Description

Technical Field

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

[0002] Toner cartridges are toner supply devices used in printers / copiers, providing toner for printing / copying. A toner cartridge typically consists of a cartridge body, a toner-stirring roller, and a drive gear. The drive gear connects to the toner-stirring roller and, after docking with the drive mechanism on the printer / copier, drives the roller to agitate the toner inside the cartridge. However, existing toner cartridges have a very complex assembly structure, with numerous docking slots on the cartridge body for docking with printing / copying equipment. This makes the overall assembly of the toner cartridge quite complex, resulting in high production costs and poor versatility.

[0028] Reference Figures 1 to 6 A general-purpose toner cartridge includes a cartridge body 10, a mixing roller 20, a drive gear 30, and a sliding cover 40;

[0029] The box body 10 is provided with a powder cavity 51. The front side of the box body 10 is provided with a drive port 52, the rear side is provided with a first docking position 53, and the lower end is provided with a powder outlet 54. The drive port 52 and the powder outlet 54 are connected to the powder cavity 51. The left and right sides of the box body 10 have a neat plane.

[0030] The mixing roller 20 is rotatably disposed inside the box body 10 with one end facing the drive port 52;

[0031] The drive gear 30 is mounted on the drive port 52 and connected to the mixing roller 20;

[0032] The sliding cover 40 is slidably mounted on the box body 10 and is used to close or open the powder outlet 54.

[0033] In this invention, during use, the toner cartridge is placed entirely into the photocopying equipment, such that the drive gear 30 on the front side of the housing 10 engages with the drive mechanism on the photocopying equipment, and the first engagement position 53 on the rear side of the housing 10 engages with the engagement mechanism on the photocopying equipment, thus fixing the toner cartridge inside the photocopying equipment. When the drive mechanism on the photocopying equipment drives the drive gear 30 to rotate, it will drive the mixing roller 20 to rotate in the powder chamber 51, thereby agitating the toner in the powder chamber 51 and discharging it from the powder outlet 54 for use by the photocopying equipment. Furthermore, the sliding cover 40 is provided with a second engagement position 90, which can engage with the engagement mechanism on the photocopying equipment and slide to the powder outlet position when the toner cartridge is placed inside the photocopying equipment, thereby opening the powder outlet 54.

[0034] Reference Figures 1-4 In some embodiments, the housing 10 includes a front shell 11 and a rear cover 12 with an opening at the rear end of the front shell 11. A rotating head 13 is provided on the rear cover 12, and the other end of the powder stirring roller 20 is connected to the rotating head 13. Furthermore, the front shell 11 and the rear cover 12 are injection molded, and the rear cover 12 is ultrasonically welded to the front shell 11, which can maintain good sealing between the front shell 11 and the rear cover 12 and prevent toner leakage.

[0035] Reference Figures 1-4 In some embodiments, the rear cover 12 is provided with a toner filling port 14, and also includes an end cap 60 threadedly connected to the toner filling port 14. When the toner in the cartridge 10 is consumed, the end cap 60 can be unscrewed to expose the toner filling port 14, and then toner can be refilled into the toner chamber 51 through the toner filling port 14 to achieve the recycling of the toner cartridge.

[0036] Reference Figures 1-4 In some embodiments, the drive gear 30 is connected to the mixing roller 20 via a docking structure 70; as a preferred embodiment of the docking structure 70, the docking structure 70 includes a cross docking groove 71 disposed on the drive gear 30 and a cross connector 72 disposed on the mixing roller 20, the cross connector 72 being inserted into the cross docking groove 71.

[0037] Reference Figures 1-4In some embodiments, the left side of the housing 10 is provided with a first slide groove 81 and a first positioning block 82, the right side of the housing 10 is provided with a second slide groove 83 and a second positioning block 84, the left side of the sliding cover 40 is provided with a first slider 85 and a third positioning block 86, the right side of the sliding cover 40 is provided with a second slider 87 and a fourth positioning block 88, the first slider 85 extends into the first slide groove 81, the second slider 87 extends into the second slide groove 83, the sliding cover 40 can be in the closed position when the third positioning block 86 abuts against the first positioning block 82 to close the powder outlet 54, or the sliding cover 40 can be in the powder outlet position when the fourth positioning block 88 abuts against the second positioning block 84 to open the powder outlet 54; this arrangement enables the sliding cover 40 to switch from the closed position to the powder outlet position under the push of the docking mechanism on the photocopying equipment, and avoids the sliding cover 40 accidentally retracting to the closed position and affecting the use of the photocopying equipment.

[0038] The advantages of this utility model are: the above structure not only simplifies the structure of the toner cartridge, but also makes the toner cartridge more versatile, and makes the structure of the toner cartridge more compact, which can hold more toner and extend the service life of the toner cartridge, thus having very good practicality.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
