Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a swing water outlet device and a faucet. Background Technology

[0002] In daily life, faucets are essential water-using devices in homes and public places, and their efficiency and user experience directly impact water resource utilization and cleaning effectiveness. However, most faucets on the market currently suffer from concentrated water flow or near-static water spray. This water flow pattern results in low efficiency for cleaning kitchen and bathroom dishes, low water utilization, and significant waste. Furthermore, the water spray patterns of existing faucets generally lack significant differentiation, making it difficult for these products to leave a lasting impression on users in both advertising and actual experience, resulting in low brand recognition and failing to meet consumers' demands for personalized and efficient cleaning.

[0003] Meanwhile, existing faucet designs typically rely on fixed spout structures, resulting in a relatively uniform water spray pattern after the water flows through the spout. This fails to achieve dynamic or large-area cleaning effects and can only be achieved through manual operation. Although some high-end faucets attempt to improve the water spray pattern by increasing aeration or changing the spout shape, these improvements are often limited to static water spray variations and still fail to address the issues of low cleaning efficiency and water waste. Furthermore, this type of design has poor adaptability under different water pressure conditions, potentially leading to unstable water flow due to pressure fluctuations, further impacting the user experience. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, 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", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] 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 utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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.

"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.

[0035] Referring to the accompanying drawings, this utility model relates to a swing water outlet device and a faucet containing the device. Its core is to achieve large-area cleaning and highly recognizable swing water outlet effect under high and low water pressure conditions through an internally integrated hydraulically driven swing mechanism. The swing water outlet device is manufactured as a module and can be configured in the installation cavity, or it can be replaced with other modules (such as an aerator) placed in the installation cavity for use.

[0036] In practical applications, the oscillating water outlet device of this utility model includes a housing 1, one end of which is equipped with a jet port 2 for water flow. The housing 1 contains a cavity for housing the hydraulic drive device 3 and the oscillating mechanism 4. The core component of the oscillating mechanism 4 is an oscillating element 5, which has a water outlet 6 connected to the jet port 2. When water enters the housing 1 from the jet port 2, it is first processed by the hydraulic drive device 3, then transmitted to the oscillating mechanism 4, and finally sprayed out by the water outlet 6. During this process, the cooperation between the hydraulic drive device 3 and the oscillating mechanism 4 ensures that the water outlet 6 can achieve reciprocating oscillation, thus creating the oscillating water outlet effect. The specific operating principle and process are described below.

[0037] The hydraulic drive device 3 includes an output wheel 7 and a central shaft 16. The output wheel 7 is equipped with a linkage part, which is connected to the swing mechanism. The output wheel 7 can move around a first axis in a circle under the direct or indirect drive of water flow. The first axis is the axis of rotation of the output wheel and can be in the same direction as the axis of the central shaft. In one use, the linkage part can be the output shaft below the output wheel. The output shaft is eccentrically set with the axis of the output shaft. The size of the axis distance can be used to adjust the swing amplitude of the swing member. The linkage part of the output wheel can link the swing member to swing back and forth within a preset swing angle range so that the water sprayed from the water outlet has a reciprocating swing pattern.

[0038] When water flows in from the jet inlet 2, it directly impacts the impeller 17, causing it to rotate. The upper end of the impeller 17 is concentrically mounted on the central shaft 16, while its lower end is designed as a radially offset eccentric shaft structure, also known as a cam 20, which can be inserted. The rotation of the impeller 17 drives the planetary gear 18 to rotate. The upper end of the planetary gear 18 is an external gear structure, which meshes with the internal gear 19 on the inner wall of the housing 1, forming a reduction transmission relationship based on the principle of gear transmission with a small tooth difference. Since the number of external teeth of the planetary gear 18 is less than the number of teeth of the internal gear 19, the rotational speed of the planetary gear 18 is significantly lower than the rotational speed of the impeller 17. The lower end of the planetary gear 18 is provided with a protrusion 22, which inserts into the recess 21 on the output wheel 7 and cooperates with the side wall of the recess 21, thereby converting the rotation of the planetary gear 18 into the uniform circular motion of the output wheel 7. The recess can be composed of multiple ribs or multiple round holes. The rotation of the output wheel 7 is transmitted to the oscillating mechanism 4 through the linkage 8, ultimately completing the power transmission. Specifically: the outer tooth structure of the planetary gear can mesh with the inner tooth structure of the internal gear, and the number of outer teeth is less than the number of inner teeth; the rotation of the impeller is transmitted to the planetary gear through the eccentric cam and drives it to revolve relative to the central axis; the meshing of the inner and outer teeth of the planetary gear and the housing forms a counter-rotation based on a certain tooth difference, thereby constituting a speed reduction transmission; the concave and convex structures on the output wheel and the planetary gear can form a mating connection so that when the planetary gear rotates, it drives the output wheel to rotate; the axis of the linkage is eccentrically set with respect to the central axis. The output wheel can be configured at the opening above the bushing, and the length direction of the slide groove is perpendicular to the axial direction of the linkage.

[0039] The swinging component, the output wheel, and the housing are adapted to be provided with a swing limiting structure for determining a preset swing angle; wherein, the swing limiting structure mainly consists of two parts: 1. the cooperation between the linkage part and the slide groove, 2. the swing limiting structure of the swinging component; the swing limiting structure of the swinging component can also have two embodiments, one of which is the shaft hole method, and the other is the plane to plane limiting method, which will be described in detail below.

[0040] Refer to the attached diagram in the instruction manual. Figure 5 , Figure 6The shaft hole configuration can be as follows: The core component of the swing mechanism 4 is a swing element 5, which is disposed in a bushing 9 fixed inside the housing 1. A pair of connecting shafts 10 are provided on the outer periphery of the swing element 5. A shaft hole 11 is provided on the peripheral wall of the bushing 9 to mate with the connecting shafts 10. The mating of the connecting shafts and the shaft hole allows them to rotate relative to each other, enabling the swing element 5 to swing within the bushing 9, thus achieving a hinge connection between the swing element and the housing. A sliding groove 12 is provided at the top of the swing element 5. A linkage part 8 is inserted into and engages with the sliding groove 12. When the linkage part moves circumferentially with the output wheel, it slides within the sliding groove and links the swing element to reciprocate around the hinge point with the housing. The swing element is sealed to the housing on the outer periphery of the water outlet. Specifically, the lower outer periphery of the swing element 5 is designed as a spherical structure 15, which engages with a sealing element 14 to achieve a dynamic seal during the swinging process. The sealing element 14 is fixed inside the housing 1 by the bottom of the bushing 9 and the housing 1, ensuring the integrity of the water spray while preventing water leakage. In other words, the swinging element and the housing are sealed together by the sealing element.

[0041] Refer to the attached diagram in the instruction manual. Figure 7 , Figure 8 The plane-to-plane restriction method can be: the configuration of the linkage part and the slide groove is similar to that of the shaft hole, and the swing member is provided with a limiting part 37; when the linkage part 8 moves in the circumference with the output wheel 7, the linkage part 8 slides in the slide groove 12 and links the swing member to swing back and forth relative to the first axis. During the swing of the swing member, the limiting part 37 abuts against the inner wall of the bushing or the limiting part 38. Through the relationship between the two planes of the limiting part 37 and the limiting part 38, the swing member can only swing back and forth along the plane.

[0042] To further illustrate the practical application scenario of this utility model, a specific usage process is described below. S1: The user turns on the faucet, and the water flows into the body 28 through the pull-out inlet 29. S2: Pressing the button 35 controls the switching device 36 (similar to the prior art, not described in detail here), and the water flow switches to one of the outlet channels 30, flowing into the mounting cavity and connecting to the jet port 2. S3: The water flows from the jet port 2 into the jet component 23, directly or indirectly impacting the impeller 17 to make it rotate. S4: The rotation of the impeller 17 drives the planetary gear 18 to rotate through the eccentric shaft structure. The external gear of the planetary gear 18 meshes with the internal gear 19 on the inner wall of the jet component 23, forming a speed reduction transmission. S5: The protrusion 22 of the planetary gear 18 inserts into the recess 21 of the output wheel 7, converting the rotation of the planetary gear 18 into the uniform circular motion of the output wheel 7. S6: The rotation of the output wheel 7 is transmitted to the sliding groove 12 of the oscillating component 5 through the linkage part 8, causing the oscillating component 5 to oscillate back and forth within the bushing 9. S7: The water outlet 6 of the swing member 5 swings with the oscillation motion of the swing member 5, ultimately forming a sheet-like water splash with high recognizability and dynamic oscillation. This water splash is guided by the flow channel features, elliptical surface structure and umbrella-shaped water outlet structure inside the swing member 5, ensuring uniform water flow and wide coverage; in one embodiment, the water outlet is configured to discharge sheet-like water.

[0043] In terms of structural design, the housing 1 is formed by the interlocking of a jetting element 23 and a fixed sleeve 24. The water outlet 13 can be located below the fixed sleeve, and a sealing ring 25 is provided between the two to ensure sealing. A stepped surface 27 is provided on the inner circumference below the jetting element 23, and a flange 26 is provided on the outer circumference above the bushing 9. The flange 26 abuts against the upper end face of the fixed sleeve 24, and the upper end of the flange 26 abuts against the stepped surface 27, thereby fixing the bushing 9 inside the housing 1. In addition, an installation cavity 31 is provided inside the body 28, and the housing 1 is fixed in the installation cavity 31 by the second thread 33 on its outer circumference engaging with the first thread 32 on the inner circumference of the installation cavity 31. A sealing gasket 34 is also provided between the housing 1 and the installation cavity 31 to further enhance the sealing performance. At the same time, a water outlet element of similar size to the housing can be replaced with this swinging water outlet device to achieve modular production and realize the water outlet effect of the pull-out head as needed.

[0044] The advantages of this invention lie in its modularly designed oscillating water outlet device, which facilitates disassembly and replacement. The water flow into the housing from the jet inlet drives the impeller to rotate, resulting in a stable oscillating water outlet effect, significantly improving cleaning efficiency and cleaning area. Furthermore, the sheet-like water spray formed by the oscillating water outlet is highly recognizable, significantly enhancing the product's market competitiveness. In practical use, users can flexibly switch between normal water outlet mode and oscillating water outlet mode via button 35 to meet the needs of different scenarios.

[0045] In summary, this utility model, through its ingenious structural design and efficient transmission mechanism, successfully solves the problems of concentrated water outlet points, low cleaning efficiency, low water utilization rate, and insufficient product recognition in existing technologies, and provides a highly functional and user-friendly swing-out water device and faucet.

[0046] By integrating a modularly designed hydraulically driven oscillating mechanism, the faucet only requires a single mounting cavity that conforms to the structure of the oscillating mechanism to achieve a large-area cleaning oscillating water flow effect, significantly improving product functionality and user experience. Specifically, water enters through the inlet of the pull-out head. Pressing a button switches the water flow from the inlet to the outlet, connecting to the jet nozzle. Water then enters the jet component through the jet nozzle, which has a central shaft. The lower inner wall of the jet component forms an internal gear structure. The jet drives the impeller to rotate. The upper end of the impeller is concentrically mounted on the central shaft, while the lower end is a radially offset eccentric shaft structure. Planetary gears are assembled with the eccentric shaft of the impeller. The upper end of the planetary gears has an external gear structure. The external teeth of the planetary gears mesh with the internal teeth of the jet component based on the principle of gear transmission with fewer teeth, where the number of external teeth is less than the number of internal teeth. The lower end of the planetary gears is a cam 20, and the planetary gears are mounted on bushings. The planetary gear's cam structure is assembled with the radially extending ribs on the upper surface of the output wheel. The cam drives the output wheel to rotate at a uniform speed. The output wheel is mounted on a bushing, and there is a gap between the output wheel and the planetary gears to prevent interference. The output wheel is concentrically mounted on the central shaft. After the aforementioned low-tooth-difference speed reduction transmission, the output wheel converts to uniform circular motion, and its speed is significantly reduced compared to the impeller. The lower end face of the output wheel has a linkage part that engages with a groove on the oscillating component. The lower part of the oscillating component has a spherical structure and a connecting shaft structure. The spherical structure, in conjunction with a seal, achieves a dynamic seal during the oscillation process. This seal ensures the integrity of the water splash. Ultimately, under the action of the output wheel's rotation, the oscillating component can achieve a reciprocating cyclic oscillation with a certain designed angle. The oscillation angle is related to the axial distance between the linkage part and the central shaft. The outlet of this oscillating component can form a sheet of water. The oscillating component has a flow channel feature with a certain aspect ratio, an elliptical surface structure guiding the water flow to form a sheet of water, and an umbrella-shaped outlet structure with a certain angle.

[0047] Meanwhile, the structure of the water nozzle can also be replaced with other structures to achieve different oscillating water spray effects, such as: single jet water, shower water, blade water, etc. The housing is detachable and installed in the mounting cavity of the main body.

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.
