Abstract

This creation is to provide a mask, which includes a filter formed by a nanofiber film layer in the body of the mask. The filter can filter dust and infection sources such as PM2.5, and the nanofiber film layer The pores are small and the porosity is high. In addition to being able to attach more dust and infection sources, breathing can be very smooth during use.

Description

Masks

This creation is about a mask, especially a mask with filtering dust.

Due to the vigorous development of industry and the concentration of population, the exhaust gas emitted from factories and automobiles and locomotives has become the number one killer of human health, especially the extremely small particles (such as PM2.5) in the exhaust gas, which is one of the important causes of various cancers. The population is over-centralized and urbanized, and various infectious diseases have become a nightmare that people can't wait to avoid. When infectious diseases prevail and the air is dirty, the first way people think of is to wear masks. Therefore, masks have become Essential personal necessities.

However, ordinary masks on the market can only filter larger particles of dust and larger sources of infectious diseases, and it cannot be stopped for smaller sources of infectious diseases and very small dust (such as PM2.5). Although more professional masks (such as N95 masks) can filter smaller sources of infectious diseases and very small dust, but their breathability is not good, so users have difficulty breathing and are criticized, so it is necessary to improve. This is the main subject of this case.

This creation is to provide a mask, which includes a mask body and a filter screen. The filter screen is arranged on the mask body, and the filter screen includes a mesh body and a filter. A nanofiber film layer attached to the outer surface of the mesh body. The nanofiber film layer has a plurality of pores.

In the above mask, wherein the mask body includes an outer layer and an inner layer, there is a sandwich space between the outer layer and the inner layer, and the filter net is placed in the sandwich space.

In the above mask, an opening is provided in the mask body, and the interlayer space opens to the outside through the opening.

In the above mask, the opening is provided in the inner layer of the mask body.

The mask described above, wherein the net system is composed of metal wires.

In the above mask, the nanofiber film layer mainly uses a high voltage to electrolyze the surface of the nanofiber and is fixed on the mesh body by electrostatic force.

This creation uses the extremely fine pores and high pore density between fibers in the nanofiber film layer, which has a higher porosity, and has more pore surface area, which can attach smaller and more infections. Source or particulate dust, so its filtering effect is good. In addition, although the pore size is small, the porosity is high, so the breathing is smoother and the use is more comfortable.

In order to allow your reviewers to have a better understanding of the characteristics and features of this creation, the following preferred embodiments are listed and illustrated in conjunction with the drawings as follows: Please refer to Figures 1 to 4 for a preferred embodiment of this creation A provided mask 100 includes a mask body 10 and a filter 30. The filter 30 is assembled in the mask body 10.

Please refer to FIG. 1 to FIG. 4. In one embodiment, the filter 30 includes a mesh body 31 and a nanofiber film layer 32 adjacent to the outer surface of the mesh body 31. The mesh body 31 is composed of A plurality of metals are warp and weft flat woven, and have a flat mesh body with fine meshes. The nanofiber film layer 32 is laid on the inner and outer surfaces of the mesh body 31 by electric board textile technology, and then the polymer solution is passed through high pressure to generate nano The rice particles are electrolyzed on the surface of the nanofibers and are fixed on the mesh body 31 by electrostatic force. The nanofiber film layer 32 has a plurality of extremely fine three-dimensional pores and high pore density between the fibers. That is, higher porosity and more surface area of pores.

In one embodiment, the mask body 10 includes an outer layer 11 and an inner layer 12, and ear hooks 16 are provided on both sides of the mask body 10, and the outer layer 11 The outer layer 11 has the same shape and size as the inner layer 12, and is sewn on the periphery. There is a sandwich space 13 between the outer layer 11 and the inner layer 12, and the filter 30 is placed in the sandwich space 13. Please refer to FIGS. 5 to 6. In another embodiment, a mask 100 provided is the same as the first embodiment, and also includes a mask body 10 and a filter 30 and other structures and features. The mask body 10 is provided with an opening 14 through which the mezzanine space 13 can be opened to the outside. Therefore, the filter 30 can be put into or withdrawn from the opening 14. The opening 14 of this embodiment is provided on one side of the inner layer 12, and the filter 30 is placed in the sandwich space 13 of the inlet cover body 10 from the side, and can also be taken out from the side opening 14. Please refer to FIG. 7 to FIG. 8. In another embodiment, a mask 100 provided is the same as the first embodiment, and also includes a mask body 10 and a filter 30, which are different in structure and features. The shape of the inner layer 12 is different from that of the outer layer 11. The inner layer 12 is smaller than the outer layer 11. The opening 14 is located near the middle of the inner layer 12, and the filter 30 is placed from the middle of the mask body 10. In or out.

Please refer to Fig. 9. Fig. 9 is the use state diagram of this creation. The user 90 can put the ear hook 16 on the ear 91, and the mask body 10 covers the mouth and nose. 10 in and out, and filtered through the filter 30 therein. Due to the small pores and high porosity of the nanofiber film layer 32 in the filter 30 of this creation, in addition to filtering smaller dust (such as PM2.5) and infection Outside the source, the surface area between them can be large enough to attach more dust and infection sources, and its porosity is high, so it can breathe smoothly and is very practical.

The above disclosure is only the preferred embodiment provided by this creation, and is not intended to limit the scope of implementation of this creation. Any equal change in the relevant artisans in this technical field according to this creation shall belong to this creation. Coverage.
