Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to an electronic cigarette. Background Technology

[0002] E-cigarettes are electronic products that mimic traditional cigarettes. They work by heating and atomizing a nicotine-containing liquid to produce inhalable vapor, thus simulating the smoking experience. E-cigarettes were initially designed to provide smokers with a safer alternative to traditional cigarettes, while also helping those trying to quit reduce their nicotine dependence. As an alternative to traditional cigarettes, e-cigarettes offer certain health advantages and convenience, but they also face health risks and regulatory challenges. With technological advancements and improved policies, the e-cigarette industry is expected to develop in a safer, healthier, and more sustainable direction in the future.

[0003] Some e-cigarettes have built-in antennas to transmit signals to mobile phones, allowing users to monitor the duration of use and the liquid level in real time via their phones. However, existing e-cigarette products generally use metal casings to improve their appearance. Metal materials significantly impact the antenna's radiation performance, resulting in lower radiation efficiency. Furthermore, the compact internal space of e-cigarettes leaves little room for the antenna, further affecting its performance. Utility Model Content

The main control board is electrically connected to both the PCBA board 4 and the battery 3. The plastic cover 2 has a window for exposing the charging interface 5. The plastic cover 2 is located at... An LDS antenna 6 is provided on the end face away from the battery 3. The LDS antenna 6 is used to realize Bluetooth function, that is, the LDS antenna 6 is a Bluetooth antenna. The LDS antenna 6 is electrically connected to the PCBA board 4 through a conductive probe 7. The PCBA board 4 is also provided with a spring contact 8. The inner wall of the outer shell 1 is provided with an LDS grounding wire 9 that abuts against the spring contact 8 and conducts through it. The spring contact 8 is made of a metal conductive material, such as copper. The spring contact 8 and the charging interface 5 are surface mounted on the PCBA board 4 through SMT process.
