Abstract

The utility model relates to an air filter element and belongs to the technical field of air purification of automobile engine. The air filtering device comprises an upper end cover, a lower end cover, and an inner net and filter paper which are positioned between the upper and the lower end covers. The upper end cover is made of soft polyurethane material; the lower end cover is formed in such a manner that a galvanized iron cover is externally cast with polyurethane PU; and the upper and the lower end covers, the inner net and the filter paper are integrally formed. Since the utility model adopts the integrated structure made of rubber and iron materials, not only can air leakage of the traditional air filter element and easy falling of parts be solved, but also the filter element is strengthened; the air filtering device can facilitate bolt fastening during assembly, and can ensure that air is better filtered through specified filter material, thereby achieving better filter effect and prolonging the service life of an engine and an internal combustion engine.

Description

Air filtering core

Technical field

The utility model relates to a kind of air filter, belongs to automobile engine air purifying process field.

Background technology

At present, the air filtering core that generally uses on automobile engine mainly is with filter core illustrated in figures 1 and 2.The upper and lower end cap of filter core shown in Figure 1 is zinc-plated iron covering, its poor sealing, and poor impact resistance is difficult for long-distance transport, and comes off easily.Filter core shown in Figure 2 up and down end cap is polyurethane (PU) material and makes, and its sealing is good, but fastness is relatively poor, and bolt is fastening when being not suitable for assembling.Therefore be necessary it is further improved.

Novel content

The purpose of this utility model is to have deficiency in view of above-mentioned prior art, and the air filtering core that provides a kind of automobile engine to use.Air filtering core provided by the utility model has not only solved gas leakage of conventional air filter core and the caducous phenomenon of part, and bolt fastening when having reinforced filter core and being fit to assembling, thereby and can better make air reach better filter effect in the filter material filtration of appointment, guaranteed the operate as normal of air filter.

The purpose of this utility model realizes by following technical proposals, and air filtering core provided by the utility model constitutes by upper end cover, bottom end cover and at Intranet and the filter paper between the end cap up and down.This upper end cover is made by the softer polyurethane material of material, and this bottom end cover is made up of the outer cast polyurethane PU lid of zinc-plated iron covering, and described upper and lower end cap and Intranet and filter paper are one-body molded.The utility model has adopted the incorporate structure of glue iron, not only solved the phenomenon of the difficult long-distance transport of conventional air filter core, and reinforced filter core, bolt is fastening when being fit to assembling, improved the quality of product, make the effective filtration area of filter paper obtain maximization, the service life of having improved engine and internal combustion engine.

Air filtering core provided by the utility model is not only shock-resistant, and has thoroughly solved gas leakage and the caducous phenomenon of part, has guaranteed the filter effect that air filtering core is good.

Characteristics of the present utility model are that bottom end cover adopts the incorporate structure of glue iron, have not only reinforced filter core, and bolt fastening when being fit to assembling.Solved the deficiency that the conventional air filter core exists.

The designed air filtering core of the utility model is mainly used in the various air filters that automobile engine or plant equipment are used.

Below just relevant technology contents of the present utility model and detailed description, existing conjunction with figs. and given embodiment describe as follows.

Description of drawings

Fig. 1 is a kind of schematic diagram of air filtering core of prior art;

Fig. 2 is the schematic diagram of the air filtering core of another kind of prior art;

Fig. 3 is the front view of the designed air filtering core of the utility model.

The specific embodiment

Please referring to Fig. 3, air filtering core provided by the utility model constitutes by upper end cover 11, bottom end cover 14 and at Intranet 12 and the filter paper 13 between the end cap up and down.This upper end cover 11 is made by the softer polyurethane material of material, and this bottom end cover 14 is made up of zinc-plated iron covering 15 outer cast polyurethane PU lids 16, and described upper end cover 11, bottom end cover 14 and Intranet 12 and filter paper 13 are one-body molded.

Air filtering core shown in Figure 3, its bottom end cover 14 is made up of zinc-plated iron covering 15 outer cast polyurethane PU lids 16, not only good airproof performance, shock-resistant, suitable long-distance transport, and reinforced filter core, solved the deficiency that the conventional air filter core exists.

There is a circular hole at the center of its described zinc-plated iron covering 14, fixing filter core when being used to assemble.It is more firm when assembling.

According to above-mentioned structure, the more existing air filtering core of this air filtering core has more practicality.

Yet above-mentioned explanation only is embodiment of the present utility model, and is non-for limiting embodiment of the present utility model; All personages who is familiar with this skill, it complies with feature category of the present utility model, and other equivalence of having done changes or modifies, and as size, material selection or change of shape etc., all should be encompassed in the utility model institute claim.

Claims

1. air filtering core, it is characterized in that it constitutes by upper end cover, bottom end cover and at Intranet and the filter paper between the end cap up and down, this upper end cover is made by the softer polyurethane material of material, this bottom end cover is made up of the outer cast polyurethane PU lid of zinc-plated iron covering, and described upper and lower end cap and Intranet and filter paper are one-body molded.

2. air filtering core according to claim 1 is characterized in that described bottom end cover has adopted the incorporate structure of glue iron.
