Background

The mask is a sanitary article, has a certain filtering effect on air absorbed in a human body, is generally worn at the mouth and nose part for filtering air entering the mouth and nose when in use so as to achieve the effect of blocking harmful gas, smell or spray from entering and exiting, and has a very good filtering effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like when in epidemic operation.

The existing mask mainly comprises a mask body for filtering foreign matters, wherein the mask body is used for fixing the mask body on an ear hook which is hung on the face and the ear, a metal pressing strip is arranged on the upper part of the mask body, and the main function of the pressing strip is to shape the upper edge of the mask body, so that the upper edge of the mask body is attached to the face, and the sealing effect of the mask body is enhanced. However, in actual use, after the mask body is worn on the face, although the mask body is shaped by the batten, gaps always appear on the two sides of the nose bridge, the cheeks and the upper edge of the mask body; meanwhile, after the mask is worn, the lower part of the mask body forms an inclined plane which is just positioned below the nose expiration, so that the expiration meets the blocking of the inclined plane and is rebounded upwards, and the phenomenon of air leakage above the mask body is avoided. Based on the defects of the common mask, when the weather is cold, the common mask exhales between expiration and exhalation, the expiration leaks from the upper edge of the mask body, and particularly, a layer of fog is covered on the glasses of the glasses, so that the eyesight is affected, and the mask is very inconvenient.

Although the N95 mask in the existing mask is more compact than the common disposable medical mask, the N95 mask still has the phenomenon that the two sides of the nose bridge and the upper edges of the cheeks and the mask body are not tightly combined, and medical workers can only strengthen the fastening degree of the hanging rope to avoid the phenomenon, so that the edge of the N95 mask excessively presses the face of the medical workers to form deep tightening marks. In practical use, although the fastening degree of the reinforcing hanging rope can enhance the combination of the edge of the mask body and the face to a certain degree, a small amount of breath still leaks from the upper edge of the mask body, which is limited by the structure of the mask body and cannot be avoided. When the medical staff wears the goggles, the lower part of the goggles is pressed on the outer side of the upper part of the cover body, so that the face is completely sealed. After long-time wearing, the humidity in the goggles is inevitably increased by leaked exhalations, and the main reason of fogging of the goggles is that the exhalations cannot be avoided.
