Abstract

The utility model provides an optimize empty filter core of engine of rolling over shape design, includes casing and filter paper, filter paper encircles on the surface of casing, the first book of the folding formation interval arrangement of filter paper is high with the second book. Having increased the broken number of filter media in the same filter core size, having improved filter area, the surface current that has reduced the pollutant is fast, can also effectively prevent that adjacent straining from rolling over the coalescence that sinks simultaneously, guarantees that flow path is unblocked, improves the actual life of filter core.

Description

A kind of motor air filter filter core optimizing the design of folding shape

Technical field

The utility model relates to engine charge and filters or industrial dedusting filtration art, is specifically related to a kind of motor air filter filter core optimizing the design of folding shape.

Background technique

Air-strainer is as a kind of purification plant in motor car engine, it is made up of housing and filter core, and filter core is arranged in housing, for intercepting the various foreign matters (dust, the grains of sand etc.) in air, reduce its wearing and tearing to motor, thus extend the working life of motor.

At present, air filtering core filter cleaner mainly papery dry-type air cleaner conventional in motor car engine, the filter core of papery dry-type air cleaner adopts to be made through the micropore filter paper of RESIN FINISH, filter paper porous, loose, folding, there are certain mechanical strength and water resistance, having the advantages such as filtering efficiency is high, structure is simple, lightweight, cost is low, easy maintenance, is current most widely used automobile air cleaner.

The core component that filter paper filters as whole papery dry-type air cleaner, the quality of its quality directly affects the using effect of papery dry-type air cleaner.As shown in Figure 1: conventional filter paper often adopts homogeneous folding shape, roll over high larger time easily occur and roll over and fully effectively can not utilize the surface area of filtering material, thus air-filtering cannot be carried out fully, decrease the actual life of filter core.

Model utility content

For there being the defect of technology on overcoming, the utility model is called on and is being made full use of the filter area of filter material, effectively prevents filter core in using process and rolls over, promoting its working life.

For achieving the above object, the utility model adopts following technological scheme:

Optimize a motor air filter filter core for folding shape design, comprise housing and filter paper, described filter paper is looped around on the outer surface of housing, and described folded filter paper forms that spaced first folding is high and the second folding is high.

Further: the height that the second folding is high is the half of the height that the first folding is high.

Because technique scheme is used, the utility model has following advantages:

The utility model adopts the folding shape design optimized, the high interval of height two kinds folding is applied to in a filter core, make spaced arrangement, and height two kinds folding shape is homogeneous separately, makes it add the broken number of filter material in identical filter core size, improves filter area, reduce the surface current speed of pollutant, effectively can also prevent adjacent filter folding to subside coalescence simultaneously, ensure that flow channel is unimpeded, improve the actual life of filter core.

Accompanying drawing explanation

Fig. 1 is the structural representation of conventional filter paper folding shape design;

Fig. 2 is the folding shape project organization schematic diagram of the technical program;

Fig. 3 is for producing the roller structure schematic diagram that shown in Fig. 2, filter paper is used.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described:

Embodiment: shown in Fig. 1, Fig. 2, Fig. 3:

As shown in Figure 1, the bending structure of conventional filter paper is similar to sine wave, a high continuous arrangement distribution of folding.Roll over high larger time easily occur and roll over and fully effectively can not utilize the surface area of filtering material, air-filtering cannot be carried out fully.

A kind of filter paper folding shape design that Fig. 2 provides for the technical program, employing dual waves is spaced, wherein high crest is that the first folding is high by 1, low crest is that the second folding is high by 2, be spaced between first folding high 1 and the second folding height, and height two kinds folding shape is homogeneous separately, the crest height of the first folding high 1 is one times of the crest height of the second folding high 2.Adopt the filter paper of this kind of design around being arranged on housing, identical filter core size adds the broken number of filter material, improve filter area, reduce the surface current speed of pollutant, can also effectively prevent adjacent filter folding to subside coalescence simultaneously, guarantee flow channel is unimpeded, improves the actual life of filter core.

Fig. 3 is for for designing the pressure roller that the technical program filter paper adopts, and comprise pressure roller 3 and lower compression roller 4, described upper pressure roller 3 is evenly equipped with projection 5, and the described shape of projection 5 designs consistent with the folding shape of the filter paper of the technical program; Described lower compression roller 4 is evenly equipped with groove 6, and described groove 6 matches with projection 5.

Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.

Claims (2)

1. optimize a motor air filter filter core for folding shape design, comprise housing and filter paper, described filter paper is looped around on the outer surface of housing, it is characterized in that: described folded filter paper forms that spaced first folding is high and the second folding is high.

2. a kind of motor air filter filter core optimizing the design of folding shape according to claim 1, is characterized in that: the height that the second folding is high is the half of the height that the first folding is high.
