Description

A water outlet structure, water-using appliance, and water outlet method Technical Field

[0001] This invention relates to the field of water supply technology, and in particular to a water outlet structure, water-using appliance, and water outlet method. Background Technology

[0002] Existing bathroom products typically change the discharge angle of the water outlet by adjusting the direction of the outlet. Referencing announcements CN1217744C, CN202410859U, CN103170414A, CN104646199B, CN110787919B, CN112058516B, and CN220496656U, the disclosed methods involve using a hydrodynamic impeller to drive the nozzle rotation or change the spray angle. This type of solution has a complex architecture, requiring multiple stages of transmission to achieve a suitable rate of change in the fluid discharge angle. Furthermore, each nozzle unit needs to be independently arranged. If a large number of nozzles are required (e.g., a typical showerhead has around 100 nozzles), each nozzle must be installed individually onto the panel, significantly complicating nozzle installation efficiency and hindering the integration of individual nozzle units with other structural elements.

[0003] In addition, patent documents CN2806909Y, CN201026468Y, CN201223835Y, CN201949936U, CN202113962U, CN103962253B and CN111263665B disclose valves that adjust the flow rate of a single or multiple water channels by changing the flow area of ​​the water. Technical issues

[0047] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0048] Referring to Figures 1 to 10, the present invention provides a water outlet structure having two flow channels 1 configured to intersect in the water outlet direction; a flow regulating device 2 configured to regulate the flow rate of at least one flow channel 1; and a cavity 3 provided in the water outlet direction of the flow channel 1, the cavity 3 being configured to cause the water flow after intersection to deviate towards the flow channel with stronger flow rate, where stronger flow rate refers to a larger volume of water flowing through a unit area per unit time.

[0049] Working Principle: As shown in Figure 1, when two water streams collide, the fluid particles after the collision are scattered and dispersed to both sides of the water flow direction, forming irregular particle water splashes. To address this, as shown in Figures 2 and 3, a cavity 3 is added to constrain the dispersed fluid particles, causing them to re-converge in a specific direction after being constrained by the inner wall of the cavity 3, forming regular water splashes of a specific shape. Simultaneously, if one of the colliding water streams is stronger than the other (i.e., has a larger flow rate), the discharge trajectory of the fluid after the collision will tend to follow the original discharge trajectory of the stronger water stream, as shown in Figure 4. Here, the thickness of the arrows representing the two converging first fluid streams 8 indicates their flow strength, with the thicker first fluid stream 8 being stronger than the thinner one. Therefore, by adjusting the strength of at least one of the water streams, the fluid discharge trajectory can be changed, meaning the intersecting water streams deviate towards the direction of the stronger flow channel 1.

[0050] It is worth noting that, as shown in Figures 2 and 5, when the flow channel 1 introduces two streams of first fluid 8 into the cavity 3 from above the short side, and the long side wall of the cavity 3 constrains the dispersed fluid particles, the dispersed fluid particles splash over a short distance, allowing the converged second fluid 9 to be discharged in the form of a columnar water droplet. Simultaneously, by adjusting the water flow intensity in at least one flow channel 1, the discharge trajectory of the columnar water droplet can be changed. This change in the discharge trajectory can be represented by a change in the angle of the water column relative to the axis of the discharge outlet.

[0051] As shown in Figures 3 and 6, when the flow channel 1 introduces two streams of first fluid 8 into the cavity 3 from above the long side, and the short side wall of the cavity 3 constrains the dispersed fluid particles, the dispersed fluid particles splash a long distance, allowing the converged second fluid 9 to be discharged in the form of sheet-like water droplets. Simultaneously, by adjusting the water flow intensity in at least one flow channel 1, the discharge trajectory of the sheet-like water droplets can be changed. This change in the discharge trajectory can be represented by an angular change in the overall water sheet relative to the axis of the discharge port.

[0052] It is worth noting that a flow regulating device 2 is provided upstream of at least one flow channel 1, thereby enabling the flow intensity in at least one flow channel 1 to be adjusted remotely.

[0053] In some embodiments, the flow regulating device 2 is located between the water supply source and the flow channel 1 of the outlet structure. The portions of the two flow channels 1 between the flow regulating device 2 and the cavity 3 are isolated from each other, and the flow rate of the water source entering at least one flow channel 1 is controlled by the flow regulating device 2. This arrangement ensures the independence of the water flow rates of the two flow channels 1, thereby ensuring that the flow rate of at least one flow channel 1 can be independently increased or decreased, allowing the water flow that is finally discharged outward after passing through the cavity 3 to produce a change in trajectory. Otherwise, if the two flow channels 1 do not have relative independence, the water flow rate can only be increased or decreased synchronously, and the trajectory of the water flow that is finally discharged outward will not change.

[0054] In this preferred embodiment, a flow regulating device 2 is provided at the upstream of each of the two flow channels 1. The flow regulating device 2 is configured to control the flow of the two flow channels 1 in opposite proportions. Even if the flow rate of one flow channel 1 is increased, the flow rate of the other flow channel 1 is decreased. This allows the water flow that is finally discharged outward after passing through the cavity 3 to produce a more significant trajectory change.

[0055] It is worth noting that the two streams of water can collide either above cavity 3 or inside cavity 3.

[0056] It is worth noting that, as shown in Figures 5 to 8, the cavity 3 is preferably in the shape of a cuboid, an ellipse, or a trapezoid. Specifically, the aspect ratio of the cross-section of the cuboid or trapezoidal cavity 3 in the water-passing direction is 2 to 3:1. Preferably, the width of the cavity 3 is D, where 0.3 mm ≤ D ≤ 2 mm.

[0057] The ratio of the major axis to the minor axis of the cross-section of the elliptical cylindrical cavity 3 in the water-passing direction is 2~3:1. Preferably, the minor axis of the cavity 3 is D, where 0.3mm≤D≤2mm.

[0058] It should be noted that the flow regulating device 2 can be a valve commonly used in the art to regulate the flow of a single or multiple water channels by changing the water flow area, or it can be an external water pump that directly regulates the flow by changing the pump power.

[0059] Further, referring to Figure 9, the water outlet directions of flow channels 1 form an angle A, where 10° ≤ A ≤ 100°. If the angle between flow channels 1 is larger, the collision between the two water streams is greater, resulting in more dispersed and scattered fluid particles. Consequently, the discharged water stream will have more dispersed fluid particles around it, making the visual outline of the discharged water stream appear blurry. If the angle between flow channels 1 is smaller, the collision between the two water streams is lower, resulting in fewer and more concentrated dispersed fluid particles, and a clearer water stream outline. However, a smaller angle leads to less noticeable changes in the fluid discharge trajectory. As described above, by limiting the angle between the water outlet directions of flow channels 1, both the fluid discharge pattern and the range of discharge angles can be considered. The preferred range for the angle A of the water outlet direction of flow channels 1 can be further configured as 65° ≤ A ≤ 75°.

[0060] It should be noted that, referring to Figure 9, with the central axis of cavity 3 as the reference, the two flow channels 1 can be symmetrically arranged on both sides of the central axis of cavity 3. For example, the water outlet direction of one flow channel 1 forms an angle B with the central axis of cavity 3, and the water outlet direction of the other flow channel 1 forms an angle C with the central axis of cavity 3. Angle B is equal to angle C, and angle B plus angle C equals angle A. Alternatively, the two flow channels 1 can be asymmetrically arranged on both sides of the central axis of cavity 3. For example, the water outlet direction of one flow channel 1 forms an angle B with the central axis of cavity 3, and the water outlet direction of the other flow channel 1 forms an angle C with the central axis of cavity 3. Angle B is not equal to angle C, and angle B plus angle C equals angle A.

[0061] Referring to Figures 5 and 6, further, the inlet flow area to the outlet flow area of ​​flow channel 1 is equal or the inlet flow area to the outlet flow area of ​​flow channel 1 gradually decreases.

[0062] As can be seen from the above description, if the inlet flow area to the outlet flow area of ​​channel 1 is equal, it can ensure the relative stability when the two streams collide. If the inlet flow area to the outlet flow area of ​​channel 1 gradually decreases, channel 1 will have the effect of increasing water pressure and can enhance the impact effect when the two streams collide.

[0063] Furthermore, the ratio of the inlet flow area to the outlet flow area of ​​flow channel 1 is X, where 1 ≤ X ≤ 2.

[0064] As described above, the inlet flow area of ​​flow channel 1 is limited to no more than twice the outlet flow area of ​​flow channel 1, in order to avoid generating more fluid particles when the two streams of water collide, thereby ensuring that water splashes with clear water flow outlines can be effectively formed.

[0065] Please refer to Figure 9. Further, the flow length of cavity 3 is S, where 0.5mm ≤ S ≤ 2mm.

[0066] As can be seen from the above description, if the flow length of cavity 3 is too short, it is not enough to gather a sufficient amount of fluid particles to form regular water splashes with a specific shape. Conversely, if the flow length is too long, it will limit the angle range of the water flow after gathering and discharge. Therefore, the flow length of cavity 3 is limited to meet the forming effect after the fluid is discharged.

[0067] Furthermore, the fluid flow area of ​​cavity 3 gradually decreases along its own water outlet direction.

[0068] As described above, when the fluid flow area of ​​the cavity 3 near the flow channel 1 is greater than the fluid flow area at the outlet of the cavity 3, the flow area of ​​the cavity 3 gradually narrows, which can have a pressurizing effect, and the outline of the water splashes discharged after passing through the cavity 3 will be clearer; conversely, if the fluid flow area of ​​the cavity 3 near the flow channel 1 is smaller than the fluid flow area at the outlet of the cavity 3, the flow area of ​​the cavity 3 gradually expands, and the outline of the water splashes discharged after passing through the cavity 3 will become blurred.

[0069] Please refer to Figures 12 and 13. A baffle 4 is provided on the outside of the cavity 3. The baffle 4 is located on the extension trajectory of the flow channel 1 toward the cavity 3. The baffle 4 is configured to disperse the water flow discharged from the cavity 3 into particles.

[0070] As can be seen from the above description, when the angle of the columnar water flow discharged by the flow regulating device 2 impacts the inner wall of the baffle 4, the baffle 4 will disperse the water flow, causing the water flow to form sheet-like water splashes, and the overall outline of the water splashes is trapezoidal or fan-shaped.

[0071] Referring to Figure 13, in some embodiments, the water-facing surface of the baffle 4 that is impacted by the water flow is a concave arc-shaped surface. The arc-shaped surface can reduce the splashing of fluid particles after the water flow impacts the baffle 4, thereby ensuring the water splash formation effect.

[0072] It is worth noting that the shape of the baffle 4 can be rectangular, semi-circular, trapezoidal, or hexagonal. The trapezoid is an isosceles trapezoid, with its longer side close to the cavity 3, and the shorter side of the trapezoid is rounded at the junction with the two sides. The hexagon is formed by separating from the longer side at each of the two sides of the isosceles trapezoid, creating two straight sides. This structure produces minimal particle splashing and provides the clearest water flow profile.

[0073] Please refer to Figure 14. A water-blocking groove 5 is provided in the water outlet direction of the cavity 3. The water-blocking groove 5 is connected to the cavity 3. The water-blocking groove 5 is located on the extension trajectory of the flow channel 1 towards the cavity 3. The water-blocking groove 5 is configured to make the water flow discharged from the cavity 3 discrete into particles.

[0074] As can be seen from the above description, when the discharge angle of the columnar water flow, adjusted by the flow regulating device 2, impacts the inner wall of the water-blocking channel 5, the water-blocking channel 5 will disperse the water flow, causing the water flow to form sheet-like water splashes, and the overall outline of the water splashes is trapezoidal or fan-shaped.

[0075] In some embodiments, the water-facing surface of the water-retaining groove 5 that is impacted by the water flow is a concave arc-shaped surface. The arc-shaped surface can reduce the splashing of fluid particles after the water flow impacts the water-retaining groove 5.

[0076] In the above schemes, either the baffle 4 or the water-blocking trough 5 can be set on the extension trajectory of any one flow channel 1, or they can be set on the extension trajectory of two flow channels 1 at the same time.

[0077] A water discharge method wherein at least two first fluids 8 with different flow angles converge and are constrained to form a second fluid 9 for discharge; the flow rate of at least one of the first fluids 8 is adjusted to change the discharge trajectory of the second fluid 9.

[0078] Furthermore, the constraint has at least two different directions: a first directional constraint and a second directional constraint.

[0079] Furthermore, at least two first fluids with different flow directions form an angle, and the emission trajectory varies within the diagonal range of the angle.

[0080] Furthermore, at least two first fluids with different flow directions form an angle A, where 10°≤A≤100°.

[0081] Furthermore, at least two first fluids 8 with different flow angles converge to form a third fluid, and the third fluid is constrained to form a second fluid 9 before being discharged.

[0082] A water discharge method comprising at least two first fluids 8 with different flow angles converging and being constrained to form a second fluid 9 for discharge;

[0083] The flow rate of at least one stream of the first fluid 8 is adjusted so that the discharge trajectory of the second fluid 9 oscillates.

[0084] Example 1

[0085] This embodiment is applicable to bathroom products with a single water flow, such as toilet nozzles, which can achieve variable-angle posterior wash jet discharge without setting up additional complex structures.

[0086] Referring to Figure 15, a toilet nozzle has a water inlet path that is connected to two flow channels 1, and a flow regulating device 2 is provided upstream of the water inlet path. The flow regulating device 2 can be an electric water pump built into the toilet itself.

[0087] Example 2

[0088] This embodiment is applicable to the simultaneous angle adjustment of multiple water streams.

[0089] Please refer to Figure 10. A water outlet device includes a first water outlet plate 6, a water distribution plate 7, and a flow regulating device 2.

[0090] The first water outlet plate 6 is provided with multiple discharge chambers, and the water distribution plate 7 is provided with partitions 71 and water passage holes 72 equal in number to the number of discharge chambers, as well as at least one water passage hole 73 for conveying fluid to the cavity between the water distribution plate 7 and the first water outlet plate 6. The partitions 71 and water passage holes 72 are arranged adjacent to each other, and the partitions 71 are located on the drainage surface of the water distribution plate 7.

[0091] The water distribution plate 7 is assembled on the water-facing surface of the first water outlet plate 6. The partition plate 71 is embedded in the discharge chamber to separate the discharge chamber, forming two flow channels 1 and a cavity 3 in the water outlet direction of the flow channels 1. The two flow channels 1 and the cavity 3 are arranged in a Y-shape. The water distribution plate 7 divides the water flow into two water paths. The water passage hole 72 guides the water flow through one of the flow channels 1 and directly into the cavity 3 of all discharge chambers. The water passage hole 73 guides the water flow to pass through the water distribution plate 7 and then enter the cavity between the water distribution plate 7 and the first water outlet plate 6. Then, from this cavity, it enters the cavity 3 of all discharge chambers through the other flow channel 1. In this way, the two water paths can independently supply water to the two flow channels 1 of each discharge chamber.

[0092] The flow regulating device 2, located upstream of the two flow channels 1, is used to regulate the flow of at least one of the water channels after the diversion, so that the two water streams collide with each other and are rectified by the cavity 3 to produce a specific angle for discharge to the outside.

[0093] Referring to Figure 11, in another optional embodiment, based on the structure of the previous optional embodiment of this embodiment, the water outlet device adds an independent water outlet cavity 10 and a second water outlet plate 11 at the center of the first water outlet plate 6. The second water outlet plate 11 is sealed at the water outlet end of the water outlet cavity 10. The second water outlet plate 11 can be fixedly installed on the water outlet cavity 10 by means of a snap-fit, thread or other connection structure. Alternatively, the second water outlet plate 11 can be configured as a double-sided water outlet panel with a spherical edge, and the water outlet end of the water outlet cavity 10 can be configured as having an inner wall that is complementary to the spherical edge, so that the second water outlet plate 11 can be flipped and installed on the water outlet end of the water outlet cavity 10. The double-sided water outlet panel of the second water outlet plate 11 can be configured to produce the same water splash or to produce different water splashes on each side.

[0094] In this embodiment, the flow regulating device 2 is configured to have three fluid outlets that supply water to different water paths. Specifically: the first fluid outlet is used to independently supply water to the outlet chamber 10; the second and third fluid outlets can supply water to the two flow channels 1 of each discharge chamber on the first outlet plate, respectively. Unlike the previous embodiment, the water distribution plate 7 in this embodiment does not need to be provided with water passage holes 73; the second fluid outlet is configured to supply water to the water-facing surface of the water distribution plate 7; and the third fluid outlet is configured to directly supply water to the cavity between the water distribution plate 7 and the first outlet plate 6.

[0095] In this embodiment, the flow regulating device 2 can switch between allowing the first outlet plate 6 to generate a discharge flow independently and allowing the second outlet plate 11 to generate a discharge flow independently. This switching can be a gradual switching or a shifting switching, depending on the specific structure of the flow regulating device 2. Similarly, as described in the previous optional embodiment, the flow regulating device 2 can control the flow rate / intensity of the two flow channels 1 output to the discharge chamber of the first outlet plate 6, causing a change in the trajectory of the water discharged from the first outlet plate 6; and the flow regulating device 2 can also control the flow rate of the water discharged from the second outlet plate 11 to change.

[0096] Example 3

[0097] This embodiment applies the water outlet device to a pull-out faucet, based on Embodiment 2, and is generally used with kitchen faucets.

[0098] Referring to Figures 16 and 17, a pull-out faucet includes a housing and a water outlet device. The water outlet of the housing is fitted with a first water outlet plate 6. The first water outlet plate 6 is provided with multiple discharge chambers. The water distribution plate 7 is provided with partitions 71 and water passage holes 72, which are equal in number to the number of discharge chambers, as well as at least one water passage hole 73 for conveying fluid to the cavity between the water distribution plate 7 and the first water outlet plate 6. The partitions 71 and the water passage holes 72 are arranged adjacent to each other, and the partitions 71 are located on the drainage surface of the water distribution plate 7.

[0099] The water distribution plate 7 is assembled on the water-facing surface of the first water outlet plate 6. The partition plate 71 is embedded in the discharge chamber to separate the discharge chamber, forming two flow channels 1 and a cavity 3 on the water outlet side of the flow channel 1. The two flow channels 1 and the cavity 3 are arranged in a Y-shape. The water distribution plate 7 divides the water flow into two water paths. The water passage hole 72 guides the water flow through one of the flow channels 1 and directly into the cavity 3 of all discharge chambers. The water passage hole 73 guides the water flow to pass through the water distribution plate 7 and then into the cavity between the water distribution plate 7 and the first water outlet plate 6. Then, from this cavity, it enters the cavity 3 of all discharge chambers through the other flow channel 1. In this way, the two water paths can independently supply water to the two flow channels 1 of each discharge chamber.

[0100] It also includes a flow regulating device 2, which has a valve core located inside the housing cavity and a push button slidably disposed outside the housing. The push button is drivenly connected to the adjusting end of the valve core. By controlling the opening of the valve core with the push button, the flow regulating device 2 can regulate the flow rate of any one of the water channels after diversion, so that the two water streams collide with each other and are rectified by the cavity 3 to be discharged to the outside at a specific angle.

[0101] In another alternative embodiment, a second water outlet plate 11 is nested inside the first water outlet plate 6. The water-facing side of the second water outlet plate 11 is independently connected to the valve core, so that whether the second water outlet plate 11 is irrigated and the amount of water flow can be independently controlled by the valve core.

[0102] Please refer to Figure 18. Another type of pull-out faucet, different from the pull-out faucets shown in Figures 16 and 17, has a flow regulating device 2 with a knob rotatably mounted outside the housing. The knob is connected to the regulating end of the valve core, thereby driving the valve core to control the water flow variation mode of the pull-out faucet.

[0103] Example 4

[0104] This embodiment applies the water outlet device to a shower head, based on embodiment two, and is generally used in conjunction with a shower in a bathroom.

[0105] Please refer to Figures 11 and 19. A shower head includes a shower head, a handle, and a water outlet device. The water outlet of the shower head is embedded with a first water outlet plate 6. The first water outlet plate 6 is provided with multiple discharge chambers. The water distribution plate 7 is provided with partitions 71 and water passage holes 72 in the same number as the discharge chambers. The partitions 71 and water passage holes 72 are arranged adjacent to each other. The partitions 71 are located on the drainage surface of the water distribution plate 7.

[0106] The water distribution plate 7 is assembled on the water-facing surface of the first water outlet plate 6. The partition plate 71 is embedded in the discharge chamber to separate the discharge chamber, forming two flow channels 1 and a cavity 3 on the water outlet side of the flow channel 1. The two flow channels 1 and the cavity 3 are arranged in a Y-shape. The water distribution plate 7 divides the water flow into two water paths. The water passage 72 guides the water flow through one of the flow channels 1 into the cavity 3 of all discharge chambers. The cavity between the water distribution plate 7 and the first water outlet plate 6 guides the water flow through the other flow channel 1 into the cavity 3 of all discharge chambers. In this way, the two water paths can independently supply water to the two flow channels 1 of each discharge chamber.

[0107] It also includes a flow regulating device 2, which has a valve core located inside the handle cavity and an operating part located outside the handle. The operating part can be configured as a button, push knob, or knob, etc. The operating part is connected to the regulating end of the valve core. The valve core is configured to independently supply water to the water-facing surface of the water-dividing plate 7 and the cavity between the water-dividing plate 7 and the first water outlet plate 6. In this way, by controlling the opening of the valve core through the operating part, the flow regulating device 2 can regulate the flow of any one of the water paths after diversion, so that the two water streams collide with each other and are rectified by the cavity 3 to produce a specific angle for discharge to the outside.

[0108] In another alternative embodiment, a second water outlet plate 11 is nested inside the first water outlet plate 6. The water-facing side of the second water outlet plate 11 is independently connected to the valve core, so that whether the second water outlet plate 11 is irrigated and the amount of water flow can be independently controlled by the valve core.

[0109] Example 5

[0110] This embodiment applies the water outlet device to a sanitary spray gun, based on embodiment two. It is generally used with a shower in a bathroom or a toilet in a toilet, and can also be used for car washing.

[0111] Please refer to Figures 20 and 21. A sanitary sprinkler head includes a housing and a water outlet device. The water outlet of the housing is embedded with a first water outlet plate 6. The first water outlet plate 6 is provided with multiple discharge chambers. The water distribution plate 7 is provided with partitions 71 and water passage holes 72 in the same number as the discharge chambers. The partitions 71 and water passage holes 72 are arranged adjacent to each other. The partitions 71 are located on the drainage surface of the water distribution plate 7.

[0112] The water distribution plate 7 is assembled on the water-facing surface of the first water outlet plate 6. The partition plate 71 is embedded in the discharge chamber to separate the discharge chamber, forming two flow channels 1 and a cavity 3 on the water outlet side of the flow channel 1. The two flow channels 1 and the cavity 3 are arranged in a Y-shape. The water distribution plate 7 divides the water flow into two water paths. The water passage 72 guides the water flow through one of the flow channels 1 into the cavity 3 of all discharge chambers. The cavity between the water distribution plate 7 and the first water outlet plate 6 guides the water flow through the other flow channel 1 into the cavity 3 of all discharge chambers. In this way, the two water paths can independently supply water to the two flow channels 1 of each discharge chamber.

[0113] It also includes a flow regulating device 2 for regulating the flow rate of at least one water path after diversion; the flow regulating device 2 has a valve core located in the inner cavity of the housing, and the flow regulating device 2 has an operating part slidably disposed outside the housing, the operating part being drivenly connected to the regulating end of the valve core.

[0114] In another alternative embodiment, a second water outlet plate 11 is nested inside the first water outlet plate 6. The water-facing side of the second water outlet plate 11 is independently connected to the valve core, so that whether the second water outlet plate 11 is irrigated and the amount of water flow can be independently controlled by the valve core.

[0115] Example 6

[0116] The difference between this embodiment and Embodiment 5 is that the housing of the sanitary spray gun has two discharge ports, and the discharge directions of the two discharge ports are at an angle of approximately 90 degrees.

[0117] Please refer to Figure 22. A nozzle includes a housing and a water outlet device. The housing has two water outlets. A first water outlet plate 6 and a second water outlet plate 11 are respectively installed at one water outlet. The flow regulating device 2 controls the first water outlet plate 6 or the second water outlet plate 11 to discharge water.

[0118] Example 7

[0119] This embodiment applies the water outlet device to a top-spray shower head, based on embodiment two. It is generally connected to the shower head in the bathroom and fixed to the wall for use.

[0120] Please refer to Figure 23. A top-spray type shower head includes a shower unit, a water pipe, and a shower head. The shower unit is equipped with a flow regulating device 2. The shower unit is fixed to the wall and connected to a water source. It is connected to the shower head through a water pipe fixed to the wall, thereby delivering water to the shower head. The shower head includes the first water outlet plate 6, water distribution plate 7, and other structures as described in Embodiment 2.

[0121] The strength of the two first fluids 8 entering the shower head is remotely adjusted by the flow regulating device 2, as shown in Figure 23. After being constrained by the cavity 3 in the first water outlet plate 6, the second fluid 9 discharged outward can produce a change in the shower angle (the solid water flow trajectory and the dashed water flow trajectory in the figure represent the different shower angles formed by the second fluid 9 under two different adjustment states). Compared with the existing overhead shower head, which requires the user to raise their arm or even stand on another object to raise their arm in order to adjust the shower angle of the high shower head, this embodiment allows people of different heights to easily adjust the shower angle by operating the shower head, which significantly improves the user experience of the overhead shower head.

[0122] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
