The upper end of the outer frame 1 is fitted around the periphery of the upper end cover 4, and the lower end of the outer frame 1 is fitted around the periphery of the lower end cover 5.

[0023] Reference Figure 3 and Figure 4 The upper end of the inner frame 2 is integrally provided with an upper mounting seat 6, and the lower end of the inner frame 2 is integrally provided with a lower mounting seat 7. The upper end of the filter element 3 is inserted into the upper mounting seat 6, and the lower end of the filter element 3 is inserted into the lower mounting seat 7. The lower end face of the upper cover 4 is provided with a first mounting ring groove 8 in the circumferential direction. The upper end of the upper mounting seat 6 is inserted into the first mounting ring groove 8. The upper end face of the lower cover 5 is provided with a second mounting ring groove 9 in the circumferential direction. The lower end of the lower mounting seat 7 is inserted into the second mounting ring groove 9. A sealing ring 10 is placed in the first mounting ring groove 8, and a sealing ring 11 is placed in the second mounting ring groove 9.

[0024] Four mounting posts 12 are evenly arranged circumferentially on the upper end of the upper mounting base 6. Each mounting post 12 includes a connecting post 13 and a locking block 14. The lower end of the connecting post 13 is integrally set on the upper end face of the upper mounting base 6, and the locking block 14 is integrally set on the upper end of the connecting post 13. The vertical cross-section of the mounting post 12 is convex. A fixing ring 15 is placed on the upper end face of the upper end cover 4. Four mounting holes 16 are circumferentially opened on the side wall of the fixing ring 15. Each mounting hole 16 includes a through hole 17 and a locking hole 18. The diameter of the through hole 17 is larger than the diameter of the locking hole 18. The through hole 17 and the locking hole 18 are interconnected. Four first through holes are circumferentially opened on the side wall of the sealing ring 10. Four second through holes are circumferentially opened at the bottom of the first mounting ring groove 8 on the upper end cover 4. The first and second through holes correspond to each other. The upper end of the locking block 14 passes through the first through hole, the second through hole and the through hole 17 in sequence. Then, the fixing ring 15 is rotated to allow the connecting post 13 to slide into the locking hole 18.

[0025] The locking block 14 has a guide surface 19 circumferentially provided on one end near the connecting post 13. Under the action of the guide surface 19, the mounting post 12 is then locked into the mounting hole 16, and the upper mounting seat 6 is inserted and fixed into the first mounting ring groove 8, which compresses the sealing ring 10.

The lower end cover 5 has a groove 21 circumferentially formed on the side wall of the second mounting ring groove 9. The groove 21 is annular, and the outer periphery of the snap fasteners 20 is engaged and fixed in the groove 21. When the lower mounting base 7 is inserted into the second mounting ring groove 9, the snap fasteners 20 are engaged in the groove 21, which compresses the sealing ring 11, thus ensuring a seal between the lower mounting base 7 and the lower end cover 5.

[0027] The inner walls at both ends of the outer frame 1 are integrally provided with ring blocks 22. The upper end cover 4 has a first annular groove 23 for the ring blocks 22 to be inserted into, and the lower end cover 5 has a second annular groove 24 for the ring blocks 22 to be inserted into. The outer frame 1 is composed of two half-frames 25. The two ends of the two half-frames 25 that are in contact with each other are provided with fixing holes. A connecting frame 26 is fixed through two adjacent fixing holes. The connecting frame 26 is in the shape of a "U". The two half-frames 25 are removed from the upper end cover 4 and the lower end cover 5 respectively. Then, the fixing ring 15 is rotated to allow the connecting post 13 to slide out from the locking hole 18 and into the through hole 17. Then, the fixing ring 15 is removed from the upper end cover 4. Then, the upper end cover 4 is removed from the multiple mounting posts 12. Finally, the lower mounting seat 7 is pulled out from the second mounting ring groove 9.
