Description

[Detailed description of the device]

[0001]

[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 indoor air, which is said to be an appropriate perfume concentration, it is common to dilute the perfume with a solvent such as pure water or alcohol before spraying.

[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.

[0006] On the other hand, there is a heating type mosquito coil incense that vaporizes a drug using a heater. For example, it is known that the vaporization of liquid mosquito coil is promoted by a heater, but if this is applied to perfume with liquid fragrance, the following disadvantages occur. That is, although the volatilization amount of the fragrance can be controlled by the heating value of the heater, it cannot be stopped immediately and the volatilization amount cannot be suppressed below a certain amount. This is because even if the power to the heater is stopped, it does not cool immediately, and even if it cools, there is spontaneous volatilization.

[0007] The present invention is intended to solve the above-mentioned problems in imparting a scent to an air-conditioned space.

[0008]

[Means for Solving the Problems]

 According to the present invention, a perfume container containing a liquid perfume, a liquid perfume transport tube having one end inserted into the perfume container and the other end connected to the perfume leaking part, and the liquid perfume container is provided on the transport tube. The fragrance leaking part can be opened and closed by the liquid-impregnated core, the heater that heats the core, the container that shuts off the core from the ambient atmosphere, and the container. Provided is a scent generating device configured with a lid attached to.

[0009]

[Action]

 The micro 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 (about 0.01 to 120 ml / Hr). In the perfume leaking part, the liquid perfume is impregnated in the core part by a capillary phenomenon. By heating this core with a heater, the impregnated liquid flavor is vaporized.

On the other hand, this core is installed in a container that shields it from the surrounding atmosphere, and the opening and closing of the lid attached to this container performs the operation of turning on and off the aroma. By performing the opening / closing operation of the lid following the starting / stopping operation of the heater, it is possible to add and stop the scent to the atmosphere reliably and easily. In addition, the aroma concentration can be controlled by controlling the amount of electricity supplied to the heater.

It is equipped with a tube 5 and a minute flow rate pump 6 interposed in the tube 5 for carrying the fragrance.

The perfume container 3 is a bottle for hermetically containing the liquid perfume 2. A tube 5 for drawing out the liquid perfume and an air inlet pipe 16 with a check valve are hermetically penetrated through the lid of the container 3. ing. The air inflow pipe 16 is for alleviating the pressure reduction in the container due to the liquid perfume pumping out. An open / close valve 17 is attached to the tube 5.

In the illustrated example, the micro flow pump 6 is attached to a tube 5 near the scent leaking portion 4, and the pump 6 serves as a check valve while the pump is stopped. The micro flow pump 6 is a device available on the market. In the illustrated example, a roller that unidirectionally pushes the liquid inside the tube while sandwiching the flexible tube from the outside is used. I am using a pump. The roller is rotated by a motor, but the amount of extruded liquid can be finely adjusted by adjusting the rotation speed of the roller. In addition to the roller pumps, there are also micro flow pumps 6 available on the market as described above, which are called tube pumps and diaphragm pumps. In any case, this pump should be capable of controlling the flow rate within the range of 0.01 to 120 ml / Hr.

As shown in FIG. 2, the fragrance leaking portion 4 includes a liquid-impregnating core portion 7, a heater 8 for heating the core portion 7, a container 9 for shutting off the core portion from an ambient atmosphere, and this container.
