Abstract

A disposable protective mask, comprising a mask body (10) and elastic connecting pieces (20) connected at both sides of the mask body (10) and used for hanging on the ears. Multiple rows of fold parts (11) capable of being extended during wearing to increase the width of the mask body (10) are provided on the mask body (10) along the width direction of the mask body (10); the left and right side ends of the mask body (10) have the same width ranging from 45 to 55 mm; two ends of each elastic connecting piece (20) are both fixedly connected at the same side of the mask body (10), and a spacing between the positions where the two ends of the elastic connecting piece (20) are connected onto the mask body (10) ranges from 25 to 45 mm; the lower side end of the mask body (10) is further connected to an elastic piece (13). The problem of a reduced protective effect resulting from an existing mask being not strong in air tightness because after wearing, the middle of the lower, left, and right edges will be clearly warped up can be solved.

Description

Disposable protective mask

Technical field

The utility model belongs to the technical field of medical or civil mask structures, in particular to a disposable protective mask.

Background technique

Masks are a necessity in the general medical or civilian mask market, and are also protective products for people who are susceptible to colds or allergies. Because the unit price is low, the existing disposable masks in the market adopt the three-fold method, and the width of the two ends of the mask is 95mm. In order to facilitate the wearing of the mask, an elastic band is generally fixed on both ends of the mask, and usually the elastic band is connected to the mask. The width of the upper part is greater than or equal to 90mm, which causes the elastic band to be tightened after wearing, so that the lower part of the mask and the left and right sides are obviously lifted, and the mask can not be closely attached to the face and the chin, and the airtightness is not strong, resulting in protection. The problem of reduced performance.

Utility model content

The purpose of the utility model is to provide a disposable protective mask, which aims to solve the problem that the sealing effect is reduced due to the obvious lifting of the lower edge and the left and right side edges after the existing mask is worn.

The widths of the left and right ends of the mask body are the same, and both are 45-55 mm. The elastic connecting members are respectively fixedly connected to the two side edges of the mask body, and the two ends of the elastic connecting member are connected to the mask body at a distance of 25 to 45 mm, and the upper end of the mask body is provided with The bridge of the nose has a loose member attached to the lower end of the mask body.

Further, the bridge of the nose can be bent and attached to the bridge of the nose, the bridge of the nose is sewn on the body of the mask, and the bridge of the nose is located at an intermediate position of the upper edge of the body of the mask.

Further, the number of rows of the pleats is greater than or equal to four rows, and the adjacent two rows of the pleats are parallel to each other.

Further, the maximum width of the mask body after the plurality of rows of the pleats are fully deployed is greater than or equal to 170 mm.

Further, the surface of the mask body has a rectangular shape, and the length of the mask body is greater than or equal to 220 mm.

Further, the elastic member is disposed in the middle of the lower side end of the mask body, and the length of the elastic member is 65-90 mm, and the width of the elastic member is greater than or equal to 6 mm.

Further, the elastic connecting member has an adjusting member for adjusting the wearing tightness of the mask body, and the adjusting members are respectively disposed on the two elastic connecting members.

Further, the mask body comprises a first cotton fabric layer, a filter cotton layer and a second cotton fabric layer, the first cotton fabric layer is located on the outer side, and the second cotton cloth is located on the inner side and is attached during use. The filter cotton layer is coupled between the first cotton fabric layer and the second cotton fabric layer.

Further, the second cotton fabric layer is white, and the first cotton fabric layer is white, green, blue or pink.

Further, the bridge of the nose is a metal nose strip.

The disposable protective mask provided by the present invention has the technical effect of reducing the length of the left and right side edges of the mask body to be close to half of the conventional mask, and at the same time, achieving the width requirement by providing a plurality of rows of pleats. At the same time, the distance between the elastic connecting members on the sides of the mask is 25 to 45 mm, so as to avoid the two sides of the mask body being tilted along the center position when wearing, and the lower side edge of the mask body is connected with the elastic member, and then Making the lower edge of the mask body more It is well fastened to the wearer's chin, so that the entire structural design avoids the problem that the protective effect is lowered due to the fact that the lower edge and the left and right sides are significantly tilted in the middle position after wearing on the market, and the airtightness is not strong.
