Temperature sensor 16 at water outlet 14 obtains the temperature for the water that water outlet 14 flows out after scaling operation, thus to adjust out
Coolant-temperature gage and scaling operation provide data and support that, if the water temperature in scaling operation rear valve body 10 is higher, user uses water suddenly at this time
It easily causes to scald, the output water temperature signal that temperature sensor 16 can will test is fed back, to scaling operation process
The aperture of water-mixing valve core 11 is adjusted, and forms closed feedback.In the above-described embodiments, as shown in Figure 1, water mixing valve 1 further includes
Switch valve core 17 at water outlet 14, and with driving mechanism 18 by connection, to control the switch of water outlet 14.
In this embodiment, the switch of water outlet 14 is controlled by the switch valve core 17 at water outlet 14, is on the one hand switched
Spool 17 closes the current floe condition of water flow at the water outlet 14 needed for Shi Kewei scaling operation provides, and switch valve core 17 is used when opening
The just common water in family；On the other hand, switch valve core 17 and driving mechanism 18 can send the switch of water outlet 14 by connection
Signal is remained to driving mechanism 18 when water flow sensing unit 15, which breaks down, can not provide inlet water stream flow regime signal
Just common water is enough guaranteed by Operation switch spool 17.Wherein switch valve core 17 is knob-type valve core, and it is convenient to operate.
