Description

Technical Field

[0001] This utility model belongs to the field of ink cartridge technology, specifically relating to a high-capacity ink cartridge structure. Background Technology

[0002] Ink cartridges are an essential component of inkjet printers, primarily used for ink supply. Current ink cartridges mainly consist of a cartridge body and a chip-embedded printhead located at the bottom of the body. While these can meet general usage needs, their ink reservoirs are relatively small, resulting in limited ink capacity and affecting print volume. Furthermore, during ink replenishment and printing, the ink inside the cartridge tends to shift when the cartridge is moved horizontally, affecting the uniformity of inkjet printing. Additionally, as the ink level drops, the internal pressure decreases, further impacting print smoothness. These factors, to some extent, affect the stability and effectiveness of the print, making it difficult to meet market demands. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] See Figures 1 to 5 As shown, a high-capacity ink cartridge structure includes a cartridge body 1 and an inkjet head 2 with a chip disposed at the bottom of the cartridge body. The bottom wall of the cartridge body is provided with several plug-in ports 3 that are plugged into and connected to the connection terminals on the chip. In this embodiment, the cartridge body, inkjet head, chip and plug-in ports are all conventional structures of the prior art, and are simply applied, so they are not described in detail. There are four plug-in ports.

[0028] In this embodiment, a cavity 4 is provided on the top surface of the box body, and a through hole 5 communicating with the inner cavity of the box body is fixed on the bottom wall of the cavity. The depth of the cavity can be processed and set as needed, mainly for installing a constant pressure valve body. A constant pressure valve body 6 is provided in the cavity, and an air guide pipe 7 is fixed to one end of the constant pressure valve body. The end of the air guide pipe is inserted into the through hole. An air inlet pipe 8 is provided on the side wall of the constant pressure valve body. The constant pressure valve body is a conventional structure in the prior art, and it is simply applied. It is mainly used to control the pressure inside the box body to keep it constant, so that the ink inside the box body can be sprayed effectively and smoothly. When in use, the ink inside the box body descends, and external gas enters the box body through the air inlet pipe, the constant pressure valve body and the air guide pipe to keep the pressure inside the box body constant.

[0029] In this embodiment, a plurality of parallel partitions 9 are provided on the inner wall of the cartridge, and a gap 10 is provided between the bottom edge of the partition and the bottom wall of the cartridge. The partitions can separate the ink inside the cartridge, and the gaps can allow the ink to flow. The separation can prevent the ink inside the cartridge from shaking when the cartridge moves, thus improving the inkjet efficiency.

[0030] In this embodiment, a C-shaped clearance groove 11 is provided on the side wall of the cavity, and the through hole is located on the bottom wall of the C-shaped clearance groove. This structure facilitates the installation and positioning of the air guide tube.

[0031] In this embodiment, a plurality of protruding posts 12 are integrally formed on the bottom wall of the cavity; and a pressure cap 13 is provided on the upper part of the cavity, and a hollow retaining post 14 that cooperates with the protruding posts is provided on the bottom surface of the pressure cap; during assembly, the pressure cap is placed inside the cavity, and the protruding posts are positioned by engaging with the holes of the hollow retaining post. This structure improves the ease of installation of the pressure cap, protects the internal constant pressure valve body, and allows external air to enter through the gap between the pressure cap and the cavity, improving operational stability and effectiveness.

[0032] In this embodiment, the outer wall of the cartridge body is provided with a guide groove 15 that engages with the ink cartridge holder. This improves the stability and reliability of the installation with the ink cartridge holder, preventing shaking or displacement. At the same time, to facilitate the disassembly and assembly of the cartridge body, the upper part of the symmetrical side walls of the cartridge body is fixed with anti-slip raised textures 16 for finger contact during ink cartridge disassembly and assembly.

[0033] This utility model has positive effects: The structure of this utility model is reasonable. It has a cavity on the top surface of the cartridge and a through hole on the bottom wall of the cavity. With the constant pressure valve and air guide tube, air can be supplied to the cartridge when the ink in the cartridge is falling, so that the pressure inside the cartridge is constant and the ink storage capacity of the cartridge can be increased. This is beneficial to the uniformity, smoothness and effectiveness of ink spraying. At the same time, it is provided with a plug-in port, which is conducive to quick and effective connection with the inkjet head and stable and reliable use.

[0034] Furthermore, in this embodiment, there are several parallel partitions on its inner wall, which can prevent the ink inside the cartridge from shaking, thus improving the effectiveness and reliability of the ink cartridge and making it highly applicable.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
