摘要： The present disclosure discloses a water outlet device comprising a water outlet portion and a moving portion disposed in the water outlet portion. The water outlet portion comprises a body portion and a cover portion. The cover portion comprises a first water outlet nozzle, and the moving portion is movable relative to the cover portion. A transmission mechanism is disposed between the moving portion and the water outlet portion, and the transmission mechanism drives the moving portion to move toward the cover portion and away from the cover portion. The moving portion comprises an insertion portion. Movement of the moving portion controls the insertion portion to insert or pull out from the first water outlet nozzle, and the first water outlet nozzle discharges different water spray patterns when the insertion portion is inserted into or pulled away from the first water outlet nozzle.

摘要： 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.

摘要： The present disclosure discloses a water outlet mechanism and a shower head comprising the water outlet mechanism. The water outlet mechanism comprises an inlet, an air intake chamber, an air intake passage, and a water outlet passage. The water outlet passage is in communication with the air intake chamber, and the air intake chamber is disposed with a wall connected to an entrance of the water outlet passage. The water outlet passage gradually increases in a downward direction, and a plurality of rectifying ribs protrude from an inner wall of the water outlet passage and are arranged in a circumferential direction at intervals. When the water flows through the inlet and enters the air intake chamber, a flowing cross sectional area of the water changes suddenly, an air pressure surrounding the water is less than the external air pressure, and a negative pressure is generated in the air intake chamber.
