MIST GENERATION DEVICE

This invention is capable of preventing device failure, while allowing an impeller rotation to be fixed at a desired speed, and allowing a mist of an intended diameter to be obtained. This mist generation device comprises: a casing 11 equipped with a water tank 12; a heater 19 for the purpose of heating the water inside the water tank; a shaft part 13 provided inside the casing and extending in the vertical direction; a motor 13c connected to the shaft part; an impeller 14 installed on the shaft part in such a manner as to be rotatable horizontally by the motor, with the shaft part serving as the rotation axis; a nozzle 15 ejecting the water from the water tank toward the impeller; and a pump 21 sending the water from the water tank to the nozzle. The impeller is constituted in such a manner as to comprise a plurality of blades 14a that are disposed along the impeller rotation direction and impinged by the water ejected from the nozzle such that by way of the water ejected from the nozzle impinging on the bla
