Description

Technical Field

[0001] The invention relates to a powder bin connection structure, in particular to a powder bin connection structure of a split toner cartridge, and belongs to the technical field of toner cartridges. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and photosensitive materials coated on the substrate. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the quality of printing is actually largely determined by the toner cartridge.

[0003] Most of the existing toner cartridges are integral. As usage needs change, there are more and more split toner cartridges. However, regardless of whether they are integral or split toner cartridges, the powder bins are mostly fixed. It is only when adding powder that the toner cartridge as a whole needs to be disassembled. Taking split toner cartridges as an example, some toner cartridges require the waste powder bin part and the powder bin part to be separated, and then the magnetic roller installed in the powder bin part must be removed before adding powder. The overall powder adding process is very cumbersome. In addition, an agitator is generally installed inside the powder bin of the split toner cartridge to increase the uniformity of the powder output. However, during the installation process of traditional toner cartridges, due to poor sealing, powder leakage will occur. At the same time, the structure of the toner cartridge is complex and assembly is more troublesome. Summary of the invention
