Mouth thin film and trim ring constitute the check valve for making gas that inlet channel can only be entered by valve seat.Air vent thin film and screw are constituted
Prevent gas from being entered the check valve of inlet channel through air vent by outside.Conversion head is the first airway, semicircle inducing QI
Pipe is the second airway.
In other embodiment of the present utility model, inducing QI tube assembly can include the airway of three and more than three,
Each airway is hinged to collectively form inducing QI tube assembly, but the quantity of the preferred airway of this utility model is two or three
It is individual.
In other embodiment of the present utility model, only in side setting valve seat in cap shell, now conversion head quantity is one
Individual, the other end of semicircle airway is hanging, and the shape of semicircle airway can be other shapes, such as quadrant
Shape.
In other embodiment of the present utility model, air vent and aerofluxuss can be opened up in the other positions of inducing QI tube wall
Mouth check valve.But open up when being the corresponding position in gas outlet, during expiration gas drain into outside air time it is shorter.
In other embodiment of the present utility model, the gum cover in nasal obstruction can be cancelled, or directly protect nasal obstruction cancellation
The position of card gas outlet when in use just at nostril at.
In other embodiment of the present utility model, air vent and air vent check valve can be cancelled, user is being used
When, exhaled by mouth.
