When the optical device is assembled with the atomizing component 2 and needs to swing, the optical device swings to the narrow side 141, the narrow side 141 cuts into the light path until the light path completely corresponds to the atomizing sheet 21, and the wide side 142 performs a reinforcing function and a limiting function on the position of the atomizing component 2. And in the swinging process, the optical device enables the light path not to be interfered except the part of the light through hole frame 14 through the depression 123 of the upper bottom plate 12 of the bracket 1, so that the atomization effect in the cutting process is improved. When the optical device is assembled with the prism assembly 3, the position of the support 1 is limited by the limiting plate 13, the wide side 142 and the like, the driving device 5 is driven by the motor to operate, and drives the third frame 33 of the prism assembly to spin, so that the prism sheet 31 spins, and various prism effects are brought. In addition to the optical unit, a pattern unit 10 (not shown) can be mounted, and the pattern unit 10 includes at least a connector 41 detachably connected to the holder 1.
