Compared with the prior art, the invention has the following advantages:
1. according to the floor drain provided by the invention, through the cooperation of the outer cylinder and the inner cylinder, water flows into the inner cylinder from the grate hole on the top plate of the inner cylinder and flows into the outer cylinder through the bottom opening of the inner cylinder during water drainage, the inner part of the inner cylinder is level with the liquid level in the overflow space and rises at the same time, when the liquid level in the overflow space rises to the position of the overflow hole, water is discharged from the overflow hole into the water drainage pipeline, and in the process, the position communicated between the bottom of the inner cylinder and the bottom of the outer cylinder is always blocked by water, so that the floor drain has very good sealing performance, so that gas and fungus in the water drainage pipe cannot return to a building room through the communication position between the inner cylinder and the outer cylinder, the phenomenon of returning smell is effectively avoided, and the effect of preventing fungus and insect is achieved.
2. The floor drain provided by the invention has the advantages that the inner core and the outer cylinder are detachably connected, so that the floor drain is convenient to install and the outer cylinder and the inner core are easy to clean.
3. According to the floor drain provided by the invention, through the grate holes on the inner core and the overflow holes on the outer cylinder, two filtering structures are equivalently arranged, so that the filtering effect of the floor drain can be greatly improved, and the situation that the drainage pipeline is blocked due to hair entering the drainage pipeline is reduced.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention.
