[0014] 1. With a convenient toner filling mechanism, the user removes the cover from the surface of the toner cartridge body and then pulls the sealing cover upwards, causing it to slide inside the slot. The slot guides the sealing cover, which in turn moves the sealing gasket and rubber gasket away from the inner wall of the toner filling slot. This allows the sealing cover to be removed from the toner filling slot. The toner filling device then adds toner into the toner hopper through the toner filling slot and the through slot. After filling, the user then installs the sealing cover on the surface of the toner filling slot to seal the surface of the toner filling slot and the through slot, preventing toner leakage.

[0015] 2. By incorporating a uniform developing mechanism, to ensure more uniform developing of the developing roller, the user places the developing roller on the surface of the rotating rod. At this time, the elastic force of the extension spring inside the groove drives the arc-shaped clamp to move, causing the arc-shaped clamp to automatically engage with the corresponding arc-shaped slot. Under the engaging action of the arc-shaped clamp and the arc-shaped slot, the developing roller is installed on the surface of the rotating rod and inside the drum unit, making the developing roller more uniform during developing and realizing the function of uniform developing of the drum. This allows the drum to develop evenly during use and enables quick replacement of the developing roller.

[0016] 3. By incorporating a highly efficient heat dissipation mechanism, the internal temperature of the toner cartridge increases continuously during prolonged operation. At this time, heat dissipation fins are installed on the inner wall of the heat dissipation cavity using mounting screws. These fins dissipate heat from the inside of the toner cartridge, while the heat is conducted through the heat-conducting plate. This allows the heat inside the heat dissipation cavity to be expelled through the heat dissipation holes, resulting in efficient heat dissipation and a more stable internal temperature. This achieves the function of highly efficient heat dissipation, maintaining a relatively stable internal temperature, improving the heat dissipation effect, extending the lifespan of the toner cartridge, and effectively reducing costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] This utility model provides a convenient toner cartridge structure, as shown in the following figure. Figure 1 and Figure 2 As shown, the device includes a toner cartridge body 1. A cover 101 is screwed onto the surface of the toner cartridge body 1, and the cover 101 is detachably connected to the toner cartridge body 1. A drum core 102 is disposed on the surface of the toner cartridge body 1, and the drum core 102 rotates with the inner wall of the toner cartridge body 1. A handle 103 is disposed on the surface of the toner cartridge body 1. A side cover 104 is disposed on the surface of the toner cartridge body 1. A developing roller 107 is disposed inside the toner cartridge body 1, and the developing roller 107 rotates with the inner wall of the toner cartridge body 1. The developing roller 107 and the inner wall of the toner cartridge body 1 are also engaged with each other. A charging roller 106 is disposed on the inner wall of the toner cartridge body 1, and the charging roller 106 is engaged with the inner wall of the toner cartridge body 1. The inner wall of the drum body 1 is provided with a rotating rod 105, which rotates with the inner wall of the drum body 1. One end of the rotating rod 105 extends into the interior of the drum body 1. The interior of the drum body 1 is provided with a toner hopper 108 for storing toner. The interior of the drum body 1 is provided with a gear 109, the surface of which is fixed to the surface of the drum core 102. The gear 109 rotates with the inner wall of the drum body 1. The inner wall of the drum body 1 is provided with a toner filling groove 110. The surface of the toner hopper 108 is provided with a through groove 111, which is connected to the toner filling groove 110. The through groove 111 is connected to the interior of the toner hopper 108.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, the inner wall of the toner cartridge body 1 is provided with a high-efficiency heat dissipation mechanism 2. The high-efficiency heat dissipation mechanism 2 includes heat dissipation fins 21, mounting screws 22 and a high-efficiency heat dissipation assembly 23. The high-efficiency heat dissipation assembly 23 is located on the inner wall of the toner cartridge body 1. The high-efficiency heat dissipation assembly 23 consists of a heat-conducting plate 231, heat dissipation holes 232 and heat dissipation cavity 233. The inner wall of the toner cartridge body 1 has a heat dissipation cavity 233, which is connected to the interior of the toner cartridge body 1. The heat-conducting plate 231 for heat conduction is installed inside the heat dissipation cavity 233. The inner wall of the heat dissipation cavity 233 is provided with heat dissipation fins 21 for heat dissipation. The surface of the heat dissipation fins 21 is threaded with mounting screws 22.

The surface of the toner cartridge body 1 has heat dissipation holes 232 with equal spacing, which are connected to the interior of the heat dissipation cavity 233.

[0027] During implementation, when the toner cartridge body 1 operates for a long time, the internal temperature of the toner cartridge body 1 will continuously rise. At this time, the heat dissipation fins 21 are installed on the inner wall of the heat dissipation cavity 233 by the mounting screws 22. The heat dissipation fins 21 dissipate heat from the inside of the toner cartridge body 1, and the heat conduction plate 231 conducts heat, so that the heat inside the heat dissipation cavity 233 is discharged from the inside of the toner cartridge body 1 through the heat dissipation holes 232, thereby achieving efficient heat dissipation of the inside of the toner cartridge body 1 and making the internal temperature of the toner cartridge body 1 more stable, so as to achieve the function of efficient heat dissipation of the toner cartridge.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, a uniform developing mechanism 3 is provided on the surfaces of the rotating rod 105 and the developing roller 107. The uniform developing mechanism 3 includes an arc-shaped clamp 31, an arc-shaped groove 32, a recess 33, and a tension spring 34. The inner wall of the rotating rod 105 is provided with a recess 33. An arc-shaped clamp 31 is provided inside the recess 33. The arc-shaped clamp 31 and the inner wall of the recess 33 slide against each other. The surface of the developing roller 107 is provided with an arc-shaped groove 32. The arc-shaped groove 32 and the surface of the arc-shaped clamp 31 engage with each other. A tension spring 34 is installed on the surface of the arc-shaped clamp 31. One end of the tension spring 34 is fixed to the inner wall of the recess 33.

[0029] In practice, to make the developing roller 107 develop more evenly, the user places the developing roller 107 on the surface of the rotating rod 105. At this time, under the elastic force of the extension spring 34 inside the groove 33, the arc-shaped clamp 31 moves, so that the arc-shaped clamp 31 automatically clamps into the corresponding arc-shaped slot 32. Under the clamping action of the arc-shaped clamp 31 and the arc-shaped slot 32, the developing roller 107 is installed on the surface of the rotating rod 105 and installed inside the drum body 1, so that the developing roller 107 develops more evenly, thereby realizing the function of uniform development of the drum.

[0030] Furthermore, such as Figure 3 and Figure 6 As shown, the surface of the toner filling tank 110 is provided with a convenient toner filling mechanism 4. The convenient toner filling mechanism 4 includes a sealing cover 41, a tank body 42, and a convenient toner filling assembly 43. The convenient toner filling assembly 43 is provided on the surface of the toner filling tank 110 and is composed of a rubber gasket 431 and a sealing gasket 432. The surface of the toner filling tank 110 is provided with a sealing cover 41, one end of which extends into the interior of the toner filling tank 110. The inner wall of the drum body 1 is provided with a tank body 42. The surface of the tank body 42 and the surface of the sealing cover 41 slide against each other. The surface of the sealing cover 41 is fitted with a sealing gasket 432. The surface of the sealing gasket 432 is covered with a rubber gasket 431 for sealing between the toner filling tank 110 and the sealing cover 41. The surface of the rubber gasket 431 is in contact with the inner wall of the toner filling tank 110.

[0031] In practice, the user removes the cover 101 from the surface of the drum body 1, and then pulls the sealing cover 41 on the surface of the drum body 1 upwards, causing the sealing cover 41 to slide inside the groove 42. Under the action of the groove 42, the sealing cover 41 is guided. At this time, the sealing cover 41 drives the sealing gasket 432 and the rubber gasket 431 to move, causing the sealing gasket 432 to drive the rubber gasket 431 away from the inner wall of the toner filling groove 110, thereby removing the sealing cover 41 from the inside of the toner filling groove 110. The toner filling device adds toner into the toner hopper box 108 through the toner filling groove 110 and the through groove 111. After the toner filling is completed, the user then installs the sealing cover 41 on the surface of the toner filling groove 110 to seal the surface of the toner filling groove 110 and the through groove 111 to prevent toner leakage, thus realizing the function of convenient toner filling of the drum.

[0032] Working principle: In use, first place the toner cartridge body 1 in the designated position. The user removes the cover 101 from the surface of the toner cartridge body 1, then pulls upwards on the sealing cover 41 on the surface of the toner cartridge body 1, causing the sealing cover 41 to slide inside the groove 42. The groove 42 guides the sealing cover 41, causing the sealing cover 41 to move along with the sealing gasket 432 and the rubber gasket 431. This causes the sealing gasket 432 to move away from the inner wall of the toner filling tank 110, thus closing the sealing cover 401. 1. Remove the toner cartridge from the inside of the toner filling slot 110. The toner filling device adds toner into the toner container 108 through the toner filling slot 110 and the through slot 111. After the toner filling is completed, the user installs the sealing cap 41 on the surface of the toner filling slot 110 to seal the surface of the toner filling slot 110 and the through slot 111 to prevent toner leakage. This enables the toner cartridge to be easily filled, making it easier for the user to add toner into the toner container 108 when using the toner cartridge, making the toner cartridge easier to operate.

[0033] Subsequently, the drive device drives the gear 109 to rotate. When the gear 109 rotates, it drives the drum core 102 to rotate on the inner wall of the drum body 1, thereby driving the developing roller 107 and the charging roller 106 to rotate relative to each other inside the drum body 1. The rotation of the charging roller 106 applies a charge to the drum core 102. The toner falls onto the developing roller 107 as the sponge roller rotates. Since the toner is a fine resin particle with a charge, the charge of the toner is opposite in polarity to the charge on the surface of the drum core 102. When the drum core 102 comes into contact with the toner on the developing roller 107, the charged parts of the drum core 102 attract the toner particles, turning the latent image into a real image. Thus, when the paper passes through, the image is formed on the surface of the paper, completing the printing process.

[0034] Subsequently, in order to make the developing roller 107 more uniform during development, the user places the developing roller 107 on the surface of the rotating rod 105. At this time, under the elastic force of the extension spring 34 inside the groove 33, the arc-shaped clamp 31 is driven to move, so that the arc-shaped clamp 31 automatically clamps into the corresponding arc-shaped slot 32. Under the clamping action of the arc-shaped clamp 31 and the arc-shaped slot 32, the developing roller 107 is installed on the surface of the rotating rod 105 and installed inside the drum body 1, so that the developing roller 107 is more uniform during development, thereby realizing the function of uniform development of the drum. This allows the drum to develop evenly during use, and at the same time, it enables quick replacement of the developing roller 107.

[0035] Subsequently, when the toner cartridge body 1 operates for an extended period, the internal temperature of the toner cartridge body 1 will continuously rise. At this time, the heat dissipation fins 21 are installed on the inner wall of the heat dissipation cavity 233 by the mounting screws 22. Under the action of the heat dissipation fins 21, heat is dissipated from the inside of the toner cartridge body 1. Under the action of the heat conduction plate 231, heat is conducted, allowing the heat inside the heat dissipation cavity 233 to be discharged from the inside of the toner cartridge body 1 through the heat dissipation holes 232. This achieves efficient heat dissipation from the inside of the toner cartridge body 1, making the internal temperature of the toner cartridge body 1 more stable, thus realizing the function of efficient heat dissipation of the toner cartridge. This allows the inside of the toner cartridge to be maintained at a relatively stable temperature, improving the heat dissipation effect of the toner cartridge body 1, extending the service life of the toner cartridge body 1, effectively reducing costs, and ultimately completing the use of the toner cartridge.

[0036] 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.
