Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and in particular to a waste toner storage structure. Background Technology

[0002] In modern laser printing technology, the toner cartridge, as a core consumable component, directly impacts print quality and user experience through its performance and structural design. The waste toner compartment within the cartridge plays a crucial role in collecting waste toner generated during the printing process. Currently, common waste toner compartment structures primarily consist of a base 10 and an outer cover 50, which work together to form a waste toner storage cavity 100. This structure can, to a certain extent, meet basic waste toner collection needs.

[0003] However, with the continuous increase in printing volume and the growing demand for long-term use of toner cartridges, the limitations of existing waste toner compartment structures are becoming increasingly apparent. One key issue is the significant difficulty in expanding the space of the entire waste toner storage chamber. Due to the constraints of its own structural design, increasing the space of the waste toner storage chamber often requires changing the shape of the outer cover. However, when the shape of the outer cover changes, the shape and volume of the entire waste toner compartment also change accordingly.

[0004] It is important to note that the toner cartridge, as a component that needs to be installed inside the printer, must have a shape and size that precisely match the printer's internal structure. If the shape of the waste toner cartridge changes, causing a change in the overall shape of the toner cartridge, it is highly likely that the toner cartridge will not be able to be installed properly inside the printer, or even if it can be installed, stable operation during printing cannot be guaranteed, thus affecting print quality and the normal operation of the printer.

[0005] Therefore, optimizing the structural design of the waste toner cartridge compartment and increasing the capacity of the waste toner storage cavity to meet user needs has become an urgent technical problem to be solved. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a waste powder silo structure equipped with an incremental storage cavity.

[0007] A waste powder hopper structure designed for this purpose includes a waste powder hopper base and a shaped sealing element. The waste powder hopper base and the shaped sealing element are sealed together to form a waste powder storage cavity. The waste powder storage cavity has a powder inlet on the side near the drum core. The shaped sealing element is connected to a cleaning scraper on the side near the drum core. The cleaning scraper is used to fit against the drum core. The shaped sealing element has an incremental storage cavity extending away from the waste powder hopper base. The incremental storage cavity is interconnected with the waste powder storage cavity.

[0008] Preferably, the irregularly shaped sealing element is disposed below the waste powder hopper base, and the incremental storage cavity protrudes outward.

[0009] Preferably, the incremental storage cavity includes an outwardly protruding first incremental storage space, which is in communication with the waste powder storage cavity.

[0010] Preferably, the incremental storage cavity includes an outwardly protruding second incremental storage space, which is in communication with the waste powder storage cavity.

[0011] Preferably, the powder inlet is located on the front side of the waste powder storage chamber, the drum core is located on the lower front side of the powder inlet, and the incremental storage chamber is connected to the rear side of the cleaning scraper.

[0012] Compared with existing technologies, this utility model's waste toner cartridge structure, through innovative design, effectively overcomes the shortcomings of existing technologies and possesses significant beneficial effects. Firstly, the waste toner cartridge base and a uniquely shaped sealing element form a waste toner storage cavity. Compared to the traditional waste toner cartridge cover structure, the uniquely shaped sealing element, through its unique structural form, allows for the creation of an incremental storage cavity extending away from the waste toner cartridge base without altering the overall dimensions of the drum unit. This incremental storage cavity is interconnected with the waste toner storage cavity, enabling flexible increases in the volume of the waste toner storage cavity. This effectively meets the increased demand for waste toner storage capacity as printing volume increases, extending the drum unit's lifespan. Secondly, the design of the incremental storage cavity extending away from the waste toner cartridge base avoids the problem of the drum unit being unable to adapt to the printer's internal structure due to changes in the overall shape and volume of the waste toner cartridge. While ensuring the compatibility of the drum unit and printer installation, it enhances the waste toner cartridge storage capacity, ensuring the drum unit can be stably installed inside the printer and operate normally, guaranteeing stable print quality and reliable printer operation.

[0024] See Figures 1-2 A waste toner hopper structure includes a waste toner hopper base 10 and a shaped sealing element 20. The waste toner hopper base 10 and the shaped sealing element 20 are sealed together to form a waste toner storage cavity 100. The waste toner storage cavity 100 has a toner inlet 110 on the side near the drum core 40. A cleaning scraper 30 is connected to the side of the shaped sealing element 20 near the drum core 40, and the cleaning scraper 30 is used to fit against the drum core 40. The shaped sealing element 20 has an incremental storage cavity 200 extending away from the waste toner hopper base 10, and the incremental storage cavity 200 is interconnected with the waste toner storage cavity 100. Compared with the traditional waste toner hopper outer cover structure, the shaped sealing element, through its unique structural shape, can form an incremental storage cavity extending away from the waste toner hopper base without changing the overall fit size of the drum. The incremental storage cavity is interconnected with the waste toner storage cavity, allowing the volume of the waste toner storage cavity to be flexibly increased. This effectively meets the demand for increased waste toner storage capacity when printing volume increases, and extends the service life of the drum unit.

[0025] In this invention, the irregularly shaped sealing element 20 is connected to the waste powder hopper base 10 by welding, bonding, or fasteners. The irregular shape of the sealing element 20 indicates that it is not a straight plate.

[0026] See Figure 1 The irregularly shaped sealing element 20 is located below the waste toner cartridge base 10, and the incremental storage cavity 200 protrudes outward. This outward protrusion design avoids the problem of the toner cartridge being unable to adapt to the printer's internal structure due to changes in the overall shape and volume of the waste toner cartridge. While ensuring the compatibility of the toner cartridge with the printer, it improves the waste toner cartridge's storage capacity, ensuring the toner cartridge can be stably installed inside the printer and work normally, thus guaranteeing the stability of print quality and the reliability of printer operation.

[0027] See Figure 1 The incremental storage cavity 200 includes an outwardly protruding first incremental storage space 210, which is in communication with the waste powder storage cavity 100.

[0028] See Figure 1 The incremental storage cavity 200 includes an outwardly protruding second incremental storage space 220, which is in communication with the waste powder storage cavity 100.

[0029] In this invention, the powder inlet 110 is located on the front side of the waste powder storage cavity 100, the drum core 40 is located on the lower front side of the powder inlet 110, and the incremental storage cavity 200 is connected to the rear side of the cleaning scraper 30.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
