Description

Multicolor inkjet

The present invention relates to a printing ink cartridge, and more particularly to a multi-color printing ink cartridge suitable for use in a printing device.

With the advancement of technology, printers have evolved to be easy to operate, providing a wide range of color documents and images that can be quickly printed by offices, schools and individuals. The inkjet printers not only have finished products. With the advantages of bright luster and full color, it can be printed on a variety of different materials. The comprehensive cost and practicality of inkjet printers play an important role in the market today and are widely used by the public.

Inkjet printers are currently mixed in four colors to achieve full-color printing. The so-called four colors are: Cyan, Magenta, Yellow, and Black. Ink printers store and supply CMYK four-color inks, extending a variety of ink structure, roughly divided into two types, one of which is the design of two separate ink cartridges, respectively black ink and color ink, The color ink cartridge has three ink chambers to accommodate CMY three color inks; the other type is a four-color separation ink cartridge design, and the CMYK four-color inks are independently set in different ink cartridges. The printer has a 5 to 6 color ink cartridge design to reduce printing costs.

In general, ink cartridges are consumables, so after using the inkjet printer for a period of time, the ink cartridges must be replaced because the ink in the ink cartridges is exhausted. Therefore, the general inkjet printer is convenient. Replacing the ink cartridge, designed with a snap-on carrier to carry the ink cartridge, allowing the user to quickly replace the ink cartridge that has been exhausted by the ink, and for setting a plurality of ink cartridges for storing a plurality of color inks, the carrier has a plurality of carriers There are more slots, but the more the number of carriers is, the more the processing complexity will increase, and the size of the printer will increase. Not only will the manufacturing and design costs of the printer rise, but it will also be difficult to meet today's technological development. Focus on light, short, and easy to carry. In addition, it is known that the outer shape of each ink cartridge is similar, and if the user neglects the installation, it is easy to mistakenly install the ink cartridge on the ink cartridge carrier to be replaced, causing ink confusion and printing. Color accuracy is greatly reduced, which in turn affects print quality.

Therefore, how to develop a multi-color printing ink cartridge which can improve the above-mentioned conventional technology and can take into consideration the convenience of use and the saving of manufacturing cost is an urgent problem to be solved in the technical field of the present invention.

The main purpose of the present invention is to provide a multi-color printing ink cartridge suitable for a printing device, which solves the problem that since the printing device has to be provided with more than two ink cartridge carriers, the ink cartridge is easily replaced when the ink cartridge is replaced. Installed on the correct carrier, and ink confusing occurs, and on the other hand, by reducing the number of ink cartridge holders, the design and material cost of printing ink cartridges can be saved.

In order to achieve the above object, a broader aspect of the present invention provides a multi-color inkjet cartridge comprising: a body having an accommodating space therein, and a partition member disposed in the accommodating space to define four ink chambers. The accommodating space inside the body further comprises four ink supply channels respectively having a first end portion and a second end portion, wherein the first end portion is respectively connected with the corresponding ink chamber, wherein the four ink supply channels are respectively The first and fourth ink supply channels are correspondingly disposed, and the second end portion is a structure vertically extending vertically downward to communicate with the respective ink ejection slots, and the second and third ink supply channels are also correspondingly disposed, and The two end portions are tapered structures extending horizontally and horizontally to the respective ink ejection grooves, so that the second end portions are all in communication with the corresponding ink ejection slots, and the inks in the four ink chambers are guided to the corresponding ink jets. Slot for printing work.
