It produces mechanical vibration, and the vibration is transmitted to the through-pipe 3 through the connecting body 4, the through-pipe 3 receives the vibration source, and through high-frequency vibration, the liquid transported to the through-pipe 3 by the infusion pump 1 via the infusion pipe 2 is atomized; The atomizing sheet 6 also generates a large amount of thermal energy while generating mechanical vibration. The shape memory alloy 5 that is close to the atomizing sheet 6 changes its shape due to the increase in ambient temperature and the heat energy generated by its own vibration.
