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 aerosols. Currently, electronic atomizing devices are gradually incorporating NFC (Near Field Communication) technology for product identification and atomizer anti-counterfeiting.

[0003] However, traditional electronic atomizing devices lack effective atomizer authentication mechanisms, making it difficult to avoid security risks caused by incompatible or inferior atomizers.

[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 support, wherein the support is disposed within the tube;

[0010] An antenna, located at one end of the bracket near the connector and used for exchanging information with the near-field communication tag; and

[0011] The main control board is located inside the tube and on the side of the bracket away from the insertion interface. The main control board is electrically connected to the battery and the antenna. The main control board can receive encrypted information from the near-field communication tag through the antenna to verify the atomizer.

[0012] The aforementioned power supply device achieves at least the following beneficial effects: By integrating the antenna into the end of the bracket near the insertion interface, placing it directly adjacent to the near-field communication tag inserted into the atomizer, this close-coupled design significantly improves RF signal transmission efficiency and communication stability. The main control board can quickly and accurately receive encrypted verification information from the near-field communication tag through this antenna, achieving genuine / counterfeit atomizer identification while maintaining the core power supply function. In particular, this antenna system occupies only a minimal space at the end of the bracket near the insertion interface; its compact structure avoids interference with critical functional areas such as the airflow channel within the tube, while ensuring the reliability of near-field communication, ultimately achieving a high degree of functional module integration with zero spatial redundancy.

[0013] In some embodiments, the antenna includes a winding portion and a first end and a second end connected to both ends of the winding portion. A limiting groove is formed on the outer circumferential surface of the bracket, and the winding portion wraps multiple times within the limiting groove along the circumference of the bracket. By wrapping the antenna winding portion around the bracket within the limiting groove, a compact layout and precise positioning of the antenna structure are achieved. The limiting groove provides physical constraint on the multiple wraps of the winding portion, ensuring a stable connection between the antenna and the bracket, and optimizing the electromagnetic field coverage through circumferential distribution. The connection design of the first and second ends extending from the winding portion maintains the electrical integrity of the antenna circuit within a limited space. At the same time, this wraparound structure makes the overall thickness of the antenna flush with the outer contour of the bracket, avoiding additional space occupation inside the tube. This integrated wiring method further improves the space utilization rate inside the power supply device while ensuring near-field communication performance.

[0014] In some embodiments, the limiting groove extends in a ring shape along the circumference of the bracket. By designing the limiting groove as a ring structure extending circumferentially along the bracket, the winding portion of the antenna can uniformly surround the outer surface of the bracket, forming a stable ring-shaped electromagnetic field distribution. This ring-shaped limiting groove provides a continuous and consistent constraint space for the winding portion, ensuring a more secure fixation of the antenna on the bracket, while optimizing the symmetry of the antenna coil and the uniformity of signal coverage. The ring layout also ensures that each loop of the winding portion has the same path length, which helps maintain the consistency of the electrical characteristics of the antenna loop, thereby improving the stability of near-field communication. Furthermore, this design allows the antenna to maximize the effective winding area without increasing the radial dimension of the bracket, further improving space utilization efficiency.

[0015] In some embodiments, the power supply device further includes a sealing element fitted within the limiting groove. The sealing element covers the winding portion and seals against the inner wall of the tube. By providing a sealing element within the limiting groove, the antenna winding portion can be effectively covered and protected from external environmental interference or mechanical damage. Simultaneously, the tight seal between the sealing element and the inner wall of the tube achieves a sealed protection of the internal space of the power supply device. This effectively prevents condensate, aerosol matrix leaking from the atomizer, and external liquids from seeping into the limiting groove, avoiding corrosion of the antenna winding portion within the limiting groove. It also buffers mechanical vibrations between components, preventing wear of the winding portion due to long-term use. Furthermore, the elastic compression characteristics of the sealing element allow it to fully seal and fill the assembly gap between the support and the winding portion within a limited space, while maintaining uniform pressure on the winding portion. This ensures the overall stability of the antenna structure without affecting its electromagnetic induction performance, thus maintaining stable near-field communication functionality even in harsh operating environments.

[0016] In some embodiments, the antenna includes a winding portion and a first end and a second end connected to both ends of the winding portion. The winding portion wraps multiple times around the periphery of the end face of the bracket facing the connector, and the first and second ends extend away from the connector and are electrically connected to the main control board. By wrapping the antenna winding portion around the periphery of the end face of the bracket facing the connector, the antenna can make full use of the space at the end of the bracket for a compact layout, while avoiding interference with other components inside the tube. The multi-turn winding design increases the effective sensing area of ​​the antenna, which is beneficial for enhancing the signal strength and stability of near-field communication.

[0017] In some embodiments, the power supply device further includes a conductive element passing through the bracket, one end of which is electrically connected to the main control board, and the other end of which is electrically connected to the atomizer.

[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 and the air inlet of the atomizer form a communicating airflow channel, enabling the sensing element to monitor changes in negative pressure or airflow disturbances generated during inhalation in real time. When a dynamic airflow characteristic meeting a preset threshold is detected, the sensing element immediately sends a trigger signal to the main control board, which then activates the conductive component to precisely supply power to the atomizer.

[0019] 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.

[0020] In some embodiments, the antenna is a laser-engraved antenna or a printed antenna mounted on the bracket. The antenna can be directly integrated onto the bracket using laser engraving or printing methods. By directly laser-engraving or printing conductive material onto the bracket to form the antenna pattern, not only is the assembly process of traditional standalone antennas eliminated, but the integrated structure of the antenna and bracket is also achieved. Laser-engraved antennas form precise conductive lines on the bracket using laser etching technology, resulting in high precision and good signal transmission performance; printed antennas use conductive ink printing technology, offering advantages such as low cost and mass production. Both of these integrated antenna solutions effectively reduce internal space occupation while ensuring stable transmission of wireless communication signals.

[0021] In some embodiments, the power supply device further includes a battery disposed within the tube body, the battery being located on the side of the main control board facing away from the connector and 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 body axis. This structural design not only makes full use of the longitudinal space inside the tube body, 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.

[0022] 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.

[0023] Because the aforementioned electronic atomizing device includes the power supply device described in any of the above embodiments, it can achieve at least the following beneficial effects: The power supply device integrates the antenna into the end of the bracket near the connector, placing it directly adjacent to the near-field communication tag inserted into the atomizer. This close-range coupling design significantly improves the efficiency of radio frequency signal transmission and communication stability. The main control board can quickly and accurately receive the encrypted verification information from the near-field communication tag through this antenna, achieving genuine / counterfeit atomizer identification while maintaining the core power supply function. In particular, this antenna system occupies only a tiny space at the end of the bracket near the connector. Its compact structure avoids interference with key functional areas such as the airflow channel within the tube and ensures the reliability of near-field communication, ultimately achieving a high degree of functional module integration with zero spatial redundancy.

[0024] 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.

[0025] 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.

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.

[0040] Please see Figures 1 to 9 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 bracket 520, an antenna 300, and a main control board 200. The bracket 520 is disposed inside the tube body 100. One end of the tube body 100 has a connector 110 for inserting the atomizer 12 with a near-field communication tag 640. The antenna 300 is disposed at the end of the bracket 520 near the connector 110 and is used to exchange information with the near-field communication tag 640. The battery 560 and the main control board 200 are disposed inside the tube body 100, and the main control board 200 is located on the side of the bracket 520 away from the connector 110. The main control board 200 is electrically connected to the battery 560 and the antenna 300. The main control board 200 can receive encrypted information from the near-field communication tag 640 through the antenna 300 to verify the atomizer 12. The atomizer 12 can atomize the aerosol generating matrix to form an aerosol. The aerosol generating matrix can refer to a material that can be atomized under certain conditions to provide aerosol components.

[0041] The aforementioned power supply device 11 can achieve at least the following beneficial effects: such as Figure 5 , Figure 8 and Figure 9 As shown, by integrating the antenna 300 into the end of the bracket 520 near the insertion interface 110, its spatial layout is directly adjacent to the near-field communication tag 640 into which the atomizer 12 is inserted. This close-range coupling design significantly improves the efficiency of radio frequency signal transmission and communication stability. The main control board 200 can quickly and accurately receive the encrypted verification information of the near-field communication tag 640 through the antenna 300, achieving the identification of the authenticity of the atomizer 12 while maintaining the core power supply function. In particular, the antenna 300 system occupies only a tiny space at one end of the bracket 520 near the insertion interface 110. Its compact structure avoids interference with key functional areas such as the airflow channel inside the tube 100, while ensuring the reliability of near-field communication, ultimately achieving a high degree of integration of functional modules with zero space redundancy.

[0042] like Figure 5As shown, in some embodiments, the antenna 300 includes a winding portion 330 and a first end 310 and a second end 320 connected to both ends of the winding portion 330. A limiting groove 521 is formed on the outer circumferential surface of the bracket 520, and the winding portion 330 wraps multiple times within the limiting groove 521 along the circumference of the bracket 520. By encircling the winding portion 330 of the antenna 300 within the limiting groove 521 along the circumference of the bracket 520, a compact layout and precise positioning of the antenna 300 structure are achieved. The limiting groove 521 provides physical constraint on the multiple turns of the winding portion 330, ensuring a stable connection between the antenna 300 and the bracket 520, and optimizing the electromagnetic field coverage range through circumferential distribution. The connection design, where the first end 310 and the second end 320 extend from the winding portion 330, maintains the electrical integrity of the antenna 300 circuit within a limited space. Simultaneously, this wraparound structure ensures that the overall thickness of the antenna 300 is flush with the outer contour of the support 520, avoiding additional space occupation within the tube 100. This integrated wiring method further improves the space utilization within the power supply device 11 while maintaining near-field communication performance.

[0043] like Figure 5 As shown, in some embodiments, the limiting groove 521 extends in a ring shape along the circumference of the bracket 520. By designing the limiting groove 521 as a ring structure extending circumferentially along the bracket 520, the winding portion 330 of the antenna 300 can uniformly surround the outer surface of the bracket 520, forming a stable ring-shaped electromagnetic field distribution. This ring-shaped limiting groove 521 provides a continuous and consistent constraint space for the winding portion 330, ensuring that the antenna 300 is more firmly fixed on the bracket 520, while optimizing the symmetry and signal coverage uniformity of the antenna 300 coil. The ring layout also makes the length of each loop of the winding portion 330 the same, which helps to maintain the consistency of the electrical characteristics of the antenna 300 loop, thereby improving the stability of near-field communication. In addition, this design allows the antenna 300 to maximize the effective winding area without increasing the radial dimension of the bracket 520, further improving space utilization efficiency.

[0044] like Figure 5 and Figure 6As shown, in some embodiments, the power supply device 11 further includes a sealing member 510 sleeved within the limiting groove 521. The sealing member 510 covers the winding portion 330 and seals against the inner wall of the tube body 100. By providing the sealing member 510 within the limiting groove 521, not only can the winding portion 330 of the antenna 300 be effectively covered and protected, preventing it from being interfered with by the external environment or mechanical damage, but the tight abutment between the sealing member 510 and the inner wall of the tube body 100 also achieves the sealing protection of the internal space of the power supply device 11. This effectively prevents condensate, some aerosol generation matrix leaking from the atomizer 12, and external liquids from seeping into the limiting groove 521, avoiding corrosion of the winding portion 330 of the antenna 300 within the limiting groove 521, and also buffering mechanical vibration between components, preventing wear of the winding portion 330 caused by long-term use. Meanwhile, the elastic compression characteristics of the seal 510 enable it to fully seal the assembly gap between the filler bracket 520 and the winding part 330 within a limited space, while maintaining uniform pressure on the winding part 330. This ensures the overall stability of the antenna 300 structure without affecting its electromagnetic induction performance, thus maintaining stable near-field communication function even in harsh operating environments.

[0045] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the antenna 300 includes a winding portion 330 and a first end 310 and a second end 320 connected to both ends of the winding portion 330. The winding portion 330 wraps around the periphery of the end face of the bracket 520 facing the connector 110 multiple times along the circumference of the bracket. The first end 310 and the second end 320 extend away from the connector 110 and are electrically connected to the main control board 200. By surrounding the winding portion 330 of the antenna 300 around the periphery of the end face of the bracket 520 facing the connector 110, the antenna 300 can make full use of the space at the end of the bracket 520 for a compact layout, while avoiding interference with other components inside the tube 100. The multi-turn winding design of the winding portion 330 increases the effective sensing area of ​​the antenna 300, which is beneficial for enhancing the signal strength and stability of near-field communication.

[0046] like Figure 4 and Figure 6 As shown, in some embodiments, the power supply device 11 further includes a conductive element 530 passing through the bracket 520, one end of the conductive element 530 being electrically connected to the main control board 200, and the other end of the conductive element 530 being electrically connected to the atomizer 12.

[0047] like Figure 4As 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 200. 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 200 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 hole 522 on the bracket 520 forms an airflow channel communicating with the air inlet of the atomizer 12, enabling the sensing element 550 to monitor negative pressure changes or airflow disturbances generated during user inhalation in real time. When a dynamic airflow characteristic meeting a preset threshold is detected, the sensing element 550 immediately sends a trigger signal to the main control board 200, which then activates the conductive element 530 to precisely supply power to the atomizer 12.

[0048] 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.

[0049] like Figure 5 As shown, in some embodiments, the antenna 300 can be a separate wire wound around the bracket 520. In other embodiments, the antenna 300 can be a laser-engraved antenna 300 or a printed antenna 300 mounted on the bracket 520. The antenna 300 can be directly integrated onto the bracket 520 using laser engraving or printing. By directly laser-engraving or printing conductive material onto the bracket 520 to form the antenna 300 pattern, not only is the assembly process of the traditional independent antenna 300 eliminated, but the integrated structure of the antenna 300 and the bracket 520 is also achieved. The laser-engraved antenna 300 forms precise conductive lines on the bracket 520 through laser etching, resulting in high precision and good signal transmission performance; the printed antenna 300 uses conductive ink printing technology, offering advantages such as low cost and mass production. Both of these integrated antenna 300 solutions effectively reduce internal space occupation while ensuring stable transmission of wireless communication signals.

[0050] like Figure 4As shown, in some embodiments, the power supply device 11 further includes a battery 560 disposed within the tube body 100. The battery 560 is located on the side of the main control board 200 facing away from the connector 110 and is electrically connected to the main control board 200. This can be considered as arranging the battery 560 below the main control board 200, forming a compact stacked structure along the axial direction of the tube body 100. This structural design not only makes full use of the longitudinal space inside the tube body 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 200 and the battery 560. This layout meets the miniaturization requirements of the electronic atomizing device 10 while ensuring the stability and safety of the power system, providing a continuous and reliable energy supply for the atomizer 12.

[0051] In addition, such as Figure 1 and Figure 2 As shown, 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.

[0052] Since the aforementioned 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 integrates the antenna 300 into the end of the bracket 520 near the insertion interface 110, making it spatially adjacent to the near-field communication tag 640 into which the atomizer 12 is inserted. This close-range coupling design significantly improves the efficiency of radio frequency signal transmission and communication stability. The main control board 200 can quickly and accurately receive the encrypted verification information of the near-field communication tag 640 through the antenna 300, achieving genuine / counterfeit identification of the atomizer 12 while maintaining the core power supply function. In particular, the antenna 300 system occupies only a very small space at one end of the bracket 520 near the insertion interface 110. Its compact structure avoids interference with key functional areas such as the airflow channel inside the tube 100, while ensuring the reliability of near-field communication, ultimately achieving a high degree of integration of functional modules with zero spatial redundancy.

[0053] like Figure 3 and Figure 4As 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.

[0054] like Figure 3 and Figure 4 As 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.

[0055] like Figure 10As 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.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
