[0102] 2. The mains power is protected by a series fuse, equipped with a 200 mA fuse tube. Then through the button-type self-locking switch, the switch has an on-off LED indicator.
[0103] 3. Enter the circuit board, and connect a varistor TVR14561 in parallel to absorb the surge voltage to prevent high voltage and lightning strikes, and play a role in protecting the subsequent circuit.
[0104] 4. Connect a fuse FRV016-240F in series to protect the device from damage when the fault current increases in the subsequent circuit.
[0105] 5. Enter the isolation transformer, which can withstand 4000V voltage and is isolated from the earth to prevent electric shock. Output two sets of voltages, one set provides 9V voltage, and one set provides dual 15V voltages for different circuit needs.
[0106] 6. The dual 15V power supplies are bridge rectified, stabilized, filtered, and protected to supply power to 3 arithmetic units.
[0107] 7. The 9V power supply is bridge rectified, stabilized, filtered, and then connected to a transient suppression diode P6KE36CA. When the two ends of the transient suppression diode are subjected to instantaneous high-energy impact, it can achieve extremely high speed (up to 1*10-12 seconds) to reduce its impedance suddenly, and absorb a large current at the same time, and clamp the voltage between its two ends to a predetermined value, so as to ensure that the subsequent circuit chips are protected from transient high-energy impacts. damage.
[0108] 9. It is stabilized by the integrated voltage stabilizing module LM25758-5.0. This stabilizing block has a large current without an external heat sink. It is directly soldered to the PCB board and filtered to provide power to the subsequent circuit.
[0109] 10. The total waveform generator U16 can generate AC low-frequency basic waves, and can generate modulated AC waveforms according to the treatment needs under the control of the single-chip microcomputer.
[0110] 11. The signal of channel A is moved up by the zero point of the waveform to the digital potentiometer X9C103S1, which controls the intensity of treatment under the control of the single-chip microcomputer.
[0111] 12. The operational amplifier is an energy conversion device combined with a step-up transformer to provide sufficient therapeutic energy as required. The output is controlled by the relay, and the B road and C road are the same as above.
[0112] 13. The output signal passes through the signal detection circuit of the optocoupler combination to provide the single-chip microcomputer with tank drop information.
[0113] 14. Through the current detection circuit, the current information during treatment is provided to the single-chip microcomputer to deal with when the current exceeds the limit.
[0114] 15. The current transformer is a conversion device for three-channel therapeutic current, which can perform combined detection of single-channel, two-channel, three-channel, and current.
[0115] 16. There is also a current setting adjustment circuit and a current setting limit circuit. Overcurrent protection circuit FRV005-240F during output. Program sintering serial port and protection circuit.
[0116] 17. The remote control module and control port, the remote control adopts a superheterodyne sound meter frequency stabilization circuit, which works stably.
[0117] 18. Intensity control adopts encoder mode, with single-chip microcomputer control, which makes the knob unlimited and adjustable speed.
[0118] 19. Waveform control input port circuit. Perform waveform output control.
[0119] 20. The voice prompt circuit provides voice prompts on the working status of the treatment device.
[0120] 22. Single-chip IAP15W413S, to control the functions of the whole machine.
[0121] Turn on the power switch, the power indicator light is on, the single-chip microcomputer starts to run, the display screen is on, and the treatment time is ten minutes, and the time is still. The ABC three-way intensity bar is displayed as zero, and the Lojo icon is displayed, which will always be displayed in the future. Display treatment mode: continuous, with a long tone prompt.
[0122] When the intensity knob is rotated, the display bar segment is correspondingly displayed, the relay is closed, the treatment time countdown starts to display, and a prompt sound is emitted. The remote control has the same function as the knob.
