[0031] Reference Figures 3-5The snap-fit ​​assembly 4 includes a hollow tube 41 fixedly installed on the right end face of the feed tube 21. An electromagnet 42 is slidably connected inside the hollow tube 41. A pressure plate 43 is fixedly connected to the end face of the electromagnet 42. A connecting spring 44 is fixedly connected to the end of the electromagnet 42 away from the pressure plate 43. A wire tube 45 is fixedly connected to the side wall of two adjacent hollow tubes 41. The hollow tubes 41 and the wire tubes 45 are circumferentially distributed on the right end face of the feed tube 21. Specifically, multiple hollow tubes 41 are distributed circumferentially on the right end face of the feed tube 21, and the wire tubes 45 are circumferentially fixed to the feed tube 21. The pressure plate 43 is located on the side of the electromagnet 42 away from the center of the feed tube 21. The pressure plate 43 is adapted to fit against the inner wall of the drum body 1. A push switch 46 is fixedly connected to the top left side of the feed tube 21. The hollow tube 41 and the wire tube 45 are connected in pairs. Multiple electromagnets 42 are connected in series and electrically connected to the push switch 46. The magnetic poles of the adjacent ends of the multiple electromagnets 42 are opposite. Pressing the push switch 46 will energize the electromagnets 42. At this time, the multiple electromagnets 42 attract each other and drive the pressure plate 43 to detach from the inside of the drum body 1, so as to facilitate the removal of the feed tube 21.

[0032] Furthermore, the powder-grinding assembly includes a crossbar 51 and a connecting rod 52, with one end of the crossbar 51 fixedly connected to a hollow tube 41 of the snap-fit ​​assembly 4; for details, please refer to... Figures 5-6 The powder grinding assembly includes a crossbar 51 fixedly installed on the left side of the hollow tube 41. A connecting rod 52 is fixedly connected to the surface of the crossbar 51. The crossbar 51 is located inside the feed tube 21. The connecting rod 52 is located inside the feed tube 21 on the side near the feed inlet. A support rod 53 is fixedly connected to the bottom of the connecting rod 52. A rotating rod 54 is rotatably connected to the bottom of the support rod 53. A fan blade 55 is fixedly connected to the left end face of the rotating rod 54. An eccentric block 56 is fixedly connected to the right surface of the rotating rod 54.

[0033] Working principle: The operator first presses the press switch 46, causing multiple electromagnets 42 to attract each other. At this time, the electromagnets 42 will compress the connecting spring 44 and drive the pressure plate 43 to move into the hollow tube 41. Then, the feed tube 21 is inserted into the corresponding position of the drum body 1. After that, the press switch 46 is released. At this time, the electromagnets 42 no longer attract each other. Then, the electromagnets 42 will be repelled by the connecting spring 44 and drive the pressure plate 43 to move out of the hollow tube 41. When the right side of the feed tube 21 moves into the inside of the drum body 1, the pressure plate 43 is repelled by the connecting spring 44 and abuts against the inner wall of the drum body 1. At this time, the locking block 34 will abut against the inner wall of the annular groove 37 under the action of the rebound force of the pressure spring 33. Then, the feed tube 21 is rotated so that the opening of its feed port faces downward. At this time, the locking block 34 is locked into the slot 38 opened at the bottom of the annular groove 37.

[0034] The operator can then insert the opening of the pneumatic toner bottle containing toner into the feed tube 21, with the opening of the pneumatic toner bottle facing upwards. Next, pull the slide bar 32 away from the feed tube 21. The slide bar 32 will pull the locking block 34 out of the locking slot 38. Then, rotate the feed tube 21 so that the opening of its inlet faces upwards. The feed tube 21 will then cause the locked pneumatic toner bottle to rotate until the opening of the pneumatic toner bottle faces downwards. At this point, the pneumatic toner bottle can be pressed to expel airflow and blow the toner into the feed tube 21. The blowing airflow propels the toner through the feed tube 21 into the drum body 1. At the same time, the airflow also drives the fan blades 55 to rotate. The rotating fan blades 55 break up the toner moving inside the feed tube 21, preventing any clumps of toner from entering the drum body 1. After adding toner, the opening of the feed tube 21 is rotated downwards in the reverse manner, so that the opening of the pneumatic toner bottle is upwards. At this time, the pneumatic toner bottle can be removed directly, preventing the toner inside the pneumatic toner bottle from leaking out from the opening of the feed tube 21.

[0035] When it is necessary to disassemble the feed tube 21, the press switch 46 can be pressed to make multiple electromagnets 42 attract each other. At this time, the electromagnets 42 will drive the pressure plate 43 to detach from the inside of the drum body 1. Then the feed tube 21 can be taken out from the inside of the drum body 1 for cleaning.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
