The water temperature regulating valve and the water flow guide 40 are disposed in the body 20. The water temperature can be adjusted and the water can be controlled by operating the control rod 50.
The water flow guide 40 is disposed at a lower end of the water temperature regulating valve 30. A hot water pipe 23 and a cold water pipe 24 are introduced into the water temperature regulating valve 30 via the water flow guide 40.
The warm water or cold water flowing out of the water temperature regulating valve 30 can flow out from a second outlet passage 41 of the water flow guide 40.

[0015] The outlet hose 60 is concealed in the outlet pipe 21 of the body 20 as a water passage of warm water or cold water. Please refer to FIG. 6, the inner end of the outlet hose 60 is fixed with a metal joint 61 and the outer end is a water outlet 62. A first leakage proof ring 611 is embedded in the outer wall of the inner end of the metal joint 61. The metal joint 61 is provided with a neck portion 612 whose outer diameter is tapered from the inside to the outside.
The neck portion 612 is located outside the first leakage proof ring 611.The inner end of the metal joint 61 can be inserted into the second outlet passage 41 of the water flow guide 40, and the first leakage proof ring 611 is provided to prevent leakage. One sidewall of the second outlet passage 41 is provided with a radially extending screw hole 411. And, a screw 412 is screwed into the screw hole 411 and urges the neck portion 612 of the metal joint 61 to prevent the metal joint 61 from coming out of the second outlet passage 41. Due to the tapered shape of the neck portion 612, it is ensured that the metal joint 61 does not come out of the second outlet passage 41. The water outlet 62 of the outlet hose 60 is provided with an outlet end 621. The water that has flowed out of the water flow guide flows out through the outlet end 621 through the passage of the outlet hose 60.

[0016] The first outlet passage 22 of the outlet pipe 21 of the body 20 is a two-stage screw hole, and the diameter of the screw hole at the inner end is smaller than the diameter of the screw hole at the outer end. A flat groove 211 is disposed in the outlet pipe 21, and the flat groove 211 is located above the first outlet passage 22. The water outlet 62 of the outlet hose 60 is inserted into the flat groove 211 just in unison. The center of the positioning seat 70 is a perforation 71.
