Description

Mask and its composite nose line

This creation is related to a mask, especially a mask and its composite nose line structure.

In recent years, the rapid development of industry and cities, various factories, coal-fired power plants, and a large number of steam and locomotive exhaust emissions have caused serious air pollution, leading to the deterioration of air quality. The dust in the environment is fine suspended particulates (PM2). .5) Invade 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 human carcinogen. Seven of the top ten cancer deaths in Taiwan are closely related to air pollution. Long-term inhalation of dirty air that has not been completely filtered by a mask can easily cause many cancers and diseases, such as chronic diseases such as hypertension and diabetes, and even cause complications and death.

Various bacteria, viruses and influenza in the living environment continue to invade humans, such as severe acute respiratory syndrome (SARS), avian influenza (H7N9), swine influenza (H1N1), Middle East respiratory syndrome (MERS), etc., which are killers of human health and are in and out of medical treatment. Hospitals or public places are also prone to mutual infection, increasing the chance of infection, showing that masks are increasingly important to human health. In particular, the new crown pneumonia (COVID-19) at the beginning of this year (2020) shocked the world. By the end of June, tens of millions of people had been diagnosed, and more than 500,000 people had died. The situation is very serious and it has been confirmed to be airborne. The importance of masks and tightness in epidemic prevention and haze prevention.

Generally, flat masks that are used in large numbers are mostly attached to the mouth and nose and concentrated in the mouth and nose, which increases the breathing resistance and forces more air to leak from the gap. The labor research institute test has confirmed that the leakage rate is as high as 33% on average. When the mask leaks The higher the rate, the more dangerous it is. This is a major defect of non-woven flat masks that have been difficult to improve over the past few decades.

The hot air exhaled from the body of the mask wearer can easily rise from the bridge of the nose and leak air, and fog up the glasses, affecting the line of sight, and even affecting the safety of driving and work. In addition, most common masks on the market have been equipped with various nasal lines on the upper edge, such as the nasal line that is usually covered with plastic and iron. When the mask is recycled, it is necessary to remove the iron wire from the mask body, and then classify the mask body and the iron wire, which is laborious, time-consuming, and labor cost. Over the years, most masks have iron wires in their nose lines, which is neither economical nor environmentally friendly. Another part is changed to plastic nose line, most of which are not well-shaped, and the plastic nose line lacks elasticity, which causes a lot of nose deflation and poor tightness, which greatly affects the safety of the mask.

In view of this, one of the purposes of this creation is to provide a mask and its composite nose line. Through the material of the composite nose line structure, polyethylene (PE), polypropylene (PP), polyurethane (PU), polyvinyl chloride (PVC) are selected. ), a combination of any two of thermoplastic polyurethane elastomer (TPU) or polyethylene terephthalate (PET), and the elastomer bridges the groove, which has the characteristics of good elasticity and easy plastic solidification. As a result, when wearing a mask, the pressing seat body can be plastically formed according to the curve of the nose, and the convex part can generate natural elastic force to press the mask to the bridge of the nose and cheekbones, which greatly improves the tightness and comfort of the mask, and relatively greatly improves the mask’s performance. Protection efficiency and safety.
