As shown inFIGS.1to9, the present invention discloses a combined shower head, including a top spray shower head A, a handheld shower head B, and a water outlet switching apparatus C. The water outlet switching apparatus C has a first water outlet channel11, a second water outlet channel21, and a switching valve core2that controls whether the first water outlet channel11and the second water outlet channel21discharge 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 channel21via 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 D1that enables communication between an inner cavity of the top spray shower head A and the first water outlet channel11is formed in the water-flowing swing rod D. A first sealing ring E and a wear-resistant damping piece7are 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 channel11of the water outlet switching apparatus C through the water flowing channel D1of 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 piece7are 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 piece7stably 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 body1and the switching valve core2.

The water flowing groove22of the switching valve core2movably communicates with the water inlet hole131and the water outlet hole132, and the water flowing through-hole23of the switching valve core2movably communicates with the water inlet hole131. When the switching valve core2is rotated so that only the water flowing through-hole23of the switching valve core2communicates with the water inlet hole131, the water inlet port12communicates with the second water outlet channel21via the water flowing through-hole23, and the second water outlet channel21discharges water, causing the handheld shower head B to discharge water. When the switching valve core2is rotated so that only the water flowing groove22communicates with the water inlet hole131and the water flowing groove22communicates with the water outlet hole132, the water inlet port12communicates with the first water outlet channel11via the water flowing groove22, and the first water outlet channel11discharges water, causing the top spray shower head A to discharge water. When the switching valve core2is rotated so that the water flowing through-hole23of the switching valve core2communicates with the water inlet hole131and the water flowing groove22communicates with both the water inlet hole131and the water outlet hole132, the water inlet port12communicates with both the first water outlet channel11and the second water outlet channel21, and the first water outlet channel11and the second water outlet channel21discharge 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 core2is provided with a water-flowing sealing ring4that surrounds the water flowing through-hole23, and the water-flowing sealing ring4sealingly fits with the inner wall of the switching channel13.
