Gel pen core cleaning device

Abstract

The invention provides a gel pen core cleaning device. A thread connecting rod 2 is driven by a screw cap 1. An extensible rod 3 is adjusted by the thread connecting rod 2 and pushes a spring 4. The spring 4 pushes a piston 5 through elastic force. The piston 5 slowly exerts pressure to ink so that the ink in the pen core can be used up.

Description

technical field [0001] The invention relates to a writing implement. Specifically, it is a core cleaning device that can use up the ink in the pen core. Background technique [0002] In today's gel pens, it is generally difficult to use up all the ink in the refill, which not only wastes resources, pollutes the environment, but also annoys users. Contents of the invention [0003] The invention provides an ink pressurizing device for a neutral pen, which can effectively drain the ink in the pen core. [0004] The adopted technical solution is: the screw cap pushes the threaded connecting rod to adjust the telescopic rod, the telescopic rod pushes the spring, the elastic force of the spring pushes the piston, and the piston exerts pressure on the ink. [0005] The invention has the beneficial effects of fluent writing, reducing ink waste and reducing people's troubles. Description of drawings [0006] The present invention will be further described below in conjunction...
