8. Through the arrangement of the first water outlet part, the water flow outlet through the second pipe part can be discharged in a required form.

9. The second water outlet part is arranged at the bottom of the switching channel, and specifically can be connected to a handheld shower head or other water outlet assemblies. By operating the lifting assembly, the shutter part moves to different positions along the vertical direction, so that the water passage port can be switched to communicate with one of the first water splitting port and the second water splitting port, the water outlet direction is changed, and different usage requirements are met.

10. When the pull rod and lifting handle are not lifted and stop at the lowest position, the pull rod is under the action of the elastic part and drives the shutter part to close by reliably the second water division port. At this time, the water passage port communicates with the first water division port. After the water mixing valve core controls the water mixing channel to communicate with the first water channel and/or the second water channel, water flows into the second pipe part , and the first water outlet part comes out of the water. When the pull rod and lifting handle are raised and stop at the highest position, the shutter part seals the shutter surface. At this time, the water passage port communicates with the second water division port. When the water mixing valve core opens the water mixing channel to communicate with the first water channel and/or the second water channel, water flowing into the switching channel from the The water outlet will flow out from the second water outlet hole. At this time, the pressure-bearing surface bears the action of water flow in the switching channel and reliably stops at the current position, thus the shutter part can reliably seal the surface shutter.
