Description

Description: TECHNICAL FIELD The present invention relates to a vacuum cleaner capable of deodorizing dust, mites, etc., preventing insects, killing insects, or sterilizing.

(Prior Art) Some of the dust that is drawn in with the air by the vacuum cleaner is dust,
It includes various things such as dust, sand, soil, hair, food, mites and dung. These dusts provide an unsanitary environment in which bacteria propagate and mite and odors are generated. Therefore, the vacuum cleaner has been devised in various ways to prevent such an unsanitary environment.

For example, the most problematic items these days are mites and their dung lurking in carpets and duvets. As a method of killing mites, there is a method of killing them by impact by increasing the air volume of a vacuum cleaner, but it is difficult to completely kill them.

Therefore, it becomes necessary to replace the dust bag frequently. There is also a method of killing mites by heating by turning on the heating switch after completion of suction, and it is said that this method will die within 20 minutes at 50 ° C and within 5 minutes at 60 ° C.

However, this method has a drawback that a vacuum cleaner having a special structure is required.

(Problems to be Solved by the Invention) The present invention provides a vacuum cleaner capable of simply and effectively deodorizing dust, mites and the like in a vacuum cleaner, insect control, insecticidal or sterilization.

(Means and Actions for Solving the Problem) The present invention is a dust collecting bag for a vacuum cleaner that granulates a molding material composed of animal bone powder, a binder aid, and alumina, fires the granulated material, and impregnates it with chlorine dioxide. It is a vacuum cleaner placed inside.

The granular material obtained by impregnating chlorine dioxide with alkaline and porous animal bone powder is placed in the dust collecting bag of the vacuum cleaner, and the granular air reacts with the hot air containing the moisture sucked into the vacuum cleaner. It is possible to completely, simply and safely perform deodorization, insect control, insecticidal or sterilization of trash, mites and the like.

As animal bone powder, bones that have been mostly discarded in the past, such as cattle, horses, and sheep, are mainly used as animal bone meal.

Raw bones of these animals are cut into a size that can be easily burned, put into a pressure cooker, and boiled at about 200 to 400 ° C for about 90 minutes. Then, put this bone in the firing furnace, 900 ~ 1100
Approximately 60 ° C for about 60 to 180 minutes, and naturally cool in the furnace for about 60 minutes to return to room temperature or a temperature close to this. It is important to surely remove oxidative spoilage, which is a cause of oxidative rot such that gelatin, fat, protein, glue and other organic substances other than bone components remain in the bone.

By the above-mentioned boiling step, most of the organic substances attached not only to the outside but also inside the pores can be separated and removed from the bone.
Then, by passing through the above-mentioned firing step, the remaining organic substances can be completely removed, and at the same time, the humidity (water content) in the bone can be lowered to several% or less, preferably to almost 0%.

According to the above-mentioned firing conditions, the bone becomes white and maintains the original structure having numerous pores.

After firing and cooling, crush the bone and apply a powder machine
About 20 to 200 mesh, and particularly preferably 50 to 100 mesh powdery bone meal.

In the case of beef bones, the bone meal is about a weight ratio compared to raw bones.
A yield of 40% is obtained. The particles are mainly composed of calcium (about 33% by weight), phosphorus (about 16.7%) and barium (about 1.
03%), sodium (about 0.76%), sulfur (about 0.64)
%) In addition to magnesium, potassium, chlorine, amine, iron, etc., and countless micropores are continuously present inside and outside the particles. This bone meal is alkaline due to calcium and the like.

The binder aid may be any binder as long as it functions as a binder,
Examples thereof include bentonite, acid clay, activated clay, kaolin clay, sericite, pyrophyllite, refractory clay, montmorillonite, and chlorite.

It acts as a binder for alumina, and the addition of alumina increases the strength of the treated material, but if it is too large, the pores in the treated material tend to decrease.

The amount ratio of each component used in the present invention may be within the range in which the object of the present invention is achieved.

The proportion is usually 15 to 50 parts by weight, preferably 25 to 40 parts by weight of a binding aid; 8 to 25 parts by weight of alumina, preferably 13 to 20 parts by weight, based on 100 parts by weight of animal bone meal.

The molding material of the present invention can be obtained by weighing, mixing, stirring, and adding each of the above-mentioned components to a desired composition, molding into granules, and baking. An example of the blending ratio of each component is, for example, 100 parts of animal bone meal (parts by weight, the same applies hereinafter), 33 parts of tie aid, and 17 parts of alumina. The molded body is usually granular and the size is about 15 mm to 25 mm, and the drying temperature and the firing temperature are usually around 200 ° C and 800 to 1200 ° C, respectively.
Before and after.

It should be noted that a small amount of organic powder, for example, 50 to 200 mesh wood powder, rice bran, wheat dregs, chaff, waste powder, starch dregs, shochu dregs, etc. are mixed with the above components, molded and fired to form a molding material. You can also get By mixing the organic substance powder, the organic substance powder can be decomposed at the firing temperature during firing to form fine pores in the molded body, and these fine pores enable the molded body to adsorb more chlorine dioxide gas. Become.

Chlorine dioxide is usually produced by reacting sodium chlorate or calcium chlorate with an acid, but the chlorine dioxide thus obtained is extremely explosive and extremely dangerous. Care must be taken when handling. Therefore, such a chlorine dioxide gas is stabilized in an alkaline aqueous solution, and stabilized chlorine dioxide (hereinafter referred to as stabilized chlorine dioxide) has been developed. This stabilized chlorine dioxide is usually used by appropriately diluting it at the time of use, and is activated by being stimulated by an oxidizing substance in water.When activated, chlorine dioxide gas is released in water or air. The chlorine dioxide gas produced is used for sterilization, deodorization or bleaching.

Granules molded, the molded body obtained by firing, 50 ~ 150
Immerse in a chlorine dioxide solution having a concentration of 5,000 to 10,000 ppm for about 3 minutes at ℃, and let it out when chlorine dioxide is completely impregnated inside the molded body.

Moisture is removed by residual heat around 50-150 ℃, and only chlorine dioxide gas is adsorbed in the porous animal bone powder.

Several molded bodies having the chlorine dioxide gas adsorbed therein are placed in a dust bag in a vacuum cleaner, for example, an electric vacuum cleaner. Place the compact by sucking it through the suction hose of the vacuum cleaner, or by directly placing it in the dust bag, or by storing the compact in a spare dust bag beforehand and mounting it in the vacuum cleaner. Etc.

Chlorine dioxide gas is confined in the porous of animal bone powder with high alkalinity, reacts with hot air containing moisture in the vacuum cleaner and is released from the holes, effectively and reliably deodorizing dust, mites, etc. in the vacuum cleaner. It can be insect repellent, insecticidal or sterilized.

(Effect) According to the present invention, since the molded body impregnated with the stabilized chlorine dioxide solution is forcibly brought into contact with the moisture-containing air sucked in the cleaner and the hot air of dust, dust in the cleaner, There is a great advantage that deodorization, insect control, insecticidal or sterilization of mites and the like can be carried out extremely efficiently and entirely and these deodorization, insect control, insecticidal or sterilization can be carried out easily and simply.

Furthermore, its bactericidal effect is extremely remarkable, and bacteria,
Even if it contains molds and various pathogenic bacteria (Escherichia coli, Salmonella, Staphylococcus aureus, Salmonella typhi, etc.), it can be sterilized in a short time. Further, not only can the malodorous substances be destroyed, but the growth of the underlying microorganisms can be prevented, so that a double drastic effect is achieved.

Therefore, not only the smell of chemical substances such as oxygen sulfide and mercaptan, but also the putrid odor can be removed, and the stabilized chlorine dioxide is gradually released in the vacuum cleaner, which is a slow-acting and deodorant in the vacuum cleaner continuously. can do. In addition, since stabilized chlorine dioxide has no strong irritating odor and is safe, it is possible to safely perform deodorization, insect control, insecticidal or sterilization in a vacuum cleaner.

(Example) As a molding material of the present invention, 100 parts of beef bone powder, tie aid 33
And 17 parts of alumina are mixed, water is further added and further mixed, and then granulated into particles of about 10 mm and dried at about 200 ° C. Then, the dried particles are fired at around 1000 ° C. and cooled to obtain a formed body impregnated with chlorine dioxide.

Then, the above-mentioned molded body obtained by granulating and firing,
Dip it in a chlorine dioxide solution with a concentration of 5,000 to 10,000 ppm at around 100 ° C for about 3 minutes, and then put it outside.

In this way, we placed 5 forming bodies with chlorine dioxide gas adsorbed in the dust collecting bag inside the vacuum cleaner, and after actually cleaning it, we inspected the dust collecting bag stored in the vacuum cleaner. All the inhaled mites were dead and did not have the odor of using a conventional vacuum cleaner.
