More preferably, the air duct 3b4 is arranged on the side wall of the bracket 3b, the upper end opening 3b5 of the air duct 3b4 is covered by the sealing gasket 3a2, and the lower end opening 3b6 is opened, so that when the atomized liquid in the liquid storage bin is reduced, air can be supplemented into the liquid storage bin in time. More preferably, the air passage 3b4 is configured to be a zigzag shape, which increases the length of the air passage 3b4 and narrows the aperture of the air passage, so that even if a small amount of atomized liquid leaks into the air passage from the opening 3b5, the atomized liquid cannot flow out of the air passage due to the viscosity of the atomized liquid, and the leakage of the atomized liquid is avoided.
