FIG. 1 is a schematic view of the antibacterial and antiviral mask of the present invention;

description of reference numerals: 1-antibacterial and antiviral filter layer, 2-melt-blown cloth layer, 3-antibacterial and antiviral fiber layer, and 4-skin-friendly layer.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, but the technical solution does not limit the scope of the present invention.

Referring to fig. 1, the present embodiment provides an antibacterial and antiviral mask, including a melt-blown fabric layer 2, an antibacterial and antiviral filter layer 1 is disposed on the outer side of the melt-blown fabric layer 2, and an antibacterial and antiviral fiber layer 3 and a skin-friendly layer 4 are sequentially disposed on the inner side of the melt-blown fabric layer 2; the antibacterial and antiviral filter layer 1 is used for killing viruses and bacteria in the inhaled air, the melt-blown cloth layer 2 adsorbs the viruses and bacteria in the inhaled air through electrostatic action, and the antibacterial and antiviral fiber layer 3 is used for killing the viruses and bacteria in the exhaled air and killing trace bacteria and viruses permeating from the melt-blown cloth layer 2 in the inhaled air. In practice: the virus meets the antibacterial and antiviral filter layer 1 in the process of flying the droplets in the air, the antibacterial and antiviral filter layer 1 can block the droplets for the first time and kill the virus and bacteria in the droplets, part of the virus or bacteria can pass through the antibacterial and antiviral filter layer 1, at the moment, the virus or bacteria adsorbed on the melt-blown cloth layer 2 can be killed by the antibacterial and antiviral filter layer 1 for the second time, meanwhile, a trace of bacteria or virus can pass through the melt-blown cloth layer 2, and at the moment, the antibacterial and antiviral fiber layer 3 kills the trace of bacteria and virus, so that the virus and bacteria in the inhaled air are killed for three times, and the situation that a human body inhales the virus or bacteria and is infected is prevented; when the wearer is infected, the exhaled air can carry viruses and bacteria, and at the moment, the bacteria and the viruses in the exhaled air can be effectively killed by the antibacterial and antiviral fiber layer 3, so that the infection of other people is prevented; the skin-friendly layer 4 has the functions of improving the comfort of a wearer, reducing skin irritation and preventing moisture.

Specifically, the antibacterial and antiviral filter layer 1 is an antibacterial and antiviral cotton cloth layer. The antibacterial and antiviral filter layer 1 and the antibacterial and antiviral fiber layer 3 are respectively prepared by a preparation method in the Chinese invention patent ZL201310190451.1, namely a method for preparing and immobilizing metal nanoparticles on a substrate and an application thereof on the basis of a cotton cloth material and a fiber material. More specifically, the material of the antibacterial and antiviral filter layer 1 was a nano silver cotton textile prepared in example 4 of the embodiment of the above patent. The material of the antibacterial and antiviral fiber layer 3 is nano silver cellulose prepared in example 3 of the embodiment of the above patent. Of course, it is also possible that the antibacterial and antiviral filter layer 1 is made of other materials having the same antivirus function, and it is also possible that the antibacterial and antiviral fiber layer 3 is made of other materials having the same antivirus function.

Specifically, the meltblown layer 2 also serves to prevent droplets, which have already been mentioned above, from being blocked for the first time by the antibacterial and antiviral filter layer 1, but some droplets may pass through the antibacterial and antiviral filter layer 1, so that the meltblown layer 2 blocks droplets for the second time to improve the filtering ability of the inhaled air. The antibacterial and antiviral filter layer 1, the melt-blown cloth layer 2, the antibacterial and antiviral fiber layer 3 and the skin-friendly layer 4 are sequentially and tightly attached to form a cover body so as to enhance the capability of killing bacteria and viruses. The left side and the right side of the cover body are respectively provided with an ear belt so as to be convenient for wearing. The upper side of the mask body is provided with a metal belt which is used for clamping the mask body on the nose bridge of the human face. The cover body is provided with three folds to reduce the storage volume, and the number of the folds can be four or other numbers with the same function. The skin-friendly layer 4 is a non-woven fabric skin-friendly layer, and can be other skin-friendly layers with the same function. It should be noted that, the utility model discloses an antibiotic antiviral filter layer 1 of antibiotic antiviral gauze mask and antibiotic antiviral fibrous layer 3's material is all preferred cotton cloth material or the fiber material that can repeatedly implement the function of disinfecting that disinfects, consequently, the utility model discloses an antibiotic antiviral gauze mask is not disposable, but can used repeatedly many times, and this waste of resource has also been avoided, the cost is reduced. Certainly, the utility model discloses an antibiotic antiviral gauze mask structure also can be used to make disposable gauze mask, be about to antibiotic antiviral gauze mask's antibiotic antiviral filter layer 1 and antibiotic antiviral fibrous layer 3's material replacement for once only disinfect the virus killing material can.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
