Abstract: An aroma-diffusing heating device includes a heating base, an aroma capsule detachably accommodated in the heating base and heatable by the heating base to give off fragrance, and a cap capped on the heating base over the aroma capsule. The aroma capsule includes a heat-transfer container defining a top opening, an aromatic substance held in the heat-transfer container, and a sealing film bonded to the heat-transfer container to seal the aromatic substance in the heat-transfer container.

Abstract: A pebble stone-shaped aroma diffuser includes a top cover shell, an upper panel, a gasket ring, a lower panel, a bottom cover shell, a heater and a base member. The gasket ring is tightly set between the top cover shell and the upper panel, thereby forming with the top cover shell and the upper panel a fluid container. The lower panel is supported on the bottom cover shell and closely attached to the upper panel of the fluid container. The heater is kept in contact with the bottom side of the lower panel. The base member is arranged at the bottom side of the bottom cover shell to provide power supply to the heater for producing heat that is transferred through the lower panel and the upper panel to heat the aromatic fluid in the fluid container. The fluid container is rapidly detachable from the lower panel for cleaning.
