the two ends of the second valve shell assembly are respectively provided with a third water inlet and a fourth water inlet, the side wall of the second valve shell assembly is provided with the third water through hole, and the inside of the second valve shell assembly is provided with the branch water channels and the second surface; the third water inlet and the fourth water inlet respectively form a water inlet end and a water outlet end of the normally open waterway;

the second rotating component is coaxially and rotatably arranged in the second valve housing component and forms the second rotating part, the normally open water path is formed by matching with the second valve housing component, and the third surface is arranged in the normally open water path.

12. A shower as claimed in claim 11, wherein said second valve housing assembly comprises:

the first end of the second valve shell is provided with the third water inlet, the second end of the second valve shell extends into the water mixing channel, and the extending part of the side wall is provided with the third water passing hole;

the second valve seat is fixedly connected in the second valve shell, one end of the second valve seat is abutted against the inner wall of the shower body, and a fourth hole and at least two fifth holes which axially penetrate through the second valve seat are formed in the second valve seat; the port of one end of the fourth hole, which is abutted against the inner wall of the shower body, forms the fourth water inlet;

the second stator is positioned in the second valve shell, one end of the second stator is fixedly connected with the second valve seat, one surface of the second stator, which is deviated from the second valve seat, forms the second surface, and a sixth hole and at least two seventh holes which axially penetrate through the second stator are formed in the second stator; the sixth hole is communicated with the fourth hole and forms a part of the normally open waterway, and a port of the sixth hole on the second surface forms the third water passing port; each seventh hole is correspondingly communicated with a fifth hole and forms the water diversion path, and the port of the seventh hole on the second surface forms the fourth water passing port.

13. A shower as claimed in claim 12, wherein said second rotary assembly comprises:

the second shaft sleeve is coaxially and hermetically sleeved in the second valve shell and is in rotation stopping connection with the second operating part, and a central hole of the second shaft sleeve forms a part of the normally-open water path;

the second rotor is connected with the second shaft sleeve in a rotation stopping way, an eighth hole which penetrates through the second rotor in the axial direction is formed in the second rotor, and one end face of the second rotor forms the third surface; two ends of the eighth hole are respectively communicated with the central hole and the sixth hole of the second shaft sleeve; the mixed water passing hole extends to the side surface of the second rotor.

14. A shower as claimed in claim 8, wherein the shower body comprises:

the shell is internally provided with an installation cavity, and the side wall of the shell is provided with a top water outlet joint and a shower head water outlet joint; the top water spraying joint and the shower head water outlet joint respectively form two water outlet parts;

the water inlet body is arranged in the installation cavity and used for installing the temperature regulating valve core and the water diversion valve core, and the water mixing channel, the first water channel and the water outlet channel communicated with the water outlet part are arranged in the water inlet body.

15. A shower as claimed in claim 8, further comprising a first one-way valve and a second one-way valve; the first one-way valve is arranged at the water inlet end of the first valve body so as to prevent water flow or gas in the first valve body from flowing into the second pipe joint; the second one-way valve is arranged at the water inlet end of the second valve body so as to prevent water flow or gas in the second valve body from flowing into the first pipe joint.
