Abstract

A respirator can improve the flow amount of the filtrated air by supporting the mouth and nose part with a space when wore through an arc casing frame sewed in the filtrating layer, and thereby providing a larger area for air filtrating at the mouth and nose part, which can eliminate the oppressed sense for users.

Description

Mouth mask

Technical field

The utility model relates to a kind of respiration filtering device, specifically a kind of mouth mask.

Background technology

Mouth masks such as dustproof, the anti-germ of producing, selling and uying in the market, generally all use cotton gauze or nonwoven to make, the cotton gauze of mouth mask generally between 8 layers to 16 layers, is made one deck cotton or other fibrous materials and is used as filtering between the two-layer cotton of the usefulness that also has.But because the quality softness of cotton system or fibrous material, the user puts on the back, and it just is close to the place, nostril, the filter area of the mouth mask that is passed through during breathing is less, thereby make that the air capacity of passing through is limited, will make the people feel to feel oppressed very much, after wearing especially for a long time, can make schneiderian membrance become fragile, influence the original physiological function of nasal cavity, simultaneously, owing to after the physiological characteristic at people's mouth, nose place makes that mouth mask is put on, can form certain space in the both sides of nose, germ, dust, dirt are easy to enter from the gap of nose both sides, have influence on the filtration of mouth mask.

Summary of the invention

The purpose of this utility model is exactly in order to solve the deficiency that the above-mentioned background technology exists, a kind of air filtration area that can increase the place, nostril is proposed, can prevent that again germ, dust, dirt from entering from the space of nose both sides and the edge of mouth mask, thereby strengthen the mouth mask of filtration.

In order to realize the foregoing invention purpose, the utility model adopts following solution: a kind of mouth mask, it is characterized in that it comprises cotton gauze or the nonwoven and the arc shell frame of filter course, the marginal portion that described arc shell frame contacts with people's skin is the mouth according to the people, the surface at nose and chin place is designed the edge contour of arc shell frame, arc shell frame is made in cotton gauze or nonwoven layer, mouth the wearer, prop up and overhang certain space at the nose place, airfiltering area increases when putting on the back breathing, thereby increase the circulation of air, reduce the sensation of feeling oppressed when breathing.

In such scheme, the described available plastics of arc shell frame or other metal materials are made, it has a large amount of holes so that air filters by the cotton yarn layer of cloth on arc shell frame, simultaneously the profile at the profile of itself and skin contact position and people's mouth, nose and chin place matches, and makes that the space between mouth mask and the skin is remedied.

Arc shell frame in such scheme is in the process of making, with people's skin contact position, be lined with certain thickness spongy layer, the person of wearing is felt comfortably cool, simultaneously can prevent that again germ, dust, dirt from entering from the gap of mouth mask and skin, prevent that unfiltered air from entering human body.

The utility model features simple structure, easy to use comfortable, Yin Qinei has arc shell frame, and the filtration yield of air is bigger, reduces the sense of feeling oppressed, and can prevent general mouth mask again because of can't distinguishing ectonexine, and the skin that will use is used as the internal layer use, influences the effect of mouth mask.

Description of drawings

Fig. 1 is the profile of mouth mask;

Fig. 2 is an arc shell frame outline drawing;

Among the figure: 1, be the mouth mask filter course; 2, be arc shell frame; 3, be air-vent.

The specific embodiment

Embodiment of the present utility model is, between the filter course 1 that two-layer cotton gauze or other materials are made, makes an arc shell frame 2, after air enters internal layer and filters by the outer filter layer and through air-vent 3 on the arc shell frame, for human body respiration.Mouth, nose place support certain space when wearing, and strengthen airfiltering area, thereby increase the circulation of air, feel comfortably cool when allowing the user breathe.

Claims

1, a kind of mouth mask is characterized in that an arc shell frame is arranged in the middle of filter course.

2, arc shell frame according to claim 1 is characterized in that the edge contour with the human body skin contact position is to match with people's mouth, the physiological characteristic at nose place.

3, arc shell frame according to claim 1 is characterized in that on the arc shell frame air-vent being arranged.
