Description
Technical field
The present invention relates to a kind of automobile air inlet system parts, particularly to a kind of air inflow structure of automobile air cleaner.
Background technology
Air filter of automobile is a pith of automobile air inlet system, air filter of automobile was mainly used in the impurity particle in air filtering, reduce the abrasion of the parts such as cylinder, piston and piston ring, the function play the service life extending electromotor, reducing engine charge noise.The air inlet component of air filter is typically located on the water tank upper beam after headlight for vehicles or above air-inlet grille, air filter in the market is to reduce the intake air temperature of air, increase the air inflow of fresh air, in the case of the design condition of automobile own allows, typically the air inlet component of air filter is arranged on the water tank upper beam above air-inlet grille, this air inlet component includes air inlet and escape pipe, and escape pipe is connected with air filter cavity by air entraining pipe.
Aforesaid way is used to arrange the air inlet component of air filter, due in air inlet component and be not intended for the component of draining, when rainy day or carwash, water droplet enters air inlet component easily by air-inlet grille thus flows in air filter, cause air filter intracavity hydrops, the service life of air filter inner filter core will be affected, time serious, even affect the performance of electromotor and the reliability of electromotor.
Summary of the invention
The technical problem to be solved is to provide a kind of air inflow structure of automobile air cleaner that can effectively discharge water droplet.
Technical scheme is as follows: a kind of air inflow structure of automobile air cleaner, including the air filter air inlet cavity of hollow structure, this air inlet cavity is provided with air inlet and escape pipe, and the extreme lower position in described inlet chamber body is provided with the water falling hole for draining.
Using technique scheme, the extreme lower position in inlet chamber body is provided with water falling hole, and when water droplet enters air inlet cavity, the hydrops in air filter air intake structure can effectively be discharged by water falling hole, prevents water droplet from entering in air filter cavity.
The top of described air inlet cavity is provided with convex closure.Convex closure is for efficiently separating the air-flow from air inlet entrance air inlet cavity and water and to design, when air-flow and water strike on convex closure simultaneously, air-flow can pass through convex closure racing, then flow in escape pipe, and water is due to effect of inertia, is kept off down by convex closure, can be along wall, flow into air inlet cavity k level, be then discharged by water falling hole, prevent water from flowing in air filter cavity.
The bottom surface of described air inlet cavity is provided with the cambered surface for water guide.Flowed in escape pipe by bottom surface for enabling water droplet to flow to horizontal lowest surfaces, in inlet chamber body, be provided with the cambered surface of guide functions.
Isolating water droplet for enabling whole air inflow structure of automobile air cleaner preferably to reach, prevent water droplet from entering the effect of air filter, as preferably, described air inlet is located at the position that air inlet cavity front is top, and escape pipe is located at air inlet chamber rear side.
The extreme lower position that position is air inlet cavity that the bottom surface of described air inlet cavity is connected with side, escape pipe place.
Described convex closure is located at the side near escape pipe.
Described water falling hole is circular or oval or rectangle or polygon.
The height of convex closure is at least 3mm, and the angle that this convex closure produces away from side and its place air inlet cavity plane of escape pipe is within 130 °.
The interface point of described air inlet cavity and escape pipe lower end is not less than 8mm to the difference in height of the extreme lower position in inlet chamber body.
For making air filter air intake structure attractive in appearance, easy for installation, both sides, described air inlet lower end are provided with journal stirrup, and pilot hole is offered in the center of this journal stirrup.
Beneficial effects of the present invention:
1, air filter spatial arrangement structure is not being changed, effective admission amount in air filter does not reduces, in the case of not affecting air filter air inlet moulding, by optimizing the shape of air inflow structure of automobile air cleaner, water falling hole can effectively discharge the water droplet flowing into air filter air intake structure.
2, air-flow and water can be separated by convex closure, and cambered surface plays the effect guiding current direction, and by water falling hole, water is finally discharged air filter air intake structure.
