Floor drain

Abstract

The invention discloses a floor drain, which is used for being mounted on a sewer pipe, and comprises a floor drain core and a turning plate, wherein the floor drain core is used for being inserted into the sewer pipe and is provided with a water outlet at the bottom end; the turning plate is hinged to the floor drain core around the rotating axis; a sealing part matched with the water outlet in shape so as to seal the water outlet is arranged on one side of the rotating axis; a first straight edge and a second straight edge are arranged on the two sides, perpendicular to the rotating axis, of the outer edge of the sealing part; and the maximum distance between the first straight edge and the second straight edge is configured to be equal to the maximum projection width of the sealing part on the rotating axis, so that the first straight edge and the second straight edge do not interfere with the inner wall of the sewer pipe in the rotating range of the turning plate. According to the floor drain, the sealing part is arranged on the turning plate, and the straight edges are arranged on the two sides of the sealing part, so that the two straight edges on the turning plate can ensure that the turning plate cannot interfere with the sewer pipe in advance within the rotating range of the turning plate while the water outlet area of the water outlet of the floor drain core is increased as much as possible.

Description

technical field [0001] The invention relates to the technical field, in particular to a floor drain. Background technique [0002] In the existing floor drains, in order to prevent the water from overflowing or the sewage pipeline from recoiling, a flap is installed at the water outlet of the floor drain core. When the water is not passing through, it will automatically turn up and block the water outlet of the floor drain core, and at the same time, it can be turned down under the force of the water flow when the floor drain is passing through the water without affecting the flow of water. In order to ensure that the existing floor drain core has a sufficient water-passing area, when the diameter of the floor drain core is constant, its cross-sectional shape generally needs to be consistent with the cross-sectional shape of the downpipe, that is, it is roughly circular. A flap is installed so that the floor drain core cannot be completely adapted to the downpipe, and it is...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the water flow of the anti-odor floor drain, it is necessary to increase the water passing area of ​​the outlet of the floor drain core as much as possible. As the area of ​​the water outlet increases, the size of the flap also increases, which will make it easier for the flap to interfere with the inner wall of the downpipe prematurely when it is turned down. This interference will cause the flap to not be fully opened, that is, The flap cannot be fully opened to its maximum angular position, which reduces the water flow
