Description

Air purifier filter media for automobiles {The filter of air purifier for a vehicle}

The present invention relates to an air purifier filter material for automobiles, and more particularly, is mounted in an air cleaner to filter the dust of air flowing into the engine from the intake system of the vehicle, and then supply the filtered clean air to the engine for the life of the engine. By replacing only the air filter of the automotive air cleaner filter medium used to extend the filter, it is possible to reduce the amount of waste while protecting the environment while reducing the cost of replacing the entire air cleaner filter medium including the air filter. The present invention relates to an air purifier filter medium for automobiles that can reduce waste of resources.

Generally, the air purifier filter material for automobiles removes foreign substances including dust in the air sucked by the engine and removes intake noise generated in the intake pipe. As dust accumulates on the air filter, air intake is not smooth and dust in the air cannot be effectively filtered out, which causes the life of the engine to be shortened.

Therefore, when the air purifier filter medium is used for a long time, the output of the engine is reduced, so the air purifier filter medium should be replaced at an appropriate time to extend the life of the engine and to properly display the engine output.

However, the air purifier filter medium, which is closely related to the performance of the engine of the automobile as described above, is rarely manufactured to replace only the air filter that filters dust, so in order to replace the air purifier filter medium, the air filter and the air purifier Since the whole filter medium has to be replaced, there is a problem of excessive replacement cost, waste of resources, and excessive generation of waste.

In order to solve the above problems, an air purifier filter medium configured to replace only an air filter is known in Korean Laid-Open Utility Model Publication No. 1998-061332 (1999, 11,05). Briefly described as follows.

As shown in the drawing, a conventional air purifier filter medium is integrally coupled with a lower cap 13 having an outlet (not shown) formed at a lower portion of a cage 10 having a plurality of through holes 11 formed around its perimeter. The upper portion of the cage 10 is integrally coupled to the panel 14 protruding the coupling bolt 14a in the central portion.

In addition, an air filter 16 to filter dust is enclosed in the front circumference of the cage 10, and an upper cap having a coupling hole 15 through which the coupling bolt 14a penetrates to the upper portion of the panel 14. 12 is placed, the upper portion of the upper cap 12 is made to be coupled to the washer 17 and the coupling nut 18 is coupled to the coupling bolt 14a.

The conventional air purifier filter medium configured as described above is configured to be separated from the cage 10 by the coupling cap 14a, the coupling nut 18, and the washer 17 to form an air filter 16. In order to replace), after removing the coupling nut 18, washer 17 and the upper cap 12 from the coupling bolt 14a, only the air filter 16 in the cage 10, the air cleaner Since it is not necessary to replace the entire filter medium, it is possible to solve the problems such as cost reduction, waste of resources and excessive generation of waste due to the replacement of the air purifier filter medium.

However, in the conventional air purifier filter medium configured to replace only the air filter 16 as described above, the separate panel 14 is installed in the cage 10 in order to install the coupling bolt 14a on the upper portion of the cage 10.

There was a hassle such as combining the panel 14 which does not work to the upper part of the cage 10.

When the upper cap 12 is coupled to the coupling bolt 14a having a small diameter, the coupling force between the upper cap 12 and the coupling bolt 14a is relatively small, so that the upper cap 12 may be cage 10 even in a small impact. There is a problem that the air containing dust or foreign matter is introduced into the engine through the gap between the upper cap 12 and the cage 10 is separated from the upper portion of the), in order to install the air purifier filter material inside the air cleaner The volume of the air purifier filter medium must be made as small as the height of the coupling bolt 14a protruding from the panel 14, thereby reducing the amount of air sent to the engine.

In order to solve the conventional problems as described above, the present invention is simple to configure the air cleaner filter material that can replace the air filter, so that anyone can easily replace the air filter, the gap formed between the dust and foreign matter between the cap and the cage In order to prevent the inflow into the engine through the air in advance, while the air filter can be reduced in volume to reduce the transportation cost to the technical problem.

To this end, the present invention, the upper and lower caps are formed in the upper and lower portions of the inner cage formed in the periphery of the opening, the outlet cap is formed on one side or both sides, the air filter is surrounded around the inner cage, the air filter In the periphery of the through-hole is formed so as to surround the outer cage, the inner cage forms a cylinder with a radial mountain and floor to form an inner tightening step so as to protrude outward on the upper and lower ends of the cylinder, the inner The outer wall of the cage is formed of a radial mountain and a floor formed in the inner cage and surrounded by an air filter having one end in the longitudinal direction, and the outer cage surrounding the air filter is a radial mountain and a floor formed in the inner cage. To form a cylinder so that the cylinder can be opened in both sides, one side is coupled by a hinge and the other side is caught with the clip Lee and each installed to be coupled to each other, the upper and lower cylinders of the outer cage is characterized in that formed by forming an outer tightening step projecting inward to face the inner tightening step.
