Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a swing water outlet mechanism and a water outlet device. Background Art

[0002] As consumers' demand for water output increases, more and more water outlet devices, such as shower heads and overhead showers, are equipped with massage functions, which are specifically derived into various swinging water sprays, so that the water sprayed on the human body can form a massage effect. Most of the swinging water outlet structures on the market are single-hole rotary types, and their spraying effects are limited.

[0003] Therefore, there is also a water outlet device with a swinging water splash, as disclosed in Chinese patent CN214077301U, which drives the impeller to rotate through the water flow, and the impeller drives the cam to rotate. The abutting protrusion of the swinging water outlet head squeezes the push rod and compresses the spring under the push of the cam. When the cam rotates to the other side, the compressed spring pushes the push rod, and the push rod pushes the abutting protrusion in the opposite direction, so that the swinging water outlet head swings and has an intermittent water outlet effect. In this scheme, although multiple water outlets can be driven to swing at the same time, the water flow drives the impeller, and the impeller directly drives the cam to rotate, which easily causes the water splash to swing too fast and the experience is poor. At the same time, in this scheme, the spring is reset, which is not only inconvenient to assemble, but also easy to affect the stability of the swing. Utility Model Content

[0004] The utility model discloses a swinging water outlet mechanism, aiming to improve the problems of too fast swing frequency and poor swing stability of the existing swinging water outlet structure.

[0010] As a further improvement, a water inlet channel is formed between the two driving parts of the swing member, and the water inlet channel is connected to the water hole on the turntable.

[0011] As a further improvement, the water outlet assembly also includes a water inlet member and a water pass member, the water inlet member is arranged below the turntable and is provided with a water inlet cavity, the swing member is arranged in the water inlet member, the water pass member is linked to the swing member and is provided with a water pass channel connected to the water inlet cavity, and the water outlet end of the water pass channel is used to be connected to the surface cover.

[0012] As a further improvement, a column is protrudingly provided on one side of the swinging member along the direction of the swinging axis, and a rotating part coaxially arranged with the column is provided on the other side relative to the column.

[0016] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0017] The water flow of the present application shoots out from the water injection holes to form an impact force on the blades of the impeller, thereby prompting the impeller to rotate, and then driving the sun gear to rotate. Among them, the ring gear is fixed, so that the planet gears rotate around the sun gear. At this time, the turntable is the follower of the planet gears, equivalent to the planet carrier, thus achieving speed reduction transmission.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Embodiment

[0032] Combined with Figures 1 to 15 , this embodiment provides a swing water outlet mechanism, including a housing 1, an impeller 2, a water outlet assembly and a speed - reducing transmission structure. Among them, the housing 1 is provided with a water inlet 11 and a water injection hole 12 communicated with the water inlet 11; the impeller 2 is arranged in the housing 1 and is configured to rotate under the impact of the water flow formed by the water injection hole 12; the water outlet assembly includes a swing member 31 and a face cover 32 provided with a plurality of water outlet nozzles 321; the speed - reducing transmission structure includes a ring gear 41, a sun gear 42, a planet gear 43 and a turntable 44. The ring gear 41 is assembled or formed inside the housing 1, the sun gear 42 is linked with the impeller 2, the planet gear 43 meshes with both the ring gear and the sun gear 42 to drive the turntable 44 to rotate. An eccentric part 441 adapted to the swing member 31 is arranged on the turntable 44 to drive the water outlet assembly to swing reciprocally, realizing the swing water outlet of the plurality of water outlet nozzles 321.

[0033] Exemplarily, a plurality of blades are arranged in a circumferential array on the impeller 2, and each blade is bent in the clockwise or counterclockwise direction. After the water flow enters from the water inlet 11 of the housing 1, it flows towards the water injection holes 12, and the impeller 2 rotates under the impact of the water flow generated at the water injection holes 12. In one implementation, a water injection plate 13 is provided inside the housing 1, and a plurality of water injection holes 12 are obliquely arranged on the water injection plate 13 for guiding the water flow to impact the impeller 2. It is easy to understand that the water flow is obliquely ejected from the water injection holes 12, thereby forming an impact force on the blades of the impeller 2, prompting the impeller 2 to rotate, and thus driving the sun gear 42 to rotate. Among them, the ring gear 41 is fixed, so that the planet gear 43 rotates around the sun gear 42. At this time, the turntable 44 is the follower of the planet gear 43, equivalent to the planet carrier, thereby realizing speed reduction transmission. The tooth numbers of the respective gears are set as the prior art and will not be elaborated here.

[0034] It should be noted that in this embodiment, by setting the speed reduction transmission structure, the rotational speed transmitted from the impeller 2 to the turntable 44 is decreased, thereby ensuring that the swing frequency is appropriate to enhance the user experience. In addition, in this embodiment, the eccentric part 441 drives the swing part 31 to reciprocally swing without a return spring. On the one hand, the structure is made more compact, the installation steps are simplified, and the installation efficiency is improved; on the other hand, the transmission is more stable through the gear meshing transmission method, and the stability of the swing can be ensured.

[0035] In a preferred embodiment, the ring gear 41 is formed on the inner wall of the housing 1, the sun gear 42 is coaxially arranged with the impeller 2, a rotating shaft 442 is provided on the turntable 44, and the planet gear 43 is sleeved on the rotating shaft 442. Further, two or three rotating shafts 442 can be provided on the turntable 44, and a planet gear 43 is provided on each rotating shaft 442 for adjusting the reduction ratio and further adjusting the frequency of the swinging water outlet. Among them, the ring gear 41 is formed on the inner wall of the housing 1, the sun gear 42 is coaxially arranged with the impeller 2, and when the impeller 2 rotates, it synchronously drives the sun gear 42 to rotate, making the structure more compact and reducing the space occupied by the swinging water outlet mechanism, thereby adapting to different water outlet bodies.

[0036] Based on the above embodiment, in an alternative embodiment of the present utility model, two driving parts 311 are arranged in parallel on the swing part 31, and the eccentric part 441 extends between the two driving parts 311 for alternately abutting against the two driving parts 311 to drive the water outlet assembly to swing. It is easy to understand that when the eccentric part 441 abuts against one side of the driving part 311, the swing part 31 swings towards that side.

[0037] Preferably, the swing member 31 is formed with a water inlet channel 312 between the two driving parts 311, and the water inlet channel 312 is connected to the water hole 443 on the rotating disk 44. Water flows from the water ejection hole 12 to the rotating disk 44, and flows from the water hole 443 on the rotating disk 44 to the water inlet channel 312. In this embodiment, the water inlet channel 312 is arranged between the two driving parts 311 to integrate the swing and the water inlet, reduce the space occupied by the water inlet channel 312, and make the structure of the swing member 31 more optimized.

[0038] In another embodiment, the water outlet assembly further includes a water inlet member 33 and a water passing member 34. The water inlet member 33 is disposed below the rotating disk 44 and is provided with a water inlet cavity 331. The swing member 31 is disposed in the water inlet member 33. The water passing member 34 is arranged in linkage with the swing member 31 and is provided with a water passing channel 341 communicating with the water inlet cavity 331. The water outlet end of the water passing channel 341 is used to connect with the face cover 32. Specifically, the water passing channel 341 includes a water inlet section extending along the swing axis, a water outlet section arranged parallel to the water inlet section, and a vertical section for connecting the water inlet section and the water outlet section. Exemplarily, the face cover 32 is fixed to the water outlet section by ultrasonic welding, and the water outlet nozzles 321 on the face cover 32 are arranged in the same extension direction as the water outlet section, so that the water outlet of each water outlet nozzle 321 is uniform.

[0039] In other embodiments, a column 313 is provided protrudingly along the direction of the swing axis on one side of the swing member 31, and a rotating portion 314 coaxially arranged with the column 313 is provided on the other side relative to the column 313. Preferably, the column 313 is accommodated in the receiving groove 335 of the water inlet member 33 and rotates, the rotating portion 314 is provided in a toothed shape, and the water inlet end of the water passing member 34 is sleeved in the water inlet member 33 and is engaged with the rotating portion 314 in a concave-convex manner. Thus, when the swing member 31 swings, the water passing member 34 is synchronously driven to swing.

[0040] Further, the other end of the face cover 32 opposite to the water passing member 34 is fixed to the connecting member 35. A first convex portion 342 for abutting against the inner wall of the housing 1 is provided on the outer wall of the water passing member 34 along the direction of the swing axis. A second convex portion 332 is arranged on the water inlet member 33 corresponding to the first convex portion 342, and the second convex portion 332 is accommodated in the rotation hole of the connecting member 35. It should be noted that in this embodiment, the water inlet section of the water passing member 34 is sleeved in the water inlet member 33 and connected to the swing member 31. A V-shaped ring 36 for sealing with the water inlet member 33 is sleeved on the outer wall of the water passing member 34. After the water flows into the water inlet cavity 331 of the water inlet member 33, it flows into the water passing channel 341 of the water passing member 34 through the water inlet channel 312 of the swing member 31. One end of the face cover 32 swings around the first convex portion 342 on the water passing member 34, and the other end swings around the second convex portion 332 along with the connecting member 35. The first convex portion 342 and the second convex portion 332 together constitute the effect of a swing axis. The face cover 32 and the connecting member 35 are connected by screws. A plurality of first screw holes 333 are evenly distributed on the water inlet member 33, and the housing 1 is provided with second screw holes 14 corresponding to the first screw holes 333.
