The detected piece 220 comprises a push rod penetrating through the detection outlet 131 and a force receiving part 221 arranged at the end part of the push rod, the force receiving part 221 is arranged at a position close to the axis of the push seat 210 and is positioned on the movement path of the push seat 211, the push seat 210 pushes the detected piece 220 to move on the detection outlet 131 through the push seat 211, the force receiving area of the detected piece 220 can be increased, the force receiving fault tolerance of the detected piece 220 is improved, and accurate push between the push seat 210 and the detected piece 220 is realized.
Specifically, referring to fig. 2 to 5, the detecting outlet 131 is provided with an elastic reset member 400, and the elastic reset member 400 is respectively connected with the end cover 120 and the detected member 220, so that the detected member 220 has movement potential energy retracted from the detecting outlet 131, and the detected member 220 is reset.

Referring to fig. 3 to 5, the developing cartridge of the present embodiment 1 operates as follows: after the driving force receiving assembly 300 receives the driving force, the driving force is transmitted to the pushing seat 210, so as to drive the pushing seat 210 to rotate along the X direction, the pushing portion 211 of the pushing seat 210 pushes the detected piece 220 to gradually extend out of the detection extending opening 131 through the force bearing portion 221 in the rotating process, the detection signal is transmitted to the external detection mechanism, and after the pushing portion 211 on the pushing seat 210 leaves the detection extending opening 131, the elastic reset piece 400 pushes the detected piece 220 to reset, and the detected piece 220 is retracted back into the detection extending opening 131.
Example 2
Referring to fig. 6 to 14, the end cap 120 is provided with a ring guide 140 and a blocking portion 150, the ring guide 140 is disposed along a circumferential direction of the push base 210, a detection protrusion 131 formed on the end cap 120 between the ring guide 140 and the blocking portion 150, the detected member 220 is connected to the push base 210, the detected member 220 abuts against the ring guide 140 during rotation of the push base 210, and the ring guide 140 guides the detected member 220. After receiving the driving force, the pushing base 210 pushes the detected member 220 to move, and the detected member 220 moves along the ring guide 140 and finally protrudes into the detection protrusion hole 131.
Specifically, the pushing base 210 is provided with a force application portion 212, the detected member 220 is folded and connected to the force application portion 212, and the force application portion 212 pushes the detected member 220 to move along the loop guide portion 140, gradually passes through the detection outlet 131 and extends out of the detection outlet 131. The pushing base 210 pushes the inspected piece 220 to move along the ring guide 140 and causes the inspected piece 220 to protrude from the inspection protrusion hole 131. The force application part 212 is connected to the force application part 212 of the push seat 210 in a turnover way, so that the detected piece 220 is retracted into the detection extending hole 131 along with the continuous movement of the push seat 210, the automatic retraction function of the detected piece 220 is realized, the design is ingenious, the detected piece is retracted along with the continuous movement of the push seat 210 under the condition of not using a reset piece, and the detected piece is separated from the detection mechanism.
Referring to fig. 9 to 12, the developing cartridge of the present embodiment 2 operates as follows: the driving force is transmitted to the pushing seat 210 through the driving force receiving assembly 300 to drive the pushing seat 210 to rotate, the pushing seat 210 rotates around the rotating shaft of the pushing seat along the Y direction, the detected piece 220 is pushed to rotate through the force application part 212, the detected piece 220 is guided to the detection extending opening 131 through the annular guide part 140 and gradually extends to the outer side of the detection extending opening 131, a detection signal is transmitted to the detection mechanism, until the force application part 212 on the pushing seat 210 reaches the detection extending opening 131, the detected piece 220 is in the maximum extending position, the pushing seat 210 continues to rotate after that, the detected piece 220 is pushed back and folded by the blocking part 150 due to the folding connection of the detected piece 220 on the force application part 212, the gap formed between the blocked part 150 and the force application part 212 limits the detected piece 220 to gradually approach the force application part 212, the detected piece 220 starts to retract from the detection extending opening 131, and is folded to the outer side of the force application part 212 under the action of the blocking part 150.
In the above-mentioned one extending process of the detected member 220, when the detected member 220 needs to perform two or more extending processes on the detecting extending port 131, the detected member 220 can have a reset function, continue to rotate along the Y direction, and a neutral gear period is provided between the blocking portion 150 and the ring guiding portion 140, and when the folded detected member 220 is separated from the blocking portion 150, the detected member 220 is reset to an initial position in the neutral gear period, and can continue to extend into the detecting extending port 131 along the ring guiding portion 140 in the next rotating process, so as to repeat. The detected piece 220 is preferably an arc structure protruding outwards away from the pushing seat 210, and an arc of the arc structure is similar to or coincides with an arc side wall of the ring guide 140, and can be abutted against the arc side wall of the ring guide 140, so that the action consistency of the detected piece 220 can be improved, and smooth action of the detected piece 220 is ensured.
Further, referring to fig. 7, an end of the ring guide 140, which is close to the detection outlet 131, has a detection guiding surface 141, and the detection guiding surface 141 gradually gets away from the rotation axis of the push seat 210 in the process of approaching to the detection outlet 131, and is in an outward expansion structure. The pushing base 210 rotates in the Y direction, and when the extended end of the detected piece 220 passes the detection guide surface 141, the detected piece 220 gradually deviates from the original circumferential movement, and finally can be extended on the detection extension port 131. It should be noted that, the detected piece 220 may be directly integrally formed on the force application portion 212, where the detected piece 220 has an anti-deformation capability, when the detected piece 220 abuts against the ring guide portion 140, there is a tendency of expanding and resetting, and when the pushing seat 210 rotates, the detected piece 220 moves along the inner sidewall of the ring guide portion 140 all the time, and can extend to the detection extending port 131. In combination with the above multi-time expansion structure, an entry guide surface may be provided at the entry end of the ring guide 140, so that the multi-time expansion process can be continuously implemented.
Further, one end of the blocking portion 150 near the detection outlet 131 has a turnover guiding surface 151, and the turnover guiding surface 151 gradually approaches the rotation axis of the pushing seat 210 in the process of being far away from the detection outlet 131, and forms a trumpet-shaped structure on the inner side of the detection outlet 131 with the detection guiding surface 141. The pushing base 210 rotates along the Y direction, the force application part 212 continues to move through the detection outlet 131, the detected piece 220 gradually approaches the outer side wall of the force application part 212 under the action of the turnover guide surface 151, and the detected piece retracts from the detection outlet 131 during turnover. The turning guide surface 151 plays a role in guiding the turning process of the turning guide surface 151, corresponds to the expansion speed of the detected piece 220 on the detection outlet 131, and avoids the damage to the detected piece 220 caused by the fact that the detected piece 220 is bent at two side edges of the detection outlet 131 due to the fact that the detected piece 220 is turned over too fast on the blocking portion 150.
Further, the end cover 120 has a through hole 121 coaxially disposed with the pushing seat 210, the pushing seat 210 is disposed in the through hole 121, and the through hole 121 can be used for observing the movement of the detected member 220 and protecting the pushing seat 210. The loop guide portion 140 and the blocking portion 150 are disposed on the edge of the hole of the measured through hole 121, and the force application portion 212, after passing through the blocking portion 150, makes the measured member 220 enter the reset active area, i.e. in the above mentioned neutral position, so as to conveniently reset the measured member 220.
In another embodiment of the present invention, referring to fig. 13 and 14, in order to implement a single driving of the push base 210 by the driving force receiving assembly 300, the push base 210 has a connection toothed ring 213, the driving force receiving assembly 300 includes a transmission gear 310 meshed with the connection toothed ring 213, and the connection toothed ring 213 has a tooth missing portion 2131 capable of being disengaged from the transmission gear 310. The connection ring 213 is circumferentially arranged along the rotation axis of the push holder 210, and the connection ring 213 has a continuous tooth structure, but does not have a tooth structure capable of meshing with the transmission gear 310 at the missing tooth portion 2131. When the transmission gear 310 is meshed with the connection toothed ring 213, the pushing base 210 is driven to rotate by the gear tooth structure until the connection toothed ring 213 is not meshed with the transmission gear 310 after reaching the toothless portion 2131, and the driving force on the driving force receiving assembly 300 cannot be transmitted from the transmission gear 310 to the pushing base 210.
Specifically, the main casing 110 has a limiting portion 160, the push seat 210 has a limiting blocking piece 214, and when the connecting gear ring 213 is separated from the transmission gear 310, the limiting blocking piece 214 abuts against the limiting portion 160, so as to avoid the connecting gear ring 213 from continuing to rotate under the unexpected conditions of gravity, impact, vibration, etc., and touching and meshing with the transmission gear 310 again. In the present embodiment, the limiting block 214 is disposed on the tooth missing portion 2131 of the connecting gear ring 213, and of course, the setting positions of the limiting block 214 and the limiting portion 160 can be determined according to the final disengaging position of the pushing base 210 on the driving force receiving assembly 300.
Further, the driving force receiving assembly 300 is configured to receive the driving force input from the driving mechanism and transmit the driving force to the respective components of the developing cartridge (including the detected assembly 200). In this embodiment, the driving force receiving assembly 300 is composed of a gear set, and transmits power to each component, and may receive driving force by means of gear transmission, or may receive driving force on the driving mechanism by means of belt transmission or other transmission means.
In other embodiments, the developer cartridge may also include other structures such as developer receiving chambers, agitator frames, etc., not described herein.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
