[0035] In order to explain the technical content, the purpose and the effect of the utility model in detail, the following will be explained in combination with the embodiment and the drawings.

[0036] Please refer to Figures 1 to 6 , the utility model of a structure, including water outlet plate 1 and water distribution plate 2; water distribution plate 2 is arranged on the water surface of water outlet plate 1, and water outlet plate 1 is provided with water passing cavity 11; water distribution plate 2 is provided with protruding block 21 that is inserted into water passing cavity 11; protruding block 21 and the side wall of water passing cavity 11 are enclosed to form two flow channels 3 of water outlet direction intersection.

[0037] Working principle: water passing cavity 11 is arranged on water outlet plate 1, and protruding block 21 that can be inserted into water passing cavity 11 is additionally arranged on water distribution plate 2, and the side wall of water passing cavity 11 is enclosed to form two flow channels 3 of water outlet direction intersection, so that only by adjusting the flow in at least one flow channel 3, the degree of collision of two intersecting water flows is changed, thereby changing the shape of water spray discharged by water outlet plate 1.

[0038] Please refer to Figure 3 and Figure 4 , further, water distribution hole 4 that is communicated with one flow channel 3 is opened near protruding block 21, through hole 22 is arranged on water distribution plate 2, or through hole 22 is arranged on the lateral direction of the cavity enclosed by water outlet plate and water distribution plate, and through hole 22 is communicated with another flow channel 3.

[0039] From the above description, when water body passes through water distribution plate 2, the water body will flow into different flow channels 3 through water distribution hole 4 and through hole 22 respectively.

[0040] Please refer to Figure 5 and Figure 6As shown, further, a baffle 12 is provided around the water passage cavity 11 on the water-facing surface of the water outlet plate 1, and the through hole 22 faces the water-facing surface of the water outlet plate 1. A water passage 5 is provided on the baffle 12, and the water passage 5 is connected to the flow channel 3.

[0041] As described above, during the process of water being divided by the water dividing plate 2, part of the water enters the flow channel 3 through the water dividing hole 4 on the water dividing plate 2, and the other part of the water flows into the water-facing surface of the water outlet plate 1 through the through hole 22, and then enters another flow channel 3 through the water outlet 5 of the enclosure 12.

[0042] Please refer to Figures 7 to 9 As shown, further, the water passage 11 is connected to the cavity 6 below the protrusion 21, and the two flow channels 3 and the cavity 6 are arranged in a Y-shape.

[0043] As described above, when two water flows collide, if one flow 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 flow. Figure 7 As shown, the thickness of the arrows representing the two converging first fluids 7 indicates their flow strength, with the thicker first fluid 7 being stronger than the thinner one. Therefore, by adjusting the strength of at least one of the flow streams, the fluid discharge trajectory can be changed, meaning the intersecting streams deviate towards the direction of the stronger flow channel 3. Furthermore, considering that when two flow streams collide, the splashing direction of the fluid particles after the collision is mainly irregularly scattered to both sides of the flow direction, a cavity 6 is provided in the outlet direction of the flow channel 3. This cavity 6 restricts the splashing of fluid particles and re-converges the second fluid 8 formed by the collision of the fluid particles and the first fluid 7, ensuring the shape of the outflowing second fluid 8.

[0044] It is worth noting that, such as Figure 8 As shown, when the flow channel 3 introduces two streams of fluid into the cavity 6 from above the short side, and the long side wall of the cavity 6 constrains the dispersed fluid particles, the dispersed fluid particles splash over a short distance, allowing the converged fluid to be discharged in the form of a columnar water droplet. Simultaneously, by adjusting the water flow intensity in at least one flow channel 3, the discharge trajectory of the columnar water droplet can be varied. This variation in the discharge trajectory can be represented by a change in the angle of the entire water column relative to the axis of the discharge outlet.

[0045] like Figure 9As shown, when the flow channels 3 introduce two streams of fluid from above the long sides of the cavity 6 into the cavity 6, and the dispersed fluid particles are constrained by the short side walls of the cavity 6, the dispersed fluid particles splash a long distance, so that the converged fluid can be discharged in the form of a sheet of water. At the same time, by adjusting the flow intensity in at least one of the flow channels 3, the discharge trajectory of the sheet of water can be changed, which can present an angle change of the whole sheet of water relative to the axis of the discharge port.

[0046] It is worth noting that the cavity 6 is preferably in the shape of a rectangular prism or an elliptical cylinder or a trapezoidal body. Specifically, the cavity 6 in the shape of a rectangular prism or a trapezoidal body has a length-to-width ratio of 2-3:1 in the direction of water flow. Preferably, the width of the cavity 6 is D, and 0.3mm≤D≤2mm.

[0047] The cavity 6 in the shape of an elliptical cylinder has a major-to-minor axis ratio of 2-3:1 in the direction of water flow. Preferably, the minor axis of the cavity 6 is D, and 0.3mm≤D≤2mm.

[0048] The protrusion 21 is preferably in the shape of a wedge, which not only facilitates the protrusion 21 to extend into the water flow cavity 11, but also ensures the sealing between the protrusion 21 and the water flow cavity 11, ensuring that only the water inlet 5 and the water distribution hole 4 allow water to flow into the flow channel 3.

[0049] Please refer to Figure 2 As shown, further, the water discharge direction of the flow channel 3 forms an angle A, and 10°≤A≤100°. The greater the angle between the flow channels 3, the greater the degree of collision of the two water streams, i.e., the more and more dispersed fluid particles, and finally the water flow around the discharged water flow will have more dispersed fluid particles, and the water flow profile will be visually blurred. The smaller the angle between the flow channels 3, the lower the degree of collision of the two water streams, i.e., the fewer and more concentrated dispersed fluid particles, and the water flow profile is relatively clear, but the small angle brings the problem that the change of the fluid discharge trajectory is not obvious. As described above, by limiting the angle between the water discharge directions of the flow channels 3, the discharge form effect of the fluid and the angle range of the fluid discharge can be considered, and the range of the water discharge direction angle A of the flow channels 3 can be further configured as 65°≤A≤75°.

[0050] It needs to be additionally explained that please refer to Figure 2As shown, two flow channels 3 can be symmetrically arranged on both sides of the central axis of the cavity 6, for example, one flow channel 3 has an angle B with the central axis of the cavity 6, and the other flow channel 3 has an angle C with the central axis of the cavity 6, the angle B is equal to the angle C, and the angle B plus the angle C is equal to the angle A. Two flow channels 3 can also be asymmetrically arranged on both sides of the central axis of the cavity 6, for example, one flow channel 3 has an angle B with the central axis of the cavity 6, and the other flow channel 3 has an angle C with the central axis of the cavity 6, the angle B is not equal to the angle C, and the angle B plus the angle C is equal to the angle A.

[0051] Please refer to Figure 7 and Figure 8 As shown, the inlet flow area of the flow channel 3 is equal to the outlet flow area,

[0052] or the inlet flow area of the flow channel 3 gradually decreases to the outlet flow area.

[0053] As described above, if the inlet flow area of the flow channel 3 is equal to the outlet flow area, it can ensure the relative stability when the two water flows collide, and if the inlet flow area of the flow channel 3 gradually decreases to the outlet flow area, the flow channel 3 has the effect of enhancing water pressure, which can enhance the impact effect when the two water flows collide.

[0054] Further, the ratio of the inlet flow area to the outlet flow area of the flow channel 3 is X, 1≤X≤2.

[0055] As described above, the inlet flow area of the flow channel 3 is limited to not more than twice the outlet flow area of the flow channel 3, so as to avoid generating too many fluid particles when the two water flows collide, thereby ensuring that a water flow with clear water flow profile can be effectively formed.

[0056] In other embodiments, the water outlet structure can not only be applied to shower products with multiple water outlets, but also can be applied to bathroom products with single water outlet, such as toilet sprayers, which can realize variable-angle hip washing jet discharge without setting additional complex structures.

[0057] Please refer to Figure 10 As shown, a toilet sprayer, a water receiving surface of a water outlet plate 1 is provided with a fence 12, a protruding block 21 of a water passing cavity 11 extending into the fence 12 is arranged on a water distribution plate 2, two flow channels 3 with intersecting water outlet directions are formed by the side wall of the water passing cavity 11 and the protruding block 21, and the water outlet direction of the flow channel 3 is provided with a cavity 6; the water distribution plate 2 divides the water body into two water flow channels, and respectively communicates with the two flow channels 3. The flow of the flow channel 3 is adjusted by the electric water pump of the toilet itself.

[0058] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
