Olfactory display and fragrance source cartridge used therein
View Patent ↗An olfactory display 10 includes a display main body 12 and a fragrance source cartridge 14 , and presents a fragrance to a range bounded in terms of time and space. A cartridge accommodation room ( 24 ) of the display main body 12 and a container main body ( 80 ) of the fragrance source cartridge 14 are formed with inclined surfaces 46 and 84 inclined with respect to an insertion direction of the fragrance source cartridge 14 , and a force that pushes in the fragrance source cartridge 14 acts in a direction that an open air inlet 82 is pressed to an air supply port 54 side. Accordingly, adhesiveness of a coupling portion of the air supply port 54 and the open air inlet 82 increases, and therefore, capability of an airflow source 26 is used to the utmost, and a high static pressure is generated in the fragrance source cartridge 14 for a short time.
1. An olfactory display that includes a display main body and a fragrance source cartridge, and presents a fragrance within a range bounded in terms of time and space, wherein
the display main body comprises
a housing having an emission port in a center portion in a front side;
a plurality of cartridge accommodation rooms that are formed by dividing an internal space of the housing by radial partitions, each of the cartridge accommodation rooms having an air supply port and an air discharge port;
a communicating hole that is provided in the housing to make respective air discharge ports communicate with the emission port;
cartridge exchange portions each formed in each of the cartridge accommodation rooms; and
a plurality of airflow sources that are provided in the cartridge accommodation rooms, each of the airflow sources sending an air into the inside of the fragrance source cartridge that is accommodated in the cartridge accommodation room from the air supply port with using a diaphragm having a piezoelectric device, and
each of the fragrance source cartridges comprises
a container main body that has an outer shape conformed to an inner shape of the cartridge accommodation room, and is formed with an air inlet in a position corresponding to the air supply port and a fragrance outlet in a position corresponding to the air discharge port; and
a solid-like fragrance source stored within the container main body, and
the inner shape of the cartridge accommodation room and the outer shape of the container main body respectively have inclined surfaces inclined with respect to an insertion direction of the fragrance source cartridge.
2. The olfactory display according to claim 1 , wherein the airflow source is arranged to constitute a part of the partition, and the air supply port is formed on the partition, and
the cartridge exchange portion is formed on a side wall of the housing.
3. The olfactory display according to claim 1 , wherein the airflow source is arranged to constitute a part of the partition, and the air supply port is formed on the partition, and
the cartridge exchange portion is formed on a front wall or a rear wall of the housing.
4. The olfactory display according to claim 1 , wherein the airflow source is arranged to constitute a part of a side wall and the air supply port is formed on the side wall, and
the cartridge exchange portion is formed on a front wall or a rear wall of the housing.
5. The olfactory display according to claim 1 , further comprising a cover that is provided in the cartridge exchange portion and pushes the fragrance source cartridge in the insertion direction when the fragrance source cartridge is accommodated in the cartridge accommodation room.
6. The olfactory display according to claim 1 , wherein the emission port is formed in a plural number in a center portion at the front side of the housing, and
each of the air discharge port is communicated with corresponding one of the emission ports via an individual communication hole.
7. The olfactory display according to claim 1 , further comprising an auxiliary airflow source that is provided in the housing and has a diaphragm provided with a piezoelectric device.
8. A fragrance source cartridge used in the olfactory display according to claim 1 , comprising:
a container main body that has an outer shape conformed to an inner shape of the cartridge accommodation room, and is formed with an air inlet in a position corresponding to the air supply port and a fragrance outlet in a position corresponding to the air discharge port; and
a solid-like fragrance source stored within the container main body, wherein the outer shape of the container main body has inclined surfaces inclined with respect to an insertion direction of the fragrance source cartridge.
