Therefore, other possible implementation methods that can be known by those skilled in the art based on the embodiments described in this application all belong to the protection scope of this application.

[0047] Powder cartridge embodiment 1

[0048] like Figures 1 to 4 As shown, the powder cartridge 10 has a longitudinally extending shell 11, a protective shell 12 on the left side to protect the driving mechanism installed therein, a handle 112 is located above the shell 11, and an arc-shaped portion is provided below the shell 11. The shell 11 has a developer accommodating portion 111 for accommodating the developer, and the developer accommodating portion 111 may have a stirring member or a conveying member for stirring or vibrating the developer to be transported to the powder outlet 141.

[0049] When the powder cartridge 10 is installed on the developing device and rotates relative to it, it rotates around the central axis of the cylindrical member 141. The abutting portion 153 of the sealing cover 15 abuts against the developing device to prevent the sealing cover 15 from rotating, thereby opening the powder outlet 141. The elastic material layer 17 abuts against the switch member of the powder inlet of the developing device to drive the switch member to move to a position where the powder inlet is opened. The powder outlet 141 corresponds to the powder inlet, and the developer contained in the powder cartridge 10 can enter the powder inlet from the powder outlet 141 and then enter the developing device.

[0050] The rightmost end of the cylindrical member 14 is provided with a coaxial columnar extension 143, on which a storage medium 16 for storing information is provided, and the storage medium 16 includes an electrical connection surface 161 for connecting with the electrical contacts of the electrophotographic imaging device, and a storage part 162 for storing information, wherein the storage part 162 is provided in a cylindrical shape and sleeved on the columnar extension 143, and the electrical connection surface 161 is provided as two annular surfaces, fixed outside the storage part 162. The electrical connection surface shown in the figure is a whole annular shape, and it can be understood that in other embodiments, the electrical connection surface can be an arc shape, as long as it can ensure that the electrical connection can still be maintained after the cylindrical member rotates a certain angle. In the case where the powder cartridge does not need to rotate, the electrical connection surface is provided in an annular shape and on the columnar extension, so that the electrical contacts of the electrophotographic imaging device can contact the electrical connection surface from various angles, and the electrical connection between the storage medium and the electrophotographic imaging device can also be made more convenient.

[0051] Powder cartridge embodiment 2

[0052] The structure of the powder cartridge in this embodiment may be similar to or the same as that in Embodiment 1, except that the sealing cover for opening and closing the powder outlet is different.

[0053] like Figures 5 to 8 As shown, the powder cartridge 20 has a longitudinally extending shell 21, a protective shell 22 on the left side to protect the driving mechanism installed therein, a handle 212 is located above the shell 21, and an arc portion is provided below the shell 21. The shell 21 has a developer accommodating portion for accommodating the developer, and the developer accommodating portion may have a stirring member or a conveying member for stirring or vibrating the developer to be transported to the powder outlet 241. A connector 23 is provided on the upper right side of the powder cartridge 20, and a cylindrical member 24 is provided below. The cylindrical member 24 has a powder outlet 241 arranged on the cylinder wall, and a guide rail 242 is arranged on the right side. The sealing cover 25 can be rotatably arranged at the powder outlet 241 relative to the cylindrical member 24. The sealing cover 25 includes a cover part 251 for closing and opening the powder outlet 241 and a guide part 252 having a guide groove and cooperating with the guide rail 242 to guide the sealing cover 25 to rotate relative to the cylindrical member 24. The guide part 252 is also provided with a serration part 253, which can increase the friction when the sealing cover 25 is manually opened, so as to facilitate the opening of the sealing cover 25. Elastic material layers 27 are arranged on both sides of the powder outlet 241. Before the powder cartridge 20 is installed on the developing device, the sealing cover 25 is first rotated to open the powder outlet 241, and then the powder cartridge 20 is installed on the developing device. When the powder cartridge 20 rotates, the elastic material layer 27 abuts against the switch component of the powder inlet of the developing device and drives the switch component to move to the position of opening the powder inlet. The powder outlet 241 corresponds to the powder inlet, and the developer contained in the powder cartridge 20 can enter the powder inlet from the powder outlet 241 and then enter the developing device.

[0054] The rightmost end of the cylindrical member 24 is provided with a coaxial columnar extension, on which a storage medium 26 for storing information is provided, and the storage medium 26 includes an electrical connection surface for connecting with the electrical contacts of the electrophotographic imaging device, and a storage part for storing information.

[0055] Powder cartridge embodiment 3

[0056] Except for the different opening method of the powder outlet, the structure of the powder cartridge in this embodiment may be similar to or the same as the structures in Embodiment 1 and Embodiment 2.

[0057] like Figures 9 to 13 As shown, the powder cartridge 30 has a longitudinally extending shell 31, a protective shell 32 on the left side to protect the driving mechanism installed therein, a handle 312 is located above the shell 31, and an arc-shaped portion is provided below the shell 31. The shell 31 has a developer accommodating portion for accommodating the developer, and the developer accommodating portion may have a stirring member or a conveying member for stirring or vibrating the developer to be transported to the powder outlet 341. A connector 33 is provided above the right side of the powder cartridge 30, and a cylindrical member 34 is provided below. The cylindrical member 34 has a powder outlet 341 provided on the cylinder wall, and a sealing member 35 is provided inside the cylindrical member 34 to open and close the powder outlet 341. Elastic material layers 37 are provided on both sides of the powder outlet 341. When the powder cartridge 30 is installed in the developing device and rotated, it rotates around the central axis of the cylindrical member 34. The elastic material layer 37 abuts against the switch member of the powder inlet of the developing device and drives the switch member to move to a position to open the powder inlet. At this time, although the powder outlet 341 is turned to a downward position corresponding to the powder inlet, the cover portion 351 of the sealing member 35 closes the powder outlet 341, and the developer cannot be discharged to the developing device.

[0058] The opening action of the powder outlet 341 is carried out through the mutual cooperation of the conveying screw 38, the sealing member 35 and the cylindrical member 34 which serve as the developer conveying member. The right end of the conveying screw 38 is provided with an external thread 381 which meshes with the internal thread 353 of the sealing member 35. When the conveying screw 38 rotates driven by the gear 321, due to the meshing of the internal and external threads, the sealing member 35 abuts against the protrusion 342 inside the cylindrical member 34 and cannot rotate. It is pushed to the right by the conveying screw 38 until the opening 352 corresponds to the powder outlet 341, and the powder outlet 341 is opened. The sealing member 35 continues to move to the right until its internal thread 353 is disengaged from the external thread 381 of the conveying screw 38, and the powder outlet 341 is fully opened.

[0059] The rightmost end of the cylindrical member 34 is provided with a coaxial columnar extension 343, on which a storage medium 36 for storing information is provided, and the storage medium 36 includes an electrical connection surface 362 for connecting with the electrical contacts of the electrophotographic imaging device, and a storage portion 361 for storing information. The storage portion 361 is provided in a cylindrical shape and sleeved on the columnar extension 343, and the electrical connection surface 362 is provided as two annular surfaces and fixed on the storage portion 361.

[0060] Powder cartridge embodiment 4

[0061] Except for the different arrangement and opening method of the powder outlet, the structure of the powder cartridge in this embodiment may be similar to or the same as the structures in Embodiment 1, Embodiment 2 and Embodiment 3.

[0062] like Figures 14 to 16 As shown, the powder cartridge 40 has a longitudinally extending shell 41, a protective shell 42 on the left side to protect the driving mechanism installed therein, a handle 412 is located above the shell 41, and an arc-shaped portion is provided below the shell 41. The shell 41 has a developer accommodating portion for accommodating the developer, and the developer accommodating portion may have a stirring member or a conveying member for stirring or vibrating the developer to be transported to the powder outlet 441. A connector 43 is provided above the right side of the powder cartridge 40, and an outer cylinder 45 and an inner cylinder 44 are coaxially provided below. The inner cylinder 44 has a powder outlet 441 provided on its cylinder wall, and an opening 451 is provided on the cylinder wall of the outer cylinder 45. When the opening 451 corresponds to the powder outlet 441, the powder outlet 441 is opened. Elastic material layers 47 are provided on both sides of the opening 451. When the powder cylinder 40 is installed downwardly on the developing device, the powder outlet 441 is facing downward. Then, when the powder cylinder 40 is rotated with the center axis of the inner and outer cylinders as the axis, the protrusion 442 of the inner cylinder 44 abuts against the developing device and cannot rotate. The outer cylinder 45 rotates until its opening 451 corresponds to the powder outlet 441. At the same time, the elastic material layer 47 drives the switch part of the powder inlet of the developing device to move to the position of opening the powder inlet, and the developer can enter the powder inlet from the powder outlet 441.

[0063] The rightmost end of the inner cylinder 44 is provided with a coaxially arranged columnar extension 443, on which an electrical connection surface 462 for storing the medium 46 is arranged, and a storage portion 461 of the storage medium 46 is arranged on the protrusion 431 of the connecting member 43, and an elastic material layer can be arranged between the storage portion 461 and the protrusion 431, and the storage portion 461 maintains electrical contact with the electrical connection surface 462, and when the powder cartridge 40 rotates, the storage portion 461 slides relative to the electrical connection surface 462 in the case of electrical connection. The split arrangement of the storage medium can make the installation of the storage medium more flexible and the electrical connection with the electronic photographic imaging device more convenient.

[0064] Powder cartridge embodiment 5

[0065] Except for the different arrangement of the chip, the structure of the powder cartridge in this embodiment may be similar to or the same as that in Embodiment 3.

[0066] like Fig.17 As shown, the powder cartridge 50 has a longitudinally extending shell 51, a protective shell 52 on the left side to protect the driving mechanism installed therein, a handle 512 is located above the shell 51, and an arc-shaped portion is provided below the shell 51. The shell 51 has a developer accommodating portion for accommodating the developer, and the developer accommodating portion may have a stirring member or a conveying member for stirring or vibrating the developer to be transported to the powder outlet 541. A cylindrical member 54 is provided below. The cylindrical member 54 has a powder outlet 541 provided on the cylinder wall, and a sealing member is provided inside the cylindrical member 54 to open and close the powder outlet 541. Elastic material layers 57 are provided on both sides of the powder outlet 541. When the powder cartridge 50 is installed in the developing device and rotated, it rotates around the central axis of the cylindrical member 54. The elastic material layer 57 abuts against the switch member of the powder inlet of the developing device and drives the switch member to move to a position where the powder inlet is opened. At this time, although the powder outlet 541 is turned to a downward position corresponding to the powder inlet, the sealing member closes the powder outlet 541, and the developer cannot be discharged into the developing device.

[0067] The opening action of the powder outlet 541 is performed by the cooperation of the conveying screw, the sealing member and the cylindrical member 54 which serve as the developer conveying member. For the specific opening process, please refer to the description of the powder outlet opening process in the powder cartridge embodiment 3.

[0068] The rightmost end of the cylindrical member 54 is provided with a coaxial columnar extension, on which an electrical connection surface 562 for storing the medium is provided, and a storage portion 561 of the storage medium is provided on the protrusion 531 of the connecting member 53, an elastic material layer may be provided between the storage portion 561 and the protrusion 531, and the storage portion 561 maintains electrical contact with the electrical connection surface 562, and when the powder cartridge 50 rotates, the storage portion 561 and the electrical connection surface 562 rotate simultaneously. The split storage medium arrangement can make the storage medium installation more flexible and the electrical connection with the electronic photographic imaging device more convenient.

[0069] To summarize, the electrical connection surface of the powder cartridge storage medium is disposed on the columnar extension, and the storage portion of the storage medium can be disposed on the columnar extension at the same time as the electrical connection surface, or can be disposed separately; when the storage portion and the electrical connection surface are disposed separately, the storage portion can slide relative to the electrical connection surface, or the storage portion and the electrical connection surface can be fixedly connected, and the storage medium is flexibly disposed, which facilitates electrical connection with the electronic photographic imaging device.

[0070] Development box embodiment 1

[0071] like Figures 18 to 23As shown, the developing box 100 includes a powder cartridge 10 and a developing device 60, wherein the powder cartridge 10 is detachably mounted on the developing device 60, and the structure of the powder cartridge 10 can refer to the description of the powder cartridge embodiment 1. The specific structure of the developing device 60 is described in detail below.

[0072] The developing device 60 includes a developing frame 61 extending in the longitudinal direction, on which an arc-shaped recess 611 for partially accommodating the powder cartridge 10 is provided, a transmission mechanism 62 is provided on the left side of the developing frame 61, which is used to receive the driving force from the electronic photographic imaging device and transmit it to the driving mechanism of the powder cartridge 10, and a connecting member 63 is provided on the right side to engage with the columnar extension 143 of the powder cartridge. A powder inlet 612 and a accommodating groove 613 are provided on the developing frame 61, and a switch member 64 that can move between an open position and a closed position is provided above the powder inlet. When the opening 641 of the switch member corresponds to the powder inlet 613, the powder inlet 613 is opened. Rack structures 642 are provided on both sides of the opening 641 of the switch member 64, and a avoidance groove 643 is also provided on the right side. A sealing member 65 is also provided on the rear side and the right side of the switch member 64.

[0073] When the powder cartridge is mounted downwardly on the developing device, the elastic material layer 17 abuts against the rack structure 641, the abutting portion 153 of the sealing cover 15 is inserted into the receiving groove 613, the columnar extension 143 and the storage medium 16 arranged thereon enter from the mounting opening 631 of the connecting member to the arc-shaped bottom surface 632 to support the storage medium 16, and then the powder cartridge 10 is rotated with the central axis of the cylindrical member 14 as the axis, the elastic material layer 17 drives the rack structure 641 to further drive the switch member 64 to move, and the abutting portion 153 of the sealing cover 15 is inserted into the receiving groove 613, and the columnar extension 143 and the storage medium 16 arranged thereon enter from the mounting opening 631 of the connecting member to the arc-shaped bottom surface 632 to support the storage medium 16. The connection portion 153 is in contact with the receiving groove 613, and the sealing cover 15 cannot rotate.
