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.

A jet regulator (1) for use in a sanitary outflow fitting. The jet regulator (1) has a housing (2), a jet accelerator device (3), and a jet aeration device (5) which is mounted downstream of the jet accelerator device (3) in a flow direction (4). The stream aerating device (5) has a chamber (6) that has at least one aeration opening (7) through which air can be suctioned into the chamber (6) from the outside. An aperture plate (8) is arranged within the chamber (6), with the aperture plate dividing the chamber (6) into an air inlet part (9) and a mixing part (10), and air is suctioned from the outside in the air inlet part (9) and is mixed with liquid in the mixing part (10).

The invention relates to a jet regulator (1) having at least one jet splitter (2) which divides the inflowing waterflow, having a sleeve-shaped internal housing (3) which is encased by an external housing (4), and having at least one ventilation duct (5) which is disposed between the internal housing (3) and the external housing (4) and has at least one inflow opening (6) and at least one passage opening (7) which is provided on the housing circumference of the internal housing (3). It is a characteristic of the jet regulator (1) according to the invention that the at least one jet splitter (2) is configured as an atomizer nozzle which divides the inflowing waterflow into a substantially hollow-conical water jet, and that an impact zone (19) of an encircling annular shape is disposed in the flow direction below the at least one passage opening (7) on the internal circumference of the internal housing (3), the water jet divided so as to be hollow-conical impacting the housing internal circumference of the internal housing (3) in said impact zone (19) (cf. FIG. 2).

An aerator (1) having a housing (2) and a jet-splitting device (3) arranged or formed in the housing (2) for splitting an individual jet into a plurality of separate liquid components. The aerator (1) has at least two flow channels (4), which are oriented obliquely in such a way that the outlet directions (12) defined by the flow channels (4) meet each other. An insert part (5) is inserted into a hole (6) in the main body (28) of the jet-splitting device (3), which hole is oriented in particular in the longitudinal direction of the housing (2), such that the hole (6) is divided into the at least two obliquely extending flow channels.
