The housing 200 is provided with a receiving cavity 230, and a first water inlet passage 221, a second water inlet passage 222, and a water outlet structure 300 all in communication with the receiving cavity 230, so that a first water flow can enter the receiving cavity 230 from the first water inlet passage 221 and then be discharged from the water outlet structure 300, and a second water flow can enter the receiving cavity 230 from the second water inlet passage 222 and then be discharged from the water outlet structure 300.

The second transmission member 500 is arranged in the receiving cavity 230, and comprises a second gear 510 engaged with the first gear 410, so that the first gear 410 can drive the second gear 510 to rotate when the first gear 410 rotates. The third transmission member 600 is arranged in the receiving cavity 230, and comprises a third gear 610 engaged with the second gear 510 and a second impeller 620 coaxially arranged with the third gear 610, the second impeller 620 being used to be driven by the second water flow from the second water inlet passage 222, so that the second water flow entering the receiving cavity 230 impacts second blades 621 of the second impeller 620 to drive the second impeller 620 to rotate, and the second impeller 620 rotates to drive the third gear 610 to rotate, and the third gear 610 drives the second gear 510 to rotate when the third gear 610 rotates. The first gear 410 and the third gear 610 jointly drive the second gear 510 to rotate, that is, the required force to drive the second gear 510 to rotate is shared by the first gear 410 and the third gear 610, so that the water pressure of the first water flow driving the first gear 410 to rotate can be smaller, and the water pressure of the second water flow driving the third gear 610 to rotate can be smaller, so as to facilitate the start of the water outlet device 100. The water flow control member 700 is arranged in the receiving cavity 230, and the third transmission member 600 is used to drive the water flow control member 700 to move relative to the water outlet structure 300, so that the water flow control member 700 controls the water flow rate and / or the water flow direction of the water outlet structure 300, so that the water outlet device 100 can realize the dynamic water outlet function.

[0048] It should be noted that the first direction mentioned herein is the C direction in the drawings, and the second direction is the D direction in the drawings.

[0049] Optionally, in one embodiment and another embodiment, the number of teeth of the second gear 510 is greater than the number of teeth of the first gear 410 and greater than the number of teeth of the third gear 610. In this way, the first transmission member 400 and the third transmission member 600 can achieve the effect of speed reduction and torque increase for the second transmission member 500, which is beneficial to further reduce the water pressure driving the water outlet device 100.

[0050] Optionally, in one and another embodiment, the first gear 410 and the second gear 510 are respectively disposed on both sides of the second transmission member 500 in a radial direction of the second gear 510. This facilitates the uniform force on the second gear 510, thereby reducing the degree of damage to the second gear 510 and improving the service life of the water outlet device 100. However, this design is not limited to this. In other embodiments, on a first plane perpendicular to the rotation axis of the second gear 510, the projection centers of the first gear 410, the second gear 510, and the third gear 610 are not on the same straight line. It is worth mentioning that in one embodiment, the structure of the first transmission member 400 and the structure of the second transmission member 500 are usually set to be the same to make the second gear 510 uniformly stressed. Of course, the first transmission member 400 and the second transmission member 500 are allowed to differ, as long as the force received by the second gear 510 is as uniform as possible.

[0051] There are many specific forms for the water flow control component 700 and the water outlet structure 300, which can be referred to together. Figure 5 and 6 Optionally, in one embodiment, the water outlet structure 300 includes a first water outlet 310, and the water flow control component 700 includes a water flow control part 710, which passes through the first water outlet 310. A water outlet gap exists between the outer peripheral surface of the water flow control part 710 and the first water outlet 310 in a first direction. The second transmission component 500 drives the water flow control part 710 to reciprocate along the first direction to control the water flow direction of the first water outlet 310. Thus, during the reciprocating movement of the water flow control part 710 along the first direction, the shape of the water outlet gap can be changed, thereby changing the water flow direction.

[0052] Refer to together Figure 7Optionally, in an embodiment, in the first direction, the water flow control part 710 has opposite first and second side walls 711 and 712, the first side wall 711 is arranged to be inclined towards the second side wall 712 in the water outlet direction of the first water outlet hole 310, the second side wall 712 is arranged to be inclined towards the first side wall 711 in the water outlet direction of the first water outlet hole 310, the water outlet hole has a third side wall 312 cooperating with the first side wall 711 and a fourth side wall 313 cooperating with the second side wall 712. In this way, the water outlet device 100 has a first state, a second state and a third state, when the water flow control part 710 reciprocates in the first direction, the water outlet device 100 can switch between the first state, the second state and the third state, when the water outlet device 100 is in the first state, the first side wall 711 abuts against the third side wall 312, the second side wall 712 has a water outlet gap with the fourth side wall 313, the flow direction of the water flow is the inclined direction of the second side wall 712, when the water outlet device 100 is in the second state, the second side wall 712 abuts against the third side wall 312, the first side wall 711 has a water outlet gap with the third side wall 312, the flow direction of the water flow is the inclined direction of the first side wall 711, when the water outlet device 100 is in the third state, the first side wall 711 and the third side wall 312 have a gap therebetween, and the second side wall 712 and the fourth side wall 313 have a gap therebetween, part of the water outlet gap is located between the first side wall 711 and the third side wall 312, and part of the water outlet gap is located between the second side wall 712 and the fourth side wall 313, part of the water flow has the flow direction of the inclined direction of the first side wall 711, and part of the water flow has the flow direction of the inclined direction of the second side wall 712. It can be understood that, since the inclined directions of the first and second side walls 711 and 712 are different, when the water flow control part 710 reciprocates in the first direction, the water flow directions of the water outlet structure 300 in the first state, the second state and the third state of the water outlet device 100 are different. Of course, in other embodiments, the first and second side walls 711 and 712 can also be arranged to be inclined in other directions, as long as the inclined directions of the first and second side walls 711 and 712 are different.

[0057] Specifically, the blocking surface 713 can continue to move after completely blocking the second water outlet hole 331 to gradually expose the second water outlet hole 331, gradually block the third water outlet hole 332 after completely exposing the second water outlet hole 331, continue to move after completely blocking the third water outlet hole 332 to gradually expose the third water outlet hole 332, and gradually block the second water outlet hole 331 after completely exposing the third water outlet hole 332. Alternatively, the blocking surface 713 can continue to move after blocking the second water outlet hole 331 to gradually expose the second water outlet hole 331 and gradually block the third water outlet hole 332. During the movement, the area of the second water outlet hole 331 exposed per unit time is not equal to the area of the third water outlet hole 332 blocked per unit time until the third water outlet hole 332 is completely blocked. The blocking surface 713 continues to move after completely blocking the third water outlet hole 332 to gradually expose the third water outlet hole 332 and gradually block the second water outlet hole 331. During the movement, the area of the third water outlet hole 332 exposed per unit time is not equal to the area of the second water outlet hole 331 blocked per unit time until the second water outlet hole 331 is completely blocked. Of course, there are other ways to make the water flow control member 700 control the water outlet amount of the water outlet hole, which will not be described in detail here.

[0058] Optionally, in yet another embodiment, the water outlet direction of the second water outlet hole 331 is different from the water outlet direction of the third water outlet hole 332. In this way, the water flow direction of the water outlet structure 300 when the blocking surface 713 blocks the second water outlet hole 331 is different from the water flow direction of the water outlet structure 300 when the blocking surface 713 blocks the third water outlet hole 332, so that the water outlet device 100 can realize dynamic water outlet.
