Description

Mask and its plastic nose line improvement

This creation is about a mask, especially the improvement of a mask and its plastic nose line.

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 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 first, 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.

In view of this, one of the purposes of this creation 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, the nose is pressed 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 this creation is to provide a mask and its plastic nose line improvement. The mask and nose line material are made of plastic. After use, the mask does not need to remove the nose line and can be recycled directly, which saves labor costs, is economical and environmentally friendly. .

The third purpose of this creation 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 body shape, the mouth and nose space and ventilation area can be enlarged, so that breathing is smooth, and speech Naturally, and greatly reduces respiratory resistance.

In order to achieve the above objective, this creation provides a mask, which includes: 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; wherein, from the inner layer The layer extends and is folded back to form an inner layer folding piece, and 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, respectively located on both sides of the plastic nose line structure.

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

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

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

In order to achieve the above-mentioned purpose, 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.
