When the filter is used, the filter is plugged into the nostril, is fixed by clamping the columella nasi and is supported by the tension of the nasal plug, on one hand, any object plugged into the nasal cavity easily stimulates the nasal mucosa to cause discomfort of a user, and the object plugged into the nasal cavity for a long time can cause discomfort and can cause the user to be unwilling to wear; on the other hand, after the nasal plug is plugged into the nostril, the effective area is greatly reduced, the filtering efficiency is reduced, more objects are put into the nostril, the breathing passage is blocked, and the breathing is difficult; moreover, the filter device is put into the nasal cavity, and the filtered dirt is temporarily left in the nasal cavity to pollute the human body.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to current filter for the nose perhaps there is the use easily to drop, or there is the inside tight nose columella of relying on clamp of nasal cavity of need putting into to fix, brings discomfort, low and cause defects such as pollution of filtration efficiency for the user, adopts following technical scheme to realize:

a nasal air filter comprising: the filter element fixing hole frames are connected through a connecting part, the middle of the connecting part is arched upwards, and the fixing hole frames are provided with internal threads; the nose wing claws are arranged on the outer sides of the two filter element fixing hole frames; the filter element comprises a cylinder, a thread part positioned at the bottom of the cylinder and a filter body inside the cylinder; and the sponge body is arranged on the periphery of the frame.

Furthermore, the filtering body comprises a sponge layer, a melt-blown fabric and a sponge layer from outside to inside.

Further, the nose wing claw comprises a bent part and an elbow positioned at the tail end of the bent part.

Furthermore, the frame and the cylinder are made of plastics.

Furthermore, the nose wing claws are movably arranged on two sides of the two filter element fixing hole frames.

Furthermore, the material of the nose wing claw is plastic.

Compared with the prior art, the utility model discloses an advantage lies in with positive effect:

on one hand, the utility model is fixed by the middle arch part of the nose wing claw and the connecting part in the wearing process, and basically adopts an external fixing mode, so that the wearer does not feel uncomfortable; on the other hand, the filter element is arranged outside the nasal cavity, so that pollution can be completely isolated outside, and the nasal cavity is prevented from being polluted by contact; on the other hand, the filter element and the frame are fixed through threads and can be replaced timely.

Detailed Description

In order to clearly understand the above objects, features and advantages of the present invention, the present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1 and 2, the present embodiment provides a nasal air filter, which includes a frame 2, nasal prongs 1, a filter element 4, and a sponge 3.

The frame 2 part comprises two filter element fixing hole frames 2-2, the two filter element fixing hole frames 2-2 are connected through a connecting part 2-1, the middle of the connecting part 2-1 is arched upwards to form a mountain tip shape, the fixing hole frames are provided with internal threads, the frame is made of plastic materials, the arched part in the middle of the connecting part plays a role in connecting the two filter element fixing hole frames on one hand, and the arched part made of the plastic materials has certain elasticity and can play a role in clamping when being worn, and on the other hand, the structure can be completely attached to the nose. The frame of the embodiment can be designed into different size specifications according to requirements.

The nose wing claw 1 is arranged at the two side frames of the two filter element fixing hole frames 2-2 and used for clamping the whole filter, and in consideration of light and comfort, the nose wing claw is made of plastic and fixed on the nose and is fixed by the warping degree of the nose wing. The nose wing claw comprises a bent part and an elbow positioned at the tail end of the bent part, and when the nose wing claw is worn, the elbow part just supports against the concave part of the nose wing.
