As an embodiment, a repeatedly usable gauze mask, including gauze mask body and removable filter, its characterized in that, the gauze mask body is annular frame construction, and both ends symmetry is provided with the gauze mask fixed band about the gauze mask body, and the center department of gauze mask body is provided with the fretwork filtration mouth, and the outside edge of fretwork filtration mouth is provided with the magic subsides, and removable filter is located the centre of fretwork filtration mouth.

Please refer to fig. 1 to 6, as an embodiment of the present invention, a reusable mask, comprising a mask body and a replaceable filter, characterized in that the mask body is of an annular frame structure, the mask body is symmetrically provided with mask fixing bands at the left and right ends, the center of the mask body is provided with a hollow filter, the outer edge of the hollow filter is provided with a magic tape, and the replaceable filter is located in the middle of the hollow filter.

Referring to fig. 1 to 5, optionally, the mask body is a reusable structure, and is mainly divided into a mask body as a structural support and a replaceable filter element with a filtering effect, the mask body is an annular frame structure, a hollow filtering port with a hollow structure is arranged in the middle of the mask body, the inner side edge of the replaceable filter disc is correspondingly provided with a magic tape, the replaceable filter disc and the hollow filter ports can be connected through the magic tape, the size of the replaceable filter disc and the hollow filter ports are mutually matched, therefore, the whole mask can be recycled by replacing the replaceable filter disc, the reusability of the mask is convenient to improve, the replacement is more convenient, and the inboard edge of gauze mask body is provided with the attached silica gel area of annular, and the attached silica gel of annular takes shape and human nostril and mouth looks adaptation, and human face of laminating when being convenient for wear wears more comfortablely and is favorable to improving the seal and the filtration efficiency of gauze mask.

Referring to fig. 1 to 6, optionally, the mask mainly filters air passing through the hollow filter through a replaceable filter, the replaceable filter is an independent structure for cleaning and replacement, the replaceable filter is composed of a three-layer cloth structure, the three-layer cloth structure includes a polypropylene protective outer layer, a biomass fiber filter layer, a halamine antibacterial textile layer, a polypropylene protective outer layer at the outermost side, the polypropylene protective outer layer is made of polypropylene, the surface of the polypropylene protective outer layer has a certain gap through which air can pass, and at the same time, the surface of the biomass fiber filter layer has a certain waterproof type and can protect the internal material, the biomass fiber filter layer is located between the polypropylene protective outer layer and the halamine antibacterial textile layer, so the inner side of the polypropylene protective outer layer is a biomass fiber filter layer, the biomass fiber filter layer has the same structure as the melt-blown cloth, and the fiber diameter of the biomass fiber filter layer can reach 1, the filter layer of the biomass fiber is a blend fiber of a copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate and polylactic acid, and is different from common melt-blown cloth which takes polypropylene as a main material, the bacteriostasis rate of the blend fiber to staphylococcus aureus, streptococcus, escherichia coli and the like reaches 99%, meanwhile, the fiber product has good moisture absorption and air permeability, the wearing safety and comfort of the novel mask are effectively improved, meanwhile, the copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate and polylactic acid are degradable materials, compared with polypropylene, the fiber product is more environment-friendly, the innermost halamine antibacterial textile layer directly contacts with a human body, the halamine antibacterial textile layer is a polypropylene material which is subjected to surface grafting treatment of a hydroxyhalamine compound, the hydroxyl halamine compound is 1, 3-dimethylol-5, 5-dimethylhydantoin, and a polypropylene material subjected to surface grafting treatment of the hydroxyl halamine compound is woven into a finished product, wherein the contained hydroxyl halamine compound can kill most common germs such as staphylococcus, escherichia coli, pseudomonas aeruginosa and the like in a short time and also has a killing effect on some viruses, so that the problem that the inside of a mask is polluted and cannot be reused due to the fact that bacteria generated by breathing remain on the surface of a fabric by using common non-woven fabrics is solved, in the process of killing the bacteria and the viruses, oxidized halogen atoms are consumed to cause that N-X bonds in halamine molecules are converted into N-H bonds to lose activity, but after the product is simply rinsed by a bleaching solution with a dilute concentration, namely a hypochlorite solution, the N-H bond can be oxidized into the N-Cl bond to obtain the sterilization function again, so that the replaceable filter disc can be reused after being simply rinsed by bleaching liquid, namely hypochlorite solution, and is matched with the detachable structure to play a role in repeated use, and meanwhile, the edges of the three-layer cloth-shaped structure are sealed by ultrasonic pressing, so that the tightness and the filtering efficiency of the whole structure are kept.

When in use, the mask body can be fixed on the face through the mask fixing belts symmetrically arranged on two sides, so that the annular adhesive silica gel belt at the edge of the mask body is attached to the face to keep the tightness of the mask body, air enters the mask from the outside through the hollow filter openings, the replaceable filter disc arranged at the hollow filter openings can filter the air, the mask can be worn and used, when the replaceable filter disc needs to be replaced for a period of time, the whole mask can be taken down firstly, then the replaceable filter disc is taken down from the hollow filter openings, then a new replaceable filter disc is fixed at the hollow filter openings through the magic tapes correspondingly arranged, the replacement work of the replaceable filter disc is completed, the replaced replaceable filter disc can be simply rinsed in bleaching liquid with very low concentration, namely hypochlorite solution, so as to keep the activity of hydroxyl halamine compounds in the halamine antibacterial textile layer, therefore, the antibacterial effect of the whole replaceable filter disc is maintained again, and the replaceable filter disc can be repeatedly used.

The utility model provides a reusable mask, through set up fretwork filtration mouth in the middle of the mask body of frame nature structure, and the mask mainly filters the air through removable filter element, removable filter element then can paste in fretwork filtration mouth department through magic subsides structure, thereby block up the fretwork filtration mouth completely and filter, also be convenient for simultaneously dismantle, installation and change, and removable filter element inside is provided with biomass fiber filter layer and halamine antibiotic textile layer, can play the effect of filtration and sterilization, and biomass fiber filter layer mainly is made by the fibre that PHBV/PLA blending formed, for degradable material, use more environmental protection, and halamine antibiotic textile layer is made for the natural cotton fiber through the processing of hydroxyl halamine compound, can effectively kill all kinds of bacterial virus, can resume bactericidal performance through ordinary antiseptic solution processing simultaneously with used repeatedly, so as to improve the overall repeated utilization rate of the mask.

Those of ordinary skill in the art will understand that: the discussion of any embodiment above is meant to be exemplary only, and is not intended to intimate that the scope of the disclosure, including the claims, is limited to these examples; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
