ポンプ。 A pump section that sucks in and discharges liquid in a fixed direction using a reciprocating piston is provided below the liquid surface, and a piezoelectric vibrator supported in a cantilevered manner is provided above the liquid surface.
In a piezoelectric pump configured to transmit the motion of a vibrating end of the piezoelectric vibrator to the piston by a joint member provided through the liquid surface, the piezoelectric pump has a through hole provided at a rear part of the piston at right angles to its axis; A cross-sectional shape is formed such that the inner diameter in the direction perpendicular to the axis is larger than the inner diameter in the axial direction, and the tip of the joint member made of a rigid rod is inserted into the through hole. A piezoelectric pump characterized by being inserted through it.
