Description

Technical Field

[0001] This utility model belongs to the field of refillable ink cartridge technology, and in particular relates to a refillable ink cartridge that is easy to add toner. Background Technology

[0002] Refillable ink cartridges are a type of consumable used in inkjet printers that can be refilled with ink. They extend the lifespan of the printer by adding ink, offering cost savings and environmental benefits. They are available in two types: with and without a printhead.

[0003] Existing refillable ink cartridges with easy toner refilling feature a tendency for the sealing plug on the outer wall to detach during use, leading to a decrease in the sealing performance of the sealing plug. Therefore, we propose a refillable ink cartridge with easy toner refilling. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a refillable ink cartridge that facilitates toner filling and enables stable installation of the sealing plug.

[0005] In view of this, the present invention provides a refillable ink cartridge that facilitates toner refilling, comprising a refillable ink cartridge body, a limiting block fixedly connected to one end of the refillable ink cartridge body, an installation spring fixedly connected to the end of the refillable ink cartridge body away from the limiting block, a toner refill seat installed at the top of the refillable ink cartridge body, a connection port provided on the inner wall of the toner refill seat, a sealing plug fitted into the inner wall of the connection port, a sealing ring provided at the connection between the sealing plug and the connection port, a handle fixedly connected to the top of the sealing plug, a pressure ring fixedly connected to the outer wall of the sealing plug, a rubber seat fixedly connected to the bottom of the sealing plug, and a vent seat installed at the top edge of the refillable ink cartridge body, with a vent opening on the inner wall of the vent seat.

[0006] Based on the above structure, the operator injects toner into the filling cartridge body through the connection port on the inner wall of the toner refill holder. Then, the operator fits the sealing plug into the connection port on the inner wall of the toner refill holder. By setting a sealing ring, the sealing performance of the sealing plug is improved. At the same time, by setting a pressure ring and a rubber seat, the sealing plug and the toner refill holder are stably engaged, preventing the sealing plug from falling off and causing a decrease in the sealing performance of the sealing plug.

[0007] Preferably, the mounting spring is V-shaped. In this embodiment, by setting the mounting spring in a V-shape, it is easy to install the ink cartridge body on the printer.

[0008] Preferably, the central axis of the toner filling seat coincides with the midpoint of the top of the filling cartridge body. In this embodiment, it is beneficial for the operator to evenly inject toner into the filling cartridge body through the connection port on the inner wall of the toner filling seat.

[0009] Preferably, the sealing plug is in the shape of an inverted frustum. In this embodiment, by setting the sealing plug in the shape of an inverted frustum, it is beneficial to increase the contact area between the sealing plug and the connection port and improve the sealing performance of the sealing plug.

[0010] Preferably, the handle has a "T" shaped cross-section. In this embodiment, by setting a handle with a "T" shaped cross-section, it is convenient for workers to remove the sealing plug through the handle.

[0011] Preferably, the rubber seat is in the shape of an inverted cone. In this embodiment, by setting the rubber seat in the shape of an inverted cone, it is easy for the operator to smoothly fit the sealing plug into the connection port on the inner wall of the powder filling seat.

[0012] Preferably, the pressure ring and the rubber seat are parallel. In this embodiment, by setting the pressure ring and the rubber seat, it is easy for the sealing plug to be stably engaged with the powder filling seat, and to avoid the sealing plug from falling off, which would lead to a decrease in the sealing performance of the sealing plug.

[0013] The beneficial effects of this utility model are:

[0014] This refillable ink cartridge features a sealing plug. Operators inject toner into the cartridge body through a connection port on the inner wall of the refill holder. Then, the sealing plug is fitted into the connection port on the inner wall of the refill holder. A sealing ring enhances the sealing performance of the plug. Furthermore, a pressure ring and rubber seat ensure a stable engagement between the sealing plug and the refill holder, preventing the plug from detaching and compromising its sealing performance.
