[0029]

[0030] ​The sealing adjusting mechanism is symmetrically arranged outside both sides of the mask main body, and is provided with a magic tape and three bending grooves.

[0031] The bending grooves include a first bending groove 10, a second bending groove 11 and a third bending groove 12.

[0032] The first bending groove 10 is horizontally arranged at the middle of the mask main body, and the second and third bending grooves are symmetrically and obliquely arranged at both sides of the first bending groove 10.

[0033] The first and second bending grooves are provided with a magic tape A face 13, and the first and third bending grooves are provided with a magic tape B face 14.

[0034] The upper part of the mask main body is provided with a nose clip 15 arranged in the foldable iron sheet or iron wire in the interlayer.

[0035] The working principle of the utility model is: when air passes through each protective layer, first, it is blocked and killed by the copper ion layer, then passes through the zinc ion containing layer, has bacteriostatic effect, then passes through the non-woven fabric layer composed of silver ion and polypropylene, then passes through the melt-blown cloth layer, and finally passes through the non-woven fabric layer of the veneer part into the mouth and nose.

[0036] When the acetate fiber is used, 145mg / 1000mL of copper nano (1-100nm) is added, and the copper ion has a strong inhibitory effect on bacteria and viruses.

[0037] The sterilization mechanism of copper can be applied in many fields, including the medical field, the application in medical environment, copper preparation has good hematopoietic function, is an essential trace element for human body, and has no harm after being absorbed by human body. The copper absorbed by human body surface is consistent with the daily necessary intake of human body. In the field of building, it is applied to anticorrosive preparation, such as paint, which is mixed with 13-40 mg / L of copper (nanometer level). In the field of food processing, copper is a non-toxic material, food is not easy to spoil in copper dishes, even if a small amount is absorbed by human body, it is harmless, and the smaller the size, the better, and the small size is particularly prominent in copper element, and the antibacterial performance is as follows:

[0038] Nanometer copper oxide > elemental copper oxide > elemental copper > various copper salts > copper salt.

[0039] Sterilization mechanism and application of zinc: through the ion exchange of zinc ions and bacterial cells, the abnormality of enzymes and other protein mechanisms in bacterial cells is caused, so as to destroy the biological membrane and metabolic basis of bacteria and viruses, and the result of inhibiting and killing bacteria and viruses is achieved. Zinc ions can affect the replication (DNA replication) and transcription of bacteria and viruses, and hinder their growth and reproduction. This biological effect is used in medical treatment, preservation and other aspects, and is cheap.

[0040] In the present technology, the size of zinc ions is refined to nanometer level (1-100 nm), and the specific surface area is as high as 20 m 2 / g-35 m 2 / g per square meter, only 0.1-0.2 g of the textile is used per square meter to achieve the most satisfactory sterilization effect.

[0041] The sterilization effect of silver has a long history in China, such as tableware and protective supplies. With the passage of time, professional institutions realize that although silver has a certain bactericidal effect, when silver ions are in close contact with the skin, they can indeed enter the body through the skin capillaries. The present process uses large particle silver particles and non-toxic chemical fiber material to produce a new type of silver-containing fiber cloth through hot melt spraying. The silver particles in the fiber cloth have a size of 100 nm-500 nm, which not only maintains the large specific surface area of silver, but also prevents the size from being too small to enter the human body through the human body surface.

[0042] The specific surface area of high-purity silver nanometer powder prepared by anodic arc discharge plasma method is 23.8 m 2 / g, and the present process uses silver particles with a specific surface area of 1-10 m 2 / g to make non-woven fabric with polypropylene. The mask made of silver-containing non-woven fabric is arranged between the third layer and the first layer (the surface outer layer) of the mask, the moisture in the gas reflected by the human body is fully combined with the silver ions, and the sterilization capacity is stronger under the action of water.

[0043] Silver ions can rely on the Coulomb force firmly adsorbed on the bacterial cell membrane, destroy the peptidoglycan structure of the cell wall, cause the cell to rupture, and the cell membrane to flow out, leading to the death of the bacteria. Silver ions gather on the surface of the bacteria, affect the permeability of the bacterial membrane, destroy the electron transport system and material transport system of the microorganism, and lead to the inability of the bacteria to metabolize and reproduce.

[0044] Silver ions and DNA interaction: silver ions can block ATP production, destroy DNA replication, produce reactive oxygen species (ROS), bind to DNA molecules double helix, replace hydrogen in the DNA molecule double helix structure, cause DNA molecule structure to change, inhibit DNA, RNA and protein binding, and synthesis, leading to the death of the bacteria. When the air microorganisms adhere to the mask, they are killed after being entangled by silver ions under the action of non-woven fabric fibers and silver particles. The product has good anti-bacterial and viral effects, even the mutated bacteria and viruses will lose activity under the action of silver ions, so that the product has good epidemic prevention function.
