This creation is about an ozone generating device set in the air duct circulation, which is set in the air duct circulation of an air flow generating device, including: an air inlet； an ozone generating module； a fan module to generate ozone The ozone generated by the module is discharged out of the ozone generating device； an air outlet； and a controller that controls the ozone concentration of the ozone generated by the ozone generating module and the air volume of the air flow produced by the fan module, thereby enabling the discharge The ozone quickly spreads indoors, so it can effectively eliminate bacteria and viruses in the air, and purify the air to make the indoor air clean and fresh.本創作關於一種設於風道流通處之臭氧產生裝置，其係設於一風流產生裝置之風道流通處，包括有：一進風口；一臭氧產生模組；一風扇模組，將臭氧產生模組產生之臭氧排放出該臭氧產生裝置；一出風口；以及一控制器，控制該臭氧產生模組所產生臭氧之臭氧濃度及該風扇模組所製造之風流之風量，藉此能使排放之臭氧，快速散佈於室內，因此能高效能的消滅空氣中的細菌與病毒，淨化空氣使室內空氣乾淨清新。
