This creation provides an air sterilization device, especially an air sterilization device that is hung in the trough of a light steel frame or fixed in elevators, stairs, passages, and room ceilings for indoor use. The characteristics of the air sterilization device of this creation are used The exhaust fan draws indoor air into the box. The ultraviolet light source installed in the box is used to kill and eliminate bacteria and viruses in the air with the ultraviolet light source. When the ultraviolet light source is activated, the air will It produces a pungent ozone smell. In this creation, the ultraviolet light emitter of the device is covered with a photocatalyst to dissolve the smell. The device as a whole allows the room to effectively maintain fresh air circulation.本創作提供一種空氣滅菌裝置，尤指供室內使用吊掛於輕鋼架之格槽內或固定於電梯、樓梯、通道及房間天花板等處的空氣滅菌裝置，本創作空氣滅菌裝置之特徵係利用抽風扇將室內空氣抽入箱內，該藉由箱內設置之紫外線光源，並將帶有細菌及病毒之空氣利用該紫外線光源進行將其殺死並消滅，因啟動紫外線光源時，空氣中會產生刺鼻臭氧味，本創作係於裝置之紫外線發光器上套設有光觸媒來化解此臭味，其裝置整體上使得室內有效保有新鮮空氣流通。
