Description
Technical field
The utility model is related to a kind of masks, belong to articles for daily use technical field.
Background technology
Mask refer generally to be worn over nose and mouth for filter pass in and out the air of mouth and nose, to reach the gas of blocking harmful, gas
The apparatus of taste, spittle disengaging wearer's mouth and nose, is mostly made with cloth or paper etc..Mask can be divided into air filtering type mask and Gas feeding
Mask, in the world at first using mask be China.The outer layer of mask often gathers dust in many outside airs, bacterium
Dirts are waited, usually best several masks of prepare more, to be replaced, should changed clothes daily primary.Air filtering type mask also referred to as
For filter-type respirator, operation principle is that the air containing nuisance is made to be sucked again by people after passing through the media filtration evolution of mask.
Filter-type respirator is a most popular major class in our routine works, the choosing of such mask described in detail below
Selection method and use condition.The structure of one filter-type respirator should be divided into two large divisions, first, the main body of mask, we can letter
Singly be interpreted as it be a mask shelf；The other is filter material part, including being used for dust-proof filter cotton and gas defence
Chemical filtering box etc..So the selection for filter-type respirator uses, some products for producing wide family provide following to you
Convenient, i.e., you can use same mask bodies, when needing dust-proof in dust work environment, mix corresponding mistake
Filter pulp forms anti-dust mask.Though existing mask wide variety exist because wear face structure and shielded area it is of different sizes,
The relative position of mask and facial mouth and nose can not be effectively adjusted, the problem of so as to make mask flexibility difference and not good enough dust-proof effect.
Invention content
Though the utility model is to solve existing mask wide variety but exist because wearing face structure and shielding surface
Product is of different sizes, can not effectively adjust the relative position of mask and facial mouth and nose, so as to make mask flexibility difference and dust-proof effect
It is not good enough, while also there are problems that exhaled air flow is difficult to quickly discharge, and then provide a kind of multi-angle rotation inside mask
Anti-dust mask.

With connecting sewing, every connecting rope is detachably connected on connecting sewing on its corresponding buckle by cotton rope；
The outlet valve includes bottom cover, cover and elastomeric pad, is detachably connected between the bottom cover and cover and the two
Between be formed with venting cavity, elastomeric pad is arranged in venting cavity and it is moved back and forth along the airflow direction in venting cavity.
The utility model has the following effects that compared with prior art：
1st, this product scientific structure design and operation is flexible, according to different human facial structures difference, by two buckles with
It is effectively adjusted between two connecting ropes, timely and effective two connecting ropes can be controlled to be fixed on by the rotational angle of buckle
The position of head part, it is ensured that support housing is fixed on the optimum position of different faces, when enhancing different people wears this product
Comfort, convenient for more smoothly taking a breath.
2nd, the structure setting of outlet valve is more scientific and reasonable in this product, passes through phase between bottom cover, cover and elastomeric pad
Mutually the effect of unidirectional outlet is effectively realized in cooperation, by the mobile realization of elastomeric pad by the inside of support housing to outside air
Between unidirectional exhalation process, it is ensured that support housing inner air from pollution, effectively promoted this product to outside air every
From effect.
3rd, support housing and outlet valve match the cyclic process for effectively realizing air-breathing and expiration in this product, not only ensure
User's air-breathing is smooth, while also is able to realize quick exhalation process by outlet valve, and exhalation process is smoothed out being convenient for
The breathing process of cooperation support housing is smoothed out, and oxygen-enriched accumulation in shell easy to support is effectively improved changing for anti-dust mask
Compression ring border enhances the comfort of scavenging period during use.
