Description

[0001] AUTOMOTIVE AIR CLEANER [0002]

The present invention relates to an air cleaner for a vehicle, and more particularly, it relates to an air cleaner for a vehicle, in which replacement (insertion and removal) of a filter element is extremely simplified by applying a structure for replacing a filter element by sliding a sliding member against a rim of the filter element, To an air cleaner for a vehicle which is capable of closely fitting the rim of the element to the case in a very airtight manner.

Generally, automobiles generate power by mixing fuel and air and burning. That is, the fuel stored in the fuel tank of the automobile passes through various fuel supply devices, is mixed with the air introduced from the outside and is injected into the cylinder of the engine, and at the same time, the engine is operated while repeatedly sucking, compressing, As a result, the car gets power.

As described above, a certain amount of air is required to operate the engine, and the supply of such air flows from the outside of the vehicle. Air outside the vehicle flows into the air cleaner housing and is transferred to the intake manifold through the air intake hose connected to the air cleaner housing and supplied to the engine. The intake manifold is formed to allow air sucked from the outside through the air cleaner to pass through the filter to the opposite side. The dust and impurities contained in the air are filtered through the filter, and the purified air is supplied to the engine, To supply the necessary air.

The air cleaner includes a body having an air inlet formed at one side thereof, a cover coupled to an upper portion of the body and having a discharge port formed at one side thereof, and a filter element interposed between the body and the cover.

According to the structure of the air cleaner, when air flows into the air cleaner through the air intake port of the body, the introduced air is purified into the impurities through the filter element and then supplied to the engine through the exhaust port formed in the cover.

Since a large amount of impurities are adsorbed to the filter element when the air cleaner is used for a long period of time, the filter element installed in the body part and the cover part is replaced with a new filter element to filter the air after a predetermined time has elapsed.

On the other hand, in the conventional air cleaner for vehicles disclosed in Korean Patent No. 10-1318188, when the filter element installed on the body and the cover is replaced, eccentric cams of the height adjusting handle are rotated by gripping the handle of the height adjusting handle, The filter element is hermetically contacted to the body and the cover by raising the element upward so that the filter element is prevented from being shaken even when fluid pressure or vibration occurs in the air cleaner, thereby preventing occurrence of vibration sound.

However, even though the conventional air cleaner for a vehicle has a structure in which the handle is protruded from the end of the height adjusting handle, the narrow space between the cover and the body in the state where the filter element is inserted between the cover and the body, It is difficult to grasp the handle of the filter, and the rotation of the height adjustment handle is also not easy, so that it is very difficult to install the filter when replacing the filter element.

In addition, in the conventional air cleaner for a vehicle, the structure of the height adjusting handle and the structure for supporting and rotating the height adjusting handle is very complicated, so that the manufacturing cost is high and replacement of the filter element is troublesome.
