The invention provides a piezoelectric type atomization device which comprises a needle tube, a middle connecting piece and a piezoelectric transducer, the needle tube is arranged above the piezoelectric transducer, the needle tube and the piezoelectric transducer are fixedly connected through the middle connecting piece, a plurality of first grooves are formed in the side wall of the needle tube, and the first grooves are communicated with the middle connecting piece. Second grooves are formed in the middle positions of the two sides of the middle connecting piece. According to the invention, the needle tube and the piezoelectric transducer are fixed by adopting the middle connecting piece, so that the piezoelectric transducer can be prevented from generating energy loss such as torsion during high-frequency vibration; grooves are formed in the middle positions of the two sides of the middle connecting piece and the needle tube, a flexible hinge is formed, the rigidity of the middle connecting piece and the
