Description
Technical field
The utility model relates to respiratory protection field, refers in particular to a kind of light nose covering type respirator.
Background technology
Along with the aggravation of mankind's activity, air quality is declining gradually, to such an extent as to has influence on the mankind's health, and various protective respirators also arise at the historic moment.What current protection was best is breathing mask class, but it is both clumsy, breathes difficulty again, be not suitable for popular routine use, and the protection effect of common mouth mask class is very difficult satisfactory.
Summary of the invention
It is both convenient that the purpose of this utility model is just to provide one, and protection effect is good again, and breathes respiratory protection utensil smoothly.
The utility model is by sealed breathing body (1), air filtration body (2) and be coated on its outer composition such as outer cover (3) and fixed band (4), breather pipe (5) and a pair of air filtration body (2) communications and liaison are respectively established in sealed breathing body (1) both sides, air filtration body (2) is flat cloth bag structure, cloth sack is sealingly fastened on breather pipe (5) by restraint zone (6), form confined space, air filtration body (2) material is flexible air filter cloth, the cloth bag cavity inside setting of its formation is no less than the thin-wall corrugated tube (7) of, hole gathers on bellows (7) tube wall.
Sealed breathing body (1) can adopt the design of full encirclement nose, also can adopt the design of inserting nostril formula, owing to there being ripe design, therefore be not repeated herein.
Air filtration body (2) adopts flexible air filter cloth processing and fabricating to form, and the bag-shaped structure of cloth allows it have larger air contact area, has improved air filter efficiency.The bag-shaped structure of cloth is easily subsided, so setting is no less than the thin-walled porous ripple pipe (7) of as skeleton, while ensureing that air filtration body (2) bends and pushes in the time of laminating user face, still can normally work.
The utility model does not arrange expiration non-return valve, so that user is more smooth and easy in the time exhaling, this is because air filtration body of the present utility model is enough unobstructed, and non-return valve can bring a small amount of outside foul atmosphere into respirator interior in the time of switch, affects result of use.
The material of outer cover (3) is the cloth that gas permeability is high, and inner side arranges opening, facilitates the replacing of air filtration body.
Fixed band (4) is arranged on outer cover (3) left and right sides end, adopts elastic cord to make.
Brief description of the drawings
Accompanying drawing 1 is structure chart of the present utility model.
Detailed description of the invention
Embodiment: as shown in Figure 1, the utility model is by sealed breathing body (1), air filtration body (2) and be coated on its outer composition such as outer cover (3) and fixed band (4), sealed breathing body (1) adopts full design of surrounding nose, breather pipe (5) and a pair of air filtration body (2) communications and liaison are respectively established in both sides, air filtration body (2) is flat cloth bag structure, cloth sack is sealingly fastened on breather pipe (5) by restraint zone (6), form confined space, air filtration body (2) material is flexible air filter cloth, the cloth bag cavity inside of its formation arranges a thin-wall corrugated tube (7), hole gathers on bellows (7) tube wall.
The material of outer cover (3) is the cloth that gas permeability is high, and inner side arranges opening, facilitates the replacing of air filtration body.
Fixed band (4) is arranged on outer cover (3) left and right sides end, adopts elastic cord to make.
The utility model in use, first closed breathing body (1) is covered on to nose outside, find behind comfortable position, again both sides fixed band (4) is enclosed within on ear, then adjust the position of bellows (7) in air filtration body (2), to ensure comfortable wearing.
If need to change air filtration body (2), first the utility model is taken, remove outer cover (3), then fixed band (4) is loosening, air filtration body (2) is separated with closed breathing body (1), bellows (7) is taken out and puts into new air filtration body (2), more oppositely install.
The utility model is keeping under the prerequisite of profile light and beautiful, has ensured that protection is tight and breathe smooth and easy.
Claims (2)
