[0002] Cartridge filters are widely used for filtering liquids and gases, favored by many industries for their simple structure and high efficiency. These filters typically consist of a cylindrical outer shell and a filter medium within. Their design allows the fluid to flow evenly through the filter medium, effectively removing impurities. The filter medium can be made of metal mesh, fiber cloth, filter paper, or other suitable materials, depending on the size of the particles to be removed.

[0003] When replacing the filter element of the current cylindrical filter, it is necessary to manually remove the filter top cover, and then manually rotate the filter element fixed to the bottom of the top cover to disassemble it. However, when the filter element filters impurities, dust will accumulate on the outer surface of the filter element. When disassembling, the dust will be shaken off, causing pollution, which is very inconvenient to use.

[0004] To this end, we provide a filter element quick-disassembly structure for a cylindrical filter to solve the above problems. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

[0029] See also Figure 1-5 The utility model is a filter element quick-disassembly structure for a cylindrical filter, comprising a top cover 1, the bottom of the top cover 1 is connected to a connecting pipe 2, and a filter core 3 is arranged at the bottom of the connecting pipe 2; a shielding assembly is provided on the surface of the filter core 3, the shielding assembly comprises a telescopic cover 4, the telescopic cover 4 is sleeved on the surface of the filter core 3, the bottom of the telescopic cover 4 is fixedly connected to a bottom plate 5, and the bottom of the connecting pipe 2 is fixedly connected to a vertical rod 6; a fixing assembly is provided inside the bottom plate 5, the fixing assembly comprises a mounting block 7, the mounting block 7 is fixedly connected to the bottom of the filter core 3, a mounting hole 8 is opened inside the mounting block 7, and a limiting pin 9 is provided through one side of the bottom plate 5.

[0030] Specifically: the filter core 3 is made of non-woven fabric and high-quality modified activated carbon, which can filter tiny particles in the air, including pollen, industrial waste gas and dust. The top of the connecting pipe 2 is connected to a suction fan, which drives the air flow, and the filter core 3 filters the dust entering the bottom shell 12. The telescopic cover 4 is made of PVC film material and has a foldable and telescopic function. It can block and collect dust. The mounting hole 8 is opened inside the mounting block 7, and the filter core 3 can be fixed when the limit pin 9 is inserted into the mounting hole 8. Specific embodiment 2

[0032] See also Figure 1-5On the basis of the specific embodiment 1, the top of the filter core 3 is fixedly connected to a fixed tube 10, the surface of the fixed tube 10 is connected to the inner wall of the connecting tube 2 by a threaded connection, the bottom of the vertical rod 6 is fixedly connected to a retaining ring 11, and a bottom shell 12 is provided at the bottom of the top cover 1. A movable ring 13 is sleeved on the surface of the filter core 3, and the bottom of the movable ring 13 is fixedly connected to the telescopic cover 4. A first spring 14 is sleeved on the surface of the filter core 3, and the top and bottom ends of the first spring 14 are fixedly connected to the movable ring 13 and the bottom plate 5 respectively. A sliding rod 15 is fixedly connected to the inside of the bottom plate 5, and a moving block 16 is slidably connected to the surface of the sliding rod 15. One side of the moving block 16 is fixedly connected to the limit pin 9. A second spring 17 is sleeved on the surface of the sliding rod 15, and one end of the second spring 17 is fixedly connected to the moving block 16. A fixing groove 18 is provided on the top of the bottom plate 5, and a knob 19 is fixedly connected to one side of the limit pin 9.

[0033] Specifically: the surface of the fixed tube 10 is connected to the inner wall of the connecting tube 2 by a threaded connection, and the filter core 3 can be disassembled and assembled by rotational force. The inner diameter of the retaining ring 11 is larger than the filter core 3, and can be sleeved on the surface of the filter core 3. At the same time, it can push the movable ring 13 when moving downward. The first spring 14 and the second spring 17 both have the function of compressing energy storage. The first spring 14 can drive the movable ring 13 to move and reset the telescopic cover 4. The second spring 17 can reset the movable block 16. The diameter of the fixed groove 18 is the same as the diameter of the mounting block 7, which can facilitate the insertion of the mounting block 7 into the fixed groove 18.

[0034] The working principle of the utility model is as follows: when the filter core 3 needs to be installed, the staff holds the bottom plate 5 to drive the filter core 3 to move, and the filter core 3 drives the fixed tube 10 to insert the retaining ring 11 and continue to move upward;

[0035] When the bottom plate 5 moves upward, it drives the moving ring 13 to contact the retaining ring 11. At this time, the retaining ring 11 will limit the moving ring 13 from continuing to move upward, and the moving ring 13 pushes the telescopic cover 4 to shrink. When the telescopic cover 4 shrinks, it squeezes the first spring 14, so that the surface of the filter core 3 can be separated from the telescopic cover 4.

[0036] When the fixing tube 10 is inserted into the connecting tube 2, the bottom plate 5 is rotated to fix the fixing tube 10 to the connecting tube 2 through the locking action of the thread, as shown in FIG5 , and the installation of the filter core 3 is completed;

[0037] When the filter core 3 needs to be disassembled, the bottom plate 5 can be rotated in the opposite direction to separate the fixed tube 10 from the connecting tube 2, and then the filter core 3 is moved downward. At this time, the first spring 14 will reset the movable ring 13, and the movable ring 13 will drive the telescopic cover 4 to expand upward to shield the surface of the filter core 3, thereby preventing dust from falling when the filter core 3 is disassembled, thereby improving the practical effect.

[0038] After the filter core 3 is separated from the top cover 1, the filter core 3 can be moved to a dedicated cleaning room, and then the limit pin 9 can be manually pulled to disengage the limit pin 9 from the mounting hole 8, thereby canceling the fixation of the filter core 3. Then, the filter core 3 can be moved upward to disengage the mounting block 7 from the fixing groove 18, and the quick disassembly can be completed, making it convenient for the staff to clean the filter core 3.

[0039] The standard parts used in the present invention can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
