Description

Technical Field

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

[0002] Toner cartridges are essential printing consumables in printers, crucial for the printing process. Due to high demand, cost control is paramount, especially regarding their structural design. Traditional toner cartridges separate the toner storage compartment and the developer compartment into two components, which has several drawbacks, such as: 1. A wide variety of materials and complex production and assembly processes. 2. Complex engineering requiring multiple equipment and molds for production. 3. Lengthy and complex quality control processes, increasing costs and difficulties. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a structure that combines the toner storage chamber and the developing chamber inside the toner cartridge into a single unit.

[0004] To achieve the above objectives, this utility model provides the following solution: An integrated toner cartridge supply structure includes a toner cartridge containing a toner storage compartment and a developing compartment. The toner cartridge is composed of the toner storage compartment and the developing compartment as a single unit. An integrated cover is provided on the toner cartridge that can simultaneously seal the toner storage compartment and the developing compartment. A toner outlet is provided inside the toner cartridge. A wire bonding groove is provided at the top of the toner outlet and at the bottom of the integrated cover. Connecting components are provided on the toner cartridge and the integrated cover.

[0005] Furthermore, in this utility model, the powder storage chamber and the developing chamber are integrally formed by injection molding, and the powder storage chamber and the developing chamber are internally connected.

[0006] Furthermore, the integrated cover in this utility model consists of a rear cover and a front cover, which correspond to the top of the powder storage chamber and the developing chamber, respectively.

[0007] Furthermore, in this invention, the powder outlet is located between the powder storage chamber and the developing chamber.

[0008] Furthermore, in this utility model, the two ends of the welding groove of the powder outlet are bent backward, the welding groove of the integrated cover is arranged around the periphery, and the welding groove of the powder outlet and the welding groove of the integrated cover are directly opposite each other.

[0009] Furthermore, the connecting component in this utility model includes screw posts disposed on the left and right sides of the bottom of the integrated cover, and screw holes disposed on the left and right sides of the toner cartridge. The screw posts are inserted into the screw holes and fixed by screws.

[0010] Furthermore, the top of the one-piece cover in this utility model is provided with a hand grip groove.

[0011] In summary, the advantages of this utility model over the prior art are: This invention simplifies the structure of the powder storage chamber and the developing chamber. By using a one-piece molding process, the structure of the powder storage chamber and the developing chamber no longer needs to be divided into multiple components, offering the following advantages: 1. Significantly reduces the types of materials, correspondingly reducing material storage space and management costs. 2. Reduces the number of equipment and molds used in the production process, decreasing post-assembly steps and simplifying processes, thus better reducing production costs and quality control difficulties. 3. Due to the one-piece molding, the components have higher precision and strength, the material quality is more stable, and the number of quality control points is reduced, directly improving the quality of the finished product.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5The present invention preferably provides an integrated toner cartridge toner supply structure, including a toner cartridge 1, a toner storage compartment 11 and a developing compartment 12 disposed inside the toner cartridge 1, the toner cartridge 1 being integrally composed of the toner storage compartment 11 and the developing compartment 12, an integrated cover 2 on the toner cartridge 1 that can simultaneously cover the toner storage compartment 11 and the developing compartment 12, a toner outlet 3 disposed inside the toner cartridge 1, a wire bonding groove 4 disposed at the top of the toner outlet 3 and at the bottom of the integrated cover 2, and connecting components 5 disposed on the toner cartridge 1 and the integrated cover 2. The toner cartridge and developing chamber are integrated into one unit, whereas traditionally these are separate components. Various accessories, such as inserts, clips, and even screws and nuts, are used at the assembly points. This design employs a one-piece molding process, significantly reducing the number of accessories required for connecting the toner cartridge and developing chamber. The integrated cover increases the coverage area, allowing for a closer fit to the integrated structure of the toner cartridge and developing chamber during assembly. The bonding wires are concealed within the bonding grooves in conjunction with the toner cartridge, demonstrating a rational design. Furthermore, the integrated cover is mounted on the toner cartridge via connecting components. Both the toner cartridge and the integrated cover feature multiple reinforcing ribs to enhance structural strength.

[0014] In this invention, the powder storage chamber 11 and the developing chamber 12 are integrally formed by injection molding, and their interiors are connected. In conventional structures, the powder storage chamber and the developing chamber are not integral; however, in this integrated design, their interiors remain connected via the powder outlet.

[0015] The integrated cover 2 of this invention consists of a rear cover 21 and a front cover 22, which correspond to the tops of the powder storage chamber 11 and the developing chamber 12, respectively. The front cover is used to cover the top of the developing chamber, serving as a support for the top of the developing chamber in a conventional structure.

[0016] In this invention, the powder outlet 3 is located between the powder storage chamber 11 and the developing chamber 12. The powder outlet stores powder in the powder storage chamber and then transfers it to the developing chamber for use.

[0017] In this invention, the welding groove 4 of the powder outlet 3 is bent backward at both ends, and the welding groove 4 of the integrated cover 2 is arranged around the periphery. The welding groove 4 of the powder outlet 3 and the welding groove 4 of the integrated cover 2 are directly opposite each other. The welding groove is designed at the top of the powder outlet and the bottom of the integrated cover to form a welding groove, leaving groove-shaped space to accommodate the installation of the welding wire.

[0018] The connecting component 5 of this utility model includes screw posts 51 disposed on the left and right sides of the bottom of the integrated cover 2, and screw holes 52 disposed on the left and right sides of the toner cartridge 1. The screw posts 51 are inserted into the screw holes 52 and fixed by screws. When the integrated cover is installed into the toner cartridge, the screw posts are inserted into the screw holes and screws are screwed in under the screw holes to achieve installation and fixation.

[0019] The one-piece cover 2 of this utility model is provided with a hand grip groove 6 on the top, which makes it convenient for people to hold and operate.

[0020] 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.
