Description

本発明は、液体をミスト化することができるミスト発生装置およびミスト発生方法に関する。   The present invention relates to a mist generating apparatus and a mist generating method that can mist a liquid.

芳香発生装置として、超音波振動を利用したミスト発生装置が提案されている（特許文献１参照）。このミスト発生装置においては、少量の芳香性のある精油を大量の水に添加したものをミスト化させている。   As a fragrance generating apparatus, a mist generating apparatus using ultrasonic vibration has been proposed (see Patent Document 1). In this mist generating device, a small amount of aromatic essential oil added to a large amount of water is misted.

特開２０１０−８８８５１号公報JP 2010-88851 A

上記の文献に開示された技術によれば、大量の水に希薄化された精油をミスト化するため、精油の芳香を継続的に漂わせたいときには、大量の水もミスト化する必要があると共に、連続的に行う必要がある。また、水を貯えるタンクも必要であり、ミスト発生装置の小型化に限界があると共にミスト発生装置を転倒させた場合の水漏れによるショートなどの問題からも逃れることができない。さらに、芳香とは関係のない水もミスト化するため、その分だけ、超音波振動子を駆動するための電力も必要となってくる。   According to the technique disclosed in the above-mentioned literature, in order to mist the essential oil diluted in a large amount of water, when it is desired to continuously drift the aroma of the essential oil, it is necessary to mist a large amount of water as well. Need to be done continuously. Further, a tank for storing water is also necessary, and there is a limit to downsizing the mist generating device, and it is impossible to escape from problems such as a short circuit caused by water leakage when the mist generating device is turned over. Furthermore, since water that has nothing to do with fragrance is also misted, electric power for driving the ultrasonic transducer is required accordingly.

本発明の目的は、小型化を図ることができると共にミスト化したい液体を効率的にミスト化することができるミスト発生装置およびミスト発生方法を提供することを目的とする。   An object of the present invention is to provide a mist generating apparatus and a mist generating method capable of downsizing and efficiently misting a liquid to be misted.

Since the porous vibrating body is porous, it can hold a liquid. For this reason, the porous vibrating body holding the liquid receives ultrasonic vibration energy and vibrates, so that the liquid becomes mist. Since the porous vibrator has a porous shape, the contact area with the liquid is large, and the spray efficiency is high. In particular, when the essential oil is atomized, it is not necessary to dilute the essential oil with water, so a water tank is not required, and the mist generator can be downsized.

以下、本発明の好適な実施の形態について詳細に説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail.

図１は、ミスト発生装置の例を示す図である。   FIG. 1 is a diagram illustrating an example of a mist generating apparatus.

１．構成例
本実施の形態に係るミスト発生装置１００は、超音波振動子１０と、多孔質振動体２０とを含む。 1. Configuration Example A mist generating apparatus 100 according to the present embodiment includes an ultrasonic transducer 10 and a porous vibrating body 20.

超音波振動子１０は、公知のものを適用することができる。超音波振動子１０の大きさは、多孔質振動体２０の大きさおよびミスト発生装置１００の求める能力を考慮して決めることができる。   As the ultrasonic transducer 10, a known one can be applied. The size of the ultrasonic transducer 10 can be determined in consideration of the size of the porous vibrating body 20 and the ability required of the mist generating device 100.

多孔質振動体２０は、超音波振動子１０に隣り合う位置に設けられ、かつ、超音波振動子１０の超音波振動エネルギーを受けて振動する。   The porous vibrator 20 is provided at a position adjacent to the ultrasonic vibrator 10 and vibrates in response to the ultrasonic vibration energy of the ultrasonic vibrator 10.

多孔質振動体２０の形状及び大きさは、ミスト発生装置１００の大きさ及びそのミスト発生能力を考慮して決められるが、たとえば、２〜３ｃｍ角の立方体とすることができる。また、多孔質振動体２０は、円柱状であってもよい。多孔質振動体２０の材質は、多孔質（具体的には粒状空孔の集合体或は微細なパイプ状構造）のもので、超音波振動子１０の振動エネルギーを受けて振動するものあれば特に限定されないが、剛性の高い材質が好ましく、たとえばアルミニウム、ステンレスなどの防錆素材や硬質セラミックなどを挙げることができる。多孔質振動体２０は、超音波振動子１０に固定されている。固定の方法としては、固定できるものであれば限定されないが、超音波振動子１０の振動エネルギーを損失無く伝える接着方法が好ましく、たとえば、接着剤による固着を挙げることができる。   The shape and size of the porous vibrating body 20 are determined in consideration of the size of the mist generating device 100 and its mist generating capability, and may be a cube of 2 to 3 cm square, for example. The porous vibrating body 20 may be cylindrical. The material of the porous vibrating body 20 is porous (specifically, an aggregate of granular vacancies or a fine pipe-like structure) and can vibrate upon receiving the vibration energy of the ultrasonic vibrator 10. Although not particularly limited, a highly rigid material is preferable, and examples thereof include a rust preventive material such as aluminum and stainless steel, and hard ceramic. The porous vibrating body 20 is fixed to the ultrasonic transducer 10. The fixing method is not limited as long as it can be fixed, but an adhesion method that transmits the vibration energy of the ultrasonic transducer 10 without loss is preferable, and examples thereof include fixing with an adhesive.

多孔質振動体２０の孔径は、たとえば、１０〜１００μｍとすることができる。孔の密度は、製造可能な範囲で密なものとするとよい。   The pore diameter of the porous vibrating body 20 can be set to 10 to 100 μm, for example. The density of the holes should be as close as possible within the range that can be produced.

超音波振動子１０を制御する制御部（図示せず）を設けることができる。制御部は、たとえば、ＣＰＵ、ＲＯＭおよびＲＡＭから構成されることができる。   A control unit (not shown) for controlling the ultrasonic transducer 10 can be provided. The control unit can be composed of, for example, a CPU, a ROM, and a RAM.

超音波振動子１０を駆動するための電源（図示せず）は、ＡＣ電源であっても、乾電池であってもよい。   A power source (not shown) for driving the ultrasonic transducer 10 may be an AC power source or a dry battery.

２．使用方法
まず、多孔質振動体２０に精油を滴下し、多孔質の毛細管現象を利用して、多孔質振動体２０に吸収させる。多孔質振動体２０への精油の滴下は、人の手によりスポイトなどを利用して行ってもよいし、又は、公知の滴下装置などの供給装置を用いて行ってもよい。滴下する精油の量は、多孔質振動体２０の大きさによっても異なるが、多孔質振動体２０が２〜３ｃｍ角の立方体からなる場合には、たとえば、２〜３ｍｌとすることができる。 2. Method of Use First, essential oil is dropped onto the porous vibrating body 20 and is absorbed by the porous vibrating body 20 using the porous capillary phenomenon. The dripping of the essential oil onto the porous vibrating body 20 may be performed using a dropper or the like by a human hand, or may be performed using a supply device such as a known dripping device. The amount of the essential oil to be dropped varies depending on the size of the porous vibrating body 20, but when the porous vibrating body 20 is a cube of 2 to 3 cm square, it can be set to 2 to 3 ml, for example.

超音波振動子１０を駆動させて、超音波振動エネルギーを多孔質振動体１０に伝達し、精油をミスト化する。   The ultrasonic vibrator 10 is driven to transmit ultrasonic vibration energy to the porous vibrating body 10 and mist the essential oil.

超音波振動子１０の駆動に当たって、その超音波振動子１０の共振周波数の付近の高周波電圧を印可する。この駆動において、多孔質振動体２０には必要量の精油のみしかないため、空焚きを防ぐという観点からと省電力化のため、パルス的な間欠駆動とするとよい。なお、正弦波又は矩形波の発信器から発信された高周波を電力増幅器により増幅する連続波での駆動であってもよく、この場合には、発信器を断続的にｏｎ−ｏｆｆしてもよい。   In driving the ultrasonic transducer 10, a high-frequency voltage in the vicinity of the resonance frequency of the ultrasonic transducer 10 is applied. In this driving, since the porous vibrator 20 has only a necessary amount of essential oil, pulsed intermittent driving may be used from the viewpoint of preventing idling and power saving. Note that it may be driven by a continuous wave that amplifies a high frequency wave transmitted from a sine wave or rectangular wave transmitter by a power amplifier. In this case, the transmitter may be intermittently turned on and off. .

３．作用効果
本実施の形態によれば、たとえば、次の作用効果を奏することができる。 3. Effects According to the present embodiment, for example, the following effects can be achieved.

本実施の形態においては、多孔質振動体２０が多孔質形状を有しているため、液体を保持することができ、液体との接触面積が大きい。このため、液体のミスト化効率が高い。このため、多孔質振動体２０に直接に精油を滴下し、その精油をミスト化することができる。このため、従来、大量の水に希薄化された精油をミスト化していたところ、本実施の形態においては、精油を大量の水に希薄化させる必要がない。したがって、精油のみのミスト化を図ることができため精油の噴霧効率を高めることができると共に、水を貯えるタンクも不要になるため、ミスト発生装置の小型化を図ることができる。また、水タンクも不要になるため、機器を転倒させた場合の水漏れによる問題も回避することができる。   In the present embodiment, since the porous vibrating body 20 has a porous shape, the liquid can be held and the contact area with the liquid is large. For this reason, the misting efficiency of the liquid is high. For this reason, essential oil can be dripped directly into the porous vibrating body 20, and the essential oil can be mist-ized. For this reason, conventionally, the essential oil diluted in a large amount of water was misted. In the present embodiment, it is not necessary to dilute the essential oil in a large amount of water. Therefore, it is possible to make the mist only of the essential oil, so that the efficiency of spraying the essential oil can be increased, and the tank for storing the water becomes unnecessary, so that the mist generating device can be downsized. Further, since a water tank is not required, a problem caused by water leakage when the device is overturned can be avoided.

さらに、水をミスト化させる必要がないため、使用電力量を少なくすることができると共に、精油の蒸散効率を高めることができるので、低電力の間欠駆動が可能となる。このため、電源として、ＡＣ電源でなくとも、乾電池などで駆動させることもできる。また、超音波振動子１０の間欠駆動で十分な蒸散が可能となり、超音波振動子の空焚きによる破損を防止することができる。   Furthermore, since it is not necessary to mist water, the amount of power used can be reduced and the efficiency of transpiration of the essential oil can be increased, so that low-power intermittent driving is possible. For this reason, the battery can be driven by a dry battery, etc., instead of an AC power supply. Further, sufficient evaporation can be achieved by intermittent driving of the ultrasonic vibrator 10, and damage to the ultrasonic vibrator due to airing can be prevented.

本実施の形態は、本発明の範囲内において種々の変形が可能である。   The present embodiment can be variously modified within the scope of the present invention.

ミスト化させる液は、精油のみならず、水溶液などの他の液体であってもよい。   The liquid to be mist may be not only essential oil but also other liquid such as an aqueous solution.

本発明は、たとえば、芳香性のある精油をミスト化する芳香発生装置として適用することができる。   The present invention can be applied, for example, as an aroma generating device that mists essential oils with aroma.
