Description

Technical Field

[0002] During the printing imaging process, the printing device needs the assistance of the imaging auxiliary information of the consumable box to complete the imaging process. In addition to being recorded in the printing device, the imaging auxiliary information of the printing device is also recorded on the consumable chip. The consumable chip can be installed on the consumable box, which can be an ink cartridge filled with ink or a toner cartridge filled with toner. The ink cartridge and toner are recording materials. The function of the consumable chip is to control the authentication and data matching between the consumable box and the printing device, and to provide imaging auxiliary information in the subsequent imaging process. The consumable chip is provided with a storage module and a terminal for electrical connection to the contact pin of the printing device. The storage module stores relevant information such as colorant quantity information, manufacturer information, serial number, etc.

[0063] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0064] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0065] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0066] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0067] like Figure 1 As shown, in the prior art, a communication port 10 is provided on the printing device 1, and an interface module 20 is provided on the prior art chip 21'. A communication link is established between the communication port 10 and the interface module 20. The printing device 1 and Figure 5 The prior art consumable chip 21' on the consumable box 2 shown can transmit information through a communication link. For example, during the imaging process, the prior art consumable chip 21' is used to provide identity recognition information and recording material (such as ink cartridges or toner) usage status information. 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; and 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 by electrical contact between the contact pins on the printing device 1 and the contact parts on the prior art consumable chip 21'.

[0068] like Figure 2As shown, the printing device 1 includes a stylus holder 11, which includes an upper end surface 111 of the stylus holder along the Y axis, a front end surface 112 of the stylus holder along the X axis, and a right end surface 113 of the stylus holder along the Z axis. The X axis, the Y axis, and the Z axis are perpendicular to each other. It is defined that the X axis and the opposite direction of the X axis (i.e., the -X axis) together constitute a first direction, the Y axis and the opposite direction of the Y axis (i.e., the -Y axis) together constitute a second direction, and the Z axis and the opposite direction of the Z axis (i.e., the -Z axis) together constitute a third direction. Generally, the second direction is taken as the vertical direction. The upper end surface 111 of the stylus holder includes a first slit 1111, a second slit 1112, a third slit 1113, and a fourth slit 1114. The first slit 111 1. The second slit 1112, the third slit 1113, and the fourth slit 1114 extend from the upper end surface 111 of the stylus holder in the opposite directions along the Y axis and penetrate the front end surface 112 of the stylus holder in the X axis direction, wherein the first slit 1111 and the second slit 1112 together constitute a first matching portion, and the third slit 1113 and the fourth slit 1114 together constitute a second matching portion. The stylus holder 11 also includes a first short-circuit detection pin 1101, a reset pin 1102, a clock pin 1103, a second short-circuit detection pin 1104, a first high-voltage pin 1105, a power pin 1106, a ground pin 1107, a data pin 1108, and a second high-voltage pin 1109, which are respectively connected to Figure 4 The prior art consumable chip 21' shown includes a first short-circuit detection contact NC1, a reset contact RST, a clock contact SCL, a second short-circuit detection contact NC2, a first high-voltage contact A, a power contact VCC, a ground contact GND, a data contact SDA, and a second high-voltage contact B. The contacts of the prior art consumable chip 21' are arranged in two rows, one above the other, resulting in a relatively large chip size. Furthermore, after the consumable cartridge 2 is installed in the printing device 1, the prior art consumable chip 21' is prone to displacement on both sides of its top, causing the prior art short-circuit detection terminal to deviate from the two short-circuit detection contact pins.

[0069] The printing device 1 detects whether the consumable chip is successfully installed through the first short-circuit detection contact part NC1 and the second short-circuit detection contact part NC2, and determines whether the consumable chip is short-circuited by whether an electrical signal change is generated between these two contacts and other contacts; the printing device 1 sends a reset signal to the consumable chip 21' of the prior art through the reset contact part RST; the printing device 1 sends a periodic low-level and high-level alternating and repeated clock signal to the consumable chip 21' of the prior art through the clock contact part SCL; the printing device 1 detects whether the consumable chip is successfully installed through the first high-voltage contact part A and the second high-voltage contact part B, and receives a higher operating voltage. In some scenarios, the ink amount can be detected by a higher voltage; the printing device 1 provides an operating voltage for the consumable chip 21' of the prior art through the power contact part VCC; the printing device 1 sends a data signal to the consumable chip 21' of the prior art through the data contact part SDA; the printing device 1 provides a unified reference low level for receiving and sending data between the printing device 1 and the consumable chip 21' of the prior art through the ground contact part GND, thereby ensuring the correctness and stability of the communication process.

[0070] like Figure 3As shown, the first short-circuit detection stylus 1101 includes a first short-circuit detection stylus top 11011 (referred to as the first top), a first short-circuit detection stylus front end 11012, a first short-circuit detection stylus oblique end 11013, a first short-circuit detection stylus tip 11014, and a first short-circuit detection stylus side end 11015 (referred to as the first side), all of which can form a contact portion with the short-circuit detection terminal on the consumable chip and be electrically connected. Along the Y-axis direction, the first short-circuit detection stylus tip 11014 is connected to the first short-circuit detection stylus oblique end 11013, the first short-circuit detection stylus oblique end 11013 is connected to the first short-circuit detection stylus front end 11012, and the first short-circuit detection stylus front end 11012 is connected to the first short-circuit detection stylus top 11011. The first short-circuit detection stylus side end 11015 is respectively connected to the first short-circuit detection stylus oblique end 11013 and the first short-circuit detection stylus tip 11014. The structure of the second short-circuit detection pin 1104 is consistent with that of the first short-circuit detection pin 1101, except that the second short-circuit detection pin side end (not shown in the figure, referred to as the second side end) of the second short-circuit detection pin 1104 is arranged relative to the first short-circuit detection pin side end 11015, so the specific structure of the second short-circuit detection pin 1104 will not be described again. The short-circuit detection pin device end (not shown in the figure) is used to contact the main control board of the printing device 1, so that the consumable chip of the consumable box 2 can realize the communication process with the printing device 1 through the pin. In the prior art, when the consumable chip accommodates 9 terminals, the size is often too large. In addition, after the consumable box 2 is installed on the printing device 1, the consumable chip is prone to displacement on both sides of the upper side, causing the short-circuit detection terminal of the prior art to deviate from the two short-circuit detection pins. Therefore, the short-circuit detection terminal with fewer functions can be cancelled and connected to the short-circuit detection pin of the printing device 1 through other additional connecting components.

[0071] like Figure 6-7 As shown, the consumable chip 21 includes a first substrate 211, the first substrate 211 includes a first plane 2101 and a second plane 2102, the first plane 2101 includes a reset terminal 212, a clock terminal 213, a first high-voltage terminal 215, a power terminal 216, a ground terminal 217, a data terminal 218, and a second high-voltage terminal 219, and the second plane 2102 includes a storage module 21021; the reset terminal 212, the clock terminal 213, the first high-voltage terminal 215, the power terminal 216, the ground terminal 217, the data terminal 218, and the second high-voltage terminal 219 are electrically connected to the storage module 21021 through wires, and each terminal of the consumable chip 21 is physically electrically contacted with the corresponding contact pins on the contact pin holder 11 of the printing device 1 to achieve electrical connection.

[0072] Example 1

[0073] like Figure 8-9As shown, the present application provides a connecting portion 22 for being detachably mounted on a printing device 1 and electrically connected to the printing device 1. The connecting portion 22 includes a first extension portion 221 and a second extension portion 222. The second extension portion 222 is electrically connected to the first extension portion 221. When the connecting portion 22 is electrically connected to the printing device 1, the first extension portion 221 is used to contact the first short-circuit detection contact pin 1101, and the second extension portion 222 is used to contact the second short-circuit detection contact pin 1104, so that an electrical connection is formed between the first short-circuit detection contact pin 1101 and the second short-circuit detection contact pin 1101.

[0074] Since the above description of the stylus holder 11 of the printing device 1 has defined that the X-axis and the direction opposite to the X-axis (i.e., the -X-axis) together constitute the first direction, the Y-axis and the direction opposite to the Y-axis (i.e., the -Y-axis) together constitute the second direction, and the Z-axis and the direction opposite to the Z-axis (i.e., the -Z-axis) together constitute the third direction, the orientation description of the connecting portion 22 is based on the position when the connecting portion 22 is electrically connected to the printing device 1, and the orientation description of the consumables box 2 is based on the position when the consumables box 2 is installed in the printing device 1. In addition, in other embodiments, the orientation description of the connecting portion 22 and the consumables box 2 is consistent with that of Example 1, and therefore will not be repeated in other embodiments.

[0075] like Figure 8-9 As shown, the connecting portion 22 includes a conductive portion 220, which extends along the third direction. The two ends of the conductive portion 220 in the third direction are electrically connected to the first extension portion 221 and the second extension portion 222 respectively, so that an electrical connection is formed between the second extension portion 222 and the first extension portion 221. At this time, the connecting portion 22 as a whole is conductive; the first extension portion 221 extends from the conductive portion 220 along the opposite direction of the Y axis. Specifically, the first extension portion 221 has a first end and a second end in the second direction. The first end of the first extension portion 221 is connected to the conductive portion 220 in the Y axis direction, and the second end of the first extension portion 221 faces the opposite direction of the Y axis. The second extension portion 222 extends along the opposite direction of the Y axis. Specifically, the second extension portion 222 has a first end and a second end in the second direction. The first end of the second extension portion 222 is connected to the conductive portion 220 in the Y axis direction, and the second end of the second extension portion 222 faces the opposite direction of the Y axis.

[0076] like Figure 8-9As shown, the first extension portion 221 is used to contact the top end 11011 of the first short-circuit detection contact pin. Specifically, the first extension portion 221 includes a first abutting portion 2210, which is located at the second end of the first extension portion 221 in the second direction. The first abutting portion 2210 extends from the first extension portion 221 in the opposite direction of the Y-axis. The first abutting portion 2210 is an elastic member, so that the first abutting portion 2210 is elastic, so that the first abutting portion 2210 is deformed in the second direction when the first abutting portion 2210 contacts the top end 11011 of the first short-circuit detection contact pin, which can ensure close contact between the first abutting portion 2210 and the top end 11011 of the first short-circuit detection contact pin, thereby improving the conductive performance; or the first abutting portion 2210 can also be a rigid member.

[0077] like Figure 8-9 As shown, the second extension portion 222 is used to contact the top end of the second short-circuit detection contact pin (not shown in the figure, referred to as the second top end). Specifically, the second extension portion 222 includes a second abutting portion 2220, which is located at the second end of the second extension portion 222 in the second direction. The second abutting portion 2220 extends from the second extension portion 222 in the opposite direction of the Y-axis. The second abutting portion 2220 is an elastic member, so that the second abutting portion 2220 is elastic, so that the second abutting portion 2220 is deformed in the second direction when the second abutting portion 2220 contacts the top end of the second short-circuit detection contact pin, which can ensure close contact between the second abutting portion 2220 and the top end of the second short-circuit detection contact pin, thereby improving the conductive performance; or the second abutting portion 2220 can also be a rigid member.

[0078] like Figure 9As shown, when the connecting portion 22 is electrically connected to the printing device 1, the connecting portion 22 is first installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, and then the connecting portion 22 is moved a certain distance along the opposite direction of the Y axis. The specific connection method is that when the connecting portion 22 is installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, the first abutting portion 2210 of the connecting portion 22 has a certain distance from the first short-circuit detection stylus tip 1101 of the first short-circuit detection stylus 1101 in the second direction, and the connecting portion 22 is moved a certain distance along the opposite direction of the Y axis or the opposite direction of the X axis. The second abutting portion 2220 of the connecting portion 2 is at a certain distance from the top end of the second short-circuit detection contact pin 1104 (not shown in the figure) in the second direction, and then the connecting portion 22 is moved a certain distance in the opposite direction of the Y-axis, so that the first abutting portion 2210 of the connecting portion 22 contacts the first short-circuit detection contact pin top 11011 of the first short-circuit detection contact pin 1101 in the opposite direction of the Y-axis, and the second abutting portion 2220 of the connecting portion 22 contacts the second short-circuit detection contact pin top 1104 in the opposite direction of the Y-axis. In addition, if the connecting part 22 is installed on the upper end surface 111 of the contact pin holder along the opposite direction of the Y axis or the opposite direction of the X axis, the first abutting part 2210 of the connecting part 22 directly contacts the first short circuit detection contact pin top 11011 of the first short circuit detection contact pin 1101 in the second direction, and the second abutting part 2220 of the connecting part 22 directly contacts the second short circuit detection contact pin top 1104 of the second short circuit detection contact pin 1104 in the second direction, then there is no need to move the connecting part 22 along the opposite direction of the Y axis.

[0079] The connecting portion 22 of this embodiment is equivalent to the short-circuit detection terminal of the prior art, and can act as an electric bridge, so that the circuit between the two short-circuit detection pins of the printing device 1 is closed, and the short-circuit detection pins are electrically connected to the short-circuit detection mechanism, so that the short-circuit detection mechanism of the printing device 1 is also closed. Therefore, the printing device 1 can normally identify that the consumable chip 21 is correctly installed.

[0080] like Figure 5 As shown, the consumable box 2 includes a consumable box upper surface 201 and a consumable box front surface 202. Figure 6 After the consumable chip 21 is installed in the consumable cartridge 2, when the consumable cartridge 2 is installed in the printing device 1, the consumable cartridge front surface 202 faces the stylus holder front end surface 112. At this point, the consumable cartridge front surface 202 faces the direction opposite the X-axis, and the consumable cartridge upper surface 201 faces the Y-axis. The first abutment portion 2210 and the second abutment portion 2220 ensure stable installation with the stylus holder 11, preventing the consumable chip 21 from shifting upwards or downwards after the consumable cartridge 2 is installed in the printing device 1. This would cause the short-circuit detection terminal to deviate from the two short-circuit detection styluses, as in the prior art.

[0081] Example 2

[0082] like Figure 10-11 As shown, the structure of the connecting portion 22 of this embodiment is basically the same as that of the connecting portion 22 in Example 1, except that the first extension portion 221 is used to contact the side end 11015 of the first short-circuit detection pin, and the second extension portion 222 is used to contact the side end of the second short-circuit detection pin (not shown in the figure).

[0083] like Figure 10-11 As shown, the connecting portion 22 of this embodiment is obtained by rotating the connecting portion 22 of Example 1 90° from the Y-axis to the X-axis with the third direction as the rotation axis. At this time, the first extension portion 221 extends from the conductive portion 220 along the opposite direction of the X-axis, and the second end of the first extension portion 221 faces the opposite direction of the X-axis. The second extension portion 222 extends from the conductive portion 220 along the opposite direction of the X-axis, and the second end of the second extension portion 222 faces the opposite direction of the X-axis.

[0084] like Figure 10-11 As shown, the first extension portion 221 is used to contact the side end 11015 of the first short-circuit detection contact pin. Specifically, the first extension portion 221 includes a first abutting portion 2210, and the first abutting portion 2210 is hemispherical. The first extension portion 221 has a first side and a second side in the third direction. The first side of the first extension portion 221 faces the Z-axis direction, and the second side of the first extension portion 221 faces the opposite direction of the Z-axis. The first abutting portion 2210 is located on the first side of the first extension portion 221 in the third direction. The first abutting portion 2210 extends from the first extension portion 221 along the Z-axis direction. The first abutting portion 2210 is an elastic member, so that the first abutting portion 2210 is deformed in the third direction when contacting the side end 11015 of the first short-circuit detection contact pin, which can ensure close contact between the first abutting portion 2210 and the side end 11015 of the first short-circuit detection contact pin, thereby improving the conductive performance.

[0085] like Figure 10-11 As shown, the second extension portion 222 is used to contact the side end of the second short-circuit detection contact pin (not shown in the figure). Specifically, the second extension portion 222 includes a second abutting portion 2220, and the second abutting portion 2220 is hemispherical. The second abutting portion 2220 is arranged opposite to the first abutting portion 2210. The second extension portion 222 has a first side and a second side in the third direction. The first side of the second extension portion 222 faces the Z-axis direction, and the second side of the second extension portion 222 faces the opposite direction of the Z-axis. The second abutting portion 2220 is located on the second side of the second extension portion 222 in the third direction. The second abutting portion 2220 extends from the second extension portion 222 in the opposite direction of the Z-axis. The second abutting portion 2220 is an elastic member, so that the second abutting portion 2220 is deformed in the third direction when contacting the side end of the second short-circuit detection contact pin, which can ensure close contact between the second abutting portion 2220 and the side end of the second short-circuit detection contact pin, thereby improving the conductive performance.

[0086] like Figure 11 As shown, when the connecting portion 22 is electrically connected to the printing device 1, the connecting portion 22 is first installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, and then the connecting portion 22 is moved a certain distance along the opposite direction of the Y axis. The specific connection method is that when the connecting portion 22 is installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, the first abutting portion 2210 of the connecting portion 22 has a certain distance from the first short-circuit detection stylus side end 11015 of the first short-circuit detection stylus 1101 in the second direction, and the second abutting portion 2220 of the connecting portion 22 has a certain distance from the second short-circuit detection stylus side end (not shown in the figure) of the second short-circuit detection stylus 1104 in the second direction. Then, after the connecting part 22 is moved a certain distance in the opposite direction of the Y-axis, the first abutting part 2210 of the connecting part 22 successively exceeds the first short-circuit detection contact pin top 11011 and the first short-circuit detection contact pin front end 11012 of the first short-circuit detection contact pin 1101, and finally contacts the first short-circuit detection contact pin side end 11015 of the first short-circuit detection contact pin 1101 in the Z-axis direction, and the second abutting part 2220 of the connecting part 22 successively exceeds the second short-circuit detection contact pin top (not shown in the figure) and the second short-circuit detection contact pin front end (not shown in the figure) of the second short-circuit detection contact pin 1104, and finally contacts the second short-circuit detection contact pin side end of the second short-circuit detection contact pin 1104 in the opposite direction of the Z-axis. In addition, when the connecting portion 22 is electrically connected to the printing device 1, the connecting portion 22 can be directly aligned with the front end surface 112 of the stylus holder, and then the connecting portion 22 can be moved a certain distance in the opposite direction of the X axis, so that the first abutting portion 2210 of the connecting portion 22 is in direct contact with the first short-circuit detection stylus side end 11015 of the first short-circuit detection stylus 1101, and the second abutting portion 2220 of the connecting portion 22 is in direct contact with the second short-circuit detection stylus side end 1104 of the second short-circuit detection stylus 1104; if the connecting portion 22 is moved a certain distance in the opposite direction of the X axis, the first abutting portion 2210 of the connecting portion 22 is in direct contact with the second short-circuit detection stylus side end 11015 of the first short-circuit detection stylus 1101, and the second abutting portion 2220 of the connecting portion 22 is in direct contact with the second short-circuit detection stylus side end 1104 of the second short-circuit detection stylus There is still a certain distance between the first short-circuit detection contact pin side end 11015 of the first short-circuit detection contact pin 1101, and the second abutting portion 2200 of the connecting portion 22 is still a certain distance between the second short-circuit detection contact pin side end 1104 of the second short-circuit detection contact pin in the second direction. The connecting portion 22 can be moved a certain distance in the second direction to make the first abutting portion 2210 of the connecting portion 22 directly contact the first short-circuit detection contact pin side end 11015 of the first short-circuit detection contact pin 1101, and the second abutting portion 2220 of the connecting portion 22 is directly contacted with the second short-circuit detection contact pin side end 1104 of the second short-circuit detection contact pin. In order not to affect Figure 2The reset contact pin 1102 and the clock contact pin 1103 on the contact pin holder 11 of the printing device 1 are in contact with the reset terminal 212 and the clock terminal 213 of the first plane 2101, and a hole portion (not shown in the figure) is provided on the connecting portion 22 to expose the reset contact pin 1102 and the clock contact pin 1103.

[0087] The connecting portion 22 of this embodiment is equivalent to the short-circuit detection terminal of the prior art, and can act as an electric bridge, so that the circuit between the two short-circuit detection pins of the printing device 1 is closed, and the short-circuit detection pins are electrically connected to the short-circuit detection mechanism, so that the short-circuit detection mechanism of the printing device 1 is also closed. Therefore, the printing device 1 can normally identify that the consumable chip 21 is correctly installed.

[0088] like Figure 5 As shown, the consumable box 2 includes a consumable box upper surface 201 and a consumable box front surface 202. Figure 6 After the consumable chip 21 is installed in the consumable cartridge 2, when the consumable cartridge 2 is installed in the printing device 1, the consumable cartridge front surface 202 faces the stylus holder front end surface 112. At this point, the consumable cartridge front surface 202 faces the direction opposite the X-axis, and the consumable cartridge upper surface 201 faces the Y-axis. Compared to Example 1, the first abutting portion 2210 and the second abutting portion 2220 of this embodiment can better stabilize the two short-circuit detection styluses from both sides, preventing the consumable chip 21 from shifting upwards and downwards after the consumable cartridge 2 is installed in the printing device 1, which would cause the short-circuit detection terminal to deviate from the two short-circuit detection styluses in the prior art.

[0089] Example 3

[0090] like Figure 12-13As shown, the structure of the connecting portion 22 of this embodiment is basically the same as that of the connecting portion 22 in Example 1, except that the first extending portion 221 further includes a first fixing portion, and the second extending portion 222 further includes a second fixing portion. When the first abutting portion 2210 of the first extending portion 221 contacts the top end 11011 of the first short-circuit detection stylus, the first fixing portion is used to cooperate with the first matching portion of the stylus holder 11 to fix the first extending portion 221 to the printing device 1; when the second abutting portion 2220 of the second extending portion 222 contacts the top end of the second short-circuit detection stylus (not shown in the figure), the second fixing portion is used to cooperate with the second matching portion of the stylus holder 11 to fix the second extending portion 222 to the printing device 1. Since the first fixed portion and the second fixed portion cooperate with the first matching portion and the second matching portion respectively, the first abutting portion 2210 and the second abutting portion 2220 can be in close contact with the first short-circuit detection contact pin top 11011 and the second short-circuit detection contact pin top respectively, thereby improving the conductive performance. Therefore, for the first abutting portion 2210 and the second abutting portion 2220, one way is that the first abutting portion 2210 and the second abutting portion 2220 are elastic parts, which are elastic and can be deformed in the second direction; another way is that the first abutting portion 2210 and the second abutting portion 2220 are rigid parts, which are rigid.

[0091] like Figure 12-13 As shown, the first fixing portion includes a first embedded portion 223 and a second embedded portion 224, the first extension portion 221 has a first side and a second side in the third direction, the first side of the first extension portion 221 faces the Z-axis direction, and the second side of the first extension portion 221 faces the opposite direction of the Z-axis, the first embedded portion 223 is located on the second side of the first extension portion 221 in the third direction, the first end of the first embedded portion 223 is connected to the first extension portion 221, the second end of the first embedded portion 223 extends in the opposite direction of the Y-axis, and the second end of the first embedded portion 223 and the first extension portion 221 have a certain distance in the third direction; the second embedded portion 224 is located on the first side of the first extension portion 221 in the third direction, the first end of the second embedded portion 224 is connected to the first extension portion 221, the second end of the second embedded portion 224 extends in the opposite direction of the Y-axis, and the second end of the second embedded portion 224 and the first extension portion 221 have a certain distance in the third direction. The first mating portion includes a first gap 1111 and a second gap 1112, the first embedded portion 223 is used to be embedded in the first gap 1111, and the second embedded portion 224 is used to be embedded in the second gap 1112, so that the first extension portion 221 is fixed to the printing device 1, wherein the first embedded portion 223 and the second embedded portion 224 can be non-conductive parts made of non-conductive materials.

[0092] like Figure 12-13As shown, the second fixing portion includes a third embedded portion 225 and a fourth embedded portion 226, the second extension portion 222 has a first side and a second side in the third direction, the first side of the second extension portion 222 faces the Z-axis direction, and the second side of the second extension portion 222 faces the opposite direction of the Z-axis, the third embedded portion 225 is located on the second side of the second extension portion 222 in the third direction, the first end of the third embedded portion 225 is connected to the second extension portion 222, the second end of the third embedded portion 225 extends in the opposite direction of the Y-axis, and the second end of the third embedded portion 225 and the second extension portion 222 have a certain distance in the third direction; the fourth embedded portion 226 is located on the first side of the second extension portion 222 in the third direction, the first end of the fourth embedded portion 226 is connected to the second extension portion 222, the second end of the fourth embedded portion 226 extends in the opposite direction of the Y-axis, and the second end of the fourth embedded portion 226 and the second extension portion 222 have a certain distance in the third direction. The second mating portion includes a third gap 1113 and a fourth gap 1114, the third embedded portion 225 is used to be embedded in the third gap 1113, and the fourth embedded portion 226 is used to be embedded in the fourth gap 1114, so that the second extension portion 222 is fixed to the printing device 1, wherein the third embedded portion 225 and the fourth embedded portion 226 can be non-conductive parts made of non-conductive materials.

[0093] like Figure 13As shown, when the connecting portion 22 is electrically connected to the printing device 1, the connecting portion 22 is first installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, and then the connecting portion 22 is moved a certain distance along the opposite direction of the Y axis. The specific connection method is that when the connecting portion 22 is installed on the upper end surface 111 of the stylus holder along the opposite direction of the Y axis or the opposite direction of the X axis, the first abutting portion 2210 of the connecting portion 22 is at a certain distance from the first short-circuit detection stylus tip 11011 of the first short-circuit detection stylus 1101 in the second direction, and the first embedding portion 223 and the second embedding portion 224 of the connecting portion 22 are respectively embedded in the first slit 1111 and the second slit 1112 of the stylus holder 11, so as to fix the first extension portion 221 from both ends; the connecting portion 22 The second abutting portion 2220 of the connecting portion 22 is at a certain distance from the second short-circuit detection contact pin tip 1104 (not shown in the figure) in the second direction, and the third embedding portion 225 and the fourth embedding portion 226 of the connecting portion 22 are respectively embedded in the third slit 1113 and the fourth slit 1114 of the contact pin holder 11, so as to fix the second extending portion 222 from both ends; then, after the connecting portion 22 is moved a certain distance in the opposite direction of the Y-axis, the first abutting portion 2210 of the connecting portion 22 is in contact with the first short-circuit detection contact pin tip 11011 of the first short-circuit detection contact pin 1101 in the opposite direction of the Y-axis, and the second abutting portion 2220 of the connecting portion 22 is in contact with the second short-circuit detection contact pin tip 1104 in the opposite direction of the Y-axis. In addition, if the connecting part 22 is installed on the upper end surface 111 of the contact pin holder along the opposite direction of the Y axis or the opposite direction of the X axis, the first abutting part 2210 of the connecting part 22 directly contacts the first short circuit detection contact pin top 11011 of the first short circuit detection contact pin 1101 in the second direction, and the second abutting part 2220 of the connecting part 22 directly contacts the second short circuit detection contact pin top 1104 of the second short circuit detection contact pin 1104 in the second direction, then there is no need to move the connecting part 22 along the opposite direction of the Y axis.

[0094] In the second direction, the length of the first extending portion 221 is smaller than the length of the first embedded portion 223 or the length of the second embedded portion 224 ; in the second direction, the length of the second extending portion 222 is smaller than the length of the third embedded portion 225 or the length of the fourth embedded portion 226 .

[0095] The connecting portion 22 of this embodiment is equivalent to the short-circuit detection terminal of the prior art, and can act as an electric bridge, so that the circuit between the two short-circuit detection pins of the printing device 1 is closed, and the short-circuit detection pins are electrically connected to the short-circuit detection mechanism, so that the short-circuit detection mechanism of the printing device 1 is also closed. Therefore, the printing device 1 can normally identify that the consumable chip 21 is correctly installed.

[0096] like Figure 5As shown, the consumable box 2 includes a consumable box upper surface 201 and a consumable box front surface 202. Figure 6 After the consumable chip 21 is installed in the consumable cartridge 2, when the consumable cartridge 2 is installed in the printing device 1, the front surface 202 of the consumable cartridge faces the front end surface 112 of the stylus holder. At this time, the front surface 202 of the consumable cartridge faces the direction opposite to the X-axis, and the upper surface 201 of the consumable cartridge faces the Y-axis. The first and second embedded portions 223 and 224 of the connecting portion 22 respectively embed into the first and second slits 1111 and 1112 of the stylus holder 11, securing the first extension 221 from both ends. The third and fourth embedded portions 225 and 226 of the connecting portion 22 respectively embed into the third and fourth slits 1113 and 1114 of the stylus holder 11, securing the second extension 222 from both ends. The first and second extensions 221 and 222 ensure stable installation with the stylus holder 11, preventing the consumable chip 21 from shifting upwards and to the sides after the consumable cartridge 2 is installed in the printing device 1. This would cause the short-circuit detection terminal to deviate from the two short-circuit detection styluses in the prior art.

[0097] Example 4

[0098] like Figure 14 As shown, the connection portion 22 of this embodiment is a variation of Example 3 and has a substantially identical structure to the connection portion 22 in Example 3, except that the connection portion 22 further includes a hollow portion, which includes a first hollow portion 227, a second hollow portion 228, a third hollow portion 229, and a fourth hollow portion 230 located on the conductive portion 220. Furthermore, other embodiments may also include at least one of the aforementioned hollow portions.

[0099] like Figure 14As shown, the first hollow portion 227 is located between the first embedded portion 223 and the second embedded portion 224 in the third direction, and the first hollow portion 227 is connected to at least a portion of the first extension portion 221; the second hollow portion 228 is located between the third embedded portion 225 and the fourth embedded portion 226 in the third direction, and the second hollow portion 228 is connected to at least a portion of the second extension portion 222; the third hollow portion 229 is located between the second embedded portion 224 and the third embedded portion 225 in the third direction, and the third hollow portion 229 passes through the conductive portion 220 in the X-axis direction; the fourth hollow portion 230 is located between the second embedded portion 224 and the third embedded portion 225 in the third direction, and the fourth hollow portion 230 passes through the conductive portion 220 in the opposite direction of the X-axis. The first hollow portion 227, the second hollow portion 228, the third hollow portion 229 and the fourth hollow portion 230 can effectively reduce the material cost of the connecting portion 22. In addition, the first hollow portion 227, the second hollow portion 228, the third hollow portion 229 and the fourth hollow portion 230 can also serve as force-bearing portions, and the force-bearing portions are used as force points to clamp the connecting portion 22 so that the connecting portion 22 can be installed on or removed from the printing device 1.

[0100] like Figure 14 As shown, the first embedded portion 223 is located on the second side of the first extension portion 221 in the third direction, and the second embedded portion 224 is located on the first side of the first extension portion 221 in the third direction. In the second direction, the length L3 of the first extension portion 221 is less than the length L1 of the first embedded portion 223 or the length L2 of the second embedded portion 224. The third embedded portion 225 is located on the second side of the second extension portion 222 in the third direction, and the fourth embedded portion 226 is located on the first side of the second extension portion 222 in the third direction. Similarly, in the second direction, the length of the second extension portion 222 is less than the length of the fourth embedded portion 226 and the length of the third embedded portion 225. This ensures that the first extension portion 221 and the second extension portion 222 of the connecting portion 22 can be stably mounted on the stylus holder 11.

[0101] The specific connection method of the connection portion 22 of this embodiment can be referred to in Example 3, so it will not be repeated here.

[0102] Example 5

[0103] like Figure 15-16As shown, the connecting portion 22 of this embodiment is fixed on the consumable box 2, the consumable box 2 is installed with the consumable chip 21, the consumable box 2 is detachably installed on the printing device 1, and the connecting portion 22 is detachably installed on the printing device 1 along with the consumable box 2. When the consumable box 2 is installed on the printing device 1, the connecting portion 22 is used to connect the first short-circuit detection contact pin 1101 and the second short-circuit detection contact pin 1101 on the contact pin holder 11 of the printing device 1, so that an electrical connection is formed between the first short-circuit detection contact pin 1101 and the second short-circuit detection contact pin 1101; each terminal of the consumable chip 21 contacts the corresponding contact pin on the contact pin holder 11 of the printing device 1 to form an electrical connection.

[0104] like Figure 15-16 As shown, the consumable box 2 includes a consumable box top surface 201 and a consumable box front surface 202. The consumable box top surface 201 faces the Y-axis direction, the consumable box front surface 202 is connected to the consumable box top surface 201, and the consumable box front surface 202 faces the direction opposite to the X-axis. The consumable box 2 is installed in the direction opposite to the X-axis, and the consumable box 2 is removed in the X-axis direction. The consumable chip 21 is installed on the consumable box front surface 202 of the consumable box 2, and the connecting portion 22 is fixed to the consumable box front surface 202 of the consumable box 2. In the second direction, the connecting portion 22 is closer to the consumable box top surface 201 than the consumable chip 21.

[0105] like Figure 15-17As shown, the connecting portion 22 includes a conductive portion 220, a first extension portion 221, a second extension portion 222 and a mounting portion 240; the conductive portion 220 extends along the third direction, and the two ends of the conductive portion 220 in the third direction are electrically connected to the first extension portion 221 and the second extension portion 222 respectively, so that an electrical connection is formed between the second extension portion 222 and the first extension portion 221; the first extension portion 221 is extended from the conductive portion 220 along the opposite direction of the X-axis. Specifically, the first extension portion 221 has a first end and a second end in the first direction, the first end of the first extension portion 221 is connected to the conductive portion 220 in the X-axis direction, the second end of the first extension portion 221 faces the opposite direction of the X-axis, and the second end of the first extension portion 221 has a first inclined surface 2211 in the opposite direction of the Y-axis. The first inclined surface 2211 has a first end and a second end in the first direction, and the first end of the first inclined surface 2211 is relatively closer to the first inclined surface in the first direction. The second end of a slope 2211 is closer to the conductive part 220, and the first end of the first slope 2211 is closer to the consumable chip 21 in the second direction than the second end of the first slope 2211; the second extension portion 222 extends in the opposite direction of the X-axis. Specifically, the second extension portion 222 has a first end and a second end in the first direction, the first end of the second extension portion 222 is connected to the conductive part 220 in the X-axis direction, the second end of the second extension portion 222 faces in the opposite direction of the X-axis, and the second end of the second extension portion 222 has a second slope 2221 in the opposite direction of the Y-axis. The first slope 2221 has a first end and a second end in the first direction, the first end of the second slope 2221 is closer to the conductive part 220 in the first direction than the second end of the second slope 2221, and the first end of the second slope 2221 is closer to the consumable chip 21 in the second direction than the second end of the second slope 2221.

[0106] like Figure 15-17As shown, the mounting portion 240 is located on the conductive portion 220 and is mounted on the front surface 202 of the consumable box in the X-axis direction so that the connecting portion 22 is mounted on the consumable box 2. Specifically, the mounting portion 240 includes a snap-fitting portion that can snap-fit ​​onto the front end surface 202 of the consumable box so that the mounting portion 240 is mounted on the front end surface 202 of the consumable box. The snap-fitting portion includes a protruding snap-fitting structure that is embedded in or welded to the front end surface 202 of the consumable box, or snap-fitted through a positioning hole on the front end surface 202 of the consumable box. In addition, the mounting portion 240 can also be connected to the first extension portion 221 and the second extension portion 222. Since the connecting portion 22 is fixed on the consumable box 2, when the consumable box 2 is installed on the printing device 1, when the printing device 1 fixes the consumable box 2, the connecting portion 22 is indirectly fixed through the consumable box 2, so that the first extension portion 221 and the second extension portion 222 can be in close contact with the first short-circuit detection contact pin top 11011 and the second short-circuit detection contact pin top, respectively, thereby improving the conductive performance. Therefore, for the first extension portion 221 and the second extension portion 222, one way is that the first extension portion 221 and the second extension portion 222 are elastic parts, which are elastic and can be deformed in the second direction; another way is that the first extension portion 221 and the second extension portion 222 are rigid parts, which are rigid.

[0107] After the consumable box 2 is installed on the printing device 1 in the opposite direction of the X-axis, the connecting portion 22 contacts the upper end surface 111 of the stylus holder. The specific contact method is that the first inclined surface 2211 of the first extension portion 221 contacts the first short-circuit detection stylus top 11011 of the first short-circuit detection stylus 1101 in the opposite direction of the Y-axis, and the second inclined surface 2221 of the second extension portion 222 contacts the second short-circuit detection stylus top (not shown in the figure) of the second short-circuit detection stylus 1104 in the opposite direction of the Y-axis, so that the first extension portion 221 is in electrical contact with the first short-circuit detection stylus 1101, and the second extension portion 222 is in electrical contact with the second short-circuit detection stylus 1104.

[0108] The connecting portion 22 of this embodiment is equivalent to the short-circuit detection terminal of the prior art, and can act as an electric bridge, so that the circuit between the two short-circuit detection pins of the printing device 1 is closed, and the short-circuit detection pins are electrically connected to the short-circuit detection mechanism, so that the short-circuit detection mechanism of the printing device 1 is also closed. Therefore, the printing device 1 can normally identify that the consumable chip 21 is correctly installed.

[0109] Example 6

[0110] like Figure 18-19As shown, compared with Example 5, the connection portion 22 fixed to the consumables box 2 of this embodiment has another implementation method, that is, the connection portion 22 in Example 5 is replaced with the connection portion 22 in Example 3, and the mounting portion 240 in Example 5 is provided on the basis of the connection portion 22 in Example 3 to mount the connection portion 22 on the consumables box 2. For the specific structure of the connection portion 22, please refer to Example 3, so it will not be repeated here. For the specific structure of the mounting portion 240, please refer to Example 5, so it will not be repeated here.

[0111] After the consumables box 2 is installed on the printing device 1 in the opposite direction of the X-axis, the connecting portion 22 contacts the upper end surface 111 of the stylus holder. Specifically, the first abutting portion 2210 of the connecting portion 22 contacts the first short-circuit detection stylus tip 11011 of the first short-circuit detection stylus 1101, and the second abutting portion 2220 of the connecting portion 22 contacts the second short-circuit detection stylus tip (not shown in the figure) of the second short-circuit detection stylus 1104; the first embedding portion 223 and the second embedding portion 224 of the connecting portion 22 are respectively embedded in the first slit 1111 and the second slit 1112 of the stylus holder 11, and can fix the first extension portion 221 from both ends; the third embedding portion 225 and the fourth embedding portion 226 of the connecting portion 22 are respectively embedded in the third slit 1113 and the fourth slit 1114 of the stylus holder 11, and can fix the second extension portion 222 from both ends.

[0112] The consumables box 2 includes a consumables box upper surface 201 and a consumables box front surface 202. Figure 6 After the consumable chip 21 is installed in the consumable box 2, when the consumable box 2 is installed in the printing device 1, the consumable box front surface 202 faces the front end surface 112 of the stylus holder. At this time, the consumable box front surface 202 faces the direction opposite to the X-axis, and the consumable box upper surface 201 faces the Y-axis. Because the first embedding portion 223 and the second embedding portion 224 of the connecting portion 22 respectively embed into the first slit 1111 and the second slit 1112 of the stylus holder 11, they can fix the first extension portion 221 from both ends. The third embedding portion 225 and the fourth embedding portion 226 of the connecting portion 22 respectively embed into the third slit 1113 and the fourth slit 1114 of the stylus holder 11, they can fix the second extension portion 222 from both ends. The first extension portion 221 and the second extension portion 222 can stably mount to the stylus holder 11, preventing the consumable chip 21 from shifting to the upper sides after the consumable box 2 is installed in the printing device 1, which would cause the short-circuit detection terminal to deviate from the two short-circuit detection styluses in the prior art. In addition, since the connecting portion 22 is fixed to the consumable box 2 , when the consumable box 2 is installed in the printing device 1 , the connecting portion 22 can also play a role in fixing the consumable box 2 .
