Abstract

An outlet device that may be used in a shower head includes a base portion that is disposed with at least one inlet and a plurality of diversion holes. The base portion is disposed with a impeller. The impeller rotates when it is impacted by water flowing. A guard sheet is movably disposed in the base portion. The impeller is connected to the guard sheet in driving way so that the impeller rotates to drive the guard sheet to move. The guard sheet moves with respect to the base portion to control the diversion holes to outflow water in cycles intermittently. Each diversion hole is rotatably connected with an outlet nozzle. The impeller rotates to drive the outlet nozzles to rotate to outflow rotating water. The impeller and the outlet nozzles cooperate to achieve a rotating water with strong massage effect.
