In some variations, the number of the protrusions may be set by simply changing the design according to the specific application, so that the design flexibility of the detection mechanism is high.
In this embodiment, specifically, when the developing cartridge 10 is installed in the printer, the printer transmits a driving force to the driving force receiving portion 11, so as to drive the driving force receiving portion 11 to rotate, and further the driving connecting portion 122 of the driving portion 12 drives the detecting portion 13 to swing; when the detection portion 13 moves from the initial position to the end position, the printer can complete the detection of the developing cartridge 10.
With respect to the first-installed developing cartridge 10, referring to fig. 1, in the initial state, the power portion 131 is in a connection state with one of the driving connection portions 122, and at this time, the second detecting portion 133 of the detecting portion 13 is rotationally triggered to the trigger switch of the printer by the driving action of the driving connection portion 122, and the printer outputs an electric signal, that is, the initial position; then, the detecting portion 13 continues to rotate to the intermediate state, as shown in fig. 4, the power portion 132 is connected to another driving connecting portion 122 after being separated from the driving connecting portion 122, at this time, the first detecting portion 132 of the detecting portion 13 rotates and triggers a trigger switch of the printer under the driving action of the another driving connecting portion 122, and the printer outputs an electrical signal, that is, the end position; then, the detection portion 13 continues to rotate to the end state, as shown in fig. 5, the power portion 132 is finally disengaged from the other drive connection portion 122, and thereafter the power portion 132 disposed in the U-shape is no longer connected to any one of the drive connection portions 122.

Specifically, for example, the powder bin housing 14 is correspondingly provided with a limit groove 141, when a detection part of the detection part 13 triggers a trigger switch of the printer, the positioning part 134 is clamped in the limit groove 141, so that the detection part of the detection part 13 is limited, the swing of the detection part 13 can be further limited, and the situation that the positioning is unstable and shakes to influence the detection function of the detection part 13 is prevented; and when the detecting part does not trigger the trigger switch of the printer at the middle position, the positioning part 134 is disengaged from the limiting groove 141.
In some modifications, the number of the detecting portions of the detecting portion 13 is not limited to two, and the number of the detecting portions may be one, three or more, and meanwhile, the driving connecting portion 122 corresponding to the driving portion 12 may be plural, and the trigger switch of the printer is triggered in different forms or different combinations, for example, the detecting portion 13 at the intermediate state at least includes a cycle of first disengaging, triggering again, and disengaging from the trigger switch of the printer, so that the printer outputs different kinds of detection signals, and thus the developing cartridge 10 may be compatible with printers of various models, and the practicability and compatibility of the developing cartridge are enhanced.
In the present embodiment, as shown in fig. 1 to 5, the driving portion 12 and the detecting portion 13 are located on the same side of the developing cartridge 10, and the mounting process is simple.
