Description

[0001] This application claims priority to Chinese Patent Application No. 202420595560.5 (the earlier application was filed on March 26, 2024, and its utility model title is "A Consumable Data Rewriting Device and Consumable"). Technical Field

[0002] This utility model relates to the field of printer technology, and in particular to a consumable data rewriting device and consumables. Background Technology

[0003] Upgrading non-original consumables to make them compatible with the upgraded device, ensuring accurate communication between the device and the consumables, is a common technique in electronic products. Consumables such as ink cartridges are an example. Currently, many printing devices use replaceable ink cartridges as ink containers. These cartridges contain chips that communicate with the printer's printhead, enabling the cartridge to function properly.

[0004] In existing technologies, after the device serial number or other data is upgraded, the chip on non-original consumables installed on the device may not be recognized. To make the chip on the non-original consumable compatible with the device, a data rewriting device is needed to upgrade the chip's serial number and other data. During the upgrade process, to ensure a good electrical connection between the consumable and the data rewriting device and to prevent chip upgrade failure, the data rewriting device usually uses a clamping structure to hold and fix the consumable. Under the clamping force, the consumable may be damaged. Utility Model Content

[0047] Reference Figures 1 to 7 As shown, this embodiment provides a consumable data rewriting device, which is detachably connected to the consumable 10.

[0048] Specifically, the consumable 10 is provided with a chip 11; the consumable 10 has a first side 12 and a second side 13 disposed opposite to each other, and a first fastening protrusion 14 is provided on the first side 12 of the consumable 10. The first side 12 and the second side 13 of the consumable 10 can be two opposite surfaces of the consumable 10 along its own length direction. Figure 2 In this context, direction d represents the length direction of consumable 10.

[0049] Specifically, the consumable data rewriting device includes a base 100 and a test component 200. The test component 200 is disposed on the base 100. The base 100 has a first mounting portion 101 and a second mounting portion 102 spaced apart at both ends along a first direction. The first mounting portion 101 is provided with a fastening structure 111. Figure 1In the diagram, direction 'a' is the first direction, which can be the length direction of the consumable data rewriting device.

[0050] When the consumable 10 is installed between the first mounting part 101 and the second mounting part 102, the fastening structure 111 engages with the first fastening protrusion 14, the second mounting part 102 is detachably connected to the second side part 13 of the consumable 10, and the test component 200 is electrically connected to the chip 11.

[0051] In this embodiment, the snap-fit ​​structure 111 engages with the first snap-fit ​​protrusion 14, and the second mounting portion 102 connects to the second side portion 13 of the consumable 10. This allows the consumable 10 to be stably fixed between the first mounting portion 101 and the second mounting portion 102 of the base 100, effectively ensuring a good electrical connection between the test component 200 and the chip 11. Furthermore, the snap-fit ​​structure 111 engages with the first snap-fit ​​protrusion 14, and the second mounting portion 102 is detachably connected to the second side portion 13 of the consumable 10, facilitating the fixation of the consumable 10 and effectively preventing damage to the consumable 10 caused by traditional clamping structures.

[0052] In this embodiment, the second mounting part 102 is provided with a locking structure 121, and the second mounting part 102 is detachably connected to the second side part 13 of the consumable 10 through the locking structure 121. For example, when installing the consumable 10 on the consumable data rewriting device, the locking structure 121 can be connected to the second side part 13 of the consumable 10 first, and then the fastening structure 111 can be engaged with the first fastening protrusion 14; when removing the consumable 10 from the consumable data rewriting device, the fastening structure 111 can be separated from the first fastening protrusion 14 first, and then the locking structure 121 can be separated from the second side part 13 of the consumable 10, which facilitates the installation and removal of the consumable 10.

[0053] In some embodiments, the first mounting portion 101 is rotatably disposed on the base 100 to facilitate the engagement and disengagement between the fastening structure 111 and the first fastening protrusion 14. Of course, the first mounting portion 101 can also be mounted on the base 100 by means of detachable connection, such as by snap-fit ​​or screw fastening.

[0054] For example, the first mounting part 101 can be rotatably connected to the base 100 via the first shaft, and a first elastic element can be provided between the first mounting part 101 and the base 100. The first elastic element can be a torsion spring. The first elastic element can make the first mounting part 101 have a tendency to rotate toward the consumable 10 so that the fastening structure 111 engages with the first fastening protrusion 14.

[0055] In some embodiments, the second mounting portion 102 is rotatably disposed on the base 100 to facilitate a detachable connection between the second mounting portion 102 and the second side portion 13 of the consumable 10. Of course, the second mounting portion 102 can also be mounted on the base 100 by a detachable connection, such as by snap-fit ​​or screw fastening.

[0056] For example, the second mounting part 102 can be rotatably connected to the base 100 via the second shaft, and a second elastic member can be provided between the second mounting part 102 and the base 100. The second elastic member can be a torsion spring. The second elastic member can make the second mounting part 102 have a tendency to rotate toward the consumable 10 so that the locking structure 121 is connected to the second side 13 of the consumable 10.

[0057] In some other embodiments, at least one of the first mounting portion 101 and the second mounting portion 102 may be configured as a plate structure.

[0058] For example, such as Figure 1 and Figure 5 As shown, the first mounting portion 101 includes a first side plate 110, and the first side plate 110 is provided with a fastening structure 111. The base 100 and the first side plate 110 can be integrally formed, facilitating injection molding. In this embodiment, when the consumable 10 is installed between the first mounting portion 101 and the second mounting portion 102, the first side plate 110 can limit the consumable 10, making the electrical connection between the test component 200 and the chip 11 more stable and reliable.

[0059] For example, such as Figure 1 and Figure 5 As shown, the second mounting portion 102 includes a second side plate 120, on which a locking structure 121 is provided. The base 100 and the second side plate 120 can be integrally formed, facilitating injection molding. In this embodiment, when the consumable 10 is installed between the first mounting portion 101 and the second mounting portion 102, the second side plate 120 can limit the consumable 10, and the locking structure 121 further limits and fixes the second side 13 of the consumable 10, effectively ensuring a more stable and reliable electrical connection between the test assembly 200 and the chip 11.

[0060] In one feasible embodiment, the first mounting portion 101 includes a first side plate 110, and the second mounting portion 102 includes a second side plate 120. That is, the base 100, the first side plate 110, and the second side plate 120 can be integrally formed, which facilitates injection molding. Furthermore, when the consumable 10 is installed between the first mounting portion 101 and the second mounting portion 102, at least one of the first side plate 110 and the second side plate 120 can limit the consumable 10, thereby making the electrical connection between the test component 200 and the chip 11 more stable and reliable.

[0061] For example, the first side plate 110 and the second side plate 120 may be located on opposite sides of the base 100 facing the consumable 10 along the first direction to ensure that the consumable data rewriting device has a compact structure.

[0062] In this embodiment, reference is made to Figures 1 to 3 , Figures 5 to 7 As shown, the consumable 10, which can be detachably connected to the consumable data rewriting device, includes, but is not limited to, ink cartridges, toner cartridges, drum units, or ribbon cartridges. In this embodiment, the consumable data rewriting device and the slots on the consumable 10 itself form a snap-fit ​​limit, thereby achieving fixed installation of the consumable 10 relative to the base 100. This allows operators to easily and quickly upgrade the chip 11, thereby adapting non-original consumables to the printer to complete normal printing work.

[0063] In this embodiment, reference is made to Figures 1 to 7 As shown, the consumable 10 is provided with an ink outlet 18, and a protective cover 20 is locked onto the consumable 10. The protective cover 20 is used to block the ink outlet 18, and the protective cover 20 is provided with a cover handle 21.

[0064] Specifically, the protective cover 20 can be snapped onto the consumable 10 via the second snap-fit ​​protrusion 15. In this embodiment, the ink outlet 18 is located near the second side 13 of the consumable 10, and the cover handle 21 is provided with a slot 22. The second snap-fit ​​protrusion 15 can engage with the slot 22 to achieve a locking fit between the consumable 10 and the protective cover 20.

[0065] In some embodiments, such as Figures 1 to 4 As shown, the second side 13 of the consumable 10 is provided with a second fastening protrusion 15; the locking structure 121 is configured as a limiting groove 1211 on the second side plate 120, and the limiting groove 1211 engages with the second fastening protrusion 15. In this embodiment, the protective cover 20 can be removed from the consumable 10 first to prevent the protective cover 20 from interfering with the engagement between the second fastening protrusion 15 and the limiting groove 1211, so that the connection between the second side 13 of the consumable 10 and the locking structure 121 is stable and reliable. Of course, the positions of the second fastening protrusion 15 and the limiting groove 1211 can be interchanged, that is, the second side 13 of the consumable 10 is provided with the limiting groove 1211, and the second side plate 120 is provided with the second fastening protrusion 15.

[0066] In other embodiments, such as Figures 5 to 7As shown, the consumable 10 also has a third side portion 16, which is adjacent to the second side portion 13 of the consumable 10. The locking structure 121 is an end plate 1212 disposed at the end of the second side plate 120 near the third side portion 16 of the consumable 10 and opposite to the base 100. The end plate 1212 extends toward the first side plate 110, and the side of the end plate 1212 facing the base 100 abuts against the third side portion 16 of the consumable 10. That is, the second side portion 13 of the consumable 10 is sandwiched between the base 100 and the end plate 1212, which is stable and reliable. In this embodiment, the second side portion 13 of both the consumable 10 with and without the protective cover 20 can be sandwiched between the base 100 and the end plate 1212.

[0067] In one feasible implementation, when the consumable data rewriting device is used to install consumable 10 with protective cover 20, and the locking structure 121 is an end plate 1212, the second side plate 120 is provided with a clearance hole 122, and the cover handle 21 passes through the clearance hole 122, effectively preventing installation interference between the cover handle 21 and the second side plate 120. The end plate 1212 prevents the cover handle 21 of the protective cover 20 from moving along the second side 13 of the consumable 10 within the clearance hole 122, thus achieving a better limiting and fixing effect.

[0068] In one feasible implementation, when the consumable data rewriting device is used to install the consumable 10 with the protective cover 20, and the locking structure 121 is an end plate 1212, the consumable data rewriting device can be locked and fitted outside the protective cover 20. Specifically, the base 100 is provided with a receiving groove 150, which is used to receive the protective cover 20. That is, without removing the protective cover 20 from the consumable 10, the consumable 10 can be installed on the base 100 for chip 11 upgrade, effectively preventing installation interference between the protective cover 20 and the base 100. The protective cover 20 can abut against the bottom of the receiving groove 150 and cooperate with the end plate 1212 to achieve limiting and fixing of the first side 12 of the consumable 10.

[0069] For example, the length L1 of the receiving groove 150 is greater than the length L2 of the protective cover 20, so as to accommodate the protective cover 20 within the receiving groove 150 and to accommodate the consumable 10 on the base 100 to avoid installation interference. Specifically, a transition surface 151 may be provided on the side wall of the receiving groove 150 away from the second mounting part 102. The transition surface 151 includes, but is not limited to, a rounded corner surface or a chamfered surface, to avoid installation interference and facilitate the insertion of the protective cover 20 into the receiving groove 150.

[0070] In one feasible implementation, such as Figures 1 to 4As shown, the base 100 is provided with a mounting groove 160, and a sealing gasket 300 is provided in the mounting groove 160. The sealing gasket 300 is used to seal the ink outlet 18 to prevent liquid leakage, avoid waste, and prevent contamination of the consumable data rewriting device. In this case, the protective cover 20 is not required, as the sealing gasket 300 and the mounting groove 160 together serve the function of the aforementioned protective cover 20. The mounting groove 160 facilitates the positioning and installation of the sealing gasket 300 and ensures a tight fit between the consumable data rewriting device and the consumable 10. In this embodiment, the locking structure 121 can be a limiting groove 1211 or an end plate 1212.

[0071] Specifically, the mounting groove 160 is located on the side of the base 100 facing the mounting consumable 10.

[0072] For example, the sealing gasket 300 can be made of silicone.

[0073] In this embodiment, reference is made to Figure 1 and Figure 5 As shown, the first side 12 of the consumable 10 is provided with a consumable handle 17, and the consumable handle 17 is provided with a first fastening protrusion 14. Exemplarily, firstly, the consumable handle 17 is pressed to deform it, moving the consumable 10 toward the base 100 and connecting the locking structure 121 to the second side 13 of the consumable 10. This involves either inserting the second fastening protrusion 15 into the limiting groove 1211 or inserting the second side 13 of the consumable 10 between the end plate 1212 and the second side plate 120. Then, the consumable handle 17 is released, restoring its deformation, and the first fastening protrusion 14 engages with the fastening structure 111, thus achieving a convenient and reliable fixed installation of the consumable 10 relative to the base 100. For example, during the process of moving the consumable 10 toward the base 100, the consumable 10 can be slightly tilted so that the length direction of the consumable 10 forms an angle with the length direction of the consumable data rewriting device, which makes it easier to install the consumable 10. The second side plate 120 can abut against the second side 13 of the consumable 10 to ensure that the consumable 10 is stably installed on the base 100.

[0074] In one feasible implementation, the first side plate 110 is inclined toward the side away from the second side plate 120 to make way for the consumable handle 17, which effectively improves the structural compactness of the consumable data rewriting device and facilitates the consumable 10 to be inserted between the first side plate 110 and the second side plate 120.

[0075] For example, a first reinforcing rib 130 is connected between the first side plate 110 and the base 100, which effectively strengthens the connection between the first side plate 110 and the base 100 and effectively prevents the first side plate 110 from deforming.

[0076] For example, the first reinforcing rib 130 may be provided on the side of the base 100 facing the mounting consumable 10 to ensure that the consumable data rewriting device has a compact structure.

[0077] For example, the first reinforcing rib 130 extends to the top of the first side plate 110.

[0078] For example, two first reinforcing ribs 130 are provided, and the two first reinforcing ribs 130 can be located at corresponding side edges of the first side plate 110 along the second direction. Of course, the number of first reinforcing ribs 130 can also be provided, and this application does not limit it. Figure 5 In the diagram, direction b is the second direction, which can be the width direction of the consumable data rewriting device.

[0079] In this embodiment, as Figures 1 to 7 As shown, the fastening structure 111 includes a limiting protrusion 1111, the end face of which is inclined toward the side away from the second side plate 120; wherein, the side of the limiting protrusion 1111 facing the base 100 abuts against the first fastening protrusion 14 to form a snap-fit. During the installation of the consumable 10 onto the base 100, the end face of the inclined limiting protrusion 1111 allows the first fastening protrusion 14 on the consumable handle 17 to easily pass over the limiting protrusion 1111 along its end face and snap into the limiting protrusion 1111.

[0080] In some embodiments, one of the first engaging protrusion 14 and the limiting protrusion 1111 can be replaced by a slot or hole that can engage with the other. Furthermore, depending on the specific structural features of the consumable 10, the engaging structure 111 can also be configured in other structural forms, which are not further limited in this application.

[0081] In this embodiment, as Figure 1 and Figure 5 As shown, the fastening structure 111 also includes a second reinforcing rib 1112. The second reinforcing rib 1112 is disposed on the side of the limiting protrusion 1111 facing the top of the first side plate 110, and the second reinforcing rib 1112 connects the limiting protrusion 1111 and the first side plate 110. The provision of the second reinforcing rib 1112 can enhance the structural strength of the fastening structure 111 and effectively prevent the limiting protrusion 1111 from breaking.

[0082] Specifically, the second reinforcing rib 1112 is located on the side of the limiting protrusion 1111 facing the top of the first side plate 110. The end face of the limiting protrusion 1111 may coincide with the end face of the second reinforcing rib 1112.

[0083] For example, the first side plate 110 is provided with an elongated hole 112. The elongated hole 112 is located on the side of the limiting protrusion 1111 facing the base 100, and one end of the elongated hole 112 extends to the limiting protrusion 1111 along its own length direction, while the other end extends to the base 100. The elongated hole 112 can reduce weight on the one hand, and avoid the first fastening protrusion 14 when installing consumables on the other hand, and can also facilitate the disassembly of consumables 10.

[0084] In this embodiment, reference is made to Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, at least two limiting plates 140 are spaced apart along the second direction on the side of the base 100 facing the mounting consumable 10. The consumable 10 is mounted between the limiting plates 140 and forms a limiting engagement with the limiting plates 140 along the second direction. In this embodiment, when the consumable 10 is mounted between the first mounting part 101 and the second mounting part 102, the sides of the at least two limiting plates 140 facing each other can fit against the sides of the consumable 10 corresponding to each other along the width direction, thereby achieving positioning of the consumable 10 along the second direction and effectively preventing the consumable 10 from tilting relative to the base 100, making the electrical connection between the chip 11 and the test component 200 more stable and reliable. In addition, the at least two limiting plates 140 can also guide the consumable 10 to move toward the base 100, so that the chip 11 can accurately dock with the test component 200. Figure 2 In this context, direction 'e' represents the width direction of consumable 10.

[0085] In one feasible embodiment, the limiting plate 140 is disposed on the side of the base 100 near the first side plate 110, and the limiting plate 140 is fixed to the first side plate 110, which can strengthen the connection between the first side plate 110 and the base 100 and effectively prevent the first side plate 110 and the base 100 from breaking. Both limiting plates 140 are located between the two first reinforcing ribs 130. Of course, the limiting plate 140 can also be disposed at other positions on the base 100, which is not limited in this application.

[0086] For example, the limiting plate 140 is provided with an extension 141, which is connected to the first side plate 110 and extends toward the top of the first side plate 110 to prevent the first side plate 110 from deforming and to ensure the stability of the consumable 10 fixedly installed relative to the consumable data rewriting device.

[0087] In some embodiments, the consumable data rewriting device is provided with at least one base 100. When the consumable data rewriting device is provided with multiple bases 100, multiple consumables 10 can be installed and fixed, enabling simultaneous upgrades of multiple consumables 10.

[0088] In other embodiments, the base 100 is provided with multiple sets of first mounting parts 101, second mounting parts 102 and test components 200 to enable simultaneous upgrade of multiple consumables 10.

[0089] In this embodiment, reference is made to Figures 1 to 7 As shown, the test assembly 200 includes a probe 210 and a terminal block 220. Both the probe 210 and the terminal block 220 are mounted on the base 100. The probe 210 is electrically connected to the terminal block 220. When the consumable 10 is installed between the first mounting portion 101 and the second mounting portion 102, the probe 210 can be electrically connected to the chip 11. For example, the terminal block 220 can be electrically connected to a host computer, and the chip 11 is electrically in contact with the probe 210. That is, the host computer, terminal block 220, probe 210, and chip 11 are sequentially electrically connected to complete the upgrade of the chip 11. The host computer includes, but is not limited to, a computer, tablet, and mobile phone. For example, a storage device can be electrically connected between the terminal block 220 and the probe 210. Upgrade data stored in the storage device can be transmitted to the chip 11 through the probe 210, and the host computer can update the upgrade data stored in the storage device through the terminal block 220.

[0090] For example, probe 210 is disposed on the side of base 100 facing the mounting consumable 10. Probe 210 extends in a third direction. Figure 1 The 'c' direction can be a third direction, which can be the height direction of the consumable data rewriting device.

[0091] For example, the probe 210 is located on the side of the base 100 where the first mounting portion 101 is provided.

[0092] For example, the terminal block 220 may be disposed on the side of the base 100 where the second mounting portion 102 is provided along the first direction.

[0093] For example, a chip 11 is provided at the bottom of the consumable 10, and the chip 11 is disposed near the first side 12 of the consumable 10 to facilitate contact and conduction with the probe 210. In this embodiment, a limiting plate 140 is disposed on the side of the base 100 where the first mounting part 101 is provided. When the consumable 10 is installed between the first mounting part 101 and the second mounting part 102, the chip 11 is located between the two limiting plates 140, which can make the electrical connection between the test component 200 and the chip 11 more stable and reliable.

[0094] Reference Figures 1 to 7As shown, this embodiment also provides a consumable 10, which is detachably connected to the aforementioned consumable data rewriting device. The consumable 10 is provided with a chip 11 and has a first side 12 and a second side 13 disposed opposite to each other. A first fastening protrusion 14 is provided on the first side 12. When the consumable 10 is installed between the first mounting part 101 and the second mounting part 102 of the consumable data rewriting device, the chip 11 is electrically connected to the test component 200 of the consumable data rewriting device. The specific structure of the consumable 10 can be found in the foregoing description and will not be repeated here. In this embodiment, the consumable 10 is conveniently fixed to the consumable data rewriting device and effectively ensures a good electrical connection between the chip 11 and the test component 200.
