Abstract
The utility model discloses an automotive air filter assembly, comprising an upper shell (1), a lower shell (2), an air filter air inlet pipe (3) and an air filter air outlet (4), wherein the air filter air inlet pipe (3) is connected to the lower shell (2), the air filter air outlet (4) is connected to the upper shell (1), the air filter air inlet pipe (3) extends into the lower shell (2), an inner insertion pipe (5) which is over against the air filter air outlet (4) is arranged in the upper shell (1), and one end, far away from the air filter air outlet (4), of the inner insertion pipe (5) is provided with an expansion port. Due to the adoption of the structure, the air inlet efficiency of the air filter is improved, the air inlet noise is reduced, and air current is smoother.
Description
Technical field
The utility model relates to auto parts and components---and the structure of air filter assembly, belongs to mechanical structure technical field.
Background technique
As shown in Figure 1, the air filter assembly that is applicable to automobile is mainly comprised of upper shell 1, lower shell body 2, air filter suction tude 3 and air filter air outlet 4, and upper shell 1 snaps together and forms air filter housing with lower shell body 2, and filter core 7 is housed in air filter housing.In air filter suction tude 3, be also provided with resonant cavity 6, play the effect of damping noise reduction.
Air filter suction tude 3 is connected on lower shell body 2, is provided with over against the suction port of air filter suction tude 3 on lower shell body 2, and air stream suction tude 3 is connected on suction port, and flushes with the inwall of lower shell body 2.Air filter air outlet 4 is arranged on upper shell 1, for connecting air filter steam outlet pipe (not shown).
Ambient air flows into from air filter suction tude 3, by lower shell body 2, upper shell 1, and finally 4 outflows from air filter air outlet.
The subject matter that this structure exists is: the air turbulence in air filter housing, and intake efficiency is undesirable, and inflow noise is bigger than normal.
Model utility content
The utility model is intended to improve the intake efficiency of air filter, reduces inflow noise, makes air-flow more smooth and easy.
For this reason, the technological scheme that the utility model adopts is: a kind of air filter assembly that is applicable to automobile, comprise upper shell (1), lower shell body (2), air filter suction tude (3) and air filter air outlet (4), described air filter suction tude (3) is connected on lower shell body (2), air filter air outlet (4) is arranged on upper shell (1), key is: described air filter suction tude (3) extends in lower shell body (2), in described upper shell (1), be provided with an interpolation pipe over against air filter air outlet (4) (5), described interpolation pipe (5) away from the one end of air filter air outlet (4) with extension mouth.
Be preferably, the length that described air filter suction tude (3) extends in lower shell body (2) is 1/3 of air filter lower shell body (2) width, the length of described interpolation pipe (5) is 1/3 of upper and lower casing (1,2) height sum, further to improve the air inlet effect of air filter.
The beneficial effects of the utility model:
(1) air filter suction tude extends in lower shell body, changed the divergence ratio that flows into air in air filter inner chamber, effectively reduced the noise of this position, the air inlet resistance that simultaneously makes to flow in air filter inner chamber is less, the smoothness of air-flow increases, and intake efficiency improves;
(2) in upper shell, set up an interpolation pipe with extension mouth, guiding airflow smooth ground, from air filter inner chamber inflow engine suction tude, prevents the generation of eddy current effectively, and the improvement of the smooth-going and noise of air-flow is had to remarkable result.
Accompanying drawing explanation

Fig. 2 is the structural representation after improving.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The air filter assembly that is applicable to automobile as shown in Figure 2, is mainly comprised of upper shell 1, lower shell body 2, air filter suction tude 3 and air filter air outlet 4, is also provided with resonant cavity 6 in air filter suction tude 3.Upper shell 1, lower shell body 2, resonant cavity 6 are working of plastics, and air filter suction tude 3 is rubber parts.Upper shell 1 snaps together with lower shell body 2, forms air filter housing, and filter core 7 is housed in air filter housing.
Air filter suction tude 3 is connected on lower shell body 2, the suction port passing through for air filter suction tude 3 on lower shell body 2.Air filter air outlet 4 is arranged on upper shell 1, and for connecting air filter steam outlet pipe (not shown), the above is identical with traditional air filter assembly that is applicable to automobile, does not repeat them here.
Difference is: (1) air filter suction tude 3 extends in lower shell body 2, to change the divergence ratio that flows into air in air filter inner chamber, effectively reduce the noise of this position, the air inlet resistance that simultaneously makes to flow in air filter inner chamber is less, the smoothness of air-flow increases, and intake efficiency improves.
(2) one end of interpolation pipe 5 is unsettled over against the interpolation pipe 5 of air filter air outlet 4 in upper shell 1, to be provided with one, and the other end is connected on air filter air outlet 4.Interpolation pipe 5 is away from one end of air filter air outlet 4 with extension mouth, and the side by air filter inner chamber is expanding.This interpolation pipe guides airflow smooth from air filter inner chamber inflow engine suction tude by extension mouth, effectively prevents the generation of eddy current, and the improvement of the smooth-going and noise of air-flow is had to remarkable result.
Be preferably, the length that air filter suction tude 3 extends in lower shell body 2 is 1/3 of air filter lower shell body 2 width, the length of interpolation pipe 5 is 1/3 of upper and lower casing 1,2 height sums, further to improve the air inlet effect of air filter, the width of lower shell body 2 is D, and upper and lower casing 1,2 height sums are H.
Claims (2)
1. an air filter assembly that is applicable to automobile, comprise upper shell (1), lower shell body (2), air filter suction tude (3) and air filter air outlet (4), described air filter suction tude (3) is connected on lower shell body (2), air filter air outlet (4) is arranged on upper shell (1), it is characterized in that: described air filter suction tude (3) extends in lower shell body (2), in described upper shell (1), be provided with an interpolation pipe over against air filter air outlet (4) (5), described interpolation pipe (5) away from the one end of air filter air outlet (4) with extension mouth.
2. according to the air filter assembly that is applicable to automobile claimed in claim 1, it is characterized in that: the length that described air filter suction tude (3) extends in lower shell body (2) is 1/3 of air filter lower shell body (2) width, the length of described interpolation pipe (5) is 1/3 of upper and lower casing (1,2) height sum.
