Corresponding small air inlet hole, the end of hollow out section are provided with a conduit, and tube at one end connection conducting hollow out section, the other end, which is inserted into, to be kept away
Dead band, sealing is packed into an appendix in empty avoiding section, and the empty avoiding section is around the ventilation circle setting of tube body one, the outer wall of appendix
It is adhesively fixed by the outer wall of glue and elastic rubber layer inner wall and tube body of divulging information.
The conduit is U-shaped as a preferred technical solution, every appendix piece conduit of equal face, the conduit
Both ends open, be internally provided with an inlet channel, air cleaning filler, the air inlet of inlet channel filled in the inlet channel
Mouth end and outlet port pass through a sealing net environmental sealing.
The air cleaning filler is absorbent charcoal material as a preferred technical solution,.
The centre of the appendix is provided with a gas distribution channel as a preferred technical solution, and the two of gas distribution channel
End opening, inlet port are inserted into empty avoiding section, and gas outlet section stretches out in the outside of ventilation tube body.
The beneficial effects of the utility model are: the utility model structure is simple, elastic rubber can be utilized when not in use
Layer automatic-sealed entrance end, can be effectively isolated interior or exterior space, increase thermal insulation property, especially ventilation shaft usage quantity compared with
Big occasion；And U-shaped conduit is utilized, enable to the air of discharge to realize preferably purification.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the inner section schematic diagram of the utility model；
Fig. 2 is the external end view of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including a ventilation tube body 5, the inside of ventilation tube body 5 have an air-inlet cavity 4, air-inlet cavity 4
Outlet port closing, the external of ventilation tube body 5 wrap up one layer of elastic rubber layer 1,1 inner wall of elastic rubber layer and ventilation tube body 5
Between be provided with glue layer 2, elastic rubber layer 1 is bonded in the outside of ventilation tube body 5 by glue layer 2, and the centre of glue layer 2 is set
It is equipped with one section of hollow out section L, faces and is provided with corresponding small air inlet hole 8 on the ventilation tube body 5 of hollow out section L, the end of hollow out section L
It is provided with a conduit 6,6 one end of conduit connection conducting hollow out section L, the other end is inserted into empty avoiding section 7, and sealing fills in empty avoiding section 7
Enter an appendix 3, empty avoiding section 7 passes through glue and elastic rubber layer 1 around the ventilation circle setting of tube body one, the outer wall of appendix 3
