[0021] Please see Figures 1-4 The filter cartridge structure for rapid filtration in this embodiment includes a filter cartridge 1, a connecting cylinder 3 fixedly connected to the left side of the filter cartridge 1, a threaded disc 4 threadedly connected to the right side of the filter cartridge 1, a filter cartridge 5 disposed on the right side of the threaded disc 4, a cleaning component 7 movably installed inside the filter cartridge 5, and a first filter layer 8, a second filter layer 9, a third filter layer 10 and a fourth filter layer 11 threadedly connected inside the filter cartridge 1.

[0022] The cleaning component 7 includes a rotating ring 701, which is movably mounted on the outer surface of the connecting cylinder 3. A rotating shaft 702 is fixedly connected inside the rotating ring 701. A plug rod 703 is fixedly connected to the right end of the rotating shaft 702. A plug shaft 705 is movably mounted inside the filter cylinder 5. A cleaning plate 704 is fixedly connected to the outside of the plug shaft 705.

[0023] In the implementation of the case, by setting up filter cartridge 1, the filter cartridge 5 is threadedly installed to filter cartridge 1. The air is first filtered through multiple layers by filter screen 12, thereby filtering out large impurities in the air. The air enters the interior of filter cartridge 1 through through hole 17 and is filtered sequentially through fourth filter layer 11, third filter layer 10, second filter layer 9 and first filter layer 8. Fourth filter layer 11 is a cotton fiber filter, third filter layer 10 is a filter paper filter, second filter layer 9 is a HEPA filter, and first filter layer 8 is an activated carbon filter. Multi-layer filtration can achieve fine filtration of air.

[0024] In the implementation of the case, by setting up the cleaning component 7, by rotating the rotating ring 701, the rotating ring 701 will drive the rotating shaft 702 to rotate, and the rotating shaft 702 will synchronously drive the plug rod 703 to rotate. The plug rod 703 is inserted into the inside of the plug shaft 705, thereby driving the plug shaft 705 and the cleaning plate 704 to rotate. The cleaning plate 704 can then scrape and clean the surface of the filter screen 12, thereby facilitating the cleaning of the filter screen 12 and improving the air filtration efficiency of the filter screen 12.

[0025] In the case implementation, by setting the first limit bar 13, the connecting cylinder 3 and the filter element cylinder 1 are inserted into the cleaning device, so as to realize the quick installation and disassembly of the filter element cylinder 1 and the filter cylinder 5.

[0026] In the implementation of the case, by setting the second limiting bar 14, the plug rod 703 is inserted into the limiting groove 16 through the second limiting bar 14, so as to realize the connection between the plug rod 703 and the plug shaft 705, and install and connect the filter cylinder 5.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, thread the fourth filter layer 11, the third filter layer 10, the second filter layer 9 and the first filter layer 8 into the inside of the filter cartridge 1;

[0029] 2) Then, the filter cylinder 5 and the filter element cylinder 1 are installed and connected by the threaded disc 4;

[0030] 3) Then install the connecting cylinder 3 using the first limiting strip 13;

[0031] 4) Finally, the filter cartridge 5 is cleaned using the cleaning component 7.

[0032] In summary, this rapid filtration filter structure, by setting up the filter cartridge 1, allows for multi-layer filtration of air by threading the filter cartridge 5 to the filter cartridge 1 during use. First, the air undergoes multi-layer filtration through the filter screen 12, thus filtering out large impurities. The air then enters the interior of the filter cartridge 1 through the through-hole 17, passing sequentially through the fourth filter layer 11, the third filter layer 10, the second filter layer 9, and the first filter layer 8. The fourth filter layer 11 is a cotton fiber filter, the third filter layer 10 is a filter paper filter, the second filter layer 9 is a HEPA filter, and the first filter layer 8 is an activated carbon filter. This multi-layer filtration achieves meticulous air filtration.

[0033] Furthermore, by setting up the cleaning component 7, rotating the rotating ring 701 will drive the rotating shaft 702 to rotate, and the rotating shaft 702 will synchronously drive the plug rod 703 to rotate. The plug rod 703 is inserted into the plug shaft 705, thereby driving the plug shaft 705 and the cleaning plate 704 to rotate. The cleaning plate 704 can then scrape and clean the surface of the filter screen 12, thereby facilitating the cleaning of the filter screen 12 and improving the air filtration efficiency of the filter screen 12.
