Covered with titanium dioxide layer, and installed bulbs in the front and rear screens; when the light is shining and rotating the blades, the suspended titanium particles in the air can be decomposed according to the excited titanium dioxide layer, and the air volume is distributed in the space to purify The effect of the air. However, in the first prior case, the sterilizing effect of the titanium dioxide photocatalyst is established on a vertical fan structure having a pedestal, which is bulky, inconvenient to carry, and cannot be installed in a confined space at random, for example, It is installed in an elevator (and the confined space such as the elevator is the fastest place for infectious bacteria), therefore, the place of the first predecessor is not widely applicable. Announcement No. 516610 (hereinafter referred to as the second pre-case) provides an "empty 1272951 sterilizing photocatalyst device" which is mainly installed on the air duct, air inlet or air outlet of an original air conditioning system. The above ultraviolet light-emitting diodes excite the titanium dioxide coated by the photocatalyst network to have a bactericidal action. However, the photocatalyst sterilization effect of the second predecessor is established in the structure of an air conditioning system, and the sterilization effect of the photocatalyst must be exerted by the activation of the air conditioning system. In a place where there is no air conditioning system, the sterilization cannot be performed and exerted. Photocatalyst sterilization effect, therefore, the second pre-existing case must consider whether there is an air-conditioning system when installing, the installation place is restricted, and the second pre-case is not portable, and cannot be moved and installed in any place. Therefore, the applicability of the second predecessor is not wide. SUMMARY OF THE INVENTION The present invention is designed to provide an innovative structure of a "titanium dioxide photocatalyst sterilization device" in view of the above-mentioned shortcomings of the conventional photocatalyst sterilization device, which can be carried at will, or can be randomly installed in any place.
