Description

Technical Field

[0001] This invention relates to an ink cartridge assembly and its processing technology. Background Technology

[0002] Everyday inkjet printers use ink cartridges for printing, and consumers discard them after use. These discarded cartridges are then recycled by manufacturers, refilled with ink, and made into recycled ink cartridges for reuse, achieving environmental protection and cost savings.

[0003] However, the discarded ink cartridges are made of black plastic all around, so manufacturers and sellers cannot see the amount of ink in the cartridges during production and use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of the prior art in which the ink content inside the ink cartridge assembly cannot be seen, and to provide an ink cartridge assembly and its processing technology.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An ink cartridge assembly includes an ink cartridge and a printhead, the ink cartridge and the printhead being integrally molded. The ink cartridge includes a foam chamber inside, and the ink outlet at the bottom of the foam chamber is connected to the ink inlet of the printhead. The printhead includes a chip.

[0007] The outer wall of the ink cartridge is transparent;

[0008] The ink cartridge also includes an ink chamber, which is arranged adjacent to the sponge chamber inside the ink cartridge, and a connecting hole is provided on the partition plate between the ink chamber and the sponge chamber;

[0009] The printhead includes the sidewall where the chip is located and the cell where the ink inlet is located.

[0010] In this application, the outer wall of the ink cartridge is made transparent, and the ink chamber and sponge chamber are connected. This solves the problem of not being able to see the ink level inside the cartridge in previous technologies. It also allows consumers to easily refill the cartridge based on the ink level, improving the efficiency of ink refilling for subsequent use. Furthermore, the adjacent arrangement of the sponge chamber and ink chamber, connected by a connecting hole, ensures normal ink flow from the ink outlet. The sponge inside the sponge chamber also ensures uniform ink flow from the outlet. Moreover, there is no need to discard empty ink cartridges; the transparent cartridge of this application allows for refilling with new ink, enabling repeated use. This is of great significance for the environmental protection and conservation of ink cartridge components.

[0011] Furthermore, placing a chip on the ink cartridge assembly facilitates its connection with the printer carriage probes, ensuring accurate positioning and identification between the ink cartridge assembly and the reading device. This also lays a solid foundation for subsequent inkjet printing operations. Moreover, the printhead structure in this application not only enhances the aesthetics of the ink cartridge assembly but also ensures the integrity of the chip on the side, resulting in a higher printhead yield. This avoids damaging the internal structure of the printhead and prevents issues such as circuit board damage or broken circuits on the chip. Additionally, this structural design of the ink cartridge assembly improves the ease of connection between the two components while reducing the need for high processing precision.

[0012] Preferably, the connecting hole is disposed on the spacer plate and on the side near the ink outlet of the ink cartridge.

[0013] In this application, this structural form not only makes it convenient for the ink in the ink chamber to be completely used up, but also increases the distance between the ink in the ink chamber and the ink outlet, preventing the ink from flowing too fast and overflowing.

[0014] Preferably, the ink cartridge further includes an ink cartridge cover, which is disposed on the side of the ink cartridge away from the ink outlet.

[0015] In this application, this structural form is adopted to avoid problems such as ink overflow and exposure in each chamber of the ink cartridge, thus ensuring the integrity of the ink inside the ink cartridge and the overall cleanliness of the ink cartridge.

[0016] Preferably, the ink cartridge cover is provided with an ink filling hole, which is located above the ink chamber and communicates with the ink chamber.

[0017] In this application, this structural form is adopted, which makes it convenient for staff to add ink into the ink cartridge when the ink cartridge cover is on the ink cartridge, without having to open the ink cartridge cover separately.

[0018] Preferably, an air inlet is provided on the ink cartridge cover, the air inlet being located above the sponge chamber and communicating with the sponge chamber.

[0019] In this application, this structural form is adopted to facilitate maintaining the air pressure balance inside the sponge chamber.

[0020] Preferably, the ink cartridge assembly further includes a gasket that is fitted over the ink inlet of the printhead and disposed between the printhead and the ink cartridge.

[0021] In this application, this structural form can effectively avoid problems such as ink overflow and exposure from the ink outlet to the ink inlet of the printhead, enhance the sealing between the printhead and the ink cartridge, and also avoid problems such as ink waste and environmental pollution.

[0022] Preferably, a first connecting portion is provided on the side of the ink cartridge near the printhead, and a second connecting portion is provided on the side of the printhead near the ink cartridge and corresponding to the first connecting portion, wherein the first connecting portion and the second connecting portion are adapted to each other.

[0023] In this application, this structural form, compared with the previous method of using glue, adopts a connection method in which the first connecting part and the second connecting part are adapted to each other, which can make the connection between the ink cartridge and the print head more secure, avoiding the problems of weak glue bonding and easy detachment of ink cartridges in the past.

[0024] Preferably, at least a portion of the chip covers the sidewall of the ink cartridge.

[0025] In this application, this structural form is adopted, in which at least part of the chip covers the side wall of the ink cartridge, which can enhance the positioning effect of the new ink cartridge on the print head and ensure the accuracy of the ink cartridge placement on the print head.

[0026] Preferably, in the height direction, at least a portion of the chip protrudes beyond the highest horizontal plane where the ink inlet is located.

[0027] In this application, this structural form makes the processing of the printhead and ink cartridge assembly more convenient, and the positioning chip on the side of the printhead is retained, resulting in higher printhead integrity and yield. This avoids damage to the internal structure of the printhead and also avoids problems such as damage to the circuit board on the chip and broken circuits.

[0028] Preferably, the printhead includes a sidewall where the chip is located and a sidewall opposite to it. The printhead also includes a cell where the ink inlet is located and a cell corresponding to the ink chamber of the ink cartridge.

[0029] In this application, this structural form enhances the aesthetics of the ink cartridge assembly.

[0030] Preferably, the printhead further includes a nozzle disposed on the bottom surface of the printhead on the side away from the ink cartridge, for spraying ink flowing in from the ink inlet.

[0031] In this application, this structural form is adopted, with the printhead and ink cartridge respectively positioned on two opposite sides of the printhead, facilitating ink reception by the printhead and maintaining the normal operation of the ink cartridge assembly. A manufacturing process for an ink cartridge assembly, the process comprising the following steps:

[0032] S11. Preliminary processing of the partition plates between the various chambers inside the ink cartridge;

[0033] S12. Machining the plane where the ink outlet is located inside the ink cartridge;

[0034] S13. Cut the adjacent sidewall of the sidewall where the chip is located on the ink cartridge and its opposite sidewall.

[0035] S14. Cut off the remaining cells of the printhead, and only save the cell where the ink inlet is located;

[0036] S15. Install the ink cartridge with a transparent outer wall onto the print head.

[0037] Preferably, before step S11, the following step is also included: after the ink cartridge cover is opened, the plane between the ink cartridge and the ink cartridge cover is milled flat.

[0038] The positive and progressive effects of this invention are as follows:

[0039] 1. By making the outer wall of the ink cartridge transparent and adding a connecting ink chamber and sponge chamber, the previous technology solved the problem of not being able to see the ink level inside the cartridge. This also allows consumers to easily refill the cartridge based on the ink level, improving the efficiency of ink refilling for subsequent use. Furthermore, the adjacent placement of the sponge chamber and ink chamber, connected by a connecting hole, ensures normal ink flow from the ink outlet. The sponge inside the sponge chamber also ensures uniform ink flow from the outlet.

[0040] 2. There is no need to discard empty ink cartridge components. The transparent ink cartridge in this application can be filled with new ink and reused, which is of great significance for the environmental protection and conservation of ink cartridge components.

[0041] 3. The chip on the ink cartridge assembly facilitates its connection with the printer carriage probes, ensuring accurate positioning and identification between the ink cartridge assembly and the reading device. This also lays a solid foundation for subsequent inkjet printing operations. Furthermore, the printhead structure in this application not only enhances the aesthetics of the ink cartridge assembly but also ensures the integrity of the chip on the side, resulting in a higher printhead yield. This avoids damaging the internal structure of the printhead and prevents issues such as circuit board damage or broken circuits on the chip. Additionally, this structural design of the ink cartridge assembly improves the ease of connection between the two components while reducing the need for high processing precision.

[0081] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0082]

Example 1

[0083] like Figures 1-15 As shown, an ink cartridge assembly 200 is disclosed.

[0084] like Figures 1-7 As shown, the ink cartridge assembly 200 includes an ink cartridge 100 and a printhead 21. The ink cartridge 100 and the printhead 21 are configured as an integral structure. The ink cartridge 100 covers the printhead. The interior of the ink cartridge 100 includes a sponge chamber 11 and an ink chamber 12. The ink outlet 111 at the bottom of the sponge chamber 11 inside the ink cartridge 100 is connected to the ink inlet 211 of the printhead to ensure normal ink flow.

[0085] The ink chamber 12 and the sponge chamber 11 are arranged adjacently inside the ink cartridge 100 and separated by a partition plate 13. At the same time, a connecting hole 131 is provided on the partition plate 13 between the ink chamber 12 and the sponge chamber 11. The purpose of providing the connecting hole 131 is to allow the sponge in the sponge chamber 11 to absorb the ink in the ink chamber 12 through the connecting hole 131, ensuring that the ink is normally discharged from the ink outlet 111 below the sponge chamber 11. At the same time, the presence of a sponge in the sponge chamber 11 also ensures the uniformity of the ink flow from the ink outlet 111.

[0086] Specifically, the outer wall of ink cartridge 100 is transparent.

[0087] This structural design, with its transparent outer wall and interconnected ink chamber 12 and sponge chamber 11, solves the problem of not being able to see the ink level inside the cartridge 100 in previous technologies. It also allows consumers to easily refill the cartridge based on its ink level, improving the efficiency of ink refilling for subsequent use. Furthermore, it eliminates the need to discard empty cartridge components 200; the transparent cartridge 100 allows for refilling with new ink, enabling repeated use and representing a significant environmental and economical improvement for the cartridge component 200.

[0088] At the same time, such as Figures 3-5 The printhead 21 includes the side wall where the chip 212 is located and the cell 214 where the ink inlet 211 is located.

[0089] The structure of the ink cartridge 100 includes all the chambers inside the ink cartridge 100 and the adjacent side wall of the side wall where the chip 212 is located when the ink cartridge 100 is connected to the print head 21, as well as its opposite side wall. That is to say, after the ink cartridge 100 and the print head 21 are fully installed, the ink inlet 211 of the print head 21 is only compatible with the ink outlet 111 below the ink cartridge 100, and the side wall where the chip 212 is located is compatible with the two side walls of the ink cartridge 100. The two side walls of the ink cartridge 100 can be just snapped onto the print head 21, which enhances the reliability of the connection between the ink cartridge 100 and the print head 21.

[0090] In this embodiment, this structural form not only enhances the aesthetics of the ink cartridge assembly 200, but also ensures the integrity of the chip on the side chip 212, resulting in a higher yield of the printhead 21. This avoids damaging the internal structure of the printhead 21 and prevents problems such as damage to the circuit board or broken circuits on the chip 212. At the same time, setting the ink cartridge assembly 200 in this structural form improves the convenience of connection between the two while not requiring high processing precision.

[0091] Preferably, such as Figure 8 As shown, the connecting hole 131 is located on the partition plate 13 and near the ink outlet 111 of the ink cartridge 100. This structure not only allows the ink in the ink chamber 12 to be completely used up, but also increases the distance between the ink in the ink chamber 12 and the ink outlet 111, preventing the ink from overflowing due to excessive flow. If the connecting hole 131 were located on the partition plate 13, the inlet would be higher, resulting in greater pressure in the sponge chamber 11, creating a liquid level difference, and making the print head 21 prone to ink leakage.

[0092] like Figures 9-10 As shown, the ink cartridge 100 also includes an ink cartridge cover 14, which is placed on the side of the ink cartridge 100 away from the ink outlet 111. At the same time, there is a baffle 143 on the ink cartridge cover, which is adapted to match the partition 13 between the various chambers inside the ink cartridge. This can effectively prevent ink from overflowing or being exposed in the various chambers inside the ink cartridge 100, ensuring the integrity of the ink inside the ink cartridge 100 and the overall cleanliness of the ink cartridge 100.

[0093] Meanwhile, the ink cartridge cover 14 is provided with an ink filling hole 141 and an air inlet 142.

[0094] The ink filling hole 141 is located above and connected to the ink chamber 12. With this structure, when the ink cartridge cover 14 is on the ink cartridge 100, it is convenient for the staff to add ink into the ink cartridge 100 without having to open the ink cartridge cover 14.

[0095] The air inlet 142 is located above the sponge chamber 11 and is connected to the sponge chamber 11. This structure helps to maintain the air pressure balance inside the sponge chamber.

[0096] like Figure 3 and Figure 11 The diagram shown is a structural schematic of the printhead 21 in the color ink cartridge assembly 200.

[0097] The ink cartridge assembly 200 also includes a gasket 22, which is fitted onto the ink inlet 211 of the printhead 21 and positioned between the printhead 21 and the ink cartridge 100. In this embodiment, the function of the gasket 22 is to effectively prevent ink from overflowing or leaking from the ink outlet 111 to the ink inlet 211 of the printhead 21, enhance the seal between the printhead 21 and the ink cartridge 100, and also avoid ink waste and environmental pollution.

[0098] When connecting the ink cartridge 100 and the print head 21, the gasket 22 is glued to the upper and lower sides of the ink cartridge 100 and the print head 21 to enhance the stability of the connection.

[0099] In a preferred embodiment, the ink inlet 211 is also provided with a mesh for filtering ink.

[0100] Preferably, the side of the printhead 21 closest to the ink inlet 211 is arranged in a stepped shape.

[0101] The printhead 21 includes a chip 212, which is disposed on the side wall of the printhead 21, with at least a portion of the chip 212 covering the side wall of the ink cartridge 100. This structural design facilitates the connection between the chip 212 on the ink cartridge assembly 200 and the internal reading device of the printer, ensuring accurate positioning and identification between the ink cartridge assembly 200 and the reading device, and laying a solid foundation for subsequent inkjet printing operations of the ink cartridge assembly 200. Simultaneously, the fact that at least a portion of the chip 212 covers the side wall of the ink cartridge 100 enhances the positioning effect of a new ink cartridge 100 on the printhead 21, ensuring the accuracy of the ink cartridge 100's placement on the printhead 21.

[0102] The printhead 21 also includes a nozzle 213, which is disposed on the bottom surface of the printhead 21 away from the ink cartridge 100, and is used to spray ink flowing in from the ink inlet 211. In this embodiment, the nozzle 213 and the ink cartridge 100 are respectively disposed on two opposite sides of the printhead 21, which facilitates the printhead 21 in receiving ink and maintaining the normal working condition of the ink cartridge assembly 200.

[0103] like Figure 1 and Figure 2The images shown are exploded views of the color ink cartridge assembly 200 and the black ink cartridge assembly 200, respectively. The difference between the color ink cartridge assembly 200 and the black ink cartridge assembly 200 is as follows:

[0104] First, in the color ink cartridge assembly 200, the internal structure of the ink cartridge 100 includes multiple sponge chambers 11 and ink chambers 12. In this embodiment, the three in the middle are sponge chambers 11, and the remaining peripheral ones are ink chambers 12. The specific internal structure of the color ink cartridge assembly 200 can be seen in Embodiment 1, and will not be repeated here. In the black ink cartridge assembly 200, the interior of the ink cartridge 100 includes only one sponge chamber 11 and two ink chambers 12. For details, please refer to... Figure 7 As shown, the center of the ink cartridge 100 is a sponge chamber 11, and the two sides of the sponge chamber 11 are ink chambers 12. The ink outlet 111 of the ink cartridge 100 is also connected to the sponge chamber 11 to ensure the uniformity of ink flow.

[0105] Secondly, in the color ink cartridge assembly 200, the print head 21 is provided with multiple ink inlets 211, and each ink inlet 211 corresponds to an ink outlet 111 in the sponge chamber 11 inside the ink cartridge 100, ensuring that inks of various colors are not contaminated; while in the black ink cartridge assembly 200, the print head 21 is provided with only one ink inlet 211, which also corresponds to an ink outlet 111 in the sponge chamber 11 inside the ink cartridge 100, ensuring normal ink flow.

[0106] Furthermore, as a preferred embodiment, such as Figures 12-15 As shown, a first connecting part 15 is provided on the side of the ink cartridge 100 near the print head 21, and a second connecting part 215 is provided on the side of the print head 21 near the ink cartridge 100 and corresponding to the first connecting part 15, wherein the first connecting part 15 and the second connecting part 215 are adapted to each other.

[0107] In this embodiment, the use of this structural form, compared with the previous method of using glue, and the matching connection of the first connecting part 15 and the second connecting part 215, can make the ink cartridge 100 and the print head 21 more securely connected, avoiding the problems of weak glue bonding and easy detachment of ink cartridge 100 in the past.

[0108] In this embodiment, the first connecting part 15 is a snap-fit, located at the bottom of the ink cartridge 100 near the printhead 21, and the second connecting part 215 is a slot, located on the top surface of the printhead 21 near the ink cartridge 100; the two are compatible. Specifically, in the color ink cartridge assembly, the gasket 22 on the printhead 21 can be provided with a slot according to the snap-fit ​​structure, which also facilitates the installation of the gasket 22 on the printhead 21, resulting in a compact structure.

[0109]

Example 2

[0110] like Figure 16 Figure 17 As shown, the difference between the ink cartridge assembly 200 in this embodiment and the ink cartridge assembly 200 in Embodiment 1 lies in the different structural form of the printhead 21, as detailed below:

[0111] In the vertical direction, the ink cartridge 100 and the print head 21 are stacked in sequence. The ink outlet 111 of the ink cartridge 100 and the ink inlet 211 of the print head 21 are connected. The ink outlet 111 of each color should correspond to the ink inlet 211 of the print head 21 respectively. That is, the bottom of the ink cartridge 100 is in the shape of a cuboid or cube prism. Only at least part of the chip 212 protrudes from the highest horizontal plane where the ink inlet 211 is located. In other words, part of the chip 212 is installed on the side wall of the print head 21, and the other part of the chip 212 is attached to the ink cartridge 100.

[0112] After the ink cartridge 100 is placed on the print head 21, the two are connected by adhesive bonding. That is, the adhesive is applied to the edge between the print head 21 and the ink cartridge 100, which ensures the tightness of the connection between the two.

[0113] In this embodiment, this structural form makes the processing of the printhead 21 and the ink cartridge assembly 200 more convenient, and the positioning chip on the side of the printhead 21 is retained, which makes the printhead 21 more complete and has a higher yield. This will not damage the internal structure of the printhead 21, and will also avoid problems such as damage to the circuit board on the chip 212 and broken circuits.

[0114]

Example 3

[0115] like Figures 18-19 As shown, the difference between the ink cartridge assembly 200 in this embodiment and the ink cartridge assembly 200 in Embodiment 1 lies in the different structural forms of the ink cartridge 100 and the printhead 21, as detailed below:

[0116] The printhead 21 includes the side wall where the chip 212 is located and its opposite side wall. At the same time, the printhead 21 also includes the cell 214 where the ink inlet 211 is located and the cell 214 corresponding to the ink chamber 12 of the ink cartridge 100. That is to say, the structure of the printhead 21 only includes the side wall where the chip 212 is located and its opposite side wall, and all the cells 214 between the two side walls corresponding to each chamber of the ink cartridge 100.

[0117] The structure of the ink cartridge 100 includes all the chambers inside the ink cartridge 100 and the adjacent side wall of the side wall where the chip 212 is located when the ink cartridge 100 is connected to the print head 21, as well as its opposite side wall. In other words, after the ink cartridge 100 and the print head 21 are fully installed, the two side walls of the print head 21 and the two side walls of the ink cartridge 100 can be arranged to form a cuboid or cube prism.

[0118] In this embodiment, this structural form enhances the aesthetics of the ink cartridge assembly 200. At the same time, the two side walls of the ink cartridge 100 can be precisely snapped onto the print head 21, enhancing the reliability of the connection between the ink cartridge 100 and the print head 21.

[0119]

Example 4

[0120] like Figure 20 As shown, a processing technology for an ink cartridge assembly 200 is disclosed. This processing technology is used to process the ink cartridge assembly 200 of any one of embodiments 1-3 described above. The processing technology includes the following steps:

[0121] S11. Preliminary processing of the partition plate 13 between the internal chambers of the ink cartridge 100;

[0122] S12. Machining the plane where the ink outlet 111 is located inside the ink cartridge 100;

[0123] S13. Cut the side wall adjacent to the side wall where the chip 212 is located on the ink cartridge 100 and its opposite side wall.

[0124] S14, cut the remaining cells 214 of the printhead 21, and only save the cell 214 where the ink inlet 211 is located;

[0125] S15. Install the ink cartridge with a transparent outer wall onto the print head.

[0126] In a preferred embodiment, the following steps are included before step S11: after the ink cartridge 100 opens the ink cartridge cover 14, the plane between the ink cartridge 100 and the ink cartridge cover 14 is milled flat.

[0127] In a preferred embodiment, a CNC engraving machine is used in steps S11-S13, and a milling cutter with a diameter of 2mm is used in step S13. A saw is used in steps S14-S15.

[0128] In a preferred embodiment, after step S15, for cell 214 where ink inlet 211 is located, a saw is used to remove the grid around ink inlet 211, so that the new ink cartridge 100 can be embedded and locked onto ink inlet 211 of printhead 21. At the same time, the bottom of the step where ink inlet 211 is located is machined down a little, that is, the height of ink inlet 211 is a little higher. When the new ink cartridge 100 is placed on ink inlet 211, the pad 22 is ensured to have a certain thickness. The pad 22 provides force support for ink cartridge 100 placed on printhead 21, increases the force of pad 22 on ink cartridge 100, and avoids positional displacement of ink cartridge 100 relative to ink inlet 211 of printhead 21, which would lead to ink leakage and other problems, thereby increasing the yield of ink cartridge assembly 200.

[0129] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
