Description

Technical Field

[0001] This application relates to the field of equipment technology for electrical recording processes using charge patterns, and more specifically to a high-capacity toner cartridge. Background Technology

[0002] In imaging devices such as laser printers and copiers, the toner cartridge and waste toner container are core components ensuring continuous printing. The toner cartridge stores new toner and delivers it to the developing unit via a toner supply mechanism to form a visible image on the photosensitive medium. The waste toner container collects residual toner that failed to transfer to the paper during printing, preventing leakage and contamination of the device's internal components or impact on subsequent print quality. As users' demands for printing efficiency and battery life increase, the capacity of the toner cartridge has become a key indicator. However, current technologies often suffer from insufficient space utilization in the layout of the toner cartridge and waste toner container: to avoid interference, they are typically designed as separate units, with large gaps between them or a vertically stacked structure without space reuse. This results in a significant amount of unused internal space, making it difficult to increase the toner cartridge capacity. Simply increasing the volume of the toner cartridge to increase capacity would increase the overall size of the device, contradicting the trend towards miniaturization and portability in printers.

[0021] Reference Figure 1-4 As shown, an embodiment of this application is proposed. The increased capacity toner cartridge in this embodiment includes a toner cartridge body 10 and a waste toner cartridge 20. The toner cartridge body 10 is installed at the lower end of the waste toner cartridge 20. A gap is formed between the lower end of the waste toner cartridge 20 and the front side of the upper end of the toner cartridge body 10. This gap constitutes the laser channel 30. The left and right sides of the upper front side of the toner cartridge body 10 are respectively provided with capacity expansion chambers. The capacity expansion chamber includes a first receiving chamber 40 and a second receiving chamber 50. The first receiving chamber 40 is distributed directly below the waste toner cartridge 20. The second receiving chamber 50 is distributed in front of the front end of the waste toner cartridge 20, and the upper end of the second receiving chamber 50 extends to the top of the front end of the waste toner cartridge 20.

[0022] Referring to the attached drawings, the toner cartridge body 10 is provided with a toner stirring frame, a developing roller 11 and a toner dispensing blade 12, and the waste toner cartridge 20 is provided with a photosensitive drum 23, a charging roller 24 and a cleaning blade 25. The printer's laser emitter emits a laser beam, which passes through the laser channel 30 and irradiates the surface of the photosensitive drum to form an electrostatic latent image on the surface of the photosensitive drum.

[0023] In this application, both sides of the upper end of the toner cartridge body 10 are provided with expansion chambers. Since there is originally a gap between the toner cartridge body 10 and the waste toner cartridge 20 for the laser beam to pass through, the first receiving chamber 40 utilizes the idle space between the waste toner cartridge 20 and the toner cartridge body 10 to increase the capacity of the toner cartridge body 10; the second receiving chamber 50 extends to the front end and above the waste toner cartridge 20, further utilizing the longitudinal space in front of the waste toner cartridge 20, making full use of the idle space in front of the toner cartridge in the printer, and maximizing the capacity of the toner cartridge body 10.

[0024] In this embodiment, the first storage compartment 40 and the second storage compartment 50 are interconnected.

[0025] As the capacity of the toner container body 10 is increased, this embodiment also enlarges the cavity for holding waste toner on the waste toner container 20 to meet the capacity requirements of waste toner.

[0026] Furthermore, as a preferred embodiment, the waste powder bin 20 is provided with a clearance groove 21 at the lower front end, and a photosensitive drum is provided inside the waste powder bin 20, with the photosensitive drum distributed directly behind the clearance groove 21, and the clearance groove 21 forming the laser channel 30.

[0027] On the one hand, the clearance groove 21 is directly opened at the lower front side of the waste powder bin 20, serving as the physical carrier of the laser channel 30. Its dimensional accuracy, such as width, depth, and parallelism, can be strictly controlled through the injection molding process of the waste powder bin 20 to ensure imaging stability.

[0028] On the other hand, the clearance groove 21 directly utilizes the structural space of the waste toner hopper 20 to form the laser channel 30, eliminating the need to reserve an independent channel gap between the toner hopper body 10 and the waste toner hopper 20, thus avoiding space waste. This makes the layout of the waste toner hopper 20, the photosensitive drum, and the laser channel 30 more compact. The laser channel 30 does not occupy the space of the toner hopper body 10. At the same time, the space of the clearance groove 21 in the waste toner hopper 20 is used to set up the first receiving hopper 40 and the second receiving hopper 50 to maximize the capacity of the toner hopper body 10.

[0029] Preferably, the waste powder bin 20 has a handle 22 at the middle of its front end, and the front end of the second receiving bin 50 is flush with the front end of the handle 22.

[0030] This application extends the front end of the second storage compartment 50 to be flush with the front end of the handle 22, so that the second storage compartment 50 can make full use of the space occupied by the handle 22 of the waste toner compartment 20 inside the printer, maximize the capacity of the second storage compartment 50, and further improve the capacity of the toner compartment body 10.

[0031] Preferably, the front sidewall of the second receiving chamber 50 is on the same plane as the front sidewall of the toner cartridge body 10, and the front sidewall of the second receiving chamber 50 and the front sidewall of the toner cartridge body 10 gradually slope backward from top to bottom.

[0032] See attached document Figure 2 As shown, the front sidewall of the second receiving chamber 50 is on the same plane as the front sidewall of the toner container body 10, so that the toner in the second receiving chamber 50 can flow smoothly into the toner container body 10 and avoid dead corners. At the same time, the front sidewall of the second receiving chamber 50 and the front sidewall of the toner container body 10 gradually slope backward from top to bottom, which helps to guide the toner in the toner container body 10 to flow to the mixing rack and reduce toner clumping.

[0033] Based on the above, the toner cartridge body 10 described in this application includes a toner stirring rack 60, which is rotatably mounted on the toner cartridge body 10 and located directly above the center of the bottom wall of the toner cartridge body. In this embodiment, the bottom wall of the toner cartridge body 10 is arc-shaped, and the toner stirring rack 60 is located directly above the arc-shaped bottom wall.

[0034] In this embodiment, the two first receiving chambers 40 are provided with inclined surfaces 41 on the side that are close to each other, and the two inclined surfaces 41 gradually approach each other from back to front, so that the laser beam can pass smoothly through the laser channel 30 and irradiate the photosensitive drum, without increasing the length of the drum and without affecting the normal use of the drum.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
