Description
Technical field
The utility model belongs to daily life protective articles field, is related to a kind of haze filter face mask.
Background technology
With the quickening of city modernization, in city, increasing factory, The Surroundings in Cities pollution are presented
Seriously, often there is serious haze phenomenon in the discharge severe overweight of vehicle exhaust, some local cities, and haze is different from other
Atmosphere pollution, there is serious toxicity and concentration, in order to avoid the serious shadow that atmosphere pollution brings for human lives as far as possible
Ring, it is therefore desirable to it is a kind of can be with the better filter plant of filter effect.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of haze filter face mask.
To reach above-mentioned purpose, the utility model provides following technical scheme：
A kind of haze filter face mask, including mask body, support frame, filter layer, outlet valve and inlet valve, the mask master
Body separates to form suction muffler by support frame and filter layer, and the mask body is provided with pneumostome, and the pneumostome is by exhaling
Inhale passage and atmosphere, the pneumostome are connected by inlet valve with suction muffler, the outlet valve is arranged on exhalation passages
Rear end.
Further, in cone, the section of passage is gradually reduced the exhalation passages from inside to outside.
Further, the inlet valve is arranged on the side of respiration channel.
Further, the inlet valve is arranged on mask body.
Further, it is additionally provided with gauze layer in the respiration channel.
Further, the filter layer is from inside to outside successively by electro static filtering film, electrospun fibres layer, NACF
Layer, nonwoven layer are formed.
The beneficial effects of the utility model are：The present apparatus, exhales and the passage of outlet is separated, and by mask with
Filter layer is arranged to two layers point and opened, and for the protection effect of haze, can effectively prevent the blocking at filter layer, and compared to
Other mouth masks, there is bigger filter area, make breathing more unobstructed, filter effect is more preferable.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing illustrates：
Fig. 1 is the structural representation of the first embodiment of the utility model；
Fig. 2 is the structural representation of second of embodiment of the utility model；
Fig. 3 is Fig. 1 left view；
Fig. 4 is Fig. 2 left view.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
A kind of haze filter face mask of the utility model, including mask body 1, support frame 2, filter layer 3, outlet valve 4 and suction
Air valve 5, mask body 1 separate to form suction muffler 6 by support frame 2 and filter layer 3, and mask body 1 is provided with pneumostome, breathing
Mouth is connected by respiration channel 9 and atmosphere, pneumostome by inlet valve 5 with suction muffler 6, and the outlet valve 4, which is arranged on, exhales
The rear end of gas passage 9, upon inhalation, the pressure in mask body 1 reduce, and outlet valve 4 is closed after being under pressure, and inlet valve 5 is beaten
To open, extraneous air is filtered by filter layer 3, then by reaching the oral cavity of human body after inlet valve 5 by pneumostome.
During expiration, human oral cavity is exhaled, and the pressure increase in mask body 1, outlet valve 4 is opened after being under pressure, air-breathing
Valve 5 is closed, and the waste gas of characteristics of contaminated respiratory droplets is directly discharged outside air from outlet valve 4.
If Fig. 1 and Fig. 3 is the utility model the first embodiment, wherein 8 be earclip, the present embodiment is by the inlet valve 5
The side of respiration channel is arranged on, respiration channel is made of the tubular material of taper, and the section of passage is gradually contracted from inside to outside
It is small, can either be absorbed with effective admission waste gas in mouth mask or, respiration channel, Ke Yiyou are all passed through in the present embodiment expiration air inlet
Effect ground mitigates difficulty of the people when putting on mouth mask mouth breathing, and gauze layer 9 is arranged in respiration channel, can further avoid outer
The impurity on boundary enters in respiration channel.Filter layer is from inside to outside successively by electro static filtering film, electrospun fibres layer, active carbon fibre
Tie up layer, nonwoven layer is formed.
If Fig. 2 and Fig. 4 is second of embodiment of the utility model, wherein 8 be earclip, the present embodiment sets inlet valve 5
On mask body, by mouth mask implement tidal air when pressure change, make the triggering of outlet valve 4 and inlet valve 5 cleverer
It is quick, make filter layer more efficient, and the area of bigger filter layer can be increased.Filter layer from inside to outside successively by electro static filtering film,
Electrospun fibres layer, activated carbon fiber layers, nonwoven layer are formed.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The scope of restriction.
