Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically to a socket with a replaceable communication system. Background Technology

[0002] With the rapid development of IoT technology, smart sockets, as core control nodes for home devices, are gradually becoming an indispensable component of smart home scenarios. Traditional sockets have limited functionality, providing only basic power access and failing to meet modern users' needs for intelligent control, multi-protocol compatibility, device status monitoring, and data transmission. Furthermore, existing smart sockets mostly use fixed communication modules (such as Wi-Fi, Bluetooth, or ZigBee), leading to difficulties in device upgrades, poor compatibility, and the need for external adapters to switch between different communication protocols, increasing system complexity and cost.

[0003] Existing power management solutions generally suffer from low efficiency and high heat generation. Especially when multiple modules work together, insufficient voltage stability can easily lead to performance fluctuations in critical components such as RF circuits and sensors. Meanwhile, traditional sockets lack real-time monitoring capabilities for the physical state of devices (such as insertion / removal actions and accidental displacement), resulting in weak safety protection. Furthermore, existing USB interface circuits typically lack integrated multi-layer protection mechanisms, making them susceptible to damage to internal components under abnormal operating conditions such as overvoltage and surges, thus affecting device reliability.

[0004] To address the aforementioned issues, there is an urgent need for a smart socket solution that features a replaceable communication system, efficient power management, multi-state monitoring, and high compatibility, in order to improve user experience, extend device lifespan, and reduce maintenance costs.
