The carbon powder box 3 is provided with a powder adding port 40, the side wall in the carbon powder box 3 is provided with a turning plate 32 for sealing the powder adding port 40, the upper side of the turning plate 32 is hinged to the side wall right above the powder adding port 40 and in the carbon powder box 3, the lower side of the turning plate 32 is a free end, in the embodiment, a turning plate locking device is arranged on the side wall outside the carbon powder box 3 and below the powder adding port 40 and at a position corresponding to the free end of the turning plate 32, the turning plate locking device comprises a long groove 33 distributed along the height direction, the top end of the long groove 33 corresponds to the position of the free end of the turning plate 32, the inner wall of the long groove 33 is provided with a sliding chute 34 distributed along the long groove 33, a sliding buckle 35 is connected in the sliding chute 34, a magnet 36 is fixed on the sliding buckle 35, a second spring 37 is fixed between the lower surface of the magnet 36 and the bottom end of the long groove 33, an iron sheet or iron sheet is fixed on one side of the turning plate 32 facing the magnet 36, the turning plate 32 is made of iron, so that the magnet 36 and the turning plate 32 can be magnetically connected, the second spring 37 is used for enabling the magnet 36 to be in the top end of the long groove 33 in the initial state, so that an iron sheet on the turning plate 32 is attracted, the turning plate 32 is prevented from being opened, when powder is required to be added, the magnet 36 is pressed downwards, the magnetic attraction effect on the turning plate 32 is relieved for the magnet 36, at the moment, the external carbon powder bottle tip is aligned to the powder adding port 40, the turning plate 32 is extruded and turned, the carbon powder bottle tip extends into the carbon powder box 3 to be inclined, carbon powder is poured into the carbon powder box 3, the carbon powder bottle is drawn out after the filling is finished, the turning plate 32 is turned over under the action of gravity, the magnet 36 is loosened, the second spring 37 pushes the magnet 36 upwards, the magnet 36 is magnetically connected with the turning plate 32, the turning plate 32 is enabled to be attached to the inner wall of the carbon powder box 3, and the carbon powder filling is more convenient and rapid.

In this embodiment, the size of the opening end of the toner cartridge 3 matches the size of the inner surface of the left through groove, so that the toner cartridge 3 cannot shake after being installed, and can be more stable, the cleaning scraper 20 is fixed with a pull ring 38 facing one side of the waste toner cartridge 15, and the cleaning scraper 20 can be installed more conveniently through the pull ring 38.

The specific working process of the invention is as follows:

the folding pull rod 28 is pulled to enable the folding pull rod 28 to move relatively, the two lock rods 39 are driven to be separated from the clamping piece 30, at the moment, the two folding pull rods 28 are pulled as handles, the transverse plate 24 drives the first clamping rod 9 and the second clamping rod 16 to move upwards, so that the first clamping rod 9 is separated from the second clamping groove 8, the second clamping rod 16 is separated from the waste powder box 15, the limit of the waste powder box 15 and the carbon powder box 3 is relieved, at the moment, the waste powder box 15 can be pulled out, the waste powder box 15 is cleaned, the carbon powder box 3 can be pulled out, the elastic buckle 6 is extruded when the carbon powder box 3 is pulled out, the elastic buckle 6 retracts to enable the carbon powder box 3 to be smoothly separated from the shell 1,

when the second clamping rod 16 moves upwards to be separated from the waste powder box 15 and the cleaning scraper 20 needs to be disassembled and cleaned, because the second clamping rod 16 does not press and limit the sliding bolt 22, an operator can push the sliding bolt 22 back up and down to the cavity 21 above the first movable groove 18 and pull the cleaning scraper 20 to separate the fourth clamping groove 19 from the first movable groove 18, at this time, the cleaning scraper 20 is disassembled, after the cleaning scraper 20 and the waste powder box 15 are cleaned, firstly, the sliding bolt 22 is pushed back to the cavity 21 above the first movable groove 18, then, the cleaning scraper 20 slides in from the opening at the left side of the first movable groove 18 and is clamped in the fourth clamping groove 19, so that the cleaning scraper 20 is placed in the placing groove 17, then, the sliding bolt 22 is put down, at this time, the sliding bolt 22 tightly presses and fixes the cleaning scraper 20, then, the waste powder box 15 is installed and fixed, the second clamping rod 16 is inserted, the second clamping rod 16 presses and fixes the sliding bolt 22, the cleaning blade 20 cannot shake and move, and the waste powder box 15 is mounted;

when needing to add the carbon dust, through pushing down magnet 36 for magnet 36 removes the magnetic attraction effect to turning over board 32, at this moment aim at the carbon dust bottle point mouth of outside with powder mouth 40, the extrusion turns over board 32, make and turn over the board 32 and turn over, carbon dust bottle mouth stretches into the inside back slope of carbon dust box 3, pour the carbon dust into in the carbon dust box 3, take out the carbon dust bottle after filling, turn over board 32 and overturn under the action of gravity, loosen magnet 36, second spring 37 upwards promotes magnet 36, magnet 36 and turn over board 32 magnetism and be connected, make and turn over board 32 and the laminating of 3 inner walls of carbon dust box, make and load the carbon dust convenient and fast more.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
