Problems solved by technology

The existing toner cartridge generally adds developer to the inside of the cylinder through the piston installation port on the cylinder, but this method of adding developer requires the removal of the entire piston, which is complicated to operate and is not conducive to the operation of the operator.
If the powder filling port is directly opened on the cylinder body, in orde...

Abstract

The invention relates to a powder adding component of a carbon powder barrel. The carbon powder barrel comprises a barrel body, the power adding component is matched with the barrel body and can be axially and movably arranged in the barrel body in the axial direction of the barrel body; the power adding component comprises a hollow piston rod provided with a developer inlet and a developer outlet; and a sealing cover is arranged at the developer outlet, and the developer outlet can communicate with or is disconnected from the inner cavity of the cylinder body. According to the invention, thehollow piston rod is ingeniously utilized to form the powder adding channel, and the powder adding channel is opened or closed by matching with the sealing cover, so that the operation of an operatoris facilitated; and moreover, a powder feeding port is directly formed at the side wall of the barrel body, and the size of a filling channel is increased, so that the filling efficiency is improved,and the phenomenon that the developing powder is seriously leaked in the moving process of the piston can be avoided.

Description

technical field [0001] The invention relates to a toner cartridge for adding toner to image forming equipment, and a toner filling assembly used in the toner cartridge. Background technique [0002] Image forming equipment such as laser printers and copiers usually has an image processing unit and a developing unit. The developer such as toner provided by the developing unit is used to develop the electrostatic latent image formed on the image processing unit to form a visible image on paper and other media. Among them, toner (developer) is a consumable item that needs to be continuously replenished to the developing unit in the image forming apparatus. In the past, the toner cartridge of the developing unit was directly filled with developer toner through holes; but now there are image forming devices that need to use an external toner cartridge to add developer to the developing unit in the image forming device. The existing toner cartridges generally add developer to the...
