detailed description

Specific implementation mode one:

The present embodiment will be described below in conjunction with Figures 1, 2, and 3. The utility model relates to a dust-proof device, more specifically a dust-proof device for a computer host, including a top case 1, an outer case 2, an anti-slip strip 3, an inner case 4. The cooling hole 5, the power cord hole 6, the non-woven fabric 7 and the filter screen 8 can prevent dust from entering the main chassis without affecting the normal heat dissipation of the main chassis.

The top shell 1 is thermally sealed on the upper end of the outer shell 2 and the inner shell 4, the inner shell 4 is installed inside the outer shell 2, and there is a gap between the inner shell 4 and the outer shell 2, the anti-slip strip 3 is glued to the inner shell 4, and the power cord hole 6 They are respectively arranged on the outer shell 2 and the inner shell 4, and a communication pipe is provided between the power line hole 6 on the outer shell 2 and the inner shell 4, and the cooling holes 5 are respectively arranged on the outer shell 2 and the inner shell 4, and the holes on the outer shell 2 The central axis of the heat dissipation hole 5 is parallel to but not coincident with the central axis of the heat dissipation hole 5 on the inner shell 4, and the non-woven fabric 7 and the filter screen 8 are all bonded in the gap between the outer shell 2 and the inner shell 4, and the filter screen 8 is surrounded into a cylindrical shape to cooperate with the cooling holes 5 on the casing 2, and the non-woven fabric 7 is wrapped around the filter screen 8. During use, the top case 1 in the device is placed on the upper end of the main case, the inner case 4 is placed on the side end of the main case shell, and the anti-slip strip 3 prevents the device from falling off. During the normal use of the main case, because the non-woven fabric 7 has a good Air permeability, after the internal cooling fan of the main chassis rotates, the internal hot air passes through the heat dissipation holes 5 on the inner shell 4, the non-woven fabric 7 and the filter screen 8 in the gap between the inner shell 4 and the outer shell 2, and then passes through the vents on the outer shell 2 The cooling holes 5 are discharged, and the external dust enters the gap between the outer casing 2 and the inner casing 4 through the cooling holes 5 on the outer casing 2, and is blocked in the gap by the non-woven fabric 7 and the filter net 8 to prevent it from entering the main chassis , you only need to regularly clean up a small amount of dust accumulated in the device.
