Detailed Description
embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
First, as shown in fig. 1, the developing cartridge of the present invention comprises: a housing 1; an input gear 2 provided at one side end of the housing 1, which is engageable with a driving head in the image forming apparatus to receive a driving force of the image forming apparatus; a detected member 10, which is on the same side end as the input gear 2, can be detected by a detecting unit in the image forming apparatus.
As shown in fig. 2, the housing 1 includes a transmission gear 3 on the same side as the input gear 1, which can transmit the driving force to the detected component 10. The casing 1 is provided with a mounting column, which comprises a first mounting column 1a and a second mounting column 1b, the second mounting column 1b is coaxially arranged with the first mounting column 1a, and the maximum outer diameter of the second mounting column is smaller than that of the first mounting column. The detected member 10 includes a gear assembly 20, a detected portion 5, a first elastic member 6, and a side cover 7. When the assembly to be detected 10 is mounted, the gear assembly 20 is fitted to the first mounting column 1a, the detection body 5 is fitted to the second mounting column 1b, the first elastic member 6 is inserted into the first elastic member mounting hole 5a on the detection part 5, and finally the upper lid 7 is mounted. The first elastic member mounting hole 5a has a stopper face (not shown) for stopping the first elastic member 6 from coming off the first elastic member mounting hole 5a downward, so that the first elastic member 6 is compressed between the detected part 5 and the edge cover 7, and the detected part 5 is disposed at a biased position by the elastic force of the first elastic member 6. The side cover 7 is further provided with a limiting hole 7a, the detected part 5 is provided with a detected protrusion 5b, the detected protrusion 5b penetrates through the limiting hole 7a, and the limiting hole 7a limits the rotation of the detected protrusion 5b in the rotation direction so as to limit the rotation of the detected part 5 in the rotation direction.
As shown in fig. 3a and 3b, the gear assembly 20 comprises a top block 8, a second elastic member 9, a gear portion 4. The top block 8 is provided with a buckle 8a, an upright post 8b, a mounting main body 8c and a shifted part 8 d; the gear portion 4 is provided with a top block mounting hole 4a, a column accommodating hole 4b, and a column support surface 4 c. When the gear assembly 20 is mounted, the catch 8a and the mounting body 8c of the top block 8 are inserted through the dial block mounting hole 4a, and the second elastic member 9 is fitted into the catch 8a such that one end of the second elastic member 9 abuts against the gear portion 4 and the other end abuts against the catch 8a, thereby disposing the top block 8 at a biased position.
the process of inspecting the inspected assembly 10 is described below with reference to fig. 4-7. Referring to fig. 4, the column 8b is supported by the column support surface 4c, the top end of the top block 8 is provided with an arcuate push-out surface 8e, the detected part 5 is provided with a force receiving column 5c engageable with the push-out surface 8e, and the force receiving column 5c is provided with a side surface 5c1 and a bottom surface 5c 2. When the detected component 10 receives the driving force of the transmission gear 3, the gear part 4 starts to rotate, the top block 8 is driven to rotate together, the top block 8 gradually approaches the stress column 5c, and the top surface 8e is close to the lateral surface 5c1 and presses the lateral surface 5c 1. Referring to fig. 5, the top surface 8e presses the lateral surface 5c1 to move the top block 8 upward, and the top end of the top surface 8e contacts the bottom surface 5c2 of the force-bearing column 5c, at this time, the detected part 5 is in the extended position, and the detected protrusion 5b on the detected part 5 is lifted to the highest point and detected by the detection unit in the imaging device. Referring to fig. 6, a toggle block 5d is disposed on the detected portion 5 near the force-bearing column 5c, after the detected protrusion 5b is detected by the detecting unit in the imaging device, the top block 8 continues to rotate along with the gear portion 4, the toggle block 5d toggles the toggled portion 8d to rotate the top block 8, when the top block 8 rotates to a certain angle, the column 8b moves above the column receiving hole 4b in the gear portion 4, the elastic force of the second elastic member 9 biases the column 8b to move into the column receiving hole 4b, the top block 8 is also biased downward, the detected portion 5 is biased downward under the elastic force of the first elastic member 6 to be in the retracted position, and the detected protrusion 5b cannot be detected by the detecting unit in the imaging device. Alternatively, the toggle block 5d may be disposed on the side cover 7 or the housing 1, and the technical effect can be achieved as long as the toggled portion 8d can be toggled at the predetermined position. As shown in fig. 7, when the gear portion 4 receives the driving force of the transmission gear 3 to continue rotating, and the top block 8 rotates with the gear portion 4 to the force-receiving column 5 again, since the top block 8 has been biased downward by the second elastic member 9, the top end of the ejecting surface 8e will be located below the bottom surface 5c2 of the force-receiving column 5 without contacting the force-receiving column 5, and the gear 4 will not change the state of the detected portion 5 any more during the subsequent rotation.
According to the developing box provided by the invention, the arrangement of the gear with missing teeth in the detected component is cancelled, meanwhile, the detected component has a simple structure and low cost, and the technical problem that the manufacturing cost of the developing box is increased due to the adoption of the gear with missing teeth in the prior art is solved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
