2. Description of the Related Art Since history, the earth has been blessed with infinite clean air, and we have enjoyed it. However, the use of various useful resources with the rapid development of mechanical civilization, especially the thermal use of natural energy resources, has been The accelerated increase has severely polluted air and water resources, severely degraded the natural environment, and made it less than hopeful to get clean air as before. It is said that the pollutants that cause air pollution exist as positive ions, which react with and reduce the useful negative ions that are originally present in the air, and threaten the healthy growth of animals and plants and the maintenance of their longevity. It causes disease and deteriorates various structures.

[0003] In recent years, it has been noted that the incorporation of negative ions into a living body brings about health effects such as adjusting body fluid to weak alkalinity and activating metabolism. In addition, various devices for generating negative ions have been proposed because negative ions have a useful effect such as obtaining a deodorizing effect.

As a conventional negative ion generator,
Heat is applied to a metal plate such as a steel plate that generates negative ions by colliding water vapor with a special plastic wall surface and releases it into the air, or a steel plate with stone powder or the like attached to the surface. There is known a device in which negative ions are generated by colliding compressed air and released into the air.

[0005] On the other hand, there are so-called tourmaline and other so-called tourmaline-utilized stones that generate negative ion water by passing water through a tourmaline layer, and generate negative ions by adhering tourmaline powder to a futon batting. Something to make it work has been proposed.

[0006]

However, in the above-mentioned conventional negative ion air purifying apparatus, the generation efficiency of negative ions is low, and it is necessary to increase the size of the apparatus in order to obtain the desired effect. There was a problem that the equipment cost increased. In addition, using a water tank at room temperature and operating while additionally replenishing tap water and distilled water, there is a concern that microorganisms and pathogens will propagate in the water tank, and if processing air is sucked, it will have a bad effect on respiratory organs, etc. Alternatively, there is a problem that the reproduction of molds and ticks is promoted.

[0007] The conventional apparatus using tourmaline is merely for producing ionized water, and the amount of generation of negative ions is small. Therefore, there is a problem that a large amount of negative ions cannot be generated and released into the air.

The present invention has been made in view of the above-mentioned conventional problems, and has the advantage that air containing a large amount of negative ions can be easily generated, and the structure is simple and the apparatus can be provided at low cost. It is an object of the present invention to provide a negative ion air cleaning device having the same.

That is, the present invention processes air containing positive ions to efficiently generate air containing negative ions and discharges the air into a room, thereby eliminating the adverse effect on the human body due to air pollution. It is another object of the present invention to provide a negative ion air purifier capable of providing a healthy effect such as returning the physiological function of the human body to its original state.

SUMMARY OF THE INVENTION A negative ion air purifier of the present invention is characterized in that a fine powder of a substance having a function of generating OH ^- ions by causing slight electrolysis of atomized water is applied to the surface of a fibrous material. It is provided with a negative ion generating brush composed of a cylindrical body in which finely adhered fine powder adhered cloth and a large number of fiber hairs are planted, atomized moisture generating means, and a motor for rotating the negative ion generating brush.

The fine powder generates static electricity and discharges through the surrounding atomized water, thereby electrolyzing the water to generate OH ^- ions. The fine particles of water are brought into contact with the surface of such a fine powder, and a temperature difference of about 8 ° C. or more or 0.1 to 0.5 MPa (1 to
By giving a pressure difference of about 5 atm), OH ^- ions are generated and combined with surrounding water molecules, so that a large amount of negative ions can be continuously and efficiently generated. The air containing OH ^- ions may be released into the room as it is. In addition, the operation of the apparatus only requires sending the pressurized or heated atomized water toward the negative ion generating brush, and the apparatus has a simple configuration, so that the apparatus can be provided at low cost.

The above effects are caused by the temperature difference between the ground surface and the tree surface in the forest, or the temperature difference caused by the evaporation of seawater, whereby water molecules become negative ions, or the pressure or force of the waterfall hitting rocks causes water to flow. The phenomenon that molecules become negative ions is realized with a small mechanical device.

As the fine powder having a function of generating OH ^- ions, tourmaline (an tourmaline), samarskiite, haeruglinite, xenotite, modified zircon, troglomite and the like are conventionally known. Inner tourmaline (electric stone) is particularly effective.

[0014] The negative ion generating brush is obtained by covering a cylindrical body in which fiber hairs are planted in a brush shape with the above-mentioned fine powder fixed to a suitable air-permeable fibrous material. In order to fix the fine powder to the fibrous material, an ordinary technique for dyeing a fibrous structure can be used. For example, the fine powder may be dispersed in an appropriate binder solution, and the dispersion may be applied to the fiber structure by a method such as spraying or dipping. The following example is known as a suitable method.

First, the fibrous structure is surface-treated in an aqueous medium by using an alkali metal with a fixing agent containing a protein-based cationizing agent. Thereafter or simultaneously, the mineral fine powder is adsorbed to the fibrous structure by the electrostatic action of ions in the aqueous medium via the fixing agent. (JP-A-11-28306)

Alternatively, the fiber or the fibrous structure is immersed in a mixed solution of a protein-based cationizing agent and an alkali auxiliary, which is constituted by adding a protein component to the cationizing agent, to perform a cationization treatment as a pretreatment. The cationized fiber or fiber structure is immersed and heated in a mixed solution in which one or both of a dye, a fixing agent, and a color former are mixed, and dyed, and then washed with water. (JP-A-11-158785)
issue)

When the fine powder having a function of generating OH ^- ions is attached to the fibrous material in this manner, the air permeability is high and the adhesion surface area of the fine powder can be extremely increased. Negative ions are generated with efficiency.

It is said that the electrostatic voltage generated by the fine powder is inversely proportional to the square of the length of the crystal. Therefore, the smaller the particle size of the powder is, the higher the generated electrostatic voltage is.
A large effect is exhibited by setting the thickness to not more than μm, preferably about 0.1 to 1 μm.

In the atomized water generating means, a water tank containing an aqueous solution mainly composed of an aqueous medium is provided, and an ultrasonic vibrator is attached to a lower surface thereof. With such a configuration, it is possible to generate air containing appropriately atomized water with a simple device. Further, the air can be sent to the negative ion generating brush to effectively generate air containing negative ions. When distilled water is used as the aqueous medium, it is preferable that lime does not adhere to the surface of furniture or metal products and is not whitened as in the case of using tap water, but the present invention is limited to distilled water. Of course, it is also possible to carry out using ion-exchanged deionized water or tap water.

As the aqueous solution, an aqueous medium to which an antimicrobial agent obtained from essential oils extracted from various plants, such as ethyl alcohol and wood vinegar, is preferably added. As a result, it is possible to reliably prevent the propagation of microorganisms, pathogens, and the like in the aqueous solution and to scatter them in the air, and also exhibit the effect of mites repelling indoors.

In the present invention, the negative ion generating brush is disposed above the water tank. Further, by detachably mounting the negative ion generating brush, when the amount of the aqueous solution becomes low, the negative ion generating brush can be removed to easily supply water. Further, when the negative ion generating brush is damaged or its performance is deteriorated due to long-term use, it is possible to replace the brush, and it is easy to manage and maintain the apparatus.
