Description

Technical Field

[0001] The utility model relates to the technical field of ink supply devices, in particular to an ink replenishing device. Background Art

[0002] With the development of printer technology, ink tank printers have emerged. The print head and ink supply system are set separately, which makes the printer print more. Since ink tank printers do not use traditional ink cartridges, users only need to refill ink according to prompts, which improves the cost and environmental protection of ink tank printers, and is favored by more and more users.

[0003] In the prior art, the ink supply system of a printer generally includes a bottle body and a bottle cap. The bottle body can hold ink, the opening of the bottle body is sealed by welding a sealing film, and the bottle body and the bottle cap are connected and fixed by threads. In the process of refilling ink, the user needs to remove the bottle cap, pierce the sealing film with a sharp object, then install the bottle cap, and then refill the ink into the printer. If the operation is improper during the process of piercing the sealing film and tightening the bottle cap, it is easy to cause ink leakage, causing pollution, which greatly affects the convenience of using the printer. Summary of the invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide an ink refilling device, which improves the sealing and safety of the bottle body and ensures the stability and convenience of use of the ink refilling device.
