An atomisation device, comprising: an atomisation apparatus (100), a control apparatus, a hood apparatus, an air suction apparatus, a filter apparatus, and a bracket. The atomisation apparatus is provided with a liquid storage area (110), an output area (120), an atomisation area (130) and an inhalation area (140). The control apparatus is connected to every output part, which are used for outputting, under the control of the control apparatus, a predetermined amount of medicinal liquid from a liquid storage part to the atomisation area (130). The hood apparatus is a concave-shaped structure, used for holding the head of a patient, an inhalation mask being accommodated inside the hood apparatus, and a plurality of inhalation holes being arranged on an internal side wall of the hood apparatus. A transparent part is arranged on the part of the hood apparatus facing the facial area of the patient. The air suction apparatus is provided with an air suction tube, the air suction tube being connected to the inhalation holes, and the air suction tube being used for extracting the air inside the hood apparatus by means of the inhalation holes. The present atomisation device, by means of the atomisation apparatus, the control apparatus, the hood apparatus, the air suction apparatus, the filter apparatus, and the bracket, reduces the amount of atomised particles of medicinal liquid dissipating externally, and can easily implement a remote control function.
