<Prior art> As a conventional fragrance dispersion device, for example, the Jikosho
No. 56-16968. This fragrance dispersion device immerses the lower end of the core material in a container containing a liquid fragrance, exposes the tip of the core material from the container, and sucks up the fragrance agent through the capillary action of the core material to store water-absorbing properties. The incense stick is impregnated with the incense stick, and a decorative umbrella is supported above the container, and the umbrella has a plurality of vent holes through which the fragrance emitted from the incense stick can pass.

<Problems to be solved by the invention> However, with the above-mentioned conventional fragrance dispersion device,
Since the natural emanation of the fragrance impregnated into the scent storage piece was utilized, the fragrance hardly emanates unless air flows over the surface of the fragrance storage piece. Therefore, the fragrance often does not emit air when it is needed, or emit air when it is unnecessary.

Furthermore, since the aromatic agent is stored in a liquid state in the container, it is troublesome to pour the liquid aromatic agent when replenishing the aromatic agent, and there is a risk that the liquid may spill and get on hands or the like.

<Means for Solving the Problems> Accordingly, the present invention provides an aromatic agent dispersion device comprising a base frame that removably supports an aromatic device, and a rotating body that covers the upper surface of the base frame, which A core material impregnated with an aromatic agent is stored in a container with an open top, and the aromatic device is supported such that the upper end of the core material contacts a water-absorbing mat member placed on the top surface of a base frame from below. ,
The rotating body is rotatably supported above the mat member by a detachable support shaft, and a ventilation hole is provided in the upper surface of the rotating body through which the fragrance emitted from the mat member can pass. A plurality of blades are arranged downwardly at the outer end of the mat member, and as the rotor rotates, outside air flows between the rotor and the mat member, and the fragrance is released. It is.

<Function> Therefore, the aromatic agent impregnated in the core material of the aromatic device is always diffused into the mat member by capillary action. Therefore, the aromatic agent that has permeated the mat member naturally emanates from the surface of the mat member and is released to the outside through the ventilation holes and between the blades of the rotating body, and the aromatic agent is released around the aromatic agent dispersion device. is drifting.

In addition to this, when the rotating body is rotated by hand around the support shaft, each blade forcefully causes outside air to flow between the rotating body and the mat member, thereby impregnating the mat member with an aromatic agent. The diffused aroma is released to the outside through the ventilation holes of the rotating body and between the blades, and the aroma of the aromatic agent is sufficiently wafted around the aromatic agent dispersion device.

Incidentally, when the aromatic agent impregnated in the core material is exhausted, the container containing the core material may be removed from the base frame and replaced with a new aromatic device.

The aromatic agent dispersing device 1 of the present invention has the above-described configuration, and the method of assembling the aromatic device 2, the base frame 3, the mat member 17, the rotating body 5, and the support shaft 14 is as follows.

First, align the center hole 18 with the shaft bearing part 13 of the base frame 3 and fit the mat member 17 into the upper surface of the base frame 3.
The mat member 17 is mounted by fitting the outer peripheral edge of the mat member 17 into the locking part 19 from the side.

Then, the three aromatic devices 2... are attached to the support part 9 of the base frame 3.
and are fitted into the storage parts 11 and 11, respectively.
When the aromatic device 2 is fitted into the support part 9 from below, the container 7
The upper outer periphery of the container 7 is firmly fitted into the annular step 10 of the support portion 9, and the container 7 is stopped at a position where the upper end surface 7' of the container 7 comes into contact with the upper end of the annular step 10. In this state, the aromatic device 2 is held such that the outer circumferential surface of the container 7 is in pressure contact with the circumferential surface of the annular stepped portion 10, and the upper end 6' of the core member 6 is connected to the mat member 17 through the opening 8. from below.

Further, the other aromatic devices 2', 2' are also fitted into the storage parts 11, 11 from below and supported as described above. The aroma device 2' supported in the storage section 11 is a spare one, and since the upper part of the storage section 11 is covered with the upper surface 4 of the base frame 3, the aroma device 2' is not stored in the core material 6 during storage. The agent will not volatilize.

Next, the flange 26 of the rotating body 5 is fitted into the shaft bearing part 13 of the base frame 3 from above, and the support shaft 14 is fitted.
The shaft portion 14b is inserted into the insertion hole 2 from the recess 24 of the knob 23.
5 and into the shaft hole 15 of the shaft bearing part 13. The shaft portion 14b of the support shaft 14 is crimped and supported from the periphery by a support protrusion 16 protruding into the shaft hole 15. 24. Therefore, the rotating body 5 is
It is supported above the base frame 3 so as to be rotatable about the shaft portion 14b.

In the assembled state as described above, it can be placed inside an automobile, placed inside a general house, or used by driving screws or the like through the mounting hole 21 of the collar 20 and attaching it to a wall surface or the like.

According to the device 1, since the upper end 6' of the core material 6 of the aromatic device 2 is in contact with the back surface of the water-absorbing mat member 17 from below, the aromatic agent impregnated in the core material 6 is caused by capillary action. It penetrates into the mat member 17 while being diffused. Therefore, the fragrance that permeates into the mat member 17 naturally emanates from the surface of the mat member 17 and enters the ventilation hole 28 of the rotating body 5 and the airfoil 30.
It is possible to emit the fragrance to the outside from the opposing spacing of the air fresheners, so that the aroma of the fragrance can be wafted around the device 1.

Also, if you want to increase the amount of fragrance released,
Pinch the outer peripheral surface 23' of the knob 23 of the rotating body 5 with your fingers,
The rotating body 5 may be rotated around the support shaft 14.
When the rotating body 5 rotates, the blades 30 rotate integrally with the rotating body 5, and due to the air intake or exhaust action of the blades 30 depending on the direction of rotation, the ventilation holes 28 of the rotating body 5 and the gap between the blades 30 facing each other are Outside air can be taken in from.
Therefore, the air on the surface of the mat member 17 flows, promoting the dispersion of the aromatic agent, and a large amount of air containing the aroma is released from the ventilation holes 28 of the rotating body 5 and between the blades 30, and It is possible to create a sufficient aroma from the air freshener in the surrounding area.

On the other hand, when the aromatic agent impregnated in the core material 6 has completely emanated, the aromatic device 2 supported by the support part 9 of the base frame 3 is pulled out from below, and a spare aromatic device 2'
It is only necessary to remove it from the storage part 11 and then fit it into the support part 9.

Furthermore, since the rotating body 5 and the base frame 3 are removable via the support shaft 14, if the spare fragrances 2', 2' attached to the base frame 3 are used up,
The support shaft 14 is pulled out together with the rotating body 5 from the bearing part 13 of the base frame 3, or only the support shaft 14 is pulled out individually, and the base frame 3 and the rotating body 5 are disassembled. Then, the removed base frame 3 is replaced with a new base frame to which a new fragrance device and mat member are attached, and the removed rotating body 5 is assembled to the new base frame using the support shaft. In this way, since the rotating body can be reused as is, it is not only possible to replace the fragrance device at a low cost, but also the trouble of fitting each fragrance device into the base frame can be saved.

In the above embodiment, the structure of the base frame 3 is such that three fragrances 2, 2', 2', including a spare one, can be attached to it, but it is also possible to attach at least one fragrance device 2 to the base frame 3. It's enough. Furthermore, although the blades 30 of the rotating body 5 are configured to be inclined at a certain angle with respect to the radial direction of the rotating body 5, the direction of inclination is not limited to that illustrated, and the angle of inclination is also extremely small. It's okay.

<Effects of the Invention> As described above, according to the present invention, by simply rotating the rotating body around the support shaft, outside air can be caused to flow between the rotating body and the mat member by the action of the blades.
It is easy to operate, and the introduction of outside air can promote the release of the aromatic agent from the mat member, allowing the aroma of the aromatic agent to be sufficiently dispersed around the aromatic agent dispersion device.

In addition, since we use an aromatic device with a core material impregnated with an aromatic agent stored in a container, it is extremely easy to replace the aromatic device, and there is no need to worry about spilling the aromatic agent when replacing it.
There is no risk of it getting on your hands.
