Problems solved by technology

[0003] Most of the common white class on the market is designed as a refillable ink solution, allowing the user to open the end of the pen tube to inject the ink solution into the ink-absorbing strip in the tube when the ink is used up, and then use it without throwing it away as a whole. In response to the concept of environmental protection, but since the process of filling new ink must be carried out with the pen tube open, it must first be erected with the help of auxiliary tools to prevent it from falling over, and then the user unscrews the container containing the replenishing liquid to replace it. The mouth of the bottle must be aligned with the tube and injected carefully, and the flow rate must be controlled so that it is not too much or not enough. If the operation is not careful, the filling liquid will easily overflow, which will not only cause waste, but also pollute the desktop environment and the user's hands or clothes, making it difficult to clean. trouble
