Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a novel ink cartridge suitable for multicolor printing. Background Technology

[0002] Currently, inkjet printers are typically supplied with ink by ink cartridges. Each ink cartridge usually has only one ink chamber, and each ink chamber can only be filled with one color.

[0003] If a multi-color printing scheme is used, multiple ink cartridges are required. For example... Figure 1 and 2 As shown, a four-color printing scheme requires four ink cartridges, which are connected to four printheads via four ink tubes. Due to the size limitations of the ink cartridges themselves, the distance between adjacent printheads is smaller than the distance between adjacent ink cartridges. Therefore, the inconsistent lengths of the four ink tubes cause the ink to enter the four printheads at different times, affecting the printing quality. If the longest ink tube is used to connect all four ink cartridges and printheads (keeping the four ink tubes of equal length), some ink tubes will have significant bends, resulting in different ink flow speeds, which will also affect the printing quality.

[0004] Therefore, there is an urgent need to invent a new type of ink cartridge with multiple ink tubes of the same length and the same degree of curvature connected to multiple printheads, wherein the multiple printheads can print different colors, thereby making the new ink cartridge suitable for multicolor printing.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of at least one of the above technical problems, this application provides a novel ink cartridge suitable for multicolor printing.

[0007] According to one aspect of this application, a novel ink cartridge suitable for multicolor printing is provided, comprising an ink cartridge body, characterized in that the ink cartridge body has n non-communicating ink cavities, wherein 4≤n≤8, the n ink cavities are parallel to each other, the ink outlets of the n ink cavities are on the same plane, and the center positions of the n ink cavities are respectively the n corner positions of an n-sided polygon.

[0008] In one implementation, the ink cartridge body includes a main housing and an ink cap connected to each other. The main housing has n non-communicating ink cavities. The main housing is fixedly connected to n pressure ports, which are respectively connected to the n ink cavities. The ink cavities are cylindrical.

[0009] In one implementation, n liquid level sensors are fixedly connected to the ink cap, and the probes of the n liquid level sensors are respectively located inside the n ink cavities.

[0010] In one implementation, the side of the ink chamber furthest from the pressure port is the ink outlet. The ink outlets of the n ink chambers are all fixedly connected to ink outlet switches. Each ink outlet switch includes an outlet, and the outlets of the n ink outlet switches are on the same plane.

[0011] This application has the following technical effects:

[0012] This application has four independent ink chambers in one ink cartridge. The ink cartridge is vertically mounted above the printhead via a bracket. The four independent ink chambers are connected to the four printheads via four ink tubes, which ensures that the four ink tubes are of the same length and have the same degree of curvature, thus solving the problem of printing effect affected by the different lengths and curvatures of each ink tube. In addition, the four independent ink chambers store different colors of printing ink, so the four printheads can print different colors, which is suitable for multi-color printing.

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0023] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0025] In one embodiment of this application, such as Figures 3-5 As shown, a novel ink cartridge suitable for multi-color printing is provided, including an ink cartridge body 1, which has n non-interconnected ink cavities, where 4≤n≤8. In this embodiment, n=4.

[0026] like Figure 3 and 4As shown, the ink cartridge body 1 is vertically mounted above the printhead 5 via a bracket. The ink cartridge body 1 includes a main housing 1a and an ink cap 1b connected together, and the main housing 1a and the ink cap 1b are fixedly connected by bolts. The main housing 1a has four non-communicating ink chambers, which are cylindrical in shape and arranged parallel and perpendicular to each other. The main housing 1a is fixedly connected to four pressure port pipes 2, which are respectively connected to the four ink chambers. The pressure port pipes 2 are distributed on the left and right sides of the main housing 1a and are located in the upper half of the main housing 1a. It should be noted that the pressure port pipes 2 are used to connect to a pressurized air source, making the air pressure inside the ink chamber different from atmospheric pressure, thereby squeezing the ink inside the ink chamber to the printhead 5. Furthermore, the ink cap 1b is fixedly connected to four liquid level sensors 3, the probes of which are respectively located inside the four ink chambers. The liquid level sensors 3 are used to detect the ink level.

[0027] The side of the ink chamber furthest from the pressure port 2 is the ink outlet, that is, the lower side of the ink chamber is the ink outlet. The ink outlets of the four ink chambers are on the same plane, and the center positions of the four ink chambers are the four corner positions of a regular quadrilateral.

[0028] The ink outlets of the four ink chambers are all fixedly connected to ink outlet switch 4. The ink outlet switch 4 includes an outlet 4a. The outlets 4a of the four ink outlet switch 4 are on the same plane. The ink outlet switch 4 is used to switch the ink out.

[0029] As can be seen from the above, the four ink outlets of the ink cartridge body 1 are respectively fixedly connected to four ink outlet switches 4, the outlets 4a of the four ink outlet switches 4 are on the same plane, and the outlets 4a of the four ink outlet switches 4 are respectively connected to four different color printheads 5 through four ink tubes.

[0030] When the four different colored nozzles are arranged in sequence, such as... Figure 5 As shown, when the distance between adjacent printheads 5 is a, the distance between ink cavities at adjacent corner positions is 2a, which makes the length of the four ink tubes consistent and the degree of curvature consistent.

[0031] It should be noted that the ink chamber structure of the ink cartridge can be determined based on the distribution of the printheads. Therefore, when multiple printheads are distributed in a circumferential direction, the ink chamber is set horizontally. This technical solution is also within the scope of protection of this application.

[0032] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application. Any person skilled in the art can make many possible variations and modifications to the technical solution of this application, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this application. Therefore, all equivalent changes made based on the shape, structure, and principle of this application without departing from the content of the technical solution of this application should be covered within the protection scope of this application.
