[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figs. 1 to 4This utility model provides a fire smoke detection early warning device based on the Internet of Things, including a power supply mechanism 1 and a smoke detector body 2. The power supply mechanism 1 includes a lithium battery 11, a microcontroller 14, a control switch 12 and a voltage sensor 15.

[0028] The main board of the smoke detector body 2 is equipped with a first power interface 13 and a second power interface 16.

[0029] The lithium battery 11 is connected in sequence to the control switch 12 and the first power interface 13 via wires;

[0031] The control switch 12 and the voltage sensor 15 are both electrically connected to the microcontroller 14;

[0032] In use, the mains power 17 provides power to the smoke detector body 2. When the external power is cut off, the voltage sensor 15 cannot detect the voltage in the second power interface. The voltage sensor 15 sends the power failure signal to the microcontroller 14. The microcontroller 14 turns on the control switch 12, and the battery supplies power to the first power interface 13, so that the smoke detector can resume working and ensure that the smoke detector can continue to work when the external power is cut off.

[0037] The working principle of this utility model is as follows:

[0038] The mains power 17 provides power to the smoke detector body 2. When the external power is cut off, the voltage sensor 15 cannot detect the voltage in the second power interface. The voltage sensor 15 sends the power failure signal to the microcontroller 14. The microcontroller 14 turns on the control switch 12, and the battery supplies power to the first power interface 13, so that the smoke detector can resume working. This ensures that the smoke detector can continue to work even when the external power is cut off. The camera body 3 can locate the specific fire location and fire situation through the camera while the smoke detector body 2 is detecting smoke, which facilitates rescue and firefighting work.
