[0001] This utility model relates to the field of sanitary ware, and more specifically, to a water outlet device. Background Technology

[0002] As people's living standards improve, they have higher requirements for the comfort and functionality of showerheads. Existing pulsating showerheads generally have the following shortcomings: 1. Their structure is relatively complex; 2. The pulsation intensity is insufficient, resulting in a less noticeable experience.

[0003] To address the above problems, the inventors have provided a better solution. Utility Model Content

[0004] The purpose of this invention is to provide a water outlet device that can generate pulsating water spray, providing an excellent user experience and therapeutic effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water outlet device includes a water inlet base, a water distribution plate, an impeller, and a cover; wherein the water inlet base and the cover are fixedly connected to form a water passage cavity, the water inlet base includes an inlet end and an outlet end, the water distribution plate and the impeller are disposed in the water passage cavity, the water distribution plate includes an inlet hole, a side outlet hole, a central outlet hole and a return hole, the return hole communicates with the central outlet hole, the impeller is provided with a flow passage hole, which is coaxially connected to the central outlet hole, and the cover is disposed at the outlet end, including a water outlet nozzle, which is connected to the flow passage hole.

[0007] Preferably, the reflux hole and the central water outlet hole form a reflux cavity.

[0008] Preferably, the water inlet is connected to the side water outlet.

[0009] Preferably, the impeller includes blades and a shaft, and the shaft is provided with the flow passage hole and is connected to the water outlet.

[0010] Preferably, the blade is located in the upper half of the rotating shaft, and the lower half of the rotating shaft extends into the water outlet of the faceplate.

[0011] Preferably, the flow passage includes a direct flow section and an angled flow guide section. The angled flow guide section can guide the water flow to the inner wall of the nozzle on the cover, thus dispersing the water flow. At the same time, due to the continuous rotation of the impeller, pulsating particulate water is formed.

[0012] Preferably, the inner side of the water outlet of the faceplate is provided with a stepped flange, and the flange is provided with an inwardly tapering inner wall slope.

[0013] Preferably, the flow passage includes a direct flow section and a central guide section, wherein the central guide section is a circular hole that expands upward and narrows downward. When the water flows out through the outlet, it is pressurized and ejected through the central guide section of the flow passage. At the same time, due to the continuous rotation of the impeller, a strong pulsating impact water is generated.

[0014] Preferably, the inner side of the water outlet of the faceplate is provided with a stepped flange, and the flange has a downward vertical inner wall surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Water flows in through the inlet end of the inlet seat, passes through the inlet hole of the water distribution plate, and flows out from the side outlet hole. During its return flow through the return hole to the central outlet hole, the kinetic energy of the water impacts the impeller blades, driving the impeller to rotate. This, in turn, rotates the flow passage. Simultaneously, the impeller blades periodically obstruct and interrupt the water flow through the return hole, creating a pulsating effect in the water flowing out of the central outlet hole. This provides users with an excellent experience and therapeutic effect. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0032] like Figures 1 to 4 As shown, a water outlet device includes a water inlet seat 1, a water distribution plate 2, an impeller 3, and a cover 4.

[0033] The water inlet seat 1 includes an inlet end 11 and an outlet end 12. The inlet end 11 of the water inlet seat 1 is used to connect to the water supply pipe, and the outlet end 12 is fixedly connected to the cover 4 to form a water passage cavity 10.

[0034] The water distribution plate 2 and impeller 3 are disposed within the water passage cavity 10. The water distribution plate 2 includes a water inlet 21, a side water outlet 22, a central water outlet 23, and a return hole 24. The water inlet 21 is connected to the side water outlet 22. The return hole 24 is connected to the central water outlet 23, and the return hole 24 and the central water outlet 23 form a return cavity 20.

[0035] The impeller 3 is provided with a flow passage 30 and a coaxially connected center outlet 23.

[0036] The cover 4 is located at the water outlet 12 and includes a water outlet 41 and a connecting flow hole 30. Example 1

[0037] As one of the preferred embodiments, such as Figures 5 to 10As shown, the impeller 3 includes blades 31 and a shaft 32, with the blades 31 located in the upper half of the shaft 32, and the lower half of the shaft 32 extending into the outlet 41 of the cover 4. The inner side of the outlet 41 of the cover 41 has a stepped flange 411, and the flange 411 has an inwardly tapering inner wall slope 412. A Y-shaped sealing ring is located on the flange 411 between the outlet 41 and the lower half of the shaft 32. The shaft 32 has the aforementioned flow passage 30. The flow passage 30 includes a direct flow section 301 and an oblique flow guide section 302.

[0038] With the above structure, water flows in through the inlet end 11 of the inlet seat 1, through the inlet hole 21 of the water distribution plate 2, and out through the side outlet hole 22. During the process of returning to the center outlet hole 23 through the return hole 24, the water kinetic energy impacts the blades 31 of the impeller 3, driving the impeller 3 to rotate, thereby driving the flow passage 30 to rotate. At the same time, the blades 31 of the impeller periodically block and cut off the water flowing through the return hole 24, so that the water flowing out of the center outlet hole 23 produces a pulse effect. The inclined guide section 302 guides the water flow to the inclined inner wall 412 of the outlet 41 of the cover 4, so that the water flow is dispersed. At the same time, due to the continuous rotation of the impeller 3, under the action of centrifugal force, the dispersed water flow forms a relatively dispersed pulsating particle water with strong impact force.

[0039] The above-mentioned massage method has a significant effect. The pulsating water particles provide intermittent impacts to the skin, resulting in a relaxing massage and relieving muscle fatigue. Secondly, the strong impact of the pulsating water flow effectively cleanses the body. Thirdly, the design is simple. Example 2

[0040] As another preferred embodiment, such as Figures 11 to 13 As shown, the impeller 3 includes blades 31 and a rotating shaft 32, with the blades 31 located in the upper half of the rotating shaft 32, and the lower half of the rotating shaft 32 extending into the water outlet 41 of the cover 4. The inner side of the water outlet 41 of the cover 41 has a stepped flange 411, with a downwardly perpendicular inner wall surface 413. A Y-shaped sealing ring is located on the flange 411 between the water outlet 41 and the lower half of the rotating shaft 32. The rotating shaft 32 has the aforementioned flow passage 30.

[0041] The flow passage 30 includes a direct flow section 301 and a central guide section 303, the central guide section 303 being a circular hole that expands upwards and narrows downwards. With this structure, water flows in through the inlet end 11 of the inlet seat 1, through the inlet hole 21 of the water distribution plate 2, and out through the side outlet hole 22. During the process of returning to the central outlet hole 23 via the return hole 24, the kinetic energy of the water impacts the blades 31 of the impeller 3, driving the impeller 3 to rotate, thereby rotating the flow passage 30. Simultaneously, the impeller blades 31 periodically obstruct and interrupt the water flow through the return hole 24, creating a pulse effect in the water flow from the central outlet hole 23. When the water flows out through the outlet 41, it is pressurized and converged through the central guide section 303 of the flow passage 30 before being ejected. Furthermore, the continuous rotation of the impeller 3 creates a strong, pulsating impact water effect.

[0042] The above-mentioned massage method has a significant effect. The pulsating water provides intermittent impacts to the skin, resulting in a relaxing massage and relieving muscle fatigue. Secondly, the strong impact of the pulsating water flow effectively cleanses the body. Thirdly, the design is simple.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
