an aroma capsule detachably accommodated in said top accommodation open chamber and heatable by said heat conductive unit to give off fragrance;
said aroma capsule comprising a heat-transfer container accommodated in said top accommodation open chamber; and
said heat-transfer container defining a top opening, an aromatic substance held in said heat-transfer container, and a breathing film bonded to said heat-transfer container over the top opening to keep said aromatic substance in said heat-transfer container, said breathing film having open spaces defined therein.
2. The aroma-diffusing heating device as claimed in claim 1 , wherein said aroma capsule further comprises a sealing film bonded to said heat-transfer container over the top opening to seal said aromatic substance in said heat-transfer container and said breathing film under said sealing film.
3. The aroma-diffusing heating device as claimed in claim 2 , wherein said heat-transfer container of said aroma capsule comprises a rim extending around said top opening, and said sealing film is bonded to said rim of said heat-transfer container.
4. The aroma-diffusing heating device as claimed in claim 1 , wherein said heat-transfer container of said aroma capsule further comprises a rim extending around said top opening, and said breathing film has a border edge thereof bonded to said rim of said heat-transfer container.
5. The aroma-diffusing heating device as claimed in claim 4 , wherein said breathing film is one selected from the material group consisting of cloth, nonwoven fabric, fiber cloth, woven fabric, porous plastic membrane or porous silicon rubber.
6. The aroma-diffusing heating device as claimed in claim 1 , further comprising a cap capped on said heating base over said aroma capsule, said cap comprising an air vent.
7. The aroma-diffusing heating device as claimed in claim 1 , wherein said aromatic substance is an aromatic wax.
8. The aroma-diffusing heating device as claimed in claim 1 , wherein said heat-transfer container is an aluminum foil bowl.
9. The aroma-diffusing heating device as claimed in claim 1 , further comprising a light emitting diode circuit board mounted on said bottom cover and electrically connected to said power circuit board for emitting light.
10. The aroma-diffusing heating device as claimed in claim 9 , wherein said receiving unit is made of a light-pervious material selected from the group of transparent and translucent plastics, acrylic, glass and light-pervious ceramics.
11. An aroma capsule, comprising:
a heat-transfer container defining a top opening;
an aromatic substance held in said heat-transfer container; and
a breathing film bonded to said heat-transfer container over the top opening of said heat-transfer container above said aromatic substance in said heat-transfer container, said breathing film having open spaces defined therein.
12. The aroma capsule as claimed in claim 11 , further comprising a sealing film bonded to said heat-transfer container over the top opening to seal said aromatic substance in said heat-transfer container and said breathing film under said sealing film.
13. The aroma capsule as claimed in claim 11 , wherein said heat-transfer container comprises a rim extending around said top opening, and said breathing film is bonded to said rim.
14. The aroma capsule as claimed in claim 13 , further comprising a sealing film bonded to said rim of the heat-transfer container to seal said aromatic substance in said heat-transfer container and said breathing film under said sealing film.
15. The aroma capsule as claimed in claim 13 , wherein said breathing film has the border edge thereof bonded to said rim.
16. The aroma capsule as claimed in claim 11 , wherein said aromatic substance is an aromatic wax.
17. An aroma capsule, comprising:
a heat-transfer container defining a top opening;
an aromatic substance held in said heat-transfer container; and
a sealing film bonded to said heat-transfer container over the top opening to seal said aromatic substance in said heat-transfer container.
18. The aroma capsule as claimed in claim 17 , further comprising a breathing film bonded to said heat-transfer container over the top opening to seal said aromatic substance in said heat-transfer container and said breathing film under said sealing film.
