As shown in fig. 4A, since the first acting member 71 and the second acting member 72 share the third rotation axis L3, the first acting member 71 has a tendency to rotate in the direction shown by r3 'about the third rotation axis L3 and the second acting member 72 has a tendency to rotate in the direction shown by r3 about the third rotation axis L3 under the urging action of the second returning member 73, and the direction r3 is opposite to the direction r 3'.
The first operating member 71 includes a first rotating portion 713, and a first force receiving portion 711 and a first operating portion 712 connected to the first rotating portion 713, and the first operating portion 712 cooperates with the second operating member 72 to hold the counter gear 61 at a predetermined position. As shown, the first acting portion 712 includes a first extension 7121 connected to the first rotating portion 713, the first extension 7121 having a first contact portion 7123 in contact with the cylindrical circumferential surface 615a and a first support face 7122 in contact with the cylindrical distal face 615 b.

As shown, the second acting portion 722 includes a second extension 7221 connected to the second rotating portion 723, the second extension 7221 having a second contact portion 7223 in contact with the cylindrical circumferential surface 615a and a second support surface 7222 in contact with the cylindrical distal surface 615 b.
The first contact portion 7123 is opposed to the second contact portion 7223, and when the count gear 61 is located at the first position and the second position, the first contact portion 7123 and the second contact portion 7223 are simultaneously in contact with the circumferential surface 615a of the cylinder, and the count gear 61 is held at the first position and the second position by pinching the cylinder 615; when the counter gear 61 is in the third position, the first 7122 and the second 7222 simultaneously contact the cylindrical end face 615b, and the counter gear 61 is held in the third position by the first 7122 and the second 7222 together, it being understood that only one of the first 7122 and the second 7222 may be retained as long as the counter gear 61 can be held in the third position, that is, the control assembly 7 includes at least one of the first 7122 and the second 7222, and the first 7122 and the second 7222 may be collectively referred to as a support face.
Further, the control assembly 7 further includes a guide protrusion 74 for engaging with the counting track 614, and specifically, the guide protrusion 74 does not need to be limited to a specific position as long as the guide protrusion 74 can contact with the counting track 614, and the guide protrusion 74 is in abutment with the translation section 614a, the depression section 614b and the holding section 614d of the counting track 614 in sequence as the counting gear 61 rotates.
The operation of the counting device 6 and the control unit 7 will be described with reference to fig. 5A, 5B and 5C.
Fig. 5A is a schematic view of a counting device in a developing cartridge according to the present invention in an initial state; fig. 5B is a schematic view of the developing cartridge according to the present invention in which the counting means is in the intermediate state; fig. 5C is a schematic view of the counting means in the developing cartridge according to the present invention in the end state.
As shown in fig. 5A, in the initial state, the guide protrusion 74 abuts against the translation segment 614A, the first acting element 71 has a tendency to rotate in the direction shown by r 3' in fig. 4A, the second acting element 72 has a tendency to rotate in the direction shown by r3 in fig. 4A under the action of the second reset element 73, and the first contact portion 7123 and the second contact portion 7223 simultaneously abut against the cylindrical circumferential surface 615A, the tendency of the first acting element 71 and the second acting element 72 to rotate is stopped by the cylinder 615, at which time, the cylinder 615 is clamped by the first acting element 71 and the second acting element 72, so that the counter gear 61 is held at the first position where the toggle protrusion 613 is coupled with the toggle lever, preferably, the first contact portion 7123 and the second contact portion 7223 are both configured to have a shape matching the outer shape of the cylindrical circumferential surface 615A, ensuring stable clamping of the cylinder 615, and, at the same time, when the counter gear 61 rotates, the friction between the cylindrical circumferential surface 615a and the first and second contact portions 7123 and 7223 can be reduced.
When the driving force receiving member 5 starts to rotate, the intermediate gear 8 transmits the driving force to the full-tooth gear 612, the counter gear 61 rotates in the direction indicated by r2 around the rotation axis L2, the guide protrusion 74 remains stationary during the rotation of the counter gear 61, as shown in fig. 5B, when the counter gear 61 moves until the guide protrusion 74 reaches the depressed section 614B, the whole counter gear 61 moves in the direction approaching the control unit 7 (housing 1) along the rotation axis L2, the full-tooth gear 612 continues to be engaged with the intermediate gear 8, but the toggle protrusion 613 is disengaged from the toggle lever, at which time, the counter gear 61 is located at the second position, and the cylinder 615 continues to be gripped by the first acting member 71 and the second acting member 72.
As the counter gear 61 continues to rotate, the toggle projection 613 starts to abut against the ascending segment 614C, and under the guiding action of the ascending segment 614C, the counter gear 61 moves along the rotation axis L2 in the direction away from the control assembly 7 (the housing 1), the first reset element 63 elastically deforms, the toggle projection 613 gradually extends out and engages with the toggle lever again, until the guide projection 74 reaches the holding segment 614d, as shown in fig. 5C, the guide projection 74 abuts against the holding segment 614d, the counter gear 61 ascends along the rotation axis L2 to the maximum, at this time, the cylindrical end surface 615b reaches above the supporting surface, that is, the cylindrical circumferential surface 615a is no longer clamped by the first acting element 71 and the second acting element 72, and the manner of engaging the cylinder 615 with the control assembly 7 is changed as follows: the cylindrical end surface 615b is supported by the support surface of the control unit 7, and the guide projection 74 reaches the critical point of the holding section 614d and the translating section 614a, under the support of which the counter gear 61 is not moved along the rotation axis L2 in the direction approaching the control unit 7 (housing 1), and the counter gear 61 completes the counting process and is located at the third position.
In said third position, the tendency of the first acting element 71 to rotate in the direction r3 'and the tendency of the second acting element 72 to rotate in the direction r3 are no longer stopped by the cylinder 615, and under the action of the second reset element 73, the first acting element 71 continues to rotate in the direction r 3', and the second acting element 72 continues to rotate in the direction r3 until the reset force of the second reset element 73 is released, or the first extension 7121 of the first acting element 71 and the second extension 7221 of the second acting element 72 abut against each other, while the intermediate gear 8 remains engaged with the full pinion 612, i.e. after the counting device 6 has completed, the counter gear 61 still rotates with the rotation of the intermediate gear 8, and the toggle protrusion 613 remains engaged with the toggle lever.
Generally, the toggle protrusion 613 is arranged on a partial circumference along the circumferential direction of the main body 611, and when the counter gear 61 is in the third position, in order to ensure that the counter gear 61 can always be kept coupled to the toggle lever, along the rotation axis L2, the holding section 614d in the present invention is arranged farther from the toggle protrusion 613 than the translating section 614a, and there is a height difference therebetween, which has a value at least corresponding to the height value at which the toggle protrusion 613 protrudes from the main body 611, and for this reason, even if the counter gear 61 is in the third position, the toggle protrusion 613 or the outer surface of the main body 611 is kept coupled to the toggle lever during the rotation of the counter gear 61.
According to the above description of the counting device 6 and the control assembly 7, when the counting device 6 needs to be reset, the operator only needs to apply a force to the first force receiving part 711 and the second force receiving part 721 simultaneously, which force will force the second reset member 73 to elastically deform again, the first acting member 71 rotates around the rotation axis L3 in the direction r3, the second acting member 72 rotates around the rotation axis L3 in the direction r 3' until the support surface of the control assembly 7 no longer supports the cylindrical end surface 615b, under the elastic reset force of the first reset member 61, the counting gear 61 moves along the rotation axis L2 in a direction approaching the control assembly 7 (the housing 1) until the guide protrusion 74 again abuts against the translation segment 614a, the cylinder 615 returns to a state clamped by the first acting member 71 and the second acting member 72, the movement of the counting gear 61 along the rotation axis L2 is stopped, the counting device 6 is reset, during the reset process of the counting device 6, the end cap 4 does not need to be removed, and thus, the possibility of damage to other components in the developing cartridge 10 can be greatly reduced.
