Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the embodiment of the present invention proposes a kind of insulating pot control circuit and system, its
Focus on：Including power-supply system, display system, temp measuring system and anti-dry system, the temp measuring system include thermistor 26,
Temperature control call wire 28 and temperature control wiring pole 14, the anti-dry system touch pin 27, pull-up resistor 17, anti-dry call wire including water level
29 and anti-dry wiring pole 15, the thermistor 26 and water level touch pin 27 and are placed in two-in-one probe 2, the temperature control call wire
28 one end couple thermistor 26, and other end connection temperature control wiring pole 14, the one end of anti-dry call wire 29 connection water level touches pin
27th, pull-up resistor 17 and thermistor 26, other end connection anti-dry wiring pole 15.The two-in-one probe 2 includes temperature probe
23rd, anti-dry probe 21 and seal closure 24, the bottom of temperature probe 23 is provided with fixed screw thread 25, the seal closure 24 in umbrella and with
Temperature probe 23 is connected as one, and the anti-dry pops one's head in 21 tops in cone, and bottom is in cylinder and is inserted in temperature probe
23 top, provided with filling insulating barrier 22 between the temperature probe 23 and anti-dry probe 21.The power-supply system, display system,
Temp measuring system and anti-dry system couple control chip.The power-supply system includes live wire electrode pole 12, neutral line electrode 13 and ground wire
Pole 16.The live wire electrode 12, neutral line electrode 13, ground wire pole 16, temperature control wiring pole 14 and anti-dry wiring pole 15 are located at the bottom of base 1
Portion.
In this specific embodiment, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, fixed screw thread 25 is tightened in kettle bottom, i.e.,
A kind of two-in-one probe 2 of insulating pot control circuit and system of the invention can be fixed.Then, the one end of temperature control call wire 28 is joined
Thermistor 26 is connect, other end connection temperature control wiring pole 14, the one end of anti-dry call wire 29 parallel connection water level touches pin 27, pull-up resistor
