[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scent generator for adding a scent to conditioned air or indoor air by leaking and vaporizing a small amount of liquid fragrance.

[0002]

2. Description of the Related Art Recently, scent air conditioning for giving a scent to an air-conditioned space has attracted attention, and various fragrances and scent giving means have been proposed. Among these, the method of spraying a fragrance using a spray nozzle is the most typical one in terms of the fragrance imparting means. In this case, the perfume is sprayed after being diluted with a solvent such as pure water or alcohol in order to control the perfume concentration to 1 ppm or less in the indoor air, which is said to be an appropriate perfume concentration.

[0003]

In the method of spraying fragrance into the air, there is a limit to the minimum amount that can be sprayed. Therefore, the liquid fragrance is diluted with a solvent or the like as described above and sprayed. Alcohols, which are excellent solvents, have a problem that they are dangerous.

In order to avoid this, the water is often diluted with pure water. However, the evaporation rate of the water is low, so that the water does not evaporate sufficiently and a problem of dripping occurs. There is the problem of increasing or causing humidity changes.

[0005] Furthermore, there are many oil-based flavors, but oil-based flavors are mixed with water because they are hard to mix with water.
Not very pleasant.

[0006] The present invention is intended to solve the above-mentioned problems when adding a scent to an air-conditioned space.

[0007]

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 a perfume leakage part, A minute variable flow rate pump interposed in the perfume conveying tube, an air blowing nozzle installed to blow air toward the perfume leaking section, and an air blowing nozzle
Compressed air source for sending compressed air to the
The above-mentioned perfume leaking part is arranged in a duct that carries air into the room.
And blow the above-mentioned air toward the perfume exposed part in this duct.
Provided is a scent generator configured to blow compressed air from an outlet nozzle .

[0008]

The micro-variable flow pump pumps the liquid perfume in the perfume container as it is (without diluting with a solvent, etc.) to the perfume leaking part at the end of the tube in a very small amount (0.01 to 120 ml / Hr). Thus, air is blown from the blowing nozzle to the liquid fragrance oozing little by little from the fragrance leakage part. The fragrance is volatilized by the air flow to obtain the scented air flow, and the scented air diffuses into the surrounding air to give a scent to the conditioned air.

An air blowing nozzle 9 is mounted in the duct 1 near the perfume leaking section 6, and an air flow is jetted from the air blowing nozzle 9 toward the perfume leaking section 6. The air blowing nozzle 9 is connected to a compressed air source 13 via an air tube 14. A high-performance filter 15 and a medium-performance filter 16 are interposed in the air tube 14, and the compressed air that has been cleaned through these filters is blown to the perfume leaking section 6. The compressed air source 13 may be a blower that sucks and discharges ambient air.

In the apparatus shown in FIG. 1 configured as described above, when the on-off valve 11 is opened to operate the minute variable flow rate pump 8 and clean air is blown from the air blowing nozzle 9 to the perfume leaking section 6,
The perfume liquid leaking little by little to the perfume leaking part 6 is sprayed, the vaporization is promoted by the air, and the perfumed air is diffused into the air flow in the duct. Therefore, the conditioned air flowing through the duct is appropriately perfumed and introduced into the air-conditioned space. When the scenting is stopped, the minute variable flow rate pump 8 acts as a check valve to prevent the fragrance staying in the tube 7 from flowing out to the fragrance leaking portion 6.
