A front side of the straight pipe portion 12 is connected to an outwardly extending plug portion 14 , and the plug portion 14 is a pipe body. And the interior is communicated with the installation space 121 .

The inner core body 20 is disposed in the installation space 121. As shown in FIG. 3 to FIG. 4 and FIG. 7, the bottom of the inner core body 20 has at least one water inlet channel 222. For example, the preferred embodiment has two inlet water channels 222. Water channels 222, wherein one water inlet channel 222 is used to introduce hot water to the inner core body 20, and the other water inlet channel 222 is used to introduce normal temperature cold water to the inner core body 20. One side of the connecting portion 14 has a water outlet hole 241 , and each of the water inlet channels 222 is communicated with the water outlet hole 241 through the control of a water control valve core 26 . 20 can control the total amount and proportion of the water flowing into each of the water inlet channels 222 and flowing out from the water outlet hole 241 . In other preferred embodiments, when the inner core body 20 is in the form of an adapter, each of the water inlet channels 222 is directly connected to the water outlet hole 241 .

As shown in FIG. 2 to FIG. 6 , the water outlet pipe assembly 30 includes an outer pipe 32 , an inner pipe 34 and a fixing pad 36 . The inner tube 34 can be made of a plastic material with certain elasticity and ductility. The inner tube 34 has an extension tube 341 inserted into the outer tube 32 , and both ends of the extension tube 341 are connected to a first end. 342 and a second end 343, the first end 342 has a first through hole 3421 in the middle that communicates with the extension tube 341, and a first flange 3422 is formed around the first end 342, the first The width of a flange 3422 is greater than the inner diameter of one end of the outer tube 32 and is fixed by an end edge abutting against the end.

The middle of the second end 343 has a second through hole 3431 communicating with the extension tube 341, and the width of the second end 343 is narrower than the inner diameter of the other end of the outer tube 32, so that the The other end of the outer tube 32 can be partially penetrated from the inside to the outside. The fixing pad 36 is detachably coupled to the periphery of the second end 343. The fixing pad 36 has a second flange 361 around it. The width of the two flanges 361 is larger than the inner diameter of the other end of the outer tube 32 and is fixed by the end edge abutting against the other end.
