| 摘要 |
The invention concerns a cleaning device for casing components of electronic devices such as laptop computers, keyboards, monitors and such which are susceptible to dust. The device has a cuboidal block (10) made of a flexible material which on its underside, which is the surface of the block intended to contact the surface being cleaned, has a large number of incisions (14) which run crossways and form flexible fins (16) which can be deflected outward toward both sides. When the device is in use the fins spread and create slits (22) to collect dust. The incisions preferentially stretch over two thirds of the height of the block and run virtually parallel to its sides, so that the fins have a rectangular cross-section. The block is preferentially made of a soft foam.
