Protective mask for placed nose pads

This creation relates to a mask, and in particular to a protective mask for a placed nose pad.

In recent years, the rapid development of industry and cities, exhaust emissions from various factories, coal-fired power plants and a large number of steam and locomotives have caused serious air pollution, resulting in deteriorating air quality. Dust mites in the environment are fine aerosols (PM2). .5) Invading the human body through the respiratory tract, causing various diseases such as bronchitis, asthma and cardiovascular diseases, which seriously endanger human health. At the same time, in 2013, the World Health Organization (WHO) confirmed that air pollution is the main carcinogen of human beings. Among the top ten cancer deaths in Taiwan, seven are closely related to air pollution. In addition, various bacterial viruses and influenza in the living environment have been invading humans in recent years, such as severe acute respiratory syndrome (SARS), avian flu, and swine flu (H1N1). It is the killer of human health, showing that masks are increasingly important to human health.

At present, the use of various protective masks in the world has reached tens of billions, of which about eight have become flat non-woven masks. The common flat masks on the market and even some N95 series dust masks are easy to carry and cheap, but the adhesion is generally poor. . According to the test method of Taiwan standard CNS14774 and 14755 protective mask (N95/FFP2) D2 tightness, the mask should be worn to achieve a tightness of 100 (100% ÷ 100 tightness = 1% air leak rate), but according to Taiwan's labor safety and health The Institute's 100-person test, the marketed two N95 masks have an average fit of 13.9 and 21.8, while the average flat mask average is only 3.10, which means the average air leak rate is 33%, resulting in the effect of dust mites (PM2.5). Great discount. In order to maintain a certain degree of tightness, the current general masks have been installed with plastic nose lines on the upper edge, such as plastic strips or plastic coated iron wire or aluminum strips to increase the tightness to prevent the gap between the nose and the face. . However, due to the shape, size and height of the nose of the mask, the most easily leaked is also the most difficult to prevent leakage. When the nose is pressed by hand, it will be slightly conformed and shaped. After wearing for a few minutes, it will still be worn. Due to the slight facial muscle activity, there are large gaps, especially the masks are supported by elastic ear straps or straps on both sides to make the air pollutants and virus bacteria easy to "get into the air" for many years. The fatal flaw of the mask.

Long-term inhalation without masking completely dirty air can cause many cancers and diseases, such as chronic diseases such as hypertension and diabetes, and even cause complications and death. When entering or leaving a medical institution or public place, it is easy to infect each other and increase the chance of infection. . Because most of the masks are worn, most of them are attached to the nose and mouth, and the air is concentrated in the mouth and nose. This increases the respiratory resistance and forces more air to leak from the gap. This causes the general leakage rate to be as high as 40%. The leakage rate of the mask is more. The higher the time, the more dangerous it is. This is a large defect in the non-woven flat mask that has been difficult to improve significantly in the past few years.

Moreover, the hot air exhaled by the mask wearer from the body will also rise upward from the bridge of the nose, causing the glasses to fog, affecting the line of sight, and even affecting the safety of driving. There are also masks for installing nose bridge foam on the market. Because the foam has a certain thickness and is placed between the mask and the nose bridge, the foam and the sides are still prone to voids, so that the mask can not effectively fit the face shape, greatly reducing the nasal airtightness. effect.

In view of this, one of the purposes of the present invention is to provide a protective mask for a placed nose pad. By forming a convex portion on the upper edge of the mask body, the inner layer can be closely adhered along the bridge of the nose and the tibia, effectively filling The gap between the mask and the nose greatly increases the tightness of the nose.

The second purpose of the present invention is to provide a protective mask for a placed nose pad, which is formed with horizontal and longitudinal wrinkles on the mask body, and when the shape is formed, the mouth and nose space and the ventilation area can be enlarged to make the breathing smooth. The speech is natural and greatly reduces respiratory resistance.

The third purpose of the present invention is to provide a protective mask for a placed nose pad, wherein a convex portion is formed on the upper edge of the mask body, and the convex portion can fill the gap between the nose bridge and the tibia to block the exhalation of the mist from passing through the mask. The body (10) rises directly upwards to prevent the glasses from fogging.

In order to achieve the above object, the present invention provides a protective mask for a built-in nose pad, comprising a mask body, an outer layer, a middle layer and an inner layer; and a nose pad disposed on the outer layer; An inner layer fold is extended from the inner layer and folded back, the inner layer fold member and the outer layer jointly cover the nose pad, and a convex portion is formed on the mask body corresponding to the nose pad.
