DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fragrance device which is mounted on a device such as an air conditioner, an air purifier, a deodorizer, an oxygen enricher or an ozone generator and emits a scent into a room or a car. It is.

[0002]

2. Description of the Related Art Conventionally, there has been provided an air purifier in which a fragrance is disposed inside and an aroma is sent out by blowing air from a blower (see Japanese Utility Model Laid-Open No. 63-283648). By the way, the release of the fragrance may be performed only when necessary, and if the fragrance is released at all times, the odor of humans becomes dull, and the effect of the fragrance emission cannot be obtained.

In this air purifier, the fragrance is intermittently discharged by driving and stopping the blower using the fragrance which is always open, or the fragrance discharge hole of the storage container containing the fragrance is opened and closed. The fragrance is intermittently released by opening and closing by means.

[0004]

However, this air purifier has a drawback that the regulation of fragrance emission is insufficient. That is, in the former case, even if the blower is stopped, the fragrance is slightly released because the fragrance remains open. In the latter case, the fragrance discharge hole is closed by covering the fragrance discharge hole with a plate. However, depending on this plate, there is a problem that the storage container is not sufficiently sealed and a small amount of fragrance leaks out. Was.

On the other hand, since only a single fragrance can be attached to this air purifier, when it is desired to obtain a different fragrance, the fragrance must be replaced each time, and it is troublesome. There was also a problem. In order to solve such a problem, there has been provided an aroma device that selectively seals and opens a plurality of openable storage containers that respectively seal and store different fragrances (see, for example, Japanese Patent Application No. Hei. 2
305526 and Japanese Patent Application No. 2-30528).

[0006] In this fragrance device, each storage container is arranged on the turning locus of a single cam erected on the upper surface of the rotating body, and the storage container is opened by contact of the cam.
The storage container is closed by the separation of the cam. However, on the turning trajectory of a single cam,
Due to the arrangement of a plurality of storage containers, this fragrance device required a certain depth.

On the other hand, there is a case where a thin fragrance device having a small depth is required due to a demand for a mounting space inside a device to be mounted on which the fragrance device is mounted. Was unable to respond to such a request. An object of the present invention is to solve the above technical problems,
An object of the present invention is to provide a thin fragrance device that can selectively emit a plurality of fragrances and reliably control fragrances.

[0008]

According to a first aspect of the present invention, there is provided a fragrance device, wherein a plurality of fragrance devices are fixed along the axial direction of a rod with their rotational phases shifted from each other. A plurality of storage containers each containing a different fragrance, which are provided corresponding to each of the cams, are provided corresponding to the respective cams, and are opened by contact of the cams and closed by separation of the cams, and the rod is rotated. A drive means for driving, and control means for controlling rotation of the rod by the drive means so as to selectively open each storage container are provided.

[0009]

According to the above construction, by rotating the rod and selectively opening each storage container by the cam,
It is possible to easily emit a desired fragrance without replacing the fragrance in the storage container as in the related art. Further, the fragrance does not leak from the storage container which is selectively closed.

Further, since a plurality of cams are fixed along the axial direction of the rod, and the storage containers are provided corresponding to the respective cams, the plurality of storage containers are arranged in the axial direction of the rod. The depth of the fragrance device can be reduced.
