Safe rope-free mask

Abstract

The invention discloses a safe rope-free mask. The problems that an existing mask is inconvenient to wear and low in air pollutant filtering efficiency are solved. The safe rope-free mask comprises mask cloth, a mask nose clamp and a mask rubber ring. The mask cloth is used for covering the face contour of the human body and purifying air and comprises a primary filtering supporting layer, a nanofiltration layer and a protection layer which are sequentially overlapped together from outside to inside. The nanofiltration layer is of an interlayer structure and comprises two layers of nonfiber nets and micron fiber felt which is clamped between the two layers of nonfiber nets and manufactured by a chitosan solution through an electrostatic spinning process. The mask nose clamp is arranged at the upper end of the mask cloth. The mask rubber ring is arranged on the edge of the protection layer. The safe rope-free mask is convenient to wear, comfortable and safe, multi-layer structural design is adopted, then the characteristics of a chitosan material and the electrostatic spinning process are ingeniously combined, and therefore the filter effect of the mask on air pollutants is greatly optimized, and the effect of purifying the air is enhanced.

Description

technical field [0001] The invention relates to a mask, in particular to a safety cordless mask. Background technique [0002] In recent years, my country's air environmental burden has increased significantly, and PM2.5 has increasingly attracted public attention. The air contains a large number of pollutant particles, including dust of heavy metal ions, toxic chemicals, and some infectious microorganisms and viruses. [0003] At present, the masks worn in daily travel, such as commonly used non-woven masks, do not have the effect of anti-virus and sterilization. In addition, when wearing traditional masks, such as over-ear and over-the-head, the ears will bear a certain amount of tension. For people who wear glasses, wearing them for a long time will feel uncomfortable. In addition, for the common N95 masks on the market, there is a problem that the pressure drop is too large, and you will feel tired when you wear it for a long time. [0004] Therefore, it is necessary ...

[0003] At present, the masks worn in daily travel, such as commonly used non-woven masks, do not have the effect of anti-virus and sterilization

In addition, when wearing traditional masks, such as over-ear and over-the-head, the ears will bear a certain amount of tension. For people who wear glasses, wearing them for a long time will feel uncomfortable.

In addition, for the common N95 masks on the market, there is a problem that the pressure drop is too large, and you will feel tired when you wear it for a long time.
