Description

Technical Field

[0001] This utility model relates to the field of printing consumables, and in particular to a toner cartridge structure and a toner cartridge. Background Technology

[0002] A typical toner cartridge includes a photosensitive drum, a conductive roller, and a toner hopper. During use, the toner cartridge is installed inside a photocopying device, with the conductive roller contacting the conductive parts of the device to power the drum core. Existing toner cartridges are cleaned using a sliding cleaner, requiring a groove on the cartridge for the cleaner to slide along. However, this type of cartridge relies on the internal space of the photocopying device to seal the groove, resulting in poor sealing. This allows paper scraps and dust to adhere to the drum core through the groove, affecting printing quality. Furthermore, it suffers from poor heat dissipation. Therefore, a new toner cartridge structure and design are urgently needed to address these issues. Utility Model Content

[0020] Reference Figures 1 to 5 A toner cartridge structure includes a frame 10, a cleaner 20, and a dust cover 30; The frame 10 is provided with a cavity 11 and a slide groove 12 communicating with the cavity 11, and the drum core is rotatably disposed in the cavity 11; The cleaner 20 is slidably disposed within the cavity 11 and extends at least partially into the groove 12; The dust cover 30 is rotatably mounted on the frame 10 and has several heat dissipation holes 31 arranged at intervals along its length. The dust cover 30 is used to open or close the slide 12.

[0021] In this invention, during use, the toner cartridge, drum core, etc. are installed on the frame 10. The cleaner 20 is slid to the beginning of the slide 12, and then the dust cover 30 is rotated to close the slide 12. The dust cover 30 not only closes the slide 12 but also limits the position of the cleaner 20. The heat generated by the drum during operation is discharged through the heat dissipation holes 31 on the dust cover 30. When the drum needs to be cleaned, the drum is removed from the photocopying equipment, the toner cartridge is removed from the frame 10, and the dust cover 30 is rotated to open the slide 12, while simultaneously removing the limit on the cleaner 20. At this time, the cleaner 20 is operated to slide in the slide 12, so that the cleaner 20 cleans the drum core in the cavity 11.

[0022] Reference Figure 2 , Figures 4-5 In some embodiments, the cleaner 20 includes a toggle part 21 located outside the slide groove 12 and a first cleaning part 22 and a second cleaning part 23 disposed opposite to each other in the cavity 11. The first cleaning part 22 and the second cleaning part 23 abut against the cavity wall of the cavity 11. When the drum needs to be cleaned, the toggle part 21 is operated to drive the first cleaning part 22 and the second cleaning part 23 to slide in the cavity 11 to clean the drum core. It should be noted that scrapers can be installed on the first cleaning part 22 and the second cleaning part 23 to fit against the outer wall of the drum core, thereby achieving a better cleaning effect.

[0023] Reference Figures 1-5 In some embodiments, a toner cartridge structure further includes a conductive wire 50 disposed within the cavity 11, with one end connected to the drum core and the other end connected to a conductive part within the photocopying device via a conductive component 40; preferably, the conductive component 40 includes an integrally formed first hook portion 41, a fixing portion 42, an abutment portion 43, and a second hook portion 44, the first hook portion 41 hooking onto the other end of the conductive wire 50, the fixing portion 42 connected to the frame 10, the abutment portion 43 abutting against the conductive part within the photocopying device, and the second hook portion 44 hooking onto the frame 10.

In a further embodiment, the fixing portion 42 is wound in a spiral shape, and the frame 10 is provided with a protrusion 13. The fixing portion 42 is sleeved on the protrusion 13, which can play a role in fixing the conductive component 40. When the drum is installed in the photocopying equipment, the abutment portion 43 abuts against the conductive part in the photocopying equipment. The photocopying equipment supplies power to the drum core through the conductive part, the abutment portion 43, the fixing portion 42, the first hook portion 41, and the conductive wire 50, which can improve the stability of the connection between the drum and the conductive part of the photocopying equipment, thereby improving the photocopying effect.

[0025] Reference Figures 2-5 In some embodiments, the conductive wire 50 is threaded between the first cleaning section 22 and the second cleaning section 23; this arrangement can make full use of the space in the cavity 11, ensuring that the cleaner 20 can slide and clean normally without affecting the connection and power supply between the conductive wire 50 and the drum core.

[0026] Reference Figures 1-5 In some embodiments, a toner cartridge structure further includes a limiting cover 70 connected to the frame 10 via a detachable structure 60, wherein a limiting groove 71 for defining the conductive component 40 is formed between the limiting cover 70 and the frame 10; preferably, the detachable structure 60 is configured as a snap-fit ​​structure.

[0027] Reference Figures 1-5 In some embodiments, the diameter of the heat dissipation hole 31 is smaller than the diameter of the groove 12. This arrangement can both seal the groove 12 and dissipate heat.

[0028] A toner cartridge, comprising the aforementioned toner cartridge structure.

[0029] The advantages of this invention are as follows: the above structure allows the dust cover to be rotated to a closed slide groove for dust prevention during use of the toner cartridge, and heat dissipation through the heat dissipation holes on it, thus combining dust prevention and heat dissipation. Furthermore, when cleaning the toner cartridge, the dust cover can be opened and the cleaning tool can be slid to clean the drum core, meeting the usage requirements.
