A press-type medical aerosol generating device includes a medicament storage container (100), a nebulizer (200) provided in the medicament storage container (100) and a pressing mechanism (300). The pressing mechanism (300) includes a base (310) and a pressing element (320). The base (310) has a gas conduit (311) inserted into the nebulizer (200) and a pressure relief hole (312) communicating with the gas conduit (311). The pressing element (320) includes an operating arm (321), a valve (322) and an elastic arm (323) abutting the medicament storage container (100). When the operating arm (321) is turned to rotate, the valve (322) closes the pressure relief hole (312), so that the nebulizer (200) aerosolizes the medicament. When the operating arm (321) is released, the elastic arm (323) causes the valve (322) to open the pressure relief hole (312), so that the compressed gas can be exhausted to the outside to thereby stop the aerosolizing of the medicament.
