[0021] Referring to Figs. 1 and 2, Fig. 1 is a schematic structural diagram of a processing cartridge provided by an embodiment of the present application, and Fig. 2 is a schematic structural diagram of the processing cartridge provided by an embodiment of the present application from another perspective. The embodiment of the present application discloses a processing cartridge 100, which is detachably installed on an image forming apparatus and includes a main body 1, a rotating member 2, and a detection assembly 3. The rotating member 2 is rotatably disposed on the main body 1 for performing image forming operations. The detection assembly 3 is disposed on the main body 1 for detecting whether the rotating member of the processing cartridge rotates normally.

[0022] In this embodiment, the rotating member 2 is a photosensitive drum or a developing roller. In other embodiments, the processing cartridge further includes a photosensitive drum and a developing roller, and the rotating member 2 can also be an element that can rotate with the rotation of the photosensitive drum or the developing roller. When the rotating member 2 is an element that rotates with the rotation of the photosensitive drum or the developing roller, the rotating member 2 further includes a drive gear, the detection portion 32 can be disposed on the drive gear, and the light-emitting portion and the light-receiving portion can be disposed at the drive end of the main body 1.

[0023] Specifically, the detection assembly 3 includes a detection portion 32 and a test component 31. The detection portion 32 is configured to be disposed on the rotating member 2 and can output a first detection signal. The test component 31 is configured to be disposed on the main body 1 and is configured such that when the detection portion 32 rotates to a predetermined position with the rotating member 2, the test component 31 can receive the first detection signal output by the detection portion 32, and the first detection signal can be used to determine whether the rotating member 2 meets expectations (for example, whether the rotation cycle and rotation speed of the rotating member meet preset values), thereby avoiding image abnormalities and machine damage caused by the stop or abnormal rotation of the rotating member 2.

[0024] Referring to Fig. 3, Fig. 3 is a partial structural diagram of the processing cartridge provided by an embodiment of the present application. The test component 31 includes a transmitting unit and a receiving unit. The transmitting unit is used to send a second detection signal, and the receiving unit is used to receive the first detection signal corresponding to the second detection signal based on the detection portion 32, so as to determine whether the rotating member 2 meets expectations through the first detection signal.

[0025] In this embodiment, the transmitting unit is a light-emitting portion 311, and the receiving unit is a light-receiving portion 312. The second detection signal and the first detection signal are signals of the same type, and the first detection signal is a signal obtained by enhancing or weakening the second detection signal. For example, the second detection signal is a first optical signal, and the first detection signal is a second optical signal obtained by enhancing or weakening the first optical signal. The detection portion 32 includes a reflecting portion 321, and the reflecting portion 321 is disposed on the outer surface of the rotating member 2. When the rotating member 2 rotates to a predetermined position, the reflecting portion 321 can reflect the first optical signal sent by the light-emitting portion 311 to form a second optical signal and emit it to the light-receiving portion 312, that is, enable the detection portion 32 to provide the second optical signal to the light-receiving portion 312 based on the first optical signal, so that the light-receiving portion 312 can determine whether the rotating member 2 works normally based on the cycle of the received second optical signal. Optionally, the detection portion 32 may include a signal conversion unit, which can process the aforementioned second detection signal to obtain the aforementioned first detection signal. Exemplarily, the signal conversion unit can process the aforementioned first optical signal to obtain the second optical signal. In addition, the test component 31 may also include the aforementioned signal conversion unit, that is, when the rotating member 2 rotates to a predetermined position, the reflecting portion 321 can reflect the second detection signal sent by the light-emitting portion 311 to the test component 31, and the signal conversion unit of the test component 31 can generate the first detection signal based on the received second detection signal. Exemplarily, the signal conversion unit can process the aforementioned first optical signal to obtain the second optical signal.

[0026] Further, the reflecting portion 321 can be attached to the rotating member 2, and the reflectivity of the reflecting portion 321 is higher or lower than that of the surface of the rotating member close to the reflecting portion 321. For example, the reflecting portion 321 is a reflective adhesive tape. By attaching the reflecting portion 321 to the rotating member 2, the reflecting portion 321 has a higher reflectivity compared to the surface of the rotating member 2, which facilitates the light-receiving portion 312 to determine whether the rotating member 2 works normally based on the cycle of the received second optical signal.

[0027] In addition, the reflecting portion 321 can also be a part of the surface of the rotating member 2, and the reflectivity of the reflecting portion 321 is higher or lower than that of the surface of the rotating member 2 close to the reflecting portion 321. For example, the reflecting portion 321 can be a layer of reflective material coated on the surface of the rotating member 2. In this embodiment, the reflecting portion is formed by directly coating a layer of reflective material on the surface of the rotating member 2, which has a simple process, reduces the number of components, and lowers the cost.

[0028] To improve the testing accuracy, the detection portion 32 further includes a light-absorbing portion 322, which is disposed along the circumferential direction of the rotating member 2 and adjacent to the reflecting portion 321. The light-absorbing portion 322 can be a layer of light-absorbing material coated on the surface of the rotating member 2. By disposing the light-absorbing material on the surface of the rotating member, it is possible to prevent other parts of the rotating member except the part coated with the reflective material from reflecting light to the light-receiving portion 312, reduce detection errors, and improve testing accuracy.

[0029] Specifically, the part of the outer surface of the rotating member 2 close to the reflecting portion 321 is a contrast portion, the reflectivity of the contrast portion is a, the reflectivity of the reflecting portion 321 is b, and the reflectivity of the light-absorbing portion 322 is c, then b > a > c.

[0030] Specifically, in the rotation direction of the rotating member 2, the light-absorbing portions 322 are disposed on both sides of the reflecting portion 321. Of course, in other embodiments, the reflecting portion 321 and the light-absorbing portion 322 can also be sequentially disposed along the forward or reverse rotation direction of the rotating member 2.

[0031] Optionally, the first detection signal and the second detection signal can also be signals of different types. For example, the first detection signal is a signal obtained by preset processing of the second detection signal. For example, the first detection signal is a third optical signal, the second detection signal is a second electrical signal, and the detection portion 32 is used to receive the second electrical signal, convert the second electrical signal into the third optical signal, and then provide the third optical signal to the receiving unit; or the first detection signal is a third electrical signal, the second detection signal is a fourth optical signal, and the detection portion 32 is used to receive the fourth optical signal, convert the fourth optical signal into the third electrical signal, and provide the third electrical signal to the receiving unit.

[0032] Continuing to refer to Fig. 3, the rotating member 2 includes a shaft member 22 and a cylinder 21. The shaft member 22 is rotatably disposed on the main body 1, and the cylinder 22 is sleeved on the shaft member 22, so that the cylinder 21 and the shaft member 22 are connected and can rotate coaxially. The reflecting portion 321 is configured to be attached to the outer circumferential surface of the shaft member, and the reflectivity of the surface of the reflecting portion 321 away from the shaft member 22 is higher or lower than that of other areas on the outer circumferential surface of the shaft member 22.

[0033] Optionally, the reflecting portion 321 is protrudingly disposed on the surface of the rotating member 2. Specifically, the reflecting portion 321 is configured to be installed on the shaft member 22, and when the reflecting portion 321 is installed on the shaft member 22, the reflecting portion 321 is protrudingly disposed on the shaft member 22; or the reflecting portion 321 is configured to be installed on the cylinder 21, and when the reflecting portion 321 is installed on the cylinder 21, the reflecting portion 321 is protrudingly disposed on the end surface of the cylinder 21.

[0034] During specific detection, light is emitted by the light-emitting portion 311. When the shaft member 22 rotates to a predetermined position, so that the detection portion 32 is on the path of the light emitted by the light-emitting portion 311, the first optical signal emitted by the light-emitting portion 311 can be reflected by the detection portion 32 to form a second optical signal and enter the light-receiving portion 312. The light-receiving portion 312 determines whether the rotating member 2 rotates normally based on the cycle of the received second optical signal, thereby avoiding image abnormalities and machine damage caused by the stop or abnormal rotation of the rotating member 2. Moreover, fewer components need to be matched in the printer, with low cost and simple structure.

[0035] In this embodiment, the light-emitting portion 311 and the light-receiving portion 312 are two independent components, and the light-receiving portion is a phototransistor. It can be understood that in other embodiments, the light-emitting portion and the light-receiving portion can also be integrated into one component.

[0036] Optionally, the detection assembly 3 further includes a chip 33, and the chip 33 is installed on the main body 1. The test component 31 is disposed on the chip 33. The chip 33 includes a substrate and terminals electrically connected to the substrate, and the terminals are used to contact and electrically connect with the terminals provided on the main body side of the image forming apparatus when the processing cartridge 100 is installed on the image forming apparatus. Further, the chip 33 may include a storage unit, where the storage unit is used to store attribute information representing the processing cartridge 100 and consumption information representing the developer contained in the processing cartridge 100. In this embodiment, the detection assembly 3 further includes a chip 33, the chip 33 is installed on the main body 1, the light-emitting portion 311 and the light-receiving portion 312 are respectively disposed on the chip 33, and the light-emitting portion 311 and the light-receiving portion 312 are respectively electrically connected to the chip 33, so that they can be electrically connected to the image forming apparatus through the terminals of the chip 33, and then directly transmit signals to the image forming apparatus without adding new components and wiring. It can be understood that in other embodiments, the light-emitting portion 311 and the light-receiving portion 312 can also be respectively disposed on the box body 1 or the main body of the image forming apparatus.

[0037] Optionally, the detection assembly 3 further includes a substrate and a Near-Field Communication (NFC) transmitting unit. The light-emitting portion, the light-receiving portion, and the NFC transmitting unit are respectively disposed on the substrate, and the light-receiving portion is electrically connected to the NFC transmitting unit, so that the rotation information of the rotating member measured by the detection assembly is input into the NFC transmitting unit. Meanwhile, a corresponding receiving device is provided on the main control chip of the image forming apparatus or the main body of the image forming apparatus, and then the information is transmitted back to the image forming apparatus through this radio frequency method, which is more convenient to install and more stable and safe in signal transmission.

[0038] To improve the accuracy of detecting the rotating member 2, the test component 31 further includes a light-blocking component 313. The light-blocking component 313 is disposed on the main body 1 and between the light-emitting portion 311 and the light-receiving portion 312, and the light-blocking component 313 protrudes from the light-emitting portion 311 and the light-receiving portion 312 in the direction toward the rotating member 2, so that the light-blocking component 313 can prevent the first optical signal emitted by the light-emitting portion 311 from directly transmitting to the light-receiving portion 312 and affecting the judgment of whether the rotating member 2 rotates normally.

[0039] Specifically, the light-blocking component 313 is disposed on the main body 1, and the chip 33 is provided with a notch. When the chip 3 is installed on the main body 1, the notch of the chip 33 will cooperate with the light-blocking component 313 for limiting, so as to limit the chip 33 and prevent the detection result from being affected by the processing tolerance of the chip 33.

[0040] Optionally, the distance between the light-blocking component 313 and the rotating member 2 is greater than or equal to 1mm, preferably, the distance between the light-blocking component 313 and the rotating member is 1.3mm, so as to avoid interference between the light-blocking component and the rotating member.

[0041] Optionally, the detection assembly 3 further includes a sleeve 34, the sleeve 34 is sleeved on the shaft member 22, and the detection portion 32 is disposed on the sleeve 34. Specifically, the detection assembly 3 further includes a limiting member 35, the limiting member 35 is sleeved on the shaft member 22 for limiting the sleeve 34, referring to Fig. 4(a) and Fig. 4(b).

[0042] The detection portion 32 is installed on the sleeve 34, for example, the installation method can be detachable or attached; or the detection portion 32 is a depression, protrusion, through hole, or reflective layer on the sleeve 34.

[0043] During detection, the first optical signal is emitted by the light-emitting portion 311. When the rotating member 2 rotates to a predetermined position, so that the reflecting portion 321 is on the path of the first optical signal emitted by the light-emitting portion 311, the first optical signal emitted by the light-emitting portion 311 will be incident on the reflecting portion 321, and the reflecting portion 321 will convert the first optical signal into the second optical signal and transmit it to the phototransistor. The phototransistor will conduct when there is sufficient light, pulling down the collector potential, and will not conduct when there is no light, pulling up the potential through a pull-up resistor. Thus, the rotation cycle of the photosensitive drum can be determined according to the characteristics of the phototransistor, and then it can be determined whether the photosensitive drum rotates normally.

[0044] Optionally, the detection portion 32 further includes a photoelectric conversion unit and an electro-optical conversion unit, both of which are disposed on the rotating member. The photoelectric conversion unit is used to receive the first optical signal and generate a first electrical signal from the first optical signal, and the electro-optical conversion unit is used to receive the first electrical signal and generate a second optical signal from the first electrical signal, which is then transmitted to the light-receiving portion, so as to enhance or weaken the optical signal through the photoelectric conversion unit and the electro-optical conversion unit.

[0045] Optionally, the detection portion can output a first detection signal; when the rotating member rotates to a predetermined position, the test component can receive the first detection signal output by the detection portion. For example, the detection portion is a light source, and the test component is a light sensor; or the detection portion is a magnetic member, and the test component is a Hall sensor or a proximity switch; or the detection portion is an NFC tag for sending information to the test component, and the test component is an NFC receiver; or the detection portion is a sound source, and the test component is a sound sensor; or the detection portion is an inductance coil, and the test component is an inductive component. In the above methods, the detection portion can directly send a signal and the test component can receive it. It can be understood that when the detection portion rotates to a predetermined position with the rotating member, the test component can receive the signal sent by the detection portion to detect whether the rotation of the rotating member meets expectations.

[0046] Optionally, referring to Fig. 8(a), Fig. 8(b), and Fig. 8(c), the rotating member 2 includes a shaft member 22 and a cylinder 21, and the cylinder 21 is rotatably sleeved on the shaft member 22, so that the cylinder 21 can rotate relative to the shaft member 22. That is, during operation, the shaft member does not rotate and only plays a supporting role, while the cylinder can rotate relative to the shaft member.

[0047] The detection portion 32 is configured to be disposed on the inner side of the cylinder 21. For example, the detection portion can be disposed on the inner surface of the cylinder, and the test component 31 is configured to be disposed on the shaft member 22.

[0048] During detection, when the cylinder 21 rotates to a predetermined position, so that the reflecting portion 321 is on the optical path of the optical signal emitted by the light-emitting portion 311, the optical signal emitted by the light-emitting portion 311 will be incident on the reflecting portion 321, and the reflecting portion 321 will reflect the optical signal emitted by the light-emitting portion to the light-receiving portion 312, so that the light-receiving portion 312 can determine whether the rotating member rotates normally based on the cycle of the received optical signal.

[0049] Specifically, the detection assembly 3 is an optical detection assembly, which detects whether the rotating member rotates normally by means of optical detection. The detection portion includes a reflecting portion, and outputs an optical signal, that is, a detection signal, through the reflection of the reflecting portion. Of course, in some embodiments, the detection portion may also include a refracting portion, and the first optical signal is refracted by the refracting portion to form a second optical signal and received by the light-receiving portion; or the detection portion is a magnetic member, the first detection signal is an electromagnetic wave signal, and the test component is a Hall sensor or a proximity switch; or the detection portion is a sound source, the first detection signal is an acoustic wave signal, and the test component is a sound sensor; or the detection portion is an NFC tag for sending information to the test component, and the test component is an NFC receiver; or the detection portion is an inductance coil, and the test component is an inductive component; or the detection portion is a light source, and the test component is a light sensor.Embodiment 2

[0063] Optionally, referring to Fig. 5, the reflecting portion 321 is a groove opened on the rotating member 2, so that the first optical signal emitted by the light-emitting portion 311 is incident into the groove and reflected by the groove to form a second optical signal to be received by the light-receiving portion 312.

[0064] Specifically, the groove is disposed on the end surface of the shaft member 22, and both the light-emitting portion 311 and the light-receiving portion 312 are located on the same side of the rotating member 2. When the rotating member 2 rotates to a predetermined position, the projections of the light-emitting portion 311 and the light-receiving portion 312 on the rotating member 2 are respectively located on both sides of the detection portion 32. In other embodiments, the groove can also be disposed on the end surface of the cylinder.

[0065] During detection, the first optical signal is emitted by the light-emitting portion 311. When the rotating member 2 rotates to a predetermined position, so that the projections of the light-emitting portion 311 and the light-receiving portion 312 are located on both sides of the groove, the first optical signal emitted by the light-emitting portion 311 will be reflected by the groove to form a second optical signal and incident into the light-receiving portion 312, so that the light-receiving portion 312 can determine whether the rotating member rotates normally based on the cycle of the received second optical signal.

[0066] Optionally, referring to Fig. 6 and Fig. 7, the reflecting portion 321 is a through hole opened on the rotating member 2. When the rotating member 2 rotates to a predetermined position, the light emitted by the light-emitting portion 311 can pass through the through hole and be received by the light-receiving portion 312, and the second optical signal is at least part of the first optical signal. Specifically, the through hole is disposed on the shaft member 22, the light-emitting portion 311 and the light-receiving portion 312 are respectively disposed on both sides of the shaft member 22, and the positions of the light-emitting portion 311, the light-receiving portion 312, and the through hole are correspondingly set.

When the shaft member 22 rotates to a predetermined position, so that the light-emitting portion 311, the through hole, and the light-receiving portion 312 are in the same straight line, the optical signal emitted by the light-emitting portion 311 will pass through the through hole and be incident on the light-receiving portion, so that the rotation cycle of the rotating member can be determined according to the cycle of the optical signal received by the light-receiving portion, and then it can be determined whether the rotating member rotates normally. In other embodiments, the extending direction of the through hole may not be straight, and the light emitted by the light-emitting portion 311 may also be refracted or reflected in the through hole before being received by the light-receiving portion. For example, the through hole includes a first hole section and a second hole section that are connected, and the first hole section and the second hole section are arranged at an angle; or a light-transmitting member is disposed in the through hole, and the light is refracted by the light-transmitting member in the through hole and then received by the light-receiving portion.

[0068] Optionally, the detection portion is a depression or protrusion disposed on the outer circumferential surface of the rotating member, and the test component is an inductive component configured to be disposed opposite to the detection portion. Specifically, the cross-section of the rotating member at the position where the detection portion is provided is a D-shaped surface. When the rotating member rotates to a predetermined position, the test component can obtain a signal based on the shape change of the outer circumferential surface of the rotating member.
