Self-priming circulating ink storage eco-friendly pen based on capillary and siphon action

Abstract

The invention discloses a self-absorbing liquid circulating ink storage environment-friendly pen based on capillary and siphon effects, which includes a pen holder and a pen head. The pen holder includes a pen holder shell, a capillary liquid-absorbing core, an ink bag tube and a siphon tube, and the ink bag tube is located in the pen holder shell , the capillary liquid core is filled between the pen barrel shell and the ink bag tube, the front end of the capillary liquid core is located at the front end of the pen shell, the rear end of the capillary liquid core is connected with the high liquid level end of the siphon tube, and the low liquid level end of the siphon tube Connect to the rear end of the ink bladder tube. The invention utilizes capillary action and siphon action to automatically transfer ink into the ink sac tube, which is convenient for ink filling, and the amount of ink filling can be better controlled, and the amount of ink filling is large, which solves the problem of existing gel pens that can refill ink The technical problem that requires manual ink filling; and it uses water-absorbing fibers to introduce ink into the nib, and the nib uses balls to transfer the ink to the paper, avoiding the nib of the pen nib that is too hard and easy to scratch the paper and the nib of the pen. The increase of the ink outlet gap leads to the technical problem of excessive ink output.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a pen. Background technique [0002] Fountain pens and gel pens are the two most used pens for writing in the world at present. However, both fountain pens and gel pens have their corresponding disadvantages: the nib of the pen is relatively hard, and it is easy to scratch the paper; The main structural material of the fountain pen is metal, which is heavy and expensive, so there are many inconveniences. The refills of gel pens are basically disposable refills, which will be discarded after one use, which will cause a lot of waste of refill materials. And burying plastic waste such as gel refill shells will cause great harm to the environment.

Problems solved by technology

However, both fountain pens and gel pens have their corresponding disadvantages: the nib of the pen is relatively hard, and it is easy to scratch the paper; The main structural material of the fountain pen is metal, which is heavy and expensive, so there are many inconveniences

The refills of gel pens are basically disposable refills, which will be discarded after one use, which will cause a lot of waste of refill materials. And burying gel refill shells and other plastic waste will cause great harm to the environment

[0003] Although the existing straight-liquid rollerball pens are more popular in the market, they have the problems of inconvenient ink replacement and waste of ink in the pen shell, and the cost is higher; It still needs manual ink filling and the ink absorption is limited, which is very inconvenient to use
