Piezoelectric micro-jet device and seedling culture device adopting same

The invention belongs to the field of micro-jet, and particularly relates to a piezoelectric micro-jet device and a seedling culture device adopting the same. The whole piezoelectric micro-jet device is composed of a joint, an upper cover, a lower cover, a piezoelectric vibrator, a sealing ring, a one-way valve and a nozzle, a long and thin pipeline and an energy storage cavity are arranged at the nozzle, during spraying, entered bubbles supply a buffered zone, the phenomenon that bubbles directly enter a pump cavity is avoided by means of the long and thin pipeline, and then, the piezoelectric micro-jet device can reliably work for a long time. The seedling culture device comprises a water tank, a water tank supporting frame, a connecting pipe, a box cover, a culture box, the piezoelectric micro-jet device, seedlings and a culture medium. By combining multiple piezoelectric micro-jet devices, seedlings can be evenly and comprehensively sprayed. 本发明属于微型喷洒领域，具体涉及一种压电微喷装置及使用该装置的幼苗培养设备。该压电微喷装置整体由接头、上盖、下盖、压电振子、密封
