[0003] The toner cartridge is detachably installed into a developing cartridge equipped with a developing roller. The toner cartridge holds the toner, and the developing roller carries the toner and supplies it to a photosensitive drum positioned opposite the developing roller, thus developing the electrostatic latent image formed on the surface of the photosensitive drum. To meet the need for equipment miniaturization, the capacity of existing toner cartridges is generally small. With this configuration, the frequency of toner cartridge replacement or toner replenishment increases, thereby increasing the user's operating costs and affecting the user experience. Utility Model Content

[0004] This utility model provides a toner cartridge, a developing cartridge having the toner cartridge, and a processing cartridge having the developing cartridge, to solve at least one of the above-mentioned technical problems. The specific technical solution is as follows:

[0005] Toner cartridge, used to hold toner, includes:

[0006] The main housing has a toner cavity for containing toner.

[0007] The powder outlet is located in the main housing and communicates with the toner chamber. The toner is transported to the outside of the toner cartridge through the powder outlet.

[0008] A toner conveyor for stirring and conveying toner, and is rotatably disposed in the toner chamber about a third rotation axis parallel to the left and right directions;

[0009] A drive force receiver is used to receive drive force from outside the toner cartridge, which is used to drive the toner conveyor to rotate.

[0010] The direction from the end of the toner cartridge with the drive force receiver to the end without the drive force receiver is the left-to-right direction. The direction intersecting the left-right direction is the front-back direction. The toner outlet is exposed forward, and the direction intersecting both the left-right and front-back directions is the up-down direction. The toner cartridge has at least four corners formed by a cross-section perpendicular to the left-right direction. In the up-down direction, two of the corners are above the other two corners. At least one of the two upper corners is a right angle, and the two lower corners are rounded chamfers.

[0011] In the front-back direction, the third rotation axis is closer to the toner outlet than the center line of the toner cavity in the front-back direction. The center line of the cavity is parallel to the left-right direction and passes through the midpoint of the length of the toner cavity in the front-back direction.

[0012] The toner cartridge also includes a sealing assembly that can move between a sealed position and an unsealed position. The sealing assembly includes an actuating element, a sealing element, and a connecting element for connecting the actuating element and the sealing element. The sealing element or toner outlet is located in front of the actuating element. The sealing element includes a connecting port and a sealing part arranged in the left-right direction. The connecting port is used to communicate with the toner outlet, and the sealing part is used to seal the toner outlet.

[0013] The actuating element is configured to move in the left and right direction, and drives the sealing element to move in the left and right direction through the connecting element. In the sealing position, the powder outlet is sealed by the sealing part, and in the unsealed position, at least a part of the powder outlet is connected to the connecting port.

[0014] The main housing also includes a first mounting space and a second mounting space that are spaced apart and opposite to each other in the vertical direction. In the vertical direction, the first mounting space, the toner chamber and the second mounting space are arranged in a downward direction, and at least a portion of the connector is located in the first mounting space and the second mounting space.

[0015] The actuator includes a base plate and a pushing part disposed on the base plate. Under the action of external force, the pushing part and the base plate move together in the left-right direction, and the connecting part is connected to the base plate. In the front-back direction, a clearance space is formed between the base plate and the main housing. The clearance space is connected to the second mounting space and is used to avoid a part of the actuator.

[0016] The main housing is also provided with at least one first mating part. The actuating member is installed onto the main housing in a direction from back to front. During the installation of the actuating member, the base plate and the first mating part are pressed against each other.

[0017] The toner cartridge also includes a secondary housing, an exposure port, and a gear mounting cavity formed inside the secondary housing.

The opening communicates with the gear mounting cavity and is spaced apart from the exposure port in the front-rear direction.

[0018] The toner cartridge is supplied to the developing cartridge through the toner outlet. The developing cartridge is provided with a toner inlet for receiving the toner supplied by the toner cartridge and a switch for controlling the opening or closing of the toner inlet. The sub-housing is also provided with a triggering part for triggering the switch. When the toner cartridge is installed in the developing cartridge, the triggering part triggers the switch, causing the switch to open.

[0019] The toner cartridge is detachably installed into the developing cartridge. The toner in the toner cartridge is delivered to the developing cartridge through the toner outlet. The developing cartridge includes a developing housing and a developing roller rotatably disposed on the developing housing. The developing roller is used to carry the toner.

[0020] The processing cartridge includes a drum cartridge and a developing cartridge connected together. The drum cartridge includes a drum housing and a photosensitive drum rotatably disposed in the drum housing. The developing roller and the photosensitive drum are disposed opposite each other. The developing roller is used to deliver toner to the photosensitive drum, so that the electrostatic latent image formed on the surface of the photosensitive drum is developed.

[0021] Compared with the prior art, the toner cartridge, the developing cartridge with the toner cartridge, and the processing cartridge with the developing cartridge provided by this utility model have at least four corners formed by the cross-section perpendicular to the left and right direction in the toner cartridge. In the up and down direction, two of the corners are above the other two corners. At least one of the two upper corners is a right angle, and the two lower corners are rounded. With this configuration, the capacity of the toner chamber is increased, and users no longer need to frequently replace the toner cartridge or replenish the toner, thus improving the user experience.

[0030] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] The processing cartridge is detachably mounted to an electrophotographic imaging device. The processing cartridge includes a developing cartridge and a drum cartridge connected together. The developing cartridge includes a developing housing and a developing roller rotatably disposed on the developing housing. The developing roller rotates about a first rotation axis. The drum cartridge includes a drum housing and a photosensitive drum rotatably disposed in the drum housing. The photosensitive drum rotates about a second rotation axis, which is parallel to the first rotation axis. The developing roller and the photosensitive drum are arranged opposite to each other. The processing cartridge also includes a toner cartridge 100 for containing toner. The toner cartridge 100 is detachably mounted to the developing cartridge. The toner in the toner cartridge 100 is conveyed to the developing cartridge or the developing roller. The developing roller carries the toner and conveys the toner to the photosensitive drum, thereby developing the electrostatic latent image formed on the surface of the photosensitive drum.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the toner cartridge 100 includes a main housing 10, a toner chamber 20, a toner conveyor 30, a driving force receiver 40, and a toner outlet 50. The toner chamber 20 is formed in the main housing 10 and is used to contain toner. The toner conveyor 30 is rotatably disposed in the toner chamber 20 and is used to convey and stir the toner. The toner conveyor 30 rotates about a third rotation axis L. The driving force receiver 40 is used to receive a driving force from outside the toner cartridge 100. The driving force is used to drive the toner conveyor 30 to rotate. The toner conveyor 30 includes a rotating shaft 31 and a conveying blade 32 disposed on the rotating shaft 31. The conveying blade 32 is used to convey and stir the toner. The rotating shaft 31 is used to receive the driving force from the driving force receiver 40 to drive the conveying blade 32 to rotate together with the rotating shaft 31.

[0033] For ease of description and understanding below, the following definitions apply: the direction parallel to the third rotation axis L is the left-right direction; the direction from one end of the toner cartridge 100 where the driving force receiver 40 is located to the end where the driving force receiver 40 is not located is the left-to-right direction, that is, the driving force receiver 40 is located at the left end of the toner cartridge 100; the toner outlet 50 is located on the main housing 10 and communicates with the toner chamber 20, through which toner is transported to the developing cartridge; the direction intersecting the left-right direction is the front-back direction; the toner outlet 50 is exposed forward; the direction intersecting both the left-right and front-back directions is the up-down direction, preferably the left-right, front-back, and up-down directions; when the toner cartridge 100 is installed in the developing cartridge, the above directions still apply to the toner cartridge 100.

[0034] In some embodiments, the first axis of rotation is parallel to the third axis of rotation L.

[0035] The toner cartridge 100 is generally rectangular in shape, such as Figure 1 , Figure 2 and Figure 3 As shown, the main housing 10 includes a first side plate 101, a second side plate 102, a third side plate 103, a fourth side plate 104, a fifth side plate 105, and a sixth side plate 106. The first side plate 101 and the second side plate 102 are spaced apart and opposite each other in the vertical direction, with the first side plate 101 located above the second side plate 102. The third side plate 103 and the fourth side plate 104 are spaced apart and opposite each other in the front-back direction, with the third side plate 103 located in front of the fourth side plate 104. The fifth side plate 105 and the sixth side plate 106 are spaced apart and opposite each other in the left-right direction. The fifth side plate 105 is located to the left of the sixth side plate. The first side plate 101 includes a first sub-side plate 101a and a second sub-side plate 101b connected to each other in the left-right direction. The third side plate 103 includes a third sub-side plate 103a and a fourth sub-side plate 103b connected to each other in the left-right direction. The fourth side plate 104 includes a fifth sub-side plate 104a and a sixth sub-side plate 104b connected to each other in the left-right direction. The third sub-side plate 103a and the fifth sub-side plate 104a are opposite each other in the front-back direction, and the fourth sub-side plate 103b and the sixth sub-side plate 104b are opposite each other in the front-back direction.

[0036] like Figure 5 and Figure 8 As shown, the main housing 10 also includes a seventh side plate 107 and a tenth side plate 101c. The tenth side plate 101c and the first sub-side plate 101a are spaced apart and opposite to each other in the vertical direction, and the first sub-side plate 101a is located above the tenth side plate 101c. In the vertical direction, a first mounting space 109 is formed between the first sub-side plate 101a and the tenth side plate 101c. The second side plate 102 includes an eighth sub-side plate 102a and a ninth sub-side plate 102b connected in the left-right direction, and the eighth sub-side plate 102a is located above the ninth sub-side plate 101c. On the left side of plate 102b, the seventh side plate 107 and the eighth sub-side plate 102a are arranged opposite each other in the vertical direction, and the seventh side plate 107 is located above the eighth sub-side plate 102a. In the vertical direction, a second mounting space 110 is formed between the seventh side plate 107 and the eighth sub-side plate 102a. The first mounting space 109 and the second mounting space 110 are arranged opposite each other in the vertical direction. The tenth side plate 101c is opposite to the seventh side plate 107 in the vertical direction, and the ninth sub-side plate 102b is opposite to the second sub-side plate 101b in the vertical direction.

[0037] like Figure 1 , Figure 2 and Figure 5As shown, the toner cavity 20 includes a first receiving cavity 21 and a second receiving cavity 22 that are interconnected in the left-right direction, and the first receiving cavity 21 is located to the left of the second receiving cavity 22. The fifth side plate 105, the seventh side plate 107, the tenth side plate 101c, the third sub-side plate 103a, and the fifth sub-side plate 104a enclose the first receiving cavity 21. The first mounting space 109 and the second mounting space 110 are located on the upper and lower sides of the toner cavity 20 / first receiving cavity 21, respectively. In other words, in the vertical direction, the first mounting space 109, the toner cavity 20 / first receiving cavity 21, and the second mounting space 110 are arranged in a downward direction. The sixth side plate 106, the ninth sub-side plate 102b, the second sub-side plate 101b, the fourth sub-side plate 103b, and the sixth sub-side plate 104b enclose the second receiving cavity 22.

[0038] The main housing 10 is also provided with a stepped portion 101d formed between the first receiving cavity 21 and the second receiving cavity 22. At least a portion of the stepped portion 101d coincides with the powder outlet 50 in the left-right direction. With this arrangement, a large amount of toner in the second receiving cavity 22 can be prevented from flowing into the first receiving cavity 21, thereby causing the powder outlet 50 to become blocked.

[0039] In some implementations, such as Figure 5 As shown, the side of the tenth side plate 101c facing the first receiving cavity 21 is configured as a plane parallel to the third rotation axis L, or as an inclined surface inclined relative to the third rotation axis L. Specifically, in the vertical direction, the end of the tenth side plate 101c that is closer to the driving force receiving member 40 in the horizontal direction is closer to the third rotation axis L than the end that is farther away from the driving force receiving member 40. The side of the second sub-side plate 101b facing the second receiving cavity 22 is configured as a plane parallel to the third rotation axis L, or as an inclined surface inclined relative to the third rotation axis L. Specifically, in the vertical direction, the end of the second sub-side plate 101b that is closer to the driving force receiving member 40 / tenth side plate 101c in the horizontal direction is closer to the third rotation axis L than the end that is farther away from the driving force receiving member 40 / tenth side plate 101c.

[0040] Continue as Figure 5As shown, the side of the seventh side plate 107 facing the first receiving cavity 21 is set as a plane, which is parallel to the third rotation axis L, or the plane is inclined relative to the third rotation axis L. Specifically, in the vertical direction, the end of the seventh side plate 107 closer to the driving force receiver 40 in the horizontal direction is closer to the third rotation axis L than the end farther away from the driving force receiver 40. The side of the ninth sub-side plate 102b facing the second receiving cavity 22 is also set as a plane, which is parallel to the third rotation axis L, or the plane is inclined relative to the third rotation axis L. Specifically, in the vertical direction, the end of the ninth sub-side plate 102b closer to the driving force receiver 40 in the horizontal direction is closer to the third rotation axis L than the end farther away from the driving force receiver 40. This facilitates the flow of toner from the second receiving cavity 22 toward the first receiving cavity 21.

[0041] The toner cartridge 100 is cut along a direction perpendicular to the left and right direction. The cut surface of the toner cartridge 100 forms at least four corners. In the up and down direction, two of the corners are above the other two corners. At least one of the two upper corners is a right angle, and the two lower corners are rounded.

[0042] In some implementations, such as Figure 6 As shown, the included angle between the tenth side plate 101c and the fifth sub-side plate 104a is a right angle, which can increase the capacity of the first receiving cavity 21. At least one of the following is formed as a rounded chamfer: between the fifth sub-side plate 104a and the seventh side plate 107, between the seventh side plate 107 and the third sub-side plate 103a, and between the third sub-side plate 103a and the tenth side plate 101c. With this configuration, the conveying blade 32 can contact the rounded chamfer and stir the toner at the rounded chamfer, preventing toner from remaining or accumulating at the rounded chamfer. When the toner cartridge 100 is installed in the developing cartridge, the tenth side plate 101c is located above the fifth sub-side plate 104a in the vertical direction. Therefore, the toner at the right angle can fall under its own gravity and will not accumulate at the right angle.

[0043] In some implementations, such as Figure 7As shown, the included angles formed between the second sub-side plate 101b and the fourth sub-side plate 103b, and between the second sub-side plate 101b and the sixth sub-side plate 104b, are both right angles. This increases the capacity of the second receiving cavity 22. At least one of the following is formed as a rounded chamfer: between the ninth sub-side plate 102b and the fourth sub-side plate 103b, and between the ninth sub-side plate 102b and the sixth sub-side plate 104b. With this arrangement, the conveying blade 32 can contact the rounded chamfer to prevent toner residue at the rounded chamfer. When the toner cartridge 100 is installed in the developing cartridge, the second sub-side plate 101b is located above the fourth sub-side plate 103b and the sixth sub-side plate 104b in the vertical direction. Therefore, the right angle is formed above the rounded chamfer, and the toner at the right angle can fall under its own gravity, preventing toner from accumulating at the right angle.

[0044] In some implementations, such as Figure 4 As shown, the powder outlet 50 is connected to the first receiving cavity 21, that is, the powder outlet 50 is located on the third sub-side plate 103a.

[0045] like Figure 3 As shown, the toner cartridge 100 further includes a sealing assembly 60, which includes an actuating element 61, a sealing element 62, and a connecting element 63 for connecting the actuating element 61 and the sealing element 62. The actuating element 61 and the sealing element 62 or the toner outlet 50 are spaced apart in the front-back direction, and the sealing element 62 or the toner outlet 50 is located in front of the actuating element 61. The sealing element 62 includes a connecting port 621 and a sealing part 622 arranged in the left-right direction. The connecting port 621 is used to communicate with the toner outlet 50, so that toner can be conveyed to the developing cartridge through the toner outlet 50 and the connecting port 621. The sealing part 622 is used to seal the toner outlet 50, so that toner cannot pass through the toner outlet 50.

[0046] The actuating member 61 is configured to move in the left and right direction, and the actuating member 61 drives the sealing member 62 to move in the left and right direction through the connecting member 63. The sealing assembly 60 can move between a sealing position and a desealing position. In the sealing position, the powder outlet 50 is sealed by the sealing part 622, and the toner cannot be delivered to the developing cartridge. In the desealing position, at least a portion of the powder outlet 50 is connected to the connecting port 621, and the toner can be delivered to the developing cartridge.

[0047] like Figure 1 , Figure 3 and Figure 8 As shown, at least a portion of the connector 63 is located in the first mounting space 109 and the second mounting space 110. Both the first mounting space 109 and the second mounting space 110 can guide the actuating member 61 to move in the left and right directions, so as to facilitate the movement of the sealing assembly 60 between the sealing position and the unsealing position.

[0048] In some embodiments, when the actuating member 61 moves the sealing member 62 to the left, the sealing assembly 60 moves from the unsealed position to the sealed position; when the actuating member 61 moves the sealing member 62 to the right, the sealing assembly 60 moves from the sealed position to the unsealed position. In this configuration, the connecting port 621 is located to the left of the sealing part 622 in the left-right direction.

[0049] like Figure 3 and Figure 8 As shown, the actuating member 61 includes a base plate 611 and a pushing part 612 disposed on the base plate 611. Under the action of external force, the pushing part 612 and the base plate 611 move together in the left and right direction. The connecting member 63 is connected to the base plate 611. The actuating member 61 also includes at least one first mating part 613. The first sub-side plate 101a and / or the eighth sub-side plate 102a are provided with a first mated part 111 for cooperating with the first mating part 613. Through the mutual cooperation between the first mating part 613 and the first mated part 111, the movement distance of the actuating member 61 / base plate 611 in the left and right direction is limited.

[0050] The base plate 611 includes a first part 611a and a second part 611b connected to each other in the left-right direction, with the first part 611a located to the left of the second part 611b. The vertical dimension of the first part 611a is larger than that of the second part 611b in the vertical direction, meaning that a gap is formed between the first part 611a and the second part 611b. In the vertical direction, the first mating part 613 is configured such that at least one of the upper or lower sides of the first part 611a protrudes relative to the second part 611b. The first mating part 111 includes interconnected... The first mating part 613 and the first mating part 611a are connected. In the front-to-back direction, the first mating part 111a is configured as a protrusion extending from the first sub-side plate 101a and / or the eighth sub-side plate 102a toward a direction away from the powder outlet 50. The first mating part 613 abuts against the first mating part 611a in the left-to-right direction. In the up-down direction, the actuating part 111b is configured as a protrusion extending upward and / or downward from the first mating part 111a. The actuating part 111b is used to prevent the bottom plate 611 / actuator 61 from falling off the main housing 10.

[0051] In some embodiments, as described above, the included angle between the tenth side plate 101c and the fifth sub-side plate 104a is a right angle, and the angle between the fifth sub-side plate 104a and the seventh side plate 107 is a rounded chamfer. Therefore, as Figure 6As shown, in the front-rear direction, a clearance space 112 is formed between the base plate 611 and the main housing 10 / fifth sub-side plate 104a. The clearance space 112 is connected to the second installation space 110. The clearance space 112 is used to avoid a part of the action member 61. It can be understood that the clearance space 112 facilitates the action member 61 to undergo slight deformation during installation, making the action member 61 easy to assemble.

[0052] In some embodiments, the actuating member 61 is installed to the main housing 10 from back to front. During the assembly of the actuating member 61, the base plate 611 is assembled by pressing the first mating part 111 to cause the first mating part 111 to undergo elastic deformation. The first mating part 111 is disposed on the first sub-side plate 101a and / or the eighth sub-side plate 102a. In this configuration, the first mating part 111 is more likely to undergo elastic deformation during the assembly of the actuating member 61, reducing the assembly difficulty of the actuating member 61.

[0053] In some embodiments, the pusher 612 is regarded as a handle, which allows the user to install and remove the toner cartridge 100 by gripping the pusher 612.

[0054] In some embodiments, the first mating part 111 is configured as an elastic arm.

[0055] The toner cartridge 100 is also provided with a limiting plate for limiting the movement distance of the base plate 611 in the left and right directions. In some embodiments, the limiting plate is a fifth side plate 105, which limits the movement distance of the base plate 611 to the left. In this case, the first mating part body 111a limits the movement distance of the base plate 611 to the right. In some embodiments, the limiting plate limits the movement distance of the base plate 611 to the right. In this case, the first mating part body 111a limits the movement distance of the base plate 611 to the left. With this arrangement, under the combined action of the limiting plate and the first mating part body 111a, the actuating member 61 / base plate 611 is not easily separated from the main housing 10 during the movement in the left and right directions.

[0056] like Figure 9 As shown, the third rotation axis L of the toner conveyor 30 is located in front of the cavity center line M of the toner cavity 20 in the front-back direction. The cavity center line M is parallel to the left-right direction and passes through the midpoint of the length h of the toner cavity 20 in the front-back direction. In other words, in the front-back direction, the third rotation axis L is closer to the toner outlet 50 than the cavity center line M. With this arrangement, the toner conveyor 30 or the conveying blade 32 can more effectively stir the toner near the toner outlet 50, preventing toner agglomeration and blockage, which would affect the toner conveying.

[0057] like Figure 1 , Figure 3 and Figure 8 As shown, the toner cartridge 100 further includes a pre-positioning assembly 70 for pre-positioning the actuating member 61. The pre-positioning assembly 70 includes an interacting second mating portion 71 and a second mated portion 72. The connecting member 63 has a rearward-facing rear side surface 631. The second mating portion 71 is configured as a protrusion extending from the rear side surface 631 in a direction away from the toner outlet 50. The second mated portion 72 is configured as a through hole located on the base plate 611 and extending in the front-rear direction, or the second mated portion 72 is configured as a groove located on the base plate 611 and opening forward. Through the engagement between the protrusion and the through hole, or the engagement between the protrusion and the groove, the base plate 611 / actuating member 61 and the connecting member 63 can be connected at a predetermined position, facilitating the installation and fixation of the base plate 611. In some embodiments, after the base plate 611 and the connecting member 63 are connected at the predetermined position, a fastener is used to fix the base plate 611 and the connecting member 63. The fastener can be a screw.

[0058] In some embodiments, the second mating part 71 is provided as a groove or a through hole, and the second mating part 72 is provided as a protrusion.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the toner cartridge 100 also includes a sub-shell 80 and a gear mounting cavity 81 formed inside the sub-shell 80. The gear mounting cavity 81 is used to mount the drive force receiving member 40. The sub-shell 80 is connected to the main shell 10. The sub-shell 80 includes an eighth side plate 82 and at least one ninth side plate 83. The eighth side plate 82 and the ninth side plate 83 are connected to each other. The ninth side plate 83 is used to connect the eighth side plate 82 and the main shell 10. Specifically, the ninth side plate 83 is connected to the first sub-side plate 101a and / or the eighth sub-side plate 102a. In the left-right direction, the eighth side plate 82 is located to the left of the fifth side plate 105. The gear mounting cavity 81 is formed between the eighth side plate 82 and the fifth side plate 105.

[0060] In some embodiments, the sub-housing 80 is integrally formed with the main housing 10.

[0061] like Figure 4As shown, the eighth side plate 82 is also provided with a first guide portion 821 for guiding the installation of the driving force receiver 40. The first guide portion 821 is configured as multiple ribs on the side of the eighth side plate 82 facing the gear mounting cavity 81. The sub-housing 80 also includes an exposure port 84 formed between the eighth side plate 82 and the fifth side plate 105. The driving force receiver 40 is exposed to the outside through the exposure port 84 and receives driving force. The driving force receiver 40 can be installed into the gear mounting cavity 81 through the exposure port 84 under the guidance of the first guide portion 821.

[0062] like Figure 1 As shown, the sub-shell 80 has a rearward opening 87 formed between the eighth side plate 82 and the fifth side plate 105, and communicates with the gear mounting cavity 81. The opening 87 and the exposed opening 84 are spaced apart and opposite to each other in the front-rear direction. The opening 87 facilitates the demolding of the toner box 100 during manufacturing.

[0063] like Figure 1 and Figure 2 As shown, the toner cartridge 100 is further provided with a second guide portion 822 located on the eighth side plate 82 and a third guide portion 106a located on the sixth side plate 106. Both the second guide portion 822 and the third guide portion 106a are used to guide the installation of the toner cartridge 100. The second guide portion 822 is configured as a protrusion extending from the side of the eighth side plate 82 away from the gear mounting cavity 81 in a direction away from the gear mounting cavity 81. The third guide portion 106a is configured as a protrusion extending from the side of the sixth side plate 106 away from the toner cavity 20 in a direction away from the toner cavity 20.

[0064] In some implementations, such as Figure 1 , Figure 2 and Figure 8 As shown, the second guide portion 822 is cylindrical, and the third guide portion 106a is non-cylindrical or irregularly shaped. The third guide portion 106a includes at least a third part 106a1 and a fourth part 106a2 connected along the circumferential direction of the third guide portion 106a. In the direction intersecting with the left and right directions, the size of the third part 106a1 is larger than the size of the fourth part 106a2. With this arrangement, when the toner cartridge 100 is installed in the developing cartridge, the toner cartridge 100 is less likely to shake or sway during the opening of the toner outlet 50, and the toner cartridge 100 can deliver toner to the developing cartridge more stably.

[0065] In some specific embodiments, when the toner cartridge 100 is installed in the developing cartridge and the actuating member 61 is pushed to the right to open the toner outlet 50, the toner cartridge 100 tends to swing outward on the left and inward on the right in the left-right direction. As mentioned above, the second guide part 822 is set in a cylindrical shape, and the third guide part 106a is set in a non-cylindrical shape or an irregular shape. When the compression springs in the developing cartridge used to squeeze the second guide part 822 and the third guide part 106a are the same, the pressure on the left side of the toner cartridge 100 is greater, and the toner cartridge 100 is less likely to swing.

[0066] After the driving force receiver 40 is installed into the gear mounting cavity 81, the driving force receiver 40 contacts the rib to prevent the driving force receiver 40 from falling off. At the same time, it can also prevent the eighth side plate 82 from deforming after the toner cartridge 100 is installed into the developing cartridge, so that the second guide part 822 cannot be stably supported.

[0067] In some embodiments, the gear mounting cavity 81 extends through the front-rear direction. Under the action of the first guide portion 821, the eighth side plate 82 can undergo elastic deformation. With this arrangement, the assembly difficulty of the drive force receiver 40 can be reduced when it is installed along the first guide portion 821.

[0068] like Figure 2 , Figure 3 and Figure 5 As shown, the toner cartridge 100 is also provided with a first support portion 90 for supporting the driving force receiving member 40 and a second support portion for supporting the rotating shaft 31. The second support portion is used to support the right end of the rotating shaft 31. In some embodiments, the first support portion 90 can also be used to support the left end of the rotating shaft 31. With such a configuration, the toner conveying member 30 can be stably driven and rotated.

[0069] In some implementations, such as Figure 4 As shown, the exposed port 84 is configured as a U-shaped port. In the specific assembly process, the driving force receiving component 40 is first installed to the first support part 90 through the U-shaped port, and then the toner conveying component 30 is installed, so that the driving force receiving component 40 is supported by the rotating shaft 31 and the first support part 90 at the same time.

[0070] In some embodiments, the first support portion 90 is configured as a protrusion extending from the side of the fifth side plate 105 facing the gear mounting cavity 81 toward a direction away from the sixth side plate 106. A first receiving portion is formed in the protrusion for the left end of the rotating shaft 31 to pass through. The first receiving portion is configured as a through hole extending in the left-right direction. The left end of the rotating shaft 31 can be supported by the first support portion 90 through the first receiving portion.

[0071] In some embodiments, the second support portion is configured as a protrusion extending from the side of the sixth side plate 106 facing the toner cavity 20 toward the direction close to the fifth side plate 105. A second receiving portion is formed in the protrusion for the right end of the rotating shaft 31 to pass through. The second receiving portion is configured as a through hole extending in the left-right direction, or the second receiving portion is configured as a groove opening toward the toner cavity 20. The right end of the rotating shaft 31 can be supported by the second support portion through the second receiving portion.

[0072] In some implementations, such as Figure 2 and Figure 4 As shown, the sub-housing 80 is also provided with a baffle 85 for protecting the driving force receiving member 40. In the left-right direction, the baffle 85 is connected to both the eighth side plate 82 and the fifth side plate 105. The baffle 85 is used to prevent impurities from entering the gear mounting cavity 81, and can also enhance the strength of the sub-housing 80, so that the second guide part 822 is stably supported.

[0073] In some embodiments, the baffle is also connected to the ninth side plate 83. With this arrangement, the baffle 85 can more effectively protect the drive force receiver 40, and at the same time, it can also improve the strength of the sub-housing 80.

[0074] The developing cartridge is also provided with a toner inlet for receiving toner supplied by the toner cartridge 100 and a switch for controlling the opening or closing of the toner inlet, such as... Figure 2 As shown, the sub-housing 80 is also provided with a trigger part 86 for triggering the switch. When the toner cartridge 100 is installed into the developing cartridge, the trigger part 86 triggers the switch, causing the switch to open, and the toner can reach the interior of the developing cartridge through the toner inlet. The trigger part 86 is configured as at least one protrusion extending from the side of the fifth side plate 105 facing the gear mounting cavity 81 toward the gear mounting cavity 81. The at least one protrusion is connected to the first support part 90. This configuration can strengthen the strength of the first support part 90.

[0075] [Beneficial Effects]

[0076] Compared with the prior art, the toner cartridge, the developing cartridge having the toner cartridge, and the processing cartridge having the developing cartridge provided by this utility model have the following beneficial effects:

[0077] In the first aspect, the second receiving cavity is formed by the sixth side plate 106, the ninth sub-side plate 102b, the second sub-side plate 101b, the fourth sub-side plate 103b and the sixth sub-side plate 104b of the main housing 10, wherein the included angles formed between the second sub-side plate 101b and the fourth sub-side plate 103b and between the second sub-side plate 101b and the sixth sub-side plate 104b are both right angles. With this arrangement, the capacity of the second receiving cavity 22 can be increased.

[0078] Secondly, the first receiving cavity 21 is formed by the fifth side plate 105, the seventh side plate 107, the tenth side plate 101c, the third sub-side plate 103a and the fifth sub-side plate 104a of the main housing 10. The included angle between the tenth side plate 101c and the fifth sub-side plate 104a is a right angle. With this configuration, the capacity of the first receiving cavity 21 is increased, and the capacity of the toner cavity 20 is further increased. Users no longer need to frequently replace the toner cartridge 100 or replenish the toner, thus improving the user experience.

[0079] Thirdly, based on the first and second aspects, rounded chamfers are formed between the ninth sub-side plate 102b and the fourth sub-side plate 103b, and between the ninth sub-side plate 102b and the sixth sub-side plate 104b. At least one of the following is formed: a rounded chamfer between the fifth sub-side plate 104a and the seventh side plate 107, between the seventh side plate 107 and the third sub-side plate 103a, and between the third sub-side plate 103a and the tenth side plate 101c. With this configuration, the conveying blade 32 can contact the rounded chamfer and stir the toner at the rounded chamfer, preventing toner from remaining or accumulating at the rounded chamfer, thereby avoiding toner waste.

[0080] Fourthly, in the front-back direction, the third rotation axis L of the toner conveyor 30 is closer to the toner outlet 50 than the cavity centerline M of the toner chamber 20 in the front-back direction. With this arrangement, the toner conveyor 30 or the conveying blade 32 can more effectively stir the toner near the toner outlet 50, preventing toner agglomeration and blockage, which would affect the toner conveying.

[0081] Fifthly, the main housing 10 has a stepped portion 101d formed between the first receiving cavity 21 and the second receiving cavity 22. At least a portion of the stepped portion 101d coincides with the powder outlet 50 in the left-right direction. With this arrangement, a large amount of toner in the second receiving cavity 22 can be prevented from flowing into the first receiving cavity 21, thereby causing the powder outlet 50 to become blocked.

[0082] Sixthly, the toner cartridge 100 is further provided with a second guide portion 822 and a third guide portion 106a, both used for guiding the installation of the toner cartridge 100. The second guide portion 822 is cylindrical, and the third guide portion 106a is non-cylindrical or irregularly shaped. The third guide portion 106a includes at least a third part 106a1 and a fourth part 106a2 connected along the circumferential direction of the third guide portion 106a. In the direction intersecting with the left and right directions, the size of the third part 106a1 is larger than the size of the fourth part 106a2. With this arrangement, when the toner cartridge 100 is installed in the developing cartridge and the toner outlet 50 is opened, the toner cartridge 100 is less likely to shake or sway, and the toner cartridge 100 can deliver toner to the developing cartridge more stably.

[0083] In the seventh aspect, in the front-rear direction, a clearance space 112 is formed between the base plate 611 and the main housing 10 / the fifth sub-side plate 104a. The clearance space 112 is connected to the second mounting space 110. By setting the clearance space 112, during the process of assembling the actuating member 61 to the main housing 10, the clearance space 112 can allow the actuating member 61 to undergo slight deformation during installation, making the actuating member 61 easier to assemble.

[0084] Eighthly, the sub-shell 80 is further provided with a trigger part 86 for triggering a switch provided in the developing cartridge. The switch controls the opening or closing of the toner inlet for receiving toner supplied by the toner cartridge 100. When the toner cartridge 100 is installed in the developing cartridge, the trigger part 86 triggers the switch, causing the switch to open, and the toner can reach the interior of the developing cartridge through the toner inlet. The trigger part 86 is configured as at least one protrusion extending from the side of the fifth side plate 105 facing the gear mounting cavity 81 toward the gear mounting cavity 81. Compared with the existing method of using the edge of the fifth side plate as the trigger part, the technical solution provided by this utility model does not require increasing the thickness of the fifth side plate. Therefore, the material cost of the toner cartridge 100 will not increase, and it is also less likely to cause deformation of the main shell 10 after injection molding.
