Core Functions of the DC Socket on the Water Gun PCBA

1. External Charging and Power Supply: Serves as the DC power input interface to connect chargers for charging the built-in lithium battery. In certain modes, it can also directly drive the water pump using an external power source.

2. Automatic Power Switching: Integrated internal switch contacts automatically disconnect battery power when the DC plug is inserted, switching to external power supply to prevent damage from simultaneous battery and adapter charging.

3. Polarity and Anti-misinsertion Design: Specific aperture and structural features prevent reverse insertion, avoiding circuit burnout caused by incorrect polarity connection.
