Automobile filter element

Abstract

The invention relates to an automobile filter element which comprises a hollow cylindrical body and a frame, wherein the hollow cylindrical body is formed by longitudinally folding filter paper, the frame is arranged at the hollow inside of the body, and both axial ends of the body are respectively provided with two annular end surfaces. The invention is characterized in that the two annular end surfaces are respectively stuck with an end cover which is made of a non-woven fabric. In the technical scheme, the end cover is made of a non-woven fabric, thereby saving the material cost; since the non-woven fabric, which has favorable sealability and corrosion resistance, is directly attached to the annular end surface, the automobile filter element is more convenient for machining; since the non-woven fabric also has water resistance, the joints of the end covers and the frame do not need seal rings; and in addition, flanges, which bend to the filter paper and are coated on both ends of the filter paper, are not needed, thereby increasing the filtration area of the filter paper and enhancing the filtration effect.

Description

technical field [0001] The invention relates to the field of automobile filter equipment, in particular to an automobile filter element. Background technique [0002] During the operation of the automobile engine, air needs to be burned, and the air usually contains foreign matter such as sand, dust and water vapor, which causes many problems: 1. When the foreign matter enters the cylinder block of the engine, it is easy to cause the wear of the cylinder block; 2. 1. If the volume of the foreign matter is large, it may block the engine throttle body, causing the valve body to not work smoothly; 3. When the foreign matter enters the engine oil, it may cause serious wear and tear between the friction pairs of the engine as a whole. Therefore, a filter is usually installed in front of the car engine, and the filter element is the main part of the filter. The traditional car filter element usually includes a hollow cylindrical body made of longitudinally folded filter paper mate...

Problems solved by technology

[0002] During the operation of the automobile engine, air needs to be burned, and the air usually contains foreign matter such as sand, dust and water vapor, which causes many problems: 1. When the foreign matter enters the cylinder block of the engine, it is easy to cause the wear of the cylinder block; 2. . If the volume of the foreign matter is large, it may block the engine throttle valve body, causing the valve body to not work smoothly; 3. When the foreign matter enters the engine oil, it may cause serious wear between the friction pairs of the engine as a whole

This technical solution has the following defects: 1. The material cost of the iron frame and the iron end cover is relatively high; 2. The body, the iron frame and the iron end cover need to be manually assembled. In today's society where labor costs are constantly rising, the production cost of enterprises has increased; 3. The iron frame and iron end cover have poor corrosion resistance; 4. A sealing ring needs to be added at the joint between the iron frame and iron end cover to improve filtration 5. The iron end cover also needs to be provided with folded edges that bend towards the filter paper and cover both ends of the filter paper, which reduces the filter area of ​​the filter paper and thus reduces the filter effect of the filter.
