In an image forming device, a developer containing device (such as an ink cartridge, a powder box, a powder cartridge, a toner cartridge, etc.) and an imaging component are usually included. Among them, the developer containing device can supply the developer (such as ink, toner, etc.) therein to the imaging component. The imaging component includes a photosensitive drum, a charging component, and a developing component. The charging component can make the surface of the photosensitive drum uniformly charged so that the uniformly charged surface of the photosensitive drum carries an electrostatic latent image, and the electrostatic latent image is developed by the developing component and the developer to form an image.

[0003] Specifically, a developer transmission channel is provided between the developer containing device and the imaging component, and a developer transmission component is provided in the developer transmission channel. When the developer in the imaging component is consumed, the developer containing device can supply the developer in the developer transmission channel to the developer transmission channel, and then the developer transmission component transmits the developer in the developer transmission channel to the imaging component, replenishing the developer for the imaging component to ensure the normal operation of the imaging component.

[0004] However, in actual applications, due to the lack of precise control over the developer supply, the amount of developer supplied to the imaging component is not fixed, and the developer is unevenly and unstably distributed in the imaging component, which in turn causes defects such as white spots and color spots in the image, and even causes polymers to appear in the developer of the imaging component.

[0120] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0121] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0122] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0123] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0124] See also Figure 1 , is a schematic diagram of a three-dimensional structure of an image forming device provided in an embodiment of the present application; see Figure 2 , is a structural block diagram of an image forming device provided in an embodiment of the present application. Figure 1 Combined with Figure 2 As shown, the image forming device 1000 includes a body 1100, and the body 1100 includes a frame (the outer shell of the body 1100) and a receiving chamber 1110. A developer receiving device 100 (such as an ink cartridge, a powder box, a powder cartridge, a toner cartridge, etc.) and an imaging component 310 are arranged in the receiving chamber 1110. The developer receiving device 100 is used to receive a developer (such as ink, toner, etc.), and the developer in the developer receiving device 100 can be supplied to the imaging component 310. The imaging component 310 includes a photosensitive drum, a charging component, a developing component, etc. The charging component can uniformly charge the surface of the photosensitive drum so that the uniformly charged surface of the photosensitive drum carries an electrostatic latent image, and the electrostatic latent image is developed by the developing component and the developer to form an image.

[0125] See also Figure 3 , is a schematic diagram of the matching relationship between a developer containing device and an imaging assembly provided in an embodiment of the present application; see Figure 4 , is a partial structural diagram of a developer containing device and an imaging assembly provided in an embodiment of the present application. Figure 3 Combined with Figure 4 As shown, a developer transfer channel 320 is provided between the developer containing device 100 and the imaging component 310, and a developer transfer component 330 (not shown in the figure) is provided in the developer transfer channel 320. When the developer in the imaging component 310 is consumed, the developer containing device 100 can supply the developer therein to the developer transfer channel 320, and then the developer transfer component 330 transfers the developer in the developer transfer channel 320 to the imaging component 310, so as to replenish the developer for the imaging component 310 and ensure the normal operation of the imaging component 310.

[0126] However, in actual applications, due to the lack of precise control over the developer supply, the amount of developer supplied to the imaging component 310 is not fixed, and the developer is unevenly and unstably distributed in the imaging component 310, which in turn causes defects such as white spots and color spots to appear in the image, and even causes the developer in the imaging component 310 to polymerize and generate polymers.

[0127] In view of the above problems, an embodiment of the present application provides a developer supply control device, which includes a developer transmission component, a remaining information feedback unit and a state detection unit. The remaining information feedback unit can send the remaining information of the developer in the imaging component to the image forming device, and the state detection unit can detect the working state of the developer transmission component and send the detected working state information to the image forming device. The image forming device determines whether to control the developer containing device to supply the developer to the developer transmission channel based on the remaining information and working state information of the developer, so as to achieve precise control of the developer supply amount, so that the developer can stably and evenly enter the imaging component, so as to improve the image quality of the image forming device and avoid the polymerization of the developer in the imaging component. The following is a detailed description in conjunction with the specific implementation method.

[0128] See also Figure 5 , is a structural block diagram of a developer supply control device provided in an embodiment of the present application. Figure 5 As shown, the developer supply control device 300 includes an imaging component 310, a developer transmission channel 320, and a developer transmission component 330. The developer transmission channel 320 is used to connect the developer containing device 100 and the imaging component 310, and the developer transmission component 330 is arranged in the developer transmission channel 320 (partially or entirely arranged in the developer transmission channel 320). The developer transmission component 330 can transmit the developer supplied by the developer containing device 100 to the developer transmission channel 320 to the imaging component 310.

[0129] like Figure 6-Figure 8 As shown, in the embodiment of the present application, the developer transmission assembly 330 includes a driving member 331 and a toggle member 332. The driving member 331 is used to receive the driving force of the image forming apparatus 1000, and the toggle member 332 is connected to the driving member 331. The toggle member 332 is used to rotate under the drive of the driving member 331 to toggle the developer in the developer transmission channel 320, so that the developer in the developer transmission channel 320 is transmitted to the imaging assembly 310.

[0130] Specifically, the driving member 331 includes a first driving gear 3312, and the first driving gear 3312 is used to mesh with other gears in the image forming device 1000 so as to receive the driving force provided by other gears in the image forming device 1000, so that the driving member 331 rotates. Exemplarily, the first driving gear 3312 can mesh with the gear in the imaging assembly 310. When the imaging assembly 310 is driven, the imaging assembly 310 drives the first driving gear 3312 to rotate, thereby rotating the driving member 331. Of course, those skilled in the art can also use other functional units in the image forming device 1000 to provide driving force for the driving member 331 according to actual needs, and the embodiment of the present application does not make specific restrictions on this. However, those skilled in the art should understand that in the image forming device 1000, the developer transmission assembly 330 is usually close to the imaging assembly 310. Therefore, providing driving force for the driving member 331 through the imaging assembly 310 can make the structure of the image forming device 1000 more compact.

[0131] In a possible implementation, the driving member 331 includes a tubular connecting portion 3311, and the tubular connecting portion 3311 is provided with a cavity. Correspondingly, the toggle member 332 is provided with an axial connecting portion 3321 matching the tubular connecting portion 3311, and the axial connecting portion 3321 is used to be installed in the cavity of the tubular connecting portion 3311, thereby achieving the connection between the driving member 331 and the toggle member 332.

[0132] Furthermore, a convex portion 33211 is provided on the shaft-shaped connecting portion 3321, and a concave portion (not shown in the figure) matching the convex portion 33211 is provided in the cavity of the tubular connecting portion 3311. When the shaft-shaped connecting portion 3321 is installed in the tubular connecting portion 3311, the convex portion 33211 on the shaft-shaped connecting portion 3321 is embedded in the concave portion in the cavity of the tubular connecting portion 3311. It can be understood that when the driving member 331 rotates, the driving member 331 can drive the toggle member 332 to rotate at the same speed through the matching relationship between the convex portion 33211 and the concave portion.

[0133] In a possible implementation, the shaft-shaped connecting part 3321 includes a plurality of protrusions 33211, which are arranged at intervals. Accordingly, a plurality of recesses matching the plurality of protrusions 33211 are arranged in the cavity of the tubular connecting part 3311, and the plurality of recesses are also arranged at intervals. When the shaft-shaped connecting part 3321 is installed in the tubular connecting part 3311, the plurality of protrusions 33211 on the shaft-shaped connecting part 3321 are embedded in the plurality of recesses in the cavity of the tubular connecting part 3311, so as to realize the connection between the driving member 331 and the toggle member 332. It is understandable that when the driving member 331 and the toggle member 332 are connected by a plurality of protrusions 33211 and a plurality of recesses, the connection strength and reliability between the driving member 331 and the toggle member 332 can be improved. Exemplarily, the number of the protrusions 33211 and the recesses can be 2, 3, 4, etc., and the embodiment of the present application does not specifically limit this.

[0134] Further, when there are multiple protrusions 33211 on the shaft-shaped connecting portion 3321, the multiple protrusions 33211 are centrally symmetrically arranged relative to the axis of the shaft-shaped connecting portion 3321. Correspondingly, the multiple recesses in the cavity of the tubular connecting portion 3311 are centrally symmetrically arranged relative to the axis of the tubular connecting portion 3311. Figure 8 In the implementation shown, there are four protrusions 33211 on the shaft-shaped connecting portion 3321, and the four protrusions 33211 are centrally symmetrically arranged relative to the axis of the shaft-shaped connecting portion 3321, so that the four protrusions 33211 are in a cross shape. In other words, the interval between any two adjacent protrusions 33211 is 90°. In the embodiment of the present application, the multiple protrusions 33211 and the multiple recesses are arranged in a centrally symmetrical manner, which can make the connection position of the driving member 331 and the toggle member 332 more uniformly stressed, thereby improving the service life of the developer supply control device 300.

[0135] In some possible implementations, the driving member 331 is detachably connected to the toggle member 332. This detachable connection can facilitate the maintenance of the developer supply control device 300 and the replacement of parts. Of course, those skilled in the art can also integrally form the driving member 331 and the toggle member 332 according to actual needs. It is understandable that when the driving member 331 and the toggle member 332 are integrally formed, the connecting member (for example, the axial connecting portion 3321, the tubular connecting portion 3311, the convex portion 33211, the concave portion, etc.) between the driving member 331 and the toggle member 332 can be replaced, and the embodiment of the present application does not limit this.

[0136] It should be pointed out that Figure 6-Figure 10The connection method between the driving member 331 and the toggle member 332 shown is only an exemplary description of the embodiment of the present application and should not be used as a limitation on the protection scope of the present application. For example, in some possible implementations, an axial connection portion 3321 can be provided on the driving member 331, and a tubular connection portion 3311 can be provided on the toggle member 332 to achieve the connection between the driving member 331 and the toggle member 332. Alternatively, the axial connection portion 3321 and the tubular connection portion 3311 are set to an interference fit, thereby replacing the convex portion 33211 on the axial connection portion 3321 and the concave portion in the cavity of the tubular connection portion 3311, etc.

[0137] Please continue reading Figure 6-Figure 8 In the embodiment of the present application, the toggle member 332 also includes a toggle blade portion 3322 and a spacer portion 3323. The toggle blade portion 3322 is connected to the shaft-shaped connecting portion 3321, and is used to rotate under the drive of the driving member 331. When the toggle blade portion 3322 rotates, the developer in the developer transmission channel 320 can be toggled, so that the developer in the developer transmission channel 320 is transmitted to the imaging assembly 310. In the embodiment of the present application, there are two toggle blade portions 3322, and the two toggle blade portions 3322 are centrally symmetrically arranged relative to the axis of the shaft-shaped connecting portion 3321, so that the two toggle blade portions 3322 are in a straight line shape. In other words, the two toggle blade portions 3322 are spaced 180° apart. Of course, those skilled in the art can set more or fewer number of toggle blades 3322 on the toggle member 332 according to actual needs, for example, the number of toggle blades 3322 is 1, 3, 4, 5, etc., and the embodiment of the present application does not impose specific restrictions on this. It should be supplemented that when multiple toggle blades 3322 are set on the toggle member 332, the multiple toggle blades 3322 are centrally symmetrically arranged relative to the axis of the axial connection portion 3321, so that the toggle member 332 can more evenly toggle the developer in the developer transmission channel 320 into the imaging component 310, so that the developer is more evenly distributed in the imaging component 310.

[0138] The spacer 3323 is disposed between the moving blade portion 3322 and the shaft-shaped connecting portion 3321, and is used to prevent the developer in the developer transmission channel 320 from reaching the shaft-shaped connecting portion 3321, thereby preventing the developer from leaking. Figure 6-Figure 8 In the implementation shown, the cross section of the spacer 3323 is circular. Of course, those skilled in the art may also set the spacer 3323 to other shapes according to actual needs, and the embodiment of the present application does not specifically limit this.

[0139] Please continue reading Figure 5In an embodiment of the present application, the developer supply control device 300 also includes a remaining information feedback unit 340, which is used to send the remaining information of the developer in the imaging component 310 to the image forming device 1000, and the remaining information of the developer is used to determine whether the imaging component 310 needs to be supplied with developer.

[0140] In some possible implementations, the remaining information feedback unit 340 includes a remaining information detection unit for detecting the remaining information of the developer in the imaging component 310. For example, the remaining information detection unit may be a developer carrier ratio sensor 341. For example, the developer carrier ratio sensor 341 is a toner concentration sensor (TC sensor). The toner concentration sensor (TC sensor) is a type of magnetic flux sensor. The toner concentration sensor (TC sensor) is provided with a power line, which is electrically connected to a data board of the image forming device. The data board has a digital-to-analog converter, which can be understood as a digital-to-analog converter that converts analog information into a digital signal and transmits the digital information to a processor (SOC) of the image forming device. Specifically, the toner concentration sensor (TC sensor) is provided on the imaging component 310. When the imaging component 310 is in working state, the toner concentration sensor (TC sensor) starts the detection work. The toner concentration sensor (TC sensor) The sensor will collect analog voltage information, which is transmitted to the data board through the power line. The digital-to-analog converter of the data board converts the analog voltage information into a digital voltage signal, which is then transmitted to the processor (SOC) of the image forming device. Fig. 9 As shown, the developer carrier ratio sensor 341 can be based on the developer-to-carrier ratio of the imaging component 310 (the developer-to-carrier ratio can reflect whether the imaging component 310 needs to be supplied with developer). Specifically, the developer-to-carrier ratio here can be understood as the gram weight ratio of the developer to the carrier. For example, when the ratio is less than or equal to 7%, it means that the imaging component 310 needs to be supplied with developer. Further, the remaining amount information of the developer in the imaging component 310 is generated (in other parts of this document, the remaining amount information of the developer may also be referred to as a "remaining amount information detection signal", and the remaining amount information detection signal here is an analog voltage value), such as Fig.16As shown, after obtaining the remaining information detection signal, the image forming apparatus 1000 can analyze the remaining information detection signal, and then determine whether the imaging component 310 needs to supply developer according to the analysis result. For example, the voltage value of the remaining information detection signal is compared with the preset voltage threshold. If the voltage value of the remaining information detection signal is higher than or equal to the preset voltage threshold, it is determined that the imaging component 310 needs to supply developer; if the voltage value of the remaining information detection signal is lower than the preset voltage threshold, it is determined that the imaging component 310 does not need to supply developer. Alternatively, if the voltage value of the remaining information detection signal is higher than the preset voltage threshold, it is determined that the imaging component 310 does not need to supply developer; if the voltage value of the remaining information detection signal is lower than or equal to the preset voltage threshold, it is determined that the imaging component 310 needs to supply developer. In some possible implementations, after the image forming device prints an image, the processor (SOC) of the image forming device obtains the number of light spots emitted by the LSU. After obtaining the number of light spots, the processor (SOC) compares it with the light spot powder consumption value table stored in the storage unit (chip of the SOC) of the image forming device. The processor (SOC) further uses the number of light spots to look up the table to obtain the developer consumption of the imaging component, and accumulates the obtained developer consumption to the consumable chip of the imaging component. The consumable chip determines the developer remaining amount of the imaging component based on the obtained developer consumption information, that is, the developer remaining amount information in the imaging component 310 can be obtained by communicating with the consumable chip of the imaging component. The embodiment of the present application does not limit the method for determining the developer remaining amount information in the imaging component 310.

[0141] In some possible implementations, the remaining information feedback unit may also be a transmission component for transmitting the developer remaining information in the imaging component 310 to the image forming device 1000. The transmission component may include a connecting component for establishing an electrical connection with the image forming device 1000, and may also include a conductor for transmitting the developer remaining information in the imaging component 310. The conductor may be a wire, etc. For example, the transmission component may be a chip contact for connecting to the image forming device 1000, or one end of the wire may be electrically connected to the transmission component, and the other end of the wire is provided with a plug-in terminal, which is electrically connected to the interface of the image forming device 1000 in a plug-in manner, so as to realize the transmission of the developer remaining information in the imaging component 310 to the image forming device 1000.

[0142] In some other implementations, the surplus information feedback unit may include the aforementioned surplus information detection unit and the aforementioned transmission component. The embodiment of the present application does not limit the specific form of the surplus information feedback unit.

[0143] It is understandable that in the process of supplying developer to the imaging component 310, if the working state of the developer transport component 330 is unstable (for example, the rotation speed of the developer transport component 330 is unstable), the developer cannot be evenly supplied to the imaging component 310, and the developer is unevenly and unstably distributed in the imaging component 310, thereby causing defects such as white spots and color spots to appear in the image formed, and even causing polymers to appear in the developer of the imaging component 310. Therefore, in the present application, it is also necessary to detect the working state of the developer transport component 330 to determine whether the working state of the developer transport component 330 is stable.

[0144] Please continue reading Figure 5 In the embodiment of the present application, the developer supply control device 300 further includes a state detection unit 350, which is used to detect the working state of the developer transmission component 330 and send the detected working state information (in other parts of this document, the working state information of the developer transmission component 330 may also be referred to as "working state information detection signal") to the image forming device 1000. The image forming device 1000 determines whether to control the developer containing device 100 to supply the developer to the developer transmission channel 320 based on the remaining developer information in the imaging component and the working state information of the developer transmission component. Specifically, when the remaining information feedback unit detects the remaining developer in the imaging component 310 and transmits the remaining developer information in the imaging component 310 to the image forming device 1000, the image forming device 1000 determines whether to turn on the status detection unit 350 based on the remaining developer information of the imaging component 310. After the status detection unit 350 starts the detection work, the status detection unit 350 is used to detect the working state of the developer transmission component 330. When it is determined that the working state of the developer transmission component 330 is as expected, the developer containing device 100 is controlled to supply the developer to the developer transmission channel 320 of the developer supply control device 300, and the developer transmission component 330 is controlled to work so as to transmit the developer in the developer transmission channel 320 to the imaging component 310.

[0145] In a possible implementation, the state detection unit includes a state detection unit 350 and a photoelectric sensor B (such as Figure 8As shown in the figure, the state detection unit includes a reflective portion 351, which is arranged on the developer transmission assembly 330 and is used to reflect the light signal of the external light source to the image forming device 1000. In addition, a non-reflective area is also provided on the developer transmission assembly 330 (usually, all areas except the area where the reflective portion 351 is located are non-reflective areas). When the developer transmission assembly 330 rotates, the light signal of the external light source is alternately irradiated on the reflective portion 351 and the non-reflective area. It can be understood that when the light signal of the external light source is irradiated on the reflective portion 351, the reflective portion 351 can reflect the light signal to the outside; when the light signal of the external light source is irradiated on the non-reflective area, the non-reflective area cannot reflect the light signal to the outside.

[0146] Furthermore, the image forming apparatus 1000 further includes a photoelectric sensor 410, such as Fig.17 As shown, a photosensitive area 411 is provided on the photoelectric sensor 410, and the photoelectric sensor 410 can output a corresponding electrical signal according to the light intensity received by the photosensitive area 411. In the embodiment of the present application, when the light signal of the external light source is irradiated on the reflective portion 351, the reflective portion 351 can reflect the light signal to the photosensitive area 411 of the photoelectric sensor 410, so that the photosensitive area 411 obtains a strong light intensity, and then outputs a first level signal; when the light signal of the external light source is irradiated on the non-reflective area, the photosensitive area 411 obtains a weak light intensity (the non-reflective area may have a weak reflective ability, or there is ambient light that causes the photosensitive area 411 to obtain a weak light intensity), and then outputs a second level signal. That is, when the developer transport assembly 330 rotates, the light signal of the external light source is alternately irradiated on the reflective portion 351 and the non-reflective area, thereby obtaining an alternating first level signal and a second level signal, which is the working state information detection signal described above, or when the light signal of the external light source is irradiated on the reflective portion 351, the reflective portion 351 can reflect the light signal to the photosensitive area 411 of the photoelectric sensor 410, so that the photosensitive area 411 obtains a stronger light intensity, thereby outputting a second level signal; when the light signal of the external light source is irradiated on the non-reflective area, the photosensitive area 411 obtains a weaker light intensity, thereby outputting a first level signal. It should be supplemented that the external light source involved in the embodiment of the present application can be a part of the photoelectric sensor 410, or an independent light source outside the photoelectric sensor 410, and the embodiment of the present application does not impose specific restrictions on this.

[0147] See also Fig.18 , is a waveform diagram of a working status information detection signal provided by an embodiment of the present application. Fig.18As shown, the working state information detection signal includes a first level signal and a second level signal that change alternately, wherein the first level signal is a high level and the second level signal is a low level. It can be understood that the first level signal and the second level signal that change alternately can reflect the working state of the developer transmission component 330. It can be understood that the working state of the developer transmission component 330 is the rotation stability of the developer transmission component 330, that is, whether the time for the developer transmission component 330 to rotate one circle is fixed. If the time for the developer transmission component 330 to rotate one circle is fixed, the working state of the developer transmission component 330 is stable. Further, the image forming device 1000 can parse the working state information detection signal, obtain the parameters such as the period, high level duration, low level duration, high level frequency and / or low level frequency corresponding to the working state information detection signal, and judge whether the working state of the developer transmission component 330 meets expectations based on the above parameters.

[0148] Those skilled in the art should understand that as long as the "first level signal" and the "second level signal" can be distinguished, the working state of the developer conveying assembly 330 can be determined by parsing the working state information detection signal. Therefore, in some possible implementations, the first level signal can be set to a low level and the second level signal can be set to a high level; or the first level signal and the second level signal can be set to high levels at the same time, and there is a difference in the voltages corresponding to the first level signal and the second level signal, which is not specifically limited in the present embodiment.

[0149] In a possible implementation, the reflective portion 351 can be disposed on the toggle member 332 of the developer transmission assembly 330, and reflect the light signal of the external light source to the image forming device 1000 as the toggle member 332 rotates. It can be understood that, according to the setting position of the reflective portion 351 on the toggle member 332, the angle at which the reflective portion 351 receives the light signal of the external light source can be determined, so that when the toggle member 332 rotates to the angle, the reflective portion 351 reflects the light signal of the external light source. In addition, when the reflective portion 351 is disposed on the toggle member 332, the toggle member 332 includes a first non-reflective area, and when the driving member 331 drives the toggle member 332 to rotate, the light signal of the external light source alternately irradiates the reflective portion 351 and the first non-reflective area, thereby generating an alternating first level signal and a second level signal. The specific contents of the embodiments of the present application can be found in the above description, and for the sake of brevity, they will not be repeated here.

[0150] Similarly, the reflective portion 351 can also be arranged on the driving member 331 of the developer transmission assembly 330. For example, the driving member 331 is made of a reflective material, and the reflective portion 351 and the driving member 331 are integrally formed. If the driving member 331 is made of a non-reflective material, the reflective portion 351 is adhered to the driving member 331 by adhesive, and reflects the light signal of the external light source to the image forming device 1000 as the driving member 331 rotates. It can be understood that according to the setting position of the reflective portion 351 on the driving member 331, the angle at which the reflective portion 351 receives the light signal of the external light source can be determined, so that when the driving member 331 rotates to the angle, the reflective portion 351 reflects the light signal of the external light source. In addition, when the reflective portion 351 is arranged on the driving member 331, the driving member 331 includes a second non-reflective area. When the driving member 331 rotates, the light signal of the external light source is alternately irradiated to the reflective portion 351 and the second non-reflective area, thereby generating an alternating first level signal and a second level signal. For the specific contents of the embodiments of the present application, please refer to the above description. For the sake of brevity, they will not be repeated here.

[0151] In some possible implementations, such as Figure 10 to Figure 11As shown, the state detection unit includes a reflecting portion 351 and a photoelectric sensor B. An adhesive area 3311a is provided on the tubular connecting portion 3311 of the driving member 331. The reflecting portion 351 is adhered to the adhesive area 3311a of the tubular connecting portion 3311 of the driving member 331 by adhesive. Along the axial direction of the driving member 331, the reflecting portion 351 is parallel to the end surface 3322a of the moving blade portion 3322, and reflects the light signal of the external light source to the image forming device 1000 as the driving member 331 rotates. According to the setting position of the reflective portion 351 on the driving member 331, the angle at which the reflective portion 351 receives the light signal of the external light source can be determined, so that when the driving member 331 rotates to this angle, preferably, the photoelectric sensor B includes a light source, which has the same function as the external light source described above, and the light source emits light A. During the process of rotating the blade portion 3322 by 0°-90°, the reflective portion 351 reflects the light A of the light source B, and the photoelectric sensor receives the light A' reflected by the reflective portion 351, generates a light signal, and converts it into a level signal (or the photoelectric sensor receives the light A' reflected by the reflective portion 351, and generates a level signal). The driving member 331 includes a second non-reflective area. When the driving member 331 rotates, the light of the light source alternately irradiates the reflective portion 351 and the second non-reflective area, thereby generating an alternating first level signal and a second level signal, and the alternating first level signal and the second level signal can reflect the working state of the developer transmission assembly 330. Further described, the status detection unit detects whether the working status of the developer transmitting component is stable. If the working status of the developer transmitting component detected by the status detection unit is stable, the image forming device 1000 indicates that the developer in the developer containing device 100 can be supplied to the developer transmitting channel 320. If the working status of the developer transmitting component detected by the status detection unit is unstable, the image forming device 1000 does not indicate that the developer in the developer containing device 100 can be supplied to the developer transmitting channel 320.

[0152] In some possible implementations, the first level signal is a low level and the second level signal is a high level, or the first level signal is a high level and the second level signal is a low level, or both the first level signal and the second level signal are high levels, but the first level signal is different from the second level signal. Preferably, both the first level signal and the second level signal are high levels, for example, the level value of the first level signal is 0-2500mv, and the level value of the second level signal is 3000±200mv.

[0153] In some possible implementations, when the reflective portion 351 is disposed on the driving member 331, the reflective portion 351 is disposed on the driving member 331 at a position outside the developer transmission channel 320. Since the external light source is usually located outside the developer transmission channel 320, arranging the reflective portion 351 outside the developer transmission channel 320 can facilitate the external light source to irradiate the reflective portion 351. In addition, arranging the reflective portion 351 outside the developer transmission channel 320 can also prevent the developer in the developer transmission channel 320 from blocking the reflective portion 351, thereby improving the reliability of the developer supply control device 300. Similarly, when the reflective portion 351 is disposed on the toggle member 332, the reflective portion 351 is disposed on the toggle member 332 at a position outside the developer transmission channel 320, so that the external light source can irradiate the reflective portion 351 and improve the reliability of the developer supply control device 300, which will not be described in detail here.

[0154] In some possible implementations, due to the special requirements of certain application scenarios, it may be necessary to set the reflective portion 351 in the developer transmission channel 320. At this time, in order to allow the external light source to illuminate the reflective portion 351, a light-through port (not shown in the figure) may be opened on the outer wall of the developer transmission channel 320, and the light signal of the external light source is irradiated into the developer transmission channel 320 through the light-through port. In addition, in the axial direction of the developer transmission channel 320, the position of the reflective portion 351 on the developer transmission assembly 330 is opposite to the light-through port, so as to ensure that the reflective portion 351 can receive the light signal emitted by the external light source during the rotation of the developer transmission assembly 330. It should be supplemented that when the reflective portion 351 is set in the developer transmission channel 320, the light source can also be set in the developer transmission channel 320 at the same time. It can be understood that at this time, it is not necessary to open a light-through port on the outer wall of the developer transmission channel 320.

[0155] Please continue reading Figure 6-Figure 8In the embodiment of the present application, the reflective portion 351 is disposed on the shaft-shaped connecting portion 3321 of the toggle member 332. When the shaft-shaped connecting portion 3321 of the toggle member 332 is made of a reflective material, the reflective portion 351 and the shaft-shaped connecting portion 3321 are formed integrally, or when the shaft-shaped connecting portion 3321 of the toggle member 332 is made of a non-reflective material, the reflective portion 351 is adhered to the shaft-shaped connecting portion 3321 by adhesive. It can be understood that when the shaft-shaped connecting portion 3321 is installed in the cavity of the tubular connecting portion 3311, the tubular connecting portion 3311 will cover the shaft-shaped connecting portion 3321. In this case, in order to allow the external light source to still illuminate the reflective portion 351, the embodiment of the present application opens a light-transmitting window 33111 on the tubular connecting portion 3311, and when the shaft-shaped connecting portion 3321 is installed in the cavity of the tubular connecting portion 3311, the light-transmitting window 33111 at least partially overlaps with the reflective portion 351. It can be understood that according to this arrangement, the reflective portion 351 can receive the light signal emitted by the external light source during the rotation of the toggle member 332. Preferably, the light-transmitting window 33111 completely overlaps with the reflective portion 351 to increase the light intensity of the light signal.

[0156] Further, in a possible implementation, the reflective portion 351 is disposed on the convex portion 33211 of the axial connection portion 3321, and preferably, the reflective portion 351 and the toggling blade portion 3322 are disposed on a straight line. The concave portion in the cavity of the tubular connection portion 3311 is disposed correspondingly to the light-transmitting window 33111. Since when the axial connection portion 3321 is installed in the cavity of the tubular connection portion 3311, the convex portion 33211 of the axial connection portion 3321 matches the concave portion in the cavity of the tubular connection portion 3311, therefore, by disposing the light-transmitting window 33111 at a position corresponding to the concave portion in the cavity, it can be ensured that when the axial connection portion 3321 is installed in the cavity of the tubular connection portion 3311, the light-transmitting window 33111 overlaps with the reflective portion 351.

[0157] Further, in another possible implementation, a plurality of reflective portions 351 are arranged on a plurality of convex portions 33211 of the axial connection portion 3321, and one, two, or more light-transmitting windows 33111 are provided on the tubular connection portion 3311. The area of ​​the light-transmitting windows 33111 can be adjusted accordingly according to the number of light-transmitting windows 33111 provided, and the concave portion in the cavity of the tubular connection portion 3311 is provided correspondingly to the light-transmitting windows 33111. Since when the axial connection portion 3321 is installed in the cavity of the tubular connection portion 3311, the convex portion 33211 of the axial connection portion 3321 matches the concave portion in the cavity of the tubular connection portion 3311, therefore, by providing the light-transmitting windows 33111 at positions corresponding to the concave portions in the cavity, it can be ensured that when the axial connection portion 3321 is installed in the cavity of the tubular connection portion 3311, the light-transmitting windows 33111 overlap with the reflective portions 351.

[0158] Furthermore, when two light-transmitting windows 33111 are provided on the tubular connecting portion 3311 , the two light-transmitting windows 33111 are distributed and arranged at intervals of 180° along the circumferential direction.

[0159] Of course, those skilled in the art may also set the reflective portion 351 at other positions of the toggle member 332, or set the reflective portion 351 at other positions of the axial connection portion 3321 of the toggle member 332, according to actual needs, and the embodiment of the present application does not impose specific restrictions on this. In another embodiment, the embodiment of the present application provides an adapter 352, and the adapter 352 is detachably mounted on the developer supply control device 300. Furthermore, the developer supply control device 300 is provided with a mounting area 3311a, and the mounting area 3311a is used to mount the adapter 352. In this embodiment, the adapter 352 is a reflective sheet, and the reflective sheet has a mounting surface 3521 and a reflective surface 3522. When the adapter 352 is mounted on the developer control device 300, the mounting surface 3521 is mounted on the developer transmission assembly 330. The developer transmission component 330 is at least partially arranged in the developer transmission channel 320, and the developer transmission channel 320 connects the developer containing device 100 and the imaging component 310. The reflective surface 3522 is used to detect the working status of the developer transmission component 330.

[0188] Corresponding to the above-mentioned embodiment, the embodiment of the present application further provides a developer supply control method.

[0189] See also Fig.24 , is a flow chart of a developer supply control method provided in an embodiment of the present application. The method can be applied to an image forming device, on which a developer containing device and the developer supply control device described in the above embodiment are installed.

[0190] Step S1801: in response to an image forming operation triggered by a user, controlling the first driving unit to drive the imaging assembly to rotate;

[0191] Step S1802: receiving the developer remaining amount information of the imaging component sent by the developer supply control device;

[0192] Step S1803: judging whether the imaging component needs to be supplied with developer according to the remaining amount information of the developer of the imaging component;

[0193] Step S1804: receiving the working status information of the developer conveying assembly sent by the developer supply control device;

[0194] Step S1805: judging whether the working state of the developer conveying assembly meets expectations according to the working state information of the developer conveying assembly;

Further, based on the working status information of the developer transmission component, it is determined whether the working status of the developer transmission component is stable. When the working status of the developer transmission component is unstable, it is determined that the working status of the developer transmission component does not meet expectations.

[0199] In a possible implementation, if it is determined that the working state of the developer conveying assembly does not meet expectations, a first error prompt message is output to prompt the user to check the image forming apparatus.

[0204] Step S1902: in response to a power-on operation triggered by a user, the first driving unit drives the imaging assembly to rotate;

[0205] Step S1903: judging whether the working state of the developer transmission component is stable according to the working state information of the developer transmission component; when the working state of the developer transmission component is unstable, determining that the working state of the developer transmission component is not as expected.

[0206] In one possible implementation, if it is determined that the working state of the developer conveying component is as expected, the developer supply ready state is entered so that the image forming device performs the image forming operation based on the user's trigger; if it is determined that the working state of the developer conveying component is not as expected, a second error prompt message is output to prompt the user to check the image forming device.
