Description

Technical Field

[0001] This utility model relates to the field of bathtub nozzle technology, specifically a pulse nozzle with automatic water outlet switching. Background Technology

[0002] As the quality of home life continues to improve, people's functional needs for bathtubs have gradually expanded from simple cleaning to include comfortable spa and massage experiences. Currently, most common bathtub massage nozzles on the market use a fixed nozzle design, where water is sprayed out from the nozzle in a single direction with a constant intensity, forming a static water column. While this design is simple in structure and low in cost, it cannot flexibly change the water outlet position and mode according to the user's needs, making it difficult to meet diverse massage experience requirements.

[0003] To enhance the spa experience of bathtubs, the industry has introduced jet devices with rotating massage heads or adjustable water angles. However, most of these devices only achieve water jet rotation from a single outlet or can only switch between a fixed number of angles. Such devices can only change the water flow direction within a single nozzle, but cannot provide alternating sprays from multiple outlets simultaneously, nor can they achieve automatic outlet switching without the need for complex external valves or electric drives. This limits the effects of water pulses and multi-point massage.

[0004] Therefore, it is necessary to provide a bathtub pulse nozzle that is simple in structure, can automatically switch the spray position between the internal and external water outlets, and maintain a stable pulse massage effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pulse nozzle with automatic water outlet switching, which effectively improves the problems of some traditional bathtub massage nozzles, such as single water outlet, limited massage range, and reliance on external control for switching methods.

[0006] A pulse nozzle with automatic outlet switching includes a nozzle body, a nozzle cover, and a nozzle core seat. The nozzle cover has an inner outlet in its center and a predetermined number of outer outlets evenly distributed on its outer periphery. It also includes a rotating water outlet element, a water distribution plate, a predetermined number of outer guide pipes, and an intermediate guide component. The intermediate guide component includes a converging water outlet section and a predetermined number of intermediate guide pipes connected to the converging water outlet section. The rotating water outlet element is rotatably mounted within the nozzle core seat. The water outlet element includes a water outlet component, which includes a water inlet and a plurality of water outlet columns arranged in a ring and uniformly connected to the water inlet. The water outlet columns are located near the side of the water distribution plate. The water distribution plate is provided with a plurality of openings arranged in a ring. The end of the opening away from the rotating water outlet element is connected to the intermediate guide pipe and the outer guide pipe at intervals. The side of the converging water outlet away from the opening is connected to the inner water outlet, and the end of the outer guide pipe away from the opening is connected to the outer water outlet.

[0007] Preferably, the rotating water outlet element further includes a rotating shaft, which is disposed on the central axis of the water outlet component with both ends extending out of the water outlet component. The two ends of the rotating shaft are rotatably connected to the nozzle core seat and the water distribution plate, respectively.

[0008] Furthermore, the nozzle core seat includes a core seat body and a core base. A core seat water inlet is provided on the bottom side of the core seat body, and a core seat air inlet is provided on the middle side of the core seat body. The core base is detachably provided on the bottom of the core seat body.

[0009] Furthermore, the water distribution plate includes a plate body, and the outer periphery of the plate body is provided with annularly arranged openings. A columnar receiving cavity extends upward from the periphery of the openings, and the columnar receiving cavity is used to install the intermediate guide pipe and the outer guide pipe.

[0010] Furthermore, a plurality of first connecting posts are provided on the side of the disc body near the cylindrical receiving cavity, and a plurality of second connecting posts are provided on the nozzle cover to be inserted and connected to the first connecting posts.

[0011] Furthermore, a rotating hole is provided at the center of the side of the disc away from the cylindrical receiving cavity and at the center of the core base, which is rotatably connected to the rotating shaft.

[0012] Preferably, the number of the intermediate guide pipe, the outer guide pipe, and the water outlet column are the same.

[0013] Preferably, there are three intermediate guide pipes, three outer guide pipes, and three water outlet columns.

[0014] Preferably, a water outlet column is provided inside the core body, and the water inlet is sleeved on the water outlet column.

[0015] Preferably, the nozzle body includes a water inlet end and an opposite spray end. The water inlet end is provided with a water inlet port and an air inlet port, which are offset relative to each other. The spray end forms a receiving through hole for inserting the nozzle core seat, and the nozzle cover is installed at the open end of the receiving through hole.

[0016] Preferably, it also includes a fastener with an internal thread, and an external thread on the outer side of the nozzle body. The fastener, together with the nozzle cover, clamps the nozzle body for installation and fixation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a pulse nozzle with automatic outlet switching. By setting an inner outlet in the center of the nozzle cover and evenly distributing multiple outer outlets around the periphery, and combining this with a rotating water outlet element, a water distribution plate, a central guide element, and multiple guide pipes, the rotating water outlet element can be driven to rotate using the kinetic energy of the water flow itself, without the need for external control. This causes multiple water jets on the water outlet element to align sequentially with openings on the water distribution plate, thereby achieving automatic switching of the water flow path between the central and outer guide pipes, ultimately creating an automatic alternating spray effect between the inner and outer outlets. This structural design not only effectively expands the massage coverage area of ​​the nozzle but also creates a rhythmic and directional pulsed water flow, significantly enhancing the massage stimulation and comfort. Furthermore, because this device requires no complex control structure, its overall structure is compact, easy to install, and highly stable, making it widely applicable. Attached Figure Description

Detailed Implementation

[0029] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] See Figures 1 to 8 This embodiment provides a pulse nozzle with automatic outlet switching, comprising a nozzle body 10, a nozzle cover 20, and a nozzle core seat 30. The nozzle cover 20 has an inner outlet 21 in its center, and a predetermined number of outer outlets 22 are evenly distributed on its outer periphery. It also includes a rotating water outlet element 40, a water distribution plate 50, a predetermined number of outer guide pipes 60, and an intermediate guide component 70 (see reference). Figure 7 The intermediate guide member 70 includes a water outlet section 71 and a predetermined number of intermediate guide pipes 72 connected to the water outlet section 71. The rotating water outlet element 40 is rotatably disposed within the nozzle core seat 30. The rotating water outlet element 40 includes a water outlet element 41 (see...). Figure 8The water outlet component 41 includes a water inlet 42 and a plurality of water outlet columns 43 arranged in a ring and uniformly connected to the water inlet 42. The water outlet columns 43 are arranged near the side of the water distribution plate 50. The water distribution plate 50 is provided with a plurality of openings 51 arranged in a ring. The end of the opening 51 away from the rotating water outlet component 40 is connected to the intermediate guide pipe 72 and the outer guide pipe 60 at intervals. The side of the converging water outlet 71 away from the opening 51 is connected to the inner water outlet 21. The end of the outer guide pipe 60 away from the opening 51 is connected to the outer water outlet 22.

[0031] Preferably, the rotating water outlet element 40 further includes a rotating shaft 44, which is disposed on the central axis of the water outlet element 41 with both ends extending out of the water outlet element 41. The two ends of the rotating shaft 44 are rotatably connected to the nozzle core seat 30 and the water distribution plate 50, respectively. The arrangement of the rotating shaft 44 allows the rotating water outlet element 40 to rotate stably around the central axis under the impact of water flow, thereby driving the water outlet column 43 to align sequentially with the opening 51 on the water distribution plate 50, realizing the periodic switching of the water flow path. Through the intermittent alignment of the water outlet column 43 with the opening 51, an alternating pulse jet effect can be formed, so that the water flow can be automatically switched between the outer water outlet 22 and the inner water outlet 21, which not only improves the diversity and fun of use, but also enhances the massage effect and comfort of the nozzle.

[0032] Preferably, the nozzle body 10 includes a water inlet end and an opposite spray end. The water inlet end is provided with a water inlet 11 and an air inlet 12. The water inlet 11 and the air inlet 12 are offset from each other, which can introduce air while the water flows into the nozzle body 10, forming a water-air mixing effect and improving the softness and massage sensation of the water. The spray end is formed with a receiving through hole 13 for inserting the nozzle core seat 30, ensuring that the nozzle core seat 30 can be stably installed into the receiving through hole 13 during the assembly process. The nozzle cover 20 is installed at the open end of the receiving through hole 13 to achieve overall sealing and aesthetics. Furthermore, the nozzle core seat 30 includes a core seat body 31 and a core base 32. The bottom side of the core seat body 31 is provided with a core seat water inlet 33 for receiving water from the nozzle body 10; the middle side is provided with a core seat air inlet 34 for guiding external air entering through the air inlet 12 of the nozzle body 10 into the internal water flow path, enhancing the water flow pulse effect. The core base 32 is detachably mounted on the bottom of the core seat body 31 for easy maintenance. In this embodiment, the core base 32 and the core seat body 31 are connected by a snap-fit ​​mechanism, making installation convenient and quick. Disassembly and assembly can be completed without tools, effectively improving the maintainability and ease of use of the structure.

[0033] Furthermore, the water distribution plate 50 includes a plate body, with annularly arranged openings 51 on the outer periphery of the plate body. A columnar receiving cavity 52 extends upward from the periphery of each opening 51, and the columnar receiving cavity 52 is used to install the intermediate guide pipe 72 and the outer guide pipe 60. The arrangement of the water distribution plate 50 allows for stable connection and flow guidance with the water outlet column 43; simultaneously, the height of the columnar receiving cavity 52 matches the insertion force of the guide pipe, ensuring reliable fixation of the guide pipe after installation and contributing to stable water flow transmission.

[0034] Furthermore, a plurality of first connecting posts 53 are provided on the side of the disc body near the cylindrical receiving cavity 52, and a plurality of second connecting posts 14 are provided on the nozzle cover 20 to be inserted and connected to the first connecting posts 53. This enables rapid positioning and stable assembly between the nozzle cover 20 and the water distribution disc 50, effectively preventing structural loosening or misalignment caused by water flow impact or vibration during use.

[0035] Furthermore, a rotating hole 54 is provided at the center of the side of the disc away from the cylindrical receiving cavity 52 and at the center of the core base 32, which is rotatably connected to the rotating shaft 44. The two rotating holes 54 respectively provide axial limiting and radial support for the upper and lower ends of the rotating shaft 44, so that the rotating water outlet element 40 can rotate stably around the rotating shaft 44, thereby ensuring that the rotational movement of the water outlet element 41 under the action of water flow is more stable and reliable, and avoiding the occurrence of shaking, jamming and other phenomena.

[0036] Preferably, the number of the intermediate guide pipe 72, the outer guide pipe 60, and the water outlet column 43 are the same. This consistent number design ensures that the rotating water outlet element 40 achieves precise alignment of the water outlet column 43 with the opening 51 of the water distribution plate 50 during each rotation. That is, the water outlet column 43 will simultaneously align with either the opening 51 of the water distribution plate 50 connected to the intermediate guide pipe 72 or the opening 51 of the water distribution plate 50 connected to the outer guide pipe 60. This allows the water flow to switch rhythmically between the intermediate and outer guides, forming a stable and directional pulse jet effect. Furthermore, there are three of each of the intermediate guide pipe 72, the outer guide pipe 60, and the water outlet column 43.

[0037] Preferably, a water outlet column 35 is provided inside the core seat body 31, and the water inlet 42 is rotatably sleeved on the water outlet column 35. This arrangement facilitates the smooth guidance of water entering from the core seat inlet 33 through the water outlet column 35 to the water inlet 42 of the rotating water outlet element 40, achieving efficient water delivery and uniform distribution, and ensuring the stable rotation of the rotating water outlet element 40 and the continuity and consistency of the pulse jet effect.

[0038] Preferably, it also includes a fastener 15 with an internal thread, and an external thread is provided on the outer side of the nozzle body 10. The fastener 15 cooperates with the nozzle cover 20 to clamp the nozzle body 10 for installation and fixation.

[0039] It should be noted that during use, water enters through the inlet 11 of the nozzle body 10, while air is introduced through the air inlet 12, achieving water-air mixing and improving the gentleness of the water flow and the massage effect. After entering the nozzle core seat 30, the water first flows through the core seat inlet 33 into the water outlet column 35 set inside the core seat body 31, and then enters the water inlet 42 of the rotating water outlet element 40 sleeved on the water outlet column 35. Air is introduced through the air inlet 12 from the core seat air inlet 34. After the water flow reaches the core seat body 31, the Venturi effect draws in air, forming a water-air mixed water flow, and then the water flow pushes the rotating water outlet element 40 to rotate stably. As the rotating water outlet element 40 rotates, the water column 43 aligns sequentially with the annularly arranged openings 51 on the water distribution plate 50. The openings 51 of the water distribution plate 50 are alternately connected to the intermediate guide pipe 72 and the outer guide pipe 60. When the water column 43 aligns with the opening 51 connected to the intermediate guide pipe 72, the water flows through the intermediate guide pipe 72 to the inner water outlet 21 of the nozzle cover 20, achieving spraying from the inner water outlet 21. When the water column 43 rotates to align with the opening 51 connected to the outer guide pipe 60, the water flows through the outer guide pipe 60 to multiple outer water outlets 22 of the nozzle cover 20, achieving spraying from the outer water outlets 22. As the rotating water outlet element 40 drives the water column 43 to align with different guide pipe openings 51 in sequence, the water flow path switches periodically, achieving alternating pulse spraying between the inner water outlet 21 and the outer water outlet 22. This pulse spraying method not only expands the spray coverage area but also forms a rhythmic, alternating pulse water flow, enhancing the massage stimulation and comfort experience. In addition, the entire switching process is completed by the water flow itself, without the need for external power or control devices, and the structure is simple and stable.

[0040] This invention provides a pulse nozzle with automatic outlet switching. By setting an inner outlet 21 in the center of the nozzle cover 20 and evenly distributing multiple outer outlets 22 on the outer periphery, and combining this with the coordinated operation of a rotating water outlet element 40, a water distribution plate 50, an intermediate guide element 70, and multiple guide pipes, the rotating water outlet element 40 can be driven to rotate using the kinetic energy of the water flow itself, without the need for external control structures. This causes multiple water jets 43 on the water outlet element 41 to align sequentially with the openings 51 on the water distribution plate 50, thereby achieving automatic switching of the water flow path between the intermediate guide pipe 72 and the outer guide pipe 60, ultimately creating an automatic alternating spray effect between the inner outlet 21 and the outer outlets 22. This structural design not only effectively expands the massage coverage area of ​​the nozzle but also creates a rhythmic and directional pulse water flow, significantly enhancing the massage stimulation and comfort. Furthermore, because this device requires no complex control structure, its overall structure is compact, easy to install, and highly stable, making it widely applicable.

[0041] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
