The water outlet switching apparatus C has a first water outlet channel 11, a second water outlet channel 21, and a switching valve core 2 that controls whether the first water outlet channel 11 and the second water outlet channel 21 discharge water. The handheld shower head B is detachably connected to the water outlet switching apparatus C, and a water inlet end of the handheld shower head B communicates with the second water outlet channel 21 via a flexible pipe (not shown in the figure). The top spray shower head A is connected to the water outlet switching apparatus C via two water-flowing swing rods D, first ends of the water-flowing swing rods D are rotatably connected to two sides of the water outlet switching apparatus C, respectively, and second ends of the two water-flowing swing rods D are rotatably connected to the top spray shower head A. A water flowing channel D1 that enables communication between an inner cavity of the top spray shower head A and the first water outlet channel 11 is formed in the water-flowing swing rod D. A first sealing ring E and a wear-resistant damping piece 7 are clamped at a rotation junction between the water-flowing swing rod D and the water outlet switching apparatus C, and a second sealing ring F is clamped at a rotation junction between the water-flowing swing rod D and the top spray shower head A.

In the present invention, the top spray shower head A is connected to the water outlet switching apparatus C via the two water-flowing swing rods D. The first ends of the two water-flowing swing rods D are rotatably connected to the two sides of the water outlet switching apparatus C, respectively, and the second ends of the two water-flowing swing rods D are rotatably connected to the top spray shower head A. This arrangement allows the top spray shower head A to rotate around the water-flowing swing rods D and the water-flowing swing rods D to rotate around the water outlet switching apparatus C. Therefore, in the present invention, the top spray shower head A and the water-flowing swing rods D are rotated to adjust the water outlet angle of the top spray shower head flexibly and stably with a wide range. The inner cavity of the top spray shower head A communicates with the first water outlet channel 11 of the water outlet switching apparatus C through the water flowing channel D1 of the water-flowing swing rod D. This enhances the integration of the combined shower head of the present invention. Additionally, the first sealing ring E is clamped at the rotation junction between the water-flowing swing rod D and the water outlet switching apparatus C, and the second sealing ring F and the wear-resistant damping piece 7 are clamped at the rotation junction between the water-flowing swing rod D and the top spray shower head A. The first sealing ring E and the second sealing ring F can provide a waterproofing function, and the wear-resistant damping piece 7 stably provides rotational damping, ensuring that the top spray shower head A can be positioned at the desired water outlet angle.

In the embodiments of the present invention, the water outlet switching apparatus C includes a switching body 1 and the switching valve core 2. The switching body 1 may be at least formed by connecting a body housing 101, a fixing holder 102, a limiting base 103, and a body face cover 104. The switching body 1 is provided with a water inlet port 12, a switching channel 13, and the first water outlet channel 11. The water inlet port 12 may be connected to a universal joint 6, so as to adjust the angle of the water outlet switching apparatus C. An inner wall of the switching channel 13 is provided with a water inlet hole 131 and a water outlet hole 132 that are opposite, and the water inlet hole 131 and the water outlet hole 132 respectively communicate with the water inlet port 12 and the first water outlet channel 11.

The water flowing groove 22 of the switching valve core 2 movably communicates with the water inlet hole 131 and the water outlet hole 132, and the water flowing through-hole 23 of the switching valve core 2 movably communicates with the water inlet hole 131. When the switching valve core 2 is rotated so that only the water flowing through-hole 23 of the switching valve core 2 communicates with the water inlet hole 131, the water inlet port 12 communicates with the second water outlet channel 21 via the water flowing through-hole 23, and the second water outlet channel 21 discharges water, causing the handheld shower head B to discharge water. When the switching valve core 2 is rotated so that only the water flowing groove 22 communicates with the water inlet hole 131 and the water flowing groove 22 communicates with the water outlet hole 132, the water inlet port 12 communicates with the first water outlet channel 11 via the water flowing groove 22, and the first water outlet channel 11 discharges water, causing the top spray shower head A to discharge water. When the switching valve core 2 is rotated so that the water flowing through-hole 23 of the switching valve core 2 communicates with the water inlet hole 131 and the water flowing groove 22 communicates with both the water inlet hole 131 and the water outlet hole 132, the water inlet port 12 communicates with both the first water outlet channel 11 and the second water outlet channel 21, and the first water outlet channel 11 and the second water outlet channel 21 discharge water, causing both the top spray shower head A and the handheld shower head B to discharge water.

In the embodiments of the present invention, the outer wall of the switching valve core 2 is provided with a water-flowing sealing ring 4 that surrounds the water flowing through-hole 23, and the water-flowing sealing ring 4 sealingly fits with the inner wall of the switching channel 13.

The hinge channel 15 is provided with a switching body 1, and a side wall of the hinge channel 15 is provided with a water outlet opening 151 in communication with the first water outlet channel 11. The two first sealing rings E fitting with the first connecting joint D2 sealingly fit with an inner wall of the hinge channel 15, and the water flowing inlet D21 of the first connecting joint D2 communicates with the first water outlet channel 11 via the water outlet opening 151. This arrangement allows the water-flowing swing rod D to rotate relative to the water outlet switching apparatus C with rotational damping, and the water flowing channel D1 of the water-flowing swing rod D always communicates with the first water outlet channel 11 without water leakage. The water outlet switching apparatus C is fixedly provided with a wear-resistant damping piece 6 that abuts against the side surfaces of the first connecting joints D2 of the two water-flowing swing rods D. The wear-resistant damping piece 6 can be embedded in a groove within the water outlet switching apparatus C to prevent displacement. The wear-resistant damping piece 6 simultaneously abuts against the side surfaces of the first connecting joints D2 of the two water-flowing swing rods D, which helps to enhance the rotational damping between the water-flowing swing rods D and the water outlet switching apparatus C, thereby improving the stability of the water-flowing swing rods D.

The top spray shower head A is provided with a hinge passage A1 that rotatably accommodates the second connecting joint D3 of the water-flowing swing rod D, and a side wall of the hinge passage A1 is provided with a water inlet opening A11 in communication with the inner cavity of the top spray shower head A. The two second sealing rings F fitting with the second connecting joint D3 sealingly fit with an inner wall of the hinge passage A1, and the water flowing outlet D31 of the second connecting joint D3 communicates with the inner cavity of the top spray shower head A via the water inlet opening A11. This arrangement allows the top spray shower head A to rotate relative to the water-flowing swing rod D with rotational damping, and the water flowing channel D1 of the water-flowing swing rod D always communicates with the inner cavity of the top spray shower head A without water leakage. Further, a hinge rod A12 that is sleeved with the second connecting joint D3 is disposed in the hinge passage A1, and the hinge rod A12 is provided with a screw A3 to be in limited engagement with the second connecting joint D3, thus effectively preventing detachment of the second connecting joint D3.

In the embodiments of the present invention, the top spray shower head A has a fitting notch A2 for movable docking with the handheld shower head B. In this way, the top spray shower head A can be moved to dock with the handheld shower head B, which is combined with the water outlet switching apparatus C (see FIG. 1), and both the top spray shower head A and the handheld shower head B can be controlled simultaneously to discharge water, increasing the shower area.
