Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model relates to a high-efficient type automobile engine air filter core embodiment of admitting air's schematic diagram, fig. 2 is the utility model relates to a cross-sectional view of safety core embodiment in high-efficient type automobile engine air filter core, as shown in the figure, a high-efficient type automobile engine air filter core of admitting air, including from inside to outside safety core 1, essence filter core 2 and the primary filter mantle 3 that sets gradually, the air is inside from primary filter mantle 3, essence filter core 2, safety core 1 gets into, realizes the effective filtration of air.

The primary filter cover 3 filters dust with the granularity larger than 75 mu m, the primary filter cover is made of modified polypropylene materials and is woven into an ultrafine filter screen, the appearance of the primary filter cover is matched with that of the fine filter core, and therefore the primary filter cover can play a role in primary filtration and also has the effect of preventing sand from being accumulated on the surface.

The fine filter element 2 filters dust with the granularity larger than 10 mu m, the fine filter element is made of terylene spunbonded hot-rolled non-woven fabric, and the fine filter cloth (with the folding depth of 18mm, the folding number of 80 and the height of 192mm) is wound into a frustum shape, so that the sufficient air input is ensured, and the sand accumulation is avoided.

The outer surface of the fine filter element 2 is of a frustum structure, so that the area of the filter element is obviously increased, and the filtering effect is improved. The inner side of the fine filter element 2 is provided with a frustum-shaped first supporting framework 4, the first supporting framework 4 is a latticed metal framework, and the first supporting framework 4 is used for supporting the fine filter element.

The safety core 1 comprises a filtering layer and an anti-corrosion supporting net, wherein the filtering layer is arranged and folded, the anti-corrosion supporting net is arranged on the inner side and the outer side of the filtering layer, the filtering layer is used for filtering air, and the supporting net has a supporting function when achieving a filtering effect. The safety core 1 filters dust with the granularity larger than 30 mu m, the filter layer is made of glass fiber paper filter material, and the anti-corrosion support net enhances the bearing strength of the filter layer. And when the filter layer is damaged, the support net still temporarily protects the engine from sand and dust, and the state ensures the endurance mileage of 50-100km for adsorbing ultrafine dust. The inner side of the safety core 1 is provided with a frustum-shaped second supporting framework 5, and the second supporting framework 5 is a latticed metal frame and provides support for the safety core.

The utility model discloses a filter core, first support framework 4 is the frustum type with second support framework 5, guarantees its bearing strength. Meanwhile, the frustum structure on the outer surface of the fine filter element 2 obviously improves the filtering effect. After the safety element 1, the fine filter element 2 and the primary filter cover 3 are assembled from inside to outside, the two ends of the whole filter element are connected with a fixed support on a vehicle body through an air inlet joint, and stable fixation is realized.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the present invention, and these modifications should also be construed as the protection scope of the present invention.
