Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to an air filter element component which is easy to install. Background Art

[0002] The automobile air filter is a key component in the automobile engine intake system. Its main function is to filter the air entering the engine, remove dust, particles and other impurities in it, so as to ensure that the engine can inhale clean air. Automobile air filters are usually composed of a filter element and a housing. The filter element is the core part of the filter. Its material is mostly paper or fiber material, with high efficiency filtering performance. When air flows through the filter, the filter element can capture and block impurities in the air, allowing only clean air to pass through and enter the engine. The housing plays the role of protecting the filter element and fixing the installation. It is usually made of metal or plastic, with a solid structure and good sealing performance to prevent unfiltered air from bypassing the filter element and directly entering the engine. As the use time increases, the filter element will gradually accumulate impurities and the filtering effect will decrease. Therefore, regular replacement of the filter element is one of the important measures to maintain engine performance. In the existing patent application with application number CN202022505095.6, an air filter that is easy to replace the filter element is proposed. However, since its box body and upper cover are connected and fixed by a number of bolts, the bolts need to be installed one by one when installing and fixing the filter element. This process is relatively cumbersome, which makes it inconvenient to install and fix the filter element, and ultimately makes the installation and fixation efficiency of the filter element low. Therefore, an air filter element assembly that is easy to install is proposed to solve the above problem. Utility Model Content
