Description

The air-strainer that a kind of not sticking gray fibers in-depth filtration filter core constitutes

Technical field

The utility model relates to the combustion air cleaner field, specifically is the air-strainer that a kind of not sticking gray fibers in-depth filtration filter core constitutes.

Background technique

During internal combustion engine, if contain the wearing and tearing that impurity such as dust just will aggravate part in the suction air, so air filter for automobile must be housed, the major requirement of air-strainer be filtering efficiency height, flow resistance low, can the long period use and service free continuously.If the filter core of air-strainer is stopped up by dust, then internal-combustion engine sucks lack of air, and oil inflame is insufficient, can cause power output to descend, and tail gas pollution increases the weight of.

Existing air filter for automobile generally adopts the papery foldable filter element, wire netting supports, be characterized in belonging to surface layer and filter, it is little to filter hole, and filter core is stained with ash easily and is stopped up, inconvenience is cleaned, cause filtering effect to descend, the life-span reduces, and its related influence that brings is exactly to make oil inflame insufficient, engine output power descends, and tail gas pollution increases the weight of.

Existing air filter for automobile generally adopts metal shell, gets rusty easily, and weight is big, and manufacturing procedure is many, and homogeneity of product is poor.

Patent 01268409.0 discloses a kind of air filter for automobile core.By the involutory air-strainer core that fuses is separated, both can be respectively the filter screen of housing inner chamber and end thereof be cleaned dedusting.Compare with prior art, dismounting, cleaning, easy for installation, reusability is strong.

Patent 200520103606.4 discloses a kind of air filter for automobile that different size is taken over that connects, and it has a web, a filtering element (cartridge) and a loam cake at least; This lower cover is formed with an opening that runs through on it; This web is arranged at down on the cover gab, is formed with a perforate that runs through on the web and takes over for linking an external engine air admittance; This filtering element (cartridge) is arranged between lower cover and the lower cover; Perforate on the different webs can be different apertures, be arranged at down the web that covers by replacing, can make air-strainer have different perforate apertures, take in order to being linked to different engine air admittances, by this, air-strainer need not be offered different lower cover moulds, makes the cost of air-strainer to reduce.

Summary of the invention

The utility model purpose provides a kind of in-depth filtration air filtering core of not being stained with grey function, air-strainer of plastic monoblock structural member of having.

The technical solution of the utility model is for this reason, the air-strainer that a kind of not sticking gray fibers in-depth filtration filter core constitutes, comprise perforated cylinder, it is characterized in that: filter core adopts not sticking gray fibers in-depth filtration lamination coating, perforated cylinder in the filter core is provided with interface, one end of perforated cylinder seals, and an other end is provided with the interface of giving vent to anger; Be wound with at least one deck above the perforated cylinder and be not stained with grey filter material; Described filter core places a hat urceolus the inside, and the perforated cylinder of band interface is inserted in the intermediate hole of hat urceolus, and stretches out in urceolus, forms the interface of giving vent to anger; The closed end of perforated cylinder is concordant with the base of urceolus; Urceolus is buckled with enclosing cover on the base, and the enclosing cover the inside is provided with a plurality of pillars, and pillar is against on the closed end of perforated cylinder.

Improvement to such scheme is: the bound fraction of enclosing cover and urceolus is provided with connecting thread.

Improvement again to such scheme is: the perforated cylinder middle part is provided with a baffle ring.

Further improvement of these options is: the material of enclosing cover, urceolus, perforated cylinder is made with engineering plastics.

Beneficial effect:

The beneficial effects of the utility model are to have adopted not to be stained with gray fibers in-depth filtration filter core, are not afraid of and make moist, and are convenient to clean, and have reduced filter material plug-hole probability, have prolonged working life.Owing to adopted only three plastic monoblock structural members, not only designs simplification is installed and removed conveniently, weight saving, and, saved welding and paint operation, production technology is simplified, the manufacturing efficiency raising.

Compare with existing iron shell, the utility model adopts three plastic monoblock structural members, has made things convenient for and has taken cleaning apart, has alleviated product weight, the muscle change production technology, saved the paint operation.

Compare with existing individual layer filter material, the utility model is to adopt not to be stained with grey in-depth filtration filter core, has reduced the filter core obstruction, is convenient to clean.

Embodiment

The utility model such as Fig. 1, figure, 2 Fig. 3, Fig. 4, shown in Figure 5.

Fig. 1 is a kind of air-strainer that does not glue gray fibers deep layer air filtering core formation that designs according to the method described above, and it is by urceolus 1, and perforated cylinder 2 is not stained with grey filter material 3, and enclosing cover 4 is formed.

At least one deck is not stained with grey filter material 3 windings or is wound on the perforated cylinder 2, and an end of perforated cylinder 2 seals, and an other end prolongs the double interface of giving vent to anger of doing in back, and the design of perforated cylinder 2 middle parts has a baffle ring, is used to block filter material.

Urceolus 1 is a hat, and an end opens wide and design is useful on the internal thread that screws with enclosing cover 4, and design has the flange of being convenient to screw operation on this end excircle; An other end seals but the middle hole that equates with perforated cylinder 2 external diameters that has, and the non-closed end of perforated cylinder 2 inserts urceolus 1 and fits up to perforated cylinder edge, 2 middle part and urceolus 1 interior edge face, and extends out, and constitutes the interface of giving vent to anger.

Enclosing cover 4 small ends have intake interface, enclosing cover 4 big end designs are useful on the internal thread that screws with urceolus 1, the outer also design of big end has the flange of being convenient to screw operation, design is useful on the boss that props up perforated cylinder 2 in the big end, after enclosing cover 4 screws with urceolus 1, this boss has been pushed down the closed end of perforated cylinder 2, prevents that it is loosening.

Air has intake interface from enclosing cover 4 small ends and enters into the filter core outer space, enters perforated cylinder 2 backs after the filtration and directly comes out from the interface of giving vent to anger of perforated cylinder 2 one ends.

Be provided with seal ring between perforated cylinder 2 and the urceolus 1.
