[0029] Reference Figures 1 to 4 This utility model provides a powder supply cylinder, including a cylinder body 10, a drive frame 20, a top rod 30, a reset component 40, and a docking frame 50;

[0030] The front end of the cylinder 10 has a first powder outlet 11 and the rear end has a powder inlet 12;

[0031] The drive frame 20 is installed at the front end of the cylinder 10 and is provided with a drive gear 60. The drive frame 20 is provided with a second powder outlet 21 that communicates with the first powder outlet 11. The drive frame 20 is provided with a powder stirring frame 70 that extends into the cylinder 10.

[0032] The top rod 30 is movably mounted on the powder mixing frame 70 and is used to close or open the second powder outlet 21;

[0033] The reset component 40 is disposed between the top rod 30 and the drive frame 20;

[0034] The docking frame 50 is mounted on the drive frame 20 and is used to dock to the copier.

[0035] Reference Figures 2-3 In some embodiments, the powder mixing frame 70 is U-shaped to define a sliding groove 71 with openings on both sides. The front end of the push rod 30 is provided with a plug 31 and the rear end is provided with a limiting protrusion 32. The limiting protrusion 32 abuts against the powder mixing frame 70 so that the push rod 30 is limited on the powder mixing frame 70. During assembly, the reset member 40 is first installed on the push rod 30, then the push rod 30 is installed in the sliding groove 71 of the powder mixing frame 70, and then the powder mixing frame 70 is connected to the rear end of the drive frame 20. Subsequently, the drive frame 20 is installed at the front end of the cylinder 10 to complete the connection between the cylinder 10, the drive frame 20, the push rod 30, the powder mixing frame 70 and the reset member 40. Then the whole assembly is fitted into the docking frame 50, and can then be connected to the copier through the docking frame 50. Finally, toner is filled into the cylinder 10 through the toner filling port 12 at the rear end of the cylinder 10.

[0036] In use, the docking frame 50 is docked with the docking structure inside the copier, allowing the toner cartridge to be placed inside the copier. Simultaneously, the drive gear 60 is docked with the drive mechanism inside the copier, thereby driving the cartridge 10, drive frame 20, push rod 30, toner stirrer 70, and reset member 40 to rotate synchronously. It should be noted that when the toner cartridge is placed inside the copier, the push mechanism on the copier will push the push rod 30 toward the inside of the cartridge 10, causing the push rod 30 to open the toner outlet 11 at the front end of the cartridge 10. In some embodiments, the side wall of the cartridge 10 is provided with a concave push groove 90, which is used to drive the toner inside the cartridge 10 to move forward. When the cartridge 10 rotates, it pushes the toner inside it forward until it is discharged through the toner outlet 11 for use by the copier.

The drive frame 20 is provided with a slot 22, and the drive gear 60 is provided with a hook 61. The hook 61 can be hooked into the slot 22 so that the drive gear 60 is mounted on the drive frame 20. Furthermore, the drive gear 60 is provided with a limiting groove 62, and the drive frame 20 is provided with a limiting block 23. The limiting block 23 can extend into the limiting groove 62 when the drive gear 60 is mounted on the drive frame 20 so as to limit the relative rotation between the drive gear 60 and the drive frame 20.

[0039] In some possible embodiments, the drive gear 60 and the drive frame 20 are an integral structure, that is, the drive gear 60 and the drive frame 20 are integrally formed.

[0040] Reference Figures 2-3 In some embodiments, the reset member 40 is configured as a spring, which is sleeved on the push rod 30 with one end abutting against the push rod 30 and the other end abutting against the drive frame 20; the reset member 40 can provide the reset force of the push rod 30, and can push the push rod 30 outward when the toner cartridge is taken out of the copier until the toner outlet 11 on the cartridge 10 is closed.

[0041] Reference Figures 1-2 In some embodiments, the rear end of the cylinder 10 is provided with a powder feeding device 80 that can close or open the powder feeding port 12.

[0042] This utility model also provides a photocopier, including the aforementioned toner supply cylinder.

[0043] The advantages of this utility model are: the above structure can integrate the top rod into the powder mixing frame and house both inside the cylinder, which greatly simplifies the external structure of the powder supply cylinder and reduces the space occupied by the external structure of the powder supply cylinder, thus having very good practicality.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
