A_SENS1 and A_SENS2 is MCU output control terminals in embodiment, when A_SENS1 exports low, A_SENS2 output height
When, triode Q1 cut-offs, Q4 conductings；Q7 base earth triode ONs, due to Q4 grounded collectors, Q3 cut-offs, Q5 conductings；By
End in Q1, Q1 current collections are extremely high, Q6 cut-offs, but since Q5 is connected, and Q2 base stages are height, Q2 conductings；Pulse current direction at this time

Pole is grounded, Q6 conductings, Q2 cut-offs, Q8 conductings, and Q3 base stages are height, and Q3 conductings, since Q4 ends, Q7 cut-offs, Q5 ends, due to Q5
Cut-off, Q2 end, at this time current direction HT → Q6 → A1 → R9 → A2 → Q3 → D3.
If at this time when two electrode sheet resistances of the SA1 in load monitoring circuit diagram and SA2, i.e., not over electrode slice with
Human skin contacts, and forms resistance and, since R9 has 1M ohm, is significantly limited then the resistance at the both ends A1 and A2 only has R9
The electric current flowed through, so the same phase follower output constituted eventually by LMV4324 (U1) is also low level.But MCU is detected
When exporting low level to LEC_REGUL, that is, think that equipment is not using, closes output.
When VAL_ELECTRODES_A is high level, Q11 conductings, while SA1 and SA2 pass through electrode slice and skin contact
When having resistance, triode Q9, Q10 conducting, the electric current for flowing through A1 and A2 becomes larger, and connects with R17 partial pressure through R14, R15, R16,
Amplifier in-phase end forms high level, and VAL_ELECTRODES_A feeds back to MCU, and MCU detects high level, adjusts output power.
When VAL_ELECTRODES_A is low, Q11, Q9, Q10 cut-off, will not even if there is human body resistance access at this time
Output power.
A kind of electronic pulse masseur with security protection detection function provided in this embodiment, passes through MCU system, H
