  In order to cause water to be electrostatically atomized by Rayleigh splitting using such an electrostatic atomizer, water needs to be present in the needle-like atomization section. Patent Document 1 and Japanese Patent Application No. 2003-160020 describe means for transporting water to a needle-like atomization section.

It is possible to easily cause electric discharge without forming a pointed portion that is liable to occur.

  Hereinafter, the present invention will be described with reference to the accompanying drawings. First, the overall configuration of the electrostatic atomizer will be described.

  As shown in FIG. 3, the electrostatic atomizer is in contact with the liquid reservoir 1 that stores the liquid L for electrostatic atomization, the application electrode 2 that applies a voltage to the liquid L, and the liquid L. A transfer body 3 provided with an atomizing portion 5 at the tip thereof, and a counter electrode 4 facing the atomizing portion 5 of the transfer body 3. By applying a high voltage between them, the liquid L sucked up from the liquid reservoir 1 by the carrier 3 is electrostatically atomized in the atomizer 5 to generate nanometer-sized mist of charged fine particles.

  The transport body 3 has a substantially rod shape as shown in FIG. 1 and the like. The transport body 3 is transported and supplied to the atomizing section 5 provided at the tip (upper end) and below the atomizing section 5. It consists of the conveyance supply body 6. In addition, although this invention has the characteristics in the atomization part 5 of this conveyance body 3, this is explained in full detail later. The atomizing section 5 and the transport supply body 6 of the transport body 3 may be formed integrally or separate members. The transport supply body 6 transports the liquid L sucked from the lower end portion thereof to the upper end portion by capillarity and supplies the liquid L to the upper surface of the atomizing portion 5, which is desirable from the viewpoint of strength and liquid transportability. Or a porous body made of ceramic or metal or resin (plastic), or a capillary made of resin or metal having gaps or holes that cause capillary action, fibers such as felt, etc. Anything that sucks up L can be used. In the case of forming the porous body as described above, the diameter or width of the transport path 61 (see FIG. 4) for sucking up the liquid L by capillary action with particles having a particle diameter of 2 to 500 μm is formed to be 1 to 250 μm. Those are preferred. Moreover, as a metal used for the conveyance body 3, what was excellent in corrosion resistance, wear resistance, and chemical resistance such as stainless steel such as SUS304, SUS316, a titanium coated platinum, a titanium coated iron, etc. However, it is not limited to these.

  The transport body 3 is dipped in the liquid L in the tank T in which at least the lower end (usually the lower half) is the liquid reservoir 1, and transports the liquid L to the atomization section 5 at the upper end by capillary action. .

  The counter electrode 2 and the application electrode 4 are both made of a synthetic resin mixed with a conductive material such as carbon, or a metal such as stainless steel, thereby having conductivity. As shown in FIG. 1, the counter electrode 4 is formed such that an inner end edge 41 serving as an edge has a circular shape that surrounds the periphery of the carrier 3 in plan view. If the inner edge 41 has an arcuate shape, the length of the arc may be any. The counter electrode 4 is grounded, and a negative high voltage is applied to the application electrode 2 by the high voltage power source D. However, the counter electrode 4 is transported when the transport body 3 sucks up the liquid L in the liquid reservoir 1 by capillary action. The atomization part 5 provided in the upper end part of the body 3 functions as a substantial electrode. The high voltage power source D that applies a high voltage between the counter electrode 4 and the atomizing portion 5 is preferably one that can give an electric field strength of 500 V / mm or more.

  By applying a high voltage between the atomizing portion 5 of the carrier 3 and the counter electrode 4 by the high voltage power source D, the liquid L on the upper surface of the atomizing portion 5 receives a large energy due to the high voltage, and the surface tension is increased. Electrostatic atomization that causes so-called Rayleigh splitting that repeats splitting and generates mist of negative ions with nano-sized particle diameters is performed, and at this time, active species with high reactivity are generated. As the liquid L, tap water is usually used, but in addition to this, water such as ground water, electrolyzed water, pH-adjusted water, condensed water, mineral water, useful ingredients such as vitamin C and amino acids, aroma oils, and air fresheners -The liquid L etc. which contained the deodorizer etc. are assumed and are not specifically limited.

  Hereinafter, a first embodiment of the atomizing section 5 of the transport body 3 which is a main part of the present invention will be described with reference to FIG.

  As described above, the atomizing section 5 of the transport body 3 is provided at the upper end of the transport supply body 6 and may be formed integrally with the transport supply body 6 or may be a separate member. In the present embodiment shown in FIG. 2, the transport supply body 6 and the atomizing section 5 are integrally formed of a metal porous body. The atomizing portion 5 is formed in a convex curved surface shape in which the upper surface portion 51 is convex upward, and in the present embodiment shown in FIG. 1, it is formed in a hemispherical shape. Specifically, in order to cause discharge between the counter electrode 4, the inner end edge 41 of the counter electrode 4 discharging has an inner diameter of φ5 to 20 mm (preferably φ12 mm), and the inner end edge 41 and the atomizing portion 5 is preferably 2 to 10 mm (preferably 3 mm), and the diameter of the hemispherical surface 51 of the atomizing portion 5 is preferably φ1 to 5 mm (preferably φ3 mm). If the diameter of the hemispheric surface of the surface portion 51 of the atomizing portion 5 is larger than 5 mm, the electric charge does not concentrate near the top of the surface portion 51 of the atomizing portion 5, so that no discharge occurs unless a very high voltage is applied. The carrier 3 is provided with a plurality or one (one in the present embodiment shown in FIG. 1). The carrier 3 is provided with the application electrode 2 at the intermediate portion, and at the bottom, at least the lower end is a liquid reservoir. It protrudes into the liquid L of one tank T.

  The case of discharging in this embodiment will be described. Since the transport supply body 6 and the atomizing section 5 themselves are formed of a porous body, the liquid L (tap water in this embodiment) passes through the transport path 61 by a capillary phenomenon and is a hemisphere of the surface section 51 of the atomizing section 5. Then, the liquid L is transported onto the convex curved surface, and the liquid L adheres and is held over substantially the entire surface of the convex curved surface. And the liquid L moves toward the surface part 51 of the atomization part 5 toward the surface part 51 of the atomization part 5 by the electric field applied between the atomization part 5 and the conveyance supply body 6, and the atomization part 5 and the conveyance supply body The liquid L held on the surface portion 51 of the atomizing portion 5 is electrostatically atomized by causing a discharge between the six.

  At this time, by making the upper surface portion 51 of the atomizing portion 5 into a convex curved surface shape, the convexity of the surface portion 51 can be made as compared with the conventional case where discharge occurs only at the tip portion of the needle-like atomizing portion. It becomes possible to easily discharge over a wide range of curved surfaces, and a large amount of liquid L can be held on this wide range of convex curved surfaces, whereby a wide range of convex curved surfaces of the surface portion 51 of the atomizing unit 5 is obtained. Even if a discharge occurs selectively, a large amount of liquid L is held on this wide convex surface. Therefore, even if the liquid L is electrostatically atomized, the liquid L is replenished immediately. It is possible to increase the amount of electrostatic atomization per unit time. In this case, since the surface portion 51 is formed of metal, it is possible to easily cause discharge without forming the tip portion as in the conventional needle-like atomization portion (there is a tip portion rather). Metal discharge occurs, which is not preferable), and can be formed into a convex curved surface capable of discharging in a wide range and holding a large amount of liquid L as described above.

In addition, it is formed so that the outer diameter of the conveyance supply body 6 is smaller than the inner diameter of the tip member 50, and the difference may be 0.05 to 02 mm. By setting the gap between the end member 50 and the transport supply body 6 to be 0.1 mm or less, the liquid L can move through the gap by capillary action. The upper surface portion 51 of the atomizing portion 5 is formed in a convex curved surface shape (in this embodiment, a hemispherical shape as shown in FIG. 4), and through holes 52a and 52b penetrating front and back are formed in the surface portion 51.

The circular through hole 52a may be a slit-like through hole 52b having a width of 0.5 mm as shown in FIG. In addition, if the diameter of the through-hole 52a or the width of the through-hole 52b is 0.01 to 0.2 mm and the thickness of the surface portion 51 is 0.01 to 0.2 mm, the liquid L is applied by the capillary phenomenon and the electrostatic force of the electric field.

Then, the liquid L is moved toward the front side of the surface portion 51 through the through holes 52a and 52b by the electric field applied between the atomizing portion 5 and the conveyance supply body 6, and is held on the surface. And the liquid L currently hold | maintained at the said surface part 51 by the discharge between the atomization part 5 and the conveyance supply body 6 is electrostatic atomized.

  Even in the third embodiment, the upper surface portion 51 of the atomizing portion 5 is formed into a convex curved surface, so that the conventional needle is similar to the first and second embodiments. Compared with the case where discharge occurs only at the tip of the atomized portion, discharge can easily occur in a wide range of the convex surface of the surface portion 51 and a large amount of liquid L is held on this wide range of convex surface As a result, even if a discharge occurs selectively within a wide range of the convex curved surface of the surface portion 51 of the atomizing section 5, a large amount of liquid L is held on this wide convex curved surface. Even if the liquid L is electrostatically atomized, the liquid L is replenished immediately, and the amount of electrostatic atomization per unit time can be increased. And, by forming the surface portion 51 with a metal, it is possible to easily cause a discharge without forming a pointed portion as in a conventional needle-like atomizing portion, and a large amount of discharge and a large amount as described above A convex curved surface that can hold the liquid L can be formed.

  Further, as in the fourth embodiment shown in FIG. 8, the surface portion 51 of the atomizing portion 5 of the tip member 50 is a plane whose central portion is substantially orthogonal to the longitudinal direction of the transport body 3, and its periphery is It may be formed of metal so as to have a convex curved surface shape.
