Specific embodiment
Now in conjunction with Detailed description of the invention, the present invention will be further described with embodiment:
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, there are three the filter face mask of breather valve, the filtering mouths for a kind of band
The centre of cover is equipped with for the breather valve A1 for human exhaled breath, and the two sides of the breather valve A1 are respectively provided with for human body air-breathing
Breather valve B2.
The breather valve A includes domed valve block A11 and breather valve A pedestal 12.The valve block A11 is incorporated in described exhale
Inhale the top of valve A pedestal 12.The valve block A11 includes circular egative film A111, is extended outward to form by the edge egative film A111
Edge piece 112 in a ring, the support rod A113 being downwardly extending by the bottom end egative film A111 center and it is set to support rod
Limited block A114 on A113.The thickness of the egative film A111 is greater than the thickness of edge piece 112.The thickness of the edge piece 112
It is set as 0.05 millimeter to 0.2 millimeter.
The valve block A11 is made of software silica gel, when being combined with the breather valve A pedestal 12, the support rod
The through hole A121, the limited block A114 that A113 is inserted into 12 center of breather valve A pedestal are stuck in the through hole A121's
Bottom end.
The breather valve B2 includes valve block B21 and breather valve B pedestal 22.The valve block B21 is incorporated in the bottom the breather valve B
The bottom end of seat 22.The support that the valve block B21 includes circular egative film B211, is downwardly extending by the bottom end egative film B211 center
The bar B212 and conical limit block B213 on support rod B212.
The valve block B21 is made of software silica gel, when being combined with the breather valve B pedestal 22, the support rod
B212 is inserted into 22 center of breather valve B pedestal
Through hole B221, the conical limit block B213 are stuck in the top of the through hole B221.
The breather valve B2 detachable connection has rounded filter mechanism 3.The filter mechanism 3 includes cotton cover 31
With breather valve engaging section 32.Cotton-wool, polyethylene fibre silk, polypropylene filaments, polyvinyl chloride are filled in the cotton cover 31
At least one of fiber filament and styroflex silk.The breather valve engaging section 32 is set to 31 bottom end of the cotton cover center
And it is intermeshed with the breather valve B pedestal 22.
The filter face mask further includes hard inner cover 4 and the soft outer cover 5 for wrapping up hard inner cover 4.The breather valve A pedestal 12 and two
A breather valve B pedestal 22 is set on the hard inner cover 4.The breather valve A pedestal 12 is set to the centre of the hard inner cover 4, institute
State the two sides that breather valve B pedestal 22 is respectively arranged on breather valve A pedestal 12.
At the opposite position of breather valve A pedestal 12 and two breather valve B pedestals 22, the soft outer cover 5 is equipped with and opens
A51 and two opening B52 of mouth.
Working principle of the utility model is: two breather valve B2 are for supplying in use, breather valve A1 is used for for human exhaled breath
Human body air-breathing.
For breather valve A1, valve block A11 is incorporated in the top of breather valve A pedestal 12.Since the arch of valve block A11 is set
Meter, when exhaling, the positive pressure of discharge gas easily blows the frivolous edge piece 112 of valve block A11 open, rapidly to arrange internal exhaust gas
It removes；And negative pressure when air-breathing can make the edge piece 112 of valve block A11 inwardly tightly be bonded breather valve A pedestal 12, make between both
Any gap will not be stayed, to avoid the pollutant of inspiration external environment.
For breather valve B2, valve block B21 is incorporated in the bottom end of the breather valve B pedestal 22.It is flat due to valve block B21
Shape design, when exhaling, the positive pressure of discharge gas can make the egative film B211 of valve block B21 tightly be bonded breather valve B pedestal 22, rise
To the effect blocked, internal exhaust gas is avoided contaminated filter mechanism 3 to be discharged from breather valve B2；And negative pressure when air-breathing can make valve block
The egative film B211 of B21 inwardly unclamps breather valve B pedestal 22, makes there are gap, to play the work for adjusting air velocity between both
With, make outside air by filter mechanism 3 filtering after from the gap flow into for human body respiration.
In conclusion after those skilled in the art read the utility model file, skill according to the present utility model
Art scheme and technical concept are not necessarily to creative mental labour and make other various corresponding conversion schemes, and it is practical new to belong to this
The range that type is protected.
