Description

A New Airtight Protective Mask

technical field

The utility model relates to a mask, in particular to a new airtight protective mask.

Background technique

In recent years, with the rapid development of industry and cities, various factories, coal-fired power plants, and a large number of steam and locomotive emissions have caused serious air pollution. Dust haze (fine suspended particles PM2.5), pollen, and dust in the environment , into the human body through the respiratory tract, can cause various diseases such as allergies, asthma or colds, sneezing, runny nose, etc., resulting in a decline in human immunity, causing various diseases, and seriously affecting human health. In particular, the WHO (World Health Organization) announced in 2013 that seven of the top ten causes of death in the world are closely related to air pollution, which has prompted countries around the world to intensify anti-smog efforts, and at the same time caused most people to wear various types of masks. The WHO even released a report on October 29, 2018, pointing out that about 93% of the world, equivalent to 1.8 billion children under the age of 15, are exposed to poisonous air pollution, shocking all walks of life.

In view of the serious health hazards of dust and haze PM2.5, China and Taiwan formulated and announced national standards for anti-smog masks in 2016/2017 based on US-standard N95 series and European-standard FFP and other dust masks. However, according to the test method of D2 tightness of CNS14774 and 14755 protective masks (N95/FFP) in Taiwan, China, the tightness of the mask must reach 100. However, according to the test of 100 people from the Taiwan Labor Research Institute (Institute of Labor Safety and Health), the city The average tightness of the two N95 masks sold is 13.9 and 21.8, while the average of the general flat surgical mask is only 3.10, that is, the air leakage rate is 32.3% (that is, the tightness is 67.7%), which is the bacterial filtration efficiency (BFE) Only 67.7%. Usually, if the BFE 99% of a medical mask is tested with the N95 standard, that is, the wind speed test is replaced by 85L instead of 32L, the efficiency of filtering dust haze (PM2.5) is only about 60%, and the overall protective effect is about 40.6% including the air leakage rate. Due to the progress of production technology in the past ten years, the salt mist filtration efficiency of N95 dust masks can reach more than 99%. However, high-quality masks also need to have the characteristics of good adhesion and low pressure difference. However, the pressure difference (respiratory resistance) of the general N95 series masks is quite high, which is not suitable for long-term wear, especially for the three groups, such as children. , pregnant women, and people with weak lung diseases, even if the dust haze is severe and needs to be worn, they are not suitable for wearing.

In addition, in recent years, various bacterial viruses and influenza in the living environment have continuously invaded humans, such as severe acute respiratory syndrome (SARS), bird flu (H7N9), swine flu (H1N1), etc., which are all killers of human health. Masks with good fit and low pressure difference are extremely important for the maintenance of human health.

As shown in Figure 23, the patent document of patent publication number TW201526945A discloses a mask A3, which includes a mask body A10 and ear hooks A12 formed at both ends of the mask body A10 in the transverse direction, and is formed with a plurality of strips. Shaped creases A14, a plurality of strip-shaped creases A14 are fixed by welded parts A22 formed by heat sealing, welded parts A22 are formed at equal intervals on both sides in the transverse direction of the mask body A10 and in the longitudinal direction of the mask body A10 It is linear, and the distance between adjacent welded portions A22 is 3 mm (millimeters) or more. Both ends in the lateral direction of the mask body A10 are covered by side straps A30, and the ear hooks A12 are attached to the side straps A30. The lateral ends of the mask body A10 in contact with the side of the wearer's face are provided with side blocks A32 covering the gap between the face and the mask body A10. The side block A32 is formed by sandwiching one end of the wide band-shaped side insulating tape A31 between the mask body A10 and the side belt A30, so that the side of the mask body A10 is well attached to the face and can be restrained from the mask body. A gap is created between the A10 and the face to prevent the intrusion of fine particles into the mask.

In the above-mentioned published patent, the forming of the mask side block A32 is to first weld the upper and lower ends of the side insulating tape 31 with the first grid seal A17 and the second grid seal A24 and fix them on the upper and lower sides of the mask body A10, Then wrap the side insulation tape A31 and the mask body A10 side with the side tape A30 and weld it to complete. Therefore, its forming steps are many and the manufacturing process is complicated; in addition, the mode of covering the side insulating tape A31 and the mask body A10 side with the side tape A30 will also cause waste of mask raw materials and increase of production cost.
