Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and in particular to a water outlet device. Background Technology

[0002] In related technologies, showerheads are common bathing products with a water spray function, but their water outlet angle and range are relatively fixed. Currently, to enrich the water spray patterns and provide users with a better water massage experience, various showerheads with massage effects are available on the market, such as microbubble water showerheads, mist water showerheads, granular water showerheads, and massage water showerheads. These showerheads use rotating baffles to periodically block the water outlets, creating a pulsed water flow to massage the user. However, current showerheads only have a single water outlet, resulting in poor adaptability to different scenarios and an inability to achieve dynamic water flow layering, thus reducing the user experience.

[0042] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0043] Please refer to Figures 1 to 4 This application provides a water outlet device, which includes a housing 10, a water outlet 20, a rotating frame 30, and a water baffle 40. The housing 10 has an inlet end 10a and an outlet end 10b opposite each other in the axial direction X, and the housing 10 forms a receiving cavity 10c between the inlet end 10a and the outlet end 10b. The water outlet 20 is installed on the outlet end 10b of the housing 10 and communicates with the receiving cavity 10c. The water outlet 20 is provided with at least two kinds of water outlet holes 21 so that water flows from the inlet end 10a into the receiving cavity 10c, then into the water outlet 20, and flows out from the water outlet holes 21 of the water outlet 20. The rotating frame 30 is rotatably disposed within the receiving cavity 10c; the water-blocking member 40 includes a water-blocking body 41 disposed within the water outlet 20 and at least two types of water-blocking strips 42 spaced apart around the water-blocking body 41. The water-blocking body 41 is connected to the rotating frame 30, so that the water-blocking body 41 can drive the water-blocking strips 42 to rotate, thereby causing the water-blocking strips 42 to periodically block the corresponding water outlet 21.

[0044] A water outlet 20 is installed at the water outlet end 10b of the housing 10, and at least two types of water outlet holes 21 are provided on the water outlet 20. A water-blocking body 41 is then installed inside the water outlet 20, and at least two types of water-blocking strips 42 are distributed circumferentially on the water-blocking body 41. When water flows from the water inlet end 10a into the receiving cavity 10c, the rotating frame 30 is driven to rotate, thereby driving the water-blocking body 41 to rotate. During the rotation, the water-blocking strips 42 periodically block the water flow at the corresponding water outlet hole 21, thus causing the water outlet 20 to produce intermittent water jets, making the water impact gap massage effect more comfortable. In other words, the water outlet device of this application, by providing multiple staggered water outlet holes 21 on the water outlet 20, and coordinating with the impact force of the water flow to drive the water-blocking body 41 to rotate, thereby driving the water-blocking strips 42 to rotate, so that different water-blocking strips 42 periodically block the corresponding water outlet holes 21, forms a water outlet partition design, realizing the superposition of dynamic water flow, which is beneficial to improving the user experience.

[0045] It should be noted that the water-blocking body 41 and the water-blocking strip 42 can be either a single piece or separate pieces. That is, the water-blocking body 41 and the water-blocking strip 42 can be manufactured using a one-piece molding process, or the water-blocking body 41 and the first water-blocking strip 42 can be formed as two separate components. Specifically, the water-blocking body 41 and the water-blocking strip 42 are molded separately and then connected to form the water-blocking component 40. In this embodiment, the water-blocking body 41 and the water-blocking component 40 are manufactured using a one-piece molding process, meaning the water-blocking body 41 and the water-blocking strip 42 are a single piece. This eliminates the need for a connection between the water-blocking body 41 and the water-blocking strip 42, ensuring the structural strength of the water-blocking component 40 and preventing the first water-blocking strip 42 from detaching under the impact of high-speed water flow.

[0046] For example, the periodic passage of the water-blocking strip 42 through the first water outlet 21a is achieved by the rotating frame 30 driving the water-blocking body 41 to rotate, and the water-blocking strip 42 rotates around the center of the water outlet 20 so that the water-blocking strip 42 rotates in the plane where the water outlet 21 is located, ensuring that the water-blocking strip 42 can periodically pass over the water outlet 21. That is, when the water-blocking strip 42 rotates to align with the water outlet 21, the water-blocking strip 42 will block part of the water outlet 21, and the water flow entering the water outlet 20 can still flow out of the unblocked part of the water outlet 21; when the water-blocking strip 42 rotates to form a misalignment with the water outlet 21, the water outlet 21 is in a fully open state, and the water flow in the water outlet 20 will flow out with a high impact force. In other words, as the rotating frame 30 drives the water-blocking body 41 to rotate, the water-blocking strip 42 will rotate with the water-blocking body 41, thereby alternately misaligning or aligning with the water outlet 21, so that the water outlet 20 produces an intermittent water jet effect.

[0047] In practical applications, the rotation of the rotating frame 30 can be driven by the flow rate of the water entering the receiving cavity 10c. The rotation speed of the rotating frame 30 can be adjusted by regulating the flow rate of the incoming water, thereby changing the pulse frequency of the water output to meet the needs of different users.

[0048] Furthermore, the "at least two types of water outlet holes 21" mentioned in this application refers to two or more types, which can be set according to the actual situation. The number of water-blocking strips 42 is determined according to the outlet holes set. That is, if two types of water outlet holes 21 are set, then two types of water-blocking strips 42 with different lengths are also required; if three types of water outlet holes 21 are set, then three types of water-blocking strips 42 with different lengths are also required, and so on. This will not be elaborated further.

[0049] Please refer to Figures 5 to 7 In practical applications, the water outlet 21 on the spout 20 has two types of outlet holes: a first outlet hole 21a and a second outlet hole 21b that are staggered and surround the center periphery of the spout 20. The first outlet hole 21a and the second outlet hole 21b are coaxially arranged, and the second outlet hole 21b is located inside the first outlet hole 21a. Correspondingly, the water-blocking strip 43 has two types: a first water-blocking strip 42a for blocking the first outlet hole 21a and a second water-blocking strip 42b for blocking the second outlet hole 21b. The second water-blocking strip 42b is located between two adjacent first water-blocking strips 42a. The rotation of the water-blocking body 41 enables the first water-blocking strips 42a and 42b to periodically block the first outlet hole 21a and the second outlet hole 21b, respectively.

[0050] In other words, in this embodiment, by setting a first water outlet 21a and a second water outlet 21b that are interlaced and surround the center periphery of the water outlet 20, and with the second water outlet 21b located inside the first water outlet 21a, and with the first water baffle 42a and the second water baffle 42b periodically passing through the first water outlet 21a and the second water outlet 21b respectively, the water flow of the first water outlet 21a and the second water outlet 21b is alternately blocked, thereby forming a dual-outlet partition design, realizing the superposition of dynamic water flow, which is beneficial to improving the user experience.

[0051] Since the second water outlet 21b is located inside the first water outlet 21a, and the second water-blocking strip 42b is used to block the second water outlet 21b, while the first water-blocking strip 42a is used to block the first water outlet 21a, the length of the second water-blocking strip 42b is less than the length of the first water-blocking strip 42a when extending outward from the center of the water-blocking body 41. This allows the second water-blocking strip 42b to effectively block the second water outlet 21b without being excessively long, thus saving manufacturing costs.

[0052] Please refer to Figure 2 and Figure 3 In one embodiment, the water outlet device further includes a planetary reduction mechanism 50, which includes a wheel frame 51 disposed within the receiving cavity 10c, a plurality of transmission gears 52, and an impeller 53. The inner side of the wheel frame 51 is provided with a transmission thread 512a; the plurality of transmission gears 52 are mounted on the rotating frame 30 and are used to mesh with the transmission thread 512a. The impeller 53 is located on the side of the wheel frame 51 near the water inlet end 10a, and the impeller extends into the wheel frame and is connected to the transmission gears 52 for transmission.

[0053] In this embodiment, the planetary reduction mechanism 50 converts the high-speed rotation impacted by the water flow into a low-speed, high-torque driving force to propel the rotating frame 30, ensuring stable and powerful rotation of the water-blocking body 41. The process by which the planetary reduction mechanism 50 drives the rotating frame 30 to rotate the water-blocking body 41 is as follows:

[0054] When water flows into the receiving cavity 10c from the inlet 10a, the impeller 53 rotates due to the impact of the water flow. Since the impeller 53 is connected to the transmission gear 52, which is mounted on the rotating frame 30 and connected to the transmission thread 512a, the transmission gear 52 is driven to rotate around the axis of the wheel frame 51, thereby driving the rotating frame 30 to rotate and drive the water baffle to rotate. During the rotation, the first water baffle 42 and the second water baffle 43 periodically pass through the water flow of the first water outlet 21a and the second water outlet 21b, respectively, so that the water outlet 20 produces intermittent water jets, making the water impact gap massage effect more comfortable and improving the user experience.

[0055] Furthermore, in this embodiment, the transmission gear 52 is cleverly meshed with the transmission thread, and the impeller 53 is connected to the transmission gear 52 to form a planetary reduction mechanism. This allows the high-speed rotational force of the impeller 53 under the impact of water flow to be transmitted through multiple stages to obtain a low-speed, high-torque driving force. Compared with the same working conditions, the water outlet speed is lower, the water impact gap massage effect is more comfortable, and the driving force is greater at a lower speed, which can greatly reduce the jamming phenomenon.

[0056] Please refer to Figure 3In one embodiment, the impeller 53 has a drive shaft 53a, one end of which, passing through the wheel frame 51, is connected to a connecting gear 54, which meshes with the drive gear 52. That is, by having the drive shaft 53a of the impeller 53 pass through the wheel frame 51 and extend towards the drive gear 52, and with the connecting gear 54 connected to the drive shaft 53a, the connecting gear 54 meshes with the drive gear 52. When the impeller 53 rotates due to the impact of water flow, the drive gear 52 is driven to rotate around the center of the wheel frame, thereby driving the rotating frame 30 to rotate and drive the water-blocking body 41. This allows the first water-blocking strip 42 to periodically cut off the water flow from the first water outlet 21a, causing the water outlet 20 to produce intermittent water jets.

[0057] Please refer to Figure 8 The impeller 53 includes a main body 511 and a first annular portion 512 located at one end of the main body 511 near the rotating frame 30. A first chamber A is formed between the first annular portion 512 and the main body 511, and a transmission thread 512a is located on the inner side of the first annular portion 512. In other words, by utilizing the first chamber A formed between the first annular portion 512 and the main body 511, and by having the transmission thread 512a located on the inner side of the first annular portion 512, the rotating frame 30 can be housed within the first chamber A for rotation, reducing water flow resistance and resulting in smoother rotation.

[0058] Please refer to Figure 8 and Figure 9 In one embodiment, the wheel frame 51 further includes a second annular portion 513, which is located at the end of the main body 511 away from the rotating frame 30. A second chamber is formed between the second annular portion 513 and the main body 511, and the impeller 53 is rotatably housed within the second chamber. The second annular portion 513 is provided with multiple drain outlets 513a at intervals to direct incoming water flow to the outlet 20. Thus, by providing the second annular portion 513 at the end of the main body 511 away from the rotating frame 30, a second chamber is formed between the second annular portion 513 and the main body 511. This allows the second chamber to serve as the working area of ​​the impeller 53 after it is subjected to the impact force of the water flow, preventing interference with the rotation process of the impeller 53. At the same time, the formed second chamber can increase the water pressure, ensuring smoother water flow to drive the impeller 53 and preventing insufficient water pressure from causing the impeller 53 to fail to rotate. In addition, the multiple drain outlets 513a distributed at intervals along the second annular portion 513 can ensure that the water flow from the second chamber B to the impeller 53 can be evenly radiated to the water outlet 20, avoiding local pressure concentration and scattering, while also ensuring that the water curtain covers all corners and improves the shower experience.

[0059] Please refer to Figure 10In one embodiment, the impeller 53 has a plurality of rolling portions 53b on its surface facing the main body 511. When the impeller 53 is housed within the second chamber, the rolling portions 53b roll in contact with the main body 511. In other words, by utilizing multiple rolling portions 53b distributed circumferentially around the impeller 53 to roll in contact with the main body 511, distributed load-bearing points can be formed, avoiding eccentric vibration caused by single-point overload. Furthermore, the clever arrangement of the rolling portions 53b transforms the friction between the impeller 53 and the main body 511 into rolling friction, effectively reducing wear between the impeller 53 and the main body 511 and extending their service life.

[0060] In one embodiment, the outlet end 10b of the housing 10 extends axially in the X direction to form a connecting portion 10d that communicates with the receiving cavity 10c, and the water outlet 20 is threadedly connected to the connecting portion 10d. That is, by connecting the water outlet end 10b of the housing 10 to the water outlet 20, it is ensured that the water outlet 20 and the housing 10 are coaxially mounted, eliminating the problem of uneven sealing caused by radial misalignment and reducing leakage at the connection between the water outlet 20 and the housing 10. Furthermore, a first sealing ring 80 is provided at the connection between the water outlet 20 and the connecting portion 10d to further enhance the sealing performance between the water outlet 20 and the connecting portion 10d.

[0061] In practical applications, because the water-blocking body 41 lacks a fixed axis of rotation, it may experience radial displacement under the influence of the rotating frame 30, thereby disrupting the consistency of the periodic interception of the water outlet by the water-blocking strip. Therefore, in one embodiment, the water outlet 20 has an inner cavity that communicates with the receiving cavity 10c and is used for water passage. A limiting post 60 is provided at the center of the bottom of the inner cavity. The water-blocking body 41 is fitted onto the limiting post 60, allowing it to rotate around the limiting post 60. This ensures that the water-blocking body 41 always revolves around the limiting post 60 during rotation, ensuring the temporal and spatial consistency of the periodic blocking of the water outlet and preventing turbulent pulse water flow due to eccentricity.

[0062] Please refer to Figure 1 and Figure 2 In one embodiment, the water outlet device further includes a water inlet connector 70, which is located at the water inlet end 10a of the housing 10 and is detachably connected to the housing 10. The water inlet connector 70 has a water passage cavity for water passage, and a plurality of inclined water holes 70b are provided at intervals at the bottom of the water passage cavity. The inclined water holes 70b are used to guide the water flow entering the water passage cavity to impact the impeller 53. The water inlet connector 70 is provided with a docking part 70a connected to the water passage cavity, which is used to connect to an external water inlet pipe.

[0063] Exemplarily, the water inlet connector 70 is detachably connected to the housing 10, so that the impeller 53, wheel frame 51, transmission gear 52, and connecting gear 54 are sealed within the receiving cavity 10c. Since the connector is detachably connected to the housing 10, it facilitates subsequent replacement or maintenance of the impeller 53, transmission gear 52, and connecting gear 54. The water inlet connector 70 has a mating portion 70a for connecting to an external pipeline. An external thread is provided on the outer surface of the mating portion 70a for quick connection to the external pipeline using a threaded connection. Furthermore, to drive the impeller 53 within the receiving cavity 10c to rotate, the water inlet connector 70 has a water passage cavity, and an inclined water hole 70b is provided at the bottom of the water passage cavity. This allows external water to enter the water passage cavity and be guided through the inclined water hole 70b to impact the impeller 53 within the receiving cavity 10c at an angle, thereby driving the impeller 53 to rotate.
