Description

Technical Field

[0001] This utility model relates to the field of printer toner cartridge technology, and in particular to a high heat dissipation printer toner cartridge. Background Technology

[0002] The printer drum unit is the core imaging component in laser printing equipment, mainly composed of a photosensitive drum core, toner cartridge, drive assembly, and housing. During operation, the photosensitive drum core completes image transfer under high-voltage electrostatic force, making high-speed contact with toner particles and printing paper while continuously rotating. Although the drum unit does not have an active heating function, in continuous printing, high-volume output, or high-temperature environments, the drum core assembly and its surrounding structure can still experience localized temperature increases due to friction, heat conduction, and accumulated heat from the environment.

[0003] Some printers currently use cooling fans and ventilation holes inside the main unit to dissipate heat, but most toner cartridges do not have a dedicated heat dissipation path. The heat inside the cartridge is often trapped between the drum core or the shell and is difficult to release quickly. Especially in mid-to-high-end office printing equipment or industrial high-speed laser printing scenarios, the temperature rise of the drum body will affect the stability and lifespan of the coating on the surface of the photosensitive drum. Utility Model Content

[0004] Therefore, it is necessary to address the issue that most toner cartridge structures lack dedicated heat dissipation paths, causing internal heat to often remain trapped between the drum core and the housing, making rapid heat dissipation difficult. This is especially problematic in mid-to-high-end office printing equipment or high-speed industrial laser printing scenarios, where drum temperature rise affects the stability and lifespan of the photosensitive drum surface coating. To address this, a high-heat-dissipation printer toner cartridge is provided, comprising: a toner cartridge fixedly installed inside the printer, with an ink cartridge fixedly installed on one side and a drum core rotatably installed on the other side; a heat dissipation printing mechanism, located on one side of the toner cartridge for dissipating heat from the high-intensity working drum core; wherein the heat dissipation printing mechanism includes a heat-conducting plate fixedly installed inside the toner cartridge, a heat dissipation component on the outer side of the heat-conducting plate, and auxiliary components for assisting heat dissipation on the outer side of the heat dissipation component.

[0005] The heat dissipation assembly includes a mounting bracket fixedly installed on the outside of the drum. Multiple fins are fixedly installed on one side of the mounting bracket, and one side of each of the multiple fins extends into the interior of the drum and is fixedly connected to a heat-conducting plate.

[0006] The multiple fins are equidistantly distributed, the heat-conducting plate is set in an arc shape, and the heat-conducting plate is located on one side of the drum core.

[0007] The surface of the drum has multiple ventilation holes, all of which are located on one side of the fins.

[0008] A temperature-sensitive color-changing plate is fixedly installed on the surface of the toner cartridge, and the temperature-sensitive color-changing plate is fixedly connected to one side of the heat-conducting plate.

[0009] The auxiliary components include a fan located on top of the toner cartridge, with multiple fixed covers fixedly installed at the bottom of the fan, and an air outlet pipe fixedly installed inside the fixed covers. The multiple fixed covers are all located on top of multiple fins.

[0010] The fixed cover is slidably sleeved on the top of the adjacent fin, and the air outlet is located on the top of the adjacent fin.

[0011] The surface of the fin has a through-hole, one end of which is connected to the heat-conducting plate, and one end of the air outlet pipe adjacent to the fin extends into the corresponding through-hole.

[0012] Beneficial effects

[0013] 1. During use, the drum core continuously generates heat through operation. This heat is quickly conducted to the heat dissipation components via the heat-conducting plate, preventing heat accumulation inside the drum, improving the thermal stability of the drum core, and delaying the aging of the photosensitive layer. The auxiliary components have a pluggable structure and can be flexibly installed according to the temperature rise. Their built-in heat-conducting components or heat dissipation structures further enhance the heat dissipation effect, ensuring that heat is released in a timely manner under high-load printing conditions.

[0014] 2. When the fan is working, it generates airflow, which is directed directly to the top of the fins through the air outlet pipe, so that a high-speed heat exchange zone is formed between the fins and the outside air, which significantly improves the heat removal speed. The fan can start when the drum core temperature is high, forming a superposition effect with the original natural convection heat dissipation path, and improving the peak heat dissipation capacity.

[0027] The following is combined with Figures 1-4 This invention describes a high-heat-dissipation printer toner cartridge.

[0028] In one embodiment, a high-heat-dissipation printer drum includes: a drum 100 fixedly installed inside the printer, an ink cartridge 110 fixedly installed on one side of the drum 100, and a drum core 200 rotatably installed on the other side of the drum 100; a heat dissipation printing mechanism 300, which is disposed on one side of the drum 100 for dissipating heat from the drum core 200 under high-intensity operation; wherein the heat dissipation printing mechanism 300 includes a heat-conducting plate 310 fixedly installed inside the drum 100, a heat dissipation component 320 disposed on the outer side of the heat-conducting plate 310, and an auxiliary component 330 disposed on the outer side of the heat dissipation component 320 for assisting heat dissipation.

[0029] In this embodiment, during use, the drum core 200, operating under high intensity, continuously generates heat. This heat can be rapidly conducted to the heat dissipation assembly 320 via the heat-conducting plate 310, thereby preventing heat accumulation inside the drum 100, improving the thermal stability of the drum core 200, and delaying the aging of its photosensitive layer. The auxiliary assembly 330 is an externally connectable structural component, using a plug-in installation method, which can be quickly installed or removed according to actual operating temperature requirements. When the drum core 200 operates continuously for a long time, causing heat to be unable to be released in time through the heat dissipation assembly 320, the auxiliary assembly 330 can act as an enhanced heat dissipation unit, further enhancing the heat diffusion effect through its built-in heat-conducting components or heat dissipation windows.

[0030] It should be noted that some toner cartridges 100 typically include an ink cartridge 110 for carrying toner, a drum core 200 for image imaging, a drive gear, a rotating shaft assembly, and positioning clips and electrode contact structures adapted to the printer host. The entire cartridge is encapsulated in a single unit and is inserted into the printer's internal guide rail assembly via end-slot structures. A heat-conducting plate 310 is located in the cavity between the drum core 200 and the housing, and is attached to the inner shell via a thin metal plate. This design does not alter the original size, weight, or installation method of the toner cartridge 100, and it still allows for smooth integration with the printer host's guide rails. For easy connection, the heat dissipation component 320 is located on the outside of the heat conduction plate 310. The installation position is in the non-transmission surface area of ​​the toner cartridge 100 housing. The structure is a thin heat conduction fin or metal heat conduction plate 310 that is close to the outer wall of the housing. It does not protrude from the original installation boundary of the toner cartridge 100 and will not interfere with the plugging and unplugging of it with the printer guide rail or the paper feed path. The auxiliary component 330 is a detachable structure and is located on the outside of the side wall of the toner cartridge 100 housing. The specific position is far away from the main drive end, contact end and paper output channel, so as not to affect its installation posture and stable operation in the printer.

[0031] like Figure 2 and Figure 3 As shown, the heat dissipation assembly 320 includes a mounting bracket 321 fixedly installed on the outside of the drum 100. Multiple fins 322 are fixedly installed on one side of the mounting bracket 321. One side of each of the multiple fins 322 extends into the interior of the drum 100 and is fixedly connected to the heat conduction plate 310.

[0032] In this embodiment, by extending one side of multiple fins 322 into the interior of the drum 100 and fixing them to the heat-conducting plate 310, a continuous heat dissipation path is formed, which is transferred from the heat-conducting plate 310 to the fins 322 and then diffuses outward. This can efficiently conduct the heat generated by the drum core 200 during high-intensity operation to the outside of the drum 100, effectively improving the overall heat dissipation efficiency, increasing the contact area with the outside air, and using natural convection to achieve rapid heat dissipation, preventing the surface of the drum core 200 from aging of the photosensitive material or abnormal imaging due to overheating.

[0033] Multiple fins 322 are equidistantly distributed, and the heat-conducting plate 310 is set in an arc shape and is located on one side of the drum core 200.

[0034] In this embodiment, the multiple fins 322 are equidistantly distributed, achieving uniform heat release during the heat dissipation process. The arc shape of the heat-conducting plate 310, which is fitted to one side of the drum core 200, can maximize the heat-conducting contact area between the plate and the drum core 200 without affecting the normal rotation of the drum core 200, thereby improving the heat conduction efficiency. This arc-fitting design allows the heat generated by the drum core 200 during high-speed operation to be quickly conducted to the heat-conducting plate 310, and further released into the outside air by the equidistantly arranged fins 322, forming a stable and continuous passive heat dissipation path.

[0035] The surface of the drum 100 has multiple ventilation holes 323, all of which are located on one side of the fin 322.

[0036] In this embodiment, the fins 322 dissipate heat to the outside based on the heat conduction of the heat plate 310, while the ventilation holes 323 provide a channel for airflow. In conjunction with natural convection or airflow movement inside the printer, the hot air gathered near the fins 322 can be continuously removed, preventing heat from accumulating in the heat dissipation area and effectively improving the overall heat dissipation efficiency. The ventilation holes 323 are set in a position that precisely avoids the imaging area of ​​the drum core 200 and the sealing area of ​​the toner cartridge, so that they do not affect the sealing performance of the drum 100 or interfere with the image imaging accuracy.

[0037] A thermosensitive color-changing plate 324 is fixedly installed on the surface of the toner cartridge 100, and the thermosensitive color-changing plate 324 is fixedly connected to one side of the heat-conducting plate 310.

[0038] In this embodiment, the temperature-sensitive color-changing plate 324 is set at a key position in the heat conduction path, which can accurately sense the temperature change transmitted by the heat conduction plate 310, and automatically change color when the temperature exceeds the set threshold, providing users with an intuitive high temperature warning.

[0039] like Figure 2 and Figure 4 As shown, the auxiliary component 330 includes a fan 331 disposed on the top of the drum 100. Multiple fixed covers 332 are fixedly installed on the bottom of the fan 331. An air outlet pipe 333 is fixedly installed inside the fixed cover 332. The multiple fixed covers 332 are all located on the top of multiple fins 322.

[0040] In this embodiment, the fan 331 generates airflow when it is working, and directs the airflow directly to the top of the fins 322 through the air outlet pipe 333, so that the fins 322 and the outside air form a high-speed heat exchange zone, which significantly improves the heat removal speed. The fan 331 can be started when the temperature of the drum core 200 is high, forming a superposition effect with the original natural convection heat dissipation path, and improving the peak heat dissipation capacity.

[0041] The fixed cover 332 is slidably sleeved on the top of the adjacent fin 322, and the air outlet pipe 333 is located on the top of the adjacent fin 322.

[0042] In this embodiment, the fixed cover 332 is installed between the fins 322 by sliding fit, which facilitates installation and disassembly. The air outlet pipe 333 is set on the top of the adjacent fins 322, so that the air outlet path can be guided along the gap between the fins 322, thereby maintaining the concentration of air direction while further reducing structural interference and airflow resistance.

[0043] A mating hole 334 is installed through the surface of the fin 322. One end of the mating hole 334 is connected to the heat conduction plate 310. One end of the air outlet pipe 333 adjacent to the fin 322 extends into the corresponding mating hole 334.

[0044] In this embodiment, the air outlet pipe 333 guides the airflow into the docking hole 334 on the surface of the fin 322. The airflow can penetrate the fin 322 along the docking hole 334 and act on the area connected to the heat conduction plate 310, thereby achieving direct air cooling and scouring of the heat source at the bottom of the heat conduction plate 310, effectively improving the heat dissipation response speed and efficiency.

[0045] Working Principle: During printer operation, the drum core 200 in the toner cartridge 100 generates a large amount of heat due to friction and static electricity during continuous image transfer. This heat is first conducted to the heat-conducting plate 310 through the contact area between the drum core 200 and the heat-conducting plate 310. The heat-conducting plate 310 is arc-shaped and closely adheres to one side of the drum core 200, which can expand the heat-conducting contact area and quickly absorb the heat on the surface of the drum core 200. The heat-conducting plate 310 conducts the heat outward to multiple fins 322 fixedly connected to its outer side. The multiple fins 322 are equidistantly arranged and extend through the shell of the toner cartridge 100, forming a continuous heat dissipation path. Utilizing its large surface area, it exchanges heat with natural convection air, further improving heat dissipation efficiency. The surface of the drum 100 is provided with multiple ventilation holes 323 located on one side of the fins 322 to guide airflow, remove residual heat from the surface of the fins 322, and prevent local heat accumulation. At the same time, the fan 331 in the auxiliary component 330 can be started when the temperature of the drum core 200 is high. The airflow output by the fan 331 is guided to the area above the fins 322 through multiple air outlet pipes 333. With the help of the fixing cover 332, the airflow is concentrated and guided to the gap between the fins 322, effectively flushing away the heat between the fins 322. The air outlet pipes 333 extend into the docking holes 334 on the surface of the fins 322, so that the airflow can pass through the fins 322 and act directly on the connection surface of the heat conduction plate 310, further enhancing the cooling effect of the heat conduction core area.

[0046] It should be noted that the fans, temperature-sensitive color-changing panels, etc. mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the fans can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0047] 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.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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.
