Description
Technical field
The air-strainer that the present invention relates to use in the automobile specifically is a kind of air purification effect of both having played, and can reduce the automobile noise reduction air-strainer of the noise that sucks the air generation 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, and this resonant body so just causes the bulky of whole air-strainer between suction tude and housing, unfavorable installation; Because automobile is subjected to the strong frequent vibrations of jolting easily in traveling process, air-strainer also is given a shock again, is connected the vibrations that are subjected to jolting of resonant body between suction tude and the housing and is easy to damage, need frequently replacing, increased the user cost of automobile.
Summary of the invention
Goal of the invention:, the invention provides and a kind ofly can reduce automobile noise reduction air-strainer inflow noise, that be difficult for being badly shaken, that the filtered air ability is strong in order to solve the deficiencies in the prior art.
Technological scheme: in order to realize above purpose, a kind of automobile noise reduction air-strainer of the present invention comprises housing, filter core and cap; The lid cap is above housing; Filter core is between housing and cap;
The main body of described housing is divided into three chambeies: air resonance chamber, airflow cyclotron cavity and gas exhaust chamber; Also be provided with suction port and air outlet on the described housing; Suction port links to each other with the air resonance chamber; The air outlet links to each other with the gas exhaust chamber; Because the air resonance chamber has replaced original air resonance body, air resonance body and air-strainer are combined together, be equivalent to the air resonance body has been put into the housing of air-strainer, reduced the overall volume of air-strainer, easy for installation, saved the space.
Described filter core is made of filter, gas channeling piece and exhaust port; Filter is positioned at the top of airflow cyclotron cavity; The gas channeling piece is positioned at the top in air resonance chamber; Exhaust port is corresponding with the air outlet; The air installation certain orientation that will suck in the air-strainer that is provided with of gas channeling piece imports in the airflow cyclotron cavity fast; In the prior art, the air that enters air-strainer produces strong vibrations and noise in a jumble because of direction, because direction of air is mixed and disorderly, is subjected to force direction inconsistent simultaneously, has reduced the air total amount by air-strainer, has reduced the working efficiency of air-strainer; Among the present invention, is (which type of guide pad wanted clearly to adopt the gas channeling piece?) after, the air that enters air-strainer changes the air-flow traffic direction through the gas channeling piece, make air-flow enter airflow cyclotron cavity fast, reduced the time of air-flow in the air-strainer internal flow, improve the air total amount of the air-strainer of flowing through in the relative time, strengthened the working efficiency of air-strainer.
Cap described in the present invention covers above filter core, forms the gas stream cavity between filter core and the cap.
In order better to play the effect of filtered air, the filter of described filter core is wavy among the present invention; And the filter of described filter core adopts filter paper to make.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, improved simultaneously the whole endurance strength of filter again, can not cause breakage, improve serviceability, service time and the quality of product of product because not bearing the air strong wallop; Moreover because filter paper itself has the effect of absorption of noise, the filter element filtering body that adopts filter paper to make among the present invention can effectively reduce air and enter the noise that air-strainer produces; The working life of air filter for automobile and the quality of product have been improved.
Among the present invention, the chamber wall of the airflow cyclotron cavity in the described housing is provided with the stiffening rib and the gas channeling piece that circles round, the acting as of the stiffening rib and the gas channeling piece setting of circling round among the present invention: the intensity that 1, increases air filtering device structure; 2, gas is carried out water conservancy diversion, reduce the output of air-strainer internal gas flow fine jade, promptly reduce the mutual collision of air-flow.
Equally in order better to improve the working efficiency of automobile noise reduction air-strainer of the present invention, the inwall of described cap is provided with stiffening rib, the fast flow speed and direction of the guiding air outlet of the air of the gas stream cavity between filter core and the cap of flowing through stiffening rib on the cap.
Among the present invention, in order further to reduce the noise of automobile noise reduction air-strainer of the present invention, the filter edge of described filter core is provided with the rubber frame, and wherein filter and rubber frame can adopt the integrated method of thermoplastic to be fixed together; Because rubber frame good springiness, effectively damping, sealing make filter core can be good at being fixed between housing and the cap, have improved the quality of product.
For automobile noise reduction air-strainer is fixedly installed on the motor, also be provided with three location and installation holes on the described housing among the present invention: the first location and installation hole, the second location and installation hole and the 3rd location and installation hole;
Horizontal equivalent A is between first center, location and installation hole and the center, the second location and installation hole: 144.4mm-145.6mm;
Perpendicular distance B between first center, location and installation hole and the center, the second location and installation hole is: 131.4mm-132.6mm;
Perpendicular distance C is between first center, location and installation hole and the center, the 3rd location and installation hole: 311.7mm-314.3mm;
Perpendicular distance D is between first center, location and installation hole and the air outlet hole center: 224.1mm-225.9mm.
Among the present invention on the filter core axial width E of gas channeling piece be 84.31mm, the height F be 23.5mm.
Beneficial effect: a kind of automobile noise reduction air-strainer provided by the invention, compared with prior art, advantage of the present invention is:
1, owing among the present invention, the air resonance chamber is arranged in the housing, dwindles the volume of whole air-strainer, simplified the structure of air-strainer, prolonged working life, be easier to installation and maintenance.
2, make owing to the filter in the filter core among the present invention adopts filter paper, effectively reduced the noise of air-strainer, improved ability, the efficient of air-strainer filtered air.
3, since among the present invention because the stiffening rib that all adds in housing and the cap has been made guiding to the flow direction of air, alleviate the vibrations that cause because suck a large amount of air, strengthened working efficiency, the minimizing system resistance of air-strainer.
4,, effectively played effect shockproof, sealing owing to the application of nonwovens among the present invention and rubber frame.
