Description

Technical Field

[0001] This utility model relates to a charger, specifically to a charging device with waterproof function. Background Technology

[0002] With the development of the 3C (Computer, Communication, and Consumer) industry, more and more consumers are using mobile devices as auxiliary tools in their lives. For example, common mobile devices include tablets, mobile phones, and smartphones. These mobile devices are small and portable, and their use has become an indispensable part of most people's lives.

[0003] With the booming development of various types of software applications, including social media, the internet, and video games, people's dependence on various electronic products has become increasingly deep. As the time spent using electronic devices increases, the problem of insufficient power is more likely to occur. Furthermore, as these electronic devices become increasingly thinner and lighter, the power that the internal batteries can store is becoming more limited. Therefore, the use of external power supply devices such as power banks is becoming more and more widespread.

[0004] In existing technologies, due to portability requirements, it is necessary to minimize the size of the battery while ensuring sufficient power supply and long battery life. Consequently, the battery chargers used with it also follow the same trend.

[0005] To indicate the status of the charging device (power bank), an indicator light is provided. This light guide uses a light-guiding element to direct light from an internal light-emitting element to the outside of the casing. Users can then observe the indicator light to determine the charging device's operating status and take appropriate action in case of a malfunction. However, existing electronic devices have gaps between the light guide element and the casing, necessitating waterproofing measures to prevent malfunctions caused by moisture. Previous technologies primarily used potting compound for waterproofing the light guide pillar of charging devices, lacking waterproofing design for moving parts (such as buttons).

[0006] In view of this, it is necessary to propose a novel waterproof mechanism for light guide pillars and button modules to address the shortcomings of existing technologies. Utility Model Content
