Description

Folding non-woven fabric mask

Technical Field

The utility model relates to a breathe with protection product, especially relate to a gauze mask.

Background

The conventional mask includes a mask body 11 mainly made of non-woven fabric. The mask body 11 is generally divided into three layers, the outer and inner layers are respectively made of non-woven fabrics, and the middle layer is made of melt-blown fabric. The upper edge of the cover body 11 is provided with a shapeable supporting rib, and the upper edge is shaped when the mask is worn. The middle part of the cover body 11 is provided with a plurality of folding layers which extend transversely to form a folding part 13. The two sides of the cover body 11 are respectively and fixedly provided with a fastening piece 12, and the fastening pieces 12 can be binding bands, ear bands or bands, etc. The folded non-woven mask is flat when packaged for sale, as shown in fig. 1. The mask is mainly used for blocking spray and dust, and the requirement on air tightness is not high. When in use, the mask body 11 is fixed in front of the nose 20 and the mouth by the fastener 12, and the folded part 13 is stretched and unfolded in the up-down direction, as shown in fig. 2 and 3. Air ingress and egress now primarily occurs from a region near the nostrils through the folds 13 and partially from the edge regions of the cover 11.

When the wind blowing to the face is large, or when riding a bicycle or running, the situation as shown in fig. 4 is likely to occur. The folds 13 are pressed against the nostrils by air which enters into a position substantially corresponding to the size of the nostrils at the folds 13. Since the filtering area is greatly reduced, it becomes difficult for a person to inhale air, and the local filtering of the folded portion 13 is overloaded to reduce the filtering effect. Dirt accumulates substantially close to the nostrils, often forming two dark circles.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a folding non-woven mask.

The utility model relates to a folding non-woven gauze mask, which comprises a mask body, wherein both sides of the mask body are respectively connected with a fastener, and the middle part of the mask body is provided with a transversely extending folding part; the folding part is provided with a transversely extending supporting piece which is fixedly connected with the folding part.

The supporting piece is a plastic sheet, a silica gel sheet or a metal sheet.

The cover body comprises an outer non-woven fabric, a melt-blown fabric and an inner non-woven fabric which are sequentially stacked; the support piece set up in between inboard non-woven fabrics and the melt-blown fabric, and side and inboard non-woven fabrics fixed connection.

The supporting piece is arranged on one side, close to the face, of the cover body, the left end portion and the right end portion of the supporting piece are respectively provided with a fixed disc, and the fixed discs are fixedly connected with the folding portions.

A foldable non-woven fabrics gauze mask, its advantage lies in, but forms the arch bridge through the support piece of elastic bending when wearing and prevent that the folding portion is attached to the nostril. Breathing difficulties can be avoided and local filter pressure increases are not encountered. Meanwhile, an unexpected technical effect is also obtained: lens fogging of a user wearing the glasses is avoided.

Detailed Description

As shown in fig. 5, the foldable non-woven mask of the present invention comprises a mask body 11, wherein the mask body 11 generally comprises three layers, from outside to inside, respectively comprising an outside non-woven fabric, a melt-blown fabric and an inside non-woven fabric. The upper edge of the cover body 11 is provided with a shapeable supporting rib, and the upper edge is shaped when the mask is worn. The middle part of the cover body 11 is provided with a plurality of folding layers which extend transversely to form a folding part 13. The two sides of the cover body 11 are respectively and fixedly provided with a fastening piece 12, and the fastening pieces 12 can be binding bands, ear bands or bands, etc. The folding part 13 is further provided with a support member 14 extending left and right, and the support member 14 can be a strip-shaped article with elasticity, such as a plastic sheet, a silicon sheet or a metal sheet. The aim is to form an arch bridge which protrudes outwards when worn, so as to support the folding part 13 and avoid the folding part from falling to the nostril. The supporting member 14 may be disposed in various ways, such as on the side of the inner non-woven fabric adjacent to the human face, and then the supporting member 14 is fixedly connected to the folding portion 13. Or the supporting piece 14 is arranged on the side of the inner non-woven fabric far away from the human face, and then the side surface of the supporting piece 14 is fixedly connected with the folding part 13.

When the supporting member 14 is disposed on the side of the inner non-woven fabric close to the human face, two end portions of the supporting member 14 may be respectively disposed with a fixed disc, the fixed discs are used for being fixedly connected with the folding portion 13, and other portions of the supporting member 14 are not fixedly connected with the folding portion 13. The device is convenient to produce and can be realized only by a hot-pressing dotting mode.

When in use, the folding part 13 is stretched and unfolded up and down, and both sides of the cover body 11 are bent towards the human face. The support 14 will then follow the deformation and form a camber away from the face, as shown in figures 6 and 7. Due to the support member 14, the fold 13 is prevented from collapsing toward the nostril, and the user does not affect breathing while riding or running.

In solving the problem of collapse of the folding part 13, the novel mask further obtains unexpected technical effects and solves the problem of lens atomization when a user wearing the glasses uses the mask. The shape of an air cavity formed between the folding part 13 of the original mask and the mouth and the nose is similar to a peach shape with the upper tip and the lower width, air pressure of air flow at the nose 20 is large when the mask exhales, the air flow easily breaks through the edge near the nose 20 and is ejected, and the exhaled hot air reaches the lens to atomize the lens. And after the utility model is provided with the supporting piece 14, because the supporting piece 14 transversely extends and has certain elasticity, the original air cavity is transversely stretched. The stretching deformation, although not large, is sufficient to reduce the pressure impact of the gas flow near the nose 20, resulting in more exhaled gas being directed to the left and right. The amount of air flowing out of the vicinity of the nose 20 is greatly reduced and is not sufficient to fogging the lens.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
