Description

Structure improved mask

Technical Field

The invention belongs to the field of personal respiratory protection, and particularly relates to a mask with an improved structure.

Background

Patent 972150706 provides a gauze mask of improvement structure, and simple and effective preparation gauze mask that can be simple and convenient, though reduce compared with traditional gauze mask gap, because everyone's the bridge of the nose height width is different, the position uncertainty when wearing still can have the gap to produce in the alar department of nose. There are also products that adopt the gauze mask top soil preparation to turn over to the inboard, but because when turning over as whole, when with the crooked curved surface laminating of nasal part, turn over to the inboard and receive the laminating curved surface influence, can not fully laminate with the skin of nose wing department, therefore patent 201520592386X provides a gauze mask that prevents to breathe steam atomizing glasses, and the upper portion that adopts the face guard body has the folding part of buckling at the face guard body inboard, and its folding part adopts triangle-shaped's mode and closely laminates with the bridge of the nose of the person of wearing. The method also has the problem that the nose cannot be completely matched with the triangular gap due to different heights and sizes of the nose of different users because the triangle is in a fixed shape.

Disclosure of Invention

The invention provides a structure-improved mask, in particular to a structure-improved mask which is in accordance with different face shapes, can effectively seal gaps at the mouth and nose and is simple and convenient to manufacture.

The technical scheme adopted by the invention is as follows: a structure improved mask is characterized in that the edge of the top of the mask is turned inwards and arched; the center of the mask top fabric is prefabricated with a V-shaped notch, two edges of the V-shaped notch are provided with symmetrical bending points, the two edges of the V-shaped notch are respectively bent at the bending points to be mutually closed and attached fixedly, the edge of the top of the mask is inwards folded along the bending points, the folded part of the edge of the top of the mask, which is positioned at two sides of the mask, is attached fixedly with the mask body, the length of the folded fabric between the two sides of the inwards folded fabric at the top of the mask and the V-shaped notch is greater than that of the corresponding folded fabric at the mask body, and the folded fabric forms natural arching at the position close to the V.

When the mask is not folded, two edges of the V-shaped notch of the mask are bent, 2 line segments are formed on each edge at the bending point, the line segment or the upward extension line positioned above the mask is intersected with the symmetrical line segment or the extension line of the other edge, and when the formed included angle is larger than the included angle at the top end of the V-shaped notch of the mask, the edge of the top of the mask at the bending point can be bent horizontally or inwards towards the center of the mask to form an arch; when the included angle formed is smaller than the included angle at the top end of the V-shaped notch of the mask, the edge of the top of the mask at the bending point can only be bent inwards towards the center of the mask and forms an arch. The height of the arch part is different along with the difference between the angle formed by the two line segments of the bending point of the V-shaped notch and the length of the upper line segment of the bending point on the two edges of the V-shaped notch. The attaching and fixing mode adopts sewing, ultrasonic welding and other modes.

The top of the mask is arched by 1 to 10 layers of fabric. When 1-10 layers of fabrics are arranged at the top end of the mask, the length of each layer of fabrics is different, and the length of the fabric close to the skin from inside to outside is gradually shortened. Because longer arches, particularly stiffer materials, can deform to create gaps when in contact with the face, better sealing can be achieved when an arch of appropriate length is in contact with the face.

The left side and the right side of the V-shaped notch of the mask are respectively provided with 2 symmetrical bending points.

The arched edge at the top end of the mask is in a sawtooth shape. The zigzag is used for releasing tension generated by the fabric when the fabric is bent, so that the fabric can be better attached to the skin.

The top end of the mask is arched, and the interior of the top end of the mask is filled with an elastic body. Further increasing the flexibility and conformability of the fold.

The inner surface and the outer surface of the mask are made of at least 1 of antibacterial materials containing silver ions, silver fibers, zinc oxide, copper ammonia fibers, photocatalyst-free materials, chitin, bamboo fibers, hemp fibers and the like.

The upper bridle arched and connected with the top end of the mask extends to the root of the ear.

The invention utilizes the characteristics that the mask fabric has different lengths in the cutting and punching processes and generates soft arching when being attached and fixed, and compared with the prior art, the invention has the characteristics of simple and convenient manufacture, excellent sealing effect and suitability for most people.

Detailed Description

The specific structure of the invention is further explained by combining the drawings and the embodiments.

In specific embodiment 1, as shown in fig. 1 and 2, a non-woven fabric mixed with nano zinc oxide and graphene is cut into a shape shown in fig. 1, a V-shaped notch is formed in the center of the top end, the included angle between the vertex of the V-shaped notch and the vertex is 90 degrees, the included angle is 3 cm away from the vertex, bending points 1 are arranged on two sides of the V-shaped notch, the bending angle is 135 degrees, and the V-shaped edge extends upwards for 3 cm from the bending point 1. The top of the mask is folded inwards along the bending line 2, so that the V-shaped gap is positioned at the upper and lower sides of the bending point 1 and overlapped with each other. The mask is folded inwardly along the middle fold line 4, the V-shape is closed and ultrasonically sealed. The upper edges 3 of the two sides of the top end of the mask are arched, and the arched upper edges 3 are filled with sponge 6. Two ends of the mask are provided with laces 5.

Embodiment 2, silver-containing antibacterial auxiliary agent finished cotton-flax and spandex blended fabric, cut into the shape as shown in fig. 3, mask top and bottom have V-arrangement breach along middle broken line 4 respectively, wherein the contained angle at the V-arrangement breach summit on top is 60 degrees, total length 5.5 centimetres, apart from summit 1.5 centimetres and 2 centimetres department, there are symmetrical 2 buckling points 1 on the V-arrangement breach both sides on top, divide into upper buckling point 10 and lower buckling point 11, the last border 3 of mask top both sides is buckled along upper bending line 20, after the V-arrangement breach both sides that are located upper and lower both ends of upper buckling point 10 are laminated, the V-arrangement breach both sides of top and bottom are closed and are sewed up. The sewed mask is folded outwards at the lower bending point 11 along the lower bending line 21. The mask shown in fig. 4 is formed, and the upper edge 3 of the mask is provided with saw-teeth with a height of 3 mm and a tooth width of 3 mm. The two ends of the mask are sewed with a lacing 5 along the upper bending line 20.

Embodiment 3, as shown in fig. 5, the bamboo fiber and chitosan blended fabric is cut along the middle folding line 4 into a bamboo fiber and chitosan blended fabric with 1V-shaped notch at the top and bottom, wherein two sides of the upper V-shaped notch are provided with 2 symmetrical bending points 1, which are divided into an upper bending point 10 and a lower bending point 11. The upper edges 3 at the two sides of the top end of the mask are provided with saw-tooth structures with the height of 3 mm and the tooth width of 3 mm. The outer surface of the upper edge 3 is sewed with 2 layers of cloth with the sawtooth height of 2 mm at the positions 4 mm and 8 mm away from the sawtooth edge to form the sealing of the 2 nd layer and the 3 rd layer.
