When the navigation ECU 110 obtains that the road is congested by VICS or G-BOOK, the navigation ECU 110 transmits the information to the air quality component supply ECU 101. In response to this, the air quality component supply ECU 101 assumes that the occupant, in particular, the driver is sleepy, and uses the air quality component as the air quality component for the fragrance component, oxygen component, or cold air component that has been charged in the component storage unit 17 in advance. It is sent to the component chamber and contained in the air cannon and discharged toward the driver. As a result, the driver can eliminate drowsiness by inhaling these components from the nose, obtain an awakening effect, and can prevent a drowsy driving.

  Further, when the air quality component supply ECU 101 obtains traffic jam information from the navigation ECU 110, the air quality component supply ECU 101 assumes that the driver and other passengers are frustrated due to traffic jam and fills the component storage unit 17 in advance as an air quality component. Driver and other occupants are controlled by sending the fragrance, aroma, or ionic components from the component storage unit into the air quality component chamber and letting them into the air cannon and releasing them to the driver. Can make you feel relaxed.

  The vehicle integrated ECU 120 has a function of acquiring operation information of each functional component of the vehicle and communicating with the air quality component supply ECU 101. The operation information of each functional component includes, for example, vehicle speed information, brake information, inter-vehicle sensor information, window opening / closing information, and the like. The vehicle integrated ECU 120 transmits these pieces of information to the air quality component supply ECU 101. The air quality component supply ECU 101 recognizes information such as when the vehicle speed is equal to or lower than a predetermined value, the number of times of braking per unit time is equal to or higher than the predetermined value, or when the distance from the preceding vehicle by the inter-vehicle sensor is equal to or lower than the predetermined value. When it does, it is considered that there is a traffic jam, and as described above, it contains the aromatic component, oxygen component, or cold air component that has been filled in the component storage unit 17 in advance as an air quality component in order to supply the awakening effect In order to control the release of the air cannon to the driver or to provide a relaxing effect, the component storage unit 17 was previously filled with the aromatic component, aroma component, and ionic component as an air quality component. For example, the air gun is controlled to be released toward the driver.

  Further, when the vehicle integrated ECU 120 continuously obtains, for example, a value of 80 km or more as the vehicle speed information for a predetermined time or more, the air quality component supply ECU 101 assumes that the vehicle is traveling on a highway or the like and falls asleep. In order to prevent driving, the aroma component, oxygen component, or cold component, which has been filled in the component storage unit 17 in advance as an air quality component, is sent to the air quality component chamber in a predetermined amount, and is supplied to the air cannon. It is contained and released to the driver.

  Further, when the vehicle integrated ECU 120 transmits to the air quality component supply ECU 101 that the window is opened as the window opening / closing information, the air quality component supply ECU 101 recognizes that the outside wind is blowing into the vehicle, and is predetermined. Interlock control is performed to stop the release of the air cannon until information is obtained that the time or window is closed. When the window is open, the outside wind is flying in the car 2. Therefore, even if the air cannon is released, it is difficult to diffuse the air cannon toward a predetermined occupant or space. Is.

  The operation means 115 is for forcibly starting the vehicle air quality component supply device when the occupant himself wants to obtain a humidity component. For example, the occupant of the instrument panel 70 operates the occupant. It is configured in the form of a switch or button in an easy place. The operation means 115 activates the vehicle air quality component supply device 13, controls the magnitude of the compression force for compressing the air in the air quality component chamber 15, and releases an air cannon toward any space in the vehicle 2 or to any occupant. Means for instructing to control whether to

  Next, the internal configuration of the vehicle air quality supply device will be described. As shown in FIG. 3, the air quality component supply device for a vehicle has an air gun discharge port 27 on one end face in the housing 16A, and communicates with the discharge port 27 in the housing 16A. This is a configuration in which the chamber 15A and air compression means 14A for compressing and reducing the volume of the air quality component chamber 15A are provided on the other side.

  This air quality component chamber 15A is a space in which a predetermined air quality component generated in the component storage unit 17 passes through the opened valve 18 and is sent and stored by the transfer pump 19 via the connecting tube 20, and is transferred It is connected so as to communicate with the means 21. The air quality component transported by the transport means 21 is sent into the air quality component chamber 15A in a volatile state, and is filled in this volume. When the air quality component chamber 15A is filled with the air quality component more than necessary, the excess air quality component is discharged from the discharge port 27 to the outside. However, after the excess air quality component leaks, no further air quality component leaks immediately, and an appropriate amount of air quality component is retained in the air quality component chamber 15A.

  On the other hand, the air compression means 14A includes a compression member 40 that changes the volume of the air quality component chamber 15A by a magnetic force and an electromagnetic force, changes the volume of the air quality component chamber 15A, a magnet 41 provided in the compression member 40, and a compression The coil 42 is provided to face the member 40.

  When a voltage is applied to the air compressing means 14A from a vehicle-mounted battery or the like, an electromagnetic force is generated that causes a current to flow through the coil 42 and pushes the compression member 40 toward the air quality component chamber 15A. Further, a repulsive force is also exerted by the magnet 41, and a force for deforming the compression member 40 is exerted by the action of these electromagnetic force and magnetic force, so that the compression member 40 instantaneously acts on the air quality component chamber 15A side. Deforms greatly. At this time, the compression member 40 protrudes to the air quality component chamber 15A side up to a position 43 in a shape with its central portion protruding greatly, and the magnet 41 is also integrated with the compression member 40 to the air quality component chamber 15A side to the position 44. It will overhang. Due to the deformation of the compression member 40, the volume of the air quality component chamber 15A is instantaneously reduced, so that the air quality component filled in the volume is compressed and instantaneously discharged from the discharge port 27 to the outside. It will be. By causing this series of operations to occur instantaneously, air containing air quality components discharged from the discharge port 27 is discharged into the vehicle 2 as a fluid mass, for example, a vortex ring or a spherical mass.

  FIG. 4 is a perspective view showing the internal configuration of the housing 16A. The air quality component chamber 15A and the air compression means 14A are partitioned by a thin plate-shaped compression member 40. FIG. A coil 42 is arranged around the magnet 41 so as to surround it. The magnet 41 and the coil 42 are insulated by a resin member formed in a tubular shape. A cylindrical magnet 41 is arranged along the inner diameter of the resin member, and the magnet 41 slides on the inner diameter portion of the resin member along with the deformation of the compression member 40 due to electromagnetic force and magnetic force.

  The compression member 40 is composed of a plate-like member having a self-returning force, and is preferably composed of a thin plate such as rubber, silicon, or elastomer. By forming with these materials, the operating noise of the compression member can be reduced.

  The magnet 41 may be fixed to the compression member 40 by adhesion, or may be embedded in the compression member 40 and integrated. The coil 42 is arranged with a distance that does not contact the compression member 40 in a state where the compression member 40 is not deformed. The distance from the surface of the compression member 40 to the end surface of the housing 16A is as follows. It is desirable to configure the distance as small as possible to accommodate the magnet 41 as much as possible.

  As described above, in the configuration of the air compression means 14A, the magnet 41 is moved together with the compression member 40, so that a movable structure having excellent durability against repeated reciprocating motion can be obtained.

  By configuring the vehicle air quality component supply device in this manner, the size of the housing 16A can be made very small. For example, the length L1 in the longitudinal direction of the air quality component chamber 15A and the air compression means 15A is about 50 mm, the length Z1 in the length direction of the air quality chamber is about 30 mm, and the length X1 of the housing is about 30 mm. The diameter Y1 of the discharge port 27 can be formed to be about φ8 to 10 mm. Further, the shape of the housing 16A may be a cylindrical shape. In this case, the outer diameter dimension of the cylinder is about φ30 mm, and the inner diameter dimension of the discharge port is about 1/3 of the outer diameter dimension.

  The material of the housing 16A is not particularly limited, but is made of a material that can maintain a certain degree of airtightness such as resin and metal so that the humidity component filled in the air quality component chamber 15A does not leak.

  The component storage unit 17 includes a moisture supply unit and a heating unit that volatilizes the moisture supplied by the moisture supply unit, and may be provided in the air quality component supply chamber 15A. In this way, when the component storage unit 17 is configured integrally with the casing 16A, the component storage unit is separately provided as compared with the configuration in which the component storage unit 17 is connected to the casing 16 via the conveying means 21 as shown in FIG. There is no need to provide a casing for forming the apparatus 17, and the apparatus can be reduced in size. The water supply means may be constituted by a tube and water may be sent from the outside through the tube. The heating means is a heater that immediately heats the water flowing out from the tube, and can vaporize the water to make the air in the air quality component chamber high in humidity.

  The voltage applied to the air compression means 14 and 14A is a rectangular wave voltage as shown in FIG. 5 by ON / OFF control. By applying a rectangular wave voltage instead of a parabolic waveform voltage, an electric current is instantaneously passed through the coil 42, an electromagnetic force is generated in a short time, and the compression member 40 is deformed instantaneously. be able to. The rectangular wave is a voltage having a width of about 1 second, and this voltage is applied a plurality of times at intervals of about several seconds. By applying such a voltage application method, a plurality of air cannons are continuously released to the occupant, so even if there are some obstacles on the way, any one air cannon By hitting the occupant, the probability that the occupant senses a predetermined air quality component can be improved.

  The voltage to be applied may be a 12V voltage, for example, by being supplied from a vehicle-mounted battery. Further, in order to enhance the voltage applied to the air compression means 14 and 14A, a booster circuit using a capacitor may be used. For example, by boosting the applied voltage from 12V to 16V by a booster circuit, it is possible to increase the transport distance of the air cannon, and to provide a vehicle air quality supply device that expands the range of occupants who want to supply the air cannon. .

  Next, the structure in the case where the casing and the component storage unit are installed in a place separated from each other in the vehicle by the conveying means will be described.
