CN205064136U - Novel air cleaner filter element group stay knot constructs - Google Patents

Abstract

The utility model discloses a novel air cleaner filter element group stay knot constructs, present air cleaner filter core has two kinds of structures, firstly goes up the whole metal iron cover that use of lower extreme, and sealing material is the end cap seal circle under that bonds, go up the whole PU that use of lower cover to glue the pouring for one kind, sealing material directly is the PU castable. PU air cleaner and metal iron cover air cleaner be characteristics separately: PU air cleaner takes shape for PU glues the injecting glue, and the speed of production is fast, does not need the sticking the sealing circle, and is with low costs, is the air cleaner development trend, and sealed main to lean on the filter assembly to compress tightly air filter sealed, and metal iron cover air cleaner and the sealed lock nut press the sealing that use of assembly are sealed effectual, but consume more metal resource, and be with high costs. The utility model discloses combining two kinds of air cleaner structures, taking shape the sealed end of air cleaner with the PU injecting glue, sealed effect is guaranteed promptly to metal iron cover structure for the tail end, reduces the metal again and consumes, practices thrift the cost, durable.

Description

A kind of Novel filter element of air filter composite structure

Technical field

The utility model belongs to technical field of automobile parts, particularly relates to a kind of Novel filter element of air filter composite structure.

Background technique

Air filter for automobile is arranged in engine aspirating system, and its Main Function is filtered air, and the impurity such as blocks dust enter motor, affects the burning of motor internal-combustion engine, so air-strainer sealing quality, directly affects service life of aeroengine.Original automobile PU air-strainer sealing, the wiper seal of main dependence air cleaner assy enclosing cover, and assembly material is PP moulding, although it can ensure the gas permeability of filtering material, but in use easily there is damaged and deformation, to the normal sealing of air-strainer be affected, thus motor will be worked the mischief.The air-strainer sealing of metal end is locked by feed screw nut, good sealing effect, but air filtering core metallic material consumption is many, and manufacturing efficiency is low.

Model utility content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, a kind of Novel filter element of air filter composite structure is provided, in use easily there is normal sealing that is damaged and deformation effect air-strainer with the filter core assembly solving existing air-strainer, thus motor is worked the mischief problem.

For achieving the above object, the utility model solves the technological scheme that its technical problem adopts: a kind of Novel filter element of air filter composite structure, comprise filter core 1, filter core 1 is installed in assembly shell 2 by locking nut 3, assembly shell 2 has extraneous suction port 5 and the motivation mouth of pipe 6 of setting out, filter core 1 upper end is PU seal ring 4, and tail end is metal iron covering.Namely the utility model ensures sealing effect, reduces again metallic material and consumes, saved client cost.

Existing air cleaner cartridge has two kinds of structures, and one is that upper and lower end all uses metal iron covering, and sealing material is for being bonded in front cover seal ring; Another kind is that upper and lower covers all uses PU glue, and sealing material is directly for PU injecting glue is shaped.

Described PU type air-strainer and metal iron covering air-strainer features: PU type air-strainer is that PU glue injecting glue is shaped, speed of production is fast, do not need adhering and sealing circle, cost of production is low, be air filter for automobile development trend, the main filter assembly that relies on of its sealing compresses air filtering core sealing, if filter housing distortion may cause air filtering core poorly sealed, air then directly enters motor without filtration, causes engine damage; Metal iron covering air-strainer and assembly seal uses locking nut press seal, good sealing effect, but consumes more metals resources, and cost is higher.

The present invention is in conjunction with two kinds of air filtering device structures, existing air-strainer sealed end PU injecting glue is shaped, tail end metal iron covering structure, namely sealing effect is ensured, reduce again metallic material to consume, directly can carry out with existing product the renewal that substitutes, for existing filter cleaner product finds total solution, make the updating and upgrading of a product have the guarantee of the new source of goods.The cost that the renewal of greatly having saved client uses.

Embodiment

Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.

Referring to drawings and Examples, the utility model is described in further detail:

From accompanying drawing 1 ~ 3, existing crown cap structural gap filter element structure of filter schematic diagram, as shown in Figure 1, described metal end air cleaner cartridge structure, formed primarily of filter core 1, assembly shell 2, locking nut 3, bonding seal ring 4, extraneous suction port 5, motivation of the setting out mouth of pipe 6.

Existing PU structural gap filter element structure of filter schematic diagram, as shown in Figure 2, described PU structural gap filter element structure of filter, formed primarily of filter core 1, assembly shell 2, PU seal ring 3, PU stuffing box gland 4, extraneous suction port 5, motivation of the setting out mouth of pipe 6.

The alternative combinations of two kinds of described existing products, as shown in Figure 3, described novel combining structure air cleaner cartridge structural representation, primarily of filter core 1, assembly shell 2, locking nut 3, PU seal ring 4, extraneous suction port 5, enters motor port 6 and formed.In fact upgrading to change only needs to open assembly shell, the new filter core of PU type of corresponding model is directly changed, still buckles metal end and be tightened by bolts.Sealing configuration pattern, than original product better effects if, is worth being promoted in automobile industry.

The above, be only the utility model embodiment, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the restriction of the utility model claim and description and claims with modify, all should still belong in scope that the utility model patent contains.
