Working principle of the present invention:
When bionic piezoelectric pump work of the present invention, a circulation can be divided into two processes.Two flexible piezoelectrics drive
The alternating current voltage phase difference that the work of movable plate uses differs 180 degree, i.e., the same time is made of two flexible piezoelectric driving pieces
Two oscillators direction of vibration conversely, because two oscillators in this configuration, i.e. flexible piezoelectric driving piece B6 and flexible piezoelectric
It is symmetrically placed for driving piece A17, so two oscillator vibration directions show as vibrating to same direction.In process one, flexibility pressure
When electric drive piece A17 vibrates upwards, the volume of upper chamber A increases, and pressure reduces, while flexible piezoelectric driving piece B6 shakes upwards
Dynamic, the volume of chamber B reduces, and pressure increases.In the process, the pressure of chamber B is consistently greater than the pressure of chamber A, so valve
Film valve B9 is in close state always.Chamber A pressure is less than external pressure, and under the action of external pressure, valvular valve A14 is beaten
It opens, medium is inhaled into chamber A.Meanwhile the pressure of chamber B is greater than external pressure, valvular valve B9 is opened, and medium flows out chamber B.
In process two, oscillator flexible piezoelectric driving piece A17 vibrates downwards, and the volume of chamber A reduces, and pressure increases；Oscillator flexibility pressure
Electric drive piece B6 vibrates downwards, and chamber B volume increases, and pressure reduces.In the process, the pressure of chamber A is greater than external pressure,
The simultaneously greater than pressure of chamber B, chamber B pressure are less than external pressure, under the action of pressure difference, valvular valve A14 and valvular valve
C1 is closed, and valvular valve B9 is opened, and medium flows into chamber B by chamber A.As soon as complete process and process two, chamber A and chamber B are complete
At primary sucking and discharge process.
In this cyclic process, some the lesser occasion of pressure fluctuation is required due to being not suitable with there are pressure fluctuation.Institute
With the preferred flexible material of material of the invention.Overall structure uses flexible material, can effectively absorb part pulsation, be implanted into simultaneously
