Abstract

The utility model relates to an air filter core used for automobile engines, and is composed of an upper support body and a lower support body which are provided with an air inlet middle hole and are connected together. The utility model is characterized in that a plurality of convex inclined deflector plates are uniformly arranged on the lower surface of the air inlet middle hole of the lower support body; a winding concave groove is arranged at the outer side of the air inlet middle hole; filtering oil is filled in the concave groove; a winding penetrating groove is arranged at the outer side of the air inlet middle hole of the upper support body; a winding steel-wire filter screen is arranged in the penetrating groove; and a diversion device is arranged between the outer side walls of the concave groove and the penetrating groove. The utility model has the advantages of good dust filtering effect, long service life, cleanness, and being particularly suitable for use of engineering vehicles in the bad environment of large wind sand.

Description

The air-strainer core

Technical field:

The utility model belongs to a kind of parts of motor car engine with air-strainer, is specifically related to a kind of air-strainer core.

Background technique:

The filtering effect of air filter for automobile, crux depends on the air-strainer core, the air-strainer core of present domestic use, the one, the papery dry type is to be connected and composed through pressing folded filter paper by multilayer, and its shortcoming is that filter element easily stops up, can not clean and reuse, and the life-span is short; The 2nd, oil bath type is to make air-flow flow through filter oil meter face at turning point, and dust particle is adhered to because of inertia gets rid of to liquid level, in strainer filtering entered motor, its shortcoming was that filtering machine oil is easily dirty again, and the mesh of filter screen is big, filter the weak effect of dirt, influence the working life of air-strainer.This filter cleaner of two types all can not satisfy the filtering needs of heavy goods vehicles and engineering truck, therefore partly automobile production producer is linked together use with dry type, two filter cleaners of oil bath type with pipeline, improve the filtering effect, its shortcoming is to take up room greatly, waste material cost height, during installation fee, the part vehicle can't adopt because of the space is limited.

Summary of the invention:

The purpose of this utility model provides that a kind of filter dirt is effective, and the life-span is long, is particluarly suitable for the air-strainer core that the engineering truck under the rugged environment such as dust storm is big uses.

The technical solution of the utility model is: a kind of air-strainer core, form by upper and lower two supports that are provided with the air inlet mesopore and link together, it is characterized in that, on the air inlet mesopore downside surface of lower support, be laid with the oblique guide plate of downward convex, the outside is provided with a volume groove, and filtering machine oil is housed in the groove; In being provided with the saturating groove of a saturating groove of volume, the air inlet mesopore outside of upper support body is provided with the coiling Steel net; Between groove and saturating groove outer side wall, be provided with flow guide device.

Wherein, described flow guide device is made up of the oblique guide plate that is laid with on the stake body.

Described flow guide device is made up of the oblique guide plate of outside convex that is laid with on the saturating groove outer side wall.

Described flow guide device is made up of the oblique guide plate of inwardly protruding shape that is laid with on the groove outer side wall.

Described coiling Steel net is to be installed in the groove by the establishment stainless (steel) wire on it.

The utility model adopts said structure, and during work, ambient air oblique guide plate on lower support produces spiral air flow, under effect of inertia, dust granules bigger in the air is thrown away, and excretes, and plays the effect of coarse filtration; Through flow guide device, form strong spiral air flow, drive filtering machine oil and in groove, flow, increased the adsorptive power of filtering machine oil to dust, enter in the motor by steam outlet pipe through further filtration of coiling Steel net again, play the fine filtering effect.Therefore it is effective to have filter dirt, and the life-span is long, and is clean, is particluarly suitable for the obvious advantage that the engineering truck under the rugged environment such as dust storm is big uses.
