Description

Technical Field

[0001] This invention relates to the field of printing equipment consumables technology, and in particular to a copier consumable chip and its usage method. Background Technology

[0002] As the core electronic identification unit of the toner cartridge, the copier consumable chip plays a crucial role in equipment authentication, toner level monitoring, and data transmission. With the widespread adoption of industrial-grade high-speed printing equipment, the peak current continuously carried by the chip has increased from the traditional 0.5A to over 2.0A. During repeated power-on / power-off cycles, the metal contacts experience a sudden rise in localized temperature due to Joule heat buildup, leading to contact oxidation and deformation, and a significant increase in contact resistance. This severely restricts the long-term operational stability of the printing equipment and the lifespan of the consumables.

[0003] Current mainstream solutions employ electronic reset protection circuits (such as PTC resettable fuses), which achieve overload tripping through the sudden change in resistance of positive temperature coefficient materials, and automatically resume conduction after the temperature drops. The mechanical structure relies on the vertical pressing of spring pin contacts, and heat dissipation is achieved solely through two-dimensional heat diffusion via thermal grease mounted on an aluminum substrate.

[0004] While electronic reset solutions enable circuit self-recovery, they also pose a risk of malicious exploitation: third-party consumable manufacturers can force the reset of faulty chips through external circuits, bypassing the original manufacturer's certification mechanism, leading to the failure of copyright protection and rampant illegal refilling, which seriously infringes on the intellectual property rights and market interests of equipment manufacturers. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a copier consumable chip and its usage method.

[0006] In a first aspect, this application provides a copier consumable chip, including a chip body, a cover for storing the chip body, a copier toner cartridge, and further comprising: A base mounted on the bottom of the chip body and a chip protrusion mounted on the top of the chip body, wherein the surface of the chip protrusion is integrated with metal contact parts, and an alloy material cavity is provided on the lower side inside the chip body, and the metal contact parts are connected to the alloy material cavity. A heat dissipation mechanism, comprising multiple heat dissipation fins, which are vertically connected to the middle of the base, and copper tubes are inserted through the heat dissipation fins. A protective mechanism is located at the edge of the chip body to provide protection; The disassembly and assembly mechanism is located on the surface of the chip body and inside the cover, and is used for quick positioning and disassembly / assembly.

[0007] Optionally, the protective mechanism includes protective protrusions on the front and rear sides of the chip body edge, and edge fixing seats on the left and right sides of the chip body edge, wherein a limiting protrusion is fixed on the outer wall of one of the edge fixing seats, and the edge fixing seat can be directly snapped into the inner wall of the chip placement seat on one side of the outer wall of the box cover.

[0008] Optionally, the chip body is connected to the copier toner cartridge via a cover, and a chip holder is installed inside the cover for placing the chip body.

[0009] Optionally, the disassembly and assembly mechanism includes insulating connectors disposed at both ends of the chip body and chip fixing clips pre-set inside the insulating connectors. Both sides of the chip placement seat are provided with chip fixing clips that engage with the chip fixing clips.

[0010] Optionally, the chip placement base has a sliding groove inside for the chip body to slide with the limiting protrusion, and a rubber buffer pad is provided in the middle of the chip placement base to protect the chip body.

[0011] Optionally, the limiting protrusion is provided on the lower side of the outer wall of the edge fixing seat to prevent the chip body from being placed upside down.

[0012] Optionally, the copier toner cartridge has multiple positioning posts installed inside, each positioning post having a connector inside, and the end of the connector having a contact point that mates with a metal contact portion.

[0013] Optionally, a limiting ring is fixed in the middle of the outer wall of the connector, and a spring is sleeved on the outer wall of the connector near the limiting ring.

[0014] Optionally, one end of the spring is fixed inside the positioning post, and the other end of the spring is fixed to the outer wall of the limiting ring, and the spring is made of insulating material.

[0015] Secondly, the present invention provides a method for using a copier consumable chip, applied to the copier consumable chip described in the first aspect, the method comprising the following steps: S1. Place the chip body into the chip placement seat of the cover, so that the protective protrusion is embedded in the groove of the chip placement seat; S2: Press down the chip body to engage and lock the chip fixing female buckle in the insulating connector with the chip fixing female buckle in the chip placement seat; S3. Push the lid so that the edge fixing seat is engaged in the groove on the inner wall of the copier toner cartridge, and at the same time the limiting protrusion abuts against the end of the slide groove. S4. Press the box cover to move the connector inside the positioning column forward, the spring is compressed and pushes the limit ring, and the contact point presses against the metal contact part; S5. The rubber buffer pad deforms, providing elastic support for the chip body and the copier toner cartridge.

[0016] In summary, this application includes at least one of the following beneficial technical effects: This invention features an irreversible disconnection protection mechanism that forms a permanent insulation barrier through alloy melting and solidification, physically locking the circuit to prevent third-party reset and cracking, and eliminating the possibility of third parties forcibly resetting it through external circuits, thus blocking the path of illegal filling of consumables at the source.

[0017] Further expansion of the heat dissipation fins enhances the horizontal heat diffusion, while copper tubes construct an axially efficient heat conduction channel. The alloy cavity actively absorbs heat through molten flow. The heat dissipation fins, copper tube heat channels, and alloy cavity form a three-stage heat dissipation path that works together to reduce the peak temperature at the contact point and slow down the metal oxidation process.

[0018] Finally, the edge protection protrusion absorbs lateral impact, and the limiting protrusion prevents over-displacement; the male and female interlocking locks to prevent accidental loosening, and the rubber buffer pad dampens vertical vibration, together forming a damage prevention and disassembly protection system. The spring pushes the connector forward through the limiting ring, so that the constant pressure metal contact part at the contact point maintains a low resistance path in the equipment vibration environment, ensuring the continuity of current and data transmission.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-7 As shown, the present invention proposes a copier consumable chip, including a chip body 1, a cover 12 for storing the chip body 1, and a copier toner cartridge 16; in one embodiment, the chip body 1 is disposed between the cover 12 and the copier toner cartridge 16, a base 5 is installed at the bottom of the chip body 1, and a chip protrusion 2 is installed at the top, a metal contact portion 3 is integrated on the surface of the chip protrusion 2, and an alloy material cavity 4 is provided on the lower side inside the chip body 1, and the metal contact portion 3 is connected to the alloy material cavity 4; The chip body 1 is connected to the copier toner cartridge 16 via a cover 12. A chip placement holder 13 is installed inside the cover 12 for placing the chip body 1. The following is a detailed description of the consumable chip: In this embodiment, the chip body 1 is fixedly mounted on the base 5 at the bottom and a chip boss 2 is provided on the top. The metal contact part 3 integrated on the surface of the chip boss 2 is directly connected to the internal alloy material cavity 4. Normal operating condition heat dissipation path: The Joule heat generated by the metal contact part 3 when energized is conducted to the base 5 through the chip body 1. The heat dissipation fins 6 vertically distributed at the bottom of the base 5 enhance horizontal heat diffusion by increasing the surface area. The copper tube 7 that runs through the fins uses the high thermal conductivity of copper to establish a longitudinal heat transfer channel, transferring the heat gradient to the far end of the fins, significantly improving the air convection heat dissipation efficiency. Active overload protection: When the metal contact portion 3 heats up to above 138°C due to overload current, the heat is conducted to the alloy chamber 4 via vertical microchannels, where the bismuth-tin alloy melts and liquefies. Driven by the crack channels and thermal expansion pressure, the liquid alloy flows upward along the microchannels to the crack area of ​​the metal contact portion 3. After the liquid alloy contacts the relatively low-temperature contact crack matrix (<100°C), it solidifies within 1-3 seconds, forming a dense metal barrier. This barrier physically blocks the conductive path of the metal contact portion 3, achieving permanent circuit disconnection. The solidification process is accompanied by a 3.1% volume expansion, ensuring tight filling of the cracks, permanently disconnecting the circuit, and eliminating the risk of secondary short circuits. At the same time, the solidified alloy marks provide direct evidence of the fault, eliminating the risk of false short circuits or arc reignition that may be caused by traditional electronic reset solutions. Then, a new chip can be replaced. It also avoids losses caused by third parties being unable to force reset through external circuits.

[0023] like Figures 1-3 As shown, the consumable chip also includes a heat dissipation mechanism; in one embodiment, the heat dissipation mechanism includes multiple heat dissipation fins 6, which are vertically connected to the middle of the base 5, and copper tubes 7 are disposed inside the heat dissipation fins 6. The heat dissipation mechanism is described in detail below: In this embodiment, multiple parallel heat dissipation fins 6 are vertically installed at the bottom of the base 5, and a copper tube 7 is installed through the middle of the heat dissipation fins 6. During operation, the heat conducted by the base 5 diffuses through the surface of the heat dissipation fins 6; the copper tube 7 acts as a heat conduction enhancement channel to transfer the heat flow longitudinally, so that the heat is distributed along the gradient of the fin array. The physical connection of the copper tube 7 through the fins forms a continuous heat conduction path.

[0024] like Figures 1-3 As shown, the consumable chip also includes a protective mechanism located at the edge of the chip body 1. In one embodiment, the protective mechanism includes protective protrusions 8 on the front and rear sides of the chip body 1, and edge fixing seats 22 on the left and right sides of the chip body 1. One edge fixing seat 22 has a limiting protrusion 9 fixed to its outer wall. The edge fixing seat 22 can be directly engaged with the inner wall of the chip placement seat 13 on one side of the outer wall of the cover 12. The protective mechanism is described in detail below: In this embodiment, the protective protrusion 8 is located on the left and right edges of the chip body 1, the limiting protrusion 9 is located outside the protective protrusion 8, and the edge fixing seat 22 is fixed to the side wall of the cover 12. During installation, the chip placement seat 13 inside the cover 12 supports the chip body 1, and the edge fixing seat 22 is inserted into the groove of the inner wall of the copier toner cartridge 16. The protective protrusion 8 slides in the groove of the chip placement seat 13, and the limiting protrusion 9 abuts against the end of the groove to prevent overtravel.

[0025] like Figures 1-5As shown, the consumable chip also includes a disassembly and assembly mechanism disposed on the surface of the chip body 1 and inside the cover 12; as one embodiment, the disassembly and assembly mechanism includes an insulating connector 10 disposed at both ends of the chip body 1 and a chip fixing buckle 11 preset inside the insulating connector 10, and chip fixing female buckles 14 that engage with the chip fixing buckle 11 are provided on both sides inside the chip placement seat 13. The chip placement base 13 has a sliding groove inside for the chip body 1 to slide against the limiting protrusion 9, and a rubber buffer pad 15 is provided in the middle of the chip placement base 13 to protect the chip body 1; the limiting protrusion 9 is located on the lower side of the outer wall of the edge fixing base 22 to prevent the chip body 1 from being placed upside down. The disassembly and assembly mechanism is described in detail below: In this embodiment, the protective protrusion 8 is located on the left and right edges of the chip body 1, the limiting protrusion 9 is located outside the protective protrusion 8, and the edge fixing seat 22 is fixed to the side wall of the cover 12. During installation, the chip placement seat 13 inside the cover 12 supports the chip body 1, and the edge fixing seat 22 is inserted into the groove of the inner wall of the copier toner cartridge 16. The protective protrusion 8 slides in the groove of the chip placement seat 13, and the limiting protrusion 9 abuts against the end of the groove to prevent overtravel.

[0026] like Figures 1-8 As shown, the consumable chip also includes a plurality of positioning posts 17 installed inside the copier toner cartridge 16; in one embodiment, a connector 18 is provided inside the positioning post 17, and a contact point 21 is provided at the end of the connector 18 to cooperate with the metal contact part 3. A limiting ring 19 is fixed in the middle of the outer wall of the connector 18, and a spring 20 is sleeved on the outer wall of the connector 18 near the limiting ring 19; one end of the spring 20 is fixed inside the positioning post 17, and the other end of the spring 20 is fixed to the outer wall of the limiting ring 19, and the spring 20 is made of insulating material. The consumable chip is described in detail below: In this embodiment, the positioning post 17 on the inner wall of the copier toner cartridge 16 is inserted into the connector 18. The connector 18 has a contact point 21 at its end and a fixed limiting ring 19 in the middle. When installed in place, the two ends of the spring 20 press against the inner wall of the positioning post 17 and the surface of the limiting ring 19 respectively, pushing the connector 18 forward so that the contact point 21 presses against the metal contact part 3. When disassembled, the spring 20 compresses and releases the connector 18 to retract.

[0027] like Figures 1-9 As shown, the present invention also provides a method for using a copier consumable chip, the method comprising the following steps: S1. Place the chip body 1 into the chip placement seat 13 of the cover 12, so that the protective protrusion 8 is embedded in the groove of the chip placement seat 13. S2: Press down the chip body 1 to make the chip fixing female buckle 11 in the insulating connector 10 engage and lock with the chip fixing female buckle 14 in the chip placement seat 13; S3. Push the lid 12 so that the edge fixing seat 22 is inserted into the groove of the inner wall of the copier toner cartridge 16, and at the same time the limiting protrusion 9 abuts against the end of the slide groove. S4. Press the box cover 12 to move the connector 18 inside the positioning post 17 forward. The spring 20 compresses and pushes the limiting ring 19, and the contact point 21 presses against the metal contact part 3. S5, the rubber buffer pad 15 deforms to provide elastic support for the chip body 1 and the copier toner cartridge 16.

[0028] Specifically, the chip body 1 is placed into the chip placement seat 13 of the cover 12, so that the protective protrusion 8 on the edge of the base 5 is embedded in the guide grooves on both sides of the chip placement seat 13; the limiting protrusion 9 abuts against the side wall of the groove to prevent the chip body 1 from being placed in the wrong direction; the rubber buffer pad 15 at the bottom of the chip placement seat 13 contacts the bottom surface of the chip body 1.

[0029] When the chip body 1 is pressed down, the chip fixing buckle 11 in the insulating connector 10 moves down along the slide groove and engages with the chip fixing female buckle 14 inside the chip placement seat 13 to lock; the rubber buffer pad 15 undergoes elastic deformation under pressure to provide vertical buffering.

[0030] Push the cover 12 so that the edge fixing seat 22 of the cover 12 engages with the matching groove on the inner wall of the copier toner cartridge 16; the protective protrusion 8 slides smoothly along the slide until the limiting protrusion 9 abuts the end of the slide, limiting the displacement of the cover 12.

[0031] When the lid 12 is fully closed, the positioning post 17 inside the copier toner cartridge 16 presses against the connector 18; the connector 18 moves forward against the resistance of the spring 20, so that the contact point 21 at the end presses against the metal contact part 3 of the chip boss 2; the spring 20 maintains a stable contact pressure through the limiting ring 19.

[0032] Current flows through contact point 21 to metal contact part 3. Base 5 conducts heat to heat dissipation fins 6, and copper tube 7 enhances longitudinal heat transfer. If metal contact part 3 heats up due to overload, the low melting point alloy in alloy cavity 4 melts and flows to the contact area. When the overload current triggers the alloy to melt and solidify to form an insulating barrier, the circuit is permanently cut off (resistance > 100MΩ), the current path is completely blocked, the heat source disappears, and the overload condition terminates automatically. The solidified bismuth-tin alloy combines with the substrate of metal contact part 3 to form a permanent composite structure, requiring no manual cleaning. It remains in place as a physical fault marker of the chip. Users need to replace the entire failed chip, and the residual alloy enters the recycling process with the old chip. Because bismuth-tin alloy is non-toxic and has a low melting point (138℃), it can be efficiently separated and recycled through standard electronic waste smelting processes.

[0033] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
