Description

[0001] This application claims priority to the Chinese patent application No. 202411389575.7, filed on September 30, 2024, entitled "A consumable chip, a consumable cartridge and a printing device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of printing equipment, in particular to a consumable chip, a consumable cartridge and a printing device. BACKGROUND

[0003] In the process of printing imaging, the printing device needs the imaging auxiliary information of the consumable cartridge to complete the imaging process. The imaging auxiliary information of the printing device is recorded not only in the printing device but also in the consumable chip of the consumable cartridge. The consumable cartridge can be an ink cartridge filled with ink or a toner cartridge filled with toner. The function of the consumable chip is to control the authentication and data matching between the consumable cartridge and the printing device, and to provide imaging auxiliary information in the subsequent imaging process. The consumable chip is provided with a processing unit and a terminal for electrical connection. The information stored in the processing unit includes but is not limited to toner amount information, manufacturer information, manufacturing date, color of material (such as ink, toner), capacity of material, remaining or consumed amount of material, printable page number, printed page number, authentication data, etc. The authentication data can include one or more of consumable chip serial number, toner serial number, ink serial number, digital signature, seed data or verification data.

[0004] However, in the prior art, the consumable cartridge is detachably assembled on the carriage. During the printing driving process of the printing device, the carriage reciprocally moves. Due to the detachable connection relationship, there is a possibility of unstable connection, which may cause the position between the consumable chip and the connecting contact pin in the carriage to deviate. When the position between the consumable chip and the connecting contact pin deviates, the ground terminal on the consumable chip may not be able to contact the ground contact pin, resulting in unstable grounding of the consumable chip. SUMMARY

[0005] The present application provides a consumable chip, a consumable cartridge and a printing device, which are used to solve the problem of poor electrical connection stability of the ground terminal.

[0006] The present application provides a consumable chip, which can be installed in a consumable cartridge, and the consumable cartridge can be installed in a printing device. The consumable chip includes a connecting terminal, and the connecting terminal includes at least one first connecting terminal. The first connecting terminal is electrically connected to a grounding component through a connecting piece. The grounding component is located in an area outside the consumable chip on the consumable cartridge and is not electrically connected to the connecting contact pin on the printing device.

[0007] As a specific embodiment, the consumable box comprises an ink storage bin storing ink; the ink in the ink storage bin is grounded; one end of the connecting member is electrically connected with the first connecting terminal, and the other end of the connecting member is in contact with the ink in the ink storage bin.

[0008] Further, one end of the connecting member is fixedly arranged on the surface of the consumable chip, or one end of the connecting member is embedded in the interior of the consumable chip, or the connecting member is fixedly mounted on the ink storage bin.

[0009] As another specific embodiment, the consumable box comprises a housing; the grounding component is arranged on the housing.

[0010] Further, one end of the connecting member is fixedly arranged on the surface of the consumable chip, or one end of the connecting member is embedded in the interior of the consumable chip.

[0011] As a specific embodiment, the grounding component is a second connecting member arranged on the housing; the printing device further comprises a carriage for assembling the consumable box, and the carriage comprises a screw; when the consumable box is assembled on the carriage, the second connecting member is in contact with the screw.

[0012] As a specific embodiment, the housing of the consumable box is made of conductive material; the first connecting terminal is arranged on the region of the consumable chip in contact with the housing; the connecting terminal further comprises at least one second connecting terminal; the second connecting terminal does not comprise a grounding terminal; and the second connecting terminal is located on the region of the consumable chip not in contact with the housing.

[0013] Further, the printing device further comprises a carriage; the carriage is provided with a second conductive part; and the grounding component is grounded by being in contact with the second conductive part.

[0014] Further, the connecting terminal further comprises at least one second connecting terminal; one side of the consumable chip is a first contact surface, and the second connecting terminal is located on the first contact surface, and the first connecting terminal is located on the region outside the first contact surface.

[0015] As a specific embodiment, the consumable chip further has a second contact surface; the second contact surface and the first contact surface are located on opposite sides of the consumable chip; and the first connecting terminal is located on the second contact surface.

[0016] The application further provides a consumable box comprising the consumable chip.

[0017] The application further provides a printing device comprising the consumable box.

[0018] Beneficial effects:

[0019] Compared with the prior art, the consumable chip is grounded through the grounding terminal and the grounding contact pin. The consumable chip provided in the present application is grounded through the connecting piece and the grounding component on the consumable cartridge. The connection relationship is more stable. Even if the position of the consumable chip deviates, the first connecting terminal on the consumable chip can still be grounded through the connecting piece. The problem that the grounding terminal cannot stably contact the printing device when the consumable cartridge is installed in the printing device, and the consumable chip cannot be grounded or cannot be stably grounded due to the deviation of the consumable chip can be solved. At the same time, compared with the case where the grounding component is located on the shell and the connecting piece deforms during the movement of the carriage with the consumable cartridge relative to the shell, the connection between the first connecting terminal and the grounding component can be unstable. The grounding component provided in the present application is located on the consumable cartridge. Even if the carriage moves with the consumable cartridge relative to the shell, the grounding component will move with the consumable cartridge and will not deform due to the movement of the consumable cartridge. The first connecting terminal and the grounding component can be stably connected to ensure the grounding stability of the first connecting terminal. Further, compared with the case where the connecting piece is electrically connected to the grounding contact pin in the carriage, the area for electrical connection of the grounding contact pin is small, which can cause unstable connection between the connecting piece and the grounding contact pin, and increase the possibility that the consumable chip will pull the connecting piece away from the grounding contact pin under the action of inertia when the carriage moves back and forth, and the consumable chip cannot be grounded. The grounding component provided in the present application is located on the consumable cartridge outside the region of the consumable chip and is not electrically connected to the connecting contact pin. The area of the grounding component can be larger than that of the connecting contact pin, so that the connection between the connecting piece and the grounding component can be more stable, and the grounding component will move with the consumable cartridge, further reducing the possibility that the connecting piece will be disconnected from the grounding component.

[0032] For better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0033] It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0034] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0035] It should be understood that the term "and / or" used herein only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0036] It should be noted that the "upper", "lower", "left", "right" and other orientation words described in the embodiments of the present application are described in the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, it should also be understood in the context that when referring to one element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0037] As shown in Figure 1 , the printing device includes a housing 1 having a signal end 11, a carriage 2 mounted on the housing 1, and a consumable cartridge 3 mounted on the carriage 2. The carriage 2 can be mounted on the housing 1 through a guide rail 15 and can move relative to the housing 1. When the carriage 2 drives the consumable cartridge 3 to move relative to the housing 1, the conductive part 12 can be deformed, Figure 1 , the conductive part 12 in the signal end 11 obtains the signal provided by the printing device.

[0038] As shown in Figure 1 , 2, 6 and 8, the present application provides a consumable chip 31, which can be mounted on the consumable cartridge 3, and the consumable cartridge 3 is detachably mounted on the printing device; wherein the consumable chip 31 comprises a connection terminal; the connection terminal comprises at least one first connection terminal 311; the first connection terminal 311 is electrically connected to the grounding part through the connecting piece; the grounding part is located in the area of the consumable cartridge 3 outside the consumable chip 31, and is not electrically connected with the connecting contact pin 131 on the printing device.

[0039] Compared with the prior art, the consumable chip is grounded by the grounding terminal and the grounding contact pin, the consumable chip 31 provided by the present application is electrically connected to the grounding part located on the consumable cartridge 31 through the connecting piece, and the connection relationship is more stable. Even if the position of the consumable chip 31 deviates compared with the position of the connecting contact pin 131, the first connection terminal 311 on the consumable chip 31 can still be grounded through the connecting piece, which can solve the problem that in the prior art, when the consumable cartridge is mounted on the printing device, the position of the consumable chip deviates due to the reciprocating movement of the carriage, which causes the grounding terminal to be unstable in contact with the printing device, and the consumable chip cannot be grounded or the grounding is unstable.

[0040] At the same time, compared with the grounding part located on the housing 31, the connecting piece deforms during the process that the carriage 2 drives the consumable cartridge 3 to move relative to the housing 1, which may cause the connection between the first connection terminal 311 and the grounding part to be unstable. The grounding part provided by the present application is located on the consumable cartridge 31, so that even if the carriage 2 drives the consumable cartridge 3 to move relative to the housing 1, the grounding part will move together with the consumable cartridge 3 and will not deform due to the movement of the consumable cartridge 3. The first connection terminal 311 and the grounding part can be stably connected, and the grounding stability of the first connection terminal 311 is ensured.

[0041] Embodiment 1

[0042] As shown in Figure 2 , 6, the present embodiment provides a consumable chip 31, which can be installed in a consumable cartridge 3, and the consumable cartridge 3 is detachably installed in a printing device. The consumable chip 31 comprises a connection terminal; the connection terminal comprises at least one first connection terminal 311. The consumable cartridge 3 further comprises an ink storage 32 and an ink outlet 33, wherein the ink storage 32 stores ink 321, and the ink 321 in the ink storage 32 is grounded; in the present embodiment, the grounding component is the ink 321 in the ink storage 32; the connecting piece is the first connecting piece 14 in Figure 2 ; one end of the first connecting piece 14 is electrically connected with the first connection terminal 311, and the other end is in contact with the ink 321 in the ink storage 32.

[0043] As shown in Figure 3 , the carriage 2 comprises a conductive piece 13 and an ink receiving port 21 for cooperating with the ink outlet 33 of the consumable cartridge 3. Figure 3 The ink receiving port 21 in is a second conductive part; after the consumable cartridge 3 is installed in the carriage 2, the ink 321 flows out of the ink outlet 33 and is transmitted to the ink receiving port 21 on the carriage 2, and the ink receiving port 21 can form an electrical connection with the signal terminal 11 of the housing 1, and the ink 321 has electrical conductivity, thereby forming a current loop to form a grounding loop, and the ink 321 is grounded through the ink receiving port 21, that is, the grounding component (ink 321 in the present embodiment) is grounded by contacting the second conductive part (ink receiving port 21 in the present embodiment).

[0044] In some preferred embodiments, when the ink 321 in the ink storage 32 enters the printing head for ejection, it contacts a grounding signal on the printing head inside the printing head to release static electricity in the ink, so that the conductive ink has the possibility to provide a grounding signal.

[0045] In the present embodiment, the printing device can comprise a plurality of signal terminals 11, which can be a metal back plate or a metal bottom plate at a paper outlet position of the printing device. The ink receiving port 21 can also form an electrical connection with the signal terminal 11 of the housing 1. The ink 321 inside can form a grounding signal.

[0046] Figure 5 As shown in Figure 4 , the connection terminal in the consumable chip 31 further comprises at least one second connection terminal 312; the consumable chip 31 further comprises a processing unit 315; the connection terminal is electrically connected with the processing unit 315 to transmit signals between the consumable chip 31 and the printing device. Figure 5The second connection terminal 312 of the consumable chip 31 is electrically connected to the first connection terminal 311. The consumable chip 31 has a first contact surface 313 on one side, and the second connection terminal 312 is arranged on the first contact surface 313. The second connection terminal 312 does not include a ground terminal, and the first connection terminal 311 is arranged on an area other than the first contact surface 313. The consumable chip 31 includes a second contact surface 314, and the first contact surface 313 and the second contact surface 314 are located on opposite sides of the consumable chip 31. The first connection terminal 311 is located on the second contact surface 314. Preferably, a processing unit 315 is arranged on the second contact surface 314. As shown in Figure 5 In a possible implementation, the second connection terminal 312 includes a data terminal 312a, a clock terminal 312b, a power terminal 312c, and a chip selection terminal 312d. Each second connection terminal is connected to the processing unit 315 through a respective via.

[0047] As shown in Figure 4 The connection contact pins 131 (including ground contact pins) located in the carriage 2 are arranged to have protruding end portions for electrical connection. The area of the protruding end portions is small. Compared with electrical connection of the ground contact pins through the connecting member, the small area of the ground contact pins for electrical connection may cause unstable connection of the connecting member with the ground contact pins, and increase the possibility that the connecting member is pulled away from the ground contact pins under the action of inertia when the carriage moves back and forth, and the consumable chip cannot be grounded. The grounding member provided in the present application is arranged on the consumable chip 31 of the consumable cartridge 3 and is not electrically connected to the connection contact pins. The area of the grounding member is larger than that of the connection contact pins, so that the connecting member can be more stably connected to the grounding member. Moreover, the grounding member moves together with the consumable cartridge 3, which further reduces the possibility that the connecting member is pulled away from the grounding member.

[0048] As shown in Figure 6 The first connection terminal 311 of the consumable chip 31 is electrically connected to the first connecting member 14. In a possible implementation, the consumable chip 31 includes the first connecting member 14, and one end of the first connecting member 14 is fixedly arranged on the surface of the consumable chip 31 (i.e., one end of the first connecting member 14 in the Figure 5 and Figure 6 When the consumable chip 31 is installed in the consumable cartridge 3, the first connecting member 14 enters the ink storage chamber 32 through the through hole (not shown in the figure) of the consumable cartridge 3 and is in contact with the ink 321 in the ink storage chamber 32. The first connection terminal 311 is electrically connected to the circuit ground point of the consumable chip 31, so that the connecting member is electrically connected to the circuit ground point of the consumable chip 31 and is in contact with the ink 321, thereby forming a ground loop between the circuit ground point and the ink.

[0049] Preferably, the first connecting member 14 is made of corrosion-resistant material (such as silver-plated or gold-plated wire) to ensure that it is not easily oxidized in the ink environment.

[0050] Preferably, the processing unit 315 is an electronic module, or a single-chip microcomputer or a wafer, which can realize the functions of the storage module and the signal processing module.

[0051] Preferably, as shown in FIG. 3, the processing unit 315 includes a storage module 3151 and a signal processing module 3152. The storage module 3151 is used to store relevant information, and the processing unit 315 includes a circuit grounding point. The signal processing module 3152 can process the grounding signal obtained from the ink 321 to ensure the stability and reliability of the signal. Figure 7

[0052] In another possible implementation, the first connecting member 14 is not fixed on the consumable chip 31 but is fixed on the ink storage chamber 32 and thus contacts the ink 321, i.e., the connecting member is fixedly installed on the ink storage chamber 32. The first connecting member can be exposed through a through hole (not shown in the figure) of the consumable cartridge 3, i.e., one end of the connecting member enters the ink storage chamber 32 to contact the ink 321, and the other end extends out of the ink storage chamber 32 and is exposed through the through hole of the consumable cartridge 3. When the consumable cartridge 3 is installed on the carriage 2, the first connecting terminal 311 of the consumable chip 31 installed on the consumable cartridge 3 contacts the first connecting member 14 to form a grounding loop.

[0053] In one possible implementation, the first connecting terminal 311 is located inside the consumable chip 31. By embedding the first connecting terminal 311 inside the consumable chip 31, the space occupied by the first connecting terminal 311 on the surface of the consumable chip 31 can be reduced, the structure of the consumable chip 31 can be optimized, and the consumable chip 31 can have more area for electrical connection. The first connecting member 14 can be pre-embedded inside the consumable chip 31 when the consumable chip 31 is processed and electrically connected to the first connecting terminal 311, i.e., one end of the connecting member is embedded inside the consumable chip 32.

[0054] Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that the first connecting terminal 311 and the second connecting terminal 312 can be on the same contact surface. In one possible implementation, the first connecting terminal 311 does not contact one of the connecting contact pins 131 for providing a grounding signal, and the first connecting terminal 311 is electrically connected to the connecting member to form a grounding loop.

[0056] Embodiment 3

[0057] As shown in FIG. 4, the first connecting terminal 311 is electrically connected to the first connecting member 14 to form a grounding loop. Figure 8 ​As shown, the embodiment of the present application provides a consumable chip 31, which can be installed in a consumable cartridge 3, and the consumable cartridge 3 is detachably installed in a printing device. The consumable chip 31 comprises a connection terminal, and the connection terminal comprises at least one first connection terminal 311. The consumable cartridge 3 further comprises an ink storage 32, an ink inlet 33 and a housing, wherein the ink storage 32 stores ink 321; and the consumable cartridge 3 further comprises a second connecting piece 142, and specifically, the second connecting piece 142 can be arranged on the housing of the consumable cartridge 3, and the specific position is not limited.

[0058] Figure 3 The third conductive part 121 on the carriage 2 can obtain the ground signal provided by the printing device from the signal terminal 11, and specifically, the third conductive part 121 can be a screw on the carriage 2, and the screw can be used to fix the components on the carriage 2, such as a metal plate. It can be understood that in order to eliminate static electricity on the whole machine device and reduce the safety risk caused by equipment leakage, the ground signal is often arranged on the shell, the bulk metal plate and the metal connecting piece in the electronic equipment. In some printing devices, in order to connect the ground terminal on the circuit board with the ground reference point of the equipment, a conductive material is arranged at the screw hole of the circuit board, so that when the circuit board is fixed by the screw, the ground signal is connected to the ground reference point of the whole machine through the screw. The screw adopted by the third conductive part 121 in the embodiment is at least one screw through which the ground signal is connected to the ground reference point of the whole machine.

[0059] When the consumable box 3 is installed on the printhead 2, the second connector 142 contacts the third conductive part 121. In this embodiment, the second connector 142 is a grounding component; the third conductive part 121 is the second conductive part on the printhead 2; the second connector 142 is grounded through the third conductive part 121; the first connecting terminal 311 is electrically connected to the second connector 142 for grounding; that is, the grounding component is grounded through contact with the second conductive part. The second connector 142 is electrically connected to the circuit grounding point in the consumable chip 31. Specifically, if the distance between the second connector 142 and the consumable chip 31 is relatively far, it can be electrically connected to the consumable chip 31 through a wire, that is, the first connecting terminal 311 is electrically connected to the second connector 142 through a connector (i.e., a wire); one end of the connector is electrically connected to the first connecting terminal 311, and the other end is electrically connected to the second connector 142; in another embodiment, the first connecting terminal 311 may also be connected to the second connector 142 without a wire. 2. Electrical connection; The outer shell of the consumable box 3 is made of conductive material. When the second connector 142 contacts the third conductive part 121, the second connector 142 can be electrically connected to the consumable chip 31, thereby forming an electrical connection between the third conductive part 121 and the circuit grounding point in the consumable chip 31. That is, the first connection terminal 311 is electrically connected to the second connector 142 through the connector (i.e., the outer shell of the consumable box 3); one end of the connector (i.e., the outer shell of the consumable box 3) is electrically connected to the first connection terminal 311, and the other end is electrically connected to the second connector 142.

[0060] Specifically, when the outer shell of the consumable box 3 is made of conductive material, the circuit grounding point of the consumable chip 31 is located in the area of ​​the consumable chip 31 that contacts the outer shell of the consumable box 3; the second connection terminal of the consumable chip 31 is located in the area of ​​the consumable chip 31 that does not contact the outer shell of the consumable box 3. For example... Figure 5 , 6 As shown, the connection terminal in the consumable chip 31 also includes at least one second connection terminal 312; the consumable chip 31 also includes a processing unit 315, and the connection terminal is electrically connected to the processing unit 315 to transmit signals with the printing device. One side of the consumable chip 31 is a first contact surface 313, and the second connection terminal 312 is disposed on the first contact surface 313. The second connection terminal 312 does not include a ground terminal. The first connection terminal 311 is disposed in an area other than the first contact surface 313, that is, one end of the connector is fixedly disposed in an area other than the first contact surface 313 of the consumable chip 31. The consumable chip 31 includes a second contact surface 314, and the first contact surface 313 and the second contact surface 314 are located on opposite sides of the consumable chip 31. The first connection terminal 311 is located on the second contact surface 314. The second contact surface 314 faces the consumable box 3; when the outer shell of the consumable box 3 is made of conductive material, the first connection terminal 311 is electrically connected to the outer shell of the consumable box 3 through contact, and the first connection terminal 311 is electrically connected to the second connector 142 through the outer shell of the consumable box 3.

[0061] Preferably, the processing unit 315 is disposed on the second contact surface 314. For example... Figure 5 As shown, the second connection terminal 312 includes a data terminal 312a, a clock terminal 312b, a power terminal 312c, and a chip select terminal 312d. When the consumable box 3 is installed on the cartridge 2, the first connection terminal 311 of the consumable chip 31 forms an electrical connection with the second connector 142, the second connector 142 contacts the third conductive part 121, and the first connection terminal 311 is connected to the circuit ground point, thereby forming an electrical connection between the third conductive part 121 and the circuit ground point in the consumable chip 31. Figure 7 As shown, the consumable chip 31 includes a processing unit 315, which includes a storage module 3151 and a signal processing module 3152. The storage module 3151 is used to store relevant information, the processing unit 315 includes a circuit ground point, and the signal processing module 3152 is capable of processing the ground signal obtained from the conductive part 12.

[0062] Example 4

[0063] The difference between this embodiment and embodiment 3 is that the first connecting terminal 311 and the second connecting terminal 312 can be on the same contact surface, that is, one end of the connector is fixedly disposed on the first contact surface 313 of the consumable chip 31; in one possible implementation, the first connecting terminal 311 does not contact one of the connecting pins 131 used to provide a ground signal, and the first connecting terminal 311 is electrically connected to the second connector 142 to form a grounding loop.

[0064] In embodiments 1-4 of this application, the processing unit 315 is located on the second contact surface 314, which is opposite to the first contact surface 313 (i.e., the side of the consumable chip 31 that contacts the printing device). By reducing the number of grounding terminals on the side of the consumable chip 31 that contacts the printing device, the number of vias that the terminals need to connect to the processing unit 315 is reduced. In addition, it can also prevent the consumable chip 31 from shifting when the consumable box 3 is installed on the printing device, which would cause unstable contact between the grounding terminals and the printing device.

[0065] The consumable chip 311 can be used to store relevant information. The first connection terminal 311 can be used as a terminal connected to the circuit ground point in the consumable chip to improve the safety of the device with the consumable chip 31 during use. The second connection terminal 312 can be used to transmit the information stored in the consumable chip 31 after being electrically connected to the conductive element 13. Positioning the first connection terminal 311 (for grounding) and the second connection terminal 312 (for transmitting information) on different surfaces of the consumable chip 31 makes it easier to distinguish the types of connection terminals during use.

[0066] In a possible implementation, the first connection terminal 311 is located on the surface of the consumable chip 31, and correspondingly, one end of the connecting member is fixed on the surface of the consumable chip 31.

[0067] Specifically, the first connection terminal 311 can be located on the surface opposite to the first contact surface 313, or can be located on the side surface of the consumable chip 31. The first connection terminal 311 is located on the surface of the region of the consumable chip 31 other than the first contact surface 313, which can facilitate the electrical connection between the first connection terminal 311 and the second connecting member 141, and is conducive to reducing the processing difficulty and more in line with the actual use requirements.

[0068] The first connection terminal 311 is located on the surface with a larger area of the consumable chip 31, thereby facilitating the increase of the area of the first connection terminal 311, facilitating the electrical connection between the first connection terminal 311 and the connecting member 14, thereby improving the stability of the electrical connection between the first connection terminal 311 and the connecting member, and more in line with the actual use requirements.

[0069] In a possible implementation, the first connection terminal 311 is located inside the consumable chip 31. By embedding the first connection terminal 311 inside the consumable chip 31, the space occupied by the first connection terminal 311 on the surface of the consumable chip 31 can be reduced, the structure of the consumable chip 31 can be optimized, and the consumable chip 31 can have more area for electrical connection. The connecting member can be pre-buried in the inside of the consumable chip 31 when the consumable chip 31 is processed, and electrically connected with the first connection terminal 311, that is, one end of the connecting member is embedded in the inside of the consumable chip 31.

[0070] Each second connection terminal 312 is electrically connected with the connecting contact pin 131 on the conductive member 13, so as to realize the communication process between the consumable cartridge 3 and the printing device.

[0071] Based on the consumable chip 31 involved in the above embodiments, the application further provides a consumable cartridge 3 comprising the consumable chip 31 involved in any of the above embodiments.

[0072] The application further provides a printing device, which can comprise the consumable cartridge 3 and the consumable chip 31 involved in any of the above embodiments. Since the consumable chip 31 has the above technical effects, the printing device comprising the consumable cartridge 3 and the consumable chip 31 also has corresponding technical effects, which will not be described here.

[0073] The consumable chip 31 can be used to store information of the consumable cartridge 3. When the conductive member 13 is electrically connected to the second connecting terminal 312 after the consumable cartridge 3 is installed in the printing device, the printing device can read the information stored in the consumable chip 31 to obtain the relevant information of the consumable cartridge 3. When the position of the consumable chip 31 is offset, the first connecting terminal 311 can still form a normal electrical connection. The connection between the two is facilitated and the stability of the connection is improved.

[0074] In a possible implementation, the printing device includes at least two consumable cartridges 3, and the consumable chip 31 of each consumable cartridge 3 is provided with a first connecting terminal 311. Each first connecting terminal 311 forms a grounding loop through the corresponding connecting member 14.

[0075] In a possible implementation, the printing device includes at least two consumable cartridges 3, and the first connecting terminal 311 is shared by each consumable cartridge 3.

[0076] In a possible implementation, the first connecting terminal 311 can be a conductive member.

[0077] The processing unit 315 can include a storage module and a signal processing module, which can be designed integrally in an integrated circuit or a die. When the storage module is designed as a die, the storage module can be fixed to the flexible circuit board in a soft package or a hard package. The storage module can be a non-volatile memory, such as an erasable programmable read-only memory (EPROM), an electrically erasable programmable read only memory (EEPROM), a flash memory, a ferroelectric processing unit, a phase change memory module, etc. The signal processing module can be a microcontroller unit (MCU), a microcontroller, a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc. The signal processing module is used to process the communication between the consumable chip 31 and the printing device, read information from the processing unit, and store information to the processing unit. The consumable chip 31 further includes a circuit board, and the terminals and the processing unit are arranged on the surface of the circuit board. When the consumable cartridge 3 with the consumable chip 31 is installed in the printing device, the terminals on the circuit board are electrically connected to the printing device, so that the printing device can read the data of the processing unit through the terminals.
