The present invention relates to a frame provided in an air cleaner filter that is installed in small and large vehicles, and filters foreign substances such as dust in the air sucked into the engine. In particular, the air can be disassembled and assembled to replace only the air filtration filter. It relates to a cleaner filter frame.

In general, the air cleaner filter used in various vehicles uses a dry filter composed of paper or a wet filter composed of a sponge according to a vehicle type, and the filter is mounted on a predetermined filter frame to remove air from the air introduced from the outside. Only the clean air is filtered and introduced into the carburettor to increase the combustion efficiency of the engine by smoothly burning the gas according to the mixture of the vaporized liquid fuel and the clean air.

Therefore, in order to prolong the life of the engine oil and to prevent the wear of the engine, it is necessary to replace the filter frequently. In this case, the filter and the frame are integrally combined and fixed so that the entire filter must be discarded and replaced with a new filter. As the frame is disposed of with the filter, there is a problem of environmental pollution due to the disposal of the damaged filter.

Then, the configuration of the conventional air cleaner filter will be briefly described with reference to FIGS. 1A and 1B.

1A and 1B are perspective views showing an embodiment of an air cleaner filter mounted on various vehicles according to the prior art, in which FIG. 1A shows an air cleaner filter for a small vehicle, and FIG. 1B shows an air cleaner filter for a large vehicle. In the figure, 31 is the upper filter frame, 32 is the lower filter frame, 31a, 32a is the upper and lower bent portion, 33 is the frame support, 34 is the filter, 35 is the rubber ring, respectively.

As shown in the figure, the air cleaner filter applied to a small vehicle is provided with a hollow upper and lower filter frames 31 and 32 formed of a metallic material on the upper and lower parts thereof, and the upper and lower filter frames 31 and 32 are both ends thereof. It is formed by bending the peripheral portion, the frame support 33 formed of a mesh to connect the upper and lower filter frames 31, 32 to the inside is welded and mounted.

The filter 34 formed of a predetermined paper or sponge is inserted into the upper and lower surfaces of the bent portions 31a and 32a of the upper and lower filter frames 31 and 32 so that only the clean air is used as the engine unit (not shown). It is filtered to inject. Herein, in order to prevent contaminants introduced into the contact gap between the upper and lower filter frames 31 and 32 and the filter 34, the adhesive roll such as glue 3 $ is attached to the upper and lower surfaces of the filter frames 31 and 32. Doing.

In addition, a predetermined size rubber ring (3%) is mounted on the upper and lower predetermined positions of the upper and lower filter frames 31 and 32 to contact the upper and lower filter frames 31 and 32 by air flowing from the inlet of the filter case. To prevent noise caused by friction with the lower end of the case and its lid.

As shown in FIG. 1b, the air cleaner filter used in the large vehicle is formed in a long cylindrical shape because the intake flow rate of the outside air is strong and a large amount of clean air must be introduced, and the upper and lower filter frames 31, 32) The frame support 33 formed of a mesh of metal is fixed to the inside and the outside, and a dry or wet filter is used therebetween.

In the conventional air cleaner filter configured as described above, since the frame support is fixed to the filter frame, the manufacturing work of inserting the filter into the bent portion and attaching the filter is very cumbersome, and the filter is contaminated because the upper and lower filters of the filter frame are bonded. There is an economically inefficient problem of exchanging both the filter and the frame in case of damage by the material, and there is a problem of environmental pollution due to the frame not consumed even when disposing of the damaged filter.

Therefore, the present invention has been made to solve the above-mentioned problems, by simplifying the disassembly and assembly of filter frames used in various vehicles with a simple configuration to improve the environmental pollution problem and manufacturing economics by replacing only the filter The purpose is to provide a cleaner filter frame.
