[0033] See Figure 1-13 As shown in the figure, as an embodiment of the present invention, a detachable filter cartridge is provided, specifically a detachable filter cartridge for an air filter, comprising a cartridge body and filter media 4. The cartridge body includes a body 3 and a first cover 1 and a second cover 2 detachably mounted at opposite ends of the body 3. A first receiving cavity 5 is formed between the first cover 1 and the body 3, and a second receiving cavity 6 is formed between the second cover 2 and the body 3. The first receiving cavity 5 and the second receiving cavity 6 are interconnected. The filter media 4 is detachably mounted in the first receiving cavity 5 and the second receiving cavity 6, respectively. The filter cartridge of the present invention features a detachable, separate design for the cartridge body and the filter media 4, allowing the filter media 4 to be individually removed from the cartridge body for replacement when its lifespan expires, without needing to replace the entire filter cartridge. This achieves repeated recycling of the cartridge body, avoids resource waste, and reduces replacement costs. Simultaneously, it can accommodate various types of filter media 4 to meet the needs of different users.

[0034] In this embodiment, a plurality of first snap fasteners 7 are provided on the lower periphery of the first lid 1, and a plurality of first slots 8 are provided on the periphery of the box body 3 near the end of the first lid 1. The first snap fasteners 7 and the first slots 8 are locked together to realize the detachable installation of the first lid 1 on the upper end of the box body 3. This setting makes the disassembly and assembly of the first lid 1 more convenient and quick, thereby enabling the filter material 4 in the first receiving cavity 5 to be quickly replaced. Specifically, the first snap fastener 7 includes a first elastic plate 71 extending downwards, a limiting block 72, and a first latch 73. The limiting block 72 is located on the outer side of the middle part of the first elastic plate 71, and the first latch 73 is located on the outer side of the bottom of the first elastic plate 71. The first slot 8 includes an upward-opening U-shaped latch 81 and a first latching hole 82 located below the U-shaped latch 81. The limiting block 72 abuts against and is limited at the bottom of the U-shaped latch 81. The first latch 73 and the first latching hole 82 are locked together. This arrangement makes the assembly of the first box cover 1 more secure and stable. The user's hand can press the first elastic plate 71 at the U-shaped latch 81 to make the first elastic plate 71 elastically deform inward, thereby allowing the first latch 73 and the first latching hole 82 to be easily and quickly released from the locking engagement, so that the first box cover 1 can be easily removed from the box body.

[0035] In this embodiment, the second cover 2 is provided with a plurality of second slots 10 on its periphery, and the box body 3 is provided with a plurality of second spring buckles 9 on the periphery side wall near the end of the second cover 2. The second spring buckles 9 are engaged with the second slots 10 to enable the second cover 2 to be detachably installed at the lower end of the box body 3. This arrangement makes the disassembly and assembly of the second cover 2 more convenient and quick, thereby enabling the filter material 4 in the second receiving cavity 6 to be quickly replaced. Specifically, the second snap fastener 9 includes a downwardly extending second elastic plate 91 and a second latch 92 disposed on the outer side of the second elastic plate 91. The second slot 10 includes a vertically extending clearance hole 101 and a movable slot 102 connected to the bottom of the clearance hole 101. The outer side and bottom side of the movable slot 102 are open. The second latch 92 is locked to the top wall of the movable slot 102. The bottom of the second elastic plate 91 is exposed in the movable slot 102, so that the user's hand can press the second elastic plate 91 inward at the movable slot 102 to make the second elastic plate 91 elastically deform inward. This allows the second latch 92 to easily and quickly release the locking engagement with the top wall of the movable slot 102, thereby easily removing the second cover 2 from the box body.

[0036] In this embodiment, both the first lid 1 and the second lid 2 are hollowed-out lids. The box body 3 includes a box body wall 31 with a rounded rectangular cross-section and a hollowed-out grid frame 32 disposed within the box body wall 31. The first receiving cavity 5 and the second receiving cavity 6 are located on both sides of the grid frame 32 and are connected through the grid frame 32. This structure makes the filter box's body structure simple and easy to clean. Sealing cotton 11 is installed on the outer circumferential side of the box body wall 31 to achieve a sealing assembly.

[0037] In this embodiment, the filter material 4 in the first receiving cavity 5 is filter cotton, and the filter material 4 in the second receiving cavity 6 is particulate filter material. The upper and lower ends of the second receiving cavity 6 are respectively detachably installed with an upper filter screen 12 and a lower filter screen 13. The particulate filter material is activated carbon or zeolite placed between the upper filter screen 12 and the lower filter screen 13, thereby ensuring the air filtration and purification effect.

[0038] See Figure 12 and 13 The diagrams show the structures of the upper filter 12 and the lower filter 13 (mesh size not shown). In this embodiment, the upper filter 12 has upper insert blocks 121 around its perimeter, and an upper slot 14 is provided on the inner wall of the box body 31 at the end of the grid frame 32 facing the second receiving cavity 6. The upper insert blocks 121 and the upper slot 14 are inserted into each other to allow the upper filter 12 to be detachably installed at the upper end of the second receiving cavity 6. The lower filter 13 has lower insert blocks 131 around its perimeter, and a lower slot 15 is provided on the circumferential inner wall of the second box cover 2. The lower insert blocks 131 and the lower slot 15 are inserted into each other to allow the lower filter 13 to be detachably installed at the lower end of the second receiving cavity 6, ensuring assembly stability and facilitating disassembly for replacement or cleaning. The mesh size and material of the upper and lower filters 13 can be adjusted according to different environments and different filter materials. For example, changing to a filter material with a mesh size of 40 or less can adapt to filter materials that easily generate powder from particulate matter; changing to a filter material with a mesh size of 40 or more can adapt to filter materials that allow for ventilation of large particles; changing to a wire mesh can adapt to environments with added UV lamps, etc.
