Preferably, the nasal cushion 109 is formed with air hole 110.

It preferably, further include upper elastic webbing 401 and lower elastic webbing 402, described upper 401 one end of elastic webbing and eyeshade portion 102 The affixed other end and elastic webbing 4 are affixed, described lower 402 one end of elastic webbing and the affixed other end of first cover portion 101 and elastic webbing 4 It is affixed.

Preferably, the outlet valve 3 includes pedestal 31, inner casing, shell 33 and expiration piece 34, and the inner casing includes upper inner casing 32 and lower inner casing 35, through-hole is formed among the inner casing, and base plate through holes 311, the pedestal are formed among the pedestal 31 31 is affixed with inner casing, and the upper inner casing 32 is formed with inclined-plane 321, and upper 32 lower section of inner casing is affixed with lower inner casing 35, under described It is formed with closing protrusion 351 on the inside of inner casing 35, ventilation protrusion 353, lower 35 shape of inner casing are formed on the outside of the lower inner casing 35 At there is holding tank 352, the holding tank 352 is located between closing protrusion 351 and ventilation protrusion 353, the ventilation protrusion 353 Lower section and the left and right sides are formed with Internal baffle 354, and the lower section and the left and right sides of the ventilation protrusion 353 are formed with interior venthole 355, the inclined-plane 321 and expiration piece 34 are affixed, and the expiration piece 34 is contacted with closing protrusion 351,34 lower section of expiration piece It is formed with arc convex 341 with the left and right sides, the arc convex 341 is located in holding tank 352, and the shell 33 is located at inner casing Outside is simultaneously affixed with inner casing, and 33 lower section of shell and the left and right sides are formed with outer vent 331,33 lower section of shell and a left side Right two sides are formed with outer baffle 332.

Preferably, the interior venthole 355 is set between two neighboring Internal baffle 354, and the outer vent 331 is arranged Between two neighboring outer baffle 332.

Preferably, further include stopping column 36 and bumping post 37, be provided in the base plate through holes 311 and stop column 36, the resistance It blocks column 36 and pedestal 31 is affixed, the pedestal 31 and bumping post 37 are affixed.

Preferably, the expiration piece 34 is made of elastic material.

Concrete operating principle: it in use, mask 1 is put on by face, by 4 sets of elastic webbing on ear, is then pressed with hand Plastic strip 107 and lower plastotype item 108, make the upper bottom profiled of its face, elastic elastic fit side 104 can be bonded and face Portion prevents pernicious gas from entering inside mask 1 from gap.The transverse fold 106 in the second mask portion 103 is to fold Mask material such as when the face of medical worker is longer, pull downward on transverse fold convenient for being applicable in the face of different length Its face of adaptation is straightened in the mask material folded by 106.Vertically folded portion 105 is identical as 106 principle of transverse fold, The medical workers of different forehead width and eye spacing is adapted to by stretching and folding.First cover portion 101 is hard mask, more The first cover portion 101 of hard is easily installed outlet valve 3, while also avoiding first cover portion 101 and be attached at mouth and nose to cause office Damp and hot, initiation medical worker's discomfort in portion.Because nose is located at face center, nasal cushion 109 is prevented convenient for positioning mask 1 Mask 1 is only worn into skew.Air hole 110 is convenient for ventilative and is perspired.Elastic side pad 111 can be silica gel strip, and playing prevents the The water vapor diffusion that the breathing of a bite cover portion 101 generates causes glasses and slide 2 to haze to eyeshade portion 102.

The air breathed out when expiration largely passes through outlet valve 3 and discharges.The working principle of outlet valve 3 is as follows.Such as Fig. 4 Shown, expiration piece 34 is made of smooth flaky elastic material, when expiration piece 34 is that top is fixed on inclined-plane 321, expiration piece 34 lower sections can be along inclined-plane 321 diagonally downward, but protrusion jacks up to the right expiration piece 34 to closing protrusion 351 to the right, makes to exhale Piece 34 is fitted closely in closing protrusion 351, and outlet valve 3 is closed, prevents outside air from entering in first cover portion 101.When When expiration, air-flow and air pressure open expiration piece 34, as shown in figure 5, by the gas of exhalation from interior venthole 355 and outer vent In 331 discharge first cover portions 101, prevent internal humid and slide 2 from hazing.When air-breathing or no breathing, exhale Piece 34 is fitted closely in closing protrusion 351

Wherein, arc convex 341 further prevents contacting external air expiration piece 34 and envelope in the holding tank 352 of U-shaped Close the gap of protrusion 351.Interior venthole 355 and outer vent 331 are downward and two sides openings, are not opened at 33 top of shell Mouthful, it is therefore prevented that exhaled gas breathes out forward pollution reagent, and prevents reagent from splashing in outlet valve 3 from front.Wherein, Internal baffle 354 and outer baffle 332 be staggered, prevent reagent droplet from splashing from interior venthole 355 and outer vent 331 into outlet valve Inside 3.Upper elastic webbing 401 and lower elastic webbing 402 play the effect that the fitting of 1 side of mask is fixed.Stopping column 36 can be ten Font prevents nasal contact expiration piece 34.Bumping post 37 prevents from being drawn inwardly to expiration piece 34 when air-breathing.

The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation Example, all ranges that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
