In view of this, an embodiment of the present invention provides a power socket device, the main purpose of which is to combine the functions of illumination and high temperature protection on the power socket device, thereby enabling the power socket device to function more widely and simultaneously Achieve the problem of effectively improving the safety of home protection.

Embodiments of the present invention provide a power socket device including a housing having a housing space, a power connector, a temperature sensing module, a transformer rectifier, a rechargeable battery, a lighting module, and a power-off switching module. The power connector is disposed in the housing for receiving external AC power; the power module is coupled to the power connector for providing AC power to at least one external electronic device; the temperature sensing module is coupled to the power connector and the power supply Between the modules, the temperature value of the power socket device is detected, and the temperature value is compared with the thermal threshold to control whether the link between the power connector and the power supply module is turned on or off; the transformer rectifier is coupled The power connector is configured to receive AC power and convert and rectify to generate DC power; the rechargeable battery is coupled to the transformer rectifier, and the transformer rectifier supplies DC power to the rechargeable battery to charge the rechargeable battery, and when the rechargeable battery is discharged The rechargeable battery is used for outputting battery power; the lighting module is disposed in the casing for projecting light to the outside of the casing; and the power-off switching module is coupled to the transformer rectifier, the rechargeable battery and the lighting module for detecting Whether the power connector receives AC power to control the link between the lighting module and the transformer rectifier and between the lighting module and the rechargeable battery Wherein one of the conductive link.

In summary, the temperature value of the power socket device is compared with a standard value of a superheat temperature by the built-in temperature sensing module, thereby controlling the power socket device to be powered off, so as to avoid continuous The high temperature causes the wire to escape, and the lighting module built in the power socket device can effectively improve the safety of home protection.
