A micromist sauna device comprises: a circulating air supply device (11) for circulating indoor air, a heating device (12) for heating air, and a humidifier (20) arranged at the downstream side of the heating device (12) and used for humidifying air. The lower part of the humidifier is provided with a water storage portion (21) for storing water, and the upper part is provided with a humidification portion (22) for sucking up the water in the water storage portion (21) and spraying mist the humidification portion is a rotation body formed by a first drum (30) whose upper part is provided with an opening and a second drum (40) whose lower part is provided with an opening, the diameter of the first drum is larger than the diameter of the second drum, the first drum is communicated with the second drum, the first drum and the second drum have inclined surfaces expanded upwards and therefore are cone-shaped, the entire circumferential surface of the first drum is provided with multiple holes, and the humidification portion is integrally provided with an shaft fixing portion connected with a driving device of the humidification portion. The micromist sauna device can reduce vibration caused by imbalance of rotation of the first drum, the second drum, and two rotation bodies of the shaft fixing portion.La présente invention concerne un dispositif de sauna à micro-brouillard qui comprend : un dispositif dapprovisionnement en air circulant (11) pour faire circuler lair intérieur, un dispositif de chauffage (12) pour chauffer lair, et un humidificateur (20) disposé du côté aval du dispositif de chauffage (12) et utilisé pour humidifier lair.
