[Industrial applications]

 The present invention relates to a scent generation device for adding a scent to air-conditioned air or indoor air by leaking and vaporizing a small amount of liquid fragrance.

[0002]

[Prior Art]

 Recently, scent air conditioning, which gives scents to air-conditioned spaces, has attracted attention, and various fragrances and scent applying means have been proposed. Of these, the method of spraying the fragrance using a spray nozzle is the most representative of the scent imparting means. In this case, in order to control the perfume concentration to be 1 ppm or less in the room air, which is said to have an appropriate perfume concentration, the perfume is diluted with pure water or a solvent such as alcohol and then sprayed.

[0003]

[Problems to be solved by the device]

 In the method of spraying the fragrance into the air, since the minimum amount that can be sprayed is limited, the liquid fragrance is diluted with a solvent as described above and sprayed. Alcohols, which are the most typical solvents, are dangerous. There is a problem with.

In order to avoid this, it is often diluted with pure water, but since the evaporation rate of water is slow, the problem of dripping occurs due to insufficient evaporation, and water spraying has a latent heat load. It is accompanied by the problem of increased temperature and changes in humidity.

Although many of the fragrances are oil-based, oil-based fragrances are difficult to mix with water, so they are mixed with a surfactant. However, the surfactants blow out into the living room. It's not very pleasant.

The present invention is intended to solve the above-mentioned problems in imparting a scent to an air-conditioned space.

[0007]

[Means for Solving the Problems]

 According to the present invention, a perfume container containing a liquid perfume, a perfume transport tube having one end inserted into the perfume container and the other end connected to the perfume leaking part, and the perfume transport tube provided with the perfume transport tube. Provided is a scent generation device comprising the minute variable flow pump described above and an air blowing nozzle installed so as to blow air toward the fragrance leaking portion.

[0008]

[Action]

 The micro variable flow pump conveys the liquid perfume in the perfume container as it is (without diluting it with a solvent etc.) to the perfume leaking part at the end of the tube in very small amounts (0.01 to 120 ml / Hr). By this, air is blown from the blowing nozzle to the liquid fragrance that oozes out little by little from the scent leaking part. The perfume volatilizes by this air flow and this perfume air flow is obtained, and the perfume air diffuses into the surrounding air and imparts a scent to the conditioned air.
