[0012] This application relates to the field of printing consumables technology, and more particularly to an ink cartridge. Background Technology

[0013] An image forming apparatus is a device that forms an image on a medium using imaging processing technology. It includes a printing unit and multiple ink cartridges, wherein the printing unit includes an imaging component, and the ink cartridges are typically inserted into the printing unit and can supply printing ink to the imaging component.

[0014] In related technologies, ink cartridges include an ink cartridge body and a chip. The chip is provided with a terminal group. The ink cartridge contacts the corresponding contact of the contact pin assembly of the printing device through the communication terminal in the terminal group to realize the electrical connection between the printing device and the ink cartridge. In addition, the chip is grounded by contacting the corresponding ground contact pin through the grounding terminal in the terminal group, thereby transmitting a grounding signal with the printing device to prevent excessive current from damaging the chip and the printing device.

[0015] However, the contact between the aforementioned grounding terminal and the grounding pin is unstable, resulting in situations where the chip cannot be grounded or the grounding is unstable. This affects the stability of the chip's grounding and its safety, and may also cause the printing device to fail to properly recognize the ink cartridge. Summary of the Invention

[0016] In view of the above problems, this application provides an ink cartridge that can improve chip grounding stability and usage safety.

[0017] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0018] This application provides an ink cartridge that is detachably installed in a printing device. The printing device has an assembly compartment and a mounting part and a grounding component disposed within the assembly compartment.

The ink cartridge includes an ink cartridge body, a chip, and a conductive component. The chip is disposed on the ink cartridge body, and at least a portion of the ink cartridge body and the chip can be located within the receiving cavity.

[0132] As described in the background section, image forming equipment includes an ink cartridge and a printing device. When the ink cartridge is inserted into the printing device, the chip in the ink cartridge may fail to ground or experience unstable grounding, affecting the chip's grounding stability and operational safety. The inventors have discovered that the cause of this problem is:

[0133] During ink cartridge installation, the printer's contact pin assembly is exposed within its mounting section. If the ink cartridge or a foreign object accidentally falls into the mounting section and impacts the grounding contact pin, the pin may become unexpectedly bent, its contact point may be damaged by friction, or its position may become unstable. This can prevent it from maintaining stable contact with the chip's grounding terminal, potentially causing the chip to fail to ground or have unstable grounding. Therefore, excessive current from the ink cartridge could damage the chip and the printer, and may also prevent the printer from properly recognizing the ink cartridge.

[0134] To address the aforementioned technical problems, the ink cartridge provided in this application includes a conductive component and a chip. The chip's ground terminal is electrically connected to the conductive component, and the chip is also electrically connected to a grounding component located in the assembly compartment of the printing device via the conductive component. This configuration ensures that when the ink cartridge is inserted into the printing device, the chip is electrically connected to the grounding component through its ground terminal and the conductive component, thereby ensuring stable grounding of the chip.

[0135] With this configuration, the ink cartridge in this embodiment connects the chip's grounding terminal to the grounding component through a conductive member. This avoids unstable contact between the grounding terminal and the grounding pin, which could lead to the chip being unable to ground or having unstable grounding. Therefore, it can improve the reliability of chip grounding, prevent excessive current from damaging the chip and printing device, improve the safety of ink cartridges and printing devices, and reduce the occurrence of printing devices being unable to recognize ink cartridges.

[0136] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0137] like Figures 1 to 3 As shown in the embodiment of this application, the ink cartridge 10 is one of the consumables of the printing device. The consumables include, but are not limited to, the ink cartridge 10. For example, the consumables can also be toner cartridges, ribbons, etc. This embodiment of the application uses the ink cartridge as an example for explanation.

[0138] When ink cartridge 10 is depleted, it needs to be replaced; therefore, ink cartridge 10 is typically detachable and installable into the printing device. For example, the printing device in this embodiment can be called a printer. The printer has an assembly compartment containing a mounting portion 90 for accommodating ink cartridges and a grounding component, wherein the grounding component is used to ground the printer (also called the printing device). The ink cartridge can be inserted into the mounting portion and electrically connected to the printer's mounting portion to establish communication between the ink cartridge and the printer.

[0139] Specifically, the printing device has an assembly chamber, within which a mounting section is disposed. The mounting section includes a receiving cavity and a stylus assembly, with a grounding component located outside the stylus assembly's position. The receiving cavity is used for inserting at least one ink cartridge, and at least a portion of the stylus assembly is exposed within the receiving cavity and electrically connected to the cartridge's chip. The grounding component and the stylus assembly are two distinct components; in other words, the grounding component is not part of the stylus assembly.

[0140] The ink cartridge is detachably installed in the printing device, which has an assembly compartment and a mounting part and a grounding component disposed in the assembly compartment. The mounting part includes a receiving cavity and a stylus assembly. The grounding component is located outside the location of the stylus assembly. The ink cartridge includes an ink cartridge body, a chip, and a conductive component. The chip is disposed on the ink cartridge body. At least a portion of the ink cartridge body and the chip can be located in the receiving cavity. The chip is provided with a communication terminal group and a grounding terminal. The communication terminal group is electrically connected to the stylus assembly. The conductive component is disposed in the assembly compartment and is configured to electrically connect the grounding terminal and the grounding component.

[0141] The stylus in the stylus assembly can deform, while the grounding component cannot. When the chip contacts the stylus, at least one stylus deforms; when the conductive component contacts the grounding component, the grounding component does not deform. It should be noted that since the contact surfaces of any two objects will deform when they come into contact, the "non-deformable" nature of the grounding component in this embodiment refers to the minute deformation that occurs when the grounding component contacts the conductive component, which is generally invisible to the naked eye, compared to the large deformation of the stylus.

[0142] The ink cartridge 10 includes an ink cartridge body 50, a chip 20, and conductive components. The ink cartridge body 50 is used to hold ink, and the chip 20 is disposed on the surface of the ink cartridge body 50. The chip 20 is used to store information such as the ink cartridge manufacturer, ink volume, ink cartridge type, and ink color. The chip has multiple terminals, which can be divided into communication terminals and ground terminals according to their purpose. That is, the chip has a communication terminal group and a ground terminal, and the communication terminal group includes multiple communication terminals.

[0143] Furthermore, the communication terminals are configured to contact and electrically connect with each pin of the contact pin assembly. The grounding terminal is connected to one end of the conductive member, and the other end of the conductive member can be connected to the grounding component, so that the chip's grounding signal can be transmitted to the grounding component through the conductive member, thereby completing the grounding.

[0144] When the ink cartridge 10 is inserted into the receiving cavity, each communication terminal of the chip 20 contacts and is electrically connected to the corresponding contact pin assembly, enabling data transmission, confirmation, and data interaction between the ink cartridge 10 and the printer. Simultaneously, the conductive component is electrically connected to the grounding component, ensuring that both the ink cartridge and the printer are grounded.

[0145] Compared with related technologies, and the scheme of electrically connecting the grounding terminal of chip 20 to the corresponding grounding contact in the contact assembly, the ink cartridge in this embodiment connects the grounding terminal of the chip to the grounding component through a conductive member. This avoids unstable contact between the grounding terminal and the grounding contact, which could lead to the chip being unable to ground or having unstable grounding. Therefore, it can improve the reliability of chip grounding, prevent excessive current from damaging the chip and printing device, improve the safety of chip and printing device use, and reduce the occurrence of the printing device being unable to recognize the ink cartridge.

[0146] Based on the above embodiments, in this application embodiment, the mounting part can be fixed in the assembly chamber, or the mounting part can be movably installed in the assembly chamber, for example, the mounting part can be slidably installed in the assembly chamber. However, since the arrangement of the mounting part in the assembly chamber is different, it affects the installation method between the ink cartridge and the mounting part, and consequently the arrangement of the chip on the ink cartridge and the electrical connection scheme between the conductive component and the grounding component are also different. This application will describe these differences with different embodiments.

[0147] Example 1:

[0148] In this embodiment, the mounting part is located inside the assembly chamber, and the grounding component is located inside the receiving cavity of the mounting part; specifically, the mounting part can be movably installed inside the assembly chamber.

[0149] In the first embodiment, an antenna-type conductive component is provided, and the metal part disposed in the assembly compartment is configured as a grounding component, that is, the metal part is grounded; one end of the conductive component is electrically connected to the grounding terminal of the chip 20, and the other end is connected to the grounding component, and the electrical connection point between the two is located above the chip.

[0150] Continue reading Figure 3 The mounting section is a component of the printing device, used to carry multiple or one ink cartridges. The ink cartridges are detachably installed into the mounting section along the mounting direction P. When the ink cartridges are used up, new ink cartridges need to be replaced.

[0151] The ink cartridge 10 includes a chip 20, a handle 30, an ink outlet 41, and an ink cartridge body 50. The mounting part 90 has a contact pin assembly 91, an ink supply part 92, an opening 95, and a bottom wall 90a. The ink cartridge 10 is installed into the mounting part 90 through the opening 95 along the mounting direction P (-Z axis direction). The handle 30 is used to fix the ink cartridge 10 to the mounting part 90 and prevent the ink cartridge 10 from detaching from the mounting part 90.

[0152] The cartridge 50 (also known as the ink cartridge body 50) stores ink. The ink reaches the ink supply unit 92 through the ink outlet 41, and then the ink supply unit 92 can supply the ink to the print head of the printer, so that the ink can be used to perform the printing action.

[0153] like Figure 4 As shown, the contact pin assembly 91 includes a contact pin 91a and a base 910, with the contact pin 91a disposed on the base 910. The chip 20 has a communication terminal group, which can be electrically connected to the contact pin of the contact pin assembly for mutual transmission of electrical signals.

[0154] In this embodiment, a three-dimensional Cartesian coordinate system, namely the XYZ axis coordinate system, is established. The three-dimensional Cartesian coordinate system of the ink cartridge is consistent with that of the mounting part. Taking the direction in which the ink cartridge 10 is installed onto the mounting part as the -Z axis direction, the direction in which the ink cartridge detaches from the mounting part is the +Z axis direction. The opening is located in the +Z axis direction, and the bottom wall 90a is located in the -Z axis direction. Under normal circumstances, the printer is placed flat on an office desk or printing table, with the opening 95 located at the top of the mounting part 90 and the bottom wall 90a located at the bottom of the mounting part 90. This arrangement facilitates the user's installation or removal of the ink cartridge.

[0155] Furthermore, the mounting section 90 can accommodate multiple or one ink cartridge, and the mounting section has multiple or one mounting position. For example, the mounting section 90 has four mounting positions, each of which can accommodate one ink cartridge, and the four ink cartridges can store four different colors of ink, such as black, yellow, blue, and red.

[0156] The mounting portion provided in this embodiment is an approximately cuboid or cube-shaped component with an opening. The inner sidewall and bottom wall 90a of the mounting portion constitute mounting positions. The stylus assembly 91 is mounted on the first sidewall 90c of the mounting portion. The mounting positions are arranged sequentially in the Y-axis direction, with four mounting positions arranged sequentially in the Y-axis direction. The direction perpendicular to both the Y and Z axes is the X-axis direction, where the direction from the inside of the mounting portion 90 towards the stylus assembly 91 is the +X-axis direction. The +X-axis is perpendicular to the first sidewall 90c. When viewed along the +X-axis direction, in the YZ plane, when the +Z-axis is above, the +Y-axis direction is on the left.

[0157] Continue reading Figure 4The contact pin assembly 91 includes: a base 910 and multiple contact pins mounted on the base 910. For example, the base 910 has five contact pins, namely the first contact pin 911 to the fifth contact pin 915. Each contact pin is a thin metal sheet that can conduct electricity and is not easily worn. Correspondingly, the base 910 has multiple slits 981-985 corresponding to the contact pins. Among them, slits 981, 982, 983, 984, and 985 correspond to contact pins 911, 912, 913, 914, and 915, respectively. The multiple slits 981-985 are all U-shaped and have slit openings in the +Z axis direction. The multiple contact pins 911-915 are installed into the slits 981-985 through the slit openings along the -Z axis direction.

[0158] Specifically, the first contact pin 911 is installed into the first slit 981 through the slit opening along the -Z axis direction; the installation method of the second contact pin 912 to the fifth contact pin 915 is the same, and will not be repeated here. One side of each of the first contact pins 911 to the fifth contact pin 915 is connected to the printer's main circuit through the internal circuit of the mounting part, and the other side is exposed in the receiving cavity of the mounting part 90, and can be electrically connected to each communication terminal of the chip 20 when the ink cartridge is inserted into the receiving cavity.

[0159] In this embodiment, the structures of the first contact pin 911 to the fifth contact pin 915 are identical. This embodiment uses the first contact pin 911 as an example to illustrate the structure of each contact pin. Figure 5 As shown, the first contact pin 911 is divided into a first part 911a, a second part 911b, and a third part 911c. The first part 911a is used to electrically connect with the communication terminal of the chip 20 and form a first contact portion; the second part 911b is connected to the internal circuit of the printer.

[0160] The third part 911c is connected to the first part 911a and the second part 911b. The third part 911c is located in the +Z axis direction of the first stylus 911. The first stylus 911 is fixed to the first slit 981 by the third part 911c or a part of the third part 911c (e.g., the horizontal part 911h of the third part 911c). The first part 911a and the second part 911b are located at the ends of the first stylus 911 in the -Z axis direction, so that the first part 911a and the second part 911b can be elastically deformed and easily return to their original shape after deformation. The first part 911a of the first stylus 911 is located in the -X axis direction, and the second part 911b is located in the +X axis direction. The first part 911a and the second part 911b protrude from the base 910, while the third part 911c does not protrude from the base 910.

[0161] Furthermore, the first portion 911a and the second portion 911b protrude from the base 910 in the X-axis direction, and the base 910 is located between the first portion 911a and the second portion 911b. The first portion 911a is closer to the mounting position than the second portion 911b, that is, the first portion 911a can be electrically connected to the chip 20.

[0162] The third part 911c includes a first vertical portion 911k and a second vertical portion 911j perpendicular to the X-axis direction, and a horizontal portion 911h parallel to the X-axis direction, wherein the horizontal portion 911h connects the first vertical portion 911k and the second vertical portion 911j. The first vertical portion 911k and the second vertical portion 911j extend vertically up and down along the Z-axis direction. The first vertical portion 911k is closer to the mounting position than the second vertical portion 911j. The end of the first vertical portion 911k connects to the first part 911a, and the end of the second vertical portion 911j connects to the second part 911b. The horizontal portion 911h or the first vertical portion 911k and the second vertical portion 911j are fixed to the first slit 981 in the +Z-axis direction.

[0163] Continue reading Figure 5 The first part 911a includes a first surface portion 911a1, a second surface portion 911a2, a third surface portion 911a3, and a fourth surface portion (not shown in the figure). The third surface portion 911a3 and the fourth surface portion are arranged opposite each other along the X direction. The area enclosed by the first surface portion 911a1 and the second surface portion 911a2 forms a ridge area. The first vertical portion 911k is the vertical area, while the second part 911b is another ridge area, and the second vertical portion 911j is another vertical area. The second stylus 912 to the fifth stylus 915 have the same arrangement and structure as the first stylus 911, and will not be described in detail here.

[0164] like Figure 6 and Figure 7 As shown, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and a plurality of terminals 130 (communication terminal groups). The substrate 120 has a front surface 120a, a rear surface 120b, a left side surface 120c, a right side surface 120d, a top surface 120e (not shown in the figure), and a bottom surface 120f.

[0165] The front surface 120a and the rear surface 120b are arranged opposite each other, with the front surface 120a located on the +X side of the rear surface 120b; the left side surface 120c and the right side surface 120d are arranged opposite each other, with the left side surface 120c located on the -Y axis side of the right side surface 120d; the top surface 120e and the bottom surface 120f are arranged opposite each other, with the top surface 120e located on the +Z axis side of the bottom surface 120f.

[0166] Furthermore, a plurality of terminals 130 are provided on the front surface 120a, so the front surface 120a is also called the first terminal surface. For example, a first terminal 131, a second terminal 132, a third terminal 133 and a fourth terminal 134 are provided on the front surface 120a. The positions of the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 on the Y-axis are all different. The positions of the first terminal 131 and the fourth terminal 134 on the Z-axis are the same. The positions of the second terminal 132 and the third terminal 133 on the Z-axis are the same, but the positions of the first terminal 131 and the third terminal 133 on the Z-axis are different.

[0167] Furthermore, the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 are all configured as communication terminals. The first terminal 131 (data terminal) is configured for transmitting or receiving data signals; the second terminal 132 (clock terminal) is configured for receiving clock signals; the third terminal 133 (power terminal) is configured for providing operating voltage to the memory 100; and the fourth terminal 134 (reset terminal) is used to reset the data inside the memory 100.

[0168] Each communication terminal has a contact portion C, which is represented by a circle. Multiple communication terminals have multiple contact portions C, which are designated as first contact portion C1 to fourth contact portion C4. Contact portion C is the most likely contact area of ​​the stylus on terminal 130 when the ink cartridge 10 is installed on the printer.

[0169] The communication terminal group includes a data terminal (first terminal 131), a reset terminal (fourth terminal 134), a power terminal (third terminal 133), and a clock terminal (second terminal 132). Along the mounting direction P of the ink cartridge 10 to the printing device, the contact portions C1-C4 of each terminal of the communication terminal group that contact the stylus assembly are arranged in two rows.

[0170] In the installation direction P (i.e., the Z-axis direction in the figure), the contact portion C1 of the data terminal and the contact portion C4 of the reset terminal are located on the upstream side; the contact portion C3 of the power supply terminal and the contact portion C2 of the clock terminal are located on the downstream side.

[0171] In this embodiment, the memory 100 and the aforementioned communication terminal are both disposed on the substrate 120. The memory 100 needs to be grounded and can be regarded as a "grounding terminal". The memory 100 needs to transmit and interact with the printing device to ensure that the ink cartridge is properly installed in the printing device and performs the corresponding tasks.

[0172] It should be noted that the memory 100 is used to store information such as manufacturer information, ink volume information, ink cartridge type information, and ink color. When the ink cartridge 10 is installed in the printer's mounting section, the memory 100 and the printer will perform data transmission, confirmation, and data interaction, which is achieved through the connection between the memory 100 and the printer's contact pins via communication terminals.

[0173] Furthermore, the memory 100 can be disposed on any one or several surfaces of the front surface 120a to the bottom surface 120f. Preferably, the memory 100 is disposed on the rear surface 120b. The specific shape and structure of the substrate 120 are not limited, and those skilled in the art can set it according to specific design requirements. For example, the chip 20 can be set as a rectangular structure, a chamfered rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure.

[0174] Furthermore, there is no limitation on the location of the memory 100 on the substrate 120. For example, the memory 100 can be located on the side of the chip 20 near the rear end of the direction -Z axis, or it can be located on the side of the chip 20 near the front end of the direction +Z axis, or it can be located in the middle of the chip 20. Those skilled in the art can set it according to specific design requirements, which will not be elaborated here.

[0175] Continue reading Figure 6 In this embodiment, the memory 100 is disposed on the rear surface 120b and near the right side surface 120d and the top surface 120e. The connector 135 (also referred to as a conductive member) is made of a conductive material with a certain hardness and is connected to the conductive sheet 135a (also referred to as a ground terminal) by solder. The conductive sheet 135a (also referred to as a ground terminal) is connected to the memory 100 through the circuit / conductive line built into the substrate 120, thereby connecting the connector 135 to the memory 100.

[0176] The conductive piece 135a (also known as the ground terminal) can be considered as part of the chip 20. Specifically, the conductive piece 135a (also known as the ground terminal) can be copper plating (achieved through electroplating) on ​​the chip 20, which can electrically connect the conductive member 135 and the memory 100. The connector 135 (also known as the conductive member) can be soldered, abutted, or otherwise contacted with the conductive piece 135a (also known as the ground terminal), as long as it can be electrically connected.

[0177] A connector 135 (also referred to as a conductive member) is disposed within the assembly compartment. The connector 135 is configured to electrically connect the conductive sheet 135a (also referred to as a grounding terminal) and the grounding component. Further, a grounding signal is transmitted between the ink cartridge 10 and the printing device via the grounding terminal 135a, the conductive member 135, and the grounding component. Optionally, a grounding signal is transmitted between the ink cartridge 10 and the printing device via an on-chip memory 100, the conductive member 135, and the grounding component. Further, a grounding signal is transmitted between the ink cartridge 10 and the printing device via an on-chip memory 100, the grounding terminal 135a, the conductive member 135, and the grounding component.

[0178] Since the connector 135 (also referred to as the conductive member) is electrically connected to the chip memory 100 and the ground terminal 135a, the connector 135 (also referred to as the conductive member) can also be regarded as the chip 20. That is, the chip 20 includes: memory 100, substrate 120, communication terminal group 130, conductive member 135, and ground terminal 135a.

[0179] The contact pins 911-914 in the contact pin assembly 91 can deform, while the grounding component cannot. When the chip 20 contacts the contact pins 911-914, at least one contact pin deforms. When the conductive member 105 contacts the grounding component, the grounding component does not deform; even minute deformations invisible to the naked eye are considered non-deformable. This structure helps ensure the stability of the electrical signals of the chip 20, especially the grounding signals.

[0180] It should be noted that the grounding signal is typically output by the main CPU of the printing device, and from the main CPU, it is output to the grounding contacts and grounding components of the contact assembly. When the ink cartridge is installed on the printing device, the grounding signal must be maintained between the ink cartridge and the printing device. In related technologies, the grounding signal is transmitted between the ink cartridge and the printing device sequentially through the grounding sub-terminal of the chip terminal group and the grounding contact.

[0181] However, in this application, the grounding signal is transmitted through a grounding terminal, a conductive component, and a grounding element. Optionally, this application transmits the grounding signal through an on-chip memory, a conductive component (also known as a connector), and a grounding element. Optionally, this application transmits the grounding signal through an on-chip memory, a grounding terminal, a conductive component (also known as a connector), and a grounding element, which can improve the stability of the grounding signal transmission.

[0182] This embodiment provides a detailed description of the layout of the communication terminal group and the grounding terminal on the chip substrate.

[0183] like Figure 7As shown, in this embodiment, the chip 20 includes a substrate 120, which includes a first surface 120a and a second surface 120b disposed opposite to each other. The first surface 120a is the front surface of the substrate 120, and the second surface 120b is the rear surface of the substrate. The first surface 120a is configured as the surface of the substrate close to the stylus assembly 91 of the printer. The first surface 120a is provided with a communication terminal group, which includes a plurality of communication terminals 131-134.

[0184] Furthermore, the chip also includes a ground terminal 135a, which is disposed on the first surface 120a or the second surface 120b, and is electrically connected to the conductive member 135 to form a grounding point of the chip.

[0185] In one embodiment, the first surface 120a has orthogonal first and second directions, and the first direction is configured as the mounting direction for mounting the ink cartridge 10 to the printing device. Each of the above-mentioned communication terminals has a first contact portion formed by contact with a stylus having a first projection relative to the first surface 120a, the first projections of a plurality of first contact portions on the first surface 120a forming a first region, and the grounding point formed by the conductive member and the grounding terminal having a second projection on the first surface 120a.

[0186] Along the second direction, at least a portion of the second projection lies outside the first region; in other words, along the second direction, a portion of the second projection lies within the first region, and at least a portion of the second projection lies outside the first region. For example, if a portion of the second projection lies outside the first region, in this case, along the second direction, the second projection is closer to the side of the first region, and the distance between the second projection and the first region is less than the length of the first region. Optionally, along the second direction, the second projection overlaps with the first region.

[0187] The chip 20 can also have the following variations, and different chip variations can be installed on the ink cartridge 10.

[0188] Example of a chip variation:

[0189] like Figures 8 to 10 As shown, the chip in this modified example differs from that in Embodiment 1 in that the chip 20 provided in this modified example has a memory 100, a substrate 120, and a terminal group (equivalent to the communication terminal group in Embodiment 1).

[0190] The memory 100 and the terminal group (equivalent to the communication terminal group in Embodiment 1) are disposed on the chip substrate 120. The memory 100 is used to store information such as manufacturer information, ink volume information, consumable cartridge type information, and ink color. When the consumable cartridge 10 is installed in the printer mounting section 90, data transmission, confirmation, and data interaction occur between the memory 100 and the printer, and this is achieved through the connection between the terminal group and the printer pins. Furthermore, the shape of each terminal in the terminal group can be other shapes, such as rectangles, squares, circles, trapezoids, or other irregular shapes.

[0191] In this modified example, a terminal group is provided on the front surface 120a, and the terminal group includes multiple terminals (131-139). Of course, the memory 100 can be disposed on any one or several surfaces from the front surface 120a to the bottom surface 120f, and the top surface 120e and the bottom surface 120f are arranged opposite each other in the Z-axis direction. The specific shape and structure of the chip 20 is not limited, and those skilled in the art can set it according to specific design requirements. For example, the chip 20 can be set as a rectangular structure, a chamfered rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure.

[0192] Furthermore, there is no limitation on the location of the memory 100. For example, the memory 100 can be located on the rear side of the chip 20 near the mounting direction, or it can be located on the front side of the chip 20 near the mounting direction, or it can be located in the middle of the chip 20. Those skilled in the art can set it according to specific design requirements, which will not be elaborated here.

[0193] In this embodiment, the terminal group includes 9 terminals, and the functions and roles of each terminal are as follows: First terminal 131; Second terminal 132 (reset terminal): used to reset the data inside the chip; Third terminal 133 (clock terminal): used to receive clock signals; Fourth terminal 134; Fifth terminal 135; Sixth terminal 136 (power terminal): used to receive a power potential different from the ground potential (e.g., 3.6V), and to provide power for the operation of the memory 100 through this terminal; Seventh terminals 137a, 137b, 137c, 137d (ground terminals): used to indirectly receive the ground potential; Eighth terminal 138 (data terminal): used to send or receive data signals; Ninth terminal 139.

[0194] In this embodiment, the third terminal group includes a first terminal 131 and a fourth terminal 134, and the second terminal group includes a fifth terminal 135 and a ninth terminal 139. Both the third and second terminal groups are installation detection terminals. The first terminal 131 and the fourth terminal 134 can also be short-circuit detection terminals, while the other terminals belong to the first terminal group. When the consumable cartridge 10 is installed on the printer, an electrical signal is transmitted between the installation detection terminals and the printer to detect whether the consumable cartridge 10 is installed. Furthermore, the fifth terminal 135 and the ninth terminal 139 are also called high-voltage terminals, used to receive the installation detection voltage (e.g., 42V) to complete the installation detection function of the consumable cartridge being installed on the mounting section.

[0195] For example, a high resistor (e.g., 62kΩ) is connected between the fifth terminal 135 and the ninth terminal 139. The change in current or voltage is detected to determine whether the consumable cartridge 10 has been installed in the mounting section. The first terminal 131 and the fourth terminal 134 are also called short-circuit detection terminals. The change in voltage on the terminals is detected to detect whether there is a short circuit on the chip 20. At the same time, the connection between the two terminals can be used to determine whether the consumable cartridge 10 has been installed on the printer.

[0196] In addition, the first terminal 131 and the fourth terminal 134 are also used to detect whether a short circuit has occurred between the terminals. Specifically, they are used to detect whether a short circuit has occurred between the fifth terminal 135 / ninth terminal 139 and the first terminal 131 / fourth terminal 134. When a short circuit occurs between the fifth terminal 135 / ninth terminal 139 and the first terminal 131 / fourth terminal 134, the printer can detect that the voltage on the first terminal 131 / fourth terminal 134 has increased, and the printer will then display a short circuit message, thus avoiding the risk of damage to the chip or the printer due to a short circuit.

[0197] Each terminal in the terminal group has its own contact portion, in Figure 8 The dots represent the contact points. The contact points are the most likely contact areas of the stylus on the terminals when the consumable cartridge 10 is installed on the printer. Viewed along a direction perpendicular to the mounting direction P, the arrangement is as follows: ground terminal (seventh terminal 137a, 137b, 137c, 137d), one second contact point, one third contact point, one first contact point, another third contact point, another second contact point, or the ground terminal and the fifth terminal 135 are aligned along the Z direction (e.g., ...). Figure 8 (As shown), of course, the grounding terminal can be located on the front surface 120a or the rear surface 120b of the chip. For example, the grounding terminal can be... Figure 8 , 9The four positions 137a, 137b, 137c, and 137d shown are arranged in this embodiment. Preferably, the grounding terminals 137a, 137b, 137c, and 137d are placed on the front surface 120a or the rear surface 120b. The arrangement is such that the grounding terminals are located in the +Z direction of the fifth terminal 135 or on the side of the +Z direction biased towards the -Y direction.

[0198] Optionally, along the Z-direction, the ground terminal (seventh terminal) is aligned with the first terminal 131. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131 and the fifth terminal 135. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fifth terminal 135. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134 and the ninth terminal 139. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134. Optionally, along the Z-direction, the ground terminal (seventh terminal) overlaps with at least a portion of the ninth terminal 139. The ground terminal (seventh terminal) is electrically connected to the memory 100 and the conductive member 140.

[0199] like Figure 11 As shown, in this embodiment, the memory 100 is disposed on the rear surface 120b. Near the right side 120d and top surface 120e of the rear surface 120b of the substrate 120, the connector 140 (equivalent to the conductive component in Embodiment 1, made of a conductive material with a certain hardness) is soldered / aggregated to the conductive sheet 140a (equivalent to the grounding terminal in Embodiment 1). The conductive sheet 140a is a contact pre-fabricated on the rear surface 120b of the substrate. This contact is connected to the memory 100 through a conductive line disposed inside the substrate 120, thereby realizing the electrical connection between the connector 140 and the memory 100.

[0200] Chip variation example 2:

[0201] The differences between this variant and the chip in Embodiment 1 are as follows: Figure 12 and Figure 13As shown, the terminal group 130 on the substrate includes four communication terminals, which are defined as the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134, respectively. The first terminal 131 (data terminal) is used to send or receive data signals; the second terminal 132 (clock terminal) is used to receive clock signals; the third terminal 133 (power terminal) is used to receive a power potential different from the ground potential (e.g., 3.6V / 3.3V), and provides power for the operation of the memory through this terminal; the fourth terminal 134 (reset terminal) is used to reset the data inside the chip or to adjust the processing device to a responsive state.

[0202] Each contact portion C1-C4 has a first projection on a first surface, wherein the first surface includes an orthogonal first direction and a second direction; wherein the first direction is configured as the mounting direction P of the ink cartridge to the printing device, in which case the first surface is parallel to the first direction (i.e., the mounting direction P); or, the first direction is configured as the extension direction of the projection line of the mounting direction P of the ink cartridge to the printing device on the first surface, and the first surface may be tilted relative to the first direction, i.e. the substrate is tilted on the ink cartridge body.

[0203] For example, in the attached figure, the first direction is the Z-axis direction, the X-axis direction is the second direction, and the second direction is perpendicular to the first direction. In this case, the first surface can be the front surface 120a or the rear surface 120b of the substrate.

[0204] The first projections of the aforementioned contact portions on the first surface form a first region M. For example, the substrate includes regions Q1 and Q2 arranged along the center line of the substrate, and the first region M is located within region Q1. The first terminal to the fourth terminal are all located within region Q1, and each formed contact portion is located within the first region M. Of course, the first region is also located within region Q1.

[0205] Furthermore, a grounding terminal is also provided on the rear surface of the substrate. This grounding terminal can be referred to as a fifth terminal / additional terminal. Grounding terminals 135a, 135b, 135c, and 135d (equivalent to the grounding terminals in Embodiment 1) are connected to the conductive component and the memory, and the grounding terminals are connected to the conductive component to form a grounding point. The grounding terminals can be arranged in four positions: 135a, 135b, 135c, and 135d.

[0206] For example, the first to fourth terminals are all located within region Q1. Furthermore, region Q2 can be eliminated or minimized to reduce the chip size and achieve miniaturization of the chip, ink cartridge, and printer. When region Q2 is eliminated or minimized, region Q1 refers to the chip region containing the first terminal 131 to the fourth terminal 134, and the contact portions of the first terminal 131 to the fourth terminal 134 are within the first region M.

[0207] The grounding terminals 135a, 135b, 135c, and 135d can be located in region Q1 on the rear surface 120b. For example... Figure 13 As shown, at the positions indicated by the first additional terminal 135a or the second additional terminal 135b, the second projection of the grounding point formed on the first surface is located within region Q1, and the second projection partially coincides with the first region M. Alternatively, the position of the fifth terminal 135 can be on region Q1 on the front surface 120a, for example, at the position indicated by the fourth additional terminal 135d. In this case, the second projection of the grounding point formed on the first surface is located within region Q1, that is, the second projection is located outside the first region M.

[0208] In other embodiments, the fifth terminal 135 may be located on the second region Q2 on the rear surface 120b. For example, Figure 13 At the position shown by the third additional terminal 135c, the grounding point formed in this case has its second projection on the first surface located outside the first region Q1, that is, the second projection is located outside the first region M. Further, in some embodiments, the width of region Q2 in the X-axis direction can be smaller than the width of region Q1 in the direction, and the distance between the side of the second projection closer to the first region M and the first region can be smaller than the length of the first region.

[0209] Chip Modification Example 3:

[0210] This variation example three is similar to the chip variation example one, except that: Figure 14 and Figure 64 As shown, in another embodiment, the front surface 120a of the substrate in this embodiment is provided with eight terminals. Seventh terminals 137a and 137b are provided on the rear surface 120b of the substrate 120 as ground terminals. The seventh terminals can also be disposed at other locations on the rear surface 120b for receiving ground potential. Furthermore, the seventh terminals only need to be disposed on the rear surface 120b; their number and shape are not limited. In this modified example, the chip 20 contains two generally rectangular seventh terminals.

[0211] The grounding terminal can be located within area Q1, such as... Figure 64 The location of grounding terminal 137a is shown; the grounding terminal can be located within area Q2, such as... Figure 64 The location of the grounding terminal 137b shown.

[0212] It should be noted that the contact pin assembly includes eight contact pins, each of which contacts a terminal on the front surface and forms its own contact portion. Figure 14 The contact area is indicated by a dot. The contact area is the most likely contact area of ​​the stator on the terminal when the ink cartridge 10 is installed on the printer.

[0213] like Figure 64 As shown, the first projections formed by each contact portion on the first surface enclose a first region M. A grounding point is formed by connecting the grounding terminal and the conductive member. The projection of the grounding point on the first surface is a second projection. When the grounding point is formed by grounding terminal 137a, the second projection is at least partially located within and at least partially located outside the first region M, meaning the second projection at least partially coincides with the first region M. Similarly, when the grounding point is formed by grounding terminal 137b, the second projection is at least partially located within and at least partially located outside the first region M, meaning the second projection at least partially coincides with the first region M.

[0214] like Figure 7 and Figure 15 As shown, the chip 20 has a positioning hole, and the ink cartridge body 50 is provided with a positioning post that cooperates with the positioning hole. When the positioning hole of the chip 20 is inserted into the positioning post, the chip 20 can be positioned. The chip 20 can be further fixed on the ink cartridge body 50 by welding.

[0215] Specifically, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120.

[0216] The first hole 121 is a rectangular recess formed by the top surface of the substrate and the bottom surface 120f. The second hole 122 is a through hole located on the 120a / 120b side of the substrate 120 near the bottom surface 120f. Correspondingly, the ink cartridge corresponding to the chip is provided with a chip mounting part, which includes a first positioning post 601 that mates with the first hole 121 and a second positioning post 602 that mates with the second hole 122. The first positioning post 601 and the second positioning post 602 are inserted into the first hole 121 and the second hole 122 respectively. Then, the chip 20 is fixed to the cartridge body 50 (also called the ink cartridge body 50) by welding with a hot soldering head. This arrangement can prevent the chip 20 from shifting its position during installation or use. Specifically, it can achieve positioning in three directions: X-axis, Y-axis, and Z-axis.

[0217] Understandably, the number of positioning holes is not limited here. Specifically, only one positioning hole can be provided (e.g., the first hole 121), or two or more positioning holes can be provided. Furthermore, the shape of the positioning holes is also not limited; they can be circular, square, or irregularly shaped. Similarly, the specific shape and number of the positioning posts and limiting parts are not subject to excessive restrictions here.

[0218] Based on the above embodiments, the ink cartridge body of this application embodiment is provided with a fixing component 603 on the -Y axis side of the handle 30. The fixing component 603 includes a first fixing member 603a, a second fixing member 603b, and a third fixing member 603c. The third fixing member 603c restricts the connector 135 (also referred to as a conductive member) to the ink cartridge body 50. The first fixing member 603a and the second fixing member 603b are arranged opposite to each other, which can clamp the connector 135 and bend the connector 135 at a right angle and in a direction away from the ink cartridge body 50.

[0219] This configuration secures the connector 135 (also known as the conductive component), preventing poor contact between the connector 135 and the printer's grounding component (not shown in the figure) due to swaying. Furthermore, the right-angle bend of the connector 135 facilitates its adjustment towards the printer's grounding component, ensuring easy electrical contact and preventing excessive current, thus reducing the probability of electric shock due to unstable grounding.

[0220] like Figure 16 As shown, during the insertion of the ink cartridge 10 with the chip 20 of this embodiment into the mounting section 90, the first terminal 131 to the fourth terminal 134 are electrically connected to the second surface portions 911a2 to 914a2 of the corresponding first portions 911a to 914a of the first contact pin 9111 to the fourth contact pin 914.

[0221] Continue reading Figure 1 and Figure 2 When the ink cartridge 10 is installed in the mounting section, one end of the connector 135 is connected to the grounding terminal provided on the rear surface 120b of the substrate, and the grounding terminal is electrically connected to the memory 100. The connector 135 extends from the rear surface 120b of the substrate and extends in the +Z axis direction close to the ink cartridge body 50. The first fixing member 603a and the second fixing member 603b act on the part of the connector 135 that is bent into a right angle, so that the connector 135 turns towards the metal part of the printer (also known as the grounding component). It should be noted that the metal part in the embodiment of this application can be part of the grounding component, or it is the grounding component. The metal part is provided in the assembly chamber of the printer, and the metal part (also known as the grounding component) is grounded, and there is a grounding signal transmission on the metal part.

[0222] Furthermore, the aforementioned connector 135 is electrically connected to the printer's grounding component and grounded through the grounding component. This configuration ensures that the electrical connection between the grounding component and the conductive member is located above the chip, resulting in good chip grounding stability, improved chip safety, and reduced likelihood of the printer failing to recognize the ink cartridge. The connector 135 (conductive member) is located at end 135e (e.g., Figure 15As shown, the connector 135 (conductive member) contacts and is electrically connected to the conductive wall plate 81. Specifically, the end 135e on the +X axis side of the connector 135 (conductive member) (as shown) Figure 15 (As shown) is in contact with and electrically connected to the conductive wall plate 81.

[0223] In this embodiment, the mounting part 90 is movably mounted inside the assembly chamber, and the grounding component is disposed outside the mounting part. A portion of the conductive component is disposed inside the receiving cavity of the mounting part and is electrically connected to the grounding terminal of the chip. The portion of the conductive component is disposed outside the mounting part and is used to electrically connect to the grounding component. That is, the grounding terminal of the ink cartridge chip is electrically connected to the grounding component through the conductive component to realize the transmission of the grounding signal.

[0224] Each chip can be adapted to ink cartridges with different embodiments and implementation methods.

[0225] Furthermore, since the mounting part is slidably mounted on the grounding rail, to ensure smooth sliding of the mounting part, in this embodiment, the contact position between the conductive component and the grounding component can be configured as a ball bearing or roller bearing. The ball bearing or roller bearing is part of the conductive component and is electrically connected to the conductive component. This arrangement reduces the friction between the contact position and the conductive component, ensuring smooth sliding of the mounting part and the ink cartridge on the grounding rail.

[0226] The conductive component can also be considered part of the chip. When the conductive component is considered part of the chip, the chip is detachably mounted in the printing device. The printing device has an assembly chamber and a mounting part and a grounding component disposed within the assembly chamber. The mounting part includes a receiving cavity and a stylus assembly. The grounding component is located outside the location of the stylus assembly. The chip has a communication terminal group, a conductive component (also called a connector), and a memory. The communication terminal group is electrically connected to the stylus assembly. The conductive component is electrically connected to the grounding component and the memory. The chip can also achieve the beneficial effects of this application.

[0227] It should be noted that the grounding component and the contact pin assembly are two different components. Furthermore, the chip is disposed on the ink cartridge body, and at least a portion of the ink cartridge body and the chip can be located within the receiving cavity, while the conductive component is disposed within the assembly compartment.

[0228] Second implementation method of Example 1:

[0229] The difference between the embodiments of this application and the aforementioned embodiments is as follows:

[0230] like Figures 17 to 20 As shown, the grounding component provided in this embodiment includes a grounding rail 80, and the grounding rail 80 is grounded. The grounding rail 80 is disposed in the assembly compartment, and the mounting part 90 is slidably disposed on the grounding rail 80. That is, the grounding rail 80 not only serves as a bearing component of the mounting part 90, but also serves as a grounding component to transmit grounding signals.

[0231] In one embodiment, a conductive wall plate 81 is provided on the side of the grounding rail 80 facing the mounting portion. The conductive wall plate 81 is connected to the grounding component, and the two can be an integral structure, which is not limited in this embodiment. The length extension direction of the conductive wall plate 81 is consistent with the extension direction of the grounding rail 80, and the conductive wall plate 81 intersects the horizontal plane. For example, the conductive wall plate 81 is perpendicular to the horizontal plane, or the conductive wall plate 81 is inclined relative to the horizontal plane.

[0232] Specifically, in this embodiment, the ink cartridge 10 also has a connector 135 (equivalent to a conductive component). The connector 135 is used to connect the chip 20 and other metal parts (equivalent to grounding components) on the printing device to realize the grounding function of the chip 20. That is, the connector 135 is configured as a conductive component. For example, the connector 135 includes a connecting body 135bb and a conductor 135cc, wherein the connecting body 135bb and the conductor 135cc can be integrally set or separately set. This embodiment does not limit this. The connector 135 can be a metal part such as copper, aluminum, or steel, or it can be a component made of conductive silicone, conductive plastic, etc.

[0233] The end of connector 135 near the chip is electrically connected to conductive sheet 135a (equivalent to a ground terminal). Conductive sheet 135a is disposed on substrate 120 and electrically connected to the memory of chip 20. The memory needs to be grounded, and the connection method between conductive sheet 135a and the memory is not limited. For example, conductive sheet 135a can be connected to the memory via a conductive wire, thereby connecting connector 135 to the memory. The position of conductive sheet 135a on substrate 120 is not limited. In this embodiment, conductive sheet 135a is disposed on the back surface 120b of the chip, located on a different surface from other terminals on chip 20. This ensures that conductive sheet 135a will not short-circuit with other terminals, guarantees good stability of chip grounding, and improves the safety of chip use. Conductive sheet 135a (equivalent to a ground terminal) is a copper-plated surface on chip 20 manufactured using processes such as electroplating.

[0234] Conductor 135cc is disposed on the ink cartridge body 50 and contacts other metal parts of the printer (equivalent to grounding components). Preferably, conductor 135cc is disposed inside the ink cartridge body 50 to prevent contact with external objects and damage to conductor 135cc, ensuring stable grounding function of connector 135. In this embodiment, conductor 135cc is disposed inside handle 30. Connecting body 135bb is used to connect conductive sheet 135a and conductor 135cc.

[0235] Specifically, the connecting body 135bb has a first part 135b1, a second part 135b2, and a connecting part 135b3. The first part 135b1 is used to connect with the conductive sheet 135a. The material of the first part 135b1 and the connection method with the conductive sheet 135a are not limited. For example, the first part 135b1 can be made of a conductive material with a certain hardness and can be connected to the conductive sheet 135a by soldering.

[0236] In some other embodiments, the connector 135 (equivalent to a conductive member) may not have a conductive sheet 135a, meaning the first part 135b1 is directly connected to the memory (not shown) of the chip 20. The connection method between the first part 135b1 and the memory is not limited; for example, the first part 135b1 can be directly connected to a conductive line connected to the memory via solder. The second part 135b2 is used to connect to the conductor 135cc. The connecting part 135b3 is used to connect the first part 135b1 and the second part 135b2. Preferably, the connecting part 135b3 is disposed in a corresponding groove on the cartridge body 50 to prevent external objects from damaging the connecting part 135b3 and affecting the conductivity of the connector 135, while also serving a fixing function.

[0237] like Figure 21 and Figure 22 As shown, in this embodiment, the conductor 135cc is disposed within the handle 30. The handle 30 has a main body 301, an extension 302, a limiting part 303, an engaging part 304, and a connecting part 305. The extension 302, the limiting part 303, the engaging part 304, and the connecting part 305 are respectively disposed on the main body 301, and their disposal on the main body 301 is not limited; for example, they can be detachable connections, fixed connections, etc.

[0238] One end of the extension 302 in the X-axis direction is connected to the main body 301, and the other end is in contact with other metal parts on the printer (equivalent to grounding components). In this embodiment, the other end of the extension 302 is in contact with the conductive wall plate 81 of the printer, so that the conductor 135cc is in contact with the conductive wall plate 81 to form an electrical connection. The extension 302 serves to protect the conductor 135cc from being damaged, broken, or displaced.

[0239] Compared with the contact area of ​​the chip grounding terminal on the contact pin inside the existing ink cartridge mounting section, the contact area of ​​the conductive wall plate 81 and the connector 135 in this embodiment is larger, which can ensure that the connector 135 and the grounding rail 80 are in stable and accurate electrical connection, ensure that the grounding function of the chip 20 is stably realized, prevent excessive current, and reduce the probability of electric shock hazard caused by unstable grounding.

[0240] Based on the above embodiments, the extension 302 in this application embodiment is further provided with a color recognition unit 302a for indicating the color of the ink stored in the ink cartridge. The ink color indication method of the color recognition unit 302a is not limited; for example, the ink color stored in the ink cartridge can be indicated by color, pattern, text, or combinations thereof.

[0241] The limiting part 303 cooperates with the limiting protrusion 502 provided on the ink cartridge to limit the movable range of the handle 30 in the X-axis direction. The position and shape of the limiting protrusion 502 on the ink cartridge body 50 are not limited. For example, the limiting protrusion 502 can be a cylinder, a cone, or an irregularly shaped protrusion. In this embodiment, the limiting protrusion 502 is a cylinder.

[0242] The engaging portion 304 engages with the fixing portion 90d provided on the mounting portion 90 to secure the ink cartridge 10 to the mounting portion 90, preventing the ink cartridge 10 from detaching from the mounting portion 90. The connecting portion 305 is used to connect the handle 30 to the ink cartridge body 50. The connection method between the connecting portion 305 and the ink cartridge body 50 is not limited; for example, it can be a detachable connection or a fixed connection. In some other embodiments, the handle 30 may not have the connecting portion 305, and the main body 301 may be directly connected to the ink cartridge body 50.

[0243] When the ink cartridge 10 is installed in the mounting section, one end of the connector 135 is a conductive piece 135a, which connects to the memory on the ink cartridge chip 20 and receives the current output by the chip 20. The conductive piece 135a transmits the received current to the conductor 135cc through the connecting body 135bb. The other end of the connector 135 is a conductor 135cc, which connects to other metal parts on the printer and transmits the current received from the connecting body 135bb to other metal parts on the printer, thus realizing the chip grounding function.

[0244] Specifically, conductor 135cc is disposed through the handle 30, and is disposed through the main body 301, extension 302, and connecting part 305 of the handle 30. Since the engaging part 304 on the main body 301 cooperates with the fixing part 90d on the mounting part 90 to fix the ink cartridge 10 to the mounting part 90, and conductor 135cc is disposed through the handle 30, its proximity to the engaging part 304 on the handle 30 ensures stable and accurate contact between the connector 135 and other metal parts on the printer, ensuring stable grounding of the chip 20, preventing excessive current, and reducing the probability of electric shock due to unstable grounding. Ensuring good chip grounding stability improves the safety of chip use and reduces the occurrence of situations where the printer cannot recognize the ink cartridge.

[0245] The third implementation method of Example 1:

[0246] Figures 23 to 26 This is a schematic diagram illustrating the third embodiment of Example 1 of this application. This embodiment differs from the second embodiment in the following ways: Figures 23 to 26 As shown, Figure 23 This is a schematic diagram of the ink cartridge 10 being installed on the mounting section 90. The grounding component has a grounding rail, and the grounding rail has a conductive wall plate 81. The conductive member 105 of the grounding rail is in contact with the conductive wall plate 81 and transmits a grounding signal. A baffle 84 is provided in the +Z axis direction of the conductive wall plate 81.

[0247] Normally, the baffle 84 is made of plastic and is non-conductive. In the X-axis direction, the end of the baffle 84 is closer to the mounting part 90 than the end of the conductive wall plate 81 (that is, the end of the baffle 841 is located on the +Z-axis and -X-axis side than the conductive wall plate 81). Therefore, when the ink cartridge 10 is installed into the printing device, the conductive member 105 needs to pass over the baffle 841 before it can come into contact with the conductive wall plate 81.

[0248] In this embodiment, one end of the conductive member 105 is connected to the ground terminal 135a on the chip 20, and the other end is in contact with the conductive wall plate 81 of the grounding component. The transmission path of the grounding signal is as follows: memory of the chip 20, ground terminal 135a, conductive member 105, and conductive wall plate 81 of the grounding component.

[0249] The handle 30 has: a main body 301, an extension 302, a locking part 304, a first gap 308, and a second gap 309. A fixing part 307 is also provided on the ink cartridge for fixing the conductive member 105. The extension 302 includes a flat extension 3025, a first bending part 3021, a second bending part 3022, an abutment receiving cavity 3023, and a fixing opening 3024. The purpose of providing the extension 302 is to: fix the conductive member 105, allow the conductive member 105 to pass over the baffle 84, and allow the conductive member 105 to abut against the conductive wall plate 81. The flat extension 3025 extends towards the +X axis direction to better facilitate the abutment between the conductive member 105 and the conductive wall plate 81.

[0250] The first bend 3021 extends from the flat extension 3025 and extends toward the +X axis (direction of the conductive wall plate 81) and the +Z axis (upward). The second bend 3022 extends from the first bend 3021 and extends toward the -X axis (direction away from the conductive wall plate 81 / direction toward the cartridge body) and the +Z axis (upward). This structural design is to guide the extension 302 and the conductive member 105 over the baffle 84 during the installation of the ink cartridge 10 into the printing device. When the ink cartridge 10 is removed from the printing device, the second bend 3022 can guide the deformation / compression of the handle 30, thereby facilitating the removal of the ink cartridge 10.

[0251] The abutment cavity 3023 is used to accommodate the abutment portion 1057 of the conductive member 105, which is used to abut the conductive member 105 against the conductive wall plate 81. The abutment cavity 3023 is a recess, which can protect the abutment portion 1057 to a certain extent and reduce the possibility of damage to it. The abutment cavity 3023 is located at the intersection of the first bend portion 3021 and the second bend portion 3022, so that the abutment portion 1057 is located at the position closest to the +X axis of the ink cartridge 10, so as to facilitate the abutment of the conductive member 105 against the conductive wall plate 81.

[0252] Furthermore, the fixing opening 3024 cooperates with the elastic part 1056 to securely fix the conductive member 105 to the ink cartridge 10, preventing the conductive member 105 from detaching from the ink cartridge 10. The handle 30 extends from the ink cartridge body 50 and has a certain degree of elasticity, allowing it to retract in the -X axis direction and return to its original position. The extension part 302 is located on the handle 30, and therefore also has a certain degree of elasticity, allowing it to move in the -X axis direction, enabling the conductive member 105 to pass over the baffle 84. When the handle 30 is compressed, it also tends to move in the +X axis direction, thus providing pressure to the abutment part 1057 and allowing it to better abut against the conductive wall plate 81. The abutment part 1057 is located at the intersection of the first bend 3021 and the second bend 3022.

[0253] The conductive member 105 includes a first part 1051a, a second part 1051b, and a third part 1051c. The first part 1051a is fixed to the ink cartridge body 50, specifically through the cooperation of the through hole 1053 and the fixing part 307, to prevent the conductive member 105 from detaching from the ink cartridge body 50. The through hole 1053 and the fixing part 307 can be fitted together in a tight-fitting manner.

[0254] Optionally, after the through hole 1053 mates with the fixing part 307, the portion of the through hole 1053 protruding from the fixing part 307 can be laid on the first part 1051a by welding and hot fusion to prevent the conductive member 105 from detaching from the cartridge body 50. The second part 1051b is adapted to the main body 301 of the handle 30, and a first gap 308 is provided on the -X axis direction side of the engaging part 304 and the +X axis direction side of the main body 301. The first gap 308 accommodates a portion of the second part 1051b. The third part 1051c fits the shape of the extension 302, allowing the conductive member 105 to better abut against the conductive wall plate 81.

[0255] The third part 1051c includes: an abutment portion 1057 and an elastic portion 1056. The abutment portion 1057 is disposed within the abutment receiving cavity 3023. The elastic portion 1056 is a sheet-like member that extends from the conductive member 105 and is elastic, and can cooperate with the fixing opening 3024 to fix the conductive member 105 to the handle 30. The conductive member 105 has a first bending region AA extending toward the conductive wall plate 41 and a second bending region BB connected to the first bending region AA and extending in the upward direction (+Z axis direction). The position where the conductive member 105 contacts the conductive wall plate 81 is located on the second bending region BB, that is, the abutment portion 1057 is located on the second bending region BB.

[0256] The first bending area AA is aligned with the first bending portion 3021 of the extension 302. The first bending area AA extends towards the +X axis (the direction where the conductive wall plate 81 is located) and the +Z axis (upward). The second bending area BB is the portion accommodated within the abutment cavity 3023. It is connected to the first bending area AA and extends upward (in the +Z axis direction). This structure facilitates the abutment between the conductive member 105 and the conductive wall plate 81. The abutment portion 1057 is a protrusion on the second bending area BB. The abutment portion 1057 can be an arc-shaped, spherical, linear, or dot-shaped protrusion. Preferably, the abutment portion 1057 is a spherical protrusion (e.g., ...). Figure 26 As shown, it facilitates contact with the conductive wall plate 81 and reduces the friction between the contact part 1057 and the conductive wall plate 81 as the ink cartridge 10 slides with the mounting part 90, ensuring smooth sliding of the ink cartridge 10.

[0257] Because the handle 30 is elastic, it can retract and return to its original state. The handle 30 is different in its natural state and in its state after being installed in the printing device. The conductive member 105 also has two states: an initial state and a contact state. The conductive member 105 can switch between the initial state and the contact state. In the initial state, the conductive member 105 is further away from the cartridge body 50 than in the contact state. In the initial state, the contact portion 1057 is further away from the cartridge body 50 than in the contact state. After the cartridge 10 is installed in the printing device, the contact portion 1057 of the conductive member 105 exerts pressure on the conductive wall plate 81, which allows the contact portion 1057 to better contact the conductive wall plate 81.

[0258] It should be noted that the conductive component 105 is made of a conductive material, such as metal, conductive silicone, or conductive plastic. Optionally, the conductive component 105 is made of metal and bent into the shape shown. Figures 23-25 The structure shown is as follows. The contact part 1057 can be made by hot pressing, which hot presses a spherical protrusion into the originally flat metal plate surface; the elastic part 1056 can be made by stamping, which breaks off one end of the elastic part 1056 to form a suspended elastic part 1056; the through hole 1053 can be made by stamping, which stamps a through hole.

[0259] Fourth implementation method of Example 1:

[0260] Figure 27 This is a schematic diagram of the fourth embodiment. The description of the ink cartridge in this embodiment is the same as that in Embodiment 1. The chip used is either Modified Example 1 or Modified Example 3 of the chip, which will not be described again here.

[0261] Example 2

[0262] It should be noted that the insertion method of the mounting part and the ink cartridge in this embodiment is different from that in Embodiment 1, and the structure of the mounting part of the printer is also different. In Embodiment 2, the mounting part 90 is fixed in the assembly chamber, and the grounding component is located in the receiving cavity.

[0263] The ink cartridge of Embodiment 2 is compatible with several ink cartridges in Embodiment 1. Embodiment 2 differs from Embodiment 1 in that it provides an antenna-type conductive member, and at least a portion of the cavity wall forming the mounting cavity is configured as a grounding component. One end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least a portion of the top wall of the mounting cavity, with the electrical connection point located above the chip.

[0264] Based on the above embodiments, the conductive sheet 135a in the conductive component can be omitted in this embodiment, the connector 135 can be directly connected to the conductive line by solder, and the position of the positioning hole set in the chip is also different from that in the first embodiment.

[0265] like Figures 28 to 31 As shown, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. Both the first hole 121 and the second hole 122 are through holes on the substrate 120, penetrating the front surface 120a and the rear surface 120b of the substrate 120. Specifically, the first hole 121 is a semi-circular recess formed from the left side surface 120c to the right side surface 120d, and the second hole 122 is a semi-circular recess formed from the right side surface 120d to the left side surface 120c.

[0266] Accordingly, the ink cartridge is provided with a chip mounting section, which includes a first positioning post 601 and a second positioning post 602. The first positioning post 601 and the second positioning post 602 are respectively engaged with the first hole 121 and the second hole 122 in a protruding manner. Then, the chip 20 is fixed to the ink cartridge body 50 by welding with a hot soldering head. This arrangement can prevent the chip 20 from shifting in position during the installation process or during use after installation.

[0267] like Figure 30 , Figure 31 As shown, when the consumable cartridge 10 is installed in the mounting section 90, one end of the connector 135 is connected to the grounding terminal 135a of the memory 100 / rear surface 120b provided on the rear surface 120b of the substrate. The connector 135 extends from the rear surface 120b of the substrate and fits against the cartridge body 50 (ink cartridge body 50) along the direction away from the chip 20 until it approaches the end of the connector 135. The connector 135 then bends away from the surface of the cartridge body 50, thereby connecting with the metal part 96 (equivalent to the grounding component in Embodiment 1) on the printing device. The beneficial effects of this design are: good stability of chip grounding and improved safety of chip use.

[0268] When the ink cartridge 10 is installed into the mounting section 90, the connector 135 connected to the memory 100 adheres to (or abuts against) the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10. Then, following the top surface of the ink cartridge 10, it extends from the top of the chip 20 and the top surface of the ink cartridge 10 and enters the gap of the mounting section. The end of the connector 135 is bent into a right angle. The end 135e of the connector 135 (the end away from the ink cartridge body) abuts against the metal part 96 (equivalent to the grounding part in Embodiment 1).

[0269] The connector 135 (same as the conductive member in Embodiment 1) bends away from the surface of the ink cartridge body 50 and toward the metal part 96 of the printer (the cavity housing the ink cartridge 10). This metal part 96 is the first sidewall 90c of the mounting portion in this embodiment, that is, the cavity wall that at least partially forms the housing cavity is configured as a grounding member, and the electrical connection position between the grounding member and the conductive member is located above the chip. This configuration provides good stability for chip grounding and improves the safety of chip use.

[0270] One end of the connector 135 is connected to the rear surface 120b of the substrate 120, and the other end is connected to the metal part 96 of the printing device. The metal part 96 of the printing device is not limited and can be any metal on the printing device that can be contacted by the connector 135.

[0271] Example 3:

[0272] It should be noted that the insertion method of the mounting part and the ink cartridge in this embodiment is different from that in Embodiment 1, and the structure of the printer's mounting part is also different. In Embodiment 2, the mounting part 90 is fixed in the assembly chamber, and the grounding component is located in the receiving cavity.

[0273] This embodiment provides another antenna-type conductive member, and at least a portion of the cavity wall forming the mounting cavity is configured as a grounding component. One end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least a portion of the cavity wall of the mounting cavity.

[0274] First implementation method of Example 3:

[0275] like Figure 32 As shown, the front surface 120a of the chip 20 is provided with a first terminal 131 to a fourth terminal 134. The arrangement of their respective contact portions C, memory 100, connector 135, and positioning hole 122 of the substrate are the same as in Embodiment 2, and will not be described again here.

[0276] The connector 135 (equivalent to the conductive member in Embodiment 1), which is connected to the memory 100, adheres to (or abuts against) the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10. Then, following the top surface of the ink cartridge 10, it extends from the top of the chip 20 and the top surface of the ink cartridge 10, entering the gap of the mounting portion. The end 135e of the connector 135 (the end away from the ink cartridge body) abuts against the grounding member. The extended portion of the connecting strip 135 (which can be called the connector 135) (equivalent to the conductive member in Embodiment 1) is bent away from the surface of the cartridge 50 and toward the metal part of the printing device (the cavity housing the ink cartridge 10) (equivalent to the grounding member in Embodiment 1), thereby achieving an electrical connection with the metal part of the printing device.

[0277] Second implementation method of Example 3:

[0278] In the second embodiment, another antenna-type conductive member is provided, and at least a portion of the cavity wall forming the mounting cavity is configured as a grounding component. One end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least a portion of the cavity wall of the mounting cavity.

[0279] In this embodiment, the insertion method of the mounting part and the ink cartridge is different from that in Embodiment 1, and the structure of the printer's mounting part is also different. Therefore, the direction represented by the three-dimensional coordinate system in this embodiment is also different from that in Embodiment 1. In Embodiment 2, the mounting part 90 is fixed in the assembly chamber, and the grounding component is disposed in the receiving cavity.

[0280] like Figure 33 As shown, the printer in this embodiment includes: a printing unit 4 and a base 5. The base 5 includes: a bracket and one or more mounting parts 90.

[0281] Furthermore, one mounting section 90 can hold one ink cartridge 10, when the number of mounting sections 90 is 4 (e.g. Figure 33 As shown), the four ink cartridges 10 can store four different colors of ink, such as black, yellow, blue, and red. Alternatively, when the base 5 can hold six ink cartridges 10, the number of mounting sections 90 is six, and the six ink cartridges 10 respectively store black, yellow, blue, red, light blue, and light red ink. Furthermore, multiple mounting sections 90 can hold ink of the same color (e.g., black).

[0282] Ink cartridge 10 is first installed into tray 97 along the first direction D1, and then the assembly of ink cartridge 10 and tray 97 is installed into mounting part 90 along the second direction D2. During printing, base 5 provides ink to printing unit 4, ensuring normal printing operation of printing unit 4. When the printer is in its natural position, printing unit 4 is directly above base 5.

[0283] Appendix Figure 33 The diagram shows a three-dimensional rectangular XYZ coordinate system, with the X, Y, and Z axes perpendicular to each other. When the printer is in its natural position, the direction of gravity is taken as the +Z direction, the installation direction D2 (second direction D2) where the ink cartridge 10 is installed into the mounting part 90 is taken as the +Y direction, and the arrangement direction of the mounting part 90 is taken as the +X direction. The first direction D1 is the +Z direction. When the ink cartridge 10 needs to be installed into the mounting part 90, the ink cartridge 10 is first installed onto the tray 97 along the first direction D1; then the assembly of the ink cartridge 10 and the tray 97 is installed into the mounting part 90 along the installation direction D2.

[0284] like Figure 34 As shown, this structure is the part installed in the +Y direction of the base 5. When the ink cartridge 10 (or an assembly) is installed into the mounting part 90 along the mounting direction D2, the front end side of the ink cartridge 10 in the +Y direction is... Figure 34 The structures shown are in contact, thereby ensuring that the ink cartridge 10 (or an assembly) is properly engaged with the mounting part 90.

[0285] The internal structure of the mounting section 90 includes a mounting bracket, on which a stylus assembly 91, an ink supply section 92 (ink filling tube), columnar positioning sections 93f and 93s, and a locking section 94 are mounted. The locking section 94 is a resettable swing rod-shaped component, that is, the locking section 94 is configured as the conductive swing rod of this application. The rod-shaped component has a protrusion extending along the Z-axis at its movable end. This protrusion is used to cooperate with the groove on the bottom of the tray 97 to fix the assembly consisting of the ink cartridge 10 and the tray 97.

[0286] The stylus assembly 91 can be electrically connected to the chip on the ink cartridge 10 when the assembly is mounted to the mounting part 90. The stylus assembly 91 includes multiple stylus pins (not shown in the figure) made of elastic conductive steel sheets. The stylus assembly 91 is inclinedly disposed in the mounting part 90. The specific structure of the stylus assembly 91 will not be described in detail, but its structure can be found in [reference needed]. Figure 4 Specifically, the above-mentioned assembly is installed or removed along the +Y and -Y directions in the figure. This assembly is physically engaged with the mounting part 90 through the housing and electrically connected to the stylus assembly 91 through the chip located on the ink cartridge.

[0287] like Figures 35-38 As shown, the ink cartridge 10 includes: a chip 20, a connector 60, an ink supply head 40, and an ink bag 10a. The chip 20 is located at the front end of the ink cartridge 10 in the installation direction D2. The connector 60 is configured as a conductive component. The connector 60 is made of conductive material, and one part of the connector 60 is connected to the chip 20, while the other part is connected to a grounding component.

[0288] The ink supply head 40 has an ink outlet 41 on the +Y axis side. The ink bag 10a stores ink. The ink outlet 41 is connected to the liquid inside the ink bag 10a. The ink reaches the ink filling tube 92 through the ink outlet 41. Then the ink filling tube 92 can supply ink to the print head, so that the print head can be used to perform printing.

[0289] By adopting the above technical solution, the grounding signal is transmitted to chip 20 through metal parts and conductive components, which improves stability and reduces the occurrence of grounding failures or unstable grounding. Grounding terminals are no longer placed on the substrate; instead, connectors are used to improve the grounding stability of the chip, prevent excessive current, and reduce the probability of electric shock caused by the grounding terminals on the chip potentially failing to make stable contact with the printer's stylus. This helps improve the safety of chip use and reduces the occurrence of printing devices failing to recognize ink cartridges.

[0290] In the above scheme, the metal part of the mounting part 90 (equivalent to the grounding component in Embodiment 1) can be the outer frame of the mounting part 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, and +Y axis directions) or a part of the outer frame. For user safety, all metal parts of the mounting part 90 are grounded, and the grounding signal between them and the printer is connected. Preferably, in this embodiment, another part of the connecting member 60 (equivalent to the conductive member in Embodiment 1) is connected to a part of the metal part 96 in the -Z axis direction of the mounting part 90, that is, at least part of the cavity wall of the receiving cavity forms a grounding component. Figure 33 As shown, the metal part 96 is disposed in the -Z axis direction of the base 5, and is connected to the grounding signal of the printer 1 along with the metal part 96 (equivalent to the grounding component in Embodiment 1).

[0291] like Figure 35 , Figure 36 As shown, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and multiple terminals 130. The substrate 120 has a front surface 120a, a rear surface 120b, a left side surface 120c, a right side surface 120d, a top surface 120e, and a bottom surface 120f. The front surface 120a and the rear surface 120b are disposed opposite to each other; the left side surface 120c and the right side surface 120d are disposed opposite to each other; and the top surface 120e and the bottom surface 120f are disposed opposite to each other.

[0292] Furthermore, the chip 20 has a first hole 121, a second hole 122, a third hole 123, and a fourth hole 124. The first hole 121, the second hole 122, the third hole 123, and the fourth hole 124 are all through holes on the substrate 120, and all penetrate the front surface 120a and the rear surface 120b of the substrate 120.

[0293] Specifically, the first hole 121 is a recessed portion formed from the top surface 120e to the bottom surface 120f, the second hole 122 is a recessed portion formed from the bottom surface 120f to the top surface 120e, the third hole 123 is a recessed portion formed from the left side surface 120c to the right side surface 120d, and the fourth hole 124 is a recessed portion formed from the right side surface 120d to the left side surface 120c.

[0294] With this configuration, the ink cartridge 10, on which the chip 20 of this embodiment is installed, is provided with a chip mounting part. The chip mounting part includes multiple positioning posts, which are respectively combined with the first hole 121, the second hole 122, the third hole 123 and the fourth hole 124 in a protruding manner. Then, the chip 20 is fixed to the ink supply head 40 by welding with a hot soldering head, so as to prevent the chip 20 from shifting its position along the Y-axis or Z-axis direction during the installation process or during use after installation.

[0295] Similar to the first embodiment described above, all terminals 131-134 on the front surface in this embodiment are communication terminals. The purpose of each communication terminal and its layout on the front surface are the same as in the first embodiment, and will not be repeated here.

[0296] The connector 60 (equivalent to the conductive member in Embodiment 1) and the memory 100 can also be connected via the fifth terminal / additional terminal 135a (equivalent to the grounding terminal in Embodiment 1) and its wires. It is understood that in this embodiment, the fifth terminal 135a may be omitted, and the connector 60 may be directly connected to the memory 100. Preferably, using the fifth terminal 135a makes the connection between the connector 60 and the memory 100 more effective and the contact more stable.

[0297] Furthermore, the conductive component and the fifth / additional terminal 135a can be connected by soldering or fixing. Each terminal 130 has a contact portion, which are designated as the first contact portion through the fourth contact portion. The contact portion is the most likely contact area of ​​the stator on the terminal 130 when the ink cartridge is installed on the printer.

[0298] In this embodiment, the connector 60 serves as a conductive component. The connector 60 is made of conductive material. The printer's grounding signal is connected to the memory through the conductive component and the fifth / additional terminal (equivalent to the grounding terminal), so that the ink cartridge chip and the grounding component are grounded together.

[0299] like Figures 37 to 42 As shown, the connector 60 includes a first part 60a and a second part 60b. The first part 60a is used to connect the second part 60b and the fifth terminal / additional terminal 135a of the chip 20; the second part 60b is used to connect the metal part 96 and the first part 60a.

[0300] Chip 20 is connected to the first part 60a. When the ink cartridge is installed on the mounting part 90, each communication terminal of chip 20 is connected to the first contact pin 911 to the fourth contact pin 914 on the contact pin assembly 52. ​​The shapes of the first part 60a and the second part 60b are not limited; they can be set to regular shapes, such as rectangles, or to be set to zigzag or other irregular shapes. In addition, the first part 60a can be integrally formed or can be set to be spliced ​​together from several metal pieces.

[0301] Furthermore, the connector 60 can also be a one-piece structure, without the first part 60a and the second part 60b. When the conductive member includes the first part 60a and the second part 60b, the structure of the first part 60a is simplified, and the second part 60b can be manufactured into a more complex structure.

[0302] For example, the second part 60b can also be used as a handle 30 for the ink cartridge, serving as a handle during the installation and removal of the ink cartridge from the tray 97, making it easier for the user to install and remove the ink cartridge. This design allows for the transmission of grounding signals while also simplifying the ink cartridge structure (reducing the production, manufacturing, and assembly of handle components). Therefore, this structure reduces the number of parts, simplifies some aspects of the ink cartridge structure, and lowers costs.

[0303] Furthermore, the first portion 60a of the connector 60 has a first connecting portion 60aa and a second connecting portion 60ab. The first connecting portion 60aa is used to connect to the fifth terminal or the additional terminal 135 of the chip 20; the second connecting portion 60ab is used to connect to the second portion 60b.

[0304] The second part 60b has: a first connecting part 60ba and a second connecting part 60bb. The second connecting part 60bb is used to connect with the second connecting part 60ab; the first connecting part 60ba is used to abut against the metal part 96.

[0305] Specifically, the first connecting portion 60ba abuts against the +Z axis surface of the metal part 96 to complete the transmission of the grounding signal. The first connecting portion 60ba is not necessarily at the end of the second part 60b; for example... Figures 41-42 As shown, the first connecting part 60ba is located at the middle of the second part 60b. The first connecting part 60ba can be composed of one or more locations combined.

[0306] like Figure 41 As shown, the first connecting portion 60ba can have three different positions. Because the second portion 60b, in addition to needing to abut against the metal part 96, also needs to function as a handle, in the Z-axis direction, the first connecting portion 60ba is located on the -Z-axis side of the second portion 60b. In the Z-axis direction, the first connecting portion 60ba is located on the -Z-axis side of the second connecting portion 60bb; the second portion 60b is located on the -Z-axis side of the first portion 60a; and the first portion 60a is located on the -Z-axis side of the chip 20. That is, the portion abutting against the metal part 96 is located at the uppermost position.

[0307] In the Y-axis direction, the first connecting portion 60ba is located on the -Y-axis side of the second connecting portion 60bb; the second portion 60b is located on the -Y-axis side of the first portion 60a; and the first portion 60a is located on the -Y-axis side of the chip 20. That is, the first connecting portion 60ba is located on the -Z-axis and -Y-axis sides of the second connecting portion 60bb; the second portion 60b is located on the -Z-axis and -Y-axis sides of the first portion 60a; and the first portion 60a is located on the -Z-axis and -Y-axis sides of the chip 20.

[0308] It should be noted that the metal part 96 contacted by the second part 60b can be any conductive metal part of the printer. Preferably, along the Z-axis, the metal part 96 contacted by the second part 60b is located at the top of the ink cartridge 10.

[0309] In addition, please continue to refer to Figure 34 , 37 When the ink cartridge is installed on the mounting part 90, the columnar positioning parts 53f and 53s cooperate with the positioning holes 97a and 97b on the tray 97 and the holes 42a and 42b on the ink cartridge to restrict the position of the assembly on the mounting part; the ink tube 92 (equivalent to the ink supply part 92 in Embodiment 1) matches the ink outlet 41 and can provide ink for printing; the stylus assembly 91 contacts the chip 20 and provides chip signal transmission.

[0310] The protrusion on the locking part 94 engages with the groove on the bottom of the tray 97 to secure the assembly consisting of the ink cartridge and the tray 97. The connector 60 contacts the metal part 96 to transmit a grounding signal. The connector 60 acts as a handle during the installation and removal of the ink cartridge from the tray 97, facilitating user operation.

[0311] It should be noted that the number and shape of the positioning holes 97a / 97b on the tray 97 and the holes 42a / 42b on the ink cartridge are not limited. For example, one or more positioning holes can be provided, and the shape can be set to round, square or other irregular shapes, as long as it can achieve stable cooperation with the printer and stable installation of the ink cartridge.

[0312] Further reading Figures 37 to 40 In this embodiment, the ink cartridge has an ink supply head 40 and an ink bag 10a containing ink. The chip 20 and the connector 60 are both disposed on the ink supply head 40. The ink supply head 40 has an ink outlet 41 on its +X side, which communicates with the ink bag 10a through an internal outlet channel, supplying the ink stored inside the ink bag 10a to the printer via the ink outlet 41.

[0313] See Figure 40 The ink supply head 40 has a shaft hole on its +Z axis side, and the shaft of the second part 60b is installed in conjunction with this shaft hole. A support member 102 is also provided on the +Z axis side of the ink supply head 40, which is located on the -Y axis side of the shaft hole on the +Z axis side of the second part 60b, and provides support for at least a portion of the second part 60b.

[0314] Specifically, in this embodiment, the support member 102 is a protrusion extending from the upper surface of the ink supply head 40 toward the +Z axis direction. Along the +Z axis direction, the support member 102 is higher than the aforementioned axis. In the ink cartridge installation state, at least a portion of the second part 60b contacts the support member 102 and is located on the +Z axis side of the support member 102.

[0315] Therefore, in the installed state, the second part 60b is tilted towards the -Y axis and -Z axis due to the support member 102, and the -Z axis end of the second part 60b contacts and electrically connects with the metal part 96 above the ink cartridge. Thus, the first connecting part 60ba is located on the -Z axis and -Y axis side of the second connecting part 60bb; and the second part 60b is located on the -Z axis and -Y axis side of the first part 60a.

[0316] This design not only reduces the risk of electric shock due to unstable grounding but also ensures stable chip grounding, improving chip safety. It also facilitates user operation when installing and removing ink cartridges.

[0317] It should be noted that the number and shape of the support members 102 are not limited. Specifically, the support members 102 can be one, two or more, and can be set as cuboids, cylinders or triangular prisms or other regular or irregular shapes, as long as they can support the second part 60b and enable it to make stable contact with the metal part 96.

[0318] Preferably, along the X-axis direction, compared to the right side 120d of the chip substrate 120, the contact area between the second portion 60b and the metal member 96 is closer to the left side 120c of the chip substrate 120. Preferably, the contact area between the second portion 60b and the metal member 96 may not be located as shown in the image. Figure 41 Instead of being located on the first connecting part 60ba, it can be set within the area of ​​the first region R1.

[0319] like Figure 41 As shown, the part of the second part 60b that connects to the metal part 96 is the third connecting part 60bc. The third connecting part 60bc is located at the first region R1, and in the X-axis direction, the second part 60b is inclined (this inclination can be achieved by the different heights of multiple support members 102), and the third connecting part 60bc is located at the +Z axis end of the second part.

[0320] It should be noted that during the process of installing the ink cartridge 10 into the printing device, the connector 60 (conductive component) contacts the grounding component first, and the chip 20 contacts the pin assembly 91 later.

[0321] The third implementation method of Example 3:

[0322] In the third embodiment, based on the second embodiment described above, a new conductive component is provided. One end of this conductive component is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least a portion of the cavity wall of the mounting cavity, with the two electrically connected at a position above the chip.

[0323] like Figure 43 and Figure 44 As shown, the chip provided in this embodiment differs from that in Embodiment 3 above in that the chip 20 has a recess 21. The function of the recess 21 is to avoid the fifth contact pin 915 and prevent the fifth contact pin 915 from abutting or contacting the chip 20; that is, when the ink cartridge 10 is installed on the mounting part of the printer, a part of the fifth contact pin 915 is located in the recess 21, and the fifth contact pin 915 will not abut or contact the chip 20.

[0324] It should be noted that the chip 20 may not have the recess 21. As long as the chip does not have a terminal / contact portion that can be connected to the fifth contact pin 915 in the X-axis direction, even if the chip 20 and the fifth contact pin 915 come into contact, no electrical connection will be generated between them, and no ground signal will be transmitted.

[0325] like Figures 45 to 51 As shown, the ink cartridge 10 includes: a chip 20, a connector 70 (equivalent to the conductive member in Embodiment 1), an ink supply head (also called a base) 40, and an ink bag 10a; the chip 20 is disposed on the front end side of the ink cartridge 10 in the mounting direction D2; the connector 70 is configured as a conductive member, and its material is conductive, wherein a portion of the connector 70 is connected to the chip 20, and another portion is connected to the metal part 96 of the mounting part 90 (equivalent to the grounding member in Embodiment 1). For example, the connector 70 is connected to the lower part 96a of the metal part 96 in the +Z axis direction, that is, the connector 70 is connected to the lower part 96a of the metal part 96 (equivalent to the grounding member in Embodiment 1) facing the mounting part 90.

[0326] The grounding signal between chip 20 and the printer is transmitted through connector 70 and metal component 96. By adopting the above technical solution, the grounding signal is transmitted to chip 20 via metal component 96 and connector 70, improving stability and reducing the occurrence of grounding failures or unstable grounding.

[0327] Furthermore, in this embodiment, the first terminal 131 to the fourth terminal 134 are disposed on the front surface 120a of the chip 20, and the fifth terminal 135 is disposed on the rear surface 120b of the chip 20. Multiple terminals 130 (first terminal 131 to fifth terminal 135) are disposed within a first region R1 on the -X axis of the chip 20. The first region R1 is located on the -X axis side of the chip, allowing the terminals on the chip 20 to be compactly arranged. The fifth terminal 135, which transmits the ground signal, and the communication terminals (first terminal 131 to fourth terminal 134), which transmit signals with a high level, are distributed on different surfaces of the chip 20, reducing the possibility of short circuits and avoiding mutual electromagnetic interference.

[0328] The difference from the third embodiment described above is that, for example... Figure 45 , Figure 46 As shown, the connector 70 provided in this embodiment is an integrally formed component. Its material can be a metal profile made of low-carbon steel or high-carbon steel, and for rust prevention, it can be nickel-plated or chromium-plated on the surface; its raw material can also be a metal profile made of stainless steel.

[0329] The cross-section of connector 70 can be circular, elliptical, rectangular, square, trapezoidal, etc. The manufacturing process can be hot forming or cold forming. For example, it can be manufactured by hot deformation of a 0.6mm diameter metal wire made of nickel-plated 82B high-carbon steel using a spring machine. Figure 45 The conductive component. This embodiment does not impose restrictions on the raw materials, profiles, or manufacturing processes of the conductive component, as long as it can ensure stable transmission of the grounding signal.

[0330] For example, if the profile cross-section is circular, it can be a metal wire with a diameter of 0.3-2.5 mm. Preferably, the diameter of the conductive component is a metal wire with a diameter of 0.5-1.0 mm, and the elasticity and shape stability of the metal wire are required. If the cross-sectional diameter of the metal wire is small, it may not be able to maintain its original shape stably, thus failing to meet the requirement that the ink cartridge 10 can maintain its original shape after being installed more than 10 times, thereby affecting the smooth transmission of the grounding signal. If the diameter of the metal wire is large, it may cause jamming during the installation or removal of the ink cartridge 10.

[0331] If the metal wire is not circular, a metal profile with a width between 0.3 and 2.5 mm can be selected, and preferably, a metal profile with a width between 0.5 and 1.0 mm can be selected for the conductive component. If the profile has a circular or elliptical diameter and a curved surface, a contact plane can be ground at position 704 in the fourth part (e.g., Figure 45(At the location of the dotted line) the portion connected to the lower part 96a of the +Z axis of the metal part 96 becomes the first contact part 70a.

[0332] The contact plane 70a' can be ground with the original first contact portion 70a as the center. Specifically, a small plane can be ground on a grinding machine (such as...). Figure 45 The portion that connects to the metal part 96 becomes the first contact portion 70a at the location indicated by the dotted line. Because the contact between the connector 70 and the metal part 96 is planar rather than point-contact, it reduces the impact of vibrations generated during printer operation and external vibrations on the contact stability between the connector 70 (equivalent to the conductive component in Embodiment 1) and the metal part 96, thus improving contact stability and facilitating stable transmission of the grounding signal. The contact plane 70a' can also be a small plane extruded from the original first contact portion 70a, referred to as the first contact portion 70a.

[0333] The connector 70 in this embodiment includes: a first contact portion 70a, a second contact portion 70b, a semi-closed ring 70c, a first bending space 70d, a second bending space 70e, a third bending space 70f, and a fourth bending space 70g. According to the bending condition of the profile, the connector 70 is sequentially divided into a first part 701, a second part 702, a third part 703, a fourth part 704, a fifth part 705, a sixth part 706, a seventh part 707, an eighth part 708, a ninth part 709, a tenth part 710, and an eleventh part 711.

[0334] The second part 702, the fourth part 704, the sixth part 706, the seventh part 707, the eighth part 708, and the tenth part 710 are bending areas. The first contact part 70a is located on the fourth part 704. Viewed in the Z-axis direction, the first contact part 70a is located at the end position of the connector 70 in the -Z direction, and abuts against the lower part 96a of the metal part 96 in the +Z axis direction. The first contact part 70a is located in the -Z axis direction of the second contact part 70b.

[0335] The fourth part 704 is located on the -Z axis side relative to the other parts of the connector 70. The semi-closed ring 70c is located on the -Y axis side of the connector 70, and the semi-closed ring 70c is a space formed by the first part 701, the second part 702, the third part 703, the fourth part 704, and the fifth part 705. The inclination directions of the third part 703 and the fifth part 705 are different; when viewed along the Y axis, the third part 703 is inclined towards the -Z axis direction, and the fifth part 705 is inclined towards the +Z axis direction.

[0336] That is, the third part 703 is inclined towards the +Y and -Z axes, and the fifth part 705 is inclined towards the +Y and +Z axes. The third part 703, the fourth part 704, and the fifth part 705 together form a mountain shape, with the fourth part 704 located on the -Z axis side. At least a portion of the fifth part 705 is located on the -Z axis side of the sixth part 706 to the eleventh part 711.

[0337] When the ink cartridge 10 is installed into the mounting section 90, the fifth part 705 will first contact the metal part 96 (if there is a mounting section protection component in the -Y axis direction of the metal part 96 in the printer, the fifth part 705 will first contact the mounting section protection component, and only after passing the mounting section protection component will the fifth part 705 contact the metal part 96). As the ink cartridge 10 is continuously installed along the installation direction D2, the -X axis side of the connecting component 70 and the semi-closed ring 70c will be compressed and deformed to a certain extent until the connecting component 70 is fully inserted into the mounting section 90. At this time, the first contact part 70a abuts against the lower part 96a of the metal part 96. In the above installation process, the fifth part 705 plays the role of guiding the connecting component 70 to be installed into the mounting section 90 and guiding the deformation of the connecting component 70, and finally completing the abutment between the first contact part 70a and the metal part 96.

[0338] When the ink cartridge 10 is about to detach from the mounting part 90, the first contact part 70a will not detach from the metal part 96 when the chip 20 detaches from the printer's stylus assembly 91. The first contact part 70a will detach from the metal part 96 only when the ink cartridge 10 is about to completely detach from the mounting part 90.

[0339] Furthermore, before the first contact portion 70a separates from the metal part 96, as the ink cartridge 10 moves out in the opposite direction to the installation direction D2, the third part 703 will play a guiding and buffering role, preventing the connector 70 from being stuck on the metal part 96 as the ink cartridge 10 separates from the mounting portion 90, and finally the ink cartridge 10 can be successfully removed.

[0340] With this configuration, when the ink cartridge 10 is detached from the mounting part 90, the connector 70 will return to its initial state under the action of its own elastic force. The connector 70 has an initial state (when the connector 70 has not yet been installed into the mounting part 90) and an abutting state (when the connector 70 is installed into the mounting part 90), which facilitates better contact between the connector 70 and the metal part 96 and reduces the occurrence of unstable contact.

[0341] Both the seventh part 707 and the eighth part 708 are bent into U-shaped structures with the opening facing the +Z axis direction. They can be joined with the first edge 403 and the second edge 404 on the ink supply head 40 to fix the conductive component. This allows the connector 70 to withstand the pressure of the metal part 96 on the -Y axis side of the conductive component 70 and the pressure of the chip 20 on the second contact part 70b. It also ensures the elastic recovery force of the connector 70 and allows the connector 70 to switch between the initial state and the contact state.

[0342] A third bending space 70f, with an opening facing the -Z axis, is formed between the seventh part 707 and the eighth part 708. Movable latches can be provided on the ink supply head 40, engaging with the third bending space 70f to prevent the connector 70 from detaching from the ink supply head 40.

[0343] The second contact portion 70b is formed on the tenth part 710. The second contact portion 70b abuts against the fifth terminal 135 of the chip 20, and the chip 20 applies a certain pressure to the second contact portion 70b, so that the second contact portion 70b makes better contact with the fifth terminal 135. The tenth part 710 can be ground into a small flat surface at the bent tip to form the second contact portion, thereby making the connector 70 and the chip 20 make more stable contact.

[0344] like Figures 43 to 46 As shown, the connector 70 has no offset position in the X-axis direction; that is, when viewing the cartridge 10 along the -Y-axis direction, the projection of the connector 70 lies on the same line perpendicular to the X-axis. Therefore, the projection of the first contact portion 70a on the chip 20 is located on the fifth terminal 135, the projection of the first contact portion 70a on the chip 20 is located within the first region R1, and the projection of the first contact portion 70a on the chip 20 is located on the -X-axis position side of the chip 20. The presence of the eleventh part 711 prevents the connector 70 from scratching the fifth terminal 135 during the manufacturing process, thus avoiding damage to the fifth terminal 135.

[0345] It should be noted that, as Figure 47 and Figure 48 As shown, the ink cartridge 10 also includes a chip mounting portion 201. The chip mounting portion 201 is used to support the chip 20. The chip 20 is fixed to the ink cartridge 10 by the chip mounting portion 201. The chip mounting portion 201 has: a through groove 2011, a receiving portion 2012, a flat surface 2013, a positioning post 2014, and a fixing portion 2015.

[0346] The plane 2013 abuts against the rear surface 120b of the chip 20 and is used to position the chip 20. The receiving portion 2012 is used to receive the memory 100. The positioning posts 2014 mate with the first to fourth holes of the chip 20, thereby ensuring that the chip 20 is fixed on the chip mounting portion 201. The connector 70 passes through the through slot 2011 and abuts against the fifth terminal 135 of the chip 20. Figure 31 As shown, all or at least a portion of the ninth part 709, the tenth part 710, and the eleventh part 711 of the connector 70 are accommodated within the through groove 2011.

[0347] The fixing part 2015 is a protrusion provided on the chip mounting part 201, which matches the fixing groove 451 on the ink supply head 40 and is used to fix the chip mounting part 201. Some clips can be provided on the fixing part 2015 and engage with the fixing groove 451 by the clips. This arrangement can reduce the chance of the chip mounting part 201 detaching from the ink supply head 40 under the elastic force of the connector 70.

[0348] The ink supply head 40 has an upper surface 40a on the -Z axis side, a protrusion, and a support portion 45. The protrusion is located on the -Y axis side of the upper surface 40a. The protrusion may only have a first protrusion 43 (e.g., Figure 50 As shown), it can also have a first protrusion 43 and a second protrusion 44 (as shown). Figure 50 (As shown). When the protrusion includes a first protrusion 43 and a second protrusion 44, the first protrusion 43 and the second protrusion 44 can serve as gripping parts for the user to install the ink cartridge 10 onto the tray 97 along the installation direction D1 or to remove the ink cartridge 10 in the direction opposite to the installation direction D1. By gripping the sides of the first protrusion 43 and the second protrusion 44, the user can move the ink cartridge 10, which is convenient for removing and installing the ink cartridge 10.

[0349] The ink supply head 40 also includes: a first protrusion 401, a second protrusion 402, a first ridge 403, a second ridge 404, and a fixing groove 451. The fixing groove 451 is used to fix the chip mounting part 201. When the connector 70 is installed on the ink supply head 40, the first protrusion 401 is located within the semi-closed ring 70c of the connector 70, reducing the occurrence of the connector 70 detaching from the ink supply head 40.

[0350] The second protrusion 402 is located within the first bending space 70d of the connector 70, reducing the possibility of the connector 70 detaching from the ink supply head 40. The first ridge 403 cooperates with the seventh part 707, and the two can be in an interference fit state, reducing the possibility of the connector 70 detaching from the ink supply head 40. The second ridge 404 cooperates with the eighth part 708, and the two can be in an interference fit state, reducing the possibility of the connector 70 detaching from the ink supply head 40. Some movable latches can be provided on the ink supply head 40. The movable latches engage with the third bending space 70f to prevent the connector 70 from detaching from the ink supply head 40.

[0351] The first protrusion 401 has a bevel 401a on its -Z axis side, the second protrusion 402 has a bevel 402a on its -Z axis side, the first ridge 403 has a bevel 403a on its -Z axis side, and the second ridge 404 has a bevel 404a on its -Z axis side. These bevels serve as guides when the connector 70 is installed onto the ink supply head 40.

[0352] Furthermore, such as Figure 52 As shown, in this embodiment, the ink supply head 40 of the ink cartridge 10 has widening members 46 on the +X axis side and the -X axis side, which increases the width of the ink cartridge 10 in the X-axis direction, which is beneficial to widening the ink bag 10a and increasing the ink capacity of the ink bag 10a. It is also understood that the tray 97 will also be widened in the X-axis direction. It should be noted that in this embodiment, during the installation of the ink cartridge 10 into the printing device, the connector 60 (conductive member) contacts the grounding component first, and the chip 20 contacts the contact pin assembly 91 subsequently.

[0353] Fourth implementation method of Example 3:

[0354] In the fourth embodiment, based on the above embodiments, a ground wire conductive member is provided, wherein one end of the conductive member is electrically connected to the ground terminal of the chip, the other end extends downward and is electrically connected to the conductive lever, and the electrical connection position of the two is located below the chip, and is further connected to the grounding component through the conductive lever.

[0355] Specifically, such as Figure 53 and Figure 54 As shown, the ink cartridge body 50 also includes a bottom shell 51 (equivalent to the ink supply head 40 in embodiments two and three). In the mounting direction D2 (+Y axis direction), at least a portion of the connector 70 is disposed on the front end side of the front surface 51a. A space Q is formed between the connector 70 (equivalent to the conductive member) and the front surface 51a. The space Q can accommodate a portion of the mounting part 90. At least a portion of the connector 70 is disposed below the bottom surface 51b of the ink cartridge 10.

[0356] Furthermore, such as Figure 55As shown, the connector 70 is configured as a first conductive sheet, and a conductive swing rod is provided at the bottom of the receiving cavity. The conductive swing rod is located at the bottom of the ink cartridge body and can limit the position of the ink cartridge body. In this embodiment, the locking part 94 is a resettable swing rod-shaped component, that is, the locking part 94 is configured as a conductive swing rod. The upper surface of the locking part 94 can be electrically connected to the first conductive sheet, and the electrical connection position is located below the chip.

[0357] After adopting the above technical solution, the space Q between the connector 70 and the front surface 51a is used to limit the mounting part 90, so that the connector 70 can contact the locking part 94 when the space Q and the mounting part 90 are properly matched. After the connector 70 contacts the locking part 94, the grounding signal of the chip 20 can be transmitted normally.

[0358] Furthermore, space Q can also accommodate a portion of connector 70. For example, one side of connector 70 may be shaped like an "n," and a portion of connector 70 may also be located within space Q. Figure 56 As shown, the connector 70 also includes an extension 710 disposed in the space Q, between the space Q and the front surface 51a. In this structure, the space Q is still disposed between the connector 70 and the front surface 51a. As long as a portion of the connector 70 conforms to this description, it is considered to meet the characteristic of forming a space Q between the connector 70 and the front surface 51a.

[0359] The space Q formed between the connector 70 and the front surface 51a can accommodate the front wall 97aa of the tray 97. The space Q and the front wall 97aa limit the movement of the conductive member itself, allowing it to contact the grounding component. Furthermore, the bottom of the receiving cavity has a bottom wall 97bb, and the grounding component can also be the bottom wall 97bb of the receiving cavity.

[0360] Continue reading Figures 53 to 56 As can be seen, part of the connector 70 is connected to the chip 20, and another part is connected to the grounding component of the mounting part 90. The connector 70 serves both as a mechanical means and a chip signal detection means to ensure that the ink cartridge is correctly installed on the printer's mounting part 90.

[0361] The space Q between the connector 70 and the front surface is used to mate with the front wall 97aa of the tray 97. Only when the front wall 97aa enters the space Q can the tray 97 be properly installed and positioned with the ink cartridge 10. When the assembly is installed into the mounting part 90, the connector 70 contacts the upper surface of the locking part 94 to complete the chip model detection and ensure that the ink cartridge 10 can pass the chip signal detection method. The combination of mechanical means and chip signal detection means more comprehensively ensures that the ink cartridge is correctly installed on the printer.

[0362] Furthermore, it should be noted that the ink cartridge 10 includes a chip 20, a bottom shell 51, an ink bag 10a, a connector 70, holes 220 and 210, a front surface 51a in the +Y axis direction, a bottom surface 51b in the +Z axis direction, and an ink outlet 41. The tray 97 has a front wall 97aa and positioning holes 971 and 972.

[0363] The locking part 94 has an upper surface 94a in the Z-axis direction. When the ink cartridge 10 is installed on the mounting part 90, the ink supply part 92 (ink tube) matches the ink outlet 41 to supply ink for printing. The printer's stylus assembly 91 contacts the communication terminal of the chip 20 to provide chip signal transmission.

[0364] The columnar positioning parts 93f and 93s cooperate with the positioning holes 971 and 972 on the tray 97 and the holes 220 and 210 on the ink cartridge to restrict the position of the assembly in the mounting part; the protrusion 941 on the locking part 94 is used to cooperate with the groove on the bottom of the tray 97 to fix the assembly composed of the ink cartridge 10 and the tray 97; the connector 70 cooperates with the front wall 97aa of the tray 97 and the connector 70 contacts the upper surface 94a of the locking part 94 to transmit a grounding signal.

[0365] Fifth implementation method of Example 3:

[0366] Based on the above embodiments, this embodiment provides another antenna-type conductive component, wherein the conductive component is composed of a conductive sheet and a conductive film of part of the ink bag, and the specific implementation is as follows:

[0367] The conductive component provided in this embodiment includes a first conductive sheet 71 and a first conductive transmission medium; the ink cartridge body includes an ink storage part, the ink storage part having an ink-containing cavity surrounded by a film layer structure; the film layer structure includes an insulating outer film, a conductive intermediate film and an insulating inner film stacked sequentially from the outside to the inside; the conductive intermediate film is configured as the first conductive transmission medium, and at least a portion of the conductive intermediate film is used to electrically connect the first conductive sheet to the top wall of the receiving cavity.

[0368] For example, such as Figure 57 and Figure 58 As shown, the ink cartridge in this embodiment includes an ink storage section disposed within the ink cartridge body. The ink storage section is configured as an ink bag 10a. The ink bag 10a has an ink-containing cavity surrounded by a membrane structure, and the ink-containing cavity is used to store ink.

[0369] For example, an ink bag has an upper surface and a lower surface, which are the outer surfaces of a membrane structure. The membrane structure includes an insulating outer membrane, a conductive intermediate membrane, and an insulating inner membrane arranged sequentially from the outside in. The insulating outer membrane forms the outer surface of the ink bag, including the aforementioned upper and lower surfaces. The insulating inner membrane forms the inner surface of the ink bag and is in contact with the ink. The conductive intermediate membrane is disposed between the insulating outer membrane and the insulating inner membrane, and at least a portion of the conductive intermediate membrane can serve as the aforementioned first conductive transmission medium, thus being considered part of a conductive component. Furthermore, a portion of the conductive intermediate membrane can be electrically connected to a grounding component.

[0370] In this embodiment, a portion of the conductive intermediate film is exposed on the outer surface of the film structure, forming a first electrical connection portion. The first electrical connection portion can be electrically connected to the first conductive sheet, and the other end of the first conductive sheet is electrically connected to the ground terminal of the chip. For example, the insulating outer film includes a first cutout portion, which is disposed close to the first conductive sheet, and a portion of the conductive intermediate film is exposed on the first cutout portion, forming the first electrical connection portion.

[0371] A portion of the conductive intermediate film is exposed on the outer surface of the film structure, forming a second electrical connection portion. The second electrical connection portion is opposite to the first electrical connection portion and is electrically connected through the unexposed conductive intermediate film between them. The second electrical connection portion is electrically connected to the grounding component.

[0372] For example, the insulating outer film includes a second perforated portion, with at least a portion of the conductive intermediate film exposed within the second perforated portion, forming a second electrical connection portion. This second electrical connection portion is electrically connected to the first electrical connection portion via the partially conductive intermediate film to transmit a grounding signal. That is, the grounding signal between the chip and the printer is transmitted through the first conductive sheet, the intermediate conductive film, and the grounding component. This configuration improves the grounding stability of the ink cartridge and reduces situations where grounding is impossible or unstable.

[0373] Based on the above embodiments, in this embodiment, the grounding component can be the outer frame of the mounting part 90 (the outer frame in the directions of +Z axis, -Z axis, +X axis, -X axis, and +Y axis) or a part of the outer frame. For example, the cavity wall forming the receiving cavity can be used as the grounding component. The first electrical connection part is located on one side of the Y axis of the ink bag 10a, and the second electrical connection part is located on one side of the -Y axis of the ink bag. The second electrical connection part is located on the -Z axis side of the first electrical connection part, that is, the second electrical connection part is closer to the cavity wall of the receiving cavity than the first electrical connection part.

[0374] It should be noted that the film structure of a local area on the surface of the ink bag 10a has four layers: along the direction from the outside to the inside of the ink bag 10a, the first layer is made of PET material, so the first layer is also called PET film, i.e., the insulating outer film; the second layer is made of Al material and is conductive, also known as aluminum film, metal film or intermediate conductive film 10a1; the third layer is nylon film; the fourth layer is made of PET140 material, so the fourth layer is also called PET140 film.

[0375] Other areas on the surface of the ink bag 10a have only three layers of film. These areas are exposed on the outer surface of the film structure. Along the direction from the outside of the ink bag 10a towards the inside, these layers are, in sequence, the aforementioned conductive film 10a1, the nylon film, and the PET 140 film. Since the conductive film 10a1 is located on the outermost side in these areas, they are also called the conductive areas of the ink bag 10a; in other words, these conductive areas form electrical connections. The conductive films 10a1 in all areas of the ink bag 10a are connected. That is, whether the ink bag 10a has three layers or four layers, it has the same conductive film 10a1. Furthermore, the conductive film 10a1 is isolated from the ink stored in the ink bag 10a; therefore, in this design, the ink does not participate in the transmission of grounding signals.

[0376] In this embodiment, a portion of the first conductive sheet 71 is connected to the chip 20, and another portion is connected to the conductive film (first electrical connection portion) of the conductive region A of the ink bag 10a. The first conductive sheet 71 has a first portion 71a and a second portion 71b. The first portion 71a is connected to the chip 20, and the second portion 71b is connected to the conductive film.

[0377] After the conductive film in conductive region A is connected to the first conductive sheet 71, a PET film is used to cover the -Z axis side of the connection between the two to make the ink cartridge 10 more aesthetically pleasing. Alternatively, an adhesive (such as tape) can be used to fix the connection between the two to make the connection between the first conductive sheet 71 and the first electrical connection part more stable.

[0378] like Figure 59 As shown, in this embodiment, the -Y axis side end of the ink bag 40 extends towards the -Z axis direction. The -Z axis side surface of this end has a conductive region B, which is a second electrical connection part. The conductive film 10a1 of the conductive region B is connected to the metal part 96 of the +Z axis side outer frame of the mounting part 90, and the metal part 96 is the cavity wall forming the receiving cavity, thereby realizing the transmission of the grounding signal between the chip 20 and the printer 1.

[0379] It should be noted that a conductive area can be provided at any point on the ink bag 10a, and the conductive film in that area can be connected to the metal part 96 of the mounting part 90. For example, except for the -Y axis end of the ink bag 10a, the conductive film at the +Y axis, +X axis, -X axis, -Z axis, or +Z axis position of the ink bag 10a can all be connected to the metal part 96 of the mounting part 90.

[0380] like Figure 60 and Figure 61 As shown, based on the above embodiments, the ink cartridge provided in this application embodiment further includes a second conductive sheet 72. The second conductive sheet 72 and the first conductive sheet 71 are spaced apart, and the second conductive sheet 72 has a first part 72a and a second part 72b. The first part 72a is connected to the conductive film on the conductive area C of the ink bag 10a, and the second part 72b is connected to the metal part 96 of the mounting part 90. The grounding signal is transmitted to the chip 20 through the metal part 96, the second conductive sheet 72, the conductive film, and the first conductive sheet 71. The Y-axis side end of the ink bag 40 does not directly contact the metal part of the mounting part 90.

[0381] Optionally, after the conductive film in the conductive region C is connected to the second conductive sheet 72, a PET film is used to cover the -Z axis side of the connection between the two to make the ink cartridge 10 more aesthetically pleasing, or an adhesive (such as tape) is used to fix the connection between the two to make the connection between the second conductive sheet 72 and the conductive film 10a1 more stable.

[0382] In the above scheme, the metal parts of the mounting section 90 can be the outer frame of the mounting section 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, and +Y axis directions) or a part of the outer frame. For user safety, all metal parts of the mounting section 90 are grounded, and their grounding signals are connected to the printer.

[0383] In this embodiment, the second conductive sheet 72 extends from the conductive area C of the ink bag 10a first in the -Z axis direction, then in the -X axis side or +X axis side until it crosses the tray 97, and then in the +Z axis direction and connects to the outer frame of the mounting part 90 on the +Z axis side.

[0384] It should be noted that the number of the second conductive sheet 72 is not limited; for example, one or more can be provided. Furthermore, its position on the ink bag 10a is also not limited; for example, it can be located on the upper or lower surface of the ink bag 10a, or on the +X-axis side, -X-axis side, +Y-axis side, or -Y-axis side of the ink bag 10a.

[0387] Figure 63 This is a schematic diagram of the ink cartridge according to the seventh embodiment of Embodiment 3 of this application. The description of this embodiment of the ink cartridge is consistent with the first to third embodiments of Embodiment 3. The chip used is either Modified Example 1 or Modified Example 3 of the chip, which will not be repeated here.

[0388] Example 4:

[0389] Based on the above-described embodiment 1, this embodiment further includes a conductive support plate 82, with the mounting portion 90 slidably disposed on the guide rail 86; a barrier plate 85 is provided between the guide rail 86 and the conductive support plate 82 support; the conductive support plate 82 is disposed on the side of the barrier plate 85 away from the mounting portion, and the length direction of the conductive support plate 82 is consistent with the extension direction of the grounding guide rail 80, for example, the conductive support plate 82 is disposed parallel to the horizontal plane, and the conductive support plate 82 and the conductive wall plate 81 are arranged opposite to each other on both sides of the grounding guide rail 80. Accordingly, the conductive member includes a bridging portion, so that the conductive member passes over the barrier plate 85, that is, the bridging portion is disposed above the barrier plate 85, and the portion of the bridging portion near the conductive support plate can contact and be electrically connected to the conductive support plate.

[0390] like Figure 66 As shown, the guide rail 86 may be a conductive component carrying a grounding signal, or it may be a non-conductive component not carrying a grounding signal. When the guide rail 86 carries a grounding signal, its conductive support plate 82 may be part of the guide rail, or the guide rail 86 and the conductive support plate 82 may be two different components. The barrier plate 85 is a non-conductive component not carrying a grounding signal (for example, the barrier plate 85 is made of non-conductive plastic). Therefore, in this embodiment, the conductive component must cross the barrier plate 85 to abut against the conductive support plate 82 to achieve the beneficial effects of this application.

[0391] Specifically, such as Figure 64 and Figure 65 As shown, in this embodiment, the chip 20 is disposed on the front end side of the ink cartridge 10 in the mounting direction, and the memory 100 is disposed on the rear surface 120b of the chip 20. A conductive sheet 140a is also provided between the chip 20 and the ink cartridge 10. The shape of the conductive sheet 140a is approximately the same as that of the chip 20. An opening 111 with the same shape as the memory 100 is provided in the middle of the conductive sheet 140a. The size of the opening 111 is just enough to accommodate the protruding part of the memory 100. The grounding terminals 137a and 137b are attached and connected after the chip 20 and the conductive sheet 140a are installed.

[0392] The connector 140 is configured as a conductive component. The connector 140 (equivalent to a conductive component) is made of a conductive material with a certain degree of hardness. One end of the connector 140 (equivalent to a conductive component) is connected to the conductive sheet 140a via solder. Of course, the connector 140 and the conductive sheet 140a can be a single, integrally formed sheet metal part, or they can be a structure composed of multiple connected parts. Optionally, in this embodiment, the conductive sheet 140a may not be present, and the connector 140 (equivalent to a conductive component) can be directly connected to the grounding terminal to achieve the function of transmitting a grounding signal.

[0393] like Figures 66 to 70 As shown, the other end of the connector 140 can extend along the first sidewall 50a of the ink cartridge body 50 in the -Y axis direction, or along the second sidewall of the ink cartridge body in the +Y direction (opposite to the first sidewall 50a, not shown in the figure), or along the top wall 50d of the cartridge body in the +Z direction, towards the rear sidewall of the cartridge 10, until it reaches the end near the connector 140. The connector 140 is bent away from the surface of the ink cartridge 10 to form a bridging portion 140b, and is connected to the conductive support plate 82 of the grounding rail. Further, the grounding signal between the chip 20 and the printer is transmitted through the conductive sheet 140a, the connector 140, and the conductive support plate 82.

[0394] It should be noted that the guide rail 86 is a component used to support the mounting section 90. For user safety, the grounding signals between the guide rail 86 and the printing device are connected. The conductive support plate 82 is a metal component in the printing device. For user safety, the grounding signals between the conductive support plate 82 and the printing device are connected. With this configuration and the above technical solution, the grounding signal is transmitted to the chip 20 through the conductive support plate 82 and the connector 140, improving stability and reducing the occurrence of grounding failures or unstable grounding, thus achieving the beneficial effects of this application.

[0395] Based on the above embodiments, in this application embodiment, the end of the conductive member near the grounding component is provided with an abutment portion, which is configured to contact the conductive support plate 82 so that the conductive member is electrically connected to the conductive support plate 82 and the conductive wall panel.

[0396] Furthermore, since the mounting part is slidably mounted on the guide rail, to ensure smooth sliding of the mounting part, the abutment part in this embodiment can be configured as a ball bearing or roller bearing. The ball bearing or roller bearing serves as part of the conductive component and is electrically connected to the conductive component. This arrangement reduces the friction between the abutment part and the conductive support plate or conductive wall plate, ensuring smooth sliding of the mounting part and the ink cartridge 10 on the grounding guide rail.

[0397] In another embodiment, the conductive component includes not only the second conductive sheet, but also the second conductive transmission medium electrically connected to the second conductive sheet, and the carrier electrically connected to the second conductive transmission medium. That is, in this embodiment, the conductive component is composed of the conductive sheet, the conductive transmission medium, and the carrier.

[0398] Furthermore, the carrier is positioned close to the chip, specifically at the end of the cartridge body furthest from the guide rail. One end of the carrier is connected to the ground terminal of the chip, and the other end extends into the ink-containing cavity of the cartridge body, where it is electrically connected to the printing liquid medium, such as ink. The ink acts as a conductive medium connected to the carrier, allowing the grounding signal from the ground terminal to be transmitted to the ink via the carrier.

[0399] Furthermore, one end of the second conductive sheet extends into the ink cavity and can contact the ink, while the other end of the second conductive sheet forms a bridging portion and is positioned above the barrier plate 85 through the bridging portion. The bridging portion can be electrically connected to the conductive support plate, thereby transmitting the grounding signal from the ink through the second conductive sheet to the conductive support plate.

[0400] For example, such as Figure 71 As shown, the connector 140 is configured as the second conductive sheet mentioned above. As part of the conductive component, it is made of a conductive material with a certain hardness. The connector 140 can be an integrally formed sheet metal part or a structure composed of multiple connected parts. This application embodiment does not limit this.

[0401] The connector 140 also includes a fixing member 141. The fixing member 141 can be made of silicone material. The middle part of the fixing member 141 has a through hole that can accommodate the bent part 1402 of the connector 140. The connector 140 is installed as follows: first, the fixing member 141 is inserted into the connector 140, then the vertical part 1401 of the connector 140 with the fixing member 141 is inserted into the through hole at the upper part of the rear side wall 50b of the ink cartridge 10, and then the position of the fixing member 141 is adjusted to block the through hole and make the connector 140 relative to the ink cartridge 10 in a preset position and posture.

[0402] like Figure 73As shown, after the connector 140 is installed, its vertical portion 1401 is attached to the inner side of the rear sidewall 50b in the ink cartridge 10, extending from the bottom of the rear sidewall 50b near the ink outlet 41 along the +Z axis to the top of the rear sidewall 50b. It is fixed to the ink cartridge 10 by the fastener 141, which seals the rear sidewall 50b, preventing ink leakage and securing the connector 140. The bent portion 1402 of the connector 140 extends out of the through hole of the fastener 141, bends away from the surface of the ink cartridge 10, and connects to a metal part on the printer, which is the aforementioned conductive support plate 82.

[0403] like Figure 72 and Figure 75 As shown, the conductive component 140a is the aforementioned carrier component. It is made entirely of conductive silicone and is embedded in the mounting surface of the ink cartridge 10, thus sealing the ink cartridge 10 while maintaining contact with the ink. Specifically, the conductive component 140a is positioned behind the chip 20, and the memory 100 is disposed on the rear surface 120b of the chip 20. The conductive component 140a has an opening 111, which is configured to fit the memory 100 so that its size is precisely sufficient to accommodate the memory 100.

[0404] In the installed state, the chip 20 is at least partially attached to the conductive element 140a on the side corresponding to the rear surface 120b. The seventh terminals 137a and 137b (the grounding terminals in this application) are both abutted against the conductive element 140a. The first surface 140b of the conductive element 140a is used to connect with the chip 20, and the second surface 140c (facing the internal cavity of the ink cartridge 10) is in contact with and electrically connected to the ink.

[0405] like Figure 76 and Figure 77 As shown, the connector 140 is positioned in the -X-axis direction of the ink cartridge 10, and the conductive component 140a is positioned in the +X-axis direction of the ink cartridge 10. Since the ink in the ink cartridge 10 has conductive properties, in this embodiment, the grounding signal between the chip 20 and the printer can be transmitted through the conductive component 140a, the ink, the connector 140, and the conductive support plate 82.

[0406] Of course, the ink cartridge grounding method described in this embodiment is also applicable to other types of chips. For example, chip 20 has four terminals on its front side and a grounding terminal (not shown in the figure) on its back side. This grounding terminal can also transmit grounding signals between the chip and the printer through conductive component 140a, ink, connector 140, and conductive support plate 82. (Component 1401 is inside the ink cartridge cavity and is electrically connected to the ink.)

[0407] After adopting the above technical solution, the grounding signal is transmitted to the chip 20 through the conductive support plate 82, connector 140, ink, and conductive component 140a, which improves stability and reduces the situation of failure to ground or unstable grounding. When the ink in the ink cartridge 10 is used up or about to be used up, the grounding signal on the chip 20 cannot be connected to the printer, and the printer will display a prompt that no ink cartridge is installed. This can serve the same purpose as the printer's own signal that the ink is exhausted, reminding the user to replace the ink cartridge.
