A long-term fully-enclosed water-sealed deodorant same-layer drainage floor drain

Abstract

The invention discloses a long-acting fully-enclosed water-sealed deodorant floor drain on the same floor, which comprises a floor drain body on the same floor, a floor drain grate and a water seal structure, the side wall of the floor drain body has at least one pipe interface, and the water seal structure is composed of The vertical section formed by the water seal outer sleeve and the water seal inner sleeve is a "mountain"-shaped water seal. A protective float with an air cavity is added in the space between the lower end of the water seal inner sleeve and the bottom surface of the main body of the floor drain. The main body of the protective float is a The disk surface is suitable for the inner diameter of the inner cavity of the water seal jacket, and the area near the edge of the disk surface is distributed with several balance holes along the periphery. edge to close the lower port of the water seal inner sleeve; at the same time, an annular water seal panel is set above the water seal outer sleeve, which is placed on the water seal inner sleeve and can be in close contact with the top of the water seal outer sleeve to close the vertical water channel. The upper port, together with the protective float, forms a double sealing ring, so as to retain the water body in the water seal for a long time, and achieve the purpose of long-term water sealing.

Description

technical field [0001] The invention relates to a same-floor drainage floor drain of a building drainage system, in particular to a fully-enclosed, water-sealed, deodorizing, same-floor floor drain. Background technique [0002] The floor drain is a common drainage component used in the drainage system in the construction field. It is an important interface connecting the drainage piping system with the indoor ground. The purpose of the floor drain is to remove ground water, filter solids, fibers, hair, easy sediments, etc. in the water, and at the same time, through the formed water seal, isolate the waste gas in the drainage pipe, which has the function of preventing the drainage pipe from clogging and deodorizing. [0003] In house decoration, the laying layer on the ground is often only 3~8cm, while the national standard GB50015-2003 "Code for Design of Water Supply and Drainage in Buildings" excerpt 4.5.9 stipulates that the height of the water seal should not be less t...

AI Technical Summary

Problems solved by technology

[0005] ① The floor drain is poorly sealed and has no anti-drying effect. The water in the water seal is easy to evaporate when there is no water replenishment for a long time, and cannot play the role of deodorization

[0006] ②Limited by the height of the water seal, the floor drain is often relatively thick, which has requirements for the building structure and the position of the standpipe, and cannot be flexibly arranged during installation

[0007] ③Inconvenient installation and maintenance: the existing various floor drains cannot be completely disassembled or can only be partially disassembled. When the floor drain itself is blocked during use, especially the pipeline, it cannot be disassembled, repaired (dredged) and reinstalled for use. Can be destructively removed, making installation and maintenance very inconvenient

[0008]④The anti-return water performance is poor. Although most of the existing floor drains are designed with anti-return water in mind, there are hooked hairs on the drainage channel in the floor drain. And the structure of the fiber, the hair and fiber are hooked during use, so that the anti-return water is invalid

[0009] ⑤ No barrier, smooth drainage effect is poor: Same as above, in the originally narrow drainage channel space, due to the structure and hooks of hair and fiber barriers during use , and the water passing area is further reduced, so the effect of smooth drainage cannot be achieved
