Abstract
The invention discloses an anti-microbial mask filter element for effectively filtering out PM2.5 particulate matter. Compared with common filter elements and masks, the filter element is of a three-layer structure, an outer layer is a bamboo fiber meltblown non-woven fabric where a zinc phthalocyanine light-sensitive material attaches to, a middle layer is a polarized meltblown non-woven fabric, and an inner layer is a polypropylene spunbonded non-woven fabric. The anti-microbial mask filter element can effectively filter out the PM2.5 particulate matter, effectively kill bacteria and prevent secondary pollution and is uvioresistant. In addition, the filter element can adhere to the inner layers of a stereoscopic mask, a disposable mask and other types of masks through movable adhesive tape colloidal particles, can be combined with other common masks in use and is simple and practical in operation.
Description
Technical field
The invention belongs to health care category, particularly relate to a kind of antibacterial and effectively filter the mouth mask filter disc of PM2.5 particle.
Background technology
Mouth mask is a kind of healthy prevention articles for use that are widely used in various occasions, mouth mask main function components is filter disc, filter disc is on the market mainly the filter disc of filtering function, filter filter disc can blocks air in PM2.5 particle, but the particle being filtered and bacterium are just easily attached to the position of pressing close to mouth and nose on mouth mask (filter disc), cause growing of bacterium, form secondary pollution, penetrate into human body by mouth mask (filter disc) again, human body is worked the mischief, do not meet the requirement of health, reduced protection, the antibacterial effect of mouth mask yet.The bactericidal mask existing on market can not effectively filter out PM2.5 particle, and particle can carry bacterium and enter human respiratory, kills bacterium process long (be generally 18 hours or more than, killing rate is greater than 70%) simultaneously.So far, not yet fundamentally solve filter disc is filtered combine with antibacterial functions, sterilization process grows and the secondary pollution problems of mouth mask.
Summary of the invention
The object of the invention overcomes the secondary pollution problems of the long and mouth mask of the single filtering function of filter disc, sterilization process, effectively in conjunction with filtering function and the antibacterial functions of filter disc, provides a kind of effectively antibacterial and filter the mouth mask filter disc of PM2.5 particle.
Brief description of the drawings
Fig. 1 is mouth mask and filter disc schematic diagram
for realizing object of the present invention, the present invention has adopted following technical scheme:
The filter disc of the present application adopts the melt spraying non-woven fabrics of processing in polarization method, make melt spraying non-woven fabrics with static, on the basis of original mechanical filter, increase Electrostatic Absorption filtering function, effectively improve filter effect, reduce filtration resistance, can filter 0.3 micron of fine particle, filter efficiency reaches 95%-99%.
The application's invention filter disc adopts photodynamics sterilizing, and photodynamics sterilized principle for germ is that bacterium is killed in sensitising agent generation dynamic response under the exciting of suitable wavelength light.Sensitising agent is accepted natural light irradiation, absorbs the energy of photon, and photochemical reaction occurs, and produces free state or singlet oxygen and kills bacterium.The application's invention filter disc adopts natural light irradiation sensitising agent, can avoid directly adopting side effect human body being brought near the wavelength of ultra-violet (UV) band.
The filter disc of the present application adopts the melt-blown layer of cloth of bamboo fibre that adheres to phthalocyanines light-sensitive material, phthalocyanines light-sensitive material is under illumination condition, produce free state or singlet oxygen, can kill superbacteria, common pathogen (is included but not limited to gold-coloured staphylococci, Escherichia coli and candida albicans) 15 minutes within-1 hour, reach eradicative rate 70%-99%, short more a lot of than general antibacterial mask sterilization process, can avoid the secondary pollution of bacterium.Phthalocyanines light-sensitive material is as catalyst simultaneously, and along with time lengthening, sterilization effect can not weaken, and can reuse one week, compared with disposable breathing mask, favourable to environmental protection.
The melt-blown layer of cloth primary raw material of bamboo fibre that the filter disc of the present application adopts is bamboo fibre, and uvioresistant efficiency reaches 99.4-99.8%, can effectively avoid the damage of ultraviolet ray for skin of face.
The filter disc of the present application adopts the upper filter disc of micelle adhesion, and operation is simple and feasible, and safety and environmental protection can not cause the residual of micelle, and use in this way can combine this filter disc with dissimilar filter face mask.
