Description

Technical Field

[0001] The present invention relates to the technical field of ink cartridges, and in particular to an anti-overflow safety ink cartridge. Background Art

[0002] Ink cartridges mainly refer to the components used to store printing ink and finally complete printing in inkjet printers. After searching, the patent document with the authorization announcement number CN2767168Y discloses a new type of printer ink cartridge, including a box body, a cover, a reflective device and a photosensitive device, characterized in that the reflective device is a reflective mirror. The reflective device is arranged at the bottom of the box body, and a channel for ink to pass through is arranged between the reflective device and the bottom plate of the box body. The bottom plate of the box body is inclined, and its ink outlet is located at the lowest point of the bottom plate of the ink cartridge, and the reflective device is higher than the ink outlet. Compared with the existing printer ink cartridges, it has the advantages of simple structure, low cost and easy manufacturing. It can also reduce the amount of residual ink in the ink cartridge after use. It is widely applicable to various types of printers and is an ideal substitute for existing printer ink cartridges.

[0003] However, printer ink cartridges can store ink. When filling ink, the box cover needs to be opened, and then the ink is injected into the ink cartridge through a syringe. Since the ink cartridge is a black plastic structure, the liquid level cannot be seen clearly during ink filling, which can easily cause ink overflow. In addition, the rubber plug is installed loosely and is easy to loosen and slip off. When the ink cartridge is shaken, ink overflow is also likely to occur. Therefore, we propose an anti-overflow safety ink cartridge to solve the above problems. Summary of the invention
