Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
referring to fig. 1-6, the air filter assembly mainly comprises an air filter upper cover 1, an air filter middle cover 2, an air filter base 3, a foam filter element 4, a paper filter element 5, a bolt and nut assembly 7, a seal ring 8, a base decorative plate 9, a round head cross screw 10 and an upper cover decorative plate 11.
The upper cover 1 of the air filter, the middle cover 2 of the air filter and the base 3 of the air filter are sequentially connected from top to bottom to form a shell of the air filter. A foam filter element 4 and a paper filter element 5 are arranged in a cavity enclosed by the upper cover 1 of the air filter and the middle cover 2 of the air filter. The paper filter element 5 usually adopts filter element paper (UV full-glue paper) + PVC.
