[0116] Working principle of the invention:

[0117] When toner needs to be added to the toner chamber, first remove the drum unit 1 from the printer. After removal, the protective frame 61 shields the photosensitive drum 2 from light. The protective frame 61 moves the carrier 62, which in turn moves the assembly 63, causing the assembly 63 to engage with the positioning post 64. As the assembly 63 moves downward, it presses against the first fixing part 444. Under the action of the first spring 45, the first fixing part 444 engages with the assembly 63, thus installing the protective frame 61 and providing light protection for the photosensitive drum 2. Then, pull the traction frame 610, which pulls the auxiliary rod 611 to move, and the auxiliary rod 611 pulls the locking post 69 to move. The locking post 69 disengages from the collection frame 71, and then the collection frame 71 separates from the protective frame 61. Remove the waste discharge plug 8 to expose the waste discharge port, and then insert the fixing tube 74 into the inside of the waste discharge port. Then, invert the drum body 1 to pour out the waste powder, so that the waste powder falls into the inside of the collection frame 71 for collection. After the waste powder is discharged, seal the waste discharge port with the waste discharge plug 8 and adjust its position.

[0118] Pulling the sealing plug 36 causes it to move the docking cylinder 35 and the telescopic tube 33, pulling the docking cylinder 35 out of the toner filling seat 31 and extending the telescopic tube 33. Pulling the docking cylinder 35 unfolds the folding cylinder 34. Then, rotating the sealing plug 36 disengages it from the docking cylinder 35, removing the auxiliary cylinder 51 from the telescopic tube 33 and the docking cylinder 35. Adjusting the position of the drum body 1 so that the docking cylinder 35 is vertically upward, inserting the port of the toner container into the docking cylinder 35, and adding toner into the docking cylinder 35. The toner then flows along the telescopic tube 33 and the inlet ring 32 into the toner chamber. After toner addition is complete, wait for a certain time, then remove the toner container from the docking cylinder 35. Reinstall the sealing plug 36 in its original position, then fold the folding cylinder 34, and push the telescopic tube 33 a certain distance into the toner filling seat 31. Figure 9As shown, at this time, the toner cartridge body 1 is placed horizontally, and then shaken to mix the toner. Then, the moving body 441 is pulled to move, so that the moving body 441 pulls the support body 442 through the connecting part 443. The support body 442 drives the first fixed part 444 to move to the second stroke. The first fixed part 444 is disengaged from the assembly body 63, so that the assembly body 63 and the protective frame 61 can be removed. Then, the toner cartridge body 1 is moved to the installation position on the printer.

[0119] At this time, push the sealing plug 36 to fully retract the telescopic tube 33 into the interior of the toner dispenser 31. During this process, the sealing plug 54 comes into contact with the push frame 58, and the sealing plug 54 compresses the second spring 57, thereby pushing the sealing plug 54 to disengage from the interior of the docking groove 53, opening the interior of the docking groove 53, and connecting the interior of the toner chamber with the interior of the auxiliary cylinder 51. The drying pack 52 absorbs moisture and protects the interior of the toner chamber. After the docking cylinder 35 is magnetically fixed, the drum body 1 is installed into the interior of the printer, and it can continue to be used.
