  The present invention has been made in view of the above-described problems of the conventional air cleaners, and an object thereof is to provide an air cleaner that is excellent in design and easily recognizes the remaining amount of the medicine.

In order to achieve the above object, the air cleaner of the present invention comprises a colorless and transparent liquid containing a deodorant and / or aromatic substance, and a granular material made of a water-absorbent resin immersed in the liquid. comprising the air purification agent, a granulate consisting of the water-absorbent resin, the same as colorless transparent granules and liquid, and a different colored granules and the liquid, it is mixed at a predetermined ratio Ri, colorless transparent granules are not visible melted into a liquid, only colored granules are visible, characterized in Rukoto.

According to the air cleaner of the present invention, a transparent colorless liquid containing a substance having a deodorant and / or aromatic, in air fresheners comprising a granulate consisting soaked absorbent resin in the liquid there, a granulate consisting of the water-absorbent resin, the same as colorless transparent granules and liquid, and a different colored granules and the liquid, from becoming mixed in a predetermined ratio, the state So the same and colorless transparent granules and liquid, and the granules were different colored liquid, mixed at a predetermined ratio, but will be dispersed, and the liquid of the granular body made of water-absorbing resin same In the state where the transparent and colorless particles are immersed in the colorless and transparent liquid, it is not visually recognized by being dissolved in the liquid. For this reason, only the colored particles different from the liquid are visually recognized in the state of floating in the liquid. Will be.
Thereby, while being excellent in design property, the air cleaner which can visually recognize the residual amount of a chemical | medical agent easily with the colored granule different from a liquid can be provided.

  Hereinafter, embodiments of the air cleaner of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the air cleaner of the present invention.
This air cleaner is an air cleaner comprising a transparent liquid 2 containing a substance having deodorizing properties and / or fragrance, and granules 1a and 1b made of a water-absorbing resin immersed in the liquid 2. Then, the granular materials 1a and 1b made of a water-absorbent resin are mixed with a transparent granular material 1a having the same color as the liquid 2 and a granular material 1b having a color different from the liquid at a predetermined ratio. .

By the way, in this state, when the air cleaner focuses on only the granular materials 1a and 1b made of a water-absorbing resin, as shown in FIG. 1A, the transparent granular material 1a having the same color as the liquid 2 and the liquid 2 are mixed and dispersed at a predetermined ratio. Actually, as shown in FIG. 1B, the granular materials 1a and 1b made of a water-absorbing resin are mixed. The transparent granular material 1a having the same color as the liquid is not visually recognized because it is immersed in the transparent liquid 2, and only the granular material 1b having a different color from the liquid 2 is not visible. It will be visually recognized in the state of floating inside.
Thereby, while being excellent in design nature, the granular material 1b of the color different from the liquid 2 can provide the air freshener which is easy to visually recognize the residual amount of the medicine.

In this case, the liquid 2, and the liquid 2 and the same color granules 1a can and this to colorless.

Further, the granular material 1b having a color different from that of the liquid 2 uses a granular material 1b colored in an arbitrary color, and is colored in three colors, for example , red, yellow, and blue. Granules 1b can be used.

The mixing ratio of the transparent granular material 1a having the same color as that of the liquid 2 and the granular material 1b having a color different from that of the liquid 2 is not particularly limited, but is in a range of about 1: 1 to 10: 1. It can be set arbitrarily.
Further, the ratio between the particles 1a and 1b made of the water absorbent resin and the liquid 2 is not particularly limited, but at least initially, the particles 1a and 1b made of the water absorbent resin are in the liquid 2. It is desirable to be in an immersed state.

  The water-absorbing resin constituting the granule 1a, 1b is a conventionally known water-absorbing resin, for example, although not particularly limited, a water-soluble resin containing starch or cellulose and hydrophilic groups such as carboxyl groups and sulfonic acid groups. Of a water-absorbent resin and a starch-acrylonitrile graft polymer obtained by polymerizing a water-soluble monomer and / or a monomer that becomes water-soluble by hydrolysis and a crosslinking agent as essential components, and performing hydrolysis if necessary. Hydrolyzate, hydrolyzate of cellulose-acrylonitrile graft polymer, cross-linked product of carboxymethyl cellulose, partial hydrolyzate of cross-linked polyacrylamide, cross-linked acrylic acid-acrylamide copolymer, cross-linked sulfonated polystyrene, vinyl ester -Saponified unsaturated carboxylic acid copolymer, crosslinked polyacrylic acid ( ), Crosslinked acrylic acid - acrylic acid ester copolymer, crosslinked isobutylene - may be mentioned maleic acid copolymer and crosslinked carboxylic acid-modified polyvinyl alcohol, self-crosslinking type polyacrylic acid salts.

The absorption ratio of the liquid (including liquid 2 containing a deodorant and / or aromatic substance) with respect to the mass of the water absorbent resin is about 10 to 1000 times, preferably 100 to 1000 times.
The water-absorbent resin preferably has a thickness of about several mm to 20 mm in a state where the liquid is absorbed and swollen.

  In addition to pigments for coloring (including fluorescent pigments and phosphorescent pigments) and dyes in the water-absorbing resin, other additives such as anti-aging agents, ultraviolet absorbers, antiseptics are used as necessary. Agents, surfactants, plasticizers, fillers and the like can be added.

The transparent liquid 2 containing a deodorant and / or aromatic substance has a conventionally known deodorant and / or aromatic substance, such as, but not limited to, a deodorant. Examples of the substance having an odor include substances extracted from plants such as rice, pine, hinoki and cocoon, acid or alkaline aqueous liquid, powdered activated carbon, etc., and substances having aromaticity include synthetic fragrances and natural fragrances. Etc.
If these are water-soluble, their aqueous solutions can be used, and if they are water-insoluble, water and an emulsifier, and if necessary, an aqueous emulsion comprising a solvent or the like can be used.

  In addition, the transparent liquid 2 containing a deodorant and / or aromatic substance includes pigments for coloring (including fluorescent pigments and phosphorescent pigments) and dyes as well as other substances as necessary. Additives such as anti-aging agents, ultraviolet absorbers, preservatives, surfactants, plasticizers, fillers and the like can be added.

  The air cleaner of the present invention has been described above based on the embodiments thereof. However, the present invention is not limited to the configurations described in the above embodiments, and the configuration is appropriately changed without departing from the spirit of the present invention. Is something that can be done.
