Abstract
An exhaust fan for preventing air pollution includes a main body and at least one gas detection module. The main body is configured to form an airflow-guiding path and includes a gas guider and a filtration and purification component disposed in the airflow-guiding path. The gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source. The at least one gas detection module is disposed in the airflow-guiding path for detecting the air pollution source and transmitting gas detection data.
Claims16
An exhaust fan for preventing air pollution, comprising:
- a main body configured to form an airflow-guiding path and having a gas guider and a filtration and purification component disposed in the airflow-guiding path, wherein the gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source;
- at least one gas detection module disposed in the airflow-guiding path of the main body for detecting the air pollution source and transmitting gas detection data;
- and
- a microcontroller for receiving the gas detection data from the at least one gas detection module through a wireless communication transmission, and intelligently comparing the gas detection data under a surveillance status, so as to output a driving instruction to control an enablement of the gas guider and adjust a volume of guiding air-flow of the gas guider,
- wherein the air pollution source is continuously monitored in the surveillance status to ensure the gas detection data does not exceed a safety detection value.
