Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for generating a required scent.

INDUSTRIAL APPLICABILITY The scent generating device of the present invention is used when a scent is dissipated in a theater according to video or music.

[Background Art] A device is commercially available in which a container filled with a fragrance such as a flower that emits a fragrance is placed in a room, and the scent radiating from the container makes the room a comfortable atmosphere. The container is open to the open air, and the fragrance emits a scent to the surroundings by evaporation or sublimation.

[Problems to be Solved by the Invention] The sense of smell varies greatly among individuals, and it is desirable to adjust the intensity of the scent according to the preference of each individual. However, since the conventional scent generating device was merely filled in a container opened to the outside air, the intensity of the scent could not be adjusted.
Further, there is also a problem that the fragrance is weakened when the fragrance is reduced.

Further, the conventional scent generating device emits only one kind of scent, and it was not possible to emit various scents according to taste or situation.

Therefore, an object of the present invention is to provide a scent generator capable of adjusting the intensity of a scent to a desired intensity and further selecting a desired scent from a plurality of scents.

Means for Solving the Problems The scent generating device of the present invention is installed in a theater and has a plurality of hermetic fragrance containers containing fragrances, a compressed air supply device connected to the entrance side of each fragrance container, and a fragrance container. It has a scent emission nozzle connected to the outlet side, and a switching valve and a flow control valve provided between each fragrance container and the scent emission nozzle. The scent-dissipating nozzle is mounted on the seat to supply the scent to the audience in the back row seat. A large number of air vents on the floor that supply fresh air to the audience with ventilators,
Further, a large number of exhaust holes for discharging the remaining scent are provided in the ceiling, respectively, and a control device is provided for controlling the switching of the switching valve and the supply of air from the ventilation device according to the situation.

The fragrance is selected depending on the purpose such as a flower (for example, rose and jasmine), a drink (for example, coffee), or a fragrance of a dish (for example, curry). The fragrance may be any of a lump, a granule, a powder, and a liquid. If the fragrance is in the form of granules or powder, store it in a cloth or mesh bag so that it does not get caught in the air flow.

The perfume container needs a flow path sufficient for compressed air to flow through the inside of the container, in addition to the space for filling the perfume. When there are a plurality of fragrance containers, each container is filled with a different fragrance. One container may be airtightly partitioned, and a plurality of fragrance containers may be integrated.

The compressed air supply device includes an air compressor, a tank, a manifold, and piping associated therewith.

The scent-dissipating nozzle is opened in a round hole or a slit shape, and is arranged in a theater audience seat.

As the switching valve, a two-way solenoid valve, a manual stop valve, or the like is used.

[Action] When the compressed air passes through the perfume container, it comes into contact with the perfume,
It is blown out from the scent dispersing nozzle with the fragrance vapor or sublimation gas. The amount of the compressed air including the vapor of the fragrance or the sublimation gas is adjusted by the flow rate control valve to adjust the intensity of the fragrance. The scent is strong when the blowing amount is large, and weak when the blowing amount is small.

The control device switches the switching valve according to the situation such as video or music to select a required scent.

[Embodiment] FIGS. 1 to 4 show an example in which the scent generator of the present invention is applied to a theater.

As shown in FIG. 1, the scent generator is mainly composed of an air system 11 and an electric system 31.

Equipment placed in the theater is sub tank 15, main manifold
16 others. Subtank 15 and main manifold 16
Are provided for each of a plurality of seats (for example, 10 seats). The main tank 13 supplies compressed air to the sub-tank 15 via a pipe 14. The main manifold 16 is on the exit side of the sub tank 15
Are connected, and the number of branch pipes 17 of the main manifold 16 is
The number of seats served by primary manifold 16 (in this example,
10 seats). A sub-manifold 19 is connected to each branch point 17 of the main manifold 16, and the sub-manifold 19 is arranged at each seat. The sub-manifold 19 has five branch pipes 20, and each branch pipe 20 has a check valve 21, a fragrance container 22,
A one-way solenoid valve 25 and a flow control valve 26 are sequentially mounted. The check valve 21 prevents backflow of air from the perfume container 22 to the sub-manifold 19, and prevents mixing with other types of scents. The fragrance container 22 stores a hollow cylindrical bag 23 (see FIG. 2) made of a mesh filled with granular fragrance.

FIG. 2 shows the devices arranged in each seat 51.
In this embodiment, since the equipment is arranged on each seat 51, the two-way solenoid valve 25 and the flow control valve 26 are integrated as a unit in order to make the apparatus compact. Each flow control valve 26
The flow rate is adjusted in advance according to the type of scent and the intensity of the scent given to the audience. On the outlet side of each of the flow control valves 26, a scent releasing nozzle 28 is attached via a pipe 27. The piping 27 is designed so that no scent remains inside.
It is as short as possible. Five scent emission nozzles 28
It is covered by a hood 29. The hood 29 is open so that the scent P diverges toward the audience A as shown in FIG. In this embodiment, five types of scents can be emitted.

As shown in the schematic diagram of FIG. 1, the electrical system 31 comprises a decoder 32 for reading out the recorded control signal together with the audio signal.
It has. On the output side of the decoder 32, a sequencer 33, a solenoid valve drive section 34, and a two-way solenoid valve 25 are sequentially connected. Further, the ventilation control device 36 for controlling the ventilation device 49 is connected to the sequencer 33. Note that the two-way solenoid valve 25 and the ventilation device 49 can also be operated by the manual switch 39, respectively.

FIG. 4 shows the entire theater 41 equipped with the above-mentioned scent generating device.
