Title:
PIEZOELECTRIC BLOWER
Document Type and Number:
WIPO Patent Application WO/2014/148103
Kind Code:
A1
Abstract:
A piezoelectric blower (100) is provided with an outer casing (17) and a blower body (101). The outer casing (17) accommodates the blower body (101). The blower body (101) is provided with a top plate (80), a side plate (70), a first vibrating plate (60), a piezoelectric element (40), a middle plate (190), a second vibration plate (160), a side plate (170), and a bottom plate (180); and is constructed with these components layered in the stated order. The roof plate (80), the side plate (70), and the first vibrating plate (60) constitute a columnar first blower compartment (36), while the second vibrating plate (160), the side plate (170), and the bottom plate (180) constitute a columnar second blower compartment (136). The distance (K2) from a neutral plane (C) in the thickness direction of the piezoelectric element (40) to a surface (160A) of the second vibration plate (160) towards the piezoelectric element (40) is greater than the distance (K1) from the neutral plane (C) to a surface (60B) of the first vibration plate (60) towards the piezoelectric element (40).
