the first shower head is further disposed with a second water diversion passage and a switch mechanism; the switch mechanism is coupled to the water supply passage, the first water diversion passage and the second water diversion passage to fluid communicate the water supply passage with one of the first and second water diversion passage; the cool water discharging passage is connected to the second water diversion passage, the second water diversion passage is connected to the second outlet portion.

2. The combined shower head with cool water discharging passage according to claim 1 , wherein the first shower head is further disposed with a check valve being disposed at the portion of the second water diversion passage connecting the cool water discharging passage and the switch mechanism.

3. The combined shower head with cool water discharging passage according to claim 1 , wherein the control mechanism is also a switch mechanism, the switch mechanism is coupled to the inlet passage, the water supply passage and the cool water discharging passage to fluid communicate the inlet passage with one of the water supply passage and the cool water discharging passage.

4. The combined shower head with cool water discharging passage according to claim 1 , wherein further comprising an operation portion being assembled in the first shower head and connected the control mechanism and the switch mechanism in transmission way to control the control mechanism and the switch mechanism.

5. The combined shower head with cool water discharging passage according to claim 4 , wherein the operation portion comprises an operation element being movably connected to the first shower head and being movable in a first track and a second track in relation to the first shower head; the operation element is disposed with a first transmission portion coupled to the control mechanism and a second transmission portion coupled to the switch mechanism; the operation element moves in the first track and the second track so as to respectively drive the control mechanism by the first transmission portion and drive the switch mechanism by the second transmission portion in transmission way.

6. The combined shower head with cool water discharging function according to claim 5 , wherein the operation portion is rotatably connected to the first shower head; the first track is a swing track of the operation element swinging from an initial position to a forward position in relation to the first shower head; the second track is a swing track of the operation element swinging from an initial position to a backward position in relation to the first shower head; the forward position and the backward position are arranged at two sides of the initial position.

7. The combined shower head with cool water discharging function according to claim 6 , wherein the end face of the operation element is protruding with a protruding base, the protruding base is disposed with a contact surface arranged about the rotating axis of the operation element with a various height of arc; the first transmission portion comprises the protruding base, the contact surface of the protruding base is connected to the control mechanism in transmission way; the end face of the operation element is protruding with a driving base, the second transmission portion comprises the driving base.

8.
