Another end connection electric capacity C1 one end, the electric capacity C1 other end connection thermistor NTC other end, thermistor NTC's is another
End connects power cathode jointly with low water level test point 2.
As a further improvement on the present invention, shown controller is also associated with buzzer, dry combustion method can occurring or spilling water shows
As when alarmed.
As a further improvement on the present invention, the surface metal temperature that the low water level test point is thermistor NTC is visited
Head, its outside are provided with insulation sleeve.
The beneficial effects of the invention are as follows：The present invention can detect water level and water temperature in kettle body in real time, when control circuit detects
When being less than low water level to water level, in automatic watering to kettle body；When detecting that water level reaches high water level, it is automatically stopped and adds water；When
When water temperature is less than design temperature, control circuit control heater element is begun to warm up；It is automatic to reduce when water temperature reaches design temperature
Power stops heating holding set water temperature, realizes that Intelligent watering is to boil water, has anti-dry, precisely anti-spilled, automatic watering, control
The safe and reliable characteristic such as temperature.
