The 220 V mains electricity is connected to the closed power switch SB, resistors R1, R2, and potentiometer RP to form a voltage divider circuit, and the capacitor C3 is charged after the voltage is divided. When C3 is charged to a certain value, the bidirectional diode VD5 is turned on, and a trigger pulse voltage is output to the trigger pole of the bidirectional thyristor VS. VS is triggered to turn on, and the output end outputs a controlled pulsating DC voltage to power the DC motor M. The motor M rotates under the power, driving the massage head to perform massage movements. Changing the resistance value of the potentiometer RP, that is, changing the charging time constant of C3, is actually changing the conduction angle of the bidirectional thyristor VS to achieve the speed regulation of the DC motor M.
