ABSTRACT:
A waterproof flashlight device for umbrellas comprises a shell made of transparent soft material, a circuit board, at least a battery, and a self-control switch. The shell has a seat installed inside. The seat is joined with a stage having a hollow chamber inside through a waterproof grommet. The circuit board is installed inside the stage. The flashlight circuit on the circuit board connects to at least a battery. The self-control switch connects the battery with the flashlight circuit. The self-control switch has two soft circuit boards. A metal ball is lapped on one of the two soft circuit boards. When the user unfolds the umbrella at night, the metal ball will contact the two soft circuit boards, and the battery will provide electricity to the flashlight circuit. The flashlight circuit will thus flash when there is no sufficient light outside.
