description The invention provides a children toy charging fool-proof protection circuit. The children toy charging fool-proof protection circuit comprises an LED lamp LED1 (1), a buzzer LS1 (2), a resistor R1 (3), an NPN triode Q1 (4), a resistor R3 (5), a resistor R2 (6) and an NPN triode Q2 (7). When the insertion direction of a charger is correct, the circuit does not work, does not consume electricity and is in a normal charging state, and when the charger is inserted reversely, the base electrode of the NPN triode Q1 (4) is conducted at a high level, the LED lamp lightens, at the same time, the baseelectrode of the NPN triode Q2 (7) is conducted at a high level, and the buzzer LS1 (2) is electrified to give out buzzing sound to remind a user. Meanwhile, a reversely connected power supply discharges through two loops consisting of the LED lamp LED1 (1), the buzzer LS1 (2), the resistor R1 (3), the NPN triode Q1 (4), the resistor R3 (5), the resistor R2 (6) and the NPN triode Q2 (7), so thatthe safety of a toy circui
