摘要： A suction head (10) for an extraction cleaner (132) including a base (12) forming a suction chamber (16) and a suction outlet (26) in fluid communication with the suction chamber (16); and a piezoelectric element (14) coupled to the base (12), the piezoelectric element (14) comprising a first surface (40) open to the suction chamber (16), a second surface (42) facing an external environment (34) away from the suction chamber (16), a thickness (44) between the first surface (40) and the second surface (42), and a through-via (46) through the thickness (44) open at both the first surface (40) and the second surface (42). An extraction cleaner (132) including the suction head (10).
