In addition, the thermoelectric elements 12 arranged in multiple rows are sandwiched between the two Peltier circuit boards, and the adjacent thermoelectric elements 12 are electrically connected by the circuits on both sides, and the thermoelectric elements 12 formed via the Peltier input lead wires Is configured such that heat is transferred from one Peltier circuit board side to the other Peltier circuit board side by energization. Further, a cooling unit 6 is provided outside the Peltier circuit board on the one side, and a heat radiating unit 7 is provided outside the Peltier circuit board on the other side. In the embodiment, an example of a heat radiating fin is shown as the heat radiating portion 7.

  Moreover, in embodiment shown in FIG. 1, the rear-end part of the atomization electrode 1 is connected to the cooling part 6 of the Peltier unit 10 via the water conveyance part 13, and FIG. This is an example in which the rear end portion of the atomizing electrode 1 is connected to the cooling portion 6 of a certain Peltier unit 10.

  The atomizing electrode 1 is surrounded by a cylindrical electrode housing 14 made of an insulating material, and a ring-shaped counter electrode 9 is disposed at the tip opening of the electrode housing 14. The atomizing electrode 1 and the counter electrode 9 are opposed to each other so that the center of the ring of the ring-shaped counter electrode 9 is positioned on the extended line.

  In the embodiment of FIG. 1, by energizing the Peltier unit 10, the cooling unit 6 is cooled, moisture in the air is attached to the cooling unit 6 as condensed water W, and the condensed water W thus generated is water. It is made to supply to the front-end | tip of the atomization electrode 1 by the conveyance part 13. FIG.

  The water conveyance part 13 is comprised by the thing of capillary structures, such as a porous body and a capillary, for example, Condensation water W is conveyed to the front-end | tip of the atomization electrode 1 from the cooling part 6 side by capillary action, The water transport unit 13 is a porous body in its entire length, a full length is a capillary, or a part of the water transport unit 13 is a porous body and the other part is a capillary. Absent. Of course, the condensed water may flow down using gravity, or may be moved using external power such as a pump, or these may be combined.

  Further, the atomizing electrode 1 may be formed of a porous material such as ceramic, and the atomizing electrode 1 itself may also serve as the water transport unit 13, or the atomizing electrode 1 may be formed of a highly conductive material such as metal. The atomizing electrode 1 may be provided with a capillary structure such as a capillary.

  In the embodiment of FIG. 1, the atomizing substance supply means 3 is provided in the middle of the water conveyance part 13, and the atomization substance 20 held in the atomization substance supply means 3 is conveyed by the water conveyance part 13. The condensed water W is supplied to the tip of the atomizing electrode 1 as a solution obtained by dissolving the atomizing substance 20 in water.

  In order to supply the atomizing substance 20 from the atomizing substance supply means 3 to the condensed water W conveyed to the water conveyance unit 13, for example, a solid or gel water-soluble mist is supplied to the atomizing substance supply means 3. The water-soluble atomizing substance 20 is dissolved in the condensed water W by holding the water-soluble material 20 and bringing the water-soluble solid or gel water-soluble atomizing substance 20 into contact with the condensed water W. Note that the atomizing substance 20 held in the atomizing substance supply means 3 is not limited to being held in a solid state but may be held in a gas state.

  Since the solution supplied to the tip of the atomizing electrode 1 in this manner is obtained by dissolving the atomizing substance 20 in the condensed water W, only the target atomizing substance 20 is contained in water that does not contain impurities. Is a dissolved solution.

  As described above, the tip of the atomizing electrode 1 is applied by the high voltage applying means 4 in a state where the solution in which only the target atomizing substance 20 is dissolved in water not containing impurities is supplied to the tip of the atomizing electrode 1. When a high voltage is applied to the solution supplied to, the Coulomb force acts on the solution supplied to the tip of the atomizing electrode 1 by the high voltage, and the water level rises locally in a cone shape ( Taylor cone) is formed. When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows in this way and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the solution at the tip of the tailor cone gives large energy (repulsive force of the charge that has become dense). The charged fine particle liquid is generated in large quantities by dissolving the nanometer-sized atomizing substance 20 charged negatively or positively by repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension. The cylindrical body 23 is discharged from the front end opening.

  Moreover, in other embodiment of the electrostatic atomizer 8 shown in FIG. 2, the rear-end part of the atomization electrode 1 is connected to the cooling part 6 of the Peltier unit 10 which is the heat exchanger 5, and the Peltier unit 10 is connected. By energizing and cooling the cooling unit 6, the atomization electrode 1 is cooled, and by cooling the atomization electrode 1, moisture in the air is generated as condensed water and supplied to the atomization electrode 1. Yes.

  In the embodiment of FIG. 2, part or all of the atomizing electrode 1 is formed of the atomizing substance 20, and the portion formed of the atomizing substance 20 of the atomizing electrode 1 is the atomizing substance. The supply means 3 is comprised.

  Therefore, the atomizing substance 20 is dissolved in the dew condensation water W generated on the atomizing electrode 1, so that only the target atomizing substance 20 is dissolved in water containing no impurities. In this state, a solution in which only the target atomizing substance 20 is dissolved in water not containing impurities is supplied to the tip of the atomizing electrode 1, and the tip of the atomizing electrode 1 is applied by the high voltage applying means 4. A high voltage is applied to the supplied solution to generate a charged fine particle solution in which the nanometer-sized atomizing substance 20 is dissolved in the same manner as described above by electrostatic atomization.

  FIGS. 3 to 8 show examples in which the atomizing material supply means 3 is formed by forming part or all of the atomizing electrode 1 with an atomizing material.

  FIG. 3 shows the center of the atomizing electrode 1 whose rear end is connected to the cooling part 6 of the Peltier unit 10 that is the heat exchanger 5 as shown in FIG. 2 so that one end opens at the tip of the atomizing electrode 1. This is an example in which the atomizing substance supply means 3 is formed by providing the atomizing substance 20 in the small holes 15 formed in the axial direction. In this embodiment, the atomizing substance 20 is dissolved in the condensed water W generated on the outer surface of the atomizing electrode 1 at the tip of the atomizing electrode 1, and the atomizing substance 20 is dissolved and does not contain impurities. A solution in which only the target atomizing substance is dissolved in water is used, and this is electrostatically atomized as described above.

  FIG. 4 is a modification of the above example, in which a communication portion 16 communicating with the outer periphery of the small hole 15 and communicating with the outer surface portion of the atomizing electrode 1 is formed, and the atomization is performed in the small hole 15 and the communication portion 16. This is an example in which an atomizing material supply means 3 is formed by providing the material 20. In this embodiment, the atomizing substance 20 is dissolved in the condensed water W generated on the outer surface of the atomizing electrode 1 at a part of the outer peripheral part of the atomizing electrode 1 (the part where the communication part 16 is opened) and the tip part. Then, the atomizing substance 20 is dissolved to form a solution in which only the target atomizing substance 20 is dissolved in water containing no impurities, and this is electrostatically atomized as described above. In this embodiment, the contact area of the atomizing substance 20 to the condensed water W is widened, and the amount of dissolution can be increased.

  FIG. 5 shows still another embodiment, and the outer peripheral portion of the front end portion of the atomizing electrode 1 is connected to the cooling portion 6 of the Peltier unit 10 that is the heat exchanger 5 as shown in FIG. This is an example in which the atomizing substance supply means 3 is formed by providing the atomizing substance 20. In this embodiment, the condensed water W generated on the outer surface of the atomizing electrode 1 dissolves the atomizing substance 20 at the tip of the atomizing electrode 1, and the atomizing substance 20 dissolves and does not contain impurities. In addition, a solution in which only the target atomizing substance 20 is dissolved is electrostatically atomized as described above.

  FIG. 6 shows still another embodiment. In the outer peripheral portion of the root portion of the atomizing electrode 1 whose rear end portion is connected to the cooling portion 6 of the Peltier unit 10 that is the heat exchanger 5 as shown in FIG. This is an example in which the atomizing substance supply means 3 is formed by providing the atomizing substance 20.

  Further, FIG. 7 shows still another embodiment. As shown in FIG. 2, the fog is formed on the entire outer peripheral portion of the atomizing electrode 1 whose rear end portion is connected to the cooling portion 6 of the Peltier unit 10 that is the heat exchanger 5. This is an example in which the outer layer made of the atomizing substance 20 is provided to form the atomizing substance supply means 3. In this example, dew condensation water is generated on the outer surface of the atomization electrode 1 and at the same time, the atomization substance 20 is dissolved in the dew condensation water. Since the dissolution occurs, the contact area of the atomizing substance 20 with the condensed water W is widened, and the amount of dissolution can be increased. In this example, the atomizing substance 20 is excellent in thermal conductivity so that condensed water can be effectively generated on the outer surface of the atomizing electrode 1.

  In forming the atomizing substance supply means 3 by providing the atomizing substance 20 on a part of the atomizing electrode 1, the atomizing substance is atomized by a method such as plating, coating, or fitting. It is provided on a part of the chemical electrode 1.

  Further, as shown in FIG. 8, the entire atomizing electrode 1 may be formed of the atomizing substance 20 and the atomizing substance supply means 3 may also be used. Also in this case, the atomizing substance 20 is excellent in thermal conductivity so that condensed water can be effectively generated on the outer surface of the atomizing electrode 1.

  FIG. 9 shows another embodiment of the present invention. In the present embodiment, the atomizing substance supply means 3 is provided in the middle of the water conveyance section 13 as shown in FIG. 1 and the condensed water is conveyed from the atomization substance supply means 3 by the water conveyance section 13. The target atomizing substance 20 is supplied to W and supplied to the tip of the atomizing electrode 1 as a solution in which the atomizing substance is dissolved in water. It is provided adjacent to the heat dissipating part 7 side of the exchanger 5. In other words, the atomizing substance 20 made of solid held in the atomizing substance supply means 3 is liquefied or softened by the heat of the heat radiating part 7, thereby dissolving the condensed water W supplied by the water transport part 13. It comes to make it easier. At this time, since the atomizing substance 20 is easily mixed with the condensed water W supplied by the water conveyance unit 13 due to expansion by heat, the atomizing substance supply means 3 is provided at a position away from the water conveyance unit 13. be able to.

  Further, the concentration of the atomizing substance 20 in the solution can be changed by controlling the amount of heat from the heat radiating section 7.

  In the electrostatic atomizer 8 shown in FIG. 1 and FIG. 2, the atomizing substance supply means 3 may be detachable. FIG. 10 shows an embodiment thereof. In FIG. 10, the atomizing substance 20 is held or atomized in a part of the atomizing electrode 1 whose rear end portion is connected to the cooling unit 6 of the Peltier unit 10 which is the heat exchanger 5 as shown in FIG. The atomizing substance supply means 3 formed with the atomizing substance 20 or the atomizing substance supply means 3 that holds the atomizing substance 20 that also serves as the atomizing electrode 1 or is formed with the atomizing substance 20 can be freely attached and detached. Can be exchanged when the atomizing substance 20 is consumed, or exchanged with a different kind of atomizing substance (for example, when the atomizing substance 20 is a fragrance substance, several types of atomization are possible. It can be used according to the application by exchanging the material 20 for use).

  Although not shown, the electrostatic atomizer 8 in the embodiment of FIG. 1 can also be replaced with an atomizing substance supply means 3 so that the atomizing substance 20 can be exchanged when the atomizing substance 20 is consumed. It can be exchanged for an atomizing substance (for example, when the atomizing substance 20 is a fragrance substance, it can be used depending on the application by exchanging several kinds of atomizing substances 20). .

  The target atomizing substance 20 can be simply obtained by electrostatic atomizing a solution in which the atomizing substance 20 is dissolved in the condensed water obtained by condensing moisture in the air as in the above embodiments. It is possible to produce a nanometer-sized charged fine particle liquid that only dissolves and does not contain impurities.

  The nanometer-sized charged fine particle liquid generated in this way is very small as nanometer-size, so it not only floats over a wide area, but also on the surface of an object (for example, an object such as fiber, hair, skin). In addition to adhering, it can penetrate into the inside and exert the effect of the intended atomizing substance 20.

  The atomizing substance 20 is not particularly limited. For example, when potassium nitrate, magnesium nitrate, sodium carbonate, magnesium sulfate, or the like is used, in the case of these atomizing substances 20, replenishment of metal components to the hair or It has the effect of improving strength (preventing split ends and cut hairs) by cross-linking inside the hair such as nitrate ions, and using silver nitrate, silver sulfate, etc., can obtain sterilization action of space and objects. it can. Moreover, if it is a gaseous substance, an acidic solution will be produced | generated by bubbling a carbon dioxide, and there exists an effect, such as disinfection.

  In addition, when the atomizing substance is dissolved in the condensed water, the condensed water becomes acidic or alkaline by applying a high voltage. Therefore, the atomizing substance may be a substance that dissolves with acid or alkali.

In other words, when electrostatic atomization is performed by applying a high voltage as described above, a potential difference is generated between the surface of the atomizing electrode 1 and the discharge portion at the tip of the tailor cone, and therefore electrolysis is performed in the water forming the tailor cone. In this case, when a negative high voltage is applied to the atomizing electrode 1 (the counter electrode 9 side becomes GRD), H ⁺ increases near the surface of the atomizing electrode 1 of the tailor cone and becomes acidic. Thus, OH ⁻ increases near the tip of the tailor cone and becomes alkaline.

  Further, corona discharge is also generated by applying a high voltage, but when a negative high voltage is applied to the atomizing electrode 1, nitrate ions, nitrite ions, etc. are generated by the corona discharge, and these nitrate ions, nitrite ions are generated. And the like are dissolved in the tailor cone, and when this condition is met, the surface side of the atomizing electrode 1 of the tailor cone is also acidified by electrolysis. The surface side of the mist atomizing electrode 1 can be made synergistically acidic.

  Thus, since the surface side of the atomizing electrode 1 of the tailor cone can be made acidic by applying a negative high voltage to the atomizing electrode 1, the mist provided on the surface (tip portion) of the atomizing electrode 1 in this case When a substance that dissolves with an acid is used as the atomizing substance 20, the atomizing substance 20 is dissolved in the acid on the atomizing electrode 1 side of the tailor cone.

Conversely, when applying a positive high voltage to the atomizing electrode 1, by electrolysis OH near atomizing electrode surface of the Taylor cone ^- increase becomes alkaline is increased, in the vicinity of the tip of the Taylor cone H ⁺ It becomes acidic. In this case, since the generation of nitrate ions or the like due to corona discharge is also suppressed, the change to alkalinity on the surface side of the atomizing electrode 1 of the tailor cone due to electrolysis is preferential, and the atomizing electrode 1 of the tailor cone due to electrolysis is preferential. The surface side becomes alkaline.

  Thus, since the surface side of the atomizing electrode 1 of the tailor cone can be made alkaline by applying a positive high voltage to the atomizing electrode 1, the mist provided on the surface (tip portion) of the atomizing electrode 1 in this case When a substance that dissolves with alkali is used as the atomizing substance 20, the atomizing substance 20 is dissolved in the alkali on the atomizing electrode 1 side of the tailor cone.

  An example of the atomizing substance 20 that is dissolved by the acid includes aluminum and zinc.

  When the atomizing electrode 1 (part) is made of aluminum, a negative high voltage is applied to the atomizing electrode 1 and the atomizing electrode 1 side of the tailor cone is made acidic, so that the tailor cone dissolves the aluminum. When this is electrostatically atomized to produce charged fine particles in which aluminum is dissolved, the aluminum solution inhibits plant growth and can be used as a herbicide or the like.

  In addition, since zinc is dissolved in both acid and alkali, charged fine particles in which zinc is dissolved can be generated by applying a negative high voltage to the atomizing electrode 1 as described above. Even if a positive high voltage is applied to the chemical electrode 1, charged fine particles in which zinc is dissolved can be generated. This aqueous zinc solution acts on the skin, and can be expected to reduce wrinkles and improve skin firmness.
