Description

Technical Field

[0001] The invention relates to the technical field of toner cartridges, in particular to a toner cartridge which is convenient for toner filling. Background Art

[0002] Printers are essential equipment for our daily office work, but the cost of original printing consumables toner cartridges is too high and can only be used once, which feels a bit wasteful. As a result, most users turn to domestic substitutes for easy-to-add toner cartridges, which are cheap, quality guaranteed, and most importantly, we can add toner by ourselves, which can not only greatly extend the life of the toner cartridge, but also greatly reduce costs.

[0003] The Chinese patent publication number CN220491182U discloses a toner cartridge that is convenient for filling with powder. By observing the positional relationship between the toner cartridge and the scale line, the length of the indicator rod extended at this time can be judged, so that the toner consumption in the powder box can be prompted to personnel, reminding personnel to add ink in time when the toner amount is low, avoiding the occurrence of ink interruption and ink shortage during use, resulting in printing failure and blur. The ink bottle is limited and wrapped by a feeding tube and a conical hose to avoid shaking caused by manual fixation, and it is convenient to add ink, more labor-saving, thereby preventing the toner from being shaken out of the feeding port, avoiding pollution to the surrounding environment, and avoiding waste of toner.

[0004] However, in the process of adding powder to the powder box through the feeding tube, the toner added from the feeding tube tends to accumulate below the feeding tube. This accumulation phenomenon makes it difficult for the added toner to be evenly distributed throughout the powder box. During use, users may encounter incomplete use of toner, that is, part of the toner cannot be effectively utilized due to uneven distribution. This not only affects the printing effect, but may also cause waste of resources and environmental pollution. Summary of the invention
