Abstract

The utility model relates to a voltage regulating switch, which utilizes human-body touch as a control signal. Through the variation of the touch electrode when checking the human-body capacitance, and by converting the variation into a voltage regulating signal to regulate the voltage through a special touch circuit, the apparatus and the touch electrode are provided with strong anti-interference ability. Because the voltage regulating switch apparatus breaks through the conventionally adopted inductance voltage regulating mode, the voltage regulating switch consumes little few energy itself; therefore, the touch type, energy saving voltage regulating switch has an energy saving effect.

Description

Touch type, energy saving voltage regulating switch

It is the voltage-regulating switch unit of control signal with the human body touch that the utility model relates to a kind of.

The at present popular contact witch pair touch electrodes that adopt utilize the conductivity of human body to be switching signal, or adopt single touch electrode more, utilize human body institute static electrification as switching signal.The problem that exists is that the former touches inconvenience, and latter's poor anti jamming capability is difficult to be applied on the regulator of ac electric apparatus.

The purpose of this utility model is that providing a kind of to the public is that control signal is regulated incandescent lamp with the touch, fans etc. are with the voltage tap changer on the electric loading, and adopt single touch electrode, utilize body capacitance to be induced signal, it is convenient that this switch is touched, and antijamming capability is strong.

Specific implementation of the present utility model can give to describe in detail with reference to accompanying drawing.

Figure (1) is an electrical schematic diagram of the present utility model.

Shown in figure (1), this voltage-regulating switch unit is by touch electrode Y, touches circuit 1, control circuit 2, and switching circuit 3, power circuit 4 constitutes.RL uses electric loading among the figure, can be alternating current machines such as electric fan or incandescent lamp etc.Touch circuit 1 and the touch signal of touch electrode Y is converted human body to signal input end that a control signal is received control circuit 2.

Control circuit 2 is with the input of the not gate F4 signal input end as this circuit, the control signal that touches circuit 1 is received on the sub-CP of clock pulse input terminal of IC2 after by the F4 shaping, according to the control signal of receiving, deposited Pyatyi pressure regulation state with circuit, and under by the synchronizing signal effect that inserts from switching circuit 3 by D10, work, export the controlled terminal that a switching signal is received switching circuit 3 by C8, to control its angle of flow or switch.

Switching circuit 3 is received its controlled terminal with the switching signal of control circuit 2 outputs, i.e. the control utmost point of controllable silicon K1.Two ac terminals of rectifier with AC power, are connected into a series connection loop with electric loading RL as two switch main terminals of this circuit.This circuit is regulated the average voltage with electric loading RL two ends under the effect of switching signal, or controls the break-make of its power supply.

Power circuit 4 provides dc power supply about 6 volts for device.

In touching circuit 1, F1 is the not gate of a band application schmitt trigger.With F1, R1, C1 is connected into square-wave oscillator, the output of F1 is by R2, and the input that R3 polyphone loop and D1 receive F2 meets a capacitor C2 over the ground, and the input of not gate F3 is received in the output of F2, and receive C5 again by D3, the R5 parallel network, touch electrode Y receives R2 by capacitor C3, the tie point of R3, by F3, D2, the feedback network that C4, R4 are connected into receive the input of F1 by R4.The operation principle of this circuit is as follows: when human body did not contact touch electrode Y, the square wave of F1 output was by R1, R2, R3, D1 discharges and recharges to C2, thereby has formed the trapezoidal wave with following pinnacle at the input of F2, makes F2 export a series of burst pulses, pass through F3, D2, C4, the feedback network that R4 forms, controlled the duty ratio of F1 output square wave, the pinnacle is a little less than the off level of F2 under the trapezoidal wave of assurance F2 input.When human body contacts touch electrode Y, just be equivalent to body capacitance and inserted circuit, this will weaken the velocity of discharge of C2, make the following pinnacle of F2 input trapezoidal wave be higher than its off level, thereby make the F2 output low level, i.e. no pulse input, C5 will discharge into zero volt by R5.After human body left touch electrode or arrives by the feedback time that feedback network determined, F2 recovered to export a series of spikes again, and C5 is charged to high level again.Thereby converted touching each time of human body to C5 and gone up the process of voltage single step of releasing charging, as the control signal output of this circuit.Each parameter tuning principle is as follows in the circuit: adjust R1 or C1 and make the cycle of oscillation of F1 at (1-100) VS, adjusting R5 and C5 makes the time constant of its decision be (0.1-2) S, adjust R3, R2 or C2 make F2 can import a series of spikes, R2 generally gets (1-10) kilo-ohm, C3 generally gets about 500PF, adjusts R4 or C4 and makes the time constant of its decision be (0.2-10) S.

In control circuit 2,2C2 adopts integrated circuit CD4022, is one counter/pulsqe distributor, and has been connected into senary form.Also can adopt the counter of other form, and can be connected into the pressure regulation of the realization any number of stages of arbitrary carry system as required.In power circuit 4, D12, R13 series connection.The two ends in a loop capacitor C10 in parallel can make 1 pair of human body touch induction of touch circuit sensitiveer.

This installs used not gate F1-F6, adopts integrated circuit CD40106.

Single touch electrode of this device can be by drawing with lead in the circuit.Make control convenient, flexible, because what touch that circuit 1 detects is the capacitance variations of human body with respect to touch electrode, static exchanges to disturb to wait and will can not make the touch circuit erroneous action, consolidates device and touch electrode and has very strong antijamming capability.

Because this tap changer has been broken through the conventional inductance type voltage regulating mode that is adopted, itself consumes energy hardly, Gu this has energy-saving effect.
