Background

A plurality of protective masks are available in medical treatment, some masks are anti-virus and also are dustproof, but the existing masks are not tightly attached to the face of a human body, so that dust and viruses enter respiratory tracts to cause the masks to lose due functions. At present, the problem has been noticed, and some measures have been taken, such as an iron clip provided at the nose bridge, which is pinched to fit the nose bridge when the mask is worn, but the iron clip is loosened and fatigued, and the iron clip cannot completely prevent dust and viruses from entering from the gap between the mask and the face. The iron clip obviously cannot enable the gap between the mask and the face to be in a micron scale matched with the filtering capacity of the mask.

For example, in china, some medical staff wear a four-layer mask to prevent virus inhalation, but the mask is still infected with virus, and the reason for this is that the mask is not well protected, but after wearing the four-layer mask, the ventilation capacity of the mask is poor, so that air directly enters from the gap between the mask and the face, and the effect of wearing the mask is worse than that of wearing a single-layer mask.

These masks cannot prevent viruses from entering from the gap between the mask and the face of the human body.

Because the shapes of human faces are different, the nose bridge of eastern people is lower, and the nose bridge of western people is higher, so that the mask is difficult to completely fit with the faces of everyone. And articles such as gas masks and waterproof glasses are also required to be sealed with the face of a human body, so that a mask is necessary to be designed aiming at the problem of the fit between the face of the human body and the mask.
