Description

  The present invention relates to an electrostatic atomizer that outputs an ultrafine mist obtained by atomizing a liquid containing a functional component to the outside such as in the air, for example, the interior of a car or the refrigerator.

Conventionally, functional ingredients such as vitamins have been used in cosmetics and clothing, including health supplements and pharmaceuticals. The main method of use is to absorb directly into the human body.
In addition, volatile functional components are also used in home appliances for the purpose of anti-oxidation or antibacterial purposes, but non-volatile functional components may be used by dissolving them in fresh water or volatile solvent alcohol. It was difficult to arbitrarily release it into the air.

  As means for releasing these components into the air, for example, as an atomizing device built in an air purifier or a humidifier to atomize a liquid, an ultrasonic atomizing device that atomizes the liquid using ultrasonic waves is known. ing. In general, an ultrasonic atomizer includes a piezoelectric element as an ultrasonic wave generating unit that generates ultrasonic waves, and a non-volatile functional component-containing liquid to be atomized is generated by ultrasonic waves output from the ultrasonic wave generating unit. It can be released as mist. However, the mist generated by ultrasonic waves is so large that the particles can be visually observed, and excessive humidity or wetting may occur, causing corrosion or mold.

Further, as an atomizing device for atomizing a liquid, in addition to an ultrasonic atomizing device, as disclosed in Patent Document 1, a liquid is applied by applying a high voltage to a capillary electrode or a capillary electrode and a counter electrode. An electrostatic atomizer that atomizes the water is known.
As this type of electrostatic atomizer, for example, a high voltage that applies a high voltage between a container containing a liquid, a capillary (capillary tube) that draws the liquid from the container, and an electrode provided on the capillary and a ground electrode What has a power supply is known.

  As described above, in recent years, air conditioners and air purifiers use a filter to clean the air and provide a comfortable indoor environment for the occupants. Furthermore, in recent years, products that release mist from air conditioners and air purifiers and can be expected to control indoor humidity, deodorize, and disinfect bacteria have been sold.

In air conditioners, air purifiers, humidifiers, etc., negative ion generators that use corona discharge, humidifiers that evaporate water and release mist, and electrolysis are used to improve the indoor environment. Alkaline ion water mist is equipped as an attached function.
For example, an application electrode for applying a negative voltage to water contained in the water holding unit, a grounded counter electrode, and a needle-like atomizing portion at the tip of the counter electrode that is in contact with the water. Electrostatic atomization with a negative ion generation function comprising a water absorbing body that electrostatically atomizes water sucked up from the water holding part and an ionization needle that generates negative ions by corona discharge between the counter electrodes. An air cleaner provided with a device is known (for example, see Patent Document 2).

  By the way, in the electrostatic atomizer disclosed by patent document 1, the high voltage power supply was needed, the cost of the high voltage circuit etc. which generate | occur | produce a high voltage became high, and the handling was necessary. In addition, in the electrostatic atomizer, there are concerns such as the generation of a strange odor due to the generation of ozone, which increases the cost of the entire device including measures for solving these problems, and the size of the entire device. There was a concern that would become larger.

  In addition, like the negative ion generation technique disclosed in Patent Document 2, a commercially available nano-sized mist generator uses a typical corona discharge action, and thus generates a large amount of negative ions. Like the above, ozone is generated. The cause of this is that the tip of the mist release substrate is formed in a sharp pointed shape for the purpose of increasing the amount of negative ions generated, so that sufficient water is drawn up to the tip of the mist release substrate. Since a sufficient amount of mist cannot be obtained because the amount of water retained is small, an arbitrary amount of water cannot be released as mist.

  Moreover, as a means for releasing functional components that are commercially available into the air, vitamins other than volatile components can be cited as iontophoresis devices. However, in ultrasonic generators, mist particles are micron-sized. Because it is too large, it tends to form water droplets and condense, and some generators using negative ions have nano-sized mist particles, but substances such as ozone are released into a narrow space like a car interior. It is not preferable for health.

In view of this, the present invention is intended to improve the indoor environment, for example, the interior of a refrigerator, as well as the interior of a car, and an aqueous solution mixed with functional ingredients such as non-volatile vitamins and catechins. It is an object of the present invention to provide an electrostatic atomizer that discharges a large amount from the discharge pin member of the electrostatic atomizer as a size mist.
In addition, metallic nano colloids are blended into functional aqueous solutions, nano-sized ultra-fine mist is released in large quantities from the discharge pin member of the electrostatic atomizer, and deodorized, sterilized, preserved freshness, etc. Another object is to provide an electrostatic atomizer that exhibits the above effect.

  The discharge pin member of the present invention is formed by combining one or more of ceramic material, synthetic resin material, porous material of metal material, or fiber molded body. Moreover, what formed the ceramic material etc. as a rod-shaped body is mentioned. When the material forming the release pin material is a porous body, it is more convenient for the aqueous solution to pass through the use of a material having innumerable micropores than an aggregate of independent microbubbles. .

  The discharge pin member sucks up moisture in the water supply container, and is configured so that the mist is discharged at the tip. Due to the direct current power source that negatively charges the discharge pin member, a spontaneous discharge phenomenon occurs from the discharge pin member, and a large amount of functional components can be discharged into the air together with mist using the ionic wind.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing an embodiment of an electrostatic atomizer according to the present invention. 2 is a longitudinal sectional view of the electrostatic atomizer according to the present invention shown in FIG. As shown in the figure, an electrostatic atomizer 10 according to the present invention is formed by a plurality of water supply containers 11 containing a functional aqueous solution 16 containing a non-volatile functional component, and a plurality of protrusions around the water supply container 11, A discharge pin member 14 having a sucking characteristic, a water retaining material 15 for fixing the discharge pin member 14 to the periphery thereof, and a mounting base 19 connected to a DC power source 13 for negatively charging the discharge pin member 14 via the water retention material 15. Is provided in the lower portion, and the functional aqueous solution 16 is sucked up from the water supply container 11 and the nano-sized mist containing the functional component is discharged from the tip portion 14a of the discharge pin member 14 to the outside.
Further, in order to protect the discharge pin member 14, a cover member 12 is provided on the mounting base 19 so as to cover the discharge pin member 14. The cover member 12 has a hole having substantially the same diameter as the diameter of the water supply container 11 at the top thereof so that the water supply container 11 is positioned and installed at the center position of the water retention material 15.

  Moreover, the functional aqueous solution 16 containing a non-volatile functional component is filled in the water supply container 11, passes through the diaphragm 18 stretched on the lower surface of the water supply container 11, and is a porous water-retaining material 15 presenting on a flat plate. It flows out to the inside. That is, in use, when the water supply cap 17 that covers the diaphragm 18 of the water supply container 11 is removed and the diaphragm 18 is fitted to the center from above the cover member 12 so as to contact the water retention material 15, The functional aqueous solution 16 passes through the diaphragm 18 and permeates the entire water retaining material 15, is sucked up to the discharge pin member 14 by capillary action, and enters the air as nanomist from the tip portion 14 a of the negatively charged discharge pin member 14. Released.

  The water retaining material 15 and the discharge pin member 14 have an excellent water absorbing power and water retaining power, and are composed of one kind or two or more kinds of porous bodies or fiber molded bodies such as ceramic materials, synthetic resin materials, and metal materials. Are formed.

  The ceramic material constituting the water retaining material 15 of the porous body or the fiber molded body may be a single oxide such as silica, alumina, magnesia, titania, zirconia, or mullite, zeolite, bentonite, ceviolite, attapulgite, silimanite, kaolin. , Sericite, diatomaceous earth, feldspar, cocoon viscosity, silicate compounds (perlite, vanamicurite, sericite, etc.), natural fiber materials include pulp fiber, cotton, wool fiber, hemp fiber, etc. Examples of the resin material include polyester, nylon, rayon, urethane (including polyurethane), acrylic, and polypropylene, and examples of the metal material include stainless steel, copper, titanium, tin, platinum, gold, and silver.

  In addition to the shape of the porous body and the fiber molded body, a honeycomb structure and a corrugated structure are exemplified, and a pipe shape, a sheet shape, a pleat shape, and the like are also exemplified. The necessary condition is that it has excellent water absorption and water retention.

The mounting base 19 is fitted and fixed by fitting the water supply container 11, the cover member 12, the discharge pin 14 and the water retention material 15 together, and at the same time, via the water retention material 15 by connecting the negative electrode of the DC power source 13. The discharge pin 14 is negatively charged.
Moreover, the lamp | ramp 20 is arranged in the periphery of the mounting base 19 along the outer periphery of the cover member 12 at equal intervals, and it becomes easy to recognize the place by illuminating the water supply container 11 in dark places, such as a nighttime. At the same time, it can bring out a sense of quality and production effects.
The kind of the lamp 20 used is not limited, but it is preferable to use an LED lamp. This is because the LED lamp is small, strong against vibration and impact, and has a long life. Further, the emission color of the lamps arranged is not particularly limited, and those having a desired emission color such as white, amber, blue, and green can be employed. Each lamp may have the same emission color, and may include lamps of different emission colors.

  The DC power supply 13 is a power supply that generates a DC negative voltage of, for example, about 1 to 10 kV, and its negative electrode is connected to the mounting base 19 via a conductor, and the power supply is connected to the water retention material 15 through the mounting base 19. Thus, the water retaining material 15 that holds water or an aqueous solution containing a functional component is negatively charged. By connecting the negative electrode of the DC power supply 13 to the water retaining material 15 through the mounting base 19, the current flows in search of a place where discharge is most likely to occur, and usually gathers in a place where the tip is pointed or a place with excellent conductivity such as metal. The discharge pin member 14 is collected using the properties.

FIG. 3 is an explanatory diagram of a water supply container 11 that contains a functional aqueous solution containing a nonvolatile functional component. A diaphragm 18 is stretched on the bottom surface of the water supply container 11, and a water supply cap 17 is attached so as to cover the diaphragm 18 when not in use.
When the water supply container 11 is used, first, when the water supply cap 17 is removed from the water supply container 11 and placed in contact with the water retention material 15, the functional aqueous solution 16 filled in the water supply container 11 is stretched on the bottom surface of the water supply container 11. It flows out to the water retaining material 15 from the provided diaphragm 18. Since the functional aqueous solution 16 gradually passes through the diaphragm 18 and flows out to the water retaining material 15, it is possible to prevent excessive supply of the functional aqueous solution.
The method of attaching the water supply cap 17 to the water supply container 11 is not limited. For example, the water supply cap 17 is formed by forming a male screw part on the outer periphery of the water supply container 11 and forming a female screw part on the inner periphery of the water supply cap 17. It can be attached by an attachment method for attaching to the water supply container 11 as an outer lid, or an attachment method by a fitting structure of a cap and a main body formed by projections and depressions composed of projections and depressions.
Examples of the diaphragm 18 include a semipermeable membrane such as cellophane, which has low water permeability.

  Functional components of the functional aqueous solution 16 include vitamin C (L-ascorbic acid), vitamin C ester (such as L-magnesium phosphate phosphate, sodium L-ascorbate phosphate, magnesium ascorbate phosphate), vitamin A , Vitamin B, vitamin D, vitamin Dα-riboic acid, amino acids, tea extract (catechin, tannin, saponin, theanine, caffeine, etc.), hyaluronic acid, collagen, aroma essential oil (lavender, rosemary, lemongrass, tea tree, Organic soluble ingredients such as sage, clove, orange, grapefruit, cinnamon, jasmine), coffee beans, tea confectionery, wasabi, hinokitiol, chitin, chitosan, propolis, etc., and other inorganic substances (inorganic soluble ingredients) , Silver or Sodium chloride, and the like.

  Here, “functionality” means a property that makes the living environment comfortable and can improve health, deodorization (deodorization, decomposition, etc.), antimicrobial (antibacterial, bactericidal, bacteriostatic, antibacterial) Must have at least one type of properties such as mold, antiviral, etc., relaxation (aromatherapy), moisturizing, antioxidant, harmful organism repellent, antistatic, dustproof, etc. means.

FIG. 4 is a top view showing an arrangement state of the discharge pin member 14 provided in the electrostatic atomizer 10 of the embodiment shown in FIG. As shown in the figure, a plurality of discharge pin members 14 are arranged at equal intervals along the periphery of the water supply container 11.
Although the number of the discharge | release pin members arrange | positioned is not specifically limited, About 3-12 are preferable.

FIG. 5 is a schematic side view showing the tip shape of the discharge pin member 14, (a) is an enlarged view of a main part showing the discharge pin member having a substantially flat tip portion, and (b) is an elongated sharp shape. It is a principal part enlarged view which shows the discharge | release pin member which has a triangular pyramid-shaped front-end | tip part, (c) is a principal part enlarged view which shows the discharge | release pin member which has a triangular pyramid-shaped front-end | tip part, (d) is a round-shaped front-end | tip. It is a principal part enlarged view which shows the discharge | release pin member which has a part, (e) is a principal part enlarged view which shows the discharge | release pin member which has roundness and has an elongate front-end | tip part.
As shown in the drawing, the discharge pin member 14 is a member that is formed as a rod-like body (stick body) and discharges the functional aqueous solution 16 as a fine nanomist of about 1 to 100 nm, on one side (one side) of the water retention material 15. A plurality of (for example, about 3 to 12) protrusions are provided with the tips facing upward.
By forming the discharge pin member 14 as a rod-like body in this way, nano-sized mist is easily discharged from the discharge pin member 14, and a function is provided by providing a plurality of discharge pin members 14 on the water retaining material 15. It is possible to increase the release amount of nanomist containing a sex component.

The structure of the distal end portion 14a of the discharge pin member 14 is preferably a structure that is tapered more than the flat surface, but the distal end portion 14a does not need to be sharply pointed and may have a moderately rounded shape. .
Further, the cross-sectional shape of the distal end portion 14a of the discharge pin member 14 is rounder or oval (see FIGS. 5 (d) and 5 (e)) than the square shape with the edge (see FIG. 5 (a)). (That is, it is formed with a curved surface rather than an acute point), and by forming in this way, a large amount of functional components can be included in the released mist.
Further, the discharge pin member 14 is formed to have a diameter of several mm (for example, 2 to 3 mm) and a length of several tens of mm (for example, 30 mm).
Note that the amount of mist discharged differs depending on the length and diameter of the discharge pin member 14 and the number of the discharge pin members 14 and the shape of the distal end portion 14a.

Further, the rate at which the release pin member 14 can retain the functional aqueous solution is preferably about 30 to 150%, more preferably about 70% or more for the lower limit, and more preferably 110% or less for the upper limit.
The discharge pin member 14 preferably has a higher water absorption capacity than the water retention material 15. This is because the aqueous solution containing the functional component absorbed in the water retaining material 15 is efficiently sucked up and supplied to the discharge pin member 14 without staying in the water retaining material 15.

As the discharge pin member 14, ceramic fibers (ceramic fibers, glass fibers, etc.), organic fibers (polyester fibers, rayon fibers, nylon fibers, etc.), metal fibers (stainless fibers, copper fibers, titanium fibers, etc.) are formed as rods. The thing which was done is mentioned.
Other examples include porous bodies obtained by sintering ceramic particles and metal particles as rod-like bodies, and foams such as urethane resins and styrene resins formed as rod-like bodies. In the case of a porous body, it is convenient for the aqueous solution to pass through that the infinite number of micropores are continuous rather than an aggregate of independent microbubbles.

For porous structures such as ceramics, resins, metals, etc., the release performance is determined by the water absorption characteristics of water, and the amount of water taken up per hour is particularly important.
These performances are determined by the water absorption rate per hour of the porous body, and the water absorption rate of about 30 to 100% is suitable for any material. -80% is preferable, 70-110% is preferable for the resin, and 10-60% is preferable for the metal.

Furthermore, as shown in FIG. 6, there are various rod-shaped discharge pin members 14. For example, there is a porous body having continuous pores in which innumerable fine pores are continuous (see (a)).
Further, as a specific configuration when forming the release pin member 14 in a fiber molded body structure, in ceramics, a glass fiber called silica fiber or silica or mullite crystalline fiber molded using a binder or sintered The synthetic resin includes fibers such as polyester, nylon, and acrylic, and short fibers are knitted using binders or entangled with short fibers (see (b)) ).
In addition, long fibers are bundled (converged) so as to have an arbitrary thickness, and are cut by appropriate use (see longitudinal sectional view (c)).

In these fiber molded body structures, an aqueous solution containing a functional component can be sucked up from the water retaining material 15 by capillary action. However, when the diameter of the discharge pin member is thin, the movement of water is slow and the amount of mist released per hour is small. Therefore, it is necessary to adjust the diameter of the discharge pin as necessary.
In addition, the discharge pin member 14 can take various shapes such as a conical shape and a square injection shape other than the cylindrical shape.

  Here, the material of the discharge pin member 14 will be described. When the material of the discharge pin member 14 is compared between the polyester fiber and the porous ceramic, the polyester fiber and the porous ceramic exhibit higher sucking ability. This is because, in the case of polyester fibers, the porous matrix is in a mesh state in ceramics, compared to the case where all the fibers are bundled in the length direction. Can be mentioned.

However, when viewed as the humidifying capacity of the discharge pin member 14, even if the sucking capacity is small, moisture is evaporated from the entire discharge pin member 14, so that the significant difference from that of the polyester fiber is small in terms of the humidification amount. .
Since the polyester fiber is molded with the structure as described above, the amount of transpiration from the periphery of the discharge pin member is smaller than that of ceramics.

That is, polyester fiber is suitable for the case where deodorizing performance and sterilizing performance by nanomist are expected, and for the release of components such as vitamin C and catechin that are functional components that cannot be expected to volatilize.
Further, when the emphasis is placed on the humidifying power or the non-combustibility of the discharge pin member 14 is required, a porous ceramic material is suitable. If the porosity of the ceramic porous body is changed, the water retention rate can be controlled to some extent, but the water suction speed equivalent to that of the polyester fiber cannot be obtained.
In addition, when a large amount of water is expected, the strength of the porous body itself is lowered, and there is a tendency that the risk of being broken or broken due to vibration during assembly work or transportation is increased.

The electrostatic atomizer does not necessarily have a cylindrical shape. FIG. 7 is a schematic view showing another embodiment of the electrostatic atomizer according to the present invention. As shown in the figure, the electrostatic atomizer 10 that emits nano-sized mist has the same structure as the cylindrical electrostatic atomizer shown in FIG. 1 except that the shape thereof is a quadrangular prism.
The electrostatic atomizer of the present embodiment is a water supply container 11, a cover member 12, and a mounting base 19, all of which are square pillars, and the dimensions of the water supply container are 2 cm (vertical) × 2 cm (horizontal) × 5 cm (height) ) The size of the cover member 12 is about 4 cm (length) × 4 cm (width) × 3 cm (height), and the size of the mounting base 19 is 4 cm (length) × 4 cm (width) × 2 cm It is about the size of (height).
The electrostatic atomizer according to the present invention has an appropriate size so that it does not get in the way when installed indoors or in a vehicle.

  FIG. 8 is a top view showing an installation state of the discharge pin member 14 in the electrostatic atomizer according to the embodiment of FIG. 7. As shown in the figure, a plurality of discharge pin members 14 are arranged at equal intervals along the periphery of the water supply container.

  The functional aqueous solution 16 may be an aqueous solution containing metal nanocolloids in addition to the functional component. Here, the metal nanocolloid refers to platinum nanocolloid, gold nanocolloid, palladium nanocolloid, and the like. The aqueous solution concentration of the metal nanocolloid in the aqueous solution is preferably about 0.001% to 0.01%.

  Metal nano-colloid is a nanometer-sized platinum fine powder controlled in a colloidal state, and has an average particle diameter of about 1 to 100 nm of noble metal fine particles made of platinum, gold and palladium, and noble metal fine particles. It consists of a colloidal agent made of an organic material to be colloided.

  Examples of colloidal agents include thickeners, surfactants, carboxyl group-containing compounds that contain a carboxyl group in the chemical structure, polyacrylic acid (including salts such as Na and K), polymethacrylic acid (Na, K), polyacrylic acid ester, polymethacrylic acid ester, polyvinylpyrrolidone (especially poly-1-vinyl-2-pyrrolidone), polyvinyl alcohol, aminopectin, pectin, methylcellulose, methylsulose, glutathione, cyclo Dextrin, polycyclodextrin, dodecanethiol, organic acid (hydroxycarbanoic acid such as citric acid), glycerin fatty acid ester (polysorbate), cationic micelle-cetyltrimethylammonium bromide, surfactant (anionic, cationic) , Bisexual, nonionic) Alkyl alkali metal salt of sulfuric acid ester, mixtures thereof can be exemplified.

  When the colloidal agent is a carboxyl group-containing compound, it is desirable to contain the fine particles so that the number of moles of carboxyl groups is about 80 to 180 on the basis of the number of moles of platinum.

  The method of generating an aqueous solution containing metal nanocolloid as nanomist is performed using the electrostatic atomizer 10 configured as described above, and the metal nanocolloid is mixed together with a nonvolatile functional component from the water supply container 11. The negative electrode of the DC power supply 13 is connected to the discharge pin 14 holding the aqueous solution 16 via the mounting base 19 and is negatively charged.

  When the discharge pin 14 holding the aqueous solution 16 containing the non-volatile functional component is negatively charged in this way, a current flows to the tip portion 14a of the discharge pin member 14 to cause a spontaneous discharge phenomenon. An ionic wind is generated, and functional components such as water and vitamins can be released into the air as nano-sized (about 1 to 100 nm) invisible fine nanomist using the ionic wind.

Since the nano mist particles containing the functional component discharged from the discharge pin member 14 have a size of about 1 to 100 nm, the corners of the room are used by utilizing the wind of a blower fan such as an air conditioner or an air purifier. Can be scattered.
Further, the discharge pin member 14 is always in a sufficiently wet state, and as described above, the water retention amount of the porous material constituting the discharge pin member 14, the length and diameter of the discharge pin member 14, the shape of the tip portion 14a, Depending on the number or shape (bar shape, cylindrical shape, etc.), the ability to release water or a mist of a functional component varies.

As described above, the electrostatic atomizer according to the present invention is formed by protruding a discharge pin member having a suction property on a water retaining material, and a mounting base for mounting and fixing the water retaining material, and a mounting base. And a DC power source that is connected to the negative electrode and negatively charges the discharge pin member.
Since the discharge pin member does not have a positive counter electrode with respect to negative charge, a spontaneous discharge phenomenon occurs from the discharge pin member, and a large amount of nano-sized mist can be discharged using the wind.
Since no positive counter electrode is provided, it is not necessary to generate ozone at all in the mist to be emitted, and the functional component can be efficiently contained to make a mist.

  In addition, since the aqueous solution containing the non-volatile functional component is supported on the water retention material and the nano pin containing the non-volatile functional component is released from the release pin member, it can cope with environmental improvements in various atmospheres. . And deodorizing and disinfecting action can be obtained effectively.

  Also, the discharge pin member and the water retaining material are formed by combining one or more of ceramic material, synthetic resin material, porous material of metal material, or fiber molding, so that it has excellent suction power A pin member can be realized.

  In addition, since the release pin member has a rod shape, the nanomist containing the functional component is easily released, and by projecting a plurality of release pin members, the release amount of the nanomist containing the functional component can be increased. Can do.

  In addition, the non-volatile functional component supported by the water retaining material is an organic water-soluble component such as vitamins, vitamin derivatives, catechin, hyaluronic acid, amino acids, collagen, or an inorganic soluble component such as silver or salt. Since one or two or more of the components are combined, the supply amount or elution amount of the functional component to the release pin member and the suction speed can be controlled, and the release rate or release of the functional component The amount can be controlled and a long-term release life can be expected.

When the discharge pin member that holds water up to the tip is connected to the negative electrode of the DC power supply, a discharge phenomenon occurs between the water vapor in the atmosphere and OH radicals are generated, but ozone is not generated, and release The supply amount or elution amount of the functional component to the pin member and the suction speed can be controlled, and the release rate or release amount of the functional component can be controlled.
In addition, a mist having a smaller fine particle diameter contains more OH radicals, and thus has superior bromide-free, antibacterial and antifungal effects due to chemical reaction.
