Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figures 1 to 4, the novel touch electricity-saving flatiron of the present embodiment, it comprises touch control unit 1, main control unit 2, heating 3 and supply control unit 4; Wherein, touch control unit 1 can according to circumstances be arranged on the handle sidewall of electric iron, heating 3 is arranged at inside the bottom surface of electric iron, main control unit 2 and supply control unit 4 are arranged in the body of electric iron, simultaneously, supply control unit 4 and heating 3 are electrically connected with 220V city respectively, and supply control unit 4 provides 5V operating voltage to touch control unit 1 and main control unit 2, and the triggering signal that main control unit 2 exports according to touch control unit 1 controls heating element heater 3 break-make; The present embodiment, touch control unit 1 comprises soft-touch control a, the first triode Q1 and the second triode Q2, soft-touch control a is connected to the base stage of the first triode Q1 by the first resistance R1, the grounded emitter of the first triode Q1, colelctor electrode connect the base stage of the second triode Q2 by the second resistance R2, the emitter stage of the second triode Q2 connects supply control unit 4, colelctor electrode connects main control unit 2 and by the 3rd resistance R3 that is arranged in parallel and the first electric capacity C1 ground connection.
So, when people touches the contact of soft-touch control a, contact is by the noise signal in human body admission of air, this signal amplifies through the two-stage of the first triode Q1 and the second triode Q2, and after passing through the filter circuit filtering be made up of the 3rd resistance R3 and the first electric capacity C1, using state signal as electric iron is admitted in main control unit 2, to control heating 3 ON operation eventually through main control unit 2.
The main control unit 2 of the present embodiment comprises an a PIC16C628A type main control chip U and controllable silicon D; Wherein, the control pole that the RB7 pin of main control chip U connects the colelctor electrode of the second triode Q2, RB3 pin connects controllable silicon D also connects supply control unit 4 by the 4th resistance R4, and heating 3 is then connected with 220V civil power by controllable silicon D.So, can utilize on the circuit of controllable silicon D as the heating 3 of gate-controlled switch devices in series inside iron plate, the control pole that resistance R4 can be main control chip U control controllable silicon D provides pull-up current; Main control chip U is after the signal receiving touch control unit 1 output, and the high level that main control chip U exports can trigger the control pole of controllable silicon D, and then controllable silicon D controls heating 3 power stage.Meanwhile, if soft-touch control a midway does not receive signal, then along with the prolongation of time out, the angle of flow and the average voltage of controllable silicon D reduce piecemeal, and the power output of heating 3 also progressively decays, thus reach energy-saving and cost-reducing effect.
For ensureing the reliability of main control chip U work, the supply control unit 4 of the present embodiment comprises the rectifier bridge, PC817 type photoelectrical coupler A and the 3rd triode Q3 that are made up of diode D1-D4; Wherein, the two ends that the input of rectifier bridge is connected with 220V civil power, output is connected to the light emitting source of photoelectrical coupler A, the grounded emitter of the light-receiving device of photoelectrical coupler A, colelctor electrode connect the base stage of the 3rd triode Q3 by the 5th resistance R5, the emitter stage of the 3rd triode Q3 respectively with the VRE pin that emitter stage is connected with the 4th resistance R4, colelctor electrode is connected main control chip U of the second diode Q2.So, rectifier bridge is utilized to provide pulsating direct current waveform for photoelectrical coupler A, when waveform is handed over more from peak to zero point, photoelectrical coupler A will close, 3rd triode Q3 can not conducting, the current potential flowing to main control chip U is zero, and main control chip U can complete a zero passage detection thus, and for main control chip U, next step controls controllable silicon D and provides starting point.
In addition, enrich the function of electric iron further, the electric iron of the present embodiment also comprises and to be connected with main control chip U and to be controlled by the acousto-optic warning unit 5 of main control chip U, and the acousto-optic warning unit 5 of the present embodiment can be made up of components and parts such as loudspeaker, several resistance and several light emitting diodes; So, when soft-touch control a does not receive signal, main control chip U then controls acousto-optic warning unit 5 action, to remind user of service.
