Description

The portable air-purifying device

The utility model relates to a kind of portable air-purifying device that uses in the nostril that is placed on.

The air cleaning unit overwhelming majority in the market can not carry use, as air-conditioner, tail gas filter for vehicle etc., has only mouth mask can carry use.Mouth mask is made by gauze, nonwoven, sponge, and detention dust, bacterium play the effect that purifies air when air sees through.But the mouth mask area is bigger, covers in mouth and nose during use, easily produces the sense of feeling oppressed, and is not easy to speech, influences facial appearance, and use is restricted.

The purpose of this utility model provides a kind of air cleaning unit that uses in the nostril that is placed on, and its volume is little, built-in, need not hide mouth and nose, does not influence facial appearance.

The purpose of this utility model is achieved in that with materials processings such as sanitary rubber or paper and becomes one the conulite shell of two mouths is up and down arranged. its size shape is corresponding with the vestibulum nasi size shape, cone wall has the arc protuberance, the protuberance degree is corresponding with wing of nose inwall radian, cone suitable for reading with vestibulum nasi after boundary's size corresponding, the cone end opening is corresponding with the prenaris size; In the tube chamber between the cone upper and lower opening, fixedly filtering material such as nonwoven, sponge is full of the tube chamber cross section, guarantees must pass through filtering material from the air that enters flatly, could go out from another mouthful; Cone end opening outer rim has the thickening circle, and when purifier was placed in the nostril, thickening enclosed the fixed support effect, makes purifier be difficult for coming off from the nostril.

In the above-mentioned air cleaning unit. the height between the cone upper and lower opening be preferably in 7-12 in the least between; The wall of conulite will approach, preferably less than 1.0 millimeters, to guarantee to exceed the diameter that influences tube chamber.The fixed form of filtering material can be used the packing ring squash type, during shell, directly extrudes two ring washers that are parallel to upper and lower opening in processing on inwall, and filtering material is clipped in the middle of the packing ring; Also can extrude two netted partitions that are parallel to upper and lower opening, in the middle of filtering material is clipped in.Filtering material is overlapping placement from level to level, except nonwoven, sponge, also can adopt similar materials such as crocus cloth, activated carbon fiber.

The utility model volume is small and exquisite, and shape meets the human anatomy characteristics, only need fill in the nostril during use, does not influence facial appearance, does not influence speech; Raw material are easy to get, and consumption is few, and cost is low; Consumes energy does not produce new pollutant component; As disposable use.Health more.

The concrete structure of utility model is provided by following drawings and Examples.

Figure one is the front view according to the portable air-purifying device that the utility model proposes.

Figure two is that figure one is at intranarial profile.

Below in conjunction with the details of figure two detailed descriptions according to the portable air-purifying device that the utility model proposes.

This device comprises that has the conulite shell [1] of two mouths up and down, the size and the shape of its size and shape and vestibulum nasi are corresponding, height between the upper and lower opening is preferably between the 7-12 millimeter, the curved protuberance of cone wall, the protuberance degree and the wing of nose [7] inwall radian is corresponding, cone wall is close on the vestibulum nasi inwall, the thickness of cone wall is preferably less than 1.0 millimeters, the position on boundary [3] and size are corresponding behind [2] suitable for reading of cone and the vestibulum nasi, end opening [8] is corresponding with the position and the size of prenaris [10], at cone end opening outward flange thickening circle [9] is arranged; There are two ring washers [5] tube chamber [4] lining in cone, accompanies filtering material [6] in the middle of the packing ring, and filtering material is two-layer nonwoven folder one deck sponge.

Air at first passes through prenaris [10] and cone end opening [8] along direction shown in the arrow, passes through filtering material [6] then, enters the nasal cavity depths by cone [2] suitable for reading at last.
