Abstract:

An aroma supply device (1) is configured such that a background aroma unit (106) and an odorless air unit (107) are inserted in parallel into a background aroma flow path, and a target aroma unit (109) and an odorless nitrogen unit (110) are inserted in parallel into a target aroma flow path. When only one of a first two-way valve (121) of the background aroma unit (106) and a second two-way valve (122) of the odorless air unit (107) is opened, air with a background aroma or odorless air flows out. When only one of a third two-way valve (123) of the target aroma unit (109) and a fourth two-way valve (124) of the odorless nitrogen unit (110) is opened, nitrogen with a target aroma or odorless nitrogen flows out. Further, the aroma supply device (1) switches and supplies the odorless air, the air with the background aroma, and the nitrogen with the target aroma by switching a three-way valve (202).
