A fast-heating temperature-controlled electric soldering iron

Abstract

The invention provides an instantaneous temperature control electric iron. The instantaneous temperature control electric iron comprises an iron core embedded with a thermocouple; the temperature control electric iron also comprises a voltage comparison module, a signal detection module and an output control module, wherein the voltage comparison module comprises a first operational amplifier and a second operational amplifier and is used for comparing input voltage between two input ends of the first operational amplifier and input voltage between two input ends of the second operational amplifier; the signal detection module is used for detecting a level signal of the thermocouple, which is adjusted through one input end of the first operational amplifier at the specified welding temperature and detecting a level signal of the thermocouple passing through the other input end of the first operational amplifier; the output control module is used for controlling the on or off of the temperature control electric iron. The temperature control electric iron solves the problems that a common electric iron easily leaks electricity, is short in service life, long in preheating time and limited to using places and the like. Moreover, the temperature control electric iron has the advantages of flexible power supply mode, wide temperature adjusting range, quick heating, quick temperature compensation, sensitive temperature control and the like.
