Abstract: A cleaning brush for eliminating static electricity, including a conductive housing, wherein a containing slot is on a bottom surface of the conductive housing, and the conductive housing has two opposite end walls; and a conductive brush, which is embedded in the containing slot of the conductive housing, and is electrically connected to the conductive housing. Thus, the cleaning brush have both the functions for eliminating static electricity and removing dust.

Abstract: A dual-functional screen cleaner has a housing unit, a cleaning body, and a cleaning liquid container. The housing unit has a first housing and a second housing opposite the first housing. The first housing and the second housing have a first housing trough and a second housing trough respectively. The second housing trough has an upper housing trough and a lower housing trough opposite the upper housing trough. The cleaning body is removably accommodated in the lower housing trough. The cleaning liquid container is located in the upper housing trough.

Abstract: A cleaning disk for an optical pickup head of an optical disk drive has a disk body with a first surface and a second surface. The disk body uses at least one two-step hole portion to mount at least one brush bundle, wherein the two-step hole includes an embedded fine hole and an expansion hole. The brush bundle has a root portion and an end portion, wherein the root portion is fixed in the embedded fine hole, and the end portion protrudes towards the facing direction of the second surface through the expansion hole. When the brush bundle cleans the optical pickup head, the inner edge of the embedded fine hole on the first surface is used as a pivot point to bend the brush bundle into the expansion hole, thus reducing the resistance and wiping damage on the optical pickup head and the planar shifting of the cleaning disk.

Abstract: A two-in-one screen cleansing device includes a holding body having a first and a second section connected to each other back to back, and the first and the second section defining a first and a second chamber, respectively; a cleansing fluid dispenser removably held in the first chamber; and a cleansing unit removably held in the second chamber. The cleansing fluid dispenser and the cleansing unit are held together as an integral body by the holding body 1 to avoid the risk of getting separated from each other easily to cause inconvenience to a user. The user can use the cleansing fluid contained in the cleansing fluid dispenser without the need of removing the cleansing fluid dispenser from the holding body.

Abstract: An apparatus for cleaning head of pin-contact memory card slot mainly includes a base and a sheeted cleaning element. The base is provided at a front end surface with a recess, and the cleaning element is attached to the base so as to shield the front recess. When the base is plugged in a pin-contact memory card slot just like a memory card, contact pins provided in the head of the memory card slot pierce through the cleaning element attached to the front end of the base to locate in the front recess. The cleaning element is in contact with and thereby wipes clean outer surfaces of the contact pins when the latter pierce through the cleaning element.

Abstract: A device for destroying signals stored on compact disk includes a base, a punching pin, and a push lever. The base has a top stub for engaging with a central hole of a compact disk positioned on the base, a through hole corresponding to a Start Lead In (SLD) area on the compact disk, and an L-shaped arm portion holding a spring mechanism. The punching pin is vertically movably mounted in the spring mechanism and aligned with the SLD area, and the push lever is pivotally connected at an end to one side of the arm portion for pushing against an upper end of the punching pin. When the push lever is pivotally pushed downward, the punching pin is driven downward to punch a hole on the SLD area and ruin lead-in signals recorded thereon, preventing data stored on the compact disk from being read and disclosed.

Abstract: An integrated compact disc cleaning and labeling device mainly includes pivotally connected top and bottom covers, a turning plate rotatably fitted in the top cover, a CD cleaner rotatably mounted to one side of the turning plate, a sleeve barrel vertically slidably received in a barrel portion of the bottom cover, and a return spring mounted between the bottom cover and the sleeve barrel. The bottom cover includes an annular seat surrounding the barrel portion for supporting a label thereon. When a compact disc is removably supported on a flat top of the sleeve barrel with a print side facing downward and the top cover is closed onto the bottom cover, the label is attached to the print side of the compact disc. Meanwhile, the CD cleaner could be rotated to effectively clean a signal side of the compact disc and ensure a firm attachment of the label to the compact disc.

Abstract: The present invention relates to a compact disc cleaner which includes a box base having a cover and a seat, a turntable that is rotated on the cover, a cleaning device moveably attached at the near end of the turntable that includes a knob and a wheel body on the exterior and interior of the turntable, a cleaning element attached underneath the wheel body and gear teeth on the external wall of the wheel body that engage with the gear teeth on the internal wall of the box base. The cover is pivoted, at one end, with the seat in which the compact disc is held. When the user rotates the knob of the cleaning device, the turntable will revolve as the same time and the internal gear of the box base will bring the wheel body on the cleaning device to rotate within the radius of the compact disc so to effectively clean the compact disc with the cleaning element underneath the wheel body.
