Description

[0001] This application claims the priority of the prior application with application number 202322497125.7 and invention name “Developer Box” filed by the applicant with the China Patent Office on September 13, 2023. All contents of the prior application are cross-referenced in this application. Technical Field

[0002] The invention relates to the field of electronic photographic imaging, and in particular to a developing box detachably installed in an imaging device. Background Art

[0003] A developer cartridge is a toner container that can be detachably installed in an imaging device. Usually, there is a one-to-one correspondence between the developer cartridge and the imaging device to which it is applicable. For this purpose, a detection device is provided in the developer cartridge. At the same time, a detection device that can be matched with the detected device is provided in the imaging device. Through the interaction between the detected device and the detection device, parameter information such as the model, service life, and whether it is a new developer cartridge of the developer cartridge can be determined by the imaging device.

[0004] There is a developing box having a driving force receiving member and a detection device respectively disposed at both ends in the longitudinal direction. Figure 1A It is a simplified schematic diagram of a detection device in an imaging device suitable for an existing developer cartridge, wherein the detection device includes a switch device 125 and an electrical contact 121, the switch device 125 has a first contact end 123 and a second contact end 126 located at both ends thereof and an abutted end 127 located between the two contact ends, the first contact end 123 is used to be electrically connected to a power source of the imaging device, and before the developer cartridge is installed in the imaging device, the switch device 125 is electrically disconnected from the electrical contact 121.

[0005] Figure 1B It is a side view of the interaction between the detected device and the detection device when viewed along the longitudinal direction of the developing box after the existing developing box is installed in the imaging device; Figure 1C It is a side view of the existing developing box after it is installed in the imaging device, observed along the longitudinal direction of the developing box, and the detected device and the detecting device do not interact with each other.

[0006] like Figure 1BAs shown, when the developer box is installed in the imaging device, the abutted end 127 of the switch device 125 is electrically connected to the electrode 88 in the developer box, and at the same time, the second contact end 126 is electrically connected to the electrical contact 121. At this time, the voltage detection unit in the imaging device can detect the voltage on the developer box, and the CPU of the imaging device recognizes that the developer box is installed, starts preheating, and transmits the driving force to the driving force receiving member, and the driving force receiving member then transmits the driving force to the shift block 52 set on the same side as the electrode 88. During the rotation of the shift block 52, when the shift block 52 pushes the switch device 125, the switch device 125 is disconnected from the electrode 88, and at the same time, the switch device 125 is also disconnected from the electrical contact 121. At this time, the voltage detection unit in the imaging device cannot detect the voltage on the developer box.

[0007] When the slider 52 moves away from the switch device 125, the switch device 125 returns to the position of being in electrical contact with the electrode 88 again. Meanwhile, the switch device 125 is in electrical contact with the electrical contact 121 again, and the voltage detection unit detects the voltage on the developer box again.

[0008] The imaging device determines the parameter information of the developing box by counting the number of times the voltage detection unit detects the voltage. However, since the switch device 125 has been fixedly set at a predetermined position of the imaging device, as mentioned above, the driving force for driving the shift block 52 needs to be transmitted from a driving force receiving member that is not set on the same side as the shift block 52. This method not only requires a driving force transmission mechanism to be set in the developing box, thereby complicating the structure of the developing box, but also is not conducive to the miniaturization of the developing box and reduces the freedom of design of the position of the shift block 52. Summary of the invention

[0009] To this end, the present invention provides a developer box, which adopts the following technical solution to achieve at least one of simplifying the structure of the developer box and improving the freedom of design of the shift block.

[0044] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] [Structure of the developer cartridge]

[0046] The developing box 100 can be detachably mounted to the imaging device, and includes a shell 1 and a rotating member rotatably disposed in the shell 1, wherein the shell 1 contains carbon powder required for the developing box to develop, and the rotating member can rotate around a rotation axis extending in a first direction.

[0047] Generally, a stirring frame for stirring toner and a developing roller 11 for carrying toner are provided in the developing box 100. The stirring frame is used to stir the toner contained in the shell. The developing roller 11 is used to carry the toner and supply the toner to the photosensitive drum on which the electrostatic latent image is formed. The photosensitive drum can be provided in the developing box 100 or outside the developing box 100. When the developing box 100 is developed in the imaging device, the developing roller 11 and the photosensitive drum are arranged opposite to each other and are close to each other. The rotation axis of the developing roller 11 is L1. In some embodiments, the developing box 100 further includes a powder feeding roller 16 (such as a powder feeding roller 16) rotatably provided in the shell 1. Figure 5A and Figure 5B As shown), the powder feeding roller 16 is in contact with the developing roller 11 and is used to transport the carbon powder toward the developing roller 11. Therefore, the developing roller 11, the powder feeding roller 16 and the stirring frame (not shown) can be respectively regarded as a kind of rotating part.

[0048] Furthermore, the developing box 100 also includes a driving force receiving member 13 for receiving driving force from the imaging device and an end cover 12 for allowing the driving force receiving member 13 to be exposed, and the driving force receiving member 13 transmits the received driving force to each rotating member through the driving force transmission assembly 3 described below. In a general structure, along the first direction, the driving force receiving member 13 is arranged at one end of the developing box 100 / shell 1. For ease of description, the end of the developing box 100 where the driving force receiving member 13 is arranged is the driving end F, and the end opposite to the driving end F is the non-driving end NF. Along the first direction, the driving end F and the non-driving end NF are respectively located at the two ends of the shell 1; in some embodiments, the non-driving end NF is also used to receive power from the imaging device, and therefore, the non-driving end NF is also called a conductive end.

[0049] In some embodiments, the developer box 100 also includes a chip assembly (not shown) for establishing a communication connection with an imaging device and a chip rack 15 for carrying the chip assembly. Preferably, the chip rack 15 is movably connected to the end cover 12 or the housing 1, thereby reducing the risk of contact failure between the chip assembly and the contact pins in the imaging device due to shaking of the developer box 100.

[0050] [Device under test]

[0051] Embodiment 1

[0052] The developing box 100 involved in this embodiment also includes a detected device 2, and a detecting device PE is provided in the imaging device. The detecting device PE detects the voltage value of the detecting position in the developing box 100 (the contact position between the developing box 100 / the detected device 2 and the detecting device PE), and the parameter information of the developing box 100 (including but not limited to the model of the developing box 100, the service life, whether it is a new developing box, etc.) can be judged by the imaging device.

[0053] See also Fig. 7A and Figure 7B The detection device PE in the imaging device includes a switch device 125, a CPU, a voltage detection unit, a power supply and an electrical contact 121, wherein the switch device 125 includes a first contact end 123 and a second contact end 126 and an abutted end 127 located between the first contact end 123 and the second contact end 126, the power supply is used to supply voltage to the developing box 100, and generally, the power of the power supply can be either an external power of the imaging device or a power supplied by a battery, etc.; the voltage detection unit is used to detect the voltage value of the detection position, and the CPU is used to compare the voltage value detected by the voltage detection unit with a preset voltage threshold, and according to the comparison, As a result, parameter information of the developing box 100 is obtained. For example, when the electrical connection of the detected device 2 is in a disconnected state, the voltage value detected by the voltage detection unit exceeds the threshold value, and the imaging device obtains a high voltage signal. Conversely, when the electrical connection of the detected device 2 is in a connected state, the voltage value detected by the voltage detection unit does not exceed the threshold value, and the imaging device obtains a low voltage signal. In practice, except for the abutted end 127, other components of the detection device PE are housed in the main component of the imaging device, which is shown in a dotted box in the figure. Therefore, the detection position is the position where the developing box 100 / the detected device 2 contacts the abutted end 127.

[0054] As described in the background art, before the developing cartridge 100 is installed in the imaging device, the electrical connection inside the detection device PE is disconnected. Figure 6As shown, the first contact end 123 is connected to the power source and the abutted end 127 at the same time, but the second contact end 126 is not in contact with the electrical contact 121. When the developing box 100 is installed on the imaging device, through the interaction between the detected device 2 and the detection device PE, the detected device 2 pushes the abutted end 127 to make the second contact end 126 contact with the electrical contact 121, and the electrical connection inside the detection device PE is changed from a disconnected state to a connected state. Before the developing box 100 is taken out of the imaging device, the detected device 2 and the abutted end 127 are always in contact, and the detection device PE is also always in a connected state; accordingly, the imaging device can detect the developing box 100. Specifically, the imaging device can determine the various parameter information of the developing box 100 according to the number of connections and / or disconnections of the electrical connection of the detected device 2 detected within a predetermined time, or, the imaging device can determine the various parameter information of the developing box 100 according to the number of high voltage signals and / or low voltage signals obtained within a predetermined time.

[0055] In an practicable manner, the moment when the detected device 2 pushes the abutted end 127 can occur during the installation process of the developing box 100 toward the predetermined position of the imaging device, or it can occur after the developing box 100 is installed to the predetermined position of the imaging device, and the detected device 2 is triggered by the trigger member, so that the detected device 2 abuts against the abutted end 127. In the latter manner, the installation resistance of the developing box 100 can be reduced, and the installation process will be smoother.

[0056] In an practicable manner, after the detection device 2 abuts against the abutted end 127, the abutted end 127 and the component of the detection device 2 used to abut against the abutted end 127 can remain stationary relative to the shell of the developer box 100, or can be set to be movable according to design requirements.

[0057] It can be understood that when the electrical connection of the detected device 2 is in a connected state, the voltage value of the detection position detected by the voltage detection unit can be 0V, or a value (intermediate value) greater than 0V and less than the threshold value. Both 0V and the intermediate value can be called low voltage. In some embodiments, the intermediate value can also be equal to the threshold value.

[0058] (Device under test)

[0059] The detected device 2 includes a switch assembly 2a, an intermediate conductive member 2b, a terminal conductive member 2c and a control member 2d, wherein at least a portion of the switch assembly 2a, the intermediate conductive member 2b and the terminal conductive member 2c are made of conductive material and are electrically connected in sequence; preferably, the switch assembly 2a is not arranged at the non-driving end NF, at least a portion of the intermediate conductive member 2b extends along the first direction, and at least a portion of the terminal conductive member 2c is located at the non-driving end NF. When the developing box 100 is installed in the imaging device, the terminal conductive member 2c is electrically connected to the detection device PE, and the control member 2d is used to control the switch assembly 2a to switch between the first state and the second state; Figure 3 As shown, the terminal conductive member 2c includes a conductive support 14 and an electrode 88 which are electrically connected to each other, the conductive support 14 is used to support the developing roller 11 and / or the powder feeding roller 16, and the electrode 88 is used to be electrically connected / contacted with the abutted end 127; preferably, after the developing box 100 is installed in the imaging device, or in other words, when the developing box 100 is installed in the imaging device, the terminal conductive member 2c is always electrically connected to the detection device PE, so that the detected device 2 can obtain a stable voltage supply.

[0060] Commonly used, the developing roller 11 and the powder feeding roller 16 both include a rotating shaft extending along a first direction and a coating layer coated on the outer surface of the rotating shaft, and the rotating shaft and the coating layer are preferably made of metal. For example, the developing roller 11 includes a developing roller shaft 111 extending along the first direction and a developing layer 112 coated on the outer surface of the developing roller shaft, and the carbon powder is carried by the developing layer 112. The powder feeding roller 16 includes a powder feeding roller rotating shaft 161 extending along the first direction and a powder feeding layer coated on the outer surface of the powder feeding roller rotating shaft. Therefore, the developing roller shaft 111 and the powder feeding roller shaft 161 can both be regarded as an intermediate conductive member 2b; the developing roller shaft 111 and / or the powder feeding roller shaft 161 are electrically connected to the conductive bracket 14, so that the on-off assembly 2a is electrically connected to the terminal conductive member 2c through the developing roller shaft 111 and / or the powder feeding roller shaft 161.

[0061] The switch assembly 2a includes a first conductive member 21, a second conductive member 22 and a third conductive member 23, wherein at least a portion of the third conductive member 23 is configured to be movable relative to the housing 1, and has a first connection end 231 and a second connection end 232, wherein the first connection end 231 is used to electrically connect to the first conductive member 21, and the second connection end 232 is used to electrically connect to the second conductive member 22, and the first conductive member 21 is also used for direct grounding, and the second conductive member 22 has a third connection end 221 and a fourth connection end 222, wherein the third connection end 221 is used to electrically connect to the second connection end 232, and the fourth connection end 222 is used to electrically connect to the intermediate conductive member 2b.

[0062] The control member 2d is arranged to be movable relative to the housing 1. Specifically, the control member 2d receives the driving force of the driving force receiving member 13 through the driving force transmission component 3 and moves. The movement mode can be rotation, translation, or reciprocating swing. Figure 4 As shown, the control member 2d includes a driving force receiving part 2d1, a toggle part (dial block) 2d2 and a driving force disconnecting part 2d3, wherein the driving force receiving part 2d1 is used to cooperate with the driving force transmitting component 3 to receive the driving force, and the driving force disconnecting part 2d3 is used to disconnect the driving force transmitting component 3 from transmitting the driving force to the driving force receiving part 2d1. With the movement of the control member 2d, the toggle block 2d2 / control member 2d moves from the first position to the second position. In the first position, the on-off component 2a is in the first state, and the detection position has a first voltage value. In the second position, the on-off component 2a is in the second state, and the detection position has a second voltage value. The first voltage value is different from the second voltage value. When the detection device PE completes the detection, the driving force used to drive the control member 2d is disconnected by the driving force disconnecting part 2d3.

[0063] Continue as Figure 4 As shown, in this embodiment, preferably, the control member 2d is configured as a gear with a missing tooth portion, the driving force receiving portion 2d1 is the tooth portion of the gear, the driving force disconnecting portion 2d3 is the missing tooth portion of the gear, the shift block 2d2 is arranged on the gear, and the number of the shift blocks 2d2 can be set to one or more according to the detection requirements of the imaging device.

[0064] When the shift block 2d2 / control member 2d is in the first position where it does not contact the third conductive member 23,

[0065] (1) The third conductive member 23 is only electrically disconnected from the first conductive member 21. At this time, the first connection end 231 is electrically disconnected from the first conductive member 21, but the second connection end 232 is electrically connected to the third connection end 221. For this situation, see Figure 5A and Fig. 7A As shown, at the same time, Figure 5A and Figure 5B An example is also given in which the fourth connection end 222 is electrically connected to the powder feeding roller shaft 161. Alternatively, the fourth connection end 222 may also be electrically connected to the developing roller shaft 111; or

[0066] (2) The third conductive member 23 is only electrically disconnected from the second conductive member 22. In this case, the first connection end 231 is electrically connected to the first conductive member 21, but the second connection end 232 is electrically disconnected from the third connection end 221; or

[0067] (3) The first conductive member 21 and the second conductive member 22 are simultaneously disconnected from the third conductive member 23. At this time, the first connection end 231 is disconnected from the first conductive member 21, and the second connection end 232 is also disconnected from the third connection end 221.

[0068] For the detected device 2, since the electrical connection of the on-off component 2a is disconnected, the voltage value applied by the power supply to the developer box 100 (developer roller 11) is greater than the preset threshold value of the detection device PE, and the voltage can be detected by the voltage detection unit in the detection device PE, that is, the detection position has the high voltage, even if the electrical connection between the on-off component 2a and the intermediate conductive member 2b, the electrical connection between the intermediate conductive member 2b and the terminal conductive member 2c, and the electrical connection between the terminal conductive member 2c and the detection device PE / the abutted end 127 are still connected, the electrical connection of the detected device 2 is still in a disconnected state. At this time, the voltage value detected by the voltage detection unit in the detection device PE is a high voltage, and the imaging device records that the voltage value of the developer box 100 is detected once.

[0069] As the control member 2d rotates, the shift block 2d2 gradually reaches the second position in contact with the third conductive member 23 from the first position in which it is not in contact with the third conductive member 23. During the rotation of the control member 2d, or when the control member 2d rotates to reach the second position, the third conductive member 23 is electrically connected to the first conductive member 21 and the second conductive member 22 at the same time; for example, the third conductive member 23 is held by the retaining member in a holding state in which it is electrically disconnected from at least one of the first conductive member 21 and the second conductive member 22. The release of the holding state can be achieved by either shifting the retaining member by shifting 2d2 or shifting the third conductive member 23 by shifting 2d2.

[0070] Corresponding to the above situation (1), if Figure 5B and Figure 7B As shown, the shift block 2d2 pushes the first connection end 231 of the third conductive member 23 toward the first conductive member 21. In the second position, the first connection end 231 / the third conductive member 23 is electrically connected to the first conductive member 21. At this time, the electrical connection of the detection device 2 is connected, and the voltage applied by the power supply to the developing box 100 (developing roller 11) is grounded. The voltage value of the detection position detected by the detection device PE is 0V, which is less than the threshold value, that is, the low voltage, and the imaging device records that the voltage value of the developing box 100 is not detected.

[0071] As the control member 2d continues to rotate, the shift block 2d2 gradually loses contact with the third conductive member 23, and the first connecting end 231 returns to a position where it is not electrically connected to the first conductive member 21. The electrical connection of the detection device 2 is disconnected again, and the imaging device records the voltage value of the developing box 100 being detected again.

[0072] As described above, by intermittently acting on the first connecting end 231 by the shift block 2d2, the electrical connection of the detected device 2 is switched between disconnection and connection. The disconnection of the electrical connection means that no current path is formed inside the detected device 2, that is, the current cannot flow from one end of the detected device 2 to the other end. The disconnection method can be that the current path between at least any two adjacent components in the detected device 2 is disconnected. The connection of the electrical connection means that a current path is formed inside the detected device 2, that is, the current can flow from one end of the detected device 2 to the other end. Therefore, the voltage value applied to the developing box 100 by the imaging device detected by the voltage detection unit in the detection device PE is switched between the high voltage and the low voltage. Within a predetermined time, the high voltage and the low voltage appear alternately. When the voltage detection unit detects a high voltage, the imaging device obtains a high voltage signal. When the voltage detection unit detects a low voltage, the imaging device obtains a low voltage signal. As described above, the imaging device can obtain various parameter information of the developing box 100 based on the number of high voltage signals and / or the number of low voltage signals obtained within a predetermined time.

[0073] Embodiment 2

[0074] In some embodiments, the imaging device can also determine the parameter information of the developing box 100 based on the time interval between two adjacent voltage values ​​detected by the voltage detection unit at the detection position. The two adjacent voltage values ​​can be both low voltages, or both high voltages, or one can be a low voltage and the other can be a high voltage. That is, the imaging device can determine the parameter information of the developing box 100 based on the time interval between two adjacent low voltage signals, or the time interval between two adjacent high voltage signals, or the time interval between adjacent low voltage signals and high voltage signals.

[0075] The third conductive member 23 is preferably an elastic member made of conductive material, so that the third conductive member 23 itself has elasticity, and when external force is applied to the third conductive member 23, the third conductive member 23 can move relative to the shell 1; the above embodiment introduces that the third conductive member 23 is pushed by the shift block 2d2 and moves from a position not electrically connected to the first conductive member 21 to a position electrically connected to the first conductive member 21, and accordingly, the electrical connection of the detected device 2 is also changed from disconnection to connection, and when the shift block 2d2 no longer pushes the third conductive member 23, the third conductive member 23 returns from the position electrically connected to the first conductive member 21 to the position not electrically connected to the first conductive member 21 under the action of its own elastic force, and accordingly, the electrical connection of the detected device 2 is also changed from connection to disconnection.

[0076] In some embodiments, before the developing box 100 receives the driving force, the third conductive member 23 is pressed by the shift block 2d2 and remains not electrically connected to the first conductive member 21. As the control member 2d rotates, the shift block 2d2 gradually stops pressing the third conductive member 23. Under the action of its own elastic force, the third conductive member 23 is electrically connected to the first conductive member 21. Therefore, the shift block 2d2 can act on the third conductive member 23 / first connecting end 231 by pushing / moving or by pressing.

[0077] As described above, for the control member 2d, its movement mode can be not only rotation, but also translation or reciprocating swing, that is, the control member 2d has at least one of rotation, translation and swing. For example, the control member 2d is configured to slide between a first position and a second position along a predetermined path, and the predetermined path can be either a straight path or a curved path, or the control member 2d is configured to rotate around a predetermined rotation axis, or the control member 2d is configured to swing reciprocatingly around a predetermined rotation axis.

[0078] In some embodiments, before the developing box 100 receives the driving force, under the elastic force of the third conductive member 23, or under the action of the control member 2d / shift block 2d2, the third conductive member 23 remains electrically connected to the first conductive member 21. At this time, the electrical connection of the detected device 2 is in a connected state. As the control member 2d rotates, the shift block 2d2 gradually begins to act on the third conductive member 23, and the third conductive member 23 moves from a position electrically connected to the first conductive member 21 to a position not electrically connected to the first conductive member 21. At this time, the electrical connection of the detected device 2 is in a disconnected state.

[0079] For the third conductive member 23, when the third conductive member 23 is a rigid body, the detected device 2 also needs to be provided with a reset member for forcing the third conductive member 23 to reset; optionally, when the developing box 100 is configured so that only a low voltage or a high voltage needs to be detected once by the detection device PE, the reset member may not be provided.

[0080] According to the above description, in one embodiment, the first position may refer to the position where the control member 2d / shift block 2d2 is not in contact with the third conductive member 23, and the on-off component 2a is in the first state. According to the positional relationship between the third conductive member 23 and the first conductive member 21, the on-off component 2a may be in the disconnected state. At this time, the electrical connection of the detected device 2 is also in the disconnected state, and the first voltage value is a high voltage. The on-off component 2a may also be in the connected state. At this time, the electrical connection of the detected device 2 is also in the connected state, and the first voltage value is a low voltage. Correspondingly, the second position refers to the position where the control member 2d / shift block 2d2 is in contact with the third conductive member 23, and the on-off component 2a is in the second state. According to the positional relationship between the third conductive member 23 and the first conductive member 21, the on-off component 2a may be in the connected state. At this time, the electrical connection of the detected device 2 is also in the connected state, and the second voltage value is a low voltage. The on-off component 2a may also be in the disconnected state. At this time, the electrical connection of the detected device 2 is also in the disconnected state, and the second voltage value is a high voltage.

[0081] In another embodiment, the first position may also refer to the position where the control member 2d / shift block 2d2 is in contact with the third conductive member 23, and the on-off component 2a is in the first state. According to the positional relationship between the third conductive member 23 and the first conductive member 21, the on-off component 2a may be in the disconnected state, at which time, the electrical connection of the detected device 2 is in the disconnected state, and the first voltage value is a high voltage. The on-off component 2a may also be in the connected state, at which time, the electrical connection of the detected device 2 is also in the connected state, and the first voltage value is a low voltage. Correspondingly, the second position may also refer to the position where the control member 2d / shift block 2d2 is not in contact with the third conductive member 23, and the on-off component 2a is in the second state. According to the positional relationship between the third conductive member 23 and the first conductive member 21, the on-off component 2a may be in the connected state, at which time, the electrical connection of the detected device 2 is also in the connected state, and the second voltage value is a low voltage. The on-off component 2a may also be in the disconnected state, at which time, the electrical connection of the detected device 2 is also in the disconnected state, and the second voltage value is a high voltage.

[0082] In a simplified embodiment, the second conductive member 22 can also be omitted. In this case, the third conductive member 23 can be directly electrically connected to the intermediate conductive member 2b. Under this idea, even if the second conductive member 22 is still provided, the combination of the second conductive member 22 and the third conductive member 23 can also be considered as a new third conductive member, at least a portion of which can move relative to the shell 1, and the new third conductive member is also electrically connected to the intermediate conductive member 2b.

[0083] The intermediate conductive member 2b may be the developer roller shaft 111 described above, or may be the developer layer 112 or the powder feeding roller shaft 161 or the powder feeding layer. When the stirring member is made of a conductive material, the intermediate conductive member 2b may also be a stirring frame for stirring the carbon powder in the housing 1. The stirring frame may be used to prevent the carbon powder from agglomerating and may also be used to transport the carbon powder to the powder feeding roller 16 / developer roller 11. Figure 3 As shown, the shell 1 includes a first shell 1a and a second shell 1b combined with each other, a cavity for accommodating carbon powder is formed between the first shell 1a and the second shell 1b, and the intermediate conductive part 2b can also be at least one of the first shell 1a and the second shell 1b; when the shell 1 is formed as a whole, the intermediate conductive part 2b can also be the shell 1.

[0084] In a simplified embodiment, a conductor extending along the first direction may be further installed in the developer box 100, one end of the conductor being used to electrically connect to the on-off assembly 2a, and the other end being used to electrically connect to the terminal conductive member 2c. The conductor may be rotatably arranged in the developer box or fixedly arranged on the housing 1. In this case, the intermediate conductive member 2b is the conductor. The conductor may be formed as a rigid body such as the developer roller shaft 111 or a flexible body such as a metal sheet. In the above embodiment, the rotating member and the housing made of conductive material may be regarded as the conductor. In other embodiments, the conductor may be a powder knife, a sealing blade, etc. extending along the first direction and contacting the surface of the developer roller 11 (the surface of the developer layer 112). The powder knife is fixedly installed in the housing 1 for adjusting the thickness of the carbon powder layer on the surface of the developer roller 11. The sealing blade is a flexible sheet for sealing the space between the developer roller 11 and the housing 1 to prevent carbon powder from leaking from the space.

[0085] No matter how the intermediate conductive member 2b is arranged, it is sufficient as long as the voltage value at the detection position can meet the detection requirement of the detection device PE.

[0086] In some embodiments, a portion of the on-off component 2a is configured to extend along the first direction. For example, a portion of the third conductive member 23 extends from the driving end F to the non-driving end NF and forms an electrical connection with the end conductive member 2c. At the same time, a voltage drop element that can meet the detection requirements is provided in the on-off component 2a, so that the voltage value at the detection position can meet the detection requirements of the detection device PE. At this time, the intermediate conductive member 2b can be regarded as not existing.

[0087] In some embodiments, the terminal conductive member 2c is simplified to only have a conductive bracket 14, which is electrically connected to the developing roller 11 and / or the powder feeding roller 16. When the developing box 100 is installed in the imaging device, the conductive bracket 14 is also electrically connected to the abutted end 127; or, the terminal conductive member 2c is simplified to only have an electrode 88, which is electrically connected to the developing roller 11 and / or the powder feeding roller 16. When the developing box 100 is installed in the imaging device, the electrode 88 is also always electrically connected to the abutted end 127. In this way, the developing box 100 is electrically connected to the detection device PE through the terminal conductive member 2c so that the developing roller 11 and the powder feeding roller 16 receive the power supplied by the imaging device.

[0088] Since the developing layer 112 is directly exposed to the shell 1, according to the above description, when the intermediate conductive member 2b is the developing layer 112, compared with the contact between the terminal conductive member 2c and the developing roller shaft 111 or the powder feeding layer or the powder feeding roller shaft 161, the contact between the terminal conductive member 2c and the developing layer 112 is easier to achieve and the contact is more stable. Furthermore, when the terminal conductive member 2c is simplified to only set the conductive bracket 14 or only set the electrode 88, the conductive bracket 14 or the electrode 88 directly contacts the developing layer 112, and a portion of the conductive bracket 14 or the electrode 88 is located at the non-driving end NF. Further, in some embodiments, the detected device 2 can also be configured so that when the developer box 100 is installed on the imaging device, the on-off component 2a extends to one end of the non-driving end NF and is electrically connected to the abutted end 127. At this time, the terminal conductive member 2c can also be regarded as not existing, and the detected device 2 is simplified to the on-off component 2a. Based on this embodiment, it is achievable that the developer box 100 can also be configured so that the developing roller 11 and the powder feeding roller 16 receive the power supplied by the imaging device without being electrically connected to the detection device PE / the abutted end 127 through the terminal conductive member 2c. For example, by further providing a conductive member in the developer box, the additional conductive member is used to receive the power supplied by the imaging device for the developing roller 11 and / or the powder feeding roller 16, and the control member 2d is used to control the on-off of the electrical connection between the on-off component 2a and the abutted end 127. At this time, according to the above-mentioned deformation method, before the developer box 100 receives the driving force, the on-off component 2a and the abutted end 127 can be in an electrically connected state or in an electrically disconnected state.

[0089] As described above, the first voltage value may be a high voltage or a low voltage, wherein the low voltage is 0V or the intermediate value. To this end, the present invention also has a variation in which an impedance element 25 (such as Fig. 8A and Figure 8B As shown), the voltage value carried by the impedance element 25 is the intermediate value, that is, the voltage value carried by the impedance element 25 can also be regarded as a low voltage.

[0090] Specifically, Fig. 8A As shown, one end of the impedance element 25 is electrically connected to the first conductive member 21, and the other end is grounded, that is, the first conductive member 21 is indirectly grounded through the impedance element 25. When the shift block 2d2 / control member 2d is in the first position, the electrical connection between the third conductive member 23 and the first conductive member 21 is disconnected, the electrical connection of the on-off assembly 2a is in the first disconnected state, the electrical connection of the detection device 2 is also disconnected, and the first voltage value of the detection position detected by the detection device PE is a high voltage. The imaging device records that the voltage value of the developer box 100 is detected.

[0091] like Figure 8B As shown, when the driving force receiving member 13 receives the driving force, the shift block 2d2 / control member 2d moves from the first position to the second position, and the on-off assembly 2a gradually changes from the first state of disconnected electrical connection to the second state of connected electrical connection. At the same time, the electrical connection of the detected device 2 also changes from disconnected to connected, until the third conductive member 23 is electrically connected to the first conductive member 21, the detected device 2 is grounded, the voltage applied by the power supply to the developing box 100 (developing roller 11) is grounded, and the second voltage value of the detection position detected by the detection device PE is the low voltage (intermediate value) carried by the impedance element 25, and the imaging device records that the voltage value of the developing box 100 is not detected. In some embodiments, the impedance element 25 can also be arranged between the first conductive member 21 and the electrode 88, and the first conductive member 21 is grounded; specifically, the grounding method of the first conductive member 21 or the impedance element 25 can be directly electrically connected to the grounding member in the imaging device, or it can be electrically connected to the photosensitive drum and grounded through the photosensitive drum.

[0092] When the low voltage is an intermediate value, in some embodiments, in the first state, the electrical connection of the on-off component 2a is in a connected state, at which time the first voltage value is a low voltage, and in the second state, the electrical connection of the on-off component 2a is in a disconnected state, at which time the second voltage value is a high voltage.

[0093] Preferably, the impedance element 25 is a resistor, and its resistance is no more than 1 MΩ.

[0094] It can be seen that the switch block 2d2 / control component 2d can be used to control the switching of the on-off component 2a between the first state and the second state. When the switch block 2d2 / control component 2d is located in the first position, the on-off component 2a is in the first state. At this time, the on-off component 2a can be in a connected state or a disconnected state. Correspondingly, the electrical connection of the detected device 2 can be in a connected state or a disconnected state. At this time, the detection position has a first voltage value; when the switch block 2d2 / control component 2d is located in the second position, the on-off component 2a is in the second state, the electrical connection of the detected device 2 is in a connected state, and the detection position has a second voltage value. The first voltage value is different from the second voltage value.

[0095] In some embodiments, based on the inventive concept of the present invention, the control component 2d can also be set at the non-driving end NF. For example, a rotating component is used to transmit the driving force from the driving end F to the non-driving end NF. Specifically, a gear can be installed at the non-driving end of the developing roller 11 or the powder feeding roller 16, and the control component 2d is driven by the gear; further, the on-off component 2a can also be set at the non-driving end NF. At this time, the first conductive component 21 will be grounded at the non-driving end NF of the developing box 100; therefore, the control component 2d and the on-off component 2a can be set at either the driving end F or the non-driving end NF.

[0096] In practice, there are both imaging devices that supply positive voltage to the developer box 100 and imaging devices that supply negative voltage to the developer box 100. However, based on the inventive concept of the present invention, it should be understood that the above-mentioned first voltage value and the second voltage value both refer to the absolute values ​​of the voltage values. Regardless of whether it is the imaging device that supplies positive voltage or the imaging device that supplies negative voltage, the technical solution involved in the present invention is applicable.

[0097] Embodiment 3

[0098] On the basis of the above embodiment, this embodiment focuses on describing the implementation structure of the first conductive member 21 , and the same structure as the above embodiment will not be repeated, and the same component numbers as the above embodiment will be directly quoted in this embodiment.

[0099] like Fig. 9As shown, the processing box 100 also includes a protective member 17 detachably combined with the chip frame 15, and the protective member 17 is used to protect the chip assembly carried by the chip frame 15. The first conductive member 21 is movably arranged on at least one of the shell 1, the end cover 12 and the chip frame 15. When the protective member 17 is installed to the chip frame 15, the first conductive member 21 is in a retracted state and is protected by the protective member 17. When the protective member 17 is removed from the chip frame 15, the first conductive member 21 reaches an extended state from the retracted state. The first conductive member 21 in the extended state can be connected to a low voltage. For example, the first conductive member 21 is directly or indirectly grounded. Specifically, the first conductive member 21 is directly or indirectly abutted against a metal part in the imaging device and is grounded.

[0100] That is to say, at least a portion of the first conductive member 21 is movably disposed on at least one of the shell 1, the end cover 12 and the chip rack 15, and at least a portion of the first conductive member 21 is configured to be movable between a retracted state and an extended state. In the retracted state, at least a portion of the first conductive member 21 is protected by the protective member 17, and in the extended state, at least a portion of the first conductive member 21 can be directly or indirectly grounded.

[0101] Hereinafter, the first conductive member 21 is movably disposed on the chip frame 15 as an example for description.

[0102] The chip rack 15 includes a chip rack body 151 and a chip mounting portion 152. The chip rack body 151 is connected to the end cover 12 or the shell 1. The chip assembly is provided with an electrical contact portion for electrically contacting the contact pin. In the chip assembly, at least the electrical contact portion is arranged on the chip mounting portion 152, and the first conductive member 21 is arranged on the chip rack body 151.

[0103] like Fig. 9 and Fig.10 As shown, the developing box 100 also includes a movable component 30, and the movable component 30 is used to ground the third conductive member 23. Specifically, one end of the movable component 30 is used to be electrically connected to the third conductive member 23. In practice, whether one end of the movable component 30 is electrically connected to the third conductive member can be controlled according to the method described in the above embodiment. The other end of the movable component 30 is used for direct or indirect grounding. This embodiment focuses on describing the other end of the movable component 30 for direct or indirect grounding.

[0104] The movable component 30 includes a support seat 31 and a first conductive member 21, wherein the support seat 31 is configured as a part of the chip frame 151, so that the space occupied by the chip frame 15 can be fully utilized, thereby the first conductive member 21 can be effectively disposed without increasing the size of the developing box 100.

[0105] In this embodiment, the first conductive member 21 includes a movable member 32 and an elastic member 33 which are separately arranged. The elastic member 33 is used to push the movable member 32 toward the extended state. At least a portion of the movable member 32 and at least a portion of the elastic member 33 are made of conductive material, such as Fig.10 As shown, the movable member 32 is formed as a conductive block made of conductive material, and the movable member 32 includes a movable portion 321 and a contact portion 322, and the contact portion 322 is used to directly or indirectly contact with a metal component in the imaging device, and the movable portion 321 enables the movable member 32 to be arranged on the support seat 31 in a movable manner, for example, the movable member 32 is arranged in a rotatable manner, or in a slidable manner, etc. In this embodiment, the movable portion 321 and the support seat 31 are arranged to be matched with a shaft hole, Fig.10 In the figure, the movable part 321 is provided with a shaft, and the support seat 31 is provided with a hole for cooperating with the shaft, so that the movable part 321 can rotate relative to the support seat 31; the elastic member 33 is preferably a torsion spring, and has a first end 331 for contacting the third conductive member 23 and a second end 332 for contacting the movable member 32. With the movement of the control member 2d, whether the first end 331 of the elastic member 33 and the third conductive member 23 are in an electrically connected state (that is, the two are in contact or out of contact) can be controlled.

[0106] Furthermore, the chip rack 15 is also provided with a receiving cavity 153, so as to more clearly observe the retracted state of the first conductive member 21. Fig.11 Although the protective member 17 is not shown in the figure, it should be understood that at least a portion of the chip frame body 151 and at least a portion of the movable component 30 are both contained / wrapped by the protective member 17 and protected; Fig.11 As shown, at least the movable member 32 is received by the receiving cavity 153 , and preferably, the elastic member 33 is also received by the receiving cavity 153 .

[0107] When the protective member 17 is removed from the chip frame 15, the elastic member 33 releases its elastic force, and the movable member 32 rotates / turns around the axis and protrudes from the receiving cavity 153. Fig. 9 As shown, the first conductive member 21 is in the extended state and the movable member 32 can directly or indirectly abut against a metal component in the imaging device.

[0108] In some embodiments, a guiding mechanism may also be provided for the movable part 32. When the protective part 17 is installed along a first direction from the driving end F toward the non-driving end NF, the movable part 32 may be pushed by the protective part 17 to overcome the elastic force of the elastic part 33, and move from a state of protruding from the installation cavity 153 to a state of being received in the receiving cavity 153. During this process, the user or the developer box assembler does not have to specifically operate the movable part 32, thereby improving the operating efficiency.

[0109] It should be noted that the installation direction of the protective member 17 does not necessarily have to be along the first direction. Based on the inventive concept of the present invention, the protective member 17 can also be installed along a direction intersecting with the first direction. It should be understood that the hole in the shaft hole matching can be either a through hole or a groove formed as a blind hole.

[0110] Embodiment 4

[0111] In this embodiment, the first conductive member 21 is still configured to be movable between an extended state and a retracted state. Fig.12 As shown, the movable component 30 still includes a mounting seat 31 and a first conductive member 21, and the mounting seat 31 is still formed as a part of the chip frame body 151. The first conductive member 21 in this embodiment includes a movable member 32, an elastic member 33 and a transition member 34, wherein the movable member 32 moves in a sliding manner, and at least a part of the movable member 32 is made of conductive material, including a movable portion 321 and a contact portion 322, wherein the movable portion 321 is slidably arranged on the mounting seat 31, and the contact portion 322 is used to directly or indirectly abut against metal parts in the imaging device.

[0112] Preferably, the movable portion 321 and the mounting seat 31 are also matched with an axial hole, and the movable portion 321 includes at least one of a first guide portion 321a and a second guide portion 321b. Correspondingly, the mounting seat 31 is provided with a first guided portion 154 and a second guided portion 155. Fig.12 As shown, the first guiding portion 321a is configured as a hole, the first guided portion 154 is configured as an axis, the second guiding portion 321b is configured as an axis, and the second guided portion 155 is configured as a hole.

[0113] When the first guiding portion 321 a , the second guiding portion 321 b , the first guided portion 154 , and the second guided portion 155 are provided at the same time, the movement trajectory of the movable member 32 will be more accurate.

[0114] In some embodiments, when cut along a plane perpendicular to the joining direction of the first guiding portion 321a and the first guided portion 154, the cross-sections of the first guiding portion 321a and the first guided portion 154 are non-circular, for example, the cross-sections are irregular, triangular, trapezoidal, etc. Through such a setting, the first guiding portion 321a and the first guided portion 154 can be effectively prevented from relative rotation, so that the movement trajectory of the movable part 32 will be more precise.

[0115] In some embodiments, the second guiding portion 321b and the second guided portion 155 may also have the above-mentioned structure, so that it can be extended that the cross-section of at least one of the first guiding portion 321a and the first guided portion 154 is non-circular, and / or the cross-section of at least one of the second guiding portion 321b and the second guided portion 155 is non-circular.

[0116] The elastic member 33 is used to push the movable member 32 toward the extended state, and is formed as a compression spring or a tension spring. At least a portion of the adapter 34 is made of a conductive material, and has a first adapter portion 341, a second adapter portion 342 and a fixed portion 343. The first adapter portion 341 maintains contact with a contact surface 323 provided in the movable member 32, the second adapter portion 342 is used to be electrically connected to the third conductive member 23, and the fixed portion 343 is used to fix the adapter 34 on at least one of the chip frame 15, the end cover 12 and the housing 1.

[0117] Continue as Fig.12 As shown, the chip rack 15 is also provided with a receiving cavity 153, and at least a portion of the first guided portion 154 and at least a portion of the second guided portion 155 are arranged in the receiving cavity 153. Fig.13A As shown, under the elastic force of the elastic member 33, the contact portion 322 protrudes from the receiving cavity 153. At this time, the first conductive member 21 can be regarded as being in an extended state, and the contact surface 323 is in contact with the first adapter portion 341. As the protective member 17 is installed, through the cooperation of the guiding portion and the guided portion, the movable member 32 overcomes the elastic force of the elastic member 33 and is received in the receiving cavity 153, and the elastic member 33 is elastically deformed and accumulates elastic force. At this time, the first conductive member 21 can be regarded as being in a retracted state, and the contact surface 323 and the first adapter portion 341 can be kept in contact or out of contact.

[0118] When the protective member 17 is removed from the chip frame 15, the elastic member 33 releases its elastic force, and through the cooperation of the guiding part and the guided part, the movable member 32 protrudes out of the storage cavity 153 again, and the first conductive member 21 returns from the retracted state to the extended state, and the movable member 32 can directly or indirectly abut against the metal parts in the imaging device.

[0119] Similarly, in this embodiment, whether the second adapter 342 and the third conductive member 23 are in an electrically connected state can be controlled by the movement of the control member 2d; the installation and disassembly direction of the protective member 17 can be parallel to the first direction or intersecting with the first direction; the movable member 32 can also be provided with the above-mentioned guiding mechanism, so that the user or the developer box assembler does not have to specifically operate the movable member 32, thereby improving the operating efficiency.

[0120] Embodiment 5

[0121] The same structure as that of Embodiment 3 and Embodiment 4 will not be described again. The difference is that the movable part 32 in this embodiment is made of a smaller conductive material. For example, the movable part 32 in this embodiment is made of metal wire. The movable part 32 made of metal wire can form an electrical connection with the third conductive part 23 in a direct contact manner, or the two can form an electrical connection in an indirect contact manner. Furthermore, under the action of the elastic part 33, the movable part 32 made of metal wire can be movable relative to the support seat 31, and its movable mode can be rotation or sliding.

[0122] like Fig.14 As shown, the movable member 32 in this embodiment is arranged in a rotatable manner, and the movable member 32 still has a movable portion 321 and a contact portion 322, wherein the movable portion 321 is used to contact the second end 332 of the elastic member 33, and the contact portion 322 is used to directly or indirectly abut against a metal component in the imaging device; further, the first conductive member 21 also includes a movable block 35 that can be movably arranged, at least a portion of the movable member 32 is arranged on the movable block 35, and the movable block 35 is made of non-conductive material and can be rotatably arranged or slidably arranged, so that at least a portion of the movable member 32 can move with the movement of the movable block 35.

[0123] In some embodiments, the movable block 35 is further provided with a receiving groove 351 for receiving at least a portion of the movable member 32 , so that the movable member 32 will have a more precise motion trajectory.

[0124] like Fig.15 As shown, the chip rack 15 has the storage cavity 153. When the protective member 17 is not installed, under the action of the elastic member 33, the contact portion 322 protrudes from the storage cavity 153. At this time, the first conductive member 21 is in an extended state. As the protective member 17 is installed, the movable member 32 / movable block 35 overcomes the elastic force of the elastic member 33 and moves toward the state of being stored / retracted by the storage cavity 153. At this time, the first conductive member 21 is in a retracted state. When the protective member 17 is removed, the elastic member 33 releases the elastic force, and the contact portion 322 protrudes from the storage cavity 153 again. At this time, the first conductive member 21 is in an extended state again.

[0125] In some embodiments, the elastic member 33 is configured as a torsion spring for pushing the movable member 32 toward the extended state. According to the above description, the elastic member 33 can directly push the movable member 32 toward the extended state, or it can push the movable block 35 to achieve the pushing of the movable member 32 toward the extended state.

[0126] In some embodiments, the movable member 32 and the elastic member 33 are formed integrally. In this case, the movable member 32 will become a part of the elastic member 33, and the first end 331 of the elastic member 33 contacts the third conductive member 23, so that the movable member 32 and the third conductive member 23 are electrically connected. At the same time, the elastic member 33 also abuts against the movable block 35, so that the movable block 35 drives the contact portion 322 / the first conductive member 21 to move toward the retracted state.

[0127] In some embodiments, the movable portion 321 is in direct contact with the third conductive member 23. At this time, the elastic member 33 only serves to push the movable block 35. Since at least a portion of the movable member 32 is disposed on the movable block 35, in this structure, the elastic member 33 still has a tendency to move the contact portion 322 / the first conductive member 21 toward the retracted state.

[0128] In some embodiments, when the first conductive member 21 is grounded at the non-driving end, the first conductive member 21 can still be configured to be movable between the retracted state and the extended state as described in the third, fourth, and fifth embodiments above.

[0129] [Beneficial Effects]

[0130] 1. When the developer box 100 is installed in the imaging device, the conductive member (a part of the detection device 2) located at the non-driving end NF is electrically connected to / contacted with the detection device PE / the abutted end 127 in the imaging device, and as long as the developer box 100 is not removed from the imaging device, the electrical connection / contact between the conductive member and the abutted end 127 will be maintained. Therefore, the non-driving end NF does not need to be provided with a shifting block for shifting the abutted end 127, and the structure of the non-driving end NF can be simplified.

[0131] Specifically, the conductive member may be the terminal conductive member 2c, or may be the intermediate conductive member 2b, or may be the switching component 2a.

[0132] 2. According to the above description, as long as the on-off component 2a can receive the driving force of the driving force receiving component 13, there can be multiple settings. For example, the on-off component 2a is set at the driving end F, or at the non-driving end NF, or between the driving end F and the non-driving end NF. Similarly, the control component 2d for controlling the connection and disconnection of the on-off component 2a also has the above-mentioned multiple setting positions, and the design freedom of the shift block 2d2 / control component 2d can be improved.

[0133] 3. According to the inventive concept of the present invention, in some of the above embodiments, although a conductive member extending in the first direction needs to be provided in the detection device 2, the provision of the conductive member is simpler than that of a member for transmitting driving force, and the structure of the developing box 100 also becomes simpler.

[0134] 4. In the movable component 30 / detected device 2, the first conductive member 21 is configured to move between an extended state and a retracted state. Before the developing box 100 is used, the first conductive member 21 can be in a retracted state. In this way, the packaging size of the developing box 100 does not need to be increased, and the first conductive member 21 can be prevented from breaking or wearing during the transportation of the developing box 100.

[0135] 5. The mounting seat 31 of the movable component 30 is configured as a part of the chip frame body 151. This structure can fully utilize the space of the chip frame body 151, so that even if the movable component 30 is set in the developing box 100, the overall size of the developing box 100 will not change.

[0136] 6. The provision of the protective member 17 not only protects at least a portion of the movable assembly 30, but also when the chip holder 15 is configured to be movable relative to the shell 1 / end cover 12, the chip holder 15 can be temporarily positioned by the protective member 17 and cannot move until the protective member 17 is removed, thereby effectively preventing the chip holder 15 from moving relative to the shell 1 / end cover 12 and falling off, or being collided, or the chip assembly from being worn, etc. before the developer box 100 is used.
