Two L filter holes 12 are provided at the top of the intercepting filter plate 8. The intercepting filter plate 8, the adsorption filter frame A9, the adsorption filter frame B10 and the adsorption filter frame C11 are all located inside the filter cartridge 2. The two positioning card plates 15 are respectively engaged with the two positioning grooves 7. The tops of the adsorption filter frames A9, B10 and C11 are all open-type designs. The bottoms of the adsorption filter frames A9, B10 and C11 are all provided with a plurality of water flow holes 16. The interiors of the adsorption filter frames A9, B10 and C11 are respectively filled with adsorption material layers A17, adsorption filter frames B10 and C11.
