A cam bushing, a cam, a movable tile and a stationary tile are mounted inside the shell. A central portion of the cam is pivotally mounted to the cam bushing and a top portion protrudes beyond the top opening of the shell and is connected to a handle. The movable tile has a cam opening formed through the movable tile for the bottom portion of the cam to be inserted therein. Five water paths formed through the stationary tile and the movable tile and are respectively connected with three water inputs and two water outputs. The water purification core valve is operated by pivoting the handle to align the water paths to corresponding water supply, thereby fulfilling control over three ways of water input and two ways of water output. 1.
