PURPOSE: A leakage prevention filter cartridge is provided to not allow a burr, which is generated when a filter head and a filter body are combined, to escape to the outside of a filter cartridge and to minimize generation of leakage in a state that a filter cartridge and a cap are combined. Also, leakage of a product can be authentically determined in a product inspecting step, a cost for after service can be reduced, and a production cost can be saved. CONSTITUTION: A leakage prevention filter cartridge comprises a filter head(110); and a filter body(150). The filter head has a first water moving hole(121) and a second water moving hole that is formed on the outside compared to the first water moving hole. Water flows in through one of the moving holes, and the water is flowed out through the other moving hole. A filtration part(158) is equipped inside the filter body. An outer Rim(133) having a ring shape and extended to a lower direction and a inner Rim(134) that is inwardly separated from the outer Rim are formed at a lower part of the filter head. The filter body has a center Rim(156) that is inserted between the outer Rim and the inner Rim. Also, the filter body is in contact with an outer periphery of the outer Rim and includes an upper wall phloem(152) that is extended upwardly. The filter head comprises a shield ring(136) that is separated from the outer Rim at a certain distance and formed at an upper part of the outer Rim in a ring shape. The shield ring contacts an inner periphery of the upper wall phloem. |
