Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a toner box and an image forming device. Background Art

[0002] Printing equipment is a commonly used office equipment in existing offices. Among them, there is a laser printing equipment that prints using the principle of laser imaging. During the imaging process of the laser printing equipment, the laser unit emits laser to the photosensitive drum of the developer box loaded with colorant. The charge on the surface of the photosensitive drum forms a charge with a different polarity from other positions at the position scanned by the laser, thereby forming an electrostatic latent image on the photosensitive drum. The developing roller further uses the potential difference caused by the electrostatic latent image to supply toner to the surface of the photosensitive drum to form an image. The photosensitive drum then transfers the image to a recording medium such as paper through a transfer unit, and finally is heated and fixed by a fixing unit to form an image on the recording medium.

[0003] Most of the current developer cartridges have a detection component for checking whether the developer cartridge is new, so that the printer can monitor the toner storage status inside the developer cartridge and remind the user to replace the toner when it is insufficient. The developer cartridge in the prior art integrates the detection component on one side of the gear set so that it rotates with the rotation of the driving gear. However, the detection component needs to have a certain size when cooperating with the detection component on the laser printing device, otherwise it may cause detection loss due to accuracy problems, and it is impossible to identify whether it is a new developer cartridge through the detection component. However, if the detection component is large in size, it will further occupy the size of the developer cartridge in the side depth direction, making it impossible to reduce the size of the developer cartridge. In addition, the components on the side of the gear set will cause problems such as reduced transmission accuracy due to the integration of too many components. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide a toner cartridge and an image forming device.

[0005] In a first aspect, the present invention provides a toner cartridge, which is applied to an image forming device, comprising:

[0006] A housing, wherein the housing has a middle wall and a first side wall and a second side wall located at two ends of the middle wall, and a storage cavity for storing toner is formed inside the housing;

[0007] a developing roller, rotatably disposed in the housing and in contact with an outer surface of the photosensitive member located outside the receiving chamber, for transferring the toner in the receiving chamber to the photosensitive member;

[0008] a stirring member, rotatably disposed in the receiving chamber, and used for stirring the toner in the receiving chamber;

[0009] A driving gear, used for receiving a driving force from the outside of the toner cartridge, and disposed on the first side wall of the housing;

[0010] a transmission gear set meshing with the driving gear and transmitting the driving force to the developing roller and the stirring member;

[0011] A detection rotating member, disposed on the housing, located on the second side wall or closer to the second side wall than the first side wall, and capable of transmitting detection information to a detection component of the image forming device under a rotational action;

[0012] an intermediate transmission shaft, the intermediate transmission shaft having a first end portion penetrating the first side wall, and a second end portion disposed at the second side wall or closer to the second side wall than the first side wall, the first end portion being meshed with one of the gears in the transmission gear set for transmitting the driving force to the detection rotating member;

[0013] Wherein, a first rotation axis formed by the rotational movement of the detection rotating member is perpendicular to a second rotation axis formed by the rotational movement of the intermediate transmission shaft, and the second rotation axis is parallel to the rotation axis of the driving gear.

[0014] According to the toner box of the first embodiment of the present invention, the first gear and the second gear for transmitting power to the developing roller and the stirring member are integrated on the side with the driving gear, which can improve the power transmission accuracy, and the detection rotating member is arranged at the other side away from the side, which solves the problem of excessive integration of the detection rotating member on the side with the driving gear in the prior art, and according to the implementation method, the space utilization rate of the developing box can be improved, and in the arrangement mode in which the detection rotating member is perpendicular to the rotation axis of the intermediate transmission shaft, the radial part with a larger area of ​​the detection gear can be parallel to the outer side wall of the shell, and the axial part with a narrower size can be effectively arranged in the toner box to reduce the influence caused by the size, and solves the problem of the detection rotating member protruding toward the outside of the toner box and thus lengthening the length of the toner box in the prior art. At the same time, because the detection rotating member is arranged at this position and uses the intermediate transmission shaft to transmit power, the transmission chain between the detection rotating member and the driving gear can be lengthened, and the detection rotating member is prevented from being placed between the transmission gear group and idling after the detection is completed, which affects the transmission accuracy of other important components such as the developing roller, the stirring member, etc., and shortens the transmission chain between the important components and the driving gear.

[0015] In a preferred embodiment of the present invention, when the colorant box is installed in the image forming device and the image forming device is in use, the intermediate transmission shaft is located above the stirring member, and the detection rotating member is located on a side of the intermediate transmission shaft away from the storage chamber.

[0016] In a preferred embodiment of the present invention, the intermediate transmission shaft is separated from the storage cavity by the intermediate wall, and the intermediate wall is provided with a placement groove arranged along the length direction and concave toward the storage cavity, and the intermediate transmission shaft is placed in the placement groove.

[0017] In a preferred embodiment of the present invention, the detection rotating member includes at least the following two states:

[0018] a first state, in which the detection rotating member is meshed with the intermediate transmission shaft and can receive a driving force from the intermediate transmission shaft to perform a rotation action;

[0019] a second state, in which the detection rotating member is disengaged from the intermediate transmission shaft;

[0020] Wherein, when the detection rotating member is in the first state and is driven by the intermediate transmission shaft to rotate by a preset angle, the detection rotating member switches from the first state to the second state.

[0022] The detection rotating member comprises a first portion and a second portion distributed along the first rotation axis, the first portion having an engagement surface engaged with the second end portion of the intermediate transmission shaft, and the second portion having a terminating portion and at least one counting portion arranged circumferentially around the first rotation axis;

[0023] In the rotation direction of the detection rotating member, the terminating portion is located at a downstream position of the last counting portion of the at least one counting portion, and the detection information transmitting member has a contact portion for contacting each of the counting portions and the terminating portion;

[0024] Wherein, when the detection rotating member is in the initial position of the first state, each of the counting parts contacts the contact part in sequence after being driven to rotate by the intermediate transmission shaft, so that the detection information transmission member performs a swing in each contact process;

[0025] When the detecting rotary member is in the second state, the contact portion is in contact with the stop portion.

[0026] In a preferred embodiment of the present invention, there is a counting gap between adjacent counting parts and between the counting parts and the terminating part, the detection information transmission member has a first posture and a second posture, and has a potential to rotate from the first posture toward the second posture direction;

[0027] Wherein, when the detection rotating member is in the first state, each time the counting part contacts the contact part, the detection information transmission member overcomes the accumulation force and moves from the second posture to the first posture, and when the contact part breaks away from the contact with the corresponding counting part and enters the counting gap, the accumulation force causes the detection rotating member to move from the first posture to the second posture;

[0028] Wherein, when the detection rotating member is in the initial position of the first state, the detection information transmission member is in the first posture, and when the detection rotating member is in the second state, the detection information transmission member is in the second posture.

[0029] In a preferred embodiment of the present invention, the intermediate transmission shaft has conical teeth on the second end portion, and the engagement surface includes an engagement tooth shape and a separation portion arranged circumferentially around the first rotation axis, and when the detection rotating member is in a first state, the conical teeth are engaged with the engagement tooth shape, and when the detection rotating member is in a second state, the separation portion is located at the engagement position between the engagement surface and the conical teeth to disengage the detection rotating member from the intermediate transmission shaft.

[0030] In a preferred embodiment of the present invention, an elastic member is further included, wherein the elastic member has a fixed portion fixed relative to the housing and an acting portion extending toward the detection rotating member, and the detection rotating member further has a third portion staggered from the first portion and the second portion in the direction of the first rotation axis, and the third portion has a first recessed portion circumferentially arranged around the first rotation axis.

[0031] When the detection rotatable member is in the second state, the acting portion of the elastic member abuts against the first recessed portion, so that the detection rotatable member is maintained in the second state.

[0032] In a preferred embodiment of the present invention, the housing includes a base fixed relative to the second side wall, and the detection rotating member and the detection information transmission member are rotatably disposed on the base and are disposed along the second rotation axis direction;

[0057] The following will describe the implementation methods of the present invention in detail in combination with the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that these specific descriptions are only for ordinary technicians in this field to understand the present invention more easily and clearly, rather than a restrictive interpretation of the present invention; for example, the first and second mentioned in the embodiments of the present invention do not constitute a limitation thereto, but are only for expressing the serial numbers of multiple identical or similar devices and mechanisms. Ordinary technicians in this field can also readjust these serial numbers for the convenience of expression or in the process of arranging technical solutions; and alternative solutions are described for some mechanisms in different embodiments, and these alternatives can also be applied to other identical or similar devices and mechanisms; and as long as there is no conflict, the various embodiments in the present invention and the various features in each embodiment can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0058] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments.

[0059] First, an image forming apparatus provided by an embodiment of the present invention is described.

[0060] like Figure 1 As shown, an image forming device includes a device body 100 and a paper tray 110, a paper feeding assembly 120, a conveying assembly 130, a developing assembly 140, a scanning assembly 150, a transfer assembly 160, a fixing assembly 170 and a paper discharge assembly 180 arranged on the device body 100. The paper tray 110 is used to store stacked recording media, which can be materials that can be recorded, such as paper. The paper tray 110 can be detached from the device body 100 by pulling out to replenish the recording media. The paper feeding assembly 120 is used to feed the recording media on the paper tray 110 into the input container of the device body 100 one sheet at a time. The feeding path includes a paper feeding roller, which abuts against the top layer of the stacked recording medium and pushes the recording medium from top to bottom. The conveying component 130 enables the recording medium fed by the paper feeding component 120 to move in the conveying path. The transfer component 160 is used to transfer the printed image to the recording medium in the conveying path after receiving the printed image from the developing component 140, and the recording medium with the printed image is further transported to the fixing component 170 and heated, so that the printed image on the recording medium is fixed on the recording medium, and then discharged to the outside of the paper discharge port by the paper discharge roller on the paper discharge component 180 and falls into the paper discharge tray outside the device body 100.

[0061] The image forming device is completed by the scanning assembly 150, the developing assembly 140 and the transfer assembly 160 when printing an image. Specifically, the scanning assembly 150 includes a light generator and a light transmission member composed of a plurality of optical elements. After the light generator emits scanning light to the light transmission member, the scanning light is deflected by the deflector of the rotator on the light transmission member and then enters the remaining optical elements of the light transmission member and is transmitted to the developing assembly 140. The developing assembly 140 includes at least one toner cartridge, and the toner cartridge has a photosensitive member and a developing roller 310 inside. The surface of the photosensitive member is made of a photosensitive material and can carry a certain charge, and charge conversion occurs after receiving the scanning light, that is, after the scanning assembly 150 transmits the scanning light to the photosensitive member of the toner cartridge, an electrostatic latent image is formed on the photosensitive member, and the photosensitive member receives the toner delivered from the developing roller 310 during the subsequent rotation process to form an image on its surface. The transfer assembly 160 is used to receive the image of the photosensitive member and transfer the image to the recording medium. In the present embodiment, the transfer assembly 160 includes a transfer belt and a secondary transfer roller. The transfer belt is located on the downstream side of the developing roller 310 in the rotation direction of the photosensitive member. In the process of contacting with the photosensitive member, the formed image is transferred to the transfer belt at the contact position, wherein the transfer belt can contact with the photosensitive members of multiple colorant boxes, thereby being able to carry multiple colors. The secondary transfer roller is arranged on the downstream side of each photosensitive member in the moving direction of the rotating belt. When the recording medium is transmitted to the position of the secondary transfer roller, the secondary transfer roller transfers the image to the recording medium.

[0062] The toner cartridge in the embodiment of the present invention is described in detail below.

[0063] See also Figures 2 to 5The toner cartridge includes a shell 200, a developing roller 310 and a stirring member 320. The shell 200 is used to wrap the developing roller 310 and the stirring member 320, and has a middle wall 210 and a first side wall 220 and a second side wall 230 located at both ends of the middle wall 210. A storage chamber 240 for storing toner is formed inside. In this embodiment, the first side wall 220 and the second side wall 230 are arranged opposite to each other and connected to the middle wall 210. The developing roller 310 is rotatably arranged in the shell 200, and its two ends extend into the first side wall 220 and the second side wall 230 respectively, and are located on the toner outlet of the storage chamber 240, and are used to transport the toner to the outside of the toner outlet. The stirring member 320 is rotatably arranged inside the storage chamber 240, and has a stirring blade thereon. When the stirring member 320 rotates, the stirring blade contacts the toner in the storage chamber 240 and pushes the toner to the toner outlet position. In this embodiment, the photosensitive member is arranged on the outside of the housing 200, the toner box is composed of a detachable box assembly and a photosensitive assembly, the housing 200, the developing roller 310 and the stirring member 320 are arranged on the box assembly, the photosensitive assembly includes a housing and a photosensitive member and a charging member rotatably arranged on the housing, the photosensitive member is located near the toner outlet and contacts the outer surface of the developing roller 310, and the developing roller 310 transports the toner to the photosensitive surface of the photosensitive member during the relative rotation of the photosensitive member and the developing roller 310. The charging member is used to lay an electric charge on the photosensitive surface of the photosensitive member, and the electric charge on the photosensitive surface changes polarity after being scanned by the scanning light to form an electrostatic latent image on the photosensitive surface. Of course, in the toner box, the photosensitive member and the charging member can also be arranged on the housing 200 to form an integrated structure, which is not limited here.

[0064] Furthermore, the colorant box also includes a powder feeding roller 330, which is rotatably arranged in the storage chamber 240 and located between the stirring member 320 and the developing roller 310. After the colorant box is installed on the device body 100 of the image forming device and is in use, the powder feeding roller 330 is located at the bottom of the storage chamber 240, and the developing roller 310 is arranged at the upper side of the powder feeding roller 330 and contacts the surface of the powder feeding roller 330. When the colorant is pushed by the stirring member 320 near the colorant outlet, the powder feeding roller 330 pushes the colorant located at the bottom of the storage chamber 240 to the developing roller 310, so as to avoid insufficient transportation of the colorant in the storage chamber 240 and cause excessive residue.

[0065] Among them, the colorant box also includes a driving gear 600 and a transmission gear set 700. The driving gear 600 is used to receive the driving force from the outside, that is, the device body 100 of the image forming device, and is arranged on the first side wall 220 of the shell 200. It has a power receiving part 610 at the end away from the first side wall 220. The power receiving part 610 has a coupling groove 611 which is concave in the axial direction. The coupling groove 611 is arranged with a docking part 612 which protrudes radially inward at a circumferential position. The device body 100 has a driving shaft engaged with the driving gear 600. In the process of the driving shaft driving the driving gear 600, the driving shaft extends into the coupling groove 611 and cooperates with the docking part 612 in a concave-convex manner, so that the driving force is transmitted to the driving gear 600 when the driving shaft rotates.

[0066] The transmission gear set 700 includes a first gear 710 for driving the developing roller 310, a second gear 720 for driving the stirring member 320, and a third gear 730 for driving the powder feeding roller 330. The first gear 710, the second gear 720, and the third gear 730 are all located on the first side wall 220. The driving gear 600 has a first gear portion 613 and a second gear portion 614 in its own axial direction. The first gear portion 613 is used to mesh with the first gear 710, and the second gear portion 614 is used to mesh with the second gear portion 614. The driving force is transmitted to the developing roller 310 and the powder feeding roller 330 by direct meshing, reducing the transmission error caused by the transmission chain, so as to be consistent with the control timing of the external image forming device. The second gear 720 is meshed with the driving gear 600 through the intermediate gear 750, which is adapted to the corresponding distance between the stirring member 320 and the powder feeding roller 330 and the developing roller 310 assembly. In addition, in this embodiment, the first gear portion 613 and the second gear portion 614 are helical tooth structures with opposite rotation directions. During the process of meshing with the first gear 710 and the third gear 730 respectively, not only can the meshing accuracy of the driving gear 600 with the first gear 710 and the third gear 730 be improved, and the transmission efficiency be improved, but also the driving gear 600 can be ensured to be subjected to uniform force, thereby increasing the service life of the driving gear 600.

[0067] See also Figures 3 to 7The colorant box also includes a detection rotating member 500 and an intermediate transmission shaft 400. The detection rotating member 500 is arranged on the shell 200 and can rotate on the shell 200. It is located closer to the second side wall 230 than the first side wall 220, and away from the transmission system formed by the driving gear 600 and the transmission gear set 700 in the first side wall 220, so as to avoid excessive integration on the first side wall 220. The intermediate transmission shaft 400 has a first end 410 and a second end 420. The first end 410 is inserted into the first side wall 220 to mesh with one of the gears in the transmission gear set 700. Specifically, in this embodiment, the gear is the intermediate gear 750, so that the intermediate transmission shaft 400 can receive the drive from the transmission gear set 700 and rotate. The second end 420 is arranged on the shell 200 at a position closer to the second side wall 230 to cooperate with the detection rotating member 500. The detection rotating member 500 rotates under the drive of the intermediate transmission shaft 400, and its rotation action can transmit detection information to the detection component of the image forming device.

[0068] Among them, the detection rotating member 500 rotates around the first rotation axis on the housing 200, and the intermediate transmission shaft 400 rotates around the second rotation axis on the housing 200, the first rotation axis is perpendicular to the second rotation axis, and the second rotation axis is parallel to the rotation axis of the driving gear 600. In such a setting, the axial direction of the intermediate transmission shaft 400 is the same as the length direction of the housing 200, and is parallel to the developing roller 310, the stirring member 320 and the powder feeding roller 330, and the detection rotating member 500 is arranged perpendicularly relative to the length direction of the housing 200. It should be noted that the detection rotating member 500 needs to cooperate with the external toggle component. When the circumferential dimension of the detection rotating member 500 is set too small, the toggle distance of the toggle component will be too small or it will be difficult to cooperate with the toggle component, so that the detection effect cannot be achieved. In the prior art, the detection rotating member 500 is set on the first side wall 220 or the second side wall 230, which will occupy a large amount of space on the side wall, so that the area of ​​the toner box perpendicular to the length direction cannot be effectively suppressed.

[0069] by Figures 3 to 7In the embodiment shown in the figure, the X direction is the direction of the second rotation axis, the Z direction is the direction of the first rotation axis, and the Y direction is perpendicular to the X direction and the Z direction. When the detection rotating member 500 is arranged in a manner that the circumferential surface is parallel to the outer surface of the first side wall 220, when the first side wall 220 is observed from the X direction, the driving gear 600, the first gear 710, the second gear 720, the intermediate gear 750 and the third gear 730 are arranged at the side position. Therefore, if the detection rotating member 500 is arranged on the first side wall 220, it will continue to occupy the side wall perpendicular to the X direction. The area in the X direction increases, and if it is set on the second side wall 230, its larger circumferential size will also affect the layout area of ​​each component on the second side wall 230, and the axial direction of the detection rotating member 500 needs to be set to be consistent with the X direction. At this time, the activity range affected by the rotation of the detection rotating member 500 is limited to the direction parallel to the second side wall 230, and it is necessary to arrange a toggle component to convert the activity in this direction into an action that can be detected by the detection component on the device body 100, thereby extending the size of the colorant box in the X direction.

[0070] Therefore, the first rotation axis of the detection rotating member 500 is set to be perpendicular to the second rotation axis, so that the detection rotating member 500 is arranged in the shell 200 relatively perpendicular to the middle wall 210, thereby freeing up layout space for the first side wall 220 and the second side wall 230, and will not affect the transmission accuracy of the gear components on the first side wall 220 and the second side wall 230.

[0071] In addition, the detection rotating member 500 can also be set to be located on the second side wall 230 on the shell 200, and the second end 420 of the intermediate transmission shaft 400 is located at the position of the second side wall 230. At this time, the rotational movement of the detection rotating member 500 around the first rotation axis is converted into a movement relative to the direction of the second rotation axis so as to be detected by the detection component.

[0072] In one embodiment, when the colorant box is installed in the image forming device and the image forming device is in use, the intermediate transmission shaft 400 is located above the stirring member 320. In this position, the colorant inside the storage chamber 240 is concentrated at the bottom of the storage chamber 240 due to gravity, and the thickness of the internal colorant gradually decreases as the colorant is consumed. Therefore, no matter whether the intermediate transmission shaft 400 is set inside the storage chamber 240 or outside the storage chamber 240, it will not affect the powder supply operation inside the colorant box.

[0073] Specific reference Figure 5When the image forming device is placed along the Z-axis direction as the height direction, the height of the intermediate transmission shaft 400 in the Z-direction is higher than the height of the stirring member 320 in the Z-direction, that is, it is located above the stirring member 320. At this time, the toner in the storage chamber 240 is deposited in the downward direction along the Z-direction. The intermediate transmission shaft 400 does not affect the deposition process. In addition, during the stirring process of the stirring member 320, since there is no toner deposition when the stirring blade passes through the intermediate transmission shaft 400 or passes through the position of the intermediate transmission shaft 400, it will not affect the stirring effect of the toner, thereby improving the space utilization rate inside the toner box. The detection rotating member 500 is located on the side of the intermediate transmission shaft 400 away from the storage chamber 240. Figure 5 It is shown as being located above the intermediate transmission shaft 400 in the Z direction, thereby not further compressing the storage space in the storage cavity 240 toward the storage cavity 240, making the overall layout more reasonable.

[0074] Furthermore, the intermediate transmission shaft 400 is separated from the receiving chamber 240 by the intermediate wall 210. The intermediate wall 210 is provided with a placement groove 250 which is concave toward the receiving chamber 240 and is arranged along the length direction. Figure 5 The intermediate transmission shaft 400 is located at the upper position of the receiving groove in the Z direction, and the intermediate transmission shaft 400 is prevented from being exposed to the outside of the shell 200 of the colorant box while ensuring the separation between the intermediate transmission shaft 400 and the receiving cavity 240.

[0075] In another embodiment, the detection rotating member 500 includes at least a first state and a second state, wherein in the first state, the detection rotating member 500 is engaged with the intermediate transmission shaft 400 and can receive the driving force from the intermediate transmission shaft 400 to perform a rotation action, for example, Figure 5 In the first state, the first end 410 of the intermediate transmission shaft 400 has a fourth gear 740 meshing with the intermediate gear 750. After the driving gear 600 drives the intermediate gear 750 to rotate, the intermediate gear 750 drives the fourth gear 740 and then drives the intermediate transmission shaft 400 to rotate. In the first state, the second end 420 of the intermediate transmission shaft 400 is engaged with the detection rotating member 500 and converts the rotational motion along the second rotation axis into the motion of the detection rotating member 500 along the first rotation axis.

[0076] In the second state, the detection rotating member 500 is separated from the intermediate transmission shaft 400, and the intermediate transmission shaft 400 can no longer transmit the driving force to the detection rotating member 500 and is in an idling state. Therefore, when the detection rotating member 500 is in the first state and is driven by the intermediate transmission shaft 400 to rotate by a preset angle, the detection rotating member 500 switches from the first state to the second state. Figure 7When the detection rotating member 500 is located at the first position, the detection rotating member 500 is in the first state, the detection rotating member 500 is combined with the intermediate transmission shaft 400 and is driven to rotate along the W direction, and the disengagement position of the detection rotating member 500 is set at the downstream position of the rotation in the W direction. When the rotation continues, the disengagement position will move to the original engagement position between the detection rotating member 500 and the intermediate transmission shaft 400. At this time, the detection rotating member 500 no longer receives the driving force from the intermediate transmission shaft 400 and is in the second state.

[0077] Among them, see Figure 6 The toner cartridge further comprises a detection information transmission member 800, which is disposed on the housing 200 and has an information transmission portion 810 protruding from the second side wall 230. The rotation of the detection information transmission member 800 forms a third rotation axis, which is perpendicular to the second rotation axis and parallel to the first rotation axis. The detection rotating member 500 comprises a first portion 510 and a second portion 520 distributed along the first rotation axis. The first portion 510 has a joint surface 511 engaged with the second end portion 420 of the intermediate transmission shaft 400. The second portion 520 comprises a termination portion 521 and at least one counting portion 522 arranged circumferentially around the first rotation axis, wherein the termination portion 521 is located downstream of the last counting portion 522 in the rotation direction of the detection rotating member 500. The detection information transmission member 800 has a contact portion 820 for contacting each counting portion 522 and the termination portion 521. When the detection rotating member 500 is in the initial position of the first position, refer to Fig. 9 , the first part 510 of this embodiment has two counting parts 522, each counting part 522 is located at an upstream position of the contact position between the contact part 820 and the first part 510; when the detection rotating member 500 rotates along the W direction and is in the second position, refer to Fig.10 , the first counting part 522a starts to contact the contact part 820 and pushes the detection information transmission member 800 to rotate along the U direction through the contact part 820. When the first counting part 522a leaves the contact part 820, the detection information transmission member 800 is reset and rotates in the opposite direction of U. Thus, the first counting part 522a causes the detection information transmission member 800 to swing once. When the detection rotating member 500 continues to rotate and is in the third position, refer to Fig.11 , the second counting part 522b starts to contact the contact part 820 and pushes the detection information transmission member 800 to rotate again along the U direction through the contact part 820, so that the detection information transmission member 800 swings again; then the detection rotating member 500 continues to rotate to the fourth position, see Figure 8The stop portion 521 contacts the contact portion 820 and causes the detection information transmission member 800 to rotate along the U direction. At this time, the detection rotating member 500 is disengaged from the intermediate transmission shaft 400 and is in the second state, so that the stop portion 521 causes the detection information transmission member 800 to stay in the position after the swing.

[0078] It should be noted that each time the counting part 522 contacts the contact part 820, the detection information transmission part 800 will swing once during each contact process, swinging from the first posture to the second posture, and the information transmission part 810 will move accordingly at the protruding position of the second side wall 230 during each swing process, so as to be detected by the detection component on the device body 100, and after the counting part 522 is out of contact, the counting part 522 is reset from the second posture to the first posture, and has the potential to rotate from the first posture to the second posture direction (i.e., the opposite direction of the U direction), and the potential can be provided by the reset elastic member connected to the detection information transmission part 800, or it can be realized by friction or the corresponding components on the device body 100, without specific limitation. In addition, the number of the counting part 522 can be set to one or more according to actual conditions, all within the scope of implementation of the embodiment of the present invention.

[0079] Therefore, see further Figures 8 to 11 , there is a counting gap 523 between adjacent counting parts 522 and between the counting part 522 and the termination part 521, so that the contact part 820 resets and rotates in the counting gap 523 after breaking away from the contact with the corresponding counting part 522. Specifically, when the detection rotating member 500 is in the first state, each time the counting part 522 contacts the contact part 820, the detection information transmission member 800 overcomes the potential to move from the second posture to the first posture (i.e., along the U direction), and when the contact part 820 breaks away from the contact with the corresponding counting part 522 and enters the counting gap 523, the potential is accumulated to make the detection rotating member 500 move from the first posture to the second posture (i.e., in the opposite direction of the U direction). When the detection rotating member 500 is in the initial position of the first state, the contact part 820 enters the preparation gap in front of the first counting part 522a, and the detection information transmission member 800 is in the first posture; when the detection rotating member 500 is in the second state, the detection information transmission member 800 is maintained in the second posture by the termination part 521, and this state can be sensed by an external detection component.

[0080] In one detection implementation, the detection component senses the swing position of the information transmission portion 810. When it is sensed that the information transmission portion 810 is located at the first placement position when the detection information transmission member 800 is in the first posture, the detection component knows that the colorant box may be a new colorant box, and thus performs the next step of sensing, driving the driving gear 600 to rotate. The detection rotating member 500 drives the detection information transmission member 800 to swing as the driving gear 600 rotates. Each counting portion 522 causes the detection information transmission member 800 to swing once. The detection component determines whether the preset conditions are met based on the swing of the detection information transmission member 800. If so, the colorant box is determined to be an adaptable new colorant box and corresponding program control is executed to initialize the colorant box information, and the detection information transmission member 800 is kept in the second posture in the termination portion 521. After the detection information transmission member 800 in the second posture is sensed by the detection component, it indicates that the colorant box is a used or in-use colorant box.

[0081] See also Figure 6 The intermediate transmission shaft 400 has a conical tooth 430 on the second end 420, and the conical tooth 430 changes the direction of the rotation axis, wherein the engagement surface 511 includes an engagement tooth shape 511a and a separation portion 511b arranged circumferentially around the first rotation axis, and when the detection rotating member 500 is in the first state, the conical tooth 430 meshes with the engagement tooth shape 511a to transmit the driving force, and when the detection rotating member 500 is in the second state, the separation portion 511b is located at the combination position of the engagement surface 511 and the conical tooth 430, so that the detection rotating member 500 is disengaged from the intermediate transmission shaft 400. Of course, other structures for achieving transmission and disengagement can also be used, which are not limited here.

[0082] Furthermore, the toner cartridge further includes an elastic member 540 for maintaining the detection rotating member 500 in the second state, wherein the elastic member 540 includes a fixing portion 542 fixed relative to the housing 200 and an acting portion 541 extending toward the detection rotating member 500, and the detection rotating member 500 also includes a third portion 530 staggered from the first portion 510 and the second portion 520 in the direction of the first rotation axis, see Figure 3 The third part 530 has a first recess 531 arranged circumferentially around the first rotation axis, and the first recess 531 is formed by a first protrusion 532 and a second protrusion 533 arranged circumferentially. When the detection rotating member 500 is in the second state, the action portion 541 of the elastic member 540 abuts against the first recess 531, thereby maintaining the detection rotating member 500 in the second state.

[0083] See also Figure 6 and Figure 7The housing 200 further includes a base 900 fixed relative to the second side wall 230. The base 900 is detachably arranged on the housing 200 by means of screw connection or snap connection, and its end face is perpendicular to the first rotation axis and extends along the second rotation axis. The detection rotating member 500 and the detection information transmission member 800 are both rotatably arranged on the base 900 and arranged along the second rotation axis. In this embodiment, by additionally arranging the base 900 for connecting the detection rotating member 500 and the detection information transmission member 800, a stable assembly environment can be provided for the two components, which is convenient for assembly, and at the same time, the difficulty of opening the mold of the housing 200 is reduced, which is conducive to improving the overall assembly compactness of the toner cartridge.

[0084] Among them, the base 900 has a spring column 910 for installing the fixing part 542 of the elastic member 540 and a clamping part 920 located on the opposite side of the detection rotating member 500 relative to the spring column 910. The clamping part 920 protrudes from the end face along the first rotation direction. The elastic member 540 has a relative part 543 connected to the fixing part 542 and abutting on the clamping part 920. The relative part 543 provides the acting part 541 with a potential accumulation effect caused by elastic deformation when the position is fixed, so that the acting part 541 abuts against the first recess 531.

[0085] Finally, it should be noted that the above description is only the best embodiment of the present invention and does not limit the present invention in any form. Any technician familiar with the art can make many possible changes and simple replacements to the technical solution of the present invention by using the above disclosed practices and technical contents without departing from the scope of the technical solution of the present invention, which all belong to the scope of protection of the technical solution of the present invention.
