[0077] See also Figure 7 The powder cartridge 100 further includes an elastic portion 400, and a mounting portion 1212 is further provided on the powder outlet structure 120. One end of the elastic portion 400 is installed in the mounting portion 1212, and the other end is connected to the movable portion 300, so that the elastic portion 400 is arranged between the movable portion 300 and the powder outlet structure 120. The powder outlet structure 120 is connected to the movable portion 300 via the elastic portion 400, so that when the sliding portion 200 moves relative to the powder outlet structure 120, the powder outlet structure 120 can drive the movable portion 300 to move relative to the sliding portion 200, and because the elastic portion 400 is provided, the movable portion 300 is squeezed on the sliding portion 200 and can move in the +Z axis direction. When not squeezed, the squeezing portion 320 of the movable portion 300 remains extended out of the powder outlet structure 120 in the -Z direction. Specifically, in this embodiment, the elastic part 400 is a spring, the mounting part 1212 is a spring sleeve arranged on the base 122, and a mounting column 330 is provided on the top of the limiting part 310. When the spring is installed between the sliding part 200 and the powder outlet structure 120, one end of the spring is embedded in the spring sleeve, and the other end is sleeved on the mounting column 330, so that the spring is located between the powder outlet structure 120 and the moving part 300, so that the moving part 300 moves in the sliding hole 221. When moving, the lower end of the extrusion part 320 remains extended out of the powder outlet structure 120, which is used to open the protective part 512.

[0078] Furthermore, the lower end of the extrusion portion 320 is respectively provided with a first inclined surface 321 and a second inclined surface 322 on both sides in the X-axis direction, so that when the movable portion 300 moves, it can smoothly move over the protective member 512 through the first inclined surface 321 or the second inclined surface 322 and the elastic portion 400 (the elastic portion 400 stores force), and the first inclined surface 321 and the second inclined surface 322 set on the extrusion portion 320 enable the lower end of the extrusion portion 320 to be inserted into the middle of the protective member 512 under the elastic action of the elastic portion 400 (the elastic portion 400 is released), thereby stretching the protective member 512, that is, the extrusion portion 320 can be squeezed between the first protective member 5121 and the second protective member 5122, so that the first protective member 5121 and the second protective member 5122 are separated in the X-axis direction to expose the powder inlet 511.

[0079] See also Fig.12 , a limiting portion 523 is also provided on the developer replenishing device 500. When the powder discharge structure 120 on the powder cartridge 100 moves to the limiting portion 523, it will be limited by the limiting portion 523 and will no longer move on the developer replenishing device 500. Specifically, in this embodiment, the limiting portion 523 is a limiting protrusion provided on the top of the main body 520, and the limiting protrusion is located on the +X axis side of the guide rail 521 on the top of the main body 520 in the X axis direction, so that the powder discharge structure 120 will be limited by the limiting portion 523 after moving to a certain distance along the guide rail 521 on the top of the main body 520 in the +X axis direction.

[0080] In addition, in this embodiment, a sealing component 600 can also be arranged between the first powder outlet 1211 and the sliding part 200, and a connecting port connected to the first powder outlet 1211 is arranged through the sealing component 600, and the connecting port and the first powder outlet 1211 are arranged opposite to each other in the vertical direction to achieve sealing between the powder outlet structure 120 and the sliding part 200.

[0081] When the powder cartridge 100 provided by the present invention is installed in the developer replenishing device 500, it has the following two states, and the working process of the powder cartridge 100 is as follows:

[0082] See also Fig.12 , Fig.13 , align the slide rail 1222 on the base 122 of the powder discharge structure 120 of the powder cartridge 100 with the guide rail 521 on the developer replenishing device 500, and install the powder cartridge 100 into the developer replenishing device 500 along the +X axis direction.

[0083] See also Fig.14 , Fig.15In the first state, when the powder cartridge 100 is pushed forward in the +X axis direction on the guide rail 521 of the developer replenishing device 500, the shell 110, the sliding part 200 and the moving part 300 of the powder cartridge 100 all move together in the +X axis direction relative to the developer replenishing device 500, and when the lower end of the squeezing part 320 of the moving part 300 extends out of the powder discharge structure 120 and interferes with the top of the main body 520, the moving part 300 contracts in the +Z axis direction; the shell 110, the sliding part 200 and the moving part 300 of the powder cartridge 100 continue to move in the +X axis direction relative to the developer replenishing device 500. The developer replenishing device 500 moves until the first engaging portion 210 on the sliding portion 200 interacts with the second engaging portion 522 of the developer replenishing device 500. With the elastic force of the connecting rod 211, the first engaging portion 210 finally reaches the engaging portion with the second engaging portion 522, thereby temporarily fixing the sliding portion 200 and the developer replenishing device 500 to each other; and when the lower end of the squeezing portion 320 of the moving portion 300 moves to the recessed space of the receiving portion 510 provided on the main body 520, the moving portion 300 is no longer interfered by the main body 520, and the moving portion 200 extends in the -Z axis direction.

[0084] See also Fig.16 , Fig.17 As shown, in the second state, the powder discharge structure 120 of the powder cartridge 100 continues to move relative to the developer replenishing device 500 along the +X axis direction. Since the sliding portion 200 is fixed relative to the developer replenishing device 500, the sliding portion 200 moves relative to the powder discharge structure 120 of the powder cartridge 100 in the -X axis direction, and the powder discharge structure 120 pushes the moving portion 300 to move relative to the sliding portion 200 in the +X axis direction, that is, the extruding portion 320 of the moving portion 300 can move in the sliding hole 221 of the sliding portion 200. When the moving portion 300 moves to the protective member 512 of the developer replenishing device 500, the first inclined surface 321 of the extruding member in the +X axis direction abuts against the side surface of the first protective member 5121 of the protective member 512 in the -X axis direction. The movement of the moving portion 300 relative to the developer replenishing device 500 is manifested as a positive movement relative to the developer replenishing device 500. The movable part 300 moves in the +Z-axis direction, and the elastic part 400 accumulates force, so that the movable part 300 can continue to move on the sliding part 200; and as the movable part 300 continues to move in the +X-axis direction, the movable part 300 moves to the gap 5123 formed between the first protective part 5121 and the second protective part 5122 of the protective part 512, and the elastic part 400 is released. Due to the elastic force of the elastic part 400, the extrusion part 320 of the movable part 300 can be inserted into the gap 5123 formed between the first protective part 5121 and the second protective part 5122 through the first inclined surface 321 and the second inclined surface 322, and through the elastic action of the elastic part 400, the extrusion part 320 is extruded in the -Z-axis direction, and the first protective part 5121 and the second protective part 5122 are stretched open in the X-axis direction, and the protective part 512 above the powder inlet 511 is opened (see Fig.17), at the same time, the powder inlet 511 moves down in the +Z axis direction and abuts against the second powder outlet 220; at this time, the first powder outlet 1211 on the powder outlet structure 120 corresponds to the position of the second powder outlet 220 on the sliding part 200, and the first powder outlet 1211 and the second powder outlet 220 both correspond to the position of the powder inlet 511, so that the first powder outlet 1211, the second powder outlet 220 and the powder inlet 511 are connected, and the developer in the powder cartridge 100 can move to the developer replenishing device 500 through the first powder outlet 1211, the second powder outlet 220 and the receiving hole, and the powder outlet structure 120 is limited by the limiting part 523 on the developer replenishing device 500, and the powder outlet structure 120 and the movable part 300 no longer move in the +X axis direction, and the movable part 300 keeps the protective part 512 open.

[0085] Next, how to take out the toner cartridge 100 from the developer replenishing device 500 of the image forming apparatus will be described:

[0086] Similarly, the powder cartridge 100 is taken out using the principle described above. When the user pulls the powder cartridge 100 by hand, the powder discharge structure 120 of the powder cartridge 100 moves on the guide rail 521 along the -X axis direction relative to the developer replenishing device 500 and the sliding part 200, and the first powder discharge port 1211 of the powder discharge structure 120 moves away from the second powder discharge port 220 and the powder inlet 511 of the sliding part 200 along the -X axis direction. At the same time, the movable part 300 moves relative to the sliding part 200 along the -X axis direction, and the first inclined surface 321 abuts against the side surface of the first protective member 5121 and is squeezed by the first protective member 5121 to move in the +Z direction. The elastic part 400 accumulates force, and as the movable part 200 continues to move along the -X axis direction, it breaks away from the first protective member 5121, the elastic part 400 is released, and the movable part 200 extends out to the -Z direction to reset. During this process, the protective member 512 Close again; the powder discharge structure 120 of the powder cartridge 100 continues to move along the -X axis direction relative to the developer replenishing device 500 and the sliding portion 200 until the movable portion 300 moves in the sliding hole 221 to the side wall 221a of the sliding hole 221 in the -X axis direction. When the movable portion 300 continues to move, the movable portion 300 no longer moves relative to the sliding portion 200, but the movable portion 300 drives the sliding portion 200 to move on the developer replenishing device 500 along the -X axis direction, and the first engaging portion 210 of the sliding portion 200 disengages from the second engaging portion 522, and the sliding portion 200 is no longer fixed to the developer replenishing device 500, but becomes a whole moving together with the powder discharge structure 120 again, and the powder cartridge 100 continues to move along the -X axis direction relative to the developer replenishing device 500, and finally disengages from the developer replenishing device 500, thereby realizing the disassembly of the powder cartridge 100.

[0087] The powder cartridge of the first embodiment is provided with a movable part and an elastic part which are connected to each other. The elastic part is arranged in the mounting part, and the movable part is clamped in the sliding part and can move on the sliding part. One end of the movable part protrudes from the bottom of the powder discharge structure, and the other end is connected to the elastic part. The movable part can move up and down relative to the powder discharge structure under the action of the elastic part, which can avoid interference between the powder cartridge and the electronic imaging device during installation and ensure that the powder cartridge is correctly installed. At the same time, by providing a movable movable part on the powder cartridge, when installing the powder discharge structure, the movable part can be used to open the protective part under the action of the elastic part, so that the powder cartridge can be connected to the developer replenishing device, and the installation, use and disassembly of the powder cartridge can be facilitated.

[0088] Embodiment 2

[0089] This embodiment is substantially the same as the embodiment, and the main difference is that the configuration of the moving part 300 is different. Figure 18-26 In this embodiment, the moving part 300 is configured to be fixed with the sliding part 200 in the X direction and can be moved relative to the sliding part 200 in the Z direction. A powder feeding channel 232 is provided in the moving part 300, and the powder feeding channel 232 is arranged in the second powder outlet 220; in the second state, the shell 110 continues to move relative to the developer replenishing device 500 along the +X direction, so that the guide part 2122 of the shell 110 interacts with the moving part 300, thereby guiding the moving part 300 to move along the -Z direction until the moving part 300 opens the protective part 512 and abuts against the powder inlet 511 of the developer replenishing device 500, and the powder feeding channel 232 in the moving part 300 is connected with the powder inlet 511.

[0090] See also Fig. 20, the powder outlet structure 120 of this embodiment is also provided with a guide portion 2122, and the guide portion 2122 is symmetrically arranged at a position near both sides of the lower part of the powder outlet structure 120. The guide portion 2122 is an inclined structure, and can be specifically an inclined slot. In some embodiments, a first horizontal portion 2123 extending along the +X direction can be connected to the top of the guide portion 2122 on the shell 110, and the length of the first horizontal portion 2123 in the X direction can be made very short, as long as the movable portion 300 can temporarily stay on the first horizontal portion 2123. In other embodiments, other structures other than the first horizontal portion 2123 can also be used so that the movable portion 300 can temporarily not move relative to the shell 110. A second horizontal portion 2124 extending along the -X direction is connected to the bottom of the guide portion 2122 on the shell 110. There are two first horizontal parts 2123, two guide parts 2122 and two second horizontal parts 2124, which are symmetrically arranged with the X-axis as the symmetry axis. The first horizontal part 2123, the guide part 2122 and the second horizontal part 2124 are connected in sequence, so that the movable part 300 can move on the first horizontal part 2123, the guide part 2122 and the second horizontal part 2124 in sequence, and can also move in the opposite direction on the second horizontal part 2124, the guide part 2122 and the first horizontal part 2123 in sequence.

[0091] See also Figure 18-19 The sliding part 200 is generally in the shape of a long plate, which is arranged in the powder outlet structure 120 and can move in the X direction relative to the housing 110. The sliding part 200 is provided with a mounting hole 221a for mounting the moving part 300, so that the moving part 300 can move in the mounting hole 221a relative to the sliding part 200 in the Z direction, but cannot move relative to the sliding part 200 in the X direction. The sliding part 200 is also provided with a second powder outlet 220, which is located in the center of the mounting hole 221a and is used to mount the powder delivery channel 232 of the moving part 300, that is, the axis of the second powder outlet 220 coincides with the axis of the powder delivery channel 232.

[0092] See also Fig.19 The moving part 300 includes a middle plate 231, a powder delivery channel 232 arranged on the middle plate 231 along the Z direction, and side plates 233 arranged in the +Y direction and the -Y direction of the middle plate 231, and a protrusion 234 is provided on the side plate 233. The protrusion 234 is used to interact with the guide portion 2122 of the housing 110. When the moving part 300 moves in the -X direction relative to the housing 110, the protrusion 234 can move from the first horizontal portion 2123 of the housing 110 to the guide portion 2122, and move in the -Z direction along the inclined structure of the guide portion 2122, so that the moving part 300 moves in the -Z direction relative to the housing 110.

[0093] See also Fig.19 and Fig.26The moving part 300 further includes an ejector 24, which is disposed at the lower end of the side plate 233 and is used to interact with the protective member 512 of the image forming device. In this embodiment, the ejector 24 and the side plate 233 are integrally disposed. The ejector 24 has an ejector slope 241, and the ejector slopes 241 on the two side plates 233 face in opposite directions and are symmetrically arranged. Fig.26 There are two protective members 512, which are arranged in the +X direction and the -X direction respectively. The protective members 512 are provided with notches 5123 in the +Y direction and the -Y direction respectively. When the moving part 300 moves along the -Z direction, the ejection slope 241 respectively pushes open the notches 5123 of the protective members 512 at their corresponding positions, thereby separating the two protective members 512 in the +X direction and the -X direction, so that the powder inlet 511 below the protective members 512 is opened. On the contrary, when the moving part 300 moves along the +Z direction, the ejection slope 241 exits the notch 5123 along the +Z direction, so that the two protective members 512 are reset (the protective members 512 can be connected to elastic members to achieve reset), thereby closing the powder inlet 511.

[0094] The powder cartridge 100 of this embodiment has the following three states when in use:

[0095] In the first state, the first powder outlet 1211 on the housing 110 and the second powder outlet 220 on the sliding part 200 are misaligned, the sliding part 200 closes the first powder outlet 1211, so that it cannot discharge powder, the powder cartridge 100 is placed on the guide rail 521 of the developer replenishing device 500 of the image forming device, and the powder cartridge 100 is pushed relative to the developer replenishing device 500 in the +X direction. The housing 110, the sliding part 200 and the moving part 300 of the powder cartridge 100 all push the powder cartridge 100 in the +X direction. The cylinder 100 moves relative to the developer replenishing device 500 until the first engaging portion 210 of the sliding portion 200 interacts with the second engaging portion 522 of the developer replenishing device 500. With the elastic force of the connecting rod 211, the hook 212 passes through the two inclined surfaces of the recess 5221-X direction and finally reaches the recess 5221 and engages with the recess 5221, thereby temporarily fixing the sliding portion 200 and the developer replenishing device 500 to each other, and the moving portion 300 is fixed with the sliding portion 200 (see Fig. 22 At this time, the second powder outlet 220 and the powder delivery channel 232 correspond to the powder inlet 511 in the upper and lower parts.

[0096] In the second state, the housing 110 of the powder cartridge 100 continues to move relative to the developer replenishing device 500 in the +X direction. Since the sliding portion 200 and the moving portion 300 are fixed relative to the developer replenishing device 500, the sliding portion 200 and the moving portion 300 move relative to the housing 110 of the powder cartridge 100. The moving portion 300 first moves relative to the first horizontal portion 2123 of the housing 110 in the -X direction via the protruding column 234 (see FIG. 2 ). Fig. 20The time of this process is determined by the length of the first horizontal portion 2123. The length of the first horizontal portion 2123 can be set very short to reduce the time spent on this process), and moves to the top position of the inclined structure of the guide portion 2122 (see Fig.21 and 23 ), as the housing 110 continues to move in the +X direction relative to the developer replenishing device 500, the movable portion 300 continues to move obliquely downward along the -X and -Z directions relative to the guide portion 2122, and the movement of the movable portion 300 relative to the developer replenishing device 500 is manifested as movement in the -Z direction relative to the developer replenishing device 500. The ejector 24 moves with the movable portion 300 to open the protective member 512 above the powder inlet 511, so that the bottom end of the movable portion 300 abuts against the powder inlet 511, and the powder feeding channel 232 in the movable portion 300 is connected to the powder inlet 511. At this time, the movable portion 300 is located at the bottom end of the inclined structure of the guide portion 2122, and the movable portion 300 no longer moves in the -Z direction (see Fig.24 ).

[0097] In the third state, the housing 110 of the powder cartridge 100 continues to move along the +X direction relative to the developer replenishing device 500 and the moving portion 300, and the moving portion 300 moves along the -X direction relative to the housing 110 on the second horizontal portion 2124 of the housing 110 until the first powder outlet 1211 on the housing 110 moves to a position where it communicates with the powder delivery channel 232 in the moving portion 300 (see Fig.25 ), the top of the moving part 300 is pressed against the sealing component 600 at the first powder outlet 1211, and the developer in the housing 110 enters the powder inlet 511 through the first powder outlet 1211 and the powder feeding channel 232, thereby replenishing the developer. In other embodiments, the third state can be cancelled, and the first powder outlet 1211 on the housing 110 is arranged at a position directly above the moving part 300 when the moving part 300 is finally located at the bottom end of the inclined structure of the guide part 2122 in the second state, so that when the powder feeding channel 232 of the moving part 300 is connected to the powder inlet 511, the first powder outlet 1211 in the housing 110 is simultaneously connected to the powder feeding channel 232, and the developer enters the powder inlet 511 through the first powder outlet 1211 and the powder feeding channel 232, thereby replenishing the developer.

[0098] When the powder cartridge 100 needs to be taken out from the image forming device, the removal process is the reverse operation of the above process: in the third state, the shell 110 of the powder cartridge 100 moves on the guide rail 521 along the -X direction relative to the developer replenishing device 500 and the moving part 300, the first powder outlet 1211 of the shell 110 moves away from the moving part 300 along the -X direction, the first powder outlet 1211 is staggered with the second powder outlet 220 and the powder feeding channel 232, and the first powder outlet 1211 is covered and closed by the sliding part 200. At the same time, the moving part 300 moves relative to the shell 110 on the second horizontal part 2124 of the shell 110 along the +X direction to the bottom end of the inclined structure of the guide part 2122. In the second state, the shell 110 of the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500 and the movable portion 300, and the movable portion 300 moves upwardly along the +X and +Z directions relative to the guide portion 2122 through the protrusion 234. The movement of the movable portion 300 relative to the developer replenishing device 500 is manifested as movement in the +Z direction relative to the developer replenishing device 500. The bottom end of the movable portion 300 leaves the powder inlet 511, and the ejector 24 moves with the movable portion 300. The protective member 512 above the powder inlet 511 is closed again. After the movable portion 300 completes the movement on the guide portion 2122, it enters the first horizontal portion 2123 of the shell 110 and moves to its original position along the +X direction. In the first state, the shell 110 of the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500, and the corresponding parts on the shell 110 abut and apply force to the sliding part 200 or the movable part 300, and cooperate with the elastic force of the connecting rod 211 to make the hook 212 of the sliding part 200 disengage from the recess 5221, and the sliding part 200 and the movable part 300 are no longer fixed to the developer replenishing device 500, but become a whole that moves together with the shell 110 again, and the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500, and finally disengages from the developer replenishing device 500, thereby realizing the disassembly of the powder cartridge 100.

[0099] Embodiment 3

[0100] See also Figure 27-32 The third embodiment is generally similar to the second embodiment, and the main difference is that the structures of the guide part 2122 and the moving part 300 are different.

[0101] The guide part 2122 of this embodiment is a rack, and the moving part 300 of this embodiment is generally a rotating body structure. The moving part 300 is provided with a gear part 235 and a threaded part 236. In this embodiment, the gear part 235 is located at the upper part of the moving part 300, and the threaded part 236 is an external threaded part located in the middle part of the moving part 300. A powder delivery channel 232 is provided in the moving part 300. The sliding part 200 is provided with a mounting hole 221a (also the second powder outlet 220) for mounting the moving part 300, and a threaded part is provided on the inner wall of the mounting hole 221a. In the second state, when the guide part 2122 moves relative to the image forming device along the X direction, the moving part 300 is driven to rotate by the rack of the guide part 2122 through the gear part 235, and the rotational motion is converted into movement in the Z direction under the interaction between the threaded part 236 of the moving part 300 and the threaded part of the sliding part 200.

[0102] The ejector 24 in this embodiment is separately arranged from the main body of the moving part 300. The ejector 24 includes a connecting part 242, and ejector parts 243 and a mounting structure 244 respectively fixed on both sides of the connecting part 242 (i.e., the +Y direction and the -Y direction). When the moving part 300 moves along the -Z direction, the bottom end of the moving part 300 abuts against the connecting part 242, pushing the entire ejector 24 to move in the -Z direction. The reset of the ejector 24 to the +Z direction can be achieved by using an elastic member (not shown in the figure). The mounting structure 244 is specifically a cylinder. The ejector 24 is connected to the sliding part 200 through the mounting structure 244 and can move relative to the sliding part 200 in the Z direction. The range of the Z-direction displacement of the ejector 243 can be limited by the arrangement of relevant components to prevent the ejector 243 from falling off the sliding part 200. The ejector 243 is located at the lower part of the mounting structure 244. The ejector 243 is used to interact with the notch 5123 on the protective member 512. The ejector bevel 241 or a similar arc surface similar to that in the second embodiment can be used. The two protective members 512 are separated in the +X direction and the -X direction by the movement of the ejector 243 in the -Z direction, so that the powder inlet 511 below the protective member 512 is opened. On the contrary, when the moving part 300 moves in the +Z direction, the ejector 243 exits the notch 5123 in the +Z direction, so that the two protective members 512 are reset (the protective members 512 can be connected to an elastic member to achieve reset), thereby closing the powder inlet 511.

[0103] The powder cartridge 100 of this embodiment has the following three states when in use:

[0104] In the first state, the first powder outlet 1211 on the housing 110 and the second powder outlet 220 on the sliding part 200 are misaligned, the sliding part 200 closes the first powder outlet 1211, so that it cannot discharge powder, the powder cartridge 100 is placed on the guide rail 521 of the developer replenishing device 500 of the image forming device, and the powder cartridge 100 is pushed relative to the developer replenishing device 500 in the +X direction. The housing 110, the sliding part 200 and the moving part 300 of the powder cartridge 100 all push the powder cartridge 100 in the +X direction. The cylinder 100 moves relative to the developer replenishing device 500 until the first engaging portion 210 of the sliding portion 200 interacts with the second engaging portion 522 of the developer replenishing device 500. With the elastic force of the connecting rod 211, the hook 212 passes through the two inclined surfaces of the recess 5221-X direction and finally reaches the recess 5221 and engages with the recess 5221, thereby temporarily fixing the sliding portion 200 and the developer replenishing device 500 to each other, and the moving portion 300 is fixed with the sliding portion 200 (see Fig. 27 and 30 At this time, the second powder outlet 220 and the powder delivery channel 232 correspond to the powder inlet 511 in the upper and lower parts.

[0105] In the second state, the housing 110 of the powder cartridge 100 continues to move relative to the developer replenishing device 500 along the +X direction. Since the sliding portion 200 and the moving portion 300 are fixed relative to the developer replenishing device 500, the sliding portion 200 and the moving portion 300 move relative to the housing 110 of the powder cartridge 100. The rack of the guide portion 2122 meshes with the gear portion 235 of the moving portion 300, driving the moving portion 300 to rotate. Under the interaction of the groove holes, the moving part 300 moves along the -Z direction and contacts the ejector 24, so that the ejector 24 also moves along the -Z direction, and the protective member 512 above the powder inlet 511 is opened, so that the bottom end of the moving part 300 abuts against the powder inlet 511, and the powder delivery channel 232 in the moving part 300 is connected with the powder inlet 511. At this time, the rack of the guide part 2122 is disengaged from the gear part 235 of the moving part 300, and the moving part 300 no longer moves in the -Z direction (see Fig.31 ).

[0106] In the third state, the housing 110 of the powder cartridge 100 continues to move along the +X direction relative to the developer replenishing device 500 and the moving part 300 until the first powder outlet 1211 on the housing 110 is connected to the powder delivery channel 232 in the moving part 300 (see Fig.32), the top of the moving part 300 is pressed against the sealing component 600 at the first powder outlet 1211, and the developer in the housing 110 enters the powder inlet 511 through the first powder outlet 1211 and the powder delivery channel 232, thereby replenishing the developer. In other embodiments, the third state can be cancelled, and the first powder outlet 1211 on the housing 110 is set at a position directly above the moving part 300 when the gear part 235 of the moving part 300 is disengaged from the rack of the guide part 2122 in the second state, so that when the powder delivery channel 232 of the moving part 300 is connected to the powder inlet 511, the first powder outlet 1211 in the housing 110 is simultaneously connected to the powder delivery channel 232, and the developer enters the powder inlet 511 through the first powder outlet 1211 and the powder delivery channel 232, thereby replenishing the developer.

[0107] When the powder cartridge 100 needs to be taken out from the image forming device, the taking-out process is the reverse operation of the above process: in the third state, the shell 110 of the powder cartridge 100 moves on the guide rail 521 along the -X direction relative to the developer replenishing device 500 and the moving part 300, the first powder outlet 1211 of the shell 110 moves away from the moving part 300 along the -X direction, the first powder outlet 1211 is staggered with the second powder outlet 220 and the powder feeding channel 232, and the first powder outlet 1211 is covered and closed by the sliding part 200. At the same time, the gear part 235 of the moving part 300 moves relative to the shell 110 to the rack of the guide part 2122. In the second state, the shell 110 of the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500 and the movable portion 300, and the movable portion 300 is driven by the rack of the guide portion 2122 through the gear portion 235 to move along the +Z direction, and the bottom end of the movable portion 300 leaves the powder inlet 511, and the ejector 24 is reset by the corresponding elastic member, so that the protective member 512 above the powder inlet 511 is reclosed, and the movable portion 300 returns to its original position under the drive of the rack of the guide portion 2122. In the first state, the shell 110 of the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500, and the corresponding parts on the shell 110 abut and apply force to the sliding part 200 or the movable part 300, and cooperate with the elastic force of the connecting rod 211 to make the hook 212 of the sliding part 200 disengage from the recess 5221, and the sliding part 200 and the movable part 300 are no longer fixed to the developer replenishing device 500, but become a whole that moves together with the shell 110 again, and the powder cartridge 100 continues to move along the -X direction relative to the developer replenishing device 500, and finally disengages from the developer replenishing device 500, thereby realizing the disassembly of the powder cartridge 100.

[0108] The powder cartridge 100 of the second and third embodiments of the present invention, by providing a movable moving part 300 on the powder cartridge 100, establishes a powder delivery channel 232 between the first powder outlet 1211 of the powder cartridge 100 and the powder inlet 511 of the developer replenishing device 500, thereby simply and effectively realizing the connection and disconnection between the first powder outlet 1211 of the powder cartridge 100 and the powder inlet 511 of the developer replenishing device 500, thereby facilitating the installation, use and disassembly of the powder cartridge 100.

[0109] The above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
