ActiveCN224476741UMechanical engineeringToner refill
This utility model belongs to the field of refillable ink cartridge technology, and particularly relates to a refillable ink cartridge that facilitates toner refilling. It includes a refillable ink cartridge body, with a limiting block fixedly connected to one end of the body. An installation spring is fixedly connected to the end of the body away from the limiting block. A toner refilling seat is installed at the top of the body. A connection port is provided on the inner wall of the refilling seat, and a sealing plug is fitted into the inner wall of the connection port. A sealing ring is provided at the connection between the sealing plug and the connection port. By using the sealing plug, the operator injects toner into the refillable ink cartridge body through the connection port on the inner wall of the refilling seat. Then, the operator fits the sealing plug into the connection port on the inner wall of the refilling seat. The sealing ring improves the sealing performance of the sealing plug. Simultaneously, the pressure ring and rubber seat facilitate a stable engagement between the sealing plug and the refilling seat, preventing the sealing plug from falling off and causing a decrease in its sealing performance.

A selenium drum powder box capable of assisting powder adding

This utility model relates to the field of toner cartridge technology, specifically a toner cartridge with auxiliary toner refilling capability. It includes a toner cartridge body for supplying toner, a feed pipe for feeding is connected through the upper part of the inner wall of the toner cartridge body, and a screw cap for sealing is threaded onto the upper part of the feed pipe. The toner cartridge body contains a feeding mechanism for auxiliary toner feeding and a dehumidification mechanism for dehumidifying the toner. The feeding mechanism includes a housing connected to the inner wall of the toner cartridge body for protecting bevel gears a and b. An auger for feeding is connected through a damping bearing to the upper part of the inner wall of the housing and is disposed inside the feed pipe. This toner cartridge with auxiliary toner refilling assists in refilling by inserting the toner bottle into the feed pipe and then continuously squeezing the arc-shaped toothed plate to drive the auger to rotate, preventing blockage during toner refilling. A desiccant absorbs moisture from the toner inside the toner cartridge body, preventing clumping.
