[0016] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0017] Example 1: An air purifier filter element with deodorizing function, see Figures 1 to 3, comprising a lower connecting ring 1 and an upper connecting ring 11, a filter cartridge 12 is installed between the lower connecting ring 1 and the upper connecting ring 11, a fixing ring 2 is installed on the inner side of the upper connecting ring 11, a first mounting ring 3 is provided on the inner side of the fixing ring 2, and the outer side of the first mounting ring 3 is threadedly connected to the inner side of the fixing ring 2, a metal oxide catalyst cartridge 31 is installed at the bottom of the first mounting ring 3, a second mounting ring 4 is provided on the inner side of the first mounting ring 3, the outer side of the second mounting ring 4 is threadedly connected to the inner side of the first mounting ring 3, and a molecular sieve cartridge 41 is installed at the bottom of the second mounting ring 4; a chassis 7 is provided on the inner side of the lower connecting ring 1, a through hole 71 is opened on the chassis 7, and the through hole 71 is located in the middle of the chassis 7, and the bottoms of the metal oxide catalyst cartridge 31 and the molecular sieve cartridge 41 are both in contact with the surface of the chassis 7 When working, the dust in the air is filtered through the filter cartridge 12, and then the metal oxide catalyst cartridge 31 can promote the oxidation and decomposition of odor molecules in the air and convert them into harmless substances. The odor molecules that are not completely decomposed are then adsorbed by the molecular sieve cartridge 41, thereby greatly improving the filter element's odor-proof effect through double-layer deodorization, avoiding the problem that the filter element does not have the ability to deodorize and produce fresh air, and when the use time increases, the filter element itself has an odor and cannot deodorize itself, and the metal oxide catalyst cartridge 31 and the molecular sieve cartridge 41 can be independently disassembled and replaced by twisting the first mounting ring 3 and the second mounting ring 4. When the deodorization effect of one of the metal oxide catalyst cartridge 31 and the molecular sieve cartridge 41 is poor, it can be replaced independently without replacing the filter element as a whole, further reducing the cost of replacing the filter element.

[0018] For details, see Figure 3 , slots 8 are provided on both sides of the bottom of the chassis 7 and the bottom of the lower connecting ring 1. The two slots 8 on the same side are connected to each other, and a connecting plate 82 is provided between the two slots 8 on the same side. Fixing bolts 81 are passed through both sides of the surface of the connecting plate 82, and the two fixing bolts 81 are respectively threadedly connected to the bottom ends of the inner cavities of the two slots 8. The thickness of the connecting plate 82 is less than the depth of the slot 8. By twisting the fixing bolts 81, the chassis 7 can be easily disassembled and assembled, and the connecting plate 82 is completely received in the slot 8, avoiding the plate being placed on the outside of the chassis 7 after being connected to the chassis 7 and affecting the installation of the filter element.

[0019] For further information, see Figure 1 Finger holes 5 are provided on both sides of the surface of the first mounting ring 3 and the second mounting ring 4. The two finger holes 5 on the first mounting ring 3 and the two finger holes 5 on the second mounting ring 4 are symmetrically distributed. The setting of the finger holes 5 makes it easy for the staff to insert their fingers, and then makes it easy for the staff to manually rotate the first mounting ring 3 and the second mounting ring 4. Furthermore, there is no need to use tools to disassemble and assemble the first mounting ring 3 and the second mounting ring 4, making disassembly and assembly more convenient and quick.

[0020] It is worth noting that, see Figure 2 , the chassis 7 is fixedly connected to one end close to the molecular sieve cylinder 41 with a first rubber sealing ring, and the chassis 7 outside the first rubber sealing ring is fixedly connected to a second rubber sealing ring, and the first concave rubber sealing ring 61 and the second concave rubber sealing ring 6 correspond to the molecular sieve cylinder 41 and the metal oxide catalyst cylinder 31 respectively, the inner side size distribution of the first concave rubber sealing ring 61 and the second concave rubber sealing ring 6 is smaller than the wall thickness of the molecular sieve cylinder 41 and the metal oxide catalyst cylinder 31, and the first concave rubber sealing ring 61 and the second concave rubber sealing ring 6 are both elastic, and the first concave rubber sealing ring 61 and the second concave rubber sealing ring 6 can be tightly fitted to the outer side of the metal oxide catalyst cylinder 31 and the molecular sieve cylinder 41 after installation, thereby increasing the sealing performance of the connection between the metal oxide catalyst cylinder 31 and the molecular sieve cylinder 41 and the chassis 7, thereby improving the filtering and deodorizing effect of the filter element.
