Specific implementation mode
To facilitate the understanding of the present invention, with reference to embodiment to invention is more fully described.Although giving
The preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to described herein
Embodiment.It is made the disclosure of the present invention more thorough and comprehensive on the contrary, purpose of providing these embodiments is.
Referring to Fig. 1, the present invention provides a kind of breathing mask, including mask body 1 and it is connected with the mask body 1
For to the mask body 1 convey gas admission line 2.The mask body 1 includes air inlet 11 and exhaust outlet 12,
The air inlet 11 is connected with the admission line 2.The breathing mask further includes being set to leading in the mask body 1
To pipe 3 and the gas deflation assembly being set in the mask body 1.One end of the guide pipe 3 by the air inlet 11 with
The admission line 2 is connected, and the opening of the other end of the guide pipe 3 is positioned at the top of the air inlet 11.The exhaust
Component includes pressure acquisition unit 41, pressure sensitive unit 42, controller 43, exhaust pipe 44 and is set to the exhaust pipe 44
Interior exhaust modulation device.One end of the pressure acquisition unit 41 connects the outside wall surface of the mask body 1, and the pressure is adopted
The other end of collection unit 41 is connected with the pressure sensitive unit 42.The controller 43 respectively with the pressure sensitive unit
42, exhaust modulation device is connected.The exhaust pipe 44 is connected with the exhaust outlet 12.
Through the continuous positive pressure fresh air in admission line input breathing mask, since the opening of guide pipe is towards respiratory surface
The top of cover, under the guiding of guide pipe so that form top-down circulating current into the air-flow in breathing mask, avoid
The carbon dioxide of exhalation is stranded in the top of breathing mask when user exhales, and the repetition of carbon dioxide is effectively avoided to suck.
Controller receives pressure sensitive unit signal determining user breathing and replaces signal, when the wearer inhales the air, control
Device controls exhaust modulation device and reduces exhaust pipe sectional area, reduces air leakage, while increasing breathing mask internal pressure, auxiliary makes
User sucks live gas；When the wearer exhales the air, controller control exhaust modulation device expands exhaust pipe sectional area, increases leakage
To reduce respiratory surface internal mask pressure breathing mask directly is discharged through gas vent and exhaust pipe in user's exhaled gas by tolerance
Outside.To by the design of exhaust modulation device, on the basis for having used the gas vent than conventional breathing mask aperture bigger
On, the intelligent control to leaving area is realized, has both reduced the waste that power consumption in turn avoids air source gas, while can also be more
Auxiliary user breathing well, is also compatible with the user of matching different tidal volumes.Moreover, the design of exhaust modulation device is led with aforementioned
The design of skirt is combined, and further improves the overall effect of breathing mask.
Referring to Fig. 2, the exhaust modulation device includes the adjustment disk 53 being set in the exhaust pipe 44, with the tune
The connected torsion return unit 52 of full wafer 53, can control the adjustment disk 53 to overcome the torsion of the torsion return unit 52 around described
The motor 51 of the central axis rotation of exhaust pipe 44, and it is set to the adjustment side of the disk 53 far from torsion return unit 52
Fixed wafer 54.The adjustment disk 53 is equipped with hollow area 532 and solid area 531, and the fixed wafer 54 is equipped with sky
Heart district domain 542 and solid area 541.Under off working state, along gas discharge direction, the solid area of the adjustment disk 53
531 partially or completely block the hollow area 542 of the fixed wafer 54,541 part of solid area of the fixed wafer 54
Or the hollow area 532 of the adjustment disk 53 is blocked completely.
When current of electric is 0, under the action of torsion return unit, adjust disk 53 and fixed wafer 54 formed closing or
Partially enclosed barrier sheet prevents gas from being discharged or reduce gas discharge amount.Conversely, under the action of electric current, motor 6, which drives, to be adjusted
Full circle piece 53 overcomes the torsion of torsion return unit 52 to rotate, and forms leakage hole or adjusts the size of leakage hole, electric current is bigger, motor
Torsion is bigger, and leakage hole is bigger.The gas entered through gas vent outside exhaust pipe domestic demand discharge breathing mask is breathed out by user as a result,
Body, practical gas vent are made of adjustment disk fixed wafer, so can realize that row is realized in the rotation that disk is adjusted by control
Go out the control of gas flow.
In the present embodiment, 531 area of solid area of the adjustment disk 53 is identical as 532 area of hollow area, institute
541 area of solid area for stating fixed wafer 54 is identical as 542 area of hollow area, the solid area of the adjustment disk 53
531 is identical as fixed 542 area of hollow area of circle 54, under off working state, along gas discharge direction, and the adjustment
The solid area 531 of disk 53 blocks the hollow area 542 of the fixed wafer 54, the solid area of the fixed wafer 54 completely
The hollow area 532 of the adjustment disk 53 is blocked completely in domain 541.When current of electric is 0, in the effect of torsion return unit
Under, closed barrier sheet can be formed by adjusting disk 53 and fixed wafer 54, and gas is prevented to be discharged.To be formed to greatest extent
Leakage hole, the adjustable range of capacity also bigger.
Specifically, the solid area 531 and 532 number of hollow area of the adjustment disk 53 are 2, and along the exhaust
The central axis of pipe 44 is staggeredly symmetrical, and solid area 531 and 532 number of hollow area of the fixed wafer 54 are 2,
And it is staggeredly symmetrical along the central axis of the exhaust pipe 44.It is right as a result, under the premise of not influencing capacity regulating effect
The electric current output requirement of motor is lower, further reduced power consumption cost.
More specifically, the torsion return unit 52 is torsion resetting spring.
More specifically, the pressure acquisition unit 41 is pressure acquisition pipe.
More specifically, the pressure sensitive unit is pressure sensor.
In the present embodiment, the diameter of the exhaust outlet 12 is identical as the diameter of the exhaust pipe 44, is 5-15mm.By
This, the user that can match different tidal volumes uses, while taking into account cost and power consumption.
The present invention also provides a kind of respiratory assistance apparatus comprising breathing mask as described above.To Respiration assistance
Equipment can realize the intelligence adjusting to capacity, expand the use function of equipment, promote the using effect of user.
More specifically, the respiratory assistance apparatus further includes host, and the host is equipped with processor, and the controller is
Processor.The processor conduct for using due to the collocation of breathing mask and the host of Respiration assistance, therefore host directly being used to be equipped with
The controller of exhaust modulation device not only contributes to save cost, also helps the stability and accuracy of control.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
