Toner cartridge with external reset structure

Abstract

The invention discloses a toner cartridge which is more reliable in performance and is provided with an external reset structure capable of accurately recognizing a machine without accurate alignment. The toner cartridge comprises a toner cartridge body and a stirring frame arranged in the toner cartridge body, a detection device is arranged at the side end of the toner cartridge body and comprises a stirring gear, a reset gear, a torsion spring and an end cover, the stirring gear is installed on an extension shaft of the stirring frame, and the reset gear and the torsion spring are both installed in the end cover. The reset gear is meshed with the stirring gear and comprises a connecting column and an incomplete gear which are integrally formed through injection molding, a first arc-shaped protruding block and a second arc-shaped protruding block are arranged at the upper end of the incomplete gear, a first protruding block is arranged at the top of the connecting column, and a slope protruding block matched with the first protruding block is arranged on the end cover; and a stop block matched with the torsion spring is arranged on the side wall of the lower end of the connecting column. The invention is applied to the technical field of printing supplies.

Description

technical field [0001] The invention relates to a carbon powder box, in particular to a carbon powder box with an external reset structure. Background technique [0002] Brother, Xerox, Lenovo and other series of laser printing toner cartridges in the market are all equipped with a detection device. When the toner cartridge is put on the machine, the detection device touches the sensor of the machine and sends a signal to the machine at the same time. Cartridges are identified, and a number of printed pages is defaulted. At this time, the detection device is invalid. When the user's printing volume reaches this number, the machine stops printing. When the detection device is damaged or improperly operated, the machine cannot detect the toner cartridge and cannot be used. [0003] BROTN2425 / 760, XERP235, RICSP230 and other series of product testing devices have the same structure and working reasons, and the most common testing devices in the industry are basically developed ...

AI Technical Summary

Problems solved by technology

[0004] In addition, there is also an automatic reset structure in the market. As long as the toner cartridge is taken out and reinstalled in this structure, the machine will be reset again. However, the toner cartridge may be jammed during actual use, so the machine will be reset again. With zero calculation, the printing volume of the toner cartridge cannot be accurately calculated, and at the same time, the toner cartridge cannot be reported to stop when it runs out of toner.
