DETAILED DESCRIPTION

[0051] Please refer to Figures 1 to 12 The water outlet device comprises a shell part 1 and a water outlet assembly 2. The shell part 1 comprises an upper shell 11 and a lower shell 12. The upper shell 11 is provided with a connector 111. The lower shell 12 is fixedly mounted on the upper shell 11. An intermediate cavity 13 connected to the connector is formed between the upper shell 11 and the lower shell 12. The water outlet assembly 2 comprises an ejector 21 and a water outlet 22 arranged along the water outlet flow direction.

In the specific structure, the ejector 21 is provided with a through hole, and a rib 212 is convexly provided on the inner wall of the through hole. By providing the rib 212, the through hole constitutes the above-mentioned ejection hole, and the ejection hole is a plum blossom-shaped structure. The water outlet 22 is provided with a shielding portion 221 and a water outlet hole 222 which penetrates the shielding portion 221, and the opening of the water outlet hole 222 expands outwardly along the water outlet flow direction; the water flow ejected by the jet hole 211 is divided into an impact part and a straight-rushing part, the impact part impacts the shielding portion 221 and flows out along the edge (not the periphery) of the water outlet hole 222 to form a water curtain, and the straight-rushing part directly rushes through the water outlet hole 222 and is ejected to form straight-rushing water, so that the water flow flowing out of the water outlet hole 222 includes a straight-rushing water flow 31 and a semi-enclosed water curtain 32 which semi-encloses the straight-rushing water flow 31.

[0053] In this specific embodiment: the opening of the water outlet 222 is a tapered structure 223 with a larger bottom and a smaller top. In the specific structure, the water outlet 222 is provided with an upper section and a lower section along the water flow direction. The upper section is formed by the upper end of the water outlet 222 extending downward, and the lower section is formed by the lower periphery of the upper section expanding downward and extending outward, and the lower section constitutes the above-mentioned tapered structure 223. The periphery of the upper end of the water outlet 222 includes a V-shaped section 224, two curved sections 225 axially symmetrically arranged on both sides of the V-shaped section, and an arc section 226. One end of the two curved sections 225 is respectively connected to the two ends of the V-shaped section 224, and the two curved sections 225 and the V-shaped section 224 cooperate to form a W-shaped structure. The two ends of the arc section 226 are respectively connected to the other ends of the two curved sections 225. The opening of the arc section 226 is arranged to face away from the top angle of the V-shaped section 224. The curved section is a circular arc section, and the center angle of the circular arc section is greater than 180 degrees. Wherein: the area enclosed by the V-shaped section 224 is provided with a central area 224', and the other areas in the water outlet 222 except the central area 224' constitute the remaining areas 225', and the remaining areas 225' semi-enclose the central area 224', or, the area enclosed by the curved section 225 is provided with the remaining areas 225', and the other areas in the water outlet 222 except the remaining areas 225' constitute the central area 224', and similarly, the remaining areas 225' semi-enclose the central area 224'. The straight-forward portion corresponds to the central area 224', and the impact portion impacts the shielding portion 221 and flows out along part or all of the two curved sections 225 or can be disconnected, or / and, part or all of the arc section 226 or can be disconnected, thereby forming a fan-shaped semi-enclosed water curtain, and the semi-enclosed water curtain 32 semi-encloses the straight-forward water flow 31. The water curtain 32 is formed into a semi-enclosed water curtain 32 through the above structure. The semi-enclosed water curtain 32 is not closed in an annular shape or is disconnected in the middle. When passing through the conical structure 223, according to the wall attachment effect principle, the water flow finally shoots out fan-shaped water sprays that expand outward along the outer wall of the water outlet. Since the fan-shaped water sprays expand outward, after the water sprays expand outward for a certain distance, the fan-shaped water sprays break to form granular water sprays. The periphery of the upper port of the water outlet is connected by a plurality of connecting lines, and the connection of each connecting line is smoothly transitioned.

[0054] In this specific embodiment: the ejector 21 is provided with a jet hole 211, and the water outlet 22 is provided with a plurality of water outlet holes 222. For example, three water outlet holes 222 are provided in the figure, but it is not limited thereto. Four, five, six, etc. may also be provided as needed. One jet hole corresponds to a plurality of water outlet holes, and the plurality of water outlet holes are arranged in a circular array, and the axis of the circular array coincides with the axis of the jet hole. The top angle of the V-shaped section 224 of the water outlet 222 faces the axis of the circular array. The water outlet 222 has a central area covered by the top projection of the jet hole 211 and the remaining area outside the top projection, and the top projection of the jet hole 211 includes a covering part located at the water outlet 222 and a non-covering part located on the shielding part and outside the water outlet. In this embodiment, the covering part is located in the central area, and the non-covering part is the middle part of the shielding part 221, so that the impacting water flow just flows down along the edge of the remaining area.

[0055] In this specific embodiment: the peripheral edge of the shielding portion 221 extends upward to form a lower peripheral wall 227; the ejector 21 includes an upper peripheral wall 213, the upper part of which extends outward to form a convex ring 214, an intermediate plate 215 is fixedly arranged in the upper peripheral wall, the intermediate plate is provided with the above-mentioned ejection hole 211, the upper peripheral wall is adapted to be installed in the lower peripheral wall, and the convex ring is supported on the end face of the lower peripheral wall. The lower shell 12 is provided with a through mounting hole, and the lower peripheral wall 227 is fixedly installed in the mounting hole. The outer diameter of the intermediate plate is smaller than the diameter of the shielding portion.

[0056] In this water outlet device: after the water flows through the upper shell 11 and enters the cavity 13, it is diverted to each water outlet component 2, and the ejector 21 decomposes the water flow into a high-speed water flow in the shape of a plum blossom. Part of the high-speed water flow (impact part) hits the shielding part 221 and decelerates, then flows out along the arc-shaped outer wall of the water outlet 222, forming a fan-shaped water curtain (semi-enclosed water curtain 32); another part of the high-speed water flow (straight-through part) will directly pass through the central area of ​​the water outlet, forming a splash with a strong impact force (straight-through water flow 31), and the outer circle water curtain surrounds the inner circle straight-through water. The water splash from a single water outlet is unique, with both a water curtain and straight-through water. The water splash has a beautiful appearance and a good flushing effect, and the splash caused by the impact of the straight-through water can be blocked by the outer circle water curtain. Moreover, the shape of the water outlet is distinctive and the appearance is highly recognizable.

[0057] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
