[0037] A micro-pipe filter in the present embodiment achieves the purpose of filtering impurities in liquid or gas through the designed filter component 3. At the same time, the threaded connection design of the connecting rod 304 and the fixing sleeve 303 makes the replacement of the cylindrical filter element 305 simple and quick, reduces the maintenance cost, and improves the maintainability and use efficiency of the equipment. The sealing cover 8 arranged at the top of the filter tube 1 is in close contact with the upper sealing plug 301, which effectively prevents leakage problems during the filtering process, improves the sealing performance of the equipment, and ensures the stability and reliability of the filtering effect. The setting of the pull ring 9 makes it easier to remove the filter component 3. By squeezing the airbag 6 by the two squeezing tubes 5 close to each other, the airbag 6 can be in close contact with the external pipe to form a first sealing barrier. By cooperating with the external tie through the provided tie groove 10, the rubber tube 7 can be deformed and then in close contact with the external pipe to form a second sealing barrier, which effectively improves the overall sealing.

[0038] The working principle of the above embodiment is as follows: when liquid or gas passes through the filter tube 1, the impurities therein are first intercepted by the columnar filter core 305. The columnar filter core 305 is made of high-efficiency filter material and can effectively remove tiny particles in the fluid to ensure the purity of the fluid. The sealing cover 8 at the top of the filter tube 1 is in close contact with the upper sealing plug 301 to form a basic sealing structure to prevent the fluid from leaking from the top during the filtering process. The design of the squeeze tube 5 further enhances the sealing performance. The squeeze tube 5 can be rotated to move it toward the connecting tube 2, thereby compressing the airbag 6. After the airbag 6 is compressed, it will cling to the surface of the external pipe to form an additional The sealing layer effectively prevents fluid from leaking from the connecting pipe 2. The tie groove 10 is arranged to cooperate with the external tie to deform the rubber tube 7, and then closely contact with the external pipeline to form a second sealing barrier. When the cylindrical filter element 305 is blocked or damaged due to long-term use, it needs to be replaced. The user can release the threaded connection with the fixed sleeve 303 by rotating the connecting rod 304, and then pull the pull ring 9 upwards to remove the entire filter assembly 3 including the upper sealing plug 301, the connecting rod 304 and the cylindrical filter element 305 from the filter tube 1. After replacing the new filter element, the filter assembly 3 is reinstalled back into the filter tube 1.
