[0002] People now have increasingly higher requirements for the functionality of water dispensing devices, and they are constantly improving and enhancing the water dispensing effect. Currently, the traditional sheet-like water spray patterns on the market are relatively simple and have a poor user experience, failing to meet people's demands for a high-quality life. At the same time, the current structure is prone to jamming, making the overall product experience poor. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a water outlet component.

[0004] This invention is achieved through the following technical solution:

A drive shaft is provided below the cycloidal wheel to drive the transmission component to rotate. The transmission component drives the water outlet component to rotate. The water outlet component is provided with a water outlet that can discharge sheet-like water.

[0006] In this embodiment of the invention, a pin is provided in the cavity, and the impeller, cycloidal wheel, and transmission component are all connected to the pin. The impeller and the transmission component are coaxially arranged. An internal gear is provided in the cavity, and the internal gear is engaged with the external teeth of the cycloidal wheel. A first gear is provided below the transmission component, and a second gear is provided on the outer periphery of the water outlet component and engaged with the first gear.

[0007] In this embodiment of the invention, the transmission component includes a main body and a first gear distributed vertically, a support rod distributed circumferentially around the main body, and an arc-shaped surface that can contact and cooperate with the drive shaft around the support rod.

[0008] In this embodiment of the invention, the arc-shaped surface is disposed in the middle of the support rod.

[0009] In this embodiment of the invention, the cycloidal wheel includes a disc, the external teeth are disposed on the outer periphery of the disc, and a drive shaft that mates with the arc-shaped surface is disposed below the disc.

[0010] In this embodiment of the invention, a perforation is provided in the center of the disc, and a cylinder is provided below the impeller. The cylinder is fitted into the perforation, and the perforation is eccentrically positioned relative to the impeller.

[0011] In this embodiment of the invention, a connecting ring disposed within the cavity is also included, and the internal gear is disposed on the inner peripheral wall at the lower end of the connecting ring.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] Referring to the accompanying drawings, a water outlet assembly includes a body 10, within which a cavity 11 is provided. The water inlet end 12 of the body is connected to the cavity. A drive structure and a water outlet component 50 are sequentially arranged within the cavity according to the water flow direction. The drive structure includes an impeller 20, a cycloidal wheel 30, and a transmission component 40. A pin 90 is also provided within the cavity, through which the impeller, cycloidal wheel, and transmission component are all connected. The impeller and transmission component are coaxially arranged, while the impeller and cycloidal wheel are eccentrically arranged. An internal gear 60 is provided within the cavity, engaging with the external teeth 31 of the cycloidal wheel. A drive shaft 32 is located below the cycloidal wheel, and the transmission component is configured to interact with the drive shaft. The invention features an arc-shaped surface 41 that mates with the shaft side; a first gear 42 is provided below the transmission component, and a second gear 51 that mates with and connects to the first gear is provided on the outer periphery of the water outlet component. In use, water flows into the cavity from the inlet end of the main body, driving the impeller to rotate. The impeller and the cycloidal wheel are eccentrically positioned. Simultaneously, under the cooperation of the internal gear and the external gear, the cycloidal wheel rotates eccentrically relative to the impeller. The rotation of the cycloidal wheel, under the cooperation of the drive shaft and the arc-shaped surface, also causes the transmission component to rotate. The transmission component and the impeller rotate coaxially. The rotation of the transmission component, under the cooperation of the first gear and the second gear, drives the water outlet component to rotate, thereby causing the water outlet component to rotate and discharge water. Preferably, the water outlet component can discharge sheet-like water.

[0029] Specifically, the transmission component 40 includes a main body 43 and a first gear 42 distributed vertically. A support rod 44 is distributed in a ring around the main body. An arc-shaped surface 41 that can contact and cooperate with the drive shaft is provided around the support rod. Since the cycloidal wheel, the internal gear and the water outlet form a planetary gear mechanism, the rotation of the cycloidal wheel is irregular. This will cause the contact point between the drive shaft and the transmission component to change. The cooperation between the arc-shaped surface and the drive shaft can prevent the overall structure from jamming when rotating, which is more conducive to transmission.

[0030] Preferably, the arc-shaped surface is located in the middle of the support rod, and the width of both ends of the support rod is greater than the width of the middle part. This can effectively ensure the stability of the fit between the drive shaft and the arc-shaped surface. Please refer to the attached drawings in the specification for details. Figure 4 .

[0031] Please refer to the attached diagram in the instruction manual for details. Figure 5 The cycloidal wheel 30 includes a disc 33, with external teeth 31 disposed on the outer circumference of the disc. A drive shaft 32, which mates with an arc-shaped surface, is disposed below the disc. In this embodiment, the transmission component has three support rods, each with an arc-shaped surface on both sides. Similarly, three drive shafts are disposed below the cycloidal wheel, each drive shaft engaging with the arc-shaped surface of one of the support rods, allowing for rotation of the impeller in any direction.

[0032] Furthermore, a through hole 34 is provided in the middle of the disc, and a cylinder 21 is provided below the impeller. The cylinder is installed in the through hole. The through hole is eccentrically set with respect to the impeller, and the cylinder is eccentrically set with respect to the pin shaft. This ensures that the planetary gear mechanism can transmit power normally.

[0033] More specifically, the present invention also includes a connecting ring 61 disposed within the cavity, with the internal gear disposed on the inner circumferential wall at the lower end of the connecting ring. An annular flange 62 is disposed below the internal gear on the connecting ring, with an opening 63 in the center of the annular flange. The cycloidal wheel is located above the annular flange, and the transmission component is located at the opening.

[0034] To better enable the impeller to rotate, an inclined water body 70 is also included in the cavity. The inclined water body is located at the front end of the impeller through which water passes. The inclined water body is provided with an inclined water passage hole 71. The water flowing out of the water passage hole can impact the impeller to rotate. Referring to the attached drawings of the specification, the water flows from top to bottom. When it passes through the inclined water body, the water flows out from the water passage hole and the lateral impact on the impeller drives it to rotate.

[0035] In a preferred embodiment of the present invention, the main body includes a cooperating upper body 13 and a lower body 14. A sealing ring 80 is provided between the upper body and the lower body. The lower body is provided with an opening 15 that cooperates with a water outlet. The water outlet is provided with a sheet-like water outlet 52. Preferably, a pin is provided between the inclined water body and the lower body to ensure the stability of the overall structure. A stepped surface 16 is provided on the inner periphery of the lower body, and the connecting ring is supported on the stepped surface.

[0036] More specifically, this invention involves water flow impacting an impeller, which rotates to drive a cycloidal wheel. The rotation of the cycloidal wheel then drives a transmission component, which in turn rotates the water outlet component. This achieves simultaneous rotation of the water outlet component and the dispensing of sheet-like water. Details are as follows:

[0037] 1. The water flow drives the impeller to rotate. The eccentrically mounted cylinder on the impeller rotates, which in turn drives the cycloidal wheel to rotate. The rotation of the cycloidal wheel drives the transmission component to rotate, which in turn drives the water outlet component to rotate and produce sheet-like water.

[0038] 2. The water-driven impeller rotates the cycloidal wheel, which in turn rotates the water outlet component to discharge water. This structure is relatively simple and easy to install and produce.

[0039] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
