Abstract
The purpose of this utility model is to provide one and stops that pm2.5 particle is effective, it is simple, easy to use to produce, and to the haze nasal obstruction that human body has no side effect.Haze nasal obstruction is connected to form by arc-shaped connecting rod by two nasal obstructions, the nasal obstruction part of haze nasal obstruction is hollow through, the link of its open lower end is with the inhale filter cover of outlet valve, inhale filter cover is directly made up of the Web materials of anti-pm2.5 particle, structure is hollow lower end indent cylinder, cylinder upper end is directly connected with the hollow pass through openings lower end of nasal obstruction, outlet valve is positioned at the groove inner top of inhale filter cover, be connected with groove inner top opening by an axis, axis is with two semi-circular blades, two semi-circular blades when exhaling centered by axis outside doubling open, inwardly divide during air-breathing and form a full circle vanes close groove inner top opening.
Description
Technical field
The utility model relates to human body respiration air filter, specifically a kind of haze nasal obstruction.
Background technology
A large amount of fine particle is discharged in the economy of high density population and social activities, once discharge exceedes atmospheric air circulation ability and carrying degree, fine particle concentration, by continued accumulation, if now affected by quiet steady weather etc., very easily occurs wide range of haze.Have report display, in 500 cities of Largest In China, only reach the air quality standard of world health organisation recommendations less than the city of 1%, meanwhile, polluting 10 the most serious cities in the world has 7 in China.So country quite payes attention to for the improvement of haze, and this is brought into the top priority of China to environmental improvement, but that this governance process can be suitable is very long.From haze individual protector, at present, individual's haze safety device is use common mouth mask substantially, the particle of this type of mouth mask to PM2.5 does not have barrier effect, and really there is the N95 medical mask that haze protective action is, the feature of this mouth mask is as disposable article, price is higher, and should not wear for a long time, according to German labour insurance regulations, workman wears N95 mouth mask at every turn can not exceed half an hour, more than mouth mask eupnea half an hour must be taken after half an hour, otherwise permanent damage may be caused to respiratory system, child old man and have the patient of angiocardiopathy to use.
Technical scheme
The purpose of this utility model is to provide one and stops that pm2.5 particle is effective, produce simple, easy to use, low price, and to the haze nasal obstruction that human body has no side effect.
The technical solution of the utility model is: a kind of haze connected to form by two nasal obstructions 1 is had a stuffy nose, connected by arc-shaped connecting rod 9 between two nasal obstructions 1, the nasal obstruction 1 of haze nasal obstruction is hollow through, and hollow pass through openings 2 lower end of nasal obstruction 1 links the inhale filter cover 3 with outlet valve 4.
The inhale filter cover 3 of haze nasal obstruction, directly be made up of the Web materials of anti-pm2.5 particle, structure is hollow lower end indent cylinder, and the upper end open 5 of inhale filter cover 3 directly closes with the hollow through lower ending opening 2 of nasal obstruction 1, and keeps the air of nasal obstruction 1 through.
Haze nasal obstruction outlet valve 4 be positioned at inhale filter cover 3 groove inner top, be connected with groove inner top opening 7 by an axis 6, axis is with two semi-circular blades 8 of symmetry.
The beneficial effects of the utility model are that compact is easy to carry, and are applicable to going out to wear, and meanwhile, make and sell cheap, are applicable to ordinary consumer, have no side effect, and are suitable for crowd wide.
