Abstract
The utility model relates to a cleaning appliance which can filter air suck by a nose. The utility model is provided with filter media, and a sleeve which is matched with the nose is sheathed on the outside of the filter media, wherein, a sleeve which is matched with nostrils can be a cover sleeve which is preferably a closed cover sleeve, and the opposite two ends of the cover sleeve are provided with venting holes. The outer side of the sleeve is provided with bulge loops or lug bosses. The filter media is fibrous filter media, and is preferably active carbon fiber filter media. The utility model not only can block and filter the dust in the air, but also can effectively adsorb and filter the harmful components such as, so 2, co, hydrocarbons, nitrogen oxide, etc. The utility model can effectively protect the health of the human body.
Description
The utility model relates to a kind of respiratory nasal road carries out filtration, purification to the gas that sucks utensil that is arranged on.
The existing gas that nose is sucked carries out the utensil of filtration, purification, and mouth mask and breathing mask are arranged, and all contains filter medium.But they all are that nose and Zi, one of the lunar mansions are covered, and volume ratio is bigger, influence speaking and shouting and express one's feelings of Zi, one of the lunar mansions, hinder the carrying out of other actions.Mouth mask and the sealing of Zi, one of the lunar mansions face are bad, can not play the effect of filtration to part from the side direction inhaled air, and can only stop filtration to particulate matter.The breathing mask heaviness is not easy to carry.
The purpose of this utility model provides a kind of being easy to carry, and the gas of nose suction is carried out the utensil of filtration, purification.
The gas that the utility model is gone into snuffing carries out the utensil of filtration, purification, still contains filter medium, it is characterized in that: filter medium is with the cover that matches with nose outward.The filter medium that has overcoat has constituted the nasal cavity clarifying filter, can insert the nostril or the nasal cavity of nose easily, and overcoat matches with nostril or nasal cavity.From the gas of nose suction, with regard to necessary filter medium through the nasal cavity clarifying filter, quilt is filtration, purification effectively, and easy to carry like this.The cover that is enclosed within filter medium and matches with nose can be apply arbitrarily (as cover of metallic sheath, duroplasts cover, inorganic solidified thing etc.), also can be soft cover (flexible plastic cover, cloth cover, nonwoven cloth case, rubber and silicon rubber etc.).It promptly can retrain filter medium, contacts with nose again and is arranged on the respiratory tract of nose.With the cover that nose matches, be that cover will have the part that matches with nostril or nasal cavity, so that insert nostril or nasal cavity.Can partly insert nostril or nasal cavity, another part also can all insert in nostril or the nasal cavity outside nostril or nasal cavity.The part of inserting in the nose contacts with nostril or nasal cavity, makes the nasal cavity clarifying filter remain on the breathing runner of nose, makes the gas of the suction of nose flow through the fillter section that is full of filter medium.Cover can be a ring set, also can be jacket casing, can also be barrel-shaped cover, and barrel-shaped cover has passage.The cover that matches with nose is the enclosure preferably.The enclosure can be the ventilative enclosure, also can be the enclosure of sealing, and the relative two ends of the sealing enclosure have passage.The enclosure can cover the not loose outflow of filter medium effectively, and prevents the damage to filter medium.The enclosure of the cryptomere that the enclosure preferably connects.Seal better with nostril or nasal cavity for the outside that makes cover and to cooperate, and make cover and nose keep stable state, the outside of cover has bulge loop or boss.Filter medium can be fiber filter media for all gases filter medium.Filter medium is preferably the activated carbon fibre filtering medium, not only can filtration of particulate matters, can also filter absorption harmful gas and steam.The activated carbon fibre filtering medium is preferably to arrange piles up activated carbon fiber.
So, the utility model compared with the prior art, it is little to have a volume, carries easily and uses; Only insert nostril or nasal cavity, Zi, one of the lunar mansions and other positions are not produced obstruction and influence; Can the gas of all nasal passage of flowing through be filtered, and can also carry out adsorption filtration pernicious gas and steam; Simple in structure various, make processing easily, also be convenient to the replacing of filter medium.
Accompanying drawing has been represented the nasal cavity clarifying filter schematic diagram of a kind of capsule set of the utility model.Wherein, Fig. 1 is the nasal cavity clarifying filter master cutaway view of capsule set, and Fig. 2 is the nasal cavity clarifying filter schematic appearance of capsule set.Example below in conjunction with accompanying drawing further specifies the utility model.
The nasal cavity clarifying filter (seeing accompanying drawing) of this capsule set contains filter medium 3, and filter medium is the fine activated carbon fiber of polypropylene.The activated carbon fibre filtering medium is with the silicon capsule enclosure 1,2 that matches with the nostril outward.Just the cover that matches with the nostril is two barrel-shaped enclosures that connect 1,2.After the enclosure butt joint, be enclosed in the enclosure, form the nasal cavity clarifying filter of capsule set arranging the activated carbon fiber of piling up.The two ends that the enclosure is relative have passage.The outside of the epimere enclosure has three road bulge loops.Three road bulge loops have good elasticity, and in the nostril tight fit inside.During use, the nasal cavity clarifying filter of capsule set is inserted the nostril, the silicon capsule enclosure outside particularly contacts in three road bulge loops and the nostril, and the generation resistance remains in nostril and the nasal cavity nasal cavity clarifying filter of capsule set.When with nose when air-breathing, the gas of suction is all through the passage of lower end, and the activated carbon fibre filtering of piling up in the enclosure of flowing through, and flows into nasal cavity and respiratory system from upper vent hole again.The nasal cavity clarifying filter of capsule set not only stops and filtered airborne dust, but also effectively adsorption filtration harmful components such as carbon monoxide, hydro carbons, sulfur dioxide, nitrogen oxide, purified inhaled air, protected the health of human body.
