the water inlet condition comprises at least one of a flow volume or whether water is flowing or not flowing,
the control mechanism controls the water inlet condition of each of the at least two water inlets to enable the water outlet nozzle to discharge the different water sprays,
a flow direction of a first water inlet of the at least two water inlets is disposed along a direction tangent to the water outlet to enable water from the first water inlet to flow into the water outlet nozzle to generate a vortex,
a flow direction of a second water inlet of the at least two water inlets intersects with an axial direction of the water outlet nozzle, and
a bottom surface of the first water inlet is lower than a bottom surface of the second water inlet.

2. The water outlet device according to claim 1 , wherein a linear extension of the first water inlet is disposed on a front side of the second water inlet.

3. The water outlet device according to claim 1 , wherein the flow directions of the at least two water inlets are disposed on a same plane.

4. The water outlet device according to claim 1 , wherein the flow directions of the at least two water inlets intersect.

5. The water outlet device according to claim 1 , wherein a plane disposed with the flow directions of the at least two water inlets is perpendicular to the axial direction of the water outlet nozzle.

6. The water outlet device according to claim 1 , comprising:
an installation portion, wherein:
