Description

Technical Field

[0001] This invention relates to the field of electronic imaging technology, specifically to a rotating chip mount and processing box. Background Technology

[0002] With the increasing prevalence of printing devices, users are paying more and more attention to the cost and convenience of printing consumables. As a core consumable in printing devices, the toner capacity of the cartridge is typically matched with the capacity data stored in the identification chip located on the cartridge. The chip, as a crucial medium for identifying the cartridge type, recording toner consumption, and performing color calibration, is designed with a capacity that corresponds one-to-one with the original toner capacity—either the maximum number of pages printed or the amount consumed.

[0003] In the compatible consumables market, to reduce user costs and respond to environmental protection initiatives, many compatible cartridges now contain significantly more toner than the original specifications. However, existing compatible chips still adhere to the original chip capacity design, and developing a new high-capacity chip involves high R&D and manufacturing costs, making it uneconomical. This leads to a significant contradiction: when there is still toner remaining in the cartridge, the chip's counting capacity is exhausted, causing the printer to be unable to recognize the cartridge and forcing the user to discontinue use.

[0004] To address the aforementioned issues, some existing processing boxes incorporate quick-release chip sockets on the box body. Users can disassemble the entire chip socket, replace the chip, and reassemble it for continued use. However, this solution has drawbacks: the chip itself is small, making it prone to loss during transportation or storage if sold separately; furthermore, users must disassemble and reassemble the entire chip socket themselves, a cumbersome process involving precise contact alignment, which is extremely inconvenient for ordinary users and hinders its widespread adoption. Summary of the Invention

[0005] The primary objective of this invention is to provide a rotating chip holder that allows users to easily switch chips and achieve timely chip connection.

[0006] A second objective of the present invention is to provide a processing box comprising the aforementioned rotating chip holder.

[0007] To achieve the aforementioned first objective, the present invention provides a rotating chip holder. The rotating chip holder has a rotating part extending axially at its center, and the rotating chip holder can rotate around the rotating part. The rotating chip holder has at least two chip mounting slots and at least two positioning parts arranged circumferentially. All chip mounting slots are arranged at intervals along the circumferential direction of the rotating chip holder. Each chip mounting slot is provided with a clearance for exposing the chip electrical contacts. The clearance is disposed away from the rotating part. All positioning parts are arranged one-to-one with all chip mounting slots. The positioning parts are used to keep the rotating chip holder relatively positioned so that the corresponding chip mounting slot can be kept in a preset working position.

[0008] As can be seen from the above solution, by setting at least two chip mounting slots, the rotating chip holder can simultaneously support at least two chips, and the chip contacts are positioned facing away from the rotating part, facilitating communication with the probes of the printing device. The positioning part ensures that the chips in the mounting slots remain stably in their preset working positions for an extended period. When the currently positioned chip's recognition capacity is exhausted, the user can quickly switch to a spare chip by simply rotating the rotating chip holder, achieving timely chip replacement. This invention avoids high-cost chip development while significantly increasing the chip recognition capacity on the same processing box through a simple tossing operation, solving the pain point of chip installation and removal in large-capacity processing boxes and reducing user costs and operational difficulty. This invention is not only compact and easy to operate, but also eliminates the need for users to purchase replacement chips separately, avoiding the risk of chip loss during storage or transportation due to their small size.

[0009] A further option is to have the rotating part as a central hole, or the rotating part as a central column.

[0010] A further embodiment is that the rotating chip holder is also provided with at least two first elastic latches, and all the first elastic latches are provided in a one-to-one correspondence with all the chip mounting slots; the chip mounting slots extend along the axial direction of the rotating chip holder, and the two ends of the chip mounting slot extension direction are respectively provided with a closed end and an open end, the free end of the first elastic latch is provided in the open end and is provided opposite to the closed end, and the free end of the first elastic latch can move closer to or further away from the closed end.

[0011] As can be seen from the above scheme, through the above settings, the first elastic buckle undergoes elastic deformation during the chip insertion into the chip mounting slot and automatically resets after insertion, thereby confining the chip within the chip mounting slot. This effectively prevents the chip from accidentally coming loose due to vibrations during printing or accidental touches by the user. Furthermore, when the user applies a predetermined amount of external force to pull it out, the first elastic buckle can deform again to release the chip, thus achieving a detachable connection between the chip and the chip mounting slot.

[0012] A further embodiment is that the rotating chip holder also has at least two grooves, all of which correspond one-to-one with all chip mounting slots, and the grooves are located between the chip mounting slots and the rotating part, and the grooves are connected to the chip mounting slots; the connecting end of the first elastic buckle is located in the groove, and the free end of the first elastic buckle extends inclinedly towards the open end.

[0013] A further option is that the rotating chip holder is also provided with at least two positioning ribs, which are located between two adjacent chip mounting slots; the positioning part is located on the side wall or peripheral wall of the positioning ribs.

[0014] As can be seen from the above scheme, through the above settings, under the cooperation of the positioning part and the positioning mating part of the processing box, it can be locked at a preset rotation angle position. When it is at this rotation angle position, the corresponding chip mounting slot and the chip inside are exactly in the preset working position, so that the chip can be aligned and connected with the probe of the printing device, ensuring that the device can read the chip data normally. The positioning part not only ensures the accuracy of the chip and probe alignment each time, but also avoids communication interruption caused by unexpected rotation.

[0015] A further design is to include a push-receiving part on the rotating chip holder, which is located on one side of the chip mounting slot.

[0016] As can be seen from the above scheme, through the above settings, the pushing force-receiving part provides a clear external force application point for the rotating chip holder. The circumferential force applied by the user to the pushing force-receiving part is converted into torque that drives the rotating chip holder to rotate, thereby driving the rotating chip holder to rotate. The settings of this embodiment allow the user to complete the rotation switching of the chip holder without the aid of any workpiece, and can do so with just one finger operation, thus improving the convenience of operation.

[0017] A further solution is to provide at least two identification marks for the rotating chip holder, with each chip mounting slot having at least one identification mark and each identification mark having unique identification information.

[0018] As can be seen from the above scheme, through the above settings, users can intuitively distinguish the chips in different chip mounting slots and their corresponding working status by recognizing the markings. When it is necessary to switch chips, the target chip can be selected quickly and accurately, avoiding accidental switching caused by the similar appearance of the chips, thus improving the reliability and efficiency of operation.

[0019] To achieve the second objective mentioned above, the present invention provides a processing box, comprising a processing box body, a first end cover, a second end cover, the aforementioned rotating chip holder, and at least two chips; the first end cover and the second end cover are respectively connected to the two ends of the processing box body, and all chips are disposed on the rotating chip holder, which is rotatably connected between the processing box body and the first end cover, so that any chip can reach a preset working position.

[0020] As can be seen from the above solution, with the above settings, when the identifiable capacity of the chip currently in the preset working position is exhausted, the user only needs to rotate the rotating chip holder to quickly switch the spare chip, which is pre-placed in another chip mounting slot, to the preset working position, achieving timely chip continuity. This solution has the advantages of simple structure and convenient operation. Moreover, the user can complete the chip switching independently without any tools or disassembling / reassembling parts. Furthermore, since multiple chips can be installed simultaneously on the rotating chip holder, the total identifiable capacity of the processing cartridge is multiplied. This allows for reduced operating costs by increasing the processing cartridge capacity or adding toner, while ensuring the normal operation of the printing equipment, effectively maintaining the stability of print quality, and simplifying the user's operational burden.

[0021] A further embodiment is that a rotating fitting part is provided on the first end of the first end cap or the first end of the processing box body, and the rotating fitting part is connected to the rotating part; a positioning fitting part is provided on the first end of the first end cap or the first end of the processing box body, and the positioning fitting part is connected to the positioning part.

[0022] As can be seen from the above scheme, the positioning part can be released and engaged with the positioning mating part on the processing box. When in the engaged state, the rotating chip holder is locked in the current working position. When subjected to a predetermined external force, the positioning part disengages from the positioning mating part, releasing the rotating chip holder for rotation switching. This embodiment realizes the rapid switching between the positioning and rotatable states, and the operation is reliable and does not require the use of external tools.

[0023] A further option is that the rotating mating part is a rotating shaft, the rotating chip holder is sleeved on the outer side of the middle part of the rotating shaft, and the free end of the rotating shaft is provided with a second elastic buckle; the first end of the processing box body or the first end cover is provided with a mounting hole, and the second elastic buckle is connected to the mounting hole.

[0024] As can be seen from the above scheme, through the above settings, the rotating shaft provides rotational support for the rotating chip holder and accurately positions the rotation center, ensuring that when the rotating chip holder is switched to any preset working angle, the contacts of the chip in the current chip mounting slot and the printing device probe can maintain a high degree of consistent and accurate alignment, ensuring a stable and reliable communication connection. On the other hand, the second elastic buckle on the rotating shaft connects with the mounting hole, which can effectively enhance the connection strength between the first end cover and the main body of the processing box, so that the processing box can maintain the stability of the overall structure even under harsh environments such as long-term use or transportation vibration.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] Rotating chip socket example: See Figures 1 to 4 This embodiment provides a rotating chip holder 1, on which two or more chips 2 can be mounted. This embodiment takes mounting three chips 2 as an example. The three chips 2 are all of the same model and can all communicate with the probes of the same printing device.

[0037] When the current chip 2's recognition capacity is exhausted while there is still toner remaining in the cartridge, the user can quickly switch to a new chip 2 by rotating the chip holder 1 so that the printing device can continue printing.

[0038] The rotating chip holder 1 has a rotating part 11 extending axially at its center, and the rotating chip holder 1 can rotate around the rotating part 11 under the action of external force. The rotating part 11 is a central hole, or the rotating part 11 is a central post, and the former is preferred in this embodiment.

[0039] The rotating chip holder 1 is provided with at least two chip mounting slots 12, at least two first elastic buckles 13 and at least two positioning parts 14 in the circumferential direction. In this embodiment, three chip mounting slots 12, three first elastic buckles 13 and three positioning parts 14 are used as an example.

[0040] Three chip mounting slots 12 are evenly spaced along the circumference of the rotating chip holder 1, and each chip mounting slot 12 is recessed into the peripheral wall of the rotating chip holder 1. Each chip mounting slot 12 has a clearance for exposing the chip contacts, and this clearance is positioned away from the rotating part. Every 60° rotation of the rotating chip holder 1 allows the chip 2 in one of the chip mounting slots 12 to reach a preset working position. This preset working position refers to the position where the contacts of the chip 2 in that chip mounting slot 12 can communicate with the probes in the printing device.

[0041] All positioning parts 14 are correspondingly arranged with all chip mounting slots 12, and the positioning parts 14 and their corresponding chip mounting slots 12 are respectively arranged on both sides of the rotating part 11. In the circumferential direction, the positioning parts 14 and the corresponding chip mounting slots 12 are spaced apart by a preset angle. This preset angle matches the angle between the predetermined working position and the positioning mating part 43 of the processing box. In this embodiment, the preset angle is greater than 90° and less than or equal to 180°.

[0042] The chip mounting groove 12 extends axially along the rotating chip holder 1, and a closed end 121 and an open end 122 are respectively provided at both ends of the extending direction of the chip mounting groove 12. The open end 122 is also provided with an inlet 123 extending radially along the rotating chip holder 1, and the inlet 123 communicates with the chip mounting groove 12. The cross-sectional shape of the chip mounting groove 12 is an "L" structure.

[0043] Chip 2 is fixedly connected to chip mounting slot 12, or chip 2 is detachably connected to chip mounting slot 12; the latter is preferred in this embodiment. Specifically, the free end of the first elastic latch 13 is disposed within the open end 122 and opposite to the closed end 121, and the free end of the first elastic latch 13 can move closer to or further away from the closed end 121. Chip 2 is located between the first elastic latch 13 and the closed end 121. In the extending direction of chip mounting slot 12, the first elastic latch 13 can prevent chip 2 from accidentally detaching from chip mounting slot 12.

[0044] The rotating chip holder 1 also has at least two grooves 15, the number of which is equal to the number of chip mounting slots 12, and all grooves 15 correspond one-to-one with all chip mounting slots 12. The grooves 15 are located between the chip mounting slots 12 and the rotating part 11, and the grooves 15 communicate with the chip mounting slots 12.

[0045] Chip 2 includes a board body 21, electrical contacts 22, and a storage unit 23. The electrical contacts 22 are disposed on a first side of the board body 21, and the storage unit 23 is protrudingly disposed on a second side of the board body 21, with the first side and the second side being opposite to each other. When chip 2 is disposed in chip mounting slot 12, the storage unit 23 is disposed in recess 15, and the electrical contacts 22 are located in a clearance position.

[0046] The connecting end of the first elastic buckle 13 is located in the middle of the bottom 431 of the groove 15. The free end of the first elastic buckle 13 extends inclinedly towards the opening end 122. The free end of the first elastic buckle 13 can swing elastically around its connecting end, so that the chip 2 can be installed and removed by swinging the first elastic buckle 13 at a small angle, making it convenient for manufacturers or users to easily install and remove the chip 2.

[0047] The rotating chip holder 1 is also provided with at least two positioning ribs 16, the number of which is equal to the number of positioning parts 14, and the positioning ribs 16 and positioning parts 14 are arranged in a one-to-one correspondence. The positioning ribs 16 are arranged between two adjacent chip mounting slots 12.

[0048] The positioning part 14 is disposed on the peripheral wall or side wall of the positioning rib plate 16. In this embodiment, the positioning part 14 is disposed on the peripheral wall of the positioning rib plate 16, and the positioning part 14 is configured as an outwardly protruding arc-shaped protrusion.

[0049] To facilitate the rotation of the rotating chip holder 1 around its rotating part 11, the rotating chip holder 1 is also provided with a plurality of pushing force receiving parts 17, and each chip mounting slot 12 is provided with at least one pushing force receiving part 17. The pushing force receiving parts 17 protrude outward, so that the user's fingers can act on the pushing force receiving parts 17 and apply a force that can drive the rotating chip holder 1 to rotate.

[0050] In this embodiment, push-receiving parts 17 are provided on both sides of the chip mounting slot 12, which facilitates the user to push the rotating chip holder 1 to rotate in either the forward or reverse direction. The push-receiving parts 17 and the corresponding positioning parts 14 of the same chip mounting slot 12 are respectively provided on both sides of the rotating part 11.

[0051] To facilitate quick identification of the chip mounting slot 12 by users, the rotating chip holder 1 is also provided with at least two identification marks 18. Each chip mounting slot 12 corresponds to at least one identification mark 18, and each identification mark 18 has unique identification information. For example, the first identification mark is a strip-shaped groove, the second identification mark is two parallel strip-shaped grooves, and the third identification mark is three parallel strip-shaped grooves. In other embodiments, the identification marks can be raised structures, numbers, or letters, etc.

[0052] Identification mark 18 is disposed on at least one side of chip mounting slot 12. In this embodiment, it is preferably disposed on both sides of chip mounting slot 12, and identification mark 18 and pushing force receiving part 17 are arranged along the extending direction of chip mounting slot 12. Identification mark 18 can be disposed on the top wall of chip mounting slot 12, which is beneficial for simplifying the structure.

[0053] In this embodiment, the rotating chip holder 1 has arc-shaped grooves 19 on both sides of the positioning rib plate 16. The arc-shaped grooves 19 are located between two adjacent chip mounting slots 12, and the opening of each arc-shaped groove 19 faces away from the rotating part 11. On the one hand, both sides of the opening of each arc-shaped groove 19 can form a pushing force receiving part 17 for the rotating chip holder 1. On the other hand, the setting of the arc-shaped grooves 19 can reduce the weight of the rotating chip holder 1 while ensuring its structural strength, and also save materials.

[0054] In this embodiment, the rotating chip holder 1 is integrally molded from plastic material.

[0055] Processing box example: See Figures 5 to 8 and combined Figure 2 The processing box provided in this embodiment includes a processing box body 3, a first end cover 4, a second end cover 5, a rotating chip holder 1 as described in the above embodiment, and at least two chips 2. This embodiment takes three chips 2 as an example.

[0056] The first end cap 4 and the second end cap 5 are respectively connected to the two ends of the processing box body 3 along its length, and all chips 2 are mounted on the rotating chip holder 1. The rotating chip holder 1 is rotatably connected between the processing box body 3 and the first end cap 4, so that any chip 2 on the rotating chip holder 1 can reach a preset working position.

[0057] A rotating fitting part 41 is provided on the first end of the first end cap 4 or the first end of the processing box body 3, and the rotating fitting part 41 is connected to the rotating part 11. A positioning fitting part 43 is provided on the first end of the first end cap 4 or the first end of the processing box body 3, and the positioning fitting part 43 is connected to the positioning part 14. The rotating fitting part 41 and the positioning fitting part 43 can be provided on the first end cap 4 or the processing box body 3 at the same time, or they can be provided on the first end cap 4 or the processing box body 3 respectively, which is not limited here.

[0058] In this embodiment, a rotating engagement portion 41, a positioning engagement portion 43, and a clearance opening 45 are provided on one side of the first end cover 4. The clearance opening 45 is located above the rotating engagement portion 41 and extends radially through the side wall 46 of the first end cover 4, serving to avoid the rotating chip holder 1, allowing the chip 2 in a preset working position on the rotating chip holder 1 to be exposed within the clearance opening 45 for connection with the probe of the printing device. The rotating engagement portion 41 is a rotating shaft protruding from the end wall 47 of the first end cover 4. The rotating shaft can be inserted into the central hole of the rotating chip holder 1, allowing the rotating chip holder 1 to rotate around the rotating shaft. The length of the rotating shaft is greater than the thickness of the rotating chip holder 1, allowing the free end of the rotating shaft to penetrate the rotating chip holder 1. The free end of the rotating shaft is provided with two second elastic latches 44, which are arranged back-to-back and can elastically swing closer to each other.

[0059] The first end of the processing box body 3 is provided with a mounting hole 30, which is correspondingly provided with the rotating mating part 41. Two second elastic buckles 44 are inserted into the mounting hole 30 and engaged with the mounting hole 30, so that the first end cover 4, the rotating chip holder 1 and the first end of the processing box body 3 are firmly connected, effectively reducing the installation difficulty and improving production efficiency.

[0060] While serving as the end cap of the processing box body 3, the first end cap 4 also functions as a rotating support for the rotating chip holder 1. On the one hand, the connection strength between the first end cap 4 and the processing box body 3 is enhanced, ensuring that the overall structure of the processing box remains stable under long-term use or transportation vibration. On the other hand, the first end cap 4 provides precise rotation center positioning for the rotating chip holder 1, constraining the free ends of its rotation axis in the radial and axial directions. This ensures that after the rotating chip holder 1 is switched to any preset working angle, the electrical contacts 22 on the chip 2 in the current chip mounting slot 12 can maintain a consistent and precise alignment with the printing device probe, ensuring a stable and reliable communication connection.

[0061] In this embodiment, the positioning fitting part 43 is disposed on one side of the rotating fitting part 41. Preferably, the positioning fitting part 43 is disposed on the end wall 47 of the first end cover 4 and located below the rotating fitting part 41. The positioning fitting part 43 is preferably a positioning groove. Specifically, a rib 42 is provided on the end wall 47 of the first end cover 4, and the positioning fitting part 43 is disposed on the rib 42, with the groove of the positioning fitting part 43 facing upward. Arc-shaped transition parts 432 are provided on both sides of the groove of the positioning fitting part 43, and the bottom 431 of the groove of the positioning fitting part 43 is lower than the arc-shaped transition parts 432.

[0062] When the positioning part 14 is embedded in the positioning mating part 43, the arc-shaped transition part 432 can prevent the positioning part 14 from separating from the positioning mating part 43 if no external force is applied. When a rotational force is applied to the rotating chip holder 1, the positioning part 14 can slide along the surface of the arc-shaped transition part 432 to disengage from the positioning mating part 43.

[0063] The main body 3 of the processing box is equipped with a powder hopper 31, a developing hopper 32, a powder feeding roller 33, a developing roller 34, a powder feeding blade 35, a photosensitive drum 36, a charging roller 37, a cleaning scraper 38, and a waste powder hopper 31.

[0064] The toner hopper 31 stores toner and has a toner filling port. The developing hopper 32 is connected to the toner hopper 31. The toner delivery roller 33 and the developing roller 34 are rotatably mounted inside the developing hopper 32 and are connected to each other to deliver toner onto the developing roller 34. The photosensitive drum 36 is connected to both the charging roller 37 and the developing roller 34. The developing roller 34 delivers toner onto the photosensitive drum 36 intermittently. A cleaning blade 38 is located at the entrance of the waste toner hopper 31 and is used to clean any remaining waste toner from the surface of the photosensitive drum 36.

[0065] In summary, this invention, by providing at least two chip mounting slots, allows the rotating chip holder to simultaneously support at least two chips, with the chip contacts positioned away from the rotating part for easy communication with the probes of the printing device. The positioning part ensures that the chips within the mounting slots remain stably in their preset working positions for an extended period. When the currently positioned chip's recognition capacity is exhausted, the user can quickly switch to a spare chip by simply rotating the rotating chip holder, enabling timely chip replacement. This invention avoids high-cost chip development while significantly increasing the chip recognition capacity on the same processing cartridge through a simple tossing operation, solving the pain point of chip installation and removal in large-capacity processing cartridges and reducing user costs and operational complexity. Furthermore, this invention is not only compact and easy to operate, but also eliminates the need for users to purchase replacement chips separately, preventing the risk of chip loss during storage or transportation due to their small size.

[0066] 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.
