Description

Technical field

[0001] The embodiments of the present invention relate to the field of electronic imaging technology, and in particular to a de-charge method, a de-charge structure, a consumable material box, and an image forming device. [Background Technology]

[0002] With the development of electronic imaging technology, image forming devices have become widely used. Consumable cartridges are detachably mounted on image forming devices. Consumable cartridges may include an optical photoconductor (OPC) component, which is a photosensitive drum. As image forming devices are used over time, the OPC component is prone to light fatigue, meaning that residual charge remains on the surface of the OPC component. If this residual charge is not promptly removed, ghosting may occur during printing, resulting in poor image quality.

[0003] In order to solve the problem of ghosting during the printing process, a de-electrification component can be set in the consumable box, and the residual charge on the surface of the OPC component can be de-electrified by the de-electrification component. In the prior art, the de-electrification lamp of the de-electrification component is an active de-electrification lamp. The active de-electrification lamp requires an additional power supply to drive the light-emitting diode (LED), which takes up a large space. When the image forming device de-electrifies the photosensitive component, the photosensitive component will rotate, and the rotation speed of the photosensitive component will affect the degree of de-electrification of the de-electrification lamp. If the light intensity of the de-electrification lamp is set unreasonably, or because the rotation speed of the photosensitive component is not an ideal control speed, the light intensity of the de-electrification lamp cannot match the rotation speed of the photosensitive component, which will cause excessive de-electrification or insufficient de-electrification of the photosensitive component. For example, if the photosensitive component rotates too slowly, the cleaning lamp will over-discharge the photosensitive component, causing light fatigue such as overcharging and over-discharging, shortening the photosensitive component's lifespan. If the photosensitive component rotates too fast, the cleaning lamp will not fully discharge the photosensitive component, causing ghosting in the printed image and reducing the print quality. Therefore, the cleaning lamp and the photosensitive component cannot achieve matching cleaning. [Summary of the invention]

[0004] In view of this, embodiments of the present invention provide a de-electrification method, a de-electrification structure, a consumable material box, and a pattern forming device, so as to reduce the occupied space of the de-electrification structure and achieve matching de-electrification between the de-electrification structure and the photosensitive component.

The de-electrification device can de-electrify the photosensitive element without the need for an additional power supply, thereby reducing the space occupied by the de-electrification structure. The de-electrification structure has a simple structure and adopts a passive design, and does not require external power supply. When the magnetic induction element and the magnetic element are relatively displaced, the magnetic induction element generates an induced current to drive the de-electrification device to de-electrify. Therefore, the de-electrification degree of the de-electrification device changes with the speed of the relative displacement of the magnetic induction element and the magnetic element, thereby achieving matching between the speed of the relative displacement of the magnetic induction element and the magnetic element and the de-electrification degree, effectively preventing the de-electrification structure from excessively or insufficiently de-electrifying the photosensitive element, and thereby achieving matching de-electrification between the de-electrification structure and the photosensitive element.

[0044] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0046] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0047] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0048] Figure 1 A schematic diagram of a de-energizing structure provided by an embodiment of the present invention is shown. Figure 2 for Figure 1 Schematic diagram of the structure of the magnetic induction component and the de-static component. Figure 3 A schematic structural diagram of a consumables box provided by an embodiment of the present invention is shown in FIG. Figure 1 、 Figure 2 and Figure 3 As shown, the de-electrification structure includes a de-electrification device 1 and at least one magnetic induction element 2. The magnetic induction element 2 is configured to move relative to the magnetic element 21, causing the magnetic induction element 2 to generate an induced current. The de-electrification device 1 is electrically connected to the magnetic induction element 2. The magnetic induction element 2 transmits the induced current to the de-electrification device 1, which is used to de-electrify the photosensitive component 20.

[0049] The de-electrification device 1 can de-electrify the photosensitive component 20 in various ways. Alternatively, the de-electrification device 1 can de-electrify the photosensitive component 20 by exposing the photosensitive component 20 to light. Specifically, the de-electrification device 1 is a de-electrification lamp. When the magnetic induction element 2 transmits an induced current to the de-electrification device 1, the de-electrification device 1 emits light and de-electrifies the photosensitive component 20. Alternatively, the de-electrification device 1 can reverse-electrify the photosensitive component 20 to eliminate any residual charge on the photosensitive component 20. In the embodiments of the present invention, the de-electrification device 1 is described as a de-electrification lamp.

[0050] like Figure 1 and Figure 3As shown, the de-electrification structure also includes a light guide 301. The de-electrification device 1 is arranged opposite to the light guide 301. The light guide 301 is used to transmit the light emitted by the de-electrification device 1 to the photosensitive component 20 and to be used for de-electrification. The light guide 301 is used to be arranged along the axial direction of the photosensitive component 20. The light guide 301 is arranged opposite to the photosensitive surface of the photosensitive component 20. Since the shape of the photosensitive component 20 is a cylinder, the photosensitive surface of the photosensitive component 20 is the side of the cylinder. The material of the light guide 301 may include polymethyl methacrylate (PMMA), polycarbonate (PC) or polyurethane (PU). In the embodiment of the present invention, the shape of the light guide 301 can be set to be flat, which reduces the occupied space, thereby further realizing the miniaturized design of the consumable box. In an embodiment of the present invention, the light guide 301 adopts a strip-shaped structure, that is, the light guide 301 can be a light guide strip. Compared with the solution of using a light guide column in the prior art, a flat light guide strip is used instead of the light guide column, and there is no need to add a matching hole for placing the light guide column on the consumable box, thereby further realizing the miniaturization design of the consumable box.

[0051] like Figure 1 and Figure 3 As shown, a plurality of light guide points are provided on the side of the light guide 301 close to the photosensitive component, and the light guide points include protrusions and / or depressions. The light guide points are integrally formed with the light guide 301. The function of the light guide points is to convert the incident light into a surface light source after being refracted countless times in the light guide 301, and then the light is uniformly emitted from the side of the light guide 301 close to the photosensitive component 20 and irradiates the surface of the photosensitive component 20, thereby realizing the light refracted and diffused into a uniform light state of the surface light source in the light guide 301, so that the coating on the photosensitive surface of the photosensitive component 20 is evenly charged and discharged, thereby extending the service life of the photosensitive component 20. As shown Figure 1 and Figure 3 As shown, the de-charge structure also includes a lens 302, which is located between the de-charge device 1 and the light guide 301. The lens 302 includes a light-inlet end and a light-collecting end. The lens 302 is used to collect light entering from the light-inlet end to the light-collecting end for output. The light-inlet end is used to receive light emitted by the de-charge device 1, and the light-collecting end is used to output the light to the light guide 301. The light guide 301 guides light so that it illuminates the photosensitive surface of the photosensitive component 20. After being illuminated, the residual charge on the photosensitive surface of the photosensitive component 20 is evenly guided away, thereby achieving de-charge of the residual charge on the photosensitive surface of the photosensitive component 20. In this embodiment of the present invention, the structures of the de-charge device 1, lens 302, and light guide 301 are almost completely aligned, thereby preventing light leakage.

[0052] like Figure 1 and Figure 3As shown, a reflective film 303 is provided on the side of the light guide 301 facing away from the photosensitive component 20. This film 303 is used to reflect light. This film 303 reflects back any light within the light guide 301 that is not directed toward the photosensitive component 20, allowing the light guide 301 to direct as much light as possible onto the photosensitive component 20, thereby enhancing the light intensity on the photosensitive surface of the photosensitive component 20. Furthermore, if light escapes from the light guide 301, it could lead to abnormal exposure of the photosensitive component 20 and produce print defects. In this embodiment of the present invention, the reflective film 303 is provided on one side of the light guide 301 to reflect light back into the light guide 301, effectively preventing light from escaping and thus avoiding print defects caused by abnormal exposure of the photosensitive component 20.

[0053] like Figure 2 As shown, the de-static structure further includes a driving circuit 4 , and the magnetic induction component 2 is electrically connected to the de-static device 1 via the driving circuit 4 .

[0054] like Figure 1 、 Figure 2 and Figure 3 As shown, the de-static structure further includes a carrier 3, and the magnetic induction element 2 and the de-static device 1 are both arranged on the carrier 3. Figure 2 As shown, the magnetic induction element 2 and the driving circuit 4 are arranged on the carrier 3, the positive phase terminal (+) and the negative phase terminal (-) of the magnetic induction element 2 are connected to the input terminal of the driving circuit 4, and the output terminal of the driving circuit 4 is connected to the de-static device 1.

[0055] like Figure 1 、 Figure 2 and Figure 3 As shown, the carrier 3 includes a main body 31 and an extension 32 extending from the main body 31. The magnetic induction element 2 is disposed in the main body 31, and the drive circuit 4 is disposed in the extension 32. Part of the extension 32 is disposed in the main body 31, while another portion of the extension 32 extends beyond the main body 31. The neutralization device 1 is disposed at one end of the extension 32 that extends beyond the main body 31. Therefore, the neutralization device 1 is disposed outside the main body 31, and the position of the neutralization device 1 can be adjusted by adjusting the length of the extension 32.

[0056] like Figure 2 As shown, there are multiple magnetic induction members 2, which are arranged around the center point of the main body 31 and arranged in sequence along the circumference of the center point of the main body 31. The shape of the main body 31 can be set according to the product design requirements. For example, the cross-sectional shape of the main body 31 can be circular or square, such as Figure 1 As shown, in the embodiment of the present invention, in order to match the shape of the driving component of the photosensitive component 20, the cross-section of the main body portion 31 is circular. Preferably, Figure 2Six magnetic induction elements 2 are shown, and the six magnetic induction elements 2 are arranged around the center point of the main body portion 31 and arranged in sequence along the circumference of the center point of the main body portion 31. Each magnetic induction element 2 includes a positive phase terminal (+) and a negative phase terminal (-), and the positive phase terminal (+) and the negative phase terminal (-) of each magnetic induction element 2 are connected to the input terminal of the drive circuit 4. It should be noted that: Figure 2 The connection lines between the positive phase terminal (+) and the negative phase terminal (-) of the magnetic induction element 2 and the driving circuit 4 are not specifically drawn.

[0057] like Figure 1 、 Figure 2 and Figure 3 As shown, carrier 3 is a flexible printed circuit (FPC), and both main body 31 and extension 32 are FPC. The magnetic induction element 2 is a magnetic induction coil, with multiple printed circuit board (PCB) coils uniformly and densely etched on main body 31, and these PCB coils serve as magnetic induction coils. The drive circuit 4 can be miniaturized and mounted on extension 32. In this embodiment of the present invention, the use of a flexible circuit board allows for a flat design of the dissipation device 1, thereby reducing the structural space of the consumables box.

[0058] like Figure 2 As shown, the drive circuit 4 includes a rectifier and filter circuit. The magnetic induction element 2 generates an induced electromotive force E. For example, multiple magnetic induction elements 2 can generate n induced electromotive forces, including induced electromotive forces E1, E2, ..., En, where n is a positive integer. The rectifier and filter circuit rectifies and filters the induced electromotive force generated by the magnetic induction element 2 to form a DC supply voltage, which is then output to the de-energizing device 1. Driven by the DC supply voltage, the de-energizing device 1 emits light. Optionally, the de-energizing device 1 is an LED.

[0059] In the technical solution of the de-electrification structure provided by the embodiment of the present invention, the magnetic induction member generates an induced current by relative displacement with the magnetic member, and the de-electrification device de-electrifies the photosensitive member through the induced current generated by the magnetic induction member. No additional power supply is required to enable the de-electrification device to de-electrify the photosensitive member, thereby reducing the occupied space of the de-electrification structure. The de-electrification structure has a simple structure and adopts a passive design, and does not require external power supply. When the magnetic induction member and the magnetic member are relatively displaced, the magnetic induction member generates an induced current to drive the de-electrification device to de-electrify. Therefore, the de-electrification degree of the de-electrification device changes with the speed of the relative displacement of the magnetic induction member and the magnetic member, thereby achieving matching between the speed of the relative displacement of the magnetic induction member and the magnetic member and the de-electrification degree, effectively preventing the de-electrification device from excessively or insufficiently de-electrifying the photosensitive member, and thereby achieving matched de-electrification of the de-electrification device and the photosensitive member.

[0060] An embodiment of the present invention provides a consumables box, which can be detachably mounted on an image forming device, such as Figure 3 As shown, the consumables box includes a de-electrification structure and a photosensitive component 20. The photosensitive component 20 or a rotating component that cooperates with the photosensitive component 20 is provided with at least one magnetic component 21. The magnetic induction component 2 is arranged relative to the magnetic component 21 and can move relative to it. The de-electrification device 1 is used to de-electrify the photosensitive surface of the photosensitive component 20. The description of the de-electrification structure can be found in Figures 1 to 3 In the embodiment of the present invention, the magnetic member 21 may include a permanent magnet or an electromagnet.

[0061] As an optional solution, at least one magnetic member 21 may be disposed on the photosensitive component 20 . For example, at least one magnetic member 21 may be located at the first end of the photosensitive component 20 .

[0062] As another optional solution, at least one magnetic member 21 may be provided on the rotating member, and the rotating member may include a driving member 22. The magnetic member 21 is provided on the driving member 22, and the driving member 22 rotates synchronously with the photosensitive member 20, thereby achieving transmission cooperation with the photosensitive member 20. Figure 4 A schematic diagram of the structure of a driving component provided by an embodiment of the present invention is shown in FIG. Figure 3 and Figure 4 As shown, the driving component 22 is arranged at the first end of the photosensitive component 20, and the magnetic component 21 is arranged on the driving component 22. The center point of the carrier 3 and the center point of the driving component 22 are both located on the extension line of the center line of the photosensitive component 20. The photosensitive component 20 is a photosensitive drum, and the shape of the photosensitive component 20 is cylindrical; the driving component 22 is a gear, and the shape of the driving component 22 is also cylindrical to match the shape of the photosensitive component 20. In actual applications, the photosensitive component 20 and the driving component 22 can also be set to other shapes, which are not listed here one by one. Figure 4 As shown, the number of magnetic members 21 provided on the driving member 22 can be multiple. As an optional solution, the multiple magnetic members 21 are evenly arranged around the center point of the driving member 22. Figure 3 Eight magnetic members 21 are shown in the figure, and the eight magnetic members 21 are evenly arranged around the center point of the driving member 22. The number of magnetic members 21 and the number of magnetic induction members 2 can be the same or different. In the embodiment of the present invention, eight magnetic members 21 and six magnetic induction members 2 are used as an example for description. Figure 3 and Figure 4 As shown, the magnetic part 21 can be embedded in the driving part 22. When the driving part 22 rotates, the magnetic part 21 and the photosensitive part 20 rotate around the same axis. When the magnetic part 21 rotates, a magnetic field is generated. The magnetic induction part 2 cuts the magnetic field to generate an induced electromotive force, that is, the magnetic induction part 2 cuts the magnetic field to generate an induced current.

[0063] like Figure 3 As shown, the carrier 3 is arranged relative to the first end of the photosensitive component 20 so that the magnetic induction component 2 and the magnetic component 21 are arranged relative to each other. Specifically, the main body 31 of the carrier 3 is arranged relative to the first end of the photosensitive component 20 so that the magnetic induction component 2 and the magnetic component 21 are arranged relative to each other. The end of the extension part 32 of the carrier 3 provided with the de-electrification device 1 extends to the light entrance of the light guide 301 so that the de-electrification device 1 is arranged at the light entrance of the light guide 301. It should be noted that: the magnetic induction component 2 is arranged at the light entrance of the light guide 301. Figure 3 Not specifically drawn in the figure.

[0064] In the embodiment of the present invention, as an optional solution, Figure 3 As shown, the consumables box also includes a cleaning scraper, which includes a transparent adhesive strip 304 and a metal part. The transparent adhesive strip 304 is set on the side of the light guide 301 close to the photosensitive component 20. For example, the material of the transparent adhesive strip 304 is PU. The light emitted from the light guide 301 is irradiated to the surface of the photosensitive component 20 through the transparent adhesive strip 304. It should be noted that: the metal part is Figure 3 It is not specifically drawn in the figure, and the location of the metal parts does not affect the propagation of light.

[0065] In the technical solution of the consumable box provided by the embodiment of the present invention, the magnetic induction component generates an induced current by relative displacement with the magnetic component, and the de-electrification device de-electrifies the photosensitive component through the induced current generated by the magnetic induction component. The de-electrification device can de-electrify the photosensitive component without the need for additional power supply, thereby reducing the space occupied by the de-electrification structure, and the structure of the de-electrification structure is simple, adopts a passive design, and does not require external power supply; when the magnetic induction component and the magnetic component are relatively displaced, the magnetic induction component generates an induced current to drive the de-electrification device to de-electrify, therefore, the de-electrification degree of the de-electrification device changes with the speed of the relative displacement of the magnetic induction component and the magnetic component, thereby achieving matching of the speed of the relative displacement of the magnetic induction component and the magnetic component with the de-electrification degree, effectively preventing the de-electrification structure from excessive or insufficient de-electrification of the photosensitive component, and thereby achieving matching de-electrification of the de-electrification structure and the photosensitive component.

[0066] The embodiment of the present invention provides an image forming device, which includes an image forming device body and a consumables box. The description of the consumables box can be found in Figure 3 and Figure 4 The description of the embodiments in the embodiment will not be repeated here.

[0067] An embodiment of the present invention provides another image forming device, which includes an image forming device body and a de-electrification structure. The magnetic induction element is provided on the image forming device body; or the de-electrification structure is provided on the image forming device body. The description of the de-electrification structure can be found in Figures 1 to 3 The description of the embodiments in the embodiment will not be repeated here.

[0068] In the field of printing and imaging, examples of image forming devices include inkjet printers, laser printers, LED printers, copiers, scanners, or multifunction fax machines, as well as multifunction peripherals (MFPs) that perform the above functions in a single device. An image forming device includes an image forming control unit and an image forming unit. The image forming control unit is used to control the image forming device as a whole, and the image forming unit is used to form an image on a conveyed sheet of paper under the control of the image forming control unit based on image formation data and developer, such as toner, stored in a consumables cartridge.

[0069] In the field of printing and imaging, consumable cartridges are used to hold developers. For example, if the consumable cartridge is an ink cartridge and the developer is ink, then the ink cartridge holds ink; if the consumable cartridge is a toner cartridge and the developer is toner, then the toner cartridge holds toner; if the consumable cartridge is a powder cartridge or toner cartridge and the developer is toner, then the powder cartridge holds toner, and the toner cartridge holds toner.

[0070] In the technical solution of the image forming device provided by the embodiment of the present invention, the magnetic induction element generates an induced current by relative displacement with the magnetic element, and the de-electrification device de-electrifies the photosensitive element through the induced current generated by the magnetic induction element. The de-electrification device can de-electrify the photosensitive element without the need for an additional power supply, thereby reducing the space occupied by the de-electrification structure. The de-electrification structure has a simple structure and adopts a passive design, and does not require external power supply. When the magnetic induction element and the magnetic element are relatively displaced, the magnetic induction element generates an induced current to drive the de-electrification device to de-electrify. Therefore, the de-electrification degree of the de-electrification device changes with the speed of the relative displacement of the magnetic induction element and the magnetic element, thereby achieving matching between the speed of the relative displacement of the magnetic induction element and the magnetic element and the de-electrification degree, effectively preventing the de-electrification structure from excessively or insufficiently de-electrifying the photosensitive element, and thereby achieving matching de-electrification between the de-electrification structure and the photosensitive element.

Figure 6 This is a schematic diagram of the working principle of the static dissipation structure in an embodiment of the present invention. Figure 7 The working principle diagram of the rectifier and filter circuit in the embodiment of the present invention is shown below. Figures 5 to 7 ,right Figure 1 and Figure 2 The de-energizing method of the de-energizing structure shown in FIG is described in detail. Figure 5 As shown, the de-electrical method includes:

[0072] Step 102: The magnetic induction component and the magnetic component are relatively displaced, so that the magnetic induction component generates an induced current.

[0073] like Figure 2 and Figure 6 As shown, the driving component 22 rotates to drive the photosensitive component 20 to rotate and the magnetic component 21 to rotate. As the magnetic component 21 rotates, the magnetic induction component 2 and the magnetic component 21 are relatively displaced, so that the magnetic induction component 2 generates an induced current.

[0074] Specifically, if Figure 2 、 Figure 3 and Figure 6 As shown, when the magnetic part 21 rotates, a changing magnetic field is generated, and the magnetic induction part 2 cuts the magnetic field to generate an induced electromotive force E, that is, the magnetic induction part 2 cuts the magnetic field to generate an induced current. In other words, the magnetic induction part 2 cuts the magnetic lines of force in the magnetic field to generate an induced current, wherein the induced current is an alternating current.

[0075] As an alternative, Figure 2 and Figure 6 As shown, the driving circuit 4 includes a rectifier and filter circuit, and the de-energizing device 1 is an LED. The driving circuit 4 performs rectification and filtering on the induced current to generate a power supply voltage VCC, wherein the power supply voltage is a DC power supply voltage. The driving circuit 4 provides power to the de-energizing device 1 through the power supply voltage VCC, thereby enabling the magnetic induction element 2 to output the induced current to the de-energizing device 1 through the driving circuit 4. Specifically, Figure 6 As shown, the driving circuit 4, the current limiting resistor R and the de-energizing device 1 are connected in series. The driving circuit 4 outputs the power supply voltage VCC and supplies power to the de-energizing device 1 through the current limiting resistor R, so that the magnetic induction element 2 outputs the induced current to the de-energizing device 1 through the driving circuit 4 to drive the de-energizing device 1 to emit light.

[0076] In addition, the driving circuit 4 may further include an amplifier circuit and / or a voltage stabilization circuit, which can amplify and stabilize the current.

[0077] like Figure 2 、 Figure 3 and Figure 7As shown, after one rotation of the photosensitive component 20, the number n of induced electromotive forces E generated by the magnetic induction elements 2 is a×b, where a is the number of magnetic induction elements 2 and b is the number of magnetic elements 21. The drive circuit 1 rectifies the a×b induced electromotive forces E generated by the magnetic induction elements 2 to produce 2a×b induced electromotive forces E. The drive circuit 4 then filters these 2a×b induced electromotive forces E to produce the supply voltage VCC. The greater the number of induced electromotive forces E per unit time, the more stable the output supply voltage VCC after filtering. The induced electromotive force E is determined by the change in magnetic flux per unit time of the magnetic induction elements 2, i.e., E = ΔQ / Δt, where ΔQ is the change in magnetic flux and is related to the magnetic pole strength of the magnetic elements 21 and the rotational speed of the photosensitive component 20. The change in magnetic flux ΔQ is proportional to the rotational speed of the photosensitive element 20. Therefore, the induced electromotive force E is proportional to the rotational speed of the photosensitive element 20. Specifically, the induced current is proportional to the rotational speed of the photosensitive element 20. The faster the rotational speed of the photosensitive element 20, the greater the induced electromotive force E (induced current), the stronger the intensity of the light emitted by the de-energizing device 1, and the higher the brightness of the emitted light. In other words, the brightness of the light emitted by the de-energizing device 1 is proportional to the rotational speed of the photosensitive element 20. For example, the faster the rotational speed of the photosensitive element 20, the higher the brightness of the light emitted by the de-energizing device 1, and the faster the residual charge on the photosensitive surface of the photosensitive element 20 is eliminated. Alternatively, as the rotational speed of the photosensitive element 20 slows (for example, when the image forming apparatus is in intermittent printing mode or silent printing mode), the brightness of the light emitted by the de-energizing device 1 decreases as the rotational speed of the photosensitive element 20 slows, and the speed of eliminating residual charge on the photosensitive surface of the photosensitive element 20 also decreases. Therefore, the brightness of the de-electrification device 1 changes with the rotation speed of the photosensitive component 20, making the brightness of the de-electrification device 1 controllable. This achieves a match between the rotation speed of the photosensitive component 20 and the degree of de-electrification, effectively preventing the de-electrification structure from over-electrifying the photosensitive component 20 or insufficiently de-electrifying the photosensitive component 20, thereby achieving matched de-electrification between the de-electrification structure and the photosensitive component.

[0078] Step 104: The static dissipation device receives the induced current and starts.

[0079] As an optional method, when the neutralization device 1 is an LED, the induced current is used to drive the neutralization device 1 to emit light, so as to start the neutralization device 1 .

[0080] Step 106: The charge-eliminating device eliminates the residual charge on the photosensitive surface of the photosensitive component.

[0081] like Figure 3As shown, the light emitted by the de-electrification device 1 is irradiated onto the photosensitive surface of the photosensitive component 20 to de-electrify the residual charge on the photosensitive surface of the photosensitive component 20. The light emitted by the de-electrification device 1 is irradiated onto the lens 302, which converges the light onto the light guide 301. The light guide 301 guides the light so that the light irradiates the photosensitive surface of the photosensitive component 20. The reflective film 303 can reflect excess light emitted by the light guide 301 back to the light guide 301, allowing the light guide 301 to also irradiate the excess light onto the photosensitive component 20. After the photosensitive surface of the photosensitive component 20 is irradiated with light, the residual charge is evenly guided away, thereby achieving de-electrification of the residual charge on the photosensitive surface of the photosensitive component 20.

[0082] In the technical solution of the de-charge method provided by the embodiment of the present invention, the magnetic induction component and the magnetic component are relatively displaced to cause the magnetic induction component to generate an induced current, the de-charge device receives the induced current and is started, and the de-charge device de-charges the residual charge on the photosensitive surface of the photosensitive component. The de-charge device can de-charge the photosensitive component without the need for an additional power supply, thereby reducing the space occupied by the de-charge structure, and the structure of the de-charge structure is simple, adopts a passive design, and does not require external power supply; when the magnetic induction component and the magnetic component are relatively displaced, the magnetic induction component generates an induced current to drive the de-charge device to de-charge, therefore, the de-charge degree of the de-charge device changes with the speed of the relative displacement of the magnetic induction component and the magnetic component, thereby achieving matching between the speed of the relative displacement of the magnetic induction component and the magnetic component and the de-charge degree, effectively preventing the de-charge structure from excessively de-charging or insufficiently de-charging the photosensitive component, and thereby achieving matching de-charge between the de-charge structure and the photosensitive component.

[0083] The embodiment of the present invention effectively prevents the excessive de-electrification of the photosensitive component by the de-electrification device, avoids the photosensitive component from suffering from light fatigue such as overcharging and over-discharging, thereby improving the life of the photosensitive component; the embodiment of the present invention effectively prevents insufficient de-electrification of the photosensitive component, avoids the phenomenon of ghosting in the printed image, thereby improving the quality of the printed image.

[0084] In the technical solution of the embodiment of the present invention, the induced current generated by the magnetic induction element is proportional to the rotational speed of the photosensitive component, and the light intensity of the de-electrification device is proportional to the rotational speed of the photosensitive component. Therefore, the light intensity of the de-electrification device matches the rotational speed of the photosensitive component, so that the dark decay curves of the de-electrification device and the photosensitive component can also be matched, so that the photosensitive surface of the photosensitive component can be effectively de-electrified, thereby improving the charging and discharging capacity of the photosensitive component, preventing the occurrence of ghosting and fatigue phenomena such as overcharging and over-discharging, and extending the life of the photosensitive component.

[0085] In the technical solution of the embodiment of the present invention, the photosensitive surface of the photosensitive component is de-charged through passive de-charge devices and light guides, which reduces the residual charge on the surface of the photosensitive component and reduces light fatigue, thereby avoiding the ghosting phenomenon that occurs during the printing process and improving the quality of the printed image.

[0086] Figure 8 A structural diagram of another consumables box provided by an embodiment of the present invention, such as Figure 8 As shown, in Figure 3 Based on the embodiment shown, the consumable box also includes a detection component 5, which is used to output a detection current corresponding to the induced current. The detection current increases as the rotation speed of the photosensitive component 20 increases. The detection current is used to determine whether the imaging component meets expectations.

[0087] The detection member 5 is electrically connected to the processing cartridge chip 6. The detection member 5 may include a photosensitive element, such as a photoresistor or a photodiode. The detection member 5 is electrically connected to the consumable cartridge chip 6 via wires or metal contacts. In this embodiment of the present invention, the consumable cartridge chip 6 is removably mounted on the consumable cartridge and is also electrically connected to the main control chip of the image forming device. It should be noted that the main control chip is not specifically shown in the figure.

[0088] In order to allow the light emitted by the de-electrification device 1 to illuminate the detection member 5, the detection member 5 can be located at the second end of the photosensitive component 20, wherein the second end is arranged opposite to the first end, and the de-electrification device 1 can illuminate the emitted light to the detection member 5 through the light guide 301.

[0089] As an optional solution, the light guide 301 includes a first light guide portion and a second light guide portion, the first light guide portion is arranged opposite to the photosensitive component 20, and the second light guide portion is arranged opposite to the detection element 5. Figure 8 As shown, the light guide 301 is divided into two parts by a dotted line, wherein one part is a first light guide part and the other part is a second light guide part. The second light guide part is a structure in which the first light guide part extends along the length direction of the photosensitive component 20. The first light guide part and the second light guide part can be integrally formed. The light emitted by the first light guide part can be irradiated onto the photosensitive component 20, and the light emitted by the second light guide part can be irradiated onto the detection component 5. When the light is irradiated onto the detection component 5, the optical properties of the detection component 5 are changed. The detection component 5 generates a detection current under the irradiation of light, and transmits the detection current to the consumable box chip 6. The light detection circuit of the consumable box chip 6 converts the detection current into an analog voltage, and outputs the analog voltage to the main control chip. Among them, the detection current is a photocurrent.

[0090] like Figure 3 and Figure 8 As shown, as an optional solution, the second end of the photosensitive component 20 can also be provided with a driving component to drive the photosensitive component 20 to rotate together with the driving component provided at the first end. The driving component provided at the second end can be the same as the driving component provided at the first end. The driving component provided at the second end is a gear. Figure 3 and Figure 8The driving component provided at the second end is not specifically drawn.

[0091] based on Figure 8 The consumable box in the embodiment of the present invention further includes:

[0092] Step 202: The neutralization device irradiates the emitted light onto the detection element.

[0093] like Figure 8 As shown, the de-electrification device 1 can irradiate the emitted light to the detection element 5 through the light guide 301. Specifically, when the photosensitive component 20 and the magnetic component 21 rotate, the de-electrification device 1 emits light and irradiates the emitted light to the lens 302. The lens 302 converges the light to the light guide 301. The light guide 301 guides the light so that the light emitted by the first light guide part of the light guide 301 is irradiated onto the photosensitive component 20 and the light emitted by the second light guide part of the light guide 301 is irradiated onto the detection element 5.

[0094] Step 204: The detection component generates a detection current under the irradiation of light and outputs the detection current to the consumable box chip.

[0095] Step 206 : The consumable box chip converts the detection current into an analog voltage and outputs the analog voltage to the main control chip, so that the main control chip can detect status information according to the analog voltage.

[0096] Since the brightness of the de-emission device 1 is proportional to the rotational speed of the photosensitive component 20, and the magnitude of the detection current generated by the detection component 5 is proportional to the brightness of the de-emission device 1, the magnitude of the detection current generated by the detection component 5 is proportional to the rotational speed of the photosensitive component 20. The greater the rotational speed of the photosensitive component 20, the greater the photocurrent generated by the detection component 5, and thus the greater the analog voltage converted from the detection current; alternatively, the smaller the rotational speed of the photosensitive component 20, the smaller the detection current generated by the detection component 5, and thus the smaller the analog voltage converted from the detection current. The main control chip detects different status information for different analog voltages, which may include first status information or second status information. Specifically, the main control chip can detect first status information corresponding to analog voltage A based on the larger analog voltage A; and / or the main control chip can detect second status information corresponding to analog voltage B based on the smaller analog voltage B. For example, when the photosensitive component 20 rotates from non-rotation to slow rotation, the analog voltage received by the main control chip will slowly rise from 0V to 5V, and the second state information can be detected based on the analog voltage; and / or, when the photosensitive component 20 rotates from slow rotation to fast rotation, the analog voltage received by the main control chip will slowly rise from 5V to 10V, and the first state information can be detected based on the analog voltage. Therefore, when the main control chip detects the first state information, it indicates that the detection current generated by the detection component 5 is large, and when the main control chip detects the second state information, it indicates that the detection current generated by the detection component 5 is small. However, as long as the main control chip can receive the analog voltage and then detect the first state information and / or the second state information based on the analog voltage, regardless of the size of the analog voltage, it can be determined whether the consumable box meets expectations.

[0097] In an embodiment of the present invention, by providing a detection component in the consumable box, the main control chip can detect status information based on the detection current generated by the detection component, and then determine based on the status information that the consumable box can be used and the consumable box and the image forming device are matched.

[0098] like Figure 9 As shown, in Figure 3 On the basis of the embodiment shown, the carrier 3 also includes a power recovery device 33, which is electrically connected to the magnetic induction component 2 and the de-electrification device 1 respectively. The magnetic induction component 2 transmits the induced current to the de-electrification device 1 through the power recovery device 33. The power recovery device 33 is used to store the induced current or prevent the induced current from being transmitted to the de-electrification device 1 when the photosensitive component 20 does not need to be de-electrified.

[0099] The extended portion of the carrier 3 may be a selective switch 32. The selective switch 32 is connected to the first end a of the power recovery device 33 so that the power recovery device 33 is electrically connected to the magnetic induction component 2. The selective switch 32 may be configured to charge the power recovery device 33 or prevent the induced current from being transmitted to the de-energizing device 1. At this time, the photosensitive component 20 does not need to be de-energized, and the power recovery device 33 stores the induced current or prevents the induced current from being transmitted to the de-energizing device 1. When the selective switch 32 is configured to charge the power recovery device 33, the power recovery device 33 may be a battery or other energy storage device. The selective switch 32 is connected to the second end b of the power recovery device 33 so that the power recovery device 33 is electrically connected to the de-energizing device 1. The selective switch 32 may be configured to directly power the de-energizing device 1. At this time, the magnetic induction component 2 may transmit the induced current to the de-energizing device 1 through the power recovery device 33.

[0100] During the imaging process, including charging, developing, and transferring, the photosensitive component 20 needs to rotate to form the developer image on the paper. However, at this time, the photosensitive component 20 does not require the de-energizing device 1. When the image formation control unit controls the drive component 22 to rotate, the magnetic component 21 generates a magnetic field as it rotates. The magnetic induction element 2 cuts the magnetic lines of force in the magnetic field to generate an induced current, and the drive circuit continues to generate a supply voltage. This embodiment provides a power recovery device 33 to recover the power supply voltage generated by the rotation of the photosensitive component 20 when the de-energizing device 1 is not required. This protects the photosensitive component 20 and prevents accidental de-energization, overexposure, or excessive de-energization of the photosensitive component 20. Furthermore, after collecting a certain amount of power, the power recovery device 33 can also provide a power source for the de-energizing device 1, saving energy and increasing the power supply for the de-energizing device 1. Therefore, through the embodiment of the present invention, when the photosensitive component 20 does not need to use the de-electrification device 1, the image formation control unit controls the selective switch to connect to the power recovery device 33, so as to recover the power of the power supply voltage generated by the driving circuit; when the photosensitive component 20 needs to use the de-electrification device 1 to perform a de-electrification operation, the image formation control unit controls the selective switch to connect to the de-electrification device 1 for direct power supply, thereby the de-electrification device 1 performs a matching de-electrification operation for the photosensitive component 20.
