[0037] The control unit is arranged to control the opening and closing of the gas supply device 6 and the gas - liquid mixer 5, so that the water outlet control device 100 has a first water outlet mode and a second water outlet mode; wherein, in the first water outlet mode, the water inlet valve core 3 is opened, the gas supply device 6 and the gas - liquid mixer 5 are closed, and the water in the water flow channel flows out after passing through the gas - liquid mixer 5; in the second water outlet mode, the water inlet valve core 3 is opened, the gas supply device 6 and the gas - liquid mixer 5 are opened, and the gas - liquid mixer 5 mixes the gas entering from the air inlet 5012 and the water entering from the water inlet 5011 to generate bubble water, and the bubble water flows out from the fluid outlet 5013.

[0038] The water outlet control device 100 provided by the embodiments of the present application can be used in a shower, and of course can also be used in other water outlet devices. The water outlet control device 100 is set to have a first water outlet mode and a second water outlet mode, and users can select the water outlet mode according to their needs, so that users have different shower experiences. Among them, in the second water outlet mode, the gas-liquid mixer 5 mixes water flow and gas to generate a water flow rich in bubbles.
