Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to a power supply device and an electronic atomization device. Background Technology

[0002] An electronic atomizing device is a device used to generate an aerosol. Currently, near-field communication (NFC) technology is being gradually introduced into electronic atomizing devices for product identification and atomizer anti-counterfeiting. However, there are still relatively few electronic cigarette products on the market that utilize NFC technology, and these are mainly used in devices with plastic casings.

[0003] However, traditional near-field communication technology solutions have large antenna sizes, making them difficult to directly apply to miniaturized electronic atomization devices. If traditional FPC technology solutions are forcibly adopted in electronic atomization devices, it will not only result in excessively large device sizes, but also encroach on the space of the original structural components such as the air passage and atomization components, potentially affecting normal gas flow inside the electronic atomization device and impacting stable near-field communication.

[0004] The above information disclosed in the background art of this application is only for understanding the background of the concept of this application, and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a power supply device and an electronic atomization device to address the above problems.

[0006] This application provides a power supply device for supplying power to an atomizer, the power supply device comprising:

[0007] The tube body has an interface at one end for inserting an atomizer with a near-field communication tag.

[0008] A battery, wherein the battery is disposed within the tube;

[0009] A mounting plate, wherein the mounting plate is disposed within the tube and has a first side and a second side facing opposite to each other, the first side facing the insertion interface; and

[0010] An antenna electrically connected to the battery and used for exchanging information with the near-field communication tag, at least a portion of which is located on the first surface.

[0011] The aforementioned power supply device can achieve at least the following beneficial effects: by distributing at least a portion of the antennas on the first surface of the mounting plate, that is, by utilizing the spatial dimension of the mounting plate's thickness direction to arrange the antennas on the first surface of the mounting plate, the area of ​​the mounting plate where the antennas are set is greatly reduced, the overall structure is more compact, the space utilization rate is significantly improved and the size of the mounting plate is reduced. Under the premise of ensuring a compact structure, reliable reception of the near-field communication tag of the atomizer and rapid verification of the authenticity of the atomizer are achieved, thereby determining whether to supply power to the atomizer.

[0012] In some embodiments, a portion of the antenna is disposed on the first surface, and another portion of the antenna extends to the second surface. By distributing the antennas on the first and second surfaces of the mounting plate opposite to each other, i.e., by implementing a double-sided antenna layout on the mounting plate, the area of ​​the mounting plate with antennas on one side is significantly reduced. This avoids the problem of needing to increase the area to expand the antenna wiring range to increase the induction intensity in traditional solutions, resulting in a more compact overall structure, significantly improving space utilization and reducing the size of the mounting plate.

[0013] In some embodiments, the power supply device further includes a first electrode, a second electrode, and a main control board disposed within the tube. The main control board is located on the side of the mounting plate away from the connector. One end of the first electrode is electrically connected to one end of the antenna, and the other end of the first electrode is electrically connected to the main control board. One end of the second electrode is electrically connected to the other end of the antenna, and the other end of the second electrode is electrically connected to the main control board. The main control board can receive encrypted information from the near-field communication tag via the antenna to verify the atomizer. The main control board, through the first and second electrodes and connecting to both ends of the antenna, constructs a complete signal transmission path, enabling it to efficiently receive encrypted information from the atomizer's near-field communication tag via the antenna to verify the authenticity of the atomizer. This anti-counterfeiting verification mechanism achieves product traceability through hardware-level encrypted communication, effectively preventing the illegal use of compatible accessories while ensuring power supply safety, thus improving the overall system's security and controllability.

[0014] In some embodiments, the power supply device further includes a bracket disposed within the tube body and a conductive element passing through the bracket. The main control board is disposed on the side of the bracket facing away from the mounting plate. The first electrode and the second electrode pass through the bracket. The mounting plate is annular and has a clearance hole in the middle that penetrates the first and second surfaces. One end of the conductive element is electrically connected to the main control board, and the other end of the conductive element passes through the clearance hole for electrical connection with the atomizer. The introduction of the bracket enables the main control board and the mounting plate to be stacked and fixed. This layered layout design achieves spatial isolation between the mounting plate and the main control board, ensures high efficiency of electrical connection, and provides precise positioning support for the electrodes and conductive elements, making the overall structure more compact and reliable. This embodiment further optimizes the spatial arrangement and control utilization of the power supply device through the adaptable design of the annular mounting plate and the bracket. The clearance hole in the center of the ring-shaped mounting plate provides a through channel for the conductive component, enabling it to be electrically connected to the atomizer. It also allows for a relatively reasonable distance between the conductive component and the antenna on the mounting plate to form physical isolation and avoid signal interference.

[0015] In some embodiments, the power supply device further includes a top cover that covers the first surface of the mounting plate. The mounting plate is sandwiched between the top cover and the bracket. The top cover has a through hole communicating with the clearance hole, allowing the conductive component to pass through for electrical connection with the atomizer. The top cover covering the first surface of the mounting plate securely clamps and encapsulates the annular mounting plate between the top cover and the bracket. This design not only provides physical protection for the mounting plate, effectively preventing impact damage during daily use, but also blocks corrosion from condensate, aerosol matrix leaking from the atomizer, and external liquids on the mounting plate and its antenna, significantly improving its service life.

[0016] In some embodiments, either the top cover or the bracket has a protruding insertion portion, and the other has a recessed insertion portion. The protruding insertion portion passes through the clearance hole and inserts into the recessed insertion portion to secure the top cover to the bracket. The precise fit between the protruding insertion portion and the recessed insertion portion enables tool-less, rapid assembly of the top cover and bracket, eliminating the need for additional fasteners. This reduces production costs, facilitates subsequent maintenance and disassembly, and ensures the positioning accuracy of the mounting plate in the clamped state. The design of the protruding insertion portion passing through the clearance hole avoids the risk of displacement of the mounting plate during assembly, effectively improving the stability of the overall structure.

[0017] In some embodiments, the mounting plate has a first electrical connection hole and a second electrical connection hole. One end of the antenna extends into the first electrical connection hole, and the other end of the antenna extends into the second electrical connection hole. One end of the first electrode is inserted into the first electrical connection hole to electrically connect with one end of the antenna, and one end of the second electrode is inserted into the second electrical connection hole to electrically connect with the other end of the antenna. This plug-in connection scheme not only simplifies the assembly process but also ensures long-term connection reliability and signal transmission stability through the interlocking of the electrodes and electrical connection holes, achieving efficient and precise docking between the antenna and the electrodes.

[0018] In some embodiments, the power supply device further includes a sensing element disposed on the bracket and electrically connected to the main control board. The bracket has a sensing hole that communicates with the air inlet of the atomizer. The sensing element sends a sensing signal to the main control board when a sufficient change in airflow or pressure is detected at the sensing hole, thereby driving the conductive component to supply power to the atomizer. The sensing hole on the bracket can communicate with the air inlet of the atomizer through a clearance hole, forming a complete airflow detection path. This ensures the synchronous transmission of airflow changes, enabling the sensing element to quickly respond to the user's inhalation action and transmit the detection signal to the main control board in real time.

[0019] In some embodiments, the battery is located on the side of the main control board away from the connector and is electrically connected to the main control board. This can be considered as arranging the battery below the main control board, forming a compact stacked structure along the tube's axial direction. This structural design not only makes full use of the longitudinal space inside the tube, making the overall structure more slender, but also effectively reduces the impact of circuit heat generation on the battery through physical isolation between the main control board and the battery. This layout meets the miniaturization requirements of electronic atomization devices while ensuring the stability and safety of the power system, providing a continuous and reliable energy supply for the atomizer.

[0020] In some embodiments, the power supply device further includes a magnetic element disposed on the side of the bracket facing the connector, which is magnetically connected to the atomizer when the atomizer is inserted from the connector.

[0021] In some embodiments, the mounting plate has through-holes penetrating the first and second surfaces, and the antenna extends from the first surface through these through-holes to the second surface. The antenna's extension from the first surface to the second surface via these through-holes forms a three-dimensional conductive path, effectively extending the antenna path length within the limited area of ​​the mounting plate and significantly improving the signal strength and stability of near-field communication. This structure breaks through the layout limitations of traditional planar antennas, maintaining the neatness of the mounting plate assembly while improving the antenna system's shock resistance and environmental adaptability through integrated wiring within the board. This three-dimensional wiring scheme is particularly suitable for electronic atomization devices with high space utilization requirements, ensuring the reliability of anti-counterfeiting verification functions while providing an effective technical path for product miniaturization design.

[0022] In some embodiments, a wiring groove is formed along the edge of the mounting plate, through which the antenna extends from the first surface to the second surface. The antenna extending from the first surface to the second surface via the wiring groove forms a three-dimensional conductive path, effectively extending the antenna path length within the limited area of ​​the mounting plate and significantly improving the signal strength and stability of near-field communication. This structure breaks through the layout limitations of traditional planar antennas, maintaining the neatness of the mounting plate assembly while improving the antenna system's shock resistance and environmental adaptability through integrated wiring within the plate. This three-dimensional wiring scheme is particularly suitable for electronic atomization devices with high space utilization requirements, ensuring the reliability of anti-counterfeiting verification functions while providing an effective technical path for product miniaturization design.

[0023] This application also provides an electronic atomizing device, which includes an atomizer with a near-field communication tag and a power supply device as described in any of the above embodiments.

[0024] Since the above-mentioned electronic atomizing device includes the power supply device described in any of the above embodiments, the electronic atomizing device can also achieve at least the following beneficial effects: the power supply device of the electronic atomizing device distributes at least part of the antenna on the first surface of the mounting plate, that is, it utilizes the spatial dimension of the thickness direction of the mounting plate to arrange the antenna on the first surface of the mounting plate, which greatly reduces the area of ​​the mounting plate where the antenna is set, making the overall structure more compact, significantly improving the space utilization rate and reducing the size of the mounting plate. Under the premise of ensuring a compact structure, it realizes reliable reception of the near-field communication tag of the atomizer and rapid verification of the authenticity of the atomizer, thereby determining whether to supply power to the atomizer.

[0025] In some embodiments, the atomizer includes a housing, a near-field communication tag, an atomizing component disposed within the housing, and a base disposed at the bottom of the housing. The base has a mounting slot, and the near-field communication tag is disposed within the mounting slot. By integrating the near-field communication tag into the mounting slot of the base, the compactness of the atomizer's overall structure is maintained, while ensuring precise positioning and stability of the near-field communication tag, preventing displacement during transportation or use from affecting communication reliability. Simultaneously, the built-in design enhances anti-counterfeiting concealment, effectively preventing the tag from being directly observed or tampered with, thus improving anti-counterfeiting security. Furthermore, the mounting slot structure, combined with a sealing design, prevents the intrusion of foreign objects, extending the lifespan of the near-field communication tag. This optimizes the space utilization and overall reliability of the atomizer while ensuring anti-counterfeiting functionality.

[0026] In some embodiments, the atomizer further includes a liquid-absorbing component embedded within the mounting groove, with the near-field communication tag sandwiched between the bottom of the mounting groove and the liquid-absorbing component. This structural design integrates the liquid-absorbing component and the near-field communication tag within the same mounting groove, achieving efficient space reuse. It maintains the compactness of the atomizer while enhancing anti-counterfeiting concealment through the liquid-absorbing component's coverage of the tag, preventing direct observation or tampering. The elastic compression characteristics of the liquid-absorbing component provide a stable mounting environment for the tag, better securing it within the mounting groove and preventing displacement during vibration or insertion / removal. Simultaneously, the liquid-absorbing component absorbs condensate or aerosol leakage from the atomizer to form a matrix, protecting the tag from liquid corrosion and extending its service life. Furthermore, the bottom of the mounting groove provides a rigid positioning reference for the tag, simplifying the manufacturing process and improving production efficiency. Without affecting the original function of the liquid-absorbing component, it achieves multiple technical effects: anti-counterfeiting protection, structural stability, and process optimization.

[0040] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] Please see Figures 1 to 5 In some embodiments, this application provides a power supply device 11 for supplying power to an atomizer 12. The power supply device 11 includes a tube body 100, a battery 560, a mounting plate 200, and an antenna 300 for exchanging information with the near-field communication tag 640. The battery 560 is disposed inside the tube body 100 and electrically connected to the antenna 300. One end of the tube body 100 has a connector 110 for inserting the atomizer 12 with the near-field communication tag 640. The mounting plate 200 is disposed inside the tube body 100 and has a first surface 210 and a second surface 220 disposed opposite to each other. The first surface 210 faces the connector 110, and at least a portion of the antenna 300 is disposed on the first surface 210. The antenna 300 can be mounted on the mounting plate 200 by means of etching copper foil, electroplating filling, printing, etc.; the atomizer 12 can atomize the aerosol generating matrix to form aerosol, and the aerosol generating matrix can refer to a material that can be atomized under certain conditions to provide aerosol components.

[0042] The aforementioned power supply device 11 can achieve at least the following beneficial effects: such as Figure 7 and Figure 8 As shown, the power supply device 11 distributes at least a portion of the antennas 300 on the first surface of the mounting plate 200, that is, it utilizes the spatial dimension of the thickness direction of the mounting plate 200 to arrange the antennas 300 on the first surface 210 of the mounting plate 200. The overall structure is more compact, significantly improving space utilization and reducing the size of the mounting plate 200. Under the premise of ensuring a compact structure, it realizes reliable reception of the near-field communication tag 640 of the atomizer 12 and rapid verification of the authenticity of the atomizer 12, thereby determining whether to supply power to the atomizer 12.

[0043] like Figure 7 and Figure 8As shown, in some embodiments, one end of the antenna 300 is disposed on the first surface 210, and the other end of the antenna 300 extends to the second surface 220. By distributing the antenna 300 on the first surface 210 and the second surface 220 opposite to each other on the mounting plate 200, the spatial dimension in the thickness direction of the mounting plate 200 is utilized to perform a double-sided layout of the antenna 300 on the mounting plate 200. This significantly reduces the area of ​​the mounting plate 200 with the antenna 300 on one side, avoiding the problem in traditional solutions where the area of ​​the mounting plate 200 needs to be increased to add wiring area for the antenna 300 to increase the induction intensity. This makes the overall structure more compact, significantly improves space utilization, reduces the size of the mounting plate 200, and also achieves electromagnetic field superposition enhancement in the vertical direction, ensuring stable communication performance.

[0044] like Figure 4 and Figure 9 As shown, in some embodiments, the power supply device 11 further includes a first electrode 410, a second electrode 420, and a main control board 510 disposed within the tube body 100. The main control board 510 is disposed on the side of the mounting plate 200 away from the plug interface 110. One end of the first electrode 410 is electrically connected to one end of the antenna 300, and the other end of the first electrode 410 is electrically connected to the main control board 510. One end of the second electrode 420 is electrically connected to the other end of the antenna 300, and the other end of the second electrode 420 is electrically connected to the main control board 510. The main control board 510 can receive encrypted information from the near-field communication tag 640 through the antenna 300 to verify the atomizer 12. The main control board 510 constructs a complete signal transmission path through the first electrode 410 and the second electrode 420, connecting both ends of the antenna 300. This enables the main control board 510 to efficiently receive the encrypted information of the near-field communication tag 640 of the atomizer 12 through the antenna 300 to verify the authenticity of the atomizer 12. This anti-counterfeiting verification mechanism realizes the product traceability function through hardware-level encrypted communication, effectively preventing the illegal use of compatible accessories while ensuring power supply safety, and improving the overall system security and controllability.

[0045] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the power supply device 11 further includes a bracket 520 disposed within the tube body 100 and a conductive element 530 passing through the bracket 520. The bracket 520 is connected to the second surface 220 of the mounting plate 200. The main control board 510 is disposed on the side of the bracket 520 facing away from the mounting plate 200. The first electrode 410 and the second electrode 420 pass through the bracket 520. The mounting plate 200 is annular and has a clearance hole 230 in the middle that passes through the first surface 210 and the second surface 220. One end of the conductive element 530 is electrically connected to the main control board 510, and the other end of the conductive element 530 passes through the clearance hole 230 for electrical connection with the atomizer 12. One end of the antenna 300 is wrapped around the clearance hole 230 multiple times on the first surface 210, and the other end of the antenna 300 is wrapped around the clearance hole 230 multiple times on the second surface 220. The introduction of bracket 520 enables the stacking and fixing of main control board 510 and mounting plate 200. This layered layout design achieves spatial isolation between mounting plate 200 and main control board 510, ensures efficient electrical connection, and provides precise positioning support for electrodes and conductive components 530, making the overall structure more compact and reliable. This embodiment further optimizes the spatial arrangement and control utilization of power supply device 11 through the matching design of annular mounting plate 200 and bracket 520. The clearance hole 230 in the center of annular mounting plate 200 provides a through channel for conductive component 530, enabling conductive component 530 to be electrically connected to atomizer 12. It also allows for a relatively reasonable distance between conductive component 530 and antenna 300 on mounting plate 200 to form physical isolation and avoid signal interference. The multiple turns of antenna 300 around clearance hole 230 on both sides of mounting plate 200 not only make full use of the peripheral space of the annular structure. The magnetic field coverage is also enhanced through a double-sided layout, ensuring stable communication with the near-field communication tag 640 of the atomizer 12.

[0046] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the power supply device 11 further includes a top cover 540, which covers the first surface 210 of the mounting plate 200. The mounting plate 200 is sandwiched between the top cover 540 and the bracket 520. The top cover 540 has a through hole 542 communicating with the clearance hole 230. The through hole 542 is used for the conductive element 530 to pass through and be electrically connected to the atomizer 12. The top cover 540 covers the first surface 210 of the mounting plate 200, firmly clamping and encapsulating the annular mounting plate 200 between the top cover 540 and the bracket 520. This design not only provides physical protection for the mounting plate 200, effectively preventing bumps and damage during daily use, but also blocks condensate, aerosol generation matrix leaking from the atomizer 12, and external liquids from corroding the mounting plate 200 and the antenna 300 on it, significantly improving its service life.

[0047] like Figure 5 and Figure 6 As shown, in some embodiments, either the top cover 540 or the bracket 520 is provided with a plug-in protrusion 541, and the other is provided with a plug-in recess 521. The plug-in protrusion 541 passes through the clearance hole 230 and is inserted into the plug-in recess 521 to fix the top cover 540 and the bracket 520. Through the precise cooperation between the plug-in protrusion 541 and the plug-in recess 521, tool-free rapid assembly of the top cover 540 and the bracket 520 is achieved, eliminating the need for additional fasteners. This reduces production costs, facilitates subsequent maintenance and disassembly, and ensures the positioning accuracy of the mounting plate 200 in the clamped state. The design of the plug-in protrusion 541 passing through the clearance hole 230 avoids the risk of displacement of the mounting plate 200 during assembly, effectively improving the stability of the overall structure.

[0048] like Figure 7 and Figure 8As shown, in some embodiments, the mounting plate 200 has a first electrical connection hole 241 and a second electrical connection hole 242. One end of the antenna 300 extends into the first electrical connection hole 241, and the other end of the antenna 300 extends into the second electrical connection hole 242. One end of the first electrode 410 is inserted into the first electrical connection hole 241 to be electrically connected to one end of the antenna 300, and one end of the second electrode 420 is inserted into the second electrical connection hole 242 to be electrically connected to the other end of the antenna 300. The mounting plate 200 has a first electrical connection hole 241 and a second electrical connection hole 242. One end of the first electrode 410 is inserted into the first electrical connection hole 241 to form an electrical connection with one end of the antenna 300. At the same time, one end of the second electrode 420 is inserted into the second electrical connection hole 242 to form an electrical connection with the other end of the antenna 300. This plug-in connection scheme not only simplifies the assembly process, but also ensures the reliability of the connection during long-term use through the interlocking of the electrodes and electrical connection holes, ensuring the stability of signal transmission, and realizing efficient and precise effective docking between the antenna 300 and the electrodes.

[0049] like Figure 4 As shown, in some embodiments, the power supply device 11 further includes a sensing element 550 disposed on the bracket 520 and electrically connected to the main control board 510. The bracket 520 has a sensing hole 522 that communicates with the air inlet of the atomizer 12. The sensing element 550 sends a sensing signal to the main control board 510 when a sufficient change in airflow or air pressure is detected at the sensing hole 522, thereby driving the conductive element 530 to supply power to the atomizer 12. The sensing element may include, but is not limited to, a microphone. The sensing hole 522 on the bracket 520 communicates with the air inlet of the atomizer 12 through a clearance hole 230, forming a complete airflow detection path. This ensures the synchronous transmission of airflow changes, enabling the sensing element 550 to quickly respond to the user's inhalation action and transmit the detection signal to the main control board 510 in real time.

[0050] like Figure 4 As shown, in some embodiments, the battery 560 is located on the side of the main control board 510 away from the connector 110 and is electrically connected to the main control board 510. This can be considered as arranging the battery 560 below the main control board 510, forming a compact stacked structure along the axial direction of the tube 100. This structural design not only makes full use of the longitudinal space inside the tube 100, making the overall structure more slender, but also effectively reduces the impact of circuit heat generation on the battery 560 through the physical isolation between the main control board 510 and the battery 560. This layout meets the miniaturization requirements of the electronic atomizing device 10 and ensures the stability and safety of the power system, providing a continuous and reliable energy supply for the atomizer 12.

[0051] like Figure 4 As shown, in some embodiments, the power supply device 11 further includes a magnetic element 570, which is disposed on the side of the bracket 520 facing the insertion interface 110. When the atomizer 12 is inserted from the insertion interface 110, the magnetic element 570 can be magnetically connected to the atomizer 12.

[0052] like Figure 7 As shown, in some embodiments, the mounting plate 200 has a through-hole 243 penetrating the first surface 210 and the second surface 220, and the antenna 300 extends from the first surface 210 to the second surface 220 through the through-hole 243. The antenna 300 extends from the first surface 210 to the second surface 220 through the through-hole 243 on the mounting plate 200, forming a three-dimensional conductive path. This effectively extends the path length of the antenna 300 within the limited area of ​​the mounting plate 200, significantly improving the signal strength and stability of near-field communication. This structure breaks through the layout limitations of traditional planar antennas 300, maintaining the neatness of the mounting plate 200 assembly while improving the shock resistance and environmental adaptability of the antenna 300 system through integrated wiring within the plate. This three-dimensional wiring scheme is particularly suitable for electronic atomization devices 10 with high space utilization requirements, ensuring the reliability of anti-counterfeiting verification functions while providing an effective technical implementation path for product miniaturization design.

[0053] In some embodiments, the mounting plate 200 has a wiring groove along its edge, and the antenna 300 extends from the first surface 210 through the wiring groove to the second surface 220. The antenna 300 extends from the first surface 210 through the wiring groove along the edge of the mounting plate 200 to the second surface 220, forming a three-dimensional conductive path. This effectively extends the path length of the antenna 300 within the limited area of ​​the mounting plate 200, significantly improving the signal strength and stability of near-field communication. This structure breaks through the layout limitations of traditional planar antennas 300, maintaining the neatness of the mounting plate 200 assembly while improving the shock resistance and environmental adaptability of the antenna 300 system through integrated wiring within the plate. This three-dimensional wiring scheme is particularly suitable for electronic atomization devices 10 with high space utilization requirements, ensuring the reliability of anti-counterfeiting verification functions while providing an effective technical path for product miniaturization design.

[0054] In addition, such as Figure 1 and Figure 2 This application also provides an electronic atomizing device 10, which includes an atomizer 12 with a near-field communication tag 640 and a power supply device 11 as described in any of the above embodiments.

[0055] Since the above-mentioned electronic atomizing device 10 includes the power supply device 11 described in any of the above embodiments, the electronic atomizing device 10 can also achieve at least the following beneficial effects: The power supply device 11 of the electronic atomizing device 10 distributes the antenna 300 on the first side 210 and the second side 220 of the mounting plate 200 opposite to each other. That is, it utilizes the spatial dimension of the thickness direction of the mounting plate 200 to arrange the antenna 300 on both sides of the mounting plate 200, which greatly reduces the area of ​​the mounting plate 200 with the antenna 300 on one side. This avoids the problem in the traditional solution that the area of ​​the mounting plate 200 needs to be increased to add the wiring area of ​​the antenna 300 to increase the induction intensity. This makes the overall structure more compact, significantly improves the space utilization and reduces the size of the mounting plate 200. It can also achieve electromagnetic field superposition enhancement in the vertical direction, ensuring stable communication performance. Under the premise of ensuring a compact structure, it realizes reliable reception of the near-field communication tag 640 of the atomizer 12 and rapid verification of the authenticity of the atomizer 12, thereby determining whether to supply power to the atomizer 12.

[0056] like Figure 3 and Figure 4 As shown, in some embodiments, the atomizer 12 includes a housing 610, a near-field communication tag 640, an atomizing component 650 disposed within the housing 610, and a base 620 disposed at the bottom of the housing 610. The base 620 has a mounting groove 621, and the near-field communication tag 640 is disposed within the mounting groove 621. By integrating the near-field communication tag 640 into the mounting groove 621 of the base 620, the compactness of the overall structure of the atomizer 12 is maintained, while ensuring the precise positioning and stability of the near-field communication tag 640, avoiding displacement during transportation or use that could affect communication reliability. Simultaneously, the design of being built into the base 620 enhances anti-counterfeiting concealment, effectively preventing the tag from being directly observed or tampered with, thus improving anti-counterfeiting security. Furthermore, the mounting groove 621 structure, combined with a sealing design, can prevent the intrusion of foreign objects, extending the service life of the near-field communication tag 640. This optimizes the space utilization and overall reliability of the atomizer 12 while ensuring the anti-counterfeiting function is achieved.

[0057] like Figure 3 and Figure 4As shown, in some embodiments, the atomizer 12 further includes a liquid-absorbing component 630, which is embedded in the mounting groove 621. The near-field communication tag 640 is sandwiched between the bottom of the mounting groove 621 and the liquid-absorbing component 630. This structural design achieves efficient space reuse by integrating the liquid-absorbing component 630 and the near-field communication tag 640 into the same mounting groove 621. It maintains the compactness of the atomizer 12 while enhancing the anti-counterfeiting and concealment of the tag by covering it with the liquid-absorbing component 630, preventing the tag from being directly observed or tampered with. The liquid-absorbing component 630 may include, but is not limited to, absorbent cotton. The elastic compression characteristics of the liquid-absorbing component 630 provide a stable installation environment for the tag, better fixing the near-field communication tag 640 within the mounting groove 621 and preventing displacement during vibration or insertion / removal. Simultaneously, the liquid-absorbing component 630 can absorb condensate or aerosol leakage from the atomizer 12 to generate a matrix, protecting the tag from liquid corrosion and extending its service life. Furthermore, the bottom of the mounting groove 621 provides a rigid positioning reference for the tag, simplifying the production process and improving production efficiency. Without affecting the original function of the liquid-absorbing component 630, multiple technical effects of anti-counterfeiting protection, structural stability, and process optimization are achieved.

[0058] like Figure 10 As shown, this application also provides an atomizer anti-counterfeiting system 20, which includes a control unit 21 and a read / write circuit 22. The read / write circuit 22 can exchange signals with the antenna 300. The control unit 21 can send a data reading instruction to the near-field communication tag 640 through the read / write circuit 22 and the antenna 300. After receiving the instruction, the near-field communication tag 640 can encrypt the data and send it to the antenna 300. After receiving the data, the antenna 300 transmits the data to the read / write circuit 22. The read / write circuit 22 then decodes the data and sends the decoded data to the control unit 21. The control unit 21 can decrypt the data and confirm whether the atomizer 12 carries the correct near-field communication tag 640 based on the decrypted data, thereby confirming the authenticity of the atomizer 12 and deciding whether to supply power to the atomizer 12.
