<p>A control circuit for an electronic cigarette box and a control method therefor. The control circuit has a charging management module (100), a built-in battery (300), a control module (200), a boosting module (400), a battery voltage detection module (600), a load detection module (900) and an indication module (800). According to a battery voltage signal detected by the battery voltage detection module (600), a load detection signal detected by the load detection module (900) and a battery charging signal sent by the charging management module, the control module (200) controls the boosting module (400) to adjust a charging voltage provided by the charging management module or the built-in battery and charge a charging load, and at the same time controls the indication module (800) to display a charging state and provide indications for various working states or abnormal states, and there are a wide variety of charging interfaces, and charging plugging detection and charging unplugging detection functions are provided, and the built-in battery is protected in a charging process, and the control circuit also has an output short-circuit protection function.</p> |
