Please refer to Figures 3 to 6. Figure 3 is an exploded schematic diagram of the cooling fan module and the air purification module of the host device of the first embodiment of the creation, and Figure 4 is the air purification of the first embodiment of the creation. A schematic diagram of the module's ultraviolet lamp emitting ultraviolet light toward the nano-level photocatalyst filter.

The computer host of e-sports level. Since the gaming-grade computer host has high requirements for heat dissipation, if the air volume provided by the cooling fan module 2 is less than 10 cubic feet per minute, the host device 100 may not be able to serve as the gaming-grade computer host. The heat dissipation fan module 2 may be fixed to the housing 1 by screws, and the heat dissipation fan module 2 may be a component (such as a motherboard) facing the host device 100 that easily generates heat. But this creation is not limited to this.

It should be noted that the fan blades of the existing cooling fan module may be coated with nano-grade titanium dioxide in order to provide an air purification effect. However, the nano-grade titanium dioxide coated on the fan blades will actually gradually peel off with the operation of the fan blades, so that the air purification effect provided by the nano-grade titanium dioxide coated on the fan blades is gradually reduced. In other words, it is difficult to compare the nano-grade titanium dioxide coated on the leaf with the nano-grade titanium dioxide in the nano-photocatalyst carrier 32 of this embodiment. In addition, in the nano-photocatalyst carrier 32 of this embodiment, since the nano-grade titanium dioxide is attached to the three-dimensional network structure 321, it is not only relatively difficult to peel off, but also provides a relatively high specific surface area.
