Compared with existing techniques, the technical solution provided by the present disclosure has the following advantages.

The water outlet component comprises the spherical chamber. The bottom of the spherical chamber comprises the water outlet hole, the top comprises the first water inlet, and the side wall comprises the second water inlet. First, the first water flow from the first water inlet flows into the spherical chamber, and kinetic energy and flow speed are increased due to Bernoulli effect. When the water flow rushes into the spherical chamber, a small portion of the water flow will be adhered to a chamber wall due to wall-adherence effect, the water flow for wall-adherence in all directions varies at each water inflow moment due to turbulence instability and will impact a main waterway of the first water flow to deflect the main waterway when a flow rate for the wall-adherence is large. Therefore, a circumferentially oscillating pulsating water spray is generated, dynamic shaking water effect is achieved, water spray is fuller, discharging water is more uniform, and massaging feeling is remarkable. Second, the water flow can be discharged from a whole surface cover. Third, water spray from the water outlet hole is controlled by flow rate variations of the first water inlet and the second water inlet, so that a stepless variation of the water spray from the same water outlet hole is achieved.

When the first water inlet approaches the spherical chamber, a sudden change between cross-sectional areas becomes larger, and the Bernoulli effect is good.

The driving mechanism comprises the gear rack, the push button, the first transmission gear and the speed reduction mechanism. The push button drives the gear rack to move and drives gears to rotate. The speed reduction mechanism drives the valve core to rotate and drives the valve core to rotate back and forth synchronously to make flow rates of the two water inlets change, so that the stepless variation of the water spray from the same water outlet hole is achieved.

The second water inlet is disposed on the upper half of the side wall of the spherical chamber and is laterally disposed, so that vortex rotating water is generated when water flows into the spherical chamber.

The inner chamber wall of the control chamber comprises an arc-shaped surface, and the two water dividing holes are disposed on the arc-shaped surface and are disposed circumferentially. The valve sheet defines the arc-shaped surface. The valve sheet is rotatably connected to the inner side of the control chamber and cooperates with the arc-shaped surface of the inner chamber wall. The adjustment is convenient, and the structure is compact.

The water divider comprises the upper chamber of the spherical chamber, and the surface cover comprises the lower chamber of the spherical chamber. The water divider and the surface cover are fixedly connected together, and the upper chamber and the lower chamber cooperate to define the spherical chamber. The second water dividing chamber in communication with the second water inlet is defined between the water divider and the surface cover, and the first water dividing chamber in communication with the first water inlet is defined between the fixed base component and the water divider.

Referring to <FIG>, a water outlet device comprises a water outlet component <NUM>, a control mechanism <NUM>, a water inlet passage <NUM> and two water dividing passages <NUM>. The water outlet component <NUM> comprises a spherical chamber <NUM>. A center of a bottom of the spherical chamber <NUM> comprises a water outlet hole <NUM>, and a center of a top of the spherical chamber <NUM> comprises a first water inlet <NUM>. The first water inlet <NUM> is directly opposite to the water outlet hole <NUM>. When the first water inlet <NUM> approaches the spherical chamber <NUM>, a sudden change between cross-sectional areas is large, and a cross-section of the first water inlet <NUM> is gradually enlarged in a downward direction. A first water flow from the first water inlet <NUM> flows into the spherical chamber <NUM>, and kinetic energy and flow speed are increased due to Bernoulli effect. When water flow rushes into the spherical chamber <NUM>, a small portion of the water flow A2 will be adhered to a chamber wall due to wall-adherence effect. The water flow A2 for wall-adherence in all directions varies at each water inflow moment due to turbulence instability and will impact a main waterway A1 of the first water flow to deflect the main waterway when a flow rate for the wall-adherence is large. Therefore, a circumferentially oscillating pulsating water spray is generated, dynamic shaking water effect is achieved, water spray is fuller, discharging water is more uniform, and massaging feeling is remarkable. A second water inlet <NUM> is laterally disposed on an upper half of a side wall of the spherical chamber <NUM>, and an inner port of the second water inlet <NUM> is tangentially disposed to enable vortex water to be discharged. In addition, water spray from the water outlet hole <NUM> is controlled by flow rate variations of the first water inlet <NUM> and the second water inlet <NUM>. The two water dividing passages <NUM> are respectively in communication with the first water inlet <NUM> and the second water inlet <NUM>, and the control mechanism <NUM> is disposed between the water inlet passage <NUM> and the two water dividing passages <NUM> to steplessly adjust flow rate variations of the two water dividing passages <NUM>, so that flow rate variations of the first water inlet <NUM> and the second water inlet <NUM> can be steplessly adjusted.

With respect to a stepless adjustment of a water spray, referring to <FIG>, shaking spray water, shaking particle-shaped water and shaking column-shaped water are respectively discharged as follows. Referring to <FIG>, a large portion the water flows through the second water inlet <NUM> and a small portion flows through the first water inlet <NUM>. At this time, the shaking spray water is discharged. Referring to <FIG>, the water flows through the first water inlet <NUM> and the second water inlet <NUM> concurrently.

Referring to <FIG>, a large portion the water flows through the first water inlet <NUM> and a small portion flows through the second water inlet <NUM>. At this time, shaking shower water (i.e., the shaking column-shaped water) is discharged. The water outlet device discharges dynamic sprays, and a larger coverage (one nozzle corresponds to multiple points using shaking) can be achieved using fewer spray particles. When bathing needs are met, the water outlet nozzles can be appropriately reduced, so that a shower can be steplessly switched to an atomized water state (e.g., the shaking spray water state) and defines a larger spray angle under low pressure.

The water outlet device comprises a control chamber <NUM>, and the control chamber <NUM> is disposed between the water inlet passage <NUM> and the two water dividing passages <NUM>.

The driving mechanism <NUM> comprises a gear rack <NUM> configured to be slidably connected to a mounting body to be slidable, a push button <NUM> configured to be slidably connected to the mounting body to be slidable, and a first transmission gear <NUM>, a second transmission gear <NUM>, and a third transmission gear <NUM> configured to rotatably connected to the mounting body to be rotatable.

Therein, a sealing gasket does not need to be disposed between the two water dividing passages due to a stepless adjustment of the flow rate variations of the two water dividing passages, so that a switching force is mild and a current switching force is less than <NUM> N.
