Description

Technical Field

[0001] The invention relates to an air duct structure and a fan thereof, belonging to the technical field of fan equipment. Background Art

[0002] In air purification and ventilation systems, the effectiveness and reliability of screens are crucial as they are key components for filtering impurities and maintaining air quality. However, traditional screen designs often overlook flexibility and ease of maintenance during use, resulting in many challenges in practical applications. Specifically, after the screen has been working for a long time, dust and impurities are easily accumulated on the surface, and regular cleaning is required to maintain its filtration efficiency. However, in traditional designs, the cleaning process of the screen is often cumbersome and risky: on the one hand, the screen is usually fixedly installed, making it difficult to clean conveniently without disassembling the entire system; on the other hand, when the screen is disassembled for cleaning, the accumulated impurities are easily scattered into the air duct, which not only increases the difficulty of cleaning, but may also cause secondary pollution to the air duct system, affecting the overall operating efficiency and air quality. Therefore, a duct structure and its fan are proposed. Summary of the invention
