Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, 2, this novel automobile air-conditioner filter core, comprise framework 1 and the filter core 2 that is arranged at framework 1 inside, described filter core 2 is set to pre-filtering layer, filter sterilization layer from outside to inside and removes knoisphere, described pre-filtering layer adopts active carbon polyurethane to filter foam, described filter sterilization layer adopts nano-silver nonwoven cloth, and described except knoisphere employing thin layer superfine fibre, the folding spacing of described three layers of Combination filter element 2 is set to 1.5-2.5cm.
Described pre-filtering layer adopts active carbon polyurethane to filter foam, and the polyurethane that namely adds active carbon filters foam.Active carbon is mainly used in air cleaning, organic solvent recovery, sewage disposal, health care, protective clothes, electronics and energy field and corrosion-resistant and high temperature resistant place.Activated carbon has good adsorption capacity to organic gas and odorant (as normal-butyl mercaptan etc.), inorganic gas.Microorganism and bacterium are also had to good adsorption capacity (as reached 94-99% to colibacillary adsorption rate), good especially to the adsorption capacity of low concentration adsorbate.
Polyurethane filters foam and through perforate membrane removal, has formed the network structure of main body framework, the voidage of this screen pack cotton exceeds 97%, and percent opening reaches 99%, has good gas permeability and higher mechanical strength, therefore as filtering material, there is flow resistance little, leach the feature that efficiency is high.And can repeatedly wash, show the advantages such as durable, economy, environmental protection.Be mainly used in filter, the filter course of air-conditioner, the carrier of ceramic foam filter in aquarium.
Described filter sterilization layer adopts nanometer silver antimicrobial nonwoven, and the metals such as mercury, silver, copper, zinc, titanium, lead all have antibacterial ability.Wherein the antibacterial ability of silver is only second to mercury, and safety non-toxic.When silver-colored particle diameter reaches nanoscale and becomes Nano Silver, owing to presenting skin effect and quantum effect, its anti-microbial property will increase to thousands of times.Nano Silver size ratio bacterium (hundreds of nanometer) below 25nm, virus (tens nanometer) also little.Thereby it can be combined for the base enzyme of breathing with them by penetration cell wall, bacterium, virus are choked to death, do not leave the possibility that changes gene.So nanometer silver antimicrobial is quick-acting, wide spectrum, have no drug resistance.Nonwoven is as a kind of medically conventional protective materials, and its anti-microbial property is good.At present, the technology of producing nanometer silver antimicrobial nonwoven is ripe, and it has the extremely strong sterilizing ability not possessing than common cloth, can resist more than 40 kind of pathogenic germs such as killing staphylococcus aureus, fungi, mould, Pseudomonas aeruginosa.Nanometer silver antimicrobial nonwoven is widely used in medical mask, protective garment, barrier gown, medical sheet, sanitary napkin, paper diaper, diaper etc., reliable to human body touch-safe, have have no side effect, the advantage such as nonirritant, insensitivity, asepsis environment-protecting.Thereby the material using nano-silver nonwoven cloth as automobile air conditioner filter element, can be effectively antibacterial, purifies air.
Described except knoisphere employing thin layer superfine fibre, generally fiber number 0.3 μ m(diameter 5 μ m) following fiber calls superfine fibre, superfine fibre can adsorb dust, particle, the liquid of 7 times of own wts, every filament only has 1/200 of hair, superfine fibre body space is many, surface area is very big, makes fabric have extremely strong cleaning action, can effectively stop fine dust and pellet such as PM2.5.
Outermost layer active carbon polyurethane of the present utility model filters foam and directly contacts with car outer air, play pre-filtered effect, can tentatively tackle and in air, be greater than the dust particle of 5um and eliminate peculiar smell, and go deep into the nexine of filter core when air, can be subject to the further dedusting of filter sterilization and the super-fine fiber material of nanometer silver antimicrobial nonwoven, effectively tackle more tiny dust, through filtering layer by layer, final air into the car will become totally pure and fresh, healthy harmless.
Specifically, the burden of filtered air dust can be effectively shared in the pre-filtering of active carbon polyurethane filtration foam, and the superfine fibre of nexine is only responsible for the filtration to minute dust, reduced the amount of dust that material surface is assembled, effectively delay obstruction speed and extended service life of product.
For guarantee can to ventilate smoothly in dedusting, the utility model is changed the folding spacing that air conditioner filter element was fine and closely woven in the past, replaces the folding spacing that 1.5-2.5cm is comparatively loose.As everyone knows, in the situation that filter core appearance and size is certain, the folding spacing of filter core is less, and the filtrate area of filter core will increase, and filtering velocity reduces, and in certain size range, its filter efficiency can increase, and filtration resistance can reduce, and dust containing capacity also will increase.But along with folding the reducing of spacing, gas channel reduces, increased air-flow mobile energy loss in air flue, increased the product structure resistance of filter.By three layer filtration, realized the expection of dust-collection sterilization, loose folding spacing has reduced the structural resistance of product, has increased ventilation.
Nanometer silver antimicrobial nonwoven has the extremely strong sterilizing ability not possessing than common cloth, can resist more than 40 kind of pathogenic germs such as killing staphylococcus aureus, fungi, mould, Pseudomonas aeruginosa.Air more into the car, can greatly reduce airborne bacterium after nano-silver nonwoven cloth filters, and eliminate the hidden danger that threatens car owner's health, antibacterial for a long time, and assurance air is into the car clean, safety.
