Abstract
The invention discloses a kind of backpack masks, it includes：Filter screen, elastic band, oronasal mask, exhaust check valve, breather check valve, air communication pipe, it is mainly characterized by being connected to air communication pipe between oronasal mask and filter screen, filter screen weight is carried by other positions in addition to face of human body, to well solve the problems such as existing mask exhaust gas replacement rate is low, filtering tolerance is limited, hot gas and sweat are easy the filter screen to soak, filter screen blocks sight and face's burden is too heavy.
Description
Technical field
The present invention relates to a kind of masks, and air communication Guan Lian is used between oronasal mask and filter screen more particularly to one kind
Logical, by human body, other positions carry the backpack mask of filter screen weight in addition to face.
Background technology
Tiny particles content in air is well-known to the harm of human body.Its serious defense function for destroying human normal,
Cause a variety of diseases of lung, is the whole mankind all in the problem researched and solved.
For common anti-dust mask there is many problems, being summed up mainly has following several sides in our daily lifes
Face：First, exhaust gas replacement rate is low, second is that filtering tolerance is limited, third, hot gas and sweat are easy filter screen to soak, fourth, filtering
Net blocks sight, fifth, face's burden is too heavy.
There is any method to solveWe have made following discussion.
Invention content
The present invention relates to a kind of masks, and air communication Guan Lian is used between oronasal mask and filter screen more particularly to one kind
Logical, by human body, other positions carry the backpack mask of filter screen weight in addition to face.
The above-mentioned technical problem of the present invention is solved by providing a kind of such as backpack mask of lower structure, this is born
Formula mask includes：Filter screen, elastic band, oronasal mask, exhaust check valve, breather check valve, air communication pipe, it is characterised in that：
It is connected to air communication pipe between oronasal mask and filter screen, filter screen weight is carried by other positions of human body in addition to face.
Backpack mask of the present invention has the following advantages that compared with the existing mask in market：
First, exhaust gas replacement rate is high.If the area of filter net of existing mask is too small, the micropore for crossing air filtering is few, can cause clear
For new air for unsaturated vapor, it is not all right that people, which are chronically at anaerobic condition,；If area of filter net is big, the cavity of mouth and nose front end
Greatly, the exhaust gas of exhalation is admixed in this big cavity every time, and exhaust gas replacement rate is again low.It can without best circumstance between the two
It adjusts, can only gather together use.So people are always unwilling to wear masks.Mask of the backpack mask of the present invention an entirety
It has been divided into two independent parts of filter screen and oronasal mask, then, oronasal mask can be made very small, and keep the space before mouth and nose most
Measure small, exhaust check valve can almost drain exhaust gas, to improve exhaust gas replacement rate.
Second is that filter screen good permeability.The filter screen of existing mask, which seems, to be all blinded by entire face, in fact big portion
Facet product is all tightly attached on the face, filtration is not had at all, so causing people for a long time for hypoxgia.Backpack mouthful of the present invention
Cover filter screen is not design in face, and area can be made especially big, allows enough micro porous filtration air, not only meet oxygen supply but also
Realize light air-breathing.
Third, filter screen is convenient to clean.Although existing mask has minority to be mounted with drain tap, human body mouth on guard
The hot gas of middle exhalation quickly can moisten filter screen, and dust is easy to blockage of the micro orifice to lead to inspiratory dyspnea.Backpack of the present invention
It is connected to by an air communication pipe between the oronasal mask of mask and filter screen, breather check valve is also mounted therebetween, breathed out
How hot gas is not stained with filter screen yet.Even if filter screen dust is more, cleaned out even if gently patting.
Fourth, filter screen does not block sight.The area of filter net of existing mask is all larger, slightly puts on a little or does not strangle
Tightly just block sight.The oronasal mask of backpack mask of the present invention is made very small, to block sight.
Fifth, face is light.It is to be assembled in one after oronasal mask and filter screen are fabricated separately to have only a few in existing mask
It is a on the whole.This design in addition to limit by space cannot filter screen it is sufficiently large other than, and a major issue is
Total weight is superfluous heavy, and face's heavy burden of long periods of wear people is very big.The filter screen of backpack mask of the present invention with oronasal mask due to separating
After setting, the weight of filter screen can be undertaken by the back side of head of people, the crown and waist, to ensure that face is light.
Description of the drawings
Embodiments of the present invention are described below with reference to accompanying drawings.
Fig. 1 is that backpack mask of the present invention implements structural schematic diagram.
In figure：1-filter screen, 2-elastic bands, 3-oronasal masks, 4-exhaust check valves, 5-breather check valves, 6-is empty
Gas communicating pipe.
Specific implementation mode
Fig. 1 shows the specific implementation mode of backpack mask of the present invention.Connected by air between filter screen 1 and oronasal mask 3
Siphunculus 6 is connected to, and has been arranged between breather check valve 5.The front end of oronasal mask 3 is provided with exhaust check valve 4.Elastic band 2 only shows
Meaning fastens oronasal mask 3, filter screen 1.
In actual fabrication：The cavity of oronasal mask 3 is made the smaller the better, and material of breathing freely preferably is selected to make, in case water steams
Airsetting knot；The volume of filter screen 1 is done greatly as far as possible to mitigate inspiratory resistance；Filter screen 1 is fixed on the back side of head or the crown is the most square
Just, it is considered further that when if head being disliked to bear a heavy burden inconvenient and ties up to waist.
In actual use, when people suck air：Small space forms negative pressure at once in oronasal mask 3, and exhaust is single
It is closed to valve 4, breather check valve 5 is opened, and extraneous air easily enters in the mouth of people through filter screen 1, air communication pipe 6；When
When people's exhalation air：Small space forms positive pressure at once in oronasal mask 3, and breather check valve 5 is closed, and exhaust check valve 4 is beaten
It opens, exhaust gas displacement is complete.
Unquestionably, backpack mask of the present invention can also there are many transformation and remodeling, it is not limited to above-mentioned embodiment party
The concrete structure of formula, such as oronasal mask and filter screen structure shape and installation site various transformation.In short, backpack of the present invention
The protection domain of mask should also obviously exchange, substitutes and change to those skilled in the art including those
Shape.
