| 摘要 |
The present invention relates to an electrostatic air blower which is preferably intended for use in cleaning optofibers without risking the contamination of said fibers with, e.g., metal particles that may have been loosened from electrodes used in a cleaning process. The ends of optofibers can be cleaned simply and reliably prior to welding said ends together, with the aid of said electrostatic air blower. The electrostatic air blower includes two ceramic plasma caoons (11, 12) which face towards one another at a given distance apart. Each plasma cannon includes a ceramic tube which houses an electrode. Repeated discharges between the electrodes in the tubes causes pressure waves to be generated in the air present between the tube orifices. An optofiber (14) or the end of an optofiber placed in the proximity of the tube orifices close to the symmtry axis of said tube will be subjected to these pressure waves and any contaminants present, such an dust or dirt particles on the surface of the optofiber, will be blown away. |
