Description

Technical Field

[0001] This invention relates to the field of toner supply technology for image forming apparatuses, and in particular to a toner cartridge for supplying toner to an image forming apparatus, which can be detachably installed on an image forming apparatus (e.g., a copier, fax machine, printer, word processor, typewriter, etc.) to supply toner. Background Technology

[0002] Image forming apparatuses typically include an image processing unit and a developing unit. The developing unit uses toner supplied to develop the electrostatic latent image formed on the image processing unit to create a visible image on a medium such as paper. Toner, being a consumable, needs to be continuously replenished to the image forming apparatus. Generally, a toner cartridge, detachably mounted to the image forming apparatus and capable of holding a certain amount of toner, is used to supply toner to the developing unit.

[0003] To identify whether the toner cartridge is properly installed when it is installed in the image forming apparatus, the image forming apparatus is provided with a first conductive part and a second conductive part, and the toner cartridge is required to be provided with a first conductive element and a second conductive element that are electrically connected. So that when the toner cartridge is installed in the predetermined position of the image forming apparatus, the first conductive element of the toner cartridge forms a contact electrical connection with the first conductive part of the image forming apparatus, and the second conductive element of the toner cartridge forms a contact electrical connection with the second conductive part of the image forming apparatus, thereby triggering the electrical signal response unit of the image forming apparatus to obtain a predetermined response signal indicating that the toner cartridge has been successfully installed in the predetermined position of the image forming apparatus, and thus controlling the toner cartridge to supply toner.

[0004] However, the first and second conductive components of existing toner cartridges are elastic metal sheets or elastic metal wires. To ensure elastic deformation capability, the thickness of these sheets or wires is very thin. Now, under the principles of energy conservation, environmental protection, and sustainable development, toner cartridges are recycled and reused. Because the first and second conductive components of existing toner cartridges are elastic metal sheets or wires, and these thin sheets or wires are prone to excessive deformation, the first and second conductive components of recycled toner cartridges cannot form a stable electrical contact with the first and second conductive parts of the image forming apparatus. This affects the stability and reliability of the electrical contact, consequently impacting the reliability of the toner cartridge installation and the user experience. Furthermore, if the original elastic metal sheets or wires are replaced with new ones during the recycling process, it increases the number of steps in the recycling process, significantly increasing the production cost. Summary of the Invention

[0005] To achieve the main objective of this invention, this invention provides a toner cartridge that can form a stable and reliable electrical contact with an image forming apparatus, and can still form a stable and reliable electrical contact with the image forming apparatus after recycling and reuse, thereby improving the recycling rate of the toner cartridge, reducing the production process of recycling and reuse, reducing the production cost of recycling and reuse, and improving the installation reliability of the toner cartridge, thereby improving the user experience.

[0006] To achieve the main objective of this invention, a toner cartridge is provided for detachable installation in an image forming apparatus. The cartridge includes a toner cartridge housing, a switch plate, and a conductive module. The toner cartridge housing has a toner cavity for containing toner, and a toner outlet communicating with the toner cavity is provided on the peripheral wall of the housing. The switch plate is movably supported on the housing to open or close the toner outlet. The conductive module includes a mounting base, a conductive plate, and an elastic element. A guide groove is provided at the upper end of the housing, with its inlet extending through the rear end. A mounting groove is provided at the front end of the guide groove, and the mounting base is detachably installed in the groove. The conductive plate is movably supported on the mounting base in a vertical direction. The conductive plate includes a flat plate, a first vertical plate, and a second vertical plate. The first and second vertical plates are arranged side-by-side at the upper end of the flat plate in a horizontal direction. The elastic element forces the flat plate to move upward away from the mounting base, allowing the first vertical plate to be electrically connected to a first conductive part of the image forming apparatus, and the second vertical plate to be electrically connected to a second conductive part of the image forming apparatus.

[0007] As can be seen from the above scheme, during the process of installing the toner cartridge of the present invention into the image forming apparatus, the first conductive part and the second conductive part of the image forming apparatus enter the guide groove at the upper end of the toner cartridge housing from the inlet of the guide groove at the upper end of the toner cartridge housing, so that the first vertical plate and the second vertical plate of the conductive module in the guide groove are aligned with the first conductive part and the second conductive part of the image forming apparatus, respectively, until the toner cartridge of the present invention is installed in the predetermined position of the image forming apparatus. Due to the elastic element, the flat plate of the conductive plate is forced to move upward away from the mounting base, so as to drive the first vertical plate and the second vertical plate on the flat plate to maintain a stable upward movement. The movement causes the first vertical plate of the toner cartridge to form a stable contact electrical connection with the first conductive part of the image forming apparatus, and the second vertical plate of the toner cartridge to form a stable contact electrical connection with the second conductive part of the image forming apparatus. This improves the stable and reliable contact electrical connection between the toner cartridge and the image forming apparatus, thereby reliably triggering the electrical signal response unit of the image forming apparatus to obtain a predetermined response signal indicating that the toner cartridge has been successfully installed at a predetermined position in the image forming apparatus. At this time, the pushing structure of the image forming apparatus pushes the switch plate of the toner cartridge to move to open the toner outlet, thereby supplying toner to the image forming apparatus.

[0008] When the toner cartridge of the present invention is completely removed from the image forming apparatus, the switch plate of the toner cartridge of the present invention is reset and moved to close the toner outlet to prevent toner leakage from the toner cartridge housing.

[0009] Because the conductive plate of the conductive module of the toner cartridge of the present invention is a rigid plate, the rigid conductive plate includes a flat plate, a first vertical plate, and a second vertical plate. Both the first and second vertical plates are rigid plates. Compared with existing elastic metal sheets or elastic metal rods, the flat plate, the first vertical plate, and the second vertical plate of the present invention are thicker to avoid the risk of deformation of the flat plate, the first vertical plate, and the second vertical plate. Thus, the elastic element forces the flat plate of the conductive plate to move upward away from the mounting base, thereby driving the first and second vertical plates on the flat plate to maintain a stable upward movement. The rigid and thick first vertical plate can form a stable contact electrical connection with the first conductive part of the image forming device, and the rigid and thick second vertical plate can form a stable contact electrical connection with the second conductive part of the image forming device. This improves the formation of a stable and reliable contact electrical connection between the toner cartridge and the image forming device, thereby improving the installation reliability of the toner cartridge.

[0010] In today's context of energy conservation, environmental protection, and sustainable development, even if the toner cartridge of this invention is recycled and reused multiple times, the conductive plate of the conductive module of the toner cartridge of this invention is a rigid plate. The rigid conductive plate includes a flat plate, a first vertical plate, and a second vertical plate. Both the first and second vertical plates are rigid plates. Compared with existing elastic metal sheets or elastic metal rods, the flat plate, the first vertical plate, and the second vertical plate of this invention are thicker to avoid the risk of deformation. This ensures that after multiple recycling and reuse, the rigid and thick first vertical plate can still form a stable contact electrical connection with the first conductive part of the image forming device, and the rigid and thick second vertical plate can still form a stable contact electrical connection with the second conductive part of the image forming device. This allows the toner cartridge to maintain a stable and reliable contact electrical connection with the image forming device after multiple recycling and reuse, thereby improving the recycling and reuse rate of the toner cartridge, reducing the production process of recycling and reuse, and lowering the production cost of recycling and reuse.

[0011] Therefore, the toner cartridge of the present invention can form a stable and reliable contact electrical connection with the image forming apparatus, and can still form a stable and reliable contact electrical connection with the image forming apparatus after recycling and reuse, thereby improving the recycling rate of the toner cartridge, reducing the production process of recycling and reuse, reducing the production cost of recycling and reuse, and improving the installation reliability of the toner cartridge, thereby improving the user experience.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0049] See Figures 1 to 22 This embodiment discloses a toner cartridge 10 that can be detachably installed in an image forming apparatus, including a toner cartridge housing 11 and a switch plate 1151. The toner cartridge housing 11 has a toner cartridge cavity 112 for containing toner, and the peripheral wall of the toner cartridge housing 11 has a toner outlet 115 that communicates with the toner cartridge cavity 112. The switch plate 1151 is movably supported on the toner cartridge housing 11 to open or close the toner outlet 115.

[0050] Specifically, a baffle 1154 protrudes from the peripheral wall of the powder hopper housing 11, and a through hole is provided through the baffle 1154. A linkage rod 1152 protrudes from the switch plate 1151 and is movably disposed through the through hole of the baffle 1154. A hook 1153 is provided at the end of the linkage rod 1152 away from the switch plate 1151. The hook 1153 can be hooked onto the end face of the baffle 1154 away from the switch plate 1151. A return spring 1155 is sleeved on the linkage rod 1152 and presses against the baffle 1154 and the switch plate 1151. Thus, under the elastic restoring force of the return spring 1155, the switch plate 1151 can be forced to move away from the baffle 1154 to close the powder outlet 115 of the powder hopper housing 11. At this time, the hook 1153 is hooked onto the end face of the baffle 1154 away from the switch plate 1151 to ensure that the switch plate 1151 stably closes the powder outlet 115. When the toner cartridge 10 is installed in the predetermined position of the image forming apparatus, the push structure of the image forming apparatus pushes the switch plate 1151 toward the baffle 1154 to open the toner outlet 115 of the toner cartridge housing 11. At this time, the reset spring 1155 is in a compressed state, thereby supplying toner to the image forming apparatus.

[0051] Furthermore, the toner cartridge 10 in this embodiment also includes a conductive module 12, which includes a mounting base 121, a conductive plate 123, and an elastic element. The upper end of the toner cartridge housing 11 is provided with a guide groove 111, the inlet 1112 of the guide groove 111 is provided through the rear end of the toner cartridge housing 11, the front end of the guide groove 111 is provided with a mounting groove 1111, the mounting base 121 is detachably mounted in the mounting groove 1111, and the conductive plate 123 is movably supported on the mounting base 121 in the vertical direction.

[0052] Furthermore, in this embodiment, the conductive plate 123 includes a flat plate 1231, a first vertical plate 1232, and a second vertical plate 1233. The first vertical plate 1232 and the second vertical plate 1233 are arranged side by side on the upper end of the flat plate 1231 in the left-right direction. An elastic member forces the flat plate 1231 to move upward away from the mounting base 121, so that the first vertical plate 1232 is used to electrically connect with the first conductive part of the image forming apparatus, and the second vertical plate 1233 is used to electrically connect with the second conductive part of the image forming apparatus.

[0053] During the installation of the toner cartridge 10 of this embodiment into the image forming apparatus, the first conductive part and the second conductive part of the image forming apparatus enter the guide groove 111 at the upper end of the toner cartridge housing 11 from the inlet 1112 of the guide groove 111 at the upper end of the toner cartridge housing 11. This aligns the first vertical plate 1232 and the second vertical plate 1233 of the conductive module 12 in the guide groove 111 with the first conductive part and the second conductive part of the image forming apparatus, respectively. This continues until the toner cartridge 10 of this embodiment is installed at the predetermined position of the image forming apparatus. Due to the elastic element, the flat plate 1231 of the conductive plate 123 is forced to move upward away from the mounting base 121, thereby driving the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231. 1233 maintains a stable upward movement, causing the first vertical plate 1232 of the toner cartridge 10 to form a stable contact electrical connection with the first conductive part of the image forming apparatus, and the second vertical plate 1233 of the toner cartridge 10 to form a stable contact electrical connection with the second conductive part of the image forming apparatus. This improves the stable and reliable contact electrical connection between the toner cartridge 10 and the image forming apparatus, so as to reliably trigger the electrical signal response unit of the image forming apparatus to obtain a predetermined response signal indicating that the toner cartridge 10 has been successfully installed in the predetermined position of the image forming apparatus. At this time, the pushing structure of the image forming apparatus pushes the switch plate 1151 of the toner cartridge 10 to move to open the toner outlet 115, thereby supplying toner to the image forming apparatus.

[0054] When the toner cartridge 10 of this embodiment is completely removed from the image forming apparatus, the switch plate 1151 of the toner cartridge 10 of this embodiment is forced to move to close the toner outlet 115 under the elastic restoring force of the reset spring 1155, so as to prevent toner leakage from the toner hopper housing 11 of the toner cartridge 10.

[0055] Because the conductive plate 123 of the conductive module 12 of the toner cartridge 10 in this embodiment is a rigid plate, the rigid conductive plate 123 includes a flat plate 1231, a first vertical plate 1232, and a second vertical plate 1233, making both the first vertical plate 1232 and the second vertical plate 1233 rigid plates. Compared with existing elastic metal sheets or elastic metal rods, the flat plate 1231, the first vertical plate 1232, and the second vertical plate 1233 in this embodiment are thicker to avoid the risk of deformation of the flat plate 1231, the first vertical plate 1232, and the second vertical plate 1233, thereby ensuring the conductivity is forced by the elastic element. The flat plate 1231 of plate 123 moves upward away from the mounting base 121 to drive the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231 to move upward steadily. The rigid and thick first vertical plate 1232 can form a stable contact electrical connection with the first conductive part of the image forming apparatus, and the rigid and thick second vertical plate 1233 can form a stable contact electrical connection with the second conductive part of the image forming apparatus, thereby improving the formation of a stable and reliable contact electrical connection between the toner cartridge 10 and the image forming apparatus, and thus improving the installation reliability of the toner cartridge 10.

[0056] In today's context of energy conservation, environmental protection, and sustainable development, even if the toner cartridge 10 of this embodiment is recycled and reused multiple times, the conductive plate 123 of the conductive module 12 of the toner cartridge 10 in this embodiment is a rigid plate. The rigid conductive plate 123 includes a flat plate 1231, a first vertical plate 1232, and a second vertical plate 1233, making both the first vertical plate 1232 and the second vertical plate 1233 rigid plates. Compared with existing elastic metal sheets or elastic metal rods, the flat plate 1231, the first vertical plate 1232, and the second vertical plate 1233 of this embodiment are thicker to avoid the flat plate 1231, the first vertical plate 1232, and the second vertical plate 1233 being too thick. The plate 1233 is at risk of deformation, so that after multiple recyclings and reuses, the rigid and thick first vertical plate 1232 of the toner cartridge 10 in this embodiment can still form a stable contact electrical connection with the first conductive part of the image forming apparatus, and the rigid and thick second vertical plate 1233 can still form a stable contact electrical connection with the second conductive part of the image forming apparatus. This allows the toner cartridge 10 to still form a stable and reliable contact electrical connection with the image forming apparatus after multiple recyclings and reuses, thereby improving the recycling rate of the toner cartridge 10, reducing the production process of recycling and reuse, and lowering the production cost of recycling and reuse.

[0057] Therefore, in this embodiment, the toner cartridge 10 can form a stable and reliable electrical contact with the image forming apparatus, and can still form a stable and reliable electrical contact with the image forming apparatus after recycling and reuse, thereby improving the recycling rate of the toner cartridge 10, reducing the production process of recycling and reuse, reducing the production cost of recycling and reuse, and improving the installation reliability of the toner cartridge 10, thereby improving the user experience.

[0058] To further enhance structural rigidity, the first vertical plate 1232 in this embodiment is arranged as a triangular plate, and the second vertical plate 1233 in this embodiment is also arranged as a triangular plate.

[0059] Preferably, the flat plate 1231, the first vertical plate 1232, and the second vertical plate 1233 are integrally formed into a conductive plate 123, which is made of conductive metal or conductive plastic.

[0060] Combination Figures 14 to 18 In this embodiment, the mounting base 121 of the conductive module 12 has a receiving cavity 122, and a guide post 1217 extending vertically is provided in the receiving cavity 122. The flat plate 1231 is located in the receiving cavity 122 and has a guide hole 12312 extending through it. The guide hole 12312 is movably sleeved on the guide post 1217. The elastic element is a compression spring 124, which is sleeved on the guide post 1217 and presses against the lower end face of the flat plate 1231 and the lower cavity face of the receiving cavity 122. The first vertical plate 1232 and the second vertical plate 1233 are respectively arranged to extend upward through the upper end of the mounting base 121, so that the compression spring 124 can stably force the flat plate of the conductive plate 123 under the action of elastic restoring force. 1231 moves upward away from the mounting base 121 to drive the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231 to move steadily upward, thereby improving the working stability and reliability of the first vertical plate 1232 and the second vertical plate 1233. The flat plate 1231 of the conductive plate 123 is movably sleeved on the guide post 1217 through the guide hole 12312, so that the guide post 1217 directionally guides the movement of the flat plate 1231, thereby improving the smoothness and accuracy of the upward movement of the flat plate 1231 of the conductive plate 123 away from the mounting base 121, and thus improving the smoothness and accuracy of the upward movement of the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231.

[0061] To further improve the stability and accuracy of the upward movement of the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231, this embodiment uses two guide posts 1217, two guide holes 12312, and two compression springs 124. One guide hole 12312 is located on the side of the first vertical plate 1232 away from the second vertical plate 1233, and the other guide hole 12312 is located on the side of the second vertical plate 1233 away from the first vertical plate 1232. One guide hole 12312 is movably fitted onto one guide post 1217, and one compression spring 124 is fitted onto one guide post 1217.

[0062] To further improve the stability and accuracy of the upward movement of the first vertical plate 1232 and the second vertical plate 1233 on the flat plate 1231, a guide rail 1221 is provided in the accommodating cavity 122 of this embodiment. The guide rail 1221 extends in the vertical direction, and a through groove 12311 is provided through the flat plate 1231. The through groove 12311 of the flat plate 1231 is movably fitted on the guide rail 1221 to improve the stability and accuracy of the upward movement of the flat plate 1231 of the conductive plate 123, thereby improving the stability and accuracy of the upward movement of the first vertical plate 1232 and the second vertical plate 1233.

[0063] To facilitate the easy assembly and disassembly of the conductive module 12, the lower end of the mounting base 121 in this embodiment has a lower opening. A lower end cover 1216 is fitted over the lower opening of the mounting base 121. The lower end cover 1216 and the mounting base 121 are detachably connected by a snap-fit ​​structure 1218, so that the lower end cover 1216 fits over the lower opening of the mounting base 121 to form an accommodating cavity 122 between them. A guide post 1217 is disposed on the lower end cover 1216, so that the compression spring 124 presses against the flat plate 1231 and the lower end cover 1216. Specifically, the upper end of the mounting base 121 in this embodiment has a limiting hole 1215 corresponding to the guide post 1217. The upper end of the guide post 1217 is inserted into the limiting hole 1215 to limit the guide post 1217, thereby improving the accuracy of the guide post 1217 in guiding the movement of the flat plate 1231.

[0064] In order to securely mount the mounting base 121 onto the toner cartridge housing 11 of the toner box 10 and improve the working accuracy and stability of the first vertical plate 1232 and the second vertical plate 1233 on the mounting base 121, in this embodiment, the front end of the mounting base 121 is provided with a first protrusion 1211, and the front end of the mounting groove 1111 is provided with a first limiting plate 1112. The first protrusion 1211 is detachably fastened to the lower end surface of the first limiting plate 1112 to securely restrict the front end of the mounting base 121 within the mounting groove 1111 in the vertical direction. In addition, in this embodiment, the rear end of the mounting base 121 is provided with a second protrusion 1212, and the rear end of the mounting groove 1111 is provided with a second limiting plate 1113. The second protrusion 1212 is detachably fastened to the lower end surface of the second limiting plate 1113 to securely restrict the rear end of the mounting base 121 within the mounting groove 1111 in the vertical direction, thereby securing the entire mounting base 121 within the mounting groove 1111 in the vertical direction.

[0065] To improve the installation accuracy of the mounting base 121 and enhance the working accuracy and stability of the first vertical plate 1232 and the second vertical plate 1233 on the mounting base 121, in this embodiment, the mounting base 121 has a first positioning block 1213 at its front end and a first positioning groove 1114 at its front end. The first positioning block 1213 can be detachably inserted into the first positioning groove 1114 to stably restrict the front end of the mounting base 121 in the front-back and left-right directions. Furthermore, in this embodiment, the mounting base 121 has a second positioning block 1214 at its rear end and a second positioning groove 1115 at its rear end. The second positioning block 1214 can be detachably inserted into the second positioning groove 1115 to stably restrict the rear end of the mounting base 121 in the front-back and left-right directions, thereby stably restricting the mounting base 121 as a whole in the front-back and left-right directions.

[0066] Combination Figures 19 to 22In this embodiment, the toner cartridge housing 11 has a toner discharge chamber 113 communicating with the toner cartridge cavity 112. The toner outlet 115 is provided through the toner discharge chamber 113. The toner cartridge 10 also includes a toner feeding frame 1131, a first driven head 1134, a docking sleeve 1133, a first spring 1135, and a magnetic suction element 1136. The toner feeding frame 1131 is rotatably supported in the toner discharge chamber 113, and the outer periphery of the toner feeding frame 1131 is provided with a spiral blade 1132. The extended end of the toner feeding frame 1131 extends out of the rear end of the toner discharge chamber 113 and is fitted with the docking sleeve 1133. The circumference of the docking sleeve 1133 is... The wall is provided with a first sliding groove 11331, which extends in the front-rear direction. A first driven head 1134 is used to dock with a first driving head of the image forming apparatus to receive the rotational driving force of the first driving head. The first driven head 1134 is provided with a first sliding buckle 11341, which is movably located in the first sliding groove 11331. A magnetic suction member 1136 is provided on the first driven head 1134 and is used to magnetically attract the first driving head of the image forming apparatus. A first spring 1135 is pressed between the magnetic suction member 1136 and the docking sleeve 1133.

[0067] During the installation of the toner cartridge 10 into the image forming apparatus, since the first spring 1135 presses against the magnetic suction member 1136 and the docking sleeve 1133, the elastic restoring force of the first spring 1135 forces the magnetic suction member 1136 to drive the first driven head 1134 to extend outward away from the docking sleeve 1133. This allows the first driven head 1134 to have a slight oscillation capability relative to the docking sleeve 1133, thereby enabling the first driven head 1134 to smoothly engage with the first drive head of the image forming apparatus, improving the installation smoothness of the toner cartridge 10. Furthermore, the first driven head 1134... The magnetic suction member 1136 on the image forming device 4 magnetically attracts the first drive head of the image forming apparatus to improve the stability of the engagement between the first driven head 1134 and the first drive head of the image forming apparatus. As the toner cartridge 10 continues to be installed to the predetermined position of the image forming apparatus, the first drive head of the image forming apparatus pushes the first driven head 1134 to move inward toward the docking sleeve 1133. Since the first sliding buckle 11341 of the first driven head 1134 is movably located within the first sliding groove 11331 of the docking sleeve 1133, the first driven head 1134 is guided by the limiting position of the first sliding groove 11331 to move inward. 1134 moves smoothly in the front-to-back direction towards the inward retraction of the mating sleeve 1133. Under the magnetic attraction of the magnetic attraction member 1136 on the first driven head 1134 and the first driving head of the image forming apparatus, the first driving head of the image forming apparatus is prevented from disengaging from the first driven head 1134 during the process of pushing the first driven head 1134 towards the inward retraction of the mating sleeve 1133. This improves the mating and engagement stability between the first driven head 1134 of the toner cartridge 10 and the first driving head of the image forming apparatus. Afterward, the first driving head of the image forming apparatus rotates to drive... The first driven head 1134 rotates, which synchronously drives the magnetic suction component 1136, the docking sleeve 1133 and the powder feeding frame 1131 to rotate. Since the outer periphery of the powder feeding frame 1131 is provided with spiral blades 1132, the spiral blades 1132 can quantitatively and stably supply the toner in the powder discharge chamber 113 to the powder outlet 115, thereby ensuring that the powder outlet 115 quantitatively and stably supplies toner to the image forming apparatus, so as to avoid a large amount of toner in the powder hopper chamber 112 impacting the powder outlet 115 and causing the powder outlet 115 to explode, thereby improving the quantitative stability of the toner box 10 supplying toner to the image forming apparatus.

[0068] Specifically, both the first driving head of the image forming apparatus and the magnetic 1136 of the toner cartridge 10 are made of magnetic materials, and the polarities of the first driving head of the image forming apparatus and the magnetic 1136 of the toner cartridge 10 are opposite, so that the first driving head of the image forming apparatus and the magnetic 1136 of the toner cartridge 10 can attract each other. Alternatively, the first driving head of the image forming apparatus is made of a magnetic material, and the magnetic 1136 of the toner cartridge 10 is made of a magnetically attractable metal material, so that the first driving head of the image forming apparatus can attract the magnetic 1136 of the toner cartridge 10. Or, the first driving head of the image forming apparatus is made of a magnetically attractable metal material, and the magnetic 1136 of the toner cartridge 10 is made of a magnetic material, so that the magnetic 1136 of the toner cartridge 10 can attract the first driving head of the image forming apparatus.

[0069] To ensure the toner in the toner cartridge 112 is in a loose and flowing state, the toner cartridge 10 in this embodiment further includes a second driven head 1125, a transmission gear 1124, a driven gear 1123, and a stirring frame 1121. The second driven head 1125 is rotatably supported at the rear end of the toner cartridge housing 11 and is used to dock with the second drive head of the image forming apparatus to receive the rotational driving force of the second drive head. The stirring frame 1121 is rotatably supported in the toner cartridge 112 and is provided with a stirring scraper 1122. The extended end of the stirring frame 1121 extends out of the rear end of the toner cartridge 112 and is fitted with the driven gear 1123. The transmission gear 1124 is rotatably supported at the rear end of the toner cartridge housing 11 and meshes between the driven gear 1123 and the drive gear 11251 of the second driven head 1125.

[0070] After the toner cartridge 10 is installed in the predetermined position of the image forming apparatus in this embodiment, the second drive head of the image forming apparatus engages with the second driven head 1125 of the toner cartridge 10 in this embodiment. As the second drive head of the image forming apparatus rotates, it drives the second driven head 1125 to rotate. Since the transmission gear 1124 meshes between the driven gear 1123 and the drive gear 11251 of the second driven head 1125, the drive gear 11251 of the second driven head 1125 synchronously drives the transmission gear 1124 to rotate. The transmission gear 1124 synchronously drives the driven gear 1123, which is sleeved on the extended end of the stirring frame 1121, to rotate. This synchronously drives the stirring frame 1121 to drive the stirring scraper 1122 to rotate. The rotating stirring scraper 1122 can agitate the toner in the toner compartment 112 of the toner cartridge 10 to a loose and flowing state, so as to thoroughly discharge the toner in the toner compartment 112 to the toner discharge chamber 113 for discharge, avoiding toner residue and waste.

[0071] Specifically, in this embodiment, the stirring scraper 1122 is a soft rubber elastic sheet, which gives the stirring scraper 1122 excellent flexibility and elastic deformation ability, thereby improving the stirring ability of the stirring scraper 1122 to agitate the toner. Moreover, the outer end of the stirring scraper 1122, which is a soft rubber elastic sheet, abuts against the cavity wall of the toner hopper cavity 112, thereby thoroughly agitating the toner in the toner hopper cavity 112 and avoiding waste caused by residual toner on the cavity wall of the toner hopper cavity 112.

[0072] Combination Figures 3 to 12 In this embodiment, the toner cartridge 10 also includes a waste toner compartment shell 13, a movable cover 133, and a tension spring 134. The waste toner compartment shell 13 is located at the front end of the toner compartment shell 11. The waste toner chamber 132 of the waste toner compartment shell 13 is used to contain waste toner, and the rear end of the waste toner compartment shell 13 is provided with a toner inlet 131 that communicates with the waste toner chamber 132. The tension spring 134 is connected between the movable cover 133 and the waste toner compartment shell 13 to force the movable cover 133 to close the toner inlet 131. The waste toner conveying part 20 of the image forming apparatus is used to insert into the toner inlet 131 and push open the movable cover 133 to convey the waste toner discharged by the image forming apparatus into the waste toner chamber 132.

[0073] Combination Figure 13 In this embodiment, the toner cartridge 10 is installed at a predetermined position of the image forming apparatus. The waste toner conveying section 20 of the image forming apparatus is inserted into the toner inlet 131 and pushes open the movable cover 133, so that the movable cover 133 moves away from the toner inlet 131 to open the toner inlet 131, so that the waste toner discharged by the image forming apparatus is conveyed through the waste toner conveying section 20 of the image forming apparatus to the waste toner chamber 132 of the toner cartridge 10. At this time, the tension spring 134 is in a stretched state.

[0074] Combination Figure 12 In this embodiment, after the toner cartridge 10 is completely removed from the image forming apparatus, the restoring elastic force of the tension spring 134 forces the movable cover 133 to move toward the toner inlet 131 to close the toner inlet 131, thereby preventing waste toner leakage from the waste toner chamber 132.

[0075] To further improve the sealing performance of the powder inlet 131, a sealing gasket 135 is provided on the end face of the movable cover 133 near the powder inlet 131 in this embodiment. The sealing gasket 135 is used to seal the powder inlet 131. Specifically, the sealing gasket 135 in this embodiment is made of an elastic sealing material.

[0076] To improve the stability of the movable cover 133, in this embodiment, an outer ring sleeve 1331 is provided protruding from one end of the movable cover 133 near the powder inlet 131, and a support sleeve 1311 is provided protruding from the powder inlet 131 toward the movable cover 133. The outer ring sleeve 1331 is movably fitted around the outer periphery of the support sleeve 1311, and a slider 1332 is provided on the inner peripheral wall of the outer ring sleeve 1331. A rail groove 1312 is provided on the outer peripheral wall of the support sleeve 1311. The rail groove 1312 extends axially in the powder inlet 131, and the slider 1332 is movably located in the rail groove 1312. The rail groove 1312 plays a positioning and guiding role for the movement of the slider 1332, thereby improving the stability of the movable cover 133's movement.

[0077] To prevent waste powder from accumulating at the powder inlet 131 and to move the waste powder in the waste powder chamber 132, the toner cartridge 10 in this embodiment also includes a swing plate 136 located in the waste powder chamber 132. The waste powder chamber 132 is provided with a support shaft 1321 extending in the front-to-back direction. The middle part of the swing plate 136 is rotatably sleeved on the support shaft 1321. The first end plate 1361 of the swing plate 136 is located directly below the powder inlet 131. The waste powder chamber 132 is provided with a first limiting rod 1322 and a second limiting rod 1323. The first limiting rod 1322 is located below the support shaft 1321, and the second limiting rod 1323 is located below the first limiting rod 1322. The second end plate 1362 of the swing plate 136 is located between the first limiting rod 1322 and the second limiting rod 1323.

[0078] Thus, the waste toner discharged from the image forming apparatus is conveyed to the toner inlet 131 through the waste toner conveying section 20 of the image forming apparatus. The waste toner entering the waste toner chamber 132 from the toner inlet 131 falls onto the first end plate 1361 of the swing plate 136 directly below the toner inlet 131. Since the middle part of the swing plate 136 is rotatably sleeved on the support shaft 1321 inside the waste toner chamber 132, and the second end plate 1362 of the swing plate 136 is located between the first limiting rod 1322 and the second limiting rod 1323, the first end plate 1361 of the swing plate 136 rotates relative to the support shaft 1321 under the gravity of the falling waste toner, so that the second end plate 1362 of the swing plate 136 swings between the first limiting rod 1322 and the second limiting rod 1323 to move the waste toner accumulated in the waste toner chamber 132. In this embodiment, the swing plate 136 of the toner cartridge 10 does not require a power source to drive it, and the structure is simple, thus saving production costs.

[0079] In order to further improve the rotational sensitivity of the swing plate 136 to move the waste powder accumulated in the waste powder cavity 132, the first end plate 1361 of the swing plate 136 in this embodiment is provided with at least one first through groove 13611, and the second end plate 1362 of the swing plate 136 in this embodiment is provided with at least one second through groove 13621.

[0080] In addition, the toner cartridge 10 in this embodiment also includes a second spring 138 and a handle 137. The handle 137 is movably disposed at the upper front end of the waste toner container 13. The front end of the waste toner container 13 is provided with a second sliding groove 1391, which extends in the vertical direction. The handle 137 is provided with a second sliding buckle 1372, which is movably located within the second sliding groove 1391. The second spring 138 presses against the handle 137 and the waste toner container 13 to force the handle 137 to move upward away from the waste toner container 13, so that the upper end protrusion 1371 of the handle 137 extends out of the upper end of the waste toner container 13 and is used to hook onto the locking structure of the image forming apparatus.

[0081] Therefore, during the installation of the toner cartridge 10 into the image forming apparatus in this embodiment, the operator presses down on the upper end face of the handle 137 of the toner cartridge 10, causing the upper protrusion 1371 of the handle 137 to move downward and retract inward, preventing the upper protrusion 1371 of the handle 137 from protruding out of the waste toner compartment shell 13 and causing installation obstruction, so that the toner cartridge 10 can be smoothly installed into the image forming apparatus. At this time, the second spring 138 pressing between the handle 137 and the waste toner compartment shell 13 is in a compressed state.

[0082] When the toner cartridge 10 of this embodiment is installed in the predetermined position of the image forming apparatus, the operator releases the handle 137 of the toner cartridge 10. The second spring 138 then elastically recovers from the compressed state. Under the elastic restoring force of the second spring 138, the handle 137 is forced to move upward away from the waste toner compartment 13, so that the upper end protrusion 1371 of the handle 137 extends out of the upper end of the waste toner compartment 13 and is used to hook onto the locking structure of the image forming apparatus, so as to stably lock the toner cartridge 10 in the image forming apparatus for supplying toner.

[0083] Since the second sliding buckle 1372 of the handle 137 of the toner cartridge 10 in this embodiment is movably located in the second sliding groove 1391 of the waste toner hopper shell 13, the up and down movement of the handle 137 is stable and reliable, thereby improving the installation stability and reliability of the toner cartridge 10.

[0084] To further improve the smoothness and reliability of the up-and-down movement of the handle 137, the waste powder hopper shell 13 in this embodiment is provided with a first sleeve 1393, and the handle 137 is provided with a first positioning post 1373. The first positioning post 1373 is inserted into the first sleeve 1393 in a vertical direction. The upper end of the second spring 138 is sleeved on the first positioning post 1373, and the lower end of the second spring 138 is located inside the first sleeve 1393, thereby ensuring the working stability of the second spring 138 and improving the stability and reliability of the up-and-down movement of the handle 137.

[0085] To further improve the smoothness and reliability of the up-and-down movement of the handle 137, the waste powder hopper shell 13 in this embodiment is provided with a second sleeve 1392, and the handle 137 is provided with a second positioning post 1374. The second positioning post 1374 is movably inserted into the second sleeve 1392 in the up-and-down direction. The second sleeve 1392 plays a positioning and guiding role for the second positioning post 1374, thereby further improving the stability and reliability of the up-and-down movement of the handle 137.

[0086] To ensure the stability of the upper surface of the handle 137 of the toner cartridge 10 when pressed down by the operator, an anti-slip protrusion 1375 is provided on the upper surface of the handle 137 in this embodiment. Furthermore, a hand-holding groove 1394 is recessed in the front end face of the waste toner hopper shell 13 in this embodiment, so that the operator's hand can be engaged in the hand-holding groove 1394 and pressed down on the upper surface of the handle 137 of the toner cartridge 10.

[0087] Furthermore, in this embodiment, the toner cartridge 10 also includes a rear end cover 116. The rear end cover 116 is detachably fitted onto the rear end of the toner cartridge housing 11 and forms a receiving cavity between the rear end of the toner cartridge housing 11 and the rear end of the toner cartridge housing 11. The drive gear 11251, the transmission gear 1124, and the driven gear 1123 are all located within this receiving cavity. The rear end cover 116 has a first clearance hole 1161 and a second clearance hole 1162 through it. The first clearance hole 1161 is correspondingly provided with the first driven head 1134, and the second clearance hole 1162 is correspondingly provided with the second driven head 1125. Moreover, in this embodiment, the rear end of the toner cartridge housing 11 has a toner filling port 114 through it, which communicates with the toner cartridge cavity 112. A sealing cover is detachably installed at the toner filling port 114. Therefore, when the toner in the toner compartment 112 of the toner cartridge 10 is used up, the rear cover 116 can be removed from the toner compartment housing 11, and the sealing cover installed at the toner filling port 114 can be removed, so that toner can be added to the toner compartment 112 of the toner compartment housing 11 through the toner filling port 114. After the toner is replenished, the sealing cover is installed at the toner filling port 114 to seal the toner filling port 114, and the rear cover 116 is installed at the rear end of the toner compartment housing 11, so as to facilitate the recycling and reuse of the toner cartridge 10 and save energy.

[0088] The above embodiments are merely preferred examples of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles of the present invention in accordance with the claims of the present invention should be included in the scope of the present invention patent application.

The handle is provided with a second sliding buckle that is movably located within the second sliding groove. The second spring presses against the handle and the waste toner compartment housing to force the handle to move upward away from the waste toner compartment housing, so that the upper end of the handle protrudes out of the upper end of the waste toner compartment housing and is used to hook onto the locking structure of the image forming apparatus.
