技术领域technical field
本实用新型涉及一种碳素记号笔，更具体地说，本实用新型涉及一种可重复使用的碳素记号笔，属于文具技术领域。The utility model relates to a carbon marking pen, more specifically, the utility model relates to a reusable carbon marking pen, which belongs to the technical field of stationery.
背景技术Background technique
碳素记号笔是记号笔的一种，可永久附著，不脱色，有标准的12色，可在任何纸上、塑胶、玻璃、白板、金属等大部分固体上书写，碳素墨水属油性，无毒，可以用酒精等有机溶剂擦去笔迹，与教学中的白板笔类似，可替代白板笔在纸张、玻璃和白板上使用，过后用酒精擦拭或永久附着。如果因笔盖没有盖严，油墨干燥而无法正常书写，可将笔头拔掉后加入一些酒精，将油墨稀释后，便可写出。Carbon marker pen is a kind of marker pen, which can be permanently attached and does not fade. There are 12 standard colors. It can be written on any paper, plastic, glass, whiteboard, metal and most other solids. Carbon ink is oily. It is non-toxic and can be wiped off with organic solvents such as alcohol. Similar to whiteboard markers in teaching, it can be used instead of whiteboard markers on paper, glass and whiteboards, and then wiped with alcohol or permanently attached. If the pen cap is not tightly closed and the ink is dry and cannot be written normally, you can unplug the pen tip and add some alcohol to dilute the ink before writing.
碳素记号笔在使用时身边常常没有现成的酒精可用，而笔盖打开后往往忘记关掉。油墨干燥后，常会被误认为记号笔已经无法再使用而丢弃，造成碳素记号笔的浪费。When using carbon marker pens, there is often no ready-made alcohol available, and the pen cap is often forgotten to be turned off after opening. After the ink dries, it is often mistakenly considered that the marker pen is no longer usable and discarded, resulting in waste of carbon marker pens.
国家知识产权局于2012年08月01日公开了申请号为CN201120495867.0，名称为耐用记号笔的实用新型专利：它是在笔杆的前端设有笔头，笔杆的中心部设有笔芯，笔芯内设有可吸墨的软质绵，笔杆的后端设有外螺纹，外螺纹上装有吸墨注射管，吸管内设有吸墨活塞，吸墨活塞的后端设有推拉手柄，吸墨注射管的前端设有向笔芯注射墨水的注射连接管，吸墨注射管的前管内设有内螺纹，使用时将墨注射管内吸满所需用的墨水，把吸墨注射管的内螺纹紧固在笔杆后端的外螺纹上，使吸墨注射连接管插入笔芯后端的管口内，向左推动手柄，即可将吸墨注射管内的墨水注入笔芯中。On August 1, 2012, the State Intellectual Property Office published a utility model patent with the application number CN201120495867.0 named durable marker pen: it has a nib at the front end of the pen holder, and a refill at the center of the pen holder. The core is provided with soft cotton that can absorb ink, and the rear end of the pen holder is provided with external thread, and the external thread is equipped with an ink-absorbing injection tube. The front end of the ink injection tube is provided with an injection connection tube for injecting ink into the pen core, and the front tube of the ink suction injection tube is provided with an internal thread. The thread is fastened on the external thread at the rear end of the pen holder, so that the ink-absorbing injection connecting tube is inserted into the nozzle at the rear end of the pen core, and the handle is pushed to the left to inject the ink in the ink-absorbing injection tube into the pen core.
上述现有技术中，墨水注入时不能准确定位，可能会注入到笔杆内部的中空位置，而不能对笔芯进行精确加墨，同时墨水注入位置的不准确会导致墨水渗出而容易脏手。同时，吸墨注射管内部的墨水用完后无法再进行补充。In the above-mentioned prior art, the ink cannot be accurately positioned when it is injected, and it may be injected into the hollow inside the pen holder, so that the pen core cannot be filled with ink accurately. At the same time, the inaccurate ink injection position will cause the ink to ooze out and easily dirty hands. At the same time, the ink inside the ink suction syringe cannot be replenished after it is used up.

本实用新型带来的有益技术效果：Beneficial technical effects brought by the utility model:
1、本实用新型酒精筒内注入一定量的酒精，通过负压活塞将酒精推入到笔身内部的笔芯中，酒精筒采用透明材质，能够观察负压活塞的推进量和酒精筒内部的酒精含量。设置的把手一方面可以为推动负压活塞运动提供着力点，另一方面把手的尾部为橡胶塞，在酒精筒内部的酒精使用完后，可以通过针管透过橡胶塞向酒精筒内部补充酒精，从而达到了重复使用的目的。1. A certain amount of alcohol is injected into the alcohol cylinder of the utility model, and the alcohol is pushed into the pen core inside the pen body through the negative pressure piston. alcohol content. On the one hand, the set handle can provide a force point for pushing the negative pressure piston to move. On the other hand, the tail of the handle is a rubber plug. After the alcohol inside the alcohol cylinder is used up, alcohol can be replenished into the alcohol cylinder through the rubber plug through the needle tube. Thereby achieving the purpose of repeated use.
2、优选的，本实用新型筒嘴位于酒精筒一端底部的边缘。在推动负压活塞的时候，将本实用新型横放，在重力的作用下，笔芯也在笔身的凹槽内，保证了筒嘴和笔芯之间的直接准确接触，提高了酒精注入的准确性。2. Preferably, the nozzle of the utility model is located at the edge of the bottom of one end of the alcohol cylinder. When pushing the negative pressure piston, put the utility model horizontally, under the action of gravity, the refill is also in the groove of the pen body, which ensures the direct and accurate contact between the nozzle and the refill, and improves the alcohol injection accuracy.
3、优选的，本实用新型筒嘴沿笔头方向逐渐变小。让酒精筒内部的酒精能够在负压活塞的压力下缓慢的进入到笔身，从而缓慢的浸润笔身内部的笔芯。避免一次性酒精的注入量过多，造成笔身内部的酒精过多溢出的情况出现。同时可以使得筒嘴精确定位到笔芯，防止酒精注入到其他位置。3. Preferably, the nozzle of the utility model gradually becomes smaller along the direction of the nib. The alcohol in the alcohol cylinder can slowly enter the pen body under the pressure of the negative pressure piston, thereby slowly infiltrating the pen core inside the pen body. Avoid excessive injection of one-time alcohol, which may cause excessive alcohol overflow inside the pen body. At the same time, the nozzle can be accurately positioned to the refill, preventing alcohol from being injected into other positions.
4、优选的，本实用新型酒精筒底部设置有固定膜。固定膜将负压活塞与酒精筒之间进行密封从而防止漏气和漏出丙酮酒精，既能保证负压活塞能在酒精筒内部运动，又能给负压活塞运动提供摩檫力，防止负压活塞的推动程度过大而导致酒精筒内的酒精推出过多。4. Preferably, the bottom of the alcohol cylinder of the present utility model is provided with a fixed film. The fixed film seals the negative pressure piston and the alcohol cylinder to prevent air leakage and acetone alcohol leakage. It can not only ensure that the negative pressure piston can move inside the alcohol cylinder, but also provide friction for the movement of the negative pressure piston to prevent negative pressure. The piston is pushed too far and the alcohol in the alcohol cylinder is pushed out too much.
5、优选的，本实用新型酒精筒的两端设置有内螺纹，笔身和笔尾盖设置有外螺纹。通过内螺纹，酒精筒分别与笔身和笔尾盖的外螺纹连接，连接方便简便。同时，通过调节筒嘴所在端内螺纹和外螺纹的匹配程度，可以调节筒嘴深入笔芯的长度，从而调节酒精的注入位置和范围。5. Preferably, both ends of the alcohol cylinder of the present invention are provided with internal threads, and the pen body and the tail cap are provided with external threads. Through the internal thread, the alcohol cylinder is respectively connected with the external thread of the pen body and the pen end cap, and the connection is convenient and simple. At the same time, by adjusting the matching degree of the inner thread and the outer thread at the end of the barrel nozzle, the length of the barrel mouth into the pen core can be adjusted, thereby adjusting the injection position and range of alcohol.
6、优选的，本实用新型负压活塞的厚度为酒精筒的六分之一。负压活塞太厚将占据酒精筒的空间，减少酒精注入量；薄于六分之一可导致负压作用减弱，注入的酒精从活塞底部溢出而浪费。6. Preferably, the thickness of the negative pressure piston of the present utility model is one-sixth of that of the alcohol cylinder. If the negative pressure piston is too thick, it will occupy the space of the alcohol cylinder and reduce the amount of alcohol injection; if it is thinner than one-sixth, the negative pressure effect will be weakened, and the injected alcohol will overflow from the bottom of the piston and be wasted.
7、优选的，本实用新型酒精筒内壁上设置有多个等距的突起边缘，这个突起边缘能够给负压活塞运动带来一定的摩檫力，防止负压活塞运动过快而使得酒精注入过多溢出，油墨从而弄脏手。突起边缘和固定膜一起配合，才能更好的到达节能、多次使用的目的。7. Preferably, the inner wall of the alcohol cylinder of the utility model is provided with a plurality of equidistant protruding edges, which can bring a certain amount of friction to the movement of the negative pressure piston, preventing the negative pressure piston from moving too fast and causing the alcohol to be injected Spill too much and the ink will stain your hands. Only when the protruding edge cooperates with the fixed film can the purpose of energy saving and repeated use be better achieved.
