The present invention implements like this: electric current through being defeated by a slice dual time-base ic and 1 transistor, 5 resistance, 4 capacitors behind the power circuit and forming modulation pulse generator and the scanning frequency pulse generator after the electronic circuit formed through power output amplifier section again, what make generation is a kind of instrument with low-frequency pulse modulated medium frequency swept continuous wave spectrum.
Be described in detail enforcement of the present invention below in conjunction with accompanying drawing:
Fig. 1. circuit connection diagram of the present invention.
Fig. 2. user mode figure of the present invention.
See Fig. 1. power circuit of the present invention partly is made up of a power supply V, on and off switch K3, light emitting diode D2, resistance R 11, electrochemical capacitor C6, capacitor C 7, the positive pole of power supply V connects K switch 3, forms parallel circuit with electrochemical capacitor C6, capacitor C 7, K switch 3 behind the negative pole of the negative pole sending and receiving optical diode D2 of power supply V, the series resistance R11.Also can form with a kind of two-supply circuit as prior art, but this two-supply circuit need be with one 9 volts battery, another is 3 volts a battery, so inconvenience when using, power consumption are big, and can't use alternating current, and with the battery that behind the power circuit of the present invention can be 3 ± 0.4 volts with DC voltage, easy to use, also can after using commutator, connect the power supply of alternating current with 220 volts of voltages by socket J2.
Modulation pulse generator of the present invention and scanning frequency pulse generator are that a slice dual time-base ic ICM7556 is arranged, 1 transistor T 1,5 resistance R 2--R6,4 capacitor C 1--C4 form, electric current through power circuit output connects dual time-base ic, its 1 foot and resistance R 2, R3 one end connects, 6 feet connect behind 2 feet positive pole with resistance R 3 other ends and electrochemical capacitor C1, the base stage of transistor T 1 connects, 3 feet are connected with an end of capacitor C 2, the negative pole of 7 feet and electrochemical capacitor C1, the other end of capacitor C 2, C3, the end of C4, the colelctor electrode of transistor T 1 connects, 5 feet are connected with 10,4 feet and 14 connect and with resistance R 2 other ends and R4, the end of R5 connects, the other end of resistance R 4 is connected with transistor T 1 emitter stage, 13 feet connect the other end of resistance R 5 and connect the end of R6,8 feet are connected 12 feet and are connected resistance R 6 and capacitor C 4,11 feet connect the common point of K switch 2, connect the power output amplifier behind the 9 foot connecting resistance R7.
Dual time base circuit be except with also can selecting the ICM556 type for use the above-mentioned ICM7556 type, but its resistance, electric capacity also need be done corresponding adjustment, and there are the big shortcomings of power supply, power consumption that need with more than 4.5 volts in it.Because ICM7556 has series of advantages such as input impedance height, power consumption is little, the good power supply subject range of effect is wide in the cmos circuit, be specially adapted to occasions such as low-power consumption, so the present invention selects the ICM7556 dual time-base ic for use, it contains two identical time base circuits.The model of transistor T 1 can be selected D965,9013,9014,9018,8050 etc. for use.In order to be the best with supporting 9015 types of selecting for use of ICM7556.
The 1-7 foot of ICM7556 is time base circuit I, with resistance R 2-R4, capacitor C 1-C3 and transistor T 1 are formed pulse generator and are produced rectangular wave at the 5th foot, its frequency is the low frequency of 3Hz, the 10th foot of the time base circuit II of the 8-13 foot of (size of its frequency is by the resistance R of selecting 2, R3 and capacitor C 1 decision) modulation ICM7556.And capacitor C 1 two ends being discharged and recharged behind the signal isolated converter one of output and the corresponding triangular wave of modulating pulse by transistor T 1, modulation voltage removes to select to control the 11st foot of another time base circuit II.By time base circuit II (the 8-13 foot of ICM75566) and resistance R 5, R6, capacitor C 4 is formed the scanning frequency pulse generators.Because its forced resetting end is controlled by the output square-wave pulse of time base circuit I, so time base circuit II only just may work in the output pulse high level time of time base circuit I, again because its control end Vc is controlled by the triangular wave of transistor T 1 output, controlled by the triangular wave of T1 output so time base circuit II makes the stage output pulse frequency, will between frequency sweep wave spectrum upper bound frequency and frequency sweep wave spectrum lower bound frequency, do the automatic frequency sweep conversion.The center of its frequency sweep is by selected resistance R 5, R6 and capacitor C 4 decisions.Because the triangular wave of the output of T1 is corresponding with the square wave of time base circuit I, so general's automatic frequency sweep from low to high is once in a working time in the output pulse of time base circuit II.
Then can make speed governing usefulness as in this circuit, increasing resistance R 1 and K switch (see figure 1) again.
Power output amplifier part of the present invention is by two transistor Ts 2 and T3, and two resistance R 7, R8 and potentiometer W, capacitor C 5 and coupling transformer B form.By the wave spectrum of time base amplifying circuit 9 feet output after resistance R 7 connects potentiometer W connecting resistance R8, connect transistor T 3 emitter stages, the common point of potentiometer W connects the base stage of transistor T2, the emitter stage of T2 is connected the T2 colelctor electrode and connects the first end that meets coupling transformer B behind the T3 colelctor electrode with the base stage of T3, capacitor C 5 and transformator B form in parallel, and the secondary end of transformator B directly outputs to output plughole J1 after with resistance R 9 parallel connections.By this power amplification circuit, the synthetic scanning frequency pulse that is subjected to that time base circuit II the 9th foot is produced carries out power amplification, and exports to therapeutic electrode by output plughole J1.In this circuit, also can select for use a diode to replace transistor, as long as its resistance and electric capacity are done corresponding the adjustment.
