The invention discloses a control module for a cooling frame of an electric soldering iron. The control module for the cooling frame of the electric soldering iron is composed of a fan, a sleeve, a plug, a control module body, an iron stand and a sensor. The control module for the cooling frame of the electric soldering iron is characterized in that a first pin and a second pin of the control module body are connected with the fan, a third pin of the control module body is connected with the sensor, and the power plug is led out of a fourth pin and a fifth pin of the control module body. The plug is used for being connected with a socket of the electric soldering iron. When the sensor induces that the air temperature transmitted by the electric soldering iron exceeds 70 DEG C, the control module body starts the fan and makes the fan rotate and work to cool an iron head of the electric soldering iron. The control module body for the cooling frame of the electric soldering iron has the beneficial effects that the cooling frame of the electric soldering iron can cool the iron head when the electric soldering iron is in a dormant state, and accordingly the service life of the electric soldering iron is prolonged, and energy is saved.
