ABSTRACT:
An intersecting water conducting filter including a filter main body. An oblique tapered assembly chamber is formed in the filter main body. A sidewall of the assembly chamber is formed with multiple insertion grooves in each of which a water conducting layer is inlaid. Each water conducting layer is composed of a partitioning board and a filtering cotton. The partitioning board of each water conducting layer is formed with one or more conducting holes at different intervals. When water flows through the conducting holes, an intersecting conducting effect is provided for the water flow so that the water can fully flow through the Far-infrared precision ceramic/porcelain particle layer, KDF copper/zinc filtering layer, calcium sulfite layer and coconut shell activated carbon layer installed between the water conducting layers. The filter main body has a first end formed with inner thread for connecting with a shower sprinkler, an intake controller or a water inlet end. A second end of the filter main body is formed with outer thread for connecting with an outlet conduit.
