  When supplying the fragrance component to the air cannon 11, any of the fragrance containers 22 a to 22 c and the chamber 23 are switched to the communication state by switching control of the electromagnetic valve 24. By driving the pumping pump 25 in this state, the air taken in from the air intake 26 flows into the chamber 23 together with the fragrance component via the fragrance containers 22a to 22c, and the barrel of the air cannon 11 from the chamber 23 It will be supplied to the part 11c. Note that check valves 27a to 27c are provided between the fragrance containers 22a to 22c and the air intake port 26, and leakage of fragrance components is prevented by the check valves 27a to 27c.

Furthermore, ozone (O ₃ ) as an active ingredient is supplied to the main unit 14 in order to deodorize the fragrance supply unit 19 when switching the fragrance component, or to deodorize the fragrance component remaining in the room. An ozone supply unit (ozone supply means) 30 is incorporated. As shown in FIG. 4, the ozone supply unit 30 includes a discharge unit 31 including a needle-like discharge electrode 31 a and an annular counter electrode 31 b, and a blower fan 32 that supplies air to the discharge unit 31. Yes. When generating ozone using such an ozone supply unit 30, a high voltage is applied to the discharge unit 31 while driving the blower fan 32 to supply air to the discharge unit 31. Thereby, it is possible to generate a silent discharge near the tip of the discharge electrode 31a to generate ozone. In addition, as shown in FIG. 2, a first supply path 33 and a second supply path 34 are connected to the ozone supply unit 30, and ozone is supplied from the ozone supply unit 30 to the selected supply paths 33 and 34. Can be supplied. Since the first supply path 33 is connected to the fragrance supply unit 19, ozone can be supplied to the fragrance supply unit 19 through the first supply path 33. Further, since the second supply path 34 is connected to the discharge port 35 of the main unit 14, it is possible to release ozone from the discharge port 35 through the second supply path 34.

  The control unit 36 that outputs a control signal to the drive circuit unit 15, the fragrance supply unit 19, the ozone supply unit 30 and the like includes a microprocessor (CPU) (not shown), and this CPU has a ROM via a bus line. RAM and I / O ports are connected. The ROM stores control programs, various map data, and the like, and the RAM temporarily stores data processed by the CPU. The main unit 14 is provided with a switch 37 operated by the operator W. The switch 37 is a switch that is operated when the supply device 10 is activated or the fragrance component is switched. An on / off signal and a fragrance selection signal are output from the switch 37 in accordance with the switch operation of the operator W, and the supply device 10 is switched between an activated state and a stopped state according to the on / off signal, and the air cannon 11 is filled according to the fragrance selection signal. A fragrance component is selected.

  Further, the main unit 14 incorporates a work state detection unit 40 as an awakening detection means for detecting the awakening level (attention) of the worker W. Here, FIG. 5 is a block diagram showing a configuration of the work state detection unit 40. As illustrated in FIG. 5, the work state detection unit 40 includes a camera 41 that detects the gaze behavior (eye movement) of the worker W, and a wakefulness determination unit 42 that processes an image signal from the camera 41. . The work state detection unit 40 includes a heart rate sensor 43 that measures the heart rate of the worker W and a body motion sensor 44 that detects the movement of the worker W's body. As shown in FIG. 1, the heart rate sensor 43 and the body motion sensor 44 are attached to a chair 45 on which the worker W sits, and can detect the heart rate and movement of the worker W. As shown in FIG. 5, the arousal level determination unit 42 comprehensively calculates the arousal level of the worker W based on the image signal from the camera 41, the heart rate signal from the heart rate sensor 43, and the body motion signal from the body motion sensor 44. Judgment. The arousal level determined by the awakening level determination unit 42 is output to the control unit 36, and when the arousal level falls below a predetermined level, an aroma component having an awakening effect is selected.

  In the above description, the awakening level determination unit 42 is incorporated into the main unit 14, but the present invention is not limited to this, and the awakening level determination unit 42 may be incorporated in an external device. For example, in an environment where the worker W works using a personal computer, the awakening degree determination program may be operated by background processing of the personal computer by connecting the personal computer and the supply device 10. good. In this case, the system is configured such that the arousal level information determined by the personal computer is transmitted to the supply device 10. Further, in an environment where the operator W operates a computer terminal or the like, it is possible to determine the arousal level based on the operation tendency and the operation frequency.

  Next, aroma component switching control executed by the control unit 36 will be described. When the operator W switches the fragrance component, the electromagnetic valve 24 is switched based on the fragrance selection signal from the switch 37 in order to supply the fragrance component selected by the worker W to the air gun 11. The pressure feed pump 25 is driven. In addition, when the arousal level determination unit 42 determines that the awakening level of the worker W is below a predetermined level, a mint-based or citrus-based aroma component having an awakening effect is supplied to the air cannon 11. Thus, the electromagnetic valve 24 is switched, and the pressure pump 25 is driven.

  Here, if a new fragrance component is simply supplied to the air cannon 11, the two fragrance components are mixed in the chamber 23 and each supply path, which may cause discomfort to the operator W. There is a possibility that a sufficient awakening effect may not be given to the worker W. Therefore, the control unit 36 supplies ozone from the ozone supply unit 30 to the downstream side of the electromagnetic valve 24 before switching the electromagnetic valve 24 to introduce a new fragrance component. By supplying ozone in this way, the fragrance component before switching remaining in the chamber 23 and the supply path can be deodorized by ozone, and a new fragrance component is added to the worker W without mixing the fragrance component. Can be supplied. Thereby, even if it is a case where a several fragrance component is switched and discharge | released, it becomes possible to supply a new fragrance component, without giving the worker W discomfort. In addition, even when switching to the fragrance component in order to evoke the attention of the worker W, a sufficient awakening effect can be given to the worker W.

  Subsequently, the aroma component switching control described above will be described with reference to a flowchart. Here, FIG. 6 is a flowchart showing an execution procedure of the fragrance component switching control. As shown in FIG. 6, in step S <b> 1, an aroma component is selected based on the switch operation of the worker W and the awakening level of the worker W. In subsequent step S2, a control signal is output from the control unit 36 to the fragrance supply unit 19, and the barrel portion 11c of the air gun 11 is filled with the fragrance component selected in step S1. Next, the process proceeds to step S 3, and the vortex rings V 1 and V 2 are fired from the respective air cannons 11 and 12 by outputting a firing signal from the control unit 36 to the drive circuit unit 15. Is supplied.

  Subsequently, in step S4, it is determined whether or not the vortex rings V1 and V2 are continuously fired based on the switch operation of the worker W and the awakening level of the worker W. If it is determined in step S4 that the vortex rings V1 and V2 are not to be continuously fired, the routine is directly exited. On the other hand, if it is determined in step S4 that the vortex rings V1 and V2 are to be continuously fired, It progresses to S5 and it is determined whether a fragrance component is switched.

  If it is determined in step S5 that the fragrance component is not to be switched, deodorization in the fragrance supply unit 19 is not necessary, and thus the emission control of the air cannon 11 is continued from step S2. On the other hand, if it is determined in step S5 that the fragrance component is to be switched, the process proceeds to step S6 to deodorize the fragrance supply unit 19 before introducing a new fragrance component. On the other hand, ozone is supplied. When the deodorization in the fragrance supply unit 19 is completed, ozone is discharged from the fragrance supply unit 19 in the subsequent step S7, and the emission control of the air cannon 11 using a new fragrance component is started again from step S2. It will be. As described above, when the fragrance component is switched and output, the fragrance supply unit 19 is deodorized using ozone, so that a new fragrance component is supplied without causing the worker W to feel uncomfortable. It becomes possible. If it is determined in step S4 that the vortex rings V1 and V2 are not to be continuously fired, the routine is directly exited, but the fragrance is prepared in case the launch control of the vortex rings V1 and V2 is resumed. Ozone may be supplied into the supply unit 19 to deodorize the fragrance supply unit 19.

  As described above, by supplying ozone from the ozone supply unit 30 to the fragrance supply unit 19, it is possible to switch the fragrance component without causing the worker W to feel uncomfortable. The supply destination of such ozone is not limited to the fragrance supply unit 19, and ozone is supplied from the ozone supply unit 30 to the discharge port 35 through the second supply path 34 as shown in FIG. 2. Is also possible. Thus, by releasing ozone from the discharge port 35 into a room such as a work room in which the supply device 10 is installed, it is possible to deodorize and sterilize the room and maintain a good indoor environment. In addition, ozone emission from the discharge port 35 to the room is executed according to a switch operation, a control program, or the like.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above description, the supply device 10 is installed in the office. However, the supply device 10 is not limited to this, and can be installed in various environments where a refreshing effect or a relaxing effect by an aromatic component is desired. is there. For example, the supply device 10 may be installed in a waiting room, a conference room, a movie theater, a control room, a classroom, a home, or the like. It is also possible to install the supply device 10 in a cabin such as an aircraft or a ship. Furthermore, in the illustrated case, the supply device 10 is installed on the desk 13, but the present invention is not limited to this position, and it goes without saying that the supply device 10 may be installed on a wall, ceiling, or the like. Nor.

  In addition, the illustrated supply device 10 is a stereo-type supply device in which the pair of air cannons 11 and 12 are provided so that the vortex rings V1 and V2 collide with each other, but this is not a limitation. The present invention can be effectively applied even to a supply device including one air cannon. In the illustrated case, the air cannons 11 and 12 are fixed. However, the air cannons 11 and 12 may be rotated using an electric motor or the like. In this way, by making the air cannons 11 and 12 turnable, the efficacy area A can be set widely. Further, in the illustrated case, the fragrance component is supplied to one of the air cannons 11, but the fragrance component may be supplied to both of the air cannons 11 and 12.

  In the illustrated case, the electric motor is driven to project the rod members 11d and 12d so that the vortex rings V1 and V2 are fired from the air cannons 11 and 12. However, the structure is limited to this. Instead, by incorporating an electromagnetic coil and a movable iron core into the air cannons 11 and 12, the vortex rings V1 and V2 may be fired from the air cannons 11 and 12 using electromagnetic force. Furthermore, although the air cannons 11 and 12 include bellows-shaped pump bodies 11a and 12a, air may be pushed out using a diaphragm. Furthermore, although the annular vortex rings V1 and V2 are fired from the air cannons 11 and 12, the shape of the first air vortex and the second air vortex is not limited to the annular shape, and is a predetermined shape with a set shape. An air vortex of any shape may be used as long as the distance can be skipped.

  Further, in order to generate ozone by the ozone supply unit 30, air is supplied to the discharge unit 31, but oxygen may be supplied to the discharge unit 31, and the discharge unit 31 may be dried. You may make it supply the made air. In the above description, the fragrance component is generated from the main unit 14, but in addition to the fragrance component, the micro mist (humidity component, minute moisture floating in the air) that gives the worker W moisture and refreshment. Particles) may be generated, or oxygen having an awakening effect on the worker W may be generated.
