DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fragrance generating device, and more specifically, it applies a frequency vibration to a fragrance liquid by a vibrating element to evaporate the fragrance liquid into the air to be scented. The present invention relates to a scent generator.

[0002]

2. Description of the Related Art This type of scent generator is a method of generating a scent by bubbling in a fragrance liquid by supplying air (for example, see Japanese Patent Laid-Open No. 3-225129), or spraying the fragrance liquid with pressurized air. Compared to the type that does not require air for scent generation such as bubbling air or atomizing air, when adjusting air by the air conditioner is the target air for scenting, the adjustment state of the adjusted air is for scent generation. Although it has the advantage of avoiding the inconvenience of changing due to the mixing of air, the following methods have been used as a method to evaporate the perfume liquid into the air to be scented by applying frequency vibration.
There are ~ (d) methods.

(A) As disclosed in Japanese Patent Application Laid-Open No. 54-119114, in a state where a large amount of perfume liquid is stored in a tank, a vibrating element provided at a part of the bottom of the tank directly enters the stored liquid. A method of generating a fog of the fragrance liquid from the liquid surface of the stored fragrance liquid by radiating frequency vibration to the.

(B) As disclosed in Japanese Patent Application Laid-Open No. 54-119114, a method in which the perfume liquid is dropped directly onto the vibrating surface of the vibrating element and the dropped perfume liquid is atomized.

(C) A method in which the perfume liquid is supplied to a minute gap between the vibration plate connected to the vibrating element and the auxiliary plate to generate mist of the perfume liquid from a large number of holes formed in the vibration plate.

(D) A method in which a perfume liquid is supplied to a fine tube which is vibrated by a vibrating element, and fine droplets of the perfume liquid are caused to fly from the fine holes formed in this fine tube.

[0007]

However, in the method of (a), due to the vibration diffusion in a large amount of stored liquid and the vibration reflection in the tank, the mist generated from the perfume liquid has a high uniformity of particle diameter. Although a large amount of fog can be generated, when changing the scent, it is necessary to replace all of the large amount of the stored fragrance liquid in the tank equipped with the vibrating element, and there is a problem in that it is difficult to respond to changing the scent.

However, the perfume liquid in the tank is made extremely small so that the perfume liquid exists in a thin film state at the bottom of the tank, and the perfume liquid in the thin film state is directly fed from the vibrating element at a part of the bottom of the tank. When the frequency vibration is applied, the deviation of the vibration distribution in the thin-film fragrance liquid becomes large, and the variation in the particle size in the generated fog becomes noticeable. The disadvantage that the evaporated droplets remain for a long time tends to occur.

On the other hand, in the method (b), although the scent can be easily changed and a mist having a high particle size uniformity can be generated, the fragrance liquid is dripped on the vibrating surface of the vibrating element, so that the drip is dropped. There is a problem that the amount of fog is limited to a small amount relative to the vibration generating capacity of the vibrating element and the fragrance generating capacity is low, but only increasing the area of the vibrating surface. Using a large vibration element for the purpose of
Cost loss increases.

On the other hand, in the method of (c), the scent can be easily changed by switching the fragrance liquid to be supplied to the minute gap between the diaphragm and the auxiliary plate, and a small vibration can be achieved by adopting the diaphragm. Although a large amount of fog can be generated using the element, the vibration distribution from the vibrating element to the diaphragm and the vibration in the plate material of the diaphragm causes uneven distribution of vibration, increasing the plate area of the diaphragm. The greater this tendency is, the larger the variation in particle size in the generated fog is, as compared with the method of radiating frequency vibration into a large amount of stored liquid or the method of dropping perfume liquid on the vibration surface itself of the vibration element. Therefore, there is a problem that the inconveniences such as the uneven scent and the remains of the non-evaporated droplets are likely to occur.

Further, in the method (d), the scent can be easily changed by switching the perfume liquid to be supplied to the fine tube, but since the droplets are ejected from the fine holes of the fine tube one by one, the droplets are dropped. However, there is a problem that the scent generation ability is lower than that of a method in which a large number of liquid droplets are generated in a fog state.

In view of the above situation, the main problem of the present invention is to effectively solve each of the above problems by imparting the vibration generated by the vibration element to the fragrance liquid and adopting a rational vibration propagation structure. There is a point to do.

[0013]

The scent generating device according to the present invention is characterized in that a oscillating element applies a frequency vibration to a scent liquid to evaporate the scent liquid into the air to be scented.
A tray-shaped vibrating body that receives the supply of the perfume liquid from the perfume supply means is arranged such that a part of the vibrating body is immersed in the stored water in the water tank, and the vibrating element directs the frequency vibration toward the vibrating body. It is located at the bottom of the water tank so as to radiate it into the stored water in the water tank.

[0014]

With the above-mentioned characteristic configuration, in a state where a part of the tray-like vibrated body is immersed in the stored water in the water tank, a frequency vibration is applied toward the vibrated body from the vibrating element at the bottom of the water tank to the stored water in the water tank. By radiating, the tray-shaped vibrated body is vibrated by the vibration propagation in the stored water. Then, due to the vibration of the vibrating body, frequency vibration is applied to the perfume liquid supplied from the perfume supply means to the vibrating body to vaporize the perfume liquid in the form of fine particles to thereby evaporate the perfume liquid. The air to be scented is efficiently evaporated into the air to be scented.

[0015]

According to the present invention, while the size of the vibrating body to which the perfume liquid is supplied is kept large, and the vibrating element is small-sized to be arranged at a part of the bottom of the water tank, With an appropriate amount of stored water, it is possible to vibrate the entire tray-shaped vibrated body in a state where the vibration distribution is less biased, by vibrating and diffusing in the stored water and by vibrating and reflecting in the tank.

With this, while using a small vibration element effectively avoiding cost loss,
Further, the amount of the perfume liquid in the tray-shaped vibrating body is limited to a small amount so that the scent can be easily changed only by switching the perfume supplied from the perfume supply means, while the fog generated from the perfume liquid is changed. As a result, it is possible to generate a large amount of mist with a highly uniform particle size with a sufficient size of the vibrated body and a vibration distribution with little deviation, and effectively prevent the inconveniences such as scent unevenness and remaining unevaporated droplets. It is possible to obtain a high scent generating ability.

In other words, according to the present invention, in the above-mentioned method (a), the atomized portion of the liquid surface of the large amount of the stored perfume liquid is in the form of a tray which receives the supply of the perfume liquid from the perfume supply means. A small vibrating element that is placed in a part of the bottom of the tank by replacing it with a vibrating body and replacing the part that contributes to the diffusion of radiation vibration from the vibrating element and the reflection in the tank with the stored water in the tank. While utilizing the (a) method that can generate a large amount of mist with high particle size uniformity, it is necessary to replace a large amount of the stored perfume liquid when changing the scent. Therefore, compared with each of the above-mentioned methods (a) to (d), the characteristic surface of the fog generated,
The scent generator is comprehensively superior in terms of scent generation capacity, cost, and fragrance changeability.
