Description

Technical Field

[0001] This application relates to the field of printing technology, and more particularly to a recyclable consumable box. Background Technology

[0002] Ink cartridges, as a type of consumable, are key components that enable the output function of printing devices. To reduce the waste of consumable resources, recycling is achieved by cleaning discarded ink cartridges, refilling them with ink, and adding a programmable adapter chip to the original chip.

[0003] However, since the original chip and the adapter chip in the current regenerable consumable box are laid out on the surface of the receiving part in a flat or side-by-side manner, the consumable box usually needs to be modified to open a larger receiving part, which not only occupies a lot of space, but also affects the layout of components such as ink outlet pipes and ink storage structure; and the welding interface of the two and the storage element of the adapter chip are exposed without protection. When subjected to impact, the interface is easy to break and the brittle protective shell of the storage element is easy to break and expose. As a result, it may malfunction due to contamination with impurities, or even fall off the substrate, causing the electrical wiring to break and damaging the adapter chip. Utility Model Content

[0004] The purpose of this application is to provide a recyclable consumable box to solve the problems of high modification costs, redundant space occupation, insufficient protection of chip soldering interfaces and storage components, and easy damage to electrical performance. This application provides a recyclable consumable box, including a housing and an electrical connection assembly disposed on the housing, the recyclable consumable box comprising: A receiving portion is provided on the housing, the receiving portion including a bearing area and a hollow cavity, the hollow cavity being recessed within the bearing surface where the bearing area is located, and the bearing area surrounding the hollow cavity; The electrical connection assembly includes a first chip and a second chip that are electrically connected. The second chip includes a first base that is electrically connected to the first chip and a second base that has a second storage element. The first chip and the first base are sequentially disposed on the bearing area along a first direction and cover the opening of the hollow cavity. The second base is at least partially housed within the hollow cavity.

[0005] Compared with the prior art, the recyclable consumable box provided in this application has a hollow cavity that is surrounded by the bearing area and recessed into the bearing surface in the receiving part. At the same time, the first base of the first chip and the second chip in the electrical connection component are arranged sequentially on the bearing area along the first direction and cover the opening of the hollow cavity. The second base of the second chip (including the second storage element) is at least partially housed in the hollow cavity. The receiving part with the hollow cavity provides a space for the second base, so that the first chip and the first base can be compactly arranged in the bearing area along the first direction. This greatly reduces the planar occupation area of ​​the electrical connection component, and there is no need to modify the consumable box body. This avoids squeezing the space of other functional components such as ink dispensing pipes and ink storage structures, and solves the problem of space redundancy. Meanwhile, the concave structure of the hollow cavity and the surrounding design of the support area form a three-dimensional enclosure for the second base containing the second storage element. When subjected to external impact, the impact is buffered by the support area, the first chip, or the first base before being transmitted to the second base, significantly weakening the impact energy and reducing the risk of the second storage element's protective shell shattering or electrical wiring breaking. Furthermore, the connection interface between the first chip and the first base is located within the plane of the support area and is supported and protected by the support area, reducing the probability of interface breakage caused by impact stress concentration and ensuring the stability of the electrical connection. In addition, the first chip and the first base cover the opening of the hollow cavity, which can directly block contaminants such as dust and ink droplets from entering the hollow cavity, preventing the second storage element from experiencing electrical malfunctions due to contaminant adhesion.

[0006] In some alternative configurations, the first base of the second chip is further away from the housing than the first chip; the first chip is located between the first base and the second base to achieve a compact layout of the first and second chips, improving structural compactness. Furthermore, by placing the first chip between the first and second bases, the first chip can act as an intermediate buffer layer, further blocking the transmission path of external impacts to the second base, reducing the probability of the second storage element being damaged by impact.

[0007] In some alternative embodiments, the second chip further includes a bending portion connecting the first base and the second base, the bending portion being configured to bend the second base relative to the first base at a predetermined angle. By providing the bending portion to connect the first base and the second base, the second base (including the second storage element) can fit into the recessed space of the hollow cavity, achieving a compact layout of the electrical connection components, enhancing the overall structural rigidity, and ensuring that the second storage element is completely within the protection range of the hollow cavity, avoiding interference with external components.

[0008] In some alternative embodiments, the first chip includes at least one first contact portion, and at least a portion of the first contact portion is exposed outward through a cutout portion of the second chip. By designing the cutout portion, when the second chip covers the first chip, the cutout portion allows a portion of the first contact portion of the first chip to be directly exposed, enabling connection with the printing device pins without additional contact points, simplifying the electrical connection path and reducing signal loss. At the same time, the cutout portion allows the two chips to be tightly stacked within the mounting portion, eliminating the need to reserve contact space separately for the first chip, further reducing the overall thickness of the electrical connection assembly to better adapt to the thin installation space requirements of the printing device.

[0009] In some alternative embodiments, the second chip further includes at least one back contact portion disposed on the first base, the first contact portion being electrically connected to the back contact portion. By providing at least one back contact portion on the first base of the second chip, the printing stylus can obtain new ink volume information stored in the second storage element through the first contact portion and the back contact portion, allowing the consumable cartridge to be reused.

[0010] In some alternative configurations, the rechargeable cartridge is detachably mounted into a mounting unit of the printing device. This mounting unit includes a first contact pin and a second contact pin. The first contact pin passes through the cutout portion of the second chip and contacts the first contact portion. A second contact portion on the second chip contacts the second contact pin. By providing the cutout portion, the first contact pin can directly contact the first contact portion, allowing the printer to obtain new ink volume information from the second storage element through the first contact portion and its electrically connected back contact portion. Furthermore, by providing a guide channel for the first contact pin, the cutout portion ensures precise alignment of the first contact pin with the first contact portion, avoiding pin misalignment and poor contact due to installation deviations. Simultaneously, the independent contact design between the second contact portion and the second contact pin allows contact pins with different functions (such as data contact pins and reset contact pins) to correspond to specific contact portions, reducing the risk of signal crosstalk and improving installation convenience.

[0011] In some alternative configurations, the first contact portion can be a data contact portion, a clock contact portion, a ground contact portion, and a power contact portion, while the second contact portion can be a reset contact portion. By concentrating the core functional signals (data, clock, ground, and power) on the first contact portion and keeping the reset signal independent of the second contact portion, mutual interference between different types of signals transmitted on the same contact portion can be avoided. This ensures the accuracy of ink volume data and control command transmission during high-speed printing.

[0012] In some alternative configurations, in the second direction, the second contact portion is located between multiple first contacts. By positioning the second contact portion between multiple first contacts, the pressure can be evenly distributed across the entire contact area when the stylus of the printing device contacts the contact portion, avoiding unilateral force offset caused by the contact portion being concentrated on one side, and reducing the risk of chip deformation and detachment due to uneven force. Furthermore, when the second contact portion is a reset contact portion, the reset signal, as a control trigger signal, is located between multiple functional signal contacts. It can form an electromagnetic shielding effect through the first contacts on both sides (such as grounding contacts), reducing the influence of external electromagnetic interference on the reset signal and avoiding chip restart and data transmission interruption caused by abnormal reset signal.

[0013] In some alternative embodiments, the first chip further includes a first storage element, at least a portion of which is housed within the hollow cavity, and a second storage element is also housed within the hollow cavity. By housing the first and second storage elements within the hollow cavity, the concave structure of the cavity and the surrounding protection of the support area prevent damage to the first and second storage elements from external impacts, dust, and ink droplets. Simultaneously, the design of embedding the first storage element within the hollow cavity fully utilizes the three-dimensional space of the receiving portion, avoiding its occupation of additional planar area in the support area, optimizing the spatial layout of the electrical connection components, and achieving the design requirements for miniaturization and compact structure of the recyclable consumable box.

[0014] In some alternative embodiments, the recyclable consumable box further includes a buffer section disposed between the first chip and the second base. By providing a buffer section as secondary protection, the first and second storage elements located within the hollow cavity are further protected. When the recyclable consumable box is subjected to external impact, if the box body has a limiting part (such as a raised structure on the box body), the limiting part will first absorb most of the impact energy; when the residual impact energy that has not been completely attenuated is transmitted to the hollow cavity, the buffer section can further absorb this part of the energy through its own elastic deformation, effectively preventing the second base from directly colliding with the inner wall of the hollow cavity. Simultaneously, the buffer section can also limit the second base, restricting its swaying amplitude during transportation and preventing the electrical traces between the second storage element and the substrate from loosening due to swaying.

[0015] In some alternative embodiments, the remanufactured consumable cartridge also includes an ink outlet, which, along the second direction, is located on the same side of the remanufactured consumable cartridge as the receiving portion. By aligning the ink outlet and the receiving portion on the same side, the signal transmission path between the electrical connection component and the ink outlet can be significantly shortened, effectively reducing signal delay and improving the printing device's control accuracy over ink output. Secondly, this same-side layout avoids signal lines crossing multi-functional areas, reducing the risk of lines being damaged by pressure from ink reservoirs or other components. Furthermore, this layout allows for a more compact overall structure of the remanufactured consumable cartridge, fulfilling the design requirements for miniaturization and structural compactness.

[0016] In some alternative embodiments, the regenerated consumable cartridge further includes an ink reservoir, and the hollow cavity is connected to the space containing the ink reservoir or at least a portion thereof. Attached Figure Description

Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0021] Furthermore, 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly specified. "Several" means one or more, unless otherwise expressly specified.

[0022] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", 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 noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] Printing equipment and other image forming devices are common office equipment. Different models of printing equipment require corresponding ink cartridges (a type of consumable cartridge), and the consumable cartridge is a key component for enabling the printing equipment to output. When the ink in the consumable cartridge is exhausted, it is traditionally discarded, resulting in a significant waste of consumable resources. Currently, discarded consumable cartridges are often reused through recycling methods. The specific process includes cleaning the discarded consumable cartridge and refilling it with ink. However, since the original chip of the discarded consumable cartridge cannot be programmed with new ink volume information, an adapter chip that can program information needs to be added to the original chip, thus creating a recycled consumable cartridge.

[0025] In current technology, the consumable cartridge has a receiving portion for mounting a regenerated chipset (including the original chip and an adapter chip), and the upper surface of the receiving portion has a groove. One end of the adapter chip, which has a storage element, extends to the upper surface of the receiving portion in a flat or side-by-side arrangement with the original chip, and the storage element is placed within the groove. In this structural design, because the regenerated chipset is relatively large, the structure of the consumable cartridge needs to be redesigned. Specifically, a larger receiving portion needs to be created on the cartridge to mount the regenerated chip assembly, occupying a significant amount of space and causing unnecessary waste. This also affects the normal installation and layout of other functional components (such as ink delivery lines and ink storage structures).

[0026] Furthermore, because the adapter chip and the original chip are mounted on the consumable box in a flat or side-by-side arrangement, the solder joints between them and the memory element of the adapter chip are exposed on a large surface area without effective support or protection. When the consumable box is subjected to external impact stress (such as bumps during long-distance transportation, accidental drops during use, or collisions during equipment installation or disassembly), the solder joints are prone to bending or even breakage due to stress concentration. At the same time, the outer protective shell of the memory element is made of brittle material, which is prone to shattering or severe damage to the packaging structure after being subjected to impact or shock, resulting in the memory element being completely exposed to the external environment. The memory element itself lacks an effective physical protective barrier and is easily adhered to by dust, ink, or other conductive media, or its electrical function may be abnormal due to surface scratches, seriously affecting its electrical performance stability. In more serious cases, the memory element may detach directly from the substrate of the adapter chip, causing the electrical traces between the memory element and the substrate to break, leading to irreversible damage to the adapter chip and causing some of its functions to fail.

[0027] To overcome the above problems, this application provides a recyclable consumable box. By optimizing the structural design of the recyclable consumable box, the problems of space redundancy, susceptibility of storage elements to impact damage, and interference with electrical performance in existing recyclable consumable boxes are solved.

[0028] Figure 1 A partial structural schematic diagram of a printing apparatus 100 provided in an exemplary embodiment of this application is shown. For example... Figure 1 As shown, the printing device 100 provided in the exemplary embodiment of this application includes: a mounting unit 110, a stylus assembly 120, and a remanufactured consumable box (not shown in the figure). The stylus assembly 120 is disposed on the mounting unit 110, and the remanufactured consumable box is connected to the stylus assembly 120 and the mounting unit 110.

[0029] In some alternative methods, such as Figure 1 As shown, the mounting unit 110 can adopt a drawer-type structure. The mounting unit 110 has four independent mounting positions for mounting remanufactured consumable cartridges. Each mounting position can be provided with an ink supply part 111, a stylus assembly 120, and a connecting part 112. The ink supply part 111 is used to mate with the ink outlet 250 of a corresponding remanufactured consumable cartridge. The connecting part 112 matches the limiting part 212 of the remanufactured consumable cartridge. The two cooperate to fix and correct the position of the remanufactured consumable cartridge.

[0030] In some alternative methods, Figure 2 A schematic diagram of the structure of a stylus assembly 120 provided according to an exemplary embodiment of this application is shown. Figure 1 and Figure 2As shown, the aforementioned contact assembly 120 may include a contact holder 121 and a plurality of contacts 122. The plurality of contacts 122 includes at least a first contact 1221 and a second contact 1222. The first contact 1221 is at least one of a data contact, a clock contact, a reset contact, a ground contact, and a power contact. For example, the first contact 1221 may be a reset contact, and the second contact 1222 may be any of the remaining contacts other than the reset contact. Alternatively, the first contact 1221 may be at least one of a data contact, a clock contact, a reset contact, a ground contact, a power contact, a high-voltage contact, and a short-circuit detection contact, and the second contact 1222 may be any of the remaining contacts other than the first contact 1221. Preferably, in this embodiment, the number of first contacts 1221 is four, specifically a data contact, a clock contact, a ground contact, and a power contact, and the number of second contacts 1222 is one, specifically a reset contact.

[0031] Figure 3 A schematic diagram of the structure of a first recyclable consumable cartridge 200 provided according to an exemplary embodiment of this application is shown. Figure 3 As shown, in order to better illustrate the regenerated consumable box 200, a coordinate system is established: the width direction of the regenerated consumable box 200 is the X-axis direction (second direction), the length direction of the regenerated consumable box 200 is the Y-axis direction (first direction), and the height direction of the regenerated consumable box 200 is the Z-axis direction (third direction). The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0032] like Figure 3 As shown, the aforementioned remanufactured consumable cartridge 200 includes a housing 210, an electrical connection assembly 220 disposed on the housing 210, and an ink storage section 230 for storing ink. The remanufactured consumable cartridge 200 also includes a receiving section 240 disposed on the housing 210.

[0033] In one example, such as Figure 3 As shown, the housing 210 of the regenerable consumable cartridge 200 may have a recessed structure 211, and the receiving portion 240 may be provided at the recessed structure 211. Furthermore, the recessed structure 211 may also include a limiting portion 212 for limiting the connection position between the regenerable consumable cartridge 200 and the stylus assembly 120 described above. Specifically, along the second direction (X-axis direction), the limiting portion 212 may be formed on the two sidewalls of the recessed structure 211, and the limiting portion 212 is configured to form a recess along the first direction (Y-axis direction). The mounting unit 110 may have engaging portions 112 on both sides of the stylus assembly 120 for cooperating with the limiting portion 212 to ensure stable electrical contact between the stylus assembly 120 and the corresponding contact portions on the electrical connection assembly 220.

[0034] Figure 4 It shows Figure 3A magnified view of region A in the middle. (See image below.) Figure 3 and Figure 4 As shown, the receiving portion 240 includes a supporting area 241 and a hollow cavity 242. The supporting area 241 is a region used to support the first chip 221 and the second chip 222. The supporting area 241 includes a supporting surface 2411, which is used to contact the back side of the first substrate 2212 on the first chip 221, thereby supporting the first chip 221 and the second chip 222. Alternatively, the supporting surface 2411 can also support the second chip 222, as long as it can support the first chip 221 and the second chip 222. In addition, the supporting area 241 may also include a receiving area recessed from the housing 210 (e.g., Figure 4 As shown, the bottom surface of the receiving area is a bearing surface 2411, and the receiving area is used to accommodate at least a portion of the first chip 221 or the second chip 222. The hollow cavity 242 is recessed within the bearing surface where the bearing area 241 is located, and the bearing area 241 surrounds the hollow cavity 242. An adhesive unit (not shown in the figure) is provided on the bearing area 241, and the electrical connection assembly 220 can be connected to the bearing area 241 through the adhesive unit. This adhesive unit can be an adhesive strip or a viscous hot-melt coating, etc., and is not limited to these.

[0035] In one example, such as Figure 3 and Figure 4 As shown, the aforementioned receiving portion 240 can be a hollow structure, formed by a support area 241 enclosing a hollow cavity 242 located at the center of the hollow structure. The support area 241 can be a planar structure, its outline adapted to the overall dimensions of the first base 2221 of the first chip 221 and the second chip 222. The hollow cavity 242 is recessed away from the support area 241, forming an embedded space for accommodating the second base 2223. Its dimensions can be designed according to the dimensions of the second storage element 2222, and are not limited here. The hollow cavity 242 communicates with the ink storage portion 230 or at least a portion of the space containing the ink storage portion 230, thereby increasing design flexibility.

[0036] In one example, such as Figure 3 and Figure 4 As shown, the housing 210 has a space for accommodating a portion of the ink storage section 230. The ink storage section 230 also includes an ink outlet 250. After the ink storage section 230 is installed on the housing 210, at least a portion of the ink outlet 250 is accommodated in the ink outlet accommodating section 250a.

[0037] Figure 5 This illustration shows a schematic diagram of the connection state of the first chip 221 and the second chip 222 provided in an exemplary embodiment of this application. Figure 6 This application illustrates a schematic diagram of the structure of the second chip 222 provided in an exemplary embodiment. Figure 1 .like Figures 3-6As shown, the above-mentioned electrical connection component 220 includes a first chip 221 and a second chip 222 that are electrically connected. The second chip 222 includes a first base 2221 that is electrically connected to the first chip 221 and a second base 2223 that is provided with a second storage element 2222. The first chip 221 and the first base 2221 are sequentially disposed on the bearing area 241 along the first direction (i.e., the Y-axis direction) and cover the opening 2421 of the hollow cavity 242. The second base 2223 is at least partially accommodated in the hollow cavity 242.

[0038] In one example, the first chip can be the original chip, used to store information such as the original consumable cartridge's manufacturing date and model identification code. The second chip can be an adapter chip, used to store information such as new ink volume and communication programs with the printing device. The second chip can have a first base and a second base. The first base is used to connect to the original chip, and the second base has a second storage element. The second base with the storage element is located within a hollow cavity, and the opening of the hollow cavity is covered by at least a portion of the first chip and / or at least a portion of the first base. At least one of the first base and the second base of the first chip and the second chip can be constructed as a flexible substrate.

[0039] Therefore, the recyclable consumable box provided in this application embodiment has a hollow cavity surrounded by the bearing area and recessed in the bearing surface in the receiving part. At the same time, the first base of the first chip and the second chip in the electrical connection component are arranged sequentially on the bearing area along the first direction and cover the opening of the hollow cavity. The second base of the second chip (including the second storage element) is at least partially housed in the hollow cavity. The receiving part with the hollow cavity provides a space for the second base, so that the first chip and the first base can be compactly arranged in the bearing area along the first direction. This greatly reduces the planar occupation area of ​​the electrical connection component. There is no need to modify the consumable box body, thereby avoiding the encroachment on the space of other functional components such as ink outlet pipes and ink storage structures, and solving the problem of space redundancy. Meanwhile, the concave structure of the hollow cavity and the surrounding design of the support area form a three-dimensional enclosure for the second base containing the second storage element. When subjected to external impact, the impact is buffered by the support area, the first chip, or the first base before being transmitted to the second base, significantly weakening the impact energy and reducing the risk of the second storage element's protective shell shattering or electrical wiring breaking. Furthermore, the connection interface between the first chip and the first base is located within the plane of the support area and is supported and protected by the support area, reducing the probability of interface breakage caused by impact stress concentration and ensuring the stability of the electrical connection. In addition, the first chip and the first base cover the opening of the hollow cavity, which can directly block contaminants such as dust and ink droplets from entering the hollow cavity, preventing the second storage element from experiencing electrical malfunctions due to contaminant adhesion.

[0040] In some alternative methods, such as Figures 3-6As shown, the first base 2221 of the second chip 222 is further away from the housing 210 than the first chip 221. The first chip 221 is located between the first base 2221 and the second base 2223 to achieve a compact layout of the first chip 221 and the second chip 222, thus improving the structural compactness. Furthermore, by placing the first chip 221 between the first base 2221 and the second base 2223, the first chip 221 can act as an intermediate buffer layer, further blocking the transmission path of external impacts to the second base 2223, and reducing the probability of the second storage element 2222 being damaged by impact.

[0041] In some alternative methods, such as Figures 3-6 As shown, the second chip 222 further includes a bending portion 2224, which connects the first base 2221 and the second base 2223. The bending portion 2224 is configured to bend the second base 2223 relative to the first base 2221 at a predetermined angle, so as to at least partially accommodate it within the hollow cavity 242. It should be understood that the material of the bending portion 2224 can be a rigid material, a rigid material with partial flexible treatment, or a flexible material, etc., and there are no restrictions here. Its bending angle can be designed according to the concave direction of the hollow cavity 242, and there are no restrictions here, as long as the second base 2223 can extend into the hollow cavity 242. By setting a bending portion 2224 to connect the first base 2221 and the second base 2223, the second base 2223 with the second storage element 2222 can fit into the recessed space of the hollow cavity 242, realizing a compact layout of the electrical connection assembly 220, enhancing the overall structural rigidity, and ensuring that the second storage element 2222 is completely within the protection range of the hollow cavity 242, avoiding interference with external components.

[0042] In some alternative methods, such as Figures 3-6 As shown, at least a portion of the first chip 221 and / or at least a portion of the first base 2221 cover the opening 2421 to ensure that the opening 2421 of the hollow cavity 242 is always covered, so that the hollow cavity 242 is in a relatively sealed space, thereby blocking most external contaminants (such as dust and ink droplets) from entering the hollow cavity 242 and preventing the second storage element 2222 from experiencing electrical malfunctions due to contaminant adhesion.

[0043] In one example, when the projected area of ​​the first chip at the corresponding opening on the bearing surface is greater than the projected area of ​​the first base on the bearing surface, the first chip can cover the opening; when the projected area of ​​the first base at the corresponding opening on the bearing surface is greater than the projected area of ​​the first chip on the bearing surface, the first base can cover the opening; when the area where the projected area of ​​the first chip at the corresponding opening on the bearing surface and the projected area of ​​the first base at the corresponding opening on the bearing surface are joined together is located at the opening, the opening can be covered by both the first chip and the first base.

[0044] In some alternative methods, such as Figures 3-6 As shown, the area of ​​the orthographic projection of the second base 2223 onto the bearing surface is smaller than the area of ​​the orthographic projection of the opening 2421 onto the bearing surface. This ensures that the second base 2223 can smoothly pass through the opening 2421 and enter the hollow cavity 242, avoiding assembly interference. Simultaneously, a gap is formed between the second base 2223 and the inner wall of the opening 2421 to prevent installation difficulties or stress concentration caused by excessively tight dimensions. Furthermore, when the regenerated consumable box 200 is impacted, the gap can buffer some of the vibration energy, protecting the second storage element 2222.

[0045] In some alternative methods, such as Figures 3-6 As shown, the first chip 221 includes a first storage element 2211, at least a portion of which is housed within a hollow cavity 242. A second storage element 2222 is also housed within the hollow cavity 242. The first storage element 2211 and the second storage element 2222 can be arranged opposite each other in a direction perpendicular to the bearing surface (see reference). Figure 5 By housing the first storage element 2211 and the second storage element 2222 within the hollow cavity 242, and relying on the concave structure of the hollow cavity 242 and the surrounding protection of the bearing area 241, damage to the first storage element 2211 and the second storage element 2222 from external impacts, dust, and ink droplets can be avoided. Simultaneously, by arranging the first storage element 2211 and the second storage element 2222 opposite each other in a direction perpendicular to the bearing surface, the installation distance between the two storage elements (first storage element 2211 and second storage element 2222) and the length of the electrical connection lines between them are shortened, thereby reducing electromagnetic interference and delay issues during signal transmission and improving the efficiency of the printing device 100 in reading ink volume information and completing data interaction. Furthermore, the design of embedding the first storage element 2211 into the hollow cavity 242 fully utilizes the three-dimensional space of the receiving part 240, avoiding its occupation of additional planar area in the bearing area 241, optimizing the spatial layout of the electrical connection assembly 220, and achieving the design requirements of miniaturization and compact structure of the regenerated consumable box 200.

[0046] In one example Figure 7This application illustrates a schematic diagram of the structure of the first chip 221 provided in an exemplary embodiment. Figure 1 ,like Figures 3-7 As shown, the first chip 221 may include a first substrate 2212, and a first storage element 2211 is disposed on the first substrate 2212. At least a portion of the first storage element 2211 is located in the hollow cavity 242 and is arranged facing the second storage element 2222. By adopting a short interconnect coupling connection between the first storage element 2211 and the second storage element 2222, the risk of signal reflection, crosstalk and electromagnetic interference is reduced, and the quality and integrity of high-frequency signals are improved. Compared with the planar layout method described above, the layout method of this application has higher heat dissipation efficiency, which is beneficial to temperature cycling and avoids the situation where the electrical performance of the first storage element 2211 and the second storage element 2222 degrades due to excessive temperature.

[0047] In some alternative methods, such as Figures 3-7 As shown, the second storage element 2222 can also be disposed on the side of the second base 2223 away from the first chip 221. By disposing the second storage element 2222 on the side away from the first chip 221, signal interference between the second storage element 2222 and the first chip 221 can be reduced, ensuring the signal transmission stability of the electrical connection component 220.

[0048] In some alternative methods, such as Figures 3-7 As shown, to further prevent scratches on the surface of the storage elements (first storage element 2211, second storage element 2222) or cracking of the protective shell due to pressure, the aforementioned recyclable consumable box 200 may also include a buffer section (not shown in the figure), which is disposed between the first chip 221 and the second base 2223. The buffer section may be made of silicone, rubber, or foam. By providing a buffer section between the first chip 221 and the second base 2223, mutual contact or squeezing between the two is prevented, which could damage or disconnect the wiring on the first storage element 2211, the second storage element 2222, and the second chip 222. At the same time, the buffer section can also limit the second base 2223, restricting its shaking amplitude during transportation and preventing loosening of the electrical wiring between the second storage element 2222 and the second base 2223 due to shaking.

[0049] In some alternative methods, such as Figures 3-7As shown, the aforementioned regenerated consumable cartridge 200 also includes an ink outlet 250. Along the second direction (i.e., the X-axis direction), the ink outlet 250 and the receiving part 240 are both located on the same side of the regenerated consumable cartridge 200. By setting the ink outlet 250 and the receiving part 240 on the same side, the signal transmission path between the electrical connection component 220 and the ink outlet 250 can be significantly shortened, effectively reducing signal delay and improving the control accuracy of the printing device 100 on the ink output. Secondly, the same-side layout can avoid signal lines crossing the multi-functional area, reducing the risk of the lines being squeezed and damaged by other components such as the ink reservoir bag. In addition, this layout can also make the overall structure of the regenerated consumable cartridge 200 more compact, realizing the design requirements of miniaturization and compact structure of the regenerated consumable cartridge 200.

[0050] In some alternative methods, Figure 8 A schematic diagram of the structure of a second type of recyclable consumable cartridge 200 provided in an exemplary embodiment of this application is shown. Figures 3-8 As shown, the aforementioned regenerated consumable cartridge 200 also includes a housing 260 (equivalent to the housing 210 mentioned above) and an ink outlet 250. Both the ink outlet 250 and the receiving portion 240 are located on the housing 260, and along the third direction (i.e., the Z-axis direction), the ink outlet 250 and the receiving portion 240 are located on the same side of the regenerated consumable cartridge 200. In this case, the ink storage portion 230 can be constructed as a flexible pouch structure and disposed inside the housing 260.

[0051] In some alternative methods, Figure 9 This application illustrates a schematic diagram of the structure of the first chip 221 provided in an exemplary embodiment. Figure 2 ; Figure 10 This application illustrates a schematic diagram of the structure of the second chip 222 provided in an exemplary embodiment. Figure 2 .like Figures 3-10 As shown, the first chip 221 further includes a first contact portion 2213, and the second chip 222 further includes a second contact portion 22212 disposed on the first base 2221. The first base 2221 may include a second substrate 22211 and a second contact portion 22212. The second contact portion 22212 is located on the reverse side of the second substrate 22211, and the second substrate 22211 at least partially covers the first substrate 2212 (see reference). Figure 5The first base 2221 of the second chip 222 is further away from the housing 210 / 260 than the first chip 221; the first chip 221 is located between the first base 2221 and the second base 2223 of the second chip 222. The first chip 221 also includes a first storage element 2211. As described above, the first storage element 2211 is used to store information related to the original consumable box. This information includes, but is not limited to, the manufacturing date of the original consumable box, the identification information of the original consumable box, and the program information used. The first contact 2213 is electrically connected to the first storage element 2211, and the printing device 100 can read the information stored in the first storage element 2211 through the first contact 2213. The second chip 222 also includes a second storage element 2222. As described above, the second storage element 2222 is used to store new ink volume information and processing programs for communication with the printing device 100 and the original chip (first chip 221). The second contact portion 22212, in cooperation with the second storage element 2222, enables communication and data transmission between the adapter chip (second chip 222), the original chip (first chip 221), and the printing device 100, so as to facilitate the adapter chip (second chip 222) to complete the corresponding work and realize the corresponding functions. When the regenerated consumable cartridge 200 is installed in the printing device 100, the second storage element 2222 and the printing device 100 will perform data transmission, confirmation, and data interaction. The two can complete the above work through the connection between the first contact portion 2213 and the second contact portion 22212 and the stylus assembly 120.

[0052] In some alternative methods, such as Figures 3-10 As shown, the second chip 222 also has a cutout portion 22213, and at least a portion of at least one first contact portion 2213 is exposed outward through the cutout portion 22213 of the second chip 222 (see reference). Figure 5 By designing the cutout portion 22213, when the second chip 222 covers the first chip 221, the cutout portion 22213 allows a portion of the first contact portion 2213 of the first chip 221 to be directly exposed, enabling connection with the stylus 122 of the printing device 100 without the need for additional contact points, simplifying the electrical connection path and reducing signal loss. Simultaneously, the cutout portion 22213 allows the two chips (first chip 221 and second chip 222) to be tightly stacked within the receiving portion 240, eliminating the need for separate contact space for the first chip 221, further reducing the overall thickness of the electrical connection assembly 220 to better suit the thin-film installation space requirements of the printing device 100. Preferably, the area of ​​the cutout portion allows the portion of the first contact portion that contacts the printing stylus to be directly exposed.

[0053] In some alternative methods, such as Figures 3-10As shown, the second chip 222 further includes at least one back contact portion 22214 disposed on the first base 2221, and the first contact portion 2213 is electrically connected to the back contact portion 22214. By providing at least one back contact portion 22214 disposed on the first base 2221 on the second chip 222, and the back contact portion 22214 and the first contact portion 2213 being located on different sides of the first base 2221 respectively, the printing stylus can obtain new ink volume information stored in the second storage element through the first contact portion and the back contact portion to the second contact portion, allowing the consumable cartridge to be reused. Furthermore, the electrical connection between the first contact portion 2213 and the back contact portion 22214 can be achieved by welding, abutting, fusion, or a conductive intermediate medium connection, ensuring that electrical signals can be transmitted between the first contact portion 2213 and the back contact portion 22214, and that they are electrically connected.

[0054] In some alternative methods, such as Figures 3-10 As shown, the aforementioned recyclable consumable cartridge 200 is detachably installed into the mounting unit 110 of the printing device 100. The mounting unit 110 includes a first contact pin 1221 and a second contact pin 1222. The first contact pin 1221 passes through the cutout portion 22213 of the second chip 222 and contacts the first contact portion 2213. The second contact portion 22212 on the second chip 222 contacts the second contact pin 1222. Furthermore, by providing a guide channel for the first contact pin 1221 through the cutout portion 22213, it is ensured that the first contact pin 1221 can be accurately aligned with the first contact portion 2213, avoiding contact pin offset and poor contact due to installation deviation. At the same time, the independent contact design of the second contact portion 22212 and the second contact pin 1222 allows contact pins with different functions (such as data contact pins and reset contact pins) to correspond to the matching contact portions respectively, reducing the risk of signal crosstalk and improving installation convenience.

[0055] In some alternative methods, such as Figures 3-10 As shown, the first contact portion 2213 and the second contact portion 22212 correspond to and are in contact with the plurality of contact pins 122. The first contact portion 2213 is a data contact portion, a clock contact portion, a ground contact portion, and a power contact portion; the second contact portion 22212 is a reset contact portion. By concentrating the core functional signals (data, clock, ground, and power) on the first contact portion 2213 and keeping the reset signal independent of the second contact portion 22212, mutual interference between different types of signals transmitted on the same contact portion is avoided. This ensures the accuracy of ink volume data and control command transmission during high-speed printing in the printing device.

[0056] In some alternative methods, such as Figures 3-10As shown, the first contact pin 1221 contacts the first contact portion 2213 on the first chip 221; the first contact pin 1221 passes through the cutout portion 22213 of the second chip 222 and contacts the first contact portion 2213, that is, the contact position of the first contact portion 2213 with the first contact pin 1221 is exposed outward from the cutout portion 22213; the second contact pin 1222 contacts the second contact portion 22212 on the second chip 222. Therefore, the contact position of the second contact portion 22212 with the second contact pin 1222 is no longer on the same plane as the contact position of the first contact portion 2213 with the first contact pin 1221.

[0057] In some alternative methods, such as Figures 3-10 As shown, in the second direction, the second contact portion 22212 is located between multiple first contact portions 2213. By positioning the second contact portion 22212 between multiple first contact portions 2213, when the stylus 122 of the printing device 100 contacts the contact portion, the pressure can be evenly distributed throughout the contact area, avoiding unilateral force offset caused by the contact portion being concentrated on one side, and reducing the risk of chip deformation and detachment due to uneven force. Furthermore, when the second contact portion 22212 is a reset contact portion, the reset signal, as a control trigger signal, is located between multiple functional signal contacts. It can form an electromagnetic shielding effect through the first contact portions 2213 on both sides (such as grounding contacts), reducing the influence of external electromagnetic interference on the reset signal and avoiding chip restart and data transmission interruption caused by abnormal reset signal.

[0058] In one embodiment, the first storage element 2211 of the first chip 221 communicates with the printing device 100 (the transmission path is: the first stylus 1221 of the printing device 100 — the first contact portion 2213 — the back contact portion 22214 — the second storage element 2222). When the printing device 100 needs to perform special tests on the regenerated consumable cartridge 200 (e.g., installation test / short circuit test / other tests), that is, when it detects the special signal sent by the corresponding printing device 100, the second storage element 2222 of the second chip 222 will feed back the corresponding data signal to complete the data transmission, confirmation and data interaction.

[0059] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0060] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
