[0111] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0112] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0113] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0114] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0115] like Figure 1 As shown, in the prior art, the printing device 1 is provided with a communication port 10, and the prior art chip 21' is provided with an interface module 20. A communication link is established between the communication port 10 and the interface module 20, and the printing device 1 and... Figure 5 The prior art consumable chip 21' on the consumable cartridge 2 shown can transmit information via a communication link. For example, during imaging, the prior art consumable chip 21' is used to provide identification information and information on the usage status of recording materials (such as ink cartridges or toner). When the printing device 1 sends a signal to the prior art consumable chip 21', the printing device 1 is the sender and the prior art consumable chip 21' is the receiver; conversely, when the prior art consumable chip 21' sends a signal to the printing device 1, the prior art consumable chip 21' is the sender and the printing device 1 is the receiver. The information transmission process between the printing device 1 and the prior art consumable chip 21' is achieved through electrical contact between the stylus on the printing device 1 and the contact portion on the prior art consumable chip 21'.

[0116] like Figure 2As shown, the printing device 1 includes a stylus holder 11. The stylus holder 11 includes an upper stylus holder surface 111 along the Y-axis, a front stylus holder surface 112 along the X-axis, a left stylus holder side wall 1121 along the opposite direction of the Z-axis (i.e., -Z-axis), and a right stylus holder side wall 1122 along the Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular. Normally, the Y-axis is taken as the vertical direction. The upper stylus holder surface 111 includes a first slit 1111, a second slit 1112, a third slit 1113, a fourth slit 1114, a fifth slit 1115, and a sixth slit 1116. The first slit 1111, the second slit 1112, the third slit 1113, the fourth slit 1114, the fifth slit 1115, the sixth slit 1116, the first slit 1111, the second slit 1112, the third slit 1113, the fourth slit 1116 ...6, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the sixth slit 1116, the Slits 1114, 1115, and 1116 extend from the upper end face 111 of the stylus holder along the opposite direction of the Y-axis and penetrate the front end face 112 of the stylus holder in the X-axis direction. The stylus holder 11 also includes a data pin 1101, a chip select pin 1102, a clock pin 1103, a power pin 1104, and a ground pin 1105, which are respectively embedded in the first slit 1111, the second slit 1112, the third slit 1113, the fourth slit 1114, and the fifth slit 1115 of the stylus holder 11. The data pin 1101, the chip select pin 1102, the clock pin 1103, the power pin 1104, and the ground pin 1105 are respectively embedded in the first slit 1111, the second slit 1112, the third slit 1113, the fourth slit 1114, and the fifth slit 1115 of the stylus holder 11. Figure 5 The existing consumable chip 21' has a data contact SDA, a chip select contact RST, a clock contact SCL, a power contact VCC, and a ground contact GND. The contacts of the existing consumable chip 21' are arranged in two rows, with very small gaps between them. In the Y-axis direction, the lengths of the first slit 1111 and the second slit 1112 are shorter than those of the third slit 1113, the fourth slit 1114, and the fifth slit 1115, while the lengths of all the pins are the same. Thus, the pins on the pin holder are arranged such that the pins closest to the upper end face 111 of the pin holder are the data pin 1101 and the chip select pin 1102, and the tips of these two pins protrude from the upper end face 111 of the pin holder. The pins further away from the upper end face 111 of the pin holder are the clock pin 1103, the power pin 1104, and the ground pin 1105. Therefore, these three pins are embedded in the pin holder, and these three pins are at a certain distance from the upper end face 111 of the pin holder. The sixth slit 1116 does not accommodate any pins.

[0117] like Figure 3 As shown, the data probe 1101 includes a data probe tip 11011, a data probe front end 11012, a data probe bevel end 11013, a data probe tip 11014, a data probe device end 11015, a data probe rear end 11016, a data probe front junction end 11017, and a data probe rear junction end 11018, wherein the probe tip, probe front end, probe bevel end, probe rear end, probe front junction end, and probe rear junction end constitute the probe conducting part.

[0118] The data stylus tip 11011 is located at Figure 2 The upper end face 111 of the stylus holder has a data stylus front end 11012 located along the X-axis of the stylus holder front end face 112. The data stylus tip 11014 protrudes from the stylus holder front end face 112. One end of the data stylus bevel 11013 is connected to the data stylus front end 11012, and the other end is connected to the data stylus tip 11014. The front junction end 11017 of the data stylus is located at the junction of the data stylus tip 11011 and the data stylus front end 11012. The rear end 11016 of the data stylus is located on the stylus holder rear end face (not shown in the figure) that is opposite to the stylus holder front end face 112 and intersects with the upper end face 111 of the stylus holder. The rear junction end 11018 of the data stylus is located at the junction of the data stylus tip 11011 and the data stylus rear end 11016. Any part of the data stylus 1101 can form a contact portion with the terminal on the consumable chip and be electrically connected. The data pin device end 11015 is used to contact the main control board of the printing device 1. The contact conduction part of the data pin 1101 is used to conduct the electrical connection between the printing device 1 and the consumable chip. In this way, the consumable chip of the consumable box can communicate with the printing device 1 through the pin. Similarly, in addition to the data pin 1101, other pins such as the clock pin 1103, chip select pin 1102, power pin 1104, and ground pin 1105 have the same structure, so they will not be described in detail here.

[0119] In the prior art, the data contact 1101, chip select contact 1102, clock contact 1103, power contact 1104, and ground contact 1105 all make contact with the data contact SDA, chip select contact RST, clock contact SCL, power contact VCC, and ground contact GND of the consumable chip through the contact tip.

[0120] Printing device 1 sends data signals to the existing consumable chip 21' via the data contact SDA, sends a chip select signal to the existing consumable chip 21' via the chip select contact RST, sends a periodic alternating low and high level clock signal to the existing consumable chip 21' via the clock contact SCL, provides operating voltage to the existing consumable chip 21' via the power contact VCC, and provides a unified reference low level for receiving and transmitting data between printing device 1 and the existing consumable chip 21' via the ground contact GND, ensuring the correctness and stability of the communication process.

[0121] However, because the terminals on existing chips are relatively dense and the gaps between them are small, it is easy for the printer's stylus to come into contact with terminals that do not correspond to its function when the user installs or removes the consumable cartridge, causing a short circuit. Therefore, the contact parts of some terminals can be set at a position away from the contact parts of other terminals.

[0122] Example 1

[0123] like Figure 10 As shown, this application provides a consumable chip 21, which is mounted on a consumable cartridge 2. The consumable cartridge 2 is detachably mounted on a printing device 1. The consumable chip 21 includes a first substrate 210 and a connecting portion 221. The first substrate 210 includes a first plane 2101 and a second plane 2102 disposed opposite to each other. The first plane 2101 includes at least one planar terminal (hereinafter referred to as a terminal). Preferably, the planar terminal may include a chip select terminal 21012, a clock terminal 21013, a power terminal 21014, and a ground terminal 21015. The connecting portion 221 is used instead of the data terminal, thus eliminating the need for a data terminal. The first substrate 210 includes a storage module 21021, which is disposed on the second plane 2102. In some cases, the storage module 21021 may also be disposed on the first plane 2101. The chip select terminal 21012, the clock terminal 21013, the power terminal 21014, and the ground terminal 21015 are electrically connected to the storage module 21021 via wires.

[0124] Since the X-axis, Y-axis, and Z-axis have already been defined in the description of the stylus holder 11 of the printing device 1, the orientation of the consumable chip 21 is described in the posture when the consumable chip 21 is electrically connected to the printing device 1, and the orientation of the consumable cartridge 2 is described in the posture when the consumable cartridge 2 is installed in the printing device 1. Furthermore, in other embodiments, the orientation descriptions of the consumable chip 21 and the consumable cartridge 2 are consistent with Embodiment 1, and therefore will not be repeated in other embodiments.

[0125] like Figure 9As shown, the connecting portion 221 includes an extension portion 2210 and a first abutting portion 2211. One end of the extension portion 2210 is connected to the first plane 2101 of the first substrate 210, and the other end of the extension portion 2210 is connected to the first abutting portion 2211. The first plane 2101 faces the opposite direction of the X-axis (i.e., the -X-axis). The extension portion 2210 extends along the X-axis and finally connects to the first plane 2101. The first abutting portion 2211 can be bent along the Y-direction, which is approximately perpendicular to the extension direction X of the extension portion 2210; another form is that it can be bent along the Y-direction, which is approximately perpendicular to the extension direction X of the extension portion 2210, and then bent in the direction of the extension direction X of the extension portion 2210. In the Y-axis direction, the extension portion 2210 and the first abutting portion 2211 are respectively at a certain distance from the planar terminal.

[0126] like Figure 6 As shown, the consumable box 2 includes a front surface 202 facing the opposite direction of the X-axis. When the consumable box 2 is installed in the printing device 1, the front surface 202 of the consumable box is opposite to the front end face 112 of the stylus holder. At least one planar terminal and the connecting part 221 of the consumable chip 21 are used to electrically connect with a plurality of styluses of the printing device 1. For example, the stylus tip of some styluses contacts at least one planar terminal, and the stylus conductive part of another part of the styluses contacts the connecting part 221.

[0127] In this embodiment, as Figure 6 As shown, the contact between the stylus conductive part of the other part of the stylus and the connecting part 221 can be specifically that the extension part 2210 of the connecting part 221 is opposite to the upper end face 111 of the stylus holder. In this embodiment, the first abutting portion 2211 is bent along the Y direction, which is approximately perpendicular to the X direction of the extension of the extension portion 2210, and then bent again in the X direction of the extension of the extension portion 2210. There is a gap between the extension portion 2210 and the upper end face 111 of the stylus holder. The first abutting portion 2211 of the connecting portion 221 contacts the rear end 11016 of the data stylus in each contact end of the data stylus conduction portion to form a contact portion C; or the extension portion 2210 is close enough to the upper end face 111 of the stylus holder so that the extension portion 2210 can contact the top end 11011 of the data stylus and the first abutting portion 2211 can contact the rear end 11016 of the data stylus at the same time. That is, when the first abutting portion 2211 contacts the rear end 11016 of the data stylus, the extension portion 2210 contacts the top end 11011 of the data stylus.

[0128] In this embodiment, as Figure 6As shown, the contact points of some of the contact pins can contact at least one planar terminal. Specifically, the clock contact pin tip 11034 contacts the clock terminal 21013 of the consumable chip 21; the chip select contact pin tip contacts the chip select terminal 21012 of the consumable chip 21, forming a contact portion (not shown in the figure); the power contact pin tip contacts the power terminal 21014 of the consumable chip 21, forming a contact portion (not shown in the figure); and the ground contact pin tip contacts the ground terminal 21015 of the consumable chip 21, forming a contact portion (not shown in the figure). When the user installs the consumable cartridge 2 into the printing device 1 or removes the consumable cartridge 2 from the printing device 1, it is necessary to... Figure 6 As shown, the installation operation is performed from top to bottom along the Y-axis or the removal operation is performed from bottom to top along the negative Y-axis. Obviously, since the extension 2210 and the first abutment 2211 are at a certain distance from the planar terminal in the Y-axis direction, the contact part C is far enough away from the contact parts formed by other contact pins and terminals. During the installation or removal of the consumable box 2, the clock contact pin 1103 will not come into contact with the connection part 221 that transmits data signals, thus preventing a short circuit.

[0129] The first substrate 210 and the connecting portion 221 are combined to form the consumable chip 21. The specific combination method can be as follows:

[0130] 1. The connecting part 221 is detachably mounted on the consumable box 2, and then the first substrate 210 is mounted on the consumable box 2 (that is, the first substrate is detachably mounted on the consumable box 2). Finally, the first substrate 210 is electrically connected to the connecting part 221, or the first substrate is detachably mounted on the consumable box 2, then the connecting part 221 is mounted on the consumable box 2, and finally the first substrate 210 is electrically connected to the connecting part 221. Therefore, the extension 2210 of the connecting part 221 intersects with the first substrate 210. The first substrate 210 and the connecting part 221 can be electrically connected through an intermediate terminal (not shown in the figure). The intermediate terminal can be located on the first plane or the second plane of the first substrate 210. Therefore, the connecting part 221 can guide the transmission of data signals through the intermediate terminal.

[0131] 2. The connecting part 221 is fixed to the first substrate 210. Specifically, the connecting part 2210 can be fixed to the through hole of the first substrate 2210 (not shown in the figure) to form the consumable chip 21 as a whole, and then the consumable chip 21 can be detachably installed on the consumable box 2 (that is, the first substrate 210 can be detachably installed on the consumable box 2); or the first substrate 210 can be detachably installed on the consumable box 2 first, and then the connecting part 2210 can be fixed to the through hole of the first substrate 2210. In some embodiments, the consumable chip 21 can also be fixed to the consumable box 2 by means of adhesive (such as adhesive) or welding.

[0132] Preferably, in this embodiment, the connection portion 221 can also transmit a chip select signal, such as... Figure 11 As shown, the consumable chip 21 includes a connection portion 221 and a number of terminals. Preferably, the terminals can be data terminals 21011, clock terminals 21013, power terminals 21014, and ground terminals 21015. Since the chip select terminal is replaced by the connection portion 221, the chip select terminal can be omitted. The contact method between the connection portion 221 and the chip select pin 1102 can be referred to the contact method between the connection portion 221 and the data pin 1101, so it will not be described again here.

[0133] Preferably, the connection part 221 in this embodiment can also transmit a clock signal, such as Figure 12 As shown, the consumable chip 21 includes a connection portion 221 and a number of terminals. Preferably, the terminals can be data terminals 21011, chip select terminals 21012, power terminals 21014, and ground terminals 21015. Since the connection portion 221 is used instead of the clock terminal, the clock terminal can be omitted. Similarly, the contact method between the connection portion 221 and the clock contact 1103 can refer to the contact method between the connection portion 221 and the data contact 1101.

[0134] Preferably, in this embodiment, the connection portion 221 can also transmit power signals, such as... Figure 13 As shown, the consumable chip 21 includes a connection portion 221 and a number of terminals. Preferably, the terminals can be data terminals 21011, chip select terminals 21012, clock terminals 21013, and ground terminals 21015. Since the connection portion 221 replaces the power terminals, the power terminals can be omitted. Similarly, the contact method between the connection portion 221 and the power contact pin 1104 can refer to the contact method between the connection portion 221 and the data contact pin 1101.

[0135] Preferably, in this embodiment, the connection portion 221 can also transmit a grounding signal, such as... Figure 14 As shown, the consumable chip 21 includes a connection portion 221 and a number of terminals. Preferably, the terminals can be data terminals 21011, chip select terminals 21012, clock terminals 21013, and power terminals 21014. Since the connection portion 221 is used instead of the ground terminal, the ground terminal can be omitted. Similarly, the contact method between the connection portion 221 and the ground contact 1105 can be referenced to the contact method between the connection portion 221 and the data contact 1101.

[0136] Preferably, in this embodiment, the number of connecting parts 221 may be more than one, such as... Figure 15 As shown, there can be two connection parts 221 in this embodiment, which transmit two different signals respectively; the number of connection parts can also be three or four, and the number is not limited, and the corresponding replacement terminals can be omitted.

[0137] Example 2

[0138] like Figure 7 and Figure 10 As shown, the contact portion 2211 in this embodiment can be bent along a Y direction that is approximately perpendicular to the extension direction X of the extension portion 2210; another form is that it can be bent along a Y direction that is approximately perpendicular to the extension direction X of the extension portion 2210, and then bent towards the extension direction X of the extension portion 2210. The difference between this embodiment and embodiment 1 is that the contact portion 2211 of the connecting portion 221 contacts the tip 11011 of the data pin in each contact end of the data pin conduction portion, forming a contact portion C. At this time, the extension portion 2210 of the connecting portion 221 is opposite to the upper end surface 111 of the pin holder and there is a certain distance between them without contact. Since the tips of the data pins 1101 and the chip select pins 1102 are exposed on the upper end surface 111 of the pin holder, the connecting portion 221 in this embodiment can be used to transmit chip select signals, such as... Figure 11 As shown, the connecting part 221 replaces the chip select terminal, thus eliminating the need for the chip select terminal. The contact method between the connecting part 221 and the chip select contact pin 1102 can be referred to the contact method between the connecting part 221 and the data contact pin 1101, so it will not be described again here. In addition, the connecting part 221 in this embodiment can also be used to transmit data signals and chip select signals. Preferably, there can be two connecting parts 221, which respectively transmit data signals and chip select signals. That is, two connecting parts 221 replace the data terminal and the chip select terminal respectively, thus eliminating the need for the data terminal and the chip select terminal.

[0139] Example 3

[0140] like Figure 2 As shown, since the clock contact 1103, power contact 1104, and ground contact 1105 are embedded in the gaps of the contact holder 11, which include a third gap 1113, a fourth gap 1114, and a fifth gap 1115, and the clock contact 1103, power contact 1104, and ground contact 1105 are a certain distance from the upper end face 111 of the contact holder, compared to Embodiment 2, the first abutting portion 2211 of the connecting portion 221 in this embodiment is longer, and the number can be one, two, or three, with no limit on the number, and can extend into the third gap. The first abutment 2211 can be inserted in any one, two, or three of the gaps 1113, 1114, and 1115, respectively, to contact the tips of the clock contact 1103, power contact 1104, and ground contact 1105. The first abutment 2211 can be inserted in an embedded manner, making the contact between the connecting part 221 and the contact pin holder 11 tighter; alternatively, a gap can be left between the first abutment 2211 and any one, two, or three of the gaps 1113, 1114, and 1115.Figure 8 , 12 As shown in -14, the connection part 221 of this embodiment can contact any one, any two, or any three of the clock contact tip, power contact tip, and ground contact tip.

[0141] Of course, different forms of the connecting portion 221 in embodiments 1-3 can also be combined to contact the tip and / or rear end of the contact in each contact of the contact pin conductive portion. In addition, the first abutting portion 2211 of the connecting portion 221 can also contact the front junction end 11017 or the rear junction end 11018 of the data contact in each contact of the contact pin conductive portion.

[0142] When the consumable box 2 is installed in the printing device 1, it can be installed and contacted with the stylus holder 11 by setting a structure such as a spring, a snap-fit ​​part, or a slide rail in the connecting part 221. The connecting part 221 can be set as an elastic structure or a rigid structure.

[0143] Example 4

[0144] like Figure 16 As shown, the first substrate 210 of the consumable chip 21 in this embodiment includes at least one terminal. Preferably, the terminal may be a data terminal 21011, a chip select terminal 21012, a power supply terminal 21014, or a ground terminal 21015. Figure 18 This is a schematic diagram showing the first substrate 210 being mounted on the consumable box 2 and connected to the connecting portion 221. The extension 2210 of the connecting portion 221 is electrically connected to the first substrate 210, therefore, the extension 2210 of the connecting portion 221 intersects with the first substrate 210. The tips of some of the pins in the printing device 1 contact at least one planar terminal, while the tips of other pins contact the connecting portion 221. Specifically, these include data pin 1101, chip select pin 1102, and power pin 1104. The tip of the grounding contact 1105 contacts the data terminal 21011, the chip select terminal 21012, the power terminal 21014, and the ground terminal 21015, respectively. At least a portion of the first abutment portion 2211 of the connection portion 221 is exposed outside the first substrate 210, and the exposed portion of the first abutment portion 2211 of the connection portion 221 contacts the tip of the clock contact 1103. The first substrate 210 and the connection portion 221 are combined to form a consumable chip 21. The specific combination method can be:

[0145] 1. For example Figure 17As shown, the connecting part 221 is installed on the consumable box 1, and then the first substrate 210 is installed on the consumable box 2. The first substrate 210 and the connecting part 221 are electrically connected through the extension part 2210. The electrical connection position is located on the second plane 2102 of the first substrate 210. Therefore, the extension part 2210 can intersect with the second plane 2102 of the first substrate 210. Alternatively, the first substrate 210 is installed on the consumable box 1, and then the connecting part 221 is installed on the consumable box 2. The first substrate 210 and the connecting part 221 are electrically connected through the extension part 2210. The electrical connection position is located on the first plane 2101 of the first substrate 210. Therefore, the extension part 2210 can intersect with the first plane 2101 of the first substrate 210. Thus, through the extension part 2210, the connecting part 221 can guide the transmission of the clock signal.

[0146] 2. The connecting part 221 is fixed to the first substrate 210. Specifically, the connecting part 2210 can be fixed to the through hole of the first substrate 2210 (not shown in the figure) to form the consumable chip 21 as a whole, and then the consumable chip 21 can be installed on the consumable box 2; or the first substrate 210 can be installed on the consumable box 2 first, and then the connecting part 2210 can be fixed to the through hole of the first substrate 2210.

The first substrate 210 also includes a first cutout portion 2100, which passes through the space between the first plane 2101 and the second plane 2102, allowing the power contact 1104 to pass through the first plane 2101. Figure 20 This is a schematic diagram showing the first substrate 210 being mounted on the consumable box 2 and engaging with the connecting portion 221. The extension 2210 of the connecting portion 221 intersects with the first substrate 210. The first cutout portion 2100 is used to expose at least a portion of the first abutting portion 2211.

[0149] The exposed portion of the first abutting portion 2211 of the connecting portion 221 is used to contact the tip of the power contact pin 1104 passing through the first plane 2101. The connecting portion 221 can transmit power signals, that is, the printing device 1 provides working voltage to the consumable chip 21 through the connecting portion 221. The first substrate 210 and the connecting portion 221 are combined to form the consumable chip 21. The combination method is similar to that in Embodiment 4.

The extension portion 2210A of connection portion 221A and the extension portion 2210B of connection portion 221B are respectively connected to the first substrate. The plates 210 have an intersection. The first cutout portion 2100 is used to expose at least a portion of the first abutting portion 2211A and the first abutting portion 2211B.

Preferably, the terminal can be a clock terminal 21013, a power terminal 21014, or a ground terminal 21015. The number of connection portions can be two. Connection portion 221A can transmit data signals, and connection portion 221B can transmit chip select signals. The first substrate 210 does not include a first cutout portion. Instead, at least a portion of the first abutting portion 2211A of connection portion 221A and at least a portion of the first abutting portion 2211B of connection portion 221B are exposed outside the first substrate 210.

The connecting part 221A can transmit data signals through the extension 2210A, and the connecting part 221B can transmit chip select signals through the extension 2210B. Compared with other embodiments, this embodiment can effectively reduce the area of ​​the first substrate 210 of the consumable chip 21.

[0156] Example 9

[0157] like Figure 24As shown, the first substrate 210 of the consumable chip 21 in this embodiment includes at least one terminal. Preferably, the terminal can be a ground terminal 21015. The number of connection portions can be four, wherein connection portion 221A can transmit data signals, connection portion 221B can transmit chip select signals, connection portion 221C can transmit clock signals, and connection portion 221D can transmit power signals.

It also includes a power module 21022, which can be a capacitor or a battery, and can supply power to the consumable chip 21. Specifically, if the power module 21022 only includes a capacitor, the consumable chip 21 can obtain power from the chip select signal or clock signal when the level is high, and then store it in the power module 21022. When the level of the chip select signal or clock signal is low, power can be extracted from the power module 21022 to power the consumable chip 21 for normal operation. If the power module 21022 includes both a capacitor and a battery, the battery can supply power when the power in the capacitor is too low to power the consumable chip 21. If the power module 21022 only includes a battery, the power of the consumable chip 21 is provided solely by the battery. At this time, the consumable chip 21 does not include a power terminal, and the consumable chip 21 is not in contact with the power contact pin 1104.

[0160] Example 11

Preferably, there are two first embedding portions 2212 and two extension portions 2210. One end of each of the two extension portions 2210 is connected to the first substrate 210, and the other end of each extension portion 2210 is connected to a different first embedding portion 2212. The two extension portions 2210 extend from the first substrate 210 in opposite directions along the Y-axis (i.e., -Y-axis). 212 extends from the extension portion 2210 along the opposite direction of the X-axis (i.e., the -X-axis), and the first abutment portion 2211 is connected to two first embedding portions 2212 respectively; the gap portion includes a third gap 1113 and a fourth gap 1114, and the two first embedding portions 2212 can be embedded into the third gap 1113 and the fourth gap 1114 respectively, so that the consumable chip 21 is stably installed, and the first abutment portion 2211 contacts the tip or the rear end of the data contact pin; in other ways, there may be only one first embedding portion 2212, which can be embedded into the third gap 1113 or the fourth gap 1114. The connecting portion 221 can be located on the first plane 2101 or the second plane 2102 of the first substrate 210, and the position is not limited.

[0162] Example 12

[0163] The difference between this embodiment and embodiment 11 is that, as Figure 27As shown, the slit portion includes a fourth slit 1114 and a sixth slit 1116.

The consumable chip 21 includes a first substrate 210 and a connecting portion 211. The first substrate 210 includes a first plane 2101 and a second plane 2102 disposed opposite to each other, as shown... Figure 29 As shown, the first plane 2101 includes at least one planar terminal (hereinafter referred to as the terminal). Preferably, the planar terminal may include a chip select terminal 21012 (i.e., the second terminal), a clock terminal 21013 (i.e., the third terminal), a power supply terminal 21014 (i.e., the fourth terminal), and a ground terminal 21015 (i.e., the fifth terminal). By using the connection portion 221 instead of the data terminal (i.e., the first terminal), the data terminal can be omitted; as Figure 30 As shown, the second plane 2102 includes a storage module 21021. In some cases, the storage module 21021 may also be disposed on the first plane 2101. The connection part 211, chip select terminal 21012, clock terminal 21013, power terminal 21014, and ground terminal 21015 are electrically connected to the storage module 21021 via wires.

[0166] like Figure 31 and Figure 45As shown, the connecting portion 211 is snapped or soldered to the first substrate 210. The connecting portion 211 includes a first connecting structure 2111, which further includes a second abutting portion 21110 and a third abutting portion 21111. One end of the third abutting portion 21111 is connected to the first plane 2101 of the first substrate 210, and the other end of the third abutting portion 21111 is connected to the second abutting portion 21110. The first plane 2101 faces the opposite direction to the X-axis (i.e., the -X-axis). 1111 extends from the first plane 2101 along the direction of -X axis towards -Y axis, so the third abutment portion 21111 is not parallel to the X axis direction. The second abutment portion 21110 extends from the other end of the third abutment portion 21111 along the direction of X axis towards Y axis, so the second abutment portion 21110 is also not parallel to the X axis direction. The second abutment portion 21110 and the third abutment portion 21111 roughly form a V shape, and the opening of the V shape faces the first plane 2101. The angle of the V shape is an acute angle.

[0167] Preferably, in order to ensure that the connecting portion 211 is stably fixed to the first substrate 210, such as... Figure 32 As shown, the connecting portion 211 also includes a second connecting structure 2112. The second connecting structure 2112 is connected to the third abutting portion 21111 of the first connecting structure 2111 and the first plane 2101 of the first substrate 210. The second connecting structure 2112 can increase the connection area between the first connecting structure 2111 and the first substrate 210, so that the first connecting structure is more stably fixed to the first substrate 210.

[0168] like Figure 29 and Figure 30 As shown, the first substrate 210 includes a second cutout portion that penetrates between the first plane 2101 and the second plane 2102. Preferably, there are two second cutout portions, namely a second cutout portion 212A and a second cutout portion 212B, as shown. Figure 33As shown, the consumable box 2 includes an upper surface 201 facing the Y-axis and a front surface 202 facing the opposite direction of the X-axis. The front surface 202 of the consumable box 2 includes a first protrusion extending from the front surface 202 along the opposite direction of the X-axis. Preferably, there are two first protrusions, namely a first protrusion 2021A and a first protrusion 2021B. The first protrusions 2021A and 2021B can respectively engage with the second cutouts 212A and 212B. The first protrusions 2021A and 2021B can move within the second cutouts 212A and 212B respectively, allowing the first substrate 210 to move from a first position to a second position. That is, the above arrangement allows the first substrate 210 to move between the first and second positions on the consumable box 2. When the consumable box 2 is installed in the printing device 1, the first substrate 210... Figure 34 The first position shown is moved to Figure 37 The second position shown.

[0169] like Figure 33 As shown, the consumable box 2 also includes a handle 2020 disposed on the front surface 202 of the consumable box. The handle 2020 includes a handle bottom end 20201, as shown. Figure 34 As shown, the consumable chip 21 can be adhered to the front surface 202 of the consumable box 2. The top of the consumable chip 21 is a certain distance from the bottom end 20201 of the handle, and the distance between the bottom end of the consumable chip 21 and the bottom end of the consumable box 2 is L1. After the consumable chip 21 is installed in the consumable box 2, the first protrusion 2021A of the front surface 202 of the consumable box 2 protrudes from the second hollowed-out portion 212A, and the first protrusion 2021B protrudes from the second hollowed-out portion 212B. The first protrusion 2021A and... Figure 29 The top end 2121A of the second hollow portion of the consumable chip 21 is in contact with the top end 2121B of the second hollow portion, and the first protrusion 2021B is in contact with the top end 2121B of the second hollow portion.

[0170] like Figure 35 and Figure 36 As shown, when the consumable cartridge 2 is installed into the printing device 1, the consumable chip 21 moves upward along the R direction, which is perpendicular to the direction of the printer. Figure 39 The Y-axis direction is consistent. After the consumable box 2 is installed into the printing device 1, as follows: Figure 37 As shown, the distance between the bottom of the consumable chip 21 and the bottom of the consumable box 2 is L2. At this time, L2 is greater than L1, and the first protrusion 2021A and Figure 29 The bottom end 2122A of the second hollow portion of the consumable chip 21 is in contact with the first protrusion 2021B, and the bottom end 2122B of the second hollow portion is in contact with the first protrusion 2021B. The top end of the consumable chip 21 is close to the bottom end 20201 of the handle.

[0171] like Figure 39As shown, the front surface 202 of the consumable box is opposite to the front end surface 112 of the stylus holder. At least one planar terminal and the connecting part 221 of the consumable chip 21 are used to electrically connect with multiple stylus pins of the printing device 1. For example, the stylus tip of some stylus pins contacts at least one planar terminal, and the stylus tip of other stylus pins contacts the connecting part 221. Specifically, the second abutting part 21110 of the first connecting structure 2111 of the connecting part 211 is opposite to the upper end surface 111 of the stylus holder. The chip select stylus tip, clock stylus tip, power stylus tip, and ground stylus tip respectively contact the chip select terminal 21012, clock terminal 21013, power terminal 21014, and ground terminal 21015 of the consumable chip 21 to form an electrical connection. The data stylus tip does not form an electrical connection with the first substrate 210, but the top end 11011 of the data stylus tip contacts the second abutting part 21110 of the consumable chip 21 to form an electrical connection.

[0172] When the user installs consumable cartridge 2 into printer 1, they need to do as follows: Figure 39 As shown, the consumable box 2 is installed from top to bottom along the opposite direction of the Y-axis. Figure 35 As shown, when the consumable cartridge 2 is installed into the printing device 1, due to the installation force, the consumable chip 21 moves upward. The first connecting structure 2111 of the connecting part 211 is used to contact the tip of the stylus and undergo elastic deformation, so that a rigid contact with relative movement is formed between the connecting part 211 and the tip of the stylus conductor. Specifically, when the second abutting part 21110 contacts the tip of the stylus, the relative position of the third abutting part 21111 and the second abutting part 21110 changes to form elastic deformation, that is, the second abutting part 21110 and the third abutting part 21111 bend along the direction close to the first substrate 210 to form elastic deformation. After the consumable cartridge 2 is installed into the printing device 1, as shown... Figures 38-39 As shown, the second contact portion 21110 is approximately parallel to the upper end face 111 of the stylus holder.

[0173] This embodiment can flexibly adapt to the offset that occurs during the installation of the consumable box, so that the terminals of that part make precise contact with the corresponding contact pins.

[0174] Example 14

[0175] like Figure 40 As shown, the printing device 1 also includes a receiving groove 12 for accommodating the stylus holder 11, the receiving groove 12 including a first receiving wall 121 and a second receiving wall 122 disposed opposite to each other; as Figure 41 As shown, the stylus holder 11 is snapped into the receiving groove 12; as Figure 42As shown, the stylus holder 11 includes a left side wall 1121 and a right side wall 1122. A first gap 13 exists between the first receiving wall 121 and the left side wall 1121, and a second gap 14 exists between the second receiving wall 122 and the right side wall 1122. The first gap 13 and the second gap 14 constitute a gap portion. A preferred embodiment is as follows: Figure 43 As shown, the front surface 202 of the consumable box 2 includes a fifth protrusion. The fifth protrusion extends from the front surface 202 of the consumable box in the opposite direction along the X-axis. There are two fifth protrusions, namely the fifth protrusion 2023A and the fifth protrusion 2023B. After the consumable box 2 is installed into the printing device 1, the fifth protrusion 2023A and the fifth protrusion 2023B are respectively embedded in the first gap 13 and the second gap 14, stabilizing the consumable box 2 from both ends. The consumable box 2 is not easy to shake from side to side, thereby fixing the consumable box 2 to the printing device 1. In addition, the gaps can be formed by opening the first gap 13 and the second gap 14 on the receiving groove 12, instead of the first receiving wall 121 and the left side wall 1121 of the stylus holder forming the first gap 13 and the second receiving wall 122 and the right side wall 1122 of the stylus holder forming the second gap 14. The positions of the fifth protrusion 2023A and the fifth protrusion 2023B in the consumable box 2 are adjusted accordingly based on the first gap 13 and the second gap 14. This method can also fix the consumable box 2 to the printing device 1.

[0176] Example 15

[0177] like Figure 28 As shown, the stylus holder 11 of this embodiment differs from stylus holders 11 of other embodiments in that the stylus holder 11 of this embodiment includes two second embedding portions, namely, second embedding portion 1110A and second embedding portion 1110B. The second embedding portions 1110A and 1110B extend from the upper end face 111 of the stylus holder along opposite directions of the Y-axis, and sequentially penetrate the front end face 112 of the stylus holder in the X-axis direction, penetrate the opposite side of the front end face 112 of the stylus holder in the opposite direction of the X-axis, and penetrate the upper end face 111 of the stylus holder in the Y-axis direction. A preferred embodiment is as follows: Figure 44As shown, the first substrate 210 of the consumable chip 21 also includes a sixth protrusion. The sixth protrusion extends from the first plane 2101 of the first substrate 210 along the opposite direction of the X-axis. There are two sixth protrusions, namely the sixth protrusion 214A and the sixth protrusion 214B. The sixth protrusions 214A and 214B are respectively embedded in the second embedding portions 1110A and 1110B, so that the first substrate 210 is fixed to the stylus holder 11, thereby making the consumable chip 21 more securely mounted on the stylus holder 11. Of course, for the sake of saving materials, one implementation is that the consumable chip 21 only needs to include one of the sixth protrusions 214A or 214B.

[0178] Example 16

[0179] like Figure 45 As shown, this embodiment is a material-saving implementation of embodiment 13. In this embodiment, the connection part 211 of the consumable chip 21 only includes the first connection structure 2111 and does not include the second connection structure 2112. The first connection structure 2111 is directly connected to the first plane 2101 of the first substrate 210 through one end of the third abutment part 21111.

[0180] Example 17

[0181] like Figure 46 As shown, this embodiment is another material-saving implementation of embodiment 13. The consumable chip 21 in this embodiment does not include the second hollow portion 212A or the second hollow portion 212B. The consumable chip 21 is fixedly mounted on the consumable box 2. Using the force of the consumable box during the installation operation from top to bottom, the first connecting structure 2111 deforms, and at the same time, the second abutting portion 21110 bends along the direction close to the first substrate 210, so that the second abutting portion 21110 and the top tip 11011 of the data contact pin make elastic contact to form an electrical connection.

[0182] Example 18

[0183] like Figure 48 and Figure 49 As shown, the first plane 2101 of the first substrate 210 of the consumable chip 21 includes a connecting portion 211, which extends from the first plane 2101 of the first substrate 210 along the opposite direction of the X-axis. The connecting portion 211 includes a second abutting portion 21110, which is generally oriented towards the -X-axis and biased towards the -Y-axis. The second plane 2102 of the first substrate 210 of the consumable chip 21 includes a first connecting structure 2111, as shown in the figure. Figure 47As shown, the front surface 202 of the consumable cartridge 2 in this embodiment includes a second protrusion 2025, a third protrusion 2022, and a fourth protrusion 2024 sequentially arranged along a first direction, the first direction being the Y-axis direction. The second protrusion 2025, the third protrusion 2022, and the fourth protrusion 2024 extend from the front surface 202 of the consumable cartridge in opposite directions along the X-axis. When the consumable cartridge is not installed in the printing device, such as... Figure 50 As shown, the top and bottom ends of the first connecting structure 2111a (i.e., the first form of the first connecting structure 2111) are in contact with the third protrusion 2022 and the second protrusion 2025, respectively. When the consumable box 2 is installed into the printing device 1, the first connecting structure 2111 is elastic, and the first connecting structure 2111 undergoes elastic deformation and is stretched upward along the R direction (i.e., the first connecting structure 2111 undergoes elastic deformation in the first direction). The R direction is perpendicular to the... Figure 39 The Y-axis direction is consistent, and the top and bottom ends of the first connecting structure 2111b (i.e., the second form of the first connecting structure 2111) are in contact with the fourth protrusion 2024 and the second protrusion 2025, respectively. Figure 51 As shown, due to the tensile force applied by the first connecting structure 2111, the first substrate 210 of the consumable chip 21 also moves upward along the R direction (that is, the first substrate 210 moves from the first position to the second position). The contact between the second abutment 21110 and the data pin tip 11011 changes from the original relatively fixed rigid contact between the data pin tip 11011 and the second abutment 21110 to a relatively moving rigid contact, making the contact between the two more precise.

[0184] Example 19

[0185] like Figure 52 and Figure 53As shown, the consumable chip 21 includes a first substrate 210, an elastic structure 217, and a connecting portion 211. The connecting portion 211 is located on a first plane 2101 of the first substrate 210 and extends from the first plane 2101 of the first substrate 210 in the opposite direction to the X-axis. The connecting portion 211 includes a second abutting portion 21110, which is generally oriented towards the -X-axis and biased towards the -Y-axis. The elastic structure 217 includes a first contact portion 2171, a first connecting structure 2111, and a second contact portion 2172. The first connecting structure 2111 is used to connect the first contact portion 2171 and the second contact portion 2172. The second contact portion 2172 is disposed on the second plane 2102 of the first substrate 21 of the consumable chip 21 and connected to the first substrate 21. The elastic structure 217 connects to the consumable cartridge 2 via the first contact portion 2171. The consumable cartridge front surface 202 is connected to the consumable cartridge 2. When the consumable cartridge 2 is not installed in the printing device 1, the first connecting structure 2111 is not parallel to the X-axis direction, and the distance between the second plane 2102 and the top of the connecting part 211 is d1. At this time, the first substrate 210 is in the first position. When the consumable cartridge 2 is installed in the printing device 1, the elastic structure 217 abuts against the front surface 202 of the consumable cartridge, and the first connecting structure 2111 undergoes elastic deformation, gradually becoming parallel to the X-axis direction. Due to the elastic deformation force, the consumable chip 21 moves upward along the direction R, and at the same time moves in the opposite direction to the X-axis. The first connecting structure 2111 of the elastic structure 217 moves the first substrate 210 from the first position to the second position. The distance between the position of the second plane 2102 before installation and the top of the connecting part 211 after installation is d2, and d2 is greater than d1. After the consumable cartridge 2 is installed in the printing device 1, the second abutting part 21110 contacts the top of the data stylus 11011.

[0186] The contact between the second abutment 21110 and the tip of the data stylus 11011 has changed from a relatively fixed rigid contact between the tip of the data stylus 11011 and the second abutment 21110 to a relatively movable rigid contact, making the contact between the two more precise.

[0187] The number of terminals on the consumable chip of this application that are electrically connected to the contact pins is not limited to 5, but can be other numbers, without limitation.

[0188] This application also provides a consumable box 2, including the consumable chip 21 described in any of embodiments 1-19.

[0189] The storage module can specifically include a control unit and a storage unit. The storage unit can be a common non-volatile storage unit, such as EPROM, EEPROM, FLASH, ferroelectric storage unit, phase-change storage unit, etc., or it can be a volatile storage unit plus a power supply, such as SRAM plus a battery or capacitor, DRAM plus a battery or capacitor, etc. The control unit is used to control the communication between the consumable chip 21 and the printing device 1. The printing device 1 reads information from the storage module and stores information in the storage module. The control unit can be a microcontroller (MCU), FPGA, ASIC, etc. The type of storage module can be selected according to actual needs and is not limited here.

[0190] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model. Those skilled in the art will understand that the various functional units or modules in the present utility model can be partially implemented by computer programs or by related hardware circuits, and this is not limited thereto.
