Description

Writing instrument blotter and writing instrument

Technical Field

The utility model relates to a belong to daily study article technical field, specifically, provide a writing instrument blotter, still provide the writing instrument who adopts this blotter.

Background

The invention discloses a simple pen capable of continuously absorbing ink, which is a patent case CN113085408A, and provides a brand new ink absorption mode for the pen, and has the advantages of convenience in ink absorption and large ink capacity. Subsequent studies on CN113085408A, a simple pen with continuous ink absorption, have found that the pen has two additional advantages: the ink bottle has the functions of ink-foam separation and gas-liquid shunting, and can suck residual ink in the ink bottle. When the ink in the ink bottle is less, the existing pen usually can suck a large amount of foam, and the sucked foam is not easy to break in the ink cavity and cannot be fully sucked; when the amount of residual ink is very small, the ink does not absorb at all. The pen can absorb very little residual ink as long as a small amount of ink is left in the pen tongue before ink is absorbed. The ink is difficult to generate foam in the ink on the water diversion seam of the water diversion tail when the pen absorbs ink, and the absorbed air is basically directly absorbed into the piston cavity through the air cavity area and the exhaust pipe instead of entering the ink cavity through the water diversion tail mounting hole, so that the foam generated in the ink cavity can be avoided; and the ink is mainly sucked into the ink cavity through the water tail mounting hole. Even if a small amount of foam can be generated during ink absorption, the foam can be broken in the air cavity area, the broken gas and a small amount of fine foam are sucked into the piston cavity through the exhaust pipe, and the fine foam can be further broken and dissipated through the exhaust pipe. The characteristic is that any pen does not have, such as Nippon Baile CON-70 push type ink absorber, even the pen head is completely immersed in ink to absorb ink, and the ink absorber is very expensive, and one pen can be up to 70 yuan. And secondly, the defects of ink leakage and uneven ink discharge of the existing pen can be overcome, and the handwriting after ink absorption is always uniform in thickness. The reasons are two reasons: firstly, the pen can absorb ink to ensure that the tongue of the pen cannot store excessive ink. The pen can only discharge ink in the piston cavity and cannot discharge ink in the ink cavity in a vertical state, so that the ink quantity in the pen tongue can be controlled according to the characteristic, the ink in the piston cavity can be discharged firstly after ink absorption, redundant ink in the pen tongue is sucked into the piston cavity, the suction quantity is large once, the redundant ink in the pen tongue can be sucked cleanly, and the piston rod button protective cover is screwed after ink absorption is completed, so that the ink can be prevented from being discharged accidentally by external force. Secondly, the existence of this pen air cavity district has very strong current-limiting effect to the ink output. The ink output from the ink cavity to the pen tongue and the pen point can only be carried out through the water guiding seam on the water guiding tail in the middle of the air cavity area, and the water guiding seam on the water guiding tail is very fine, so that the sectional area of the output ink on the water guiding seam is very small, the length of the output ink is at least more than 3 mm, meanwhile, the flow rate and the flow velocity of the output ink are mainly determined by the capillary action of the ink on the water guiding seam of the water guiding tail and are restrained by the hydrophobic air in the air cavity area, and the influence of external force on the output ink is very limited.

The existing pen tail is directly arranged in the ink cavity or in the lantern ring, the output ink is provided with a gap between the tail and the lantern ring besides the tail water-guiding seam, and the total sectional area of the output ink is far larger than that of CN113085408A, namely the simple pen capable of continuously absorbing ink, so that the current-limiting effect of the existing pen structure on the output ink is small, and if the ink in the tongue of the pen with the integrated rotary ink absorber is thrown downwards by force, the ink can be thrown out by a little force; ink in the tongue of other existing dark-tipped pens can be more easily thrown out. Therefore, the structural characteristics of the existing pen determine that the existing pen cannot be well realized for the two reasons, and the existing pen cannot fundamentally overcome the defects of ink leakage and uneven ink discharge.

It can be seen that the CN113085408A pen capable of absorbing ink continuously can be used for manufacturing a pen with excellent performance, and can be used as an interesting scientific experimental device.

The CN113085408A pen capable of continuously sucking ink is a brand new ink sucking technical scheme, similar patents do not exist at home and abroad including developed countries in Europe and America, the adoption of the patent is favorable for overcoming the defect that the existing pen discharges ink unevenly, replacing a push-pull ink absorber and a rotary ink absorber which are inconvenient for ink suction at present, and is favorable for promoting the upgrading and updating of the domestic pen industry and promoting the pen industry to move from low end to high end.

Therefore, how to promote the application of CN113085408A to a simple pen capable of continuously absorbing ink, which is faster and more convenient, is a problem faced by the inventor.

In addition, the CN113085408A pen capable of absorbing ink continuously has the defect that the pen holder is only suitable for being made of transparent materials to judge the ink amount in the pen holder because the ink is directly contained in the pen holder, but the pen made of the transparent materials is not attractive after absorbing ink.

Secondly, CN113085408A a simple pen capable of continuously absorbing ink has a disadvantage that it is difficult to discharge ink in the ink chamber, which causes the pen to be troublesome to clean, and only the piston device at the upper part of the pen rod can be disassembled to pour out the washing water.

Thirdly, though a simple and easy ink absorbing mode of the pen capable of continuously absorbing ink is novel, the output ink amount is small, and the pen is only suitable for writing by the pen, but is not suitable for writing brushes, water color pens, fiber pens and the like which require large ink output amount.

In addition, because the existing pens have the defects of inconvenient ink absorption, ink leakage and uneven ink discharge, and the disposable writing pens mainly using ball pens overcome the defects of the pens, the disposable writing pens have huge use amount at present, but because the disposable writing pens are disposable products, the disposable writing pens cannot be recycled, and the great resource waste and the environmental pollution are caused.

How to solve the problems is to promote the CN113085408A pen to be commercialized, manufacture products with lower cost and widen the application range, and is the problem to be solved by the invention.
