Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon filter elements, in particular to a modified activated carbon filter element. Background Art

[0002] The activated carbon filter element is made of high-quality fruit shell charcoal and coal-based activated carbon, supplemented with food-grade adhesives, and processed by high-tech technology and special processes. It integrates adsorption, filtration, interception, and catalysis. It can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the effect of decolorization and removal of odor. It is an ideal new generation product in the liquid and air purification industry. Types: white head sintered activated carbon filter element, black head with skeleton sintered activated carbon filter element, granular activated carbon filter element.

[0003] The longer the activated carbon filter currently used is used, the yellower the sponge inside becomes, and the worse the filtering effect becomes. Therefore, the sponge needs to be replaced regularly. However, the outer shell that protects the filter element appears to be one-piece in front of non-technical personnel. Therefore, every time the outer shell is opened, it will be violently broken and then the outer shell will show varying degrees of damage, resulting in the filter element that has been replaced with the sponge being unable to continue to be used. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0007] By adopting the above technical solution, when replacing the sponge, the user loosens the strap buckled with the protrusion, and then the rubber ring becomes loose, and then inserts one end of the external tool (crowbar) into the annular gap from the slope, and then prys the crowbar to move the ring body toward the end cover. After the ring body passes the protrusion, the user can easily remove the end cover, and then use tweezers or two fingers to pinch out the sponge to complete the replacement. This is a non-violent replacement, which ensures the service life of the product.

[0015] 1. In the utility model, when replacing the sponge, the user loosens the strap buckled with the convex point, and then the rubber ring becomes loose, and then inserts one end of the external tool (crowbar) into the annular gap from the slope, and then prys the crowbar to move the ring body toward the end cover. After the ring body passes the convex point, the user can easily remove the end cover, and then use tweezers or two fingers to pinch out the sponge to complete the replacement. Non-violent replacement ensures the service life of this product.

[0016] 2.
