DETAILED DESCRIPTION
[0050] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the various embodiments described below are not isolated from each other, and those skilled in the art can combine the structures of the following embodiments according to design requirements.
[0051] Example 1
[0052]
Overall structure of the developer cartridge
[0053] like Figure 1A-1D 、 Figure 2 、 Figure 3 、 Figure 4A and Figure 4B As shown, the developer box 1 includes a shell 2 forming a developer chamber 10 and a rotating member 3 rotatably mounted in the shell 2. The rotating member 3 can be, for example, a developing member 31 for conveying the developer outward, or a powder feeding member 32 arranged adjacent to the developing member 31 and conveying the developer to the developing member 31, or a stirring member 33 located in the developer chamber 10. The stirring member 33 stirs the developer in the developer chamber 10, which can prevent the developer from clumping on the one hand and convey the developer toward the powder feeding member 32 on the other hand. The developer box also includes a handle 23 connected to the shell 2, and the developing member 31 and the handle 23 are respectively located at both ends of the shell 2 along the installation direction.
[0054] The developing member 31 rotates about a first axis L1, and the housing 2 extends along a first direction parallel to the first axis L1. The developing cartridge 1 further has a second direction intersecting the first direction and a third direction intersecting both the first and second directions. Preferably, the first, second, and third directions are mutually perpendicular. One end 51 of the first direction points to the left of the developing cartridge, the other end 52 of the first direction points to the right of the developing cartridge, one end 53 of the second direction points to the front of the developing cartridge, and the developing member 31 is located in the front of the developing cartridge. The other end 54 of the second direction points to the rear of the developing cartridge, and the side opposite to the side where the developing member 31 is located is the rear of the developing cartridge. One end 55 of the third direction points upward of the developing cartridge, and the other end 56 of the third direction points downward of the developing cartridge.
[0055] Hereinafter, the left end of the developer cartridge is referred to as the driving end, and the right end is referred to as the conductive end. The detected member 9 in the device is disposed to the right of the developer cartridge, and thus the right end of the developer cartridge may also be referred to as the detecting end. The developer cartridge 1 further includes a detecting device 6 having a portion located at the driving end, another portion located at the detecting end, and a portion located between the driving end and the detecting end. The driving force transmission assembly 4 is configured to transmit the driving force received by the driving force receiving member 41 disposed at the driving end to the rotating member 3 and the detecting device 6.
[0056] The housing 2 has a left surface 21 facing left, a right surface 22 facing right, and a left end cover 27 and a right end cover 28 respectively combined with the housing 2, wherein the left end cover 27 is opposite to the left surface 21, and the right end cover 28 is opposite to the right surface 22, a portion of the driving force receiving member 41 is exposed outward from the left end cover, and a portion of the detection device 6 is exposed outward from the right end cover 28. Figure 1B As shown, the right end cover 28 has an exposure port 281, the size of which is larger than the size of the component of the detection device 6 located at the detection end (the functional component 63 described below); further, the developing box 1 also includes a developer regulating member 29 fixedly mounted on the shell 2, a conductive member 26 combined with the shell 2, and a chip assembly 11 mounted on one of the shell 2, the left end cover 27 and the right end cover 28. The chip assembly 11 can be a chip that is simultaneously provided with a substrate, electrical contacts and a storage part, or it can be a movable part having a substrate, electrical contacts, a storage part and a movable part that can be movably connected to the electrical contacts. The conductive member 26 is located at the detection end and is used to receive power from the device to supply to the developing member 31.
[0057] When the developing box 1 is working, the developing member 31 needs to be opposite to the photosensitive member outside the developing box so that the developer on the surface of the developing member 31 can reach the surface of the photosensitive member to realize development. For this purpose, it is more advantageous for the developing box 1 to be pushed toward the photosensitive member. Figure 1C and Figure 2As shown, the developing box 1 also includes a first forced pushing portion 2b1 and a second forced pushing portion 2b2 arranged at the rear of the developing box, wherein the first forced pushing portion 2b1 is located on the left side of the shell body 2, and the second forced pushing portion 2b2 is located on the right side of the shell body 2. Specifically, the first forced pushing portion 2b1 is formed to protrude to the left from the left direction of the shell body 2, and the second forced pushing portion 2b2 protrudes to the left from the right end cover 28. That is to say, along the first direction, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 both protrude in the same direction. Therefore, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 can also both protrude to the right. This structure is conducive to the miniaturization of the developing box 1.
[0058] [Right end cap]
[0059] In the second direction, the right end cap 28 is located behind the conductive member 26. A portion 282 of the right end cap 28 forms a second forced-pushing portion 2b2, and a portion of the active component is exposed through the exposed opening 281. When viewed in the first direction, the right end cap 28 does not overlap with the powder filling port 2a3 located at the detection end. When the developer in the developer cartridge is depleted, the user can refill the developer cartridge without removing the right end cap 28. In the third direction, the powder filling port 2a3 is located below the active component 63. With the protruding active component, when the user refills the developer cartridge, there is no interference with the active component 63. The active component 63 and the powder filling port 2a3 are both visible to the user, significantly reducing the risk of damage to the active component 63. In the first direction, the powder filling port 2a3 is located between the second forced-pushing portion 2b2 / 282 and the conductive member 26.
[0060] [Paper Guide]
[0061] When the developing box 1 is working, the imaging medium (such as printing paper) will pass through the developing box along the second direction from the bottom of the developing box 1 along the third direction. In order to keep the moving path of the imaging medium stable, the developing box 1 further includes a paper guide 2d provided under the shell 2. Figure 1C As shown, the paper guide 2d has a continuous surface extending basically along the first direction and the second direction. Preferably, the surface of the paper guide 2d is a smooth surface. More preferably, along the first direction, the surface of the paper guide 2d is a plane, and along the second direction, the surface of the paper guide 2d is a plurality of adjacent planes, and every two adjacent planes intersect at a line parallel to the first direction.
[0062] In practice, to prevent leakage of developer, Figure 1B As shown, along the first direction, the developing box 1 further includes a first sealing member 39 located at both longitudinal ends of the developing member 31, and Figure 3As shown, along the second direction, the developing box also includes a second seal 38 and a third seal 37, at least a portion of which is located in front of the developing member 13, the first seal 39 is preferably felt / sponge, which is used to seal at the longitudinal end of the developing member 31, the second seal 38 is preferably a sheet seal, which is used to contact and seal with the circumferential surface of the developing member 31, and the third seal 37 is preferably a sponge, which is used to contact and seal with the circumferential surface of the developing member 31.
[0063] Currently, the first seal 39, the second seal 38 and the third seal 37 are all combined with the housing 2 by sticking double-sided tape on one side. On the one hand, this method is not conducive to automated production, and the first seal 37 located at the two longitudinal ends of the developer will be subjected to a large pulling force, causing the first seal to be torn apart; on the other hand, this method has low installation accuracy, resulting in poor sealing effect. The utility model adopts the method of injecting adhesive on the side of the first seal 39 / second seal 38 facing the housing to achieve precise combination of the first seal 39 / second seal 38 and the housing 2. Figure 1C As shown, two injection ports 2e are further provided below the housing 2. Each injection port 2e is in communication with at least one of the first seal 39 and the second seal 38. Thus, the adhesive injected through the injection port 2e can smoothly reach the side of the first seal 39 and / or the second seal 38 facing the housing 2. Injecting the adhesive through the injection port 2e not only increases the bonding strength between the seals and the housing 2, but also effectively fills the gaps between the first seal 39, the second seal 38, and the third seal 37, as well as the gaps between each of the seals and the housing 2. Furthermore, injecting the adhesive through the injection port 2e allows for automated production of the developer cartridge 1. Preferably, along the first direction, the paper guide 2e is located between the two injection ports 2e to prevent the paper guide 2d from blocking the injection port 2e. Furthermore, along the first direction, the paper guide 2e is located between the conductive member 26 and the chip assembly 11 to prevent the chip assembly 11 from being affected by the conductive member 26.
[0064]
Drive force transmission components
[0065] The driving force transmission assembly 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43 and a stirring member driving member 44. When the stirring member driving member 44 is provided, the driving force transmission assembly 4 further includes an idler wheel 45 located between the driving force receiving member 41 and the detection device 6. The driving force receiving member 41 transmits the driving force to the stirring member driving member 44 through the idler wheel 45, and then the stirring member driving member 44 transmits the driving force to the detection device 6. In some embodiments, the driving force delivered to the detection device 6 can also come directly from any one of the driving force receiving member 41, the developing member driving member 42, the powder feeding member driving member 43 and the idler wheel 45. It is feasible that the stirring member 33 can be configured to rotate around an axis parallel to the first direction, or can be configured to reciprocate in a direction substantially parallel to the second direction. The driving force transmission method between the various driving members can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving member is configured as a gear.
[0066] The driving force receiving member 41 rotates around a second axis L2 parallel to the first direction, and the detected member 9 is configured as a rod that can rotate around a third axis L3 parallel to the first direction, including a rotating part 93 and a first rod 91 and a second rod 92 connected to the rotating part 93, wherein the second rod 92 is used to interact with the detection device 6, and the first rod 91 is used to be detected by the equipment.
[0067]
Detection device
[0068] The detection device 6 includes a driving component 61 arranged at the driving end, an acting component 63 arranged at the detection end, and a transmission member 62 located between the driving component 61 and the acting component 63. After receiving the driving force, the driving component 61 drives the transmission member 62 to move in a direction that is not perpendicular to the first direction, thereby forcing the acting component 63 to interact with the detected member 9. Preferably, the movement direction of the transmission member 62 is parallel to the first direction. More preferably, the transmission member 62 reciprocates in a direction parallel to the first direction. In this way, the detection end of the developing box no longer needs to be provided with components such as gears and ratchets for transmitting driving force, or the number of components such as gears and ratchets for transmitting driving force is reduced. The structure of the detection end is simplified, and when the developing box is assembled, it is only necessary to focus on the assembly of the driving end.
[0069] Example 2
[0070] like Figure 5 、 Figure 6 、 Figure 7A 、 Figure 7B and Figure 8 As shown, based on the above embodiment, this embodiment focuses on describing the structure of the conductive member 26 and its relative position in the developer box.
[0071] like Figure 5 As shown, along the second direction (the installation and disassembly direction of the developing box 1), the imaging device is provided with a first power output member 101 and a second power output member 102 spaced apart from each other. In the existing developing box, the first power output member 101 is used to supply power to the powder feeding member 32, and the second power output member 102 is used to supply power to the developing member 31. In the forward direction (the front 53 of the developing box), the second power output member 102 is located downstream of the first power output member 101.
[0072] In order to enable the developing cartridge 1 to stably receive power, this embodiment adopts a method in which the first power output component 101 supplies power to the developing component 31 and the powder feeding component 32 simultaneously. As shown in the figure, the conductive member 26 includes a main body 26a and a power input portion 26b, a developing member power supply portion 26c and a powder feeding member power supply portion 26d arranged on the main body 26a. The conductive member 26 is fixedly connected to the shell 2. In practice, the conductive member 26 can be fixedly connected to the shell 2 through at least any part thereof, for example, the main body 26a is fixedly connected to the shell 2, or the power input portion 26b is fixedly connected to the shell 2, or the developing member power supply portion 26c is fixedly connected to the shell 2, or the powder feeding member power supply portion 26d is fixedly connected to the shell 2; the power input portion 26b is used to electrically connect to the first power output member 101 to receive power, the developing member power supply portion 26c is used to supply the power received by the power input portion 26b to the developing member 31, and the powder feeding member power supply portion 26d is used to supply the power received by the power input portion 26b to the powder feeding member 32.
[0073] In some embodiments, the conductive member 26 is integrally formed of a conductive material. For example, the conductive member 26 is integrally formed by injection molding of a conductive plastic, or integrally formed by pressing a conductive metal sheet.
[0074] In some embodiments, the conductive member 26 is formed separately, and the power input portion 26b, the developing member power supply portion 26c and the powder feeding member power supply portion 26d are made of the aforementioned conductive material, and the power input portion 26b is electrically connected to the developing member power supply portion 26c and the powder feeding member power supply portion 26d at the same time through a conductive connector. In this way, the power received by the power input portion 26b can be simultaneously supplied to the developing member power supply portion 26c and the powder feeding member power supply portion 26d, and then supplied to the developing member 31 and the powder feeding member 32 by the developing member power supply portion 26c and the powder feeding member power supply portion 26d respectively; preferably, the main body 26a is made of conductive material, thereby, the installation of the conductive connector can be omitted, and the poor conductivity defects between the components of the conductive member 26 caused by assembly errors or material deformation and other factors can be avoided.
[0075] like Figure 6As shown, the developing part power supply portion 26c supplies power to the developing part 31 by being electrically connected to the developing part shaft 311 of the developing part 31, and the powder feeding part power supply portion 26d supplies power to the powder feeding part 32 by being electrically connected to the powder feeding part shaft 321 of the powder feeding part 32. The electrical connection method can be direct contact or indirect contact, and can be contact with the circumferential surface of the developing part shaft 311 / powder feeding part shaft 321, or can be contact with the longitudinal end of the developing part shaft 311 / powder feeding part shaft 321.
[0076] like Figure 7A As shown, when the developer cartridge 1 reaches the predetermined installation position of the imaging device, along the first direction, the first power output member 101 contacts the conductive member 26 / power input portion 26b at point D, but the second power output member 102 is not electrically connected to the conductive member 26. Along the first direction, the developer power supply portion 26c has a first exposed surface 26c1 facing the right 52. Preferably, the first exposed surface 26c1 is arranged to be inclined relative to the second direction, and along the second direction, the first exposed surface 26c1 gradually moves away from the housing 2 from the front to the rear. This design can make it easier to install the developer cartridge 1 in the imaging device.
[0077] like Figure 8 As shown, along the first direction, the power input portion 26b also has a second exposed surface 26b1 facing the right 52, and the second exposed surface 26b1 is set to a plane and is used to contact the first power output member 101 at point D. As a deformation mode of the conductive member 26, the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear. Similarly, this design can also make it easier for the developer box 1 to be installed on the imaging device, and can prevent the first power output member 101 and the conductive member 26 from interfering with each other and causing damage to both.
[0078] As described above, the action component 63 for moving the detected member 9 in the imaging device is exposed toward the detection end. The action component 63 can move the detected member 9 by rotation or translation, and the transmission member 62 for driving the action component 63 can also move by rotation or translation.
[0079] like Figure 7BAs shown, when the developing box 1 is observed along the first direction, a straight line N is drawn parallel to the second direction. Along the third direction, the rotation axis L1 of the developing member 31, the contact point D and the free end of the acting component 63 are projected on the straight line N at points T1, T2 and T3 respectively. Along the second direction, the distance between point T1 and point T2 is s1, and the distance between point T2 and point T3 is s3, s1>s3, that is, the contact point D is closer to the free end of the acting component 63, so that the influence of the vibration of the developing member 31 on the contact point D is reduced, that is, the first power output member 101 can stably output power to the power input part 26b.
[0080] It should be noted that the free end of the action component 63 refers to the portion of the action component 63 used to move the detected component 9 to complete the detection.
[0081] When the transmission member 62 drives the acting component 63 in a rotational manner, the rotation axis L6 of the transmission member 62 intersects the straight line N at point T4. Along the second direction, the distance between point T2 and point T4 is s2, s1>s2, that is, the contact point D is closer to the free end of the acting component 63, so that the influence of the vibration of the developing member 31 on the contact point D is reduced; when the transmission member 62 drives the acting component 63 in a translational manner, the point T4 is the projection of the midpoint of the transmission member 62 in the second direction dimension on the straight line N.
[0082] During the operation of the developing box, compared with the vibration caused by the interaction force between the developing member 31 and the photosensitive drum, the transmission member 62 and the acting component 63 ultimately only need to move the detected member 9, so that the vibration that may be generated by the transmission member 62 and the acting component 63 is smaller. Along the second direction, the contact point D is closer to the acting component 63 / transmission member 62, which is more conducive to ensuring that the first power output member 101 outputs power stably to the power input part 26b.
[0083] Therefore, this embodiment can achieve the following beneficial effects:
[0084] 1. Along the second direction, compared with the distance between the contact point D between the first power output member 101 and the conductive member 26 and the acting component 63 / transmission member 62, the distance between the contact point D between the first power output member 101 and the conductive member 26 and the rotation axis L1 of the developing member 31 is larger, which is beneficial to reducing the impact of the vibration of the developing member 31, making the electrical connection between the first power output member 101 and the conductive member 26 / power input part 26b more stable.
[0085] 2. As described above, the developing member 31 transports the developer toward the photosensitive drum. During this process, a small amount of developer will float away from the developing member 31 and the photosensitive drum. It can be seen that in point 1, the setting away from the developing member 31 can also reduce the risk of the developer floating onto the power input part 26b, thereby reducing the impact of the developer on the electrical connection between the first power output member 101 and the conductive member 26 / power input part 26b, ensuring that the conductive member 26 / power input part 26b stably receives power.
[0086] 3. Along the first direction, the conductive member 26 is arranged at the detection end rather than the driving end. When the developing box is working, the vibration generated by the driving force transmission component 4 at the driving end has less influence on the electrical connection between the first power output member 101 and the conductive member 26.
[0087] 4. Based on point 3, the detection end is not provided with a transmission gear, so that the first power output element 101 and the conductive element 26 can be electrically connected more stably.
[0088] 5. Such as Figure 7B As shown, when observed along the first direction, the second power output member 102 is located within the projection range of the driving force receiving member 41 at the detection end, while the first power output member 101 is located outside the projection range. It can be seen that the driving force receiving member 41 has a smaller impact on the electrical connection between the first power output member 101 and the power input member 26 when working.
[0089] 6. As described above, the powder feeding member 32 is used to supply the developer to the developing member 31. Generally, the voltage applied to the powder feeding member 32 is higher than the voltage applied to the developing member 31, that is, the voltage output by the first power output member 101 is higher than the voltage output by the second power output member 102. When the conductive member 26 is used to receive the power output by the first power output member 101, the voltage required by the powder feeding member 32 can be guaranteed first. Even if there is impedance in the main body 26a or the conductive connecting member, the voltage delivered to the developing member 31 can also meet the development requirements of the developing member 31.
[0090] Accordingly, a voltage reducing element may be provided between the power input portion 26 b and the developing device power supply portion 26 c to ensure that the developing device 31 can receive an appropriate voltage.
[0091] On the contrary, when the conductive member 26 is used to receive the power output by the second power output member 102, since the voltage originally output by the second power output member 102 is lower than the voltage required by the powder feeding member 32, and the impedance of the main body 26a or the conductive connecting member is added, the voltage received by the powder feeding member 32 will be even lower, which will be detrimental to the normal operation of the powder feeding member 32; in this way, although the powder feeding member 32 can obtain a suitable voltage by setting a boosting element in the conductive member, it is obvious that the bucking element has lower cost and is easier to install.
[0092] Example 3
[0093] like Figure 9 As shown, for ease of understanding and description, the same reference numerals are used for the same components in this embodiment as in the above embodiment.
[0094] The conductive part 26 still includes a main body 26a and a power input part 26b and a developing part power supply part 26c arranged on the main body 26a. The conductive part 26 is fixedly connected to the shell 2. The power input part 26b is used to electrically connect to the first power output part 101 to receive power. The developing part power supply part 26c is used to supply the power received by the power input part 26b to the developing part 31. Specifically, the developing part power supply part 26c is electrically connected to the developing part shaft 311 to supply power to the developing part 31. In this embodiment, the powder feeding part 32 is not directly supplied with power, that is, the powder feeding part 32 is not electrically in contact with the conductive part 26. Therefore, the conductive part 26 does not need to be provided with the above-mentioned powder feeding part power supply part 26d for electrically connecting to the powder feeding part shaft 321. Finally, the structure of the conductive part 26 is simplified.
[0095] Further, continue as Figure 9 As shown, the powder feeding member 32 is located inside the shell 2, and along the left and right directions, the powder feeding member 32 does not exceed the right surface 22 of the shell 2, so that the conductive member 26 will not be electrically connected to the powder feeding member 32 / powder feeding member shaft 321; in some embodiments, the powder feeding member 32 can also be configured to pass through the right surface 22, but the conductive member 26 is still not electrically connected to the powder feeding member 32 / powder feeding member shaft 321.
[0096] As described above, since the voltage output by the first power output element 101 is higher than the voltage output by the second power output element 102, when the conductive element 26 is used to receive power from the first power output element 101, even if the developing box 1 is in a harsh environment, the charging performance of the developer is reduced, but the developing element 31 can obtain a higher voltage, and a greater electric field force can be generated between the developing element 31 and the photosensitive drum. Therefore, the developer can smoothly reach the surface of the photosensitive drum from the surface of the developing element 31, and the deterioration of the development quality can be effectively suppressed.
[0097] Based on the inventive concept, when the voltage applied to the developing member 31 does not change, the charging performance of the developer can be improved by changing the physical and chemical characteristics of the developer, so that the developer can smoothly reach the surface of the photosensitive drum from the surface of the developing member 31.
[0098] Similar to the second embodiment, the power input portion 26b in this embodiment also has the second exposed surface 26b1, and the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear, which can also prevent the first power output component 101 and the conductive component 26 from interfering with each other and causing damage to both.
[0099] Example 4
[0100] like Figure 10 As shown, for ease of understanding and description, the same reference numerals are used for the same components in this embodiment as in the above embodiment.
[0101] The stirring member 33 is configured to reciprocate in a direction roughly parallel to the second direction. As shown in the figure, the stirring member 33 includes a frame 331 and a powder feeding plate 332 arranged on the frame 331. At the same time, the frame 331 is connected to the shell 2 through an elastic member 16. As the drive rod 89 rotates, the frame 331 is pushed by the thrust applied by the force-applying portion 893 (such as a cam) provided on the drive rod 89 and moves roughly in the second direction toward the direction away from the developing member 31 (the direction close to the handle 23). The elastic member 16 elastically deforms and accumulates elastic force. When the force-applying portion 893 no longer applies force to the frame 331, the elastic member 16 releases the elastic force and causes the frame 331 to move roughly in the second direction toward the direction close to the developing member 31 (the direction away from the handle 23). When the stirring member 33 collides with the drive rod 89, the powder feeding plate 332 will shake, and the developer located above the powder feeding plate 332 will fall. The powder feeding plate 332 transports the developer away from the developing member 31 toward the direction close to the developing member 31.
[0102] Furthermore, the developing box 1 also includes a buffer member 34 arranged on the stirring member 33. When the buffer member 34 moves in the direction close to the developing member 31 along with the stirring member 33, the noise generated when the buffer member 34 collides with the driving rod 89 can be reduced. Preferably, along the second direction, the buffer member 34 is opposite to the force-applying portion 893. In this way, when the force-applying portion 893 applies thrust to the stirring member 33, the noise of the collision between the force-applying portion 893 and the stirring member 33 can also be reduced. At the same time, the abnormal noise generated when the stirring member 33 shakes can also be reduced.
[0103] The buffer member 34 can be combined with the stirring member 33 by bonding, welding, snapping, etc. The buffer member 34 is preferably an elastic member. For example, at least a part of the buffer member 34 is configured as a sponge, silicone, a spring, etc.
[0104] like Figure 10As shown, more preferably, the buffer member 34 is combined with the stirring member 33 in a snap-fit manner, and the frame 331 is provided with a mounting portion 333, and at least a portion of the buffer member 34 is accommodated by the mounting portion 333. For example, a snap-fit groove 341 is provided on the buffer member 34, and correspondingly, a snap-fit protrusion 334 that cooperates with the snap-fit groove 341 is provided on the mounting portion 333. At the same time, the buffer surface 342 of the buffer member 34 faces the driving rod 89.
[0105] In addition, compared with the way that the buffer member 34 is pasted and installed on the stirring member 33, the way in which the engaging groove 341 and the engaging protrusion 334 cooperate can ensure that the buffer member 34 is installed more conveniently and stably, and the installation position of the buffer member 34 can be precisely controlled.
[0106] Example 5
[0107] like Figure 11 and Figure 12 As shown, in this embodiment, the conductive member 26 still includes a main body 26a and a power input portion 26b and a powder feeding member power supply portion 26d provided on the main body 26a. The conductive member 26 is fixedly connected to the housing 2. The power input portion 26b is used to be electrically connected to the first power output member 101 or the second power output member 102 to receive power. The powder feeding member power supply portion 26d is used to supply the power received by the power input portion 26b to the powder feeding member 32. Specifically, the powder feeding member power supply portion 26d is electrically connected to the powder feeding member shaft 321 to supply power to the powder feeding member 32. In this embodiment, the developing The developing member 31 is not directly supplied with electricity, that is, the developing member 31 does not have to be directly electrically connected / electrically contacted with the first power output member 101 or the second power output member 102, but is supplied with electricity by the powder feeding member 32. Therefore, the conductive member 26 does not have to be provided with the above-mentioned developing member power supply part 26c for electrically connecting to the developing member shaft 311. Finally, the structure of the conductive member 26 is simplified. In some embodiments, the developing member shaft 311 can also be made of non-conductive material. Even if a conductive component (such as the conductive member 26) is in contact with the developing member shaft 311, the developing member shaft 311 will not transfer electricity to the developing layer 312.
[0108] like Figure 11 As shown, the powder feeding member shaft 321 is exposed from the right surface 22 of the shell, and the developing member 31 is located inside the shell 2. Along the left and right directions, the developing member 31 does not exceed the right surface 22 of the shell 2. In this way, the conductive member 26 will not be electrically connected to the developing member 31 / developing member shaft 311; in some embodiments, the developing member 31 can also be configured to pass through the right surface 22, but the conductive member 26 is still not electrically connected to the developing member 31 / developing member shaft 311.
[0109] like Figure 3As shown, the developing member 31 further includes a developing layer 312, and the powder feeding member 32 further includes a powder feeding layer 322, wherein the developing layer 312 is further away from the developing member rotation axis L1 than the circumferential surface of the developing member shaft 311, and the powder feeding layer 322 is further away from the powder feeding member rotation axis L7 than the circumferential surface of the powder feeding member shaft 321, and the developing layer 312 and the powder feeding layer 322 are in contact with each other. Generally, the developing layer 312 and the powder feeding layer 322 are made of elastic material. In this embodiment, when the developing member 31 is not directly supplied with electricity, the powder feeding layer 322 and the developing layer 312 are preferably made of elastic conductive material, for example For example, the powder feeding layer 322 and the developing layer 312 are made of conductive sponge / rubber, etc., so that after the powder feeding part 32 is supplied with electricity, an electric field force will be formed between the surface of the powder feeding part 32 and the surface of the developing part 31, and the developer on the surface of the powder feeding part 32 can reach the surface of the developing part 31 from the surface of the powder feeding part 32 under the action of the electric field force. At the same time, the electricity supplied to the powder feeding part 32 will be transmitted to the developing layer 312 through the powder feeding layer 322, so that the developing part 31 is also supplied with electricity, and then the developer regulating part 29 in contact with the surface of the developing part 31 / developing layer 312 is also supplied with electricity.
[0110] Furthermore, when the powder feeding member 32 is supplied with electricity, the developer located on the surface of the powder feeding member 32 will also be charged, thereby forming an electric field force between the developer on the surface of the powder feeding member 32 and the surface of the developing member 31. Under the action of this electric field force, the developer can more easily reach the surface of the developing member 31 from the surface of the powder feeding member 32.
[0111] It can be seen that in this embodiment, not only the powder feeding layer 322 can serve as a component for supplying power to the developing member 31 , but the developer located between the developing member 31 and the powder feeding member 32 can also serve as a component for supplying power to the developing member 31 .
[0112] Based on the inventive concept of the embodiment of the utility model, the developing member 31 and the powder feeding member 32 can be any one of the following two specific structures:
[0113] In some embodiments, along the first direction, the developing member shaft 311 passes through the developing layer 312, and the powder feeding member shaft 321 passes through the powder feeding layer 322. At this time, the developing layer 312 covers at least a portion of the circumferential surface of the developing member shaft 311, and the powder feeding layer 322 covers at least a portion of the circumferential surface of the powder feeding member shaft 321.
[0114] In some embodiments, along the first direction, the developing member shaft 311 does not pass through the developing layer 312, and the powder feeding member shaft 321 does not pass through the powder feeding layer 322. At this time, the developing layer 312 covers a portion of the circumferential surface of the developing member shaft 311, or the developing layer 312 does not cover the circumferential surface of the developing member shaft 311, the developing member shaft 311 protrudes from the longitudinal end surface of the developing layer 312, and the powder feeding layer 322 covers a portion of the circumferential surface of the developing member shaft 321, or the powder feeding layer 322 does not cover the circumferential surface of the powder feeding member shaft 321, and the powder feeding member shaft 321 protrudes from the longitudinal end surface of the powder feeding layer 322.
[0115] In particular, when the power input part 26b is electrically connected to the first power output part 101, the developing part 31 will be able to receive a voltage higher than the predetermined voltage. Even if the processing box 1 is in a humid, high-temperature and high-pressure environment, the charge of the developer reaching the surface of the developing part 31 can be kept within a reasonable range. As a result, the deterioration of the development quality of the processing box 1 can be effectively suppressed.
[0116] Same as the above embodiment, Figure 12 As shown, the power input portion 26b has a second exposed surface 26b1 facing the right 52, and the second exposed surface 26b1 is formed as a plane for contacting the first power output member 101 / the second power output member 102 at point D. Preferably, the second exposed surface 26b1 is arranged to be inclined relative to the second direction, and along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear. Similarly, this design can also make it easier for the developer box 1 to be installed to the imaging device, and can prevent the first power output member 101 and the conductive member 26 from interfering with each other and causing damage to both.
[0117] Example 6
[0118] First refer to Figure 3 As shown, the developer regulating member 29 includes a fixed body 291 fixedly connected to the shell 2 and a regulating body 292 arranged on the fixed body 291, and the regulating body 292 is in contact with the developing layer 312. In some embodiments, the regulating body 292 and the developing layer 312 are both made of conductive materials. For this reason, it is possible to use the developer regulating member 29 to power the developing member 31. This scheme will be described in detail below.
[0119] like Figure 13 、 Figure 14 、 Figures 14A-14CAs shown, the conductive member 26 includes a main body 26a and a power input portion 26b and an adjusting member power supply portion 26e arranged on the main body 26a. The power input portion 26b is used to be electrically connected to the second power output member 102 to receive power. The developing member 31 and the powder feeding member 32 are not directly electrically connected to the conductive member 26, that is, the developing member 31 and the powder feeding member 32 are not in direct electrical contact with the conductive member 26.
[0120] Specifically, the regulating member power supply portion 26e is configured to be in direct electrical contact with at least one of the fixed body 291 and the regulating body 292, so that the power received by the power input portion 26b can be supplied to the developer regulating member 29 through the regulating member power supply portion 26e. Along the first direction, the regulating body 292 is in contact with the developing layer 312, so that the developing member 31 will receive power from the developer regulating member 29 through the developing layer 312 or the developer carried by the developing layer 312, and then the developing member 31 will transfer the power to the powder feeding member 32 in contact with it.
[0121] like Figure 14 As shown, the power input portion 26b also has the above-mentioned second exposed surface 26b1 inclined relative to the second direction, which will not be repeated here; it should be pointed out that the developing member 31 in this embodiment no longer receives power through the above-mentioned developing member shaft 311 and the conductive member 26, but receives power from the developer regulating member 29 through the developing layer 312. During the operation of the developing box 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between the two to become unstable.
[0122] At the same time, the developing member 31 / developing layer 311 receives electricity from the developer regulating member 29, and the position where the developing member regulating member 29 contacts the developing member 31 / developing layer 311 is away from the position where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can still receive electricity stably.
[0123] As described above, the conductive member 26 in this embodiment does not need to be provided with the above-mentioned developing member power supply portion 26c and the powder feeding member power supply portion 26d, so the structure of the conductive member 26 becomes simple.
[0124] In addition, compared with the conductive method in which the conductive member 26 contacts the end of the developing member shaft 311, in this embodiment, along the first direction, the regulating body 292 contacts the developing layer 312 / developing member 31, and the electrical contact surface of the developing layer 312 / developing member 31 is increased. Accordingly, the electrical connection stability of the developing member 31 is improved, and a uniform voltage can be obtained on the surface of the developing member 31 / developing layer 311.
[0125] Further, such as Figure 14AAs shown, along the first direction, the outer surface of the developing member 31 / developing layer 311 is formed with two oppositely arranged non-developing areas X1 and a developing area X2 located between the two non-developing areas X1 , and the regulating body 292 is in contact with at least the developing area X2 .
[0126] In order to obtain a more uniform voltage on the surface of the developing member 31 / developing layer 311, the developing member 31 also includes an electric power enhancement member 35 arranged on the developing member 31 / developing layer 311. The electric power enhancement member 35 is a conductor, and the electric power enhancement member 35 can extend both on the outer surface of the developing member 31 / developing layer 311 and in the developing layer 311.
[0127] Figure 14A A first type of power enhancement component 35A is shown, which extends non-linearly in the first direction. Specifically, the first type of power enhancement component 35A is configured to extend in a wave shape in the first direction. When the developer regulating component 29 and / or the powder feeding component 32 described below contacts the power enhancement component 35A, the power enhancement component 35A can apply voltage uniformly to the outer surface of the developing component 31 / developing layer 311.
[0128] When the developing member 31 is projected along the first direction, the power amplifying member 35 is a circle formed on the developing member 31 / developing layer 311 , and the developing member rotation axis L1 passes through the center of the circle.
[0129] Figure 14B A second type of power enhancement component 35B is shown, which extends linearly in a first direction. Multiple second type of power enhancement components 35B are arranged parallel to each other on the outer surface of the developing component 31 / developing layer 311. When the developer regulating component 29 and / or the powder feeding component 32 described below are in contact with the power enhancement component 35B, the power enhancement component 35B can apply voltage uniformly to the outer surface of the developing component 31 / developing layer 311.
[0130] When the developing member 31 is projected along the first direction, the power amplifying member 35 is a point formed on the developing member 31 / developing layer 311 .
[0131] Figure 14C A third type of power enhancement component 35C is shown, which extends in a mesh shape in a first direction. When the developer regulating component 29 and / or the powder feeding component 32 described below contacts the power enhancement component 35C, the power enhancement component 35C can apply voltage uniformly to the outer surface of the developing component 31 / developing layer 311.
[0132] When the developing member 31 is projected along the first direction, the power amplifying member 35 is a circle formed on the developing member 31 / developing layer 311 , and the developing member rotation axis L1 passes through the center of the circle.
[0133] In the first type of power enhancement component 35A and the third type of power enhancement component 35C, when the developing component 31 is projected along the first direction, the power enhancement component 35A / 35C can also be a section of an arc line formed on the developing component 31 / developing layer 311, that is, the projection of the power enhancement component 35A / 35C in the first direction is not a whole circle, and the developing component rotation axis L1 passes through the center of the circle where the arc line is located, but as long as the power enhancement component 35A / 35C can contact the developer regulating component 29 and / or the powder feeding component 32 described below, it is possible to achieve uniform application of voltage to the outer surface of the developing component 31 / developing layer 311.
[0134] Example 7
[0135] like Figure 15 and Figure 16 As shown, the difference from the sixth embodiment is that the developer regulating member 29 and the powder feeding member 32 in this embodiment are in electrical contact with the conductive member 26 at the same time. For example, the fixed body 291 / regulating body 292 is in direct electrical contact with the conductive member 26, and the powder feeding member shaft 322 is in direct electrical contact with the conductive member 26. Figure 15 As shown, the conductive part 26 includes a main body 26a and a power input part 26b, an adjusting part power supply part 26e and a powder feeding part power supply part 26d arranged on the main body 26a; the power input part 26b is electrically connected to the second power output part 102 to receive power, and the adjusting part power supply part 26e and the powder feeding part power supply part 26d supply power to the developer adjusting part 29 and the powder feeding part 32 respectively.
[0136] Along the first direction, the developer regulating member 29 contacts the developing layer 312, and at the same time, the powder feeding member 32 / powder feeding layer also contacts the developing layer 322 and the developing layer 312, so that at least one of the power received by the developer regulating member 29 and the power received by the powder feeding member 32 is supplied to the developing layer 312.
[0137] In this embodiment, the power input portion 26b also has the above-mentioned second exposed surface 26b1 inclined relative to the second direction, and the developing member 31 does not need to receive power through direct contact between the developing member shaft 311 and the conductive member 26, that is, the developing member 31 is not in direct electrical contact with the conductive member 26. During the operation of the developing box 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between the two to become unstable.
[0138] At the same time, the developing member 31 / developing layer 311 receives electricity from at least one of the developer regulating member 29 and the powder feeding member 32, and the position where the developing member regulating member 29 contacts the developing member 31 / developing layer 311 and the position where the powder feeding member 32 contacts the developing member 31 / developing layer 311 are both away from the position where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can stably receive electricity.
[0139] Example 8
[0140] like Figure 17 and Figure 18 As shown, unlike Example 6, the conductive member 26 in this embodiment is electrically connected to the first power output member 101 to receive power, and the developing member 31 and the powder feeding member 32 in this embodiment are not directly electrically connected to the conductive member 26, that is, the developing member 31 and the powder feeding member 32 are not in direct electrical contact with the conductive member 26, and the conductive member 26 is in direct electrical contact with the fixed body 291 / regulating body 292. In this way, the conductive member 26 will receive power and supply it to the developer regulating member 29. Similar to Example 6, the developer regulating member 29 then supplies power to the developing member 31 / developing layer 312, and finally the developing member 31 / developing layer 312 supplies power to the powder feeding member 32 / powder feeding layer 322.
[0141] Similarly, the power input portion 26b in this embodiment also has the above-mentioned second exposed surface 26b1 inclined relative to the second direction, and the developing member 31 does not have to receive power through direct contact between the developing member shaft 311 and the conductive member 26. During the operation of the developing box 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between the two to become unstable.
[0142] As in Example 6, the developing member 31 / developing layer 311 receives electricity from the developer regulating member 29, and the position where the developing member regulating member 29 contacts the developing member 31 / developing layer 311 is away from the position where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can still receive electricity stably.
[0143] Example 9
[0144] like Figure 19 and Figure 20As shown, different from Example 7, the conductive member 26 in this embodiment is electrically connected to the first power output member 101 to receive electricity, and the conductive member 26 directly transmits the received electricity to the developer regulating member 29 and the powder feeding member 32, and finally the developer regulating member 29 and / or the powder feeding member 32 supplies electricity to the developing layer 312 / developing member 31. For example, the fixed body 291 / regulating body 292 is in direct electrical contact with the conductive member 26, and the powder feeding member shaft 322 is in direct electrical contact with the conductive member 26. In this way, the developing member 31 does not have to receive electricity through direct contact with the conductive member 26 through the developing member shaft 311, that is, the developing member 31 is not in direct electrical contact with the conductive member 26. During the operation of the developing box 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between the two to become unstable.
[0145] Similar to the seventh embodiment, the developing member 31 / developing layer 311 receives electricity from at least one of the developer regulating member 29 and the powder feeding member 32, and the position where the developer regulating member 29 contacts the developing member 31 / developing layer 311 and the position where the powder feeding member 32 contacts the developing member 31 / developing layer 311 are both far away from the position where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can stably receive electricity.
[0146] Example 10
[0147] like Figure 21 As shown, this embodiment continues to provide a structure for supplying power to the rotating member 3, such as Figure 21 As shown, the conductive member 26 in this embodiment includes a developing member power input portion 26b2, a powder feeding member power input portion 26b3 and a power output portion 26e, wherein the developing member power input portion 26b2 is used to combine with the second power output member 102 to receive the power output by the second power output member 102, the powder feeding member power input portion 26b3 is used to combine with the first power output member 101 to receive the power output by the first power output member 101, and the power output portion 26e is used to simultaneously supply the power received by the developing member power input portion 26b2 and the power received by the powder feeding member power input portion 26b3 to any one of the developing member 31, the powder feeding member 32 and the developer regulating member 29, and when the power output by the power output portion 26e is supplied to the powder feeding member 32 or the developer regulating member 29, the powder feeding member 32 or the developer regulating member 29 then supplies power to the developing member 31.
[0148] In a deformable manner, the power output portion 26e can also be used to simultaneously supply the power received by the developing part power input portion 26b2 and the power received by the powder feeding part power input portion 26b3 to at least one of the developing part 31, the powder feeding part 32 and the developer regulating part 29.
[0149] This power supply method has the following beneficial effects:
[0150] 1. In this solution, the power output by the first power output element 101 and the power output by the second power output element 102 are simultaneously received by the conductive element 26 and output by the conductive element 26 to any one of the developing element 31, the powder feeding element 32 and the developer regulating element 29. Compared with the solution in which the first power output element 101 or the second power output element 102 is in contact with the conductive element 26, the current output by the conductive element 26 in this solution is larger. As a result, the power obtained by the developing element 31, the powder feeding element 32 or the developer regulating element 29 is also greater, which can ensure that the development quality remains good.
[0151] 2. Compared with the conductive member 26 outputting power to the developing member 31, when the conductive member 26 outputs power to the developer regulating member 29 or the powder feeding member 32, along the second direction, the power output portion 26e is further away from the contact position between the developing member 31 and the photosensitive member. Therefore, during the operation of the developing box 1, the vibration generated between the developing member 31 and the photosensitive member has less influence on the power output portion 26e.
[0152] 3. Compared with the conductive member 26 directly contacting the developing member shaft 311, when the conductive member 26 outputs electricity to the developer regulating member 29 or the powder feeding member 32, since the developing member 32 and the developer regulating member 29 are both in direct contact with the outer surface of the developing member 31, the electricity output by the powder feeding member 32 or the electricity output by the developer regulating member 29 can be directly transmitted to the developing member 31, and the power loss is smaller.
[0153] The developing box 1 further includes a right bracket 2g for supporting the developing member 31. The conductive member 26 can be formed integrally with the right bracket 2g or separately. Figure 21 The structure in which the conductive member 26 and the right bracket 2g are formed separately is shown.
[0154] Example 11
[0155] like Figure 22-24B As shown, based on the above embodiment, this embodiment further introduces the chip component 11, which is the same as the embodiment 1. Figure 22 and Figure 23 As shown, the chip assembly 11 in this embodiment also includes a conductor A92, a pushing member A93, a movable member A94 and a chip 7, wherein the working process of each component in the chip assembly 11 is the same as that in the first embodiment and will not be repeated here. The conductor A92, the pushing member A93 and the movable member A94 form at least a part of the chip connection assembly. Preferably, the chip assembly 11 also includes a pressing member A98 for preventing the conductor A92 from falling off.
[0156] The difference from the first embodiment is that the chip assembly 11 is arranged on the housing 2. Figure 22 As shown, the developing box 1 also includes a support member 2a arranged on the shell 2, and the chip assembly 11 is supported by the support member 2a. Specifically, at least the movable member A94 is supported by the support member 2a, and the chip 7 can move with the movable member A94; the conductor A92 has a first contact portion A921 for contacting with a contact pin in the device and a second contact portion A922 for contacting with the chip electrical contact 72. Hereinafter, the chip electrical contact 72 is arranged on a surface of the substrate 71.
[0157] Figure 24A and Figure 24B The developing cartridge 1 is in a state of being mounted on the drum frame or being mounted on the device. At this time, the moving direction of the movable member A94 is neither perpendicular nor parallel to the surface of the substrate 71 on which the chip electrical contacts 72 are provided, and the chip 7 can move with the movable member A94. Preferably, the extending direction of the surface is parallel to the moving direction of the movable member A94. Therefore, when the movable member A94 moves from Figure 24A The position shown is toward Figure 24B During the position movement shown, the surface may be pressed against the second contact portion A922 , thereby enabling the second contact portion A922 to form a stable electrical contact with the chip electrical contact 72 .
[0158] Example 12
[0159] like Figure 25 and Figure 26 As shown, similar to the eleventh embodiment, the chip assembly 11 in this embodiment is also arranged on the housing 2, but the position of the chip 7 in the movable member A94 in this embodiment is different from that in the eleventh embodiment, as shown in FIG. Figure 26 As described, the extension direction of the surface of the substrate 71 on which the chip electrical contact 72 is provided is not parallel to the movement direction of the movable part A94. Along the third direction, the surface is located below the second contact portion A922. In this way, when the chip 7 moves upward with the movable part A94, the second contact portion A922 and the chip electrical contact 72 can form a stable electrical contact.
[0160] In summary, the power input portion 26b in the conductive member 26 can be electrically connected to one of the first power output member 101 and the second power output member 102 to receive power, and then output it to at least one of the developing member 31, the powder feeding member 32 and the developer regulating member 29 through the power output portion (at least one of the developing member power supply portion 26c, the powder feeding member power supply portion 26d and the regulating member power supply portion 26e). Preferably, the conductive member 26 is not provided with a developing member power supply portion 26c for direct electrical connection to the developing member shaft 311, that is, the developing member 31 is not in direct electrical contact with the conductive member 26, and the developing member 31 is located radially outside the developing member shaft 311. The developing layer 312 on the side receives electricity from at least one of the powder feeding member 32 and the developer regulating member 29. During the operation of the developing box 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between the two to become unstable; at the same time, the position where the developing member regulating member 29 contacts the developing member 31 / developing layer 311 and the position where the powder feeding member 32 contacts the developing member 31 / developing layer 311 are both away from the position where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can stably receive electricity.
