The invention discloses a rechargeable lithium battery electric soldering iron device with temperature regulation, temperature control and constant temperature functions. According to the rechargeablelithium battery electric soldering iron device, real-time monitoring of the temperature of an electric soldering iron with a built-in thermocouple is achieved through the design of a 32-bit single-chip microcomputer and an analog circuit; technical optimization is carried out based on an existing portable electric soldering iron, and real-time temperature detection is carried out through the built-in thermocouple of the electric soldering iron, and therefore, boosting of a single lithium battery is achieved, the magnitude of the output voltage is controlled, the temperature compensation is realized, and the constant temperature of an electric soldering iron head is output within the full-voltage range of the lithium battery. According to the constant-temperature control device, a voltagestabilizing circuit module is designed, and stable power supply voltage required by the single-chip microcomputer and a control system is realized by taking power from the lithium battery, and therefore, continuous power supply to the rest modules is achieved, an output power supply can realize the stable power supply voltage required by the single-chip microcomputer and the control system, work at the lowest voltage of 3V is achieved, and then the work of one single lithium battery is realized. The voltage stabilizing circuit module is a key design circuit of the design and aims to stabilizethe voltage required by the output circuit.
