Background
The space pen is a special pen designed for astronauts, and the core technology is that the space pen can be used in a gravity-free state. The common pen and ball pen finish the ink discharge of the pen point by the gravity of liquid drops, so that the pen and ball pen cannot be used in a gravity-free state; although the pencil is not limited by the gravity-free environment condition, after the pencil core is broken, the pencil core floats in the gravity-free space and possibly floats into the nasal cavity and eyes, or because the pencil core and the wood of the pencil are easy to burn quickly in a pure oxygen environment due to the fact that the pencil core has conductivity, the risk is extremely high, and therefore the pencil is quite dangerous to use in a space capsule environment. To solve this problem, space ball pens have been developed in the united states for astronauts to use in space environments, but at very high prices. At present, china also proposes space pens with different principles such as space gel pens, space ball pens, multifunctional space pens and the like. The space pen with excellent performance can be suitable for spaceflight, and can be used in severe environments such as mountain climbing, diving, exploration travel, extremely investigation exploration and the like. For example, chinese patent CN111319376a discloses a space pen cartridge that outputs ink in a balanced manner using a capillary-hole material pen cartridge. However, the space is not pressurized because of the absence of the atmosphere except for the gravity-free environment, and if the space pen core in the above patent is used when the space pen core is taken out of the capsule, the internal air pressure of the pen core is far greater than the external air pressure, so that the internal ink is extruded, and writing is affected.
