Description

Technical Field

[0001] The present application relates to the field of electronic imaging technology, and in particular to a consumable chip, consumables, an image forming device, a detection method and a storage medium. Background Art

[0002] At present, a processing box for imaging is detachably installed in an image forming device such as a printer. Since the image forming performance of the image forming device will be affected when the processing box is disassembled or moved, it is necessary to detect whether the processing box is disassembled or moved, so as to timely calibrate and adjust relevant parameters to ensure the image forming performance of the image forming device. For example, replacing the processing box or disassembling the processing box and then installing it back usually causes the state of the processing box in the image forming device to change, and the original control parameters of the imaging system, such as laser exposure power, high voltage parameters, etc., are no longer the optimal configuration, thereby affecting the imaging effect. At present, the usual detection scheme is to use a travel switch and a photoelectric switch to determine whether the processing box is disassembled or moved, but adopting this scheme will increase additional structural design and electrical connection wires, resulting in increased costs. Summary of the invention

[0003] In view of this, the present application provides a consumable chip, consumables, image forming device, detection method, electronic device and storage medium to solve the problem that in the prior art, travel switches and photoelectric switches are used to determine whether the processing box has been disassembled or moved, which adds additional structural design and electrical connection wires, resulting in increased costs.

[0004] In a first aspect, an embodiment of the present application provides a consumable chip, wherein the consumable chip is used to be installed on a consumable, and the consumable is used to be installed at a designated position of an image forming device, and the consumable chip includes:

[0006] A first contact point is provided on the consumable chip body and is used to electrically connect with a contact point of the image forming device when the consumable is installed at the designated position, so as to exchange information with the image forming device;

[0007] A second contact point is disposed on the consumable chip body and is used to send a specific detection signal to the image forming device when electrically connected to a contact point of the image forming device, wherein the specific detection signal is used to indicate that the consumable has been displaced;

[0008] Wherein, when the consumable leaves the designated position of the image forming device, the contact point of the image forming device moves along a preset displacement track on the consumable chip body, and the second contact points are distributed on the preset displacement track.

[0009] The embodiment of the present application sets the second contact on a preset displacement trajectory, so that when the consumable leaves the specified position of the image forming device, the contact of the image forming device moves along the preset displacement trajectory to be electrically connected to the second contact to receive a specific detection signal output by the second contact. No additional structural design and electrical connection lines are required, thereby reducing chip costs.

[0010] Moreover, the embodiment of the present application detects whether the consumable material has been displaced through a specific detection signal, which is more identifiable than a simple high-level or low-level signal, avoids detection errors, and enhances the reliability of the detection results.

[0012] The preset displacement track of the embodiment of the present application can cover a relatively large range, and arranging the first contact point and the second contact point at both ends of the displacement track can ensure the accuracy of the contact connection with the image forming device.

[0013] In a possible implementation, the image forming device includes a plurality of contact points, and each of the contact points moves along a different preset displacement track on the consumable chip body.

[0014] In the embodiment of the present application, the contact point of the image forming device can be realized by a contact spring, that is, the image forming device includes a plurality of contact springs, and each contact spring moves along a different preset displacement trajectory on the consumable chip body.

[0018] In the embodiment of the present application, the second power contact, the second ground contact and the signal output contact are respectively distributed on different preset displacement tracks, and can be respectively electrically connected to the contacts of the corresponding image forming device to form corresponding information transmission channels.

[0019] In a possible implementation manner, the second ground contact and the first ground contact are distributed on the same preset displacement track.

[0020] In an embodiment of the present application, the second grounding contact and the first grounding contact are arranged on the same preset displacement track, so that the grounding contact of the image forming device can be electrically connected to the second grounding contact and the first grounding contact respectively when moving along the preset displacement track, without setting an additional grounding contact on the image forming device, thereby reducing the complexity of the circuit structure design.

[0021] In a possible implementation, the contact point of the image forming device moves along a preset displacement track on the consumable chip body, including:

[0022] When the contact of the image forming device moves along a preset displacement trajectory on the consumable chip body, it first completes the electrical connection with the second grounding contact, then completes the electrical connection with the second power contact, and finally completes the electrical connection with the signal output contact.

[0023] The embodiment of the present application can reduce the impact caused by the instability of the power supply and the ground line when the second contact is electrically connected to the contact of the image forming device, thereby ensuring the stability of the detection signal.

[0024] In a possible implementation, the contact point of the image forming device moves along a preset displacement track on the consumable chip body, including:

[0067] 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.

[0068] It should be clear that the described embodiments are only part 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 ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0069] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" 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 other meanings.

[0070] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0071] It should be understood that in the following description, "circuit" refers to a conductive loop composed of at least one element or subcircuit through electrical connection or electromagnetic connection. When an element or circuit is said to be "connected to" another element or an element / circuit is said to be "connected between" two nodes, it can be directly coupled or connected to another element or there can be an intermediate element, and the connection between the elements can be physical, logical, or a combination thereof. Conversely, when an element is said to be "directly coupled to" or "directly connected to" another element, it means that there is no intermediate element between the two.

[0072] At present, a processing box for imaging is detachably installed in an image forming device such as a printer. Since the image forming performance of the image forming device will be affected when the processing box is disassembled or moved, it is necessary to detect whether the processing box has been disassembled or moved, so as to make timely corrections and adjustments to relevant parameters to ensure the image forming performance of the image forming device. For example, replacing the processing box or disassembling the processing box and then installing it back usually causes the state of the processing box in the image forming device to change, and the original control parameters of the imaging system, such as laser exposure power, high voltage parameters, etc., are no longer the optimal configuration, thereby affecting the imaging effect. At this time, it is necessary to perform a color correction on the image forming device to put the control parameters of the imaging system of the image forming device in the best state to ensure the imaging quality of the printer. At present, the usual detection scheme is to use a travel switch and a photoelectric switch to determine whether the processing box has been disassembled or moved, but adopting this scheme will add additional structural design and electrical connection wires, resulting in increased costs.

[0073] In view of the above problems, the embodiments of the present application provide consumable chips, consumables, image forming devices, detection methods, electronic devices, and storage media. The embodiments of the present application set the second contact on a preset displacement track, so that when the consumable leaves the specified position of the image forming device, the contact of the image forming device moves along the preset displacement track to be electrically connected to the second contact to receive a specific detection signal output by the second contact, without the need for additional structural design and electrical connection wires, thereby reducing chip costs.

[0074] The following is a description with reference to the accompanying drawings.

[0075] See also Figure 1 , is a schematic diagram of the structure of a consumable chip provided in an embodiment of the present application. Figure 1 As shown, the consumable chip 100 includes a consumable chip body 110, a first contact 120 disposed at one end of the consumable chip body, and a second contact 130 disposed at the other end of the consumable chip body, wherein the consumable chip 100 is used to be installed on a consumable, and the consumable is used to be detachably installed at a designated position of an image forming device. Exemplarily, the consumable may be an ink cartridge or a toner cartridge, etc. The image forming device includes but is not limited to a printer, a copier, a fax machine, a multifunctional image making and copying device, an electrostatic printing device, and any other similar device.

[0076] In a specific implementation, the consumables can be installed at a designated position of the image forming device along a preset displacement track, and when the consumables are installed at the designated position of the image forming device, the first contact 120 is electrically connected to the contact of the image forming device, so that a first information transmission channel is formed between the consumable chip 100 and the image forming device, and the consumable chip 100 interacts with the image forming device through the first information transmission channel. When the consumables are not installed at the designated position of the image forming device, such as when the consumables leave the designated position of the image forming device along the preset displacement track, the second contact 130 is electrically connected to the contact of the image forming device, so that a second information transmission channel is formed between the consumable chip 100 and the image forming device, and the consumable chip 100 sends a specific detection signal to the image forming device through the second information transmission channel, and the specific detection signal is used to characterize the displacement of the consumables, so that it can be determined that the consumables are disassembled or moved. It can be understood that the specific detection signal can reflect that the consumables have left the designated position of the image forming device, or the consumables are not installed at the designated position of the image forming device, for example, the consumable installation state may change after the consumables are replaced or disassembled and then installed back.

[0077] In a specific implementation, when the consumable leaves the designated position of the image forming device, the contact of the image forming device leaves the first contact 120 on the consumable chip body 110 and moves along a preset displacement track, and the second contact 130 is distributed on the preset displacement track. The second contact 130 is arranged on the preset displacement track, so that the contact of the image forming device can be electrically connected to the second contact 130 during the movement along the preset displacement track, thereby establishing a second information transmission channel, and the image forming device receives a specific detection signal output by the second contact 130 through the second information transmission channel. This arrangement eliminates the need for additional structural design on the consumable chip 100, thereby reducing chip costs.

[0078] It is understandable that the preset displacement trajectory of the contacts of the image forming device on the consumable chip body can be the same as the preset displacement trajectory of the designated position where the consumable is installed or leaves the image forming device. In some embodiments, when the consumable leaves the designated position of the image forming device, the contacts of the image forming device leave the contact area of ​​the first contact and move along the preset displacement trajectory to the contact area of ​​the second contact, and the first contact and the second contact are distributed at both ends of the preset displacement trajectory. The coverage range of the preset displacement trajectory of the embodiment of the present application is relatively large. The first contact and the second contact are set at both ends of the chip body, that is, the first contact and the second contact are set at both ends of the preset displacement trajectory, so that the first contact and the second contact have sufficient contactable areas, ensuring the accuracy of the first contact and the second contact when connected to the contacts of the image forming device and sufficient connection time.

[0079] In a possible implementation, the image forming device includes a plurality of contact points, and when the consumable leaves the designated position of the image forming device, each contact point moves on the consumable chip body 110 along a different preset displacement track, that is, the consumable chip body 110 includes a plurality of preset displacement tracks. In a specific implementation, the plurality of contact points of the image forming device can be arranged in parallel along the vertical direction, and in this case, the shapes of the preset displacement tracks of each contact point on the consumable chip body 110 are similar.

[0080] In one possible implementation, Figure 2 As shown, the first contact 120 includes a first power contact (Volt Current Condenser, VCC) 121, a data signal contact (Serial Data, SDA) 122, a first ground contact (Ground, GND) 123 and a clock signal contact (Clock, CLK) 124, and the second contact 130 includes a signal output contact 131, a second ground contact 132 and a second power contact 133.

[0081] In a specific implementation, since the starting point of the contact of the image forming device moving along the preset displacement track on the consumable chip body 110 is the first contact 120 during the process of the consumable leaving the designated position of the image forming device, the first contact 120 is also distributed on the preset displacement track, and the first power contact 121, data signal contact 122, first ground contact 123 and clock signal contact 124 of the first contact 120 are respectively distributed on different preset displacement tracks. When the consumable is installed at the designated position of the image forming device, each contact of the first contact 120 is electrically connected to the corresponding contact of the image forming device to form a first information transmission channel.

[0082] Similarly, the signal output contact 131, the second ground contact 132 and the second power contact 133 are also distributed on different preset displacement tracks, so as to be electrically connected to the contacts of the corresponding image forming device when the consumable leaves the designated position of the image forming device, thereby forming a second information transmission channel.

[0083] In one possible implementation, the second grounding contact 132 and the first grounding contact 123 can be distributed on the same preset displacement trajectory, so that when the grounding contact of the image forming device moves along the preset displacement trajectory, it can be electrically connected to the second grounding contact and the first grounding contact respectively, without setting an additional grounding contact on the image forming device, thereby reducing the complexity of the circuit structure design.

[0084] In one possible implementation, according to the contacts included in the first contact 120, the image forming device may be correspondingly provided with a first connection contact, a second connection contact, a third connection contact and a fourth connection contact, wherein, when the consumable is installed to a specified position of the image forming device, the first connection contact may be electrically connected to the first power contact 121, the second connection contact may be electrically connected to the data signal contact 122, the third connection contact may be electrically connected to the first ground contact 123, and the fourth connection contact may be electrically connected to the clock signal contact 124, and when the consumable is displaced and the contact of the image forming device is electrically connected to the second contact 130, in addition to the third connection contact being electrically connected to the second ground contact 132, the signal output contact 131 and the second power contact 133 in the second contact 130 may be electrically connected to the contacts of any different image forming devices, respectively. Exemplarily, the signal output contact 131 can be electrically connected to the first connection contact, and the second power contact 133 can be electrically connected to the second connection contact, and this situation also indicates that the signal output contact 131 and the first power contact 121 are distributed on the same preset displacement track, and the second power contact 133 and the data signal contact 122 are distributed on the same preset displacement track; or the signal output contact 131 can be electrically connected to the first connection contact, and the second power contact 133 can be electrically connected to the fourth connection contact, and this situation also indicates that the signal output contact The signal output contact 131 and the first power contact 121 are distributed on the same preset displacement track, and the second power contact 133 and the clock signal contact 124 are distributed on the same preset displacement track; or the signal output contact 131 can be electrically connected to the second connection contact, and the second power contact 133 can be electrically connected to the fourth connection contact, and this situation also indicates that the signal output contact 131 and the data signal contact 122 are distributed on the same preset displacement track, and the second power contact 133 and the clock signal contact 124 are distributed on the same preset displacement track. or the signal output contact 131 can be electrically connected to the second connection contact, the second power contact 133 can be electrically connected to the first connection contact, and this situation also shows that the signal output contact 131 and the data signal contact 122 are distributed on the same preset displacement track, and the second power contact 133 and the first power contact 121 are distributed on the same preset displacement track; or the signal output contact 131 can be electrically connected to the fourth connection contact, the second power contact 133 can be electrically connected to the first connection contact, and this situation also shows that the signal output contact 1 31 and the clock signal contact 124 are distributed on the same preset displacement track, and the second power contact 133 and the first power contact 121 are distributed on the same preset displacement track; or the signal output contact 131 can be electrically connected to the fourth connection contact, and the second power contact 133 can be electrically connected to the second connection contact, and this situation also indicates that the signal output contact 131 and the clock signal contact 124 are distributed on the same preset displacement track, and the second power contact 133 and the data signal contact 122 are distributed on the same preset displacement track.

[0085] In a possible implementation, if the consumables are installed to the designated position of the image forming device along the preset displacement track, during the installation and movement process, the contact of the image forming device may be electrically connected to the second contact 130 first, and then to the first contact 120. Exemplarily, during the installation of the consumables to the designated position of the image forming device along the preset displacement track, that is, during the movement of the consumables, the second connection contact may be electrically connected to the signal output contact 131 first, and then to the data signal contact 122, the third connection contact may be electrically connected to the second ground contact 132 first, and then to the first ground contact 123, the fourth connection contact may be electrically connected to the second power contact 133 first, and then to the clock signal contact 124, and since the second contact does not have a corresponding contact on the preset displacement track corresponding to the first connection contact, the first connection contact is only electrically connected to the first power contact 121.

[0086] Corresponding to the above embodiment, in the process of the consumable leaving the designated position of the image forming device along the preset displacement track, the contact of the image forming device changes from being electrically connected to the first contact 120 to being electrically connected to the second contact 130. Exemplarily, in the process of the consumable leaving the designated position of the image forming device along the preset displacement track, the second connection contact changes from being electrically connected to the data signal contact 122 to being electrically connected to the signal output contact 131, the third connection contact changes from being electrically connected to the first ground contact 123 to being electrically connected to the second ground contact 132, and the fourth connection contact changes from being electrically connected to the clock signal contact 124 to being electrically connected to the second power contact 133. Since the second contact does not have a corresponding contact on the preset displacement track of the first connection contact, the first connection contact simply leaves the first power contact 121 and moves along the preset displacement track.

[0087] In a possible implementation, the preset displacement track of the contact point of the image forming device on the consumable chip body 110 is as follows: Figure 3 As shown, the preset displacement track of the first connection contact on the consumable chip body 110 is the first preset displacement track 141, the preset displacement track of the second connection contact on the consumable chip body 110 is the second preset displacement track 142, the preset displacement track of the third connection contact on the consumable chip body 110 is the third preset displacement track 143, and the preset displacement track of the fourth connection contact on the consumable chip body 110 is the fourth preset displacement track 144. The first contact 120 and the second contact 130 can be correspondingly arranged at the two ends of these tracks.

[0088] It should be noted that Figure 3 The preset displacement track is only an exemplary description and should not be used as a limitation on the protection scope of the present application. In specific implementations, users can design the shape of the preset displacement track according to their needs.

[0089] In practical applications, in order to reduce the impact caused by the instability of the power supply and grounding wire when the second information transmission channel is activated and ensure the stability of the detection signal, it is necessary to ensure that the contacts of the image forming device are connected to the signal output contact 131 last when they are electrically connected to the second contact 130, that is, they are grounded and power is provided first, and then the specific detection signal is output. Since the embodiment of the present application is mainly to detect whether the consumables are displaced, that is, whether the consumables are disassembled or moved after being installed at the designated position of the image forming device, it is necessary to ensure that when the consumables leave the designated position of the image forming device along the preset displacement trajectory, the contacts of the image forming device are connected to the signal output contact 131 last when they are electrically connected to the second contact 130.

[0090] In one possible implementation, when the consumable 100 leaves the designated position along a preset displacement trajectory, the contact of the image forming device leaves the contact area of ​​the first contact and moves along the preset displacement trajectory on the consumable chip body 110, and then completes the electrical connection with the first ground contact 132, then completes the electrical connection with the first power contact 133, and finally completes the electrical connection with the signal output contact 131.

[0091] In another possible implementation, when the consumable 100 leaves the designated position along a preset displacement trajectory, the contact of the image forming device leaves the contact area of ​​the first contact and moves along the preset displacement trajectory on the consumable chip body 110. It can also simultaneously complete the electrical connection with the first ground contact 132 and the first power contact 133, and then complete the electrical connection with the signal output contact 131.

[0092] That is, when the contact of the image forming device is electrically connected to the signal output contact 131 , the first ground contact 132 and the first power contact 133 are also electrically connected to the contact of the image forming device.

[0093] In a specific implementation, when the consumable leaves the specified position of the image forming device along a preset displacement trajectory, that is, when the consumable is displaced, the contacts of the image forming device also move from the first contact to the second contact on the consumable chip along the preset displacement trajectory. Therefore, the electrical connection sequence between the contacts of the image forming device and each contact in the second contact can be adjusted by changing the setting position or contact area of ​​the second contact 130 on the consumable chip body 110.

[0094] See also Figure 4 , is a schematic diagram of the position layout of a second contact point on a consumable chip body provided in an embodiment of the present application. Figure 4As shown in (a), the minimum distance X1 between the first grounding contact 132 and the first contact is less than the minimum distance X2 between the first power contact 133 and the first contact and less than the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming device moves from the first contact 120 to the second contact 130, it will first complete the electrical connection with the first grounding contact 132, then complete the electrical connection with the first power contact 133, and finally complete the electrical connection with the signal output contact 131. Or as Figure 4 As shown in (b), the minimum distance X1 between the first grounding contact 132 and the first contact = the minimum distance X2 between the first power contact 133 and the first contact < the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming device moves from the first contact to the second contact, it will first complete the electrical connection with the first grounding contact 132 and the first power contact 133 at the same time, and then complete the electrical connection with the signal output contact 131.

[0095] See also Figure 5 , is a schematic diagram of the contact area layout of a second contact on the consumable chip body provided in an embodiment of the present application. Figure 5 As shown in (a), the contact area of ​​the first grounding contact 132 is greater than the contact area of ​​the first power contact 133 and greater than the contact area of ​​the signal output contact 131, which means that the minimum distance X1 between the first grounding contact 132 and the first contact is less than the minimum distance X2 between the first power contact 133 and the first contact and less than the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming device moves from the first contact to the second contact, it will first complete the electrical connection with the first grounding contact 132, then complete the electrical connection with the first power contact 133, and finally complete the electrical connection with the signal output contact 131. Or as Figure 5 As shown in (b), the contact area of ​​the first grounding contact 132 = the contact area of ​​the first power contact 133 > the contact area of ​​the signal output contact 131. Correspondingly, the minimum distance X1 between the first grounding contact 132 and the first contact = the minimum distance X2 between the first power contact 133 and the first contact < the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming device moves from the first contact to the second contact, it will first complete the electrical connection with the first grounding contact 132 and the first power contact 133 at the same time, and then complete the electrical connection with the signal output contact 131.

[0096] Of course, in a specific implementation, the contact area can also be arranged in other ways, such as aligning the center lines of each contact area. The embodiment of the present application does not make specific requirements for this, as long as it is ensured that when the contact of the image forming device moves from the first contact to the second contact, it is finally connected to the signal output contact 131.

[0097] In a possible implementation, when the image forming device includes multiple contacts, the electrical connection sequence between each contact of the image forming device and each contact in the second contact can be adjusted by changing the setting position or contact area of ​​each contact of the image forming device. Figure 4 and Figure 5 For the sake of brevity, the description of the illustrated embodiment will not be repeated herein.

[0098] It should be noted that when adjusting the electrical connection sequence between each contact of the image forming device and each contact in the second contact by changing the setting position or contact area of ​​each contact of the image forming device, it is necessary to adjust the setting position or contact area of ​​each contact in the first contact accordingly to ensure that when the consumables are installed at the specified position of the image forming device, each contact of the image forming device and each contact in the first contact are in an electrically connected state.

[0099] In one possible implementation, Figure 6 As shown, the area of ​​the signal output contact 131 on the preset displacement trajectory determines the output time length of the specific detection signal. If the area of ​​the signal output contact 131 is set too small, the output time of the specific signal will be short, and an effective specific detection signal cannot be obtained. Therefore, the area of ​​the signal output contact 131 on the preset displacement trajectory needs to be larger than the set area threshold so that when the consumable 100 leaves the specified position of the image forming device, the electrical connection time between the contact of the image forming device and the signal output contact 131 is greater than the set time threshold, thereby avoiding the situation where the output time of the specific detection signal is short and the signal cannot be detected due to the user moving the consumable too fast.

[0100] In a specific implementation, the area threshold may be set according to a multiple of a cycle required for outputting a specific detection signal, and the embodiment of the present application does not make specific requirements for this.

[0101] Of course, in practical applications, the output time length of a specific detection signal can also be increased by increasing the area of ​​the contact of the image forming device electrically connected to the signal output contact 131 in the direction of the preset displacement track, that is, the area of ​​the contact of the image forming device electrically connected to the signal output contact 131 in the direction of the preset displacement track needs to be greater than the set area threshold, or the output time length of a specific detection signal can also be ensured by simultaneously increasing the area of ​​the signal output contact 131 on the preset displacement track and the area of ​​the contact of the image forming device electrically connected to the signal output contact 131 in the direction of the preset displacement track. The embodiment of the present application does not make specific requirements for this.

[0102] In some embodiments, by setting the area of ​​the signal output contact 131 on the preset displacement trajectory to be larger than a set area threshold and setting the area of ​​the contact corresponding to the image forming device electrically connected to the signal output contact 131 to be larger than the set area threshold, the effective contact time between the signal output contact 131 and the contact corresponding to the image forming device can be made longer, thereby ensuring that the output time length of the specific detection signal is long enough.

[0103] In a possible implementation, the image forming device may form a first connection contact, a second connection contact, a third connection contact, and a fourth connection contact through the contact spring 200. Figure 7 As shown, one contact spring 200 represents one connection contact. When the consumable 100 moves along the preset displacement trajectory, the contact spring 200 moves along the corresponding preset displacement trajectory on the consumable chip body 110. Specifically, in the process of installing the consumable 100 to the designated position of the image forming device along the preset displacement trajectory, each contact spring 200 is first electrically connected to the second contact 130 along the corresponding preset displacement trajectory, and then electrically connected to the first contact 120. In the process of the consumable leaving the designated position of the image forming device along the preset displacement trajectory, each contact spring 200 moves from the first contact 120 to the second contact 130 along the corresponding preset displacement trajectory.

[0104] See also Figure 8 , which is a schematic diagram of the process of a consumable leaving a specified position of an image forming device along a preset displacement trajectory provided by the present application, wherein (a) is a schematic diagram of the electrical connection between the contact spring 200 and the first contact of the consumable chip 100 when the consumable is installed at the specified position of the image forming device, (b) is a schematic diagram of the contact spring 200 sliding on the consumable chip 100 along the preset displacement trajectory when the consumable is being disassembled, and (c) is a schematic diagram of the contact spring 200 and the consumable chip 100 after the consumable is disassembled.

[0105] The embodiment of the present application sets the first contact and the second contact on a preset displacement track of the contacts of the image forming device on the consumable chip body, so that as the consumable moves, the contacts of the image forming device are naturally electrically connected to the first contact and the second contact, thereby detecting the disassembly or movement of the consumable. The above-mentioned structural setting is used to detect the displacement of the consumable, which reduces additional structural design and circuit line design compared to the prior art.

[0106] In another possible implementation, the contact point of the image forming device may be set as a raised contact point, and the raised contact point moves along a preset displacement track on the consumable chip, wherein one raised contact point represents one connection contact point.

[0107] In practical applications, the first contact and the second contact can also be set as raised contacts, and electrical connection with the contacts of the image forming device can be achieved through the raised first contacts and the second contacts. At this time, the raised second contact can form a moving track on the image forming device, and correspondingly, the first contact is set at a position on the consumable chip corresponding to the position of the moving track.

[0108] In specific implementations, users may also set other styles of contacts, and the embodiments of the present application do not make specific requirements for this.

[0109] In a possible implementation, a detection circuit is further provided on the consumable chip for being electrically connected to the second contact 130 , and outputting a specific detection signal through the signal output contact 131 when the second contact 130 is electrically connected to a contact of the image forming device.

[0110] See also Fig. 9 , is a schematic diagram of a circuit structure of a detection circuit provided in an embodiment of the present application. Fig. 9 As shown, the detection circuit includes a Pierce oscillator 150 , wherein the Pierce oscillator 150 is provided with three circuit ports, which are electrically connected to the signal output contact 131 , the first ground contact 132 and the first power contact 133 respectively.

[0111] In practical applications, the Pierce oscillator 150 is an electronic oscillation circuit, which is particularly suitable for cooperating with a quartz oscillator crystal to generate an oscillation signal with specific characteristics. The Pierce oscillator 150 has a stable oscillation frequency, a simple circuit structure, and low cost. Therefore, using the Pierce oscillator 150 in the detection circuit can reduce the cost of the detection circuit.

[0112] In specific implementation, Fig.10 As shown, the Pierce oscillator 150 requires very few parts, including an inverter U, a resistor R, a quartz crystal X, and capacitors C1 and C2, wherein the quartz crystal X and the capacitors C1 and C2 form a bandpass filter in the form of a π-type network, which provides a 180° phase shift and a required voltage gain at about the resonant frequency of the quartz crystal. At the frequency at which oscillation occurs, the quartz crystal X exhibits inductance and can be regarded as an inductor with a high Q value. The 180° phase shift of the π-type network plus the negative gain of the inverter U together become a positive loop gain, which makes the bias voltage set by the resistor R unstable and leads to an oscillation output. The output frequency is equal to the oscillation frequency of the quartz crystal X. Therefore, the output frequency of the oscillator can be changed by changing the oscillation frequency of the quartz crystal X.

[0113] Of course, in practical applications, other signal generating circuits may also be used as detection circuits to output specific detection signals, and the embodiments of the present application do not make specific requirements for this.

[0114] In a specific implementation, when the contact point of the image forming device, such as the contact spring, is just electrically connected to the second contact point, Figure 3 As shown, the contacts of the image forming device move from the clock signal contact 124 to the first power contact 133, from the second ground contact 123 to the first ground contact 132, and from the data signal contact 122 to the signal output contact 131. At this time, the signal output contact 131 will output a detection signal with specific characteristics (such as a specific frequency, period, and voltage). At the same time, the image forming device detects the received signal in real time. If a detection signal with specific characteristics, that is, a specific detection signal, is detected, it is determined that the consumable has been displaced. If the detection signal with specific characteristics is not detected, it is determined that the consumable has not been displaced.

[0115] The embodiment of the present application detects whether the consumable material has been displaced through a specific detection signal, which is more identifiable than a simple high-level or low-level signal, avoids detection errors, and enhances the reliability of the detection results.

[0116] In specific implementation, Fig.11 As shown, a system on chip (SOC) is provided on the control panel of the image forming device, and the SDA port and the data input and output (IO) port of the SOC are electrically connected to the SDA port of the control panel for receiving the signal input by the SDA port of the control panel and controlling the SDA port of the control panel, the CLK port of the SOC is electrically connected to the CLK port of the control panel for outputting the clock signal through the CLK port of the control panel, the GND port of the control panel is electrically connected to the first ground contact 132, and can provide a ground signal for the consumable chip 100, the CLK port of the control panel is electrically connected to the first power contact 133, and can provide a power signal for the consumable chip 100, and the SDA port of the control panel is electrically connected to the signal output contact 131, and is used to receive a specific detection signal output by the signal output contact 131.

[0117] In actual applications, in order to avoid confusion with communication signals from other ports, the embodiment of the present application determines whether the consumable has been displaced by detecting a specific signal on the IO port of the SOC. Therefore, when the specific detection signal output by the signal output contact 131 is transmitted back to the SDA port, CLK port, or VCC port of the control panel, the IO port will be electrically connected to the SDA port, CLK port, or VCC port of the control panel to receive the specific detection signal at the IO port and detect the displacement of the consumable through the specific detection signal.

[0118] The embodiment of the present application arranges the detection circuit on the consumable chip, which can save additional structural design, and the detection circuit can be shared with the electrical connection wires of the consumable chip, so the electrical connection wires can also be saved.

[0119] Corresponding to the above embodiment, the present application embodiment provides a consumable material, including Figures 1 to 11 The consumable chip of the embodiment shown.

[0120] In a specific implementation, when the image forming device is a black and white printer, the consumables can be directly installed on the image forming device, and the consumable chips on the consumables are in contact with the contacts of the image forming device, such as the contact springs; when the image forming device is a color printer, multiple consumables can be provided. In one embodiment, the image forming device is provided with 4 consumables, and the consumables can be installed in a push-pull drawer of the image forming device, and the consumables can be installed on the image forming device through the push-pull drawer, such as Fig.12 The consumable chip 100 is mounted on the consumable 300, and the consumable 300 is mounted on the push-pull drawer 400. The consumable 300 is moved in the image forming device by the push-pull movement of the push-pull drawer 400, thereby achieving electrical connection between the first contact and the second contact of the consumable chip and the contact of the image forming device.

[0121] like Fig.13 As shown, after the four consumables 300 are installed on the push-pull drawer 400, they are installed to the designated position of the image forming device through the push-pull drawer 400. At this time, the first contact point is in contact with the contact spring 200 of the image forming device to achieve printing communication with the image forming device. When the push-pull drawer is moved to make the consumables leave the designated position, the contact spring 200 of the image forming device will leave the first contact point and move along the preset displacement track on the consumable chip body, thereby contacting and connecting with the second contact point. At this time, the consumable displacement detection communication is achieved between the consumable chip 100 and the image forming device.

[0122] Specifically, Fig.14 As shown, taking one of the four consumables as an example, during the process of the consumable 300 leaving the designated position and being disassembled, the positional relationship between the contact spring 200 and the consumable changes from Figure (a) to Figure (b). During this process, the contact spring 200 moves along a preset displacement trajectory on the consumable chip body and makes contact with the second contact point, thereby obtaining a specific detection signal, and determining whether the consumable has been displaced based on the specific detection signal.

[0123] In a specific implementation, when there are four consumables, a microcontroller unit (MCU) can be set in the image forming device, and the MCU is electrically connected to each consumable to receive a specific detection signal sent by each consumable, such as Fig.15 As shown. Among them, the MCU can only set one power port VCC and one ground port GND to be electrically connected with each consumable. Other port settings and circuit connection settings of the MCU can refer to Fig.11For the sake of simplicity, the circuit shown in the embodiment of the present application will not be described in detail here.

[0124] At the same time, other specific contents of the embodiments of the present application can be found in the description of the above-mentioned consumable chip embodiments. For the sake of brevity, they will not be repeated here.

[0125] It should be noted that Fig.15 In the figure, the dotted arrows on each consumable chip can represent the preset displacement trajectory of the contacts of the image forming device on the body of each consumable chip, or can represent the line through which the specific detection signal output by the detection circuit is transmitted back to the image forming device when the contacts of the image forming device are electrically connected to the contacts (signal output contacts, second ground contacts, and second power contacts) corresponding to the connection of the detection circuit. However, it should be noted that Fig.15 The dotted arrows in the figure are for illustrative purposes only and are not intended to limit the scope of protection of the embodiments of the present application.

[0126] Corresponding to the above-mentioned embodiment, an embodiment of the present application provides an image forming device, including the consumable chip or consumables of the above-mentioned embodiment.

[0127] Corresponding to the above embodiment, the present application embodiment provides a method for detecting displacement of consumables, which is applied to an image forming device. The consumables included in the image forming device are the consumables described in the above embodiment, and when the consumables leave the designated position of the image forming device, the image forming device is electrically connected to the second contact. Fig.16 As shown, the detection method includes:

[0128] S1601: receiving a specific detection signal from a second contact;

[0129] S1602: Determine whether the specific detection signal is consistent with the preset detection signal;

[0130] S1603: If the specific detection signal is consistent with the preset detection signal, it is determined that the consumable has been displaced.

[0131] In the embodiment of the present application, a preset detection signal can be set according to the oscillation signal of the Pierce oscillator. When the image forming device receives a specific detection signal, the specific detection signal is compared with the preset detection signal. If the specific detection signal is consistent with the preset detection signal, it is determined that the consumable has been displaced. In a specific embodiment, in order to prevent the signal on the SDA and CLK of the consumable itself from interfering with the detection, the frequency design of the detection circuit should be clearly distinguished from the normal working frequency of the SDA and CLK of the consumable. When the consumable does not produce displacement, the image forming device cannot detect the specific frequency signal. When the consumable produces displacement, the detection circuit is electrically connected to the contact of the image forming device through the second contact. At this time, the detection signal is transmitted back to the SOC of the image forming device through the SDA or CLK or VCC port. The SOC only needs to determine whether the frequency characteristic of the specific detection signal is the frequency designed by the detection circuit. If so, it is determined that the consumable has been displaced. The embodiment of the present application determines that displacement has occurred by detecting a signal with a frequency characteristic. Compared with the method of detecting high and low levels, it is more reliable and accurate, and can reduce the situation of unclear signals and false touches.

[0132] In a possible implementation, the image forming device determines whether a specific detection signal meets expectations. If the specific detection signal is consistent with a preset detection signal, when it is determined that the specific detection signal meets expectations, it is determined that the push-pull drawer or consumables are pushed in and / or pulled out compared to the image forming device frame, and the number of times the push-pull drawer or consumables are pushed in and / or pulled out compared to the image forming device frame is counted. In this way, it is possible to determine whether color registration correction needs to be performed based on the number of times the push-pull drawer or consumables are pushed in or pulled out, so that color registration correction can be performed in a timely manner, thereby improving the quality of printed images of the image forming device.

[0133] For other specific contents of the embodiments of the present application, please refer to the description of the consumable chip and consumable embodiments mentioned above. For the sake of brevity, they will not be repeated here.
