The diffusion member 4 and the recess 2 are located above the upper lid 22.
A transparent cap 6 is detachably fitted so as to cover 2a. The cap 6 is formed in a substantially inverted cup shape.
Is sealed.

Next, a method of using the diffuser 1 according to this embodiment will be described with reference to FIG. FIG. 4 shows the diffuser 1 in a state where the cap 6 and the diffusion member 4 are not attached to the upper lid 22 as an example. In the diffuser 1, first, the incandescent lamp 5 is press-fitted into the upper protruding portion 22b so that the incandescent lamp 5 is accommodated in the fitting hole 42 of the diffusing member 4. Next, the lid of the bottle 7 containing the liquid aromatic substance (aroma oil) 71 is opened, and an appropriate amount of the aromatic substance 71 is dripped toward the diffusion member 4 to impregnate the diffusion substance 4 with the aromatic substance 71. Note that the aromatic substance 71 may be poured into the recess 22 a of the upper lid 22 so that the diffusion member 4 is impregnated with the aromatic substance 71. The aromatic substance 71 is not limited to aroma oil (essential oil containing an extract such as peppermint and rosemary), and any aromatic substance can be used as long as it is a liquid substance. After the operation of impregnating the aromatic substance 71, the cap 6 from which the stopper 62 has been removed is covered from above the upper lid 22.

When such preparations are completed, the apparatus is installed in a room where fragrance is performed, for example, in a living room of a general house or in a car, and the power switch 26 is turned on. Here, when connected to an external power supply through the plug 27, power is supplied from the external power supply to each of the devices 5 and 31. On the other hand, when not connected to the external power supply, the power is supplied from the battery 32 to each of the devices 5 and 31. Is supplied. The air supply pump 31 is driven by this power supply, and the incandescent lamp 5 emits light.

By driving the air supply pump 31, air around the diffuser 1 flows into the casing 2 through the air holes 24 and 25, and the inflow air is supplied to the air filter 37.
Then, dust is removed, and the air is further sucked into the air supply pump 31 sequentially through the filter socket 37a and the suction passage 36a. The sucked air is compressed by the air supply pump 31 and blown out to the discharge passage 36b.

As shown by arrows in FIG. 5, the air blown out to the discharge passage 36b is supplied to each of the projections 22b, 22b.
c, and flows into the diffusion member 4 through the slit 22d. Here, since the diffusion member 4 is heated by the light emitted from the incandescent lamp 5, the aromatic substance 71 impregnated in the diffusion member 4 is vaporized or easily vaporized. That is, the incandescent lamp 5 has a function of promoting the vaporization and further diffusion of the aromatic substance 71. Further, the air supply pump 31 forcibly supplies air to the diffusion member 4,
1 and has a function of forcibly diffusing the vaporized aromatic substance 71.

Due to the functions of the two diffusion accelerators 5 and 31, a large amount of the aromatic substance 71 is mixed into the air flowing into the diffusion member 4, and the mixed air is mixed with the pores and the elongated holes 4 of the diffusion member 4.
1 is blown out to the cap 6 side. The mixed air blown out to the cap 6 side is blown out of the diffuser 1 through the blowout hole 61 and diffused into a room or the like.

On the other hand, when the diffuser 1 is not used, the power switch 26 is turned off, and the outlet 61 of the cap 6 may be sealed with a stopper 62 as shown in FIGS.

According to the present embodiment, the aromatic substance 71 impregnated in the diffusion member 4 is heated by the incandescent lamp 5 and is forcibly supplied to the room or the like by the air supply pump 31. The whole can be aroma.

Further, since the diffusion member 4 has the elongated holes 41, the liquid aromatic substance 71 impregnated in the diffusion member 4 is forcibly blown out in a mist state by the air passing through the elongated holes 41, and is diffused. The aromatic substance 71 does not remain in the member 4, thereby preventing the diffusion member 4 from being clogged. Further, even if the aromatic substance 71 solidifies in the pores of the diffusion member 4 and causes clogging, the aromatic substance 71 is supplied to a room or the like through the elongated hole 41 having a large flow cross-sectional area.

Further, in the diffuser 1 according to the present embodiment, since the light of the incandescent lamp 5 leaks out through the pores and the elongated holes 41 of the diffusion member 4, the entire diffusion member 4 emits light, and the interior decoration is used at night. Also functions as a product.

Further, an air filter 37 is mounted on the air inlet portion, and a diffusion member 4 is mounted on the air outlet portion, and these members 37 and 4 are formed of porous members. The driving noise generated from the air supply pump 31 is attenuated by these members 37, 4, and these members 37, 4 also function as mufflers.

Further, since the diffusing member 4 is detachably attached to the upper protruding portion 22b, when a different kind of fragrance 71 is used, the diffusing member 4 is replaced with a new one and a different kind of fragrance 71 is used. Can be easily obtained.

Further, since the diffusion member 4 is formed of a porous member, the aromatic substance 71 impregnated in the diffusion member 4 is used.
Of the above, only the surface portion of the diffusion member 4 comes into contact with the surrounding air, and dust and bacteria floating in the surrounding air do not adhere to the entire fragrance 71, so that the deterioration of the fragrance 71 is suppressed. Is done.

In this embodiment, the liquid aromatic substance 7 is used.
1 is used to perform indoor aroma, but when a liquid deodorant is used instead of this aromatic substance, indoor deodorization can be performed, and a liquid insecticide can be applied to the diffusion member 4. When dripping, indoor insecticide can be performed, and when the diffusion member 4 is further impregnated with only water, it can be used as a humidifier. Furthermore, a rubber tube (not shown) may be connected to the outlet hole 61 of the cap 6, and the aromatic substance may be led to the bathroom of a sauna, a hot spring inn, or a bathroom for general households through the rubber tube. Furthermore, a plug 62 is inserted into the blowout hole 61 of the cap 6 in preparation for when the diffuser is not used, but the plug 62 is not always required. Furthermore, when an ultraviolet lamp (not shown) is installed in place of the incandescent lamp 5 installed in the diffusion member 4, bacteria that propagate in the diffusion member 4 may be killed by ultraviolet light emitted from the ultraviolet lamp. As a result, bacteria are not diffused into the room.
