Abstract
The utility model discloses an efficient electric soldering iron which comprises a rectifying circuit, a thermistor, a resistor and a capacitor. Two ends of the input end of the rectifying circuit are connected with two ends of an alternating current power supply. The positive electrode of the output end of the rectifying circuit is connected with a first end of the thermistor, a first end of the resistor and a first end of an electric soldering iron heating pipe at the same time. The negative electrode of the output end of the rectifying circuit is connected with a first end of the capacitor and a second end of the electric soldering iron heating pipe at the same time. A second end of the thermistor is connected with a second end of the capacitor and a second end of the resistor at the same time. By means of the efficient electric soldering iron, a quick temperature rise can be realized without the need of manual operation; after the efficient electric soldering iron has a certain temperature rise, a normal heating state is switched to through automatic control. Therefore, the efficient electric soldering iron is convenient to use, saves time at the same time, and improves maintenance efficiency.
Description
Technical field
The utility model relates to a kind of electric iron control circuit, relates in particular to a kind of efficient electric iron.
Background technology
When the winter of weather cold or line voltage are lower, often feel inconvenient too slowly, the efficient of the electronic maintenance that slowed down owing to heating up after electric iron plugged in.
The utility model content
The purpose of this utility model provides a kind of efficient electric iron with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises rectification circuit, thermistor, resistance and electric capacity, the two ends of the input of described rectification circuit are connected with the two ends of AC power, the anodal of the output of described rectification circuit is connected with first end of first end of described thermistor, described resistance and first end of described electric iron heat-generating pipe simultaneously, the negative pole of the output of described dead resistance is connected with first end of described electric capacity and second end of described electric iron heat-generating pipe simultaneously, and second end of described thermistor is connected with second end of described electric capacity and second end of described resistance simultaneously.
The beneficial effects of the utility model are:
This adaptation is novel to need not manual operation, just can finish being rapidly heated, and reaches after certain temperature rise again to flatiron that automatic control is transformed into the normal heating state, thereby brings convenience to use, has also saved the time simultaneously, improves maintenance efficiency.
Description of drawings
Fig. 1 is circuit structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: the utility model comprises rectification circuit VD, thermistor PCT, resistance R and capacitor C, the two ends of the input of rectification circuit VD are connected with the two ends of AC power, the anodal of the output of rectification circuit VD is connected with first end of thermistor PCT, first end of resistance R and first end of electric iron heat-generating pipe RL simultaneously, the negative pole of the output of dead resistance VD is connected with first end of capacitor C and second end of electric iron heat-generating pipe RL simultaneously, and second end of thermistor PCT is connected with second end of capacitor C and second end of resistance R simultaneously.
As shown in Figure 1: when using electric iron, with its power supply incoming transport 220V socket.O.9 the 220V power supply becomes after full bridge rectifier VD rectification * the 220=198V pulsating dc voltage, because rectification circuit VD output two ends are connected to the filtering Yin road that thermistor PTC and capacitor C are composed in series.Begin at the beginning of thermistor PTC carries out charge and discharge in capacitor C, because the thermistor PTC element internal resistance of cold conditions very little (approximate straight-through), so the filtration efficiency of filter circuit will reach the highest this moment, the load both end voltage can rise to theoretical peak 220(2 radical sign)=314V about, under this supply voltage.The flatiron heart carries out Fast Heating and heats up.The charge and discharge electric current of capacitor C is rapidly heated behind the certain hour, owing to can make thermistor PTC slowly heat.Its internal resistance phase strain is big, makes to discharge and recharge time constant and strengthen, and filtration efficiency is reduced synchronously, slowly drops to a certain degree the back and keeps constant thereupon flatiron heat-generating pipe RL both end voltage.After preventing that thermistor PTC internal resistance is excessive, the load both end voltage descends lowly excessively, so add a compensating resistance R at thermistor PTC two ends again, thereby make the flatiron heart supply voltage after constant be stabilized in 220V, to keep the electric iron normal operating conditions.
