Description

Mask and composite nose line thereof

Technical Field

The invention relates to a mask, in particular to a mask and a composite nose line thereof.

Background

In recent years, due to rapid development of industry and cities, exhaust gas discharged from various factories, coal-fired power plants and a large number of automobiles and locomotives causes serious air pollution, so that the air quality is gradually deteriorated, dust haze in the environment, namely fine suspended particles (PM 2.5) invade a human body through a respiratory tract, various diseases such as bronchitis, asthma, cardiovascular diseases and the like are caused, and the health of the human body is seriously damaged. Meanwhile, the World Health Organization (WHO) in 2013 proves that air pollution is a main carcinogenic factor of human beings, and seven of ten cancer causes of death in the Taiwan area of China are closely related to air pollution. The long-term inhalation of dirty air which is not completely filtered by the mask is easy to cause various cancers and diseases, such as chronic diseases such as hypertension, diabetes and the like, and even to cause complications and death.

Various bacteria, viruses and flu in the living environment continuously attack human beings, such as Severe Acute Respiratory Syndrome (SARS), avian influenza (H7N 9), swine influenza (H1N 1), respiratory syndrome (MERS) and the like, are killers of human health, are easy to be infected when people go in and out of medical institutions or public places, improve the infection probability, and show that the mask is increasingly important to the human health.

When a large number of common plane masks are worn, the mask is mostly attached to the mouth and the nose for ventilation and is concentrated at the mouth and the nose, so that the breathing resistance is increased, more air is forced to leak from gaps, the average leakage rate is up to about 33% as proved by tests of a labor research institute, and the mask is more dangerous when the leakage rate is higher. This is a big drawback of the non-woven (or non-woven) flat mask which is difficult to improve for decades.

The hot air exhaled by the mask wearer is easy to jump upwards from the bridge of the nose to leak air, and the glasses are fogged, which affects the sight and even the safety of driving and working. In addition, various nose lines are usually installed on the upper edge of the common mask in the market, such as the nose line usually used for plastic-coated iron wire. During this gauze mask recovery processing, need follow earlier and demolish the iron wire from the gauze mask body, again with gauze mask body and iron wire classification, hard waste time, increase the cost of labor. And most of the mask nose lines are provided with iron wires for many years, so that the mask nose lines are not economical and environment-friendly. In addition, a part of the mask is changed into a plastic nose line, most of the mask is not good in shape, and the plastic nose line is lack of elasticity, so that a large amount of nose portions leak air, the sealing degree is not good, and the safety of the mask is influenced greatly.
