Abstract

An integrated waterway assembly of a reverse osmosis (RO) water filtration device includes a main body, a shut off valve, a mounting shelf, a top cover, a bottom cover and a fixing ring. Water to be filtered sequentially goes through a water inlet, a shut off valve, a RO cartridge joint and a check valve, and a filtered water outlet on the main body to get the water filtered. The RO cartridge joint on a bottom portion of the main body is connected with a RO cartridge, and water enters the RO cartridge and further flows through the RO cartridge joint to get the water filtered. Given the foregoing structure, the water filtration device is structurally compact and integrated and has less water leakage.
