However, in the conventional electrostatic atomization device, when the water supplied from the water tank is like water containing mineral components such as Ca or Mg as the tap water, the mineral component reacts with the CO ₂ in the air to absorb the water. The atomization unit precipitates and adheres CaCO ₃ or MgO, and further hinders the generation of the spray.

In order to solve this problem, an electrostatic atomization device has been described which is provided with an ion exchange portion for removing a mineral component in a water transport line, and is prevented from passing through CO ₂ with air in a pointed atomization portion. Precipitation and adhesion of CaCO ₃ or MgO generated by the reaction can be continued even without regular maintenance (for example, Patent Document 1).

Further, it is more preferable that the cover portion is not formed on the bottom surface portion.

Further, in the electrostatic atomization device of the present invention, by applying a voltage to the release pin, the moisture retained by the release pin is atomized and released into a spray.

The electrostatic atomization device includes a water storage unit, a water-containing element that retains water absorbed from the water retention unit, a release pin element that protrudes from the water-containing element and releases the spray to the outside, and an application electrode that applies a voltage to the release pin element.

Therefore, the release pin component must have high water absorption and water retention.

The release pin element is formed of a core portion composed of a porous body or a fiber molded body, and includes a conductive material and a deliquescent component to form a covering portion covering the core portion.

The porous body or the fiber molding system is formed by combining one or more of a ceramic material, a metal material, a synthetic resin material, and a natural resin material.

The core of the release pin member is such that its mesh-like voids function as a flow path for the aqueous solution.

The porous body that releases the pin element refers to a material having a large number of tiny vacancies inside, which is used as an aggregate of independent microbubbles to attract a plurality of fine pores to attract the aqueous solution. More ideal.

For example, a porous body in which ceramic particles or metal particles are sintered into a rod-like body, and a foam such as an urethane resin or a styrene resin is formed into a rod shape.

In the fiber molded body in which the pin member is released, a plurality of fibrous materials are self-melted or integrated by a part or the whole with a plurality of fibrous materials, for example, ceramic fibers (ceramic fibers ( Ceramic fiber), glass fiber, etc., organic fiber (polyester fiber, rayon fiber, nylon fiber, etc.), metal fiber (stainless steel fiber, copper fiber, titanium fiber), or the like, are formed into a rod-shaped body.

Ceramic material means a single oxide such as cerium oxide, aluminum oxide, magnesia, titania, zirconia, or mullite or zeolite. , bentonite, sepiolite, attapulgite, sillimanite, kaolin, sericite, kieselguhr, feldspar, clay (gairome) Clay), a phthalate compound (pearlite, vermiculite, sericite), or a combination of at least one of the above components, but is not limited thereto.

Examples of the metal material include stainless steel, copper, titanium, tin, platinum, gold, silver, and the like, but are not limited thereto.

Examples of the synthetic resin material include polyester, nylon or hydrazine, urethane (including polyurethane), propylene, polypropylene, and the like, but are not limited thereto. Examples of the natural resin material include pulp fibers, cotton, wool fibers, hemp fibers, and the like, but are not limited thereto.

In the fiber molding system, a plurality of hollow fibers are bundled and bundled to form a bundle.

The hollow fiber has a hollow tubular fiber inside, and is used synonymously with a very thin tube, a capillary tube, a hollow fiber or the like. 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 μm or more and 50 μm or less.

The raw materials used for hollow fibers can be processed into hollow fibers, organic materials, inorganic materials. Any of the materials may, for example, be various types of polyamido-based fibers such as nylon 6 (registered trademark), nylon 66 (registered trademark), or aromatic polyamide, and polyethylene terephthalate. Various types of polyesters such as alcohol ester (PET), polybutylene terephthalate (PBT), polylactic acid, polyglycolic acid, and polycarbonate, and acrylics such as polyacrylonitrile Various fibers such as polyolefins, polyethylene or polypropylene, various fibers of polymethacrylate such as polymethylmethacrylate, and polyvinyl alcohol. Various fibers, various fibers of polyvinylidene chloride, various fibers of polyethylene, various fibers of polyurethane, various fibers of phenol, and polydifluorocarbon Materials such as fluorine-based various fibers composed of polyvinylidene fluoride or polytetrafluoroethylene, and carbon fibers such as carbon nanotubes.

Further, in addition to the core-based porous body or the fiber-formed body, a structure having excellent water absorption and water-retaining power may be mentioned as a honeycomb structure or a wave structure, or a tubular shape, a sheet shape, or a pleated shape.

The shape of the release pin element is a rod-shaped body having a circular cross section. However, the present invention is not limited thereto, and may be an elliptical cylinder shape, a conical shape, a prismatic shape or the like. Further, the front end portion of the release pin member is more planar than a flat surface, and is preferably a curved surface shape with an arc. In the case of a sharp pointed shape, since the current does not flow to the front end portion of the release pin member, the aqueous solution cannot be sufficiently held, and therefore the tip end portion of the release pin member is preferably a shape having a moderate circular arc.

Since the water absorption characteristics of the aqueous solution differ depending on the material and structure of the core portion formed by the porous body or the fiber molded body, the release property of the porous body or the fiber molded body is determined by measuring the amount of absorption of the aqueous solution per hour. The release performance is determined by the hourly water absorption rate of the core. Regardless of the raw material, the water absorption rate is suitably about 30 to 100%. Especially for the material, the ceramic material is preferably 30 to 80%.

Examples of the deliquescent component include polyphosphate, potassium dihydrogen phosphate (KDP), citric acid, sodium hydroxide, potassium carbonate, magnesium chloride, calcium chloride (calcium). Chloride), phosphoric acid, phosphate, etc.

Phosphate can be appropriately selected from the phosphate system.

These components are deliquescent and absorb the surrounding moisture to maintain an aqueous solution in the release pin element.

Therefore, the amount of the aqueous solution from the water storage tank to be described later can be reduced or the water storage tank can be omitted.

Further, the release pin member of the present invention may not have a cover portion formed on the bottom surface portion.

Thereby, the aqueous solution can be easily absorbed from the aqueous component.

Forming a covering portion covering the periphery of the core can be formed, for example, in the following manner.

First, conductive graphite fine particles as a conductive material are mixed with a deliquescent component, a binder, a surfactant, or the like to prepare a conductivity adjusting liquid.

The binder may, for example, be a propylene latex.

The surfactant may be an anionic, nonionic or cationic surfactant.

The conductivity adjusting liquid prepared by the above method was applied around the core.

Alternatively, the core portion is immersed in the conductivity adjusting solution for about one minute.

Then, a release pin member of a conductive covering portion was formed around the core portion, and after drying at room temperature for about one hour, it was dried in a dryer set at 80 ° C for 3 hours or more.

Further, since the bottom surface portion of the release pin member of the water-containing member is protruded and the water absorption from the bottom surface portion can be easily performed, the conductive cover portion can be removed at the bottom surface portion of the release pin member.

The method of forming the covering portion on the bottom surface portion of the release pin member is not particularly limited, and it may be achieved by using a masking tape or the like to cover the bottom surface portion in advance to avoid application, and spraying a conductivity adjusting liquid or the like thereon.

The release pin member covered with a conductive material can be outwardly removed without applying an additional high voltage because the resistance value is greatly reduced as compared with the unreleased release pin member. The part releases a lot of spray.

Further, in the case where the conductive graphite is covered, no oxidation reaction occurs on the covering surface, so that the oxide does not clog the release pin member, and electrostatic atomization can be stably performed without maintenance for a long period of time.

The relationship between the resistance value and the amount of generated spray will be described in detail in the examples to be described later.

The mist generating element of the present invention is constituted by a release pin member and a water-containing member for projecting the release pin member at an upper portion.

The water-containing member is provided with a concave portion on the upper surface thereof for protrudingly providing the release pin member, and has a conductive layer on the lower surface thereof, so that the release pin member is protruded from the concave portion, and the bottom surface portion of the release pin member and the lower surface of the water-containing member are set.
