A protection circuit for electric outlet includes: a switch control circuit (101), having input terminals connected to a DC power supply or an AC power supply; an automatic load detection circuit (102), having input terminals connected to the switch control circuit (101) and output terminals connected to output terminals of the outlet for detecting whether a load is connected to the output terminals of the outlet and feeding back a load signal (3) to the switch control circuit (101); and a start button (103), connected to the switch control circuit (101). The load signal (3) and the start button (103) together control whether the switch control circuit (101) should output a high-power and high-voltage AC voltage. The combined use of the automatic load detection circuit (102) and the start button (103) guarantees the safety when a child touches the outlet. |
