Description
Technical field
The utility model belongs to the gutter field, especially relates to a kind of gutter and prevents returning dirty interface.
Background technology
Pond of the prior art sewage drainage pipe anti-returns dirty structure, adopt the trap structure, in the sewer process, dirt can remain in pipe bent position, causes gutter to stop up, sewage is overflowed, use the worry bowl dirt can not be removed fully, trap can only be opened, clear up, but the trap place is narrow, not easy to clean.Simultaneously, if long-time unmanned in the family, water can evaporate disappearance in the trap, just the dirty gas in the sewer can enter within doors along pipeline.Also having a kind of gutter is the float-ball type gutter, though can play antifouling effect, in case dirt stops up unusual easy to clean not.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, be easy to install, do not stop up, anti-ly return dirty gutter.
The technical solution of the utility model is:
A kind of gutter prevents returning dirty interface, comprise internal channel and outer tunnel, described outer tunnel comprises upper end, reducing end, lower end and is provided with the bottom of standby drain hole, described upper end extends upward from the outside of described reducing end, extend downwards from the inboard of described reducing end described lower end, described bottom extends internally from the downside of described lower end, described internal channel is positioned at outer tunnel, and connect as one by described bottom and outer tunnel, the top of described lower end is provided with a sealing ring, and the lower part is with the antifouling sealing bag of sewer.
The outer wall of described lower end is provided with some annular projections.
Described internal channel lower end also comprises prolonging manages, and described prolongation pipe and internal channel are concentric.
Also comprise top cover, described top cover is provided with hole and card, and described top cover is connected with outer tunnel by screw thread.
Advantage and the good effect that the utlity model has are:
1. adopt the moisture film that forms between the antifouling sealing bag tube wall of sewer to seal, moisture film does not evaporate for a long time, has guaranteed better sealing effectiveness, and has removed trap, has prevented the dirt blocking problem.
2. the space that surrounds between internal channel and the outer tunnel can be conveniently with various electrical equipment in the kitchen, and as the kitchen treasured etc., the moisture of generation is discharged, and when gutter and this sealing structure were tight, infiltration also can be by the standby drain hole discharge under the outer tunnel.
3. be satisfied with to install, the mounting means between gutter and this structure and this structure and the sewer pipe is direct insertion, simple installation, easy access and replacing.

The specific embodiment
Embodiment one
Arrive shown in Figure 2 as Fig. 1, a kind of internal channel of the utility model prevents returning dirty structure, comprise internal channel 1, outer tunnel 2, described outer tunnel 2 comprises upper end 3, reducing end 4, lower end 5 and the bottom 6 that is provided with standby drain hole 7, described upper end 3 extends upward from the outside of described reducing end 4, extend downwards from the inboard of described reducing end 4 described lower end 5, described bottom 6 extends internally from the downside of described lower end 5, described internal channel 1 is positioned at outer tunnel 2, and connect as one by described bottom 6 and outer tunnel 2, the top of described lower end 5 is provided with a sealing ring 8, and the lower part is with the antifouling sealing bag 15 of sewer.The outer wall of described lower end 5 is provided with some annular projections 9, and the main effect of annular projection 9 is the frictional force that increases between antifouling sealing bag 15 of sewer and the lower end 5, makes antifouling sealing bag 15 difficult drop-offs of sewer.Described internal channel 1 lower end also comprises prolonging manages 14, and described prolongation pipe 14 and internal channel 1 are concentric, and the antifouling sealing bag 15 of the bottom of described prolongation pipe 14 and sewer contacts, and when sewage need be discharged, can not return dirt from standby drain hole 7.
As shown in Figure 5, internal channel described in the embodiment 1 prevents returning dirty structure, being fit to sewage drainage pipe 16 is under the situation of straight tube, its mounting means is as follows, this structure is directly inserted in the sewer mouth 17, sealing ring 8 and sewer mouth 17 Elastic Contact are directly inserted sewage drainage pipe 16 in the internal channel 1 then and are got final product.
