[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, of guaranteed quality, 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] Publication No. CN218825157U discloses a dust cover for adding powder to a printer cartridge. The device pours the powder needed to add to the printer cartridge into the powder injection tube by twisting the knob cover. A dust cover is provided on the periphery of the powder adding box. The spilled powder is collected in the dust cover, which is convenient for cleaning the dust. At the same time, an external threaded connection barrel is provided at the lower end of the dust cover. The external threaded connection barrel is threadedly assembled with the internal threaded connection barrel on the cartridge to reduce the spillage of the added powder from the connection port, thereby reducing the leakage of powder in the printer cartridge during the powder adding process, and reducing the impact on health and machine failure rate after human inhalation.

When 302 follows the mounting base 101 to be pulled out, the first squeezing rod 310 can be driven upward by the contractility of the second telescopic spring 311, thereby assisting the plug block 302 to be pulled out, which brings convenience to the staff when using it, and the outlet of the powder box is stuck in the funnel box 102. At this time, the limit plate 103 is squeezed, and then the second squeezing rod 104 is driven to squeeze the third telescopic spring 106, thereby achieving the effect of adaptive fixation of the powder box, and can be clamped and fixed according to powder boxes of different specifications, which is convenient for subsequent staff to add powder to the toner cartridge.
