摘要：
The present invention provides a piezo pump, comprising: a body of which a solution supply unit is disposed at one side providing a space therein； a piezo element which is disposed in the body and has the length changed according to a signal applied from the outside； an operation load of which a rotary shaft is connected to an intermediate portion to be disposed on the inside of the body and which has an end portion reciprocating to correspond to a change in the length of the piezo element； a tappet which is disposed at one end of the operation load to open/close the solution supply unit according to an operation of the operation load； a displacement adjustment spring which is disposed at the other end of the operation load to apply elasticity to the operation load； an adjustment unit which is connected to an end portion of the displacement adjustment spring through one side of the body and adjusts a degree of compression of the displacement adjustment spring by a rotating operation； a display unit which displays a movement amount of the tappet to the outside； and a cooling unit which introduces air to the inside of the body to cool heat generated during an operation of the piezo element. According to the present invention, it is possible to change a displacement of a piezo by disposing a spring capable of adjusting elasticity at one side of the operation load disposed in the piezo pump, to replace a spring for changing a displacement of the operation load of the piezo pump, to measure a degree of an operation of the operation load of the piezo pump, and to inform a user of the measured degree in real-time.본 발명은, 내측으로 공간을 제공하는 일측으로는 용액 공급부가 배치되는 본체； 상기 본체의 내부에 배치되고 외부에서 인가되는 신호에 의해 길이가 변화되는 피에조 소자； 중간부에는 회전축이 연결되어 상기 본체 내측에 배치되고, 상기 피에조 소자의 길이 변화에 대응하여 단부가 왕복 동작하는 동작 로드； 상기 동작 로드의 일단에 배치되어 상기 동작 로드의 동작에 따라 상기 용액 공급부를 개폐하는 태핏； 상기 동작 로드의 타단으로 배치되어 상기 동작 로드에 탄성력을 인가하는 변위 조정 스프링； 상기 본체의 일측을 통해 상기 변위 조정 스프링의 단부에 연결되고 회전 조작에 의해 상기 변위 조정 스프링의 압축 정도를 조정하는 조정부； 상기 태핏의 이동량을 외
