The present invention mainly relates to an air filter for air purification used in a vehicle and the like, and in particular, to install a velvet layer that primarily filters the air flowing into the engine and a filter paper that filters the air inlet for a smooth output of the vehicle engine. And inserting an intermediate member to increase the adsorption area of impurities and inserting an elastic body between the intermediate members so that the intermediate member does not come into close contact with the high air pressure, thereby extending the life of the air filter. In addition to being able to reduce fuel consumption.

In general, the air filter installed in the air inlet of the carburetor mounted on the vehicle filters out foreign substances such as dust and sand contained in the air, and the filtered air is mixed with the fuel and supplied into the engine and burned together with the fuel. Such an air filter plays an important role in improving engine combustion efficiency and extending engine life by filtering foreign substances contained in air.

The conventional air filter as described above is largely divided into two, one of which is the air outlet is formed in the center of the cylindrical housing formed with an air inlet on one side, the sealing cap is formed on the upper opening and the inside of the housing has a corrugated shape It is a cylindrical air filter provided with filter paper, and the other one is a plate-shaped air filter having a structure in which a pleated filter paper is mounted inside a rectangular box-shaped casing with an upper opening.

However, since the conventional air filters are provided with only one filter paper made of a thick non-woven fabric, when used for a long time, foreign matter is adsorbed on the filter paper and the filter function is extremely degraded. By interfering with the normal amount of air flowing into the engine and the air resistance, there is a problem of increasing fuel consumption along with a decrease in engine power.

Meanwhile, many air cleaners have been proposed to solve the above problems. Application number 1985-169 published in the Republic of Korea Utility Model Publication "air cleaner regeneration method for air purification" relates to a regeneration method of attaching a thin cloth when removing the wheel attached to the air cleaner plate and attaching a new wheel. However, the air filter used in the air cleaner regeneration method for air purification is included in the air because the thin cloth is a simple cloth and does not have a structure in which a surface loop is cut pile and is woven into warp and weft yarns so that the gap is tight. It is not possible to effectively filter foreign substances, etc., and to increase the resistance of the air flowing into the engine, thereby reducing the amount of air inflow, thereby reducing the engine output and increasing fuel consumption.

In addition, Korean Utility Model Publication No. 1998-12293 "Air Purification Air Cleaner" is formed at regular intervals between the inner cylinder and the outer cylinder perforated with a circular vent hole from the inside of the lower flange, the fibrous By forming the filter in a sealed shape and inserting it between the inner and outer cylinders, only the fibrous filter can be replaced. Such an air cleaner has the advantage of replacing only the fibrous filter without discarding the air cleaner body, but the fibrous filter excludes the filter paper and has a simple fibrous structure in which the surface loop does not have a cut pile structure. Since only the primary filter composed of the filter is used, foreign matters contained in the air cannot be effectively removed, and there is a disadvantage of lowering the air intake amount.

Subsequently, Application No. 2002-66760 "Air Cleaner Structure" published in Korean Utility Model Publication discloses an auxiliary filter for protruding downwardly a predetermined length of coupling protrusions on both sides of the case, and filtering the foreign matter in the bottom of the case. It is coupled, but both ends of the sub-filter is fitted into the space between the case and the coupling protrusion to combine the sub-filter on the case bottom. Therefore, the structure of the air cleaner as described above has the advantage of extending the life of the filter member by using an auxiliary filter, but by using the main filter member and the auxiliary filter formed of a nonwoven fabric, the resistance of the air is increased due to the characteristics of the material to reduce the engine output There is a problem in that it generates and thus increases fuel consumption.

The present invention has been devised in view of the above points, the object of the present invention is to facilitate the smooth output of the engine by extending the life of the air filter by reducing the resistance of the air introduced while the various foreign substances contained in the air easily adsorbed It is to provide an air filter for air purification that can have an economic effect on consumers by increasing the replacement cycle.

A filter paper for collecting foreign substances in air; A velvet layer made of velvet having the same shape as that of the filter paper and laminated on the outer surface of the filter paper and having a cut pile portion whose surface is cut pile; And a connecting portion attaching the velvet layer to an outer surface of the filter paper.

An intermediate member in the form of a net is inserted between the filter paper and the velvet layer, and an elastic body is inserted to secure the space of the intermediate member, and the connection part is formed in a plurality of dots to secure a space between the filter paper and the velvet layer. Is done.

Hereinafter, an air filter for purifying air according to the present invention for achieving the above object will be described in more detail with reference to the accompanying drawings.

The velvet layer 20 is also called veludo or velvet as velvet or velour. The velvet is a base warp yarn 22 and a pile warp yarn 23 as warp yarns, and the base warp yarn 22 is a fabric showing a soft pile or loop on the fabric base. After weaving the weft warp yarn 22 and the pile warp yarn 23 alternately to make a file when weaving, the weft warp yarn 22 is cut to form a cut file. The cut pile portion 21 of the velvet layer 20 formed as described above effectively collects most of the coarse particles primarily in the foreign matter contained in the air passing through the air filter 1.

The velvet layer 20 is attached by a connecting portion 30 attached to the outer surface of the filter paper 10, the connecting portion 30 is predetermined on one surface of any one of the filter paper 10 or the velvet layer 20. It is made of a plurality of dots (dots) at intervals, but the connection portion 30 is preferably laminated and attached in a state in which the pleated form of the filter paper 10 and the velvet layer 20 is maintained by an adhesive or a sewing line.
