Description

A new type of daily protective mask

technical field

The invention relates to the technical field of masks, in particular to a novel daily protective mask.

Background technique

Mask is a kind of hygiene product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, odors, droplets, solid particles (fine dust, haze, pollen, etc.) from entering and leaving. Oral and nasal appliances; also used in medical and industrial settings.

People often wear masks for daily protection; however, traditional meltblown cloth masks and existing nuclear pore membrane masks have the following shortcomings:

1. The filter layer of the traditional melt-blown cloth mask is formed by the random accumulation of countless melt-blown fibers. On the microscopic view, its structure is formed by the irregular interphase distribution of several air holes and blind holes of different sizes;

For ordinary melt-blown cloth masks, because the selected melt-blown fibers are thicker and the number of stacks is small, the structure formed by the filter layer: fewer pores, large pore size, and although the air permeability is good, it is difficult to meet the filtration level;

For the better meltblown cloth masks of KN95 type, the meltblown fibers selected for the filter layer are thinner and the number of stacks is large, and the structure formed by the filter layer: many pores and small pore size, although the filtration level is high, the air permeability and comfort are high. not good.

Therefore, the disadvantages of melt-blown cloth masks are: the porosity and pore size cannot be guaranteed. Due to the influence of the processing technology, the quality of the melt-blown fiber filter material is not guaranteed, and the quality control is not easy to do. It is difficult to ensure the breathability and comfort of the mask at the same time. and filter level.

2. Ordinary nuclear pore membrane mask, the nuclear pore membrane that acts as a filter is a homogeneous membrane of polycarbonate irradiated by heavy ion beams to break the chemical bonds in the polymer, and then corrode to obtain cylindrical pores, and the pore size can be controlled at Membrane between 0.1-50um; this kind of mask structure: the pore porosity is very stable, the pore size is small and uniform, it has ultra-high filtration and air permeability, and it can be repeatedly sterilized and used without affecting the performance, which is a good solution to melt blown Problems with cloth masks.

However, the design of the pores of the existing nuclear pore membrane masks is basically a straight hole structure that runs vertically from the inner side of the mask to the outer side of the mask; when people talk to each other at close range, it is easy for the other party to carry virus droplets or fine particles in the air. Infect the human body directly through the air hole into the inside of the mask.

At the same time, both traditional meltblown cloth masks and existing nuclear pore membrane masks have a problem: the buffer space between the mouth and nose and the inner side of the mask is small, which leads to direct contact between the mouth and nose of the person when wearing the mask and the inner layer of the mask. If you use the mask for a long time, the inside of the mouth and nose will become wet, which will cause external bacteria and viruses to easily enter the inside of the mask to infect the human body, and the smell will be heavy, which will seriously affect the use effect.
