The invention discloses a rotary massage water outlet mechanism. The rotary massage water outlet mechanism comprises a water outlet base and a water inlet cover. The water outlet base is provided with a water outlet pore channel. The water inlet cover is provided with a water inlet. A containing cavity is formed in the water outlet base. A water jetting plate, a rotating shaft, an impeller and a water outlet core are arranged in the containing cavity. A water jetting opening is obliquely formed in the water jetting plate, and the water jetting opening communicates with the water inlet. The impeller is arranged between the water outlet core and the water jetting plate through the rotating shaft, and water passing openings are formed between all blades of the impeller. The water outlet core is arranged in the water outlet pore channel located under the impeller, and oblique flow passes are formed on the periphery of the water outlet core. According to the rotary massage water outlet mechanism, the structure is simple, and the number of parts is small; the impeller rotates to be matched with the rotating water outlet core, water is thrown out by the oblique flow passes to form annular particle water, the size of annular area of annular particle water spots and the size of water particles can be changed in a circulating mode, and thus one sort of water spots can achieve change of different forms.
