[0015] Furthermore, the height of the water spray forming hole is 3 to 5 times the diameter of the water outlet end of the jet hole.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figures 1-15 A shower head includes a water outlet device; the water outlet device includes a water spray switching component 1, a water distribution component 2, and a water outlet element 3, the water outlet element 3 having a water outlet hole 31; the output end of the water spray switching component 1 is rotatably connected to the water distribution component 2, and the output end of the water spray switching component 1 has a guide port 11; when the water spray switching component 1 rotates relative to the water distribution component 2, the guide port 11 enables water to flow along the radial and / or axial direction of the water distribution component 2 and enter the water outlet hole 31, so as to form different water sprays that appear alternately or simultaneously.

[0027] It is understandable that by rotating the water flow-driven water spray switching component 1 relative to the water distribution component 2, the flow direction of the guide port 11 can be changed, so that the water flows from the water distribution component 2 into the water outlet 31 and / or through the water distribution component 2 and then into the water outlet 31 from the water outlet component 3, thereby forming water sprays of different shapes. As the guide port 11 keeps changing its position, different water sprays will appear alternately, thus making the massage effect more significant.

[0028] In some embodiments, the water distribution component 2 includes a first water distribution channel 21 at least partially distributed radially along the water distribution component 2 and a second water distribution channel 22 at least partially distributed axially along the water distribution component 2. When the guide port 11 communicates with the water outlet 31 through the first water distribution channel 21, a first water splash is formed; when the guide port 11 communicates with the water outlet 31 through the second water distribution channel 22, a second water splash is formed. The first water distribution channel 21 is formed to decelerate the water flow, while the second water distribution channel 22 is set to accelerate the water flow. The two water flows with different flow velocities collide with the inner wall of the corresponding water outlet 31 to form first and second water splashes with different shapes. The difference in flow velocity and shape between the first and second water splashes provides a massage effect to the user.

[0029] In some embodiments, the water distribution assembly 2 includes an upper water distribution plate 23 and a lower water distribution plate 24; the lower water distribution plate 24 has a water distribution plate surrounding wall 241; the water distribution plate surrounding wall 241, together with the upper water distribution plate 23 and the lower water distribution plate 24, forms a water distribution cavity 25; a first water distribution port 251 is provided on the side wall of the water distribution cavity 25, and a second water distribution port 252 is provided on the bottom wall of the water distribution cavity 25; on the rotation path of the guide port 11, the first water distribution port 251 and the second water distribution port 252 are staggered so that the guide port 11 is alternately connected with the first water distribution port 251 and the second water distribution port 252, thereby causing the first water splash and the second water splash to appear alternately. Optionally, multiple first water distribution ports 251 and second water distribution ports 252 can be provided. Preferably, two first water distribution ports 251 and two second water distribution ports 252 are provided, with the two first water distribution ports 251 and the two second water distribution ports 252 located on the same straight line, so that the first water distribution ports 251 and the second water distribution ports 252 are alternately arranged on the rotation path of the guide port 11. Further, taking the guide port 11 being completely aligned with the first water distribution port 251 as an example, the water distribution port connected to the guide port 11 will switch every quarter circumference when the guide port 11 rotates. When the circumferential length of the guide port is large, the guide port 11 may be connected to the first water distribution port 251 and the second water distribution port 252 at the same time. In this case, the distance between the first water distribution port 251 and the second water distribution port 252 in the rotation direction of the guide port 11 should be less than the circumferential length of the guide port 11. In addition, when there are more than two guide ports 11, or when there are more than two first water distribution ports 251 and / or second water distribution ports 252, different guide ports 11 may be connected to the first water distribution port 251 and the second water distribution port 252 at the same time. In the above two cases, the water flow will interact with each other and be discharged from the corresponding water outlet 31. The water droplets discharged are different, and the shape of the water droplets is between the first water droplet and the second water droplet. Furthermore, the water distribution plate wall 241 has a protrusion that bulges outward in a direction away from the central axis of the water distribution plate wall 241, and the second water outlet 252 is located on the protrusion, such that the first water outlet 251 and the second water outlet 252 are misaligned in the outward convex direction of the protrusion, that is, the distance from the first water outlet 251 to the central axis of the water distribution cavity 25 is less than the distance from the second water outlet 252 to the central axis of the water distribution cavity 25.

[0030] In some embodiments, a drain hole 242 is provided on the lower water distribution plate 24; the drain hole 242 and the first water outlet 251 are located on the first water distribution channel 21, so that the first water outlet 251 is connected to the water outlet 31 through the drain hole 242. The drain hole 242 is provided to extend the length of the water flow along the axial direction of the water distribution component 2, thereby sufficiently slowing down the water flow and widening the difference in the forming effect between the first water splash and the second water splash, so as to improve the massage experience. Preferably, multiple drain holes 242 are provided, and all drain holes 242 are evenly distributed along the circumference of the lower water distribution plate 24, and the drain holes 242 are located near the outer edge of the lower water distribution plate 24.

[0031] In some embodiments, the water outlet device further includes a rear cover 4; the rear cover 4 is rotatably disposed relative to the input end of the water splash switching component 1; the rear cover 4 has a water inlet channel 41, the distribution direction of the water inlet channel 41 is tangent to the input end of the water splash switching component 1, so that the water flow can drive the water splash switching component 1 to rotate through the water inlet channel 41. After the water flow enters the rear cover 4, it impacts the input end of the water splash switching component 1 along the water inlet channel 41, thereby driving the water splash switching component 1 to rotate, so as to change the position of the guide port 11 and realize the switching of water splashes. Among them, the rear cover 4, the water splash switching component 1, and the water distribution component 2 form the water outlet body. At both ends of the water outlet body in the axial direction, a water inlet component 5 and a water outlet component 3 are respectively provided. The water inlet component 5 and the water outlet component 3 are snapped together. By rotatably connecting the water outlet device on the shower head, the water inlet component 5 and the water outlet component 3 can be used as different water outlet panels of the shower head by flipping the water outlet device, which further enriches the types of water splashes. Furthermore, a water inlet hole 43 connected to the guide port 11 is provided on the rear cover 4. The water inlet hole 43 is used to replenish the water flow entering the water distribution chamber 25. This part of the water flow will be discharged after selecting the corresponding water distribution channel through the guide port 11.

[0032] In some embodiments, the water flow switching assembly 1 includes an active component 12 and a passive component 13; the rear cover 4 has a drive cavity 42, and the water inlet channel 41 communicates with the drive cavity 42; the active component 12 is embedded in the drive cavity 42; the active component 12 and the passive component 13 are connected in a transmission manner, and the guide port 11 is disposed on the passive component 13, which is embedded in the water distribution cavity 25. After the water flows into the drive cavity 42 from the water inlet channel 41, it will push the active wheel to rotate along the tangential direction of the active wheel, and the active wheel will drive the passive wheel to rotate, thereby driving the guide port 11 to rotate, thus changing the position of the guide port 11. Preferably, the water inlet channel 41 is distributed along the tangential direction of the drive cavity 42.

[0033] In some embodiments, the driving member 12 includes a water wheel 121 and a driving gear 122 coaxially arranged; the passive member 13 includes a driven gear 131 and a water distributor 132 coaxially arranged; the water wheel 121 is rotatably disposed in the drive cavity 42, the driving gear 122 meshes with the driven gear 131, and the water distributor 132 is rotatably disposed in the water distribution cavity 25; the guide port 11 is disposed on the side wall of the water distributor 132. The impact force of the water flow on the water wheel 121 is transmitted to the water distributor 132 through the driving gear 122 and the driven gear, thereby changing the position of the guide port 11 and realizing the switching of water spray. Specifically, a first rotating shaft 231 is disposed on the side of the upper water distributor 23 away from the lower water distributor 24, and the driving member 12 is rotatably inserted into the first rotating shaft 231; a second rotating shaft 243 is disposed in the water distribution cavity 25 of the lower water distributor 24, and the passive member 13 is rotatably inserted into the second rotating shaft 243. The water turbine 121 has multiple blades 1211 on its circumferential sidewall, and the distribution direction of the water inlet channel 41 intersects with the distribution direction of the blades 1211, so that the water flowing into the water inlet chamber from the water inlet channel 41 can impact the blades 1211 and thus effectively drive the water turbine 121 to rotate.

[0034] In some embodiments, the water outlet 31 includes a water splash forming hole 311 and a jet hole 312; the inlet end of the water splash forming hole 311 allows water to enter in a direction deviating from the central axis of the water splash forming hole 311, and the outlet end of the water splash forming hole 311 is connected to the jet hole 312; the water passage area of ​​the inlet end of the water splash forming hole 311 is larger than the water passage area of ​​the outlet end of the jet hole 312; all inner walls of the water splash forming hole 311 are smooth walls; the above structure can fully rotate and oscillate along the wall surface of the water splash forming hole 311, and all inner walls of the water splash forming hole 311 are smooth. With a smooth wall surface, the water flow within the water splash forming hole 311 will not be obstructed by planes, corners, etc., thus changing its flow direction and causing disturbance. This allows a stable water vortex to be formed within the water splash forming hole 311, effectively preventing the water from re-aggregating after vibration and breaking, and effectively maintaining the water flow velocity. This effectively enhances the vibration and breaking effect of the water. The jet hole 312 further pressurizes the water flow, effectively improving the particle effect and water pressure of the water after breaking at the water outlet hole 31. In other words, it improves the particle effect of the water splash and increases the water pressure, thereby enhancing the massage effect.

[0035] In one embodiment, the longitudinal section of the water splash forming hole 311 is conical to increase the water flow velocity and achieve a pressurization effect. In other equivalent embodiments, the water splash forming hole 311 can be a combination of a cylindrical inlet and a spherical outlet. Furthermore, the inner wall of the water splash forming hole 311 can also be entirely spherical, or it can be an ellipsoid or other suitable smooth wall structure, or it can be a combination of spherical and arc-shaped smooth surfaces. Those skilled in the art can flexibly choose from these options and are not limited thereto.

[0036] In some embodiments, the water outlet 3 has a water passage 32; the water distribution assembly 2 is connected to the water outlet 31 through the water passage 32; the water passage 32 includes a water flow acceleration section 321 and a water flow receiving section 322, the guide port 11, the water flow receiving section 322 and the water flow acceleration section 321 are connected in sequence, and the water outlet 31 is aligned with the water flow receiving section 322; the water flow area S1 at the inlet end of the water flow acceleration section 321 is smaller than the water flow area S2 at the outlet end of the water flow receiving section 322. Since the water flow area S1 at the inlet end of the water flow acceleration section 321 is smaller than the water flow area S2 at the outlet end of the water flow receiving section 322, the water flow can pass smoothly through the water passage 32, which can reduce the flow velocity loss. Specifically, when the water flow that flows through the second water distribution channel 22 and the drain hole 242 enters the water outlet 31, it needs to pass through the narrower water flow acceleration section 321 first to increase the water flow velocity and play a role in pressurizing the water flow. In other embodiments, the water passage 32 may also take any other suitable shape, such as a uniform straight line or a curved channel, and is not limited thereto.

[0037] In some embodiments, the water inlet area S1 of the water flow acceleration section 321 is greater than 1.2 times the water outlet area S2 of the jet hole 312 and less than 3 times the water outlet area S3 of the jet hole 312, which can produce optimal particulate water in a household water environment.

[0038] In some embodiments, the height of the water splash forming hole 311 is 3 to 5 times the diameter of the outlet end of the jet hole 312. Under the same water pressure and flow conditions in a household water environment, this ensures sufficient water breaking time, improves the water breaking effect, and effectively reduces the remixing of water droplets after breaking. In other embodiments, the dimensions of the outlet hole 31 can be flexibly adjusted according to the usage environment and needs.

[0039] In some embodiments, the water distribution assembly 2 includes a first water distribution channel 21 that is at least partially distributed radially along the water distribution assembly 2 and a second water distribution channel 22 that is at least partially distributed axially along the water distribution assembly 2; the water outlet 31 connects to two intersecting flow channels 26 with the water outlet directions of the two flow channels 26 forming an angle A, 10°≤A≤100°, the first water distribution channel 21 is connected to one of the flow channels 26, and the second water distribution channel 22 is connected to the other flow channel 26. When the guide port 11 connects to the outlet 31 through the first water distribution channel 21, a first water splash with a first outlet angle is formed. When the guide port 11 connects to the outlet 31 through the second water distribution channel 22, a second water splash with a second outlet angle is formed. When the guide port 11 connects to the outlet 31 through both the first and second water distribution channels 21 and two flow channels 26, the two fluids collide within the outlet 31 after passing through the flow channels 26. At this time, the inner wall of the outlet 31 can constrain the fluid particles that disperse after the collision. The outlet angle of the water splash discharged from the outlet 31 is between the individual outlet angles of the two water distribution channels and can change according to the flow rate of the fluid in the two flow channels 26, thereby changing the massage area. The larger the angle between the two flow channels 26, the greater the collision degree of the two water flows, that is, the more dispersed fluid particles are formed. Finally, there will be more dispersed fluid particles around the discharged water flow, and the outline of the discharged water flow will be relatively blurred visually. The smaller the angle between the flow channels 26, the lower the collision degree of the two water streams, the fewer and more concentrated the dispersed fluid particles, and the clearer the water flow outline. However, a small angle also leads to less obvious changes in the fluid discharge trajectory. As described above, the angle between the outlet directions of the flow channels 26 can be limited to balance the fluid discharge pattern and the range of the fluid discharge angle. The preferred range of the angle A between the outlet directions of the two flow channels 26 can be further configured as 65°≤A≤75°.

[0040] In some embodiments, the flow height of the water outlet 31 is S, where 0.5mm ≤ S ≤ 10mm. As described above, if the flow height of the water outlet 31 is too low, it is insufficient to gather a sufficient amount of fluid particles to form regular water droplets with a specific shape. Conversely, if the flow height is too high, it will limit the angle range of the gathered water flow to be discharged outward. Therefore, the flow height of the water outlet 31 is limited to meet the forming effect after the fluid is discharged.

[0041] In some embodiments, the water outlet 31 is shaped like a cuboid, an elliptical cylinder, or a trapezoid. The aspect ratio of the cross-section of the cuboid or trapezoidal water outlet 31 in the water flow direction is (2~8):1, and the width of the water outlet 31 is D, 0.3mm≤D≤2mm. The flow channel 26 introduces two streams of fluid into the water outlet 31 from above the short side, and the fluid is constrained by the long side wall of the water outlet 31. The cavity constructed with the cuboid or trapezoidal shape of the water outlet 31 and the above-mentioned parameter proportions can better constrain the fluid particles that disperse after impact by the long side wall of the water outlet 31, allowing the dispersed fluid particles to immediately converge again after a short-distance splash, thereby gathering the water flow together and discharging it in the form of a columnar water spray, and giving the columnar water spray a clear water column outline. Specifically: when the aspect ratio of the water outlet 31 is less than 2:1, the water column outline is blurred; even when the ratio is (1~1.5):1, only granular water droplets can be formed, and it is impossible to discharge columnar water droplets and create a changing trajectory by controlling the flow intensity. When the aspect ratio of the water outlet 31 is (2.5~4.5):1 and the width D of the water outlet 31 is 0.6mm~1mm, the columnar water droplets generated by the water outlet 31 have a greater rinsing intensity, which is suitable for massage purposes, and the water outlet 31 is not easily clogged by impurities. When the aspect ratio of the water outlet 31 is (2.5~4.5):1 and the width D of the water outlet 31 is 0.6mm~1mm, the water column is more intensely rinsed, suitable for massage purposes, and the water outlet 31 is less likely to be clogged by impurities. When the length-to-width ratio is (4.5~7.5):1 and the width D of the water outlet 31 is 0.3mm~0.6mm, the columnar water droplets produced by the water outlet 31 have a soft feel and are suitable for regular rinsing by setting a large number of water outlets 31 of this size. However, when the length-to-width ratio of the cross-section of the water outlet 31 is greater than 8:1 and the width D of the water outlet 31 is greater than 2mm, the water outlet 31 is too large. Under the flow conditions of domestic water, it is not enough to support setting multiple water outlets 31 of this size to discharge columnar water droplets at the same time, which may cause the formed water droplets to become more granular again.

[0042] In some embodiments, a portion of the water outlets 31 form a first water outlet group 33, and another portion of the water outlets 31 form a second water outlet group 34; the water distribution component 2 includes a first water distribution channel 21 that is at least partially distributed radially along the water distribution component 2 and a second water distribution channel 22 that is at least partially distributed axially along the water distribution component 2; when the guide port 11 is connected to the first water outlet group 33 through the first water distribution channel 21, a first water splash is formed; when the guide port 11 is connected to the second water outlet group 34 through the second water distribution channel 22, a second water splash is formed; when the guide port 11 is simultaneously connected to the first water outlet group 33 and the second water outlet group 34 through the first water distribution channel 21 and the second water distribution channel 22, the first water splash and the second water splash are formed simultaneously.
