Description

 Universal printer toner cartridge

The present invention relates to the field of printer technology, and more particularly to a toner cartridge that is commonly used in various types of printers for supplying toner to a printer. The present application claims priority to Chinese Patent Application No. 201120343070.9, entitled "A Universal Printer Toner Cartridge", filed on September 14, 2011, the entire contents of which is incorporated herein by reference. .

Usually, different types of printers can only use the corresponding type of toner cartridge due to the difference in structure. However, when the market demand for certain types of toner cartridges rises, manufacturers may have a capacity that cannot meet market demand, and different types of toner cartridges cannot be interchanged, resulting in an imbalance between supply and demand. HP The 1500/2550 is similar in structure to the HP 2500 but cannot be completely down. The recycling box is not directly proportional to the product sales. For example, the HP 1500/2550 recycling box is more than the order, HP 2500 recycling boxes are less than orders. This results in an order that does not have a recycling box, and that has a recycling box and a small number of recycling boxes.

The technical problem to be solved by the present invention is to provide a toner cartridge which is commonly used for various types of printers, in view of the problem that the existing toner cartridges are not compatible and difficult to meet market demands.

The technical solution adopted by the present invention to solve the technical problem thereof is to construct a general-purpose printer toner cartridge including a toner cartridge case and a developing roller mounted on the toner cartridge case, the toner cartridge case Both ends of the body are respectively provided with a gear cover and a developing roller conductive end baffle, and the gear cover is straight, and the developing roller conductive end baffle is straight.

According to the universal printer toner cartridge of the present invention, the gear cover is made by removing the bump by a cover having a bump.

According to the universal printer toner cartridge of the present invention, the developing roller conductive end shield is made by removing the projection by a baffle having a bump.

According to the universal printer toner cartridge of the present invention, the side surface of the gear cover is a curved surface.

According to the universal printer toner cartridge of the present invention, the side surface of the developing roller conductive end stop is a curved surface.

The universal printer toner cartridge embodying the present invention has the following advantageous effects: the present invention provides a toner cartridge which is commonly used in various types of printers, and the gear cover and the developing roller conductive end stop are straight, without There are bumps to avoid the situation that the shape and position of the bumps are not adapted, so that it can not be dropped, so that it can be successfully dropped in various types of printers, meeting the market demand.

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention lists two specific embodiments for illustration.

Referring to Figure 1-3, the toner cartridge is an existing toner cartridge model HP2500. 1 is a perspective view of the toner cartridge, FIG. 2 is a side view of the gear cover side of the toner cartridge, and FIG. 3 is a side view of the conductive roller baffle side of the developing roller of the toner cartridge. As shown in the figure, the toner cartridge includes a toner cartridge general structure such as a toner cartridge casing 1 and a developing roller 2 mounted on the toner cartridge casing 1. The toner cartridge case 1 is provided with toner for the printer, and the two ends of the developing roller 2 are mounted on the two end plates of the toner cartridge case 1, which are respectively the gear cover 3 and the developing roller conductive end baffle 4.

As shown in Figure 1-3, the gear cover 3 of this model has a bump 5 on it, and the shape and position of the bump 5 are not applicable to the printer model HP1500/2550, which will hinder the model. A printer model HP1500/2550 is fitted to the HP2500 toner cartridge. On the other hand, in FIG. 3, the developing roller conductive end baffle 4 of the toner cartridge is straight, without bumps, and does not hinder the machine.

Please refer to FIG. 4, which is a perspective view of a first embodiment of a universal printer toner cartridge in accordance with the present invention. After removing the bumps 5 on the gear cover 3 of the HP2500 toner cartridge shown in FIG. 1-3, the utility model provides a universal printer toner cartridge provided with the gear cover 3 straight. And the developing roller conductive end baffle 4 is straight, which facilitates the drop in the printer of the model HP1500/2550. The term "straight" as used in the present invention refers to a bump structure that does not have a significant effect on the drop, and does not exclude a raised structure having other dimensions or positions that do not affect the drop. As shown in the figure, the side of the gear cover 3 of the universal printer toner cartridge is a curved surface, and the side surface of the developing roller conductive end shield 4 is also curved, thereby being adapted to the corresponding structure in the printer, which is convenient. Down the plane.
