Abstract
The utility model provides a respirator for preventing PM (particulate matter) 2.5, which mainly aims at the problem that the existing respirator does not has the functions of PM2.5 dust particle prevention and sterilization. The respirator for preventing PM2.5 comprises outer layer material, filtering layer material and inner layer material, has high filtering efficiency on micrometer, submicron and nanometer suspended particulate and neutral particulate in the air, has virus killing effect on bacteria adhered to dust and spread with the air, and prevents bodies from being damaged by air pollution.
Description
Technical field
The utility model provides a kind of protective mask, relates in particular to a kind ofly anti-can go into lung particle mouth mask by what electret filtering layer material was processed, belongs to healthy prevention articles for use field.
Background technology
PM2.5 is meant that diameter is less than or equal to 2.5 microns particle in the atmosphere, is also referred to as and can goes into the lung particle.At present, because industrial pollution, domestic pollution, motor vehicle exhaust emission, a large amount of suspended particulate that floats in the air, one, tier 2 cities or industry concentrates high city and the area of car owning amount, a large amount of suspension serious harm health in the air.For preventing air pollution, the general employing worn the mouth mask protection, but used mouth mask is that diameter is less than or equal to 2.5 microns suspended particulate substance and does not have protection effect in the air to PM2.5, does not also have the virus killing sterilizing function.
Summary of the invention
For solving existing the problems referred to above that exist with protective mask, the utility model provides a kind of protective mask with PM2.5 suspended particulate and virus killing sterilizing function in the blocks air that adopts that electret filtering layer material and continuous cloth material make.
The technical scheme that the utility model technical solution problem is taked is; Anti-can go into lung particle mouth mask body and process by fluoroplastics electret filtering layer material and continuous cloth material, comprise mouth mask inner layer material, mouth mask cladding material and be arranged on internal layer and skin between fluoroplastics electret filtering layer material.
Described electret is to materials such as fluoroplastics, and under effect of factors such as strong external electric field, polarization also can the longer-term storage electric charge.In the fluoroplastics electret, there is electrostatic field; The numerous similar numerous passive collecting electrode of nanoscale hole on the material; When airborne micron, sub-micron or nanoscale suspended particulate, be blocked in outside the filtering layer during with air through these holes, under the effect of electric field force, be hunted down; Airborne neutral corpuscle becomes dipole because of induction or polarization through the electret filtering layer time, also effectively stopped and catch.
Bacterial virus has natural electret state (electronegative), and being attached to usually on the suspended particulate flows with air propagates, when they are stopped or catch and can't get in the body with air by electret filtering layer material together with suspended particulate during through electret filtering layer material.The electrostatic field of electret filtering layer material production and little electric current can damage the cell membrane of bacterial virus, destroy the surface texture of bacterial virus, stimulate the protein variations of bacterial virus, cause bacterial virus dead.
Described fluoroplastics are the composite of polytetrafluoroethylene (PTFE), perfluoro second propylene (FEP), ethylene-tetrafluoroethylene copolymer (ETFE) or polytetrafluoroethylene (PTFE) and perfluoro ethene (FEP).
Described fluoroplastics electret filtering layer material is porous crack thin-film material or the porous crack sponge material of being processed into by above-mentioned fluoroplastics; Adopt electret technical finesses such as corona method or puncture method; Make it become electret, the diameter of described thin-film material or sponge material hole is a nanoscale.
Described fluorine plastic film or sponge electret are provided with numerous nanoscale holes; Its good air-flow property is arranged, have low flow resistance, dustproof sterilization efficacy, excellent characteristic is arranged aspect purifying air; But also have acidproof, alkaline-resisting, high temperature resistant; Water insoluble and alcohol equal solvent, nontoxic, the characteristics that performance is safe and reliable.
The beneficial effect of the utility model is; Has excellent dustproof and virus killing sterilization efficacy; Filter efficiency to airborne micron, sub-micron or nanoscale suspended particulate and neutral corpuscle is high, can stop that the PM2.5 suspended particulate gets in the body with air, and is extremely strong with airborne bacterial virus insect killing effect to being attached on the suspended particulate; And air resistance is about 236Pa, is adapted at wearing under the air ambient that PM2.5 exceeds standard.
Description of drawings
Fig. 1 can go into lung particle Respirator structure sketch map for the utility model is anti-.
Fig. 2 can go into lung particle press mold mouth mask sketch map for the utility model is anti-.
Among the figure, 1 mouth mask body, 2 cladding materials, 3 filtering layer materials, 4 inner layer materials, 5 sutures, 6 frenulums.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment is further specified.
Embodiment 2; As shown in Figure 1; The utility model is anti-can go into lung particle mouth mask body (1) by cladding material (2), and filtering layer material (3), inner layer material (4) constitute, and cladding material (2), inner layer material (4) adopt fibrous materials such as cotton; Filtering layer material (3) adopts fluoroplastics electret sponge material; After according to design style and specification fibrous material such as skin, internal layer cotton and fluoroplastics electret sponge material being cut out, bead cover body (1) encircles limit machine suture (5) and is processed into, and mouth mask body (1) both sides are provided with respectively wears frenulum (6).
The embodiment that real the utility model provides is exemplary embodiments, does not limit the practical range of the utility model, allly relates to the principle that the utility model discloses, and the variation of material, distortion, replacement all belong to the rights protection scope of the utility model.
Claims (3)
1. anti-can go into lung particle mouth mask for one kind, it is characterized in that, comprise mouth mask inner layer material, mouth mask cladding material and be arranged on internal layer and skin between fluoroplastics electret filtering layer material.
2. according to claim 1ly anti-can go into lung particle cover, it is characterized in that fluoroplastics electret filtering layer material is porous crack thin-film material, the porous crack sponge material of being processed into by fluoroplastics.
