Description

[0002] E-cigarettes are products that heat e-liquid to produce an aerosol for users to inhale. E-liquid typically contains nicotine, flavorings, and other ingredients, and is available in various flavors and nicotine concentrations. Their basic structure consists of a battery, an atomizer, and a cartridge (or e-liquid tank). With the development of smart e-cigarettes, they need to incorporate Bluetooth or Wi-Fi communication capabilities to connect to mobile applications, enabling intelligent experiences such as battery monitoring, usage records, and function adjustments. Currently, e-cigarettes need to balance compact size with stable signal, so they often use built-in flexible antennas or PCB antennas designed inside the battery module, atomizer, and other components.

[0003] In implementing the embodiments of this application, the inventors discovered that: currently, traditional antenna designs require independent antenna elements. In the limited internal space of an electronic cigarette, independent antenna elements compete with functional components such as batteries and circuit boards for valuable installation space, resulting in limited product structure design and making it difficult to achieve the ideal miniaturized design goal.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see Figure 1 and Figure 2 The electronic cigarette 100 includes a first circuit board 10, a radiation component 20, a connector 30, a second circuit board 40, a power supply component 50, an inner shell 60, an outer shell 70, a battery component 91, a cushioning foam 90, and a positioning structure (not shown).

[0027] The first circuit board 10 uses a double-sided copper-clad FR4 substrate, and a microstrip line (not shown) is disposed on the first circuit board 10. A radiating component 20 is disposed on the first circuit board 10. A connector 30 is disposed on the radiating component 20, and the connector 30 is a ring-shaped metal sheet structure. The radiating component 20 and the connector 30 constitute a radiating unit, which operates in quarter-wavelength resonance mode. The second circuit board 40 is a flexible circuit board, connected to the ground plane of the first circuit board 10 and attached to the inner shell 60. The second circuit board 40 is used to extend the ground plane of the first circuit board 10; the size of the entire ground plane system can be controlled by adjusting the length of the second circuit board 40. The power supply component 50 includes a power supply cable, and the battery component 91 is electrically connected to the first circuit board 10. The power supply component 50 transmits electrical signals to the first circuit board 10 through the power supply cable. The microstrip line receives the electrical signals transmitted by the power supply component 50 and supplies power to the radiating component 20. The inner shell 60 is a cylindrical structure made of plastic, and an accommodating space is formed inside the inner shell 60. The positioning structure is a protrusion on the inner wall of the inner shell 60. The positioning structure is connected to the first circuit board 10 and is used to fix the first circuit board 10 in a predetermined position inside the inner shell 60.

[0028] The battery assembly 91 is disposed within the inner shell 60, and the battery assembly 91 is a cylindrical lithium battery. A cushioning foam 90, made of annular non-conductive material, is disposed between the battery assembly 91 and the power supply assembly 50. The cushioning foam 90 is used to fix the battery assembly 91 and buffer the mechanical stress between the battery assembly 91 and the power supply assembly 50. The outer shell 70 is a cylindrical structure made of metal, enclosing the inner shell 60, forming a sealed internal space between the outer shell 70 and the inner shell 60.

[0029] The working principle of this embodiment is as follows: the power supply component 50 supplies power to the first circuit board 10, and the microstrip lines on the first circuit board 10 transmit electrical signals to the radiating component 20. The radiating component 20 forms an electrical connection through the connector 30, thereby constituting a complete radiating unit. The second circuit board 40 extends the ground plane of the first circuit board 10, and the resonant frequency of the radiating unit can be precisely controlled by adjusting the length of the second circuit board 40. This embodiment ensures the precise positioning of the first circuit board 10 within the inner shell 60 through the positioning structure, and protects the battery component 91 and avoids interference with the power supply component 50 through the buffer foam 90, thus realizing a compact and stable integrated antenna electronic cigarette 100.

[0030] Figure 4 The test results of the return loss of the radiating unit, consisting of the radiating component 20 and the connector 30 of the electronic cigarette, in the 2400-2500MHz frequency band are shown. The horizontal axis represents frequency (MHz), and the vertical axis represents return loss (dB). The test was conducted in a laboratory environment using a network analyzer.

[0031] from Figure 4 It can be seen that the return loss of the radiating element is less than -8.5dB throughout the entire 2.4GHz frequency band, indicating that the radiating element has good impedance matching characteristics and can effectively convert the fed electrical signal into electromagnetic wave radiation without generating excessive reflection loss.

[0032] Figure 5 The efficiency test results of the radiating element, consisting of the radiating component 20 and the connector 30 of the electronic cigarette, are shown in the 2400-2500MHz frequency band. The horizontal axis represents frequency (MHz), and the vertical axis represents efficiency (dB). The test was conducted in the SATIMO anechoic chamber, a professional antenna testing environment.

[0033] from Figure 5 As can be seen, the radiating element composed of the radiating component 20 and the connector 30 of the electronic cigarette has an efficiency greater than -9.5dB throughout the entire 2.4GHz frequency band. This indicates that the radiating element composed of the radiating component 20 and the connector 30 of the electronic cigarette can efficiently convert input power into radiated power with low loss. This efficiency level is quite excellent performance for a miniaturized integrated antenna.

[0034] These two test results verify the effectiveness of the hardware-integrated antenna combined with the FPC extended floor technology solution, proving that good antenna performance is achieved while maintaining a compact structure, meeting the technical requirements of Bluetooth and Wi-Fi communication.

[0035] Please continue reading. Figure 2 and combined Figure 3 The electronic cigarette 100 also includes a charging interface 80, which is a Type-C interface and is located at the end of the housing 70. The charging interface 80 has a first end and a second end, which are arranged along the length of the charging interface 80. The radiation assembly 20 includes a first radiating element 21 and a second radiating element 22, both of which are conductive screw structures. The first radiating element 21 is located at the first end of the charging interface 80, and the second radiating element 22 is located at the second end of the charging interface 80. The first radiating element 21 and the second radiating element 22 are spatially separated through the layout of the charging interface 80. A connector 30 is used to connect the first radiating element 21 and the second radiating element 22 respectively, and the connector 30 achieves electrical communication between the first radiating element 21 and the second radiating element 22 through its connection with the first radiating element 21 and the second radiating element 22.

[0036] Furthermore, the first circuit board 10 is also provided with a first threaded hole (not shown) and a second threaded hole (not shown). Both the first and second threaded holes are circular holes penetrating the thickness direction of the first circuit board 10, and the inner walls of both the first and second threaded holes are provided with threaded structures. The first end of the first radiating element 21 is screwed into the first threaded hole, and the first radiating element 21 forms a mechanical fixation and electrical connection with the first threaded hole through a threaded connection. The first end of the second radiating element 22 is screwed into the second threaded hole, and the second radiating element 22 forms a mechanical fixation and electrical connection with the second threaded hole through a threaded connection. The microstrip lines on the first circuit board 10 are respectively connected to the first threaded hole and the second threaded hole. The microstrip lines feed power to the first radiating element 21 through the first threaded hole, and feed power to the second radiating element 22 through the second threaded hole. The first radiating element 21 and the second radiating element 22 respectively receive electrical signals from the microstrip lines, and the first radiating element 21 and the second radiating element 22 form a complete radiation loop through the connector 30.

[0037] In this embodiment, a reliable connection between the first radiating element 21 and the second radiating element 22 and the first circuit board 10 is achieved by means of threaded connection. The spatial configuration of the first radiating element 21 and the second radiating element 22 is optimized by the layout of the charging interface 80, thereby realizing an integrated antenna electronic cigarette 100 with a stable structure and easy assembly.

[0038] Please continue reading. Figure 3 The connector 30 includes an annular portion 31, a first connecting portion 32, and a second connecting portion 33, and adopts a three-segment combined structure design. The annular portion 31 is a circular conductive structure, and its inner diameter matches the outer diameter of the radiating component 20. The first connecting portion 32 is a strip-shaped conductive structure, with its first end connected to the first side of the annular portion 31 and its second end extending to the connection position of the first radiating component 21. The second connecting portion 33 is also a strip-shaped conductive structure, with its first end connected to the second side of the annular portion 31 and its second end extending to the connection position of the second radiating component 22. The first connecting portion 32 is connected to the first radiating component 21, forming an electrical connection through welding. The second connecting portion 33 is connected to the second radiating component 22, forming an electrical connection through welding. The annular portion 31 connects the first connecting portion 32 and the second connecting portion 33 respectively. The annular portion 31 serves as an electrical bridge between the first connecting portion 32 and the second connecting portion 33, thereby realizing the electrical connection between the first radiating element 21 and the second radiating element 22.

[0039] Furthermore, the second circuit board 40 includes an adjustable section (not shown), which is an extension of the second circuit board 40. The length of the adjustable section can be adjusted as needed, and the length can be changed by folding, unfolding, or cutting. The adjustable section is connected to the floor end of the first circuit board 10, and the adjustable section forms an electrical connection with the floor end of the first circuit board 10 by soldering. The working principle of the adjustable section is as follows: when the floor length needs to be increased, the adjustable section unfolds more of its length; when the floor length needs to be decreased, the adjustable section folds or cuts off the excess length. By adjusting the effective length of the adjustable section, precise control of the electrical length of the entire floor system can be achieved, thereby adjusting the resonant frequency of the radiating unit.

[0040] In this embodiment, the design of the annular portion 31 increases the radiation area of ​​the connector 30. The combined structure of the annular portion 31, the first connecting portion 32, and the second connecting portion 33 ensures a stable electrical connection between the first radiating element 21 and the second radiating element 22, improving the radiation efficiency and directional uniformity of the radiating unit. This embodiment achieves a stable connection and frequency-adjustable integrated antenna electronic cigarette 100 through the three-section connector 30 structure of the annular portion 31, the first connecting portion 32, and the second connecting portion 33, and the design of the adjustable section of the second circuit board 40.

[0041] In this application, the connector 30 and the radiating component 20 are integrally molded structures, formed by integral casting or integral stamping to create a single continuous conductive structure. This integral molding structure eliminates contact resistance between the connector 30 and the radiating component 20, avoiding mechanical loosening issues caused by assembling multiple parts. Specifically, the two conductive parts of the radiating component 20 are physically and electrically connected via the conductive bridge portion of the connector 30. The two conductive parts of the radiating component 20 and the conductive bridge portion of the connector 30 are seamlessly connected as a single structure during manufacturing. The material of the integral molding structure is conductive metal, and the mold forming process ensures the accuracy and consistency of the dimensions of each part. The working principle of the integral molding structure is as follows: the power supply component 50 supplies power to the first circuit board 10, and the microstrip lines on the first circuit board 10 transmit electrical signals to the integral molding structure. The electrical signals flow unimpeded within the integral molding structure, and the overall conductivity of the integral molding structure ensures the efficient operation of the radiating unit. The manufacturing advantages of a unibody structure include: reduced number of parts, lower assembly complexity, and improved product reliability and consistency. The electrical advantages of a unibody structure include: elimination of contact resistance, reduced signal loss, and improved radiation efficiency.

[0042] In this embodiment, the adjustable section of the second circuit board 40 achieves length adjustment through a preset crease structure, and the effective electrical length of the adjustable section is controlled by the physical folding state. The positioning structure, through its mating connection with the edge of the first circuit board 10, achieves precise positioning and firm fixation of the first circuit board 10 within the inner shell 60. This embodiment, through the integrated molding structure design of the connector 30 and the radiating component 20, combined with the frequency adjustment function of the adjustable section and the installation positioning function of the positioning structure, realizes a simplified manufacturing and optimized performance integrated antenna electronic cigarette 100.

[0043] In this embodiment, the first radiating element 21 and the second radiating element 22 are threadedly connected to the first circuit board 10 through the first threaded hole and the second threaded hole. Simultaneously, the annular portion 31, the first connecting portion 32, and the second connecting portion 33 of the connecting element 30 are electrically connected to the first radiating element 21 and the second radiating element 22. The annular portion 31 is connected to the first radiating element 21 through the first connecting portion 32, and the annular portion 31 is connected to the second radiating element 22 through the second connecting portion 33, forming a complete electrical circuit. The first radiating element 21 and the second radiating element 22 achieve mechanical fixation and electrical connection with the first circuit board 10 through the threaded connection. The combined structure of the annular portion 31, the first connecting portion 32, and the second connecting portion 33 establishes a stable electrical bridge between the first radiating element 21 and the second radiating element 22. The combination of these two connection methods ensures the mechanical stability and electrical reliability of the radiating unit. The microstrip line transmits the electrical signals from the power supply component 50 to the first threaded hole and the second threaded hole, respectively. The electrical signals are then transmitted via threaded connections to the first radiator 21 and the second radiator 22. The first radiator 21 and the second radiator 22 are electrically connected through a connection network formed by the annular portion 31, the first connecting portion 32, and the second connecting portion 33. The battery component 91 provides power to the entire electronic cigarette 100. The cushioning foam 90 forms a buffer and insulation between the battery component 91 and the power supply component 50, preventing mechanical vibration of the battery component 91 from interfering with the power supply component 50, and simultaneously preventing the electromagnetic field of the power supply component 50 from adversely affecting the battery component 91. The positioning structure ensures the precise position of the first circuit board 10 within the inner shell 60, providing a stable reference position for the adjustment operation of the adjustable section. With the position of the first circuit board 10 fixed, the adjustable section controls the electrical characteristics of the entire floor system through length adjustment.

[0044] This application provides an electronic cigarette 100, including a first circuit board 10, a radiation component 20, a connector 30, a second circuit board 40, a power supply component 50, an inner shell 60, and an outer shell 70. The radiation component 20 is disposed on the first circuit board 10, and the connector 30 is disposed on the radiation component 20. The radiation component 20 and the connector 30 constitute a radiation unit. The second circuit board 40 is connected to the ground end of the first circuit board 10 and attached to the inner shell 60. The second circuit board 40 is used to extend the ground end of the first circuit board 10. The power supply component 50 is electrically connected to the first circuit board 10. The inner shell 60 is fixed to the first circuit board 10. The inner shell 60 is enclosed by the outer shell 70. By integrating the radiating component 20 and the connector 30 into a radiating unit, the structural components inside the electronic cigarette 100 are used as the radiating unit of the electronic cigarette 100. This eliminates the need for additional independent antenna elements, effectively freeing up the space originally occupied by independent antennas. This allows the electronic cigarette 100 to achieve high-performance wireless communication functions while maintaining a compact structure. Furthermore, by connecting the second circuit board 40 to the ground plane of the first circuit board 10 and extending the ground plane, the size of the ground plane can be precisely controlled, thereby effectively adjusting the resonant frequency of the integrated antenna, eliminating frequency offset problems, and ensuring the stable operation of the antenna in the target frequency band.
