Tap water ball refill pen

Abstract

The invention discloses a tap water ball refill pen. The tap water ball refill pen comprises a tapered pen nib, an iridium grain ball, an outer micropore, a tapered sleeve of the tapered pen nib, a capillary tube, a water guide refill inserting port, a water guide refill, an intermediate body, a water guide sleeve cavity, a nib protection tapered sleeve, a water guide sleeve, a tapered pen nib inserting head, a water guide cavity, a water guide cavity hair crack, an air return groove, an ink bag connecting sleeve, an ink bag, a pen holder and a pen cap. The tap water ball refill pen is characterized in that the iridium grain ball is welded at the top end of the tapered pen nib, and is connected with the top end of the tapered pen nib through the tapered pen nib, the outer micropore, the tapered sleeve of the tapered pen nib, the capillary tube, the water guide refill inserting port, the water guide refill, the nib protection tapered sleeve, the intermediate body, the water guide sleeve, the tapered pen nib inserting head, the water guide cavity, the water guide cavity hair crack, the air return groove, the ink bag connecting sleeve, the ink bag and the pen holder. The tap water ball refill pen can be used for writing in any direction with cleanness, is durable, can be used for writing in an easy and fluent style by a user, and has a flush tip and extremely excellent handfeel in writing.

Description

technical field [0001] The invention relates to a water-based ink pen, in particular to a fountain pen with a ball core. Background technique [0002] As we all know, fountain pens and ballpoint pens are the two most widely used writing instruments at home and abroad. Pens occupy part of the market because of their better writing effect and longer service life, while ballpoint pens occupy part of the market because of their low price and easy to write. However, the nibs of the current fountain pens are easy to break, and they must be directional when writing. Otherwise, the writing effect is not good, and there is a phenomenon of scratching the paper; while the writing effect of the ballpoint pen is poor (including the current gel pen), and the writing is easy to slip and lacks the tip. Simultaneously also often have the situation of broken Chinese ink phenomenon to occur, therefore, there is always bigger deficiency in present writing instrument, and it is better to develop...

Simultaneously also often have the situation of broken Chinese ink phenomenon to occur, therefore, there is always bigger deficiency in present writing instrument, and it is better to develop a kind of writing effect, long service life, easy to use, the advanced writing instrument of environmental protection seems very urgent, and has Larger market prospects
