Glow stick emitting light automatically when shaken

Abstract

The invention relates to a shaking self-luminous luminous rod, which comprises an outer layer transparent ring, a middle layer spacer ring, an inner layer ring, a coil copper wire, a guide piece, a sealing piece, a magnet, a wire, a light-emitting component and a copper wire coil contact, and the outer layer The transparent circle surrounds the middle spacer, the middle spacer surrounds the inner circle, the outer transparent circle and the middle spacer form a light-emitting area, the middle spacer and the inner circle form a coil area, and the inner circle forms an active area. The end is connected to the guide piece through the copper wire coil contact, and the light-emitting part is connected to the guide piece through the wire; when the rod body is swung, the magnet in the active area performs centrifugal motion, so that the magnetic flux of the copper wire coil wrapped in the coil area changes, and the change of the magnetic field generates an electric field. , so that the copper wire coil generates current, so that the light-emitting parts connected to the guide strips emit light, avoiding the shortcomings of traditional chemical fluorescent sticks and button battery light-emitting sticks that can only be used once, have a short service life, and waste resources, and can be used as physical The teaching aids for magnetism and electricity are very interesting.

Description

technical field [0001] The invention relates to a luminous stick device, in particular, a shaking self-luminous luminous stick. Background technique [0002] The existing chemical fluorescent stick is composed of a thin plastic tube and the liquid in the tube, and the chemical reaction is used to make the substance in the tube obtain the ability to temporarily fluoresce; the button battery light stick is composed of the stick handle (built-in control circuit) and the stick body (light emitting small light string) , using simple circuits (or control chips) and glass tubes to achieve the purpose of lighting; they can only be used once, have a short service life, and waste resources. [0003] Therefore, it is necessary to design a luminous stick that can be used repeatedly and has a long life. Contents of the invention [0004] The object of the present invention is to provide a shaking self-luminous light stick, which avoids the shortcomings of traditional chemical light st...
