Gel ink pen refill capable of being recycled

Abstract

The recyclable gel ink pen refill comprises a first pen refill tube, one end of the first pen refill tube is movably connected with a second pen refill tube, a pen point is movably connected to the end, away from the second pen refill tube, of the first pen refill tube in an inserted mode, and a negative pressure assembly is movably arranged at the end, away from the first pen refill tube, of the second pen refill tube. The end, away from the negative pressure assembly, of the second refill tube is placed in ink, a driving plate is pressed to drive a corrugated tube and a damping spring to be compressed, air in the corrugated tube is discharged through a second one-way valve, and the driving plate is loosened to drive the negative pressure assembly to rotate under the action of the damping spring. Air in the second refill tube enters the inner wall of the corrugated tube through the first one-way valve, ink is sucked into the second refill tube, the operation is repeated for several times until the second refill tube is filled with the ink, and the second refill tube and the first refill tube are connected through the connecting tube and the connecting groove again; therefore, the purpose of conveniently recycling the second refill tube is achieved.

Description

technical field [0001] The invention relates to the technical field of refills, in particular to a recyclable gel refill. Background technique [0002] As a writing tool, the pen core is widely used in daily life, study, and office. The general pen core includes a pen core tube and a pen core head. The pen core tube and the pen core head are connected by threads. The pen core tube is equipped with a writing For the liquid used, the head of the refill is equipped with a steel ball. When writing, the liquid in the refill tube slowly flows out through the steel ball at the front end of the refill head to achieve the purpose of writing. [0003] But prior art is in actual use, gel pen adopts ink as writing material, and the use speed of the ink in the pen core is very fast, when the nib has not reached its service life far away, there is no ink to write in the pen core, and Therefore core has to be changed or inject ink again, has both wasted limited earth resources to change p...

Problems solved by technology

[0003] But prior art is in actual use, gel pen adopts ink as writing material, and the use speed of the ink in the pen core is very fast, when the nib has not reached its service life far away, there is no ink to write in the pen core, and Therefore, the core has to be replaced or re-injected with ink. Changing the pen core has both wasted limited earth resources, increased the pollution of the environment and increased the user's operating costs.
