Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a toner cartridge, an image forming device, and a printer. Background Technology

[0002] The existing toner cartridge is a very important component in laser printers. It contains toner for printing. Toner is a mixture of tiny plastic particles and ink. Laser printers use a laser beam to transfer images or text onto paper. The toner adheres to the paper by electrostatic force and is then fixed to the paper by a heating process to form the final printed output. Simply put, the toner cartridge provides the ink needed for printing and helps to transfer it onto the paper.

[0003] However, existing toner cartridges lack automatic cleaning functions, and residual toner may cause unstable print quality or streaks and blurriness. They also increase maintenance workload, requiring users to manually clean the toner cartridges and the inside of the printer, which increases maintenance workload and time. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a toner cartridge, an image forming device, and a printer. A lead screw can drive a carrier plate to move forward. After the carrier plate moves, the brush bristles at the front can brush off the residual toner inside the toner cartridge. An air pump draws air from inside the waste toner box, thereby generating suction in the suction pipe to remove the brushed waste toner, thus achieving automatic cleaning. This can effectively reduce toner residue and clogging, maintain stable print quality, reduce the need for manual cleaning, reduce the user's cleaning workload, and keep the inside of the toner cartridge clean, thereby improving toner utilization and improving overall printing efficiency.

[0005] This utility model also provides a toner cartridge, an image forming device, and a printer as described above, comprising: a toner cartridge body, wherein the toner cartridge body is provided with two sliding grooves, and a lead screw is rotatably connected to the inner surface of each of the two sliding grooves.
