Description

A toner cartridge that is easy to refill with toner Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically a toner cartridge that is easy to fill with toner. 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. It is a crucial imaging component in devices such as laser printers, copiers, and fax machines. Its main function is to adhere toner onto paper through processes such as laser exposure and electrostatic imaging, thereby completing the printing or copying work.

[0003] The existing patent announcement number CN220691259U discloses an easy-refill toner cartridge. Through the coordinated use of components such as a top-loading rod, toner refill bottle, telescopic rod, return spring, sealing plug, and screw feeder, the easy-refill toner cartridge effectively seals the toner hopper and toner refill bottle during use. During toner refilling, the elastic extension and retraction of the telescopic rod and return spring facilitate toner addition, while the rotation of the screw feeder further assists in toner addition. This effectively prevents clogging due to low toner flow during refilling, thus significantly improving the efficiency and ease of use of the easy-refill toner cartridge.

[0004] However, during use, the device requires manual rotation of the top handle. When the torque is insufficient, the operator needs to use both hands to rotate it, which can easily lead to instability of the toner refill bottle. The bottle may shake during rotation, and in severe cases, it may tip over, spilling toner and causing waste.

[0005] Based on this, a toner cartridge that is easy to fill with toner is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention
