Technical Field
[0001] This utility model relates to the field of air filter housing technology, and in particular to an air filter housing that is easy to disassemble. Background Technology
[0002] The air filter housing is installed in the engine compartment to mount and secure the air filter. The air filter is one of the most important engine accessories, a device that removes particulate impurities from the air. When piston-driven machinery is operating, if the intake air contains dust, rainwater, sand, or other impurities, these impurities will accelerate the wear and tear on internal combustion engine parts such as cylinders and pistons. Therefore, an air filter is essential, and its structure, performance, and filtration effectiveness directly affect the user's maintenance schedule, costs, and engine lifespan.
[0003] Existing air filter housings typically prioritize aesthetics over appearance, often employing a retrofitted decorative cover to enhance the cleanliness of the engine compartment. However, this retrofit requires removing the cover before opening the air filter to replace the filter element, making maintenance inconvenient and increasing the risk of damage from frequent disassembly and reassembly. Furthermore, the four-point positioning system of these covers makes proper installation prone to causing rattling noises. Therefore, a more easily removable air filter housing is needed to address these issues. Utility Model Content
