Patent Document 1: JP-A-2009-255091

However, in the electrostatic atomizing apparatus having an atomization section for generating a mist by applying a conventional high voltage, in the constitution, the porous body constituting the tip of the discharge fin member is in contact with air to cause an oxidation reaction, whereby oxide is adhered and the porous body is clogged There was another problem. When the porous body is thus clogged, the transfer of water due to the capillary phenomenon is hindered and electrostatic atomization hardly occurs. Therefore, it is necessary to perform maintenance such as removing oxides or the like adhering to the tip of the discharge fin member, There was a need to apply a higher voltage than needed for the emission.

As a result, it has been found that a discharge pin member capable of releasing a large amount of mist without applying a higher voltage than necessary by supporting a carbon material on a discharge pin member, A mist generating member used in combination with a discharge pin member and a moisture holding member, and an electrostatic atomizing member using the same.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described by way of embodiments for carrying out the invention. However, the following examples do not limit the invention according to the claims, nor do the features described through the examples restrict the present invention.

The discharge pin member according to the present invention is composed of a porous body or a core of a fiber-formed body and a conductive graphite compounding material formed so as to surround the core, and the conductive graphite compounding material leaves the bottom edge of the discharge fin member, The center is removed.

The electrostatic atomizing apparatus according to the present invention atomizes the aqueous solution by applying a high voltage and emits it in a mist form. The electrostatic atomizer includes a water storage portion, a moisture holding member that keeps water absorbed from the water storage portion, a discharge pin member protruding from the water holding member to discharge the mist to the outside, Electrode.

Among them, the release pin member is protruded from the water retention member, and sucks up water (referred to as an aqueous solution together with water in this specification) containing the water or the functional ingredient held by the water retention member, And discharging the mist to the outside. Therefore, the release pin member needs to have a high moisture absorption capacity and a moisture retention capability. This is for efficiently discharging the mist by sucking the aqueous solution into the discharge pin member without staying in the moisture retaining member.

The discharge fin member is composed of a core portion made of a porous body or a fiber-formed body, and a conductive graphite compounding material formed to surround the core portion. The porous body or the fiber formed body is formed by combining one kind or two kinds or more of a ceramic material, a metal material, a synthetic resin material and a natural resin material.

A porous body refers to a material having innumerable pores in its interior, and it is preferable to use a porous body in which a number of micropores are continuous rather than an aggregate of independent micro-cells to suck up the aqueous solution. For example, there can be mentioned a porous body obtained by sintering ceramic particles or metal particles in the form of rods, or a foamed body such as urethane resin or styrene resin. A fiber-formed body refers to a material in which a plurality of fibrous materials are converged and partially or totally adhered to each other by self-welding or an adhesive or the like, and the mesh-like voids are formed as a flow path of an aqueous solution. For example, ceramic fibers (ceramic fiber, glass fiber, etc.), organic fibers (polyester fiber, rayon fiber and nylon fiber), metal fibers (stainless steel fiber, copper fiber and titanium fiber) And the like.

The ceramic material may be a single oxide such as silica, alumina, magnesia, titania or zirconia or a single oxide such as mullite, zeolite, bentonite, sepiolite, attapolite, silimanite, kaolin, cericite, diatomaceous earth, feldspar, , A silicate compound (perlite, vermiculite, cericite, etc.), or a combination comprising at least one of the foregoing, but is not limited thereto. Examples of the metal material include, but are not limited to, stainless steel, copper, titanium, tin, platinum, gold, and silver. The synthetic resin material includes, but is not limited to, polyester, nylon, rayon, urethane (including polyurethane), acryl, and polypropylene. Natural resin materials include, but are not limited to, pulp fibers, cotton fibers, wool fibers, hemp fibers and the like.

The fiber formed body is formed by bundling and fixing a plurality of hollow fibers. A hollow fiber is a fiber in the form of a straw having a cavity inside and is used in the same sense as a capillary, a capillary, or hollow fiber. The outer diameter of the hollow fiber is 0.2 mm or less, preferably 0.1 mm or less, and the inner diameter is preferably 10 占 퐉 or more and 50 占 퐉 or less.

The raw material used for the hollow fiber may be any of organic materials and inorganic materials as long as it can be processed into a hollow fiber. Examples thereof include polyamide-based materials such as Nylon 6 (registered trademark), Nylon 66 (registered trademark) and aromatic polyamide Various types of polyester-based fibers such as polyolefin-based fibers, such as polyethylene terephthalate, polybutylene terephthalate, polylactic acid, polyglycolic acid, and polycarbonate, various acrylic fibers such as polyacrylonitrile, Polyvinyl alcohol-based various fibers, polyvinylidene chloride-based various fibers, polyvinyl chloride-based fibers, polyurethane-based fibers, phenol-based fibers, polyvinylidene fluoride Fluorine-based fibers composed of polytetrafluoroethylene or the like, carbon-based fibers such as carbon nanotubes And oil.

The core may be a honeycomb structure, a corrugated structure, a pipe shape, a sheet shape, a pleated shape, or the like insofar as it has a structure having excellent water absorption ability and water retention ability, in addition to a porous body or a fiber formed body.

The shape of the discharge pin member is not limited to the shape of a rod having a circular cross section, but may be an elliptical columnar shape, a conical shape, a prismatic shape, or the like. It is also preferable that the distal end portion of the discharge fin member has a rounded surface shape that is rounder than a plane shape. This is because the current can not reach the tip of the discharge fin member evenly and the aqueous solution can not be sufficiently retained if the tip has a sharp pointed shape, so that it is also preferable that the tip end of the discharge fin member is appropriately rounded.

Since the water absorbing property of the aqueous solution differs depending on the material and the structure of the core part made of the porous material or the fiber formed body, the discharge performance of the porous material or the fiber formed article is determined by measuring the amount of sucking up the aqueous solution per hour. The discharge performance is determined by the water absorption rate per hour of the deep part, and the water absorption rate of any material is suitably about 30 to 100%. In particular, it is preferable that the ceramic material is 30 to 80% 10 to 60%, and in the case of a synthetic resin material and a natural resin material, 70 to 110% is preferable. The water absorption rate refers to the percentage of the total water content contained in the porous body or the fiber formed body in the water saturated state with respect to the mass of the porous body or the fiber formed body in the absolutely dry state.

A conductive graphite compound material is formed around the deep portion so as to surround the deep portion. The conductive graphite compounding material refers to a conductive material containing conductive graphite. The conductive graphite compounding material that is formed so as to surround the periphery of the core portion can be realized by a means for applying it as a paint.

In addition, the discharge fin member according to the present invention may have a through hole for absorbing an aqueous solution at its side in the lower part. By forming the through hole for absorbing the aqueous solution on the side surface at the lower part of the release pin member, the aqueous solution can be easily absorbed from the moisture retaining member to the deep part through the through hole.

The conductive graphite compounding material is applied to the releasing pin member main body in the following procedure. First, as the conductive graphite compounding material, three kinds of conductive graphite adjusting liquids are mixed with a graphite paste as a conductive material, a binder and a diluent as a surfactant . The graphite paste refers to a paste-like solution in which the conductive graphite particles are dispersed with EDTA as a protective film as a surfactant. As the binder, an acrylic emulsion can be mentioned. Examples of the surfactant include anionic, nonionic, and cationic surfactants.

The conductive graphite adjustment liquid prepared as described above is formed by spraying the periphery of the core portion or immersing the core portion for about one minute in the conductive graphite adjustment liquid. The release pin member having the conductive graphite formed around the core portion is dried at room temperature for about 1 hour and then dried in a drier set at 80 DEG C for 3 hours or more to obtain a release pin member. Here, since moisture is absorbed by the capillary phenomenon from the bottom portion of the discharge fin member protruding from the water retention member, the central portion of the bottom portion of the discharge fin member is removed while leaving the conductive graphite compound material of the bottom edge portion .

That is, the conductive graphite compound material is removed due to moisture absorption at the central portion of the bottom surface portion of the discharge pin member. In order to prevent the conductive graphite compound material formed around the deep portion of the discharge pin member from peeling off from the bottom surface, As shown in FIG.

In addition, since the conductive graphite compound material is formed at the edge portion of the bottom face portion, there is an effect that the conductivity of the moisture retaining member with the conductive layer is improved. The method for removing the conductive graphite compound material from the central portion of the bottom surface portion of the discharge fin member is not particularly limited. However, except for the edge portion of the bottom surface portion, the central portion of the bottom surface portion is preliminarily wrapped with masking tape or the like, And the like.

It is possible to discharge a large amount of mist to the outside without applying an unnecessarily high voltage because the electric resistance value is greatly reduced as compared with the case where the discharge fin member coated with the conductive graphite compound does not cover. Further, since oxidation reaction does not occur on the surface of the conductive graphite compound material, the discharge fin member is not clogged by the oxide, and electrostatic atomization can be stably performed without maintenance for a long period of time. The relationship between the electric resistance value and the mist generation amount will be described in detail in the following embodiments.

The mist generating member according to the present invention comprises the discharge fin member and a moisture holding member for protruding the discharge fin member upward, and the moisture holding member has a groove formed on its upper surface for coupling the discharge fin member And a conductive layer is provided on the lower surface thereof. The discharge pin member is coupled to the recessed portion so that the conductive graphite compound material of the bottom edge portion of the discharge fin member and the conductive layer formed on the bottom surface of the moisture retention member have electric conductivity.

The water retention member for protruding and forming the ejection pin member is made of a porous body or a fiber formed body formed by composing at least one kind of a ceramic material, a metal material, a synthetic resin material, and a natural resin material, And the shape is not particularly limited, but it is preferable that the shape of the whole of the electrostatic atomizing apparatus is formed into a rectangular shape having a predetermined thickness.

In addition, the water retention member may have a lower water absorption capacity and a water retention capacity than the release pin member. The water retention member sucks the aqueous solution absorbed in the water retention member to the discharge pin member without staying in the moisture retention member, .

The water retention member is provided with a recessed portion for engaging the ejection pin member on its upper surface and a conductive graphite compound material formed on the bottom surface thereof. The ejection pin member is coupled to the recessed portion, The graphite compounding material and the conductive layer formed on the lower surface of the moisture retaining member are made conductive. The conductive layer may be formed by forming the same conductive graphite compounding material as the discharge fin member on the lower surface of the moisture retaining member. Further, a separate sheet may be formed by blending a conductive material (for example, metal fiber, metal powder, etc.).

One or a plurality of recessed portions are formed, and the arrangement thereof is appropriately determined in accordance with the design of the electrostatic device such as one row or columnar shape.

The electrostatic atomizing apparatus according to the present invention includes the mist generating member and includes a reservoir portion for supplying an aqueous solution to the moisture retaining member of the mist generating member and an applying electrode for applying a voltage to the discharging fin member.

The application electrode for applying a voltage to the discharge pin member is, for example, a power source generating a DC minus voltage of about 4 to 10 kV. The cathode is connected to the conductive layer on the lower surface of the water- The holding member is negatively charged. Therefore, by connecting the moisture-retaining member and the discharge pin member with each other with electric conductivity, the negative current can be collected by the discharge pin member, and the mist having negative charge from the discharge pin member to the outside due to the natural discharge phenomenon can be released.

The water reservoir provided in the electrostatic atomizer accommodates the aqueous solution and supplies the aqueous solution to the water retention member at all times by using a capillary phenomenon or the like. The capacity and shape of the reservoir portion are not particularly limited, but may be appropriately selected depending on the mist emission amount.

As the aqueous solution to be stored in the reservoir, an aqueous solution having various functions including water is applied. Examples of the functional ingredient of the functional aqueous solution include vitamin C (L-ascorbic acid), vitamin C ester (magnesium L-ascorbic acid phosphate, sodium L-ascorbic acid phosphate, ascorbic acid phosphate), vitamin A, vitamin B, (Lavender, Rosemary, Lemongrass, Tea Tree, Sage, Clove, Orange, Grapefruit), Vitamin D, Vitamin Dα-Lipoic acid, Organic soluble components such as fructose, cinnamon and jasmine, coffee beans, refreshments, horseradish, hinokitiol, chitin, chitosan, propolis and the like. Examples of the inorganic substances (inorganic soluble components) have. Platinum nanoparticles and palladium nanoparticles can also be used.

Here, "functional" refers to a property capable of improving the living environment in a healthy way, and can be used for various purposes such as deodorization (deodorization and decomposition), antifungal biological activity (antibacterial activity, bactericidal activity, antibacterial activity, antifungal activity, Etc.), relaxation, moisturizing properties, antioxidative properties, harmful bovine repellency, antistatic properties, and dustproof properties.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

≪ Example 1 >

1 is a schematic view showing an embodiment of an electrostatic atomizer 10 according to the present invention. In the figure, the electrostatic atomizer 10 includes a reservoir 12, a water retaining member 13 for retaining the aqueous solution absorbed from the reservoir 12, a mist protruding on the top surface of the water retaining member 13, A discharge pin member 11 for discharging the discharge pin member 11 to the outside and an application electrode 15 for applying a high voltage to the discharge pin member 11. [

The ejection pin member 11 is engaged with and protruded from the recessed portion 13b formed on the upper surface of the water retention member 13.

The conductive layer 13a was laminated on the lower surface of the moisture retaining member 13 by using a nonwoven fabric impregnated with the conductive graphite by immersing the conductive graphite compound material formed around the deep portion of the ejection fin member.

As a result, the discharge pin member 11 is negatively charged and the aqueous solution 16 is sucked from the bottom face portion 11b of the discharge pin member 11 and discharged from the distal end portion 11a of the discharge pin member 11 to the negative So that the mist 17 charged to the outside is discharged to the outside.

As shown in the figure, a conductive graphite compound material 11d is formed around a deep portion 11c having a diameter of about 5 mm and a height of about 30 mm bundled with a bundle of polyethylene fibers. The conductive graphite compound material is removed from the bottom face portion 11b of the discharge pin member 11 while leaving the edge portion 11e (width of about 0.1 to 0.5 mm) (12) for forming a gap in the bottom face portion (11b) and storing the aqueous solution therein is formed when the upper face of the lower face portion (13) is protruded.

The discharge pin member 11 is coated with a conductive graphite compound material 11d around its periphery so as to surround the core portion 11c formed of a porous body or a fiber-formed body. As the conductive graphite compound material 11d, a graphite paste was produced by using conductive graphite fine particles. The graphite paste was a black viscous paste aqueous solution in which conductive graphite fine particles were dispersed with a surfactant as a protective film, and scaly graphite fine particles, EDTA (surfactant) and distilled water were mixed in a ratio of 20.0 mass%: 1.9 mass%: 78.1 mass% . The prepared graphite paste was blended with a binder-Z850 as an acrylic emulsion and a diluent as a surfactant to prepare a conductive graphite adjustment liquid. The prepared conductive graphite adjustment liquid was sprayed around the core portion 11c, dried at room temperature for about 1 hour, and then dried in a drier set at 80 캜 for 3 hours or more to obtain a discharge pin member 11.
