DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] In the description of this application, unless otherwise clearly specified and defined, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "plural" means two or more; the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the drawings and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0026] An embodiment of this application discloses an image forming apparatus, which includes an image forming apparatus main body and a processing cartridge (consumable). The image forming apparatus main body includes a processing cartridge mounting portion, and the processing cartridge is detachably mounted in the processing cartridge mounting portion. Among them, the processing cartridge includes at least one of a toner cartridge assembly, an imaging assembly, and a developing assembly.

[0027] In some embodiments, the toner cartridge assembly, the imaging assembly, and the developing assembly are integrally provided. The toner cartridge assembly is used to store toner and provide toner for the developing assembly. The imaging assembly and the developing assembly cooperate with each other to transfer the toner onto a recording material (such as paper) to form a desired pattern on the recording material. Specifically, the toner cartridge assembly includes a toner storage bin. The imaging assembly generally includes a photosensitive drum and a charging roller. The developing assembly generally includes a developing roller and a doctor blade. The developing roller rotates and adsorbs the toner in the toner storage bin onto its surface, and is leveled by the doctor blade so that the toner on the surface of the developing roller is evenly distributed. The photosensitive drum is arranged in cooperation with the developing roller. The charging roller is used to charge the surface of the photosensitive drum so that the surface of the photosensitive drum is charged with electricity. Then, an electrostatic latent image corresponding to the printed content is formed on the surface of the photosensitive drum by laser irradiation. The electrostatic latent image on the surface of the photosensitive drum can adsorb the toner on the surface of the developing roller, so that the toner adsorbed on the surface of the photosensitive drum can be arranged according to the printed content, and then the toner is transferred from the photosensitive drum onto the recording material to form a required pattern.

[0028] In some other embodiments, the toner cartridge assembly, the imaging assembly, and the developing assembly can also be separately provided. For example, the toner cartridge assembly, the imaging assembly, and the developing assembly can be separately provided, or the toner cartridge assembly is separately provided, and the imaging assembly and the developing assembly are integrally provided, or one of the imaging assembly and the developing assembly is integrally provided with the toner cartridge assembly, and the other is separately provided. Additionally, the photosensitive drum and the developing roller can be separately provided on the main body of the image forming apparatus, or one of the photosensitive drum and the developing roller can be provided in the processing cartridge, and the other can be provided on the main body of the image forming apparatus.

[0029] Since the printing process of the image forming apparatus involves multiple fittings between the consumables and the main body of the image forming apparatus, it is necessary to ensure the stable and accurate positions of all components. When replacing or maintaining the consumables, the consumables need to be taken out and then reinstalled. If the consumables are not installed correctly or stably in the printer, it may lead to abnormal printing effects or damage to the printer and the consumables. Therefore, it is necessary to ensure that the consumables are installed in place when installed in the printer.

[0030] Referring to Figure 1 and Figure 2 As shown, the main body of the image forming apparatus further includes a first detection unit 101, a second detection unit 102, and a controller. The first detection unit 101 and the second detection unit 102 are respectively provided in the processing installation part. The processing cartridge includes a main body 1, a first trigger unit 2, and a second trigger unit 3. The first trigger unit 2 and the second trigger unit 3 are respectively provided on the main body 1. The first trigger unit 2 is used to cooperate with the first detection unit 101 to trigger a first signal, and the second trigger unit 3 is used to cooperate with the second detection unit 102 to trigger a second signal, and the time point when the first trigger unit 2 triggers the first signal is different from the time point when the second trigger unit 3 triggers the second signal. The controller is used to receive the first signal and the second signal to confirm whether the processing cartridge is installed in place and issue a corresponding prompt sound or alarm.

[0031] In this embodiment, the time point when the second trigger unit 3 triggers the second signal is delayed by a preset time relative to the time point when the first trigger unit 2 triggers the first signal, so that the time point when the first trigger unit 2 triggers the first signal is different from the time point when the second trigger unit 3 triggers the second signal. Of course, in other embodiments, it can also be that the time point when the first trigger unit 2 triggers the first signal is delayed by a preset time relative to the time point when the second trigger unit 3 triggers the second signal, so that the time point when the first trigger unit 2 triggers the first signal is different from the time point when the second trigger unit 3 triggers the second signal.

[0032] Exemplarily, the preset time by which the time point when the second trigger unit 3 triggers the second signal is delayed relative to the time point when the first trigger unit 2 triggers the first signal can be 3 seconds, 4 seconds, 5 seconds, etc., and specifically, a suitable elastic member can be selected according to needs.

[0033] Reference Figure 3 As shown, the main body 1 includes a driving head, a first end portion 13 and a second end portion 14. The first end portion 13 and the second end portion 14 are two end portions of the main body in the axial direction of the stirring frame or the roller member ( Figure 3 the X direction in Figure 6 ). Referring to Figure 6 shown, in

[0034] In this embodiment, the first trigger unit 2 is fixedly arranged on the main body 1, and the second trigger unit 3 is movably arranged relative to the main body 1. It can be understood that in other embodiments, the first trigger unit 2 can also be movably arranged relative to the main body 1, the second trigger unit 3 is fixedly arranged on the main body 1, or both the first trigger unit 2 and the second trigger unit 3 are movably arranged relative to the main body 1.

[0035] Reference Figure 4 shown, the processing cartridge further includes a handle 15 and an elastic member (not shown in the figure). The handle 15 is movably connected to the main body 1. One end of the elastic member is connected to the handle 15, and the other end of the elastic member is connected to the main body 1, so that the handle 15 can displace relative to the main body 1 by compressing the elastic member. The second trigger unit 3 is arranged on the handle 15, so that the second trigger unit 3 can displace relative to the main body 1. Among them, the elastic member can be set as a spring.

[0036] Exemplarily, the second trigger unit 3 has a first position and a second position. During the process of installing the processing cartridge into the processing cartridge installation portion, the handle 15 is restricted by the image forming apparatus main body and compresses the elastic member. At this time, both the handle 15 and the second trigger unit 3 are in the first position. When the processing cartridge is installed in place, the first trigger unit 2 cooperates with the first detection unit 101 to trigger a first signal; the handle 15 moves to the second position under the action of the elastic restoring force of the elastic member, and when the second trigger unit 3 also moves from the first position to the second position, at this time, the handle 15 is engaged with the image forming apparatus main body, and the second trigger unit 3 cooperates with the second detection unit 102 to trigger a second signal. And because it takes a certain amount of time for the second trigger unit 3 to move from the first position to the second position, therefore, the time point when the second trigger unit 3 triggers the second signal is delayed by a preset time relative to the time point when the first trigger unit 2 triggers the first signal.

[0037] In this embodiment, the triggering times of the two triggering units are made different by displacement. In other embodiments, when it is necessary to supply electric energy to the two triggering units or make the two triggering units electrically conductive, the power-on times of the two triggering units can be made different so that the triggering times of the two triggering units are different. For example, when the processing cartridge is installed in place, the power supply of the first triggering unit can be turned on first to make the first triggering unit trigger the first signal, and after a certain delay, the power supply of the second triggering unit is turned on to make the second triggering unit trigger the second signal. Alternatively, the power supply of the second triggering unit can be turned on first to make the second triggering unit trigger the second signal, and after a certain delay, the power supply of the first triggering unit is turned on to make the first triggering unit trigger the first signal.

[0038] Continue to refer to Figure 2 As shown, the image forming apparatus main body includes an inner front cover 105. The inner front cover 105 is provided with a engaged portion, and the processing cartridge mounting portion is provided with a guiding slideway 103. Both the first end portion 13 and the second end portion 14 are provided with guided portions, and the guided portions are arranged in cooperation with the guiding slideway 103. The main body 1 further includes a developer container 11, a waste toner bin 12, and a stirring frame. The developer container 11 is used to store toner for supplying to the developing roller. The waste toner bin 12 is mainly used to collect and store the waste toner generated by the imaging component during the printing process. Among them, the developer container 11 and the waste toner bin 12 can be integrally provided or separately provided. The stirring frame is arranged in the developer container 11 and is used to stir the toner in the developer container 11 so that the toner can be output more smoothly. The handle 15 is connected to the waste toner bin 12, and the handle 15 is arranged corresponding to the engaged portion. The first triggering unit 2 is arranged in the developer container 11, and the second triggering unit 3 is arranged on the handle 15, that is, the second triggering unit 3 is indirectly arranged on the waste toner bin 12.

[0039] When the main body 1 is installed in the processing cartridge mounting portion along the installation direction ( Figure 3 the Y direction in ), the first end portion 13 and the second end portion 14 of the processing cartridge are respectively inserted into the processing cartridge mounting portion, so that the guided portions are engaged with the guiding slideway 103 for limiting, and the main body 1 is guided to move along the extending direction of the guiding slideway 103 to the installation position; when the main body 1 moves to the installation position, the first triggering unit 2 cooperates with the first detection unit 101 to trigger the first signal; the handle 15 moves from the first position to the second position under the elastic restoring force of the elastic member, and the second triggering unit 3 also moves from the first position to the second position along with the handle 15. At this time, the handle 15 is snapped into the engaged portion to limit the processing cartridge, and the second triggering unit 3 cooperates with the second detection unit 102 to trigger the second signal.

[0040] In some embodiments, the first trigger unit 2 can be fixed to the lower surface of the developer container 11 by a snap-fit manner, and the first detection unit 101 can be fixed to the guiding slideway 103 by a snap-fit manner. The second trigger unit 3 can be fixed to the handle 15 by a snap-fit manner, and the second detection unit 102 can be fixed to the inner plate 105 of the front cover by a snap-fit manner.

[0041] In this embodiment, the first trigger unit 2 can be set as a magnetic member, and the first detection unit 101 can be set as a magnetic sensor such as a Hall element or a reed switch. When the magnetic member approaches the magnetic sensor, a signal is output through magnetic induction. In other embodiments, the first trigger unit 2 can also be set as a light-emitting element, and the first detection unit 101 can also be set as a light sensor such as an infrared sensor. When the light-emitting element approaches the light sensor, a signal is output through light induction. Of course, the second trigger unit can also be set as a magnetic member or a light-emitting element, and the second detection unit can also be correspondingly set as a magnetic sensor or a light sensor. Or, the first trigger unit and the second trigger unit can be set as light sensors or magnetic sensors, and the first detection unit and the second detection unit can be set as magnetic members or light-emitting elements.

[0042] In this embodiment, one of the first trigger unit 2 and the first detection unit 101 is set as a first magnet, and the other of the first trigger unit 2 and the first detection unit 101 is set as a first magnetic induction switch, and the first magnetic induction switch is arranged corresponding to the position of the first magnet. One of the second trigger unit 3 and the second detection unit 102 is set as a second magnet, and the other of the second trigger unit 3 and the second detection unit 102 is set as a second magnetic induction switch, and the second magnetic induction switch is arranged corresponding to the position of the second magnet. When the processing cartridge is installed in the processing cartridge installation part and installed in place, the first magnetic induction switch senses the magnetic signal generated by the first magnet and thus emits a first signal, and the second magnetic induction switch senses the magnetic signal generated by the second magnet and thus emits a second signal.

[0043] Specifically, the first detection unit 101 can be installed on the guiding slideway 103, and the second detection unit 102 can be installed on the inner plate 105 of the front cover. The first trigger unit 2 is connected to the developer container 11 and is located on the lower surface of the developer container 11, and the second trigger unit 3 is connected to the handle 15. When the processing cartridge is installed and installed in place, the first detection unit 101 is located directly below the first trigger unit 2, so that the first trigger unit 2 and the first detection unit 101 interact with each other, thereby emitting a first signal. At the same time, under the action of the elastic member, the second trigger unit 3 moves from the first position to the second position along with the handle 15. At this time, the second detection unit 102 is located directly above the second trigger unit 3, so that the second trigger unit 3 and the second detection unit 102 interact with each other, thereby emitting a second signal. After receiving the first signal and the second signal, the controller determines whether the processing cartridge is installed in place based on the delay time of the second signal relative to the first signal.

[0044] In some embodiments, with reference to Figure 5 as shown, the guiding slideway 103 may be provided with a first limiting groove 104, the first limiting groove 104 may be provided with a first buckle, the developer accommodating member 11 may be provided with a second limiting groove 111, and the second limiting groove 111 may be provided with a second buckle. The first detection unit 101 may be installed in the first limiting groove 104 and fixed in the first limiting groove 104 by the first buckle. The first trigger unit 2 may be installed in the second limiting groove 111 and fixed in the second limiting groove 111 by the second buckle. In this embodiment, the first detection unit 101 is fixed to the guiding slideway 103 by a clamping manner, and the first trigger unit 2 is fixed to the developer accommodating member 11 by a clamping manner, so that the first detection unit 101 can be more stably installed on the guiding slideway 103, and the first trigger unit 2 can be more stably installed on the developer accommodating member 11, because if the first detection unit and the first trigger unit are fixed by means such as bonding, the bonding may become loose due to heat.

[0045] In some embodiments, the inner front cover 105 may be provided with a third limiting groove, the third limiting groove may be provided with a third buckle, the handle 15 may be provided with a fourth limiting groove, and the fourth limiting groove may be provided with a fourth buckle. The second detection unit 102 may be installed in the third limiting groove and fixed in the third limiting groove by the third buckle. The second trigger unit 3 may be installed in the fourth limiting groove and fixed in the fourth limiting groove by the fourth buckle. In this embodiment, the second detection unit 102 is fixed to the inner front cover 105 by a clamping manner, and the second trigger unit 3 is fixed to the handle 15 by a clamping manner, so that the second detection unit 102 can be more stably installed on the inner front cover 105, and the second trigger unit 3 can be more stably installed on the handle 15, because if the second detection unit 102 and the second trigger unit 3 are fixed by means such as bonding, the bonding may become loose due to heat.

[0046] In some embodiments, the processing cartridge further includes a driving head and an information processing device (the information processing device may be a chip). The driving head is used for driving transmission with the image forming apparatus main body. The information processing device includes a substrate and a plurality of functional contacts. The substrate is disposed on the main body 1, the functional contacts are distributed on the upper surface of the substrate, and the functional contacts extend along a first direction ( Figure 3They are arranged in sequence in the Y direction (in the Y direction in the figure), and the functional contacts are used to contact the stylus of the image forming apparatus main body to achieve electrical connection. The first trigger unit 2 and the second trigger unit 3 are respectively arranged on both sides of the main body 1 in the Z direction. In other words, the first trigger unit 2 and the second trigger unit 3 are respectively arranged on both sides of the reference plane. The axis line of the driving head is located in the reference plane, and the reference plane is parallel to the first direction. That is, the reference plane is a plane passing through the axis line of the driving head and parallel to the plane where the X axis and the Y axis are located.

[0047] In an actual application scenario, the user can hold the processing cartridge by hand and push the first end 13 and the second end 14 of the processing cartridge into the processing cartridge installation part of the image forming apparatus at the same time. During the installation process of the processing cartridge, the first trigger unit 2 and the second trigger unit 3 move along with the movement of the main body 1. When the processing cartridge is installed in place, the first trigger unit 2 cooperates with the first detection unit 101 to trigger the first signal; when the handle 15 moves to the second position under the action of the elastic restoring force of the elastic member and the second trigger unit 3 also moves from the first position to the second position, at this time, the handle 15 is snapped into the engaged part to realize the limit of the processing cartridge, and the second trigger unit 3 cooperates with the second detection unit 102 to trigger the second signal. After the controller receives the first signal and the second signal within a preset interval time, it confirms that the processing cartridge is installed in place and can emit a prompt sound indicating that the processing cartridge is installed in place. Otherwise, it emits an alarm indicating that the processing cartridge is installed incorrectly. For example, if the controller does not receive any signal, or only receives the first signal or the second signal, it is confirmed that the processing cartridge is not installed in place.

[0048] Through the settings of the first trigger unit 2 and the second trigger unit 3 in this application, the problem in the related art that it is impossible to determine whether the processing cartridge is installed in place can be solved, and the trigger unit must be installed within a specific detection range of the processing cartridge, otherwise the trigger unit and the detection unit cannot interact with each other to output a signal, thus realizing anti-compatibility.

[0049] The above is only the preferred specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
