The buoy comprises a buoy body (10); the buoy body (10) comprises a panel (11) and a cavity (12) disposed in the panel (11); the cavity (12) is provided with a tubular structure (13) having an opening (131); the cavity (12) is provided with a communication hole (121) through which liquid enters the cavity. The aromatherapy machine comprises a housing in which a cavity for accommodating liquid is disposed, and the buoy described above is disposed in the cavity. The buoy body can float up and down with the liquid level, and can maintain a constant distance from the liquid surface. Even if the liquid level drops, the buoy body can be lowered with the liquid surface, so that fogging can be also performed normally at the high water level, and the atomization effect is enhanced. Moreover, the depth of the aromatherapy machine can be designed to be large, and the product is small and compact and occupies a small area. In addition, packaging and storage are facilitated, and low transport costs are achieved.
