Gel pen based on solar illumination

Abstract

A gel pen based on solar illumination solves the problems that a pen refill of an existing gel pen is too small in capacity, the pen refill capacity increasing manner is singular, and the existing gel pen is not provided with a built-in auxiliary light source under the condition that brightness is low. The gel pen based on solar illumination is mainly characterized in that a pen refill is spiral, the length of the pen refill can be increased through the spiral shape, and therefore the capacity and the volume are increased; a pen tail is composed of a small cylinder and a spherical solar cell, and the small cylinder is a carrier of the spherical solar cell; the spherical solar cell of the pen tail is connected to the position of a switch of a pen body and then connected to an LED lamp at the position of a conical pen point through conductive silver adhesives, and when a miniature button is pressed, the spherical solar cell achieves conversion from optical energy to electric energy, and the annular LED lamp can be brightened up; the pen point is rotationally connected with the pen body, and the small cylinder of the pen tail is also rotationally connected with the pen body; and when the pen is not used, a pen cap is installed on the pen, the pen refill is protected through a rubber groove, and the annular solar cell can be charged and store electricity.

Description

technical field [0001] The invention relates to gel pens, in particular to the field of gel pens based on solar lighting. Background technique [0002] In the field of gel pens, gel pens generally have a small refill capacity, a single way to increase the capacity and volume, a fast replacement frequency, and cannot write normally under low brightness conditions. These information are mainly obtained through patent search, online product novelty search and existing product information in the market, which makes this patent application possible. Contents of the invention [0003] The purpose of this design is to provide a gel pen based on solar lighting in order to overcome the above-mentioned defects of the existing gel pen. [0004] Technical solutions: [0005] This design is made of pen core, pen tail, nib, pen body, pen cap. The pen core is helical, and the pen core can increase the length through the helical shape to increase the capacity volume; the pen tail is co...
