[0075] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0076] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0077] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0078] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0079] It should be noted that the electrical connection described in this article refers to a conductive relationship between two conductive structural components, where the two conductive structural components can directly physically contact and conduct electricity, or the two conductive structural components can indirectly physically contact and conduct electricity through other conductive structural components.

[0080] In the accompanying diagram, directions X, Y, and Z are all perpendicular to each other, with direction Z representing the height direction. Direction J can be parallel to the plane containing directions X and Z, and can intersect or be parallel to direction X.

[0081] In a first aspect, embodiments of this application provide a processing cartridge that can be detachably installed in the mounting structure of an image forming apparatus (also known as a printer). The processing cartridge can contain toner, and the image forming apparatus can transfer the toner in the processing cartridge to a printing medium to form imprints such as text, images, and symbols on the printing medium. The printing medium can include printable materials such as paper, photographic paper, envelopes, and labels.

[0082] Please refer to Figures 1-2 As shown, the processing box 1 is not installed in the mounting structure 5. The processing box 1 can move along direction J towards the mounting structure 5 to make the processing box 1 be in the position shown. Figure 3 The image shows the state where it has been installed into mounting structure 5. Of course, as... Figure 3 The processing box 1 shown can also be detached from the mounting structure 5 in the reverse direction of J.

[0083] Please refer to Figure 4 As shown, the mounting structure 5 may be recessed and equipped with a first slide rail 511. Please refer to... Figure 5 As shown, the mounting structure 5 may be recessed and provided with a second slide rail 521. The first slide rail 511 and the second slide rail 521 can be used to guide the processing box to be installed in the mounting structure 5 along the direction J. Of course, the first slide rail 511 and the second slide rail 521 can also be used to guide the processing box to detach from the mounting structure 5 in the opposite direction J.

[0084] In other embodiments (not shown in the figures), the mounting structure may also be provided with other guide structures for guiding the processing box to move relative to the mounting structure in a set direction, such as a raised guide rail.

[0085] The following content of this article will mainly use the example of "the installation structure can be recessed and equipped with a first slide and a second slide".

[0086] Please refer to Figure 4 As shown, the image forming apparatus may further include a first positioning member 2, please refer to... Figure 5As shown, the image forming apparatus may further include a second positioning member 3, and both the first positioning member 2 and the second positioning member 3 are mounted on the mounting structure 5. When the processing cartridge is mounted on the mounting structure 5, both the first positioning member 2 and the second positioning member 3 are used to position the processing cartridge to prevent the processing cartridge from detaching from the mounting structure 5.

[0087] Please refer to Figure 3 As shown, the image forming apparatus may further include a detection component 4, which is mounted on the mounting structure 5. A conductive detection loop can be formed between the detection component 4 and the processing box 1. After the detection component 4 receives an electrical signal indicating that the conductive detection loop is connected, it can output a confirmation signal indicating that "the processing box 1 is accurately mounted in the set position of the mounting structure 5". If no conductive detection loop is formed between the detection component 4 and the processing box 1, the detection component 4 will not receive an electrical signal indicating that the conductive detection loop is connected, and it can output a warning signal indicating that "the processing box 1 is not accurately mounted in the set position of the mounting structure 5".

[0088] The processing box in this application embodiment may include a box body, such as... Figure 6 The first positioning member 121 shown and as shown Figure 7 The second positioning member 131 is shown. The first positioning member 121 and the second positioning member 131 can be spaced apart along the length direction of the box body (the direction parallel to direction Y).

[0089] In this embodiment, at least a portion of the structure of the first positioning member 121 is conductive, at least a portion of the structure of the second positioning member 131 is conductive, and at least a portion of the structure of the first positioning member 121 is electrically connected to at least a portion of the structure of the second positioning member 131.

[0090] Please refer to Figure 8 As shown, when the processing box is installed in the mounting structure, the first positioned member 121 can be positioned by the first positioning member 2. Please refer to... Figure 9 As shown, when the processing box is installed on the mounting structure, the second positioning member 131 can be positioned by the second positioning member 3. Under this setting, the processing box is not easily detached from the mounting structure, and the processing box can be reliably installed in the set position of the mounting structure.

[0091] When the processing box is installed in the set position of the mounting structure, at least a portion of the structure of the first positioning member 121 and at least a portion of the structure of the second positioning member 131 can be electrically connected to the detection component 4. In other words, a conductive detection circuit can be formed between the conductive structure in the first positioning member 121, the conductive structure in the second positioning member 131, and the detection component 4. Accordingly, the detection component 4 can output a confirmation signal, and the control component of the image forming apparatus can control the image forming apparatus to perform the printing operation normally after receiving the confirmation signal.

[0092] When the processing box is not installed in the set position of the mounting structure, no conductive detection circuit is formed between the conductive structure in the first positioning member 121, the conductive structure in the second positioning member 131, and the detection component 4. The detection component 4 can output a reminder signal to remind the user that the current image forming apparatus cannot perform the printing operation, so that the user can check in time whether the processing box is reliably installed in the set position of the mounting structure. After receiving the reminder signal, the control component of the image forming apparatus will not control the image forming apparatus to perform the printing operation.

[0093] It should be noted that the setting position of the mounting structure refers to the position where the processing cartridge can reliably perform printing operations.

[0094] It should be noted that the detection component and the control component can be integrated into the same circuit module (also known as a circuit board or data board), or the detection component and the control component can be located in different circuit modules.

[0095] In some embodiments of this application, at least a portion of the structure of the first positioning member 2 may be conductive, and the conductive structure in the first positioned member 121 may be electrically connected to the detection component through the conductive structure in the first positioning member 2.

[0096] In other embodiments, the image forming apparatus may also include other conductive structural components, and the conductive structure in the first positioned member can be electrically connected to the detection component through other conductive structural components.

[0097] In other embodiments, the conductive structure in the first positioning member can be directly electrically connected to the detection component.

[0098] The following content mainly uses the example of "the conductive structure in the first positioning member 121 is electrically connected to the detection component through the conductive structure in the first positioning member 2" to describe the process.

[0099] In some embodiments of this application, at least a portion of the structure of the second positioning member 3 may be conductive, and the conductive structure in the second positioned member 131 may be electrically connected to the detection component through the conductive structure in the second positioning member 3.

[0100] In other embodiments, the image forming apparatus may also include other conductive structural components, and the conductive structure in the second positioned member can be electrically connected to the detection component through other conductive structural components.

[0101] In other embodiments, the conductive structure in the second positioning member can be directly electrically connected to the detection component.

[0102] The following content mainly uses the example of "the conductive structure in the second positioning member 131 is electrically connected to the detection component through the conductive structure in the second positioning member 3" to describe the process.

[0103] Alternatively, please refer to Figure 6 As shown, the first positioned member 121 includes a first positioned structure 1211 and a first electrical connection portion 1212. Please refer to... Figure 8 As shown, the first positioning structure 1211 is used to be positioned by the first positioning member 2, and the first electrical connection part 1212 is used to be electrically connected to the detection component (not shown in the figure).

[0104] It should be noted that, please refer to Figure 8 As shown, the first electrical connection part 1212 and the detection component (not shown in the figure) can be indirectly electrically connected through the first positioning member 2 mentioned above.

[0105] Please refer to Figure 8 As shown, the first positioned structure 1211 may not be conductive, that is, the material of the first positioned structure 1211 may be an insulating material, such as insulating plastic.

[0106] In addition, the first electrical connection portion 1212 can be used not only for electrical connection to the detection component, but also for electrical connection to a conductive structure in the second positioning member. In other embodiments (not shown in the figures), the first positioning member may also include other electrical connection portions, which can be indirectly electrically connected to a conductive structure in the second positioning member through these other electrical connection portions.

[0107] In other embodiments, please refer to Figure 10 As shown, the overall structure of the first positioned member 121 can be conductive.

[0108] The following content of this article will mainly describe the first positioned component as including a first positioned structure that is not conductive and a first electrical connection portion that is conductive.

[0109] Alternatively, please refer to Figure 7 As shown, the second positioning member 131 includes a second positioning structure 1311 and a second electrical connection portion 1312. Please refer to... Figure 9 As shown, the second positioning structure 1311 is used to be positioned by the second positioning member 3, and the second electrical connection part 1312 is used to be electrically connected to the detection component.

[0110] It should be noted that, please refer to Figure 9 As shown, the second electrical connection part 1312 and the detection component (not shown in the figure) can be indirectly electrically connected through the second positioning member 3 mentioned above.

[0111] The second positioned structure 1311 may not be conductive; that is, the material of the second positioned structure 1311 may be an insulating material, such as insulating plastic.

[0112] In addition, the second electrical connection portion 1312 can be used not only for electrical connection to the detection component, but also for electrical connection to a conductive structure in the first positioning member. In other embodiments (not shown in the figures), the second positioning member may also include other electrical connection portions, which can be indirectly electrically connected to a conductive structure in the first positioning member through other electrical connection portions.

[0113] In other embodiments, please refer to Figure 11 As shown, the overall structure of the second positioned member 131 can be conductive.

[0114] The following content of this article will mainly describe the second positioning member as an example, which includes a second positioning structure that is not conductive and a second electrical connection part that is conductive.

[0115] It should be noted that the conductive structure in the first positioned member (e.g., the first electrical connection portion) and the conductive structure in the second positioned member (e.g., the second electrical connection portion) can be indirectly electrically connected through a conductive structural member (e.g., a wire) acting as an intermediary. Of course, in other embodiments, the electrical connection between the conductive structure in the first positioned member and the conductive structure in the second positioned member can also be a direct electrical connection.

[0116] Alternatively, please refer to Figure 12 As shown, the first positioning structure 1211 is provided with a first mounting hole 1211a. Please refer to... Figure 13 As shown, the first electrical connection part 1212 is installed on Figure 12 The first mounting hole 1211a is shown. With this configuration, during the installation or removal of the processing box from the mounting structure, even if the first positioning member contacts the first electrical connection 1212 and the first positioning member moves relative to the first electrical connection 1212, the first electrical connection 1212 can be reliably limited by the first mounting hole 1211a. The first electrical connection 1212 is less likely to move arbitrarily relative to the first positioned structure 1211. That is, the installation reliability of the mounting structure for the first electrical connection 1212 is high. Correspondingly, this also allows the associated conductive detection circuit to reliably detect whether the processing box is installed correctly.

[0117] The first electrical connection part can be bonded, snapped, or interference-fitted with the first mounting hole.

[0118] In other embodiments (not shown in the figures), the first positioning structure may not have mounting holes, and the first electrical connection portion may be attached to the surface of the first positioning structure.

[0119] In other embodiments (not shown in the figures), the first positioned structure may include a first recessed structure, and the first electrical connection portion may be disposed in the first recessed structure.

[0120] Alternatively, please refer to Figure 14 As shown, the second positioning structure 1311 is provided with a second mounting hole 1311a. Please refer to... Figure 15 As shown, the second electrical connection part 1312 is installed on Figure 14 The second mounting hole 1311a is shown. With this configuration, during the installation or removal of the processing box from the mounting structure, even if the second positioning member contacts the second electrical connection 1312 and the second positioning member moves relative to the second electrical connection 1312, the second electrical connection 1312 can be reliably limited by the second mounting hole 1311a. The second electrical connection 1312 is less likely to move arbitrarily relative to the second positioned structure 1311. That is, the installation reliability of the mounting structure for the second electrical connection 1312 is high. Correspondingly, this also allows the associated conductive detection circuit to reliably detect whether the processing box is installed correctly.

[0121] The second electrical connection part can be bonded, snapped, or interference-fitted with the second mounting hole.

[0122] In other embodiments (not shown in the figures), the second positioning structure may not have mounting holes, and the second electrical connection portion may be attached to the surface of the second positioning structure.

[0123] In other embodiments (not shown in the figures), the second positioned structure may include a second recessed structure, and the second electrical connection portion may be disposed in the second recessed structure.

[0124] Alternatively, please refer to Figure 13 As shown, the first positioning structure 1211 includes a first upper structure 12111 and a first lower structure 12112 distributed in the height direction of the processing box (parallel to direction Z), and a first electrical connection portion 1212 is mounted on the first upper structure 12111. Accordingly, if the processing box is mounted on the mounting structure, at least a portion of the structure of the first positioning member also needs to be located above at least a portion of the structure of the first upper structure 12111. Under this arrangement, it is possible to detect whether the mounting structure of the image forming apparatus and the processing box to be mounted are compatible.

[0125] The first positioning member can apply a downward pressing force to the first positioned structure 1211 (the direction of the pressing force can be parallel to the height direction, or the direction of the pressing force can be nearly parallel to the height direction), so that the processing box is pressed against the mounting structure. The part of the first positioning member used to press the first positioned structure 1211 can also be used to electrically connect with the first electrical connection part 1212. Under this setting, when the processing box is installed in the set position of the mounting structure, the processing box is not easy to detach from the mounting structure and the first positioning member can reliably connect with the first electrical connection part 1212.

[0126] In other embodiments (not shown in the figures), the first positioning member may also have a portion for pressing the first positioned structure and a portion for electrically connecting with the first electrical connection portion, and these two portions are not the same portion.

[0127] In other embodiments (not shown in the figures), the first positioned structure may include a first upper structure, a first middle structure, and a first lower structure distributed along the height direction of the processing box. The first middle structure is located between the first upper structure and the first lower structure, and the first electrical connection portion is mounted on the first upper structure.

[0128] In other embodiments (not shown in the figures), the first electrical connection portion may be mounted on the first lower structure.

[0129] Alternatively, please refer to Figure 15 As shown, the second positioning structure 1311 includes a second upper structure 13111 and a second lower structure 13112 distributed in the height direction of the processing box (a direction parallel to direction Z), and the second electrical connection portion 1312 is mounted on the second upper structure 13111. Accordingly, if the processing box is mounted on the mounting structure, at least a portion of the structure of the second positioning member also needs to be located above at least a portion of the structure of the second upper structure 13111. Under this arrangement, it is possible to detect whether the mounting structure of the image forming apparatus and the processing box to be mounted are compatible.

[0130] The second positioning member can apply a downward pressing force to the second positioned structure 1311 (the direction of the pressing force can be parallel to the height direction, or the direction of the pressing force can be nearly parallel to the height direction), so that the processing box is pressed against the mounting structure. The part of the second positioning member used to press the second positioned structure 1311 can also be used to electrically connect with the second electrical connection part 1312. Under this setting, when the processing box is installed in the set position of the mounting structure, the processing box is not easy to detach from the mounting structure and the second positioning member can reliably connect with the second electrical connection part 1312.

[0131] In other embodiments (not shown in the figures), the second positioning member may also have a portion for pressing the second positioned structure and a portion for electrically connecting with the second electrical connection portion, and these two portions are not the same portion.

[0132] In other embodiments (not shown in the figures), the second positioned structure may include a second upper structure, a second middle structure, and a second lower structure distributed along the height direction of the processing box. The second middle structure is located between the second upper structure and the second lower structure, and the second electrical connection portion is mounted on the second upper structure.

[0133] In other embodiments (not shown in the figures), the second electrical connection may be mounted on the second lower structure.

[0164] In other embodiments (not shown in the figures), the conductive element may also be installed in a structure outside the main body of the processing box.

[0165] Alternatively, please refer to Figure 16 and Figure 20 As shown, the conductive element 14 passes through the toner container 111. With this arrangement, at least a portion of the structure of the conductive element 14 can be reliably protected by the toner container 111.

[0166] In other embodiments (not shown in the figures), the conductive element may not be installed in the toner container.

[0167] Please refer to Figure 12 As shown, the first positioned structure 1211 is provided with a first cavity 1211b, and the first mounting hole 1211a communicates with the first cavity 1211b.

[0169] Secondly, embodiments of this application provide an image forming apparatus, which may include the first positioning member, second positioning member, detection component, mounting structure, and processing box mentioned above. The first positioning member, second positioning member, and detection component are all mounted on the mounting structure, and the processing box is detachably mounted on the mounting structure. When the processing box is mounted on the mounting structure, a first positioned member of the processing box is positioned by the first positioning member, and a second positioned member of the processing box is positioned by the second positioning member, thereby preventing the processing box from detaching from the mounting structure. At least a portion of the structure of the first positioned member of the processing box (e.g., a first electrical connection portion) can be electrically connected to the detection component through the first positioning member, and at least a portion of the structure of the second positioned member of the processing box (e.g., a second electrical connection portion) can be electrically connected to the detection component through the second positioning member. As mentioned above, within the processing box, at least a portion of the structure of the first positioned member (e.g., the first electrical connection portion) and at least a portion of the structure of the second positioned member (e.g., the second electrical connection portion) are electrically connected. Therefore, when the processing box is installed in the mounting structure, the first positioned component, the first positioning component, the detection component, the second positioning component, and the second positioned component can be connected in series to form a conductive detection circuit. This conductive detection circuit is used to detect whether the processing box is installed in place. The specific principles and effects have been described above and will not be repeated here.

[0170] The first positioning element not only has a positioning function but also a conductivity detection function; similarly, the second positioning element not only has a positioning function but also a conductivity detection function. With this configuration, the structure of the image forming apparatus is further simplified.

[0171] Accordingly, the image forming apparatus also includes the other technical effects of the processing box mentioned above, which have been described above and will not be repeated here.

[0172] When the processing box is not installed in the set position of the mounting structure, the positions of the first positioning member 2 and the first positioned member 121 relative to each other are as follows: Figure 21 As shown, when the first positioned member 121 moves along direction J and contacts the first positioning member 2, at least a portion of the structure of the first positioning member 2 can be lifted by the first positioned member 121 along direction K1. When the processing box is installed in the set position of the mounting structure, the positions of the first positioning member 2 and the first positioned member 121 relative to each other are as follows: Figure 22 As shown, the first positioning member 2, which was originally lifted, has moved downward along the K2 direction. The first positioning member 2 presses down on the first positioned member 121 to position the first positioned member 121, thereby preventing the processing box from detaching from the mounting structure and ensuring a reliable electrical connection between the first positioning member 2 and the first electrical connection part 1212.

[0173] Additionally, please refer to Figures 21-22 As shown, the first positioning member 2 may include a first conductive pressing part 21, a first conductive rotating connecting part 22, and a first conductive end 23. The first conductive pressing part 21 is used to press the first positioned member 121 and to be electrically connected to the first electrical connecting part 1212. The first rotating connecting part 22 is sleeved on the first mounting shaft 512 of the mounting structure 5. The first conductive end 23 is limitedly connected to the first limiting part 513 of the mounting structure 5. When the first positioned member 121 moves relative to the first conductive pressing part 21 and the first positioned member 121 presses the first conductive pressing part 21, as... Figure 18 The first positioned member 121 shown can drive the first conductive pressing part 21 to move along the K1 direction. The first conductive pressing part 21 will drive the first conductive rotating connecting part 22 to rotate clockwise in the M direction around the first mounting shaft 512, while the first conductive end 23 remains stationary relative to the mounting structure 5. When the first positioned member 121 moves relative to the first conductive pressing part 21 and the first positioned member 121 does not press the first conductive pressing part 21, such as Figure 19 The first conductive pressing part 21 shown will move along the K2 direction on its own, the first conductive rotating connecting part 22 will rotate counterclockwise N around the first mounting shaft 512, while the first conductive end 23 will remain stationary relative to the mounting structure 5. As can be seen from the above, the structure of the first positioning member 2 can elastically deform. Specifically, the first positioning member 2 may include a metal torsion spring structure or a metal leaf spring structure, or other metal elastic structures, to meet the needs of elastic deformation.

[0174] The first conductive pressing part 21 may include a V-shaped structure, a Z-shaped structure, or a U-shaped structure.

[0175] In other embodiments (not shown in the figures), the first positioning member may include a slider structure and an elastic member. The slider structure may be slidably connected to the mounting structure, and the slider structure may also be connected to the mounting structure through the elastic member. The elastic force of the elastic member can press the slider structure against the first positioning member to prevent the processing box from detaching from the mounting structure. The slider structure may be conductive, and the detection component may be electrically connected to the first electrical connection part through the slider structure.

[0176] The structure of the second positioning component can be similar to or the same as that of the first positioning component. The assembly relationship of the second positioning component can be similar to or the same as that of the first positioning component. The function of the second positioning component can be similar to or the same as that of the first positioning component. That is, the structure, assembly relationship and function of the second positioning component can be understood by referring to the content about the first positioning component described above. It will not be repeated here.

[0177] It should be noted that at least one of the first positioning element and the second positioning element can be directly electrically connected to the detection component. Alternatively, at least one of the first positioning element and the second positioning element can be indirectly electrically connected to the detection component via a conductive wire or other conductive element.

[0178] Furthermore, please refer to Figures 4-5 As shown, the mounting structure 5 may include a first side structural plate 51 and a second side structural plate 52 spaced apart. A first slide rail 511 is recessed on the side of the first side structural plate 51 facing the second side structural plate 52, and a second slide rail 521 is recessed on the side of the second side structural plate 52 facing the first side structural plate 51. Both the first slide rail 511 and the second slide rail 521 are used to slide with the processing box. The detection component 4 may be installed on the side of the first side structural plate 51 facing away from the second side structural plate 52.

[0179] In other embodiments (not shown in the figures), the detection component may also be mounted on the second side structural plate.

[0180] It should be noted that the image forming apparatus can also be called a toner printer or a laser printer.

[0181] It should be noted that, in order to clearly show the technical points of the embodiments of this application, the image forming apparatus in the accompanying drawings does not show other structures such as housings that can be used to accommodate the mounting structure.

[0182] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
