The utility model is timing, pressure regulation, remote control, and the multiple signal control device of consuming device, and it is specially adapted to household electrical appliance, middle-size and small-size industrial electricity apparatus, automatic checkout equipment, scope such as warning automatically.

The present most function singleness of similar control device, and strong slightly its circuit of discrete function is very complicated, debugging is used, and maintenance is all inconvenient, and manufacturing cost is higher.Particularly controlling in advance or automatically of household electrical appliance lacks a kind of function voltage regulator controllers complete and cheap for manufacturing cost at present, at this situation, the utility model constitutes the controller that it has pressure regulation, timing switch, light beam and manual control, fan natural wind simulation and how quick controlled function circuit by several modification functional circuits.The utility model is mainly by forming with the lower part: 1. rectification, filtering, voltage stabilizing circuit; 2. main circuit turning circuit regularly; 3. main circuit open circuit regularly; 4. fan natural wind simulation circuit; 5. gap on-off circuit; 6. light-beam remote control and manual control circuit; 7. how quick control circuit; 8. voltage regulator control circuit.Above circuit is set typical case of the present utility model for by change over switch and is implemented circuit arrangement through assembly as shown in Figure 1.Now as follows to each several part circuit operation division in the enforcement circuit arrangement shown in Figure 1.

1. rectification, filtering, voltage stabilizing circuit as shown in Figure 7, electric main is through step-down, rectification, filtering, voltage stabilizing output two direct voltages, wherein V _DD1Be bidirectional triode thyristor circuits for triggering supply power voltage, and direct current quality factor V preferably _DD2Then as the supply power voltage of other electronic circuit.

Regularly the main power source turning circuit as shown in Figure 8, when energising, V _DD2Pass through K _{The 1b II}, R ₃, W ₁To by C ₄, BG ₁The analog capacitor Ca charging of forming, the voltage Vca on the Ca rises gradually, and Vca is less than the trigger voltage of Schmidt trigger ICa at this moment, so the Ica output HIGH voltage, this voltage is through K _2bIR ₁₁Be added in BG ₄On the base stage, make BG ₄Saturation conduction, then LED ends.Therefore, bidirectional triode thyristor T triggerless voltage, T ends, and then major loop load ZL no-voltage is not worked.Along with the prolongation of time, Vca rises.When the time arrived set point, Vca rose to the trigger voltage more than or equal to Ica, the Ica output LOW voltage, and this voltage passes through K _2bI, R ₁₁Make BG ₄End, then V _DD1Pass through R ₁₂, LED triggers the full conducting of bidirectional triode thyristor T, makes major loop load ZL work, till cutting off the electricity supply, realizes the timing start-up action.The luminous indication silicon controlled of LED working condition.

3. timing main power source open circuit as shown in Figure 9.Vca voltage rises gradually by zero when energized, this moment the Ica output HIGH voltage, this voltage is by D ₅Isolate, simultaneously, the Icf end passes through K for low-voltage _{The 2b II}, R ₁₁Make BG ₄End, so V _DD1Through R ₁₂, LED makes T trigger full conducting, loaded work piece.Along with the prolongation of time, Vca rises, and when reaching setting-up time, Vca is greater than the trigger voltage of Ica, this moment the Ica output LOW voltage, by D ₅Guiding makes Icf upset output HIGH voltage and then makes BG ₄Saturation conduction thus LED end, T triggerless voltage and ending, load quits work.

4. fan natural wind simulation circuit as shown in figure 10.Behind the power connection by R ₅, R ₆, D ₂, C ₅, the square-wave oscillator formed such as Icb produces vibration, its output waveform as shown in Figure 6, T wherein ₁Time period is a high voltage, T ₂Time period is a low-voltage.The voltage of this height alternate passes through K _{The 1d II}, K _{The 2b III}, R ₁₁Make BG ₄Saturated with end V _DD1Pass through R ₁₂, LED ends with full conducting T to hocket, T also can be by K simultaneously _{3 II}, R ₁₃, W ₂, C ₇, D ₈, K _{The 2C III}Phase-shift voltage regulating circuits for triggering assist control Deng forming is in the reciprocation cycle process of full speed → utmost point low speed → full speed fan, reaches the natural wind effect.

5. the gap on-off circuit as shown in figure 11.By K _{The 2a I}, K _{The 1b III}, R ₃, W ₁, C ₄, K _{The 1C III}, R ₄, the square-wave oscillator formed such as Ica produces the output voltage of height alternate through K _{The 2b I}, R ₁₁Make BG ₄Replace saturated with end thereby V _DD1Pass through R ₁₂, LED makes T alternately by reaching the clearance control purpose with full conducting.The control in gap cycle is by W ₁Regulate.

6. light-beam remote control and manual control circuit are as shown in figure 12.During energising by D ₆, D ₇, R ₉, R ₁₀, Ice, Icf, C ₆Deng the rest-set flip-flop of forming at C ₆Effect underlying Q end be low-voltage.This voltage passes through K _{The 2b II}, R ₁₁Make BG ₄End V _DD1Pass through R ₁₂, LED makes the T triggering and conducting, BG is worked as in major loop load ZL work ₂, BG ₃When no light beam shines, BG ₂, BG ₃End, then V _R7, V _RBFor low-voltage and respectively less than the trigger voltage of Icc, Icd, so exporting, Icc, Icd be high voltage, this high voltage is respectively by D ₃, D ₄Isolation does not have influence to the rest-set flip-flop of back.As light beam irradiates at BG ₃When last and light intensity reaches set point, BG ₃Conducting, V _R8For high voltage and greater than the trigger voltage of Icd, make the Icd output LOW voltage, pass through D ₄Guiding and then make thereafter rest-set flip-flop upset, Q holds output HIGH voltage, so BG ₄Conducting, T ends, load quits work realizes light-operated shutdown.The same light beam of working as impinges upon BG ₂When last, circuit makes rest-set flip-flop Q end output LOW voltage, realizes light-operated start.At BG ₂, BG ₃Two ends two groups of buttons in parallel respectively just can realize the manual switch machine.
