The counting assembly 5 includes a toggle piece 51, a driven body 52 and a support body 53, the toggle piece 51 is combined with the driven body 52, and the support body 53 is used to support the driven body 52 on the housing 1 or the drive end cover 11, The driving gear 44 is arranged adjacent to the driven body 52. Along the rotation direction r1, the driven body 52 has a driving portion 521 and a non-driving portion 522. When the driving gear 44 is opposite to the driving portion 521, the driven body 52 can be driven by the gear. 44 driving, when the driving gear 44 is opposite to the non-driving part 522, the driven body 52 cannot be driven by the driving gear 44, preferably, the driving part 521 is set as teeth that can mesh with the driving gear 44, and the non-driving part 522 is set as The tooth-missing portion that cannot mesh with the driving gear 44 , however, in some embodiments, the driving portion 521 can also be configured as a rough surface or an elastic layer, and the non-driving portion 522 can also be configured as teeth that cannot mesh with the driving gear 44 .

Along the first direction, the toggle member 51 extends leftward from the driven body 52, and the support body 53 extends rightward from the driven body 52, wherein the toggle member 51 includes a base portion 51a and a toggle protrusion 51b connected to each other. The base 51a is connected to the driven body 52 or the supporting body 53, and the toggle protrusion 51b is set as at least one shrapnel/movable piece that can move in a direction intersecting with the rotation axis L5; as a simplified structure, the base 51a can be omitted , the toggle protrusion 51b is directly combined with the driven body 52 or the supporting body 53 .

After the developing cartridge C is assembled, the elastic piece 51b is located outside the driving end cover 11. During the installation and removal process of the developing cartridge C, the elastic piece 51b abuts against the inner wall of the imaging device and moves relative to the rotation axis L5, thereby, the developing cartridge C C can be installed and removed smoothly. Optionally, the shrapnel 51b is made of metal and becomes more wear-resistant, the counting assembly 5 will have a longer service life, and the shrapnel 51b made of metal can transmit the force more effectively; the shrapnel 51b can also be made of rubber It has a lower cost, and at the same time, the elastic piece 51b made of rubber can be replaced more conveniently.

The driving end cover 11 has an end cover main body 110 and a first through hole 111 and a second through hole 112 provided on the end cover main body, the driving force receiver 3 is exposed through the first through hole 111, and the counting assembly 5 is exposed through the second through hole. 112 is exposed; in some embodiments, the driving end cover 11 is further provided with a forcing protrusion 115 , and the forcing protrusion 115 is located between the first through hole 111 and the second through hole 112 along the second direction.

As shown in FIG. 5, when the developing cartridge C is installed to a predetermined position of the imaging device, the pushing protrusion 115 abuts against the first protrusion 91 of the detection part, and the imaging device detects the movement of the first protrusion 91 to judge that the developing The cartridge C has been installed, and then the driving force receiver 3 receives the driving force of the imaging device and starts to rotate around the rotation axis L, the driving part 521 is opposite to the driving gear 44, and the driven body 52 of the counting assembly starts to rotate around the rotation axis L through the gear set. The rotation axis L5 rotates along the direction shown by r1, and then the toggle member 51/pushing protrusion 51b connected to the driven body 52 starts to rotate counterclockwise in FIG. It is detected that at the same time, the first protrusion 91 and the pushing protrusion 115 are separated from each other, and after the toggle protrusion 51b has passed the second protrusion 92, the first protrusion 91 returns to the position where it abuts against the pushing protrusion 115 again. The driving part 522 is opposite to the driving gear 44, and the counting assembly 5 finishes counting and remains stationary.

During the counting process of the counting assembly 5, the plane where the motion locus of the counting assembly 5/pushing member 51/driven body 52 is perpendicular to the first direction, like this, the counting assembly 5/pushing member 51/driven body 52 does not It is necessary to make a telescopic movement relative to the housing 1 along the rotation axis L5.

With the rotation of the driving gear 44, the triggering part 445 touches the triggered part 55, the counting assembly 5 rotates an angle, and the driving part 521 Begin to be opposite to driving gear 44, subsequently, counting assembly 5 can be driven by driving gear 44 and start counting, thereby, the time-delay function of counting assembly 5 is realized, starts to rotate with driving gear 44 from trigger piece 445 to trigger piece 445 touches. The time elapsed during which the driving part 521 is opposed to the driving gear 44 when the triggered part 55 is touched is the time delay obtained by the counting assembly 5 .

Preferably, the elastic pieces in the toggle protrusion 51b are arranged in multiples separated from each other. During the installation and removal process of the developing cartridge C, among the multiple elastic pieces 51b arranged separately from each other, only the elastic pieces that interfere with the inner wall of the imaging device will be elastic. The shrapnel that is deformed and does not interfere with the inner wall of the imaging device remains in its original shape. Generally, the resistance from the inner wall of the imaging device that the counting assembly 5 receives can be reduced. On the other hand, when the shrapnel 51b contacts the second protrusion 92 Among them, the plurality of elastic pieces 51b arranged apart from each other abut against the second protrusions 92 respectively, and generally, the reaction force received by the counting assembly 5 from the second protrusions 92 can also be reduced.

During the counting process of the counting assembly E5, the movable part E52 is driven by the driven body E51 to interact with the detection part 9 in the imaging device, and the counting assembly E5 completes the counting , according to the requirements of the imaging device, the driven body E51 is no longer in contact with the movable member E52 or remains in contact.

In some embodiments, the driven body E51 is configured to include a gear body E511, a tooth portion E512 and a tooth-missing portion E513 arranged along the circumferential direction of the gear body E511, and a toggle portion E514 and a limiter arranged on the gear body E511 The counting teeth of the protrusion (an embodiment of the abutment part) E515, at least the toggle part E514 is exposed through the second through hole E32, and the limit protrusion E515 and the toggle part E514 are arranged at intervals along the circumferential direction of the gear body E511. When the counting teeth When E51 is driven by the driving gear E41 adjacent to it, the driven body E51 rotates around the rotation axis L5 parallel to the rotation axis L; in other embodiments, the rotation axis L5 can also be set to be perpendicular to the rotation axis L or Intersect, the driven body E51 can also be a part that does not include the gear body E511; further, the counting assembly E5 also includes a fixing part E53 for fixing the driven body E51, preferably, the fixing part E53 is a screw, and the screw E53 is used to fix the driven body E51 along its rotation axis, that is, under the action of the screw E53, the driven body E51 cannot move along its rotation axis L5, but can only rotate around the rotation axis L5.

The movable part E52 can be toggled by the toggle part E514 to interact with the detection part E9. Therefore, the structure of the movable part E52 can have multiple transformations. For example, the movable part E52 is a movable rod E521 as shown in FIG. The combination of the movable part E522, when the toggled part E522 is toggled by the toggled part E514, the toggled part E522 drives the movable rod E521 to move, thereby realizing the interaction between the movable rod E521 and the detection part E9, or the movable part E52 is a rotating body that can rotate around the axis, and is also provided with a dialed part and an action part for interacting with the detection part 9. When the dialing part E514 dials the dialed part E522, the movable part E52 rotates, Furthermore, the action part interacts with the detection part 9 .

In comparison, the structure of the active part set as the movable rod E521 is simpler, and it is more beneficial to control the size of the developing cartridge C. The following description takes the movable rod E521 as the active part as an example.

For this reason, as shown in Figure 7 and Figure 8, the developer cartridge C also includes a guide groove E323 adjacent to the second through hole E32, and the movable rod E521 passes through the guide groove E323, and according to the detection part 9 relative to the movable rod The position of E521, the movable rod E521 can be set such that, under the guidance of the guide groove E323, the movable rod E521 slides reciprocally in a direction substantially parallel to or intersecting with the installation direction A, but the moving direction of the movable rod E521 is not Parallel to the first direction, but intersecting with the first direction, preferably, the plane where the motion direction/trajectory of the movable rod E521 is perpendicular to the first direction, and the plane where the motion track of the driven body E51 is also parallel to the first direction vertical.

As shown in Figure 9A and Figure 9B, before the counting assembly E5 starts counting, the tooth part E512 meshes with the drive gear E41, and the limit protrusion E515 is close to the second limit surface E3242. Reverse rotation, the possible reverse rotation of the driven body E51 can also be stopped by the second limiting surface E3242, when the driving force receiver E4 receives the driving force, the driving gear E41 is driven, correspondingly, along the rotation direction r1, the driven body E51 is driven. At this time, the driven part E522 of the movable part E52 is located on the rotation path of the driven body E51. More specifically, the driven part E522 is located on the rotation path of the toggle part E514. With the rotation of E51, the toggle part E514 gradually approaches the toggled part E522, and pushes the toggled part E522 to drive the movable rod E521 to move roughly along the moving direction, thus, the movable rod E521 interacts with the detection part 9 in the imaging device .

When the toggle part E514 is out of contact with the toggled part E522, according to the needs of the imaging device, the movable lever E521 resets or remains in the state of interacting with the detection part 9. When the movable lever E521 needs to be reset, the movable lever E521 The restoring force can be from the elastic force generated after elastic deformation of the elastic member in contact with the toggled part E522 or the elastic force produced by the deformation of the toggled part 522 itself, especially when the movable rod E521 and the detection part 9 need more In the developing cartridge C, which requires only one interaction to complete counting, the movable part E52 involved in this embodiment can be effectively completed.

After the counting component E5 counts, as shown in Figure 10A and Figure 10B, the missing tooth part E513 is opposite to the drive gear E41, at this time, the counting tooth E51 is no longer driven and remains stationary, and the limit protrusion E515 is close to the first limit surface E3241, the position of the driven body E51 is effectively maintained.

After the developing cartridge C is injected with new toner, the driven body E51 needs to be reset. At this time, the operator or end user only needs to continue to push the toggle part E514 along the rotation direction r1, so that the limiting protrusion E515 presses the limiting part E324, the limiting portion E324 drives the elastic arm E322 to elastically deform in a direction away from the rotation axis L5 (outside the second through hole E32), and the limiting protrusion E515 passes over the limiting portion E324, thus, the limiting protrusion E515 returns to the second limiting position. The surface E3242 is close to the position to reset, and under the elastic action of the elastic arm E322, the restricting part E324 is reset, that is, the restricting part E324 moves from a position away from the rotation axis L5 to a position close to the rotation axis L5.

As mentioned above, when the driven body E51 in this embodiment needs to be reset, it is not necessary to disassemble the end cover E3, and the operator or end user applies a hand or tool to the toggle part E514 through the second through hole E32 to make it reset. The force of movement along the rotation direction r1 is sufficient until the limiting protrusion E515 passes over the limiting portion E324. This reset method is easy to operate and is conducive to improving the user experience of the end user.

Same as in Embodiment 2, when the imaging device is set so that when the developer cartridge C is installed to a predetermined position, the first protrusion 91 of the detection part needs to be abutted, as shown in FIG. 7 , the end cover E3 is also provided with The forcing protrusion E115 that can abut against the first protrusion 91 .

Figure 15A is a side view of the counting assembly in the developing cartridge according to Embodiment 3 of the present invention when it is observed along the rotation axis of the power receiver; Figure 15B is a side view of the embodiment of the present invention The state diagram of the relative position of the counting tooth and the driving tooth when the counting component in the developing cartridge involved in the third example finishes counting.

The same parts as in the second embodiment will be given the same numbers. The difference from the second embodiment is that in this embodiment, the driven body E51 is no longer provided with a limiting protrusion E515, and the limiting part E324 located in the end cover E3 is directly connected to the dial The moving part (another embodiment of the abutting part) E514 abuts to restrict the rotational movement of the driven body E51.

Still taking the driven body 51 as the counting tooth as an example, as shown in Figure 11A, the counting tooth E51 includes a gear body E511, a tooth portion (driving portion) E512 arranged along the circumferential direction of the gear body E511, and a missing tooth portion (non-driving portion). ) E513, and the toggle part E514 provided on the gear body E511. In this embodiment, the counting assembly E5 needs to be delayed during the counting process. In order to realize the delay function, the tooth portion E512 of the counting tooth E51 includes first tooth portions E5121 and The second tooth portion E5122, correspondingly, the tooth-missing portion E513 is also arranged as the first tooth-missing portion (i.e., the temporary cutting portion described below) E5131 and the second tooth-missing portion ( The official cutting part) E5232 described below, wherein the number of teeth of the first tooth part E5121 is greater than the number of teeth of the second tooth part E5122, and the specific number of teeth of the two can be set according to the specific counting requirements. In this embodiment, the second tooth part The number of teeth of the part E5122 is set to one, and along the circumferential direction of the gear body E511, the first tooth part E5121, the first tooth-missing part E5131, the second tooth part E5122 and the second tooth-missing part E5132 are arranged in sequence.

Further, in order to enable the counting tooth E51 to continue counting after the delay is completed, the counting tooth E51 also includes a triggered part/force receiving part E516 arranged on the gear body E511, and the function of the force receiving part E516 will be described below ; As shown in Figure 11B, the driving end cover E3 in this embodiment is also provided with an elastic arm E322 and a restricting part E324 connected to each other. Preferably, the elastic arm E322 is integrally formed with the extension part E321. Optionally, the elastic arm E322 It can also be formed separately from the extension part E321, and the two are combined by bonding or transition parts, as long as the elastic deformation of the elastic arm E322 relative to the end cover body E30 is not affected; further, along the rotation axis L5, the elastic arm There is no end portion between E322 and the end face E3211. At this time, the end face E3211 becomes a part of the elastic arm E322. One side of the cover body E321, in this structure, along the rotation axis L5, although the elastic arm E322 is directly exposed outside the end cover E3, it helps to speed up the reset operation of the counting tooth E51.

The limiting part E324 in this embodiment still has a first limiting surface E3241 and a second limiting surface E3242, as shown in Figure 12A and Figure 12B, before the counting assembly starts counting, the second tooth part E5122 is meshed with the drive gear E41, dialing The moving part E514 and the second restricting surface E3242 are close to each other. Compared with the second embodiment, the counting teeth E51 in this embodiment are more easily affected by the driving gear E41. However, under the restriction of the second restricting surface E3242, the counting teeth The position of E51 can be precisely maintained.

When the driving gear E41 receives the driving force from the driving force receiver E4 and starts to rotate, the counting tooth E51 is driven to rotate a first angle, and then the first tooth-missing portion E5131 is opposite to the driving gear E41, as shown in FIG. 13 , counting The tooth E51 is no longer driven and remains stationary. As the driving gear E41 continues to rotate, the trigger/force applying part E411 that moves together with the driving gear E41 begins to abut against the triggered part/force receiving part 516. Therefore, the counting tooth E51 It is dialed and continues to rotate in the direction of rotation r1. It can be seen that, after the second tooth part E5122 disengages from the driving gear E41 until the triggering part/force applying part E411 abuts against the triggered part/force receiving part E516, the counting The tooth E51 is in a static state, thus, the time-delay function of the counting tooth E51 is realized.

It can be understood that the position of the triggered part/force receiving part E516 on the gear body E511 need not be limited, as long as the triggered part/force receiving part E516 can abut against the triggered part/force applying part E411. Preferably, The triggered part E516 is opposite to the first tooth-missing part/temporary cut-off part E5131. Parameters such as the duration and number of contact between the force-applying part E411 and the force-receiving part E516 can be determined according to the delay requirements of the counting tooth E51. For example, when the counting tooth When the delay time required by E51 is longer, the arc length of the first tooth-missing part E5131 can be set larger, at least after the force-applying part E411 contacts the force-receiving part E516 once, the first tooth-missing part E5131 is still in contact with the force-receiving part E516 The drive gear E41 is opposite. When the delay time required by the counting tooth E51 is shorter, the position of the force applying part E411 on the drive gear E41 can be adjusted so that the force applying part E411 can contact the force receiving part E516 earlier.

After the first tooth part E5121 meshes with the driving gear E41, as shown in Figure 14A and Figure 14B, as the driving gear E41 continues to rotate, the toggle part E514 gradually approaches the toggled part E522, and by pushing the toggled part E522 Drive the rod body E521 to move in a direction roughly parallel to the installation direction A, so that the rod body E521 interacts with the detection component 9; as shown in Figure 15A and Figure 15B, when the second tooth-missing part E5132 is opposite to the driving gear E41, the counting component E5 After counting is completed, the counting teeth E51 will not be driven by the continuously rotating drive gear E41 and remain stationary. At this time, the toggle part E514 reaches a position close to the first restricting surface E3241. Under the restriction of the first restricting surface E3241, the counting teeth The slight rotation of E51 due to vibration can be effectively stopped.

In this embodiment, the angle through which the counting gear E51 rotates is called the second angle during the process from the first tooth portion E5121 meshing with the driving gear E41 until the second missing tooth portion E5132 is opposite to the driving gear E41. The second angle is greater than the first angle.

When the developing cartridge C is injected with new toner, the driven body E51 needs to be reset. Similarly, the operator or end user only needs to apply force to the toggle part E514 along the rotation direction r1, so that the toggle part E514 goes beyond the limit After reset, the second tooth part E5122 of the counting tooth E51 meshes with the drive gear E41 again, and in this process, the elastic arm E322 drives the restricting part E324 to the direction away from the rotation axis L5 (the second through hole E32 radial outward direction), when the toggle part E514 passes over the restriction part E324, the elastic arm E322 drives the restriction part E324 to reset.

Same as the second embodiment, when the counting tooth E51 in this embodiment needs to be reset, there is no need to disassemble the end cover E3, only need to push the counting tooth E51 to continue to rotate along the rotation direction r1 until the toggle part E514 and the second limit The surface E3242 can be close. Further, the elastic arm E322 in this embodiment is directly exposed outside the end cover E3. When the resistance of the restricting part E324 to the toggle part E514 is large, the operator or end user can manually The manner of pressing the restricting part E324 enables the toggle part E514 to quickly pass over the restricting part E324.

Based on the above inventive concept, the abutting portion E515/E514 that is close to the restricting portion E324 is provided in the counting tooth E51. It plays the role of indicating the initial position of the counting tooth E51. After the counting is completed, the abutment part E515/E514 and the first restricting surface E3241 are close to each other, which can prevent the counting tooth from continuing to rotate. E51 exerts an active force, so that the counting tooth E51 continues to rotate along the rotation direction r1 until the abutment part E515/E514 reaches the position close to the second restricting surface E3242 again. Therefore, without considering the delay, the implementation The structure of the counting tooth and the structure of the restricting part in Example 2 and the structure of the counting tooth and the structure of the restricting part in Embodiment 3 are interchangeable.

It can be understood that the toggle part E514 in this embodiment can be replaced by the toggle protrusion 51b in the first embodiment; the situation where the counting tooth E51 is integrally formed is described above, however, those skilled in the art can also realize that counting The tooth E51 is formed separately. At this time, the tooth part and the toggle part E514 for receiving the driving force from the drive gear E41 are separately arranged. When counting, the tooth part and the toggle part E514 are combined with each other. When the counting is completed, the tooth part Disengaged from the toggle part E514, in this case, even if the counting tooth E51 continues to rotate without a missing tooth part, the toggle part E514 remains still. At this time, the fixing part E53 is only used to limit the toggle part E514 Move along the rotation axis L5; achievably, the position of the elastic arm E322 can be set arbitrarily in the end cover E3, as long as it is ensured that the restricting part connected with the elastic arm E322 can limit the abutting part, in some embodiments In this case, the extension part E321 may not be provided.

For example, when two types of developing cartridges have only a slight difference in the position of the first pushing portion 14a, the casing 1 can be used in common, and the production mold of the developing cartridge can be simplified, thereby reducing production costs and management costs; or , when a certain type of developing cartridge needs a larger forcing force, a reinforcing part that can strengthen the strength of the first forcing part 14a can be set in the empty area.

On the other hand, the driving gear 44 only needs to be arranged in one stage, and it is arranged close to the left side wall 1a1, and the diameter of the driving gear 44 and the size in the left and right directions are all reduced; in this embodiment, the first forcing part 14a is arranged On the driving end cover 11, along the left-right direction, the overlapping area between the first forcing portion 14a and the driving gear 44 can be reduced, or even no overlapping area occurs. During the assembly process of the developing cartridge C, the driving end cover 11 and the driving gear 44 The interference between them can be reduced or eliminated; in the following embodiments, when the first forcing portion 14a protrudes from the left side wall 1a1, there is no gap between the reduced-diameter driving gear 44 and the first forcing portion 14a. Interference occurs, that is, there is no overlap between the first forcing portion 14 a and the driving gear 44 on a plane perpendicular to the left-right direction.

In actual work, the counting assembly 5 needs to be disengaged from the driving gear 44 to keep still after the counting is completed, and the driven body 52 is set as a "half-toothed gear" having a tooth-missing part 522 (as shown in Figure 23 ) and a tooth part 521. ” is the first way. During the counting process, the tooth portion 521 is opposite to the driving gear 44. When the counting is completed, the missing tooth portion 522 is opposite to the driving gear 44; the driving body 52 is set to a full-toothed gear (as shown in FIG. 21B ), Simultaneously, it is the second way to set the driving member 51 and the driven body 52 to be combined in a detachable manner. When counting, the driving member 51 can receive the driving force of the driven body 52. When the counting is completed, the driving member will 51 is disengaged from the driven body 52; at least one of the driving gear 44 and the driven body 52 is set to move along the moving direction intersecting with the left and right direction is the third way. During the counting process, the driving gear 44 and the driven The bodies 52 are combined with each other. When the counting is completed, at least one of the driving gear 44 and the driven body 52 moves in the moving direction so that the two are disengaged.

The above-mentioned first method puts forward higher requirements on the manufacturing accuracy of the driven body 52, and the second method needs to set the toggle member 51 and the driven body 52 into separate forms, which will not only make the assembly process complicated, but more importantly It is not conducive to maintaining the working stability of the counting assembly 5. When the third method is adopted, preferably, the drive gear 44 is set to move in the moving direction, and more preferably, the moving direction is orthogonal to the left-right direction At the same time, since the driving gear 44 and the first forcing part 14a are also separated from each other, as shown in Figure 21B, a space S4 is formed between the driving gear 44 and the first forcing part 14a, so the driving gear 44 can With more space, the device capable of moving the drive gear 44 will have greater design freedom.

It should be noted that no other parts are set in the above-mentioned vacant area and the space area, which means that there are no functional parts, such as protrusions or slide grooves used to support a certain part, but are set due to the mold requirements of the product. Protrusions or grooves are allowed.

(embodiment five)

The difference between this embodiment and the fourth embodiment is that when the driving force is transmitted from the conductive end 104 to the driving end 103, the powder feeding part 23 is no longer used, but a transmission shaft 24 parallel to the powder feeding part 23 is used. The rotation axis L24 of the transmission shaft 24 is also parallel to the rotation axis of the developing member 21 . Preferably, along the front-to-back direction, the transmission shaft 24 is closer to the front 101 than the powder feeding member 23 , and the drive gear 44 is coaxially arranged with the transmission shaft 24 , but there is still a gap S20 between the drive gear 44 and the first gear 41 .

As shown in Figure 22, the driving gear 44 is separated from the driven body 52 in the counting assembly, and the driving gear 44 is set to move in the moving direction. Before the developing cartridge C is installed, the driving gear 44 and The driven body 52 is separated from each other, so that the driving gear 44 will neither touch the first gear 41 nor the driven body 52 during transportation of the developing cartridge C, thereby reducing the size of the driving gear 44. , the first gear 41 and the risk of being damaged by the driven body 52; during the process that the developing cartridge C is installed or when the developing cartridge C is installed to a predetermined position and starts to work, the driving gear 44 returns to be combined with the driven body 52 position, so that the counting assembly 5 can receive the driving force required for counting. After the counting is completed, the driving gear 44 returns to the position separated from the driven body 52 again.

Similarly, in this embodiment, the drive gear 44 only needs to be provided with one stage, and a space S4 will also be formed between it and the first forcing portion 14a. The device capable of moving the drive gear 44 will have greater design freedom.

As an alternative, it is possible to control whether the transmission shaft 24 transmits the driving force from the conductive end 104 to the driving end 103 according to the stage of the counting assembly 5. When the counting assembly 5 needs to count, the transmission shaft 24 can transmit the driving force From the conductive end 104 to the driving end, when the counting assembly 5 counts, the transmission process of the transmission shaft 24 is cut off, and the cutting can be carried out at any position of the transmission shaft 24, or between the transmission shaft 24 and its left gear or between the transmission shaft 24 and its right side gear.

In this embodiment, the driving force transmission between the driving force receiver 3/first gear 41/third gear 43 directly as the driving part or provided with the driving part and the driving gear 44 as the driven part is replaced by a gear The rod 16 , that is, in this embodiment, the transmission mechanism is a gear rod 16 . As shown in the figure, the gear rod 16 includes a rod body 163 and a first joint part 161 and a second joint part 162 respectively located at both ends of the rod body 163. The driving gear 44 is combined, and the rod body 163 is not in contact with the first forcing part 14a; similarly, the rotation axis of the gear rod 16 and the rotation axis of the driving part can be perpendicular to each other, or can be in an angle shape, as long as the gear rod 16 can drive The force can be transmitted from the active part to the driven part. Preferably, the rotation axis of the gear rod 16/rod body 163 is perpendicular to the rotation axis of the active part. In the following, the combination of the first coupling part 161 and the first gear 41 is taken as an example. describe.

Fig. 29 is a side view of the driving end of the developing cartridge according to the ninth embodiment of the present invention viewed from above; Fig. 30 is a side view of the driving end of the developing cartridge according to the ninth embodiment of the present invention viewed from below.

The difference from the eighth embodiment is that the driving gear 44 in this embodiment is no longer provided with a positioning part 443, therefore, the driving gear 44 in this embodiment is the gear body 441 in the eighth embodiment, and the second combination of the gear rod 16 The portion 162 is combined with the drive gear 44 . The same as the eighth embodiment, there is still a gap between the first gear 41 and the driving gear 44, and the first pushing part 14a is completely located in the gap, and at the same time, there is also a gap between the first pushing part 14a and the driving gear 44.

As mentioned above, the process of transmitting the driving force from the driving force receiving member 3 to the driving gear 44 is no longer realized by the gear arranged between the driving force receiving member 3 and the driving gear 44. The driving gear 44 in the invention may be inconsistent with the predetermined rotational speed, or in other words, the rotational speed of the driving gear 44 may be faster or slower than the predetermined rotational speed, and then the counting assembly 5 may be faster or faster than the predetermined rotational speed. Slow, so that the counting assembly 5 cannot realize the counting function; or, the diameter of the counting assembly 5 is reduced to reduce its manufacturing cost, at this time, the rotation speed of the counting assembly 5 will also become faster.

For this reason, the present invention also provides a speed adjustment assembly between the drive gear 44 and the counting assembly 5, which is used to adjust the rotation speed of the counting assembly 5 when it is driven by the drive gear 44 according to the counting requirements of the counting assembly 5, and finally make the counting Component 5 is able to realize its counting function. When the rotational speed of the driving gear 44 is slower than the predetermined rotational speed, at this time, the rotational speed of the counting assembly 5 needs to be accelerated. Usually, for example, the diameter of the driving gear 44 is increased while the diameter of the driven body 52 is reduced. way can be realized.

In this embodiment, the description is made by taking the rotational speed of the driving gear 44 as an example faster than the predetermined rotational speed. At this time, the speed adjustment assembly is actually a delay device, and the delay device can be used without changing the driving gear 44. In the case of rotation speed, the average speed of the counting assembly 5 during the counting process is reduced, so that the time required for the counting assembly 5 to rotate the predetermined angle of the toggle member 51 during the counting process is lengthened.

As shown in Figure 31A and Figure 31B, in this embodiment, the counting part of the counting assembly 5 includes a toggle piece 51 and a driven piece 52 that are combined with each other. Similarly, the toggle piece 51 and the driven piece 52 can be integrated Formed, can also be formed separately, the driven part 52 is used to receive the driving force of the driven part, and then drive the toggle part 51 to rotate around the rotation axis L5 in the direction indicated by r1, and interact with the detection part in the imaging device; In this embodiment, the toggle 51 is directly or indirectly arranged on the left side surface 52a of the driven body 52. Alternatively, the toggle 51 in this embodiment can also be replaced by the toggle described in Embodiment 1. Part 51 or the movable part E52 described in the second embodiment.

The toggle member 51 includes a cylinder 510 connected to the driven body 52 and at least one counting protrusion formed by extending radially outward along the cylinder 510. During the counting process of the counting assembly 5, the counting protrusion toggles or presses the detection device in the imaging device. Part 9, in this embodiment, the toggle member 51 is provided with a first counting protrusion 511 and a second counting protrusion 512 arranged at intervals along the rotation direction r1; it can be understood that the cylinder 510 can be omitted, and the first counting protrusion 511 and the second counting protrusion 512 The second counting protrusion 512 is directly combined with the driven body 52 and rotates as the driven body 52 rotates.

The counting part also includes a triggered part 55 for driving the driven body 52 to rotate. When the driven body 52 is in a state of stopping rotation, the triggered part 55 is triggered by an external trigger 445 (as shown in FIG. 33 ). The driven body 52 continues to rotate. Preferably, the triggered part 55 is a force-bearing protrusion combined with at least one of the driven body 55 and the support body 53. More preferably, the triggered part 55 is combined with the driven body 55 and the support body 53 at the same time, and the triggered part 55 protrudes radially outward from the peripheral surface of the support body 53 , but the triggered part 55 does not protrude beyond the driven body 52 , preventing unnecessary interference of the triggered part 55 . When the counting portion is configured to rotate about a rotation axis, the counting portion further includes a sleeve 54 combined with the driven body 52 and extending from the right side surface 52b of the driven body 52 along the rotation axis L5.

The driven body 52 is configured as a rotating body rotatable around the rotation axis L5, and the driving part 521 and the non-driving part 522 are arranged along the circumferential direction of the rotating body, wherein the driving part 521 is used to receive an external driving force to make the rotating body 52 rotate, The non-driving portion 522 is used to cut off the driving force transmitted to the rotating body 52, so that the rotating body 52 no longer rotates. In this embodiment, the driving portion 521 is set as a tooth portion arranged along the circumferential direction of the rotating body, and the non-driving portion 522 is set as The tooth-missing portion arranged along the circumferential direction of the rotating body.

When the counting assembly 5 and the driving gear 44 are disengaged using the first method described in Embodiment 4, the driving part 521 includes at least a first driving part 521a and a second driving part 521b arranged at intervals along the rotation direction of the rotating body , the non-driving part 522 at least includes a first non-driving part 522a and a second non-driving part 522b arranged at intervals along the rotation direction of the rotating body. When the counting assembly 5 is in the counting state, the first driving part 521a and the second driving part 521b One of the second non-driving portion 522b is opposite to the driving gear 44; when the counting assembly 5 finishes counting, the first non-driving portion 522a is opposite to the driving gear 44.

As shown in Figure 32A and Figure 32B, along the rotation direction r1 of the rotating body, the first driving part 521a, the second non-driving part 522b, the second driving part 521b and the first non-driving part 522a are arranged adjacent to each other in sequence, in the counting assembly In the counting process of 5, when the second driving part 521b is opposite to the driving gear 44, the rotating body 52 receives the driving force to rotate, and as the second non-driving part 522b is facing the driving gear 44, the rotating body 52 no longer receives the driving force and starts to rotate. stop the rotation, therefore, the second non-driving portion 522b can be regarded as an embodiment of the temporary cut-off portion, which is used to temporarily cut off the driving force transmission between the drive gear 44 and the rotating body 52; When triggered by an external component, the rotating body 52 starts to rotate again until the first driving part 521a is opposite to the driving gear 44, and then the rotating body 52 continues to rotate. When the first non-driving part 522a is opposite to the driving gear 44, the counting assembly 5 After counting is completed, the rotating body 52 remains stationary, and the first non-driving portion 522a can be regarded as an embodiment of a formal cut-off portion, which is used to completely cut off the driving force between the driving gear 44 and the rotating body 52 Transferring, regardless of whether the drive gear 44 continues to rotate, the rotating body 52 remains stationary.

Regarding the position of the triggered part 55, based on the inventive concept of the present invention, when the triggered part 445 triggers the triggered part 55, the triggered part 55 can drive the rotating body 52 to start rotating again; as a preferred method, When viewed along the rotation axis L5, the triggered part 55 is opposite to the second non-driving part 522b. More preferably, along the rotation direction r1, the triggered part 55 is approximately located in the middle of the arc corresponding to the second non-driving part 522b. The position can ensure that the first driving part 521a and the driving gear 44 can mesh smoothly when the triggered part 55 is triggered.

The driving gear 44 of the powder feeding part includes a main body 440, teeth 441 arranged along the circumferential direction of the main body, a D-shaped part 444 located in the main body 440, and a trigger 445 extending radially outward along the circumferential surface of the main body. The powder feeding part 23 or the transmission shaft 24 is combined with the D-shaped part 444 , thus, the driving gear 44 can obtain the driving force transmitted from the powder feeding part 23 or the transmission shaft 24 ; the triggering part 445 is set as an extended protrusion capable of pushing the triggered part 55 .

Before describing the working process of the counting assembly, first describe the structure of the second counting protrusion 512 involved in this embodiment with reference to Figure 31A and Figure 32A, as shown in the figure, along the rotation direction r1, the first counting protrusion 511 and the second counting protrusion 512 are arranged at intervals, and the second counting protrusion 512 is formed as a fan-shaped extension, with an upper side plate 5121 located upstream, a lower side plate 5122 located downstream, and an arc-shaped plate 5123 located between the upper side plate and the lower side plate. The arc-shaped plate 5123 has a front end point 512a located at the upstream end and a rear end point 512b located at the downstream end. The radially outer side of the arc-shaped plate 5123 forms an arc-shaped surface 512c with an arc length of m.

The counting process of the counting assembly 5 is described below in conjunction with FIGS. 34A-34F . In order to describe the working process of the counting part more clearly, only the driving gear 44 and the counting part are shown in the figure.

When the developing cartridge C is installed to the imaging device but has not yet started to work, the counting projection and the detection part 9 in the imaging device may or may not be in contact with each other. However, regardless of the relative positions of the pushing protrusion 115 described in Example 1, the speed adjustment assembly involved in the present invention is applicable. In Fig. 34A, before the developing cartridge C starts to work, the first counting protrusion 511 corresponding to the pushing protrusion 115 abuts against the detection member 9, and the teeth 441 of the driving gear 44 mesh with the second driving part 521b. When the driving force When the driving force of the receiving part 3 makes the driving gear 44 start to rotate in the direction indicated by r2, the rotating body 52 is driven to rotate in the direction indicated by r1, and the detection component 9 interacts with the first counting protrusion 511 continuously.

As shown in Figure 34B, when the first counting protrusion 511 moves to disengage from the detection part 9, the detection part 9 starts to abut against the front end point 512a of the second counting protrusion 512, and the driving gear 44 is connected to the second non-driving part/disengagement. At this time, the rotating body 52 remains stationary, and correspondingly, the second counting protrusion 512 keeps abutting against the detection component 9 all the time. During the meshing process of the driving gear 44 and the second driving part 521b, both the triggering part 445 and the triggered part 55 move toward the area where the driving gear 44 is opposite to the rotating body 52, but the triggering part 445 arrives at the said part before the triggered part 55. Therefore, the triggered part 55 will not interfere with the triggering part 445 .

As the driving gear 44 continues to rotate in the direction shown by r2, as shown in FIG. 34C, along the rotation direction r1, the triggering member 445 reaches the upstream of the triggered member 55, and then, the triggered member 55 is triggered, and the rotating body 52 starts to move again. Rotate in the direction shown by r1, as shown in Figure 34D and Figure 34E, the driving gear 44 starts to mesh with the first driving part 521a, and the arc surface 512c abuts against the detection part 9 until the driving gear 44 is in contact with the first non-driving part/formally The cut-off portion 522a is opposite, as shown in FIG. 34F , the counting assembly 5 finishes counting and stops rotating, and the driving gear 44 still rotates in the direction shown by r2. At this time, the detection member 9 is out of contact with the rear end point 512b of the second counting protrusion 511.

When the driving gear 44 begins to face the cut-off portion 522b or when the driving gear 44 just disengages from the second driving portion 521b, the trigger member 445 is located at the first position shown in FIG. When starting to trigger the triggered member 55, the triggering member 445 is located at the second position shown in FIG. and the trigger member 445 at the second position are shown in FIG. 34C, wherein the dotted line indicates the trigger 445 at the first position, and the solid line indicates the trigger 445 at the second position. Along the rotation direction r1, the triggering member 445 at the two positions are respectively located on both sides of the triggered member 55, and along the rotation direction r2, when the triggering member 445 rotates from the first position to the second position, the rotation angle is β, β<360°, the second counting protrusion 512 is always in contact with the detection component 9 , which simulates the process of the detection component 9 interacting with the second counting protrusion 512 all the time.

During the meshing process of the driving gear 44 and the first driving part 521a, the detecting part 9 abuts against the arc-shaped surface 512c, and when the driving gear 44 is about to reach the position opposite to the first non-driving part 522a, the detecting part 9 reaches At the rear end point 512b of the arcuate surface 512c, when the driving gear 44 is facing the first non-driving portion 522a, the detecting member 9 is out of contact with the arcuate surface 512c, and at this moment, the counting is completed.

It can be seen from this that, in this embodiment, the time period for the detection member 9 to abut against the second counting protrusion 512 is equal to the time period required for the rotation angle α of the driving body 52 (as shown in FIG. 32A ) and the time period required for the rotation angle β of the driving gear 44. The sum of time lengths, wherein, the angle α is the angle between the front end point 512a and the rear end point 512b, corresponding to the arc length of the arc plate 5123 extending along the direction indicated by r1, and the angle β corresponds to the rotation of the trigger member 445 from the first position to the second position The arc length corresponding to the second position. For existing counting pieces, the time during which the second counting projection 512 in this embodiment abuts against the detection member 9 is extended, and the extended time length is the time length required for the drive gear 44 to rotate the angle β. Therefore, the second The second non-driving part/temporary cut-off part 522b can be regarded as an embodiment of the delay device, and the temporary cut-off part 522b is used to temporarily cut off the driving force received by the rotating body 52, so that the rotating body 52 remains stationary to realize time delay; The triggered part 55 is used to be triggered by the external trigger part 445, so that the rotating body 52 obtains the driving force to rotate again, so the triggered part 55 can be regarded as an embodiment of the restarting device; The process between cutting off the driving force and obtaining the driving force again is a delay stage. In this delay stage, the counting assembly 5 is still in the counting state, specifically, the detection part 9 remains in contact with the second counting protrusion 512; thus, Even if the rotation speed of the driving tooth 44 becomes faster, the purpose of ensuring the counting function of the counting assembly 5 can be achieved without changing the structure of the second counting protrusion 512 .

For the second driving part 521b, before the developing cartridge C starts to work, the tooth 441 of the driving gear is in the position combined with the upstream end of the second driving part 521b, which is more conducive to reducing the arc length of the second driving part 521b, and when When the tooth 411 is disengaged from the downstream end of the second drive part 521b, the detection member 9 has at least disengaged from the first counting protrusion 511, or has reached the position of abutting against the second counting protrusion 512, that is to say, the second counting protrusion 512 has been abutted against. The arc length of the driving portion 521b is at least sufficient to allow the first counting protrusion 511 to rotate to disengage from the detection component 9 . When the second driving part 521b is a tooth, the number of teeth is at least 6, so that when the driving gear 44 is disengaged from the second driving part 521b or in other words when the driving gear 44 is opposite to the cutting part 522b, the first counting protrusion 511 It is disengaged from the detection part 9. Preferably, the number of teeth is at least 7, which can prevent the detection part 9 from being disengaged from the first counting protrusion 511 due to manufacturing errors, but the detection part 9 cannot reach the second counting protrusion. The position where 512 abuts, that is to say, the position accuracy requirements of the first counting protrusion 511 and the second counting protrusion 512 are lowered.

Based on the technical concept of the present embodiment, setting the delay device on the rotating body 52 can achieve the purpose of slowing down the rotation speed of the counting assembly 5/rotating body 52/counting protrusion 511/512, thereby ensuring that the counting function of the counting assembly 5 can be accomplish.

When only one trigger 445 is provided and the relative position of the drive gear 44 is constant, the position and shape of the counting protrusion can be set according to the total duration and/or interval duration of the detection part 9 being abutted according to the counting process of the counting assembly 5 , For example, when the total duration of the second counting protrusion 512 abutting against the detection component 9 in this embodiment needs to be further increased/decreased, it can be realized by extending/shortening the arc length of the arc surface 512c; when the second counting protrusion 512 in this embodiment When the total duration of a counting protrusion 511 abutting against the detection component 9 needs to be increased, an arc surface that can abut against the detection component 9 can be provided on the first counting protrusion 511, and correspondingly, the number of teeth of the second driving part 521b needs to be increased , or by shortening the arc length of the second driving part 521b. At this time, the temporary cutting part 522b has been opposed to the driving gear 44, but the first counting protrusion 511 is still in contact with the detection part 9. It can also be used in the second driving The upstream of the part 521b is provided with a temporary cut-off part, so that the driving gear 44 is equivalent to idling until the trigger part 445 triggers the triggered part 55. Further, if the total duration of the second counting protrusion 512 abutting against the detection part 9 does not need to be changed, the second Between the first driving part 521a and the second driving part 521b, there is no need to set up a temporary cutting part in addition, the first driving part 521a and the second driving part 521b are connected as one, and the driving gear 44 is connected with the first driving part 521a and the second driving part 521a. The two driving parts 521b are combined until the counting is completed, at this time, only one driving part and one formal cutting part are arranged on the circumference of the rotating body 52 .

When the shape of the counting protrusion 511/512 does not change, but it is necessary to reduce the length of time the counting protrusion abuts against the detection part 9, one or more triggers can be additionally set on the drive gear 44, and when the drive gear 44 rotates, the The trigger part provided in addition will trigger the said triggered part 55 earlier than the trigger part 445 in this embodiment, and the rotating body 52 can also switch from the state of temporarily cutting off the driving force to the state of receiving the driving force again earlier. , the total time period during which the second counting protrusion 512 abuts against the detection component 9 can be reduced.

For the toggle member 51 with multiple counting protrusions, if it is necessary to control the length of the interval between two adjacent counting protrusions abutting against the detection component 9, it can be achieved by reducing the arc length of the second driving part 521b, At this time, the time during which the second driving part 521b receives the driving force from the driving gear 44 becomes shorter, that is to say, the arc length of the second driving part 521b only needs to ensure that the previous counting protrusion rotates until it disengages from the detection member 9. , without making the latter counting protrusion reach the position where it abuts against the detection component 9 .

(Embodiment Eleven)

On the basis of the tenth embodiment, this embodiment will further describe the counting part provided with multiple temporary cut-off parts, that is to say, the delay device in this embodiment includes multiple temporary cut-off parts. As shown in Figure 35, the structure of the toggle member 51 remains unchanged in this embodiment, but two temporary cut-off parts are provided on the rotating body 52, and the total counting time of the toggle member 51 is longer, therefore, this embodiment also It can be regarded as another implementation manner of prolonging the total contact time between the second counting protrusion 512 and the detection component 9 in the tenth embodiment.

Along the rotation direction r1, the rotating body 52 includes a first driving part 521a, a second driving part 521b, a third driving part 521c, a first non-driving part 522a, a second non-driving part 522b and a third non-driving part 522c, when counting When the assembly 5 is in the counting state, the driving gear 44 is opposite to at least one of the first driving part 521a, the second driving part 521b, the third driving part 521c, the second non-driving part 522b and the third non-driving part 522c, when the counting assembly When the counting is completed, the driving gear 44 is opposite to the first non-driving portion 522a, thus, the first driving portion 521a, the second driving portion 521b, the third driving portion 521c, the second non-driving portion 522b and the third non-driving portion 522c The area where it is located can be called the counting area of the rotating body 52, and the area where the first non-driving part 522a is located can be called the non-counting area of the rotating body 52; similarly, for the tenth embodiment, the first driving part 521a , the second driving part 521b, and the second non-driving part 522b can be called a counting area, and the first non-driving part 522a can be called a non-counting area. Along the rotation direction of the rotating body 52, counting The area and the non-counting area are adjacently arranged on the circumference of the rotating body.

It should be noted that the counting area and the non-counting area here are divided according to whether the counting assembly 5 is in the counting state, rather than according to the shape or arc length of each driving part and non-driving part, that is, That is to say, even if the arc length of the first driving part 521a is set, the counting assembly 5 has finished counting, but the driving gear 44 is still facing/engaging with the first driving part 521a, so the first driving part 521a has not yet been opposite to the driving gear 44 The over/engaged portion should still be regarded as a part of the first non-driving portion 522a.

In the counting area, along the rotation direction r1, the second driving part 521b, the second non-driving part 522b, the third driving part 521c, the third non-driving part 522c and the first driving part 521a are arranged sequentially from upstream to downstream, when driving When the gear 44 is opposite/engaged with the second driving part 521b, the third driving part 521c and the first driving part 521a, the rotating body 52 can receive the driving force and rotate. When the driving parts 522c are opposed/engaged, the rotating body 52 cannot receive the driving force and remains stationary. Therefore, the second non-driving part 522b and the third non-driving part 522c can be regarded as a first temporary cut-off part and a second temporary cut-off part, respectively. .

As shown in Figure 35, the restarting device in this embodiment includes a first triggered part 55 and a second triggered part 56 opposite to the first temporary cut-off part 522b and the second temporary cut-off part 522c respectively, wherein the first The triggered part 55 is used to make the rotating body 52 rotate again to drive gear 44 and the third driving part 521c to be opposite/engaged after being triggered, and the second triggered part 56 is used to make the rotating body 52 rotate again to drive after being triggered. The gear 44 is opposite/engaged with the first driving part 521a, and the third driving part 521c is located between the first triggered part 55 and the second triggered part 56 along the rotation direction r1.

As mentioned above, the counting area in this embodiment is provided with a plurality of temporary cut-off parts, so that during the counting process of the counting assembly 5, the total duration of the abutment/non-abutment between the counting protrusion and the detection member 9 is elongated, The counting function of the counting component 5 is successfully realized.

(Example 12)

This embodiment is further evolved on the basis of the eleventh embodiment. The toggle member 51 in this embodiment is still provided with a first counting protrusion 511 and a second counting protrusion 512 separated from each other along the rotation direction r1, which is different from that of the embodiment In comparison, the second counting protrusion 512 is set to have the same shape as the first counting protrusion 511, instead of being an arc-shaped plate extending along the rotation direction r1. In this embodiment, for the two counting protrusions, the first The counting time length of a counting protrusion 511 is the same as the counting time length of the second counting protrusion 512, but the delay device positioned in the counting area will make the counting assembly 5 in the counting process, the first counting protrusion 511 and the second counting protrusion 512 and the detection The time interval between the abutment of the component 9 is lengthened. Therefore, this embodiment can be regarded as another embodiment for lengthening the time interval between the abutment of two adjacent counting protrusions and the detection part 9 in the tenth embodiment.

(Embodiment 13)

In this embodiment, the diameter reduction of the counting assembly 5 is used as an example for description. At this time, the diameters of the rotating body 52 and the toggle member 51 are all reduced, and the rotation speed is accelerated. It is used in the developing cartridge applicable to the counting assembly before shrinking. Similarly, the counting assembly 5 also needs to be provided with the above-mentioned delay device.

As shown in Figure 37, the first driving part 521a, the second non-driving part 522b/delay device/temporary cutting part, the second driving part 521b and the first non-driving part 522a are arranged in sequence along the rotation direction r1 of the rotating body 52 On the circumference of the rotating body 52, the second non-driving portion 522b is located between the first driving portion 521a and the second driving portion 521b. Since the rotating speed of the rotating body 52 is accelerated, when the second driving portion 521b is set as a tooth, the The number of teeth can be reduced to no less than 2, that is, when the number of teeth of the second driving part 521b is 2, as the rotating body 52 rotates from the position where the driving gear 44 is opposite to the upstream of the second driving part 521b to the driving gear 44 and the position downstream of the second driving part 521b, the first counting protrusion 511 can be disengaged from the detection part 9; due to the provision of the temporary cutting part 522b, the counting time of the counting assembly 5 is elongated.

It can be seen that the minimum number of teeth of the second driving part 521 b can vary within a range of 2-6, and the specific number can vary according to the diameter of the rotating body 52 .

When the counting assembly 5 described in the tenth to twelveth embodiments above completes the counting, the rotating body 52 no longer receives the driving force through the way that the first non-driving part 522a provided therein is opposed to/engages with the driving gear 44, that is, the embodiment For the first disengagement method described in 4, for the tenth to the twelveth embodiment, the arc length of the first non-driving portion 522a is not less than the circumference of the trigger 445 when it rotates with the driving gear 44. Therefore, when the driving gear 44 When facing/engaging with the first non-driving portion 522a, even if the driving gear 44 continues to rotate, the triggering member 445 will not trigger the triggered member 55 to cause the rotating body 52 to continue rotating.

However, when the counting assembly 5 completes counting, and the rotating body 52 and the drive gear 44 adopt the second or third disengagement method described in Embodiment 4, the specific structure of the first non-driving portion 522a will become no longer important. , at this time, the first non-driving portion 522a can be set as a tooth-missing portion as described above, or can be set as a toothed portion, but no matter how the specific structure of the first non-driving portion 522a is, the counting is completed after the counting assembly 5 , the dial 51 and the rotating body 52 are disengaged, even if the rotating body 52 is still driven to rotate by the drive gear 44, the dial 51 will remain stationary, or at least one of the rotating body 52 and the driving gear 44 intersects the left and right directions. At this time, the rotation center of the driving gear 44 and the rotation center of the rotating body 52 are far away from each other, even if the driving gear 44 continues to rotate, the rotating body 52 cannot receive the driving force and remains stationary.

[beneficial effect]

As mentioned above, when the driving force transmission method described in Embodiment 4 and Embodiment 5 is adopted, the driving force received by the driving force receiver 3 from the imaging device is first transmitted from the driving end 103 to the conductive end 104, and then from the conductive end 104 is transmitted to the driving end 103, although a gear for transmitting the driving force needs to be provided at the conductive end 104, the gear density on the side where the driving end 103 is located is effectively reduced, regardless of whether the developing cartridge C is assembled manually or machine-assembled, Gears can be installed on both sides at the same time. Compared with the gear density on the side where the driving end of the existing developing cartridge is located, and there is an overlapping structure between the gears along the left and right directions, the above-mentioned method of installing gears on both sides of the developing cartridge at the same time is reversed. Will improve assembly efficiency.

The counting assembly 5 needs to be driven when counting, and does not need to be driven when the counting is completed. When the drive shaft 24 parallel to the stirring frame 23 is used to transmit the driving force from the conductive end 104 to the driving end 103, that is to say, the counting assembly 5 The required driving force no longer comes from the powder feeding part 23, and the load of the powder feeding part 23 will not change (decrease) suddenly when it rotates, so the working stability of the powder feeding part 23 can be guaranteed. On the other hand, when the counting assembly 5 completes the counting, the driving force transmission of the drive shaft 24 can be set to be interrupted. The interruption of the driving force transmission will not affect the work of the powder feeding member 23, and the interruption position has more options, such as , the interruption position can be at the conductive end 104 or at the driving end 103 , and can also be on the body of the transmission shaft 24 .

In the embodiment of the present invention, between the driving force receiver 3/first gear 41/third gear 43 directly used as the active part or provided with the active part and the driving gear 44 directly used as the driven part or provided with the driven part A blank area S20 is formed between them. Along the front-to-back direction, the active part is located in front of the driven part, and the driving force is transmitted between the two through a non-gear combination. By adjusting the radial size of the driven body 52, correspondingly, the position of the driving gear 44 can also be adjusted in the empty area, so that the developing cartridge C can be used in multiple models.

The vacant area provides sufficient space for the movement of the driving gear 44. As mentioned above, the interruption of the driving force transmission between the driving gear 44 and the counting assembly 5 is preferably such that at least one of the driving gear 44 and the driven body 52 is in the position. Move in the above-mentioned moving direction, because the driven body 52 is a part of the counting assembly 5, and the counting assembly 5 also needs to interact with the detection components in the imaging device, so the way that the driving gear 44 moves in the moving direction is better, and The existence of the blank area can make the control device for controlling the movement of the driving gear 44 have a higher degree of design freedom.

As mentioned above, at least a part of the first forcing portion 14a is located in the vacant area, which not only enables the position adjustment of the first forcing portion 14a in the developing cartridge C according to the position of the external forcing force applying member, but also enables For the first forcing part 14a, a stronger reinforcing part is set; for example, when only the positions of the first forcing part 14a are slightly different between two types of developing cartridges, the existence of the vacant area can make the developing cartridges Also for example, when the forced thrust applied by the forced thrust applying part applied to a certain type of developer cartridge is relatively large, the designer can make full use of the vacant area to design a reinforcement for the first forced thrust part 14a, on the contrary, When the forcing force exerted by the forcing force applying member is small, the designer can also make full use of the vacant area to design a dispersing part for the first forcing part 14a that can disperse the forcing force.

The vacant area also simplifies the structure of the driving gear 44. No matter whether it is arranged coaxially with the powder feeding part 23, the driving gear 44 only needs to be provided with one stage, especially the above-mentioned fourth and fifth embodiments. As mentioned above, along the left and right directions, the size of the driving gear 44 and the counting assembly 5 can be reduced, thus, the size of the corresponding position of the developing cartridge C and the driving gear 44 is corresponding to the size of the corresponding position of the developing cartridge C and the counting assembly 5. can also be reduced.

For the embodiment that adopts the belt 15 or the gear rod 16 to transmit the driving force from the driving part to the driven part, similarly, between the driving force receiver 3/first gear 41/the third gear 43 as the driving part and the driven part A vacant area S20 is still formed between the drive gears 44 of the upper part. On the one hand, the conductive end 104 does not need to be provided with a gear for transmitting the driving force. On the other hand, the existence of the vacant area can also make the counting assembly 5 versatile. The movement of the driving gear 44 provides a space, so that the first forcing portion 14a has a higher degree of design freedom.

When the speed of rotation of the drive gear 44 is faster or slower than the expected speed of rotation, the counting assembly 5 can successfully complete the counting process by setting the speed regulating assembly in the developing cartridge, without the need for the drive gear 44 or dial The structure of the moving part 51 is changed, and at the same time, the structure of the speed regulating assembly can be adjusted according to the counting requirements of the moving part 51 in the target developing cartridge, so that the same moving part 51 can be used for various types of developing cartridges.

For the developer cartridge whose speed adjustment assembly is set as a delay device, the delay device is directly arranged on the rotating body 52, and there is no need to reserve space for setting the delay device in the developer cartridge C. The overall structure of the developer cartridge C It is simplified, and the delay device can also be integrally formed with the rotating body 52, so that the delay device can be installed along with the installation of the rotating body 52, without increasing the installation steps of the developing cartridge.

Specifically, the delay device in the present invention is to make the rotating body 52 stay for a predetermined time to realize the time delay by disengaging the rotating body 52 from the driving member 44, and then the rotating body 52 is combined with the driving member 44 again by the restarting device. It can be seen that during the entire counting process of the counting assembly 5, the average speed of the counting assembly 5 is reduced, and the time required for the counting piece to rotate a predetermined angle is lengthened, but the rotational speed of the drive gear 44 is not changed, and the rotating body 52 is rotating The rotation speed during the time has not been changed, which makes the structure of the driving gear 44 need not be changed, the counting assembly 5 only needs to increase the delay device which can be integrally formed with the rotating body 52, and the overall cost of the developing cartridge C can be controlled .

Those skilled in the art can understand that the counting assembly 5 described in each of the above embodiments can also be interchanged, for example, the counting assembly that does not move relative to the housing 1 along the rotation axis L5 involved in the first to third embodiments 5 is used in Embodiment 4-Example 13, or, the shrapnel 51b involved in Example 1 is used in Example 2-Example 13, or, the driven body E51 involved in Example 2 and Example 3 and The combined structure of the movable part E52 is used in the first embodiment, the tenth embodiment - the thirteenth embodiment, or the speed adjustment assembly described in the tenth embodiment - the thirteenth embodiment is applied in the first embodiment - the third embodiment, or The structure in which the driving force receiver 3 transmits the driving force to the driving gear 44 described in the fourth to ninth embodiments can also be applied to the first to third embodiments and the tenth to thirteenth embodiments.

In the above-mentioned embodiments, the counting assembly 5 and the gear set 44 can be arranged on the first outer surface 18, or on the side of the driving end cover 11 facing the housing 1; in the first embodiment to the third embodiment , the plane where the motion track of the counting assembly 5/pushing member 51/driven body 52 is located is perpendicular to the first direction, so that the counting assembly 5/pushing member 51/driven body 52 does not need to move relative to the housing along the rotation axis L5 The body 1 performs telescopic movement, the structures of the counting assembly 5 and the casing 1 can be simplified, and correspondingly, the installation of the counting assembly 5 and the assembly of the developing cartridge C become simple.
