Temperature drop controller for electric soldering iron

Abstract

The invention provides a temperature drop controller for an electric soldering iron. The temperature drop controller consists of a control module, a touch switch, an electric soldering iron socket, a temperature regulating switch and the like, and is characterized in that a first signal input end of the control module is connected with a touch switch, a second signal input end of the control module is connected with a temperature regulating switch, a first output end of the control module is connected with a temperature display, and a second output end of the control module is connected with the electric soldering iron socket. When the electric soldering iron is placed into an inner cavity of a support seat, the electric soldering iron is in contact with the touch switch, the touch switch is conducted, the control module lowers the work temperature of the electric soldering iron to a value between 100 DEG C and 120 DEG C, the temperature shows that the electric soldering iron is in a dormancy state, and only the buffer temperature needs to be provided for the electric soldering iron. After the electric soldering iron leaves the support seat, the touch switch is switched off, the temperature of the control module returns to the temperature range set by the temperature regulating switch.

Description

technical field [0001] The invention relates to a temperature control technology of an electric soldering iron, in particular to a temperature drop control device of an electric soldering iron. 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 object of the present invention is to provide a temperature drop control device for an electric soldering iron, wh...

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
