Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to an easy-to-refill toner cartridge. Background Technology

[0002] Currently, toner cartridges are also called photosensitive drums. They are generally composed of a base material made of aluminum and a photosensitive material coated on the base material. In laser printers, most of the imaging components are concentrated in the toner cartridge. The quality of printing is actually largely determined by the toner cartridge. Toner cartridges can be reused by filling with toner.

[0003] A refillable toner cartridge with publication number CN220691259U exhibits the following drawbacks during use: While the cartridge effectively seals the toner hopper and refill bottle, and refills toner efficiently via the elastic extension and retraction of the telescopic rod and return spring, and further aids in toner addition through the rotation of the screw feeder to prevent blockages due to low flow rates, thus improving efficiency and ease of use, the sealing mechanism of the flip-top, while functional, can lead to the flip-top falling off due to vibrations during machine operation when the device is installed inside. Therefore, we propose a refillable toner cartridge. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-refill toner cartridge, which solves the problem that the flip cover may fall off during actual use due to vibrations generated when the device is installed inside the machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An easy-to-refill toner cartridge includes a feeding tube, a partition plate fixedly installed inside the feeding tube, two arc-shaped holes on one side of the partition plate, two fan-shaped holes on another side of the partition plate, a sliding plate inside the feeding tube, two contact blocks fixedly installed on one side of the sliding plate, a sliding hole on the side of the sliding plate, and a guide rod fixedly installed on one side of the partition plate. The guide rod is located inside the feeding tube, and the sliding plate is sleeved with the guide rod through the sliding hole.

[0007] Preferably, the guide rod consists of a cylindrical part and a disc part, and a spring is sleeved on the outer wall of the cylindrical part of the guide rod. The spring is limited by the disc part of the guide rod and the sliding plate.

[0008] Preferably, an adhesive block is provided on one side of the sliding plate, and a plurality of protrusions are provided on one side of the adhesive block.

[0009] Preferably, the outer wall of the feeding pipe is provided with a first snap-fit ​​groove, and the outer wall of the feeding pipe is provided with a first fixing plate. A collection bin is fixedly installed on one side of the first fixing plate, and a first snap-fit ​​hole is provided on one side of the first fixing plate. The first fixing plate is snapped together with the feeding pipe through the first snap-fit ​​groove and the first snap-fit ​​hole.

[0010] Preferably, the outer wall of the first fixing plate is provided with a shell, a second snap-fit ​​hole is provided on one side of the shell, and a second snap-fit ​​groove is provided on the outer wall of the first fixing plate. The first fixing plate and the shell are snapped together through the second snap-fit ​​groove.

[0011] Preferably, a second fixing plate is fixedly installed on the top surface of the outer shell, and a plurality of mounting blocks are fixedly installed on the top surface of the second fixing plate.

[0012] In summary, the present invention has the following main advantages:

[0013] 1. The sliding plate design can block the two fan-shaped holes under normal circumstances, preventing powder from spilling out of the inlet if the seal falls off. When powder needs to be added, it can contact the contact block through the bottle mouth, so that the sliding plate slides along the trajectory of the guide rod, so that the fan-shaped holes can be connected, thereby ensuring that the powder enters normally.

[0014] 2. The spring design restricts the position of the sliding plate, allowing it to slide after being forced by the contact block on one side. Once the external force is released, the sliding plate returns to its original position due to the spring force, ensuring that the sliding plate can continue to pass through the blocking fan-shaped hole and maintain the sealed environment inside the device. The adhesive block design creates a protrusion on the surface of the sliding plate, preventing powder residue from remaining on the surface due to an overly smooth surface. Furthermore, the height of the adhesive block itself reduces the impact of any small gaps between the partition plate and the sliding plate on the device. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figures 1-3 An easy-to-add toner cartridge includes a feeding tube 1. A partition plate 2 is fixedly installed inside the feeding tube 1. Two arc-shaped holes 3 and two fan-shaped holes 4 are opened on one side of the partition plate 2. A sliding plate 5 is provided inside the feeding tube 1. Two contact blocks 6 are fixedly installed on one side of the sliding plate 5. A sliding hole 7 is opened on the side of the sliding plate 5. A guide rod 8 is fixedly installed on one side of the partition plate 2. The guide rod 8 is located inside the feeding tube 1. The sliding plate 5 is sleeved with the guide rod 8 through the sliding hole 7. Under normal circumstances, the sliding plate 5 can block the two fan-shaped holes 4 to prevent the powder from spilling out of the feed port when the seal falls off. When powder needs to be added, it can contact the contact blocks 6 through the bottle mouth, so that the sliding plate 5 slides along the trajectory of the guide rod 8, so that the fan-shaped holes 4 can be in a connected state, thereby ensuring that the powder enters normally.

[0021] The guide rod 8 consists of a cylindrical part and a disc part. A spring 9 is fitted on the outer wall of the cylindrical part of the guide rod 8. The spring 9 limits the position of the sliding plate 5 through the disc part of the guide rod 8. The design of the spring 9 restricts the position of the sliding plate 5, so that after the sliding plate 5 slides due to the force on the contact block 6 on one side, the sliding plate 5 can return to its original position due to the elastic force of the spring 9 after the external force is released. This ensures that the sliding plate 5 can continue to pass through the blocking fan-shaped hole 4 to ensure the airtight environment inside the device. An adhesive block 10 is provided on one side of the sliding plate 5. The adhesive block 10 has several protrusions on one side. This design disrupts the smooth surface structure, reducing the probability of powder sticking to the sliding plate 5 during powder addition and minimizing unnecessary losses. The outer wall of the feeding pipe 1 has a first retaining groove 11, and a first fixing plate 12 is provided on its outer wall. A collection bin 13 is fixedly installed on one side of the first fixing plate 12. The collection bin 13 allows for the centralized collection of large amounts of powder, serving as the main storage element of the device. To ensure the normal operation of the drum, a first locking hole 14 is provided on one side of the first fixing plate 12. The first fixing plate 12 is locked together with the feed tube 1 through the first locking groove 11 and the first locking hole 14. A shell 15 is provided on the outer wall of the first fixing plate 12. A second locking hole 16 is provided on one side of the shell 15. A second locking groove 17 is provided on the outer wall of the first fixing plate 12. The first fixing plate 12 and the shell 15 are locked together through the second locking groove 17. The design of the second locking groove 17 allows the first fixing plate 12 and the shell 15 to be locked together, which facilitates the disassembly of the whole assembly of the first fixing plate 12 and the collection chamber 13 at any time, reducing the time cost required for replacing parts. A second fixing plate 18 is fixedly installed on the top surface of the shell 15. Several mounting blocks 19 are fixedly installed on the top surface of the second fixing plate 18. The design of the second fixing plate 18 and the mounting blocks 19 facilitates the connection between the shell 15 and the printer body, making it as convenient as possible to disassemble and install the device body while ensuring installation stability.
