[ working procedure of counting Assembly ]
FIG. 6A is a schematic view showing the state of the components in the developing cartridge before counting according to the present invention; fig. 6B is a schematic view showing a state of the components in counting in the developing cartridge according to the present invention; fig. 6C is a schematic view of the state of the components in the developing cartridge after counting according to the present invention; FIG. 7 is a schematic view showing the relative positions of the counting member and the driven member after counting in the developing cartridge according to the present invention; fig. 8 is a side view showing the relative positions of the counting member and the driven member after counting in the developing cartridge according to the present invention.
As shown in fig. 6A, before the start of counting, the pressing member 123 is kept in contact with the step surface 32D, at this time, the power receiving portion 32e of the counting member 32 is combined with the power transmitting portion 312 of the driven member 31 (as shown in fig. 3D), the spring 33 is compressed, and thus, when the driven member 31 receives the driving force of the driving member 15 to start rotating, the counting member 32 is also driven to rotate in the direction shown by r in the drawing, and at the same time, the protrusion 32b is also rotated in the direction shown by r.
Since the pressing member 123 is integrally formed with the second end cap 12, the pressing member 123 is kept stationary during the movement of the counting assembly 30, as shown in fig. 6B, the release groove 32h gradually approaches the pressing member 123 as the counting member 32 rotates in the r direction, as shown in fig. 6C, when the release groove 32h is opposite to the pressing member 123, the pressing member 123 enters the release groove 32h, the counting is completed, the counting member 32 is no longer pressed by the pressing member 123, the counting member 32 moves away from the driven member 31 by the elastic restoring force of the spring 33, as shown in fig. 7 and 8, the power receiving portion 32e is disengaged from the power transmitting portion 312, at this time, the driven member 31 remains engaged with the driving member 15 and always receives the driving force of the driving member 15 to rotate in the r direction, and the counting member 32 remains stationary as no longer receives the driving force of the driven member 31.
As can be seen from the above, as long as the counting assembly 30 has not completed counting, the pressing member 123 needs to be kept in contact with the step surface 32d, and once the counting is completed, the pressing member 123 can enter the releasing groove 32h to disengage the counting member 32 from the driven member 31, so that the contact position of the pressing member 123 and the step surface 32d can be determined according to the rotation angle of the counting member 32 before the counting starts.
When the counting assembly 30 needs to be reset, only the elastic force of the spring 33 needs to be overcome, the counting member 32 is pressed towards the direction approaching to the driven member 31, so that the pressing member 123 does not overlap with the releasing groove 32h in the direction of the rotation axis L3, meanwhile, the counting member 32 continues to rotate along the direction indicated by r, the pressing member 123 returns to the step surface 32d and keeps in contact with the step surface 32d, and the spring 33 is compressed again, so that the counting member 32 and the driven member 31 are combined again, and the counting assembly 30 can count next time.
In the embodiment of the present invention, in order to prevent the pressing member 123 from entering the release groove 32h before counting to cause the counter member 32 to disengage from the driven member 31, as shown in fig. 3A, the counter member 32 further includes a blocking portion 32i provided on the step surface 32d, preferably, the blocking portion 32i is a protrusion extending from the step surface 32d in a direction away from the power receiving portion 32e, further, in the rotation direction r of the counter member 32, the blocking portion 32i is provided upstream of the release groove 32h, and further, the blocking portion 32i is provided adjacent to the release groove 32h, so that the pressing member 123 is effectively prevented from rotating in a direction opposite to the direction r by the contact of the blocking portion 32i with the pressing member 123 before the counting of the counter assembly 30 starts, that is, before counting does not occur, the pressing member 123 enters the release groove 32h.
After the counting assembly 30 finishes counting once, an operator only needs to reset the counting piece 32 according to the operation, so that the counting assembly 30 can count the next time, and the operator is not required to disassemble the developing box to reset the counting piece 32, so that the yield of the developing box is effectively improved.
