Description

  The present invention relates to a technical field of ink cartridges that can be used in a redundant manner. In particular, the present invention refers to an ink cartridge structure that can be opened and closed quickly and that is convenient for exchanging ink bags.

  The capacity of ink cartridges employed in commercial ink jet printers is usually 400 to 600 ml, and currently, in order to avoid occupying excessive space when the ink cartridge is attached to the printer, such an ink cartridge configuration is used. Many of them are elongated rectangular parallelepipeds, and the length-width ratio can reach 6 times or more.

  Inside such an ink cartridge, a variable-form ink bag is accommodated, and the ink bag undertakes a continuous large amount of ink delivery. Since the ink bag has a large amount of ink, if the ink bag is not fixed in the ink cartridge, the ink cartridge case will be compressed by shaking during the transportation process or excessive ink concentrating on the ink bag local area. Easy to burst.

  Therefore, at present, the local surface of the ink bag in such an ink cartridge is bonded to the inner wall to be a primary use ink cartridge, and when the ink is used up, the ink cartridge must be replaced. This increases the cost of the user purchasing duplicate ink cartridges, and the waste ink cartridge case can also create waste of resources and environmental pollution.

  For this reason, the present inventor has designed a replaceable ink bag and has come up with an alternative to an ink bag that is adhesively fixed to an ink cartridge. At the same time, it is necessary to newly design the structure of the ink cartridge so that the ink cartridge can be opened and closed in a duplicated manner so that the ink bag can be replaced.

  Traditional high-capacity ink cartridges are primarily primary-use products, and the ink cartridge cover and cartridge body need not be reopened after being closed. As a result, most of the structure is a unidirectional locking system. Once the cover is closed with the cartridge body, if one tries to open it forcibly, one of the parts will be damaged. It is necessary to open by adopting a specific method with the aid of tools. For example, a driver is inserted into a specific groove or hole of the ink cartridge, and a force is applied to rotate the screw cartridge to open the cover. Alternatively, with a screw driver, a screw for fixing between the cover and the cartridge body is turned and loosened.

  For this reason, the procedure at the time of replacing the ink bag is cumbersome. For example, the specific tool must be searched first, which is inconvenient for the user. Therefore, the present inventor is based on many years of experience, The ink cartridge opening and closing structure was designed at the end of continuous improvement.

  The main object of the present invention is to provide a kind of mechanism that can open and close an ink cartridge without the need for tool assistance, and when the design of the present invention is operated, the ink cartridge is merely opened or attached in a specific manner. The ink cartridge cover can be attached to the cartridge body in a specific operation flow, or the cover can be quickly separated from the cartridge body, and thus the ink cartridge can be opened and closed. This is convenient when changing bags.

  In order to achieve the above-described object, the ink cartridge of the present invention includes at least a cartridge body and a cover, and both are combined to form a container for accommodating a replaceable ink bag. At least one hook is provided on each of two opposite sides of the joint surface of the cover with the cartridge body, and at least one locking unit is provided on each of the two long side walls facing the cartridge body. The locking unit is composed of a groove and an elastic locking part, and when combined, the hook of the cover is inserted into the groove of the cartridge body, and the elastic locking part suppresses the edge of the hook, When the cover is separated and the cover is separated from the cartridge body, the cover is moved sideways, and the hook is separated from the locking by the elastic locking portion along the track of the groove. The cover can be lifted upward to be separated from the cartridge body.

  When the design of the present invention is operated, when the cover is attached to the cartridge body, the cover can be engaged with and fixed to the cartridge body simply by pressing the cover against the cartridge body from above at a predetermined angle. Speedy and convenient.

  If you want to replace the ink bag, move the cover a short distance sideways at the top of the cartridge body, and then raise the cover from the bottom to the top. This is more convenient for replacing the ink bag of the ink cartridge.

It is a three-dimensional view of the present invention. It is an exploded view at the time of actual use of the present invention.
