Document Type and Number:
Japanese Patent JP5692468
Kind Code:
B2
Abstract:
Provided is a blower configured so that a reduction in the discharge flow rate and a reduction in the discharge pressure are minimized, rendering the blower less likely to stop operating due to foreign matter than conventional products. A piezoelectric blower (100) is provided with an outer housing (17), a top plate (37), a side plate (38), a vibration plate (39), a piezoelectric element (40), and a cap (42). The top plate (37), the side plate (38), and the vibration plate (39) constitute a blower chamber (36). A first opening (45) is provided in the top plate (37). A second opening (34) for connecting the inside and outside of the blower chamber (36) is provided in a region of the vibration plate (39), the region facing the first opening (45). When an AC drive voltage is applied to the piezoelectric element (40), the vibration plate (39) flexes and vibrates, and the top plate (37) also flexes and vibrates as the vibration plate (39) flexes and vibrates. Consequently, the volume of the blower chamber (36) periodically changes as shown in Fig. (4)(A) and (B).
