Description
Technical field
The present invention relates to a kind of gas filtration with double cavity structure and switch, it is adaptable to gas is filtered and
The occasion of exchange, such as mouth mask, breathing mask device, solve it in exchange process, and gas exchange is poor, and sensation of asphyxia is strong to ask
Topic.
Background technology
Society also brings some environmental problems, the such as pollution of air while developing rapidly.People are increasingly recognizing
While knowing the health that air pollution gives people and bring harm, but rarely have means to be overcome.At present, people are in haze etc.
When atrocious weather is gone on a journey, typically can all take and put on the safeguard procedures such as mouth mask.Similar products on the market are also a lot, principle
Broadly similar, i.e., make foul atmosphere pass through filter layer in mouth mask when by air-breathing, filters out harmful substance therein, such as PM2.5
Deng.But because the volume of these harmful substances is very little, so needing filter screen density sufficiently large, filtration is not otherwise had at all
Effect.Increasing filter screen density can bring a direct problem, just be so that breathing becomes difficult, and sensation of asphyxia is strong.So
General requirement wears masks the time should not be long, otherwise will bring adverse effect to body.Product earlier, exhalation and suction
Gas will be strong through filter screen, sensation of asphyxia.In some nearest products, one-way valve designs are employed in exhalation process,
During expiration, check valve is opened, and the gas of exhalation can be discharged directly by check valve, and be no longer pass through filter screen；During air-breathing, check valve
Closure, the air outside mouth mask enters respiratory tract by filter screen under negative pressure.Advantage of this is that exhalation process becomes smooth, but
There is no any impact on breathing process, particularly in the case where filter screen is dense, sensation of asphyxia is still present.Cause sensation of asphyxia
Another reason be, due to the presence of the neighbouring larger space of nasal cavity, the gas for breathing out to be will be filled with during expiration (hereinafter referred to as
" foul smell "), when air-breathing again, the foul smell that these contain high concentration carbon dioxide can be inhaled into respiratory tract again, due to breathing not
To ozone, cause human body respiration difficult.
The content of the invention
For problem above, the present invention proposes a kind of double cavity structure design, can realize that it is same that air filtration is purified
When, gas exchange efficiency is improved, substantially reduce sensation of asphyxia during breathing.
Device inverting chamber (8) side is brought into close contact with face, sealed device (6) nasal cavity be formed about one it is little
Confined space, the confined space is communicated by check valve (9) with outside air, and when exhaling, check valve (9) is opened, and makes foul smell
Discharge；It is clear air cavity (3) for clean air after stored filter to be close to outside inverting chamber, is provided between clear air cavity and ventilation lumen
Check valve (7).Once during complete respiratory movement, the action of two check valves is：During air-breathing, inverting chamber (8) produces negative pressure,
Under suction function, check valve (9) closure (prevents outside dirty air from entering inverting chamber), while check valve (7) is opened, makes clear gas
Clean air enters inverting chamber in chamber, and then enters respiratory system, while making clear air cavity produce certain negative pressure；During expiration,
Under inverting chamber malleation and clear air cavity negative pressure collective effect, check valve (7) rapid closing (prevents foul smell from entering clear air cavity), meanwhile,
Check valve (9) is opened, and makes foul smell discharge inverting chamber rapidly.The outer surface (face with air contact) of clear air cavity is ventilating frame knot
Structure, external application filter screen, to harmful components in air filtering excessively.During air-breathing, due in clear air cavity portion gas be inhaled into inverting chamber and
Respiratory system, makes clear air cavity produce negative pressure, and in the presence of negative pressure, the air of outside enters into clear air cavity by filter screen.Due to
Check valve (7) is closure in exhalation process, and the gas of exhalation can't make negative pressure in clear air cavity weaken or disappear, so this is negative
Pressure may proceed to promote the air of outside to enter clear air cavity by filter screen, until pressure balances each other with outer air pressure in clear air cavity.
In order to improve gas exchange efficiency, the volume of inverting chamber should be smaller as much as possible.So that the foul smell of exhalation to the greatest extent may be used
Discharge inverting chamber more than energy.For convenience foul smell discharge, it is preferable that can by check valve (9) installed in nostril underface.By
Little with the confined space volume that face is formed in inverting chamber, the foul smell volume that inverting chamber is remained in during expiration is also little, so inhales
More clean airs are just had during gas inverting chamber is entered by clear air cavity, and then enter respiratory system, so as to improve respiratory system
The efficiency of air exchange.
The sensation of asphyxia produced in order to reduce breathing process, clear air cavity should be larger as far as possible.Theoretically, clear air cavity
Bigger, the negative pressure therefrom drawn produced by the air of equal volume is less, that is to say, that suck up more laborsaving, and air-breathing will
It is more smooth.Meanwhile, clear air cavity becomes big, can also increase the contact area of clear air cavity and outside air, you can increase the area of filter screen,
The efficiency of gas filtration is improved, is conducive to the filtration of air；On the other hand, due in exhalation process check valve (7) be closure
, if so now also in negative pressure state in clear air cavity, can continue to make outside air pass through filter screen to enter in it,
That is, the duration for crossing air filtering can be whole respiratory.And the process that existing product filters gas can only occur in one
The expiratory phase of individual respiratory cycle.
Further to reduce sensation of asphyxia, it is preferable that clear air cavity support is elastic construction.Upon inhalation, check valve (7) is beaten
Open, clear air cavity shrinks with the wherein reduction of gas；Upon exhalation, check valve (7) is closed, effect of the clear air cavity in elastic force
Lower recovery, during recovery, outside air enters clear air cavity by filter screen, and so on.
In sum, due to adopting double cavity structure, isolating between clean air and exhalation foul smell is realized first, in addition
The design (inverting chamber confined space is little, and clear air cavity is big) of big loculus, it is ensured that foul smell is discharged as far as possible, make one to breathe is exhausted
Major part is clean air in clear air cavity, it is to avoid the foul smell of exhalation is sucked again, head caused by excessive carbon dioxide institute
Dizzy, headache.Secondly, under single-chamber, gas filtration process can only occur in breathing process, and action time is short, and will be such as
The air needed for sucking is completed under conditions of this time is short, particularly in the case of filtering layer densification, air-breathing very expense will be made
Power, and in the present invention because the effect of check valve (7) is closed, when exhaling, check valve (7) is closure, clear air cavity is empty with outside
The filtration exchange process of gas can proceed, such that it is able to greatly prolong the airfiltering time (about doubling) so that
The clean air that clear air cavity has time enough to be inhaled in inverting chamber in swapping with outside air to supplement clear air cavity.
3rd, for general mouth mask, if not leaving too many space near nasal cavity, required air capacity will be in air-breathing during air-breathing
During be accomplished by filtration, particularly filter screen densification in the case of, suck it is very laborious；If left too near nasal cavity
Many spaces, then can cause foul smell to fill, and breathe out the problem that foul smell is again sucked into, and the present invention solves well this problem,
Because inverting chamber is little, so most foul smells are discharged when exhaling, and during air-breathing, most clean airs are from clear gas
Chamber, simultaneously because the volume of clear air cavity is relatively large, it is relatively also less therefrom to obtain the negative pressure produced during a certain amount of gas,
That is, make air-breathing become smooth.So, one aspect of the present invention improves the exchange efficiency of gas, on the other hand causes breathing
Whole process all becomes very smooth, so as to eliminate sensation of asphyxia.
