Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-counterfeiting label technology, and in particular to an anti-counterfeiting label for a filter element RFID chip. Background Technology
[0002] In the fields of industrial equipment maintenance and consumer product anti-counterfeiting, filter elements are key components, making their authenticity verification and usage status tracking crucial. With the widespread adoption of RFID technology, integrating RFID chips into anti-counterfeiting labels and applying them to the surface of filter elements has become an important means of achieving filter element authentication and lifespan monitoring. These filter element RFID chip anti-counterfeiting labels store unique identification information through the chip, and combined with reading and writing devices, can quickly complete the verification of filter element authenticity and data exchange, playing a key role in ensuring the stable operation of industrial equipment and preventing the circulation of counterfeit and substandard products.
[0003] In existing technologies, RFID chip anti-counterfeiting tags for filter cartridges typically employ a basic laminated encapsulation structure. Its mechanical structure mainly includes a chip layer, an antenna layer, a face material layer, and an adhesive backing layer. These layers are bonded together using adhesive and then adhered to the filter cartridge surface. Technically, the chip transmits wireless signals to external reading / writing devices via the antenna. The face material layer primarily serves as dustproofing and basic physical isolation, while the adhesive backing layer secures the tag to the filter cartridge surface. This structural design emphasizes the tag's information storage and retrieval functions, relying solely on the thin face material layer for passive chip protection.
[0004] However, in practical applications, when users replace filter cartridges with RFID chip anti-counterfeiting labels, the chip on the label surface is easily damaged by external impacts or friction due to the limited surface space of the filter cartridge or careless handling. Existing label structures lack specific protective measures for the chip, making it susceptible to physical damage such as circuit breakage and component detachment when accidentally touched. This can lead to the chip being unable to read or write data properly, rendering the filter cartridge unusable due to the anti-counterfeiting label's failure. This problem not only increases user costs but can also cause equipment malfunctions due to misjudgment of filter cartridge authenticity, and even pose safety hazards. It has become a key technical bottleneck restricting the widespread application of RFID chip anti-counterfeiting labels for filter cartridges. Therefore, a filter cartridge RFID chip anti-counterfeiting label is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a filter cartridge RFID chip anti-counterfeiting label, which aims to improve the problem that when people replace filter cartridges with RFID chip anti-counterfeiting labels, they often accidentally damage the chip on the surface of the filter cartridge, making the filter cartridge unusable.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A filter cartridge RFID chip anti-counterfeiting label includes a chip, an antenna electrically connected to the bottom of the chip, release paper disposed at the bottom of the antenna, and a chip protective layer, a face material layer and a transparent protective layer disposed sequentially from bottom to top on the top of the chip.

[0010] As a further description of the above technical solution:
[0011] The transparent protective layer and the surface material layer are fully bonded together.
[0012] As a further description of the above technical solution:
[0013] The chip protective layer is bonded and fixed to the release paper by a substrate adhesive film, which covers the surface of the antenna.
[0014] As a further description of the above technical solution:
[0015] The antenna is composed of multiple rectangular lines.
[0016] As a further description of the above technical solution:
[0017] The chip protective layer has a positioning hole on its inner wall, and the size of the inner wall of the positioning hole is consistent with that of the chip.
[0018] As a further description of the above technical solution:
[0019] The chip is located on the inner wall of the positioning hole, and the bottom of the release paper is provided with adhesive.
[0020] This utility model has the following beneficial effects:
[0021] In this invention, the positioning holes inside the chip protective layer protect both sides of the chip, giving priority to external forces and dispersing the impact force through deformation, greatly reducing the direct effect of external forces on the chip 7, and ultimately achieving the protective effect on the chip. This solves the problem that when people replace filter cartridges with RFID chip anti-counterfeiting labels, they often accidentally damage the chip on the surface of the filter cartridge, making the filter cartridge unusable, thus enhancing the product's protection effect on the chip.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-5This utility model provides an embodiment of an RFID chip anti-counterfeiting label for a filter element, comprising a chip 7, an antenna 6 electrically connected to the bottom of the chip 7 for transmitting and receiving wireless signals, a release paper 8 at the bottom of the antenna 6 to ensure accurate positioning and secure adhesion of the label during installation, preventing premature adhesion of adhesive and affecting the installation effect, and a chip protective layer 4, a face material layer 2, and a transparent protective layer 1 arranged sequentially from bottom to top on the top of the chip 7. The chip protective layer 4 serves as the core of protection, tightly fitting with the chip 7 through positioning holes 9 on its inner wall, ensuring that the chip 7 preferentially disperses the impact force through deformation when subjected to external impact, reducing the risk of damage to the chip 7. The face material layer 2 is bonded and fixed to the chip protective layer 4 with a substrate-free adhesive 3, which provides high-strength adhesion to ensure that the layers remain tightly bonded even in complex environments. Product-related information is printed on the top of the face material layer 2, and its material properties buffer minor impacts, protecting the chip 7 below from damage. The transparent protective layer 1 is fully bonded to the face material layer 2. The transparent protective layer 1 is used to block external pollutants such as dust and moisture, while maintaining the cleanliness and aesthetics of the label surface. The chip protective layer 4 and the release paper 8 are bonded and fixed together by a substrate adhesive film 5. The substrate adhesive film 5 is used to enhance the interlayer bonding strength, ensure the overall structural stability, and cover the surface of the antenna 6, providing additional protection for the antenna 6. The antenna 6 is composed of multiple rectangular lines, and the optimized layout achieves efficient signal transmission while providing space support for the chip 7. The inner wall of the chip protective layer 4 has a positioning hole 9, which is used to accurately fix the position of the chip 7 and prevent the chip 7 from shifting due to shaking during use, which would lead to a decrease in performance. The inner wall size of the positioning hole 9 is consistent with that of the chip 7, ensuring that the chip 7 is evenly stressed after being embedded, reducing local stress concentration. The chip 7 is located on the inner wall of the positioning hole 9. Through the synergistic effect of the release paper 8 on both sides and the chip protective layer 4, it preferentially bears external forces and disperses the impact force through deformation. Adhesive is provided at the bottom of the release paper 8, which is used to firmly bond the label to the filter element surface, ensuring that the label does not fall off during long-term use.
[0031] Working Principle: During product manufacturing, the drilling positions are printed on the surface of the chip protective layer 4. Then, holes are drilled according to the printed positions. After drilling, a surface material layer 2 is applied. Patterns or information are printed on the surface material layer 2 according to the drilling positions, and a transparent protective film is then applied. During this process, substrate-free adhesive 3 and substrate-based adhesive film 5 are used to connect and fix the components, forming the final adhesive surface material, providing excellent protection for the chip 7. This solves the problem in traditional product manufacturing where protruding chips are easily damaged by external forces. In use, the transparent protective layer 1 blocks dust, moisture, and other external contaminants, the printed surface material layer 2 buffers minor impacts and carries the markings, while the substrate-free adhesive 3 and substrate-based adhesive film 5 tightly bond and fix the layers, ensuring overall structural stability and reducing chip 7 vibration. To mitigate the possibility of displacement and damage, antenna 6, while fulfilling signal transmission and reception functions, provides a certain degree of protection for chip 7 in terms of spatial layout. Release paper 8 ensures accurate positioning and secure adhesion during installation. Among them, chip protective layer 4 is the core of protection. The protruding part of chip 7 is embedded in the inner wall of positioning hole 9. The inner walls of positioning hole 9 on both sides of the inner wall of chip protective layer 4 wrap around the protruding part of chip 7. When chip 7 is subjected to external impact and compression, it preferentially bears the external force and disperses the impact force through deformation, greatly reducing the direct effect of external force on chip 7, reducing the defect rate of chip 7, and ultimately achieving the protective effect of chip 7. This solves the problem that when people replace filter cartridges with RFID chip anti-counterfeiting labels, they often accidentally damage the chip 7 on the surface of the filter cartridge, making the filter cartridge unusable, thus enhancing the product's protective effect on chip 7.
