One end of the sealing plug 110 extends into the interior of the powder filling port 111.

[0028] Furthermore, such as Figure 3 and Figure 6 As shown, a cost-saving mechanism 2 is provided on the surface of the mixing rack body 106 and the inner wall of the gear shaft 109. The cost-saving mechanism 2 consists of a mounting stud 21, a mounting groove 22, a mounting block 23, and a screw hole 24. The surface of the gear shaft 109 has a mounting groove 22, and one end of the mixing rack body 106 extends into the interior of the mounting groove 22. Mounting blocks 23 are installed on the surface of the mixing rack body 106. The mounting blocks 23 are engaged with the inner wall of the mounting groove 22. The surface of the mixing rack body 106 has a mounting stud 21, and the inner wall of the gear shaft 109 has a screw hole 24. One end of the mounting stud 21 extends into the interior of the screw hole 24 and is threaded into the inner wall of the screw hole 24.

[0029] During implementation, the other end of the mixing frame body 106 moves into the interior of the mounting groove 22. The mixing frame body 106 drives the mounting block 23 to automatically engage with the inner wall of the mounting groove 22. Under the action of the mounting block 23, the mixing frame body 106 and the gear shaft 109 are positioned and assembled. Subsequently, the user rotates the mixing frame body 106, causing the mixing frame body 106 to drive the mounting stud 21 to move into the interior of the screw hole 24. With the threaded engagement between the mounting stud 21 and the screw hole 24, the mixing frame body 106 is installed on the surface of the gear shaft 109 on the surface of the gear body 108, completing the assembly work between the mixing frame body 106 and the gear body 108, so as to achieve the function of saving costs for the toner cartridge.

[0030] Furthermore, such as Figure 4 and Figure 7As shown, a high-efficiency powder feeding mechanism 3 is provided on the surface of the sealing plug 110 and the inner wall of the powder feeding port 111. The high-efficiency powder feeding mechanism 3 is composed of a rubber pad 31, a silicone pad 32, an anti-detachment clip 33, and a fixing groove 34. The surface of the sealing plug 110 is covered with a silicone pad 32, and the surface of the silicone pad 32 is covered with a rubber pad 31 for sealing between the sealing plug 110 and the powder feeding port 111.

The inner wall of the first side cover 101 is provided with a fixing groove 34. The fixing groove 34 and the surface of the anti-detachment clip 33 are engaged with each other.

[0031] During implementation, the user places the sealing plug 110 on the surface of the toner filling port 111 and then pushes the sealing plug 110, causing the sealing plug 110 to automatically engage with the anti-disengagement clip 33 inside the corresponding fixing slot 34. Under the engaging action of the anti-disengagement clip 33 and the fixing slot 34, the sealing plug 110 is prevented from disengaging, thus installing the sealing plug 110 on the surface of the first side cover 101. At this time, the rubber pad 31 on the inner wall of the sealing plug 110 moves to contact the inner wall of the toner filling port 111. Under the combined action of the silicone pad 32 and the rubber pad 31, the sealing plug 110 and the toner filling port 111 are sealed, preventing the toner inside the drum housing 1 from leaking out between the sealing plug 110 and the toner filling port 111, thereby achieving the function of efficient toner filling of the drum.

[0032] Furthermore, such as Figure 5 and Figure 8 As shown, the surfaces of the toner cartridge housing 1 and the cover 102 are provided with a convenient assembly mechanism 4. The convenient assembly mechanism 4 consists of an assembly screw 41, an anti-loosening sleeve 42, a positioning slot 43, and a positioning block 44. The surface of the toner cartridge housing 1 is equipped with an anti-loosening sleeve 42. The surface of the anti-loosening sleeve 42 is threadedly connected to the assembly screw 41. One end of the assembly screw 41 passes through the anti-loosening sleeve 42 and the toner cartridge housing 1 in sequence and is threadedly fastened to the inner wall of the cover 102. The inner wall of the toner cartridge housing 1 is equipped with a positioning block 44. The surface of the cover 102 is provided with a positioning slot 43. The surfaces of the positioning slot 43 and the positioning block 44 engage with each other.

[0033] During implementation, the user places the cover 102 on the surface of the toner cartridge housing 1. The positioning block 44 on the inner wall of the toner cartridge housing 1 automatically engages with the corresponding positioning slot 43. Under the engaging action of the positioning block 44 and the positioning slot 43, the toner cartridge housing 1 and the cover 102 are positioned and assembled. Subsequently, the user tightens the assembly screws 41 on the surface of the toner cartridge housing 1. Under the action of the assembly screws 41, the toner cartridge housing 1 and the cover 102 are installed. Under the action of the anti-loosening screw sleeve 42, the assembly screws 41 are prevented from loosening, thus enabling the toner cartridge housing 1 and the cover 102 to be stably assembled. When the user needs to inspect and maintain the various components inside the toner cartridge housing 1, it is more convenient to operate, so as to realize the function of easy assembly of the toner cartridge.

[0034] Working principle: In use, first place the toner cartridge housing 1 in the designated position. The user places the stirring frame body 106 inside the toner cartridge housing 1, causing one end of the stirring frame body 106 to move and engage with the inner wall of the gear on the inner wall of the toner cartridge housing 1. Then, the other end of the stirring frame body 106 moves into the mounting groove 22, causing the mounting block 23 to automatically engage with the inner wall of the mounting groove 22. Under the action of the mounting block 23, the stirring frame body 106 and the gear shaft 109 are positioned and assembled. Then, the user rotates the stirring frame body 106... 6. This causes the mixing frame body 106 to move the mounting stud 21 into the screw hole 24. With the threaded engagement between the mounting stud 21 and the screw hole 24, the mixing frame body 106 is mounted on the surface of the gear shaft 109 on the surface of the gear body 108, completing the assembly work between the mixing frame body 106 and the gear body 108. This achieves the function of saving costs for the toner cartridge, allowing the mixing frame body 106 and the gear body 108 to be assembled separately when using the toner cartridge. This makes the assembly of the toner cartridge simpler, increases production efficiency, and saves costs for customers.

[0035] Subsequently, the user places the cover 102 on the surface of the toner cartridge housing 1. The positioning block 44 on the inner wall of the toner cartridge housing 1 automatically engages with the corresponding positioning slot 43. Under the engaging action of the positioning block 44 and the positioning slot 43, the toner cartridge housing 1 and the cover 102 are positioned and assembled. Then, the user tightens the assembly screws 41 on the surface of the toner cartridge housing 1. Under the action of the assembly screws 41, the toner cartridge housing 1 and the cover 102 are installed. Under the action of the anti-loosening screw sleeve 42, the assembly screws 41 are prevented from loosening, thus enabling the toner cartridge housing 1 and the cover 102 to be stably assembled. When the user needs to inspect and maintain the various components inside the toner cartridge housing 1, it is more convenient to operate, so as to realize the function of easy assembly of the toner cartridge. This makes it easier for the user to disassemble and assemble the cover 102 when using the toner cartridge, making the toner cartridge more convenient to operate when using it.

[0036] Subsequently, the user pulls the sealing plug 110 away from the side cover 101, removing it from the surface of the first side cover 101. At this point, the sealing plug 110 is away from the inside of the toner filling port 111. During use, toner is added to the inside of the drum housing 1 through the toner filling port 111. After adding toner, the user places the sealing plug 110 on the surface of the toner filling port 111 and pushes it. This causes the sealing plug 110 to automatically engage with the anti-detachment clip 33 inside the corresponding fixing slot 34. The engagement of the anti-detachment clip 33 and the fixing slot 34 prevents the sealing plug 110 from detaching, thus allowing the sealing plug 110 to be removed. The seal plug 110 is installed on the surface of the first side cover 101. At this time, the rubber pad 31 on the inner wall of the sealing plug 110 moves to contact the inner wall of the toner filling port 111. Under the combined action of the silicone pad 32 and the rubber pad 31, the sealing plug 110 and the toner filling port 111 are sealed, preventing the toner inside the drum housing 1 from leaking out between the sealing plug 110 and the toner filling port 111. This achieves the function of efficient toner filling for the drum, thereby preventing the toner inside the drum housing 1 from leaking out during the use of the drum. This also makes it less likely for the sealing plug 110 to come loose accidentally during use, and finally completes the use of the drum.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
