Description

The present invention is an ultrasonic fog generator for releasing chemical substances used in daily life, such as fragrances, pharmaceuticals, and disinfectants, in a mist. It relates to the device to be generated.

Below, the conventional problem is demonstrated about the ultrasonic atomizer which contains a fragrance | flavor in a mist and discharge | releases a fragrance | flavor as an example as a chemical substance.

For example, an apparatus for generating a mist by placing a plate-like ultrasonic transducer in a liquid reservoir and vibrating the liquid at high speed with ultrasonic waves is disclosed in, for example, an ultrasonic atomizer disclosed in Japanese Patent Application Laid-Open No. 2003-245580, It is disclosed in a humidifier. Since the vibrator can be vibrated at a high frequency exceeding 1 MHz, the particle diameter of the mist can be made extremely small. Considering application to a fragrance generator, it can be a device with good olfactory characteristics.

However, when a plate-like ultrasonic vibrator is driven at a high frequency, if there is no liquid on the vibration surface, the ultrasonic wave is reflected by the surface of the element, and the ultrasonic vibrator itself generates heat and becomes high temperature. .

In the case of a piezoelectric element, when the element exceeds a predetermined temperature, the piezoelectric polarization characteristics deteriorate, or the element itself breaks and breaks. Although it depends on the material, the polarization deteriorates when the element temperature is about 80 ° C. or higher, and may break when the device temperature is about 150 ° C. or higher. There is a similar problem even in an element using the magnetostrictive effect.

Therefore, it is general to use an ultrasonic vibrator that is driven at a high frequency so that a sufficient liquid always exists on the vibration surface. In other words, mist generating devices that atomize a small amount of liquid with high frequency ultrasonic waves have not been commercialized so far in the field of household goods because there is a risk that the ultrasonic transducer will be destroyed.

Many of the ultrasonic fog generators currently commercialized for home use atomize water or one kind of fragrance-containing liquid. Further, most of the methods are atomization in a state where a sufficient amount of the atomization target liquid is supplied onto the ultrasonic vibrator.

However, in an apparatus in which an ultrasonic vibrator is immersed and atomized with many fragrance-containing liquids, there is a problem that the fragrance is wasted and the range of liquid to be scattered is wide, so that the inside of the apparatus is contaminated.

As a method of atomizing a small amount of liquid while reducing the risk of the ultrasonic vibrator breaking in an empty state, for example, Japanese Patent Laid-Open No. 3-65264, Japanese Patent No. 3547132 discloses a vibration surface as an ultrasonic propagation medium. And a method of using a liquid container with an ultrasonic wave passage film so as to be in contact with the ultrasonic propagation medium is proposed. There is a feature that the fragrance-containing liquid can be put into the liquid container and atomized, and the type of mist can be changed by replacing the liquid container.

However, when an ultrasonic wave passage film is used, there is a problem that ultrasonic energy is lost. Further, since the ultrasonic propagation medium is exposed and exposed to air in a state where the liquid container with the ultrasonic wave passing film is removed, there is a problem that the liquid is spoiled or dirty. Cleaning is troublesome.

In order to solve the latter problem, the present inventor has invented an apparatus that uses two ultrasonically passing films in Japanese Patent Application No. 2006-220886. The first ultrasonic passage film is provided on the surface of the ultrasonic propagation medium, the second ultrasonic passage film is provided on the bottom of the liquid container, and the liquid container is installed so that the two ultrasonic passage films are in contact with each other. To use. The ultrasonic waves pass through the two membranes and atomize the liquid.

This device has excellent features such as easy cleaning, good maintainability, and easy perfume switching, but it has a thick ultrasonic passage film, poor contact between the two films, and air in the middle of the film. In the case of being interposed, there is a problem that the loss of ultrasonic energy increases and the amount of fog generated decreases.

As described above, when an ultrasonic wave passage film is used, there is an energy loss regardless of the number of the films, and thus it is a problem to secure a fog generation amount.

Even when the water is simply atomized without using the ultrasonic wave passage film, a large amount of fog may be generated depending on the application. For example, the mist is used for stage production. For this purpose, Japanese Patent Application No. 2004-320631 includes a device that arranges a plurality of ultrasonic transducers in water and atomizes them, collects the fog in one tube, and discharges it from the tube using a blower. It is disclosed.

However, in an apparatus in which ultrasonic transducers are simply arranged, there is a problem that the apparatus becomes large because the atomization tank needs to be widened. Further, with regard to the release of mist, it is difficult to produce the appearance of the mist beautifully with an apparatus that simply generates and transports an airflow with an impeller. Moreover, the apparatus which attaches a fragrance to fog, producing the discharge | release of fog is not implement | achieved.

By organizing the above, an ultrasonic fog generator that is compact, can generate a large amount of mist beautifully, can atomize fragrance-containing liquid, or can contain fragrance in the mist, is easy to clean, and has good maintainability. Not done.

JP 2003-245580 A Actual climbing 3100873 JP 3-65264 A Japanese Patent No. 3547132 Japanese Patent Application No. 2006-220886 Japanese Patent Application No. 2004-320631

The rectifying mechanism can have a honeycomb structure as shown in FIG. The chemical substance accumulation mechanism can be configured by occluding a chemical substance (Gb) in a net-like structure provided with air holes or a honeycomb structure member.

As the chemical substance, a liquid, a gel, a gel, or a solid can be used.

<Means 6>

A plurality of ultrasonic transducers (40) provided around the central axis (CT), A submerged pipe (30) for guiding ultrasonic waves generated from the vibrator from the liquid to the outside of the liquid, and a mist carrying cylinder (81 for discharging the scattered liquid discharged from the plurality of submerged pipes in a predetermined direction. ) Or mist transport pipe (27), and each submerged pipe (30) is arranged around the central axis (CT), and an arrangement circle (CirU) of the upper end (Up) of each submerged pipe Is smaller than the arrangement circle (CirL) of the lower end (Lw), that is, the upper end is provided to be inclined inward from the lower end, and the upper end is provided to be inclined in the peripheral direction, and the scattered liquid is It is set so as to be concentrated in the central axis direction .

<Effects of Means 1>
As shown in FIGS. 1 to 6, in the present invention, an ultrasonic generator (05) having a plurality of vibration surfaces (40F) around a central axis (CT) is used, and an ultrasonic reflector (25) is provided around the ultrasonic generator (05). If the angle is adjusted by providing 26), the liquid in a predetermined region can be efficiently atomized, and a large amount of fog can be generated . Further, since the liquid scattering range is small, the apparatus can be configured in a small size . By changing the number of movements of the plurality of vibration surfaces, the amount of generated mist can be changed stepwise .

In the present invention, it is difficult to concentrate a plurality of ultrasonic waves on a predetermined region of the liquid unless the positional relationship between the plurality of vibration surfaces and the reflector is accurately adjusted. Adjustment is unnecessary by manufacturing the member to be attached and the plurality of ultrasonic reflectors by integral molding (TOM). The adjustment problem is solved by screwing the ultrasonic vibrator onto the mounting member or by inserting and fixing the ultrasonic vibrator. It is inexpensive if manufactured by integral molding using a mold .

In the present invention, since a large amount of liquid moves and scatters, waves are likely to be generated on the liquid surface near the liquid column. If the liquid level is not stable, the atomization efficiency may decrease. Therefore, when the submerged pipe (30) is attached so as to surround the liquid column (AK1) as shown in FIGS. 2 (D), 3, 4, and 5, generation of waves can be suppressed. The diffusion of ultrasonic waves inside can be prevented. For this reason, the atomization efficiency is improved. When the tip of each submerged tube is set to face inward, the scattered liquid or mist can be guided to the mist transport cylinder (81) or the mist transport tube (27). A large amount of fog can be generated and released in a small space .

<Effects of Means 2>
As shown in FIGS. 1 to 6, the ultrasonic waves (US) reflected by the plurality of reflectors (25 or 26) are set so as to concentrate on a predetermined area of the liquid, and the liquid scattered in the predetermined area. Is guided to the mist transport cylinder (81) or the mist transport pipe (27) and released to the outside, so that the liquid does not scatter widely as in the prior art. Since the range in which the liquid scatters is limited, the apparatus can be reduced in size .

In particular, when a concave mirror lens is used for the reflecting plate, the range in which the liquid scatters is extremely limited as shown by AK1C in FIGS. 1, 2, and 5, so that the apparatus can be further miniaturized .

In addition, since scattered ultrasonic waves with strong directivity are emitted into the air when the liquid is scattered, if the ultrasonic waves are guided to a tube having a predetermined thickness with a hard material, an ultrasonic traveling wave is generated.

The ultrasonic wave travels toward the tip while reflecting inside the tube. At this time, the generated mist is pushed up (conveyed) to the tip of the tube and released. In addition, a part of the liquid drop in the tube is atomized by the ultrasonic waves.

As shown in FIGS. 5 and 6, when the ultrasonic traveling wave tube (27) is used , the mist can be released to the outside without using the airflow generation mechanism, the amount of mist can be increased, and the liquid scattering range can be increased. Since it is narrow, it is effective for reducing the size of the apparatus .

When air is sent from the lower part of the mist carrying cylinder (81) or the mist carrying pipe (27), the mist can be carried away. In the present invention, since a large amount of mist is generated, it is possible to produce a mist by controlling the amount of blown air .

In particular, as shown in FIG. 1, when an air cannon (74) is used, an annular fog (Lm) can be made to fly far. The production effect is high because creating a large foggy ring in the air attracts people's eyes . Also, if you add a scent to the mist, it becomes a scented ball. You can pinpoint scents to remote users .

<Effects of means 3>
As shown in FIGS. 1, 2, 3, and 6, the ultrasonic wave (US) passes through the ultrasonic wave propagation medium (Liq 1) and the ultrasonic wave passage films (24, 23), and the liquid to be atomized (Liq 2). ), A small amount of special liquid can be atomized . The liquid can contain high-grade fragrances, pharmaceuticals, bactericides, deodorants, insecticides and the like.

By using two or more ultrasonic wave passage films, the atomization target liquid (Liq2) can be easily separated from the ultrasonic wave propagation medium (Liq1). When atomizing (in use), ultrasonic waves easily pass from the ultrasonic wave propagation medium to the atomization target liquid, and when not in use, separate the container (20) containing the atomization target liquid and place it elsewhere. Can be stored. Handling of atomized liquid of interest is extremely easy.

Further, as shown in FIGS. 1, 2, and 3, the ultrasonic wave propagation medium (Liq1) does not come into contact with the outside air, and therefore is not easily deteriorated. Therefore, the ultrasonic transducer (40), the ultrasonic propagation medium (Liq1), and the first ultrasonic transmission film (24) can be unitized. Conventionally, the cleaning of the vibration surface of the ultrasonic vibrator has been a troublesome work, but the cleaning of the vibration surface becomes almost unnecessary by unitization. Moreover, since the 1st ultrasonic wave passage film (24) is exposed to the upper part of a unit, it is easy to clean. That is, maintenance is very easy .

In general, there is a concern about loss of ultrasonic energy when a plurality of ultrasonic passage films are used. However, in the present invention, ultrasonic waves generated from an ultrasonic generator (05) having a plurality of vibration surfaces (40F) are applied to a predetermined region. In other words, the liquid can be sufficiently atomized even when there are a plurality of ultrasonic passage films. A large amount of fog containing chemicals such as fragrances and pharmaceuticals can be generated .

<Effects of Mean 4>
Conventionally, since only one surface of one ultrasonic transducer has been used in contact with the liquid, the efficiency is poor, but in the present invention, as shown in FIGS. 1, 3, and 6, the ultrasonic transducer (40) The liquid is atomized by bringing both surfaces of the liquid crystal into contact with the liquid and reflecting the ultrasonic waves from the both surfaces in the same direction with the two reflecting plates (25-1, 25-2, or 26-1, 26-2). As a result, the atomization efficiency is improved. Moreover, it can comprise in a small size .

<Effects of Means 5>
As shown in FIGS. 1, 2, and 4, the mist generation apparatus can generate a large amount of mist, so that the mist passes through the vicinity of the mechanism (12) where chemical substances are accumulated. The vaporized chemical substance dissolves in the mist and is released as a chemical substance-containing mist . Since the range in which chemical substances scatter is extremely limited, cleaning is easy and maintenance is good . In addition, since the structure is simple, the apparatus can be made compact .

In particular, when a rectifying mechanism is used for the chemical substance containing mechanism (12), the flow of mist is constant, so that the mist is likely to be released in a predetermined direction. When the chemical substance-containing mist is released , the chemical substance is released in the intended direction, so there is little waste and efficiency is high . Moreover, since the mist is discharged straight from the tube or tube, it is beautiful and has a healing effect .

That is, when the mist is disturbed and released, there is a problem that the chemical substance is discharged wastefully and the efficiency is not good, and it is not aesthetic, but by using the rectifying mechanism and the chemical substance accumulation mechanism of the present invention, The problem is solved.

As shown in FIG. 4, by using the heating means (HT1), the vaporization of the chemical substance is promoted, so that the concentration of the chemical substance contained in the mist can be increased. Moreover, the concentration of the chemical substance can be controlled by controlling the temperature (Con2).

<Effects of Means 6>
In the present invention, since a plurality of vibration surfaces are used, waves are likely to be generated near the liquid surface where the liquid column is generated. If the liquid level is not stable, the atomization efficiency may decrease. Therefore, when the submerged tube (30) is attached so as to surround the liquid column (AK1) as shown in FIGS. 4 and 5, the generation of waves can be suppressed, and the diffusion of ultrasonic waves in the liquid can be prevented. . Therefore, atomization efficiency is improved.

Furthermore, each submerged tube (30) is arranged around the central axis (CT), and the upper end of each submerged tube is inclined inward from the lower end, and the upper end is inclined in the circumferential direction. Since it is provided (FIGS. 4C and 5B), the scattered liquid concentrates in the central axis direction. Therefore, the scattered liquid or mist can be efficiently guided to the mist transport cylinder (81) or the mist transport pipe (27). A large amount of fog can be generated and released in a small space .

In particular, as shown in FIG. 5, when the ultrasonic wave is focused using the concave mirror lens (25) and the liquid is atomized locally, an ultrasonic traveling wave is generated in the mist carrying tube (27). , without using the air flow generating means, it can release fog.

FIG. 1 shows a first embodiment of the present invention, in which a perfume-containing liquid Liq2 in a small liquid container 20 is atomized using an ultrasonic generator 05 having a plurality of vibration surfaces and a concave mirror lens 25, and an air cannon 74 is used. This is a mist generator that emits mist. (A) is a longitudinal sectional view of the present apparatus.

In the figure, reference numeral 06 denotes a lower housing. The internal configuration will be described. Reference numeral 40 denotes an ultrasonic vibrator, and the left and right surfaces are vibration surfaces 40F. Ultrasound is emitted on both sides. CT is the central axis of the two vibration surfaces. Ultrasound is indicated by a thick solid line US. Reference numeral 41 denotes a mechanism for holding the vibrator 40, and a drive circuit can be provided therein. Con1 is a device that controls the operation output, operation interval, timing, and the like of the ultrasonic transducer 40.

Reference numeral 40 denotes a circular plate which is driven at a high frequency of 1 MHz or more and can generate a mist having a diameter of 10 microns or less. Specifically, when driven at 2.4 MHz, a large amount of fog having a diameter of about 3 microns can be generated. When it comes to such a fine particle, it is dry and there is no stickiness when touching the skin. If the vibrator can be manufactured thinly, it can be driven at a higher frequency.

Concave mirror lenses 25-1 and 25-2, which are ultrasonic reflectors, are provided to face 40F. The ultrasonic waves are reflected by the reflecting plate and travel toward the upper local region AK1C.

41, 25-1, and 25-2 can be integrally formed of plastic, metal, or the like. The hatched portion TOM indicates a state in which it is integrally molded using a mold. In the present invention, it is difficult to adjust the position and angle of the ultrasonic transducer and the reflecting plate in order to guide the ultrasonic wave to a predetermined region. However, adjustment is unnecessary by integrally molding. The ultrasonic transducer 40 can be attached to 41 by means such as screwing or insertion.

Reference numeral 19 denotes a container for containing a liquid so as to fill the vibration surface 40F, and a part of the container constitutes the concave mirror lens 25 as described above. 19 includes water W as the ultrasonic propagation medium Liq1. As Liq1, in addition to water, alcohol, oil, liquid resin, silicon resin, or the like can be applied. High thermal conductivity is desirable.

At the top of 19, an ultrasonic wave passing film 24 is provided at the interface of Liq 1. Reference numeral 24 denotes a first film through which reflected ultrasonic waves pass. For 24, a substance having an acoustic impedance close to that of Lig1 is desirable to avoid attenuation of ultrasonic waves. Silicone rubber, vinyl chloride, soft acrylic, and other soft material thin films can be used. Since the ultrasonic wave passing film may become a high temperature due to focusing of the ultrasonic wave, a film having high thermal conductivity is desirable.

A second ultrasonic wave passage film 23 is provided at the bottom of the small container 20 into which the atomization target liquid Liq2 is placed. It is desirable that the membrane has an acoustic impedance close to that of the liquid. However, if the membrane is thin, the acoustic impedance of the material does not match and can be used. For example, a hard material thin film such as stainless steel, titanium alloy, glass, noble metal alloy, or resin can be used.

As a result of experiments, a thickness of 0.2 mm or less is suitable for the ultrasonic passage film, and a thickness of 0.5 mm or less is suitable for a resin or rubber having a low hardness.

Further, it is desirable that the bottom portion of 23 has an arch shape as shown in FIG. When 23 is made into an arch shape, when it is pressed against 24, the stress is dispersed in the film surface direction, so that deformation hardly occurs. Even if a thin film is used, it can be pressed strongly.

Reference numeral 203 denotes a part of a mechanism that holds 20 in a detachable manner. 20 can be separated from the lower housing 06 by lifting.

If 23 cannot be strongly pressed against 24, air may enter between them. When air enters, since the acoustic propagation impedance differs, the loss of ultrasonic energy increases. Therefore, an ultrasonic propagation medium Liq3 may be provided between 23 and 24. Although water W is used for Liq3 in the same figure, oil, liquid resin, etc. can be used besides water. Of course, Liq3 can be omitted when the adhesion between 23 and 24 is good.

Although the case where 24 is soft and 23 is hard is shown as the ultrasonic wave passing film, a flat film in which both are soft may be used. Also, 24 may be omitted and only 23 may be used.

As the liquid to be atomized Liq2 to be put in 20, water W, fragrance-containing water Wa, liquid medicine, alcoholic beverage, alcohol, bactericidal liquid, deodorant liquid, liquid insecticide, and other chemical substance-containing liquids Applicable.

For example, when Liq2 is a liquid that has an effect on beauty and health, such as mineral water, antibacterial agent-containing water, or pure water, and the fragrance-containing mechanism 12 described later contains forest-based fragrance in the mist, The effect similar to is obtained.

The ultrasonic wave US is focused near the liquid surface of Liq2, and the liquid is locally scattered. AK1 indicates a liquid column rising from the liquid surface, and AK1C indicates a liquid scattering portion. A large amount of mist is generated when the liquid splashes. In addition, the ultrasonic waves are violently reflected at the liquid interface and scattered around. The directivity of the scattered ultrasonic waves is strong, and mainly scatters upward.

Next, the fog release mechanism 04 provided in the upper part is demonstrated. In this embodiment, the reference numeral 04 includes a mist transport pipe 27, an atmospheric pressure generation container 28, and a mist discharge cylinder 80. The lower part of 27 is expanded to take in the scattered liquid AK1. 27 is attached to 28, and the lower part of 28 is attached so as to cover the housing 06.

The operation will be described. The mist ma generated in AK1C, the droplet liquid AK2, and the scattered ultrasonic waves are emitted to the lower end of 27. Since the ultrasonic wave has a strong directivity, it travels upward while reflecting inside 27 as shown in FIG. That is, an ultrasonic traveling wave is generated in the tube. The thickness of the tube is preferably 20 mm or less, but may be any shape that produces a traveling wave even if it is 20 mm or more.

The fog ma is pushed up by the traveling wave and emitted from the tube tip. A part of the droplet-like scattered liquid AK2 in the tube is continuously atomized by the ultrasonic traveling wave. Therefore, a large amount of fog is generated. Although FIG. 1A shows an example in which the airflow generation means 74 is used in combination, fog can be emitted without using the airflow generation means.

12 is a mechanism for accumulating perfume and adjusting the flow of gas, and is configured by a set of small-diameter air tubes AirP. Fragrance is accumulated in a part of the AirP. In the same figure, the state which accumulate | stored the gel-like fragrance | flavor Ga is shown. When the mist passes through AirP, the flow is adjusted and the vaporized fragrance is taken in. If a large amount of mist is allowed to pass through AirP, it may become clogged due to a supersaturated state, so that the surroundings can be heated. This will be described in detail later with reference to FIG.

In FIG. 1 (A), since water Wa containing the fragrance | flavor a is atomized and the said fragrance | flavor containing mist ma is passed through 12, the mist mab containing the fragrance | flavor a and b is shown from the upper part of 12 Is released. Further, pure water or natural water can be put into 20 and the fragrance b can be contained at 12. In this case, the fragrance-containing mist mb is released. That is, in this embodiment, one kind of fragrance can be mixed, or a plurality of fragrances can be mixed and mixed.

Reference numeral 80 denotes a cylinder for releasing the mist, and is fitted to the 27 so as to be freely rotatable. By rotating the tip of 80, the direction of mist emission can be changed.

Next, the airflow generation means that makes the mist fly beautifully far will be described. 74 is an air gun type airflow generating means, 75 is an air compression film, and 77 is a drive device for pushing 75 out. Move shows how 75 operates. Con3 is 74 control devices. Below 74, an air hole Air and an air hole opening / closing mechanism AirST are provided.

The operation will be described. When the air pressure in 28, 27 and 80 is increased by driving 74, the mist ma in 27 is released from the tip of 80, but when the pressure is instantaneously high, it becomes an annular mist Lm at the tip. In particular, when the tip of 80 is thinner than the abdomen, a beautiful annular mist is generated. It is desirable to set α in the range of 20 degrees to 80 degrees in the tip angle. Since Lm advances while making a vortex in the direction of travel, it can fly several meters to break its shape. An air flow in the apparatus is indicated by a one-dot chain line Fg.

Regarding the control of the air cannon 74, the air compression membrane 75 is moved instantaneously, the inside of the cylinder (27 or 80) is pressurized, the film is held in that position until the air leaves the cylinder, and then You may control to return slowly. The device for driving the air compression film in this case can be constituted by a servo motor, a cam mechanism, a link mechanism, or the like. This control makes it possible to create a beautiful annular mist and fly straight from the gun barrel 80.

If a large one is used for 80, it is possible to fly over a distance exceeding 10 m. The appearance of a large mist ring containing scents is strange and interesting. When used in movie theaters and event venues, the production effect is high.

In order to make a beautiful scented ball, it is desirable to activate the air cannon 74 after 27 or 80 has sufficiently accumulated mist. A method for measuring the amount of fog in the upper part of 27 will be described. 47 is an LED, and 48 is a phototransistor, both of which constitute a photocoupler. As the amount of fog increases, the amount of light from 47 to 48 decreases, so the phototransistor current also decreases. The amount of fog can be estimated from the 48 current values.

The function of AirST will be described. In a state where AirST is closed, there is no path for generating an air flow in 28 and 27, so that fog is not emitted even when the ultrasonic transducer 40 is operating. The fog stays at the bottom of the tube. When AirST is opened, an air passage is created. Therefore, when the vibrator 40 is operated, an air flow is generated along the path Fg. The mist fills 27, 80 and is gently emitted from the tip. When the air cannon is operated, it is released far away as described above. Thus, various fog discharges can be performed by opening and closing the AirST and the operation of the air cannon.

Con3 may control the operation output, operation interval, timing, and the like of the air cannon 74. Further, the AirST can be provided with a drive control device Con4 not shown in the figure.

When these control devices are linked, a more beautiful annular mist can be created. For example, with the AirST opened, the ultrasonic transducer 40 is operated, the mist is guided into 27 and 80, and when sufficient mist has accumulated in the cylinder, 40 is stopped, and the AirST is closed, When the air gun 74 is operated, the mist accumulated in the cylinder can be reliably discharged.

Next, the advantage of using both sides of one ultrasonic transducer will be described. As shown in FIG. 1A, the distance between the two vibration surfaces 40F is extremely small. Therefore, the interval between the ultrasonic reflectors 25-1 and 25-2 can be reduced. The ultrasonic wave reflected at 25 travels at an acute angle toward AK1C. For this reason, when the liquid is scattered by AK1C, a scattered ultrasonic wave having strong directivity is generated upward. When the scattered ultrasonic waves are guided to the fog transport tube 27, a strong traveling wave is generated. The mist can be discharged efficiently even if the airflow generation means is omitted. That is, it is possible to achieve downsizing, economy, fog generation and emission efficiency of the apparatus.

Although not shown in the figure, two ultrasonic transducers may be overlapped and only one vibration surface may be used. In this case, the container in which the ultrasonic propagation medium Liq1 is placed is slightly larger than that in FIG.

FIG. 1B shows a configuration in which four ultrasonic transducers 40 are used as an alternative to the ultrasonic generator 05 of FIG. The side surface of the quadrangular prism is the vibration surface 40F. 41 has a built-in drive circuit. Around the 05, four concave mirror lenses 25 are provided to face the vibration surface. FIG. 1C is a top view of FIG.

In FIGS. 1B and 1C, the ultrasonic waves US emitted from the four vibration surfaces are converged and reflected by the concave mirror lens 25 and travel toward the upper side of the central axis CT of the four vibration surfaces. When four ultrasonic transducers are used, a large amount of fog can be generated. Since the fog is focused around the CT and guided to the fog transport tube 27, the apparatus can be configured in a small size.

FIG. 2 shows a second embodiment of the present invention in which the fragrance-containing liquid Liq2 in the small liquid container 20 is atomized using an ultrasonic generator 05 having eight vibration surfaces and eight concave mirror lenses 25, This is a mist generating device that emits a large amount of mist using the vehicle airflow generation means 70. 1A is a longitudinal sectional view of the apparatus, FIG. 2B is a top view of 05 and 25, and FIG. 2C is a view showing a half of the top view of the fragrance accumulation and gas rectifying mechanism 12. FIG.

The description will focus on the differences from FIG. In FIG. 2B, the vibrator holding mechanism 41 forms an octagon. An ultrasonic transducer 40 is attached around the central axis CT. In FIG. 1 (A), the ultrasonic wave US emitted from 40 is reflected by 25, converged in the vicinity of the liquid surface Suf of 20, and the liquid Liq2 is scattered to generate a large amount of fog. The scattered liquid and mist are guided to 27. The mist is transported upward and the large drop of liquid falls. AK3 is a scattered liquid that hangs down 27 walls.

The airflow generation mechanism 70 for releasing the mist is composed of blades 71 and a motor 72. When an air flow as indicated by Fg is generated, the mist is discharged from the tip of the transport tube 27.

12 has a honeycomb structure, and gelled fragrance Gb is accumulated in some holes. Since the gas is rectified by the cylindrical air hole AirP, the mist rises straight and quietly. This appearance is aesthetic.

In this embodiment, since many ultrasonic vibrators are used, a large liquid column AK1 is generated on the liquid level Suf of the 20 liquids to be atomized Liq2. In addition, there is a liquid falling from the wall surface 27, and a wave is generated in the Suf. If the influence of this wave is great, atomization may not be stable. The submerged tube 30 in FIG. 2D is for eliminating this wave, enhancing the focusing of the ultrasonic wave, and increasing the atomization efficiency. Can be attached as needed.

FIG. 3 shows a third embodiment of the present invention in which the fragrance-containing liquid Liq2 in the small liquid container 20 is fogged using the vibration surfaces 40F on both sides of one ultrasonic transducer 40 and the two flat reflectors 26. This is a mist generator that emits mist using vane-type airflow generating means 70. 2A is a longitudinal sectional view of the apparatus, and FIG. 2B is a top view of the ultrasonic generator 05 and the reflector 26. The difference from FIGS. 1 and 2 will be mainly described.

In FIG. 3A, the vibrator holding mechanism 41 and the flat reflectors 26-1 and 26-2 are integrally formed components TOM. The said structure is hold | maintained via the mechanism which has the air hole Air in the lower housing | casing 06. FIG. Reference numeral 28 denotes a pressure generating container for sending air to the lower part of the fog discharge cylinder 81. A blade-type airflow generation means 70 is provided at the bottom of 06.

On the ultrasonic wave passage film 24, a small liquid container 20 provided with an ultrasonic wave passage film 23 at the bottom is provided. Inside the 20, two submerged tubes 30 are provided. 31 is a holding mechanism for fixing 30 to 20. A fog transport cylinder 81 is attached on the top 20. An air passage hole Air is provided in the lower wall of 81. 20, 30, 31, 81 are integrated to form a mist release mechanism 04. 04 is detachably held in the lower housing 06. 203 is a part of the desorption mechanism. 04 is removed from the housing 06 when lifted.

The operation will be described. The ultrasonic wave US emitted from the ultrasonic wave generator 05 having the two vibration surfaces 40F is reflected by 26-1 and 26-2 and travels upward.

Here, as shown in FIG. 3A, 26-1 and 26-2 indicate that two ultrasonic waves travel inwardly as shown in FIG. 3A, and as shown in FIG. The angle is adjusted so as to pass each other so that the sound waves do not collide at the top. The rotation arrow Ke in (B) indicates the rotation direction of the reflector. That is, the right side of the reflecting plate 26-1 rotates in the direction perpendicular to the paper surface, and the upper side rotates in the direction perpendicular to the paper surface. 26-2 is rotating symmetrically.

In FIG. 3A, the US passes through the ultrasonic passage films 24 and 23 and proceeds toward the liquid surface of the atomization target liquid Liq2. The liquid level is pushed up, and a long liquid column AK1 is generated at two locations. At the tip of each liquid column, the ultrasonic waves are repeatedly violently reflected, and the liquid is scattered to generate a large amount of fog.

As shown by thick solid arrows in FIG. 3 (B), the US reflected by 26-1 and 26-2 have different directions, so that the scattered liquid AK2 and mist ma that come out of the two liquid columns do not collide. A large amount of fog can be generated by effectively using a narrow space.

In FIG. 3A, the submerged tube 30 has a lower end in Liq2 and an upper end in the air. No. 30 is for preventing the influence of the Liq2 wave, and for focusing the ultrasonic wave in the liquid, whereby the atomization is promoted.

In the present embodiment, a large amount of fog generated in a narrow space is guided to the fog transport cylinder 81. When a rising airflow is created in 81 by 70, the fog is discharged to the outside. The device can be made compact.

FIG. 4 shows a fourth embodiment of the present invention, in which a mist is generated using an ultrasonic generator 05 having four vibration surfaces 40F around a central axis CT, a flat reflector 26 and a submerged tube 30. This is a mist generating device that passes the fragrance accumulating mechanism 12 to contain the fragrance in the mist and discharges the mist using the blade-type airflow generator 70. 2A is a longitudinal sectional view of the apparatus, and FIG. 2B is a top view of the ultrasonic generator 05, the reflector 26, and the submerged tube 30. FIG. The difference from FIG. 3 will be mainly described.

In FIG. 4A, the four ultrasonic transducers 40 are attached to a rectangular columnar holding mechanism 41. In the liquid container 19, water W that is an atomization target liquid is stored. There is no ultrasonic passage film, and an air passage hole Air and a submerged tube 30 are provided in the lower part of the mist carrying cylinder 81. The lower end Lw of 30 is in the liquid, and the upper end Up is in the air.

There are four sub-tubes 30 which are inclined inward (tips in the CT direction). Therefore, as shown in FIG. 4B, the arrangement circle CirU formed by the four 30 upper ends Up is smaller than the arrangement circle CirL formed by the lower end Lw. Further, the upper end Up is inclined in the arrangement circumferential direction. As a result, as shown in the figure, the liquid and mist scattered from the upper end Up of 30 rarely collide with each other even in a narrow region. Since a large amount of mist m is generated around the central axis CT of the four vibration surfaces 40F, the mist can be guided to the mist transport cylinder 81 having an appropriate diameter.

Since air is sent to the lower end of 81 by the airflow generation device 70, the mist m is conveyed above 81. A perfume accumulation / gas rectification mechanism 12 is provided at the top of 81. Below 12, heating means HT 1 having a large number of cylindrical air holes AirP is provided. NC is a heating element such as a nichrome wire provided in a part of the air hole. The inside of the cylinder 81 and the gel-like fragrance Gb are warmed by the HT1. The fragrance vaporizes and fills AirP. In addition, liquid fragrance | flavor and gel fragrance | flavor can be used instead of Gb.

The mist m rising in 81 is warmed when passing through the AirP of HT1 and takes in the fragrance b when passing through the AirP of 12 to become a fragrance-containing mist mb and is released through the route of Fg. The heating means is controlled by the control device Con2.

Thus, since fog can be generated locally and guided to the cylinder, it is easy to cope with warming the fog, containing a fragrance, and releasing it. Also, the device can be made compact. This is an effect of a special configuration of the vibration surface, the reflector, and the submerged tube.

In the present embodiment, the ultrasonic transducer holding mechanism 41 may not be a regular quadrangular prism. The holding mechanism shown in FIG. 4C has a quadrangular pyramid shape. The vibrating surface 40F faces slightly upward. By doing in this way, the space | interval of the four reflecting plates which oppose a vibration surface can be narrowed. Moreover, the incident angle of the ultrasonic wave entering the reflector can be made an obtuse angle. The atomization efficiency can be increased with a small size. Moreover, cleaning is easy.

The present embodiment is characterized in that the ultrasonic transducer 40, the reflecting plate 26, and the submerged tube 30 are arranged so that the plurality of liquid columns AK1 do not collide, but this idea uses a reflecting plate. It can be extended even if not. That is, by arranging a plurality of ultrasonic transducers in a circular shape below the liquid tank and adjusting the installation angle of each transducer, a liquid column as shown in FIG. 4B can be generated.

That is, it can be realized by inclining the direction of the ultrasonic wave emitted from the vibrator in the direction of the central axis of the arrangement circle and further inclining in the circumferential direction of the arrangement circle. In this case, the submerged tube may be installed in the direction of ultrasonic waves. Thus, in the case of a flat reflector, it can be omitted, but the use of a reflector is more effective for miniaturization of the apparatus.

FIG. 5 shows a fifth embodiment of the present invention, which is a fog generating device that uses the concave mirror lens 25 in place of the flat reflector in FIG. 1A is a longitudinal sectional view of the apparatus, and FIG. 1B is a top view of the ultrasonic generator 05, the reflecting plate 25, and the submerged tube 30. FIG. The perfume containing mechanism 12 is omitted.

Four sets of the vibrating surface 40F and the concave mirror lens 25 are used, and fog is generated at four locations on the liquid surface. The liquid column AK1 pushed up by ultrasonic waves is smaller than that in FIG. In addition, the direction of the liquid column AK1 is inclined in the circumferential direction of the upper end arrangement circle CirU of the submerged tube as in the case of FIG. AK1C indicates a range in which the liquid mainly scatters.

As described above, the invention is devised so that the scattering range of the liquid is narrow and the scattered liquids do not collide with each other. In addition, since the ultrasonic wave scattered when the liquid is scattered has directivity in the upward direction, a traveling wave can be generated in the fog transport tube 27. Fog can be released without using airflow generating means. Compared with FIG. 4, it can be configured more compactly. Moreover, the atomization efficiency can be increased.

FIG. 6 is a sixth embodiment of the present invention, using the vibration surfaces on both sides of one ultrasonic transducer 40 and the concave mirror lens 25 to atomize the fragrance-containing liquid Liq2 (Wa) in the small liquid container 20, This is a mist generating device that emits mist using the ultrasonic traveling wave tube 27 and the heating means HT2.

The small liquid container 20 into which the atomization target liquid Liq2 is placed and the mist transport pipe 27 are connected by a fitting mechanism or a screw mechanism. Usually, they are used in an integrated manner. Between 20 and 27, a hole for supplying the fragrance-containing liquid Wa to 20 is provided. 01 is a container for accumulating Wa.

Heating means HT2 is provided outside 27 to warm the cylinder. Ascending airflow is generated in the cylinder. The fog generated in the vicinity of AK1C is released by the ultrasonic traveling wave generated in 27 and the heat rising airflow. The fog rises gently from the fog discharge cylinder 80. The appearance is beautiful, reminiscent of incense smoke.
