Description

Technical Field

[0001] This utility model relates to the field of printer consumables technology, specifically to a leak-proof toner cartridge. Background Technology

[0002] In modern office and printing fields, electronic imaging devices such as laser printers, copiers, and fax machines are widely used. Among these devices, the toner cartridge, as a key component, undertakes the important task of developing electrostatic latent images. Its performance directly affects the quality of printing. The toner cartridge, as the core component for storing and supplying toner, plays an indispensable role in the entire imaging process.

[0003] During the use of a printer, the toner cartridge is one of the most important consumables. Its performance directly affects the print quality and the lifespan of the printer. As an indispensable core consumable for printers, the performance of the toner cartridge not only directly determines the clarity, color saturation and other quality indicators of the printed product, but is also closely related to the long-term stable operation and lifespan of the printer.

[0004] However, existing toner cartridges often experience toner leakage, causing many problems for users. Over time, toner may accumulate inside, making it difficult to clean the inside of the device. To solve the toner leakage problem, some toner cartridges have a single sealing gasket at the toner outlet. However, as the usage time increases, the sealing gasket is prone to wear, resulting in a decrease in sealing performance and toner leakage still occurring. Utility Model Content
