Gas-liquid mixing filter element

The gas-liquid mixing filter element comprises an upper cover, a lower cover, a filter element shell, a central pipe and a central connector, the upper cover and the lower cover are detachably connected to the upper end and the lower end of the filter element shell respectively, the central pipe is arranged in the filter element shell, and a plurality of hollow fiber membrane filaments are arranged on the outer side of the central pipe in the circumferential direction. A plurality of small holes are formed in the side walls of the hollow fiber membrane filaments. According to the gas-liquid mixer, the gas-liquid mixing filter element can be simply and quickly disassembled and assembled, and the problem that the hollow fiber type gas-liquid mixer is difficult to replace by a user when being blocked is solved; the filter element disclosed by the utility model is highly integrated, small in size and small in occupied space, and the size of equipment using the gas mixing filter element can be effectively reduced;
