るピエゾポンプ。 A pump chamber is formed by sealing and fixing the periphery of a diaphragm to which a piezoelectric ceramic plate is attached, which alternately expands and contracts when an alternating current voltage is applied, to the rim of a hole formed in the pump body with a gasket.
A portion of the diaphragm fixed to the pump body in a piezo pump configured to alternately increase and decrease the volume of the pump chamber by vibration of the diaphragm so that fluid sucked in from the suction port is discharged from the discharge port. and a portion to which the piezoelectric ceramic plate is attached, a portion that is easy to bend is formed between the piezoelectric pump and the portion to which the piezoelectric ceramic plate is attached.
