With the improvement of ink technology, the handwriting of ball-point pens basically achieves erasable performance. However, the erasable ink has a high viscosity and poor fluidity, and the writing is not smooth. For this reason, Chinese patent 96204012.6 discloses a kind of erasable ballpoint pen, which is composed of a piston seat and a T-shaped cylindrical inner plug. The piston seat is cylindrical, and three semicircular rings are arranged on the cylindrical surface. Blind hole, one-time compression molding of elastic oil-resistant rubber. The lower end of the T-shaped cylindrical inner plug matches the blind hole in the inner cavity of the piston seat and is injection molded. The utility model changes the action point of the spring force on the piston, eliminates the deformation of the piston made of elastic material under the spring pressure, improves the sliding performance of the piston along the inner wall of the pen holder or the pen core, and makes the product pass rate high. Long storage period in commercial circulation. However, the internal space of the pen core is limited, and the compression capacity of the spring cannot be set larger, which cannot fundamentally solve the above problems. Therefore, need to provide a kind of novel environment-friendly erasable grease pen to be used for overcoming above-mentioned technical defect.

2、本实用新型的笔迹既可以使用普通的橡皮擦除，还可以长期保存，兼有铅笔和钢笔的优点，又可以节约大量木材，起到环保作用。2. The handwriting of the utility model can be erased with a common eraser, and can also be stored for a long time. It has the advantages of pencils and pens, can save a lot of wood, and has an environmental protection effect.
附图说明Description of drawings
以下结合附图及实施例对本实用新型作进一步说明。Below in conjunction with accompanying drawing and embodiment the utility model is described further.
图1为本实用新型的结构示意图。Fig. 1 is the structural representation of the utility model.
具体实施方式 Detailed ways
参见图1所示，本实用新型的环保可擦油笔，有一个空心的塑料笔杆5，其内装有一个金属笔芯7，所述笔芯上部设有一个压缩气囊4，下部设有一个油墨腔室6，所述压缩气囊底部设置一个密封滑套9，所述压缩气囊内充有压缩气体，所述油墨腔室内充有可擦油墨。所述金属笔芯底部安装书写笔尖8，所述金属笔芯顶部设有一个端盖3，该端盖上设置一个充气针孔。在本实施例中，所述压缩气囊采用优质的弹性强的橡胶材料，压缩气囊内充有惰性压缩气体(通常是氮气或者氦气)，所述压缩气体的压力为0.2-0.4Kpa(相当于2-4个大气压)。所述可擦油墨可以采用现有技术的油墨产品。所述的笔杆顶部装有笔帽2，其上装有橡皮擦1。笔帽与笔杆可以采用螺纹连接方式固定，也可以采用粘接固定。Referring to Fig. 1, the environmental protection oil-erasable pen of the present utility model has a hollow plastic pen holder 5, and a metal pen core 7 is housed in it, and a compressed air bag 4 is provided at the top of the pen core, and an ink pen is provided at the bottom Chamber 6, a sealing sliding sleeve 9 is arranged at the bottom of the compressed air bag, the compressed air bag is filled with compressed gas, and the ink chamber is filled with erasable ink. A writing nib 8 is installed at the bottom of the metal pen core, and an end cap 3 is arranged on the top of the metal pen core, and an air-filled pinhole is arranged on the end cap. In this embodiment, the compressed airbag is made of high-quality elastic rubber material, and the compressed airbag is filled with an inert compressed gas (usually nitrogen or helium), and the pressure of the compressed gas is 0.2-0.4Kpa (equivalent to 2-4 atmospheres). The erasable ink can adopt the ink products of the prior art. A pen cap 2 is provided on the top of the penholder, on which an eraser 1 is housed. The pen cap and the pen holder can be fixed by means of threaded connection, or can be fixed by bonding.
在本实施例中，所述为了保证油墨腔内的油墨不向上溢出，所述的密封滑套与金属笔芯的内壁面采用滑动密封结构，该结构属于现有技术，不详细描述。本实施例的安装顺序是，先将可擦油墨注入金属笔芯下部的油墨腔室，然后装入密封滑套，再装入压缩气囊，压固端盖(使端盖与金属笔芯牢固连接成一体)，再利用压缩气体设备通过充气针孔向压缩气囊中充入压缩气体，压缩气囊中有事先设置的自补胶粘剂，当充气完成拔出充气针后，压缩气囊上的针孔自动消失。采用压缩气囊方式可以长期保持笔芯内压力稳定。In this embodiment, in order to ensure that the ink in the ink chamber does not overflow upwards, the inner wall of the sealing sleeve and the metal pen core adopts a sliding sealing structure. This structure belongs to the prior art and will not be described in detail. The installation sequence of the present embodiment is that the erasable ink is first injected into the ink chamber at the bottom of the metal pen core, then the sealing sliding sleeve is packed into, and then the compressed air bag is packed into, and the end cap is pressed firmly (the end cap is firmly connected with the metal pen core) Integrate), and then use the compressed gas equipment to fill the compressed air bag with compressed gas through the inflation pinhole. There is a pre-set self-replenishing adhesive in the compressed air bag. When the inflation is completed and the inflation needle is pulled out, the pinhole on the compressed air bag disappears automatically. . The pressure in the refill can be kept stable for a long time by adopting the method of compressing the air bag.
本实用新型的环保可擦油笔，在实际使用过程中，随着可擦油墨的消耗减少，压缩气囊逐渐膨胀，维持油墨腔室的正压力，保证笔尖处的油墨供应充足，必要时还可以向压缩气囊内补充压缩气体。The environment-friendly erasable oil pen of the utility model, in the actual use process, as the consumption of the erasable ink decreases, the compressed air bag gradually expands to maintain the positive pressure of the ink chamber and ensure sufficient ink supply at the pen tip. Add compressed gas to the compressed air bag.
