Abstract: A shower head structure includes a front cover disc, a water outlet disc, a joint base, a water stopper body and a water stopper. The shower head body is installed to the joint base, and the water stopper body is connected to the water outlet disc, and the water stopper is installed into the hollow hole of the water stopper body. When water flows into the shower head body, the water pressure pushes the water stopper and the water gasket to block the hollow hole and stop water coming out from outlet disc, but the water will come out from the periphery of the water stopper body instead. If an accessory is installed, the water stopper is pushed to interconnect a passage, so that the water will be supplied to the accessory from the middle of the front cover disc to produce a variety of splashes.
