Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and more specifically, to a swing-out water outlet structure. Background Technology

[0002] Traditional oscillating water systems mostly use parallel-placed impellers to drive planetary gear trains, converting circular motion into oscillating water outlets. For example, Chinese patent CN212916166U discloses a water outlet structure with dynamic water spray, where the impeller, first gear, internal gear, and rotating disk rotate coaxially, with each axis parallel to the water inlet direction. This means the impeller, first gear, internal gear, and rotating disk are placed perpendicular to the water inlet direction. Therefore, during rotation, water pressure acts on the entire plane perpendicular to the water flow direction, resulting in significant friction that each component needs to overcome. Consequently, the required starting water pressure is also high, easily leading to unstable water outlet performance. Furthermore, some oscillating water structures involve multiple changes in water flow direction between the inlet and outlet. This cyclical flow consumes energy, resulting in insufficient impact force of the water sprayed from the outlet and a significant decrease in water output, which is detrimental to user experience. Summary of the Invention

[0003] This invention discloses a swing water outlet structure, which aims to improve the problems of high starting water pressure and insufficient water flow impact force required by existing swing water structures.

[0004] The present invention adopts the following solution:

[0005] A swing-type water outlet structure includes a body, the body having a water inlet and a water passage cavity and a water outlet disposed along the same axis;

[0006] The water passage cavity is provided with a first inclined water body, an impeller, and a reduction mechanism arranged sequentially along the water flow direction. The first inclined water body is used to form an inclined water flow that impacts the rotation of the impeller. The impeller and the reduction mechanism are linked and their rotation axes are perpendicular to the axis, so that the end faces of the impeller and the reduction mechanism are parallel to the water flow direction. A water outlet is provided on the water outlet. When water enters, the impeller drives the reduction mechanism to rotate, so that the eccentric part on the reduction mechanism drives the water outlet to oscillate periodically.

[0007] As a further improvement, the water outlet has an upwardly extending swing portion, and the eccentric portion is columnar and inserted into the U-shaped groove of the swing portion.

[0008] As a further improvement, the reduction mechanism includes a driving gear coaxially arranged with the impeller and a driven gear meshing with the driving gear, and the eccentric portion protrudes from the end face of the driven gear.

[0009] As a further improvement, both the deceleration mechanism and the impeller are mounted on a bracket, which is inserted into a slot in the body and pressed axially by the first inclined water body.

[0010] As a further improvement, the spout has a bowl-shaped rotating part, and swing shafts are formed on both sides of the rotating part. The swing shafts are installed in the mounting groove of the body so that the spout can be swingably mounted on the water outlet.

[0011] As a further improvement, a water outlet hole is provided along the middle of the water outlet, and a sealing element for sealing with the water outlet is provided on the outer periphery of the water outlet.

[0012] As a further improvement, one end of the water outlet is closed, and the water flows along the outer wall of the water outlet. The bottom of the water outlet has an outwardly extending guide portion so that the water flowing out along the outer wall of the water outlet can converge on the guide portion and form a water column with the same angle as the guide portion.

[0013] As a further improvement, the drainage part is made of soft rubber.

[0014] As a further improvement, a shell is fitted on the outside of the main body, and a second inclined water body and a rotating wheel are configured at the water inlet end of the shell. The second inclined water body is used to form an oblique water flow that impacts the rotation of the rotating wheel. The rotating wheel is fixedly connected to the main body. When water enters, the main body rotates synchronously with the rotating wheel, thereby forming a combination of swaying and spiraling water splashes.

[0015] As a further improvement, at least a ring of steel balls is arranged in the circumferential direction between the contact surfaces of the body and the shell and / or between the sidewall surfaces of the body and the shell.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] 1. In this application, the impeller and reduction mechanism shafts are both perpendicular to the water flow direction, and the end faces of the impeller and reduction mechanism are parallel to the water flow direction. This reduces the force-bearing area of ​​the impeller and reduction mechanism, thereby reducing the frictional force that the impeller and reduction mechanism need to overcome during rotation. They only need to overcome the frictional force on the shaft. Compared with the existing structure where the shaft is placed parallel, the frictional force is smaller, making rotation easier and allowing for lower starting water pressure, thus ensuring stable water output. Furthermore, the water passage chamber and outlet are arranged along the same axis, saving space and allowing for a smaller overall size of the oscillating water system. The water flows directly to the outlet through the inclined water body without multiple turns, avoiding flow loss and ensuring the impact force of the water flow for optimal water output.

[0018] 2. One end of the spout is closed, and there is no seal on its outer circumference. Water flows out from the gap between the spout and the outlet. Because the water flows along the outer wall of the spout, the outer wall of the spout does not contact the wall of the outlet during water flow, creating a suspended state for the spout. This reduces the resistance during the spout's oscillation and ensures the oscillation efficiency of the spout. Furthermore, the water flow covers the entire outer wall of the spout during flow. This novel water flow method provides a good visual effect from the user's perspective, enhancing the aesthetics of the oscillating water.

[0019] 3. The outer side of the main body is fitted with a shell, and the water inlet end of the shell is equipped with a second inclined water body and a rotating wheel. When water enters, the main body rotates synchronously with the rotating wheel, thereby forming a combination of swaying and spiraling water splashes, making the shape of the water splashes more dynamic and beautiful.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. 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. 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.

[0046] The terms “top,” “bottom,” “upper,” “lower,” “left,” “right,” “front,” “back,” and similar expressions used in this document are for illustrative purposes only. The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0047] Combination Figures 1 to 8 This embodiment provides a swinging water outlet structure, including a body 1, which has an inlet 11 and a water passage cavity 12 and an outlet 13 arranged along the same axis. The water passage cavity 12 is arranged in sequence along the water flow direction, including a first inclined water body 2, an impeller 3 and a reduction mechanism 4. The first inclined water body 2 is used to form an inclined water flow that impacts the rotation of the impeller 3. The impeller 3 and the reduction mechanism 4 are linked and their rotation axes are perpendicular to the axis, so that the end faces of the impeller 3 and the reduction mechanism 4 are parallel to the water flow direction. The outlet 13 is equipped with a water nozzle 5. When water enters, the impeller 3 drives the reduction mechanism 4 to rotate, so that the eccentric part 41 on the reduction mechanism 4 drives the water nozzle 5 to swing periodically.

[0048] For example, the first inclined water body 2 has two or more inclined water inlets 21 to form an inclined water flow that impacts the blades of the impeller 3. When the impeller 3 rotates, the eccentric part 41 on the reduction mechanism 4 drives the water outlet 5 to swing left and right, thereby forming a wave-shaped water splash that swings with the water outlet 5.

[0049] It should be noted that in this embodiment, the shafts of both the impeller 3 and the reduction mechanism 4 are perpendicular to the water flow direction, and the end faces of the impeller 3 and the reduction mechanism 4 are parallel to the water flow direction. This reduces the force-bearing area of ​​the impeller 3 and the reduction mechanism 4, thereby reducing the frictional force that the impeller 3 and the reduction mechanism 4 need to overcome when rotating. They only need to overcome the frictional force on the shaft. Compared with the parallel shaft placement structure in the prior art, the frictional force to overcome is smaller, making rotation easier and allowing for lower starting water pressure, thus ensuring water output stability. Furthermore, the water passage chamber 12 and the outlet 13 are both arranged along the same axis, saving space and allowing for a smaller overall size of the oscillating water system. The water flows directly to the outlet 13 through the inclined water body without multiple turns, avoiding water flow loss and ensuring the impact force of the water flow, thus guaranteeing the water output effect. Preferably, the inlet 11 and the outlet 13 are also arranged on the same axis to further reduce the structural space.

[0050] In a preferred embodiment, the water outlet 5 has an upwardly extending swing portion 51, and an eccentric portion 41 is columnar and inserted into the U-shaped groove 511 of the swing portion 51. When the deceleration mechanism 4 rotates, it drives the eccentric portion 41 to rotate synchronously, so that the eccentric portion 41 abuts against the groove wall of the U-shaped groove 511, causing the swing portion 51 to drive the water outlet 5 to swing left and right.

[0051] Furthermore, the spout 5 has a bowl-shaped rotating part 52, and swing shafts 53 are formed on both sides of the rotating part 52. The swing shafts 53 are installed in the mounting groove 14 of the main body 1 so that the spout 5 can be swingably mounted on the outlet 13. The mounting groove 14 is a C-shaped groove to facilitate the insertion of the swing shafts 53. The arrangement of the rotating part 52 ensures that the swing part 51 drives the spout 5 to swing, reducing swing resistance.

[0052] In one embodiment, a water outlet 54 is provided along the middle of the water outlet 5, and a sealing member 55 is disposed on the outer periphery of the water outlet 5 to seal with the water outlet 13, so that water flows out from the water outlet 54. Preferably, see... Figure 16 Multiple water outlets can be provided in the water outlet 5 to create a dense, swirling water flow, thereby improving the water output effect. In a preferred embodiment, combined with... Figures 17 to 19 A spiral body 57 is provided inside the water outlet 5. The spiral body 57 is provided with a spiral groove 571 that communicates with the water outlet 54. After the water flows into the spiral groove 571 and rotates and accelerates, it flows out from the water outlet 54, forming a splashing and swaying water to further enrich the water outlet pattern.

[0053] Reference Figure 9In another embodiment, one end of the spout 5 is closed, and the water flows along the outer wall of the spout 5. In this case, no seal 55 is provided on the outer periphery of the spout 5, and the water flows out from the gap between the spout 5 and the outlet 13. Because the water flows out along the outer wall of the spout 5, the outer wall of the spout 5 does not contact the wall of the outlet 13 during the water flow state, thereby reducing the resistance of the spout 5 during the oscillation process and ensuring the oscillation efficiency of the spout 5. Furthermore, the water flow covers the entire outer wall of the spout 5 during water flow; this water flow method is novel, provides a good visual effect of the spout 5 from the user's perspective, and enhances the aesthetics of the oscillating water.

[0054] Preferably, refer to Figure 10 and Figure 11 The bottom of the spout 5 has an outwardly extending guide portion 56, allowing water flowing out along the outer wall of the spout 5 to converge on the guide portion 56 and form a water column at the same angle as the guide portion 56. The shape, length, and angle of the guide portion 56 can be set according to the desired water pattern, thereby creating different oscillating water states to enrich the shape of the water splash. A groove 521, similar in shape to the rotating part 52, can also be provided on the side of the spout 5 facing the water passage cavity 12 to reduce the weight of the spout 5 and ensure smooth rotation of the spout 5. Figure 14 and Figure 15 In other embodiments, the spout 5 is conical, with a guide portion 56 located at the tip of the cone. Water can flow along the conical wall to the guide portion 56, resulting in a more stable water flow effect. Furthermore, the guide portion 56 is made of soft rubber. During the oscillation of the spout 5, water flows out along the soft guide portion 56, making the water droplets gentler and preventing splashing. The guide portion 56 can be formed by secondary rubber coating, but is not limited to this and is not specifically restricted.

[0055] Based on the above embodiments, in an optional embodiment of the present invention, the reduction mechanism 4 includes a driving gear 42 coaxially arranged with the impeller 3 and a driven gear 43 meshing with the driving gear 42, with an eccentric portion 41 protruding from the end face of the driven gear 43. The reduction mechanism 4 adopts a gear mechanism, which can ensure smooth operation. Preferably, both the reduction mechanism 4 and the impeller 3 are arranged on a bracket 44, which is inserted into the slot 15 of the body 1 and pressed by the first inclined body 2 to limit axial movement. During installation, the impeller 3 and the driving gear 42 are first fitted onto the first rotating shaft 441 of the bracket 44, and the driven gear 43 is fitted onto the second rotating shaft 442 of the bracket 44, so that the impeller 3 and the reduction mechanism 4 and the bracket 44 form an assembly module, and then this assembly module is inserted into the slot 15. The U-shaped groove 511, the mounting groove 14 and the slot 15 are all designed to facilitate top-to-bottom assembly and disassembly. Preferably, the first rotating shaft 441 and the second rotating shaft 442 are forcibly detached from the gear to prevent the gear disk from dislodging during movement. The first inclined water body 2 can be fixed to the body 1 by means of clips, screws, or other structures, without specific limitations.

[0056] In other embodiments, a baffle 22 is provided on the first inclined water body 2, and a positioning groove 221 is provided on the baffle 22. During installation, the positioning groove 221 will be inserted into the first rotating shaft 441 and block the impeller 3 or the drive gear 42 in front of it, so as to prevent the impeller 3 from falling out during operation.

[0057] Based on the above embodiments, in an optional embodiment of the present invention, referring to Figure 12 and Figure 13 The outer side of the main body 1 is fitted with a shell 6. The water inlet end of the shell 6 is equipped with a second inclined water body 61 and a rotating wheel 62. The second inclined water body 61 forms an oblique water flow that impacts the rotation of the rotating wheel 62. The rotating wheel 62 is fixedly connected to the main body 1. When water enters, the main body 1 rotates synchronously with the rotating wheel 62, thereby forming a combination of swaying and spiraling water splashes. The rotating wheel 62 and the main body 1 can be fixed together by welding or tight fitting, and sealed by a sealing ring 63, preferably an O-type, Y-type, or X-type. It is easy to understand that in this embodiment, by setting the second inclined water body 61 and the rotating wheel 62 on the shell 6 to drive the entire swaying water outlet structure in a circular motion, rotation can be added to the swaying water splashes, forming a spiral swaying water splash, making the shape of the water splashes more dynamic and aesthetically pleasing.

[0058] Furthermore, at least one ring of steel balls 64 is arranged circumferentially between the contact surfaces of the body 1 and the shell 6 and / or between the sidewalls of the body 1 and the shell 6. The arrangement of the steel balls 64 can reduce the friction between the body 1 and the shell 6 during circumferential movement, play a lubricating role, and also prevent wear between the body 1 and the shell 6 during rotation, thus ensuring the service life of the water outlet structure.

[0059] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
