Description

Technical Field

[0001] The invention relates to the field of electronic imaging equipment consumables, in particular to a carbon powder cartridge. Background Art

[0002] The electrophotographic imaging device is equipped with a removable toner cartridge, which contains a developer (toner) such as toner, for developing the electrostatic latent image formed on the image processing unit to form a visible image on a medium such as paper. Since the developer is a consumable, it needs to be constantly replenished in the electrophotographic imaging device, and the developer unit removably installed in the electrophotographic imaging device can often only load a certain amount of developer, so the toner cartridge needs to be replaced frequently.

[0003] Chinese invention patent application with publication number CN106019897A discloses a toner cartridge and developer supply system, which uses an inclined portion (combining portion 3b2) to directly guide the combining portion 11b to move vertically upward, and then open the developer receiving port 11a (powder inlet) on the printing device.

[0004] However, since the toner cartridge needs to be replaced frequently, the coupling part 11b needs to frequently rub against different inclined parts, which may cause surface wear of the coupling part 11b, reduce the size of the coupling part 11b, or even cause the coupling part 11b to be broken, resulting in poor coupling between the powder inlet on the printing device and the powder outlet on the toner cartridge, and further causing developer leakage or the inability to open the powder inlet, thereby causing the electronic photographic imaging device to fail to print normally.

[0005] In addition, since the guide rails (joint portion 3b2) are provided on both sides of the toner cartridge, once the toner cartridge is tilted or the two sliding protrusions in the cartridge receiving chamber that cooperate with the guide rails are not at the same horizontal position during installation, the sliding protrusions may get stuck with the guide rails of the toner cartridge, and the toner cartridge cannot be smoothly installed in the electronic photographic imaging device. In addition, the powder discharge port of the existing toner cartridge is rigidly connected to the powder inlet of the cartridge receiving chamber, which will affect the sealing and positioning of the powder outlet. Summary of the invention

[0006] The object of the present invention is to provide a toner cartridge with a simple structure and a smooth assembly process, while preventing the toner receiving member in an electronic photographic imaging device from being unable to open a toner inlet due to wear of the guide rail.

[0007] To achieve the above-mentioned purpose, the present invention provides a toner cartridge, which can be detachably installed in an electronic photographic imaging device. The electronic photographic imaging device includes a powder cartridge receiving shell and a toner receiving member. The toner receiving member is located at the bottom of the powder cartridge receiving shell. The toner receiving member includes a main body and a powder inlet cover. The main body is provided with a powder inlet, and the powder inlet cover is arranged on the upper side of the powder inlet. The powder inlet cover is provided with a sealing part, a hinged part and a slide groove. The hinged part is hinged to the powder cartridge receiving shell, the sealing part is used to open and close the powder inlet, and the main body is provided with a sliding protrusion that cooperates with the slide groove; the sealing part and the slide groove are respectively located on both sides of the hinged part in the vertical direction. The toner cartridge comprises a cartridge body and an end cover, wherein the end cover is arranged at one end of the cartridge body, a powder discharge port which can be connected to the powder inlet is arranged at the bottom of the end cover, and a gate is arranged on the end cover, and the gate is used to open and close the powder discharge port; an unsealing protrusion is arranged on the bottom wall of the end cover, and the unsealing protrusion is arranged close to the powder discharge port, and both ends of the unsealing protrusion along the axial direction of the toner cartridge are provided with forced push inclined surfaces, and the forced push inclined surfaces are inclined downward; the toner cartridge is installed toward the electronic photographic imaging device along the axial direction of the cartridge body, and along with the installation operation of the toner cartridge, the forced push inclined surface pushes the powder inlet cover, and the powder inlet cover rotates around the hinge part and opens the powder inlet, and the powder inlet cover drives the main body to move toward the powder discharge port along the vertical direction.

[0008] It can be seen from the above scheme that when the toner cartridge is loaded into the electronic photographic imaging device, as the toner cartridge moves forward, the forced push inclined surface of the unsealing protrusion applies force to the powder inlet cover to open the powder inlet cover, and when the powder inlet cover rotates around the hinge, the sliding protrusion slides along the slide groove while pushing the main body of the toner receiving member upward to a position abutting against the gate to open the powder inlet of the electronic photographic imaging device, thereby realizing the engagement and connection between the powder discharge port of the toner cartridge and the powder inlet of the powder cartridge receiving chamber. In addition, since the toner cartridge of the present invention is not provided with a guide rail, it will not rub against the matching protrusion of the toner receiving member during installation and disassembly, which is conducive to avoiding wear of the toner receiving member, and avoiding the size reduction and breakage of the toner receiving member, and will not affect the normal docking of the powder inlet and the powder discharge port, and avoid the phenomenon of powder leakage or failure to open the powder inlet.

[0009] A preferred solution is that the bottom wall of the end cover is further provided with an elastic reset rod, the fixed end of the elastic reset rod is connected to the bottom wall of the end cover, and the unsealing protrusion is located at the free end of the elastic reset rod.

[0010] It can be seen from this that the setting of the elastic reset rod enables the elastic reset rod to drive the unsealing protrusion to move upward when the forced pushing inclined surface pushes the powder inlet cover on the upstream side of the installation direction, thereby avoiding the powder inlet cover on the upstream side; then the unsealing protrusion enters between the two powder inlet covers under the action of the elastic restoring force of the elastic reset rod, and continues to push the carbon powder cartridge, so that the forced pushing inclined surface abuts against the powder inlet cover on the downstream side and applies a force to the powder inlet cover, and the powder inlet cover rotates around the hinge part under the force.

[0011] A further solution is that a slot is vertically penetrated through the bottom wall of the end cover, and the elastic reset rod is located in the slot.

[0012] It can be seen that the arrangement of the slot facilitates the elastic deformation of the elastic reset rod.

[0013] A further solution is that a pressing block is arranged at a position where the gate and the unsealing protrusion are opposite in the vertical direction, the pressing block protrudes downward from the bottom wall of the gate, and the pressing block abuts against the free end of the elastic reset rod.

[0014] It can be seen that when the unsealing protrusion abuts against the powder inlet cover on the downstream side and applies force to the powder inlet cover, the pressing block limits the unsealing protrusion from the upper side of the unsealing protrusion to prevent the elastic reset rod from deforming so that the unsealing protrusion is upward and the powder inlet cover cannot be opened.

[0015] A further solution is that the pressing block is provided with a downwardly inclined guiding slope, and the guiding slope is located at the upstream side of the pressing block in the installation direction of the carbon powder cartridge.

[0016] It can be seen from this that interference between the pressing block and the free end of the elastic reset rod is avoided, ensuring that the unsealing protrusion smoothly enters under the pressing block.

[0017] A preferred solution is that the bottom wall of the end cover is also provided with a stop protrusion, which is located on the upstream side of the unsealing protrusion in the installation direction of the carbon powder cartridge; a receiving groove is formed between the stop protrusion and the unsealing protrusion, and a part of the powder inlet cover can extend into the receiving groove; the stop protrusion is arranged to be inclined downward away from the side wall of the unsealing protrusion.

[0018] It can be seen that the setting of the stop protrusion can ensure that the powder inlet cover can be rotated and maintained in the extreme open position. At the same time, due to the setting of the stop protrusion, the size requirement of the unsealing protrusion is reduced. The unsealing protrusion only needs to force the powder inlet cover to flip toward the extreme open position, and there is no need to abut against the powder inlet cover all the time. The stop protrusion is mainly relied on to ensure that the powder inlet cover is flipped to the extreme position, which can make the process of opening the powder inlet cover smoother.

[0019] A preferred solution is that at least one of the two opposite sides of the end cover is provided with an unsealing guide rail, and the unsealing guide rail is provided with a guide slope, which is inclined relative to the central axis of the cylinder body; a driving force receiving part is provided on the outer surface of the end of the cylinder body close to the end cover, and the guide slope is inclined from bottom to top along the axial direction of the cylinder body, from the end away from the driving force receiving part to the end close to the driving force receiving part; the toner receiving part also includes two support rods and two matching protrusions, the two support rods are relatively arranged on both sides of the main body, the matching protrusions are arranged one-to-one with the support rods, and the matching protrusions are arranged on the opposite side walls of the two support rods and slidingly matched with the guide slopes.

[0020] It can be seen that the provision of the unsealing guide rail further ensures the smooth opening of the powder inlet cover and the docking of the powder inlet of the main body and the powder discharge port of the carbon powder cartridge.

[0021] A preferred solution is that the gate includes a plate body and an elastic seal, the elastic seal is located on a side of the plate body facing the toner receiving member and arranged opposite to the toner receiving member, or the elastic seal is located on a side of the plate body facing away from the toner receiving member.

[0022] It can be seen that after the main body of the toner receiving member is docked with the powder discharge port, the contact between the toner receiving member and the gate is a flexible contact. Therefore, the position of the toner receiving member is easier to control. For example, when the toner receiving member is pulled to a higher position by the guide rail, the elastic seal is compressed to a greater extent, and when the toner receiving member is pulled to a lower position by the guide rail, the elastic seal is compressed to a lesser extent. Since the elastic seal can be elastically deformed when subjected to force, even if the toner receiving member is tilted, the setting of the elastic seal enables the gate to adapt to the state change of the toner receiving member and always dock well with the toner receiving member. The toner receiving member and the powder discharge port can maintain a good sealing state to prevent toner from leaking from the docking position. At the same time, due to the setting of the elastic seal, the toner receiving member can be more stably supported at the combined position with the powder discharge port. When the elastic seal is located between the plate body and the end cover, when the toner receiving element is tilted, a force will be applied to the plate body. Since an elastic seal is arranged between the plate body and the end cover, the plate body can follow the position change of the toner receiving element, thereby always maintaining a tight connection with the toner receiving element.

[0023] A preferred solution is that the end cover includes an outer cover and a shell, the outer cover is arranged outside the shell, the powder discharge port is located on the shell, the gate is detachably mounted on the shell, the shell is provided with a gate slide groove extending along the axial direction of the barrel body, and the gate slide groove is slidably matched.

[0024] It can be seen that when the toner cartridge is installed, the gate is stuck in the electronic photographic imaging device, and the toner cartridge continues to be pushed forward, the gate slides relative to the slide slot, and the toner discharge port opens.

[0025] A further solution is that both opposite sides of the shell are provided with limit rails, the limit rails protrude outward from the side wall of the shell and extend along the axial direction of the cartridge body. A limit slot is provided in the powder cartridge receiving shell, and the limit rails are slidably matched with the limit slot.

[0026] It can be seen that the cooperation between the limiting guide rail and the slide groove ensures that the toner cartridge can be inserted into the electronic photographic imaging device along the horizontal direction. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the toner cartridge 2 is detachably installed in the powder cartridge receiving chamber 11. The toner receiving member 12 is arranged at the bottom of the powder cartridge receiving chamber 11. After the toner cartridge 2 is installed in place, the toner receiving member 12 and the powder discharge port 40 ( Figure 5 For ease of description, the installation direction of the toner cartridge is referred to as the "front-rear direction" hereinafter, and the downstream side of the installation direction is defined as the front side, and the direction perpendicular to the front-rear direction and perpendicular to the vertical direction is referred to as the "left-right direction".

[0055] like Figure 2 and Fig.12As shown, the toner receiving member 12 includes an inner sleeve 120, an outer sleeve 125, a spring 126 and two powder inlet covers 13, and the outer sleeve 125 includes a cylindrical portion 121, two support rods 122 and two matching protrusions 123, as shown in FIG. Figure 2 As shown, two support rods 122 are relatively arranged on the left and right sides of the cylindrical part 121, and the matching protrusions 123 are arranged one by one with the support rods 122. The matching protrusions 123 are arranged on the opposite side walls of the two support rods 122. The inner sleeve 120 includes a main body 1201 and a connecting part 1202. The main body 1201 is provided with a powder inlet 124 ( Fig.13 As shown in the figure, the connecting portion 1202 is cylindrical and is arranged on the outer peripheral wall of the main body 1201. The connecting portion 1202 and the main body 1201 are coaxially arranged. A mounting groove 1203 is formed between the connecting portion 1202 and the main body 1201. The inner sleeve 120 is installed in the cylindrical portion 121 of the outer sleeve 125. The spring 126 is sleeved outside the main body 1201 and is located in the mounting groove 1203. The two ends of the spring 126 are respectively abutted against the inner sleeve 120 and the outer sleeve 125. The inner sleeve 120 can move in the vertical direction relative to the outer sleeve 125.

[0056] Two powder inlet covers 13 are arranged on the upper side of the powder inlet 124 along the front-to-back direction to open and close the powder inlet 124. Each powder inlet cover 13 is provided with a sealing portion 131, two hinged portions 132, a slide groove 133 and two force-bearing portions 136. The sealing portion 131 covers the top of the powder inlet 124. The sealing portions 131 of the two powder inlet covers 13 are butted along the front-to-back direction to achieve sealing of the powder inlet 124. The two force-bearing portions 136 are both located at the top of the powder inlet cover 13 and are respectively located on the left and right sides of the sealing portion 131. The two hinged portions 132 are respectively located on the left and right sides of the powder inlet cover 13, and the two hinged portions 132 are both hinged to the powder cartridge receiving shell 10. The powder inlet cover 13 can rotate around the hinged portion 132 to open the powder inlet 124. The two slide grooves 133 are respectively located on the left and right sides of the main body 1201 of the carbon powder receiving member 12, the slide groove 133 of the powder inlet cover 13 located on the front side is located on its left side wall 134, and the slide groove 133 of the powder inlet cover 13 located on the rear side is located on its right side wall 135, and the left and right sides of the main body 1201 are respectively provided with sliding protrusions 1211 that cooperate with the two slide grooves 133. When the powder inlet cover 13 is in the closed position, the two slide grooves 133 extend along the front and rear directions, the sealing part 131 is located on the upper side of the hinged part 132, and the slide groove 133 is located on the lower side of the hinged part 132.

[0057] See also Figure 3The toner cartridge 2 includes a cartridge body 3 and an end cap 4. The cartridge body 3 extends in the front-rear direction. An opening 31 is provided at one end of the cartridge body 3. The end cap 4 is mounted at the open end of the cartridge body 3. A stirring rack 33 is fixed in the open end of the cartridge body 3. When the cartridge body 3 rotates, the stirring rack 33 will rotate synchronously with the cartridge body 3 to transfer the toner in the open end of the cartridge body 3 to the end cap 4. The outer surface of the cartridge body 3 near the open end is provided with teeth 34 of a driving force receiving portion. The teeth 34 can receive the driving force output by the driving component of the electronic photographic imaging device. For example, the driving component is a gear, which is meshed with the teeth 34. When the gear rotates, the teeth 34 are driven to rotate, thereby driving the cartridge body 3 to rotate.

[0058] See also Figures 3 to 6 The end cover 4 includes an outer cover 5 and a shell 6. The outer cover 5 is arranged outside the shell 6. The bottom wall of the shell 6 is vertically penetrated with a powder discharge port 40 and two slots 60. The powder discharge port 40 is connected to the inside of the shell 6. The slots 60 are located on the left and right sides of the powder discharge port 40 and are located outside the shell 6. Elastic reset rods 62 are arranged in the two slots 60. The fixed end 621 of the elastic reset rod 62 is connected to the side wall of the slot 60. The lower side of the free end 622 of the elastic reset rod 62 is provided with an unsealing protrusion 63. The unsealing protrusion 63 protrudes downward from the bottom wall of the shell 6. The two unsealing protrusions 63 are arranged opposite to each other in the left and right directions. The free end of the elastic reset rod 62 located on the left side of the shell 6 is also provided with a stop protrusion 64. The stop protrusion 64 is located on the rear side of the unsealing protrusion 63. A receiving groove 65 is formed between the stop protrusion 64 and the unsealing protrusion 63, as shown in FIG. Fig.18 As shown, when the powder inlet cover 13 is in the open state, the limiting protrusion 1341 of the left side wall 134 of the powder inlet cover 13 extends into the accommodating groove 65 and the limiting protrusion 1341 is adjacent to the stop protrusion 64 in the front-to-back direction. The limiting protrusion 1341 cooperates with the stop protrusion 64 to limit the powder inlet cover 13 in the front-to-back direction and prevent the powder inlet cover 13 from rotating in the opposite direction. At this time, the stop protrusion 64 is opposite to the slide groove 133 in the vertical direction.

[0059] The unsealing protrusion 63 and the stop protrusion 64 are both arranged near the powder discharge port 40. The cross section of the unsealing protrusion 63 is roughly triangular, and the unsealing protrusion 63 is provided with a forced push slope 631 on both the front and rear sides. The forced push slope 631 is parallel to the left and right direction, and the forced push slope 631 is inclined downward. The cross section of the stop protrusion 64 is roughly a right-angled trapezoid, and the side wall 642 of the stop protrusion 64 facing the unsealing protrusion 63 is roughly parallel to the vertical direction. In other embodiments, the side wall 642 can also be inclined at a small angle to the vertical direction to cooperate with the limiting protrusion 1341 of the powder inlet cover 13 to stop the powder inlet cover 13. The side wall 641 of the stop protrusion 64 away from the unsealing protrusion 63 is parallel to the left and right direction and inclined downward, so that the carbon powder cartridge 2 can be smoothly taken out of the powder cartridge receiving shell 10. Fig.11 As shown, the maximum distance l1 between the stop protrusion 64 and the bottom wall of the housing 6 is smaller than the maximum distance l2 between the unsealing protrusion 63 and the bottom wall of the housing 6, and the distance l3 between the powder inlet cover 13 and the bottom wall of the housing 6 on the moving path of the unsealing protrusion 63 is larger than the maximum distance l1 between the stop protrusion 64 and the bottom wall of the housing 6, and smaller than the maximum distance l2 between the unsealing protrusion 63 and the bottom wall of the housing 6. In this way, during the installation of the toner cartridge 2, the side wall 642 of the stop protrusion 64 can be prevented from interfering with the powder inlet cover 13.

[0060] like Figure 5 and 6 As shown, limit guide rails 67 are provided on both sides of the shell 6. The two limit guide rails 67 protrude outward from the left and right walls of the shell 6 respectively and extend along the axial direction of the barrel body 3. A limit slide groove 14 is provided in the powder cartridge receiving shell 10. The limit guide rails 67 are slidably matched with the limit slide groove 14. The limit guide rails 67 and the limit slide groove 14 are matched to limit in the vertical direction, ensuring that the toner cartridge 2 can be installed in the electronic photographic imaging device along the horizontal direction, thereby ensuring the stable connection between the toner receiving component 12 and the toner cartridge 2.

[0061] See also Figure 7 , 8 and 12, the shell 6 is detachably mounted with a gate 7, a powder outlet 71 is provided on the gate 7, the shell 6 is provided with a gate slide 61 extending along the axial direction of the barrel body 3, the gate 7 and the gate slide 61 slide to open or close the powder outlet 40, connecting rods 74 are provided on both sides of the gate 7, and a buckle 72 is provided at the free end of the connecting rod 74.

[0062] The gate 7 includes a plate body 70 and a first elastic seal 73. A seal installation groove 66 is provided at the bottom of the housing 6. The powder discharge port 40 is located in the seal installation groove 66. A second elastic seal 661 is provided in the seal installation groove 66. The second elastic seal 661 is provided with a connecting port 662 communicating with the powder discharge port 40, and the connecting port 662 is arranged opposite to the powder discharge port 40 in the vertical direction. The first elastic seal 73 and the second elastic seal 661 are respectively arranged on opposite sides of the plate body 70. The second elastic seal 661 is located on the side of the plate body 70 facing the inside of the housing 6, and is used to achieve sealing between the housing 6 and the gate 7. The first elastic seal 73 is located on the side of the plate body 70 facing the toner receiving member 12 and is arranged opposite to the main body 1201 of the toner receiving member 12 in the vertical direction, so that when the toner receiving member 12 moves upward to the position engaged with the powder discharge port 40, it can elastically abut against the gate 7. The powder outlet 71 of the gate 7 penetrates the plate body 70 and the first elastic seal 73 in the vertical direction. When the gate 7 is in the open position, the powder outlet 40 on the shell 6 and the connecting port 662 of the second elastic seal 661 are opposite to and connected with the powder outlet 71 on the gate 7 in the vertical direction.

[0063] A pressing block 75 is provided on the plate body 70 of the gate 7. The pressing block 75 protrudes downward from the bottom wall of the plate body 70. The pressing block 75 is provided at the fixed end of the connecting rod 74. A downwardly inclined guiding slope 751 is provided on the rear side of the pressing block 75. During the opening process of the powder inlet cover 13, the pressing block 75 abuts against the free end 622 of the elastic reset rod 62. In this way, when the free end 622 of the elastic reset rod 62 tends to deform upward, the pressing block 75 can apply a downward force to the unsealing protrusion 63, thereby ensuring that the powder inlet cover 13 can be opened by the unsealing protrusion 63.

[0064] See also Figures 9 to 18 The installation process of the toner cartridge 2 is as follows, wherein the direction indicated by the arrow is the installation direction of the toner cartridge 2 .

[0065] After the toner cartridge 2 is loaded into the powder cartridge receiving chamber 11 of the electronic photographic imaging device, the buckle 72 of the gate 7 is locked and fixed, and the cartridge body 3 is continuously pushed forward, and the forced pushing inclined surface 631 on the front side of the unsealing protrusion 63 abuts against the powder inlet cover 13 on the rear side. Since the powder inlet cover 13 is at the extreme closed position at this time and cannot be rotated around the hinge 132 in the clockwise direction, the unsealing protrusion 63 is stressed so that the free end 622 of the elastic reset rod 62 is deformed upward, passes through the upper side of the powder inlet cover 13 on the rear side, and enters between the two powder inlet covers 13 under the action of the elastic restoring force of the elastic reset member 62, as shown in FIG. Figures 9 to 12 As shown, the barrel body 3 is continuously pushed, and the forced push inclined surface 631 on the front side of the unsealing protrusion 63 contacts the powder inlet cover 13 on the front side.

[0066] like Figures 13 to 15As shown, the barrel body 3 is continuously pushed, and the forced push inclined surface 631 on the front side of the unsealing protrusion 63 forces the front powder inlet cover 13, so that the powder inlet cover 13 rotates around the hinge 132. Due to the cooperation between the sliding protrusion 1211 of the main body 1201 and the slide groove 133 of the powder inlet cover 13, the powder inlet cover 13 rotates around the hinge 132 while applying a force to the main body 1201, driving the main body 1201 to move upward. At the same time, the limiting protrusion 1341 on the left side wall 134 of the powder inlet cover 13 enters the receiving groove 65, and while the main body 1201 moves upward, it will apply a force to the rear powder inlet cover 13, so that the rear powder inlet cover rotates around its own hinge 132 at the same time.

[0067] like Figures 16 to 18 As shown, the cartridge body 3 is pushed continuously, and the powder inlet cover 13 rotates 90 degrees to a fully open position, and the stop protrusion 64 cooperates with the limiting protrusion 1341 to prevent the powder inlet cover 13 from rotating in the opposite direction. The powder inlet cover 13 drives the main body 1201 to move toward the powder discharge port 40 along the vertical direction to a position where the main body 1201 abuts against the first elastic sealing member 73 of the gate 7, and the powder discharge port 40 of the toner cartridge 2 is connected with the powder inlet 124 of the powder cartridge receiving chamber 11.

[0068] When the toner cartridge 2 is taken out of the electrophotographic image forming apparatus, the toner cartridge is moved along the Fig.17 Movement in the reverse direction indicated by the middle arrow, first, the side wall 641 of the stop protrusion 64 and the forced push slope 631 on the rear side of the unsealing protrusion 63 both apply force to the front powder inlet cover 13 to rotate the front powder inlet cover 13 to the closed position, and at the same time, the inner wall of the slide groove 133 on the powder inlet cover 13 applies force to the sliding protrusion 1211 to move the inner sleeve 120 and the outer sleeve 125 downward.

[0069] Carbon powder cartridge second embodiment:

[0070] As an explanation of the second embodiment of the toner cartridge of the present invention, only the differences from the first embodiment of the toner cartridge described above will be explained below.

[0071] See also Fig.19, only one of the left and right sides of the housing 26 is provided with an unsealing guide rail 262, which is located on the first side wall 2623 of the housing 26 and protrudes outward from the first side wall 2623, and is provided with a guide slope 2621, which is inclined relative to the central axis of the barrel body 3. Along the axial direction of the barrel body 23, from the end away from the teeth 234 to the end close to the teeth 234, the guide slope 2621 is inclined from bottom to top. A longitudinal plane perpendicular to the central axis of the barrel body 23 and passing through the powder discharge port intersects with the guide slope 2621, and the end of the guide slope 2621 close to the teeth 234 is higher than the intersection of the longitudinal plane and the guide slope 2621. The mating protrusion of the toner receiving member moves along the guide slope 2621 to force the toner receiving member to move in the vertical direction so that the powder inlet cover opens or closes the powder inlet. When the mating protrusion moves upward along the guiding slope 2621, the outer sleeve drives the inner sleeve to move upward, and the slide groove part of the powder inlet cover is forced to rotate around the hinge part after being subjected to force, so that the powder inlet cover is opened, and at the same time, the inner sleeve moves upward to a position abutting against the elastic seal 273 of the gate 27, and the powder discharge port of the carbon powder cartridge 22 is connected with the powder inlet of the powder cartridge receiving chamber. The synergistic effect of the unsealing guide rail 262 and the unsealing protrusion 263 further ensures the smooth opening and closing of the powder inlet.

The stop surface 3632 and the support surface 3631 are smoothly transitionally connected through the arc surface 3633.

[0075] The setting of the stop surface 3632 prevents the mating protrusion 123 on the same side from entering the lower side of the support surface 3631 , but moves onto the support surface 3631 under the action of the arc surface 3633 connecting the stop surface 3632 and the support surface 3631 , so as to achieve the positioning of the toner receiving component 12 .

[0079] Carbon powder cartridge fifth embodiment:

[0080] As an explanation of the fifth embodiment of the toner cartridge of the present invention, only the differences from the second embodiment of the toner cartridge described above will be explained below.

[0081] See also Fig.24 and 25 In this embodiment, the gate 17 includes a plate body 170 and an elastic seal 173. The elastic seal 173 and the elastic seal 174 are both located on the side of the plate body 170 facing away from the toner receiving member. A mounting groove 171 is provided on the side wall of the plate body 170 facing away from the toner receiving member. An opening 172 is provided at the bottom of the mounting groove 171. The opening 172 passes through the plate body 170 in the vertical direction. The elastic seal 173 is installed in the mounting groove 171, and the elastic seal 173 is located between the elastic seal 174 and the bottom wall 1711 of the mounting groove 171.

[0082] The elastic sealing member 173 includes a movable member 1731 and a sealing ring 1732. The sealing ring 1732 is arranged on the side of the movable member 1731 facing away from the toner receiving member. The movable member 1731 includes a main body 17311 and a limiting portion 17312. The limiting portion 17312 protrudes outward from the side wall of the main body 17311. The limiting portion 17312 is adjacent to the bottom wall of the mounting groove 171. The limiting portion 17312 cooperates with the bottom wall 1711 of the mounting groove 171 to limit the movable member 1731 in the vertical direction. The main body 17311 extends downward into the opening 172. A docking groove 17313 is provided on the lower side of the main body 17311. The toner receiving member extends into the docking groove 17313 to engage with the movable member 1731, thereby achieving docking of the toner receiving member with the toner discharge port 140. A powder outlet hole 17314 is vertically penetrated through the main body 17311 . The powder outlet hole 17314 and the center hole 17321 of the sealing ring 1732 form a powder outlet port 1071 of the gate 17 . The size of the powder outlet hole 17314 is larger than that of the center hole 17321 .

[0083] In addition, the structures of the elastic sealing member 173 and the plate body 170 in this embodiment can also be applied to the first to fourth embodiments of the toner cartridge.

[0084] It can be seen from the above that when the carbon powder receiving part is tilted, a force will be applied to the movable part, and only the elastic sealing part and the carbon powder receiving part will be adaptively adjusted in position, and the overall position of the gate will not be changed, which can achieve a better sealing effect.

[0085] Other embodiments of carbon powder cartridge:

[0086] The cross section of the unsealing protrusion may also be trapezoidal or irregular in shape, and the two forced-pushing inclined surfaces are respectively located at the front and rear sides of the unsealing protrusion.

[0087] The length and inclination angle of the unsealing guide rail can be adjusted as needed.

[0088] The stop protrusion may not be provided, and the powder inlet cover may be positioned in the open position by increasing the size of the unsealing protrusion.

[0089] The elastic reset rod and the slot can be eliminated, and the unsealing protrusion can be arranged on the bottom wall of the shell, and the unsealing protrusion can be made of elastic material.

[0090] The stop surface and the support surface may also be arranged at a right angle. The stop surface and the support surface may also be arranged at an obtuse angle, and the inclination angle of the stop surface relative to the central axis of the cylinder body is greater than the inclination angle of the guide inclined surface relative to the central axis of the cylinder body, so that the matching protrusion usually does not contact the stop surface before it reaches the support surface, and the stop surface is used to prevent the matching protrusion from entering the lower side of the support surface and failing to play a supporting role.

[0091] The support member may also be a protrusion protruding outward from the side of the shell or outer cover and having a polygonal cross-section, and the stop surface and the support surface are two intersecting side walls on the support member, wherein the cross-section of the support member may be a polygon such as a triangle, rectangle, parallelogram or trapezoid, or other irregular shapes.

[0092] The unsealing guide rail can be a strip-shaped inclined protrusion, or a protrusion protruding outward from the side of the shell or outer cover and with a polygonal or irregular cross-section. The guiding slope can be a straight surface, or an arc surface, a serrated surface, a step surface, etc. When the guiding slope is a serrated surface or a step surface, the friction force is increased to play a role in stopping, preventing the toner receiving component from sliding downward under the action of its own gravity, thereby improving the stability of the positioning of the toner receiving component.

[0093] The support surface can be a smooth surface or a rough surface, for example, the support surface has protrusions or serrations that can increase the surface roughness, thereby playing a role of stopping and preventing the mating protrusion from sliding on the support surface after the mating protrusion is in place.

[0094] The sealing plate and the plate body of the gate can also be made of elastic material, so there is no need to provide additional elastic sealing parts.

[0095] The barrel body may be an integrated structure, and the driving force receiving part is arranged on the outer surface of the barrel body; the barrel body may also include a barrel section and a driving section arranged along the axial direction, the driving section is arranged at one end of the barrel section, the driving force receiving part is arranged on the outer surface of the driving section, the barrel section is fixed relative to the end cover, and the driving section rotates relative to the barrel section. The above changes can also achieve the purpose of the present invention.

[0096] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
