Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
As shown in Figure 1, a kind of ventilator provided in this embodiment imports and exports protective device, including lid 1；The one of lid 1
End face is equipped with annular connecting column 11；The end face of the back ring shape connecting column of lid 1 is equipped with cylindrical slot 12, is inserted in cylindrical slot 12 suitable
The closure column 13 matched blocks column 13 and is adapted to the inner wall of annular connecting column 11.In addition, blocking the end of the back ring shape connecting column of column 13
Face is equipped with and screws block 14, convenient for closure column 13 is screwed and pullled.
The ventilator imports and exports protective device by carrying out the design of annular connecting column 11 and cylindrical slot 12 to lid 1, when
When ventilator is stored, the annular connecting column 11 of lid 1 is convenient for the air inlet of air inlet pipe and the outlet of escape pipe of ventilator
It is attached and blocks the good protection, it can be achieved that ventilator entry/exit port, efficiently avoid outside air and pass through entry/exit
Port enters inside ventilator, at the same also avoid disinfection when thimerosal be trapped at the entry/exit port of ventilator；Work as ventilator
In use, removing the closure column 13 placed in cylindrical slot 12, closure column 13 is plugged in the inner wall of annular connecting column 11, can avoid
Annular connecting column 11 is contaminated when unused, is disinfected again when avoiding the use of annular connecting column 11 of lid 1
Process, improve practicability.
The inner wall of annular connecting column 11 is equipped with internal screw thread 111, blocks column 13 and is equipped with external screw thread, blocks column 13 and connect with annular
Column 11 is threadedly coupled；Convenient for the connection of annular connecting column 11 and closure column 13, avoids and block column 13 from annular connecting column 11
The phenomenon that falling.It blocks column 13 to be threadedly coupled with the cylindrical slot of lid 1, convenient for the connection of lid 1 and closure column 13, avoids envelope
The phenomenon that stifled column 13 is fallen from lid.In addition, the annular remote lid end of connecting column 11 is equipped with loop buffer pad 112, loop buffer
The size of pad 112 is consistent with the annular size of connecting column 11.When the air inlet pipe or escape pipe of annular connecting column 11 and ventilator
When connection, the ladder bottom surface of annular connecting column 11 and air inlet pipe or escape pipe offsets, and loop buffer pad 112 is located at annular even
It connects and plays good sealing function between column 11 and air inlet pipe or the ladder bottom surface of escape pipe.
The utility model as shown in Figures 2 and 3 additionally provides a kind of ventilator, including above-mentioned ventilator inlet and outlet protection dress
It sets, further includes ventilator ontology 2；Ventilator ontology 2 is equipped with air inlet pipe 21 and escape pipe 22, air inlet pipe 21 and escape pipe 22
Outside is connect with the annular connecting column 11 of lid 1；And the connecting pin of air inlet pipe 21 and escape pipe 22 is stepped, annular connection
The connecting pin of column 11 and the ladder bottom surface of air inlet pipe 21 or escape pipe 22 offset.Pass through the air inlet pipe 21 and outlet to ventilator
Pipe 22 is adapted to lid respectively, consequently facilitating the air inlet pipe 21 and escape pipe 22 to ventilator block, efficiently avoids outer
Portion's air enters pollution caused by inside ventilator by entry/exit port.The connecting pin of air inlet pipe 21 and escape pipe 22 is in rank
The design of scalariform, convenient for offseting with the connecting end surface or loop buffer pad of annular connecting column 11, and then improve air inlet pipe or
Escape pipe connect with annular connecting column after leakproofness.
In addition, the side wall of air inlet pipe 21 and the side wall of corresponding lid are connected by connecting line, the side wall of escape pipe 22 with
The side wall of corresponding lid is connected by connecting line；It avoids to leave about when lid 1 is not used and leads to the phenomenon that losing.Air inlet pipe 21
It is equipped with external screw thread with the outside of escape pipe 22, the annular connecting column 11 and air inlet pipe or escape pipe of lid 1 are connected by screw thread
It connects；Effective compact connection convenient for annular connecting column 11 and air inlet pipe perhaps escape pipe avoids lid 2 from air inlet pipe or goes out
Lead to the phenomenon that falling off due to plugging not in place at tracheae.
It should be noted that preferred embodiment above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should be managed
Solution: it can still modify to technical solution documented by previous embodiment, or to some or all of technologies
Feature is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and the utility model is real
The range of a technical solution is applied, should all be covered in the claim of the utility model and the range of specification.
