[0033] The water inlet portion 11 and the mounting sleeve 13 are vertically fixed together, and the water inlet portion 11 has a water inlet outlet 111, and the water inlet outlet is connected to the inner hole of the mounting sleeve 13, so that the water inlet portion 11 and the mounting sleeve 13 cooperate to form a three-way structure. As needed, the water inlet portion 11 and the mounting sleeve 13 may not be vertical, and the mounting sleeve 13 may be a cylindrical body as a whole or include a plurality of spaced connection rings and a fixing strip fixed to two adjacent connection rings.

[0034] The water outlet part 12 has two water channels 121, and the water channels 121 are provided with water inlets 1211, and the water inlets of the two water channels 121 are arranged at intervals along the sliding direction; the water outlet part 12 includes a pipe 122, and a blocking part 123 is provided in the middle of the pipe 122. The inner hole of the pipe 122 is divided into the above-mentioned two water channels 121 through the blocking part 123; the water inlet is arranged inside and outside the pipe 122, and the water inlets of the two water channels 121 are respectively arranged on both sides of the blocking part 123. The pipe fitting 122 is fixedly mounted in the mounting sleeve 13, and the fixing is such that the first end of the mounting sleeve 13 extends inwardly to form a first inner flange 131, and the first inner flange 131 is fixedly mounted on the outer wall of the pipe fitting 122, and the first inner flange 131 and the outer wall of the pipe fitting 122 are connected by threads, and the pipe fitting 122 and the water inlet part 11 are relatively fixedly mounted by the fixing, and the water outlet part 12 and the water inlet part 11 are relatively fixedly mounted, and the water inlet of the two water channels 121 and the water inlet outlet of the water inlet part 11 are connected. In this embodiment, the water outlet part 12 includes a pipe fitting, and the pipe fitting can be a single pipe fitting with a barrier part as required, or two pipe fittings with one end closed, and the closed ends of the two pipe fittings are aligned and fixedly mounted, and the closed ends of the two pipe fittings cooperate to form a barrier part.

[0035] The control part 2 includes a sleeve 21 that is slidably connected to the outside of the water outlet part 1. The sleeve 21 has a control area located between the water diversion inlet of the two water diversion paths 121 and the water inlet outlet of the water inlet part 11. The sliding of the sleeve 21 can use the control area to control the two water diversion inlets to switch and connect to the water inlet outlet. In the specific structure: the sleeve 21 is arranged between the mounting sleeve 13 and the water outlet part 12, which can improve the stability and reliability of sliding; the control area of ​​the sleeve 21 is provided with a connecting port 211 that runs through the inside and outside, and the connecting port 211 is always connected to the water inlet outlet of the water inlet part 11, and the sliding of the sleeve 21 at least controls the connecting port 211 of the sleeve 21 to connect to the water diversion inlet of any water diversion path 121, and the connected water diversion path 121 discharges water, while the other staggered water diversion path does not discharge water. Figure 3 and Figure 4 shown.

[0036] Two outer sealing parts 212 are arranged between the sliding sleeve 21 and the connecting sleeve 13 at intervals along the length direction of the pipe 122. If the outer sealing part 212 is a sealing ring, the water inlet outlet of the water inlet part 11 is between the two outer sealing parts 212, that is, in the entire stroke of the relative sliding of the sliding sleeve 21, the water inlet outlet of the water inlet part 11 is between the two outer sealing parts 212. The two outer sealing parts 212 form an annular cavity 213 that is constantly connected to the water inlet outlet between the sliding sleeve 21 and the connecting sleeve 13. The communication port 211 is located between the two outer sealing parts 212 and is constantly connected to the annular cavity 213. In this embodiment, the bottom wall corresponding to the annular cavity constitutes the above-mentioned control area.

[0037] An inner sealing portion 124 is provided between the control area of ​​the sleeve 21 and the water outlet part 12, and three inner sealing portions 124 are provided outside the pipe 122. If the inner sealing portion 124 is a sealing ring, the three inner sealing portions 124 are arranged at intervals along the length direction of the pipe and define two intervals. The water inlets of the two water channels are respectively located at the two intervals. The provision of the inner sealing portion can increase the switching effect, which not only improves the switching feel, but also avoids water outlet from the other water channel when switching to one water channel, thereby avoiding water leakage.

[0038] In this embodiment: the water inlet part 11 is a fixed pipe, one end of which can be fixed to the wall, such as by an expansion screw, and the other end constitutes the above-mentioned water inlet outlet 111; the fixed pipe is provided with a mounting hole running through the inside and outside, and the mounting hole is connected to a water inlet connector 112 that can be connected to an external water source, so that the external water source can be delivered to the water outlet part 12 through the water inlet connector 11, the fixed pipe and the water inlet outlet.

[0039] In this embodiment, if the upper end of the pipe 122 is connected to the head shower, when the first water channel flows out, the head shower flows out. Figure 3As shown; if the lower end of the pipe 122 is provided with a water outlet connector 125, the water outlet connector 125 is connected to the hand-held shower, then when the second water channel is discharged, the hand-held shower is discharged, such as Figure 4 shown.

[0040] In this embodiment: the control part 2 also includes an operating part, and the operating part is connected to the sliding sleeve 21 in a transmission manner so as to drive the sliding sleeve 21 to slide, thereby improving the convenience of switching. The operating part includes an operating sleeve 22, and the operating sleeve 22 and the sliding sleeve 21 are fixedly assembled together. The sliding sleeve 21 has an extended end extending beyond the first end of the mounting sleeve 13, and the extended ends of the operating sleeve 22 and the sliding sleeve 21 are fixedly connected together through a spacer, and a space is formed between the operating sleeve and the sliding sleeve, and the fixed connection is such as a threaded connection, and the spacer is such as an outer convex ring 214 protruding outward from the extended end of the sliding sleeve 21. The mounting sleeve 13 and the spacer are adapted so that the sliding sleeve is adapted to slide on the inner wall of the mounting sleeve, and the operating sleeve is adapted to slide on the outer wall of the mounting sleeve. Further, the sliding sleeve is also sleeved outside the water outlet joint 125. The above structure can improve the stability of the sliding of the operating sleeve and the sliding sleeve, and improve the sliding feel. In this embodiment, an operating part is added, but it may not be provided according to needs. For example, the sliding sleeve is slidably connected between the mounting sleeve and the water outlet part and at least a part of the sliding sleeve extends out of the mounting sleeve, and the extended part constitutes the user's operating part.

[0041] In this specific implementation method: the switching feel is light, when the water pressure is 3Bar, the switching force value is less than 15N, and the hydraulic force is balanced; the sliding sleeve is used to move the switch, which can reduce the occupied space, the structure is compact, and the outer diameter is limited to 20.6 space; the switching valve is highly versatile and can be used for various shower water outlet devices

[0042] Figure 5 This is the first application example of the water channel switching mechanism. The water inlet part of the water channel switching mechanism is a fixed pipe. The first branch water channel is connected to the head shower 3 through the L-shaped pipe 31, and the second branch water channel is connected to the hand shower 4 through the hose 41. When switching is required, the user only needs to slide the operating sleeve 22 up and down. The first branch water channel and the second branch water channel do not need to be moved. The first branch water channel and the second branch water channel are fixed relative to the water inlet part, which is easy to install, easy to operate, and simple in structure.
