[0045] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0046] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0048] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0050] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0051] Figure 1This is a schematic diagram of the structure of an ink cartridge assembly 1. This application embodiment provides an ink cartridge assembly 1 for detachable installation in a printing device (not shown in the figure). The ink cartridge assembly 1 includes an ink cartridge and a chip assembly 12, which is detachably installed in the ink cartridge.

[0052] Figure 2 This is a schematic diagram of the ink cartridge structure. The ink cartridge includes a body 11, which is generally rectangular in shape. The body 11 has an ink storage chamber (not shown in the figure) and an ink outlet 115, which are connected. The ink storage chamber stores ink. When the printing device is printing, the ink in the ink storage chamber can be supplied to the printing device through the ink outlet 115, so that the ink can be sprayed or transferred onto the printing medium (e.g., paper) to complete the printing.

[0053] Figure 3 This is a schematic diagram of the structure of the chip component 12. The chip component 12 is used to record information such as the ink volume and number of times the ink cartridge is used. The chip component 12 can be electrically connected to the printing device, thereby transmitting the ink cartridge information to the printing device.

[0054] In this embodiment, the chip assembly 12 is installed on the housing 11. The chip assembly 12 can be a chip assembly 12 removed from the original ink cartridge and then applied to a new ink cartridge for continued use, thus saving costs; the chip assembly 12 can also be a brand new chip assembly 12.

[0055] Please refer to the reference. Figure 2 and Figure 3 The housing 11 is provided with a chip mounting part 111, and the chip assembly 12 includes a chip body 121 and a chip carrier part 122 connected to each other. The chip carrier part 122 is detachably mounted on the chip mounting part 111.

[0056] At least a portion of the chip mounting portion 111 is an arc-shaped first mating surface 111a, and at least a portion of the chip carrier portion 122 on the side opposite to the chip body 121 is an arc-shaped second mating surface 122a. When the chip carrier portion 122 is mounted on the chip mounting portion 111, the first mating surface 111a and the second mating surface 122a are matched.

[0057] Understandably, when the ink outlet 115 of the ink cartridge is set upwards, the first mating surface 111a refers to the upper surface of the chip mounting part 111, and the second mating surface 122a refers to the lower surface of the chip carrier part 122.

[0058] In this embodiment, by providing a chip mounting part 111 on the housing 11, it can be matched with the disassembled chip assembly 12, so that the chip assembly 12 can be reused in a reasonable manner.

[0059] Meanwhile, when the chip carrier 122 of the chip assembly 12 is installed on the chip mounting part 111, the first mating surface 111a and the second mating surface 122a are in contact. By setting both the first mating surface 111a and the second mating surface 122a as arc-shaped surfaces, the chip carrier 122 and the chip mounting part 111 can be pre-positioned, ensuring the accuracy of the installation of the chip carrier 122 and the chip mounting part 111, and making the chip carrier 122 stably and reliably fixed to the chip mounting part 111.

[0060] In other embodiments, the mating position of the first mating surface 111a and the second mating surface 122a is the connection position between the chip carrier 122 and the chip mounting portion 111. When disassembling the chip carrier 122 and the chip body 121, a disassembly tool is required to separate the chip carrier 122 and the chip mounting portion 111 from the mating position of the first mating surface 111a and the second mating surface 122a. The disassembly tool is generally a circular tool. By setting the first mating surface 111a and the second mating surface 122a as arc-shaped surfaces, the first mating surface 111a and the second mating surface 122a are made to better fit the shape of the disassembly tool, making it easier for the disassembly tool to operate at the connection position of the chip carrier 122 and the chip mounting portion 111, thus facilitating user operation.

[0061] In some embodiments, the disassembly tool can disassemble the chip carrier 122 and the chip mounting portion 111 along the width direction X of the ink cartridge. In this case, a portion of the upper surface of the chip mounting portion 111 along the width direction X of the ink cartridge can be set as a first mating surface 111a, and correspondingly, a portion of the lower surface of the chip carrier 122 along the width direction X of the ink cartridge can be set as a second mating surface 122a.

[0062] Alternatively, in other embodiments, the entire upper surface of the chip mounting portion 111 can be configured as a first mating surface 111a, and correspondingly, the entire lower surface of the chip carrier portion 122 can be configured as a second mating surface 122a.

[0063] Please continue to refer to the reference. Figure 2 and Figure 3 Along the width direction X of the ink cartridge, one end of the chip mounting part 111 is a limiting part, and one end of the chip carrier part 122 is a mating part. The limiting part and the mating part cooperate to limit the installation position of the chip carrier part 122 and the chip mounting part 111, so as to avoid the chip assembly 12 being installed backwards and ensure the accuracy of the reinstallation of the chip assembly 12.

[0064] Figure 4This is a schematic diagram of the cartridge body 11 from another perspective. Along the width direction X of the cartridge, the chip mounting portion 111 is provided with a first end 111b and a second end 111c. Along the length direction Y of the cartridge, the length of the first end 111b is L1, and the length of the second end 111c is L2, where L1 < L2. That is, along the width direction X of the cartridge, the length of one end of the chip mounting portion 111 is shorter than the length of the other end.

[0065] Figure 5 This is a schematic diagram of the chip assembly 12 from another perspective. Along the width direction X of the ink cartridge, the chip carrier portion 122 is provided with a cutting end 122c and a separating end 122b. Along the length direction Y of the ink cartridge, the length of the separating end 122b is L3, and the length of the cutting end 122c is L4, where L3 < L4. That is, along the width direction X of the ink cartridge, the length of one end of the chip carrier portion 122 is shorter than the length of the other end.

[0066] It should be noted that the cutting end 122c of the chip carrier 122 refers to the end into which the disassembly fixture first enters when the chip carrier 122 is removed from the original ink cartridge. The separating end 122b of the chip carrier 122 refers to the end where the chip carrier 122 leaves the original ink cartridge when it is removed from the original ink cartridge.

[0067] Please refer to the reference. Figure 4 and Figure 5 When the chip assembly 12 is installed into the housing 11, the first end 111b of the chip mounting part 111 is correspondingly set to the separation end 122b of the chip carrier part 122, and the second end 111c of the chip mounting part 111 is correspondingly set to the cutting end 122c of the chip carrier part 122. At this time, L1 = L3 and L2 = L4.

[0068] In other embodiments, L3 can be slightly smaller than L1, and L4 can be slightly smaller than L2, as long as it facilitates the identification of the installation of chip assembly 12 and prevents the chip assembly 12 from being installed incorrectly.

[0069] In this embodiment, by limiting the length of the first end 111b of the chip mounting portion 111 to be less than the length of the second end 111c, and limiting the length of the separating end 122b of the chip carrier portion 122 to be less than the length of the cutting end 122c, the first end 111b of the chip mounting portion 111 can only cooperate with the separating end 122b of the chip carrier portion 122, and the second end 111c of the chip mounting portion 111 can only cooperate with the cutting end 122c of the chip carrier portion 122. This restricts the mounting direction of the chip carrier portion 122 in the chip mounting portion 111, ensuring that the chip assembly 12 is accurately and stably mounted on the housing 11.

[0070] In other words, the first end 111b and / or the second end 111c are the limiting parts mentioned above, and the separating end 122b and / or the cutting end 122c are the mating parts mentioned above.

[0071] Furthermore, in this embodiment, by limiting the length of the separating end 122b of the chip carrier 122 to be less than the length of the cutting end 122c, the cutting end 122c can move along the second end 111c of the chip mounting part 111 to cooperate with the first end 111b, which plays a guiding role in the installation of the chip carrier 122 and facilitates operation.

[0072] Alternatively, the limiting part and the mating part can be other structures, as long as the chip carrier part 122 and the chip mounting part 111 are stably connected and the mounting direction of the chip carrier part 122 on the chip mounting part 111 can be distinguished. The specific configuration can be set according to the actual situation, and this embodiment does not limit it.

[0073] Please continue to refer to this. Figure 2 The cartridge body 11 has a bottom surface 112, a left side surface 113, and a right side surface 114. The bottom surface 112 extends along the length direction Y and the width direction X of the cartridge. The left side surface 113 and the right side surface 114 intersect with the bottom surface 112 and both extend along the length direction Y and the height direction Z of the cartridge. Specifically, the left side surface 113 and the right side surface 114 are arranged opposite each other and are roughly parallel to each other. Both the left side surface 113 and the right side surface 114 are roughly perpendicular to the bottom surface 112.

[0074] Please continue to refer to this. Figure 2 The chip mounting portion 111 is recessed in the bottom end face 112, and at least a portion of the chip mounting portion 111 can extend to penetrate the left side face 113 and / or the right side face 114.

[0075] Specifically, the chip mounting portion 111 is a groove formed on the bottom end surface 112, and one end of the chip mounting portion 111 can extend through the left side surface 113 along the width direction X of the ink cartridge.

[0076] Alternatively, the chip mounting portion 111 may be a groove formed on the bottom end face 112, and one end of the chip mounting portion 111 may extend through the right side face 114 along the width direction X of the ink cartridge.

[0077] Alternatively, the chip mounting portion 111 may be a groove formed on the bottom end face 112, with one end of the chip mounting portion 111 extending through the left side face 113 and the other end extending through the right side face 114 along the width direction X of the ink cartridge. The specific design can be adjusted according to actual conditions, and this embodiment does not impose any limitations.

[0078] Please continue to refer to this. Figure 2The cartridge body 11 has a bottom surface 112, a chip mounting portion 111 is recessed in the bottom surface 112, and an ink outlet 115 is opened on the bottom surface 112. The chip mounting portion 111 and the ink outlet 115 are distributed on the bottom surface 112 along the length Y direction of the ink cartridge, and there is a gap between them.

[0079] In this embodiment, the chip mounting part 111 and the ink outlet 115 are arranged adjacent to each other on the bottom surface 112, and there is a gap between them. When the chip assembly 12 is removed from the chip mounting part 111, or when the chip assembly 12 is installed on the chip mounting part 111, the debris generated during the disassembly and assembly process will not fall into the ink outlet 115, reducing the risk of the ink outlet 115 being contaminated.

[0080] Please continue to refer to the reference. Figure 1 , Figure 2 and Figure 3 The chip mounting portion 111 is a groove formed on the bottom end face 112. After the chip assembly 12 is mounted on the chip mounting portion 111, the surface of the chip assembly 12 facing away from the chip mounting portion 111 is flush with the bottom end face 112, which ensures the flatness of the bottom end face 112 and also reduces the risk of the chip assembly 12 colliding with other components after it protrudes from the bottom end face 112.

[0081] In some embodiments, the chip assembly 12 is bonded to the chip mounting portion 111, which facilitates operation, provides a strong connection, and makes it easy to disassemble the chip assembly 12.

[0082] Specifically, the chip assembly 12 is bonded and fixed to the chip mounting portion 111 using an adhesive. Specifically, the adhesive is first applied to the chip mounting portion 111, and then the chip assembly 12 is mounted onto the chip mounting portion 111, thereby bonding and fixing the chip assembly to the chip mounting portion 111.

[0083] Alternatively, the chip assembly 12 and the chip mounting portion 111 can be bonded and fixed together using adhesive tape. The adhesive tape can be double-sided tape.

[0084] Specifically, when installing the chip assembly 12 to the chip mounting part 111, one release paper of the double-sided adhesive can be peeled off first, and the double-sided adhesive can be adhered to the first mating surface 111a of the chip mounting part 111. Then, the other release paper of the double-sided adhesive can be peeled off, and the chip assembly 12 can be installed to the chip mounting part 111, so that the chip assembly 12 and the chip mounting part 111 are bonded and fixed.

[0085] Alternatively, one release paper of the double-sided adhesive can be peeled off first, and the double-sided adhesive can be adhered to the second mating surface 122a of the chip assembly 12. Then, the other release paper of the double-sided adhesive can be peeled off, and the chip assembly 12 can be installed into the chip mounting part 111, so that the chip assembly 12 and the chip mounting part 111 are bonded and fixed.

[0086] In some embodiments, the chip assembly 12 and the chip mounting part 111 may also be connected by a snap-fit ​​connection, etc., which can be set according to the actual situation. This embodiment does not limit it here.

[0087] Figure 6 This is a schematic diagram of the chip carrier 122. The chip carrier 122 is provided with a mounting groove 122d, and the chip body 121 can be detachably mounted in the mounting groove 122d.

[0088] The chip body 121 can be installed into the mounting slot 122d by adhesive bonding or snap-fitting, which can be set according to the actual situation. This embodiment does not limit it.

[0089] Please continue to refer to this. Figure 1 , Figure 3 The surface of the chip assembly 12 facing away from the bottom end face 112 of the chip is flush with the surface of the chip body 121 facing away from the chip support portion 122. That is, the surface of the chip body 121 facing away from the chip support portion 122 and the surface of the chip assembly 12 facing away from the bottom end face 112 of the chip are flush with the bottom end face 112. This ensures the flatness of the bottom end face 112 and also reduces the risk of the chip body 121 colliding with other components after it protrudes from the chip support portion 122.

[0090] In practical applications, ink cartridges can be used as standalone products. Alternatively, ink cartridges can be assembled with chip components to form ink cartridge assemblies for use together. The specific configuration can be determined according to the actual situation, and this embodiment does not impose any limitations on it.

[0091] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
