The upper plane filter paper on the upper layer of the corrugated filter paper and the lower plane filter paper attached to the lower layer of the corrugated filter paper. There is an external sealant between the outer end of the corrugated filter paper and the lower plane filter paper, and the inner end of the corrugated filter paper and the upper plane filter paper. With inner sealant. The utility model has a reasonable structural design, not only small in size, but also increases the filter area of the filter paper, increases the dust holding capacity, thus achieves better filtering effect, prolongs the service life of the air filter, and is conducive to popularization and use.

Description

new air filter

technical field

The utility model relates to an air filter, in particular to a novel air filter.

Background technique

Currently, an air filter is a device used to remove particulate impurities in the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. However, the traditional air filter is not only bulky, but also the filter paper has a small filtering area and a small dust holding capacity, resulting in unsatisfactory filtering effect and short service life.

Utility model content

The utility model aims to solve the above-mentioned problems in the prior art, and provides a new type of air filter, which not only reduces the volume, but also increases the filtering area of the filter paper and has a large dust holding capacity.

The technical solution adopted by the utility model to solve its technical problems: this new type of air filter includes a filter core, the filter core is spirally wound by filter paper to form a columnar structure, the outer end side of the filter core is fixed with an end cover, and the filter paper Including the corrugated filter paper in the middle layer, the upper plane filter paper attached to the upper layer of the corrugated filter paper and the lower plane filter paper attached to the lower layer of the corrugated filter paper, and an outer sealant is provided between the outer end of the corrugated filter paper and the lower plane filter paper, An inner sealant is provided between the inner end of the corrugated filter paper and the upper plane filter paper. The filter element is spirally wound by filter paper to form a cylindrical structure, which can reduce the volume of the air filter while fully filtering the air.

In order to further improve, the outer end surface of the filter element protrudes outside the end cover.

The beneficial effects of the utility model are: the utility model has a reasonable structural design, not only is small in size, but also increases the filtering area of the filter paper and the dust holding capacity, thereby achieving a better filtering effect and prolonging the service life of the air filter , which is conducive to popularization and use.

detailed description

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

Referring to the accompanying drawings: this new type of air filter in this embodiment includes a filter element 1, the filter element 1 is spirally wound by a filter paper 2 to form a cylindrical structure, and an end cover 3 is fixed on the outer side of the filter element 1. The filter paper 2 includes the corrugated filter paper 4 of the middle layer, the upper plane filter paper 5 attached to the upper layer of the corrugated filter paper 4 and the lower plane filter paper 6 attached to the lower layer of the corrugated filter paper 4, the outer end of the corrugated filter paper 4 and the lower plane filter paper An outer sealant 7 is provided between 6, and an inner sealant 8 is provided between the inner end of the corrugated filter paper 4 and the upper plane filter paper 5. The outer end surface of the filter element 1 protrudes outside the end cover 3 . The filter element 1 is spirally wound by the filter paper 2 to form a cylindrical structure, which can reduce the volume of the air filter while fully filtering the air.

As shown in Figure 5, the air enters the air filter, because an inner sealant 8 is provided between the inner end of the corrugated filter paper 4 and the upper plane filter paper 5, and an inner sealant 8 is provided between the outer end of the corrugated filter paper 4 and the lower plane filter paper 6. With the outer sealant 7, the air can only enter through the corrugated filter paper 4 in the direction shown by the arrow in the figure, so as to achieve sufficient filtration.

The length of the corrugated filter paper 4 is the dust-holding depth, which can fully contain impurities, has a large dust-holding capacity, and has a longer service life.

Although the present invention has been illustrated and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims.
