Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and more specifically to a toner addition structure for a toner cartridge shell. Background Technology

[0002] An integrated toner cartridge is an imaging unit that integrates multiple components such as the toner drum and toner cartridge into one unit. It combines the photosensitive drum, developing unit, and toner tank into a single unit installed inside the printer. The toner transfers the image to the surface of the photosensitive drum via the internal developing unit, and then the image is fixed onto the paper through the transfer and fixing processes. The advantages of an integrated toner cartridge include easy replacement, reduced malfunctions caused by improper coordination between multiple components, strong compatibility with various printer models, and effectively improved print quality and efficiency. It is widely used in office and home printing scenarios.

[0003] Chinese Patent No. CN220962144U discloses a toner addition structure for a toner cartridge casing, belonging to the field of toner cartridge casing technology. It includes a toner cartridge casing, a photosensitive drum rotatably connected to one side of the lower end of the toner cartridge casing, a charging roller rotatably connected to the upper end of the photosensitive drum, a waste toner compartment on one side of the photosensitive drum, and a toner storage compartment on the other side of the photosensitive drum.

[0004] The existing device described above has the following problems when in use: First, the device observes the amount of toner added using a scale on a transparent plate, but when the drum casing is upright to add toner, the toner adheres to the inner wall of the transparent plate, affecting the observation. Second, the device can also observe the thickness of the re-attached toner on the scale by inserting and removing the scale. During this process, the toner attached to the scale can enter the outside air and be inhaled by the user. The toner can irritate the respiratory mucosa, causing symptoms such as coughing, sore throat, and difficulty breathing. Smaller particles may even penetrate into the lungs, causing more serious problems and seriously endangering the user's health. Third, after the drum is idle for several months, the toner may clump due to electrostatic adsorption or deposition. The device lacks a dispersion component, and when the toner clumps, printing will result in blank areas, spots, uneven color, and gray background. Summary of the Invention

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Appendix Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0024] See attached document Figures 1-4 A toner filling structure for a toner cartridge casing includes a toner cartridge casing 1. An end cap 23 is threadedly connected to one side of the casing 1. A photosensitive drum 2 is rotatably connected to the lower end of the casing 1. A charging roller 3 is positioned above the photosensitive drum 2 and rotatably connected to the inner wall of the casing 1. A waste toner compartment 4 is located inside the casing 1, situated on one side of the photosensitive drum 2. A toner storage compartment 5 is also located inside the casing 1, situated on the side of the photosensitive drum 2 furthest from the waste toner compartment 4. A developing roller 6 is rotatably connected inside the storage compartment 5. A cleaning scraper 7 is fixedly installed on the inner wall of the casing 1, positioned on one side of the charging roller 3 and above the photosensitive drum 2. A toner scraper 8 is fixedly installed inside the storage compartment 5, positioned above the developing roller 6. The upper end of the toner cartridge casing 1 has a slot, in which a transparent plate 9 is fixedly connected. A cleaning component is installed inside the toner storage compartment 5, abutting against the inner wall of the transparent plate 9. The top surface of the transparent plate 9 is marked with scale lines. The cleaning component includes a connecting rod 10, a fixing block 11, and a scraper 13. The connecting rod 10 is located inside the toner storage compartment 5, one end of which penetrates the side wall of the toner cartridge casing 1 and extends to the outside. The fixing block 11 is fixedly connected to the other end of the toner storage compartment 5. A mounting bracket 12 is fixedly connected to the periphery of the fixing block 11. A connecting plate 21 is fixedly connected to the side of the mounting bracket 12 away from the scraper 13. The connecting plate 21 has several grid holes 22. The side of the mounting bracket 12 closest to the transparent plate 9 is fixedly connected to the scraper 13, which abuts against the inner wall of the transparent plate 9. A scraping component is installed inside the toner cartridge casing 1, and the cleaning component is connected to the scraping component. A limiting component is installed on one side of the toner cartridge casing 1, connected to the cleaning component.

[0025] In this embodiment, the end cap 23 can seal the toner inlet of the toner storage chamber 5. When the operator pulls the connecting rod 10, the connecting rod 10 drives the scraper 13 to slide on the inner wall of the transparent plate 9 through the mounting bracket 12. The scraper 13 abuts against the inner wall of the transparent plate 9, so that when the scraper 13 moves up and down, it can scrape off the toner on the inner wall of the transparent plate 9, making it convenient for the operator to observe the injection volume of the toner storage chamber 5 through the scale on the transparent plate 9. At the same time, the connecting rod 10 drives the connecting plate 21 to move through the fixing block 11 and the mounting bracket 12. The connecting plate 21 drives the toner to move in the grid holes 22, thereby causing the connecting plate 21 to break up the clumps of toner.

[0026] Specifically, the scraping assembly includes a sleeve 14, a conical cylinder 15, and a conical ring 16. The sleeve 14 is fixedly connected to the inner wall of the drum housing 1. The conical cylinder 15 is located on the side of the sleeve 14 away from the drum housing 1 and is fixedly connected to the sleeve 14. The conical ring 16 is sleeved on the periphery of the connecting rod 10 and is fixedly connected to the conical cylinder 15. The connecting rod 10 passes through the conical ring 16, the conical cylinder 15, and the sleeve 14 and extends to the outside.

[0027] In this embodiment, the conical ring 16 and the conical cylinder 15 can scrape off the toner adhering to the surface of the connecting rod 10 when the personnel pull the connecting rod 10 outward, thus preventing the toner from adhering to the connecting rod 10 and entering the outside air, which would affect the health of the personnel.

[0028] Specifically, the limiting component includes a locking groove 17 and a locking block 24. The locking groove 17 is opened on the periphery of the connecting rod 10. The locking block 24 is locked with the inner wall of the locking groove 17. The bottom surface of the locking block 24 is fixedly connected to an insert rod 18. A compression spring 20 is sleeved on the periphery of the insert rod 18. A hollow column 25 is sleeved on the periphery of the insert rod 18. A clearance groove 19 is opened on the periphery of the hollow column 25. One end of the locking groove 17 abuts against the inner wall of the clearance groove 19. The other end of the locking groove 17 is fixedly connected to the bottom surface of the locking block 24. A rotating shaft 26 is fixedly connected to the side wall of the drum shell 1. The hollow column 25 is rotatably connected to the rotating shaft 26.

[0029] In this embodiment, the compression spring 20 drives the snap-fit ​​block 24 to move, so that the snap-fit ​​block 24 snaps into the snap-fit ​​groove 17, thereby limiting the movement of the connecting rod 10.

[0030] It is worth noting that the photosensitive drum 2, charging roller 3, waste toner bin 4, toner storage bin 5, developing roller 6, cleaning scraper 7, and toner scraper 8 in this utility model are all relatively mature existing technologies, so they will not be described in detail here.

[0031] The working principle and usage process of this utility model are as follows: Before adding toner, the operator first stands the drum casing 1 upright and removes the end cap 23 by unscrewing. Then, toner can be injected into the toner storage compartment 5. When the operator needs to check the toner level in the storage compartment 5, they first pull the insertion rod 18 away from the locking slot 17. The insertion rod 18 moves the locking block 24 out of the locking slot 17. The locking block 24 moves closer to the hollow column 25 and compresses the compression spring 20. When the locking block 24 is out of the locking slot 17, the operator rotates the hollow column 25, which drives the insertion rod 18 to rotate. At this time, the operator releases the insertion rod 18, and the compression spring 20 causes the locking block 24 to spring back. Next, the connecting rod 10 is limited. At this time, the personnel pull the connecting rod 10 upward. The connecting rod 10 drives the scraper 13 to slide on the inner wall of the transparent plate 9 through the mounting bracket 12, and scrapes off the toner on the inner wall of the transparent plate 9. This makes it convenient for the personnel to observe the amount of toner injected into the toner storage tank 5 from the transparent plate 9. After the toner is injected, the personnel first pull the insertion rod 18. The insertion rod 18 drives the locking block 24 to move. The locking block 24 moves and squeezes the compression spring 20. The personnel rotate the hollow column 25. The hollow column 25 drives the insertion rod 18 to rotate. When the locking block 24 is aligned with the locking groove 17, the personnel release the insertion rod 18. The compression spring 20 drives the locking block 24 to rebound. The locking block 24 inserts into the locking groove 17 and limits the connecting rod 10.

[0032] When the toner cartridge clumps up after being left for a long time, the operator repeatedly pulls the connecting rod 10 according to the above steps. The connecting rod 10 drives the connecting plate 21 to move through the fixing block 11 and the mounting bracket 12. The connecting plate 21 drives the toner to move within the grid holes 22, thereby causing the connecting plate 21 to break up the clumps of toner.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
