Description

Technical Field

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

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of a base material made of aluminum and a photosensitive material coated on the base material. In laser printers, the print quality is largely determined by the toner cartridge. The toner cartridge not only determines the print quality but also the amount of money the user needs to spend during use.

[0003] When adding toner to a toner cartridge, the toner needs to be poured from the toner cartridge into the toner storage box inside the cartridge. During the pouring process, the toner will be scattered in the air. The dangers of spilled toner should not be underestimated. It can not only contaminate the printer's internal circuitry and gears, causing short circuits, paper jams, or reduced print quality, but it can also pose a threat to human health. For example, if toner particles are inhaled into the respiratory tract, they may cause lung inflammation or allergies, and long-term exposure may even increase the risk of cancer. Utility Model Content

[0004] Therefore, it is necessary to provide an integrated toner cartridge assembly to address the issue of toner scattering through the air vents during the pouring process from the toner cartridge into the toner storage box of the toner drum.

[0005] An integrated toner cartridge assembly, characterized in that it comprises: a toner cartridge assembly body, a toner storage box fixedly connected to the upper side of one side of the toner cartridge assembly body, a feed tube fixedly inserted into the inside of the toner storage box, and a dispensing box movably disposed above the feed tube;

[0006] A sealing assembly is disposed inside the powder storage box and located in the middle of the feed pipe to facilitate sealing of the feed pipe.

[0007] In one embodiment, the diameter of the lower outlet end of the dispensing box is smaller than the inner diameter of the feed pipe, and the outlet end of the dispensing box is inserted into the interior of the feed pipe and extends downward.

[0008] In one embodiment, a cover plate is magnetically attached to the inner wall of the powder storage box, and one side of the cover plate is threadedly connected to the surface of the feed pipe.

[0009] In one embodiment, one side of the dispensing box slides along one outer wall of the powder storage box, and one side of the dispensing box is embedded inside the powder storage box.

[0010] In one embodiment, the sealing assembly includes two lead screws located inside the powder storage box, a transmission assembly is provided between the two lead screws, one end of one of the lead screws is fixedly connected to a motor, and the surfaces of the two lead screws are threaded with sliders. A sealing gasket is provided on the side of the two sliders that are close to each other, and the sealing gasket is located inside the feed pipe and slides.

[0011] In one embodiment, a notch is provided on one side of the powder storage box, and one side of the sealing gasket covers the notch.

[0012] In one embodiment, two top plates are movably connected to the sides of the two sliders that are close to each other, and a telescopic rod is movably connected to the sides of the two top plates that are close to each other. The sides of the two top plates that are far apart from each other are in contact with the inner wall of the sealing gasket.

[0013] Beneficial effects

[0014] 1. The drum unit itself, as the core component of the entire assembly, integrates key components such as the photosensitive drum, charging roller, and developing roller. It is responsible for electrostatic imaging and toner transfer during the printing process. A toner storage box is fixedly connected to the upper side of the drum unit to store the toner required for printing, ensuring the continuity and stability of the printing process. A feed tube is fixedly inserted inside the toner storage box, serving as the channel for toner to enter the storage box from the dispensing box. Its design must ensure smooth toner flow and airtightness. A dispensing box is movable above the feed tube for temporarily storing toner to be added, facilitating toner replenishment, reducing toner leakage, and improving safety during toner addition.

[0015] 2. The toner cartridge assembly also features a sealing component located inside the toner storage box and in the middle of the feed pipe. Similar to a valve structure, it controls the opening and closing of the feed pipe. During toner refilling, the sealing component effectively prevents toner leakage, ensuring a clean and efficient process. When toner needs to be added, the user simply pours the toner from the dispensing box into the toner storage box through the feed pipe and controls the opening and closing of the feed pipe by operating the sealing component. This design not only simplifies the toner refilling process but also improves safety during the process. Attached Figure Description

[0028] The following is combined with Figures 1-4 This invention describes an integrated, one-piece toner cartridge assembly.

[0029] In one embodiment, an integrated toner cartridge assembly includes: a toner cartridge assembly body 100 and a sealing assembly 400. A toner storage box 101 is fixedly connected to the upper side of one side of the toner cartridge assembly body 100. A feed tube 102 is fixedly inserted into the inside of the toner storage box 101. A dispensing box 200 is movably disposed above the feed tube 102. The sealing assembly 400 is disposed inside the toner storage box 101 and located in the middle of the feed tube 102 to facilitate sealing of the feed tube 102.

[0030] In this embodiment, the drum assembly body 100, as the core part of the entire assembly, integrates key components such as the photosensitive drum, charging roller, and developing roller, and is responsible for realizing electrostatic imaging and toner transfer functions during the printing process. A toner storage box 101 is fixedly connected to the upper side of the drum assembly body 100 to store the toner required for printing, ensuring the continuity and stability of the printing process.

[0031] A feed pipe 102 is fixedly inserted into the inside of the toner storage box 101, serving as the channel for toner to enter the toner storage box 101 from the dispensing box 200. Its design must ensure smooth toner flow and airtightness. The dispensing box 200 is movably installed above the feed pipe 102 for temporarily storing toner to be added, facilitating toner replenishment operations for users.

[0032] In addition, the component also includes a sealing component 400, which is located inside the toner storage box 101 and in the middle of the feed pipe 102. Similar to a valve structure, it can control the opening and closing of the feed pipe 102. During the toner addition process, the sealing component 400 can effectively prevent toner leakage and ensure the cleanliness and efficiency of the addition process. When toner needs to be added, the user only needs to pour the toner in the dispensing box 200 into the toner storage box 101 through the feed pipe 102, and control the opening and closing of the feed pipe 102 by operating the sealing component 400 to complete the toner replenishment. This design not only simplifies the toner addition process, but also improves the safety of the toner addition process.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the diameter of the lower outlet end of the dispensing box 200 is smaller than the inner diameter of the feed pipe 102. The outlet end of the dispensing box 200 is inserted into the inside of the feed pipe 102 and extends downward. A cover plate 300 is magnetically attached to the inner wall of the powder storage box 101. One side of the cover plate 300 is threadedly connected to the surface of the feed pipe 102. One side of the dispensing box 200 slides along one side of the outer wall of the powder storage box 101. One side of the dispensing box 200 is embedded in the inside of the powder storage box 101.

[0034] In this embodiment, the constricted design of the dispensing box 200 forms a physical limiting structure through the diameter difference. Combined with the extension section, it can penetrate deep into the inner wall of the feed pipe 102 to form a guiding channel, which not only prevents the toner from overflowing when poured but also reduces residue on the pipe wall. The magnetic cover plate 300 achieves quick pre-positioning through embedded magnets. The threaded connection end of the magnetic cover plate 300 adopts a fine thread structure, which gradually presses the feed pipe 102 interface during the rotation and closing process, forming a double sealing guarantee with the magnetic attraction. This magnetic attraction plus threaded composite fixing method retains the convenience of quick disassembly and assembly, and enhances the vibration resistance through mechanical interlocking. When the dispensing box 200 is removed, the feed pipe 102 is protected by the magnetic cover plate 300, which improves the sealing reliability while ensuring the convenience of operation.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the sealing assembly 400 includes a lead screw 403 located inside the powder storage box 101. There are two lead screws 403, and a transmission assembly 402 is provided between the two lead screws 403. One end of one of the lead screws 403 is fixedly connected to a motor 401. The surfaces of the two lead screws 403 are threaded with sliders 404. A sealing gasket 405 is provided on the side of the two sliders 404 that are close to each other. The sealing gasket 405 slides inside the feed pipe 102.

[0036] In this embodiment, the sealing assembly 400 achieves precise translation control of the sealing gasket 405 through a double lead screw 403 structure. When the motor 401 drives the lead screw 403 to rotate, the transmission assembly 402 synchronously drives another set of lead screws 403 to rotate, ensuring that the sliders 404 on both sides maintain the same speed and direction of movement, so that the sealing gasket 405 opens and closes smoothly along the axial direction in the feed tube 102. The sealing gasket 405 is made of silicone material and has a double-layer corrugated pleated structure, which can form a line contact seal with the inner wall of the feed tube 102 when closed, and can also compensate for processing errors through elastic deformation. Its surface is coated with Teflon coating to reduce toner adhesion. Combined with the mechanical self-locking characteristics of the lead screw 403, it can still maintain a sealed state in the power-off state. Compared with traditional manual valves, this electric sealing mechanism can accurately control the opening of the feed tube 102, avoid accidental leakage during the toner addition process, and the integrated design reduces external operating parts and optimizes the internal space utilization of the toner storage box 101.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, a notch is provided on one side of the powder storage box 101, and the notch is covered by one side of the sealing gasket 405. Two top plates 406 are movably connected to the side of the two sliders 404 that are close to each other. A telescopic rod 407 is movably connected to the side of the two top plates 406 that are close to each other. The side of the two top plates 406 that are far apart from each other is in contact with the inner wall of the sealing gasket 405.

[0038] In this embodiment, the sealing gasket 405 fits tightly against the edge of the notch in the powder storage box 101 through elastic deformation to prevent dust diffusion. The top plate 406 adopts a wedge-shaped design, which, supported by the telescopic rod 407, can apply uniform pressure to the sealing gasket 405 to compensate for material creep after long-term use and ensure continuous sealing interface. The telescopic rod 407 has a built-in spring reset mechanism to maintain the pre-tightening force of the top plate 406 on the sealing gasket 405. This multi-stage sealing structure improves the sealing performance of the powder storage box 101 by combining mechanical pressurization with material self-adaptation, while extending the service life of the sealing assembly 400.

[0039] Working principle:

[0040] This component enables electrostatic imaging and toner transfer during the printing process via the drum unit body 100. The toner storage box 101 fixed above it stores toner, ensuring continuous printing. When adding toner, the feed box 200, with its constricted design, is inserted into the feed tube 102 to form a guide channel, preventing toner spillage. The user operates the sealing component 400, where the motor 401 drives the lead screw 403 to rotate. Synchronously driven by the transmission component 402, the sliders 404 on both sides move the sealing gasket 405 axially within the feed tube 102, controlling the opening and closing of the channel. The sealing gasket 405 is made of silicone and has a double-layer design. The corrugated structure forms a line contact seal with the inner wall of the feed pipe 102. The Teflon coating on its surface reduces toner adhesion. At the same time, the top plate 406, supported by the telescopic rod 407, applies uniform pressure to the sealing gasket 405 to compensate for material creep and maintain continuous sealing interface. The entire process is precisely controlled by the electric sealing mechanism to prevent toner leakage. The magnetic cover plate 300 protects the feed pipe 102 after the distribution box 200 is removed, ensuring convenient operation and reliable sealing. This greatly reduces the possibility of toner leakage, reduces pollution to the surrounding environment, and reduces harm to human health.

[0041] It should be noted that the toner cartridge assembly body 100 and motor 401 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the toner cartridge assembly body 100 and motor 401 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
