Cylindrical shape or rectangular air cleaner cartridge
Technical field
The utility model belongs to the accessory of motor car engine, particularly a kind of cylindrical shape or rectangular air cleaner cartridge.
Background technique
In the process of engine running, need air, and contain impurity usually in the air, foreign matter such as dust and water vapor, air must purify earlier before entering motor, air cleaner cartridge filters air process before entering motor, removes foreign matter, guarantees the normal operation of motor.Filter core of the prior art is used the papery filter core always, the papery filter core, and it is little to filter body waterproofing effect difference and Air permenbility, and working life is too short and the recycling rate is low.
A kind of improved cylindric polyurethane air filter core is disclosed in the utility model patent of the patent No. 200720138401.9, its main structure comprises the inside and outside filter screen of tubular that concentric spacing is provided with, filter layer, upper end cap and lower end cap, described filter layer be polyurethane foam sheet make around the axis setting and extend vertically, and sidewall is provided with the annular official jargon structure of the fold that longitudinally distributes, and polyurethane foam sheet is ventilative micropore or microgap structure.The polyurethane foam sheet filter layer replaces the papery filter layer, ventilating performance and utilization ratio increase, but the polyurethane foam sheet shortcoming is to clean clean and bad drying in the cleaning back short time, cause water vapour to enter motor easily, in addition, the polyurethane foam sheet air-strainer is easily adhered to, stops up by clay contaminated.
Application number is that 201010189859.3 application for a patent for invention discloses a kind of PET non-woven fabric air filter element, its main structure comprises PET injection moulding upper end cap, PET terylene non-woven fabric body, PET injection moulding grid ring skeleton and PET injection moulding lower end cap, PET nonwovens body is that annular body, PET nonwovens body surround by the PET nonwovens is along the circumferential direction folding, its internal surface is fixedlyed connected with the outer surface of grid ring skeleton ...The sieve core callback that this PET nonwovens is made is the utilization ratio height again, good water-proof effect, Air permenbility is improved, but has following deficiency, 1, when PET nonwovens body be one the circle corrugationless the PET nonwovens time, filter area is little, deficiency of air, poor filtration effect; 2, when the PET nonwovens along the circumferential direction folds the ring structure that surrounds by the PET nonwovens, because nonwovens has the ductility of cloth, long when service time one, because the influence of air draught and adhesion impurity, adjacent PET nonwovens folding face can adsorb and bonds together, and air inflow and filtering effect are reduced greatly, and dirt is difficult for cleaning when cleaning simultaneously, air inflow is little, makes the motor can't proper functioning.
