Technical field
The utility model relates to the air-strainer that uses in the automobile, specifically is that a kind of can the reduction sucks automobile noise reduction air-strainer noise of air, that stability in use is good.
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, air communication is crossed filter cleaner and is produced bigger noise, and the air-filtering weak effect of air-strainer can not be removed totally for the dust of trace level at present, has influenced 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 provide a kind of can reduce inflow noise, be difficult for being badly shaken automobile noise reduction air-strainer that stability is high.
Technological scheme: in order to realize above purpose, a kind of air-strainer described in the utility model is made of loam cake, lower shell body and filter core; Loam cake is added a cover on lower shell body, and filter core is between loam cake and lower shell body;
Cover on described and be provided with the air outlet, the upper surface of loam cake is domatic; The air outlet is positioned at the most significant end of loam cake;
Described lower shell body lowermost end is provided with suction port, and suction port one side is provided with fixing column, and the fixing column end face is provided with a positioning hole; The lower shell body side is provided with groove; The design of groove makes the air-strainer motor of more fitting, and has effectively reduced taking up room of air-strainer, and the design that makes each parts in the automobile is compact and reasonable more;
Described lower shell body side also is provided with two locating points: first locating point and second locating point, and first locating point, second locating point and fixing column are with direct and firm being fixed on the motor car engine of air-strainer; Improved the stability in use of air-strainer.
Described filter core is made up of waveform filter paper and edge sealing; Edge sealing is positioned at the outside, waveform filter paper base, and filter core integral body in echelon.
In the utility model because filter paper filter efficiency height, the effective 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 core 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 edge sealing, and this edge sealing is fixed in filter core the inside of air filter for automobile.
In the utility model, in order further to reduce the noise of automobile noise reduction air-strainer described in the utility model, described filter core is provided with edge sealing, and it adopts the integrated method of thermoplastic that filter paper and edge sealing are fixed together; Because the edge sealing good springiness, effectively damping makes filter core can be good at being fixed between lower shell body and the loam cake, has improved the quality of product.
The first locating point center and edge distance D 1 are in the utility model: 62mm-63mm; The perpendicular distance D2 at the first locating point center and the second locating point center is: 104.5mm-105.5mm; Fixing column end face width D 3 is: 32.5mm-33.5mm; Fixing column end face length D4 is: 39.5mm-40.5mm; The internal diameter of fixing column end face positioning hole is 16.3mm-17.3mm.
Beneficial effect: a kind of air-strainer 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; Increase 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, the present invention is because the design of locating point with firm being fixed on the motor of the air-strainer under the present invention, has increased the stability when air-strainer uses.
