Abstract: A shower head structure includes an outer housing, a water exciting vane wheel, a water outlet cover, and a water guide barrel. The outer housing contains a ball connector, and a sealing ring pressing the ball connector. The water exciting vane wheel includes a central hollow bushing, a plurality of curved vanes, and a catch plate. The water outlet cover defines multiple straight water outlet apertures and three massaging water outlet apertures and includes an annular water dispensing barrel provided with a short stub. The water guide barrel includes a first step provided with an enlarged opening tightly pressing the sealing ring and a second step provided with a reduced section provided with a vane wheel shaft extending through the hollow bushing of the water exciting vane wheel and defining a receiving hole securing the short stub of the water dispensing barrel. The reduced section of the water guide barrel defines three oblique cut water outlet ports facing the vanes of the water exciting vane wheel.
