[0002] Replacing an air purifier's filter typically requires the user to manually open the unit's casing, remove the old filter, and install a new one. This process is not only time-consuming and labor-intensive, but can also easily release dust and bacteria from the unit into the air, affecting air quality. Furthermore, since installing and removing the filter requires skill and strength, it can be difficult and risky for the elderly and children. Therefore, a mechanism has been designed to facilitate the ejection of the air purifier's filter, making it easier to replace. Summary of the Invention
