Title:
STATIC-REMOVAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/085116
Kind Code:
A1
Abstract:
A static-removal apparatus, specially a static-removal apparatus with stable warning and illumining capacity, comprises a lower cover, an upper cover, a conductive front shroud, a conductive side cover and a circuit board. A switch transistor, a microprocessor, an indicating LED, an illumining LED, a switch, series of batteries and etc are deposited on the circuit board which is between the upper cover and the lower cover. A wire is provided at the front end of the circuit board for connecting the conductive front shroud, and a connecting plate is provided at the back end of the circuit board for conducting with the conductive side cover. Through above design, when a user contacts a matter carrying static charges with the conductive front shroud, the static charges are transmitted to the switch transistor of the circuit board through the wire and be ducted to ground via the connecting plate, the conductive side cover and the body of user. At the same time, the microprocessor obtains the signal from the switch transistor to activate the indicating LED at a constant voltage. Furthermore, the user can switch the illumining LED for lighting.
