Further, the transmission assembly 4 further comprises a plurality of transmission gears 45 arranged between the gear fixing plate 41 and the gear cover 43 and in transmission connection between the gear shaft 42 and the output gear 44. By providing different numbers of the transmission gears 45 and different gears of the transmission gears 45, the transmission ratio between the gear shaft 42 and the output gear 44 can be changed, thereby achieving a decelerated transmission and increasing a torque force output by the transmission assembly 4.

At the same time, the protrusion 21 is a block-shaped part independently mounted on an upper surface of the water outlet assembly 2, that is, the protrusion 21 is detachably connected to the water outlet assembly 2, and the protrusion 21 with different stadium-shaped holes 211 can be replaced according to the design requirements of the product to control and adjust the swinging angle.

The control assembly 5 can control whether the rotation stopping pin 53 limits the rotation of the impeller 3 through the action of a user pressing the button 52, thereby controlling the swinging of the water outlet assembly 2, thus providing the user with flexible choices and a better product experience. In this embodiment, as the gear fixing plate 41 is arranged to seal the side opening 111 of the water flow-through cavity 11, the button fixing seat 51 is mounted on the gear fixing plate 41, and the rotation stopping pin 53 is movably and sealingly arranged on the gear fixing plate 41 in a penetrating manner.

In some embodiments of the control assembly 5, an upper surface of the rotation stopping protrusion 31 is an inclined surface 311, and the inclined surface 311 is inclined towards the end surface of the impeller 3 along a circumferential direction of the impeller 3. By providing the inclined surface 311, when the user presses the button 52 to push the rotation stopping pin 53 to abut against the inclined surface 311, the impeller 3 can still continue to rotate until the rotation stopping pin 53 abuts against the side surface of the rotation stopping protrusion 31.

In some embodiments of the control assembly 5, an inner wall of the moving channel 511 is repeatedly provided with a plurality of sets of structures, with each set of structures comprising a long groove 512, a short groove 513 and a first unidirectional tooth 514; a circumferential surface of the button 52 is provided with guiding protrusions 521 which are slidably engaged in the long grooves 512, such that the button 52 can axially move in the moving channel 511 without rotating, and an end surface of the button 52 facing the rotation stopping pin 53 is provided with a plurality of bidirectional teeth 522; a circumferential surface of the rotation stopping pin 53 is provided with limiting protrusions 531 which are slidably engaged in the long grooves 512 or the short grooves 513, and an end surface of the rotation stopping pin 53 facing the button 52 is provided with a plurality of second unidirectional teeth 532 which are arranged at equal angular intervals. The click-pen mechanism 5a is formed by the long grooves 512, the short grooves 513, the first unidirectional teeth 514, the guiding protrusions 521, the bidirectional teeth 522, the limiting protrusions 531 and the second unidirectional teeth 532, which is a typical retractable ball-point pen mechanism. Each time the button 52 is pressed, the rotation stopping pin 53 is driven to rotate by the bidirectional teeth 522 abutting against the second unidirectional teeth 532, and after rotating, the limiting protrusion 531 of the rotation stopping pin 53 is guided by the first unidirectional teeth 514 to be engaged in either the long grooves 512 or the short grooves 513, as the long grooves 512 and the short grooves 513 have different depths, the axial position of the rotation stopping pin 53 in the moving channel 511 is changed. In this embodiment, the rotation stopping pin 53 is composed of a pin shaft 53a and a movable part 53b, which are designed separately; the limiting protrusions 531 and the second unidirectional teeth 532 are both arranged on the movable part 53b, a limiting plate 533 is arranged on an end portion of the pin shaft 53a opposite to the movable member 53b, and the movable part 53b and the reset spring 54 are located on two sides of the limiting plate 533, respectively. As the movable part 53b is designed separately from the pin shaft 53a, a rotation torque force generated when the rotation stopping pin 53 is driven is not transmitted to the pin shaft 53a, such that the rotation of the movable part 53b is smoother. In other embodiments, the rotation stopping pin 53 may be an integral part.

In some embodiments of the control assembly 5, a circular gasket 55 is arranged on an inner end of the moving channel 511, and the rotation stopping pin 53 penetrates through the circular gasket 55 into the water flow-through cavity 11.

The water outlet pipe 13 is used as a water path communicating part and a rotating shaft of the water outlet assembly 2, and has multiple functions, such that the product has a simpler and more compact structure and is small in size.

The present invention further comprises a ball joint 6 mounted at a water inlet end of the water flow-through part 1, such that the product of the present invention not only can automatically swing the water outlet assembly 2 when water enters, but also can more flexibly adjust an initial orientation of the water outlet assembly 2 according to the user requirements.
