[0039] See also Figures 1 to 8 The water outlet device, in this specific embodiment, includes a water outlet portion 10 and a rear cover 20, the water outlet portion 10 is a water outlet surface cover. The water outlet portion 10 and the rear cover 20 are arranged in a front and back direction and are sealed and fixedly assembled together, such as with a sealing ring 21 to achieve sealing, and a water outlet cavity 22 is formed between the rear cover and the water outlet portion, and the water outlet cavity 22 can be connected to the water outlet nozzle.

[0040] The water outlet 10 is provided with N water outlets, N is a natural number greater than 3, there are at least M water outlets among the N water outlets, M is a natural number not greater than N and greater than 2, each of the M water outlets is equipped with a movable component 30, the movable component 30 includes a driving part 31 and a movable part 32, the movable part 32 at least partially extends into the water outlet sleeve 12, the driving part 31 is rotated relative to the water outlet 10 by the impact of the water flow flowing to the water outlet, the driving part 31 is connected to the movable part 32, and the movable part 32 is driven to make a circular motion around the rotation axis of the driving part 31 through the rotation of the driving part 31.

[0041] In the specific structure: the water outlet 10 is provided with a mounting hole 11 that runs through the front and back sides, and the M water outlet nozzles are all provided with a water outlet nozzle sleeve 12, the water outlet nozzle sleeve 12 is fixed in the mounting hole 11 and the inner hole of the water outlet nozzle sleeve 12 constitutes the water outlet nozzle, the mounting hole 11 is a stepped through hole that is small in the front direction and large in the back direction, the outer wall of the water outlet nozzle sleeve 12 is adapted to be assembled in the stepped through hole, and a rotation limiting mechanism is provided between the stepped through hole and the water outlet nozzle sleeve 12. The water outlet nozzle sleeve 12 has a protruding portion that protrudes from the back side of the water outlet 10. The water outlet nozzle sleeve 12 is provided with a matching seat 13, and the matching seat 13 is provided with an outer peripheral wall 132, which is adapted to be fitted outside the protruding portion of the water outlet nozzle sleeve 12 to seal and fix the matching seat 13 and the water outlet nozzle sleeve 12 together.

[0042] The driving part 31 includes an impeller 311 and an eccentric shaft 312 coaxially fixed under the impeller 311. The eccentric shaft 312 is a cam structure. The driving part 31 is also provided with a central hole 313 that runs through the upper and lower parts. The matching seat 13 is also fixed with a central shaft 131 that extends downward. The central shaft 131 is adapted to penetrate into the central hole 313 so that the driving part 31 can rotate relative to the central shaft 131. The driving part 31 is positioned by the central shaft 131. Other positioning methods can also be used as needed, such as the driving part is provided with a central shaft, and the central shaft is rotatably connected to the matching seat, etc. The water outlet sleeve 12 is provided with a water inlet hole 122 that runs through the inside and outside of the water outlet sleeve 12. The water inlet hole 122 is at least partially located in the protruding part. The water flow that flows into the water outlet sleeve 12 from the water outlet cavity through the water inlet hole 122 impacts the impeller 311 to drive the driving part 31 to rotate.

[0043] The nozzle sleeve 12 includes a rotating hole section 121, the rotating axis of the rotating hole section 121 coincides with the rotating axis of the driving part 31, and the axis of the impeller 311 coincides with the rotating axis of the driving part 31. The movable member 32 includes a connecting seat 321 and a needle body 322 fixedly connected below the connecting seat 321. The top surface of the connecting seat 321 is concavely provided with an assembly hole 323, and the needle body 322 is eccentrically arranged relative to the axis of the impeller 311. The eccentric shaft 312 is adapted to be assembled in the assembly hole 323, so that the eccentric movement of the eccentric shaft 312 drives the movable member 32 to make a circular motion around the axis of the rotating hole section 121, and drives the needle body 322 to make a circular motion around the axis of the rotating hole section 121.

[0044] One of the inventive points of the present invention is that a speed reduction mechanism 33 is provided between the movable part 32 and the water outlet. The speed reduction mechanism 33, for example, includes an outer gear 331 provided outside the movable part 32, for example, arranged circumferentially on the outer peripheral wall of the connecting seat 321; and, the inner wall of the water outlet is provided with an inner gear 332, for example, arranged circumferentially on the inner peripheral wall of the water outlet sleeve 12; the outer gear is meshed with the inner gear, and the number of outer gear teeth outside the movable part 32 and the number of inner gear teeth of the water outlet are set in a difference to form a differential gear motion mechanism to achieve speed reduction, so that the self-rotation speed of the needle body 322 is slower than the rotation speed of the impeller, the frequency of the massage water splashes formed is smaller, and the massage effect and visual effect are better. Other speed reduction mechanisms can also be used as needed, such as through a gear combination.

[0045] In this specific embodiment: the needle body 322 is in contact with the hole wall of the rotating hole section 121 of the water outlet sleeve 12, and the needle body 322 can scrape off the scale attached to the hole wall to achieve a cleaning effect when the needle body 322 moves in a circular motion around the rotation axis of the driving part 31. At the same time, since the water flow will generate a high-speed rotating vortex when it hits the impeller 311, the vortex is stirred (interfering with the water splash) in the water outlet sleeve 12 by the needle body 322 (the needle body rotates at a speed lower than the impeller), and the vortex and stirring cooperate to produce water splashes with a massage effect. Therefore, in this specific implementation scheme, the following technical effects can be produced through the cooperation of the impeller, the needle body and the water outlet: First, it can scrape off the scale attached to the hole wall to achieve a cleaning effect, prevent the water splash from obliquely shooting and blocking the hole, and has a self-cleaning function; second, the vortex and agitation are combined to produce a shaking water splash with a massage effect; third, each water outlet is equipped with a rotating component, which can reduce the production accuracy of the water outlet and the rotating component. The rotating component can achieve standardized production and can be equipped with water outlet devices with different numbers of water outlets or different arrangements of water outlets, reducing manufacturing costs; fourth, the frequency of the massage water splash formed is relatively small, and the massage effect and visual effect are better. The above-mentioned water outlet, movable component and matching seat cooperate to form a water outlet unit.

[0046] In the specific structure: the rear cover 20 extends backward with a connecting ring wall 23, and the connecting ring wall 23 is equipped with a nut 24, a bushing 25 and a ball head 26. The rear cover 20 can be detachably mounted on the water supply source through the nut 24, the bushing 25 and the ball head 26. The technology can refer to the existing technology. A second sealing ring 231 is arranged between the ball head 26 and the connecting ring wall 23 of the rear cover 20. A filter screen gasket 232 and a water-saving sheet 233 can also be arranged in the ball head 26. The matching seat 13 is pressed by the rear cover 20, and the water outlet, the rear cover and the matching seat are assembled together by pressing. According to needs, the screw 333 is provided with a gasket 334.

[0047] In this specific embodiment, N and M are equal, that is, all the nozzle covers 12 are provided with movable parts 30. However, this is not limited to the above. Since the nozzle covers 12 are equipped with independent movable parts 30, some nozzle covers 12 may not have the movable parts 30, so that the water outlet device can produce different water splashes, and can be flexibly grafted into any multifunctional shower as a functional component to increase its functional diversity and improve the shower experience. Moreover, since the nozzle covers 12 are equipped with independent movable parts 30, the water outlet 10 and the rear cover 20 can be connected not only by fixed connection, but also by rotation connection.

[0048] The water outlet unit of this specific embodiment does not have high requirements on the shape of the cavity and the layout of the water outlets. Unlike conventional showers, the same type of water spray needs to be arranged in a regular ring or concentrated in the center. The water outlets can be arranged in any shape, such as a triangle, S shape, Y shape, etc., or in partitions, not in the same cavity, arranged in a triangle on the left, and in a square on the right, etc. For example Fig. 9 The six water outlets are arranged at intervals around the circumference, or as Fig.10 In the embodiment, the seven water outlets are arranged at intervals other than the circumference. Fig.11 In the embodiment, seven water outlets are arranged in a Y-shaped arrangement, or in an S-shaped arrangement, etc.

[0049] Of course, as required, the movable member 32 and the hole wall of the water outlet sleeve 12 can be arranged apart. In this case, the water outlet device does not play a cleaning role, but can make the water outlet emit water with a massage effect.

[0050] The above are only specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
