Patent ID: 8299406

Claim:
An electronic temperature-sensing probe, comprising: a shell, a control base plate, a probe and a key group, wherein said control base plate is placed inside said shell; said probe with one end extending outside of said shell and the other end connected to said control base plate electrically is mounted in said shell; said key group with their inner ends connected to control contacts of said control base plate is mounted on a surface of said shell; said key group comprises a power switch key, temperature-adjusting keys and a high temperature switch key; said control base plate controls a power on/off of a heating element based on temperature control signals provided by said temperature-adjusting keys and said high temperature switch key, a power on/off signal provided by said power switch key and a temperature signal provided by said probe; wherein the temperature controlled by said temperature control signal provided by said high temperature switch key ranges from 245° C. to 275° C.; wherein the electrical heating element keeps heating for a duration when the high temperature switch key is pressed and the temperature controlled by said temperature control signal provided by said high temperature switch key automatically returns after the duration to the state before the high temperature switch key is pressed; wherein the electrical heating element is changed to the mode of power on/off by an interval when the temperature reaches a predetermined temperature.
