Abstract

The utility model discloses a novel air filter comprising filter element materials repeatedly bent into a wave shape and a plastic frame, wherein a layer of metal filter screen is respectively arranged on the front side and the back side of the filter element materials; the filter screens and the filter element materials are cropped into the same volume and are simultaneously bent in wave shapes; the plastic frame covers the periphery of the wave-shaped filter element materials and the filter screens; and moreover, the peripheries of the filter element materials and the filter screens are fixedly into the plastic frame. The metal filter screens are stainless steel wire screens, and the filter element materials are PET filter sheet materials. Air passes through the novel air filter through the filter element materials in the wave structure, and the liquidity of adjacent sheet materials is smoother. The fixation of the stainless steel wires on the front side and the back side ensures that the air filter is not easy to deform, thereby reducing the filter effect. Moreover, the structure of the plastic frame is reasonable, thus the sealing performance is good. The utility model has the advantages of reasonable structure, convenient assembly and disassembly, good air filter effect, and the like.

Description

Novel air-strainer

Technical field

The utility model discloses a kind of novel air-strainer, belongs to air-strainer class manufacturing technology field, especially relates to filter cleaner accessory on the motor car engine.

Background technique

Air-strainer is in automotive engine air intake system, and it mainly acts on is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.The filtering material of present air filter generally is papery sheet material or non-weaving cloth, and as Fig. 1, filter comprises corrugated PET filter and is arranged at the frame that its same material is on every side made, both integrated designs.But the frame of existing filter is tabular being fixed between filter crest and the trough, the gap of facing crest mutually is provided with inhomogeneous, when passing through filter cleaner, air easily filter is produced distortion, thereby influenced airfiltering effect, the integral structure of existing filter has increased the cost and the difficulty of production in addition, and changes inconvenience.

The inventor is through studying for a long period of time and test of many times, and the air-strainer structure of creation one improvement is so just there is proposition of the present utility model.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, novel easily air-strainer of assembling and disassembling.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of novel air-strainer, comprise and be bent into corrugated filtration core and plastic frame repeatedly, wherein, the positive and negative that filters core respectively is provided with the layer of metal filter screen, filter screen cuts area with the filtration core and quite and simultaneously is bent into wavy, described plastic frame is coated on wavy filtration core and filter screen periphery, and filters the peripheral affixed of core and filter screen and go on the plastic frame.

Further, described metal filter screen is the stainless steel and iron silk screen, and this filter screen is close to the two sides of filtering core and is played the wavy of support filtration core.

Further, described filtration core is that PET filters sheet material, can promote its filtering effect by its material behavior.

Further, described filtration core and filter screen are bent into equally spaced wave structure repeatedly, and the distance of facing mutually between crest is 0.8-1.2cm.

Further, described plastic frame is beneficial to whole device and installs airtight along filtering the sealing draw-in groove that the core periphery is provided with annular.

When the filtration core of the utility model by wave structure passed through air, circulation was more unobstructed facing mutually between sheet material, and the Stainless Steel Wire of positive and negative is fixing, did not more make it yielding and reduced the effect of filtering.The setting rational in infrastructure of plastic frame makes its good seal performance in addition, and plastic materials is better than the frame sealability of PET lamination coating.

The utlity model has advantages such as the convenient and filtered air of rational in infrastructure, assembling and disassembling is effective.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: structure such as Fig. 2,3, shown in Figure 4, a kind of novel air-strainer comprises and is bent into corrugated filtration core 1 and plastic frame 2 repeatedly, wherein, the positive and negative that filters core 1 respectively is provided with layer of

metal filter screen

3 and 4, filter screen cuts area with filtration core 1 and quite and simultaneously is bent into wavy, described plastic frame 2 is coated on wavy filtration core and filter screen periphery, and filters the peripheral affixed of core and filter screen and go on the plastic frame.

Metal filter screen

3,4 is the stainless steel and iron silk screen, and this filter screen is close to the two sides of filtering core 1 and is played the wavy of support filtration core.

Filtering core 1 is that PET filters sheet material, can promote its filtering effect by its material behavior.

Filter core 1 and metal filter

screen filter screen

3,4 and be bent into equally spaced wave structure repeatedly, and the distance of facing mutually between crest is 0.8-1.2cm.

Plastic frame 2 is beneficial to whole device and installs airtight along filtering the sealing draw-in groove 20 that the core periphery is provided with annular.

The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
