Description

Vehicle fragrance equipment

The present invention relates to a fragrance device used in a boarding / boarding space in a vehicle such as an automobile, an aircraft, or a ship. In particular, the present invention relates to a vehicle fragrance device for spreading a scent in a boarding / boarding space using a plant-derived fragrance component such as essential oil.

Conventionally, air fresheners and deodorants have been used in various facilities such as hotels, beauty salons, stores, homes, and various spaces such as living rooms, toilets, and other entrances. Furthermore, deodorizers and fragrances are also used in automobiles in order to deodorize or scent the interior space. The usage rate of deodorant and fragrance in a vehicle such as an automobile is considered to be lower than the usage rate of deodorant and fragrance in a building such as a residence. However, since the penetration rate of automobiles is high and important as an item for creating a more comfortable space, the demand for deodorants and fragrances for vehicles (particularly automobiles) is high.

Therefore, various deodorizing and fragrance agents for vehicles (particularly automobiles) have been provided in the past, and are disclosed, for example, in the following patent documents.

Patent Document 1 (Japanese Utility Model Publication No. 07-009612) proposes an automobile aroma device that is attached to the air outlet of an air conditioner in a vehicle and emits a certain aroma as needed. That is, in this patent document 1, an automobile aroma device in which a cylindrical shutter provided with two or more holes is provided at the bottom of a box provided with a clip on the back surface, and a fragrance storage portion is provided inside the shutter. is suggesting.

Further, Patent Document 2 (Japanese Patent Laid-Open No. 2001-037859) proposes a fragrance sprayer that is disposed in a vehicle compartment or the like and sprays fragrance by operating a switch. In this patent document 2, a fragrance spreader in which a wick for releasing fragrance is housed in a main body case, a switch is operated to open a slat and rotate a fan so that the fragrance is discharged from a blowout port of the main body case. A fragrance sprayer that is sprayed outside is proposed.

However, since it may stay in the car for a long time, the synthetic fragrance may cause discomfort. On the other hand, in the past, in order to create a more comfortable space, it is also used to scent the space using essential oils. And it is known that essential oil is a plant-derived natural component and has a low possibility of causing discomfort even if it is smelled for a long time.

Japanese Patent Application Laid-Open No. 05-220207 proposes a fragrance using such a plant-derived natural fragrance. In this patent document 3, a simple and economical device for reducing the odor inside an automobile is proposed, and the use of essential oil (essential oil) is also proposed. That is, it consists of a main body made of a polymer material containing a substance that acts against odor, which is linked to a cigarette lighter attached to a dashboard of an automobile, and heating of the cigarette lighter is activated from the heated main body of polymer material. We have proposed a device for reducing odor inside automobiles that releases substances temporarily.

Japanese Utility Model Publication No. 07-009612 JP 2001-037859 A JP 05-220207 A

As described above, there have been proposals for a car fragrance that attaches to the air outlet of an air conditioner or the like and emits a certain fragrance, or an odor reducing device inside the car using essential oil. However, in Patent Document 1 and Patent Document 2, a fan is used to emit a scent. When the fan is driven and the scent is diffused, a driving sound of the fan may be generated, and heat is also expected to be generated when the motor driving the fan is operated. If an unpleasant sound such as a driving sound or heat is generated by driving the fan, there is a possibility that the production of a comfortable interior space is hindered.

Also, in Patent Document 3, there is a problem that the cigar socket is occupied because of the mechanism for releasing the scent by using the heat of the cigarette lighter. That is, since the cigar socket in a vehicle is used for various purposes such as charging a mobile phone or using a portable navigation, an fragrance device that can be used without using the cigar socket has been desired.

Therefore, a first object of the present invention is to provide a vehicle fragrance device that can be used without generating unpleasant sounds such as motor and fan drive sounds and without using a cigar socket in a vehicle.

Also, some fragrance appliances release a fragrance by moistening a built-in film or filter with a fragrance and volatilizing the fragrance when used. However, with these fragrance devices, each time of use, it was necessary to hang the fragrance or to turn the device upside down, so it was desired to simplify the operation at the time of use. . In addition, this type of fragrance device has a problem that it is not economical because a large amount of oil is consumed because the entire built-in film or filter needs to be moistened with the fragrance component.

Therefore, in the present invention, a second object is to provide a vehicle fragrance device that is easy to use even when used, and further, the amount of fragrance used can be optimized and used at a low cost. Providing a device is a third problem.

Furthermore, as a simpler method, a method of scenting a fragrance with a tissue and volatilizing the fragrance can be considered. However, when soaking a fragrance oil in a tissue or the like, it is difficult to adjust the amount of oil to be soaked, and there is a possibility of spilling, so that the oil may be wasted. When the oil used for the fragrance is a plant-derived oil, it is expensive, and there is a problem that the purchase cost of the oil increases. In addition, since oils that perfume may contain components that dissolve plastics, if spilled, there is a risk of contaminating (invading) the in-vehicle device, so that the oil does not spill as much as possible. There was a need to design. In particular, when used in an automobile, shaking occurs during movement, and since it is a sealed space, the temperature difference is so severe that the fragrance component tends to spill. In addition, it is not possible to deny the possibility of spilling oil into the vehicle when using a plant-derived oil and refilling it with a fragrance device that uses a cigar socket in the vehicle as in Patent Document 3, etc. Problems such as contamination and damage will occur.

Therefore, in the present invention, it is a fourth object to provide a vehicle fragrance device that can use an appropriate amount of oil for aroma, is economical, and does not accidentally spill even when used in a vehicle. It is an issue.

In order to solve at least one of the above-mentioned problems, in the present invention, a fragrance component can be diffused by a natural vaporization method, easily swaying during movement, and even in a vehicle where the difference between high temperature and low temperature is significant, The present invention provides a vehicle fragrance device that employs a structure in which a fragrance component in a container does not spill out.

That is, in the present invention, a vehicle fragrance device installed in a vehicle, a container body having an opening at the upper end, a liquid fragrance component filled in the internal space of the container body, and the container body Inserted from the opening, the lower end side is present in the fragrance component in the container body, and the upper end surface is composed of a long suction member exposed from the opening, and in the internal space of the container body In the region where there is no fragrance component, an exhaust port communicating with the external space of the container body is opened, and the exhaust port allows the gas in the container body to flow according to the viscosity or flowability of the fragrance component. Provided is a vehicle fragrance device that is formed in a size and shape that prevents leakage of a liquid fragrance component filled in the container body while being discharged.

The exhaust port can be formed by a single vertical hole or vertical groove extending in the length direction (desirably penetrating) formed in the suction member. Therefore, in the present invention, there is a vehicle fragrance device installed in a vehicle, which contains a liquid fragrance component and has an opening at its upper end, and is inserted through the opening in the container body. The lower end side is present in the aromatic component in the container body, and the upper end surface is provided with a long suction member exposed from the opening, and the suction member extends in the length direction. Provided is a vehicle fragrance device in which only one longitudinal hole or longitudinal groove (preferably penetrating) is formed.

The aromatic component is not particularly limited, but is a volatile oil (liquid component) derived from natural plants such as rose, jasmine, chamomile, lavender, lemongrass, rosemary, essential oil, aroma oil, etc. You can use what is provided as. As a fragrance component according to the present invention, by using a fragrance component derived from a natural plant as described above, even when staying in the vehicle for a long time, the situation where the fragrance is too strong and offends. Furthermore, it is possible to enjoy an action derived from the scent of an aromatic component derived from a natural plant, for example, an action of calming brain activity and autonomic nerves and creating a relaxing state. That is, by using a natural plant-derived fragrance component, it is possible to alleviate the driver's stress and frustration during long-distance driving or traffic jams, and to use it for safer driving. Therefore, it is desirable that the fragrance component according to the present invention is manufactured from 100% plant-derived materials without adding synthetic substances or adjusting components as much as possible.

And the said fragrance component is accommodated in the container main body which has an opening part in an upper end. Such a container main body may be formed of a material that does not allow liquid aroma components to permeate, but is preferably selected appropriately according to the aroma components. For example, when a plant-derived essential oil is used as an aromatic component, it is desirable to use a light-shielding container in order to prevent a change in quality. This is because, when a plant-derived liquid fragrance component is accommodated as the fragrance component, it is necessary to be formed of a material and a color that block the penetration of light in order to avoid alteration of the fragrance component. In other words, the plant-derived liquid aroma component does not contain extra synthetic substances, and is less susceptible to external influences in sunlight and the like than synthetic fragrances (artificial fragrances), and is therefore susceptible to alteration and the like. By using the container, quality change can be prevented. As a material for forming the light shielding container, glass, ceramics, metal, resin, or the like can be used. In particular, a light-shielding bottle formed using glass is excellent in design effect. In addition, some plant-derived liquid aroma components dissolve or alter the resin, so that the surface that has light-shielding properties and contacts the aroma component is altered by the contained aroma component. It is desirable to use a material that does not cause such as. Therefore, when plant-derived essential oil is used as the fragrance component, it is desirable to use glass, earthenware, or a metal shading bottle for the container body. *

A liquid fragrance component is accommodated in the internal space in the container body, and an exhaust port communicating with the external space of the container body is opened in an area where the fragrance component does not exist in the internal space. The exhaust port functions as an exhaust port for escaping air in the internal space expanded in a high temperature environment and preventing an increase in atmospheric pressure. That is, when the temperature in the container body suddenly increases due to a vehicle heater or the like, the air in the container body expands to increase the internal pressure. In this state, if there is no exhaust port, the aroma component is pushed up to the upper end surface of the suction member in a large amount due to the increased pressure in the container body. The fragrance component that has reached the upper end surface of the wicking member (the fragrance component exceeding the amount of natural vaporization) does not slip back into the container body, and spills down as it travels along the outer surface of the container. As a result, not only is the fragrance component consumed unnecessarily, but depending on the type of spilled fragrance component, the resin parts in the vehicle may be altered or dissolved. However, as in the vehicle fragrance device according to the present invention, by forming the exhaust port, the gas in the raised container body can be quickly discharged, and the interior of the container body can be returned to normal pressure. As a result, a vehicle fragrance device has been realized that eliminates a situation in which the fragrance component spills out even in a vehicle where the difference between the temperature and the temperature is severe, and prevents waste of the fragrance component and alteration of resin parts in the vehicle.

Although the exhaust port can be formed as a through hole in the container body, it is desirable to form it on a suction member or a holding member that holds the suction member in the opening as will be described later. However, the exhaust port needs to be formed in a size and shape that prevents leakage of the liquid aroma component filled in the container body while discharging the gas in the container body. For this purpose, the exhaust port is preferably formed to have a length of about 4 mm or more in consideration of the surface tension of the fragrance component. By setting the length of the exhaust port to 4 mm or more, the surface tension of the fragrance component acts to prevent leakage of the fragrance component.

Also, an elongate wicking member is provided at the opening of the container body to suck up the fragrance component contained in the container and diffuse the fragrance into the space. The suction member is inserted into the opening of the container body, and is preferably installed in a state of being fitted inside the opening. This is to eliminate the situation where the suction member falls off when used in a swaying vehicle. However, it does not exclude that the suction member is slidable in the length direction with respect to the opening. By changing the amount of protrusion from the opening by moving the sucking member up and down, the exposed area to the space where the scent is diffused changes, and the volatilization amount of the fragrance component can be adjusted accordingly. This is to respond to various needs.

In particular, when the suction member is provided to be slidable in the length direction with respect to the opening, the lower side of the suction member is immersed and immersed in the aroma component in the container body. The fragrance component can be sucked up. And the volatilization amount of a fragrance | flavor component can be adjusted by adjusting the surface area exposed from an opening part, and the depth to immerse. This is an advantageous effect in vehicles, especially in automobiles. This is because the inside and outside of a car is very crowded and the fragrance component is released to the outside of the vehicle and the fragrance may be weakened. This is because the scent strength in a narrow interior space may not be stable. In this respect, by forming the suction member so as to be slidable in the length direction, the exposed area of the suction member can be changed, and the volatilization amount (or diffusion amount) of the fragrance component can be arbitrarily adjusted.

In addition, the wicking member has a buffer on the lower side for sucking up the liquid fragrance component so that the fragrance component in the container body can be surely sucked up even when the fragrance component is low. It is desirable to provide a member. The buffer member is preferably formed of a material having elasticity or flexibility, and can be formed into a lump or string using, for example, foamed resin such as cotton, nonwoven fabric, or sponge. In particular, when the sucking member is slidably provided, the lower end side is in contact with the bottom surface in the container body and the sucking member is slid upward even when the sucking member is slid upward. It can be formed in a length and shape in contact with the bottom surface of the member, and as a result, the fragrance component can be continuously supplied to the sucking member that has been slid upward.

The sucking member functions as a member that sucks up the aromatic component in the container main body by permeation or capillary action. Such a sucking member is often formed in a rod shape, but can be formed in various long shapes such as a long plate shape and a linear shape. Further, it is desirable to form a vertical hole or a vertical groove extending (preferably penetrating) in the longitudinal direction in the suction member. This is because, if such a vertical hole or groove is formed, it can be used as an exhaust port for exhausting the gas in the internal space when the pressure in the internal space of the container body rises due to the environmental temperature. Further, by forming the vertical hole or the vertical groove, the aromatic component can be sucked up by capillary action. The fragrance component sucked into the vertical hole or groove can penetrate the suction member and spread over the entire suction member. As a result, the fragrance component is naturally removed from the entire exposed surface of the suction member. It can be vaporized.

Only one vertical hole or vertical groove is formed. Because, when two or more vertical holes or vertical grooves are provided, the aromatic component can be sucked up by capillary action, but when the container is accidentally turned over, a plurality of vertical holes or vertical grooves This is because air enters the container from the inside, the pressure inside and outside the container becomes equal, and the aromatic components in the container spill out. On the other hand, when only one vertical hole or vertical groove is formed, even if the container is accidentally overturned or is used in a vehicle where vibration or shaking occurs, the liquid fragrance component is present. The risk of spilling out can be reduced as much as possible. Further, the shape of the vertical hole or the vertical groove is preferably formed linearly, but may be formed in a spiral shape, a saw blade shape, or a wave shape. That is, it is sufficient that only one vertical hole or vertical groove is formed in the suction member, and the shape thereof may be arbitrarily selected.

In consideration of the suction efficiency of the fragrance component, it is desirable that the cross-sectional area of the vertical hole or groove is 4 mm ² or less, particularly 2 mm ² or less. This is because when the cross-sectional area of the vertical hole or vertical groove exceeds 4 mm ² , it becomes difficult to suck up by the capillary phenomenon, or a large amount of the aromatic component is sucked up, and the aromatic component is consumed wastefully. This is because there is a possibility that the aromatic component may be spilled out when the container is accidentally turned over. In the case where a vertical hole or a vertical groove having a cross-sectional area of 4 mm ² or less is formed, the suction member may be formed of a material having no permeation power such as metal or glass or an extremely low material. However, in order to improve the diffusibility with respect to space, it is desirable to have a certain osmotic force, and therefore, it is desirable to form with felt, permeable resin, wood, bamboo, cork or the like. However, if a material with high penetrating power such as felt is used, a large amount of fragrance components are sucked up, the amount of volatilization is large, and fragrance components are consumed wastefully. It can be thought that it will become bulky. Therefore, the material of the suction member according to the present invention is excellent in diffusibility and wastefully aroma components depending on the size of the interior space to be used and the use of the vehicle (whether the vehicle gets on and off frequently). It is desirable to be made of materials that do not consume energy, such as wood, bamboo, or cork, especially wood or bamboo.

The vertical hole or groove formed in the suction member not only discharges the gas in the internal space expanded under high temperature, but also removes the fragrance component that has oozed out from the upper end surface of the suction member under high temperature environment. Can function to return inside. That is, after the inside of the container body returns to normal pressure by exhausting from the longitudinal hole or longitudinal groove (exhaust port), the longitudinal hole or longitudinal groove functions to return excess fragrance components into the container body. I can do it. Therefore, the vertical hole or the vertical groove can function as a passage (bottleway) for discharging the expanded gas and returning the fragrance component to the internal space, and the excess fragrance component can be removed through the vertical hole or the vertical groove. Can be returned to the container.

In the vehicle fragrance device according to the present invention, it is desirable to provide a circumferential groove communicating with the vertical hole or the vertical groove around the suction member. This is because the fragrance component that has exuded on the upper end surface of the suction member is received and smoothly guided to the vertical hole or the vertical groove. In addition, a fragrance component is present in the vertical hole or groove due to capillarity, and when the internal pressure of the container body increases due to a temperature rise, the fragrance component present in the vertical hole or groove is It may be pushed out by the gas discharged from the body. Therefore, the circumferential groove is formed as a groove for receiving the extruded aroma component. By forming the circumferential groove, the fragrance component pushed out by the internal pressure is once held in the circumferential groove, and when the gas in the container body is sufficiently discharged and returned to normal pressure, The aromatic component in the groove can return to the container body through the vertical hole or the vertical groove. Therefore, by forming the circumferential groove, even if a large amount of fragrance component is leached due to a sudden temperature change, even if the fragrance component is present in the vertical hole or the vertical groove due to capillary action, etc., it is accepted. Thus, it is possible to avoid a situation where the container body spills.

The circumferential groove is a groove formed so as to go around the side surface (preferably the upper end side) of the suction member, and is formed to communicate with at least the vertical hole or the vertical groove. It is desirable that the upper end opening of the groove is adjacent to the upper end surface of the suction member so that the circular groove can also receive the fragrance component that has oozed out from the upper end surface of the suction member. Such a circumferential groove can be formed in the suction member by notching the upper end side of the suction member provided in the opening of the container body and reducing the diameter. In addition, when the suction member is provided in the opening of the container body using a holding member described later, this holding member is formed by expanding the upper end side of the opening provided in the suction member. Circumferential grooves can be formed. Further, the upper end side of the suction member can be reduced in diameter, and the upper end side of the opening in the holding member can be increased in diameter.

Further, the peripheral groove can be formed such that the space volume in the groove is equal to or larger than the space volume of the vertical hole or the vertical groove. This is for securing a volume capable of accommodating all the aromatic components present in the vertical holes or the vertical grooves.

Furthermore, this circumferential groove may be formed to a depth greater than the groove width. Depending on the installation location of the vehicle, the vehicle fragrance device may be installed in an inclined state, and even in such a case, the fragrance component is prevented from spilling from the circulation groove. Furthermore, by making the groove width as narrow as possible, it is possible to secure a wider area of the upper end surface for natural vaporization of the fragrance component, and to enhance the design effect by forming the circumferential groove so as not to stand out. Can do.

In order to hold the sucking member in the opening of the container body, it is desirable to provide a holding member for holding the sucking member between them. The holding member is formed between the suction member and the opening of the container main body so as to hold the liquid-tight space therebetween. For example, when the opening of the container body is formed in a cylindrical shape and the suction member is formed in a columnar shape having a groove formed on the outer peripheral surface, the holding member can be formed in a cylindrical shape. .

¡This holding member can also be formed with an exhaust port for discharging the gas in the internal space of the container body that has expanded due to a rapid temperature change. Such an exhaust port can be formed as a vertical hole or a vertical groove penetrating in the height direction (axial direction) of the holding member. In particular, when the inner peripheral surface is formed as a vertical groove, the exhaust port can be partitioned from the outer peripheral surface of the suction member.

Further, when the sucking member is slidably provided in the opening, the holding member can be formed with various members and structures as long as the function and function are ensured. Furthermore, the holding member is formed with an outer diameter smaller than the inner diameter of the opening so as not to be wrinkled, deformed, or distorted when inserted into the opening of the light shielding container. It can also be formed so as to expand by absorbing the aromatic component inside and to adhere to the opening of the light shielding container. When the holding member is formed so as to absorb a fragrance component and expand, it can be formed of a resin material such as paper, cork, rubber, urethane or elastomer as a material for forming the holding member, particularly silicon. It is desirable to form using. When formed using silicon, the holding member can be expanded by using a fragrance component other than the fragrance component derived from flowers. At this time, when it is desired to form the inner diameter of the opening of the container body to about 14 mm, the silicon holding member can be formed to have an outer diameter of about 12 mm. The holding member absorbs the fragrance component through the sucking member and expands, so that when installed in the opening of the container body, it can be installed smoothly without unintended deformation or wrinkling. It becomes possible to do.

Also, as described above, the holding member that expands by absorbing the fragrance component expands not only in the radial direction but also in the length direction. Therefore, if the axial length of the holding member is formed to be approximately the same as the axial length of the opening, when expanded, the holding member expands into the accommodation space of the fragrance component that is spread on the base side of the opening, and the fragrance It catches on the upper end of the component storage space. As a result, the holding member becomes difficult to be pulled out, and even if the suction member is slid, the holding member does not come out of the opening.

On the other hand, when a flower-derived essential oil is used as an aromatic component, even if the holding member is made of silicon, it does not expand or the amount of expansion is slight. Therefore, when using the essential oil derived from a flower as an aromatic component, the holding member needs to be formed in a size that fits into the opening of the light shielding container. That is, the vehicle fragrance device according to the present invention adjusts the size of the holding member with respect to the opening of the light shielding container according to the fragrance component to be used (that is, whether or not it is derived from a flower), or is fitted or You can choose whether to loose fit.

Furthermore, it is desirable to form the holding member so as to always maintain a constant size regardless of the aromatic component used. This is because the range of essential oils that can be used can be expanded, and a common holding member can be used in various essential oils, thereby reducing the manufacturing cost and the number of parts. Regardless of the type of essential oil, the holding member that can always maintain a constant size can be manufactured by using, for example, fluororubber.

Then, the container body, which includes the suction member and the holding member as described above and is filled with the fragrance component, is installed at the air outlet in the vehicle by a fixture or the like that holds the container body. More specifically, the vehicle fragrance device is installed so that the sucking member comes into contact with the air ejected from the air outlet in the vehicle. Therefore, the fixture is configured to hold the container body and be installed at the air outlet in the vehicle. For example, a clip, an arm, etc. can be provided so that the container body can be installed at the air outlet. In the container main body held by the fixture, liquid aroma components such as plants are contained, and this is sucked up by the sucking member and exposed to the air emitted from the air outlet, The fragrance of the fragrance component can be spread in the vehicle space.

In addition, the vehicle fragrance device according to the present invention includes the suction member and the holding member, so that the fragrance component is not consumed unnecessarily, and spillage of the fragrance component that is economical and inadvertent is suppressed. be able to.

The vehicle fragrance device according to the present invention can be used not only for automobiles but also for ships, airplanes, and the like in order to smell or deodorize boarding spaces and luggage storage spaces. However, when plant-derived oil is used as the fragrance component, it is preferably installed in the air outlet provided in the living space of the vehicle because it is less volatile than the synthetic fragrance. By installing the air outlet, the scent can be quickly diffused in a limited space in the vehicle. Therefore, the vehicle fragrance device according to the present invention includes the suction member and the holding member, and a fixture for installing the container body filled with the fragrance component inside the air outlet in the vehicle. It has.

The vehicle fragrance device according to the present invention can spread the fragrance in the space by sucking up the fragrance component in the container body with the sucking member and diffusing the sucked up fragrance component. Therefore, it is not necessary to incorporate a device such as a motor or a fan, and unpleasant sounds such as driving sound of the device are not generated. In addition, even when used in an automobile, the cigar socket can be used without using the cigar socket in the car, so the cigar socket can be used for other purposes without worrying about battery consumption. Since the sucking member naturally sucks up the fragrance component by capillary action, there is no need to hang the fragrance component on tissue paper or the like, or to turn the instrument upside down each time it is used. Thus, a vehicle fragrance device that can reduce the labor of the user during use has been realized.

Since the suction member has a vertical hole or groove, it can suck up the fragrance component by capillary action, and diffuse the fragrance component sucked in the height direction throughout the suction member. Thus, it is possible to quickly diffuse the fragrance component. In addition, by forming the vertical hole or the vertical groove, air in the expanded container can be released even under a high-temperature environment, and an increase in atmospheric pressure can be prevented, so that excessive aroma components can be prevented from being sucked up. . Further, even if the atmospheric pressure in the container rises due to the ambient temperature or the like, and a large amount of fragrance component permeates the wicking member and oozes, the vertical hole or the vertical groove does not contain air and fragrance components. By existing as a passage, excess fragrance components can be returned to the container through the vertical hole or groove. Furthermore, by forming one vertical hole or vertical groove, even if the container falls or tilts, there is no air hole, so that the aromatic component in the container spills out. It can be lost. Therefore, by using the sucking member provided with one vertical hole or one vertical groove, it is possible to eliminate the waste of the fragrance component and solve the problem of spilling during the fall.

Also, if the cross-sectional area of the vertical hole or vertical groove in the wicking member is 4 mm ² or less (preferably 2 mm ² or less), there is a risk that the fragrance component will spill out if it is accidentally overturned. In addition to being able to reduce as much as possible, it can suck up an appropriate amount of fragrance components and does not waste fragrance components. Therefore, the cost of purchasing a new fragrance component can be saved, and a fragrance device for a vehicle with reduced running cost is provided. In particular, by setting the cross-sectional area of the vertical hole or vertical groove to 0.3 mm ² or more, particularly 0.5 mm ² or more, the fragrance component that has exuded to the upper end surface of the suction member due to an increase in internal pressure of the container body, It can return smoothly into the container. Therefore, it is desirable that the cross-sectional area of the vertical hole or the vertical groove is 0.5 mm ² or more and 4 mm ² or less, particularly 0.5 mm ² or more and 2 mm ² or less. However, the opening area of the longitudinal groove can be appropriately adjusted according to the viscosity of the fragrance component used.

In addition, by forming the circumferential groove communicating with the vertical hole or the vertical groove, it is possible to reliably prevent a situation in which the aromatic component overflowing due to the increase in the internal pressure of the container body is accommodated and drooping around the container body. Therefore, it can be suitably used in a vehicle having a particularly large temperature difference.

Furthermore, by providing a holding member formed of a resin material or the like between the suction member and the opening of the container body, the inside of the container body can be held liquid-tight. Therefore, even when the container is accidentally overturned or used in a vehicle where vibration or shaking occurs, the possibility of spilling the liquid aroma component can be reduced as much as possible. If the holding member is made of a material that absorbs and expands a fragrance component such as silicon, wrinkles or distortion may occur when the holding member is installed in the opening of the container. After the fragrance component is absorbed and expanded, a vehicle fragrance device that can be securely fixed to the opening of the container is realized.

Hereinafter, a vehicle fragrance device according to the present embodiment and a method of using the device will be specifically described with reference to the drawings.

As shown in FIG. 1 and FIG. 2, a vehicle fragrance device F according to the present embodiment includes a fragrance component 10 formed in a plant-derived liquid, a light shielding container 12 for housing the fragrance component 10, and a light shielding container. The holding member 15 accommodated in the opening 11 existing at the upper end of 12 and the elongate suction member 13 are configured.

In this embodiment, the aromatic component 10 uses an essential oil that is an essential oil component extracted from a plant. Therefore, if the kind of the fragrance component 10 is arbitrarily selected, an effect of calming and relaxing the user's brain activity and autonomic nerve by the scent that volatilizes and spreads in the space can be expected. Therefore, it can relieve stress and frustration during long distance driving and traffic jams, and can be used for safer driving. Since the fragrance component 10 is not added with a synthetic substance or adjusted in principle, it cannot be denied that the fragrance component 10 is easily affected by external influences such as sunlight. Therefore, in the present embodiment, the fragrance component 10 is accommodated in the light-shielding container 12 having a light-shielding property to prevent the fragrance component 10 from being altered. In particular, the light-shielding container is formed as a glass container, and therefore, the situation where the container itself is altered, such as dissolution by the fragrance component 10, can be eliminated.

Further, in order to suck up the fragrance component 10, a sucking member 13 formed in a rod shape using wood is used. Only one groove 14 extending in the length direction (penetrating in this embodiment) is formed on the outer peripheral surface of the suction member 10 so as to suck up the fragrance component 10 by capillary action. In the present embodiment, the groove 14 is formed with a width of 1 mm and a depth of 2 mm, and a cross-sectional area of 2 mm ² . This is because, when the cross-sectional area is formed with a cross-sectional area exceeding 4 mm ² , it is not possible to secure the suction height of the fragrance component 10 by capillary action, and even if it can be sucked up, it will be sucked up in large quantities, which is wasteful This is because the aromatic component 10 is consumed.

The width, depth, and cross-sectional area of the groove in the present embodiment will be described based on the following equation (1).

As shown in the above formula 1, the rising height h of the liquid level rising due to the capillary phenomenon becomes larger as the inner diameter (radius) of the capillary is smaller, and the liquid can be sucked higher. Therefore, by forming the groove 14 having an appropriate cross-sectional area in the above-described size, an appropriate amount of the fragrance component 10 can be sucked up, and the fragrance component 10 can be saved while enjoying a sufficient fragrance. it can.

Furthermore, a silicon holding member 15 for holding the suction member 13 is provided between the suction member 13 and the opening 11 of the light shielding container 12. The holding member 15 is formed in a cylindrical shape whose diameter is increased in a flange shape using silicon resin. As shown in FIG. 6, the holding member 15 expands by absorbing the fragrance component 10, and can be formed so as to be in close contact with the opening of the container after the expansion. At this time, the lower end side of the holding member 15 can be configured to swell to the diameter-expanded portion in the container during expansion and prevent a situation where it comes out. Further, the holding member can be formed by adjusting the initial size so that the suction member 13 can be slidably held in the length direction. Moreover, by expanding, the inside of the container can be kept liquid-tight, and the possibility that the liquid aroma component 10 leaks or spills can be reduced as much as possible.

In the vehicle fragrance device according to this embodiment, the inner diameter of the opening 11 of the light shielding container 12 is formed to be about 12.8 mm, and the outer diameter of the portion accommodated in the opening 11 of the holding member 15 is about 12 mm. Forming. Therefore, when installing in the opening part 11 of a container, an unintended deformation | transformation, a wrinkle, etc. do not generate | occur | produce, but it becomes possible to accommodate smoothly. On the other hand, the holding member 15 is liquid-tightly held in the opening 11 by absorbing the fragrance component 10 and expanding. Further, after the holding member 15 is expanded, the suction member 13 is slidably held in the length direction with respect to the opening 11 of the light shielding container 12, so that the amount of withdrawal of the suction member 13 is increased. It is possible to adjust the volatilization amount of the fragrance component 10 (that is, the intensity of the fragrance). Therefore, even when the temperature change in the car is severe, and even when getting on and off frequently and there is much ventilation, the volatilization amount of the fragrance component 10 can be arbitrarily adjusted, and it is more comfortable depending on the application and environment A vehicle fragrance device that can produce a comfortable interior space is realized.

Furthermore, when the suction member 13 is formed to be slidable in the length direction, a handle, a knob, or the like may be provided on the upper part. By providing a handle or knob on the upper part of the sucking member 13, it becomes easy to slide, and it is possible to reduce the possibility of dropping or dropping the fragrance device when sliding is performed. it can. However, when providing a handle, a knob, etc., it is desirable to form in the shape (or structure) which does not inhibit volatilization of the fragrance component 10 from the upper part of the said suction member 13.

Here, the effect of forming only one groove 14 on the suction member 10 will be described in detail based on the results of the following experimental examples. In this experimental example, as shown in FIG. 3 and Table 1 below, the usability of the fragrance device according to the type of the four types of suction members is verified, and compared with the vehicle fragrance device F according to the present embodiment. Verification was performed.

Specifically, as a comparative sample, a vehicle fragrance device using the following four suction members as shown in FIGS. 3A to 3D was manufactured.
As shown in FIG. 3A (hereinafter, also referred to as “pattern A”), a plurality of bamboo chins are combined to form a sucking member 13A for sucking and diffusing the aromatic component, and this is inserted into the opening of the light shielding container. Fragrance appliances,
As shown in FIG. 3B (hereinafter, also referred to as “pattern B”), a sucking member 13B that is formed in a columnar shape and is not provided with a circumferential groove or through hole is inserted into the opening of the light shielding container. A vehicle fragrance device,
As shown in FIG. 3C (hereinafter, also referred to as “pattern C”), a sucking member 13C in which wood is formed in a cylindrical shape and three thin cuts along the length direction are formed on the peripheral surface is formed as an opening of the light shielding container. A vehicle fragrance device inserted in the
As shown in FIG. 3D (hereinafter, also referred to as “pattern D”), a sucking member 13D, in which wood is formed in a cylindrical shape and two grooves along the length direction are formed on the peripheral surface, is opened in the light shielding container. Vehicle fragrance equipment inserted in the
The experiment was conducted by using the above-mentioned four kinds of sucking members and storing each 10 ml of the fragrance component in a light shielding container. In this experiment, the necessity of power supply and power for use ("cigar socket need"), consumption of fragrance components and strength of diffused fragrance ("economy / diffusive power"), use environment section (10 ℃ The presence or absence of liquid leakage of fragrance components and liquid sag (“liquid leakage”) at ˜60 ° C. was evaluated. The results are shown in Table 1 below.

As shown in Table 1, no cigar socket was required in any pattern. In the pattern A, the diameter of the plurality of bamboo ridges is small, and the surface area of the sucking member 13A as a whole is large. Therefore, the fragrance component is highly volatile, and all the fragrance component is consumed in about two weeks. Further, since the upper part of the container is not sealed, there is a high possibility that the aromatic component in the container will spill when it is vibrated or dropped.

Also, in Pattern B, the upper part of the container was sealed, and there was no fear of spilling the aromatic components inside. However, since no groove is formed in the sucking member, the ability to suck up the fragrance component is weak, and the fragrance component does not sufficiently penetrate into the open surface of the upper end, so the volatility is low and the fragrance does not spread.

In pattern C, the diffusing power and fragrance were moderate, and it lasted for about 3 weeks with 10 ml of fragrance component. However, due to the capillary phenomenon caused by the thin notches 30, a large amount of liquid is sucked up, so that the aromatic component overflows from the sucking member 13C when the temperature inside the vehicle rises.

Furthermore, in the pattern D, a suction member 13D in which two grooves 14 having a cross-sectional area of 2 mm ² are formed in the axial direction is used. As a result, the diffusion power and fragrance were moderate, and the fragrance component had 10 ml for about 3 weeks. However, due to the presence of a plurality of grooves, when the container is dropped, one groove functions as an intake hole for sucking outside air into the container, and fragrance components in the container are spilled.

On the other hand, in the vehicle fragrance device F according to the present embodiment, even when the interior of the vehicle vibrates or the container is dropped by using a suction member in which only one groove 14 is formed. There was no spillage of the aromatic components. Moreover, by forming the cross-sectional area of the groove 14 at 2 mm ² , it was possible to enjoy the spreading scent while enabling the saving of expensive scent components without sucking up a lot of scent components. Moreover, even if the fragrance component oozes from the upper end surface of the suction member due to the increase in the internal pressure of the container, it could be returned to the container through the groove 14.

From the above, in order to improve the diffusibility of the fragrance component, eliminate the wasteful consumption of the fragrance component, eliminate the outflow of the fragrance component when the container falls, and eliminate the fragrance component oozing due to the increase in internal pressure in the container It was confirmed that there was one groove or through-hole formed in the suction member, and the cross-sectional area was 4 mm ² or less (preferably 2 mm ² or less).

Next, a vehicle fragrance device F using a suction member according to another embodiment will be described with reference to FIG. That is, in the vehicle fragrance device F, as shown in FIG. 4, the groove 14 formed in the suction member 13 can be formed in various shapes. For example, in FIG. 4A, a groove 14 is formed in a sinusoidal shape with respect to the suction member 13. 4B, the groove 14 is formed in a triangular wave shape, and in FIG. 4C, the groove 14 is formed in a rectangular wave shape. In addition, as shown in FIG. 4D, a hole 44 may be formed in the central portion of the suction member 13. That is, only one groove 14 or hole 44 needs to be formed on the sucking member 13, and the shape of the groove (or hole) can be formed in an arbitrary shape. However, it is desirable that the cross-sectional area of the groove (or hole) is 4 mm ² or less (preferably 2 mm ² or less) so as not to suck a large amount of fragrance components unnecessarily. In consideration of manufacturing superiority, it is desirable that the groove formed in the suction member is linear. However, as shown in FIGS. 4A to 4C, when the groove is bent, the amount of aroma component stored in the groove increases. Therefore, when the suction member is slid in the length direction and lifted up, the fragrance component can be diffused for a long time even when the lower end side thereof is not in contact with the fragrance component in the container. Further, by bending the shape of the groove, even when the fragrance component in the container moves upward due to the vibration of the vehicle, the movement energy of the fragrance component going upward is absorbed by the bent groove. Thus, the possibility of being directly released from the groove can be eliminated.

FIG. 5 shows a usage example of the vehicle fragrance device F according to the present embodiment. In order to install the vehicle fragrance device F at the air outlet 50 in the automobile, a clip-type fixture 51 is used. The fixture 51 can be formed using a resin or the like. The vehicle fragrance device F supported by the fixture 51 has a suction member 13 that sucks an appropriate amount of the fragrance component 10 in the space. Can spread a sufficient scent. Moreover, the scent can further spread in the space by the air discharged from the air outlet of the vehicle. In particular, the suction member 13 is held by the holding member 15 so as to be slidable in the length direction. For this reason, when the vehicle interior temperature changes, the volatilization amount of the fragrance component 10 can be arbitrarily adjusted by sliding the sucking member 15 and adjusting the exposed area of the sucking member. Furthermore, the holding member 15 absorbs the fragrance component 10 and expands, so that the inside of the container can be held liquid-tight, and the possibility that the liquid fragrance component 10 leaks or spills can be reduced as much as possible. For this reason, even if you vibrate through an uneven road during driving or accidentally drop the container, you can concentrate on driving without worrying about spilling the aromatic component 10 inside. be able to.

Next, a vehicle fragrance device F according to another embodiment will be described with reference to FIGS. The vehicle fragrance device F shown in the embodiment of FIGS. 7 and 8 shows an embodiment in which a circumferential groove 20 for receiving the fragrance component 10 that has exuded on the upper end surface of the suction member 13 is formed.

In the vehicle fragrance device F shown in FIG. 7, the edge portion of the central opening of the holding member 15 into which the suction member 13 is inserted is cut out in a step shape, and the circumferential groove is formed with the outer periphery of the suction member 13 as the inner wall surface. It is configured to form. Therefore, in the vehicle fragrance device F of the present embodiment, by inserting the suction member 13 into the central opening of the holding member 15, between the stepped portion and the outer peripheral surface of the holding member 15, A circumferential groove 20 is formed. In the present embodiment, the circumferential groove 20 is formed to have a width and a depth of about 1 mm. However, regardless of the size, the circumferential groove 20 may be appropriately changed according to the use environment and the characteristics of the fragrance component to be used. it can.

The circumferential groove 20 is connected to a longitudinally extending groove 14 (hereinafter referred to as a “vertical groove”) formed on the outer peripheral surface of the suction member 13, and the fragrance accommodated in the circumferential groove 20. The component 10 can be returned to the light shielding container 12 through the longitudinal groove. Therefore, even if the internal pressure of the light shielding container 12 rises due to the ambient temperature and the fragrance component 10 in the container 12 oozes out to the upper end surface of the suction member 13, it is quickly collected in the circumferential groove 20 and again in the container 12 can be returned. Therefore, even if it is a case where it uses in the vehicle etc. with a large temperature change, it is the fragrance device F for vehicles which does not spill the fragrance component 10 which oozed out through a container main body.

In the vehicle fragrance device F shown in FIG. 8, the inner peripheral surface of the central opening of the holding member 15 in a state where the upper peripheral edge portion of the suction member 13 is cut into a step shape and inserted into the central opening of the holding member 15. The circumferential groove 20 is formed between the two. Therefore, the suction member 13 according to this embodiment is formed by reducing the diameter by about 2 mm from the upper end surface. Since the circumferential groove 20 is connected to the longitudinal groove 14 in the same manner as the vehicle fragrance device F shown in FIG. 7, the fragrance component 10 that has spread on the upper end surface of the suction member 13 is transferred to the circumferential groove 20. It is accommodated and can return to the internal space of the container body 12 through the longitudinal groove 14.

The vehicle fragrance device F shown in FIG. 9 relates to the vehicle fragrance device F shown in FIG. 7, and the length of the longitudinal groove 14 is particularly short. This vertical groove 14 discharges the gas in the internal space of the container main body and returns the fragrance component 10 that has oozed out to the end face of the suction member 13 into the container main body 12. It is enough to communicate. Therefore, the length of the vertical groove 14 is formed so as to extend until it is exposed below the holding member 15 in a state where the length is held by the holding member 15. In order to form the length of the longitudinal groove 14 in this way, it is necessary that the suction member 13 be formed of a material having a capillary phenomenon, such as wood or felt.

FIG. 10 shows an embodiment in which an exhaust port 14 for exhausting gas in the internal space of the container body 12 is formed in the container body 12. In the present embodiment, the exhaust port 14 is formed as a through-hole (bottle) opened in an area of about 2 mm ² or less so that the fragrance component 10 in the internal space does not leak. If it is such a size, as long as the suction member 13 is held in an airtight state in the opening of the container body, even if the vehicle fragrance device F is overturned, The aromatic component 10 is not leaked. Therefore, the exhaust port 14 for exhausting the expanded gas can be formed in the container body 12. However, it is necessary that the exhaust port 14 is opened in a region where the fragrance component 10 does not exist in the internal space of the container body 12.

FIG. 11 shows an embodiment of the vehicle fragrance device F in which the surface area of the upper end surface of the suction member 13 is increased. The vehicle fragrance device F according to any of the above-described embodiments has the suction member 13 so as to protrude from the opening of the container body 12 and secures a surface area for volatilizing the fragrance component. However, for example, when it is desired to diffuse fragrance in a wide space, it is desirable to further increase the surface area that contributes to diffusion. Therefore, in the present embodiment, a plurality of grooves 21 are formed on the upper end surface of the wicking member to increase the surface area that contributes to the diffusion of the fragrance component. By forming in this way, for example, even in a wagon car having a large indoor space, it is possible to quickly diffuse the fragrance, and it is possible to cope with users who prefer a stronger fragrance. In addition, since the groove | channel 21 formed in the upper end surface of the suction member 13 enlarges a surface area, as long as this objective is achieved, you may form a hole etc. not only in a groove | channel. In any of the above embodiments, the sucking member 13 is provided in contact with the bottom surface of the container 12 containing the fragrance component 10, so that the fragrance component in the container can be effectively used to the end. .

The vehicle fragrance device according to the present invention can be used to scent the boarding space in various vehicles such as automobiles, airplanes, and ships. Furthermore, it can be used not only for boarding spaces but also for deodorizing spaces such as luggage rooms.
