Abstract

The utility model relates to a filter element of an engine oil filter. The filter element comprises a hollow cylindrical body, wherein the hollow cylindrical body is formed by longitudinally folding filter paper; two axial ends of the body are respectively provided with two ring-shaped end surfaces; and the body is provided with two end covers covering the ring-shaped end surfaces respectively. The filter element is characterized in that the end covers are PU (Poly Urethane) end covers which are formed by PU injection molding on the ring-shaped end surfaces and are integrally combined with the filter paper. The end covers and the filter paper are integrally arranged by injection molding, so that the filter element has the advantages of saving the material cost, being conveniently processed, and enabling the filter paper to be difficult to close together so that the filter area is enlarged and the filter effect is improved.

Description

Element of oil filter

[technical field]

The utility model relates to the automobile filter apparatus field, is specifically related to a kind of element of oil filter.

[background technique]

In the motor car engine operation process, need combustion air, and contain sand usually in the air, foreign matters such as dust and steam, cause great number of issues therefrom: 1, after foreign matter gets into the cylinder body of motor, cause the wearing and tearing of cylinder body easily; If the volume of 2 foreign matters is bigger, then possibly stop up the engine air throttle valve body, cause valve body work to have some setbacks; 3, in foreign matter entering engine motor oil, then possibly bring the heavy wear between the whole friction pair of motor.Therefore, dispose filter cleaner before the motor car engine usually, and filter core is the critical piece of filter cleaner; Traditional element of oil filter generally includes by the longitudinal folding hollow cylindrical body that constitutes of filter paper material, and body shaft is respectively arranged with two annular end face to two ends; Yet body is to constitute by filter paper material is longitudinal folding; There is certain defective in its resistance to deformation intensity, therefore, existing technology be exactly with body-fixed on columnar iron frame; And coat the irony end cap two annular end face, iron frame and irony end cap are fixedly connected.This technological scheme has following defective: 1, the cost of material of iron frame and irony end cap is higher; 2, body and iron frame, irony end cap need hand assembled, first processed complex, and it two is societies now in the continuous promotion of human cost, has increased the cost of production of enterprise; 3, iron frame and irony end cap poor corrosion resistance.

[summary of the invention]

To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of with low cost, easy to process, better element of oil filter of rotproofness.

For realizing above-mentioned purpose; The utility model provides following technological scheme: comprise by the longitudinal folding hollow cylindrical body that constitutes of filter paper; Body shaft is respectively arranged with two annular end face to two ends; Body is provided with two end caps that cover annular end face respectively, it is characterized in that: the PU end cap with filter paper integrated combination of said end cap on annular end face, forming through the PU injection moulding.

Through adopting technique scheme; End cap and the injection moulding of filter paper one; Process conveniently, practiced thrift cost of material simultaneously, and filter paper is effectively separated in this structure; Thereby increased filter area, improved filtering effect, the common relatively end cap of end cap of PU material has better decay resistance simultaneously.

The utility model further is set to: said end cover surface is compounded with the nonwovens that layer of surface is provided with concave point.

Through adopting technique scheme, make end cover surface follow the adhesive strength of filter box better.

Below in conjunction with accompanying drawing the utility model is further described:

[description of drawings]

Fig. 1 is the sectional drawing of the utility model;

Fig. 2 is the plan view of the utility model;

Fig. 3 is the I portion enlarged view of the utility model.

[embodiment]

Referring to Fig. 1 to Fig. 3; The disclosed element of oil filter of the utility model; Comprise that by the filter paper 11 longitudinal folding hollow cylindrical bodies 1 that constitute, body 1 axial two ends are respectively arranged with two annular end face 2, body 1 is provided with two end caps 3 that cover annular end face 2 respectively; End cap 3 is on annular end face 2, to form through the PU injection moulding, and the extending end of the end cap 3 that said injection moulding forms is separated with the fold section of filter paper 11.

End cap 3 and filter paper 11 one injection mouldings processs conveniently, practiced thrift cost of material, and filter paper 11 are separated effectively in this structure, thereby have increased filter area, improved filtering effect, and the while end cap 3 of PU material has better decay resistance.

In the present embodiment, end cap 3 surface recombination have layer of surface to be provided with the nonwovens 4 of concave point, make end cap 3 surfaces better with the adhesive strength of filter box.
