Water outlet device

Abstract

A water outlet device includes a water-passing member having jet holes, a water outlet member having different water flow channels, a sliding block, and an elastic element that supports the sliding block in the axial direction. The water-passing member has a first limiting portion, and the water outlet member has a first supporting portion. The sliding block includes a second supporting portion and a second limiting portion. The first limiting portion is connected to the second limiting portion, such that the sliding block is only movable along the axial direction of the water outlet member. The second supporting portion presses against or separates from the first supporting portion, and the sliding block and the water outlet member can rotate relative to each other through the second supporting portion and the first supporting portion, such that the jet holes are in communication with the different water flow channels.
