Mask

Abstract

The invention provides a mask which mainly comprises a mask body and tying belts, and the mask body comprises a wrinkle surface, a flat edge, a pull-limiting elastic line and a nose bridge strip; a wrinkle-free flat edge is arranged on the periphery of the wrinkle surface, and a tension-limiting elastic line perpendicular to each wrinkle line is arranged on the wrinkle surface; the nose bridge strip is arranged on the flat edge of the upper edge. When the mask is packaged and stored, wrinkles are folded into a plane shape, and when the mask is used, the wrinkles are opened to a certain degreeto form a bowl shape. The mask wrinkle structure ensures three-dimensional filtration, the tension-limiting elastic lines can prevent wrinkles from being flattened, the mask can be prevented from being pulled to the lower jaw and covering the neck to lose a filtration effect, and it is ensured that the filtration area is large and the inspiration resistance is small; the structure is simple, the mask conforms to ergonomics, the protection performance is good, and wearing is comfortable.

Description

technical field [0001] The invention belongs to the technical field of mask production and relates to a novel mask based on enhanced filtration and ergonomics. Background technique [0002] Mask is a kind of sanitary product, which is worn on the mouth and nose to filter the air entering the mouth and nose, thereby intercepting droplets, viruses, harmful gases and dust, etc. [0003] Existing mouth mask has cup type, flat type etc. from overall shape, and has wrinkle type and wrinkle-free type from details. The pleated mask is a three-dimensional filter with a large filter area, and the filter surface is rigid, so it is not easy to stick to the face, ensuring an effective filter area. The non-pleated mask is a flat filter with a small filter area, and it is easy to stick to the face to reduce the effective filter area. Existing cup type masks are generally all non-wrinkle type. There are pleated and non-pleated types of flat masks. However, the existing pleated masks are...

AI Technical Summary

Problems solved by technology

However, the existing pleated masks are often flattened during use, and a large part is pulled to the lower jaw or even lower, covering the neck and losing the filtering effect

The reduction of the effective filter area will inevitably increase the filter resistance and affect the breathing

In addition, the moisture exhaled by traditional masks is difficult to discharge from the mask, which makes the mask damp and further increases the filtration resistance. The longer the wearing time, the greater the breathing resistance, and the bacteria are easy to survive.

Furthermore, traditional masks do not fully consider ergonomics. The seal around the mask, especially on both sides of the bridge of the nose, is poor, which is prone to air leakage, short-circuiting the inhalation, and affecting the protective performance of the mask. At the same time, the exhaled moisture will pass through the bridge of the nose. The passages on both sides are discharged upwards, passing through the glasses, and the water vapor condenses on the lenses, affecting the vision of the wearer
