Embodiment Construction

[0007] The following structural examples and accompanying drawings further describe the present invention, but are not intended to limit the present invention.

[0008] There is an edge on the top of the drain made of metal or plastic, and a slope sealing sleeve is placed on the bottom of the drain edge, which is made of rubber. There are three double-slope grooves on the lower part of the drain. The high-elasticity flat sealing sewer soft cover is made of high-elastic rubber, and its side edges are glued together by bonding or pressing, and the middle is tightly pressed together to form a seal. The outer lower part of the high-elasticity flat sealing sewer cover is equipped with a sheath, and the side edges of the sheath and the side edges of the high-elasticity flat sealing sewer cover are bonded together by methods such as bonding or pressing. There is an extruded sleeve between the high-elasticity flat-sealed soft sleeve and the sheath, the upper edge of the extruded sleev...

Abstract

The invention relates to a device for preventing backwater and odor for an indoor outfall, belonging to the building drainage field. The invention comprises a sewer outlet (1), a sewer outlet edge (3), a bevel sleeve gasket (4) which is covered on the lower part of the sewer outlet edge, three double-bevel grooves (4), high elastic flat hermetic sewer soft sleeves (5) with the upper parts covered on the positions of the three double-bevel grooves, sleeve skins (6) which are adhered on the lower parts outside a plane of the high elastic flat hermetic sewer soft sleeves, and collapsing sleeves (7) which are fixed between the sleeve skins and the soft sleeves. The device for preventing backwater and odor for the indoor outfall has the advantages of simple structure, low manufacturing cost, fast drainage, water conservation, backwater and odor prevention and good sealing effect, enables a lavatory pan, a urinal, a basin, a vegetable sink, a mop sink and so on to save a drain trap, thereby saving materials and facilitating the dredging of the sewer.

Description

technical field [0001] The invention belongs to the technical field of building drainage. Background technique [0002] At present, the bowl-shaped sinks used indoors are odor-proof floor drains, toilets, urinals, and water seals are easy to breed bacteria and waste water resources. When the main sewer pipe is blocked, it will cause water to return to the room, and the water in the sink will return to the room after being evaporated. Contents of the invention [0003] The purpose of the present invention is to provide a powerful anti-return water and odor return device for floor drains, toilets, urinals and mop pools. [0004] The technical scheme of the present invention is (1) the drain port (2) the drain port along its function is to make the drain port hang on the drain outlet (3) the drain port has a slope sealing sleeve on the lower coat, which seals and fixes the drain port The function of the nozzle (4) There are three double-slope grooves in the lower part of th...
