Description

Mask and its plastic nose line improvement

The present invention relates to a mask, in particular to a mask and the improvement of its plastic nose line.

In recent years, the rapid development of industry and cities, various factories, coal-fired power plants, and large amounts of exhaust gas from steam and locomotives have caused serious air pollution, causing air quality to deteriorate day by day. The dust in the environment is fine suspended particulates (PM2). .5) Invade the human body through the respiratory tract and cause various diseases such as bronchitis, asthma and cardiovascular disease, 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 high blood pressure and diabetes, and even cause complications and lead to death.

Various bacterial 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 all killers of human health and are in and out of medical treatment. Hospitals or public places are also easy to infect each other, increasing the probability 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 their tightness in preventing epidemics and haze.

Generally, flat masks that are used in large numbers are mostly attached to the mouth and nose and the ventilation is concentrated in the mouth and nose, which increases the respiratory resistance and forces more air to leak from the gap. The labor research institute test confirmed the leakage The average rate is as high as about 33%, and the higher the leak rate of the mask, 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 nasal cords on the upper edge, such as plastic-coated iron cords. 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. For many years, most masks have iron wires installed in the nose line, which is neither economical nor environmentally friendly.

In view of this, one of the objectives of the present invention is to provide a mask and its plastic nose line improvement. The plastic nose line structure is made of polyethylene (PE), polypropylene (PP), polyurethane (PU), and polyvinyl chloride. PVC), thermoplastic polyurethane elastomer (TPU) or polyethylene terephthalate (PET) has the characteristics of elasticity and plasticity, and there is a hollow part in the nose segment, so that when wearing a mask, press the nose One side of the line segment can be plastically formed according to the curve of the nose, and the other side can generate natural elastic force to press the mask on the bridge of the nose and cheekbones, which greatly improves the tightness and comfort of the mask, and relatively greatly improves the protection efficiency and safety of the mask.

The second purpose of the present invention is to provide a mask and its plastic nose line improvement. The mask and nose line are made of plastic. After use, the mask does not need to remove the nose line and can be directly recycled, which saves labor costs, is economical and environmentally friendly. .

The third object of the present invention is to provide a mask and its plastic nose line improvement. The mask body is formed with horizontal and vertical folds. When unfolded into a solid shape, the mouth and nose space and the ventilation area can be enlarged, so that breathing is smooth, and speech Naturally, and greatly reduces respiratory resistance.

In order to achieve the above object, the present invention provides a mask, including: a mask body with an outer layer, at least one middle layer and an inner layer in sequence; and a plastic nose line structure arranged on the outer layer On; wherein, extending from the inner layer and folding out an inner layer folding piece, the inner layer folding piece and the outer layer jointly cover the plastic nose line structure.

Preferably, it further includes a pair of reversal sheets, which respectively extend from both sides of the mask body, and are fixed to the mask body at both ends after reversal.

Preferably, the mask body is formed with two longitudinal folds, which are respectively located on both sides of the plastic nose line structure.

Preferably, it further includes a pair of airtight sheets respectively covering both sides of the mask body, and both ends of which are fixed to the mask body.

Preferably, it further includes an exhalation valve installed in the mask body.

Preferably, the plastic nose line structure is respectively located at the upper part and the lower part of the mask body.

In order to achieve the above objective, the present invention provides a plastic nose line structure, which includes: a nose line segment; and a hollow part arranged in the nose line segment; the hollow part penetrates the nose line segment.

Preferably, it further includes at least one elastic support strip extending from the nose segment and located in the hollow portion.

Preferably, it further includes a notch, which is opened in the nasal line segment and communicates with the hollow portion, and the nasal line segment is formed with an upper bend and a lower bend located on both sides of the incision.
