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] An electrophotographic imaging device generally has an image processing unit and a toner cartridge detachably mounted to the image processing unit. The toner cartridge contains a developer (toner) such as toner to develop 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 detachably mounted in the electrophotographic imaging device can often only load a certain amount of developer, so the toner cartridge needs to be replaced frequently.

[0003] There is a toner cartridge with guide rails on both sides. When the toner cartridge is installed in an electronic photographic imaging device, the guide rails cooperate with the powder cartridge receiving chamber in the electronic photographic imaging device as the toner cartridge moves, so that the powder cartridge receiving chamber moves toward the toner cartridge along the vertical direction, thereby realizing the engagement between the powder discharge port of the toner cartridge and the powder inlet of the powder cartridge receiving chamber. However, since the guide rails are provided on both sides of the toner cartridge, during the installation process, once the toner cartridge is tilted or the two sliding protrusions in the powder cartridge receiving chamber that cooperate with the guide rails are not in the same horizontal position, the sliding protrusions may be stuck with the guide rails of the toner cartridge, and the toner cartridge cannot be smoothly installed in the electronic photographic imaging device. At the same time, the powder discharge port of the existing toner cartridge and the powder inlet of the powder cartridge receiving chamber are rigidly connected, which will affect the sealing and positioning of the powder outlet.

[0004] In addition, the guide rail on the existing toner cartridge is arranged on the end cover, and the opening action of the powder discharge port is synchronous with the opening action of the powder inlet port, so when the powder inlet port is not connected with the powder discharge port, the opening of the powder discharge port may cause leakage of toner. Summary of the invention

[0005] The object of the present invention is to provide a toner cartridge which can prevent toner leakage.

[0006] 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 comprising a toner receiving member, the toner receiving member being provided with a powder inlet; the toner cartridge comprising a cartridge body and an end cover, the end cover being provided at one end of the cartridge body, the bottom of the end cover being provided with a powder discharge port which can be communicated with the powder inlet, the outer surface of one end of the cartridge body close to the end cover being provided with a driving force receiving portion, the end cover being provided with a gate; the gate comprising a sealing plate and a supporting plate, the sealing plate being used to open and close the powder discharge port, the supporting plate The support plate is connected to the edge of the sealing plate and is provided with an unsealing guide rail; the unsealing guide rail is provided with a guiding slope, which is inclined relative to the central axis of the barrel body, and is inclined from bottom to top along the axial direction of the barrel body, from the end away from the driving force receiving part to the end close to the driving force receiving part; a longitudinal plane perpendicular to the central axis of the barrel body and passing through the powder discharge port intersects with the unsealing guide rail; along with the installation operation of the toner cartridge, the guiding slope guides the toner receiving part to move toward the powder discharge port in the vertical direction until the toner receiving part is docked with the powder discharge port.

[0007] 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 mating protrusion of the toner receiving member moves upward along the guiding slope of the unsealing guide rail to open the powder inlet of the electronic photographic imaging device, and then the gate is engaged with the electronic photographic imaging device. At this time, the gate is still located at the position of closing the powder outlet, and then the cartridge body is pushed forward to open the powder outlet. Therefore, during the installation process of the toner cartridge, the powder inlet of the electronic photographic imaging device is opened first and then the powder outlet is opened. In this way, the powder outlet can be prevented from being opened before the powder inlet during the installation process, causing leakage of toner in the toner cartridge.

[0008] A preferred solution is that there are two support plates, the two support plates are respectively disposed on two opposite sides of the sealing plate, and the two support plates are arranged in parallel.

[0009] A further solution is that a support rail is provided on the support plate opposite to the unsealing rail, the support rail is provided with a first support surface, the first support surface extends along the axial direction of the cylinder body, and the longitudinal plane intersects with the first support surface.

[0010] It can be seen that, since the unsealing guide rail is only provided on one side of the toner cartridge, it can be avoided that the mating protrusions on both sides are not at the same horizontal position or the toner cartridge is tilted during installation, causing the toner cartridge to get stuck during installation.

[0011] In addition, when the toner cartridge is installed in place, the powder inlet of the electronic photographic imaging device is opened, the mating protrusion moves upward to the extreme position, and the mating protrusion on the side opposite to the unsealing guide rail is supported by the first supporting surface, thereby ensuring the stability of the positioning of the toner receiving component in the electronic photographic imaging device.

[0012] A further solution is that the support rail is further provided with a stop surface, and the stop surface extends from an end of the first support surface away from the driving force receiving portion to the lower side of the first support surface.

[0013] It can be seen that the stop surface is used to prevent the matching protrusion on the same side from moving to the lower side of the stop surface, thereby failing to achieve a supporting effect.

[0014] A preferred solution is that the stop surface and the first supporting surface are connected through an arc-shaped surface transition.

[0015] This shows that it is ensured that the matching protrusion can move smoothly above the first supporting surface.

[0016] A preferred solution is that both support plates are provided with unsealing guide rails.

[0017] A preferred solution is that the longitudinal plane intersects with the guiding inclined surface, and an end of the guiding inclined surface close to the driving force receiving portion is higher than the intersection position of the longitudinal plane and the guiding inclined surface.

[0018] It can be seen from this that it is ensured that the mating protrusion can move along the guiding slope to a position where the powder discharge port of the carbon powder cartridge can engage with the powder inlet of the powder cartridge receiving chamber, thereby preventing the mating protrusion from detaching from the unsealing guide rail due to insufficient length of the guiding slope.

[0019] A preferred solution is that the unsealing guide rail also includes a second supporting surface, the second supporting surface extends along the axial direction of the cylinder body, the second supporting surface is connected to one end of the guiding slope close to the driving force receiving portion; the longitudinal plane intersects with the second supporting surface.

[0020] 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 slide groove extending along the axial direction of the barrel body, and the gate slides in cooperation with the slide groove.

[0021] 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.

[0022] A preferred solution is that the gate further includes an elastic sealing member, which is located on a side of the sealing plate facing the carbon powder receiving member and is arranged opposite to the carbon powder receiving member, and the elastic extrusion portion is located on the elastic sealing member.

[0023] It can be seen that the elastic seal is located between the gate and the toner receiving member of the electronic photographic imaging device. Therefore, after the toner receiving member is docked with the powder discharge port, the toner receiving member abuts against the elastic seal. 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. 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. Therefore, 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.

[0024] A preferred solution is that the gate further comprises an elastic sealing member, the elastic sealing member is located on a side of the sealing plate facing away from the carbon powder receiving member, and the elastic extrusion portion is located on the elastic sealing member.

[0025] It can be seen that 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.

[0026] A further solution is that a mounting groove is provided on the side wall of the sealing plate facing away from the toner receiving member, an opening is provided at the bottom of the mounting groove, the opening vertically penetrates the sealing plate, and an elastic sealing member is installed in the mounting groove. The elastic sealing member includes a movable member and a sealing ring, and the sealing ring is arranged on the side of the movable member facing away from the toner receiving member. The movable member includes a main body and a limiting portion, the limiting portion protrudes outward from the side wall of the main body, the limiting portion is adjacent to the bottom wall of the mounting groove, the main body extends downward into the opening, and a docking groove is provided on the lower side of the main body, and the docking groove can be engaged with the toner receiving member.

[0027] It can be seen that the toner receiving part abuts against the elastic sealing part. When the toner receiving part tilts, a force will be applied to the movable part. Only the elastic sealing part and the toner receiving part are adaptively adjusted in position, and the overall position of the gate plate will not be changed, thereby achieving a better sealing effect.

[0028] A further solution is that a powder outlet is provided on the sealing plate, and the powder outlet vertically penetrates the sealing plate and the elastic sealing member, and when the gate is in the open position, the powder outlet is opposite to and connected with the powder outlet.

[0029] A preferred solution is that the toner receiving component includes a main body, two support rods and two matching protrusions, the powder inlet is arranged on the main body and penetrates the main body in a vertical direction, the electronic photographic imaging device also includes a sealing member, the sealing member is used to open and close the powder inlet, 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, the matching protrusions are arranged on the opposite side walls of the two support rods and slide with the guide slope.

[0072] Carbon powder cartridge first embodiment:

[0073] See also Figure 1 and Figure 2 The electronic photographic imaging device comprises a powder cartridge receiving member 10 and a toner cartridge 2. The powder cartridge receiving member 10 is provided with a powder cartridge receiving chamber 11. The toner cartridge 2 is detachably mounted in the powder cartridge receiving chamber 11. The bottom of the powder cartridge receiving chamber 11 is provided with a toner cartridge receiving member 12 and a sealing member 13 ( Figure 8 As shown in the figure, after the toner cartridge 2 is installed in place, the toner receiving member 12 and the toner discharge port 40 of the toner cartridge 2 are arranged opposite to each other in the vertical direction.

[0074] The toner receiving member 12 includes a main body 121, two support rods 122 and two matching protrusions 123. The main body 121 is provided with a powder inlet 124 extending through the main body 121 in a vertical direction. Figure 8 As shown, the seal 13 extends into the powder inlet 124 from the lower end of the powder inlet 124 and is used to open and close the powder inlet 124. The two support rods 122 are relatively arranged on both sides of the main body 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.

[0075] See also Figure 3 The toner cartridge 2 includes a cartridge body 3 and an end cap 4. 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.

[0076] The end cover 4 includes an outer cover 5 and a shell body 6. The outer cover 5 is arranged outside the shell body 6. A powder discharge port 40 is arranged at the bottom of the shell body 6. A gate 7 is detachably installed on the shell body 6. A powder outlet 71 is provided on the gate 7. The shell body 6 is provided with a slide groove 61 extending along the axial direction of the barrel body 3. The gate 7 slides with the slide groove 61 to open or close the powder discharge port 40. Buckles 72 are provided on both sides of the gate 7.

[0077] See also Figures 4 to 8, only one of the two opposite sides of the shell 6 is provided with an unsealing guide rail 62, and the other side is provided with a support member 63, the unsealing guide rail 62 is located on the first side wall 623 of the shell 6 and protrudes outward from the first side wall 623, the support member 63 is located on the second side wall 624 of the shell 6 and protrudes outward from the second side wall 624, and the unsealing guide rail 62 is provided with a guide slope 621, and the guide slope 621 is inclined relative to the central axis of the barrel body 3. Along the axial direction of the barrel body 3, from the end away from the teeth 34 to the end close to the teeth 34, the guide slope 621 is inclined from bottom to top. A longitudinal plane perpendicular to the central axis of the barrel body 3 and passing through the powder discharge port 40 intersects with the guide slope 621, and the end of the guide slope 621 close to the teeth 34 is higher than the intersection position of the longitudinal plane and the guide slope 621. The mating protrusion 123 of the toner receiving member 12 moves along the guide slope 621 to force the toner receiving member 12 to move in the vertical direction relative to the sealing member 13 to open or close the powder inlet 124 .

[0078] The support member 63 includes a support surface 631 and a stop surface 632. The support surface 631 extends along the axial direction of the barrel body 3. The longitudinal plane intersects with the support surface 631. The stop surface 632 extends from the end of the support surface 631 away from the teeth 34 to the lower side of the support surface 631. The stop surface 632 is set at an acute angle with the support surface 631. The stop surface 632 and the support surface 631 are smoothly transitionally connected by the arc surface 633.

[0079] See also Figures 8 to 10 The gate 7 includes a plate body 70 and an elastic seal 73. A seal installation groove 64 is provided at the bottom of the housing 6. The powder discharge port 40 is located in the seal installation groove 64. An elastic seal 74 is provided in the seal installation groove 64. The elastic seal 74 is provided with a communication port 741 communicating with the powder discharge port 40. The elastic seal 73 and the elastic seal 74 are respectively provided on opposite sides of the plate body 70. The elastic seal 74 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 elastic seal 73 is located on the side of the plate body 70 facing the toner receiving member 12 and is arranged vertically opposite to the main body 121 of the toner receiving member 12, 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 gate 7 is provided with a powder outlet 71 which penetrates the plate 70 and the 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 powder outlet 71 on the gate 7 are opposite and connected.

[0080] See also Figures 11 to 18 The installation process of the carbon powder cartridge 2 is as follows. Fig.11 and Fig.12As shown, after the toner cartridge 2 is loaded into the cartridge receiving chamber 11 of the electronic photographic imaging device, the buckle 72 of the gate 7 is locked and fixed, and the left mating protrusion 123 on the toner receiving member 12 is located at the bottom end of the unsealing guide rail 62, and the right mating protrusion 123 is located at a position farther from the support member 63 in the axial direction of the cartridge body 3. Fig.13 and Fig.14 As shown, the toner cartridge 2 is pushed forward, the gate 7 is fixed, and when the housing 6 moves forward, the gate 7 moves relative to the housing 6, and as the toner cartridge 2 moves forward, the mating protrusion 123 on the left moves upward along the unsealing guide rail 62, the toner receiving member 12 gradually moves upward to approach the toner cartridge 2, and the mating protrusion 123 on the right gradually approaches the supporting member 63. Fig.15 and Fig.16 As shown, the toner cartridge 2 is pushed forward continuously, and the powder outlet 40 of the housing 6 gradually approaches the powder outlet 71 of the gate 7 along the insertion direction, and the mating protrusion 123 on the left side continues to move upward along the unsealing guide rail 62, and the toner receiving member 12 further moves upward, and the mating protrusion 123 on the right side moves to a position adjacent to the support member 63. Due to the setting of the stop surface 632, at this time, the mating protrusion 123 on the right side will not enter the lower side of the support surface 631, but will move to the support surface 631 under the action of the arc surface 633 connecting the stop surface 632 and the support surface 631. Finally, as shown in FIG. Fig.17 and Fig.18 As shown, the toner cartridge 2 moves forward to the extreme position, at which time, the powder outlet 71 of the gate 7 and the powder discharge port 40 of the shell 6 are relative to and connected in the vertical direction, and the toner receiving member 12 moves upward to a position abutting against the 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. At this time, the mating protrusion 123 on the right side is supported on the supporting surface 631 to realize the positioning of the toner receiving member 12.

[0081] As can be seen from the above, since the toner cartridge is only provided with an unsealing guide rail on one side, it is possible to avoid the mating protrusions on both sides being not at the same horizontal position or the toner cartridge being tilted during installation, which may cause the toner cartridge to get stuck during installation. In addition, the elastic seal is located between the gate and the toner receiving member of the electronic photographic imaging device, so after the toner receiving member and the powder discharge port are docked, the two are elastically connected, so 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 more compressed, and when the toner receiving member is pulled to a lower position by the guide rail, the elastic seal is less compressed. Since the elastic seal can be elastically deformed under force, the toner receiving member and the powder discharge port can maintain a good sealing state to prevent toner from leaking from the docking position.

The second support wall 352 is located at one end of the unsealing guide rail 362 close to the teeth, and the third support wall 353 is located above the unsealing guide rail 362. A first opening 3501 is provided on the first side wall 350 at a position opposite to the first support wall 351.

[0089] Carbon powder cartridge fourth embodiment:

[0090] As a description of a fourth embodiment of the toner cartridge of the present invention, only the differences from the third embodiment of the toner cartridge described above will be described below.

[0091] In this embodiment, only one of the two opposite sides of the outer cover is provided with an unsealing guide rail, and the other side is not provided with a support member.

[0092] Carbon powder cartridge fifth embodiment:

[0093] As an explanation of the fifth 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.

[0094] See also Figure 25 to Figure 28 The gate 57 includes a sealing plate 575, a support plate 576 and an elastic sealing member 573. The sealing plate 575 is used to open and close the powder discharge port 540. The sealing plate 575 in this embodiment is equivalent to the plate body 70 in the first embodiment. The buckles 572 are arranged on the left and right sides of the sealing plate 575. The support plate 576 is vertically connected to the left edge of the sealing plate 575 and is located outside the shell 56. Three engaging protrusions 5751 are arranged on the left side wall of the sealing plate 575. Three engaging grooves 5762 are opened on the support plate 576. Each engaging protrusion 5751 is inserted into the corresponding engaging groove 5762 and has an interference fit with the engaging groove 5762.

[0095] The elastic seal 574 is located on the side of the sealing plate 575 facing the inside of the housing 56, and is used to achieve sealing between the housing 56 and the gate 57. The elastic seal 573 is located on the side of the sealing plate 575 facing the toner receiving member 12, so that when the toner receiving member 12 moves upward to a position engaged with the powder discharge port 540, it can elastically abut against the gate 57. The gate 57 is provided with a powder discharge port 571, which vertically penetrates the sealing plate 575 and the elastic seal 573. When the gate 57 is in the open position, the powder discharge port 540 on the housing 56 and the powder discharge port 571 on the gate 57 are opposite and connected.

[0096] The unsealing guide rail 5761 is arranged on the support plate 576, and the unsealing guide rail 5761 protrudes outward from the surface of the support plate 576. The unsealing guide rail 5761 is provided with a guide bevel 57611, and the guide bevel 57611 is inclined relative to the central axis of the barrel body 53. Along the axial direction of the barrel body 53, from the end away from the teeth 534 to the end close to the teeth 534, the guide bevel 57611 is inclined from bottom to top, and a longitudinal plane perpendicular to the central axis of the barrel body 53 and passing through the powder discharge port 540 intersects with the guide bevel 57611, and the end of the guide bevel 57611 close to the teeth 534 is higher than the intersection position of the longitudinal plane and the guide bevel 57611. The mating protrusion 123 of the toner receiver 12 moves along the guide slope 57611 to force the toner receiver 12 to move in the vertical direction relative to the seal 13 to open or close the powder inlet 124. At the same time, along with the installation operation of the toner cartridge, the guide slope 57611 guides the toner receiver 12 to move in the vertical direction toward the powder discharge port 540 until the toner receiver 12 docks with the powder discharge port 540.

[0097] See also Figure 29 to Figure 33 The installation process of the carbon powder cartridge 52 is as follows. Fig.29 and Fig.30 As shown in FIG. 1 , when the toner cartridge 52 is installed in the toner cartridge receiving chamber 11 of the electronic photographic imaging device, before the buckle 572 of the gate 57 is locked and fixed, the mating protrusion 123 moves upward along the guide slope 57611 of the unsealing guide rail 5761, thereby driving the toner receiving member 12 to move upward to open the powder inlet 124. At this time, the toner receiving member abuts against the elastic sealing member 573 of the gate 57, and then as shown in FIG. Fig.31 As shown, the buckle 572 of the gate 57 is engaged and fixed with the electronic photographic imaging device. At this time, the gate 57 is still located at the position of closing the powder discharge port 540. Then, as shown in FIG. Fig.32 and Fig.33As shown, continue to push the cartridge body 53 forward to open the powder discharge port 540. At this time, the powder outlet 571 of the gate 57 is vertically opposite and connected to the powder discharge port 540 of the shell 56, and the powder discharge port 540 of the carbon powder cartridge 52 is connected to the powder inlet 124 of the powder cartridge receiving chamber 11.

[0098] As can be seen from the above, during the installation process of the toner cartridge, the powder inlet of the electronic photographic imaging device is opened first before the powder outlet is opened. In this way, the powder outlet is prevented from opening before the powder inlet during the installation process, which may cause leakage of toner in the toner cartridge. In addition, since the toner cartridge is only provided with an unsealing guide rail on one side, it is possible to avoid the mating protrusions on both sides being not at the same horizontal position or the toner cartridge being tilted during the installation process, which may cause the toner cartridge to get stuck during the installation process. In addition, the elastic seal is located between the gate and the toner receiving member of the electronic photographic imaging device. Therefore, after the toner receiving member and the powder outlet are docked, the two are elastically connected. 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 more compressed. When the toner receiving member is pulled to a lower position by the guide rail, the elastic seal is less compressed. Since the elastic seal can be elastically deformed under force, the toner receiving member and the powder outlet can maintain a good sealing state, preventing toner from leaking from the docking position.

[0099] Carbon powder cartridge sixth embodiment:

[0100] As an explanation of the sixth embodiment of the toner cartridge of the present invention, only the differences from the fifth embodiment of the toner cartridge described above will be explained below.

[0101] See also Fig.34 and Fig.35 In this embodiment, there are two support plates 276, which are respectively arranged on opposite sides of the sealing plate 275, and the two support plates 276 are arranged in parallel. Both support plates 276 are provided with an unsealing guide rail 2761 having a guide slope 27611, and the two guide slopes 27611 are arranged in the same plane.

[0102] Carbon powder cartridge seventh embodiment:

[0103] As an explanation of the seventh embodiment of the toner cartridge of the present invention, only the differences from the fifth embodiment of the toner cartridge described above will be explained below.

[0104] See also Fig.36 and Fig.37In this embodiment, there are two support plates, namely support plate 376 and support plate 377. The two support plates 376 are respectively arranged on opposite sides of the sealing plate 375, and the two support plates 376 are arranged in parallel. The unsealing guide rail 3761 is arranged on the support plate 376, and the support plate 377 is provided with a support guide rail 3771. The support guide rail 3771 is provided with a first support surface 3772 and a stop surface 3773. The first support surface 3772 extends along the axial direction of the cylinder body, and the longitudinal plane intersects with the first support surface 3772. The stop surface 3773 extends from the end of the first support surface 3772 away from the driving force receiving portion to the lower side of the first support surface 3772. The stop surface 3773 and the first support surface 3772 are arranged at an acute angle, and the stop surface 3773 and the first support surface 3772 are smoothly transitionally connected through the arc surface 3774.

[0105] Push the toner cartridge forward, the mating protrusion 123 on the left side moves upward along the unsealing guide rail 3761, the toner receiving piece 12 moves upward to open the powder inlet, and the mating protrusion 123 on the right side moves to a position adjacent to the support guide rail 3771. Due to the setting of the stop surface 3773, the mating protrusion 123 on the right side will not enter the lower side of the first support surface 3772, but will move to the first support surface 3772 under the action of the arc surface 3774 connecting the stop surface 3773 and the first support surface 3772.

[0106] Carbon powder cartridge eighth embodiment:

[0107] As an explanation of the eighth embodiment of the toner cartridge of the present invention, only the differences from the fifth embodiment of the toner cartridge described above will be explained below.

[0108] See also Fig.38 In this embodiment, the unsealing guide rail 4761 also includes a second support surface 47612, which extends along the axial direction of the cylinder body. The second support surface 47612 is connected to one end of the guide slope 47611 close to the driving force receiving portion, and the longitudinal plane intersects with the second support surface 47612.

[0109] Toner cartridge ninth embodiment:

[0112] In this embodiment, the elastic sealing member may not be provided on the side of the sealing plate 975 facing the toner receiving member.

[0113] Toner cartridge tenth embodiment:

[0114] As a description of the tenth embodiment of the toner cartridge of the present invention, only the differences from the first embodiment of the toner cartridge described above will be described below.

[0115] See also Fig.40 and Fig.41 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.

[0116] 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 plate 17 . The size of the powder outlet hole 17314 is larger than that of the center hole 17321 .

[0117] In addition, the structure of the elastic sealing member 173 and the plate body 170 in this embodiment can also be applied to the first to ninth embodiments of the carbon powder cartridge.

[0118] Other embodiments of carbon powder cartridge:

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] The barrel body can be an integrated structure, and the driving force receiving part is arranged on the outer surface of the barrel body; the barrel body can 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.

[0125] In the electronic photographic imaging device, the sealing member can also be arranged above the main body, and the sealing member includes a cover member covering the upper end of the powder inlet, and when the mating protrusion moves upward along the guide slope, the main body of the toner receiving member moves upward, and the cover member flips over to open the powder inlet. The above changes can also achieve the purpose of the present invention.

[0126] 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.
