[0018] Compared with the background technology, this technical solution has the following advantages:

[0019] The water outlet component is provided with a spherical cavity. The bottom of the spherical cavity is provided with a water outlet hole, the top is provided with a first water inlet, and the side wall is provided with a second water inlet. First, the first water flow entering the spherical cavity from the first water inlet, under the action of Bernoulli, increases its kinetic energy and flow velocity. Due to the wall-attached effect of the water flow, a small part of the water flow will attach to the cavity wall when it rushes into the spherical cavity. And due to the instability of turbulence, the size of the wall-attached water flow in each direction is different at each water inlet moment. The wall-attached water flow with a large flow rate will impact the main water path of the first water flow, causing the main water path to deflect, thereby generating circumferential oscillating pulsating water flowers, achieving a dynamic dithering water effect, making the water flowers more plump, the water outlet more uniform, and the massage feeling more significant. Second, it realizes full-coverage water outlet. Third, by controlling the flow rate change of the first water inlet and the second water inlet to control the water flowers flowing out of the water outlet hole, stepless change of the water flowers at the same water outlet hole can be achieved.

[0020] When the first water inlet enters the spherical cavity, the cross-sectional area changes greatly, and the Bernoulli effect is good.

By pressing the push button, the rack is driven to move, the gear is driven to rotate, and the valve core is driven to rotate through the speed reduction mechanism, driving the valve core to rotate back and forth synchronously, so that the flow rates of the two water inlets change, and stepless change of the water flowers at the same water outlet hole is realized.

[0022] The second water inlet is arranged in the upper half of the side wall of the spherical cavity and is horizontally arranged, so as to generate eddy rotating water when entering the spherical cavity.

[0023] The inner cavity wall of the control cavity has an arc surface. The two water diversion ports are located on the arc surface and are circumferentially spaced.

[0039] Please refer to Figures 1 to 8, The water outlet device includes a water outlet component 11, a control mechanism 12, a water inlet path 13, and two branch water paths 14. The water outlet component 11 is provided with a spherical cavity 111; at the exact center of the bottom of the spherical cavity 111, there is a water outlet hole 112, and at the exact center of the top, there is a first water inlet 113. The first water inlet 113 and the water outlet hole 112 are arranged opposite to each other. When the first water inlet 113 enters the spherical cavity 111, the cross-sectional area changes suddenly and becomes larger, and the cross-section of the first water inlet 113 gradually increases from top to bottom. The first water flow entering the spherical cavity 111 from the first water inlet 113, under the action of Bernoulli, increases its kinetic energy and flow velocity. Due to the wall-attaching effect of the water flow, a small part of the water flow A2 will attach to the cavity wall when it rushes into the spherical cavity 111. And due to the instability of turbulence, the size of the wall-attaching water flow A2 in each direction is different at each water inlet moment. The wall-attaching water flow with a large flow rate will impact the main water path A1 of the first water flow, causing the main water path to deflect, thereby generating circumferential oscillating pulsating water flowers, achieving a dynamic jittering water effect, making the water flowers more plump, the water outlet more uniform, and the massage feeling more significant; on the upper half of the side wall of the spherical cavity 111, there is a second water inlet 114 arranged horizontally, and the inner port of the second water inlet 114 is tangentially arranged to enable swirling water outlet. Moreover, the water outlet water flowers of the water outlet hole 112 are controlled by the flow rate changes of the first water inlet 113 and the second water inlet 114. The two branch water paths 14 are respectively connected to the first water inlet 113 and the second water inlet 114, and the control mechanism 12 is arranged between the water inlet path 13 and the two branch water paths 14 to be able to steplessly adjust the flow rate changes of the two branch water paths 14, so as to be able to steplessly adjust the flow rate changes of the first water inlet 113 and the second water inlet 114.

[0040] Regarding the stepless adjustment of water flowers, such as Figure 4 , Figure 5 and Figure 6 respectively produce jittering spray water, jittering granular water, and jittering columnar water. Specifically: as Figure 4 , most of the water path goes through the second water inlet 114, and a small part goes through the first water inlet 113. At this time, jittering spray water is produced; as Figure 5 , both the first water inlet 113 and the second water inlet 114 are passed through simultaneously. At this time, jittering fine granular water (the water outlet state has a small lantern) is produced; as Figure 6 , most of the water path goes through the first water inlet 113, and a small part goes through the second water inlet 114. At this time, jittering sprinkler water is produced. The water outlet device produces dynamic water flowers with fewer water particles, which can achieve a larger coverage range (jittering realizes multiple points from one nozzle). Under the condition of meeting the bathing needs, the number of water outlet nozzles can be appropriately reduced, so that the shower head can be steplessly switched to the atomized water state, and a larger water flower opening angle can be presented under low pressure.

[0041] The water outlet device is provided with a control chamber 15, which is arranged between the water inlet path 13 and the two branch water paths 14. The inner cavity wall of the control chamber 15 has an arc surface, and both of the two branch water paths 14 have water diversion openings 141 located on the arc surface; the control mechanism 12 includes a valve core 121 and a driving mechanism 122. The valve core 121 further includes a valve plate 1211, a turntable mechanism 1212 and a driving shaft 1213. The valve plate 1211 is in an arc shape, the valve plate 1211 is fixedly connected to the side of the turntable mechanism 1212, the driving shaft 1213 is fixedly connected to the axis position of the turntable mechanism 1212, the turntable mechanism 1212 is rotatably connected in the control chamber 15, the valve plate 1211 is adapted to be closely attached to the arc surface of the inner cavity wall, and the blocked area of the two water diversion openings 141 is controlled steplessly by the valve plate 1211 to steplessly adjust the flow rate change of the two branch water paths 14. The driving mechanism 122 includes a rack 1221 that can be slidably connected to the installation main body to be slidable, a push button 1222 that can be slidably connected to the installation main body to be slidable, a first transmission gear 1223 that can be rotatably connected to the installation main body, a second transmission gear 1224 and a third transmission gear 1225. The push button and the rack are fixedly connected together. The first transmission gear meshes with the rack. The first transmission gear and the second transmission gear are coaxially fixedly connected. The second transmission gear and the third transmission gear mesh. The driving shaft 1213 and the third transmission gear are coaxially fixedly connected. Deceleration is achieved through the cooperation of the second transmission gear 1224 and the third transmission gear 1225. The third transmission gear constitutes a runner that drives the driving shaft to rotate. Among them: Due to the stepless adjustment of the flow rate change of the two branch water paths, there is no need to set a gasket between the two branch water paths, so the switching force is light. Currently, the switching force is less than 2N.

[0042] The water outlet device further includes a fixed seat component 16; the water outlet component 1 includes a face cover 17 and a water distribution body 18.

A second water distribution cavity 142 communicating with the second water inlet is formed between the water distribution body and the face cover; the fixed seat component 16 is fixedly arranged on the water distribution body 18, and a first water distribution cavity 143 communicating with the first water inlet is formed between the fixed seat component and the water distribution body; the fixed seat component 16 includes a fixed seat 162 with a parallel water tank 161 recessed on the top surface and a sealing cover 163 hermetically connected above the fixed seat 162 to cover the notch of the water tank 161. The two water tanks 161 are respectively communicated with the first water distribution cavity 143 and the second water distribution cavity 142 through through holes, and the water distribution paths respectively include the above-mentioned water tank 161 and the water distribution cavity. The water inlet path, a part of the water distribution paths and the control mechanism are all arranged on the fixed seat component. In a specific structure: the water distribution body 18 protrudes downwardly with a convex seat 182, the convex seat 182 is recessed to form the above-mentioned upper cavity 181, and a ring convex 183 is protruded on the outer circumference of the convex seat 182; the face cover 17 is recessed to form the above-mentioned lower cavity 171 and also recessed with a ring groove 172 surrounding each lower cavity 171, and the ring convex and the ring groove are adaptively inserted.
