[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.
