the present application is a double-layer filtering water seal floor drain, which comprises a cylinder body, wherein a floor drain floor plate is arranged at the bottom end of the cylinder body; the floor drain floor plate is coaxially provided with a drainage pipe; a sealing cover located between the drainage pipe and the inner wall of the cylinder body is arranged in the cylinder body; the sealing cover is higher than the drainage pipe in the cylinder body; several drainage holes are provided in a side wall of the sealing cover; and a first grate and a second grate, which are located above the sealing cover, are arranged on the cylinder body. The first grate and the second grate provided have a double-layer filtering effect, thereby solving the problem in the background art of a single-layer filter screen plate being prone to blockage. By means of arranging the sealing cover, the drainage holes and the drainage pipe, insofar as drainage can be guaranteed, a water seal ring is autogenously formed, thereby preventing odor emission.
