The invention discloses a micro-fog sauna device, which comprises a circulating air supply device, a heating device and a humidification device, wherein the circulating air supply device is used for circulating indoor air the heating device is used for heating the air the humidification device is arranged on the downstream side of the heating device, and is used for humidifying the air a water storage part for storing water is arranged on the lower part of the humidification device, and a humidification part for sucking the water stored in the water storage part and performing spraying is arranged on the upper part of the humidification device the humidification part is a rotating body consisting of a first barrel and a second barrel, an opening is formed in the upper part of the first barrel, and an opening is formed in the lower part of the second barrel the diameter of the first barrel is greater than that of the second barrel the first barrel is communicated with the second barrel the first and second barrels are gradually enlarged from the lower parts to the upper parts to form circular cones a plurality of holes are formed in the whole circumferential surface of the first barrel. The micro-fog sauna device has the advantage that humidification loss and heat loss can be reduced.
