Then, the user places the end cap body 102 on the surface of the cover 105, causing the cover 105 to move the retaining block 23 to engage with the inner wall of the end cap body 102. Under the action of the retaining block 23, the end cap body 102 and the cover 105 are positioned and installed. Then, the user tightens the mounting screws 21 on the surface of the mounting plate 22. Under the action of the mounting screws 21, the cover 105 and the end cap body 102 are respectively assembled onto the surfaces of the toner cartridge housing 1 and the top cover 101. If the end cap needs to be removed... When the body 102 and the cover 105 are removed from the surface of the toner cartridge housing 1, the user loosens the mounting screws 21 on the surface of the mounting plate 22, and then pulls the end cover body 102 away from the side away from the toner cartridge housing 1, so that the end cover body 102 is away from the surface of the locking block 23, and removes the end cover body 102 from the surface of the cover 105. The user then pulls the cover 105 away from the surface of the toner cartridge housing 1, so that the cover 105 is away from the surface of the toner cartridge housing 1, and the locking slot body 24 and the locking plate 25 are away from the interior of the cover 105, thereby removing the cover 105 from the surface of the toner cartridge housing 1. This realizes the function of the toner cartridge structure to facilitate the disassembly and assembly of the end cover body 102, so that the toner cartridge structure is convenient for the user to disassemble and assemble the end cover body 102 and the cover 105, making the toner cartridge structure more convenient for the user to operate.

[0035] Subsequently, the toner inside the toner cartridge housing 1 is stirred by the stirrer 104. When toner needs to be added to the toner cartridge housing 1, the user pulls the sealing cap 41 away from the toner inlet 108, removing the sealing cap 41 from the surface of the toner inlet 108. The user then adds toner to the toner cartridge housing 1 through the toner inlet 108. Afterward, the user places the sealing cap 41 back on the surface of the toner inlet 108, causing the sealing cap 41 to automatically engage with the fixing post 42 inside the fixing groove 43. The movable rubber pad 44 moves to contact the inner wall of the toner filling port 108. Under the action of the rubber pad 44, the sealing cover 41 and the toner filling port 108 are sealed. Under the joint action of the fixing post 42 and the fixing groove 43, the sealing cover 41 is prevented from falling off, so as to realize the function of sealing the toner cartridge structure to prevent toner leakage. This allows the toner cartridge structure to avoid the phenomenon of toner inside the toner cartridge shell 1 leaking out from the inside of the toner filling port 108 when in use, making the toner cartridge structure more airtight during use, and finally completing the use of the toner cartridge structure.
