A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

A shutter structure includes a rotary shaft, a shutter plate, an upper rib and at least one lower rib. The rotary shaft is provided in a cylindrical duct line. The shutter plate rotates about the rotary shaft and switches between an open state and a closed state. The shutter plate has a peripheral edge portion, a curved portion, and a shutter plate shaft portion. The peripheral edge portion includes an upper shielding plate and two lower shielding plates. The lower shielding plates are located symmetrically to each other with respect to a center line. The center line is perpendicular to the shutter plate shaft portion. When the shutter plate is in the closed state, the upper shielding plate comes into contact with the upper rib from an upstream side, and the lower shielding plates come into contact with the at least one lower rib from a downstream side.
