Two-stage retractable soldering iron cooling rack

Abstract

A two-stage telescopic electric soldering iron radiating frame is composed of an electromagnetic valve, a fan, a sleeve, a plug, a control module, a soldering iron frame, a sensor, a diode and a pull rod. The two-stage telescopic electric soldering iron radiating frame is characterized in that a first pin and a second pin of the control module are connected with the fan, a third pin of the control module is connected with the sensor, a fourth pin and a seventh pin of the control module are led out of a power plug, the diode is in serial connection between the fourth pin and the plug, a fifth pin of the control module is connected with a primary coil of the electromagnetic valve, a sixth pin of the control module is connected with a secondary coil of the electromagnetic valve, and an eighth pin of the control module is in parallel connection with a negative electrode public end of the primary coil and the secondary coil of the electromagnetic valve. The control module can enable the primary coil or the secondary coil to be conducted to drive the pull rod to be switched between the beginning position, the primary coil position and the final position at the right moment according to temperature signals of the sensor.

Description

technical field [0001] The invention relates to a temperature control technology of an electric soldering iron when it is in use, and specifically relates to a two-stage telescopic electric soldering iron cooling frame. Background technique [0002] At present, although the adjustable constant temperature electric soldering irons on the market can control the working temperature range of the electric soldering iron, it is unavoidable to place the electric soldering iron temporarily due to the board circuit or personnel relationship during the use of the electric soldering iron. Short-lived, that is, the dormant state. At this time, although the electric soldering iron is in the set constant temperature state, due to the relatively concentrated heat, the soldering iron tip is easy to oxidize, and at the same time, it also causes a waste of energy. Contents of the invention [0003] The purpose of the present invention is to provide a two-stage telescopic electric soldering...

[0002] At present, although the adjustable constant temperature electric soldering irons on the market can control the working temperature range of the electric soldering iron, it is unavoidable to place the electric soldering iron temporarily due to the board circuit or personnel relationship during the use of the electric soldering iron. Short-lived, that is, the dormant state. At this time, although the electric soldering iron is in the set constant temperature state, because the heat is relatively concentrated, the soldering iron tip is easy to oxidize, and at the same time, it also causes a waste of energy
