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 nano water display chip. Background Technology

[0002] Anti-counterfeiting labels, also known as anti-counterfeiting marks or anti-counterfeiting trademarks, are marks that can be affixed, printed, or transferred to the surface of a product, its packaging, or its accessories (such as product tags, business cards, and anti-counterfeiting certificates) to prevent counterfeiting. Currently, most anti-counterfeiting labels on the market typically rely on simple anti-counterfeiting patterns or QR codes, which are easily counterfeited and have poor anti-counterfeiting effects. Utility Model Content

[0003] The main purpose of this invention is to propose a nano water display chip anti-counterfeiting label, which aims to improve the anti-counterfeiting properties of the label.

[0004] To achieve the above objectives, the present invention proposes a nano-water indicator chip anti-counterfeiting label, comprising:

[0005] Substrate layer;

[0006] A first printing layer and a communication layer are stacked on opposite sides of the substrate layer. The first printing layer is provided with first anti-counterfeiting information, and the communication layer is pre-stored with second anti-counterfeiting information and is used to transmit the second anti-counterfeiting information to an external device.

[0007] A water-reflective film layer is provided, which covers the side of the first printed layer away from the substrate layer. The water-reflective film layer has a water-reflective state and a cover state. When the water-reflective film layer is in the water-reflective state, it is transparent to reveal the first anti-counterfeiting information on the first printed layer.

[0008] In one embodiment, the communication layer includes an NFC chip, a radio frequency antenna, and a detection antenna. The radio frequency antenna is electrically connected to the NFC chip and is used to communicate with external devices. The NFC chip pre-stores the second anti-counterfeiting information. The detection antenna forms a sensing loop and is electrically connected to the NFC chip. The NFC chip is configured to change the status code of the second anti-counterfeiting information when it senses that the sensing loop is disconnected.

[0009] In one embodiment, the nano water display chip anti-counterfeiting label further includes a first adhesive layer, which is bonded between the substrate layer and the communication layer.

[0010] In one embodiment, the nano water display chip anti-counterfeiting label further includes a second adhesive layer, which is bonded to the side of the communication layer opposite to the substrate layer.

[0011] In one embodiment, the second adhesive layer is a pressure-sensitive adhesive.

[0012] In one embodiment, the nano water display chip anti-counterfeiting label further includes a release paper layer, which is bonded to the substrate layer by the second adhesive layer.

[0013] In one embodiment, the orthographic projection of the substrate layer in a direction perpendicular to the surface falls into the release paper layer, and the outline of the orthographic projection is spaced from the edge of the release paper layer.

[0014] In one embodiment, the water-display film layer, the first printing layer, the substrate layer, the communication layer, and the second adhesive layer are stacked in sequence to form an anti-counterfeiting label unit. Multiple anti-counterfeiting label units are disposed on the same release paper layer through their respective second adhesive layers to form a nano water-display chip anti-counterfeiting label array.

[0015] In one embodiment, the anti-counterfeiting label of the nano water display chip further includes a second printing layer, which covers the side of the water display film layer opposite to the first printing layer, and the second printing layer is provided with visible identification information.

[0016] In one embodiment, the nano water display chip anti-counterfeiting label further includes a third adhesive layer, which is bonded between the water display film layer and the first printing layer.

[0017] In one embodiment, the substrate layer is made of fragile paper.

[0018] In one embodiment, the water-reflective membrane layer is a porous membrane.

[0019] The technical solution of this utility model constructs a first layer of anti-counterfeiting barrier through the physical covering and water-reflective properties of the water-reflective film layer. This allows the first anti-counterfeiting information on the first printed layer to be hidden when the water-reflective film layer is covered and revealed when the water-reflective film layer is in a water-reflective state. Simultaneously, a second layer of anti-counterfeiting information pre-stored in the communication layer serves as a second layer of anti-counterfeiting barrier, achieving digital anti-counterfeiting. The nano-water-reflective chip anti-counterfeiting label of this utility model achieves dual anti-counterfeiting through the combination of the water-reflective visibility of the first printed layer and electronic verification of the communication layer, thus improving the anti-counterfeiting label's security.

[0031] This invention proposes an anti-counterfeiting label for a nano water display chip.

[0032] Please see Figure 1 In one embodiment of this utility model, the nano water-display chip anti-counterfeiting label includes a substrate layer 500, a water-display film layer 200, a first printing layer 400, and a communication layer 700. The first printing layer 400 and the communication layer 700 are stacked and disposed on opposite sides of the substrate layer 500. The first printing layer 400 is provided with first anti-counterfeiting information, and the communication layer 700 is pre-stored with second anti-counterfeiting information and is used to transmit the second anti-counterfeiting information to an external device. The water-display film layer 200 covers the side of the first printing layer 400 away from the substrate layer 500. The water-display film layer 200 has a water-display state and a covered state. When the water-display film layer 200 is in the water-display state, the water-display film layer 200 is transparent to reveal the first anti-counterfeiting information on the first printing layer 400.

[0033] Specifically, the substrate layer 500, serving as the supporting structure for the entire anti-counterfeiting label, can be made of paper, plastic film, or other flexible materials to support other functional layers. A first printing layer 400 and a communication layer 700 are respectively disposed on two opposite surfaces of the substrate layer 500. The first printing layer 400 is located on one side of the substrate layer 500 and is printed with first anti-counterfeiting information using printing technology. This first anti-counterfeiting information can be text, patterns, logos, serial numbers, invisible ink patterns, etc., providing visual anti-counterfeiting features as the first layer of anti-counterfeiting barrier.

[0034] A water-developing film layer 200 covers the outer surface of the first printed layer 400, i.e., the side facing away from the substrate layer 500. The water-developing film layer 200 has two states: a covered state and a water-developing state, which can be switched using water. Under normal drying conditions, the water-developing film layer 200 is in the covered state, appearing opaque, effectively obscuring the first anti-counterfeiting information on the first printed layer 400, making it invisible and preventing unauthorized viewing or copying. Specifically, the water-developing film layer 200 needs to completely cover the first anti-counterfeiting information on the first printed layer 400 so that it can completely conceal the information when in the covered state. When the surface of the nano-water-developing chip anti-counterfeiting label comes into contact with moisture or water vapor, the water-developing film layer 200 quickly transforms into a water-developing state, appearing transparent or semi-transparent, clearly revealing the underlying first anti-counterfeiting information, achieving a visual anti-counterfeiting effect that reveals itself upon contact with water. After the moisture evaporates, the water-developing film layer 200 can return to the covered state, achieving reversible development. Of course, depending on the material design, the first printing layer 400 can also be developed in one step. The water-developing film layer 200 can be made of water-sensitive materials such as water-soluble coatings or water-chromic materials to achieve controllable display of the first anti-counterfeiting information.

[0035] The communication layer 700 is located on the opposite side of the substrate layer 500 from the first printed layer 400. The communication layer 700 can be a smart communication component such as a QR code, NFC chip 710, RFID (Radio Frequency Identification) tag, or Bluetooth module. The communication layer 700 internally stores second anti-counterfeiting information. This second anti-counterfeiting information can be identified and verified by external reading devices (such as mobile phones, barcode scanners, RFID readers, etc.) through wireless communication technology, achieving electronic information verification and serving as a second layer of anti-counterfeiting. The second anti-counterfeiting information can be encrypted digital codes, such as UUID (Universally Unique Identifier), hash encryption, or other unique serial numbers, or dynamic anti-counterfeiting codes generated by combining timestamps, product batches, and random numbers; it can also be interactive verification information; or it can be a status code.

[0036] The nano-water-display chip anti-counterfeiting label significantly enhances its anti-counterfeiting performance through a combination of multiple anti-counterfeiting mechanisms. First, the physical covering and water-reflective properties of the water-display film layer 200 constitute the first layer of anti-counterfeiting barrier. Counterfeiters find it difficult to replicate this dynamic effect of revealing hidden information as the environment changes, and the hidden content is undetectable in a dry state, increasing the difficulty of counterfeiting. Second, the visual anti-counterfeiting information provided by the first printing layer 400, combined with the water-display function, forms an intuitive and easily identifiable anti-counterfeiting feature. Consumers can perform preliminary verification simply by dripping water or touching the label with wet hands, without the need for professional equipment, improving user experience and anti-counterfeiting credibility. Third, the second layer of anti-counterfeiting information pre-stored in the communication layer 700 serves as a second layer of anti-counterfeiting barrier, achieving digital anti-counterfeiting. It supports linkage with a backend database and can be quickly read and verified via smartphones and other devices, effectively preventing label duplication and information tampering. The nano water-indicating chip anti-counterfeiting label achieves dual anti-counterfeiting through a combination of a first printing layer (400) that is visible when exposed to water and a communication layer (700) that provides electronic verification. This gives the nano water-indicating chip anti-counterfeiting label high security, easy identification, and traceability, effectively solving the problems of easy copying and poor anti-counterfeiting effect of traditional anti-counterfeiting labels, and improving the anti-counterfeiting performance of the label.

[0037] Furthermore, the design of the first printing layer 400 and the communication layer 700 being stacked on opposite sides of the substrate layer 500 can reduce the interference of the ink or metal coating of the first printing layer 400 on the wireless signal, ensuring that external devices can stably read the second anti-counterfeiting information of the communication layer 700; it can also reduce the damage to the communication layer 700 caused by water immersion when the first printing layer 400 is subjected to water-based verification; and it can also reduce the process complexity caused by laminating multiple materials on the same side.

[0038] The technical solution of this utility model constitutes a first layer of anti-counterfeiting barrier through the physical covering and water-reflective properties of the water-reflective film layer 200. This allows the first anti-counterfeiting information on the first printing layer 400 to be hidden when the water-reflective film layer 200 is covered, and to be revealed when the water-reflective film layer 200 is in a water-reflective state. Simultaneously, the second layer of anti-counterfeiting information pre-stored in the communication layer 700 serves as a second layer of anti-counterfeiting barrier, achieving digital anti-counterfeiting. The nano-water-reflective chip anti-counterfeiting label of this utility model achieves dual anti-counterfeiting through the combination of the water-reflective visibility of the first printing layer 400 and the electronic verification of the communication layer 700, thus improving the anti-counterfeiting effectiveness of the label.

[0039] In one implementation, please refer to Figure 1 and Figure 2The communication layer 700 includes an NFC chip 710, a radio frequency antenna 720, and a detection antenna 730. The radio frequency antenna 720 is electrically connected to the NFC chip 710 and is used to communicate with external devices. The NFC chip 710 has a second anti-counterfeiting information pre-stored. The detection antenna 730 forms a sensing loop and is electrically connected to the NFC chip 710. The NFC chip 710 is configured to change the status code of the second anti-counterfeiting information when it senses that the sensing loop is disconnected.

[0040] The NFC chip 710 pre-stores second anti-counterfeiting information. The radio frequency antenna 720 is electrically connected to the NFC chip 710 for wireless communication with external devices. Users can read the second anti-counterfeiting information in the NFC chip 710 using an NFC-enabled device to verify the authenticity of the product. The detection antenna 730 forms a sensing loop and is also electrically connected to the NFC chip 710. The NFC chip 710 can detect when the sensing loop is damaged or broken.

[0041] When a user brings an NFC-enabled device close to the nano-water display chip anti-counterfeiting label, the radio frequency antenna 720 receives the signal and activates the NFC chip 710, allowing the reading of pre-stored second anti-counterfeiting information. The sensing loop formed by the detection antenna 730 remains closed under normal circumstances. If someone attempts to remove or tamper with the nano-water display chip anti-counterfeiting label, the sensing loop will break, detected by the NFC chip 710, and the status code of the second anti-counterfeiting information will be changed. Therefore, once the label is tampered with, even if it is later reattached, the NFC chip 710 can detect it and notify the user that the label is no longer authentic by changing the status code. This effectively prevents criminals from removing the original label from genuine products and reusing it on counterfeit products, increasing the difficulty for counterfeiters to copy or reuse the label, and further enhancing the anti-counterfeiting properties of the nano-water display chip anti-counterfeiting label.

[0042] In one implementation, please refer to Figure 2The NFC chip 710 pre-stores a first anti-counterfeiting information consisting of a digital signature, product information, and a default status code of 0. The NFC chip 710, RF antenna 720, and detection antenna 730 are mounted side-by-side on the same surface of the substrate layer 500. The NFC chip 710 has an I / O interface and a ground interface. One end of the detection antenna 730 is connected to the I / O interface, and the other end is connected to the ground interface. The I / O interface and the ground interface form a closed loop through the detection antenna 730. The detection antenna 730 is used to determine whether the tag has been damaged. When the detection antenna 730 is intact and maintains a closed loop, the status code of the NFC chip 710 is 0. When the detection antenna 730 is damaged and the loop is broken, the NFC chip 710 rewrites the status code to 1 and retains the status code 1. Therefore, when the NFC reader reads a status code of 0, the tag is considered genuine; when the NFC reader reads a status code of 1, the tag is considered counterfeit.

[0043] Among them, the radio frequency antenna 720 and the detection antenna 730 are one of the following: fragile aluminum etched antenna, copper etched antenna, silver etched antenna, printed conductive antenna, or paper-based antenna. The NFC chip 710 is one of the following: high-frequency chip, ultra-high-frequency chip, low-frequency chip, or dual-frequency chip.

[0044] In one implementation, please refer to Figure 1 The nano water display chip anti-counterfeiting label also includes a first adhesive layer 600, which is bonded between the substrate layer 500 and the communication layer 700.

[0045] The first adhesive layer 600 is disposed between the substrate layer 500 and the communication layer 700. Through adhesion, it firmly fixes the communication layer 700 to the substrate layer 500, effectively preventing delamination between the two layers. It also resists a certain degree of external impact and wear, ensuring the integrity of the nano-water display chip anti-counterfeiting label during transportation, storage, and actual application, thus extending its service life. Furthermore, if counterfeiters forcibly tear off the communication layer 700, the strong adhesive will preferentially disrupt the sensing circuit of the detection antenna 730, triggering a status code change in the NFC chip 710, further enhancing the anti-counterfeiting capability of the nano-water display chip anti-counterfeiting label. The first adhesive layer 600 can be made of a suitable adhesive material to ensure it does not interfere with electronic components such as the RF antenna 720 or the NFC chip 710, thereby guaranteeing the effective operation of the communication layer 700 and maintaining stable wireless communication capabilities.

[0046] In other embodiments, the communication layer 700 may be sandwiched between the first adhesive layer 600 and the substrate layer 500, with the first adhesive layer 600 covering the communication layer 700 and bonded to the substrate layer 500 through its edges.

[0047] In one implementation, please refer to Figure 1 The nano water display chip anti-counterfeiting label also includes a second adhesive layer 800, which is bonded to the side of the communication layer 700 away from the substrate layer 500.

[0048] The second adhesive layer 800 is located on the side of the communication layer 700 opposite to the substrate layer 500, and is used to firmly adhere the nano-water indicator chip anti-counterfeiting label to the target product or packaging. Unlike the first adhesive layer 600, the second adhesive layer 800 focuses more on adaptability to the external environment, such as good adhesion to various material surfaces (e.g., paper, plastic, metal), as well as temperature resistance and anti-aging properties. The second adhesive layer 800 ensures that the nano-water indicator chip anti-counterfeiting label is stably adhered to the product or packaging it is applied to for a long time, and is not easy to fall off or peel off, especially under various environmental conditions encountered during transportation, storage, and sales. In addition to its adhesive function, the second adhesive layer 800 also provides a physical barrier for the communication layer 700, reducing the potential damage caused by external factors (e.g., dust, moisture, mechanical scratches). The second adhesive layer 800 can be made of an adhesive material that does not affect wireless signal transmission, ensuring that communication between the NFC chip 710 and external devices remains smooth even when attached.

[0049] In one implementation, please refer to Figure 1 The second adhesive layer 800 is a pressure-sensitive adhesive.

[0050] Pressure-sensitive adhesives do not require heating, solvents, or moisture activation; they achieve instant bonding with just a light pressure, greatly simplifying label application and eliminating the need for additional equipment or waiting time. Pressure-sensitive adhesives possess excellent initial tack and holding power, and maintain stable performance over a wide temperature range. They adhere well to various material surfaces, such as paper, plastics, metals, and glass, providing a wide range of applications for nano-water indicator chip anti-counterfeiting labels.

[0051] In other embodiments, the second adhesive layer 800 may also be a moisture-curing adhesive, a light-curing adhesive, or the like.

[0052] In one implementation, please refer to Figure 1 The nano water display chip anti-counterfeiting label also includes a release paper layer 900, which is bonded to the substrate layer 500 by a second adhesive layer 800.

[0053] Release paper layer 900 is a special paper or film material coated with a release agent. It has low surface energy, making it difficult for the second adhesive layer 800 to adhere firmly, thus allowing for easy peeling. In its factory or transport condition, release paper layer 900 adheres to the surface of the second adhesive layer 800, providing protection. When needed, the release paper is peeled off, exposing the second adhesive layer 800, allowing the anti-counterfeiting label unit 1000 (including at least the water-based film layer 200, the first printing layer 400, the substrate layer 500, the communication layer 700, and the second adhesive layer 800) to be applied to the target object's surface. Release paper layer 900 effectively isolates the second adhesive layer 800 from the external environment, ensuring it remains clean and highly tacky before use, thus guaranteeing good adhesive performance of the anti-counterfeiting label unit 1000 during long-term storage or transportation. The design of release paper layer 900 also makes labeling intuitive, convenient, and efficient.

[0054] In one implementation, please refer to Figure 1 and Figure 3 The orthographic projection of the substrate layer 500 along a direction perpendicular to the surface falls into the release paper layer 900, and the outline of the orthographic projection of the substrate layer 500 has a gap with the edge of the release paper layer 900.

[0055] Orthographic projection refers to projecting the outline of the substrate layer 500 onto the plane containing the release paper layer 900 when viewed from a direction perpendicular to the surface of the nano-water display chip anti-counterfeiting label. Orthographic projection falling within the release paper layer 900 means that the projection of the substrate layer 500 (and all functional layers thereon) is completely contained within the release paper layer 900, and a certain safety distance is maintained between the projected outline of the substrate layer 500 and the outer edge of the release paper layer 900; that is, the release paper layer 900 is larger than the substrate layer 500.

[0056] The second adhesive layer 800 is located below the substrate layer 500. Near the edge, it may experience slight creep or overflow due to pressure or temperature changes. A gap is maintained between the outline of the substrate layer 500 (projected onto the surface) and the edge of the release paper layer 900 to accommodate minor overflow of the second adhesive layer 800, preventing contamination or edge adhesion during production and use. Furthermore, this gap facilitates stable gripping and smooth peeling of the release paper layer 900 by fingers or mechanical grippers, improving labeling efficiency and reducing operational errors, making it particularly suitable for high-speed automated labeling lines.

[0057] In other embodiments, the outline of the orthographic projection of the substrate layer 500 may be flush with the edge of the release paper layer 900.

[0058] In one implementation, please refer to Figure 3 and Figure 4A water-display film layer 200, a first printing layer 400, a substrate layer 500, a communication layer 700, and a second adhesive layer 800 are stacked in sequence to form an anti-counterfeiting label unit 1000. Multiple anti-counterfeiting label units 1000 are disposed on the same release paper layer 900 through their respective second adhesive layers 800 to form a nano water-display chip anti-counterfeiting label array.

[0059] Multiple anti-counterfeiting label units 1000 are arranged in an array and adhered to the same continuous release paper via their respective second adhesive layers 800. Micro-slits, perforated lines, or gaps can be provided between each anti-counterfeiting label unit 1000 to facilitate subsequent individual peeling and use. The various functional layers of the multiple anti-counterfeiting label units 1000 can be completed on the roll material in one go through processes such as continuous coating, printing, lamination, and die-cutting. The parallel manufacturing of multiple anti-counterfeiting label units 1000 significantly improves production speed and capacity, reducing the processing steps and equipment changeover time for individual nano-water indicator chip anti-counterfeiting labels. Furthermore, integrating a large number of anti-counterfeiting label units 1000 onto a single release paper reduces the risk of confusion from bulk labels and allows for packaging in rolls or standard-sized sheets, saving space and facilitating transportation and storage.

[0060] In other embodiments, only one anti-counterfeiting label unit 1000 may be provided on a single release paper layer 900.

[0061] In one implementation, please refer to Figure 3 The anti-counterfeiting label unit 1000 also includes a first adhesive layer 600 disposed between the substrate layer 500 and the communication layer 700, a second printing layer 100 disposed on the side of the water reveal film layer 200 opposite to the first printing layer 400, and a third adhesive layer 300 disposed between the water reveal film layer 200 and the second printing layer 100.

[0062] In one implementation, please refer to Figure 1 The anti-counterfeiting label for the nano water display chip also includes a second printing layer 100, which covers the side of the water display film layer 200 away from the first printing layer 400, and has visible marking information on it.

[0063] The second printing layer 100 contains visible information that can be used to provide product information to users. This visible information can include brand logos, product names, indicative text (such as water-activated displays or verification via water), graphics, security threads, microtext, and other auxiliary anti-counterfeiting elements. The second printing layer 100 can be printed in high-quality color, giving the label excellent visual appeal. Printing brand logos and maintaining a unified design style enhances the overall aesthetics of the product packaging, helping consumers quickly identify genuine products and build brand trust. As the outermost layer, the second printing layer 100 resists minor scratches and friction, preventing damage to the water-activated film layer 200, protecting the internal functional layers, enhancing durability, improving the wear resistance of the nano-water-activated chip anti-counterfeiting label, and ensuring the long-term effectiveness of the water-activated display function.

[0064] In other embodiments, the second printing layer 100 may also be text or patterns directly printed on the water-based film layer 200 according to user requirements.

[0065] In one implementation, please refer to Figure 1 The nano water display chip anti-counterfeiting label also includes a third adhesive layer 300, which is bonded between the water display film layer 200 and the first printing layer 400.

[0066] The third adhesive layer 300 is bonded between the water-based display film layer 200 and the first printed layer 400, enhancing the interfacial adhesion between the two. This ensures a tight bond between the first printed layer 400 and the water-based display film layer 200, preventing delamination, bubbling, or peeling, and improving the long-term reliability of the label. The third adhesive layer 300 must be transparent so as not to affect the display effect of the first printed layer 400, and it must not chemically react with the water-based display material. The third adhesive layer 300 can act as a buffer during coating or printing, preventing solvents in the printing ink from directly contacting the water-based display film layer 200, which could cause swelling, discoloration, or functional failure.

[0067] In one embodiment, the substrate layer 500 is made of fragile paper.

[0068] Fragile paper is brittle and has low strength; it breaks easily with slight bending, stretching, or peeling. Its tensile strength is far lower than that of adhesives, meaning it cannot be completely removed after application and cannot be reused for counterfeiting. When a nano-water indicator chip anti-counterfeiting label is affixed to a product surface, if someone attempts to peel it off, transfer it, or reuse it, the fragile paper substrate layer 500 will cause irreversible breakage, fragmentation, or delamination during the peeling process, rendering the label ineffective. This achieves a physical damage-based anti-counterfeiting logic, enhancing security. The fragile paper is compatible with the anti-counterfeiting linkage of the communication layer 700. Breakage of the fragile paper often simultaneously disrupts the sensing circuit formed by the NFC chip 710 and the detection antenna 730, triggering a status code change. The substrate layer 500 can be made of aluminum foil fragile paper, aluminized paper, fiber tear paper, microporous paper, etc.

[0069] In other embodiments, the substrate layer 500 can be made of one or more of the following: self-adhesive materials, writing paper materials, and film materials. The substrate layer 500 made of self-adhesive materials is strong and durable; writing paper materials are readily available and inexpensive, making the substrate layer 500 easier for users to mark; film materials are thinner, more aesthetically pleasing, and more durable. The material of the substrate layer 500 can be selected according to requirements.

[0070] In one embodiment, the water-reflective membrane layer 200 is a porous membrane.

[0071] The water-display film layer 200 is a porous membrane, a nanoscale microporous membrane with pore sizes between 50 nanometers and 900 nanometers. This porous membrane allows for more rapid absorption and diffusion of moisture throughout the entire water-display film layer 200, thus accelerating the transition from a covered state to a transparent state. Because moisture can permeate evenly through the pores, it avoids the problem of localized areas developing too quickly or too slowly, ensuring that the information in the first printing layer 400 is clearly and completely presented. Simultaneously, it maintains sufficient structural stability to prevent the water-display film layer 200 from easily breaking. The porous membrane has good air permeability; its porous structure allows air circulation, reducing the expansion and contraction effects caused by humidity changes. This helps maintain the stability of the internal environment of the nano-water-display chip anti-counterfeiting label, preventing mold or other damage caused by moisture accumulation and extending the lifespan of the nano-water-display chip anti-counterfeiting label.

[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
