Abstract
The utility model discloses a filter element of an automobile air filter, which comprises a filtering body, a filter element windshield piece and an exhaust hole, wherein the filtering body is connected with the filter element windshield piece in parallel; and the exhaust hole is positioned in the filter element windshield piece. A filter paper is used as the filtering body, and the filtering area is enlarged due to a folding wave shape, so that the service time of the automobile air filter is prolonged, the air noise is reduced, and the service life of an engine is effectively prolonged.
Description
Technical field
The utility model relates to the air-strainer accessory that uses in the automobile, specifically is a kind of engine charge air purification effect of both having played, and can reduce the automobile noise reduction air cleaner cartridge that sucks noise of air again.
Background technique
Motor car engine produces power by the burning of gasoline and air mixing, need suck the auxiliary gasoline combustion of a large amount of air during motor car engine work.Because the circumstance complication of automobilism, often motor has sucked a large amount of impurity when sucking air.The existence of impurity can cause a series of problems in the air: airborne impurity enters in the machine oil of motor, has influenced the purity of machine oil, causes the heavy wear of motor; If impurity is excessive, then might stop up and might stop up the engine air throttle valve body, cause engine operation not smooth, even cause whole motor damage to work.Therefore, air must filter before entering motor.
The air-strainer of automobile use at present is because the suction air is large-minded, and air communication is crossed filter cleaner and produced bigger noise.In order to reduce noise, existing air-strainer all has the harmonic shock body, acting in conjunction by air filter housing and harmonic shock body is filtered air, but can not well remove for airborne minute impurities, still affect the purity of machine oil in the motor, accelerate the rate of wear of motor, reduced the working life of motor.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the utility model provides a kind of automotive air cleaner core, and this filter core can improve the purity that enters air in the motor, the reduction inflow noise, antidetonation.
Technological scheme: in order to realize above purpose, a kind of automotive air cleaner core described in the utility model comprises: filter, filter core blinker and relief opening; Filter and filter core blinker are tied together; Relief opening is positioned at the filter core blinker.
As preferred version of the present utility model, filter adopts filter paper to make in the filter core; Filter paper is waveform in the filter, and the number of folds of filter paper is 75-81; The effective filtration area of waveform filter paper is 8600CM
2
Because filter paper filter efficiency height, the effectively airborne impurity of filtering; Again owing to filter undulate in the filter core, increased the effective area of contact of filter core, further improved the ability of the clean air of filter, moreover because filter paper itself has the effect of absorption of noise, the filter element filtering body that adopts filter paper to make can effectively reduce air and enter the noise that air-strainer produces; The working life of automotive air cleaner core and the quality of product have been improved.
The outside of filter described in the utility model is provided with frame.This frame is fixed in filter core the inside of air filter for automobile.
In order to strengthen the fastness that is connected of frame and filter, frame described in the utility model adopts the PU material to make, and frame and filter thermosetting are together, a thermoset forming.
The filter core blinker is provided with stiffening rib in the utility model, has increased the intensity of structure.
The length overall A length of automotive air cleaner core described in the utility model is 375.1mm～372.1mm; Beam overall B is 192.6mm～190.6mm; It is 31.5mm～32.5mm that frame top filter exposes height C; Frame height D is 10mm～11mm; The length E of filter is 194.6mm～196.6mm; The overall width of filter is consistent with the overall width of filter core.The filter core blinker back side forms radian, and radius of the radian R is 250mm.
The mouth wall thickness of relief opening is 2.5mm in the utility model; The relief opening upper surface is the inclined-plane, horizontal by 25 ° of angles; The external diameter of relief opening is 76.2mm to the maximum, and minimum is 63.14mm.
Beneficial effect: a kind of automotive air cleaner core that the utility model provides compared with prior art, the utility model has the advantages that:
1, automotive air cleaner core described in the utility model is owing to adopt filter paper as filter; The turbidity test of air after the filtration of air filter for automobile have been strengthened; Strengthen filter area, effectively prolonged the working life of motor; Increase filter area by folding waveform simultaneously, increased the service time of air filter for automobile.
2, automotive air cleaner core described in the utility model leads to air owing to adopted the filter core blinker, reduces the output of air-strainer internal gas flow fine jade, promptly reduces the mutual collision of air-flow; The intensity that the increase air cleaner cartridge is set of stiffening rib on the while filter core blinker.
