A water purification machine comprises a casing, a filtering system mounted on the casing, a booster pump, a water inlet solenoid valve, a control part and various joints for connection, and is characterized in that the filtering system comprises filter elements and end covers, filter element barrels for accommodating the filter elements are formed in the casing, ports connected with the corresponding joints on a pipeline are formed in the lower ends of the filter element barrels, and the end covers are located outside the casing and are detachably and rotationally connected and fixed with the filter element barrels. The water purification machine has the advantages as follows: the filter element barrels capable of accommodating the filter elements are formed on the casing, the end covers are arranged outside the casing and are detachably and rotationally connected with the filter element barrels, when the filter elements are required to be changed, all that is required is to unscrew the end covers directly,
