Fig. 1 is an electrical schematic diagram of the present utility model.

The utility model both can be assembled into supply socket formula temperature control analogue means separately, also can be positioned over electric fan inside, controlled automatically.Fig. 1 is example with the autonomous device, and its plug CT inserts civil power, and the electric fan plug inserts socket CZ of the present utility model.(K switch also can be attempted by amplifier A in the long periodic oscillation device when the K switch in the short period oscillator is closed ₃The inverting input resistance R ₁₇On, role is identical), the controllable silicon CR conducting always in the major loop makes socket CZ and civil power straight-through, the utility model is inoperative, the work of electric fan with stop to finish by fan self button.

During the utility model work, need K switch is placed open position, when rigidly connecting energize, the electrochemical capacitor C in the long periodic oscillation device ₄Just very electronegative potential, amplifier A ₃Inverting input be electronegative potential, A ₃The in-phase input end current potential equal power circuit DW ₂The voltage stabilizing value in resistance R ₁₄, R ₁₅On partial pressure value (adopt the two-stage mu balanced circuit in the utility model, the first order is for integrated transporting discharging work, and the second level each input end in control circuit provides more stable voltage), this partial pressure value is noble potential, then A with respect to its inverting input ₃The output noble potential, it passes through resistance R on the one hand ₇Be added to comparer A ₁In-phase input end, make A ₁The output noble potential, controllable silicon CR conducting, resistance R is passed through in the work of electric fan energized on the other hand ₁₆The positive and negative A that is fed to ₃In-phase input end, keep A ₃Continue the output noble potential.A ₃The noble potential of output passes through resistance R simultaneously ₁₉With diode D ₃To electrochemical capacitor C ₄Charging, because the utility model is in the long and short period oscillator, amplifier A ₃Inverting input and electrochemical capacitor C ₄Be connected to resistance R between the positive pole ₁₈, at amplifier A ₂Inverting input and electrochemical capacitor C ₃Be connected to resistance R between the positive pole ₁₂C then ₄When being charged to a certain degree, its anodal current potential is in resistance R ₁₈, R ₁₇On partial pressure value surpass A ₃The in-phase input end current potential, so make A ₃Output switching activity is an electronegative potential, at this moment comparer A ₁Output potential by A in the short period oscillator ₂Output potential decision.Work as A ₃During the output electronegative potential, by its positive feedback resistor R ₁₆Effect make A ₃Continue the output electronegative potential, simultaneously C ₄Pass through resistance R ₁₈, R ₁₇C is worked as in discharge over the ground ₄Anodal current potential at R ₁₈, R ₁₇On partial pressure value be lower than A ₃The in-phase input end current potential time, A ₃Recover the output noble potential, so circulation is cyclical variation.The course of work of short period oscillator is identical with the course of work of above-mentioned long periodic oscillation device, and just oscillation period is shorter.So electric fan carries out work, i.e. amplifier A under the acting in conjunction of long and short period oscillator ₂Or A ₃During the output noble potential, comparer A ₁The output noble potential, controllable silicon CR conducting, A is worked as in electric fan energising work ₂, A ₃When exporting electronegative potential simultaneously, then CR ends, and electric fan cuts off the power supply, and finishes the course of work of natural wind simulating.

The utility model detects amplifying circuit owing to inserted temperature control, and its output potential directly has influence on the dutycycle of long and short period oscillator, guarantees that the overall air output of electric fan is directly proportional with environment temperature.(this lower bound temperature can detect potentiometer W in the amplifying circuit by regulating temperature control when environment temperature is higher than the lower bound temperature that the utility model sets ₁Resistance realize), temperature element D ₄(it preferably adopts silicon diode, and because of its cost is low, the temperature variant linearity is good) forward voltage drop reduces, and makes amplifier A ₄Output potential step-down, environment temperature are high more, D ₄Forward voltage drop is low more, A ₄Output potential is also low more, A ₄The electronegative potential of the variation of output passes through resistance R ₂₀And R ₂₁Be added to electrochemical capacitor C in the long and short period oscillator ₄, C ₃Positive pole, C ₄, C ₃Anodal current potential also with being cyclical variation the different oscillation period of its long and short period oscillator, work as C ₄Or C ₃Anodal current potential be higher than A ₄Output potential the time, C ₄Or C ₃Pass through R respectively ₂₀And R ₂₁To A ₄The output terminal discharge makes amplifier A ₃, A ₂The inverting input current potential reduce, then the long and short period oscillator is to C ₄, C ₃Duration of charging lengthening, dutycycle strengthens, i.e. A ₃, A ₂The time lengthening of output noble potential, so electric fan lengthening conduction time, overall air output strengthens.Otherwise overall air output reduces.

When environment temperature is lower than the lower bound temperature that circuit sets, temperature element D ₄Forward voltage drop raises, and makes A ₄The output noble potential, A ₄The noble potential of output passes through R respectively ₂₀, R ₂₁C in the long and short period oscillator ₄, C ₃Charging makes C ₄, C ₃Anodal current potential raise amplifier A then ₃, A ₂All export electronegative potential, so comparer A ₁The output electronegative potential ends controllable silicon CR, and main circuit power cuts off, and electric fan quits work.
