  Hereinafter, the present invention will be described in detail based on an example of an embodiment. An electrostatic atomizer 1 in the illustrated example is provided with a water tank 6 containing water to be atomized in a lower part, and is cylindrical. A holder 10 having a ventilation hole 12 on its peripheral surface, a counter electrode 3 disposed on the upper part of the holder 10, an application electrode 2 fitted in the lower part of the holder 10 to apply a voltage to water, and the application electrode The water tank 6 is composed of a plurality of rod-shaped water absorbent bodies 4 held by 2 and an ionization needle 5 which is also held by the application electrode 2, and is formed in a cup shape to constitute a water holding portion. The protrusion 60 on the outer surface of the upper end opening edge is attached by bayonet engagement with the engagement recess 29 provided in the outer peripheral flange portion 21 of the application electrode 2 mounted on the lower portion of the holder 10. Yes.

  Both the counter electrode 3 and the application electrode 2 are made of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS, and are electrically conductive. The electrode 3 is grounded through a grounding contact plate 71 that contacts the outer surface of the connecting projection 30 formed on the outer peripheral surface thereof. The applied electrode 2 which is fitted and fixed in the lower part of the holder 10 and is pressed and fixed by the rib 11 on the inner surface of the holder 10 is also high through a contact plate 72 which contacts the outer surface of the connecting projection 20 formed on the outer peripheral surface. Connected to voltage source.

  The rod-shaped water absorbing body 4 is formed of a porous ceramic and has a needle-like atomizing portion whose upper end is pointed like a needle, and a plurality of water absorbing bodies 4 in the illustrated example are applied to the application electrode 2. Is attached. These water absorbing bodies 4 are arranged at equal intervals on a concentric circle centered on an ionization needle 5 disposed in the center of the application electrode 2, the upper part projects upward from the application electrode 2, and the lower part projects downward and the water Contact with water contained in the tank 6.

  In the figure, reference numeral 22 denotes a cylindrical skirt projecting downward from the application electrode 2 and surrounds the outside of the plurality of water absorbent bodies 4, and the lower ends thereof are located below the lower ends of the water absorbent bodies 4. A lattice-shaped protective cover 17 is put on the opening. The skirt 22 in the application electrode 2 applies a high voltage to the water by making contact with the water contained in the water tank 6, and at the same time, protects the water absorbing body 4 formed of ceramic together with the lattice-shaped protective cover 17. Is to do.

  Here, when the water tank 6 is connected, the application electrode 2 substantially seals the upper surface opening of the water tank 6 so that the water in the water tank 6 does not leak even when tilted. Therefore, a slit 23 extending in the vertical direction of the skirt 22 is provided in a part of the skirt 22 in the circumferential direction, and the skirt 22 is surrounded by the slit 23 when the water tank 6 filled with water is mounted. The air in the space is evacuated to allow the inflow of water into the skirt 22.

  The counter electrode 3 mounted so as to close the upper surface opening of the holder 10 has an opening 31 in the center as shown in FIG. 3, and the edge of the opening 31 when viewed from above is the plurality of water absorptions. A plurality of arcs R having the same diameter centered on the needle-like portion at the upper end of the body 4 are smoothly connected by other arcs r. When the counter electrode 3 is grounded and a high voltage generating source is connected to the application electrode 2 and the water absorber 4 is sucking up water by capillary action, the needle-like atomization portion at the upper end of the water absorber 4 is on the side of the application electrode 2 At the same time, the arc R of the counter electrode 3 functions as a substantial electrode. Note that the opening 31 is covered with the lattice-shaped protective cover 16, thereby preventing fingers and the like from coming into contact with the ionization needle 5 and the water absorbent 4 through the opening 31.

  Now, a water tank 6 containing water is attached, and water is brought into contact with the skirt 22 of the application electrode 2. At the same time, the water absorption body 4 is sucked up by capillary action, and the counter electrode 3 is grounded and the application electrode. When a high voltage generating source is connected to 2 and a negative voltage is applied to the application electrode 2, if this voltage is a high voltage that can cause Rayleigh splitting in water, a needle-like mist on the upper end of the water absorber 4 The water that has reached the vaporizing section is subjected to electrostatic atomization that causes Rayleigh splitting and atomization of nanometer-sized particles.

  In the electrostatic atomizer 1, a negative voltage is simultaneously applied to the ionization needle 5 held by the application electrode 2, and negative ions are generated by corona discharge with the counter electrode 3. By comprising in this way, it can be set as the electrostatic atomizer provided with the negative ion generation function. Further, by providing the counter electrode 3 that is grounded and faces both the water absorbing body 4 and the ionization needle 5, the counter electrode 3 is shared by electrostatic atomization and negative ion generation. Thus, a negative ion generation function can be provided with a small number of parts. At this time, if the distance between the electrodes is the same, the voltage required for electrostatic atomization is higher than the voltage required for generating negative ions. Electrostatic atomization is more likely to occur by making the distance L2 from the ionization needle 5 to the counter electrode 3 considerably longer than the distance L1 to the counter electrode 3. Thus, if the distance between the ionization needle 5 and the counter electrode 3 is longer than the distance between the needle-like atomization portion of the water absorbent 4 and the counter electrode 3, negative ions are generated and electrostatics are generated. Since the negative voltage of the same voltage can be used for atomization, the high voltage generation circuit to be used can be shared, and the possibility of ozone generation can be eliminated. However, if the water in the water tank 6 disappears and the water held by the water absorbing body 4 is not atomized, only the negative ions are continuously generated.

  FIG. 4 shows another example. In this case, the lower end of the ionization needle 5 disposed in the center of the counter electrode 3 is extended downward to come into contact with water in the water tank 6. Although the electrical contact degree (resistance value) between the application electrode 2 and the ionization needle 5 varies for manufacturing reasons, the ionization needle 5 is added to the water in the water tank 6 to which a negative voltage is applied by the application electrode 2. Can also supply a stable negative voltage to the ionization needle 5. In the figure, reference numeral 19 denotes a handle in which both end portions are rotatably attached to the holder 10.

  5 and 6 show an air cleaner 7 provided with the electrostatic atomizer 1. A fan composed of a fan 82 driven by the motor 83 and a wind tunnel 70 is provided, and the air sucked from the suction port 76 on the front surface is filtered by the filter unit 81 and then discharged to the outside from the blowing port 77. Of the air flow path from the suction port 76 to the blowout port 77 in the air cleaner 7, the electrostatic atomizer 1 is disposed in the wind tunnel 70 of the blower and in the vicinity of the blowout port 77. ing.

  Nano-size mist, which is a mist of nanometer-size particle diameter generated by electrostatic atomization, is originally highly diffusive, but it is more diffusible because it spreads on the air blown by the blower. Therefore, the deodorizing function for the odor components in the indoor air and the deposits on the indoor wall surface due to the active species possessed by the nano-size mist can be effectively utilized. In particular, in the example shown in the figure, when the electrostatic atomizer 1 is disposed in the housing recess 73 provided in a part of the wind tunnel 70, the contact between the contact plates 71 and 72 and the connecting projections 20 and 30 is prevented. A part of the inside of the electrostatic atomizing device 1 is opened through an opening 74 (see FIG. 1) opened on the wall surface of the storage recess 73 and the ventilation hole 12 in the holder 10 of the electrostatic atomizing device 1 to make it possible. Since the wind flows in, the atomization is promoted to increase the amount of atomization, and the mist is easily scattered on the wind.

  In addition, although the electrostatic atomizer 1 is arranged in the wind tunnel 70, the air passing through the vicinity of the electrostatic atomizer 1 is clean air filtered by the filter unit 81. The sizing apparatus 1 is not soiled, and a part of the wind enters the electrostatic filtration device 1 as described above, but the electrostatic atomization hardly occurs due to the soiling.
