two water dividing passages, and
a valve core, wherein:
the water outlet component comprises a spherical chamber,
a bottom of the spherical chamber comprises a water outlet hole,
a top of the spherical chamber comprises a first water inlet,
a side wall of the spherical chamber comprises a second water inlet,
discharging water spray from the water outlet hole is controlled by flow rate variations of the first water inlet and the second water inlet,
the two water dividing passages are respectively in communication with the first water inlet and the second water inlet, and
the valve core is disposed between the water inlet passage and the two water dividing passages to cooperate with the first water inlet and the second water inlet to steplessly adjust the flow rate variations of the first water inlet and the second water inlet.

2. The water outlet device according to claim 1 , wherein a variation between a cross-sectional area of the first water inlet and a cross-sectional area of the spherical chamber becomes larger as the first water inlet approaches the spherical chamber.

3. The water outlet device according to claim 1 , wherein:
a midmost point of the top of the spherical chamber comprises the first water inlet, and
a midmost point of the bottom of the spherical chamber comprises the water outlet hole.

4. The water outlet device according to claim 1 , wherein the second water inlet is laterally disposed on an upper half of the side wall of the spherical chamber.

5. The water outlet device according to claim 1 , wherein an inner port of the second water inlet is tangentially disposed to discharge vortex water.

6. The water outlet device according to claim 1 , comprising:
