Description

Technical Field

[0001] The utility model belongs to the technical field of filter elements, and particularly relates to an activated carbon filter element which is easy to replace. Background Art

[0002] The activated carbon filter is an important part of the filter. It is made of high-quality fruit shell charcoal and coal-based activated carbon and processed with high-tech technology. The activated carbon filter integrates adsorption, filtration, interception and catalysis, and can effectively remove organic matter, residual chlorine, odor, radioactive substances and other impurities in the water. The powerful adsorption capacity of the activated carbon filter enables it to remove rust, odor and other bad odors in the water, significantly improving the water quality.

[0003] At present, when the existing filter is in use, the filter element will absorb a large amount of impurities, which causes the performance of the filter element to decrease as the impurities increase. In addition, the fixed installation method makes it difficult to replace the filter element, which is not conducive to maintaining the long-term performance of the filter.

[0004] In order to solve the above problems, the present application proposes an activated carbon filter element which is easy to replace. Utility Model Content

[0010] Furthermore, a protruding plug rod is provided at one end of the fixing rod, and a positioning hole for the plug rod to be snap-connected is provided inside the boss.

[0011] Furthermore, both upper and lower ends of the filter element are provided with adsorption cotton for resisting against the outer surface of the rotating rod to form a seal, and the adsorption cotton is also used to wrap the centrifugal blades to clean their surfaces.
