Long-acting totally-closed water seal type odor-resistant same-floor drainage floor drain

Abstract

The invention discloses a long-acting totally-closed water seal type odor-resistant same-floor drainage floor drain which comprises a same-floor floor drain main body, a floor drain grate and a water seal structure, wherein at least one pipeline joint is arranged on a side wall of the floor drain main body; the water seal structure is a water seal which is formed by a water seal outer sleeve and a water seal inner sleeve in a sleeving manner and has a vertical section shaped like a Chinese character shan; a protective floater with an air cavity is additionally arranged in a space between the lower end of the water seal inner sleeve and the bottom surface of the floor drain main body; a main body of the protective floater is a disc-shaped surface matched with an inner cavity of the water seal outer sleeve in inner diameter; multiple balance holes are formed in an area, which is close to the edge, on the disc-shaped surface along the periphery; the air cavity is raised in the water seal inner sleeve; the protective floater floats to an edge at the lower end of the water seal inner sleeve so as to close the lower end of the water seal inner sleeve; meanwhile, an annular water seal panel is arranged above the water seal outer sleeve and is arranged on the water seal inner sleeve in the sleeved manner; the annular water seal panel can be tightly contacted with the top end of the water seal outer sleeve; the upper end of a vertical water channel is closed; the water seal panel and the protective floater form a double-seal ring together, so that a water body in the water seal is remained for a long time, and the aim of water seal for a long time is achieved.

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 not well 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]② Limited by the height of the water seal, the floor drain is often relatively thick, which requires the building structure and the position of the standpipe, so it cannot be flexibly arranged during installation

[0007]③ Installation and maintenance are inconvenient: the existing floor drains cannot be completely disassembled or can only be partially disassembled, and the floor drain itself, especially the pipeline, is blocked during use. It cannot be disassembled for maintenance (dredging) and reinstalled for use, but can only be destructively removed, which makes 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
