Description
Technical Field
[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a carbon powder box with an arc-shaped counting structure. Background Art
[0002] The traditional TN660 toner cartridge adopts a unique semi-arc cylindrical structure in its counting system design to achieve the counting function: the characteristic of this structure is that the counting gear rotates from low to high along the semi-arc trajectory until it reaches the set highest point and enters the positioning slot, during which it triggers the sensing element inside the printer at a specific height; however, when the toner is exhausted and the toner is refilled, it is necessary to manually remove the toner cartridge side cover to remove the counting gear from the positioning slot, and then re-engage it to the drive gear assembly. This resetting process is cumbersome and complicated, which brings inconvenience to the user.
[0003] In view of this, many manufacturers in the industry have conducted in-depth research and innovative designs on the reset problem of the toner cartridge counting gear. The mainstream solution is to add a set of external mechanisms that can reset themselves in the counting gear system. This mechanism indirectly contacts the printer sensing element by linking with the counting gear. At the same time, in order to simplify the reset operation, some designs also introduce a reset lever structure, which cooperates with the torsion spring component at the bottom of the counting gear, so that users can reset the counting gear more easily after filling the toner cartridge; however, in actual application, the above-mentioned solutions have exposed obvious limitations. Since the space reserved for the toner cartridge inside the printer is usually fixed and limited, any major changes to the structure of the toner cartridge will directly affect its overall compatibility with the printer. In order to adapt to the addition of an external mechanism that can reset itself, it is often necessary to deeply reconstruct the compact space layout of the toner cartridge. For example, it may be necessary to reduce the size of some original components or adjust their position layout, which may cause changes in the internal structure of the toner cartridge, thereby affecting its powder storage capacity, stability and other key performance indicators.
[0004] In addition, adding additional toggle structures and supporting accessories not only requires more effort to optimize integration during the design phase, but also brings additional cost pressure during the production process. On the one hand, the procurement cost of the new accessories will directly increase the material cost of the toner cartridge; on the other hand, the complex structural design and assembly process may also lead to reduced production efficiency, indirectly increasing labor and time costs, thereby significantly increasing the overall manufacturing cost of the toner cartridge.
[0005] Therefore, the utility model proposes a toner cartridge with an arc-shaped counting structure to solve the above-mentioned problem. Utility Model Content
