RELATED APPLICATIONS 
     This application claims priority to Chinese Patent Application 201811494692.4, filed on Dec. 7, 2018. Chinese Patent Application 201811494692.4 is incorporated herein by reference. 
     FIELD OF THE DISCLOSURE 
     The present disclosure relates to the field of bathroom fixtures, in particular to a water outlet device. 
     BACKGROUND OF THE DISCLOSURE 
     Existing water outlet devices, such as described in CN207119498U, comprise a body, a descaling needle plate disposed in the body, and a rotating member driven by water flow and rotating about an axial direction. The descaling needle plate and a water outlet cover are coaxially disposed, and the descaling needle plate has a plurality of needles. The descaling needle plate is oscillatingly connected with the rotating member. When water flows in the water outlet device, the water flow drives the rotating member to rotate, and the rotating member drives the needles to swing around the axial direction at a water outlet hole of the cover plate. The needles rub against scale attached to an inner side wall of the water outlet hole during the swinging process, so that the scale attached to the inner side wall of the water outlet hole falls off as the needles swings. The descaling needle plate can move toward and away from the cover plate. The needles of the descaling needle plate are inserted into the water outlet holes when the water is being discharged, and the needles pulls out of the water outlet holes when the water is turned off. The water exiting out of the water outlet holes has only a single water pattern (i.e., water outlet effect), and does not have different water patterns, so there is demand for improved water outlet devices.
