Intelligent networked exhaust fan

An intelligent networked exhaust fan, comprising:

• a main body comprising an air suction port and an air exhaust duct, wherein an air guiding path is disposed between the air suction port and the air exhaust duct;
• at least one air guiding fan disposed in the air guiding path of the main body for guiding air to exhaust;
• a host driving controller controlling activation operation of the at least one air guiding fan, and dynamically adjusting an operating frequency and an output air volume of the at least one air guiding fan;
• and
• at least one gas detection module electrically connected to the host driving controller, wherein the at least one gas detection module detects air pollution to generate a detection data, the detection data is transmitted to a networked cloud computing service device through IoT communication, and the networked cloud computing service device collects and analyzes the detection data in real time, intelligently selects and generates a control command according to the detection data, and transmits the control command to the at least one gas detection module for receiving, so that the host driving controller regulates the activation operation of the at least one air guiding fan, and dynamically adjusts the operating frequency and the output air volume of the at least one air guiding fan, to achieve real-time monitoring.
