[0037] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —7:

[0038] A top sprayer includes a ring-shaped, hollow outer shell 1. Two hollow connecting pipes 2 are located at the rear end of the outer shell 1, each containing a water inlet pipe 3. A ring-shaped water outlet device is coaxially arranged inside the outer shell 1. The ring-shaped water outlet device includes a ring-shaped, hollow inner shell 4 and a water outlet column 5 whose inner hole connects to the inner cavity of the inner shell 4. The inner cavity of the inner shell 4 connects to one of the water inlet pipes 3. Multiple water outlet columns 5 are distributed circumferentially. The bottom surface of the outer shell 1 has external through holes 6 of matching number and position. A waterfall water outlet device is also provided inside the outer shell 1. The waterfall water outlet device includes a waterfall water outlet shell 7 whose inner cavity connects to another water inlet pipe 3. A strip-shaped groove 8 is provided on the inner ring of the outer shell 1. A strip-shaped water outlet portion is provided on the waterfall water outlet shell 7, which is inserted into the strip-shaped groove 8. A strip-shaped water outlet channel 9 is provided on the strip-shaped water outlet portion, connecting to the inner cavity of the waterfall water outlet shell 7.

[0039] The working principle of this utility model is as follows: Figure 1-7 As shown, when a large area of ​​rain shower-style water outlet is required, water enters through the inlet pipe 3 connected to the inner shell 4, and the water flows out through the inner hole of the water outlet column 5 via the inlet pipe 3 and the inner cavity of the inner shell 4; when a waterfall-style water outlet is required, water enters through the inlet pipe 3 connected to the waterfall outlet shell 7, and the water flows out through the strip-shaped water outlet channel 9 via the inlet pipe 3 and the inner cavity of the waterfall outlet shell 7.

[0040] In the attached diagram, Figure 2 , 4 Only the water inlet pipe 3 connecting the inner shell 4 is shown; the water inlet pipe 3 connecting the waterfall outlet shell 7 is not shown.

[0041] This utility model features a ring-shaped water outlet and a waterfall water outlet inside the outer shell 1, forming two water outlet methods: a large-area rain shower and a waterfall. This can meet the diverse needs of users. At the same time, the ring-shaped and hollow outer shell 1 forms a complete external structure. Both the ring-shaped water outlet and the waterfall water outlet are integral structures that can be placed inside the outer shell 1 as a whole. The ring-shaped water outlet and the waterfall water outlet are easy to assemble and convenient to install into the outer shell.

[0042] In this embodiment, the water outlet column 5 has multiple circumferentially distributed parts, and correspondingly, the external through hole 6 has multiple circumferentially distributed parts.

[0043] The specific structure of the annular water outlet device is as follows: Figure 1-4 As shown in Figure 7, the inner shell 4 includes a hollow lower inner shell 4a with an open upper end and an inner cover 4b covering the lower inner shell 4a. A sealing plate 10 is provided at the upper end of the water outlet column 5, fitting against the inner end face of the lower inner shell 4a. The inner cover 4b has an outer annular abutment portion 4c and an inner annular abutment portion 4d, whose lower ends respectively abut and seal against the sealing plate 10. The inner cover 4b, the outer annular abutment portion 4c, the inner annular abutment portion 4d, and the sealing plate 10 form an annular water outlet channel 11 connecting one of the water inlet pipes 3. The sealing plate 10 has a water outlet hole 12 connecting the annular water outlet channel 11 and the inner hole of the water outlet column 5. The bottom of the lower inner shell 4a has an inner through hole 13 for the water outlet column 5 to extend out, and the water outlet column 5 extends through the inner through hole 13 to the outside of the outer through hole 6. This design effectively prevents leakage, has a simple structure, and facilitates subsequent welding and sealing of the lower inner shell 4a and the inner cover 4b.

[0044] Furthermore, the water outlet 12 is coaxially arranged with the inner hole of the water outlet column 5, and both are tapered holes with a larger diameter at the top and a smaller diameter at the bottom. The diameter of the lower end of the water outlet 12 is the same as the diameter of the upper end of the inner hole of the water outlet column 5.

[0045] Furthermore, the water outlet column 5 is a frustum-shaped cylinder with a larger diameter at the top and a smaller diameter at the bottom, and the water outlet column 5 is arranged coaxially with its inner hole.

[0046] Installation structure of the annular water outlet device and the outer shell 1: The outer shell 1 is provided with multiple mounting posts 19, and the outer periphery of the inner lower shell 4a is provided with multiple mounting plates 20.

[0048] In order for the water in the annular water outlet device to converge towards the center, the water outlet column 5 and the sealing plate 10 are integrally structured and made of silicone. The axes of the inner through hole 13 and / or the outer through hole 6 are inclined from top to bottom towards the center, and the axis of the water outlet column 5 is inclined from top to bottom towards the center.

[0049] Furthermore, the sealing plate 10 gradually slopes upward from the outside to the inside.

[0050] Connection method between the inner lower shell 4a and the inner cover 4b: The edge of the inner lower shell 4a and the edge of the inner cover 4b are fixed by welding.

[0051] To prevent the sealing plate 10 from bulging upwards in the middle and affecting the water output, the inner end face of the inner lower shell 4a is recessed to form an installation groove 14. The sealing plate 10 is placed in the installation groove 14. The inner cover 4b is provided with an abutment post 15 whose lower end abuts against the sealing plate 10. The abutment post 15 is located between the outer annular abutment part 4c and the inner annular abutment part 4d, and multiple posts are evenly distributed around the circumference.
