Odor-resistant floor drain having double turnover panels

Abstract

The invention provides an odor-resistant floor drain having double turnover panels. The floor drain comprises a cylinder. Two rotating shafts are symmetrically arranged on the outer side wall at the lower end of the cylinder. One end of each rotating shaft is vertically connected to the lower end of the outer side wall of the cylinder. The two symmetric turnover panels are rotatably arranged on the rotating shafts. The shape of the two turnover panels matches the shape of the cross section of the cylinder. The edge on one side of each turnover panel is in contact with the bottom of the cylinder, and the other side of the turnover panel is in rotatable connection with the rotating shafts. The odor-resistant floor drain having the double turnover panels is simple in structure, can increase the draining sectional area as the draining pressure increases, has good draining effects, has a long service lifetime, and is easy to clean.

Description

technical field [0001] The invention belongs to the field of drainage pipes, in particular to a double-flap anti-odor floor drain with a large drainage cross-sectional area. Background technique [0002] Civil buildings in my country all use sewer pipes with an inner diameter of 50mm. In order to avoid pipeline blockage, U-shaped deodorant bends are generally not installed, so users need to install deodorant floor drains in their houses. The current sealing methods of the deodorant floor drain generally have two forms of water sealing and valve sealing, or both sealing structures are used at the same time. [0003] The commonly used floor drain standard in the prior art is generally a square structure of 100*1000mm2, and the capacity of the cup body is limited. Due to natural evaporation, the sealed cup generally dries up in a day or two and loses its sealing effect. However, the deep-submerged U-shaped drainage bay has a small drainage cross-section and is easy to block. ...

AI Technical Summary

Problems solved by technology

This kind of floor drain has many disadvantages. First, according to the density of plastic and metal blocks, the two counterweights will occupy more than 50% of the drainage section.

The second is that the flap opens from the diameter position to the edge, and the opening angle is limited by the inner diameter of the sewer pipe, so it cannot be fully opened

The third is that the life span is only a few months, and the service life is short
