Description

Folding protective mask

This creation is related to a mask, especially a folding protective mask.

In recent years, air pollution in most parts of the world is very serious and viruses and bacteria often invade human health. In particular, the outbreak of the new coronavirus (COVID-19) in Asia in January 2020 has rapidly spread to the world and threatens the health and lives of the world more seriously, and the WHO It is confirmed that the virus has spread globally through aerosols in the air. As of June 30, 2021, it is estimated that nearly 200 million people have been diagnosed worldwide, and more than 4 million people have died. The situation is very serious. With the rapid increase of the epidemic, With the trend of flu, wearing a mask has obviously become the most important and basic method of preventing new coronary pneumonia today.

Since the outbreak of new crown pneumonia, the demand for masks in various countries has increased greatly. The global demand has reached 100 billion pieces, mainly 80 billion pieces of flat masks, accounting for 80%, and the demand for N95/FFP2 masks also accounting for 12%. It is well-suited for use in isolation wards and higher-risk medical staff or highly polluted environments. For the general public, the tightness of the mask is very important. If the mask does not fit the face tightly, the germs in the air will leak from the poorly fitted face into the inside of the mask, and enter the human body through the respiratory organs, seriously endangering human health .

For example, the existing N95 masks still have the following defects in the structure and use: the upper edge of the mask is equipped with a molded metal sheet. Although the metal sheet is strong but rather rigid, it is difficult to adapt to and conform to the shape, size and height of the individual's nose. It is easy to cause air leakage in the nose and poor tightness. In addition, the hot air exhaled from the body of the mask wearer will also rise from both sides of the bridge of the nose and cause the glasses to fog; in addition, the foam pad is mainly provided It has a tight elastic function, but it has many interconnected pores. The air passing through the foam pad has little filtering effect and poor leakage prevention function; in addition, wearing this type of mask has a sense of pressure and is expensive. -5 times.

One of the purposes of this creation is to provide a foldable protective mask. The convex part is formed in the inner layer of the cover, so that the inner layer can be closely adhered along the bridge of the nose and the curve of the cheekbone, which can effectively fill the gap between the mask and the nose. Increase the tightness of the nose and improve the safety of the mask.

The second purpose of this creation is to provide a foldable protective mask. A convex part is formed on the upper folding part of the cover to prevent the exhaled mist from rising directly up through the cover and prevent the glasses from fogging.

The third purpose of this creation is to provide a foldable protective mask, in which a convex part is formed in the middle layer, so as to improve the filtering efficiency of the nose of the mask.

The fourth purpose of this creation is to provide a foldable protective mask. By providing an upper fixing part and a lower fixing part, and the lower fixing part is connected with one end of the upper fixing part, the opening size of the cover can be reduced, and the size of the opening of the cover can be reduced. When wearing, the internal space of the mask can be increased, so that it is comfortable to wear and does not stick to the mouth and nose, and does not stick to the lip mark, and the mask has a higher degree of tightness, which can effectively block germs and resist PM2.5.

In order to achieve the above objective, this creation is to provide a foldable protective mask, including a cover, including an upper fold, a main body, and a lower fold.
