Abstract

The invention discloses a circulating ink-injecting neutral pen, belonging to the neutral pen field. The pen comprises a pen body, a pen head connected with the lower part of the pen body, a pen tip is installed on the pen head, an ink storage chamber is arranged inside the pen body, and the ink storage chamber communicates with the pen tip. A membrane is arranged on the inner wall of the ink storage chamber. The ink storage chamber is provided with a piston, an ink injection nozzle for communicating with the outer wall of the pen body is arranged on the inner wall of the ink storage chamber below the piston, an air bag is arranged in the ink storage chamber above the piston, the air bag is connected with an air valve, a through hole communicating with the ink storage chamber is arranged on the outer wall of the pen body, and the air valve is fixedly installed in the through hole. The invention is reasonable in design and simple in structure, and can not only make the neutral pen circularly used for ink injection, but also prevent ink sputtering when the pen body is fragmented, and prevent ink from sticking and unsmooth descending.

Description

technical field [0001] The invention relates to the field of gel pens, in particular to a gel pen for circulating ink. Background technique [0002] As a writing tool, the gel pen has become a mainstream writing tool because of its smooth writing and ease of use, and hundreds of millions of gel pens are used every year. [0003] At present, gel pens all have refills, and the refills are used to store ink. After the ink of the gel pen is used up, the refill needs to be replaced to continue to use; It is made of plastic, and it is difficult to collect the used refills in a centralized manner, so they can only be discarded as plastic waste. This not only pollutes the environment, but also costs the purchase and manufacture of refills for users and manufacturers. expenditure. Contents of the invention [0004] Aiming at the problem in the prior art that gel pens need to be constantly replaced with refills, the purpose of the present invention is to provide a cycle-filling ge...
