Integrated electric iron with protection function ----- Integration with the Protection of Electric Iron

Integrated electric iron with protection features, Integration with the Protection of Electric Iron Keywords: electric iron circuit In this article, the integrated iron iron is designed to adjust the temperature adjustment, power supply, and the display function, which is designed within the handle of ordinary electric iron, and has made a soldering iron. Also known as high, low, and cable. This soldering iron is not worried about the soldering iron leakage or grounding failure to use the soldering iron, the microcomputer control circuit, the CMO integrated circuit, and the field effect. High, low, and the cable is hot, it is on the power line in the handle. A normally open reed tube and a diode are skeed separately. And in the diode and a one-way mercury conductive switch (such as the drawings), the composition is high, low and off. usually. Place the soldering iron on the soldering iron frame installed with a permanent magnet, the reed tube is turned on under the action of the magnet, and the soldering iron begins to heat. The soldering iron rack is equipped with a high and low, and it can be selected as needed. When it is necessary to heat it, the soldering iron head is placed on the high-level, and the soldering iron head is turned on, and the diode is shorted. The soldering iron is in full wave power supply, both LEDs are emitted. When you need a low temperature heating, you should put the soldering iron on the low layer. The soldering iron is off at the low layer, the mercury is turned off, and the diode is half-wave rectification in the power supply. The soldering iron is in a half-wave power supply, therefore, one LED luminates. When soldering, the soldering iron leaves the magnet, turns the reed tube, realizes the automatic shutdown power supply, and the two light tubes are extinguished, and the iron iron stops heating. This soldering iron is welded using waste heat. It will not damage the components without overheating the soldering iron, and it can also guarantee personal safety. The soldering iron is characterized by simple and practical, and the temperature is adjusted with a high low position of the iron head. Move with the front and rear movement of the handle to achieve the opening. Therefore, the soldering iron is not available, or it may not unplug the power. The display function of the soldering iron can directly observe the high, low, off state of the soldering iron: high temperature double lights: low temperature single light is bright: turn off the double lights Author: Needle
