Disclosed are a power-loss delay circuit and a detection control circuit thereof. The power-loss delay circuit and the corresponding detection control circuit are added onto a flyback circuit. When a product is working normally, an energy storage capacitor is charged, and when an input power supply of the product is cut off, the detection control circuit detects that an input voltage of the product drops to a set value and triggers the control circuit to drive a switch transistor to be turned on, so that the energy of an energy storage capacitor is released, thereby keeping the product working continuously for a period of time. The power-loss delay circuit and the detection control circuit thereof have no effect on the normal working state of the product. When the input power is cut off, capacitance stored in an external capacitor is introduced in time to keep the product working continuously.
