When the shower 100 provided in this embodiment is used:

when water with higher temperature is needed (such as in winter), the thermostatic valve 12 is opened and adjusted to a proper state, so that the hot water end 122 of the thermostatic valve 12 is opened to be larger, the hot water joint 40 and the cold water joint 30 respectively receive hot water and cold water from the hot water wall outlet pipe and the cold water wall outlet pipe, the hot water flows into the thermostatic valve 12 through the hot water channel 216, the second hot water channel 217 and the first water inlet channel in sequence, the cold water flows into the thermostatic valve 12 through the cold water channel 112, after the thermostatic valve 12 mixes the hot water and the cold water, the temperature sensing element in the thermostatic valve adjusts the water inlet proportion of the cold water end 121 and the hot water end 122 according to the water temperature change, the final hot water inflow amount and the final cold water amount are kept constant, the mixed water flows out through the mixed water end 123 and then flows into the water diversion valve 22 through the first water mixing channel 111 and the second water mixing channel 212, the first output end 222 or the second output end 223 on the water diversion valve 22 delivers the mixed water to the connector 23, the mixed water eventually exits the first outlet end 233 or the second outlet end 234 on the connector 23 for use by the user.

When it is desired to use water having a lower temperature (e.g., in summer), the thermostatic valve 12 is opened and adjusted to an appropriate state, and the hot water end 122 of the thermostatic valve 12 is likewise opened to a larger value, and the flow rate adjustment valve 14 is also opened at the same time. The hot water joint 40 and the cold water joint 30 respectively receive hot water and cold water from the hot water wall outlet pipe and the cold water wall outlet pipe, the hot water sequentially flows into the thermostatic valve 12 through the hot water receiving channel 216, the second hot water channel 217 and the first water inlet channel, the cold water partially flows into the thermostatic valve 12 through the cold water receiving channel 112, the thermostatic valve 12 mixes the hot water and the cold water, a temperature sensing element therein adjusts the water inlet ratio of the cold water end 121 and the hot water end 122 according to the change of the water temperature, the final hot water quantity and the cold water quantity are kept constant, the premixed water flows out into the flow channel 131 and the first water mixing channel 111 through the water mixing end 123, at this time, the other part of the cold water flowing out from the cold water receiving channel 112 sequentially flows into the flow channel 131 through the first annular groove 134, the groove 135, the first injection groove 135 and the second injection groove 134 and sequentially flows into the first water mixing channel 111 through the first annular groove 135 and the first injection groove and the third injection groove, so as to compensate the premixed water and reduce the water temperature to form the final mixed water, then the mixed water flows into the shunt valve 22 through the second mixed water channel 212, the first output end 222 or the second output end 223 on the shunt valve 22 delivers the mixed water to the connector 23, and the mixed water finally flows out from the first water outlet end 233 or the second water outlet end 234 on the connector 23 for the user to use, and during the use, the final water outlet temperature can be adjusted by adjusting the flow control valve 14.

When the water outlet path needs to be adjusted, the input end 221 of the shunt valve 22 is communicated with the first output end 222 or the second output end 223 by operating the shunt valve 22, so that the shower head/top of the shower 100 can spray water or the water can be discharged from the water outlet tap 60.

The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting.
