Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.

The first embodiment is as follows: as shown in fig. 1 and 2, the high-efficiency filtering mask comprises a mask body, wherein two ends of the mask body are provided with ear hooks. The ear-hang can be set with different wearing modes according to different using environments, and can be in a rope type, an elastic type and the like. The ear hook may be set to a fixed length or an adjustable length. The ear-hang of this embodiment adopts the elasticity formula of adjustable length, and its ear-hang itself adopts the rope that has certain elasticity to make, is equipped with length adjustment on the ear-hang and detains for adjust the length of mouth ear-hang 7, in order to increase the travelling comfort that the gauze mask was worn.

The mask body is formed by stacking four layers of structures from outside to inside (the inner layer is attached to the face), and sequentially comprises a textile layer, a blocking layer, a filtering layer and a skin-friendly layer. The textile layer is made of polyester fiber fabric, and is good in air permeability, firm and durable.

The barrier layer is an Edison anti-mite fabric which has a honeycomb-shaped internal fiber structure, and the porous structure has anti-mite and dustproof performances, and can filter most of particulate matters, dust and mites to play a role in preliminary filtration. Meanwhile, the fabric has good air permeability, can be drained quickly, and keeps the fabric surface dry and comfortable.

The filter layer is a polytetrafluoroethylene microporous membrane, and one side of the polytetrafluoroethylene microporous membrane is provided with a non-woven fabric. The polytetrafluoroethylene microporous membrane is in a net structure formed by the staggered arrangement of polytetrafluoroethylene nano fibers, the diameter of the fibers is less than 100nm, the formed net structure can well filter microorganisms, viruses, dust and the like, is light, thin and breathable, and has the characteristic of high blocking efficiency. The filter is physically filtered, the filter efficiency cannot be reduced due to static loss when the filter is stored for a long time like a melt-blown cloth mask, and the service life is long.

The skin-friendly layer is a regenerated cellulose fiber textile fabric, the moisture absorption and the air permeability of the fabric are better than those of natural cotton fibers, the fabric is soft in hand feeling, and the comfort of the inner side of the mask is high.

In order to improve travelling comfort, stability and the parcel effect of reinforcing gauze mask that the gauze mask was worn, the back is tailor by a surface fabric to the gauze mask body, and outside bellied V-arrangement portion in the middle of sewing up the formation is sewed up at upper and lower both ends, and upper and lower both ends adduction forms three-dimensional modeling wholly, makes the gauze mask wear the back and forms certain space with oronasal department, does benefit to and breathes, laminates facial simultaneously all around.

Example two: as shown in fig. 1 and 2, the high-efficiency filtering mask comprises a mask body, wherein two ends of the mask body are provided with ear hooks. The ear-hang of this embodiment adopts direct hangers formula, and the stretch cord that both ends all fixed on the gauze mask is respectively established to gauze mask both sides promptly, directly when wearing with the stretch cord hang on the ear can, wear the convenience.

The filter layer is a polytetrafluoroethylene microporous membrane, and both sides of the polytetrafluoroethylene microporous membrane are provided with non-woven fabrics. The polytetrafluoroethylene microporous membrane is in a net structure formed by the staggered arrangement of polytetrafluoroethylene nano fibers, the diameter of the fibers is less than 100nm, the formed net structure can well filter microorganisms, viruses, dust and the like, is light, thin and breathable, and has the characteristic of high blocking efficiency. The filter is physically filtered, the filter efficiency cannot be reduced due to static loss when the filter is stored for a long time like a melt-blown cloth mask, and the service life is long.

The skin-friendly layer is a moisture-absorbing and sweat-releasing fabric, the moisture-absorbing and sweat-releasing fabric is a fabric with antibacterial, deodorant, moisture-absorbing and sweat-releasing properties obtained after a common fabric is treated by an auxiliary agent, for example, a nylon, chinlon or terylene fabric is treated by an FC-226 Si high-cleanness moisture-absorbing, sweat-releasing and soil-releasing protective agent to obtain the fabric with the moisture-absorbing, sweat-releasing and soil-releasing properties.

The cover body of the high-efficiency filter mask is provided with a textile layer, a blocking layer, a filter layer and a skin-friendly layer, wherein the blocking layer is made of an Edison anti-mite fabric which has a honeycomb internal fiber structure, and a porous structure has anti-mite and dustproof performances; the filtering layer is a polytetrafluoroethylene microporous membrane, and a reticular structure formed by stacking nano-scale fibers can well filter microorganisms, viruses, dust and the like, and is light, thin and breathable. This gauze mask possesses the efficient characteristics of separation, owing to rely on the physics to filter, deposits for a long time and also can not reduce filtration efficiency because of losing static like melt-blown cloth gauze mask, long service life. The four-layer structure can be cleaned and can be cleaned for repeated use only in dust prevention. When used for preventing virus and bacteria, the disinfectant such as alcohol can be used for disinfection or used for many times after high-temperature disinfection.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
