The specific embodiment
As shown in Figure 3, the handle 1 of electric iron is established in it from master switch 2, and handle 1 connects welding body 3.As shown in Figure 1, temperature control circuit comprises selector switch, and the output of selector switch K1 connects reduction voltage circuit, and reduction voltage circuit is made of step-down rectifier diode D1; Reduction voltage circuit diode D1 output connects the controllable silicon temperature-adjusting circuit, and the controllable silicon temperature-adjusting circuit comprises controllable silicon V, and the output of controllable silicon V connects diode D2, is connected resistance R 2 and capacitor C between the trigger end of controllable silicon V and the output; Be connected resistance R 1, resistance R 3 between the trigger end of controllable silicon V and the input; The output of controllable silicon temperature-adjusting circuit connects flatiron heating core L; Selector switch K2 output connects reduction voltage circuit, and reduction voltage circuit is made of step-down rectifier diode D3; Reduction voltage circuit diode D3 output connects flatiron heating core L.Selector switch also comprises output selecting side K3, and selector switch K3 directly is connected flatiron heating core L with the input power supply.Three duties of electric iron are equipped with the duty indicating circuit, and the duty indicating circuit comprises light emitting diode and dropping resistor.Be respectively light emitting diode B1 and dropping resistor R4; Light emitting diode B2 and dropping resistor R5; Light emitting diode B3 and dropping resistor R6.
As shown in Figure 2, comprise insulation board 4 from the master switch selector switch, the two ends of insulation board 4 connect conduction output contact 5,6 respectively, establish conduction power shaft 7 on the insulation board 4, conduction power shaft 7 is hinged with seesaw 8, establish respectively under seesaw 8 links conductive contact 9,10, two conductive contacts 9,10 all with conduct electricity power shaft 7 conductings, establish slot rolling 11 on the seesaw 8, establish spin 12 in the slot rolling 11.Block 13 is established at slot rolling 11 two ends.
The operation principle of this flatiron is: when flatiron does not use, it carries Iron Stand makes flatiron be inclined upwardly 35 °, spin is rolled into the top of handle under the effect of deadweight, make K switch 1 conducting, is 110 volts through diode D1 with 220 volts voltage commutation step-down, control out one 80 volts voltage through controllable silicon V again and send flatiron heating core L through diode D2, this moment, flatiron produced 190～230 ℃ scolding tin melting temperature; When needs welded, the operator picked up flatiron, and spin is rolled under the effect of gravity, and K1 is disconnected, and connected K2, and 220 volts of power supplys are 110 volts through diode D3 rectification step-down, made solder horn produce 350 ℃ suitable welding temperature; If environment temperature on every side is lower, rotate flatiron, K2 is disconnected, K3 connects, and the flatiron heating core directly is connected with the input power supply, produces about 400 ℃ temperature.Three kinds of duties are respectively by light emitting diode B1, B2, B3 indication.
