Abstract
The utility model discloses an air purifying device. The air purifying device comprises a U-shaped connecting part and two air purifying parts, two ends of the U-shaped connecting part are firmly connected with the two air purifying parts, each air purifying part comprises a filter membrane, and the filter membrane is 2 to 3 millimeters in thickness. The air purifying device is simple and reasonable and can be placed in the nasal cavity of human body for purifying the air which enters the nasal cavity. The filter membrane is a nano-fiber membrane, the filter membrane is capable of filtering out fine dust with grain diameter of 0.25 micrometers, and therefore, the air filtering and purifying effect is better.
Description
Technical field
The utility model relates to a kind of air cleaning unit.
Background technology
Development along with urban industry; urban air pollution is day by day serious; the weather that often there will be some to be similar to haze, so contain a large amount of harmful fine particle or dusts in air, therefore a kind ofly can put into nasal cavity to play the exploitation of device of purification filtering air necessary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device that can put into nasal cavity and can play purification filtering air.
For addressing the above problem, the technical scheme that the utility model adopts is:
An air cleaning unit, comprises U-shaped connecting portion and two air cleaning portions, and two end points of described U-shaped connecting portion are fixedly connected with two air cleaning portions respectively, and described air cleaning portion comprises filter membrane, and the thickness of described filter membrane is 2 ~ 3mm.
As preferably, described filter membrane is nanofiber filter membrane.
As preferably, described filter membrane is cylindrical.
As preferably, the aperture of described filter membrane is 0.25um.
As preferably, described air cleaning portion also comprises the annular rubber ring that is arranged on filter membrane sidewall surfaces, and described annular rubber ring is fixedly connected with filter membrane.
As preferably, between described annular rubber ring and U-shaped connecting portion, be provided with base.
As preferably, described base is latticed arc-shaped cavity or A-frame.
As preferably, described base is plastic feet.
As preferably, the aperture of described latticed arc-shaped cavity base is 0.1 ~ 0.2mm.
Beneficial effect: than prior art, air cleaning unit advantages of simple of the present utility model, can put into the nasal cavity of human body, play the effect that filtration, purification enters air in nasal cavity, the filter membrane that the utility model device adopts is nano fibrous membrane, this filter membrane can filter out the fine solid particle that particle diameter is 0.25um, therefore can reach the effect of better filtration, purification air.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model air cleaning unit;
Fig. 2 is that the utility model air cleaning unit is with the cross-sectional structure schematic diagram of rubber ring;
Fig. 3 is that the utility model air cleaning unit is with the structural representation of rubber ring and A-frame base;
Fig. 4 is that the utility model air cleaning unit is with the structural representation of rubber ring and latticed arc-shaped cavity base.
The specific embodiment
As shown in Fig. 1 ~ 4, a kind of air cleaning unit, comprise U-shaped connecting portion 1 and two air cleaning portions, two end points of described U-shaped connecting portion 1 are fixedly connected with two air cleaning portions respectively, described air cleaning portion comprises nanofiber filter membrane 2, the thickness of described filter membrane 2 is 2 ~ 3mm, wherein, filter membrane 2 is cylindrical, the aperture of filter membrane 2 is 0.25um, air cleaning portion also comprises the annular rubber ring 3 that is looped around filter membrane 2 sidewall surfaces, and annular rubber ring 3 is fixedly bonded together with filter membrane 2; Annular rubber ring 3 is made by the rubber with elasticity and stickiness, therefore annular rubber ring 3 not only has shrinkage, but also there is certain sticky stickiness, when this device is placed in nasal cavity, because annular rubber ring 3 is combined better with the contact-making surface of nasal cavity, so air is difficult for from the gap between annular rubber ring 3 and nasal cavity through and enters nasal cavity inside; Between annular rubber ring 3 and U-shaped connecting portion 1, be provided with base for supporting 4, annular rubber ring 3 is fixedly connected with base for supporting 4, base for supporting 4 can be latticed arc-shaped cavity, also can be A-frame, base 4 plays a supportive role, base 4 adopts soft plastic to make, and when base 4 is latticed arc-shaped cavity, its aperture is 0.1 ~ 0.2mm.
When needs are used this air cleaning unit, by two parallel nasal cavities of putting into of air cleaning portion, U-shaped connecting portion 1 is placed on the junction in two nostrils, and filter membrane 2 is sent into the air after filtration, purification in nasal cavity; When not needing to use this device, along U-shaped connecting portion 1, air cleaning portion is pulled out in nasal cavity.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
