Novel carbon powder box detecting device and carbon powder box

Abstract

The invention discloses and provides a novel toner cartridge detection device and a toner cartridge which have low precision requirements and are beneficial to reduce defective products produced. The toner cartridge includes a toner cartridge body, a stirring frame arranged in the toner cartridge body, a developing roller, a powder feeding roller, and a toner cartridge detection device, and the toner cartridge detection device includes a toner cartridge body, a terminal Cover, spring, torsion spring and reset gear, the spring is arranged between the reset gear and the toner cartridge body, and the end face of the reset gear facing the end cover is provided with an arc-shaped bump and a limiter. position bump, the top of the arc-shaped bump passes through the outer side of the end cap, the limit bump is in contact with the inner side of the end cap, and the torsion spring is fixed on the outer side of the end cap On the side, one of the legs is in contact with the end cap, and the other leg is in contact with the side of the arc-shaped protrusion. The invention can be widely used in the field of laser printing toner cartridges.

Description

technical field [0001] The invention relates to a novel toner box detection device and the toner box. Background technique [0002] Generally, during the use of laser printers, it is necessary to calculate the number of printed pages of the consumables, because the user can replace the new drum assembly or toner cartridge in time only after knowing the remaining life of the consumables, so as to avoid affecting the normal use of users. [0003] Toner cartridge detection on BROTN660 / 630 / 2325 / 2312 / 2375 / 2335, BROTN750 / 720 / 780 / 3330 / 3320 / 3335 / 3310 / 3380 / 3350 / 3325 / 3340 / 3360 / 3390 / 3370 / 3395 series products The structure and working principle of the device are basically the same. The printer drives the gear to rotate, and the gear of the transmission mechanism on the powder box drives the reset gear to rotate in a circular arc. The limit block of the detection device corresponds to a low-high-low slope on the powder bin body. , the reset gear rotation track process starts from the lo...

Problems solved by technology

[0004] This kind of reset gear transmission structure is to ensure that the installed machine can recognize and count normally. The rotation track of the reset gear is set to move from low to high, and then from high to low. This requires high manufacturing and installation accuracy. If the requirements are not met, the problem of the toner cartridge not being detected by the machine is likely to occur, resulting in problems such as high defect rate and high cost pressure.
