[0023] 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.
[0024] Please see Figure 1 The electronic cigarette 100 includes a substrate 10, a circuit board (not shown), an antenna unit 30, a charging interface 40, an isolator 50, and a connecting line 60. The antenna unit 30 is disposed on the substrate 10 and includes a radiating portion (not shown), a feeding portion (not shown), and a ground portion (not shown). The charging interface 40 is disposed on the antenna unit 30 and includes a positive terminal (not shown) and a negative terminal (not shown). The positive terminal of the charging interface 40 is electrically connected to the feeding portion of the antenna unit 30, and the negative terminal of the charging interface 40 is electrically connected to the ground portion of the antenna unit 30.
[0025] In this embodiment, the substrate 10 is made of FR4 material, which has good mechanical strength and electrical properties, providing a stable mounting base for the antenna element 30. The antenna element 30 is made of double-sided copper-clad FPC (flexible printed circuit), and the antenna pattern is printed on the substrate 10 through a printing process.
[0026] In this embodiment, the charging interface 40 is disposed on the antenna element 30 and mounted using surface mount technology (SMT). The charging interface 40 includes a positive terminal and a negative terminal, wherein the positive terminal is electrically connected to the feed section of the antenna element 30, and the negative terminal is electrically connected to the ground section of the antenna element 30. Through the above arrangement, the antenna's feed path also serves as the charging path, achieving structural simplification and space saving.
[0027] In this embodiment, one end of the connecting line 60 is connected to the antenna unit 30, and the other end is connected to the circuit board. The connecting line 60 adopts a coaxial cable structure, ensuring the stability and reliability of signal transmission. Through this connection method, the charging interface 40 is connected to the circuit board via the connecting line 60 to realize the charging function, and the antenna unit 30 is connected to the circuit board via the connecting line 60 to realize the wireless communication function.
[0028] An isolator 50 is disposed between the antenna element 30 and the charging interface 40 to reduce the impact of the charging interface 40 on the radiation performance of the antenna element 30. One end of the connecting line 60 is connected to the antenna element 30, and the other end is connected to the circuit board. With this structural design, the charging interface 40 achieves the charging function by connecting to the circuit board through the connecting line 60, and the antenna element 30 achieves the wireless communication function by connecting to the circuit board through the connecting line 60.
[0029] The circuit board is built into the main body of the electronic cigarette 100 and is responsible for signal processing and power management. The circuit board is equipped with a Bluetooth communication module for processing wireless communication signals; it also has a power management circuit for controlling the charging process and power distribution.
[0030] In this embodiment, the isolator 50 is made of non-metallic materials such as EVA foam. The main function of the isolator 50 is to reduce the impact of the charging interface 40 on the radiation performance of the antenna element 30, and to ensure the antenna's radiation pattern characteristics and radiation efficiency.
[0031] Antenna element 30 adopts a monopole antenna structure, with the length of its radiating section being one-quarter of the wavelength of the operating frequency. The operating frequency band is 2400-2500MHz, meeting the requirements of the Bluetooth communication standard. This design ensures that the antenna achieves sufficient radiation efficiency within a limited space.
[0032] Please see Figure 2To enhance the overall structural strength of the electronic cigarette 100, this embodiment also includes a reinforcing plate 80, which is disposed below the substrate 10 and fixedly connected to the substrate 10. The reinforcing plate 80 is made of FR4 material with a thickness of approximately 1.0 mm, effectively improving the product's bending resistance and impact resistance. In some embodiments, the reinforcing plate 80 and the substrate 10 are connected by a snap-fit or adhesive method to ensure a firm and reliable connection. This structural design enhances the product's durability.
[0033] In this embodiment, when the electronic cigarette 100 is working, the internal battery powers the Bluetooth communication module via the circuit board. The high-frequency signal generated by the Bluetooth communication module is transmitted to the antenna unit 30 via the connecting line 60, and then radiated outward by the antenna unit 30 to achieve wireless communication with external devices (such as smartphones). When the battery is low and needs charging, an external power source is connected via the charging interface 40, and electrical energy is transmitted to the circuit board via the connecting line 60, which then controls the charging of the battery. The entire charging process is monitored by the charging management circuit on the circuit board to ensure safe and reliable charging. Through the above design, this embodiment integrates the charging interface 40 and the antenna unit 30, solving the space limitation problem in the miniaturization design of the electronic cigarette 100, while ensuring good antenna performance and meeting the requirements of Bluetooth communication.
[0034] Please refer to further information. Figure 2 The electronic cigarette 100 is provided with a dedicated groove 70, the shape and size of which match the spacer 50 for accommodating and fixing the spacer 50.
[0035] The isolator 50 includes an isolating body and a fixing protrusion (not shown). In this embodiment, the isolating body is flat and disposed between the upper surface of the antenna unit 30 and the lower surface of the charging interface 40. The thickness of the isolating body needs to ensure that the charging interface 40 and the antenna unit 30 maintain a sufficient distance to reduce electromagnetic interference, without excessively increasing the overall thickness of the device.
[0036] The fixing protrusions are provided on the lower surface of the isolation body and are evenly distributed along the edge of the isolation body. The fixing protrusions cooperate with the grooves 70 on the body of the electronic cigarette 100. When the isolation component 50 is installed, the fixing protrusions are embedded in the grooves 70 to achieve self-locking and ensure that the isolation component 50 can be firmly fixed in the predetermined position.
[0037] In this embodiment, a specific shaped concave-convex structure is designed in the isolation body area below the charging interface 40. These structures can effectively adjust the electromagnetic field distribution, further reducing the impact of the charging interface 40 on the antenna element 30. Furthermore, the outer contour of the isolator 50 maintains a certain distance from the radiating portion of the antenna element 30, avoiding adverse effects on the antenna's radiation characteristics. Simultaneously, the thickness of the isolator 50 in the area near the charging interface 40 is slightly greater than in other areas, creating a gradient change. This design further optimizes the electromagnetic field distribution.
[0038] In this embodiment, when installing the isolator 50, the fixing protrusion of the isolator 50 is first aligned with the groove 70 on the main body of the electronic cigarette 100, and then appropriate pressure is applied to make the fixing protrusion fully embedded in the groove 70. During the installation process, a dedicated positioning fixture is used to ensure that there is no relative displacement between the isolator 50 and the antenna unit 30, thus ensuring installation accuracy. After installation, a stable gap is formed between the isolator 50 and the antenna unit 30, and the charging interface 40 is installed above the isolator 50, forming a tightly integrated whole structure. This assembly method not only improves the reliability of the product but also simplifies the manufacturing process and improves production efficiency.
[0039] Please combine Figure 3 and Figure 4 Through experimental testing, the antenna element 30, using the isolator 50 design described in this embodiment, achieves an excellent return loss of less than -6.4dB and an antenna efficiency better than -8.7dB, fully meeting the technical requirements of Bluetooth communication. Compared with traditional designs, the isolator 50 design in this embodiment improves antenna efficiency by approximately 15% and increases communication distance by approximately 20%, significantly improving the wireless communication performance of the electronic cigarette 100 and enhancing the user experience.
[0040] In this embodiment, the connecting line 60 includes two functional areas: a signal transmission section and a power transmission section. The signal transmission section consists of a thin-diameter wire and is connected to the feed section of the antenna unit 30, responsible for transmitting the high-frequency signals required for Bluetooth communication. The power transmission section consists of a thicker-diameter wire and is connected to the positive terminal of the charging interface 40, responsible for power transmission and supporting the charging function. Furthermore, the connecting line 60 adopts a coaxial structure design, with the center conductor used for signal transmission and the outer conductor used for power transmission and shielding. This structure effectively isolates signal transmission and power transmission, reduces mutual interference, and improves the quality of signal transmission and the efficiency of power transmission.
[0041] Please refer to further information. Figure 2In this embodiment, the electronic cigarette 100 also includes a battery component 90, which is electrically connected to the charging interface 40 via a circuit board. The battery component 90 uses a high-energy-density lithium-ion battery with a capacity typically between 200mAh and 500mAh, sufficient for extended use of the electronic cigarette 100. The battery component 90 is connected to the circuit board via a dedicated battery connector, ensuring the reliability and stability of the electrical connection. A power management chip on the circuit board monitors the charging and discharging state of the battery component 90, implementing safety functions such as overcharge protection, over-discharge protection, and overcurrent protection to ensure user safety.
[0042] In this embodiment, when an external power source charges the electronic cigarette 100 through the charging interface 40, electrical energy is first transmitted to the circuit board via the power transmission section of the connecting cable 60, and then the circuit board controls the charging of the battery assembly 90. During the charging process, the circuit board monitors the charging current and battery voltage in real time to ensure safe and reliable charging. When the electronic cigarette 100 engages in Bluetooth communication, the battery assembly 90 supplies power to the circuit board, and the Bluetooth communication module on the circuit board generates a high-frequency signal, which is transmitted to the antenna unit 30 via the signal transmission section of the connecting cable 60 to achieve wireless communication. The materials and structure of the connecting cable 60 have been optimized. The signal transmission section uses a material with good high-frequency transmission characteristics to reduce transmission loss; the power transmission section uses a low-resistance material to reduce energy loss and improve charging efficiency.
[0043] In this embodiment, the substrate 10 is further provided with a tuning structure (not shown) for adjusting the resonant frequency of the antenna element 30. The tuning structure is located in the feed section of the antenna element 30, and the tuning includes multiple fine-tuning capacitor regions and inductor regions. The fine-tuning capacitor regions and inductor regions are finely tuned by laser cutting or mechanical cutting to change the electrical characteristics of the antenna and achieve precise adjustment of the resonant frequency.
[0044] When a user holds the e-cigarette 100, the dielectric constant and conductivity of the human body affect the resonant frequency of the antenna; similarly, frequency shifts will occur when the e-cigarette 100 is placed on a metal surface or when there are metal objects nearby. The tuning structure can compensate for these conditions, ensuring that the antenna maintains good performance in various usage environments.
[0045] The tuning process typically takes place after product assembly. Technicians use a network analyzer to measure the antenna's return loss curve and fine-tune the tuning structure based on the measurement results until the antenna's resonant frequency accurately falls in the center of the Bluetooth band and the return loss meets design standards.
[0046] Please see Figure 3 and Figure 4The performance of antenna element 30 was verified using a professional antenna testing system. The antenna pattern was tested in a GTS1800 anechoic chamber, and the antenna return loss was tested using a network analyzer. The test results show that the antenna design of this embodiment achieves excellent performance indicators, with a return loss of less than -6.4 dB and an antenna efficiency better than -8.7 dB.
[0047] Based on the test results, the antenna design parameters were further optimized. By fine-tuning the geometry and size of the antenna radiator 31, the antenna's bandwidth characteristics were optimized, ensuring stable performance across the entire Bluetooth frequency band. Simultaneously, improvements to the antenna feed point design enhanced impedance matching, reduced signal reflection, and improved energy transfer efficiency.
[0048] This application provides an electronic cigarette 100, including a substrate 10, a circuit board, an antenna unit 30, a charging interface 40, an isolator 50, and a connecting line 60. The antenna unit 30 is disposed on the substrate 10 and includes a radiating part 31, a feeding part, and a grounding part. The charging interface 40 is disposed on the antenna unit 30 and includes a positive terminal and a negative terminal. The positive terminal of the charging interface 40 is electrically connected to the feeding part of the antenna unit, and the negative terminal of the charging interface 40 is electrically connected to the grounding part of the antenna unit. The isolator 50 is disposed between the antenna unit 30 and the charging interface 40. One end of the connecting line 60 is connected to the antenna unit, and the other end of the connecting line 60 is used to connect to the circuit board. The charging interface 40 achieves its charging function by connecting to the circuit board through the connecting line 60. The antenna unit 30 is connected to the circuit board via the connecting line 60 to achieve wireless communication. By integrating the charging interface 40 with the antenna unit 30, the charging and wireless communication functions are integrated, effectively solving the space limitation problem in the miniaturized design of the electronic cigarette 100 and improving space utilization. An isolator 50 is placed between the antenna unit 30 and the charging interface 40 to reduce the interference of the charging interface 40 on the antenna performance, ensuring that the antenna radiation efficiency is maintained at a good level and guaranteeing the quality of wireless communication. By sharing an electrical connection path between the charging interface 40 and the antenna unit 30, the circuit design is simplified, the assembly complexity is reduced, and the material usage and production costs are reduced.
