Title:
マイクロ気体輸送デバイス
Document Type and Number:
Japanese Patent JP7013271
Kind Code:
B2
Abstract:
A miniature gas transportation device (1) includes a gas outlet plate (11), a resonance plate (12), a piezoelectric actuator (13) and a covering member (16). The gas outlet plate (11) includes a gas outlet pipe (111), a gas outlet hole (112) and plural protrusion structures (113). The gas outlet pipe (111) is disposed on a first surface (11a) of the gas outlet plate (11). The gas outlet hole (112) is formed in the gas outlet pipe (111) and runs through the gas outlet plate (11) to output gas from the miniature gas transportation device (1). The plural protrusion structures (113) are disposed on a second surface (11b) of the gas outlet plate (11). A space between every two adjacent protrusion structures (113) of the plural protrusion structures (113) is defined as a vent portion (114). The piezoelectric actuator (13) includes a suspension plate (131), an outer frame (132), a bracket (134) and a piezoelectric element (133). The bracket (134) is arranged between the suspension plate (131) and the outer frame (132). The piezoelectric element (133) is attached on the suspension plate (131).
