Description

Card type olfactory display device {THE CARD TYPE OLFACTORY DISPLAY DEVICE}

The present invention relates to a card-type olfactory display device, and more particularly, the air flow path inside the aroma card and the aroma card composed of a plurality of small chips coated with a substance blended with a functional polymer to smooth the flow of aroma. A card type olfactory display device is provided.

Human beings lead daily life through the five senses, and the five senses are used integrally in communication activities. In addition, with the development and dissemination of various media such as a TV or a PC, information of a remote location can be easily acquired in the present age. In other words, it is no exaggeration to say that today's media is fulfilling its role as the concept of 'expansion of sense' in our daily lives.

However, these media are basically based only on audiovisual information, and it cannot be said that they convey the feeling sufficiently in the field atmosphere reproduction that gives a feeling of being in the field.

Therefore, in recent years, information and communication technology research and development that can obtain a 'high sense of presence' and 'high immersion' by expressing the on-site atmosphere more realistically than before is being rapidly promoted.

In particular, research and development on the presentation of olfactory information has been promoted beyond the scope of conventional visual / audio / tactile technologies, and various olfactory displays have been proposed. For example, many systems have already been proposed, such as those used in movie theaters, such that when a specific link is clicked on a website on the Internet, a direction generator, which was previously connected to a PC, is activated to generate fragrance according to the clicked content. It is built.

However, studies related to olfactory displays, in which sensory receptors detect and recognize chemical changes, are still insufficient and include many problems. Moreover, in the case of odor, basic elements such as the three primary colors of light have not been found. Therefore, the realization of a general-purpose device capable of steering and emitting odors representing a specific substance or environment in accordance with the contents such as video or sound As a result, a large number of fragrant sources need to be prepared, making them large and expensive.

Therefore, it is difficult to introduce such a device into the home at present, and since the existence of the original smell is unclear, the miniaturization of the olfactory display is extremely difficult and the price of the olfactory display is extremely difficult to be realized in the future.

Then, in order to solve this problem, the non-universal (fragrance exchange) system which proposes the specific direction circle prepared previously according to content, such as an image or a sound, is proposed in large quantities.

As a specific example, a variety of companies, including AromaJet, Scentair, and TriSenX in the United States, Aerome in Germany, and OSMOOZE in France, participate in the fragrance presentation system based on specific contents connected to a PC. Doing.

In Japan, air compressors such as Aiba, Fragra such as Mochitsuki, wearable olfactory displays such as Hirose, and odor combination devices such as Yamanaka. Many research institutes and companies are participating in this research, including Aroma Juru, which has been commercialized for odor recording / regeneration systems, and Airborne Olfactory Displays such as Yanagida.

In Korea, a variety of systems have been proposed, such as the fragrance cell phone of UN-I, the embedded expression device for aroma solution, and the S / E Tech's fully automatic fragrance system for indoor / vehicle. .

On the other hand, the existing olfactory display was difficult to miniaturize / cheapen with the complexity of the fragrance source exchange. In addition, there were problems in handling and dissemination. Research and development to solve these problems is also actively underway. Various physicochemical principles are used because chemicals are released in certain environments at constant controlled rates.

Representative principles of emission control include dissolution, ion exchange, infiltration pressure, vapor pressure, physical force contraction force) with diffusion, dissolution and decomposition. Using these principles to control drug release requires the use of functional materials. Functional materials used for emission control include viscous minerals widely used as porous materials and various polymers used for drug control. Controlled release using these principles and materials include pharmaceuticals, pesticides, detergents, cosmetics, and deodorants.

In particular, a system that performs directional control using a functional material in synchronization with contents such as a moving picture or sound includes applying a microencapsulated fragrance component to a card or sheet on a powder or slurry in a specific device, such as thermal collapse or compression collapse. Many techniques have been proposed to control the direction in accordance with moving images or sound contents by decomposing or light decay.

By using the gel or capsule as described above, there is an advantage that the handling and convenience is maximized compared to the liquid. However, the gel state has a sustained release effect, but requires a special control release device in order to release the required amount in accordance with the purpose when needed. As a result, there are many difficulties in miniaturizing the system as well as the noise problem caused by the device setting.

On the other hand, the application of the encapsulated aroma component to a card or sheet on a powder or slurry is applied to a specific area in the case of a method of controlling the direction according to a moving image or acoustic content by thermal breakdown, pressure breakdown or light breakdown within a specific window. Due to the specific nature of the capsules in a given aroma source, there is a limit to the number of aroma sources that can be represented since there is only one compatibility limit.

In addition, even when using a tape-like method such as a fragrance device and a deodorizing device (Japanese Patent Laid-Open No. 2004-81378), a device such as a roll must be installed for scenting, so that it is not only physically constrained to miniaturize, but also noise. Problems also arise. In addition, there is a problem in that it is not possible to cope with playing a specific place by playing or fast forwarding.

As described above, the conventional olfactory display has various problems such as miniaturization, low cost, handling, and noise. In addition, in the structure of the olfactory display, if there is any device (blower, cover, passage, etc.) in front of the flow path of the fragrance molecule, the fragrance adheres to the surface thereof, and it is a problem that the original fragrance information is not properly expressed by mixing with the fragrance previously presented. Occurs. All olfactory display devices designed so far suffer from this problem.

The present invention has been made in view of the above problems, an aroma card comprising a large number of small chips coated with a substance mixed with a perfume to a functional polymer causing a phase change in a sol state or gel state according to the temperature state, and aroma Its purpose is to provide a card-type olfactory display device having an air flow path formed therein to facilitate the flow of the card fragrance.
