Abstract

The utility model discloses a disposable mask for preventing glasses from fogging, which comprises a mask main body and two ear lines arranged on the frame part of the mask main body, wherein a nose bridge strip is nested in the mask main body, an anti-fog sheet is arranged at the upper end of the outer part of the mask main body, the anti-fog sheet is folded into an M shape by a melt-blown fabric and a non-woven fabric in a double-layer mode, a flock-sprayed fabric is arranged on the outer layer of the anti-fog sheet and fixed on the upper edge of the inner side of the mask main body to form a double-inverted-V-shaped elastic folding space, and the mask main body is made by wrapping flock-sprayed fabric by two layers of non-woven fabric. According to the utility model, when air exhaled by a human body moves upwards, most of gas enters the double-inverted-V-shaped space of the anti-fog piece, so that the double-inverted-V-shaped anti-fog piece is opened towards two sides, the anti-fog piece is enabled to be attached to the face more tightly, the gas exhaled by the human body is reduced from overflowing from the gap between the upper part of the mask and the face, and the side edge of the anti-fog piece close to the face extends between the face and the mask, so that the attaching area of the anti-fog piece and the face is increased, and the water vapor is blocked from flowing to glasses to form water mist.

Description

Disposable mask for preventing glasses from fogging

Technical Field

The utility model belongs to the technical field of sanitary protection tools, and particularly relates to a disposable mask capable of preventing glasses from fogging.

Background

The mask is a sanitary protective tool, is used for preventing harmful particles in the air such as dust, bacteria, pollen, PM2.5 and the like from entering nasal cavities and lungs, can prevent germs from spreading due to saliva splashing, and is widely applied to medical treatment, labor protection and public trip. The gauze mask needs the fine laminating of gauze mask and face in order to guarantee breathing occasionally good safeguard effect, and the gas that otherwise breathes has the gap from face and gauze mask to pass. A concave outline is arranged between the face and the nose bridge, and the upper edge of the disposable mask is folded into an arc shape by using a thin metal rod or a thin sheet nose bridge strip, so that the upper part of the mask is attached to the nose bridge. The arc shape of metal bending is basically fixed, and the muscle of people's face bridge of the nose both sides is movable, and the unable high accuracy of fixed gauze mask shape matches the people's face curved surface of activity, exists the gap. When the weather is cold, when a person exhales, damp and hot gas and water vapor which run out from a gap at the upper edge of the disposable mask form too small liquid drops on the relatively cold glasses, and the too small liquid drops are attached to the glasses to form water mist, so that the sight of the person is blocked, and the safety is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that in the prior art, water vapor is attached to a spectacle point to block the sight of a person and influence the safety, and provides a disposable mask for preventing spectacles from fogging.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent disposable gauze mask of glasses fogging, includes the gauze mask main part and sets up two ear lines at gauze mask main part frame the inside nestification of gauze mask main part has the bridge of the nose strip the outside upper end of gauze mask main part is provided with antifog piece.

Preferably, the antifogging piece is folded into an M shape by a melt-blown fabric and a non-woven fabric, the melt-blown fabric is positioned on the outer layer of the antifogging piece and fixed on the upper edge of the inner side of the mask body to form a double-inverted V-shaped elastic folding space.

Preferably, the mask body is made of two layers of non-woven fabrics wrapping the flock spraying cloth.

Preferably, the mask body adopts a three-layer folding design in the middle.

Preferably, the ear line is made of an elastic material.

Compared with the prior art, the utility model has the beneficial effects that:

when the air exhaled by the human body moves upwards, most of the air enters the double-inverted-V-shaped space of the anti-fog sheet, so that the double-inverted-V-shaped anti-fog sheet is opened towards two sides, the anti-fog sheet is enabled to be attached to the face more tightly, and the phenomenon that the air exhaled by the human body overflows from gaps between the upper part of the mask and the face is reduced;

between the face and the mask, the side edge of the anti-fog piece close to the face extends to increase the attaching area with the face, and the water vapor is blocked from flowing to the glasses to form water fog.

Drawings

Fig. 1 is a top view of a disposable mask for preventing fogging of glasses according to the present invention.

Fig. 2 is a side view of a disposable mask for preventing fogging of glasses according to the present invention.

In the figure: 1 mask body, 2 ear lines, 3 nose bridge strips and 4 antifogging sheets.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1, a prevent disposable gauze mask of glasses fogging, adopts the three-layer filtration including gauze mask main part 1, and outer non-woven fabrics prevents large granule, saliva foam, and the intermediate level is the melt-blown cloth, filters fine particle, and the inlayer non-woven fabrics, compatible skin adopts the folding design of three-layer in the middle of the gauze mask main part 1, and the breathing space is bigger.

The two ear strings 2 provided on the frame of the mask body 1 are made of elastic material.

Referring to fig. 2, the anti-fog sheet 4 is folded into an M shape by using a melt-blown fabric and a non-woven fabric, and the outer layer of the anti-fog sheet 4 is provided with a flock fabric which is fixed on the upper edge of the inner side of the mask body 1 to form a double-inverted V-shaped elastic folding space.

Nose bridge strip 3 is transversely embedded in the gauze mask upper end, plays the gauze mask and fixes the effect on the bridge of the nose.

When the air of human exhalation upwards removed, most gas got into the two type of falling V spaces of antifog piece 4, made two type of falling V antifog pieces 4 open to both sides, made antifog piece 4 laminating face inseparabler, reduced human exhalation gas and overflowed from gauze mask upper portion and face gap.

Between the face and the mask, the side edge of the anti-fog piece 4 close to the face extends to increase the attaching area with the face, and the water vapor is blocked from flowing to the glasses to form water fog.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
