Long-acting multifunctional protective mask

Abstract

The invention discloses a long-acting multifunctional protective mask. The mask comprises a mask body, fixing bands are arranged on the mask body, the mask body comprises a textile fabric outer layer,a filter element layer and a skin attaching layer, the textile fabric outer layer is fixedly connected with the filter element layer, the skin attaching layer is connected with the mask body, the filter element layer comprises a non-woven fabric layer and a melt-blown fabric layer, and a filter layer is arranged between the non-woven fabric layer and the melt-blown fabric layer. The long-acting multifunctional protective mask has the beneficial effects that the long-acting multifunctional protective mask has good filtering efficiency on particulate matters, can be used for a long time, has afiltering effect which is not easy to attenuate, and can kill bacteria and viruses and can prevent secondary pollution; peculiar smell and voc can be removed; the inner layer and the outer layer are made of textile fabrics, the skin-friendly inner layer is made of natural fibers, and the skin-friendly layer can be detached and washed, so that the mask used for a long time is kept clean.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a long-acting multifunctional protective mask. Background technique [0002] At present, the masks on the market have the following problems: [0003] 1. Ordinary masks with a filtration efficiency of less than 90% for bacteria or 0.3um particulate matter have unsatisfactory anti-virus and anti-pm2.5 effects; [0004] 2. Medical masks, KN ​​series masks, and daily protective masks with a filtration efficiency of more than 90% can only block droplets and aerosols, but cannot kill bacteria and viruses, so there are risks, and they are generally used for one-time use (just too wasteful) ), or after disinfection, but if the disinfection is not in place, there will be secondary hazards. At the same time, the skin layer of these masks is basically non-woven fabric (chemical fiber cloth), which does not absorb sweat, is prone to allergies, and has peculiar smell; The mask is made of tex...

AI Technical Summary

Problems solved by technology

[0003] 1. Ordinary masks with a filtration efficiency of less than 90% for bacteria or 0.3um particulate matter have unsatisfactory anti-virus and anti-pm2.5 effects;

[0004] 2. Medical masks, KN ​​series masks, and daily protective masks with a filtration efficiency of more than 90% can only block droplets and aerosols, but cannot kill bacteria and viruses, so there are risks, and they are generally used for one-time use (just too wasteful) ), or after disinfection, but if the disinfection is not in place, there will be secondary hazards. At the same time, the skin layer of these masks is basically non-woven fabric (chemical fiber cloth), which does not absorb sweat, is prone to allergies, and has peculiar smell; The mask is made of textile fabric, but most of the filter elements are melt-blown cloth, which is not suitable for washing, so even if the textile fabric is used, it is easy to get dirty, especially the skin layer, which is easy to be dipped in food, lipstick, Human body spraying, etc.; if the filter element is in the form of an insert (the filter element can be pulled out to clean the jacket), there will inevitably be gaps (air leakage) between the insert filter element and the mask jacket, so the protective effect cannot meet the national standard requirements at all, so this This structure is not desirable

In addition, most of the meltblown cloths on the market decay too fast, and within a few days, the filtration efficiency decays to less than 90%, and they cannot be used anymore. In addition, most of the masks on the market are used to protect against particulate matter. No protection against harmful gases such as voc;

[0005] 3. Although the new filter material that has just been launched on the market can be washed 10-20 times, the price is very high (about ten times that of melt-blown cloth in the normal period), and it is also very "delicate" and cannot be combined with activated carbon and other materials (membrane The surface is easy to wear and fail), so the function is too single
