Description

Technical Field

[0001] This invention relates to the field of printing consumables, and more specifically, to a toner cartridge and its installation method, and an imaging device. Background Technology

[0002] Electro-imaging equipment is widely used, including printers and copiers. Printers and copiers typically require toner cartridges to supply consumables for operation.

[0003] An imaging device has a toner cartridge compartment with a triggered component on its upper surface that retracts into the device upon activation. A mechanical switch is located near the drive head within the toner cartridge compartment. When closed, the mechanical switch blocks the drive head, preventing the toner cartridge from being installed. When open, the drive head is exposed within the compartment, allowing installation. This mechanical switch is linked to the triggered component; when activated, the switch opens, allowing the toner cartridge to be installed. When unactivated, the switch closes, preventing installation.

[0004] like Figure 1 As shown, the upper surface of the toner cartridge body 101 of the existing imaging device is provided with two upwardly protruding ribs 102 that serve as triggering components. These ribs 102 are integrally formed with the cartridge body 101. During the process of installing the toner cartridge into the cartridge compartment of the imaging device, the ribs 102 push against the triggered component in the imaging device to trigger the triggered component, open the mechanical switch, and allow the toner cartridge to be normally installed into the cartridge compartment for printing.

[0005] However, in this type of imaging equipment, different countries or regions have different models of the same imaging equipment, and the arrangement of the triggered component on the upper surface of the cartridge compartment along the left-right direction also varies. This makes the aforementioned toner cartridges incompatible with these imaging devices. Since the entire toner cartridge is structurally identical except for the arrangement of the protrusion 102 used to trigger the triggered component, manufacturers need to prepare molds for toner cartridges with corresponding protrusions 102 for different countries or regions, significantly increasing production costs. Furthermore, consumers can only purchase toner cartridges with the protrusion 102 in a specific position; if the wrong cartridge is purchased, it cannot be installed or used. Because the difference is minor, it is difficult for ordinary consumers to identify, resulting in poor versatility and a poor customer experience for the existing toner cartridges. Summary of the Invention

[0006] The first objective of this invention is to provide a powder box that improves versatility.

[0007] A second objective of the present invention is to provide an imaging device having the aforementioned powder cartridge.

[0008] A third objective of this invention is to provide a method for installing the aforementioned powder box.

[0009] A fourth objective of this invention is to provide another method for loading the aforementioned powder cartridge.

[0010] To achieve the aforementioned first objective, the present invention provides a powder cartridge, comprising a cartridge body and a rotating component. The rotating component is rotatably supported between the two end walls of the cartridge body. A driving head is provided at one end of the cartridge body, which can drive the rotating component to rotate. A trigger part is also provided on the cartridge body, protruding outward from the outer surface of the cartridge body. The powder cartridge also includes a trigger member. The top wall of the cartridge body has two or more mounting slots, the number of mounting slots being greater than or equal to the number of trigger members. One trigger member is engaged in one of the mounting slots. During the powder cartridge assembly process, at least one trigger member is held in the extended position, and the trigger part is disposed on the trigger member held in the extended position, with the trigger part located outside the mounting slot.

[0011] As can be seen from the above solution, by separating the trigger component from the cartridge body and then snapping the trigger component into the corresponding mounting slot, manufacturers no longer need to use different molds for production based on the different imaging equipment models and the different positions of the triggered components in each sales region. Furthermore, the trigger component and cartridge body can be produced uniformly, and then the trigger component can be installed in the corresponding mounting slot according to the position of the triggered component in the imaging equipment model of each sales region before being sold to the corresponding region. This allows for the use of a single mold to produce different models of toner cartridges for various regions, thus reducing mold costs. Alternatively, trigger components that can automatically switch positions can be installed in each mounting slot. Since the guide slots for the triggered components are located in different sales regions on imaging devices, during the toner cartridge installation process, trigger components that are not in contact with the guide slots will automatically switch to the retracted position under the force of the top wall of the imaging device. The trigger components that remain in the extended position will trigger the triggered components inside the imaging device. In this way, the toner cartridge can be used with imaging devices in various sales regions, thereby improving the toner cartridge's versatility, reducing the toner cartridge's production cost, and for consumers, there is no need to distinguish between different versions in different countries and regions; they only need to use the toner cartridge that is compatible with the corresponding printer, thus improving the customer experience.

[0012] A preferred embodiment is that the side wall of the triggering member is provided with a snap-fit ​​portion, which protrudes from the corresponding side wall of the triggering member in a direction away from the side wall; the side wall of the mounting groove is provided with a movable groove, into which the snap-fit ​​portion extends; the snap-fit ​​portion is provided with a locking groove, and a buckle is provided at the opening of the movable groove. In the installation direction of the toner cartridge, the buckle is located downstream of the locking groove, and the buckle and the locking groove are engaged in an upper limit fit in the installation direction of the toner cartridge to keep the triggering member in the extended position.

[0013] It can be seen that the limiting fit between the buckle and the slot in the installation direction of the toner cartridge enables the triggering component to remain stably in the extended position when no external force is applied.

[0014] A further embodiment is that both the trigger part and the mounting groove are located on the top wall of the housing, with the trigger part protruding outward from the top wall of the housing; the trigger member is slidably connected to the movable groove and can switch between an extended position and a retracted position; in the extended position, the maximum distance between the trigger part and the top wall of the housing is a first height value; in the retracted position, a portion of the trigger member is located outside the mounting groove, and the maximum distance between the exposed portion of the trigger member and the top wall of the housing is a second height value, where the first height value is greater than the second height value; or in the retracted position, the trigger member is hidden inside the mounting groove.

[0015] Therefore, by incorporating a trigger component that can switch between extended and retracted positions, the trigger component can automatically switch to the retracted position or remain in the extended position during toner cartridge installation, depending on the position of the guide groove for the triggered component on imaging equipment in different sales countries or regions. This improves the versatility of the toner cartridge. Furthermore, when the trigger component is in the retracted position, it can either protrude slightly outward from the top wall of the cartridge or be hidden within the mounting slot, as long as it does not interfere with the installation process.

[0016] A further option is to provide a force-receiving part at the downstream end of the triggering component. After receiving external force, the force-receiving part can drive the locking part to move away from the buckle until the buckle disengages from the slot, the locking part enters the movable slot, and drives the triggering component to move to the retracted position.

[0017] It can be seen that when the force-bearing part is subjected to force, it can drive the locking part to disengage from the buckle, thereby allowing the triggering component to retract under its own weight or external tension.

[0018] A further solution is to elastically connect the downstream end of the trigger component to the box body in the installation direction of the toner cartridge.

[0019] It can be seen that the elastic connection between the downstream end of the trigger component and the box body allows the trigger component to retract into the mounting groove under the action of elastic restoring force after the snap-fit ​​part disengages from the buckle.

[0020] A further embodiment includes an elastic element in the powder box, with a limiting part provided at the downstream end of the box body near the triggering member, and the two ends of the elastic element being connected to the triggering member and the limiting part, respectively.

[0021] Therefore, by means of the elastic element, after the snap-fit ​​part is disengaged from the buckle, the elastic element can provide a pulling force to the triggering component, causing the triggering component to retract into the mounting groove.

[0022] A further embodiment is that the triggering component also includes a main body and a deformation part arranged at an obtuse angle; the deformation part is located at the downstream end of the triggering component, the triggering part is located on the main body of the corresponding triggering component, and the force-bearing part is located at the end of the deformation part near the main body; the box body is provided with a limiting part at the downstream end near the triggering component, and the end of the deformation part away from the main body is fitted onto the limiting part.

[0023] Therefore, when the snap-fit ​​part is not disengaged from the buckle, under the constraint of the limiting part on the deformable part and the force on the force-bearing part, the deformable part can undergo elastic deformation. After the snap-fit ​​part is disengaged from the buckle, the elastic restoring force of the deformable part can provide a pulling force to the main body, causing the triggering member to retract into the mounting groove.

[0024] A further option is to provide an elastic part at the upstream end of the triggering member, wherein the elastic part on the triggering member in the extended position abuts against the side wall of the mounting groove, and the elastic part on the triggering member in the retracted position separates from the side wall of the mounting groove.

[0025] Therefore, when in the extended position, the elastic part provides support, and when in the retracted position, the elastic part of the triggering component separates from the side wall of the mounting groove, so that the triggering component remains in the retracted position to avoid interference during the powder box loading process.

[0026] A further embodiment is that the elastic part extends in an arc shape, with the fixed end of the elastic part connected to the bottom wall of the triggering member, and the free end of the elastic part on the triggering member in the extended position abutting against the side wall of the mounting groove near the upstream end of the triggering member.

[0027] It can be seen that the limiting effect of the buckle and the slot is to limit the position of the triggering component. At the same time, the free end of the elastic part abuts against the mounting groove and supports the triggering component on the front side. Thus, with the cooperation of the elastic part, the slot and the buckle, the triggering component can be stably supported in the extended position.

[0028] A preferred embodiment is that, in the extended position, the interference between the trigger member and the mounting groove is S1, and in the retracted position, the interference between the trigger member and the mounting groove is S2, where S1 < S2.

[0029] A further option is to have S1 in the range of 0.01 mm to 0.04 mm and S2 in the range of 0.05 mm to 0.15 mm.

[0030] Therefore, by controlling the magnitude of the frictional force that hinders sliding between the trigger component and the mounting groove through the interference fit, the trigger component can switch from the extended position to the retracted position more effectively, and under the action of friction, the trigger component can be better maintained in the retracted position. At the same time, the trigger component can switch between the extended position during triggering and the retracted position when not triggering, which improves the versatility of the powder box, simplifies the structure of the trigger assembly, and saves production costs.

[0031] A preferred embodiment is that the triggering component is also provided with a stop wall, and a stop mating wall is provided at the top of the mounting groove. When the triggering component moves to the retracted position, the stop wall and the stop mating wall engage in a limiting fit.

[0032] Therefore, it can be seen that the limiting fit between the stop wall and the stop mating wall on the box body can prevent the triggering component from falling.

[0033] A preferred embodiment is that the triggering component is fixed within the mounting slot.

[0034] Therefore, fixing the triggering component in the mounting slot can improve the stability of the connection between the triggering component and the housing.

[0035] A further embodiment is that both the trigger part and the mounting groove are located on the top wall of the housing, with the trigger part protruding outward from the top wall of the housing; at least one trigger member is held in the retracted position, the maximum distance between the trigger part on the trigger member held in the extended position and the top wall of the housing is a third height value, and the maximum distance between the top of the trigger member in the retracted position and the top wall of the housing is a fourth height value, with the third height value being greater than the fourth height value.

[0036] Therefore, it can be seen that triggering components that do not contact the triggered component can also be directly installed in the retracted position. These triggering components can be used as spare parts. When the triggering component that contacts the triggered component is damaged, these spare parts can be used to replace it, thereby extending the service life of the toner cartridge.

[0037] A further design is to provide a slot and a limiting hook for the triggering component. The inner wall of the slot is provided with a cantilever, and the locking part is located at the free end of the cantilever. The end of the buckle away from the locking part is provided with a fastening part, and the limiting hook is located on the side wall of the triggering component and fastens to the fastening part on the downstream side of the fastening part.

[0038] It can be seen that the limiting cooperation between the limiting hook and the fastening part, as well as the limiting cooperation between the buckle and the slot, can ensure a stable connection between the triggering component and the box.

[0039] A further embodiment is that the triggering component is also provided with a limiting protrusion, and a relief groove is provided on the side of the movable groove opposite to the buckle. The limiting protrusion protrudes from the corresponding side wall of the triggering component in a direction away from the side wall. The limiting protrusion is located in the relief groove, and the top wall of the limiting protrusion abuts against the top wall of the relief groove. The fixed end of the cantilever is connected to the side wall of the slot away from the limiting protrusion, and the free end of the cantilever extends toward the limiting protrusion and forms a gap with the limiting protrusion.

[0040] It can be seen that by setting the limiting protrusion and cooperating with the buckle and the slot, the limiting cooperation between the trigger component and the box body is achieved and the connection is stable, preventing the trigger component from falling out of the mounting slot.

[0041] A preferred embodiment is that the slot is provided with a first limiting wall and a second limiting wall set at an acute angle, with the second limiting wall inclined upward; the buckle is provided with a first mating wall and a second mating wall set at an acute angle, with the second mating wall inclined downward; the first mating wall contacts and slides with the first limiting wall, and the second mating wall abuts against the second limiting wall.

[0042] It can be seen that the cooperation between the first mating wall and the first limiting wall, as well as the cooperation between the second mating wall and the second limiting wall, ensures that the buckle can be stably engaged in the slot. At the same time, the sliding cooperation between the first mating wall and the first limiting wall ensures that when the triggering component is subjected to external force, the first limiting wall can slide along the first mating wall, thereby guiding the triggering component and ensuring that the triggering component can smoothly enter the mounting slot.

[0043] A further embodiment includes a guide wall at the bottom of the latching part. The guide wall comprises a first straight section, a sloped section, and a second straight section connected sequentially along the extension direction of the latching part. The first straight section is parallel to the second straight section, and the sloped section is set at an obtuse angle to the first straight section. The side of the second straight section away from the sloped section is connected to the second limiting wall. The buckle is also provided with a guide slope, which is connected to the side of the first mating wall away from the second mating wall and intersects with the first mating wall. The guide slope is inclined upwards and can slide with the guide wall, guiding the latching part to the position where the latching part is in a limiting engagement with the buckle.

[0044] Therefore, when the trigger component is assembled onto the box, after the guide wall moves along the guide slope and the first mating wall, the snap-fit ​​enters the slot, thereby limiting the position of the trigger component.

[0045] A further option is to provide a guide arc surface for the snap-fit ​​part. The guide arc surface is connected to the side of the first limiting wall away from the second limiting wall and bends in a direction away from the second limiting wall. The guide arc surface can slide and engage with the second mating wall.

[0046] As can be seen, after the buckle disengages from the slot, the guide arc surface slides into the second mating wall, thereby guiding the snap-fit ​​part into the mounting slot, and thus allowing the triggering component to smoothly enter the retracted position.

[0047] A preferred embodiment is that a clearance groove is provided on the side of the movable groove opposite to the buckle, and the end of the engaging part away from the buckle extends into the clearance groove, with the top wall of the engaging part abutting against the top wall of the clearance groove.

[0048] It can be seen that by limiting the fit between the clearance groove and the snap-fit ​​part, the front end of the triggering component is prevented from flipping upward and detaching from the mounting groove.

[0049] In a preferred embodiment, the powder cartridge includes a trigger module, which comprises a base and a trigger member, with a mounting slot located on the base, and the base being detachably and fixedly connected to the cartridge body.

[0050] Therefore, it can be seen that the trigger module can also be manufactured and assembled separately.

[0051] To achieve the second objective mentioned above, the present invention provides an imaging device, including the aforementioned toner cartridge and a device body. The device body has a cartridge compartment, and the toner cartridge is detachably installed in the cartridge compartment. A guide groove is formed on the top wall of the cartridge compartment, and a triggered component is disposed in the guide groove. A transmission head is disposed on the side wall of the cartridge compartment. The triggered component, which is kept in an extended state on the toner cartridge, can enter the guide groove and slide along the guide groove. During the sliding process, the triggering part of the triggered component can trigger the corresponding triggered component in the guide groove. After the triggered component is triggered, the transmission head extends out from the side wall of the cartridge compartment.

[0052] To achieve the third objective mentioned above, the present invention provides a method for installing a toner cartridge. The toner cartridge is detachably installed in the cartridge compartment of an imaging device. A guide groove is provided on the top wall of the cartridge compartment, and a triggered component is disposed in the guide groove. A transmission head is disposed on the side wall of the cartridge compartment. The toner cartridge is as described above. The installation method includes: the triggered component corresponding to the guide groove is held in an extended position, and the triggered component misaligned with the guide groove is held in a retracted position; or the toner cartridge is provided with a triggered component only at the position corresponding to the guide groove, and the triggered component is held in the extended position; as the toner cartridge moves into the cartridge compartment, the triggered component slides into the corresponding guide groove. During the sliding process, the triggering part of the triggered component can trigger the triggered component in the corresponding guide groove. After the triggered component is triggered, the transmission head extends from the side wall of the cartridge compartment.

[0053] To achieve the fourth objective mentioned above, the present invention provides a method for installing a toner cartridge. The toner cartridge is detachably installed in the cartridge compartment of an imaging device. A guide groove is provided on the top wall of the cartridge compartment, and a triggered component is disposed in the guide groove. A transmission head is disposed on the side wall of the cartridge compartment. The toner cartridge is as described above. The installation method includes: before installation, all triggered components are in the extended position; as the toner cartridge moves into the cartridge compartment, the triggered component located outside the guide groove is subjected to a force applied by the top wall of the cartridge compartment and switches from the extended position to the retracted position. The triggered component located in the guide groove remains in the extended position and slides in cooperation with the corresponding guide groove. During the sliding process, the triggering part of the triggered component can trigger the triggered component in the corresponding guide groove. After the triggered component is triggered, the transmission head extends from the side wall of the cartridge compartment. Attached Figure Description

[0080] Toner cartridge and its installation method, imaging equipment - first embodiment:

[0081] See Figure 2 and Figure 3 The imaging device of this embodiment includes a toner cartridge 10 and a device body 20. The device body 20 has a cartridge compartment 21, and the toner cartridge 10 is detachably installed in the cartridge compartment 21. A guide groove 22 is formed on the top wall of the cartridge compartment 21, and a triggered component 23 is disposed within the guide groove 22. A drive head (not shown) is disposed on the side wall of the cartridge compartment 21. The triggered component 12 (described in detail below), which is extended from the toner cartridge 10, can enter the guide groove 22 and slide along it. During the sliding process, the triggering part 121 of the triggered component 12 can trigger the corresponding triggered component 23 in the guide groove 22. After the triggered component 23 is triggered, the drive head extends from the side wall of the cartridge compartment 21 and engages with the drive head of the toner cartridge 10 to transmit driving force. In this embodiment, the triggered component is a touch switch.

[0082] The toner cartridge 10 includes a cartridge body 11, rotating components, six triggering members 12, and six elastic members. The rotating components are rotatably supported between the two end walls of the cartridge body 11. The rotating components include a developing roller, a toner feeding roller, a photosensitive drum 14, and a stirring frame, etc. One end of the cartridge body 11 is provided with a drive head (not shown) and a gear train (not shown). After receiving the driving force from the transmission head, the drive head drives each rotating component to rotate through the gear train. Preferably, the elastic members are tension springs 13.

[0083] See Figures 4 to 6 The top wall of the box body 11 has six mounting slots 111, which are spaced apart and arranged parallel to each other along the length of the box body 11. Each trigger member 12 corresponds to one of the mounting slots 111, that is, each trigger member 12 is engaged in one of the mounting slots 111. During the installation of the powder box 10, two of the trigger members 12 can be kept in the extended position, and the trigger members 12 kept in the extended position are provided with trigger parts 121, which are located outside the mounting slots 111 and protrude outward from the top wall of the box body 11.

[0084] The six triggering components 12 have identical structures and are arranged in parallel. Tension springs 13 are correspondingly positioned one-to-one with each triggering component 12, in the installation direction of the toner cartridge 10 (e.g., ...). Figure 3 In the direction indicated by the middle arrow X, the downstream end of the trigger member 12 is elastically connected to the box body 11 via a tension spring 13. The box body 11 is provided with six limiting parts 112 near the downstream end of the trigger member 12. The two ends of a tension spring 13 are respectively connected to a trigger member 12 and a corresponding limiting part 112.

[0085] Each trigger member 12 has a locking part 122 on two opposite sidewalls in the thickness direction of the trigger member 12. Each locking part 122 protrudes from the corresponding sidewall of the trigger member 12 in a direction away from the sidewall. The sidewall of the mounting groove 111 has two movable grooves 113. One locking part 122 extends into one movable groove 113. Each locking part 122 has a locking slot 123. Each movable groove 113 has a buckle 114 at the slot opening 1131. In the installation direction of the toner cartridge 10, the buckle 114 is located downstream of the corresponding locking slot 123. The buckle 114 and the corresponding locking slot 123 are engaged in the upper limit cooperation in the installation direction of the toner cartridge 10 to keep the trigger member 12 in the extended position.

[0086] The trigger member 12 is slidably connected to the movable groove 113, and the trigger member 12 can be in the extended position (e.g., Figure 8 The location of the triggering component at the cut point shown) and the retraction position (e.g.) Figure 9 The position of the trigger member 121 at the cutout shown is switched between the extended position and the retracted position. In the extended position, the maximum distance between the trigger part 121 and the top wall of the housing 11 is a first height value; in the retracted position, a portion of the trigger member 12 is located outside the corresponding mounting groove 111, and the maximum distance between the exposed portion of the trigger member 12 and the top wall of the housing 11 is a second height value, where the first height value is greater than the second height value. Alternatively, in other embodiments, in the retracted position, the trigger member 12 can also be completely hidden within the corresponding mounting groove 111.

[0087] The downstream end of the triggering member 12 is also provided with a force receiving part 124. After receiving external force, the force receiving part 124 can drive the locking part 122 to move away from the buckle 114 until the buckle 114 disengages from the slot 123, the locking part 122 enters the movable slot 113, and drives the triggering member 12 to move to the retracted position.

[0088] See Figures 7 to 12Each slot 123 is provided with a first limiting wall 125 and a second limiting wall 126 set at an acute angle. The second limiting wall 126 is inclined upward. Each buckle 114 is provided with a first mating wall 115 and a second mating wall 116 set at an acute angle. The second mating wall 116 is inclined downward. The first mating wall 115 on the buckle 114 contacts and slides with the first limiting wall 125 in the corresponding slot 123. The second mating wall 116 on the buckle 114 abuts against the second limiting wall 126 in the corresponding slot 123. The engagement of the first mating wall 115 with the first limiting wall 125 and the engagement of the second mating wall 116 with the second limiting wall 126 ensure that the buckle 114 can be stably engaged in the corresponding slot 123. At the same time, the sliding engagement of the first mating wall 115 with the first limiting wall 125 ensures that when the triggering member 12 is subjected to external force, the first limiting wall 125 can slide along the first mating wall 115 to guide the triggering member 12 and ensure that the triggering member 12 smoothly enters the mounting slot 111.

[0089] Each latching part 122 is further provided with a guide wall 127 at its bottom. The guide wall 127 includes a first straight section 1271, a sloped section 1272, and a second straight section 1273 connected sequentially along the extension direction of the latching part 122. The first straight section 1271 is parallel to the second straight section 1273. The sloped section 1272 is set at an obtuse angle to the first straight section 1271. The side of the second straight section 1273 away from the sloped section 1272 is connected to the second limiting wall 126. Each latch 114 is further provided with a guide slope 117. The guide slope 117 is connected to the side of the first mating wall 115 away from the second mating wall 116 and intersects with the first mating wall 115. The guide slope 117 is inclined upward and can slide with the guide wall 127, guiding the latching part 122 to the position where the latching part 122 is limited to the latch 114. When the trigger component 12 is assembled onto the housing 11, after the guide wall 127 moves along the guide slope 117 and the first mating wall 115, the buckle 114 enters the slot 123, thereby limiting the position of the trigger component 12.

[0090] Each snap-fit ​​portion 122 is also provided with a guide arc surface 128. The guide arc surface 128 is connected to the side of the corresponding first limiting wall 125 away from the second limiting wall 126 and bends away from the corresponding second limiting wall 126. The guide arc surface 128 can slide and engage with the second mating wall 116. After the buckle 114 disengages from the slot 123, the guide arc surface 128 slides and engages with the second mating wall 116, thereby guiding the snap-fit ​​portion 122 into the mounting groove 111, so that the trigger member 12 smoothly enters the retracted position.

[0091] A clearance groove 118 is provided on the side of the movable groove 113 opposite to the corresponding buckle 114. In the extended position, the end of the engaging part 122 away from the buckle 114 extends into the clearance groove 118, and the top wall of the engaging part 122 abuts against the top wall of the clearance groove 118. Through the limiting cooperation between the clearance groove 118 and the engaging part 122, the front end of the triggering member 12 is prevented from flipping upward and disengaging from the mounting groove 111.

[0092] Each triggering component 12 is also provided with a stop wall 129, and the top of the mounting groove 111 is provided with a stop mating wall 119. When the triggering component 12 moves to the retracted position, the stop wall 129 and the stop mating wall 119 are engaged in the depth direction of the mounting groove 111.

[0093] The method for installing the powder box 10 in this embodiment includes:

[0094] Before installation, all triggering components 12 are in the extended position, such as Figure 8 As shown, at this time, the latch 114 and the slot 123 cooperate to limit the movement, and the top wall of the latching part 122 abuts against the top wall of the relief groove 118. Under the limiting cooperation of the top wall of the relief groove 118, the latch 114 and the latching part 122, the triggering member 12 is stably held in the extended position. In the imaging device's cartridge compartment 21, there are two guide grooves 22, and each guide groove 22 is provided with a triggered member 23.

[0095] As the powder cartridge 10 moves into the cartridge compartment 21, the force-receiving part 124 of the trigger member 12 located outside the guide groove 22 of the cartridge compartment 21 interferes with the top wall of the cartridge compartment 21. Consequently, the force-receiving part 124 of the trigger member 12 is subjected to a force F exerted by the top wall of the cartridge compartment 21. The first limiting wall 125 of the locking part 122 slides along the first mating wall 115 of the buckle 114 toward the corresponding relief groove 118. During this process, the tension spring 13 undergoes elastic deformation under tensile force. After the buckle 114 separates from the first limiting wall 125, under the guidance of the guide arc surface 128, the second mating wall 116, and the elastic restoring force of the tension spring 13, the locking part 122 moves from the opening 1131 of the movable groove 113 to the bottom of the movable groove 113, and the trigger member 12 retracts to the position shown in the image. Figure 10 The retracted position is shown.

[0096] Meanwhile, the triggering member 12 on the powder box 10, which can slide and engage with the guide groove 22 of the box compartment 21, will not interfere with the top wall of the box compartment 21 due to the setting of the guide groove 22, and can therefore remain in the extended position. During the sliding process, the triggering part 121 of the triggering member 12 can trigger the triggered member 23 in the corresponding guide groove 22. After the triggered member 23 is triggered, the transmission head extends from the side wall of the box compartment 21 to complete the installation of the powder box 10.

[0097] Alternatively, before installation, all or part of the triggering components 12 that do not slide with the guide groove 22 can be manually pushed to the retracted position. That is, before the toner cartridge 10 is installed, all or part of the triggering components 12 that are misaligned with the guide groove 22 are kept in the retracted position. Or, the toner cartridge 10 is provided with triggering components 12 only at the position corresponding to the guide groove 22 and the triggering components 12 are kept in the extended position. That is, the cartridge body 11 is provided with only two triggering components 12, and the two triggering components 12 are respectively located in two mounting grooves 111, with one triggering component 12 slidingly engaging with one guide groove 22.

[0098] As can be seen from the above, in the toner cartridge production process, all components except the triggering component are assembled first. Then, based on the sales region of the toner cartridge, the model of the imaging equipment in that region, and the location of the triggered component in that model of imaging equipment, the triggering component is installed in the mounting slot corresponding to the location of the triggered component. Finally, the toner cartridge is packaged and sold. Alternatively, in the toner cartridge production process, all components except the triggering component are assembled first. The triggering component is included with the toner cartridge when it is sold, and usage instructions are provided near the toner cartridge mounting slot, in the instruction manual, or on the packaging. By using the instructions, users are guided to automatically engage and install the triggering component into the corresponding mounting slot according to the location of the triggered component on their imaging equipment, thus enabling the use of the toner cartridge.

[0099] By separating the trigger component from the cartridge body and then snapping the trigger component into its corresponding mounting slot, manufacturers no longer need to use different molds for production based on the different imaging equipment models and trigger component positions in each sales region. Instead, they can produce the trigger component and cartridge body uniformly, and then install the trigger component in the corresponding mounting slot according to the location of the trigger component in each imaging equipment model before selling to the relevant region. This allows for the use of a single mold to produce different toner cartridge models for various regions, reducing mold costs.

[0100] Alternatively, trigger components that can automatically switch positions can be installed in each mounting slot. Since the guide slots for the triggered components are located in different sales regions on imaging devices, during the toner cartridge installation process, trigger components that are not in contact with the guide slots will automatically switch to the retracted position under the force of the top wall of the imaging device. The trigger components that remain in the extended position will trigger the triggered components inside the imaging device. In this way, the toner cartridge can be used with imaging devices in various sales regions, thereby improving the toner cartridge's versatility, reducing the toner cartridge's production cost, and for consumers, there is no need to distinguish between different versions in different countries and regions; they only need to use the toner cartridge that is compatible with the corresponding printer, thus improving the customer experience.

[0101] Second embodiment of toner cartridge and its installation method, imaging equipment:

[0102] As a description of the second embodiment of the toner cartridge, its installation method, and the imaging device of the present invention, the following description only focuses on the differences from the first embodiment of the toner cartridge, its installation method, and the imaging device described above.

[0103] See Figures 13 to 15 The triggering member 212 also includes a main body 213 and a deformation part 214 arranged at an obtuse angle. In the installation direction of the powder box, the deformation part 214 is located at the downstream end of the triggering member 212, the triggering part 2121 is located on the main body 213 of the corresponding triggering member 212, and the force-bearing part 2124 is located at the end of the deformation part 214 near the main body 213. The box body 211 is provided with a limiting part 2112 at the downstream end near the triggering member 212. The limiting part 2112 extends in a direction away from the mounting groove 2111, and the end of the deformation part 214 away from the main body 213 is sleeved on the limiting part 2112. When the latching part 222 and the buckle 2114 are not disengaged, the deformation part 214 can undergo elastic deformation under the constraint force of the limiting part 2112 on the deformation part 214 and the force on the force-receiving part 2124. After the latching part 222 and the buckle 2114 are disengaged, the elastic restoring force of the deformation part 214 can provide a pulling force to the main body part 213, causing the triggering member 212 to retract into the mounting groove 2111.

[0104] Third embodiment of toner cartridge and its installation method, imaging equipment:

[0105] As a description of the third embodiment of the toner cartridge and its installation method and imaging device of the present invention, the following description only focuses on the differences from the first embodiment of the toner cartridge and its installation method and imaging device described above.

[0106] See Figures 16 to 20 The upstream end of the trigger member 32 is provided with an elastic part 321. When the trigger member 32 is in the extended position, the elastic part 321 abuts against the side wall of the mounting groove 311. When the trigger member 32 is in the retracted position, the elastic part 321 separates from the side wall of the mounting groove 311.

[0107] The elastic part 321 extends in an arc shape. The fixed end of the elastic part 321 is connected to the bottom wall of the trigger member 32. The free end of the elastic part 321 on the trigger member 32 in the extended position abuts against the side wall of the mounting groove 311 near the upstream end of the trigger member 32.

[0108] When in the extended position, the trigger member 32 is limited by the locking action of the latch 314 and the slot 323. Simultaneously, the free end of the elastic part 321 abuts against the mounting groove 311, supporting the trigger member 32 at its front. Thus, the trigger member 32 is stably supported in the extended position through the cooperation of the elastic part 321, the slot 323, and the latch 314. In the retracted position, the elastic part 321 of the trigger member 32 separates from the side wall of the mounting groove 311, keeping the trigger member 32 in the retracted position to avoid interference during toner cartridge loading.

[0109] Fourth embodiment of toner cartridge and its installation method, imaging equipment:

[0110] As a description of the fourth embodiment of the toner cartridge and its installation method and imaging device of the present invention, the following description only focuses on the differences from the first embodiment of the toner cartridge and its installation method and imaging device described above.

[0111] See Figure 21 and Figure 22 When in the extended position, the interference between the trigger member 42 and the mounting groove 411 is S1, and when in the retracted position, the interference between the trigger member 42 and the mounting groove 411 is S2, where S1 < S2. S1 is in the range of 0.01 mm to 0.04 mm, and S2 is in the range of 0.05 mm to 0.15 mm.

[0112] When the toner cartridge is installed, due to the relatively large installation force, and because the triggering component 42, which does not contact the triggered component, directly contacts the top wall of the imaging device's cartridge compartment, the reaction force of the installation force is greater than the frictional force generated by the interference fit between the triggering component 42 and the mounting groove 411, causing the triggering component 42 to continuously move backward and downward, from the extended position to the retracted position.

[0113] The triggering member 42, which abuts against the triggered component, pushes the triggered component under the action of the installation force, causing the triggered component to move away from the toner cartridge, thus triggering the triggered component. Because the displacement of the triggered component greatly weakens the action of the installation force, the reaction force is less than the frictional force generated by the interference fit between the triggering member 42 and the mounting groove 411. After a slight slippage, the triggering member 42 will no longer slide backward and downward. At this point, the triggering member 42 remains in the extended position, abutting and pushing against the triggered component. This allows the toner cartridge to be installed and used normally.

[0114] Therefore, by controlling the magnitude of the frictional force that hinders sliding between the trigger component and the mounting groove through the interference fit, the trigger component can switch from the extended position to the retracted position more effectively, and under the action of friction, the trigger component can be better maintained in the retracted position. At the same time, the trigger component can switch between the extended position during triggering and the retracted position when not triggering, which improves the versatility of the powder box, simplifies the structure of the trigger assembly, and saves production costs.

[0115] Fifth embodiment of toner cartridge and its installation method, imaging equipment:

[0116] As a description of the fifth embodiment of the toner cartridge and its installation method and imaging device of the present invention, the following description only focuses on the differences from the first embodiment of the toner cartridge and its installation method and imaging device described above.

[0117] See Figures 23 to 25 In this embodiment, all six triggering components 52 are fixed in the mounting slot 511. Figure 23 The diagram shows five trigger members 52 in the extended position and one trigger member 52 in the retracted position. In practical applications, the number and specific position of the trigger members 52 held in the retracted position can be selected according to the position and number of guide slots on the imaging device. For example, at least one trigger member 52 can be fixed in the extended position, and the other trigger members 52 can be fixed in the retracted position, or only the trigger members 52 fixed in the extended position can be provided. The trigger part 521 is located on the trigger member 52 in the extended position.

[0118] The maximum distance between the trigger portion 521 on the trigger member 52 in the extended position and the top wall of the housing 51 is the third height value, and the maximum distance between the top of the trigger member 52 in the retracted position and the top wall of the housing 51 is the fourth height value. The third height value is greater than the fourth height value. In other embodiments, the trigger member 12 in the retracted position may also be completely hidden in the corresponding mounting groove 511.

[0119] The triggering member 52 is provided with a slot 522 and a limiting hook 523. The inner wall of the slot 522 is provided with a cantilever 524, and the engaging part 525 is provided at the free end of the cantilever 524. The end of the buckle 514 away from the engaging part 525 is provided with a fastening part 515. The limiting hook 523 is located on the side wall of the triggering member 52 and is engaged with the fastening part 515 downstream of the fastening part 515.

[0120] The triggering member 52 is also provided with a limiting protrusion 526. A relief groove 516 is provided on the side of the movable groove 513 opposite to the buckle 514. The limiting protrusion 526 protrudes from the corresponding side wall of the triggering member 52 in a direction away from the side wall. When the triggering member 52 is in the extended position, the limiting protrusion 526 is located in the relief groove 516. The top wall of the limiting protrusion 526 abuts against the top wall of the relief groove 516. The fixed end of the cantilever 524 is connected to the side wall of the slot 522 away from the limiting protrusion 526. The free end of the cantilever 524 extends toward the limiting protrusion 526 and forms a gap with the limiting protrusion 526.

[0121] Other embodiments of the toner cartridge and its installation method, and imaging equipment:

[0122] In other embodiments, the powder cartridge also includes a trigger module, which includes a base and a trigger member, with a mounting slot located on the base and the base being detachably fixedly connected to the cartridge body.

[0123] The number of mounting slots on the top wall of the box can be more than two, and the specific number, shape and size can be changed as needed.

[0124] The triggering component may also have a snap-fit ​​part on only one of its side walls, and correspondingly, a movable groove may be provided only on the side wall that mates with the snap-fit ​​part.

[0125] During the toner cartridge loading process, one or more triggering components can be kept in the extended position. The number of triggering components kept in the extended position depends on the number of triggered components.

[0126] As mentioned earlier, the number of mounting slots can also be greater than the number of triggering components.

[0127] The number, size, and shape of the triggering components, as well as their fixing or connection methods with the box, can all be changed as needed.

[0128] The positions of the triggering component and the mounting slot on the housing can be changed according to the position of the triggered component in the imaging device.

[0129] The above changes can also achieve the purpose of this invention.

[0130] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
