Abstract

A personal computer suite (1) includes a computer (10), a monitor (20), a mouse (30), and a keyboard (40). The monitor, the keyboard and the mouse are electrically connected with the computer. The computer includes a plurality of manual switches (11) for respectively controlling a power source and various functions of the computer. The monitor has a display screen (21) for displaying images. The switches, the display screen, the mouse and the keyboard each include a photocatalyst layer portion at a surface thereof. The photocatalyst layer portion can react with water and oxygen molecules that are in contact with surfaces thereof to produce hydrogen ions, hydroxyl radicals and free oxygen radicals. Thus, sterilization of the personal computer suite is provided. In addition, the photocatalyst layer portions are super hydrophilic, which makes cleaning of the surfaces of the switches, the display screen, the mouse and the keyboard easy.

Claims

1. A personal computer aggregation comprising:

a computer having a plurality of switches provided thereon;

a display device;

an inputting device; and

a keyboard,

wherein the display device, the inputting device and the keyboard are each electrically connected with the computer, and each of the switches, the display device, the inputting device and the keyboard has a photocatalyst layer portion at a surface thereof.

2. The personal computer aggregation in accordance with claim 1, wherein the photocatalyst layer portions are formed on surfaces of the switches, the display device, the inputting device and the keyboard.

3. The personal computer aggregation in accordance with claim 1, wherein the photocatalyst layer portion comprises a photocatalyst material selected from the group consisting of titanium dioxide and zinc oxides.
