Description
Technical field
It the utility model is related to a kind of mask, and in particular to a kind of anti-dust mask.
Background technology
Coal industry, metallurgy industry and wood furniture manufacturing working environment dust concentration are big, and workers with long time is this
Operation is easy to suffer from all kinds of breathing problems in the high environment of dust concentration, seriously endangers health.At present, for prevention
The most common method of occupational disease caused by dust is to wear mask, and mask is broadly divided into two classes in the prior art, one kind be only by
Simple mask made of individual layer or several layers of filtering material, this Respirator structure is simple, cheap and easy to get, but dust-proof effect is poor, needs
Often replace；Another kind of is to carry breather valve, this kind of good dustproof effect, but design comparison is complicated, and when wearing, is had a hunch
There is vexed sensation, this is because the carbon dioxide of people's exhalation, it is impossible to rapidly discharge inside mask, and second of inspiration remains in
Two vaporized carbon exhaust gas of mask intracavitary are to intrapulmonary, and this kind of mask is usually mask type protective mask, it includes cover body and filtering
Passage, has frenulum on cover body, filtering material is equipped with filtration channel.Its volume is larger, complicated, and accommodation is narrow.
Utility model content
To solve the above problems, the utility model proposes a kind of anti-dust mask, design is reasonable, simple in structure, dust-proof effect
It is good, happy, small volume is breathed, it is applied widely.
A kind of anti-dust mask, it includes frenulum, mask main body, respiratory cavity and breathing air valve, the respiratory cavity and is arranged at
The middle part of mask main body, and above mask main body, a pair of of tidal air of inside and outside connection is symmetrically arranged with respiratory cavity both sides
Valve installing port；The covering of described breathing air valve one end is provided with one layer of strainer, in installing port, breathing air valve other end suit
There is airscoop shroud, be threadedly coupled between airscoop shroud, and some circular holes are evenly arranged with airscoop shroud, between strainer and airscoop shroud
It is provided with gas-filtering device；The frenulum is fixedly mounted on mask main body both ends.
The respiratory cavity uses silica gel material, soft is contacted with face.
The gas-filtering device is air filtering core.
The gas-filtering device includes filter cotton and activated carbon, and filter cotton is covered on strainer and airscoop shroud,
Activated carbon is filled between filter cotton.
The frenulum extends back through face both sides and is movably connected on the back of head of people.
The respiratory cavity is additionally provided with one-way breather valve, one-way breather valve be can exhale can not air-breathing one-way breather valve,
Correspondence is installed on naris position.
The utility model advantage is that design is reasonable, simple in structure, using the interior breathing Standard Valve Design for setting filtration apparatus, is prevented
Dirt effect is good, and increase has expiratory one-way valve on respiratory cavity, makes one the carbon dioxide of exhalation, can rapidly discharge respiratory cavity
Outside, breathes happy, small volume, applied widely.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model filtration apparatus mechanism map（1）.
Fig. 3 is the utility model filtration apparatus mechanism map（2）.
Embodiment
Referring to the drawings a kind of anti-dust masks of 1-3., it includes frenulum 03, mask main body 01, respiratory cavity 02 and breathing air valve
04, the respiratory cavity 02 is arranged at the middle part of mask main body 01, and positioned at the top of mask main body 01, it is symmetrical in 02 both sides of respiratory cavity
It is provided with a pair of of breathing air valve installing port of inside and outside connection；The covering of 04 one end of the breathing air valve is provided with one layer of strainer 06, pacifies
In installing port, breathing 04 other end of air valve is set with airscoop shroud 07, is threadedly coupled between airscoop shroud 07, and airscoop shroud 07
On be evenly arranged with some circular holes, gas-filtering device 08 is provided between strainer 06 and airscoop shroud 07；The frenulum 03 is solid
Dingan County is mounted in 01 both ends of mask main body.
The respiratory cavity 02 uses silica gel material, soft is contacted with face.
Further preferably, the gas-filtering device 08 is air filtering core.
Further preferably, the gas-filtering device 08 includes filter cotton and activated carbon, and filter cotton is covered in strainer
06 and airscoop shroud 07 on, activated carbon is filled between filter cotton.
The frenulum 03 extends back through face both sides and is movably connected on the back of head of people.
The respiratory cavity 02 is additionally provided with one-way breather valve 05, one-way breather valve 05 be can exhale can not the unidirectional of air-breathing exhale
Air valve, correspondence are installed on naris position.
When the utility model is used, respiratory cavity 02 is covered on above people's mouth and nose, fastens frenulum 03, during air-breathing, extraneous air
Breathing air valve 04 is entered by airscoop shroud 07, after 08 adsorption filtration of filtration apparatus, clean air enters in respiratory cavity 02；Exhale
When, people gives off carbon dioxide partly to have and is discharged at breathing air valve 04, is partly discharged via expiratory one-way valve 05.
The utility model advantage is that design is reasonable, simple in structure, is set using the interior breathing air valve 04 for setting filtration apparatus 08
Meter, good dustproof effect, and increase has expiratory one-way valve 05 on respiratory cavity 02, makes one the carbon dioxide of exhalation, can be rapidly
Discharge outside respiratory cavity 02, breathe happy, small volume, it is applied widely.
