Abstract: A photocatalytic electric fan comprises a main body having a receiving tank therein. A motor is fixed in the receiving tank. A rotation shaft of the motor is connected with a fan blade. A lamp-fixing element is joined at an opening of the main body near the fan blade. A photocatalytic lamp is positioned on the lamp-fixing element. At least a photocatalytic lamp tube is disposed on the lamp. Each photocatalytic lamp tube is connected to an electric connection seat, a stabilizer, a starter, a switch, and a power source. A face net is joined at the other opening of the main body. The face net is rotatable. The photocatalytic lamp tube is a UV lamp tube with a glass-fiber-cloth sleeved outside. The glass-fiber-cloth has a photocatalytic coating formed of titanium dioxide.

Abstract: An advertising and display lamp box with optical catalyst waste gas treatment, including a lamp box main unit, an imaging panel, a waste gas treatment ultraviolet (UV) lamp and a compulsory convection device. On the lamp box main unit are air inlets and air outlets. A panel made of transparent or see-through plastic or glass material is installed at the front of the lamp box, presenting transparent or see-through advertising pictures or media materials that need backlight display. The waste gas treatment UV lamp is installed inside the lamp box main unit. . The compulsory convection device is installed on the lamp box main unit, for drawing outside air through the air inlets into the lamp box main unit. Air flows through the waste gas treatment UV lamp out of the air outlets.
