Document Type and Number:
WIPO Patent Application WO/2013/187271
Kind Code:

Abstract:
A piezoelectric blower (100) is provided with a housing (17), a top panel (37), a side panel (38), a diaphragm (39), a piezoelectric element (40), and a cap (42). The top panel (37), the side panel (38), and the diaphragm (39) constitute a blower chamber (36). A ventilation hole (45) is provided in the top panel (37). The diaphragm (39) and the piezoelectric element (40) constitute a piezoelectric actuator (41). Wall sections (43) and a disc-shaped suction port (53), which face the piezoelectric actuator (41), are formed in the cap (42). Herein, a central axis (X) of the suction port (53), which extends in the thickness direction of the wall section (43), and a central axis (Y) of the piezoelectric element (40), which extends in the thickness direction of the wall section (43), do not coincide. A ventilation path (31) is formed between the housing (17) and cap (42) and a junction for the top panel (37), the side panel (38) and the piezoelectric actuator (41).
