Description

Slow writing pen

Technical Field

The utility model relates to a writing tools technical field specifically needs to say, especially relates to a pen writes at a slow speed.

Background

The existing ink-supply writing tools such as marking pens, white board pens, highlighters and the like generally adopt a wrapped core or a cotton tube as an ink storage medium, and the ink storage medium generally has the following disadvantages: firstly, the ink stored by using a coiled core or a cotton tube as an ink storage medium is very limited; secondly, the writing tool using the coiled core or the cotton tube as the ink storage medium continuously writes in the writing process, the ink output per writing length is gradually reduced, and the written handwriting is gradually faded; another disadvantage is that thirty percent or more ink typically remains in the wrap or cotton tube even when writing quality is significantly degraded and difficult to use. Thus, such writing instruments tend to be inexpensive, but are wasteful.

The gel pen ink supply with the largest use rate adopts the organic solvent, the viscosity of the organic solvent is lower than that of oil pen ink and is thicker than that of water pen ink, when writing, the ink is converted into liquid ink from a semi-solid state through a pen point, and the gel pen ink has the advantage that each drop of ink is used on the pen point and cannot volatilize or leak water, so that smooth writing feeling can be provided, and the ink flow is smooth and stable. However, the writing effect of the writing brush is too smooth, so that the writing speed of people is faster and faster, and the people are more and more free.

The traditional pen is also called a fountain pen, and the ink is prepared by mixing water-soluble ink powder. The user has mostly the feeling of writing, or has higher requirement to write experience sense, therefore the urgent need is an independently controlled ink flow, instrument that can write at a slow speed, let them fully experience the enjoyment of writing after slowing down.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem that ink flow is difficult to control among the prior art, the utility model aims to provide a pen is write at a slow speed, through the gasbag that the extrusion setting was held at the pen, let the person of writing adjust out the china ink volume by oneself, realize adjusting the purpose of ink flow, reach the effect that forces to slow down writing speed.

In order to achieve the purpose, the technical scheme of the utility model is that what realize like this, a write pen at a slow speed, hold and pass through connecting portion with the china ink bag including the pen, the pen is held and is connected with the china ink bag, and the pen is held and is provided with the gasbag in, and the gasbag passes through the capillary and is connected with the china ink bag.

Further, the pen holder further comprises a cavity, the cavity is connected with the pen holder through a connecting portion, and the ink bag is arranged in the cavity.

Further, an inking piston is arranged in the cavity.

Preferably, the number of air bags is two.

Further, the connecting portion are provided with external threads, and the connecting portion are connected with the pen shell through a spiral structure.

Implement the utility model discloses the beneficial effect who brings is:

the air bag arranged in the pen holder is extruded, so that a writer can adjust the ink output by himself, the purpose of adjusting the ink flow is achieved, the effect of forcibly slowing down the writing speed is achieved, and the problem of different writing depths caused by more or less ink can be prevented.
