Straight liquid type water isolator

Abstract

The invention provides a straight liquid type water isolator. The straight liquid type water isolator comprises an outer circular wall, a bottom circular wall, a plurality of parallel water isolation layers and a connecting column. At least one groove is formed in the surface of the connecting column. The water isolation layers are arranged between the outer circular wall and the bottom circular wall. The connecting column is connected with the outer circular wall and the bottom circular wall and penetrates the multiple water isolation layers. An ink storage structure formed by the straight liquid type water isolator divides ink layer by layer. Compared with a roll-packing core ink storage structure, the straight liquid type water isolator is more stable and more superior in performance. According to a gel pen with the straight liquid type water isolator, the ink filling amount can be increased multiply, the writing length of the product can be greatly increased, all indexes are higher than the requirements of the national standard and the industry standard, and writing with the product is stable all the time.

Description

technical field [0001] The invention relates to the field of writing instruments, in particular to a straight liquid water trap for water-based pens. Background technique [0002] There are many water-based writing products, such as marker pens, highlighters, and whiteboard markers for daily use. However, most of these water-based pens are of roll core structure and written with fiber tip. [0003] The ink supply structure of the roll-wrapped core, the storage of ink is absorbed by the gap density of the fiber in the roll-wrapped core. This kind of water-based pen with a core-wrapped structure has certain limitations when writing, and mainly has the following defects: [0004] 1. The supply of ink is very slow; [0005] 2. The roll core itself has the function of absorbing ink, the residual amount of ink is large, the utilization rate is low, and the storage and service life of the pen are relatively short; [0006] 3. The volume of ink stored in the roll core is small, ...

AI Technical Summary

Problems solved by technology

[0004] 1. The supply of ink is very slow;

[0005] 2. The roll core itself has the function of absorbing ink, the residual amount of ink is large, the utilization rate is low, and the storage and service life of the pen are relatively short;

[0006] 3. The volume of ink stored in the roll core is small, and it is easy to evaporate, so that the writing length of this type of water-based pen is relatively short, and rarely exceeds 100 meters;

[0007] 4. The ink storage volume of the roll core is too full, and it is easy to cause ink leakage, and the negative pressure and high temperature tests are often unqualified
