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.

In this embodiment, the developing cartridge 10 is installed in the printer, if the developing cartridge 10 is installed and used for the first time, the printer driving head transmits a driving force to the driving force receiving portion 11 to drive the driving force receiving portion 11 to rotate, the driving force receiving portion 11 further drives the driving portion 12 to rotate, the detecting portion 13 is driven again to successively trigger the trigger switch of the printer at least twice, the printer outputs different series of electrical signals, and after the trigger switch of the printer is triggered for the last time, the detecting portion 13 is separated from the driving portion 12 and cannot be driven by the driving portion 12 again; if the cartridge 10 is not mounted and used for the first time, the detection unit 13 is in a state of being detached from the driving unit 12 and cannot be driven by the driving unit 12 when the cartridge 10 is mounted in the printer; on the other hand, for the developing cartridge 10 after refilling, the detecting portion 13 may be reset by an external force in a direction opposite to the driving force of the driving portion 12, which is the simplest way, by manual pushing, and the detecting portion 13 may be reset by a pushing force in a direction opposite to the driving force, so that the developing cartridge 10 may be recycled, and resources may be saved.
In summary, in the installation process of the developing cartridge 10, whether the currently installed developing cartridge 10 is used for the first time or not is determined by whether the detection part 13 triggers the trigger switch of the printer, so that the output signals of the printer are different; further, it is also possible to detect the first-mounted developing cartridge 10 of different capacity by the difference in the number of times the trigger switch of the printer is triggered by the detecting portion 13, for example, by providing more than two drive connecting portions 122 in drive connection with the power portion 132 provided in a U-shape.
In the present embodiment, the detecting part 13 is preferably further provided with a positioning part 134, and the positioning part 134 is used for positioning the detecting part 13 when a trigger switch of the printer is triggered, so as to prevent the detecting part 13 from generating unnecessary swinging.
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 this embodiment, it is preferable that the power part 131, the first and second detecting parts 132 and 133, and the positioning part 134 are integrally formed.
In some variations, 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; on the other hand, the detection of the first mounted developing cartridge 10 of different capacity may be realized by the difference in the number of times the detection section 13 triggers the trigger switch of the printer; on the other hand, it is preferable that the different capacities of the first-mounted developing cartridges 10 are also detected by adjusting the transmission ratio of the driving gear set and the structural design shape, size, pitch, etc. of the detecting portion 13 so as to realize the difference of the length rule of the single trigger time of the trigger of the detecting portion 13 to the trigger switch of the printer.
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.
In some modifications, the driving portion 12 and the detecting portion 13 may be disposed on the opposite side of the driving force receiving portion 11 in the longitudinal direction of the developing cartridge 10 (the driving portion 12 and the detecting portion 13 are on the left side in the longitudinal direction of the developing cartridge 10, and the driving force receiving portion 11 is on the right side in the longitudinal direction of the developing cartridge 10) as needed, the stirring gear may be driven as an intermediate gear, the stirring gear driving portion 12 and the detecting portion 13 may be mounted on the other end of the stirring frame, or the driving portion 12 may be directly mounted on the other end of the stirring frame to drive the detecting portion 13.
In some modifications, the driving force of the driving force receiving portion 11 may also be directly from the driving force transmitted by the developing roller or the powder feeding roller.
While the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
