[0002] Image forming devices have a color printing function, where a color image is formed by overlapping images of various colors on a transfer belt. In the prior art, an image forming device includes a main body, an imaging component, and a toner cartridge. The toner cartridge is used to hold toners of different colors and replenish the toners for the imaging component. To prevent the error of installing toner cartridges containing toners of different colors into the main body of the image forming device, color markings are typically added to the toner cartridges. However, this method still poses a risk of users mistakenly installing toner cartridges containing toners of different colors into the main body of the image forming device, causing the toners of different colors to flow into the imaging component and contamination of the toners of different colors. Summary of the Invention

[0003] In order to solve the problem that the toner in the toner cartridge is incorrectly installed on the main body of the image forming device, resulting in the toner in the toner cartridge and the toner in the imaging component being different in color, thereby causing toner contamination.

[0004] In the first aspect, the utility model provides a toner cartridge, which is installed on the body of an image forming device in multiple quantities, and the multiple toner cartridges installed on the body of the image forming device store toners of different colors, and each of the toner cartridges includes a shell, and the shell includes: a first protrusion, which is arranged at one end of the shell away from the installation direction of the toner cartridge installed on the body of the image forming device; wherein the first protrusions of each of the toner cartridges storing toners of different colors installed on the body of the image forming device do not overlap or only partially overlap at the position of the shell of each toner cartridge.

[0005] In combination with the first aspect, in a possible design, the toner cartridge further includes a second protrusion, which is arranged at one end of the shell along the installation direction of the toner cartridge on the main body of the image forming device, and the second protrusions of each toner cartridge storing different color toners installed on the main body of the image forming device do not overlap or only partially overlap at the position of the shell of each toner cartridge.

[0006] In combination with the first aspect, in a possible design, the toner cartridge further includes a third protrusion, wherein the third protrusion is arranged between the first protrusion and the second protrusion, and the third protrusions of each toner cartridge storing different color toners installed on the main body of the image forming device do not overlap or only partially overlap at the position of the shell of each toner cartridge.

[0007] In combination with the first aspect, in a possible design, the first protrusion includes at least one protrusion.

[0008] In combination with the first aspect, in a possible design, the second protrusion includes at least two protrusions.

[0009] In combination with the first aspect, in a possible design, the third protrusion includes at least two protrusions.

[0010] In combination with the first aspect, in a possible design, the toner cartridge is provided with a powder outlet.

[0011] In a second aspect, the present application further provides an image forming apparatus, including a main body. It is characterized in that the toner cartridge as described in any one of the above is detachably installed in the main body, wherein the main body has a plurality of toner cartridge accommodating cavities. The toner cartridge accommodating cavity has a first fitting portion that cooperates with the first protrusion, and the first fitting portions on each toner cartridge accommodating cavity respectively cooperate with the first protrusions of the toner cartridges storing different color toners.

[0012] In combination with the second aspect, in a possible design, the first fitting portion is a groove provided on the toner cartridge accommodating cavity. When the toner cartridge is installed in the main body of the image forming apparatus, the first protrusion of the toner cartridge is inserted into the groove.

[0013] The toner cartridge and the image forming apparatus provided by the present application have at least the following advantages:

[0046] In summary, the positions of the first protrusions 2, 10, 13, 16, the second protrusions 3, 12, 15, 18, and the third protrusions 4, 11, 14, 17 provided on the housings of the toner cartridges 6 storing the first color toner, the toner cartridges 7 storing the second color toner, the toner cartridges 8 storing the third color toner, and the toner cartridges 9 storing the fourth color toner are all different. The first protrusions 2, 10, 13, 16 of the respective toner cartridges 6, 7, 8, 9 storing different color toners and mounted on the main body 20 of the image forming apparatus do not overlap or only partially overlap at the positions on the housings of the respective toner cartridges 6, 7, 8, 9. The second protrusions 3, 12, 15, 18 of the respective toner cartridges 6, 7, 8, 9 storing different color toners and mounted on the main body 20 of the image forming apparatus do not overlap or only partially overlap at the positions on the housings of the respective toner cartridges 6, 7, 8, 9. The third protrusions 4, 11, 14, 17 of the respective toner cartridges 6, 7, 8, 9 storing different color toners and mounted on the main body 20 of the image forming apparatus do not overlap or only partially overlap at the positions on the housings of the respective toner cartridges 6, 7, 8, 9.

[0047] Figures 3 to 7Describes the process of installing the toner cartridge into the main body of the image forming apparatus in this embodiment.

[0048] The image forming apparatus includes a main body 20. The main body 20 has a plurality of toner cartridge receiving cavities 25. Each toner cartridge receiving cavity 25 has a first fitting portion that cooperates with the first protrusions 2, 10, 13, 16, and the first fitting portions on each toner cartridge receiving cavity 25 cooperate with the first protrusions 2, 10, 13, 16 of the toner cartridges 6, 7, 8, 9 that store different color toners respectively. The first fitting portion is an opening groove 22 provided on the toner cartridge receiving cavity 25. When the toner cartridges 6, 7, 8, 9 are installed into the main body 20 of the image forming apparatus, the first protrusions 2, 10, 13, 16 of the toner cartridges 6, 7, 8, 9 are inserted into the opening groove. The main body 20 is further provided with a conductive member 21 and a powder inlet 23.

[0049] When the toner cartridge 1 is inserted into the toner cartridge receiving cavity 25 of the main body 20 of the image forming apparatus, the second protrusion 3 first contacts the conductive member 21 of the image forming apparatus. In order to prevent the toner cartridge 1 from being tilted when inserted into the main body 20 of the image forming apparatus, resulting in interference between the toner cartridge 1 and the conductive member 21 and unable to be inserted into the image forming apparatus, the second protrusion 3 is provided as at least two protrusions. The second protrusion 3 supports the conductive member, and the toner cartridge 1 continues to be inserted into the main body 20 of the image forming apparatus, and the first protrusion 2 enters the opening groove 22 of the image forming apparatus. When the first protrusion 2 enters the opening groove 22, the powder outlet 19 of the toner cartridge 1 is not opened, thereby preventing the mixing of different color toners caused by incorrect installation of the toner cartridges that store different color toners. When the toner cartridge 1 continues to be inserted into the main body of the image forming apparatus, the conductive member 21 on the main body of the image forming apparatus contacts the conductive contact on the toner cartridge, and the powder outlet 19 of the toner cartridge 1 is aligned and communicated with the powder inlet 23 of the image forming apparatus, and the toner cartridge starts to supply toner to the imaging component of the image forming apparatus. The image forming apparatus has a plurality of detachable imaging components, and the imaging components are provided with handles. The handle of each imaging component is formed in a different color by injection molding, and the color of the handle is the same as the color of the toner stored in the imaging component, so as to be able to distinguish the stored toner.

[0050] Further specifically describe the process of installing toner cartridges storing different color toners into an image forming apparatus. Since the positions of the first protrusion, the second protrusion, and the third protrusion of the toner cartridge 6 storing the first color toner, the toner cartridge 7 storing the second color toner, the toner cartridge 8 storing the third color toner, and the toner cartridge 9 storing the fourth color toner on the housing do not overlap or partially overlap with the positions of the first protrusion, the second protrusion, and the third protrusion of the other three toner cartridges storing different color toners on the housing, each toner cartridge storing a different color toner can only be installed in the corresponding toner cartridge accommodating cavity inside the main body of the image forming apparatus, so that the image forming apparatus can print normally. When the toner cartridge 6 storing the first color toner or the toner cartridge 8 storing the third color toner or the toner cartridge 9 storing the fourth color toner or the toner cartridge 7 storing the second color toner is not installed in the corresponding toner cartridge accommodating cavity in the main body 20 of the image forming apparatus, the image forming apparatus will prompt the user that the toner cartridge 6 storing the first color toner or the toner cartridge 8 storing the third color toner or the toner cartridge 9 storing the fourth color toner or the toner cartridge 7 storing the second color toner is not correctly installed. When the toner cartridge 6 storing the first color toner is wrongly installed in the toner cartridge accommodating cavity of the toner cartridge 8 storing the third color toner or the toner cartridge 9 storing the fourth color toner or the toner cartridge 7 storing the second color toner in the main body 20 of the graphic forming apparatus, the second protrusion 3 of the toner cartridge 6 storing the first color toner first contacts the conductive member 21 of the image forming apparatus, and the two protrusions 3-1 and 3-2 of the second protrusion 3 support the conductive member 21 of the image forming apparatus, preventing the toner cartridge 6 storing the first color toner from interfering with the conductive member 21 and unable to continue installing the toner cartridge 6 storing the first color toner due to the lack of the second protrusion or only one of the two protrusions of the second protrusion. Next, the toner cartridge 6 storing the first color toner continues to be inserted into the main body 20 of the image forming apparatus. Since the first protrusion 2 of the toner cartridge 6 storing the first color toner cannot enter the opening slot 22 of the toner cartridge accommodating cavity 25 corresponding to the toner cartridge 8 storing the third color toner or the toner cartridge 9 storing the fourth color toner or the toner cartridge 7 storing the second color toner in the main body 20 of the image forming apparatus, it prevents the toner cartridge 6 storing the first color toner from being wrongly installed in the toner cartridge accommodating cavity corresponding to the toner cartridge 8 storing the third color toner or the toner cartridge 9 storing the fourth color toner or the toner cartridge 7 storing the second color toner in the main body 20 of the image forming apparatus, avoiding damage to the toner cartridge storing the second color toner or damage to the main body of the image forming apparatus caused by further installation of the toner cartridge.If the first protrusion 2 of the toner cartridge 6 storing the first color toner is damaged, the toner cartridge 6 storing the first color toner continues to be installed until the third protrusion 4 contacts the conductive member 21 of the image forming apparatus. The conductive contact provided on the toner cartridge 6 storing the first color toner cannot be correctly connected to the conductive member of the image forming apparatus, resulting in the image forming apparatus being unable to detect the toner cartridge 6 storing the first color toner, and the image forming apparatus being unable to perform printing.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
