DEVICE FOR GENERATING AIR SHELL

摘要

PROBLEM TO BE SOLVED: To provide a device for generating air shell, which can compress a gas existing inside an air sump part by vibrations and effectively discharge it to a place requiring a performance as the air shells and which is simple in configuration and small in size. SOLUTION: The device is provided with: a sealed case 1 forming an air accumulator; a vibration member 2 attached to an opening part for which at least one scheduled part of an air accumulator forming surface of the case 1 is opened; an air outlet 4 provided on the air accumulator forming surface of the case at a part different from the vibration member 2; and a rod 5 and a solenoid 6 provided inside the case 1 for pushing and pulling the vibration member 2 and vibrating the vibration member when a voltage is intermittently applied. The air inside the case 1 compressed by the vibration of the vibration member 2 is discharged from the air outlet 4 as the air shell in a fixed direction. COPYRIGHT: (C)2005,JPO&NCIPI
