[0002] A fluorescent pen is a pen used for marking. It uses thicker and lighter ink to cover key areas for marking. The key principle of ultraviolet fluorescent ink is to add visible fluorescent compounds that are excited by ultraviolet rays into the ink. By absorbing light energy, the energy level transition of atoms is generated, and then the extra energy absorbed is released. After marking, the text is clearly visible without blocking it. The fluorescent pen contains fluorescent agent, which will produce a fluorescent effect when encountering ultraviolet rays, emitting white light, so that the color looks like a dazzling fluorescent feeling. It is often used in office and study.
[0003] When the ink in the liquid storage cotton core of the existing fluorescent pen is used up, the fluorescent pen is often directly discarded, and pigment cannot be injected into the fluorescent pen, the service life is short, and the ink on the pen head of the fluorescent pen becomes dry and adheres to the pen tip, so that writing cannot be done when writing again, and the ink cannot be supplied quickly.
