The present invention relates to scent releasing and heating devices and more particularly, to an aromatherapy device with an aroma diffuser, which allows a disposable multilayer breathing film-based aroma capsule and a detachable aromatic substance container to be used interchangeably according to user preferences, so the multiple choices of aromatic substances are not limited.
In prior art aroma diffuser designs invented by the present inventor, such as U.S. Pat. Nos. 8,668,885, 9,550,358, 9,498,533, EP Pat. No. 2679249, a container is used to transmit a heat source to an aromatic substance. The aromatic substance is heated in the middle and the other part of the aromatic substance is far away from the heat source. The fragrance is only generated in the middle part of the aromatic substance, so it is less easy to produce a sufficient amount of fragrance instantly, and you need to wait a long time to smell the fragrance. And the heat source is concentrated in the central part of the aromatic substance, it is difficult to completely vaporize the aromatic substance, and the residual aromatic substance is often formed to waste.
In the existing aroma diffuser designs, the heating container that houses the aromatic substance is a fixed structure. For example, it is a metal container fixed to the aroma diffuser. The interior of the metal container is filled with an aromatic substance, so the use of aromatic substances and the replacement of aromatic substances are limited.
The present invention has been accomplished under the circumstances in view. It is thereof the main object of the present invention to provide an aromatherapy device with an aroma diffuser, which evenly disperses heat source through the aromatic substances for producing fragrance, enabling the aromatic substances to be completely vaporized without leaving a residue.
It is another object of the present invention to provide an aromatherapy device with an aroma diffuser, which allows a disposable multilayer breathing film-based aroma capsule and a detachable aromatic substance container to be used interchangeably according to user preferences, so the multiple choices of aromatic substances are not limited.
To achieve these and other objects of the present invention, an aromatherapy device comprises an aroma diffuser. The aroma diffuser comprises a connection device, a fixing device set, a hollow heating element, a thermal conduction device, a shell and a base.
