Thermal coupling piezoelectric atomization structure, atomizer and using method of atomizer

The invention discloses a thermal-mechanical coupling piezoelectric atomization structure, an atomizer and a using method of the atomizer. The atomization structure comprises a shell, and an atomization unit, a heating unit and a control unit are sequentially arranged in the shell from top to bottom; the atomization unit comprises a heating cavity and an atomization cavity arranged in the heating cavity in a sleeved mode, a deformable spherical-crown-shaped thin plate is arranged at an opening of the atomization cavity, dense spraying holes with the wide upper portions and the narrow lower portions are formed in the central area of the spherical-crown-shaped thin plate, the spraying holes are closed when the spherical-crown-shaped thin plate protrudes upwards, and the spraying holes are expanded when the spherical-crown-shaped thin plate protrudes downwards. The edge of the spherical crown-shaped thin plate extends outwards to form an annular horizontal thin plate, and piezoelectric ceramics are adhered to th
