[0007]

Since the present invention is constructed as described above, by operating the blower and opening a part of the solenoid on-off valve, the air discharged from the blower is transferred to some storage containers through the first pipe. After introducing the air, the scent emanating from the fragrance in the storage container is supplied to the air, and the air containing the scent is supplied through a common supply pipe . by opening the on-off valve of the bypass pipe, the bypass pipe only air discharged from the blower, the common supply pipe through the second pipe, or bypass
The air is directly introduced into the common supply pipe through the air supply pipe, and the air passing through the common supply pipe is discharged from the outlet. Thereafter, when supplying a gas containing another scent, the on-off valve is closed to shut off the bypass pipe, and air containing another scent that has passed through another storage container is supplied via the common supply pipe.
Thereby, when sequentially supplying various scents, by sending only air into the common supply pipe as described above,
The scent remaining in the common supply pipe can be removed.

Another bypass valve, for example, an electromagnetic switch valve 9 is provided in the bypass pipe 8. Have been. Although not shown, the blower 1 and the electromagnetic on-off valves 2A to 2C, 5A to 5C and 9 are controlled by control devices, respectively.

In this embodiment, the air blown from the blower 1 is guided to the storage container 4A through the first pipe 4 by operating the blower 1 and opening, for example, the electromagnetic on-off valves 2A and 5A. The air containing the fragrance emitted from the fragrance 3A in the storage container 4A is supplied to the air through the second pipe 5 and the common supply pipe 7, and the air is supplied from the outlet 6 to the room. Blow out. Next, when supplying another scent, while closing the above-mentioned electromagnetic on-off valves 2A and 5A and opening the electromagnetic on-off valve 9 of the bypass pipe 8, only the air discharged from the blower 1 is passed through the bypass pipe 8. Then, the air is guided into the common supply pipe 7, and the air passing through the common supply pipe 7 is discharged from the outlet 6 into the room.
