It is sectional drawing which shows the main part of the aroma mist generator which concerns on one Embodiment of this invention. It is a front view which shows the appearance of the aroma mist generator shown in FIG. It is explanatory drawing which shows the state which forms the donut-shaped aroma mist in the aroma mist generator shown in FIG. It is explanatory drawing which shows the state which forms the donut-shaped aroma mist when the upper surface of the outlet 4a is narrowed toward the center direction.

As shown in FIGS. 1 and 2, the aroma mist generator in the present embodiment includes a compressed air supply device 1 that supplies compressed air, a compressed air injection tube 2 for atomization, and a compressed air injection tube for donut mist. A housing 4 provided with a 3 is provided, and a bottle 5 containing aroma oil is attached to the lower end of the housing 4.

The compressed air supply device 1 includes a compressed air injection pipe 2 for atomization, a blower, a pump, and the like that supply compressed air to the compressed air injection pipe 3 for donut mist, and the compressed air injection pipe 2 for atomization and compression for donut mist. Compressed air suitable for each is supplied to the air injection pipe 3. Further, the compressed air supply device 1 supplies compressed air to at least the compressed air injection pipe 3 for donut mist by stopping the operation of the blower, the pump, or the like, or opening and closing the compressed air supply path by an actuator or the like. It is configured so that it can be switched between. Further, in this compressed air supply device 1, by driving and controlling a blower, a pump, etc., the compressed air to the compressed air injection pipe 3 for donut mist is supplied in a state of repeating supply and stop, or the compressed air is strong or weak. It is supplied with the.

The housing 4 has a tubular shape, and in the present embodiment, the housing 4 has a circular outlet 4a at the upper end, and a bottle 5 containing aroma oil is attached to the lower end. The bottle 5 is provided with an aroma oil pipe 6 that projects from the upper end thereof toward the inside of the housing 4. The tip 6b of the aroma oil pipe 6 is formed so as to be bent diagonally so as to have a slight angle with respect to the vertical, and the outlet 6a thereof faces diagonally upward. The compressed air injection pipe 2 for atomization is connected to the compressed air supply device 1, and its outlet 2a is arranged on the side of the outlet 6a of the aroma oil pipe 6 with respect to the outlet 6a of the aroma oil pipe 6. Compressed air is injected from the side so as to graze the surface of the outlet 6a. Further, the compressed air injection pipe 3 for donut mist is connected to the compressed air supply device 1, and the outlet 3a is arranged so as to be concentric with the center of the outlet 4a of the housing 4, and the outlet 3a is arranged. It is arranged so as to inject compressed air from the inside of the housing 4 toward the outlet 4a.

The housing 4 in the present embodiment is formed in a shape narrowed so that the diameter decreases from the lower end toward the upper end outlet 4a. Further, the compressed air injection pipe 3 for donut mist is arranged upward from substantially the center of the housing 4, and the compressed air injection pipe 2 for atomization and the aroma oil pipe 6 are forward in the direction in which the donut mist is blown out. If so, it is arranged behind the compressed air injection pipe 3 for donut mist (lower in the present embodiment).

Further, the compressed air injection pipe 2 for atomization and the compressed air injection pipe 3 for donut mist in the present embodiment are set to have diameters suitable for generating aroma mist and donut mist, respectively.

In the aroma mist generator having the above configuration, when compressed air is supplied from the compressed air supply device 1 to the atomizing compressed air injection pipe 2, as shown in FIG. 1, the atomization compressed air injection pipe 2 Compressed air adjusted to a flow velocity suitable for atomization is ejected from the outlet 2a of the atomizing compressed air injection pipe 2 so as to graze the surface of the outlet 6a of the aroma oil pipe 6. As a result, the pressure near the outlet 6a of the aroma oil pipe 6 becomes lower than the atmospheric pressure, and the aroma oil is sucked out from the aroma oil pipe 6 and blown out from the outlet 6a and blown off to become fine particles. Generates aroma mist 7. In FIG. 1, in order to clearly show the position of the generated aroma mist 7, the particles of the aroma mist 7 are exaggerated.

The aroma mist 7 is blown diagonally upward depending on the bending of the aroma oil pipe 6 and the injection direction of the compressed air from the atomizing compressed air injection pipe 2, and is arranged above the aroma oil pipe 6 for donut mist compression. The air flows between the air injection pipe 3 and the inner surface of the housing 4. Therefore, the aroma mist 7 does not collide with the compressed air injection pipe 3 for donut mist and return to the liquid, and the inside of the housing 4 is moved upward from between the compressed air injection pipe 3 for donut mist and the inner surface of the housing 4. Move towards. Then, the aroma mist 7 that has moved upward gathers at a high density in the vicinity of the outlet 4a because the housing 4 is narrowed down upward.

Here, when the compressed air supply device 1 supplies the compressed air for donut mist 3 with a momentary and high-speed compressed air, the compressed air is discharged from the outlet 3a of the compressed air injection pipe 3 for donut mist to the housing 4. Is ejected toward the outlet 4a of the air. As described above, when the compressed air of the compressed air injection tube 3 for donut mist is instantaneously and high-speed compressed air is ejected from the outlet 3a, as shown in FIG. 3, the air 8 near the center of the outlet 3a has a high flow velocity. The air flows substantially straight in the axial direction, and the air 9 located radially outside from the center of the outlet 3a flows so as to spread outward in the radial direction while reducing the flow velocity. The flow of the air 9 is pushed up in that state by the flow of the air 10 going upward while spreading, and spreads in the radial direction, descends, and then rises again on the flow of the air 10 in a circular shape like the air 11. Form a flow. The aroma mist 7 near the outlet 4a of the housing 4 is involved in the flow of the air 11, and a donut-shaped donut mist 12 is generated. The donut mist 12 rises while spreading in the radial direction, and when the flow of the air 11 is weakened, the donut-shaped body is broken and diffused. As shown in FIG. 4, the upper surface of the outlet 4a of the housing 4 may be formed into a shape narrowed toward the center of the outlet 4a. By forming in this way, it becomes easier to form a circular flow.

As described above, in the aroma mist 7 and the donut mist 12, the atomizing compressed air injection tube 2 and the donut mist compressed air injection tube 3 are formed in diameters suitable for producing the aroma mist 7 and the donut mist 12, respectively. If so, it can be generated only by supplying compressed air from the compressed air supply device 1. Further, the compressed air supplied from the compressed air supply device 1 is compressed by the compressed air injection pipe 2 for atomization and the compressed air injection pipe 3 for donut mist at the same time or individually with intermittent or strong or weakening or continuously. By supplying air, aroma mist 7 and donut mist 12 can be generated.

Further, since the generated donut mist 12 contains the aroma mist 7 in a donut shape, the aroma mist 7 is confined in the donut shape. Therefore, by blowing the donut mist 12 toward a specific place in the state of the donut mist 12, the aroma mist 7 can be delivered to a specific place in a concentrated manner.

Further, by stopping the supply of compressed air to the compressed air injection pipe 3 for donut mist or supplying low-speed compressed air in which the donut mist 12 is not generated, a mist-like aroma mist is supplied from the outlet 4a of the housing 4. It is also possible to blow out 7 as it is.
