[0021] Please refer to Figures 1-4This utility model provides a foldable filter, including a connecting frame 1. L-shaped grooves are formed on both the top and bottom sides of the connecting frame 1. Two symmetrical second connecting shafts 15 are slidably connected inside the L-shaped grooves. A folded filter belt 3 is connected between the two second connecting shafts 15. The top and bottom of the folded filter belt 3 are respectively fitted to the top and bottom of the inner cavity of the connecting frame 1. Positioning posts 16 are fixed to the top and bottom of the two second connecting shafts 15. A sliding top plate 2 is slidably inserted into the top of the connecting frame 1. A protrusion is provided at the bottom of one end of the sliding top plate 2. Two symmetrical positioning holes 17 are formed on the outer surface of the L-shaped groove at the bottom of the connecting frame 1. The bottom of the protruding end of 2 and the bottom of the other end of the sliding top plate 2 are both provided with another positioning hole 17, and the four positioning holes 17 are respectively slidably inserted into the interior of the four positioning holes 17. A plug 10 is slidably inserted into the interior of the L-shaped groove at the bottom of the connecting frame 1, and a notch is provided on one side of the plug 10. A fixed connecting box 5 and a first fixed block 4 are fixedly connected to one side of the connecting frame 1, and the top of the fixed connecting box 5 is provided with an opening. A second fixed block 12 is fixedly connected inside the fixed connecting box 5, and a sliding member 8 is slidably engaged inside the fixed connecting box 5. An elastic mechanism is provided between the bottom of the sliding member 8 and the second fixed block 12, and a push-pull plate 9 is fixedly connected to one side of the sliding member 8. The sliding member 8 is internally rotatably connected to a rotating shaft 22, and a rotating block 7 is fixedly sleeved on the outer surface of the rotating shaft 22. Both ends of the bottom of the sliding top plate 2 are fixedly connected to insert shafts 13, and both insert shafts 13 are slidably inserted into the top of the connecting frame 1. A square sliding opening is provided on one side of the connecting frame 1, and a first connecting shaft 6 is fixedly connected to one side of one insert shaft 13. One end of the rotating block 7 is rotatably connected to one end of the first connecting shaft 6. Through the connection of two second connecting shafts 15 with the folded filter belt 3, the two second connecting shafts 15 are slidably engaged inside the connecting frame 1, thereby completing the overall installation of the connecting frame 1. The sliding member 8, inside the fixed connecting box 5, relies on... The elastic sliding of the elastic mechanism allows the rotation of the rotating block 7 to be raised and lowered within the square sliding opening via the first connecting shaft 6. This, in turn, utilizes the sliding of the two insert shafts 13 on the top of the connecting frame 1 to raise and lower the sliding top plate 2. The raised and lowered position of the sliding top plate 2 is used to slide and position the two positioning posts 16, thus facilitating the stable positioning of the two second connecting shafts 15. This also facilitates the installation and removal of the folded filter belt 3. Furthermore, the sliding insertion of the plug 10 improves the sealing of the connecting frame 1, ensuring the filtration efficiency of the folded filter belt 3. This results in a device with strong filtration capabilities and easy disassembly and assembly of the folded filter belt 3, improving the efficiency of device replacement and maintenance.

[0022] It should be noted that the elastic mechanism mentioned in the above description includes a sleeve 18, one end of which is fixedly connected to a second fixing block 12, and a spring 19 is fixedly connected to one side of the inner cavity of the second fixing block 12.
