Description

Technical Field

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

[0002] The printer drum unit is a crucial component of a laser printer. During operation, the developing roller absorbs toner, which is then adsorbed onto the surface of the OPC roller. Areas on the OPC roller exposed to the laser beam also absorb toner. The toner cartridge is the toner working area within the drum unit. Current drum units are generally separate, with the drum core, toner container, and waste toner box each using different structures for fixation. While this achieves the goal of removability, it also adds significant weight and size to the overall drum unit, resulting in higher costs for a consumable item. Furthermore, in traditional drum units, the toner container is recessed, with all parts except the outer wall completely embedded within the drum. This imposes limitations on the shape and size of the toner container, preventing the development of larger capacity containers. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a toner cartridge that can be integrated through the side cover, thereby saving the cost of toner cartridge materials and removing the volume limitation of the toner hopper.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] An integrated toner cartridge includes a drum core, a toner hopper, and a waste toner box. The drum core, toner hopper, and waste toner box are integrally connected by side covers on both sides. The side covers on both sides form an open space on the front side for the toner hopper to be installed. A roller bracket is integrally provided on the rear side of the toner hopper. A side space for accommodating a gear set is provided between the toner hopper and the side covers.

[0006] Furthermore, in this utility model, the drum core, powder hopper, and waste powder box are fixedly connected to the side cover by screws.

[0007] Furthermore, in this utility model, the front end of the powder hopper extends from the open space formed by the two side covers on the front side.

[0008] Furthermore, the roller support in this utility model includes a roller mounting groove one for mounting an adsorption roller and a roller mounting groove two for mounting a developing roller, both located on the rear side of the powder hopper.

[0009] Furthermore, the side space in this utility model includes a cavity one disposed on the left side of the powder hopper, and a cavity two disposed in the side cover on the left side, wherein the side cover is installed on the powder hopper to seal the cavity one and the cavity two.

[0010] Furthermore, in this utility model, a powder inlet pipe is provided on the right side of the powder hopper, and a sleeve hole is provided on the side cover on the same side as the powder inlet pipe to fit the powder inlet pipe.

[0011] Furthermore, the powder hopper in this invention is equipped with a stirring rod connected to the gear set.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention integrates the drum core, toner cartridge, and waste toner cartridge into a single unit via side covers. Furthermore, the gear set and various rollers are designed onto the toner cartridge, optimizing both the overall size and weight of the drum unit and reducing material costs. The open space created by the side covers on both sides, compared to traditional structures, no longer restricts the volume of the toner cartridge, thus increasing its capacity.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 5The present invention preferably provides an integrated toner cartridge, including a drum core 1, a toner hopper 2, and a waste toner box 3. The drum core 1, toner hopper 2, and waste toner box 3 are integrally connected by side covers 4 on both sides. The side covers 4 form an open space 5 on the front side for the toner hopper 2 to be installed. A roller bracket 6 is integrally provided on the rear side of the toner hopper 2. A side space 7 for accommodating a gear set 11 is provided between the toner hopper 2 and the side covers 4. The side covers are symmetrically arranged on both sides of the drum core, toner hopper, and waste toner box, and are used to fix the drum core, toner hopper, and waste toner box together. The roller bracket is no longer separate but fixed to the rear side of the toner hopper for installing the various rollers. The side space is used to accommodate the gear set. Compared with the traditional structure, where the gear set is installed on the side cover or the toner cartridge shell, directly setting it on the toner hopper saves on structural costs. The open space allows the capacity and volume of the toner hopper to be unrestricted, and the front side of the toner hopper can be extended, and the top and bottom can be enlarged.

[0021] In this invention, the drum core 1, toner hopper 2, and waste toner box 3 are fixedly connected to the side cover 4 by screws. Screw holes can be pre-drilled on the side cover to secure the drum core, toner hopper, and waste toner box together.

[0022] In this invention, the toner cartridge 2 extends from the front end of an open space 5 formed by the two side covers 4 on the front side. Since there is no structural interference on the front side of the open space, the volume of the toner cartridge is not limited, and a larger volume can be designed to hold more toner.

[0023] The roller support 6 described in this utility model includes a roller mounting groove 61 located on the rear side of the powder hopper 2 for mounting the adsorption roller 12, and a roller mounting groove 62 for mounting the developing roller 13.

[0024] The side space 7 described in this invention includes a cavity 71 located on the left side of the powder hopper 2, and a cavity 72 located within a side cover 4 on the left side. The side cover 4 is installed on the powder hopper 2 to seal the cavity 71 and the cavity 72. The side space formed between the cavity 71 of the powder hopper and the cavity 72 of the side cover allows the gear set to be housed within it.

[0025] In this invention, a toner inlet pipe 21 is provided on the right side of the toner hopper 2, and a sleeve hole 22 is provided on the side cover 4 on the same side as the toner inlet pipe 21 for fitting the toner inlet pipe 21. The toner inlet pipe is used for toner feeding or discharging.

[0026] In this invention, a stirring rod 14 is provided inside the toner hopper 2 and connected to the gear set 11. The stirring rod is used to stir the toner inside the toner hopper to prevent it from condensing.

[0027] In this technical solution, the gear set 11, the adsorption roller 12, the developing roller 13, and the stirring rod 14 are all existing technologies commonly used in toner cartridges.

[0028] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
