This application claims priority to Chinese Patent Application No. 202310845902.4, filed on Jul. 10, 2023, the entire content of which is incorporated herein by reference.
The present disclosure relates to the technical field of image forming and, in particular, to a triggering assembly, an adapter, a cartridge, a cartridge assembly, and a detection method.
With the development of printing imaging technology, image forming apparatuses such as printers, copiers, fax machines, word processors, etc. have been widely used. For convenience, the image forming apparatuses are usually equipped with consumables that are convenient for users to replace. For example, a consumable cartridge for containing recording materials (such as ink, toner, etc.) is referred to as a cartridge (such as an ink cartridge, a toner cartridge, a toner cylinder, etc.). When the recording material in the cartridge is consumed, the user only needs to replace the cartridge, and the image forming apparatus can continue to be used.
A color image forming apparatus includes a plurality of cartridges for containing toners of basic colors and an imaging assembly of corresponding basic colors arranged in the color image forming apparatus. A cartridge supplies the toner in the cartridge to the corresponding color imaging assembly. The imaging assembly includes a photosensitive drum, a charging assembly, and a developing assembly. The charging assembly can make the surface of the photosensitive drum uniformly charged. Thus, the uniformly charged surface of photosensitive drum carries an electrostatic latent image, and the electrostatic latent image is developed by the developing assembly and toner. By superimposing toners of multiple basic colors, a variety of colors can be obtained, thereby forming a color image. Exemplarily, a color image forming apparatus includes cartridges for containing yellow (Y), magenta (M), cyan (C), and black (K) toners respectively. Corresponding to the cartridges, accommodation cavities for accommodating the cartridges of corresponding colors is provided on the image forming apparatus. It can be understood that the yellow, magenta, cyan, and black cartridges are installed in the yellow, magenta, cyan and black accommodation cavities, respectively, in order.
In order to reduce costs, cartridges corresponding to different colors are usually set to a same structure in a standardized processing manner. Therefore, when a user installs cartridges of multiple colors, the installation order may be confused. For example, a magenta cartridge is installed in a cyan accommodation cavity; and a cyan cartridge is installed in a magenta accommodation cavity. In this case, magenta toner will be supplied to the cyan imaging assembly. Cyan toner will be supplied to the magenta imaging assembly, resulting in development degradation or image quality degradation, thereby affecting user experience.
In addition, the cartridge may not be properly installed due to the over length of the imaging assembly. When the cartridge is not properly installed, the toner in the cartridge cannot be normally supplied to the imaging assembly, which will also lead to development degradation or image quality degradation, thereby affecting the user experience.

Please note that described embodiments are only a part of embodiments of the present disclosure, rather than all embodiments. Based on embodiments of the present disclosure, other embodiments obtained by those persons of ordinary skill in the art without creative work are within the scope of protection of the present disclosure.
The terms used in embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. Singular forms “a”, “said”, and “the” used in embodiments of the present disclosure and claims are also intended to include plural forms, unless the context clearly indicates other meanings.
The main body 110 of the image forming apparatus includes a frame 111 and an accommodation cavity 112. The accommodation cavity 112 is used to accommodate the cartridge 150. A matching unit 114 is provided on a frame 111. An assembly unit 151 matching the matching unit 114 is provided on the cartridge 150. The assembly unit 151 matches with the matching unit 114, so that the cartridge 150 can be installed to a predetermined position in the accommodation cavity 112. In addition, a conductive unit 113 and an electric signal responding unit 115 are also provided on the frame 111. The electric signal responding unit 115 in the present disclosure is electrically connected to the conductive unit 113 and a control apparatus of the main body 110 of the image forming apparatus respectively. An electric signal triggering assembly 152 matching the conductive unit 113 is provided on the cartridge 150. When the cartridge 150 is installed to the predetermined position in the accommodation cavity 112, the electric signal triggering assembly 152 is electrically connected to the conductive unit 113, and triggers the electric signal responding unit 115 to obtain a predetermined responding signal. The predetermined responding signal is used to determine whether the installation of the cartridge 150 meets an expectation, that is, to determine whether the cartridge 150 is installed in place.
In the present disclosure, when the cartridge 150 is installed to a predetermined position in the accommodation cavity 112, the cartridge 150 is installed in the main body 110 of the image forming apparatus and can normally perform image forming operations, such as normal printing and normal supply of toner.
In one implementation, the predetermined responding signal is a high-level signal (for example, a 3.3V voltage signal). Specifically, when the cartridge 150 is installed to a predetermined position in the accommodation cavity 112, the electric signal triggering assembly 152 is electrically connected to the conductive unit 113, and triggers the electric signal responding unit 115 to obtain the high-level signal. According to the high-level signal, it can be determined that whether the installation of the cartridge 150 meets expectations, that is, it is installed in place. On the contrary, if the electric signal responding unit 115 obtains a low-level signal, it means that the installation of the cartridge 150 does not meet the expectation, that is, it is not installed in place.
Similarly, the predetermined responding signal can also be a low-level signal (e.g., a 0V voltage signal). Specifically, when the cartridge 150 is installed to the predetermined position in the accommodation cavity 112, the electric signal triggering assembly 152 is electrically connected to the conductive unit 113, and triggers the electric signal responding unit 115 to obtain a low-level signal. According to the low-level signal, it can be determined that whether the installation of the cartridge 150 meets the expectation, that is, it is installed in place. On the contrary, if the electric signal responding unit 115 obtains the high-level signal, it means that the installation of the cartridge 150 does not meet the expectation, that is, it is not installed in place.
In embodiments of the present disclosure, since the electric signal triggering assembly 152 can determine whether the installation of the cartridge 150 meets the expectation through a predetermined responding signal. This can avoid a scenario of development degradation or image quality degradation caused by improper installation of the cartridge 150.
To better convey the idea, a technical solution is exemplarily described below in conjunction with a specific structure of the image forming apparatus 100.
As shown in
It should be noted that the main body 110 of the image forming apparatus and the cartridges 150Y˜K shown in
Exemplarily, the first conductive component 1131 is connected to a 0V voltage, the second conductive component 1132 is connected to a 3.3V voltage, and the electric signal responding unit 115 is electrically connected to the first conductive component 1131. It can be understood that when the cartridge 150 is not installed to the predetermined position in the accommodation cavity 112, the first conductive component 1131 and the second conductive component 1132 are electrically isolated. The electric signal responding unit 115 obtains a 0V voltage. When the cartridge 150 is installed to the predetermined position in the accommodation cavity 112, the electric signal triggering assembly 152 is electrically connected to the first conductive component 1131 and the second conductive component 1132 respectively, thereby making the first conductive component 1131 and the second conductive component 1132 electrically connected. The electric signal responding unit 115 obtains a 3.3V voltage. Based on the voltage change, it can be determined whether the cartridge 150 is installed to the predetermined position in the accommodation cavity 112.
Similarly, if the first conductive component 1131 is connected to a 3.3V voltage and the second conductive component 1132 is connected to a 0V voltage, the electric signal responding unit 115 is electrically connected to the first conductive component 1131. It can be understood that when the cartridge 150 is not installed to the predetermined position in the accommodation cavity 112, the first conductive component 1131 and the second conductive component 1132 are electrically isolated. The electric signal responding unit 115 obtains a 3.3V voltage. When the cartridge 150 is installed to the predetermined position in the accommodation cavity 112, the electric signal triggering assembly 152 is electrically connected to the first conductive component 1131 and the second conductive component 1132 respectively, thereby making the first conductive component 1131 and the second conductive component 1132 electrically connected. The electric signal responding unit 115 obtains a 0V voltage. Based on the voltage change, it can be determined whether the cartridge 150 is installed to the predetermined position in the accommodation cavity 112.
In embodiments of the present disclosure, the electrical connection in “the electric signal triggering assembly 152 is electrically connected to the first conductive component 1131 and the second conductive component 1132 respectively” can be a contact electrical connection or a non-contact electrical connection. For example, the non-contact electrical connection can be achieved through the principle of electromagnetic conversion, etc., and embodiments of the present disclosure do not limit this.
In one implementation, the frame 111 includes a top plate and a side plate that are adjacently arranged. The first conductive component 1131 and the second conductive component 1132 are arranged on the top plate, and the electric signal responding unit 115 is arranged on the side plate.
Referring to
Similarly, in other embodiments, the second conductive component 1132 of the main body 110 of the image forming apparatus can also be electrically connected to the power supply unit through the pull-up resistor. The first conductive component 1131 is grounded. Thus, when the electric signal triggering assembly 152 is electrically connected to the first conductive component 1131 and the second conductive component 1132, the electric signal responding unit obtains a high-level signal. Thus, it can determine that the installation of the cartridge 150 meets the expectation, that is, it is installed in place.
In embodiments of the present disclosure, the electrical connection in “the first conductive sheet 1521 is electrically connected to the first conductive component 1131, and the second conductive sheet 1522 is electrically connected to the second conductive component 1132” can be a contact electrical connection or a non-contact electrical connection. For example, the non-contact electrical connection can be achieved through the principle of electromagnetic conversion, etc., and embodiments of the present disclosure do not limit this.
In one implementation, the first conductive component 1131 and the second conductive component 1132 respectively include a metal conductive sheet or a plurality of metal conductive sheets electrically connected to each other. Further, when the first conductive component 1131 and the second conductive component 1132 are respectively two metal conductive sheets and electrically connected to each other, the two metal conductive sheets form a V-shape after contact. Alternatively, the shape of the first conductive component 1131 and the second conductive component 1132 can be a regular shape or an irregular shape, which is not limited in embodiments of the present disclosure.
In one implementation, the first conductive sheet 1521 and the second conductive sheet 1522 respectively include one metal conductive sheet or a plurality of metal conductive sheets electrically connected to each other. Further, when the first conductive sheet 1521 and the second conductive sheet 1522 are respectively two metal conductive sheets and electrically connected to each other, the two metal conductive sheets form a V-shape after contact. Alternatively, the shape of the first conductive sheet 1521 and the second conductive sheet 1522 can a regular shape or an irregular shape. Embodiments of the present disclosure do not limit it.
The conductive unit 113 and the electric signal triggering assembly 152 that matches with each other in the above technical solution are exemplarily described below in conjunction with the specific structure of the image forming apparatus 100.
It should be noted that
In one implementation, the assembly unit 151 on the cartridge 150 and the matching unit 114 on the main body 110 of the image forming apparatus can adopt mutually matching groove and protrusion structures. For example, in
Based on the same principle, the assembly unit 151 on the cartridge 150 can also be arranged as a second groove. The matching unit 114 on the main body 110 of the image forming apparatus can be arranged as a second protrusion. Through the matching of the second groove and the second protrusion, the cartridge 150 can be installed to a predetermined position in the accommodation cavity 112. The specific content can be referred to the description of the above embodiment, and will not be repeated here.
Corresponding to the protective component 117, an opening component 153 is also provided on the cartridge 150. When the cartridge 150 is installed to a predetermined position in the accommodation cavity 112, the opening component 153 can trigger the protective component 117 to release the cover of the conductive unit 113. This makes the electric signal triggering assembly 152 to be electrically connected to the conductive unit 113, triggering the electric signal responding unit 115 to obtain a predetermined responding signal.
Please continue to refer to
Specifically, one end of the elastic component 1173 contacts the conductive unit bracket 1130. The other end of the elastic component 1173 contacts the blocking component. When the elastic component 1173 does not have additional external forces, under the elastic force of the elastic component 1173, the elastic component 1173 covers at least a portion of the conductive unit 113. In embodiments of the present disclosure, since the conductive unit 113 includes two conductive components (a first conductive component 1131 and a second conductive component 1132), the blocking component includes two blocking parts 1571 to cover the first conductive component 1131 and the second conductive component 1132, respectively, as shown in the state shown in
Please continue to refer to
Specifically, the pressing part 1531 can be an inclined rib arranged on the housing 1500 of the cartridge 150. During the process of inserting the cartridge 150 into the accommodation cavity 112, the width of the inclined rib gradually increases, thereby pushing the matching part 1172. This makes the elastic component 1173 is further compressed, and drives the blocking part 1571 to gradually release the cover on the conductive unit 113.
For ease of understanding, the movement process of the pressing part 1531 and the matching part 1172 matching with each other is described below with reference to the accompanying drawings.

In addition, four imaging assembly accommodation cavities 116Y-K are provided on the main body 110 of the image forming apparatus. The four imaging assembly accommodation cavities 116Y-K are used to accommodate four imaging assemblies corresponding to different colors. Specifically, the four imaging assembly accommodation cavities 116Y-K are respectively a yellow imaging assembly accommodation cavity 116Y, a magenta imaging assembly accommodation cavity 116M, a cyan imaging assembly accommodation cavity 116C, and a black imaging assembly accommodation cavity 116K. The four imaging assembly accommodation cavities 116Y-K are respectively used to accommodate a yellow imaging assembly, a magenta imaging assembly, a cyan imaging assembly, and a black imaging assembly.
It is understandable that if the cartridges 150Y˜K of different colors and imaging assemblies of different colors are installed in the correct accommodation cavities 112Y˜K. In the process of performing the image forming operation, the toner in the cartridges 150Y˜K will be supplied to the imaging assemblies of the corresponding color, thereby completing the image forming operation. However, in order to reduce cost, the cartridges 150Y˜K corresponding to different colors are usually set to the same structure according to a standardized processing method. Therefore, when the user installs cartridges 150Y˜K of multiple colors, the installation order may be confused. For example, the magenta cartridge 150M is installed in the cyan accommodation cavity 112C, the cyan cartridge 150C is installed in the magenta accommodation cavity 112M. In this case, the magenta toner will be supplied to the cyan imaging assembly, the cyan toner will be supplied to the magenta imaging assembly, resulting in development degradation or image quality degradation, and affecting the user experience.
To address the issue, in one implementation, when multiple cartridges 150 need to be installed on the main body 110 of the image forming apparatus, assembly units 151 and pressing parts 1531 of the multiple cartridges 150 are arranged at different positions on the cartridges 150. Accordingly, the matching units 114 and the matching parts 1172 in the multiple accommodation cavities 112 are arranged at different positions on the main body 110 of the image forming apparatus. This arrangement can ensure that each cartridge 150 can only be installed in a designated accommodation cavity 112. This avoids confusion in the installation order of the cartridges 150 of multiple colors, which results in development degradation or image quality degradation.
In addition, when multiple cartridges 150 need to be installed on the main body 110 of image forming apparatus, a corresponding electric signal triggering assembly 152 is provided on each cartridge 150, and a corresponding conductive unit 113 is provided in each accommodation cavity 112, as shown in
Referring to
Step S1401: Obtaining a predetermined responding signal corresponding to the cartridge 150.
In a specific implementation, when a plurality of cartridges 150 is installed on the image forming apparatus 100, the predetermined responding signal corresponding to each cartridge 150 can be obtained respectively. For example, when the image forming apparatus 100 is installed with a yellow cartridge 150Y, a magenta cartridge 150M, a cyan cartridge 150C, and a black cartridge 150K, respectively, predetermined responding signals corresponding to the yellow cartridge 150Y, the magenta cartridge 150M, the cyan cartridge 150C, and the black cartridge 150K are respectively obtained.
In addition, when a plurality of cartridges 150 is installed on the image forming apparatus 100, the predetermined responding signals corresponding to different cartridges 150 can be the same or different, and embodiments of the present disclosure do not limit this. Of course, in some embodiments, the predetermined responding signals corresponding to different cartridges 150 are the same, to reduce the complexity of hardware circuit or software program design.
Step S1402: Determining whether the installation of the cartridge 150 meets an expectation based on the predetermined responding signal.
In a specific implementation, it can be determined whether a predetermined responding signal is received. If the predetermined responding signal is received, it is determined that the installation of the cartridge 150 meets the expectation. If the predetermined responding signal is not received, it is determined that the installation of the cartridge 150 does not meet the expectation.
In addition, when a plurality of cartridges 150 is installed on the image forming apparatus 100, it can be determined whether the installation of the cartridge 150 meets the expectation based on the predetermined responding signal corresponding to each cartridge 150. Exemplarily, when the image forming apparatus 100 is installed with a yellow cartridge 150Y, a magenta cartridge 150M, a cyan cartridge 150C, and a black cartridge 150K, respectively, it can be determined whether the yellow cartridge 150Y, the magenta cartridge 150M, the cyan cartridge 150C, and the black cartridge 150K meet the expectation based on the predetermined responding signals corresponding to the yellow cartridge 150Y, the magenta cartridge 150M, the cyan cartridge 150C, and the black cartridge 150K.
In embodiments of the present disclosure, a predetermined responding signal is used to determine whether the installation of the cartridge 150 meets the expectation, thereby avoiding the issue of development degradation or image quality degradation caused by improper installation of the cartridge 150.
In one implementation, when it is determined that the installation of the cartridge 150 does not meet expectations, a prompt signal indicating that the installation of the cartridge 150 is abnormal is output to prompt the user that the installation of the cartridge 150 is abnormal. Thus, the user can correct the abnormally installed cartridge 150. In a specific implementation, the prompt signal can be an image signal, an audio signal, or a fault indicator light, etc., which is not limited in embodiments of the present disclosure.
In addition, when a plurality of cartridges 150 is installed on the image forming apparatus 100, the prompt signal corresponding to each cartridge 150 may be different so that the user can distinguish which cartridge 150 has a malfunction.

Embodiments of the present disclosure also provide a cartridge assembly.
In one implementation, when the cartridge assembly is installed on the main body 110 of the image forming apparatus, the plurality of cartridges 150 is arranged in a row. Assembly units 151 and pressing parts 1531 of the plurality of cartridges 150 are disposed at different positions on the plurality of cartridges 150.
In addition, four imaging assembly accommodation cavities 116Y˜K are provided on the main body 110 of the image forming apparatus. The four imaging assembly accommodation cavities 116Y˜K are used to accommodate four imaging assemblies corresponding to different colors. Specifically, the four imaging assembly accommodation cavities 116Y˜K are respectively a yellow imaging assembly accommodation cavity 116Y, a magenta imaging assembly accommodation cavity 116M, a cyan imaging assembly accommodation cavity 116C, and a black imaging assembly accommodation cavity 116K. The four imaging assembly accommodation cavities 116Y˜K are respectively used to accommodate a yellow imaging assembly, a magenta imaging assembly, a cyan imaging assembly, and a black imaging assembly. Specifically, each of the imaging assemblies 116Y˜K includes a photosensitive drum, a cleaning blade, a discharger, a charging component, and a developing component. The charging component can make the surface of the photosensitive drum uniformly charged. An exposure component exposes and scans the photosensitive drum through a laser so that the uniformly charged surface of the photosensitive drum carries an electrostatic latent image. The electrostatic latent image is developed by the developing component and toner, then transferred to an intermediate transfer belt. After the transfer is completed, the cleaning blade removes the toner remaining on the surface of the photosensitive drum. The discharger removes the charge remaining on the photosensitive drum, making the photosensitive drum ready for the next imaging.
Please note that in the cartridge type shown in embodiments of the present disclosure, a photosensitive drum, a charging roller, and a developing device storing toner are integrated to form a cartridge. The cartridge is configured to be removable from the main body 110 of the image forming apparatus 100. Further, although the cartridge is described as an example above, the present disclosure does not limit it. For example, it can use a developing cartridge including toner and a developing device but not a photosensitive drum. Alternatively, it can use a toner cylinder that does not include a roller. In some embodiments, it can use a photosensitive drum cartridge that does not include a developing device but integrates a photosensitive drum and a charging roller.
