Along with the global continuous spread of new crown epidemic situation, epidemic prevention becomes a normal demand, the problems of waste pollution, incapability of being reused and the like caused by the disposable epidemic prevention medical mask formed by the common melt-blown fabric and the non-woven fabric are urgently needed to be solved, and people need a mask which can be reused, is fashionable and attractive, meets social and heavy occasions, and has an anti-virus function.

The common disposable mask is roughly divided into three layers, wherein the inner surface layer and the outer surface layer are both non-woven fabrics, the middle layer is melt-blown fabric, and the melt-blown fabric is utilized to filter air. The melt-blown fabric is treated by an electret process to generate an electrostatic effect, and particles can be adsorbed and intercepted. However, the mask of the electrostatic adsorption type has a disadvantage that the mask is not always in a state of charge saturation after static electricity is added, and the static electricity content in the non-woven fabric layer is gradually reduced in each link of mask production, packaging, delivery, transportation, and then the mask is opened for use by a consumer, and the attenuation of the static electricity inevitably causes the reduction of the protective efficiency of the mask of the melt-blown non-woven fabric. In addition, as the wearing time increases (e.g., after one to two hours), the mask becomes damp due to moisture in the wearer's breath, the electrostatic adsorption capacity thereof is reduced, and the isolation effect gradually deteriorates. Therefore, the melt-blown cloth filter mask has lower use reliability and durability and poorer protection effect. In addition, the conventional disposable mask has the following problems:

1. due to the use of the non-woven fabric surface layer, patterns cannot be printed, the colors are uniform, the repeated feeling of one side of a thousand people is given to people, and image problems are brought to solemn outcrossing occasions and social places;

2. the production process problem is that the pressing fit plane structure is not adapted according to the face shape, so that the edge and the human body structure cannot be tightly fitted;

3. the melt-blown cloth filter material is used, the aperture of the filter hole is large, and the filter material cannot be used repeatedly.

Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.

The first embodiment is as follows: as shown in fig. 1 and 2, the present embodiment provides a civil nanometer customized respirator with epidemic prevention function, which includes a respirator body 1 and ear hanging belts 2, wherein the ear hanging belts 2 are respectively disposed at two ends of the respirator body 1, and is characterized in that the respirator body 1 is made of multiple layers of materials, and includes an outer surface layer 3, a flow guiding layer, a filter layer 5 and an inner surface layer 6, the flow guiding layer is used for moisture absorption and sweat release, and the flow guiding layer and the filter layer 5 are disposed between the outer surface layer 3 and the inner surface layer 6.

In this embodiment, the flow guide layer includes a first flow guide layer 40 and a second flow guide layer 41, the filter layer 5 is disposed between the first flow guide layer 40 and the second flow guide layer 41, the first flow guide layer 40 is disposed adjacent to the outer surface layer 3, and the second flow guide layer 41 is disposed adjacent to the inner surface layer 6. To this end, the mask body 1 is composed of the outer surface layer 3, the first flow guide layer 40, the filter layer 5, the second flow guide layer 41 and the inner surface layer 6 in sequence from outside to inside. In the embodiment, five layers of materials are adopted, a three-dimensional cutting process is adopted, and the mask is attached to the outline of the face, so that the mask is full and attractive when being worn, the air leakage of edge gaps is reduced, the effect of increasing protection is achieved, and the mask can be folded and stored and is convenient to carry. Of course, in order to reduce the air resistance, one of the flow guide layers may be reduced, and four layers of nano materials are adopted, which will be understood by those skilled in the art.
