FIG. 2 is a cross-sectional view A-A of FIG. 1;

fig. 3 is a schematic perspective view of the second storage bag of the present invention after being unfolded.

In the figure: the mask comprises a mask body 1, a lining 1-1, fabric 1-2, a hanging belt 2, a lap cover 3, a first storage bag 4, a metal strip 5, a sponge sealing gasket 6, a second storage bag 7, isolation paper 8 and an adhesive layer 9.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3: the rectangular mask body 1 is formed by fixedly connecting a lining 1-1 and a fabric 1-2 into a whole in a superposition mode by sewing or heat sealing, and hanging belts 2 are fixed on the left side and the right side of the mask body 1. A strip-shaped sponge sealing gasket 6 is fixed between the face fabric 1-2 and the lining 1-1 and close to the edge of the upper part of the mask body 1, and a metal strip 5 is wrapped in the sponge sealing gasket. A first receiving bag 4 which is fixed along the horizontal direction by sewing or heat sealing and has an upward opening is arranged on the inner surface of the mask body 1 (namely the surface of the back lining 1-1) near the lower edge, and a second receiving bag 7 which is folded into a strip shape is fixed in the first receiving bag. A cover 3 for covering the mouth of the first storage bag 4 is fixed to the inner surface of the mask body 1 (i.e., the surface of the back sheet 1-1), and this cover can prevent the second storage bag 7 from being contaminated by the contact with the skin of the lower jaw and also prevent the second storage bag 7 from being separated from the first storage bag 4 and scattered. The length and width of the second receiving bag 7 after being unfolded should be slightly larger than the height and width of the mask body 1.

In order to avoid the reduction of the protection effect caused by the fact that the mask body 1 is wet due to long-time wearing, or in order to enhance the protection effect in places (such as an engine room and a carriage) where people are concentrated and the space is relatively closed, the second storage bag 7 is made of a material, such as non-woven fabric, which is the same as the fabric 1-2 or the lining 1-1. On the basis, in order to ensure that the second storage bag 7 can be well combined with the fabric 1-2 after being unfolded, an adhesive layer 9 is fixed on the surface of the second storage bag 7, and the surface of the adhesive layer is covered with a piece of isolation paper 8.

In order to better isolate, accomodate gauze mask body 1, avoid it to suffer pollution such as water stain, dust, the second is accomodate bag 7 and also can be made by plastic film.

In order to adapt to wearing of people with different face shapes and avoid gaps between cheeks on two sides of a person with a thin face shape when the person wears the mask, elastic bands (not shown in the figure) are fixed between the fabric 1-2 and the lining 1-1 and at positions close to the left side and the right side of the mask body 1, and the two elastic bands respectively tighten the two sides of the mask body 1 in the height direction.

The using method comprises the following steps:

during the use, wear gauze mask body 1 in face through two strings of bands 2, then press the sponge sealed pad 6 in the both sides of bridge of the nose, make its metal strip 5 of parcel take place to warp and form with the first radian to of bridge of the nose both sides curve. Under the action of the deformed metal strip 5, the sponge sealing gasket 6 with certain elasticity can be tightly attached to the cheeks on two sides of the nose bridge to fill a gap between the nose bridge and the cheeks; thereby not only blocking the hot air atomization glass slide which is exhaled, but also preventing dust, germs and the like from entering the respiratory tract from the gap. In addition, the second containing bag 7 has certain elasticity after being folded into a strip-shaped structure, and can be well attached to a mandible curve, so that the airtightness of the mask is further improved.

After the mask storage bag is used, the second storage bag 7 is only required to be pulled out of the first storage bag 4 and unfolded, the bag opening of the second storage bag 7 is turned upwards, and then the mask body 1 is stuffed into the second storage bag 7 to store the mask. When the mask needs to be used again, the mask body 1 is taken out of the second storage bag 7, and the second storage bag is folded into a strip-shaped structure and is stuffed into the first storage bag 4.

When the wearing time of the mask needs to be prolonged or the protective capability of the mask needs to be enhanced in some occasions, the second storage bag 7 (made of non-woven fabric) is pulled out of the first storage bag 4 and unfolded, the release paper 8 is uncovered, and then the second storage bag 7 is adhered to the surface of the lining 1-1 through the adhesive layer 9.
