DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an air freshener dispersion device that can be placed inside an automobile, inside a house, or hung on a wall.

<Prior art> As a conventional fragrance dispersion device, for example,
This is shown in Japanese Patent No. 6968. This fragrance dispersion device immerses the lower end of the core material in a container containing a liquid fragrance.
The tip of the core material is exposed from the container, and the capillary action of the core material sucks up the aromatic agent and impregnates it into the water-absorbing culture piece.A decorative umbrella body is supported above the container, and the umbrella body has a It is constructed by opening a plurality of ventilation holes through which the aroma emitted from the cultured pieces can pass.

<Problems to be solved by the invention> However, in the above-mentioned conventional fragrance dispersion device, since the natural emission of the fragrance impregnated into the cultured pieces was utilized, air did not flow over the surface of the cultured pieces. As long as it does not emit much fragrance. Therefore, the fragrance often does not emit when necessary or emit when it is unnecessary.

Furthermore, since the aromatic agent is stored in a liquid state in the container, it is troublesome to pour the aromatic agent into the container 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> Therefore, the present invention provides a base frame that removably supports an aromatic device,
and a rotating body that covers the upper surface of the base frame, and the aromatic device has a core material impregnated with an aromatic agent stored in a container with an open top surface, and the aromatic device is attached to the upper end of the core material. supports the water-absorbent mat member placed on the upper surface of the base frame so as to contact it from below, and rotatably supports the rotating body above the mat member with a removable support shaft. A ventilation hole is provided on the top surface through which the fragrance emitted from the mat member can pass, and a plurality of blades are connected downward at the outer end of the rotating body, so that the rotation of the rotating body causes the rotation of the rotating body. The feature is that outside air is allowed to flow in between the mat member and the fragrance to be released.

Effect> Therefore, the aromatic agent impregnated into the core material of the aromatic device is always diffused into the mat member by capillary action. Therefore, the fragrance 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 fragrance caused by the fragrance is distributed around the fragrance 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 discharged 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.

According to the device 1, since the upper end 6' of the core material 6 of the aromatic device 2 contacts the back surface of the water-absorbing mat member 17 from below, 1, the aromatic agent impregnated in the core material 6 causes capillary action. As a result, it permeates into the mat member 17 while being diffused. For this reason,
The aromatic agent permeated through the mat member 17 naturally emanates from the surface of the mat member 17 and is released to the outside from the ventilation hole 28 of the rotating body 5 and the opposing spacing between the blades 30, and the aromatic agent is spread around the device 1. It can give off a scent.

Also, if you want to increase the amount of fragrance released.

The rotating body 5 may be rotated about the support shaft 14 by pinching the outer circumferential surface 23' of the knob 23 of the rotating body 5 with fingers.

When the rotating body 5 rotates, the blades 30 rotate integrally with the rotating body 5, and due to the intake or exhaust action of the blades 30 depending on the direction of rotation, the airflow through the ventilation hole z8 of the rotating body 5 or within the opposing interval between the blades 30 occurs. 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 the spare aromatic device 2' is placed in the storage section 11. All you have to do is remove it from the holder and fit it into the support part 9.

In addition, since the rotating body 5 and the base frame 3 are removable by the support shaft 14, if the spare fragrances 2', 2' attached to the base frame 3 are used up, the base frame 3 can be replaced. Shaft bearing part 13
Either pull out the support shaft 14 along with the rotating body 5 from the
The body is pulled out individually and disassembled into the base frame 3 and the rotating body 5. Then, the removed base frame 3 can be replaced with a new base frame equipped with a new aromatic device and mat member, and the removed rotary body 5 can be assembled to a suitable base frame using the support shaft. Since the rotating body can be reused in its entirety, 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-mentioned embodiment, the structure of the base frame 3 includes three fragrances, including a spare one. , 2', 2' can be attached, but it is sufficient if the structure is such that at least one aromatic device 2 can be attached. Furthermore, although the blades 30 of the rotor 5 are inclined at a certain angle with respect to the radial direction of the rotor 5, the direction of inclination is not limited to that shown in the drawings, and the angle of inclination is also extremely small. It's okay.

<Effects of the Invention> According to the present invention, by simply rotating one 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, and the operation is easy. It is simple, and the introduction of outside air can promote the release of the fragrance from the mat member, and the aroma of the fragrance can be sufficiently dispersed around the fragrance dispersion device.

In addition, since we use a fragrance device with a core material impregnated with an aromatic agent stored in a container, it is extremely easy to replace the fragrance device, and there is no risk of spilling the fragrance or getting it on your hands when replacing it. do not have.
