Description

Technical Field

[0001] The utility model relates to the field of filter elements, in particular to an air filter element for automobiles. Background Art

[0002] An air filter element, also known as an air filter element, air filter cartridge or air filter, is a device that filters particulate impurities in the air. When the engine inhales a large amount of air during operation, if the air is not filtered, the dust in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Therefore, the air filter element plays a key role. After long-term use, the filter paper on the filter element will be clogged and the filter element needs to be replaced. However, the filter element is generally composed of a plastic frame and filter paper, in which the filter paper is fixed in the plastic frame and cannot be disassembled. The filter paper cannot be replaced separately, and the replacement cost is high. For this reason, an automotive air filter element is proposed. Utility Model Content
