Abstract
The present disclosure discloses a self-cleaning water outlet device, which comprises: a body, a deposit removal needle plate disposed in the body, a water outlet cover comprising a plurality of water outlet holes, and a rotatable member driven about an axial direction of the rotatable member by flowing water. An axial direction of the deposit removal needle plate and an axial direction of the water outlet cover are coaxial, and the deposit removal needle plate has a plurality of needles. The deposit removal needle plate is swingably connected with the rotatable member. When water flows into the water outlet device, the water flow drives the rotatable member to rotate, and the rotatable member drives each of the plurality of needles to swing about the axial direction of the deposit removal needle plate in a corresponding one of the plurality of water outlet holes.
