Abstract
Description
Technical Field
[0001] This invention relates to the field of electrophotographic imaging equipment, and in particular to a developing cartridge. Background Technology
[0002] As is well known, an electrophotographic imaging device includes a main component, a photosensitive drum disposed in the main component, and a developing cartridge that supplies developer to the photosensitive drum.
[0003] This imaging device includes a detection unit for determining information about the developing cartridge installed in the imaging device. For example, the detection unit is used to determine whether a newly installed developing cartridge is a new product, or to determine the size and capacity information of the developing cartridge.
[0004] In this type of imaging equipment, the developing cartridge can be detachably mounted on the main component of the imaging equipment. The main component is equipped with a transmission mechanism and a light sensor. This developing cartridge rotatably supports a device under test, which has a protrusion (the component under test) that can touch and push the transmission mechanism. When the developing cartridge is mounted on the main component, the device under test is driven to rotate, and the protrusion causes the transmission mechanism to oscillate. The light sensor detects the oscillation of the transmission mechanism, and the imaging equipment uses the light sensor's detection results to determine information about the developing cartridge.
[0005] Similarly, besides using the detection results of a light sensor to determine the information of the developing cartridge, there is also a capacitance detection method. This involves the protrusion touching the oscillation of the transmission mechanism, causing a change in capacitance, which is then used to determine the information of the developing cartridge. Another method is to determine the information of the developing cartridge by changing the voltage or current in the circuit through the opening and closing of a switch. Specifically, this can be achieved by the protrusion touching the oscillation of the transmission mechanism to open or close the switch.
[0006] A developing cartridge has a driving force receiving unit at its first end along its length, and a detection component at its second end opposite to the first end. A rotating shaft is provided between the first and second ends, capable of receiving and rotating a rotational driving force to transmit the rotational driving force from the first end to the second end of the developing cartridge, thereby driving the detection component at the second end. The developing cartridge also contains a rotatable stirring component for stirring the developer. The rotating shaft of this stirring component transmits the rotational driving force for driving the detection component, which means the rotating shaft must simultaneously bear the forces of stirring the developer and driving the detection component, posing a risk of deformation or even breakage. Summary of the Invention

[0079] An embodiment discloses a developing cartridge for an imaging device, the imaging device including a main component and a detection unit 100 disposed in the main component (see...). Figure 1 The main assembly includes a photosensitive drum and a drive transmission component. The detection unit 100 and the drive transmission component are located on different sides of the main assembly. The detection unit 100 is located on one side of the main assembly and is used to detect information from the developing cartridge installed in the main assembly. It is equipped with a transmission mechanism 200 (see...). Figure 1 The transmission mechanism 200 can swing in response to the force of the developing cartridge, and the imaging device uses the swing of the transmission mechanism 200 to block the sensor 300 (see...). Figure 1 The information of the developing cartridge is determined by the condition of the developing cartridge. A drive transmission component is located on the other side of the main assembly and is used to transmit driving force to the developing cartridge. The structure and detection principle of the imaging device can be found in the printer structure and detection principle disclosed in Chinese Patent Publication No. CN105759586A; related existing technologies will not be elaborated here.
[0080] The structure of the developing cartridge will be described in detail below with reference to the embodiments.
[0081] Example 1
[0082] like Figures 1 to 3 As shown, the developing cartridge 10a is detachably installed in the main component of the imaging device described above, and its specific structure includes a cartridge body 1a and a driving force receiving unit 2a.
[0083] The housing 1a is generally rectangular in shape, with a first sidewall 11a and a second sidewall 12a along its length L. It typically houses a powder hopper 13a for containing developer, a developing roller 14a, a powder delivery roller, and a stirring member 15a. The developing roller 14a is positioned at the front of the developing housing 10a in the direction it is mounted to the imaging equipment. It is exposed from the front of the housing 1a and faces the photosensitive drum when mounted to the imaging equipment, enabling the development process. The powder delivery roller faces the developing roller 14a and delivers developer to it. The stirring member 15a agitates the developer contained in the powder hopper 13a.
[0084] A driving force receiving unit 2a is disposed on the first side (or the first end of the developing cartridge 10a) along the length L of the cartridge 1a, and is used to receive driving force from the driving transmission component of the imaging device and to transmit rotational driving force to rotating components such as the developing roller 14a. The driving force receiving unit 2a disclosed in this invention may include a connecting member 21a, or may include one or more of the following: a developing roller gear 22a, a powder feeding roller gear 23a, a stirring component gear, and an idler wheel 24a. In this embodiment, the driving force receiving unit 2a includes a connecting member 21a, a developing roller gear 22a, a powder feeding roller gear 23a, and an idler wheel 24a.
[0085] The connecting member 21a is rotatably supported on the first side wall 11a of the housing 1a, and its axis of rotation extends along the length L of the developing cartridge 10a, parallel to the axis of rotation of the developing roller 14a. The connecting member 21a is provided with a drive force receiving part 211a and a first gear part 212a. The drive force receiving part 211a is connected to the drive transmission component of the imaging device and receives the drive force. The first gear part 212a can mesh with the developing roller gear 22a, the powder feeding roller gear 23a, and the idler gear 24a to transmit rotational drive force to these components. The developing roller gear 22a and the powder feeding roller gear 23a are respectively located at the ends of the developing roller 14a and the powder feeding roller to drive them to rotate. A stirring component gear is located at the end of the stirring component 15a and meshes with the idler gear 24a to drive the stirring component 15a to rotate.
[0086] The developing cartridge 10a has a first end cap 101a and a second end cap 102a at its two ends. The first end cap 101a is located outside the first side wall 11a to protect the driving force receiving unit 2a. The second end cap 102a is located outside the second side wall 12a, and the detected component 6a (which will be described in detail later) can be exposed from the second end cap 102a.
[0087] like Figures 4 to 6 As shown, in this embodiment, the developing cartridge 10a is further provided with a driving component 3a, a transmission component 4a, an elastic component 5a, and a detection component 6a.
[0088] For ease of description, the direction parallel to the installation direction P of the developing cartridge 10a is taken as the front-back direction of the developing cartridge 10a, the position of the developing roller 14a is taken as the front side of the developing cartridge 10a, and the side opposite to the front side is taken as the rear side; the length direction L of the cartridge body 1a is taken as the left-right direction of the developing cartridge 10a, the first side wall 11a is located on the left side of the developing cartridge 10a, and the second side wall 12a is located on the right side of the developing cartridge 10a; the direction perpendicular to the front-back direction and the left-right direction is taken as the up-down direction T. When the developing cartridge is installed in the imaging device, the upper side of the developing cartridge is taken as the top, and the lower side is taken as the bottom.
[0089] The driving component 3a can receive a driving force and move accordingly. This driving force can be received directly from the driving force receiving unit 2a or indirectly. The driving force can be a rotational driving force or a pushing force, and the corresponding movement of the driving component 3a can be rotation or sliding.
[0090] Preferably, the drive member is rotatably disposed. The drive member may include a main body, a second gear capable of meshing with the drive force receiving unit, and an actuating part capable of driving the transmission member. The actuating part may extend along the rotation axis of the drive member or in a radial direction.
[0091] In this embodiment, the driving component is a cam component 3a, and the actuating part is a cam portion. Specifically, the cam component 3a includes a cylindrical main body 31a, on which a second gear portion 32a capable of meshing with the driving force receiving unit 2a and a cam portion capable of driving the transmission member 4a are provided. In this invention, the cam portion may be or include a protrusion extending along the rotation axis direction or radial direction of the cam component.
[0092] In this embodiment, the rotation axis of the cam component 3a is parallel to the length direction L of the box 1a. There are two cam parts, namely the first cam part 33a and the second cam part 34a. The first cam part 33a and the second cam part 34a have basically the same shape and structure. The first cam part 33a will be used as an example for the following description.
[0093] The first cam portion 33a protrudes from the end face of the main body portion 31a along the length direction L of the housing 1a. Specifically, the first cam portion 33a protrudes away from the first side wall 11a along the length direction L of the housing 1a. Its side is also provided with a first guide surface 35a and a second guide surface 36a. In the rotational direction of the cam member 3a, the first guide surface 35a is located upstream of the second guide surface 36a. The main body portion 31a is cylindrical, and the two cam portions are arranged at a predetermined distance in the circumferential direction of the main body portion 31a.
[0094] In this embodiment, the cam component 3a is disposed at the end of the stirring component 15a, and it can act as a gear of the stirring component 15a. Its second gear part 32a meshes with the idler wheel 24a of the driving force receiving unit 2a to receive the rotational driving force, which can drive the stirring component 15a to rotate.
[0095] Alternatively, the cam component 3a can also be set at the end of the developing roller 14a or the powder feeding roller, or it can be set independently on the cartridge 1a.
[0096] The transmission member 4a can receive the force from the driving member 3a, causing at least a portion of the transmission member 4a to move along the length direction L of the housing 1a. The transmission member 4a is used to drive the detected member 6a. The driving method can be that the detected member 6a is fixedly connected to the transmission member 4a or integrally formed with the transmission member 4a and moves with the transmission member 4a, or the detected member 6a is movably connected to the transmission member 4a, or the driving can be achieved by the transmission member 4a touching the detected member 6a, etc.
[0097] The transmission member 4a is movable between a first position where it is not pushed by the cam portion and a second position where it is pushed by the cam portion. The transmission member 4a is provided with a force-receiving part 41a that receives the force of the cam portion of the cam member 3a. This force-receiving part 41a can also be pushed by the cam portion, so that the transmission member 4a can move between the first position and the second position.
[0098] In this embodiment, the transmission member 4a is a sliding member, which includes a force-receiving part 41a and a rod part 42a. The rod part 42a extends in the longitudinal direction L of the box body 1a, and at least a portion of it is located between the first side wall 11a and the second side wall 12a. The rod part 42a is slidably disposed on the box body 1a, and the cam part can push the force-receiving part 41a to slide in the longitudinal direction L of the box body 1a.
[0099] The box body 1a is provided with a sliding groove portion 16a, which serves as an example of a transmission component receiving groove. At least a portion of the transmission component 4a is installed in the sliding groove portion 16a so that the transmission component 4a can slide in the length direction L of the box body 1a. The number of sliding groove portions 16a can be one or more, and the way to achieve the sliding of the transmission component 4a is not limited to the sliding groove method. It can also be that a storage portion for storing the transmission component 4a is provided, etc.
[0100] The elastic element 5a is used to apply a force to the transmission element 4a so that the transmission element 4a can move from the second position to the first position.
[0101] Specifically, the elastic element 5a is a compression spring, one end of which abuts against the elastic element support portion 51a on the housing 1a, and the other end abuts against a portion of the transmission element 4a. As the transmission element 4a moves from the first position to the second position, it compresses the elastic element 5a to the left. More specifically, the transmission element 4a has a receiving portion in which the elastic element 5a is received.
[0102] Alternatively, such an elastic element 5a can also be a tension spring, a torsion spring, or an elastic sponge, etc.
[0103] The component 6a to be detected is disposed at the second end of the developing cartridge 10a and can be driven by the transmission component 4a. This driving method can be direct driving or indirect driving. For example, the component 6a to be detected and the transmission component 4a are integrally formed, connected in a linkage relationship, or driven at a preset distance, all of which fall within the scope of the driving method disclosed in this invention.
[0104] In this embodiment, the component 6a to be detected is oscillatingly disposed at the second end of the housing 1a and can be driven by the transmission member 4a. Specifically, the component 6a to be detected is provided with a force receiving part 61a, a connecting part 62a and a detection part 63a. The connecting part 62a is oscillatingly connected to a pivot on the housing 1a or the second end cover 102a and has an oscillation center.
[0105] The force receiving part 61a extends from the connecting part 62a and is oscillatingly connected to one end of the transmission member 4a (for example, forming a linkage mechanism). Specifically, the end of the rod part 42a is provided with a circular hole and is movably connected to the shaft part (force receiving part 61a) of the detected member 6a. When the transmission member 4a moves along the length direction L of the housing 1a, it can drive the detected member 6a to oscillate. The detected part 63a extends in a different direction than the force receiving part 61a, so that it can trigger the detection unit 100 of the imaging device when the detected member 6a oscillates.
[0106] In this embodiment, the developing cartridge 10a further includes a clutch mechanism 7a, which is used to cut off the transmission of driving force to the transmission member 4a. Specifically, the clutch mechanism 7a includes a notch 71a provided on the cam member 3a. The notch 71a is located radially outside the main body 31a of the cam member 3a. The force-receiving part 41a of the transmission member 4a can fall into the notch 71a. At this time, the force-receiving part 41a is disengaged from the path taken by the rotation process of the cam member, and thus no longer receives the force from the cam member, thereby achieving the cutting off of the driving force.
[0107] Next, combine Figures 4 to 7 This section describes the process by which the developing cartridge 10a is detected by the detection unit 100 of the imaging device.
[0108] like Figure 6 As shown, in this embodiment, when the developing cartridge 10a is in an unused state, the transmission member 4a is in the second position (initial position), the elastic member 5a is in a compressed state, and the detected member 6a is in a state where the detection unit 100 is not triggered.
[0109] The user installs the developing cartridge 10a into the imaging device, and the connecting member 21a connects to the drive transmission component of the imaging device. When the imaging device starts operating, the idler wheel 24a receives the driving force from the connecting member 21a and drives the cam component 3a to rotate. As the cam component 3a rotates, the force-bearing part 41a moves from the top of the first cam portion 33a along the first guide surface 35a to the root of the first cam portion 33a under the push of the first cam portion 33a. At this time, under the elastic restoring force of the elastic member 5a, the transmission member 4a slides to the right, and the detected component 6a rotates under the drive of the transmission member 4a and touches the detection unit 100 of the imaging device.
[0110] As the cam member 3a rotates, the force-bearing part 41a of the transmission member 4a moves along the second guide surface 36a of the second cam member 34a from the root of the cam member to the top of the second cam member 34a under the push of the second cam member 34a. At this time, the transmission member 4a slides to the left and drives the detected member 6a to rotate, and the detected member 6a disengages from the detection unit 100. As the force-bearing part 41a moves along the first guide surface 35a from the top of the second cam member 34a to the root of the second cam member 34a, under the action of the elastic restoring force of the elastic member 5a, the transmission member 4a slides to the right and drives the detected member 6a to rotate, and the detected member 6a touches the detection unit 100 a second time. As the cam member 3a rotates, the force-bearing part 41a moves along the end face of the cam member 3a and finally falls into the notch 71a (e.g., Figure 7 As shown, the cam component 3a continues to rotate, while the transmission component 4a is not pushed, and the test is completed.
[0111] The number of cam sections can be set according to the number of times the detection unit 100 needs to be turned. For example, one cam section can be set when one turn is required, and multiple cam sections can be set when multiple turns are required. The structures of different cam sections can also be different. They can be set according to the force and amplitude of the driving transmission component, so as to distinguish different models or different capacities of developing cartridges.
[0112] In the developing cartridge 10a having the above structure, at least a portion of the transmission member 4a moves along the length direction L of the cartridge body 1a. (Reference) Figure 7 It can be seen that the distance that the transmission component 4a moves along the length direction L of the box 1a is d1. This distance d1 is the same as or greater than the protrusion of the cam part (i.e., the distance from the root of the cam part to the top of the cam part).
[0113] The developing cartridge 10a with the above structure eliminates the need to transmit the force driving the tested component 6a through the rotation shaft of the stirring member 15a, thus eliminating the risk of deformation or even breakage of the rotation shaft of the stirring member 15a. By using a sliding mechanism to transmit the driving force from the first end of the developing cartridge 10a to the second end, the problem of driving force transmission delay caused by deformation of the rotation shaft of the stirring member 15a is solved, improving detection accuracy. At the same time, the torque required by the developing cartridge 10a is also greatly reduced, making its operation more stable.
[0114] In some implementation examples, the component being detected is integrally formed with the transmission component 4a. The component being detected is located at the end of the transmission component 4a and moves with the movement of the transmission component 4a, thereby triggering the detection unit 100 of the imaging device.
[0115] In some implementation examples, the component 6a being tested is configured as a slider that slides by the pushing force of the transmission component 4a.
[0116] In some implementation examples, the elastic element 5a is not connected to the transmission element 4a, but is instead connected to the detected element 6a, and the detected element 6a pushes the transmission element 4a to move from the second position to the first position.
[0117] In some implementation examples, the component being tested does not come into contact with the transmission component, that is, the two can be separated by a preset distance, as long as the transmission component 4a can drive the component being tested 6a when it moves.
[0118] In some implementation examples, the clutch mechanism can also be located between the drive force receiving unit 2a and the cam member 3a, thereby indirectly cutting off the transmission of drive force to the transmission member 4a by disconnecting the drive force transmission between the drive force receiving unit 2a and the cam member 3a.
[0119] In some implementations, the driving member 3a is a rack structure that meshes with the driving force receiving unit 2a. The rack structure receives the driving force and moves, and is able to push the transmission member 4a to move in the longitudinal direction of the developing cartridge.
[0120] In some implementation examples, the initial position of the transmission member 4a is the first position, and when the transmission member 4a moves from the first position to the second position, it drives the detected component 6a to touch the detection unit of the imaging device.
[0121] In some implementation examples, the component 6a being tested may or may not be in contact with the transmission mechanism 200 of the detection unit 100 in its initial position.
[0122] In some implementation examples, the above-mentioned variations are combined according to design requirements.
[0123] Example 2
[0124] This embodiment is an improvement on Embodiment 1 and its variations. The shape and structure of the developing cartridge in Embodiment 2 are basically the same as those in Embodiment 1. The similar parts will not be described again. The following mainly introduces the differences.
[0125] like Figure 8 and Figure 9 As shown, in this embodiment, the protruding direction of the cam portion is opposite to that of the cam portion in Embodiment 1. In this embodiment, there are two cam portions, namely a first cam portion 33b and a second cam portion 34b. The following description uses the first cam portion 33b as an example. The first cam portion 33b protrudes from the end face of the main body portion 31b in a direction close to the first sidewall 11b and can push the force-receiving portion 41b of the transmission member 4b.
[0126] The elastic member 5b applies force to the transmission member 4b in a leftward direction, and the elastic member support portion 51b is located on the right side of the elastic member 5b. The initial position of the transmission member 4b is in the first position, in which the force-receiving portion 41b of the transmission member 4b abuts against the right end face of the main body portion 31b.
[0127] In this embodiment, the component 6b to be detected is configured to swing along the vertical direction of the housing. Specifically, the component 6b to be detected is provided with a force receiving part 61b, a connecting part 62b, and a detection part 63b. The connecting part 62b is pivotally connected to the second end cover 102b. The force receiving part 61b extends from the connecting part 62b toward the transmission member 4b. The force receiving part 61b is also provided with a pressing surface 611b. The transmission member 4b causes the component 6b to rotate about an axis by pressing against the pressing surface 611b. The detection part 63b is located on the other side of the connecting part 62b. When the pressing surface 611b is pushed by the transmission member 4b, the detection part 63b tilts upward to trigger the detection unit 100 of the imaging device.
[0128] Optionally, the direction of movement of the detected unit 63b can be set according to the position of the detected unit 63b relative to the detection unit 100 of the imaging device.
[0129] Next, combine Figure 8 and Figure 9 This section describes the process by which the developing cartridge 10b is detected by the detection unit 100 of the imaging device.
[0130] like Figure 8 As shown, in this embodiment, when the developing cartridge 10b is in an unused state, the transmission member 4b is in the first position (initial position), the elastic member 5b is in an uncompressed state, and the detected member 6b is in a state where the detection unit 100 is not triggered.
[0131] When the imaging device starts operating, the cam member 3b receives driving force and rotates via the second gear part 32b. Under the push of the first cam part 33b, the force-receiving part 41b moves from the root of the first cam part 33b along the second guide surface 36b to the top of the first cam part 33b. At this time, the transmission member 4b is forced to slide to the right. Figure 9 As shown, the transmission member 4b is in the second position, the elastic member 5b is compressed, the transmission member 4b presses against the pressing surface 611b of the detected member 6b, causing the detected member 6b to rotate, and the detection part 63b tilts upward to touch the detection unit 100 of the imaging device.
[0132] As the force-bearing part 41b moves from the top of the first cam part 33b along the first guide surface 35b to the root of the first cam part 33b, under the elastic restoring force of the elastic member 5b, the transmission member 4b is forced to move to the left. The transmission member 4b no longer presses against the detected member 6b, and the detected part 63b of the detected member 6b can move downward under its own gravity and return to its initial state. When the second cam part 34b pushes the force-bearing part 41b of the transmission member 4b, the detected member 6b touches the detection unit 100 a second time, and the detection is finally completed.
[0133] In some embodiments, the developing cartridge is further provided with an elastic reset member that applies an elastic force to the tested member 6b, thereby enabling the tested member 6b to return to its initial state. Specifically, the elastic reset member may be a compression spring that supports the force receiving portion 61b of the tested member 6b in an upward direction, so that the tested member 6b is in its initial position.
[0134] In other implementations, the above-mentioned variations are combined according to design requirements.
[0135] Example 3
[0136] This embodiment is an improvement on Embodiment 1 and its variations. The shape and structure of the developing cartridge in Embodiment 3 are basically the same as those in Embodiment 1. The similar parts will not be described again. The following mainly introduces the differences.
[0137] like Figure 10 and Figure 11 As shown, in this embodiment, the rotation axis of the cam component 3c and the rotation axis of the connecting component 21c are intersecting (including intersecting in the same plane and intersecting after being projected into the same plane).
[0138] Specifically, the rotation axis of the cam component 3c is perpendicular to the rotation axis of the connecting member 21c. The second gear portion 32c of the cam component 3c is a first bevel tooth portion, which meshes with the second bevel tooth portion 38c provided on the gear of the stirring member. The cam portion 33c of the cam component 3c is provided on the upper side of the cam component 3c, and the cam portion 33c extends outward along the radial direction of the main body portion 31c.
[0139] In this embodiment, the clutch mechanism includes a toothed portion 37c disposed on the outer side of the circumference of the main body portion 31c of the cam member 3c. When the toothed portion 37c rotates to face the second bevel tooth portion 38c, the transmission of driving force between the second bevel tooth portion 38c and the first bevel tooth portion 32c is cut off.
[0140] The force-receiving part 41c of the transmission member 4c is located closer to the second sidewall 12c than the cam part 33c. In this embodiment, when the developing cartridge is not in use, the transmission member is in the first position (e.g., Figure 10 (As shown in the image), the force-receiving part 41c abuts against the root of the cam part. When the second gear part 32c of the cam member 3c receives the driving force and rotates, the cam part 33c pushes the force-receiving part 41c, the transmission member 4c slides to the right, driving the detected member 6c to rotate, thereby triggering the detection unit 100 of the imaging device, as shown in the image. Figure 11 As shown, the transmission component 4c is in the second position. As the cam component 3c rotates, the force-bearing part 41c moves from the top of the cam part 33c to the root of the cam part 33c. Under the action of the elastic restoring force of the elastic component 5c, the transmission component 4c slides to the left and drives the detected component 6c to swing. The detected component 6c is removed from the detection unit 100, and the detection is completed.
[0141] In some embodiments, the second bevel gear may be provided on the connecting member 21c, the developing roller gear 22c, the powder feeding roller gear 23c, or the idler wheel 24c.
[0142] In some embodiments, the force-receiving portion 41c of the transmission member 4c is located further away from the second sidewall 12c than the cam portion.
[0143] In other implementations, the above-mentioned variations are combined according to design requirements.
[0144] Example 4
[0145] This embodiment is an improvement on Embodiment 1 and its variations. The shape and structure of the developing cartridge in Embodiment 4 are basically the same as those in Embodiment 1. The similar parts will not be described again. The following mainly introduces the differences.
[0146] like Figure 12a and Figure 12b As shown, in this embodiment, the transmission component 4d is a swing component, and at least a portion of the swing component is capable of moving along the length direction L of the box body 1d.
[0147] The transmission component 4d includes a force-receiving part 41d and a rod part 42d. The middle part of the rod part 42d is connected to the housing 1d in a way that allows it to swing up and down. Such a connection is, for example, through a shaft part connected to a shaft hole. The force-receiving part 41d is located at the first end of the rod part 42d and is positioned above the rotation axis of the main body part 31d, so that the cam part can push the force-receiving part 41d upward.
[0148] The driving component is a cam component 3d. The rotation axis of the cam component 3d is parallel to the rotation axis of the connecting member 21d. The cam portion protrudes along the radial direction of the main body 31d. In this embodiment, there are two cam portions, namely a first cam portion 33d and a second cam portion 34d. The root of the cam portion is formed between the first cam portion 33d and the second cam portion 34d.
[0149] The elastic element 5d is supported at the second end of the rod 42d and is located on the lower side of the second end of the rod 42d.
[0150] The tested component 6d is fixedly connected to the second end of the transmission component 4d so that it can swing with the swing of the transmission component 4d.
[0151] Next, combine Figure 12a and Figure 12b This describes the process by which the developing chamber is detected by the detection unit 100 of the imaging equipment.
[0152] In this embodiment, when the developing cartridge is not in use, the transmission member 4d is in the second position (e.g., Figure 12a As shown, the force-bearing part 41d abuts against the top of the first cam part 33d, the elastic member 5d is in a compressed state, and the detected member 6d is in a state where the detection unit is not triggered.
[0153] When the imaging device starts operating, as the cam component 3d rotates, the force-bearing part 41d of the transmission component 4d moves towards the root along the first guide surface 35d of the first cam part 33d. Under the elastic restoring force of the elastic component 5d, the second end of the rod part 42d rises upward and drives the detected component 6d to move upward. The detected component 6d triggers the detection unit of the imaging device, and the transmission component is in the first position (e.g., Figure 12b (The location shown).
[0154] As the cam component 3d rotates, during the process of the second cam part 34d pushing the force-receiving part 41d of the transmission component 4d, the force-receiving part 41d first moves upward and then downward. Simultaneously, the detected component 6d moves downward to disengage from the detection unit 100 and then moves upward to touch the detection unit 100 again, thereby achieving detection.
[0155] Figure 13a The position state of transmission component 4d when it is in the second position is shown. Figure 13b The diagram shows the position of transmission component 4d when it is in the first position. For example... Figure 13a As shown, when the transmission member 4d is in the second position, the distance from one end of the transmission member 4d to the center of the swing along the length L of the developing cartridge is d2. When the transmission member 4d swings from the second position to the first position, as... Figure 13bAs shown, the distance from one end of the transmission component 4d to the swing center along the length direction L of the developing cartridge is d3, where d3 is less than d2. The distance the one end of the transmission component 4d moves along the length direction of the developing cartridge is the difference between d2 and d3.
[0156] In some embodiments, the force-receiving part 41d may also be located on the lower side of the rotation axis of the main body part 31d, and the detection unit 100 is triggered when the detected part 63d moves downward.
[0157] In other implementations, the above-mentioned variations are combined according to design requirements.
[0158] Example 5
[0159] This embodiment is an improvement on embodiment 4 and its variations. The shape and structure of the developing cartridge in embodiment 5 are basically the same as those in embodiment 4. The similar parts will not be described again. The following mainly introduces the differences.
[0160] like Figure 14a and Figure 14b As shown, in this embodiment, the transmission component 4e is a swing component that can swing in the front-back direction of the developing cartridge, and at least a portion of the swing component can move in the length direction L of the cartridge body 1e.
[0161] The transmission component 4e includes a force-receiving part 41e and a rod part 42e. The middle part of the rod part 42e is connected to the housing 1e in a back-and-forth swinging manner, such as a shaft and shaft hole connection. The force-receiving part 41e is located at the first end of the rod part 42e, in front of the rotation axis of the cam component 3e, so that the cam part can push the force-receiving part 41e forward.
[0162] The rotation axis of the cam member 3e is parallel to the rotation axis of the connecting member 21e, and the cam portion protrudes along the radial direction of the main body 31e. In this embodiment, the cam member 3e also has a first cam portion 33e and a second cam portion 34e, and a root portion of the cam portion is formed between the first cam portion 33e and the second cam portion 34e.
[0163] The elastic element 5e supports the first end of the rod 42e and is located on the front side of the first end of the rod 42e. The detected component 6e is fixedly connected to the second end of the rod 42e and can swing with the swing of the transmission component 4e.
[0164] Next, combine Figure 14a and Figure 14b This describes the process by which the developing chamber is detected by the detection unit 100 of the imaging equipment.
[0165] In this embodiment, the developing cartridge is in an unused state, and the transmission component 4e is in the first position. Figure 14a(As shown in the figure), the force-bearing part 41e abuts against the circumferential side of the cam body, and the elastic element 5e is in an uncompressed state.
[0166] When the imaging device starts operating, the second gear portion 32e of the cam component 3e receives driving force and rotates under the push of the first cam portion 33e, as... Figure 14b As shown, the first cam 33e pushes the force-receiving part 41e, causing the force-receiving part 41e to move forward, and the second end of the transmission member 4e swings backward. The detected member 6e moves backward with the second end of the rod 42e and touches the detection unit 100.
[0167] When the force-receiving part 41e of the transmission member 4e passes the top of the first cam part 33e, under the elastic restoring force of the elastic member 5e, the first end of the rod part 42e moves to the rear of the developing cartridge, and the second end of the rod part 42e drives the detected component 6e to move forward away from the detection unit 100. When the second cam part 34e pushes the force-receiving part 41e, the movement process of the transmission member 4e and the detected component 6e is the same as the movement process when the first cam part 33e pushes the force-receiving part 41e. As a result, the detection unit 100 of the imaging device is triggered again, thereby realizing detection.
[0168] Figure 15a The position state of transmission component 4e when it is in the first position is shown. Figure 15b The diagram shows the position of transmission member 4e when it is in the second position. For example... Figure 15a As shown, when the transmission member 4e is in the first position, the distance d4 from one part a of the transmission member 4e to the swing center along the length L of the developing cartridge is d4. When the transmission member 4e swings from the first position to the second position, as... Figure 15b As shown, the distance from part a of the transmission component 4e to the swing center in the length direction L of the developing cartridge is d5, where d5 is less than d4. The distance that part a of the transmission component e moves in the length direction L of the developing cartridge is the difference between d4 and d5.
[0169] In some embodiments, the cam portion may also be configured to push the transmission member 4e backward.
[0170] In other implementations, the above-mentioned variations are combined according to design requirements.
[0171] Example 6
[0172] like Figures 16 to 22As shown in Embodiment 6, the developing cartridge 10f has a generally rectangular box-shaped body 1f. Its exterior has a first sidewall 11f and a second sidewall 12f along its length. Internally, it contains a powder hopper for containing developer, a developing roller 14f, a powder feeding roller, and a stirring member 15f. The developing roller 14f is positioned on the front side of the developing cartridge 10f in the direction P where it is installed to the imaging device. It is exposed from the front of the box body 1f and faces the photosensitive drum when installed in the imaging device, enabling development. The powder feeding roller faces the developing roller 14f and can deliver developer to the developing roller 14f; the stirring member 15f is used to stir the developer contained in the powder hopper.
[0173] The driving force receiving unit 2f is disposed on the first side (or the first end of the developing cartridge) along the length direction of the cartridge 1f, and is used to receive driving force from the driving transmission component of the imaging device and to transmit rotational driving force to rotating components such as the developing roller 14f. Specifically, in this embodiment, the driving force receiving unit 2f includes a connecting member 21f, a developing roller gear 22f, a powder feeding roller gear 23f, a stirring component gear 24f, and an idler wheel 25f.
[0174] like Figure 17 and Figure 18 As shown, the connecting member 21f is rotatably supported on the first side wall 11f of the housing 1f, and its rotation axis L1 extends along the length of the developing cartridge 10f and is parallel to the rotation axis L2 of the developing roller 14f. The connecting member 21f is provided with a driving force receiving part 211f and a gear part 212f. The driving force receiving part 211f is connected to the driving transmission member and receives the driving force. The gear part 212f can mesh with the developing roller gear 22f, the powder feeding roller gear 23f, and the idler wheel 25f to transmit rotational driving force to the developing roller gear 22f, the powder feeding roller gear 23f, and the idler wheel 25f. The developing roller gear 22f and the powder feeding roller gear 23f are respectively provided at the ends of the developing roller 14f and the powder feeding roller to drive the developing roller 14f and the powder feeding roller to rotate. The stirring member gear 24f is provided at the end of the stirring member 15f and meshes with the idler wheel 25f to drive the stirring member 15f to rotate.
[0175] like Figures 20 to 22As shown, the developing cartridge 10f includes a tested component 6f and a support member. In this embodiment, the support member is a rotating body 61f, which is disposed at the second end of the developing cartridge 10f along its length (opposite to the first end in the length direction of the developing cartridge 10f). The rotating body 61f can rotate by receiving the driving force transmitted by the connecting member 21f. The rotation axis L3 of the rotating body 61f intersects the rotation axis L1 of the connecting member 21f and the rotation axis L2 of the developing roller 14f (it can be a spatial intersection or an intersection on the same plane), that is, the rotation axis L3 is not parallel to the rotation axis L1 of the connecting member 21f. Projected onto a plane parallel to the rotation axes L1 and L3, the rotation axis L3 of the rotating body 61f intersects the rotation axis L1 of the connecting member 21f. The rotating body 61f includes a second mounting part 611f and a rotating support part 612f, which is rotatably supported on the developing cartridge 10f.
[0176] The component 6f being detected can move with the rotation of the rotating body 61f and can touch the transmission mechanism to make the transmission mechanism rotate or swing, so that it can be detected by the detection unit of the imaging device.
[0177] like Figures 17 to 22 As shown, the developing cartridge 10f in this embodiment further includes a driving component 3f and a transmission component. The driving component 3f includes a first transmission body 31f and a second transmission body 32f, wherein the second transmission body 32f can receive driving force from the driving force receiving unit 2f, and the first transmission body 31f receives driving force from the second transmission body 32f; the transmission component is a flexible transmission component 4f, which connects the first transmission body 31f and the rotating body 61f to drive the rotating body 61f to rotate.
[0178] Specifically, in this embodiment, the first transmission body 31f is provided with a first rotational force receiving part 311f for receiving rotational force and a first mounting part 312f for mounting the flexible transmission member 4f. The first rotational force receiving part 311f may be a gear part, and the first mounting part 312f is preferably the shaft part of the first transmission body 31f. Preferably, the rotation axis L4 of the first transmission body 31f is perpendicular (including spatial perpendicularity and perpendicularity in the same plane) to the rotation axis L1 of the connecting member 21f and the axis L2 of the developing roller 14f, and parallel to the mounting direction P of the developing cartridge 10f.
[0179] The second transmission body 32f is provided with a second rotational force receiving part 321f and a rotational force transmitting part 322f. The rotation axis L5 of the second transmission body 32f is parallel to the rotation axis L1 of the connecting member 21f and perpendicular to the rotation axis L4 of the first transmission body 31f. The second rotational force receiving part 321f is used to receive rotational driving force from the driving force receiving unit 2f. The second rotational force receiving part 321f may be a gear part that meshes with the stirring member gear 24f, and the rotational force transmitting part 322f may be a screw part that cooperates with the first rotational force receiving part 311f.
[0180] Preferably, both the first transmission body 31f and the second transmission body 32f are rotatably disposed on the first side of the cartridge 1f (the first end of the developing cartridge), and are located on the same side of the cartridge 1f as the connecting member 21f. The first rotational force receiving part 311f of the first transmission body 31f is preferably a first gear part 311f, and the first mounting part 312f is an annular groove disposed on the shaft of the first transmission body 31f, the annular groove rotating with the rotation of the first gear part 311f.
[0181] The second rotational force receiving part 321f of the second transmission body 32f is preferably the second gear part 321f, and the rotational force transmitting part 322f is preferably the screw part 322f that meshes with the first gear part 311f.
[0182] The second transmission body 32f is rotatably supported on the first sidewall 11f. Its second gear portion 321f meshes with the stirring member gear 24f to receive driving force, and its first gear portion 311f is located above the screw portion 322f and meshes with the screw portion 322f to receive driving force. Along the mounting direction of the developing cartridge 10f, the first mounting portion 312f of the first transmission body 31f is located downstream of the first gear portion 311f.
[0183] The flexible transmission element 4f connects the first transmission body 31f and the rotating body 61f to transmit driving force to the rotating body 61f. The flexible transmission element 4f is movable along the length L of the developing cartridge 10f. As an example, the flexible transmission element 4f is preferably a flexible belt, which can be a leather belt, rubber belt, etc. One end of the flexible belt is fitted onto the first mounting portion 312f of the first transmission body 31f, and the other end is fitted onto the second mounting portion 611f of the rotating body 61f (which can be a shaft portion or an annular groove on the rotating body 61f), so that when the first transmission body 31f rotates, it drives the flexible belt to rotate, thereby driving the rotating body 61f to rotate. The detected component 6f moves as the rotating body 61f rotates.
[0184] While the flexible transmission component 4f rotates, it can also move along the length direction L of the developing cartridge 10f. After the flexible transmission component 4f moves a preset distance, each part of the flexible transmission component 4f can also move a preset distance along the length direction L of the developing cartridge 10f. In other words, while the flexible transmission component 4f rotates as a whole, each part of the flexible transmission component 4f can also move along the length direction L of the developing cartridge 10f.
[0185] The flexible belt is configured to have friction with the second mounting portion 611f on the first transmission body 31f and the rotating body 61f, so that the first transmission body 31f drives the flexible belt, and the flexible belt drives the rotating body 61f. Such friction can be achieved by providing rough surfaces on the flexible belt, the first transmission body 31f, and the rotating body 61f, or by using a mating structure of protrusions and recesses, or by using a toothed mating method, etc.
[0186] In this embodiment, the first transmission body 31f, the second transmission body 32f, and the flexible transmission component 4f constitute a transmission direction-changing unit. This transmission direction-changing unit can connect the driving force receiving unit 2f and the rotating body 61f to realize the transmission of driving force. The transmission direction-changing unit can transmit the rotational force of the first object (such as the driving force receiving unit) in the first direction to the second object, so that the second object (such as the detected component) moves in the second direction, and the rotation axis of the first object intersects the movement direction of the second object (it can be spatial intersection or intersection on the same plane). The movement can be linear motion, rotation, or curvilinear motion.
[0187] Further, refer to Figure 21 In this embodiment, the transmission reversing unit further includes a direction changing element 64f. Specifically, this direction changing element can be a second support member, and the flexible belt is supported by the second support member and bends downward from the upper side to change direction. Optionally, the direction changing element 64f can also be a roller.
[0188] In this embodiment, the component to be detected 6f is disposed on the outer surface of the flexible belt and protrudes from the outer surface of the flexible belt. One or more components to be detected 6f may be provided. In this embodiment, multiple components to be detected 6f are spaced apart by a preset distance. When the flexible belt drives the rotating body 61f to rotate, the component to be detected 6f can come into contact with the transmission mechanism of the imaging device, thereby causing the transmission mechanism to swing, and the imaging device can detect the developing cartridge 10f.
[0189] Optionally, the component 6f to be tested can also be mounted on the rotating body 61f, and can rotate with the rotating body 61f and contact the transmission mechanism. Optionally, the component 6f to be tested can be detachably mounted on the flexible belt or integrally formed, and the component 6f to be tested can protrude from the surface of the flexible belt.
[0190] In this embodiment, the developing cartridge 10f may further include a first end cap 101f and a second end cap 102f located on a first side and a second side of the cartridge body 1f, respectively. The first end cap 101f covers the outer side of the driving force receiving unit 2f, and the connecting member 21f of the driving force receiving unit 2f can be exposed through the first hole 1011f of the first end cap 101f. The second end cap 102f covers the second side of the cartridge body 1f and is provided with an exposure portion 1021f so that the detected component 6f can be exposed through the exposure portion 1021f. The rotating body 61f can be rotatably supported on the inner side of the second end cap 102f.
[0191] Next, combine Figures 16-22 This section describes the process by which the developing cartridge 10f is detected by the detection unit of the imaging device.
[0192] The user installs the developing cartridge 10f into the imaging device, and the connector 21f connects to the drive transmission component of the imaging device. When the imaging device starts operating, the connector 21f receives the rotational drive force and rotates, transmitting the rotational force to the second transmission body 32f. The second transmission body 32f rotates and drives the first transmission body 31f to rotate through the screw part 322f. The rotation of the first transmission body 31f drives the flexible belt 4f to rotate, which in turn drives the rotating body 61f of the detected mechanism 3 to rotate. As a result, the detected component 6f on the flexible belt 4f touches the transmission mechanism of the imaging device and is thus detected by the imaging device.
[0193] In some other embodiments, the second transmission body 32f can receive rotational driving force from the stirring member gear 24f, as well as from the connecting member 21f, the developing roller gear 22f, the powder feeding roller gear 23f, or the idler wheel 25f.
[0194] In some other embodiments, the second transmission body 32f may also be one of the following: a connecting member 21f having a screw portion 322f, a developing roller gear 22f, a powder feeding roller, and a powder feeding roller gear 23f.
[0195] In other embodiments, the rotational force transmitting part and the first rotational force receiving part can also be bevel gear transmission structures (or bevel gear parts), that is, replacing the transmission method of the screw part and the gear with the transmission method of bevel gears. Specifically, the rotational force transmitting part is conical, with the top of the cone being further away from the first sidewall 101f than the bottom, and bevel teeth are provided on its side. The first rotational force receiving part is provided with bevel teeth, and its rotation axis is configured to be perpendicular to the rotation axis of the rotational force transmitting part.
[0196] In some other embodiments, the rotational force transmitting part and the first rotational force receiving part can also be connected by a linkage structure so that the rotational axis of the first transmission body and the rotational axis of the second transmission body intersect (that is, they are not parallel).
[0197] In other embodiments, the driving component and transmission reversing unit may omit the second transmission body. The rotation axis of the first transmission body is configured to be parallel to the rotation axis of the connecting member. The flexible belt is sleeved on the first mounting portion of the first transmission body, and the other end is sleeved on the second mounting portion of the rotating body. Preferably, with the first transmission body and the rotating body as ends, the flexible belt can be divided into a first belt body and a second belt body. In this variation, the first belt body and the second belt body are not parallel and are intersecting, so as to drive the rotating body whose rotation axis is intersecting the rotation axis of the first transmission body to rotate. Alternatively, such a first transmission body may be a connecting member with a first mounting portion, a developing roller gear, a powder feeding roller gear, a stirring component gear, or an idler wheel.
[0198] In other implementations, the flexible transmission component can also be a chain, rubber belt, etc.
[0199] In other embodiments, the support member can also be a component fixed to the housing. For example, the rotating body 61f in this embodiment can be replaced with a fixing member, the two ends of which are fixedly connected to the housing 1f, and the fixing member has a smooth surface. A flexible band is fitted on the smooth surface so that it can slide relative to the fixing member, thereby allowing the detected component disposed on the flexible band to move and touch the transmission mechanism of the imaging device.
[0200] In some other embodiments, depending on the type of imaging device, the rotation axis L3 of the rotating body 61f and the rotation axis L1 of the connecting member 21f can be at different angles (e.g., 90 degrees, 60 degrees, or 30 degrees, etc.). This structure greatly reduces the accuracy requirements and improves the design flexibility.
[0201] In other embodiments, depending on the type of imaging device, the rotating body 61f can be positioned at different locations within the developing chamber, such as on the first side, above, below, or behind the chamber body 1f, greatly improving design flexibility.
[0202] In other embodiments, the developing cartridge is further provided with a transmission disconnection mechanism (clutch mechanism). The transmission disconnection mechanism is used to cut off the driving force transmitted from the first transmission body to the component being tested, causing the component being tested to stop moving. Specifically, for a structure in which the first transmission body and the flexible belt are driven by friction, the transmission disconnection mechanism may include a smooth surface disposed on the inner side of the flexible belt. When the smooth surface moves to a position that contacts the first transmission body 31f, the first transmission body 31f cannot transmit driving force to the flexible belt, and the flexible belt stops rotating.
[0203] In other implementations, the above-mentioned variations can be combined according to design requirements.
[0204] The developing cartridge with the above structure transmits driving force through a flexible transmission component, allowing for diverse placement of the components being inspected. The rotation axis L3 of the rotating body can be at an angle to the rotation axis L1 of the connecting component 21f, meaning parallel placement is not required, and the angle can be adjusted as needed. This also improves the flexibility of the imaging device's detection unit placement. The developing cartridge 10f with the above structure effectively solves the speed difference problem that occurs during long-distance transmission by using a flexible transmission component 4f.
[0205] The developing cartridge 10f with the above structure, compared to the direct transmission of driving force through gears and rotating body 61f, requires strict consideration of the transmission ratio when gears are used. When controlling the rotational speed of rotating body 61f, multiple gears are needed for speed reduction, increasing the number of components and production costs. The rotating body 61f and the first transmission body 31f are connected by a flexible transmission component 4f. When the transmission speed needs to be reduced, only the diameters of the rotating body 61f and the first transmission body 31f need to be adjusted, greatly reducing design costs.
[0206] When the developing cartridge 10f with the above structure requires multiple touches to the transmission mechanism of the imaging device, multiple detection components 6f can be set on the flexible transmission component or the rotating body 61f, or the number of rotations can be increased; this structure is also advantageous when a longer interval between each touch is required.
[0207] Example 7
[0208] like Figure 23 and Figure 24 As shown, the developing cartridge of this embodiment has a basically the same shape and structure as the developing cartridge of embodiment 6. The similarities will not be repeated here. The differences will be introduced below.
[0209] In this embodiment, the flexible transmission component is a flexible rope 4f1. One end of the flexible rope 4f1 is wound or connected to the first transmission body 31f, and the other end is wound around the rotating body 61f. The number of rotations of the rotating body 61f can be controlled by controlling the number of turns of the flexible rope 4f1 wound around it. The flexible rope 4f1 is wound in opposite directions on the first transmission body 31f and the rotating body 61f.
[0210] When the developing cartridge 10f is installed into the imaging device, and the connecting member 21f receives a driving force to rotate, the first transmission body 31f receives a driving force to rotate and pulls the flexible rope 4f1. Due to the pull of the flexible rope 4f1, the rotating body 61f begins to rotate, causing the detected component 6f, which is mounted on the rotating body 61f, to come into contact with the transmission mechanism of the imaging device. In this structure, as the first transmission body 31f and the rotating body 61f rotate, the number of turns of the first transmission body 31f increases, while the number of turns of the rotating body 61f decreases.
[0211] In other embodiments, a direction-changing element can be provided between the first transmission body 31f and the rotating body 61f to change the direction of transmission. Specifically, the direction-changing element can be a roller, with the flexible rope 4f1 passing around the roller to change the transmission direction before connecting to the rotating body 61f. Alternatively, the direction-changing element can also be a fixed second support member, which serves as a fulcrum, with the flexible rope 4f1 passing around this fulcrum to change its direction.
[0212] In other embodiments, the flexible transmission component can also be a metal wire such as steel wire or iron wire, or a chain.
[0213] In other embodiments, the developing cartridge is also provided with a transmission disconnection mechanism (clutch mechanism) to cut off the driving force transmitted from the driving force receiving unit to the component being tested, thereby stopping the movement of the component being tested. In this embodiment, the flexible rope or steel wire may not be bound to the rotating body 61f. As a result, as the rotating body 61f rotates, the flexible rope eventually detaches from the rotating body 61f, the rotating body stops rotating, and the component being tested stops rotating.
[0214] In Example 7, other structures and variations of the developing cartridge can be found in the description of Example 6, and will not be repeated here.
[0215] Example 8
[0216] This embodiment is an improvement on Embodiment 1 and its variations. The shape and structure of the developing cartridge in Embodiment 8 are basically the same as those in Embodiment 1. The similar parts will not be described again. The following mainly introduces the differences.
[0217] like Figure 25 As shown, in this embodiment, the driving component is a Geneva component 3g, whose rotation axis is parallel to the rotation axis of the connecting component. The Geneva component 3g includes a cylindrical main body 31g, and the outer circumferential surface of the main body 31g is provided with a guide groove 311g and a second gear 32g that can mesh with the driving force receiving unit.
[0218] The working part of the drive member is disposed in the guide groove 311g (or forms part of the guide groove), and the force-receiving part 41g of the transmission member 4g is embedded in the guide groove 311g along the radial direction of the main body 31g, and can move along the guide groove 311g when the Geneva wheel member 3g rotates; preferably, the embedded part can be in the form of a cylinder that matches the guide groove 311g.
[0219] In this embodiment, there are two functional parts, namely a first functional part 33g and a second functional part 34g, which have the same shape and structure.
[0220] Taking the first actuating part 33g as an example, the first actuating part 33g extends away from the first sidewall along the rotation axis of the Geneva member 3g, so as to push the force-receiving part 41g of the transmission member 4g when the Geneva member 3g rotates.
[0221] Next, combine Figure 25 This section describes the process by which the developing cartridge is detected by the detection unit of the imaging equipment.
[0222] In this embodiment, when the developing cartridge is not in use, the force-bearing part 41g of the transmission member 4g abuts against the side wall 312g of the guide groove 311g, and the detected component 6g is in a state of separation from the detection unit.
[0223] When the Geneva wheel component 3g rotates under the driving force, the force-receiving part 41g, pushed by the first action part 33g, first moves from the root of the first action part 33g to the top of the first action part 33g, and then moves from the top of the first action part 33g to the root of the first action part 33g. As a result, the transmission part 4g slides to the left and then to the right. Simultaneously, the component being detected 6g rotates under the drive of the transmission part 4g and touches the detection unit of the imaging device before returning to its initial position. As the Geneva wheel component 3g rotates, the second action part 34g pushes the force-receiving part 41g and repeats the cooperation process between the first action part 33g and the force-receiving part 41g. The component being detected 6g can touch the detection unit again, and finally the detection is completed.
[0224] The developing cartridge with the above structure can also omit the setting of the elastic element, and the transmission element relies on the guide groove to prevent the force-bearing part from disengaging from the groove wheel component 3g.
[0225] Example 9
[0226] This embodiment is an improvement on embodiment 4 and its variations. The shape and structure of the developing cartridge in embodiment 9 are basically the same as those in embodiment 4. The similar parts will not be described again. The following mainly introduces the differences.
[0227] like Figure 26 and Figure 27 As shown, in this embodiment, the driving component is a Geneva component 3h, whose rotation axis is parallel to the rotation axis of the connecting component. The Geneva component 3h includes a cylindrical main body 31h, a guide groove 311h is provided on one end face of the main body 31h near the first sidewall, and a second gear 32h is provided on its outer circumferential surface, which can mesh with the driving force receiving unit.
[0228] The working part of the drive member is provided in the guide groove 311h (or forms part of the guide groove), and the force-bearing part 41h of the transmission member 4h is embedded in the guide groove 311h along the rotation axis of the main body 31h, and can move along the guide groove 311h when the Geneva wheel member 3h rotates.
[0229] In this embodiment, there are two working parts, namely a first working part 33h and a second working part 34h with the same shape and structure. Taking the first working part 33h as an example, the first working part 33h extends in the radial direction of the main body part 31h so as to push the force-receiving part 41h of the transmission member 4h when the Geneva member 3h rotates.
[0230] The transmission component 4h can swing up and down around the shaft 46h located in the middle. It includes a rod 42h and a force-bearing part 41h. The end of the rod 42h away from the Geneva component 3h is fixedly connected to the component 6h being tested.
[0231] Next, combine Figure 26 and Figure 27 This section describes the process by which the developing cartridge is detected by the detection unit of the imaging equipment.
[0232] In this embodiment, when the developing cartridge is not in use, the transmission component 4h is in the second position. In this position, the force-receiving part 41h is located on top of the first action part 33h, and the detected component 6h is in a state of not touching the detection unit.
[0233] When the grooved wheel component 3h receives driving force and rotates, the force-bearing part 41h moves from the top of the first action part 33h to the root of the first action part 33h, the first end of the rod part 42h moves downward, the second end of the rod part is lifted upward and drives the detected component 6h to move upward, and the detected component 6h triggers the detection unit of the imaging device.
[0234] During the process of the second action part 34h pushing the force-receiving part 41h of the transmission part 4h, the force-receiving part 41h first moves upward and then downward. Simultaneously, the detected component 6h moves downward to get away from the detection unit and then moves upward to touch the detection unit again, thereby realizing the detection.
[0235] The developing cartridge with the above structure can omit the setting of the elastic element, and the transmission element relies on the limiting effect of the guide groove to restrict its disengagement from the groove wheel component for 3 hours.
[0236] Optionally, the number and shape of the action parts can be changed as needed; for example, one or more action parts can be set; multiple action parts can have different shapes and structures, etc.
[0237] Example 10
[0238] This embodiment is an improvement on Embodiment 1 and its variations. The shape and structure of the developing cartridge 10j in Embodiment 10 are basically the same as those of the developing cartridge 10a in Embodiment 1. The similar parts will not be described again. The following mainly introduces the differences.
[0239] like Figures 28 to 34As shown, the driving component in this embodiment is configured as a cam component, and the developing cartridge 10j is provided with a clutch mechanism for cutting off the transmission of driving force to the detected component 6j at a preset time. The clutch mechanism includes a pushing structure and a retracting structure. The pushing structure is used to force at least a portion of the cam component 3j to move, and the retracting structure allows the movement of the at least a portion to have displacement space. Specifically, the retracting structure includes a first protrusion 81j provided at one end of the cam component 3j near the first sidewall 11j and a clearance portion 82j located on the support member 87j, specifically the clearance portion being an opening 82j.
[0240] The first protrusion 81j can move against the surface of the support member 87j. When the first protrusion 81j moves to the opening 82j, the first protrusion 81j falls into the opening 82j under the action of the pushing structure, thereby realizing the movement of the cam member 3j.
[0241] The support member 87j is fixedly connected to or replaces the first sidewall. The pushing structure includes a second protrusion 83j provided on the first end cover 101j and a third protrusion 85j provided on the end of the cam member 3j away from the first sidewall 11j. The protrusion directions of the second protrusion 83j and the third protrusion 85j are opposite. When the cam member 3j rotates, the third protrusion 85j can move along the pressing surface of the second protrusion 83j to the top of the second protrusion 83j, so as to force the cam member 3j to move along the length direction of the developing cartridge 10j to disconnect the transmission of driving force.
[0242] The cooperating relationship between the pushing structure and the retracting structure is as follows: before the second protrusion 83j pushes the third protrusion 85j, the first protrusion 81j moves to the opening 82j first. Alternatively, when the second protrusion 83j pushes the third protrusion 85j, the first protrusion 81j moves to the opening 82j simultaneously. With this structure, the developing cartridge 10j can omit the elastic element, resulting in a simpler structure and easier assembly.
[0243] The cam member 3j in this embodiment further includes a main body 31j, a cam portion 33j, and a rotational force receiving portion 313j. The main body 31j is generally cylindrical, and a flange portion 311j is provided on its outer circumference. A third protrusion 85j protrudes outward from the side of the cam member 3j away from the first sidewall 11j, and can abut against the inner side surface of the first end cover 101j. The first protrusion 81j protrudes from the main body 31j toward the first sidewall 11j. The cam portion 33j is provided on the side of the flange portion 311j near the first sidewall 11j, and protrudes toward the first sidewall 11j so as to cooperate with the transmission member 4j. The rotational force receiving portion 313j can protrude from the outer circumference of the main body 31j along the radial direction of the main body 31j to receive driving force. The second gear component 32j includes a hollow part 321j, a gear part 322j, and a rotational force transmission part 323j. The hollow part 321j is cylindrical and hollow, and can be fitted onto the outside of the cam component 3j.
[0244] The rotational force transmission part 323j protrudes from the inner wall of the hollow part 321j along the radial direction of the second gear component 32j and can engage with the rotational force receiving part 313j of the cam component 3j. When the second gear component 32j rotates, the rotational force transmission part 323j drives the rotational force receiving part 313j to rotate. When the cam component 3j moves along the length direction of the developing cartridge 10j, the rotational force transmission part 323j and the rotational force receiving part 313j can disengage in the length direction of the developing cartridge, interrupting the transmission of rotational driving force.
[0245] In this embodiment, the developing cartridge is further provided with a limiting part that restricts the movement of the second gear component 32j. Specifically, the limiting part is a protrusion 116j provided on the first sidewall 11j. The protrusion 116j abuts against the end of the second gear component 32j near the first sidewall 11j, which can restrict the second cam component 32j from moving with the cam component 3j when the cam component 3j moves relative to the second gear component 32j, so that the rotational force transmission part 323j and the rotational force receiving part 313j can be better separated. Preferably, multiple limiting parts can be provided, and the limiting parts can be provided not only on the sidewall but also on the end cap.
[0246] The upper side of the box body 1j is provided with a sliding groove 16j, and the transmission component 4j is slidably accommodated in the sliding groove 16j. Specifically, the upper surface of the transmission component 4j is flush with or lower than the upper surface of the box body 1j.
[0247] The developing cartridge 10j is also provided with a covering portion 7j that at least partially covers the transmission member 4j. In this embodiment, the covering portion 7j is elongated and can be snapped onto the cartridge body 1j to cover the transmission member 4j.
[0248] Specifically, the cover portion 7j has a snap-fit portion 71j, a first exposed portion 72j, and a second exposed portion 73j at both ends. The snap-fit portion 71j at both ends snaps onto the housing 1j to fix the cover portion 7j. The first exposed portion 72j and the second exposed portion 73j are configured as openings, and one end of the transmission member 4j can extend from the first exposed portion 72j and cooperate with the cam member 3j. The detected portion 63j of the detected member 6j is exposed from the second exposed portion 73j so that it can cooperate with the detection unit of the imaging device.
[0249] The component 6j being tested is supported on the second end of the cover 7j in a manner that allows it to swing in the up-down direction. The second end of the cover 7j is provided with a receiving cavity 75j to receive part of the component 6j being tested.
[0250] Specifically, the connecting part 62j of the component being tested 6j is oscillatingly connected to the covering part 7j via a pivot. The pivot axis of the connecting part 62j is located above the force receiving part 61j. The component being tested 63j is located below the pivot axis and, when installed in the imaging device, is located below the transmission mechanism 200j of the detection unit. When the component being tested 63j oscillates up and down, it can trigger the transmission mechanism 200j.
[0251] In this embodiment, the second end of the transmission member 4j further includes a bent section 46j, which bends downward and connects to the drive section 47j. The drive section 47j of the transmission member 4j extends along the length of the developing cartridge 10j. The detected member 6j is oscillatingly supported on the cover section 7j. The force receiving section 61j is located below the oscillation axis of the connecting section 62j. When the drive section 47j of the transmission member 4j triggers the force receiving section 61j of the detected member 6j, the detected member 6j oscillates, and the detected section 63j rises upward to trigger the detection unit so that it can be detected.
[0252] In this embodiment, when the developing cartridge 10j is installed in the imaging device, the detected part 63j of the detected component 6j is pressed by the transmission mechanism 200j (the transmission mechanism has elastic force), and the force receiving part 61j of the detected component 6j pushes the transmission member 4j to the right so that the transmission member 4j is firmly pressed against the flange part 311j of the cam component 3j.
[0253] When the cam portion 33j of the cam component 3j pushes the transmission component 4j, the transmission component 4j moves to the right side of the developing cartridge 10j, thereby pushing the detected component 6j to rotate. The detected portion 63j of the detected component 6j moves upward to press against the transmission mechanism 200j of the detection unit to rotate, thereby enabling it to be detected.
[0254] When the force-bearing part 41j of the transmission member 4j moves from the top of the cam part 33j to the root, under the pressure of the transmission mechanism 200j, the detected component 6j pushes the transmission member 4j to move to the left side of the developing cartridge 10j.
[0255] Next, combine Figures 35a to 35c This diagram illustrates the coordination relationship between the components of the developing cartridge 10j during the imaging process.
[0256] like Figure 35a As shown, when the developing cartridge 10j is installed in the imaging device, the detected part 63j of the detected component 6j is pressed by the transmission mechanism 200j, the transmission component 4j presses against the cam component 3j, the third protrusion 85j abuts against the inner wall of the first end cover 101j, and the first protrusion 81j abuts against the support component 87j.
[0257] like Figure 35b As shown, when the cam part 33j pushes the transmission member 4j, the transmission member 4j pushes the detected member 6j, and the detected part 63j of the detected member 6j swings upward and pushes the transmission mechanism 200j, thereby realizing the detection.
[0258] like Figure 35c As shown, when the cam component 3j rotates and the cam part 33j disengages from the transmission component 4j, the transmission mechanism 200j elastically restores the pressure of the detected part 63j downwards to return to the initial position.
[0259] When the second protrusion 83j presses against the third protrusion 85j, the first protrusion 81j is located at the opening 82j, thereby forcing the cam member 3j to move to the right. The rotational force receiving part 313j of the cam member 3j is disconnected from the rotational force transmitting part 323j of the second gear member 32j, the transmission of rotational force is interrupted, and the detection is completed.
[0260] The developing cartridge 10j with the above-described structure is provided with a sliding groove 16j, which improves the sliding effect of the transmission component 4j and reduces external contact and interference. The developing cartridge 10j is provided with a cover 7j, which effectively protects the transmission component 4j and the component being tested 6j from external collisions and interference. In addition, the developing cartridge 10j of this embodiment can omit the second end cap, reducing the number of parts and lowering production costs.
[0261] The developing cartridge 10j in this embodiment also includes a toner filling port 106j and a filling cover 107j. The toner filling port is located on the second side wall 12j of the developing cartridge and communicates with the toner hopper. A chip and a chip holder may also be provided at the first end of the developing cartridge.
[0262] In some embodiments, the second protrusion 83j can move along the pressing surface of the third protrusion 85j to the top of the third protrusion 85j, so as to force the cam member 3j to move along the length direction of the developing cartridge 10j.
[0263] In some embodiments, the second gear component 32j is integrally formed or fixedly connected to the cam component 3j. When the cam component 3j moves along the length direction of the developing cartridge 10j, the second gear component 32j disengages from the idler wheel 24j of the driving force receiving unit, thereby interrupting the transmission of driving force.
[0264] In some embodiments, the second protrusion 83j may not be provided on the end cap, but on a component that is fixedly connected to the housing.
[0265] In some implementations, the detected part does not come into contact with the transmission mechanism 200j when the developing cartridge is first loaded into the imaging device.
[0266] In some embodiments, the developing cartridge is provided with a resilient reset element so that the transmission element returns to its initial position when not acted upon by the cam.
[0267] In some implementations, a rack structure is used instead of a cam component. This can be achieved by providing a protrusion on the rack to drive the transmission component. The rack receives driving force through its teeth, causing it to move, and then the protrusion drives the transmission component to move.
[0268] In some embodiments, the pushing structure can also be a combination structure of a spiral groove and a protrusion. For example, a spiral groove extending along the length of the developing cartridge is provided on the end cap, and a protrusion that cooperates with the spiral groove is provided on the cam member. When the cam member rotates, the protrusion moves along the spiral groove, thereby realizing movement in the length of the developing cartridge.
[0269] Example 11
[0270] This embodiment is an improvement on embodiment 10 and its variations. The shape and structure of the developing cartridge 10m in embodiment 11 are basically the same as those of the developing cartridge 10j in embodiment 10. The same parts will not be described again. The following mainly introduces the differences.
[0271] like Figure 36 and Figure 37 As shown, the developing cartridge 10m is equipped with a clutch mechanism, specifically including a notch 312m. The notch 312m is specifically located on the flange 311m. The cam 33m protrudes from the flange 311m along the length of the developing cartridge 10m in a direction away from the first sidewall 11m. The flange 311m also has a notch 312m. When the force-bearing part 41m of the transmission member 4m falls into the notch 312m, the cam member 3m disengages the force transmission to the transmission member 4m.
[0272] The transmission component 4m is rod-shaped, with one end abutting against the flange 311m of the cam component 3m so that it can be driven by the cam part 33m, and the other end connecting to the detected component 6m so that it can drive the detected component 6m to move.
[0273] The tested component 6m is supported on the second end of the cover in a manner that allows it to swing in the up-down direction. Specifically, the force receiving part 61m of the tested component 6m extends upward and is inserted into the opening or groove at the second end of the transmission member 4m, so that the tested component 6m can be driven when the transmission member 4m moves left and right.
[0274] The connecting part 62m of the component being tested 6m is oscillatingly connected to the cover part by means of a rotating shaft. The swing shaft of the connecting part 62m is located below the force receiving part 61m. The component being tested 63m is located below the force receiving part 61m and is located below the transmission mechanism 200m of the detection unit when it is installed in the imaging device. The transmission mechanism 200m can be triggered when the component being tested 63m swings up and down.
[0275] In this embodiment, when the developing cartridge 10m is installed in the imaging device, the detected part 63m of the detected component 6m is pressed by the transmission mechanism 200m, and the force receiving part 61m of the detected component 6m pushes the transmission member 4m to the right so that the transmission member 4m is firmly pressed against the cam component 3m.
[0276] Next, combine Figures 38a to 38c Describe the coordinated actions of each component during the process of the developing cartridge being inspected by the imaging equipment.
[0277] like Figure 38a As shown, with the developing cartridge 10m installed in the imaging device, the detected part 63m of the detected component 6m is pressed by the transmission mechanism 200m, and the transmission component 4m presses against the flange part 311m of the cam component 3m.
[0278] like Figure 38b As shown, when the cam part 33m of the cam component 3m pushes the force receiving part 41m of the transmission component 4m, the transmission component 4m moves to the left side of the developing cartridge 10m, thereby driving the force receiving part 61m of the detected component 6m to rotate. The detected part 63m of the detected component 6m moves upward to press the transmission mechanism 200m of the detection unit to rotate, thereby being detected.
[0279] like Figure 38c As shown, when the force-bearing part 41m of the transmission component 4m moves from the top of the cam part 33m to the root, under the pressure of the transmission mechanism 200m, the detected component 6m drives the transmission component 4m to move to the right side of the developing cartridge 10m.
[0280] When the force-bearing part 41m of the transmission component 4m moves to the notch 312m, under the force of the transmission mechanism 200m, the detected component 6m drives the force-bearing part 41m of the transmission component 4m to fall into the notch 312m and move to the right side of the developing cartridge 10m. The cam component 3m continues to rotate, and the force-bearing part 41m is no longer driven by the cam part 33m, and the transmission of force is interrupted.
[0281] The developing cartridge with the above structure has a simple clutch mechanism and low manufacturing cost.
[0282] Example 12
[0283] This embodiment is an improvement on the foregoing embodiments and their variations. The shape and structure of the developing cartridge 10k in embodiment 12 are basically the same as those of the developing cartridge in the foregoing embodiments. The same parts will not be described again. The following mainly introduces the differences.
[0284] like Figures 39 to 41 As shown, the developing cartridge 10k in this embodiment is also provided with a chip 91 and a chip mounting bracket 92 for mounting the chip 91. The chip mounting bracket 92 can be mounted onto the cartridge body 1k. Specifically, the chip 91 and the chip mounting bracket 92 are located at the first end (also the drive end) of the developing cartridge 10k, which is further away from the developing roller 14k than the connecting member 21k.
[0285] In some embodiments, the developing cartridge 10k is detachably mounted into a drum housing containing a photosensitive drum, and the developing cartridge 10k and the drum housing are then mounted together into an imaging device. The drum housing also includes a pressure-applying component, a locking component, and a separation component. The pressure-applying component applies force to the developing cartridge 10k mounted in the drum housing, causing the developing roller 14k and the photosensitive drum to contact or approach each other for developing operations. The locking component is used to lock and unlock the developing cartridge 10k mounted in the drum housing; specifically, the locking component is a rotatable part including a locking portion and a pushing portion. The separation component receives the force from the separation mechanism of the imaging device and pushes the developing cartridge 10k to move, so that when no imaging operation is being performed, the developing roller 14k moves away from the photosensitive drum, and the developing roller 14k and the photosensitive drum separate.
[0286] A locking part 96, a pressing part 97, a pushing part 109, and a separation force receiving part 98 are provided on the second side wall 12k of the developing cartridge 10k. The locking part 96 protrudes from the rear side of the second side wall 12k so as to engage with the locking member on the drum cartridge when the developing cartridge 10k is installed in the drum cartridge. The pressing part 97 is used to receive the force of the pressure member so that the developing roller 14k and the photosensitive drum come into contact or move closer to each other. Specifically, the pressing part 97 is located on the rear side of the cartridge 1k and protrudes from the rear side, and is located at a position further rear than the locking part 96. The separation force receiving part 98 protrudes from the second side wall 12k and is used to receive the force of the separation member so that the developing cartridge 10k moves away from the photosensitive drum, thereby separating the photosensitive drum and the developing roller 14k; the separation force receiving part 98 is closer to the developing roller 14k than the locking part 96. The force exerted by the pushing part of the locking member on the pushed part 109 causes the developing cartridge to swing, thereby causing the locked part 96 to disengage from the locking part. Specifically, the pushing part pushes the pushed part 109 from below, and the pushed part 109 is located between the locked part 96 and the separation force receiving part 98.
[0287] When projected along the length of the developing cartridge 10k, the separation force receiving part 98 is located near the line connecting the rotation center of the developing roller 14k and the rotation axis of the connecting member 21k, or the connecting line passes through the separation force receiving part 98. The separation force receiving part 98 is positioned closer to the developing roller 14k than the locking part 96 and the pressing part 97. Specifically, the separation force receiving part 98 protrudes from the second sidewall 12k along the length of the developing cartridge 10k and passes through a through hole provided in the bearing member 100, wherein the bearing member 100 is mounted on the second sidewall 12k of the cartridge body 1k.
[0288] A sealing assembly is also provided between the container body 1k of the developing cartridge 10k and the developing roller 14k, the toner feeding roller, and the toner discharge blade 15k to prevent toner leakage from the gaps between them. Specifically, in this embodiment, the sealing assembly includes a first sealing component 93, a second sealing component 94, and a third sealing component 95, wherein the first sealing component 93 is disposed at both ends of the opening of the container body 1k along its length to seal the gap between the developing roller 14k and the container body 1k. Specifically, the first sealing component 93 may be felt.
[0289] The second sealing component 94 is elongated and positioned between the powder dispensing blade 15k and the cartridge body 1k, behind the opening 100k, to seal the gap between the powder dispensing blade 15k and the cartridge body 1k. The second sealing component 94 can be a sponge. The third sealing component 95 is positioned between the developing roller 14k and the cartridge body 1k, in front of the opening 100k, to seal the gap between the developing roller 14k and the rear side of the opening. The third sealing component 95 can be an elastic scraper or a sheet-like object.
[0290] The connection between the first sealing component 93 and the second sealing component 94, as well as between the first sealing component 93 and the third sealing component 95, can be an interference fit or filled with glue. The first sealing component 93, the second sealing component 94, and the third sealing component 95 are connected to form an annular sealing body, which surrounds the opening 100k.
[0291] The developing cartridge also has a stirring component inside the powder compartment. The stirring component includes a shaft 107k and a stirring part 108k extending outward from the shaft 107k. A recess 106k is provided on the top of the powder compartment. The recess 106k can prevent the stirring part 108k from interfering with the side wall of the powder compartment during rotation.
[0292] In some embodiments, a support member 99 is also provided between the third sealing member 95 and the housing 1k. The support member 99 is elongated and supports the third sealing member 95, allowing the third sealing member 95 to tilt at a certain angle.
[0293] In some embodiments, the separation force receiving unit 98 and the bearing component are conductive, and the separation force receiving unit 98 receives power from the imaging device and transmits it to components such as the developing roller 14k through the bearing component.
[0294] In the various embodiments and variations thereof of this application, the direction of movement of the detected component can be simply changed as needed, and the position of the detected component can be flexibly designed, which greatly improves the flexibility of the developing cartridge design; at the same time, by adjusting the position of the detected component, it is beneficial to the miniaturization of the developing cartridge.
[0295] In the various embodiments and variations thereof of this application, the component being tested is driven by a transmission component, at least a portion of which moves along the length of the housing to drive the component being tested. This eliminates the need to transmit the force driving the component through the rotation axis of the stirring component, thus not only eliminating the risk of deformation or even breakage of the stirring component's rotation axis but also solving the problem of delayed force transmission caused by deformation of the stirring component's rotation axis, thereby improving detection accuracy.
[0296] Finally, it should be noted that unless there are contradictory or mutually exclusive situations, the different embodiments and their variations disclosed above can be referenced, consulted or combined with each other, and the technical features of the different embodiments and their variations can also be combined and / or substituted with each other.

In order to facilitate the distinction between different components, this invention discloses terms such as "first" and "second". The terms "first" and "second" are not to be understood as limiting their quantity.
