A medicine accommodating structure includes a medicine accommodating unit and a movable unit. The medicine accommodating unit is disposed in a receiving space, and the medicine accommodating unit includes a medicine accommodating space and a first opening communicated between the receiving space and the medicine accommodating space. The movable unit is movably disposed between the receiving space and the medicine accommodating space through the first opening. At least one pharmaceutical capsule having a medicinal liquid received therein is placed inside the medicine accommodating space. Whereby, when the movable unit is moved from the receiving space into the medicine accommodating space, the movable unit can pierce into the at least one pharmaceutical capsule, such that the medicinal liquid can flow from the at least one pharmaceutical capsule into the receiving space.
