Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to a selenium cartridge powder leakage prevention structure. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. In laser printers, imaging components are mostly concentrated in the toner cartridge, and the quality of printing is actually largely determined by the toner cartridge. A toner cartridge structure that prevents leakage of powder is recorded in the patent with the existing patent announcement number CN216286164U, in which a positioning column is provided on the shell, and a second positioning hole that matches the cross-sectional shape of the positioning column is provided on the end cover. When the end cover is fixed to the end of the shell by a locking member, the positioning column can pass through the second positioning hole. At this time, the outer wall of the positioning column abuts against the inner wall of the second positioning hole to form a limit fit between the two, and the first positioning hole and the threaded hole located on the same axis can prevent the locking member from passing through the first positioning hole and the threaded hole in sequence. Deviations are generated, making the fixation of the end cover more stable. In the process of introducing toner into the powder bin, the toner will be blocked in the channel due to agglomeration, which brings inconvenience to the addition of toner, and affects the sealing effect of the toner, thereby causing a decrease in the quality of the toner cartridge when it is sealed.

[0003] Based on this, a toner cartridge anti-leakage powder structure is now provided to eliminate the drawbacks of the existing device. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] In one embodiment, Figure 1-Figure 5 As shown, a toner cartridge anti-leakage powder structure comprises an outer shell 11, a powder bin 12 is installed inside the outer shell 11, a fixed tube 13 is fixedly installed at one end of the powder bin 12, a movable tube 15 is installed inside the fixed tube 13, and one end of the movable tube 15 extends to the outside of the outer shell 11; a powder passing assembly is arranged at one end of the fixed tube 13 close to the powder bin 12, so as to prevent agglomerated carbon powder from being blocked inside the fixed tube 13; a sealing assembly is arranged at one end of the movable tube 15 extending to the outside of the outer shell 11, so as to prevent carbon powder from leaking out; a limiting assembly is fixedly installed on the outer wall of the movable tube 15, so as to prevent the fixed tube 13 and the movable tube 15 from being separated from each other.

[0026] In this embodiment, the sealing component is opened, and carbon powder is added to the powder bin 12 through a powder adding tool. The agglomerated carbon powder will be blocked in the fixed tube 13. The agglomerated carbon powder is crushed by the powder passing component and pushed into the powder bin 12. The fixed tube 13 and the movable tube 15 are prevented from being separated from each other and the carbon powder is prevented from leaking out by the limiting component. After the carbon powder is added, the movable tube 15 is sealed by the sealing component to prevent the carbon powder from leaking out.

[0027] In one embodiment, Figure 4 As shown, the macaron assembly includes a macaron groove 14 and a macaron block 18. The macaron groove 14 is opened at one end of the fixed tube 13 close to the powder bin 12, and the macaron block 18 is fixedly installed at one end of the movable tube 15 close to the macaron groove 14. The macaron groove 14 matches the macaron block 18.

[0028] When the agglomerated carbon powder is blocked inside the fixed tube 13 , the movable tube 15 and the powder block 18 move inside the fixed tube 13 to squeeze and crush the agglomerated carbon powder, and the powder block 18 discharges the crushed carbon powder into the powder bin 12 through the powder slot 14 .

[0029] In one embodiment, Figure 3 and Figure 5 As shown, the sealing assembly includes a sealing cover 21, which is installed at one end of the movable tube 15 extending to the outside of the outer shell 11, the outer wall of the sealing cover 21 is provided with an external thread, the inner wall of the movable tube 15 is provided with an internal thread matching the external thread of the sealing cover 21, the sealing cover 21 is threadedly connected to the inner wall of the movable tube 15, and a screw head 22 is fixedly installed at one end of the sealing cover 21 away from the movable tube 15.

[0030] By fixing a screw head 22 on the end of the sealing cover 21 away from the movable tube 15, it is convenient for the staff to screw the sealing cover 21 so that the external thread of the sealing cover 21 is threadedly connected with the internal thread of the movable tube 15. The sealing cover 21 seals the end of the movable tube 15 located outside the outer shell 11 to prevent leakage of carbon powder.

[0031] In one embodiment, Figure 4 and Figure 5 As shown, the limiting assembly includes a limiting ring 17, which is fixedly sleeved on the outer wall of the movable tube 15, and a sliding groove matching the limiting ring 17 is opened inside the fixed tube 13, and a rebound unit is fixedly installed between the limiting ring 17 and the inner wall of the fixed tube 13.

[0032] The movable tube 15 slides inside the fixed tube 13 , thereby driving the limiting ring 17 to slide inside the slide groove. Therefore, due to the limiting effect of the limiting ring 17 , the movable tube 15 and the fixed tube 13 are prevented from being separated from each other.

[0033] In one embodiment, Figure 4 and Figure 5 As shown, the rebound unit includes a spring 16 , one end of the spring 16 is fixed to the inner wall of the fixed tube 13 , and the other end of the spring 16 is fixedly connected to the limiting ring 17 .

[0034] By pulling the movable tube 15, the spring 16 contracts, so that the powder block 18 is moved away from the powder groove 14, so that the carbon powder can enter the powder bin 12 through the powder groove 14; when the spring 16 rebounds, the powder block 18 is embedded in the powder groove 14 under the elastic force of the spring 16, thereby closing the powder groove 14 to prevent the carbon powder from leaking out.

[0035] In one embodiment, Figure 1 and Figure 2 As shown, a pull ring 19 is installed on the outer wall of the movable tube 15 , and the pull ring 19 is located outside the outer shell 11 .

[0036] By installing a pull ring 19 on the outer wall of the movable tube 15, it is convenient for the staff to pull the movable tube 15 through the pull ring 19, so that the movable tube 15 can slide inside the fixed tube 13, ensuring that the structure can work stably.

[0037] In one embodiment, Figure 4 As shown, the thickness of the macaroni block 18 is greater than the thickness of the macaroni groove 14 .

[0038] By designing the thickness of the macaron block 18 to be greater than the thickness of the macaron groove 14 , the embedding effect between the macaron block 18 and the macaron groove 14 is ensured, so that the macaron groove 14 can be completely closed to prevent carbon powder from leaking out.

[0039] In one embodiment, Figure 4 and Figure 5 As shown, a rubber pad 20 is provided between the limiting ring 17 and the inner wall of the fixing tube 13 .

[0040] The rubber pad 20 is soft and has a certain buffering effect, thereby preventing the limit ring 17 and the inner wall of the fixed tube 13 from being damaged when the spring 16 rebounds, thereby affecting the leakage-proof effect of the carbon powder.

[0041] The above embodiment discloses a toner cartridge anti-leakage powder structure, wherein the staff moves the sealing cover 21 and the movable tube 15 away from each other by screwing the head 22, and pulls the movable tube 15 by the pull ring 19, so that the spring 16 contracts, and then the powder block 18 moves away from the powder groove 14, and carbon powder is added to the powder bin 12 by the powder adding tool, and the carbon powder enters the powder bin 12 through the powder groove 14. When the agglomerated carbon powder is blocked in the fixed tube 13, the movable tube 15 and the powder block 18 move in the fixed tube 13, so as to squeeze and crush the agglomerated carbon powder, and the powder block 18 discharges the crushed carbon powder into the powder bin 12 through the powder groove 14. After the carbon powder is added, the spring 16 rebounds, and the powder block 18 is embedded in the powder groove 14 under the elastic force of the spring 16, and then the powder groove 14 is closed to prevent the carbon powder from leaking out. The staff closes the movable tube 15 with the sealing cover 21 by screwing the head 22 to prevent the carbon powder from leaking out.

[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
