Abstract
The utility model discloses an integrated electric soldering iron with a protective function. The integrated electric soldering iron comprises a heating wire, a diode, bidirectional controllable silicon, a resistor, a first light emitting diode, a second light emitting diode, a mercury switch and a reed switch; when the integrated electric soldering iron is in use, all the parts can be selected according to demands; if high temperature is required for heating, the mercury switch is switched on, and the diode D is shorted out, so that the soldering iron is in a full-wave power supply state, and the two light emitting diodes both emit light; and when low temperature is required for heating, the mercury switch is switched off, and the diode D is subjected to half-wave rectification in a power supply, so that the soldering iron is in a half-wave power supply state. According to the integrated electric soldering iron, the temperature adjustment, the power supply on-off and display function are all designed in a handle of a common electric soldering iron, so that the integrated soldering iron is formed. When the integrated electric soldering iron is used for soldering a large-scale integrated circuit, a microcomputer control circuit, a CMOS (Complementary Metal-Oxide-Semiconductor Transistor) integrated circuit and a field effect transistor, the damage owing to electric leakage or poor grounding of the soldering iron is prevented.
Description
Technical field
The utility model relates to a kind of electric iron, relates in particular to a kind of integrated electric iron with defencive function.
Background technology
The existing present electric iron that adopts tends to because temperature is too high, electric iron imperfect earth, leak electricity these situation and cause the situation of damaging circuit in welding large scale integrated circuit, microcomputer control circuit, CMOS integrated circuit and FET.
Summary of the invention
The purpose of the utility model provides a kind of integrated electric iron with defencive function with regard to being in order to address the above problem.

The beneficial effect of the utility model is:
The utility model all designs the adjusting of temperature, the break-make and the Presentation Function of power supply within the handle of common electrical flatiron, has processed integrated flatiron.The utility model can not cause flatiron electric leakage or imperfect earth to cause damage in weldering large scale integrated circuit, microcomputer control circuit, CMOS integrated circuit and FET.
Description of drawings
Accompanying drawing 1 is the circuit structure schematic diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises heating wire RL, diode D, bidirectional triode thyristor SCR, resistance R, first LED 1, second LED 2, mercoid switch and tongue tube; The anodal of diode D is connected with an end of AC power and an end of mercoid switch simultaneously; The negative pole of diode D is connected with the other end of mercoid switch, the positive pole of first LED 1, the negative pole of second LED 2 and first end of bidirectional triode thyristor SCR simultaneously; Second end of bidirectional triode thyristor SCR is connected with first end of resistance R and first end of heating wire RL simultaneously; The control end of bidirectional triode thyristor SCR is connected with the negative pole of first LED 1, the positive pole of second LED 2 and second end of resistance R simultaneously; Second end of heating wire RL is connected with first end of tongue tube, and second end of tongue tube is connected with the other end of AC power.
Shown in accompanying drawing: the utility model is high and low, the apparent flatiron of pass band, and control circuit is installed in the handle.At ordinary times, flatiron is placed on the Iron Stand that permanent magnet is installed, tongue tube conducting under the effect of magnet, flatiron begins heating.During use, can select as required, during like the needs heat, make the mercoid switch conducting, diode D short circuit.Flatiron is in the all-wave power supply state, and two light emitting diodes are all luminous.When the needs low-temperature heat, mercoid switch is broken off, diode D makes halfwave rectifier in power supply, and flatiron is in the half-wave power supply state, therefore, a lumination of light emitting diode.During welding, flatiron leaves magnet, and tongue tube is broken off, and realizes automatically cutting off power source, and two Light-Emitting Diodes all extinguish, and electric iron stops heating.The utility model is to utilize waste heat to weld, and can not damage element because of flatiron is overheated, also can guarantee personal safety simultaneously.
