DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-operated fragrance used in a room or a toilet.

[0002]

2. Description of the Related Art Conventionally, fragrances have been used to make fragrances drift in rooms and toilets. This fragrance includes
There is known a liquid fragrance in which a solid fragrance or liquid fragrance liquid in which a fragrance is emulsified and gelled is stored in a container, sucked up by a core material, and volatilized by volatilizing paper or the like. In recent years, unglazed type fragrances have also been put on the market that allow aromatic liquid to permeate and volatilize porous bodies such as unglazed. The fragrance used in these fragrances is a mixture of many fragrance components having different volatility, which are generally called top notes, middle notes, and base notes. These fragrances are used by being placed in an arbitrary place while being released to the atmosphere.

On the other hand, a timer, a sensor, an electric fan, and the like are incorporated in the container, and the electric fan is driven at regular time intervals or only when the sensor detects the presence of a person to discharge the fragrance of the fragrance to the outside of the container. Are also known.

[0004]

However, the conventional fragrance has the following problems. In other words, since the fragrance is released to the atmosphere and used in the state of natural emission,
Dissipation of the extra scent accelerates the consumption of the fragrance. In addition, the top note component, which is easy to volatilize, volatilizes first, while the base note component is hard to volatilize, so that the proportion of the fragrance component changes greatly with the passage of time. As a result, the "fragrance titer", which is an index of the strength of the scent, or the quality of the scent, the so-called "scent quality", is remarkably changed, and there is a drawback that the predetermined scent cannot be kept constant.

As means for solving this kind of problem, a method has been proposed in which a large number of top notes, which are easy to volatilize, are compounded, or a water-soluble solvent is compounded (Japanese Patent Laid-Open No. Hei 5-161698). However, even these methods have been insufficient to prevent the aging of the aroma titer and flavor. Further, as a method of volatilizing a fragrance with a constant fragrance tone as much as possible, fragrance components are divided into two or three groups according to the degree of volatilization, and the volatilization speed of each group is adjusted by the volatilization area (Japanese Patent Publication No. 58-50740, JP-A-1-256966 is known. However, since this method must give a different volatilization area for each group,
There is a disadvantage that the volatilization container becomes complicated.

On the other hand, in the case of a fragrance incorporating a timer and a sensor, changes in fragrance titer and fragrance over time are somewhat suppressed, but are still insufficient. Also,
There have been problems such as that the container is too large and the place of use is restricted, and noise is generated when the electric fan is driven.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and the consumption of the fragrance is slow, so that a certain scent can be maintained even when used for a long period of time. It is an object of the present invention to provide a fragrance with less odor.

In order to achieve the above object, an aroma device according to a first aspect of the present invention comprises: a sealed container provided with an air intake and a fragrance outlet; An electric fan that discharges the fragrance generated from the fragrance from the fragrance outlet to the outside of the closed container,
A drive means for rotating the electric fan, and a sensor for operating the electric fan by outputting a signal to the drive means when the presence of a person is detected, wherein the top note 0 is contained in the fragrance.
-30% by weight, 50-100% by weight of middle notes, and 0-30% by weight of base notes.

According to a second aspect of the present invention, there is provided a fragrance device comprising: a sealed container provided with an air intake and a fragrance outlet; a fragrance contained in the sealed container; and a fragrance generated from the fragrance. Equipped with an electric fan that discharges the air from the fragrance outlet to the outside of the closed container, a driving unit that rotates the electric fan, and a sensor that sends a signal to the driving unit when the presence of a person is detected and operates the electric fan The electric fan rotates in the vertical direction.

According to a third aspect of the present invention, in the fragrance device according to the first or second aspect, when a signal transmitted from the sensor is input to the driving device, the driving device is controlled for a predetermined time. A timer is provided.

The fragrance device according to the first and second aspects of the present invention has a configuration in which the fragrance is stored in a closed container and the electric fan is operated by the driving means when the sensor detects the presence of a person. Therefore, when there is no person at the place where the fragrance is placed, the scent is trapped in the closed container, and when there is a person, the scent is released from the scent outlet to the outside of the closed container.

As demonstrated below using experimental data, in the aroma device according to the first aspect, the fragrance titer and flavor are improved by optimizing the component ratio of the compounded fragrance in the fragrance. It can last for a long time. In the fragrance device according to the second aspect, since the electric fan is configured to rotate in the vertical direction, noise generated from the electric fan can be reduced. In the fragrance device according to the third aspect, by providing a timer, the electric fan is rotated for a predetermined time when the sensor detects the presence of a person, and then the electric fan is stopped. Can be.

Next, the method of use and operation of the fragrance device 1 having the above configuration will be described. After setting the fragrance container 3 and the dry battery 7 inside the fragrance device 1, the fragrance device 1 is placed in an arbitrary place such as a room. When the sensor 6 of the fragrance device 1 detects the presence of a person, the sensor 6 sends a signal to a switching element and a timer in the power supply circuit to operate the motor 5, and the sirocco fan 4 starts rotating. Then, the fragrance contained in the fragrance 1 is blown out from the fragrance outlet 11 on the front of the fragrance 1. At this time, the display lamp 24 is turned on at the same time, indicating that the fragrance device 1 is operating. In the case of the present embodiment, the switching element is operated by the action of the timer, and the motor 5 and the power supply circuit are connected for a certain period of time. After a certain period of time, the sirocco fan 4 stops, and Also stops.

Thus, the fragrance device 1 of the present embodiment is
Unlike a conventional open-type fragrance, the fragrance is housed in a closed housing 2. In addition, since the sensor 6 for detecting the presence of a person and the sirocco fan 4 activated by a signal from the sensor 6 are provided, the fragrance is blown out of the fragrance device 1 only when a person is present, and the fragrance device 1 is provided when no person is present. The inside is filled with aroma. Therefore, in the fragrance device 1, since the fragrance is consumed slowly, the fragrance can be prolonged. In addition, only the top note component that is easy to volatilize is prevented from volatilizing quickly, and the ratio of the fragrance component does not change with the elapse of time, so that the predetermined scent can be kept constant for a long period of time.

Further, the component ratio of the top note, the middle note, and the base note in the fragrance F is set to 0 to 3
By optimizing 0% by weight, 50 to 100% by weight of middle notes, and 0 to 30% by weight of base notes, the fragrance titer and fragrance can be maintained for a longer period. Further, since the sirocco fan 4 is configured to rotate in the vertical direction, noise generated from the sirocco fan 1 can be reduced. These effects will be described in detail in the following embodiments.

In the fragrance device 1 of the present embodiment, since the dry battery 7 is built in as a power supply for the sirocco fan 4, it is easy to handle.
It also has advantages such as.

The technical scope of the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention. For example, in the present embodiment, a timer is provided in the power supply circuit on the substrate 23, and the sirocco fan 4 is rotated for a certain period of time after the sensor 6 detects the presence of a person by the action of the timer. Instead of this configuration, a configuration may be adopted in which the fan continues to rotate while the sensor detects the presence of a person without providing a timer. The types of the electric components of the fragrance device of the present invention, such as a fan, a motor, a sensor, and a timer, and the shape of the housing are not limited to those in the present embodiment, and the design can be changed as appropriate. Further, the power source for driving the motor is not limited to a dry battery, but may be another type of battery or an AC power source.

[0028]

Embodiments of the present invention will be described below. Here, the fragrance titer and fragrance were evaluated using the fragrance of the above-described embodiment and a conventional commercially available fragrance, and using samples in which the fragrance component ratio was variously adjusted. Further, with respect to the fragrance device of the present embodiment, by changing the rotation direction of the electric fan,
The magnitude of the noise generated when the electric fan was driven was evaluated.

(First Embodiment) Table 1 below shows the types of experimental samples used in the first embodiment and the evaluation results. The types of the experimental samples are summarized as follows. Examples 1 and 2, the fragrance of the present invention, in which the ratio of the fragrance components of the top note (limonene), middle note (citronellol), and base note (hexylcinnamic aldehyde) was changed. Comparative Example 1 ... the present invention The rotation direction of the electric fan in the fragrance was changed to the horizontal direction. Comparative Example 2 The fragrance itself was the same as that of the present invention.
%, Base note 30% by weight, and those outside the scope of the present invention. Comparative Examples 3 to 5: Unglazed type fragrances with different flavor component ratios. Comparative Example 6: Commercial sheet type Aroma, Comparative Example 7 A commercially available gel-type aroma.

As an evaluation method, 10 panelists compared a sample which had been stored for 1 month at room temperature with a blank product (at the start of use). The evaluation criteria in Table 1 are as follows: ８０: 80% or more of the panelists were judged to be equivalent to blank products, Δ: 50% to 79% of the panelists were judged to be equivalent to blank products, ×: 49% or less of the panelists were blank products It is determined that is equivalent to. Further, the loudness of noise when the electric fan is driven (one month storage at room temperature) is as follows: ○: almost no sound, △: slightly sound, ×: considerably loud sound.

[0031]

[Table 1]

As shown in Table 1, there is a clear difference between the aroma containers of the present invention (Examples 1 and 2) and the conventional fragrances (Comparative Examples 3 to 7) in the evaluation of fragrance titer and fragrance. According to the fragrance device of the present invention, it has been proved that deterioration of fragrance titer and fragrance, which have conventionally been problems, can be sufficiently improved. Moreover, even though the aroma itself is the same as that of the present invention, the ratio of the fragrance component is 50% by weight of the top note, 20% by weight of the middle note, and 30% by weight of the base note. In this case, it was found that the aroma titer and flavor were slightly deteriorated as compared with Examples 1 and 2. Further, in Comparative Example 1 in which the rotation direction of the electric fan was horizontal, a large noise was generated from the electric fan, whereas in Examples 1, 2 and Comparative Example 2 in which the rotation direction of the electric fan was vertical, Has been demonstrated to be almost eliminated.

(Second Embodiment) The second embodiment is an evaluation of the fragrance titer and fragrance when the composition of the fragrance is more finely changed after using the fragrance of the present invention. And Table 2 below
Shows the types of experimental samples used in the second example and the evaluation results. The types of the experimental samples are summarized as follows. Examples 1 and 2, the fragrance of the present invention, wherein the ratio of the fragrance component of the top note (limonene), middle note (citronellol), and base note (hexylcinnamic aldehyde) was changed within the scope of the present invention. Examples 3 and 4 to which the 3-methyl-3-methoxybutanol was added to the fragrance of Examples 1 and 2 above (for example, in Table 2, Example 3 had 5% by weight of top note, 35% by weight of middle note, The base note is 10% by weight,
This value is the component ratio as viewed from the whole fragrance. The component ratio in the fragrance is 10% by weight of the top note, 70% by weight of the middle note, and 20% by weight of the base note, which is within the range of the fragrance component ratio of the present invention. Examples 5 and 6 include polyoxyethylene alkyl ether, polyoxyethylene nonyl phenyl ether, preservative, and purified water. Comparative Example 1 In which the fragrance component ratio of the top note, the middle note, and the base note was changed out of the range of the present invention. Comparative Example 2… In addition, 3-methyl 3-methoxy was added to the fragrance of Comparative Example 1. Butanol added, Comparative example 3 ... A flavor obtained by adding polyoxyethylene alkyl ether, polyoxyethylene nonylphenyl ether, preservative, and purified water to the fragrance of Comparative example 1. The evaluation method is the same as in the first embodiment.

[0034]

[Table 2]

Table 2 shows that Examples 1 to 6 all show good performance, while Comparative Examples 1 to 3 show slightly inferior performance. From this fact, in the case where the fragrance is prepared only with the fragrance, the case where other components are added to the fragrance, and the ratio of the components viewed only in the fragrance is the top note 0.
As long as the conditions of 30 to 30% by weight, 50 to 100% by weight of middle notes and 0 to 30% by weight of base notes are satisfied, it is demonstrated that the fragrance titer and the fragrance can maintain a good state.

(Third Embodiment) The third embodiment is an evaluation of the fragrance titer and fragrance when the fragrance of the present invention and a commercially available fragrance are used again and the composition of the fragrance is changed. Table 3 below shows
10 shows the types of experimental samples used in the third example and evaluation results. The types of the experimental samples are summarized as follows. Examples 7 and 8: The fragrance of the present invention, in which the ratio of perfume components of top note (limonene), middle note (citronellol) and base note (hexylcinnamic aldehyde) was changed within the scope of the present invention, and polyoxyethylene was used. To which alkyl ether, polyoxyethylene nonyl phenyl ether, carrageenan, preservative, and purified water were added (as described in the second embodiment, in Table 3, Example 7 shows 0.5% by weight of top notebook , Middle note 3.5% by weight and base note 1.0% by weight, but among the fragrances, top note 10% by weight, middle note 70% by weight and base note 20% by weight, the fragrance of the present invention Comparative Example 4: The fragrance itself is the same as that of the present invention.
The fragrance of the present invention has a fragrance component ratio of 2.5% for top notes (50% by weight in fragrance), 1.0% for middle notes (20% by weight for fragrance), and 1.5% for base notes (30% by weight in fragrance). Comparative examples 5 to 8: commercially available unglazed type fragrances with different flavor component ratios and additives other than fragrance, Comparative examples 9 and 10: commercially available liquid type Perfumes with different perfume component ratios, Comparative Examples 11 and 12: Commercially available gel-type perfumes with different perfume component ratios. The evaluation method is the same as in the first and second embodiments.

[0037]

[Table 3]

According to this embodiment, the results of the first and second embodiments can be reconfirmed with respect to the performance of the fragrance of the fragrance. As is evident from Table 3, when using the type of the present invention as the fragrance, when the fragrance was prepared only with the fragrance, and when other components were added to the fragrance, It has been demonstrated that, when the component ratio in the fragrance satisfies the conditions of the present invention, a favorable state of fragrance titer and fragrance can be maintained.

If only the effect of maintaining a constant scent is required, only the component ratio of the compounded fragrance should be set within the scope of the present invention regardless of the rotation direction of the electric fan. The configuration corresponds to the fragrance device according to the first aspect. If only the effect of reducing noise is required, it is only necessary to make the rotation direction of the electric fan vertical. The configuration corresponds to the fragrance device according to claim 2.

[0040]

As described above in detail, the fragrance device of the present invention is different from the conventional open type fragrance in that the fragrance is contained in a closed container. In addition, since it has a sensor that detects the presence of a person and an electric fan that operates according to the signal from the sensor, the fragrance is blown out of the fragrance only when there is a person, and the fragrance is trapped in the fragrance when there is no person State. Furthermore, the component ratio of the compounded fragrance in the fragrance was optimized. As a result, in the fragrance device of the present invention, the consumption of the fragrance is slow and the fragrance can last longer. Then, since the ratio of the fragrance component does not change with the passage of time, the predetermined scent can be kept constant. Further, since the electric fan rotates in the vertical plane, noise generated from the electric fan can be reduced.
