Description

Pen capable of adding ink

Technical Field

The invention relates to a pen, in particular to a pen capable of adding ink.

Background

The pen is a common writing tool, generally divided into a pen, a pencil, a ball-point pen and the like, wherein the ball-point pen is further divided into an oil ball-point pen, a gel ink pen and a water pen, the different names are also called as a ball-point pen, a sign pen, a ball-point pen and the like, the common disposable refill of the gel ink pen is generally composed of an ink tube and a pen point, the tail part of the ink tube can be filled with lithium-based ester for sealing the ink and not influencing the balance between the ink cavity and the external pressure, in addition, a fin type structure is adopted for carrying out air exchange between the ink cavity and the outside for balancing the internal pressure and the external pressure, the writing principle is that the ball in the pen point rolls on a writing medium by the dead weight of the ink or the ink in the ink tube, the ink or the ink in the ink tube is uniformly coated on the writing medium by the ball-point ball, and the ball-point pen needs the rolling of the ball and, The ball-point pen and the like cannot write normally under the conditions of no gravity and small friction of writing media, such as on a glass or smooth plastic sheet; when in use, the pen point can be blocked and is difficult to treat due to the influence of ink and writing medium, and the pen point is usually a scrapped pen core; at present, most refills of gel-ink pens and ball-point pens are disposable, and the design of ink filling is not adopted, so that the risk of environmental pollution is increased if the disposable refills discarded after the ink is used up cannot be properly treated.
