Abstract
The utility model discloses a dustproof mask, relating to a protection supply for human body, especially relating to an improvement of a mask structure. The mask structure comprises a mask body, one partition plate whose center is provided with a one-way air valve is arranged in the mask body, the exterior of the partition plate is in curve shape in order that the partition plate corresponds to the curve of human face, and the two end parts of the partition plate are provided with fixing bolt structures. The partition plate can be made of plastic, and the one-way air valve and the bolt can be produced integrally with the partition plate. The utility model can make the mask naturally divided into an upper space and a lower space, the partition plate is provided with between nose lips. When nostrils breathe, air enters in the upper space of the mask body via the one-way air valve, when the nostrils breathes out air, the air is discharged from the mask body on the upper part. The structure makes the air charge and discharge of the mask body mutually separated, and consequently the air charge part is kept dry, which effectively prevents dust or eyewinker from being absorbed on the mask body as the air is breathed inside and assures the smoothness of the application of the mask body.
Description
Technical field
The utility model relates to a kind of improvement to human body protective articles, particularly Respirator structure.
Background technology
Before the utility model was realized, people got used to using mouth mask as a kind of preventive means to air foreign matter or peculiar smell.But the structure of the protective articles that these often use is unreasonable, and structure is too simple, in use can not reach desirable protection purpose.Such as, people's face since the existence of the bridge of the nose and uneven, when wearing masks, bridge of the nose both sides can't be sealed, protection effect is bad.Particularly the moisture of oral cavity exhalation makes the surface wettability of mouth mask, and the foreign matter in the absorbed air is unhygienic easily; In the heavier place of dust, be easy to stop up the air duct on the mouth mask, the user is had difficulty in breathing.The problems referred to above have all reduced the barrier propterty and the service life of mouth mask.
Technology contents
The purpose of this utility model is: by a kind of anti-dust respirator is provided, the structure of mouth mask is divided into naturally exhales, inhale two spaces, and then solved the problem that exists in the above-mentioned background technology.
Comprise a cover body in the structure of the present utility model, in described cover body, be provided with the dividing plate that central authorities are provided with Non-return air valve.
The outside curved shape of described dividing plate, with corresponding with human face's curve, both ends are provided with the set bolt structure.Described dividing plate can be made by plastics, and described Non-return air valve, screw rod can be integrally manufactured with dividing plate.
The position that described cover body contacts with human body face is provided with cavernous body, so that the contact-making surface of people's face and cover body is sealed.
In use, described dividing plate directly can be inserted in the cover body, pass the sidepiece of cover body with the screw rod in the bolt arrangement, and externally dividing plate is fixed in the cover body with nut.
Said structure of the present utility model can make mouth mask be divided into upper and lower two spaces naturally, and dividing plate is arranged between the muffle, and when air-breathing, air enters in the cover body upper space by Non-return air valve in the nostril, and during breath, gas is discharged from the cover body on top.Said structure makes the air inlet of cover body separate with exhaust phase, thereby makes induction part remain drying, has prevented that effectively dust or foreign matter are adsorbed on along with the suction of gas on the cover body, and it is unimpeded to guarantee that cover body uses.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: cover body 1, cavernous body 2, plastic septum 3, the dividing plate outside 4, Non-return air valve 5, bolt arrangement 6.
Embodiment
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is specified:
Embodiment
As shown in drawings, cover body 1 and stay cord connect in a usual manner.The outside 4 curves of plastic septum 3 are corresponding with human face's curve, and the centre is provided with the Non-return air valve 5 that can upwardly open, and both ends are provided with the standing screw in the bolt arrangement.Described dividing plate, Non-return air valve, screw rod are integrally manufactured.
The position that described cover body contacts with human body face is provided with cavernous body 2, so that the contact-making surface of people's face and cover body is sealed.
In use, described dividing plate directly can be inserted in the cover body, screw rod be passed the sidepiece of cover body, and externally dividing plate is fixed in the cover body with nut.
Said structure of the present utility model can make mouth mask be divided into upper and lower two spaces naturally, and dividing plate is arranged between the muffle, and when air-breathing, air enters in the cover body upper space by Non-return air valve in the nostril, and during breath, gas is discharged from the cover body on top.
