Three, spraying ball is arranged in the top of outlet tube, and the present invention realizes following advantages by above structure；
(1) present invention in use, user can mouth contain hose one and blow, gas enters from inlet tube one lives
In the bottle body one at one top of plug, since exhaust part row of exhausting-gas hole goes out, gas is less, so that the piston one inside bottle body one is to moving down
Dynamic and pressed home spring, and piston one moves down the piston two moved downwards through inside piston rod promotion medical fluid adapter cavity
It moves down, due to bottom to the top of piston two that the flow direction of check valve two is piston two, the flow direction of check valve one is drug storage
Inside intracavitary portion to medical fluid adapter cavity, so that the medical fluid inside two lower section medical fluid adapter cavity of piston is entered by inlet tube two
Inside the medical fluid adapter cavity of two top of piston, when user stops blowing, under the action of reset spring, reset spring, which pushes, lives
Plug one moves up, and the gas in one top bottle body one of piston is gone out to be discharged from gas vent, while passing through piston rod band piston
Two move up, and when piston two moves up, the medical fluid inside liquid storage chamber will enter piston by hose and inlet tube one
It inside two lower section medical fluid adapter cavities, is supplemented, while the medical fluid inside liquid storage chamber is being entered into medical fluid transition below piston two
While intracavitary portion, since the flow direction of check valve three is U-tube to spraying ball, it can make inside two top medical fluid adapter cavity of piston
Medical fluid import outlet tube from U-tube and spray misty medical fluid from spraying ball, at this moment just air-breathing can inhale misty medical fluid human body
Enter in nasal cavity, when human body is blown again, nasal cavity stops suction, and it is identical as above-mentioned principle, in this whole process, nasal cavity air-breathing
Gas is discharged in mouth, prevents user's habituation from exhaling by nasal cavity air-breathing, nasal cavity drug is discharged, cause to waste and reach
Less than good therapeutic effect, and using the mouth discharge more sucking gases of gas mostly with the successional characteristic of breathing,
Gas is discharged in mouth and provides the power of compression for the present invention, when stopping exhaling, atomized medicine is sprayed in the power release of compression
Out, atomized medicine can be sucked in nasal cavity along with human body air-breathing, while drug discharge and amount and mouth discharge gas flow are in just
Than voluntarily being controlled by user.
(2) present invention by pushing block in application, can make rotating disk rotate, and then adjust rotating disk sector outlet portion and gear
Plate fan-shaped pylone degree of engagement, i.e. degree of engagement is big, and gas vent makes piston one when rising more, and resistance reduces, and the rate of climb is accelerated,
Therefore two speed of piston is caused also to be accelerated, so that the speed of discharge atomized medicine is accelerated, to adjust atomized medicine discharge
Speed adapts to different crowds and uses.

Spraying ball 14, spraying ball 14 are hollow structure, and are uniformly arranged liquid outlet, the flow direction of check valve 1 on spraying 14 lateral wall of ball
For, to inside medical fluid adapter cavity 5, the flow direction of check valve 26 is bottom to the top of piston 2 19 of piston 2 19 inside drug storage chamber 2
Portion, the flow direction of check valve 3 12 are U-tube 7 to spraying ball 14, and the flow direction of check valve 4 15 is in hose 2 17 to bottle body 28
Portion.
Working principle: the present invention in use, user can mouth contain hose 1 and blow, gas is from inlet tube
One 16 enter in the bottle body 1 of the top of pistons 1, more into gas since to go out gas less for 11 row of exhausting-gas hole of exhaust part,
So that the piston 1 inside bottle body 1 moves down and pressed home spring 9, and piston 1 move down it is logical
Crossing piston rod 18 pushes the piston 2 19 inside medical fluid adapter cavity 5 to move down, since the flow direction of check valve 26 is piston 2 19
Bottom to the top of piston 2 19, the flow direction of check valve 1 is inside drug storage chamber 2 to inside medical fluid adapter cavity 5 so that
Medical fluid inside 2 19 lower section medical fluid adapter cavity 5 of piston enters the medical fluid adapter cavity 5 of 2 19 top of piston by inlet tube 2 20
Inside, when user stops blowing, under the active force of reset spring 9, reset spring 9 pushes piston 1 to move up, will
Gas in one 10 top bottle body 1 of piston goes out to be discharged from gas vent, at the same by piston rod 18 with piston 2 19 to moving up
Dynamic, when piston 2 19 moves up, the medical fluid inside liquid storage chamber 2 will enter piston two by hose 3 and inlet tube 1
It inside 19 lower section medical fluid adapter cavities 5, is supplemented, while the medical fluid inside liquid storage chamber 2 is being entered into medical fluid below piston 2 19
While 5 inside of adapter cavity, since the flow direction of check valve 3 12 is U-tube 7 to spraying ball 14, recipe on piston 2 19 can be made
Medical fluid inside liquid adapter cavity 5 imports outlet tube 13 from U-tube 7 and sprays misty medical fluid from spraying ball 14, and at this moment human body is just
Air-breathing can suck misty medical fluid in nasal cavity, and when human body is blown again, nasal cavity stops suction, identical as above-mentioned principle, at this
In whole process, gas is discharged in nasal cavity air-breathing mouth, prevents user's habituation from exhaling by nasal cavity air-breathing, by nasal cavity medicine
Object discharge causes to waste and be not achieved good therapeutic effect, and more using the mouth discharge more sucking gases of gas
With the successional characteristic of breathing, gas is discharged in mouth and provides the power of compression for the present invention, when stopping exhaling, compression is moved
Power release atomized medicine is sprayed, can along with human body air-breathing by atomized medicine suck nasal cavity in, while drug discharge with amount with
Mouth discharge gas flow is proportional, is voluntarily controlled by user, and user can make rotating disk 112 rotate by pushing block 113, into
And adjusting the fan-shaped outlet of rotating disk 112 portion 111 and 117 fan-shaped pylone of baffle, 118 degree of engagement, i.e. degree of engagement is big, gas vent more than 111
So that the resistance when rising of piston 1 reduces, the rate of climb is accelerated, therefore 19 degree of the speed of piston two is caused also to be accelerated, so that row
The speed of atomized medicine is accelerated out, to adjust the speed of atomized medicine discharge, adapts to different crowds and uses.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen in scope of the presently claimed invention.
