PROBLEM TO BE SOLVED: To exchange a check valve more surely and easily, which is arranged on a water pipe or a supply pipe when a cartridge type water purifier is installed, by reducing troubles to zero when the check valve is inspected or repaired. SOLUTION: The cartridge type water purifier is provided with: a base body having an inflow port and an outflow port; a case body having a drum casing; an inflow port and an outflow port which respectively communicate with the inflow port of the base body and the outflow port thereof; and a cartridge filter body which is inserted and fixed in the case body to be exchanged freely and used for purifying the water flowing through an inflow port of the cartridge filter body and delivering the purified water through an outflow port of the cartridge filter body. A check valve mechanism is formed integrally with the cartridge filter body at one or both of the inflow port and the outflow port of the cartridge filter body. COPYRIGHT: (C)2007,JPO&INPIT
