Description
Technical Field
The present invention relates to an indoor air purifier utilizing the antibacterial/antiviral action of copper.
Background
Copper has been known to have antibacterial/antiviral effects. The mechanism can be considered as follows: copper ions perforate the envelope of the virus, or free radicals generated by copper ions break down genetic material.
It is known by the national institute of health, research team, that the residual time for new coronaviruses is 72 hours on the surface of plastic or stainless steel, 24 hours on the surface of the carton, and 4 hours on the surface of copper.
In addition, the general corporate japanese copper center confirmed that: copper has excellent antibacterial/antiviral effects against influenza virus or norovirus in addition to bacteria such as Pseudomonas aeruginosa, escherichia coli and Legionella, cryptosporidium, and the like.
An antibacterial material utilizing such an antibacterial/antiviral action of copper has been proposed in the past, and patent document 1, for example, describes: very fine copper alloy powder having a particle size of from 1nm to 1 μm is dispersed on the surface of the article. Patent document 2 describes that: an antibacterial cloth using a composite fiber containing copper alloy wires. Patent document 3 describes that: copper powder is mixed with the antibacterial cement of Portland cement.
However, the antibacterial materials shown in these prior patent documents have the following problems, namely: copper is processed into fine powder or fine fiber in order to increase the surface area, and thus high manufacturing cost is required, and there is a problem that inexpensive products cannot be provided. In addition, there are problems in that: in a material obtained by mixing copper powder into the interior of a resin or cement, only copper powder exposed to the surface plays an antibacterial/antiviral role, and copper powder embedded into the interior of the resin or cement becomes inactive.
In addition, there is a commercially available air cleaner in which: the air in the room is sucked by a fan and is sent into the ultraviolet sterilization room, thereby reducing the activity of bacteria or viruses. However, the operation requires electric power, and moreover, strong ultraviolet rays may have adverse effects on the human body or pets, and thus, attention is required during the use thereof.

Disclosure of Invention
Accordingly, an object of the present invention is to solve the above-described conventional problems and to provide a device for: an indoor air purifier which is inexpensive to manufacture and has excellent safety without adversely affecting the human body or pets.
The present inventors focused on a large amount of chips generated when cutting copper materials by a lathe or a milling machine. These chips have been conventionally disposed of as waste. These chips are either thin and spiral or thin and thin pieces and have a large surface area, and therefore, it is conceivable that an inexpensive indoor air cleaner utilizing the antibacterial/antiviral action of copper can be provided if these chips are used.
The indoor air cleaner according to the present invention is completed based on the above-described actual burning, and is characterized in that chips generated when cutting a copper material are accommodated in a net having air permeability.
According to a preferred embodiment, the chips are spiral chips generated when a copper material is turned, and are stored in the inside of the net in a state of being compression-formed. In addition, according to another preferred embodiment, the chips are generated when milling a copper material.
The net is preferably a stainless steel net, and the net may be spherical and suspended in a room by attaching a suspension rope thereto. The net may have a container shape, and a flower shape is arranged on the upper surface of the net to produce a decoration placed in a room.
Effects of the invention
The indoor air cleaner of the present invention can be manufactured at extremely low cost because it uses chips generated when copper materials are cut by a lathe or a milling machine, which have been conventionally disposed of as waste. The chips are lightweight, have a large surface area, and are contained in a net having air permeability, whereby the chips can be prevented from scattering and air can be circulated. Therefore, bacteria or viruses floating in the air can be brought into contact with the surface of copper, and the activity thereof can be reduced.
Copper is a safe metal for the human body as it has been used in pots and tableware since ancient times, and therefore, even if an infant touches or licks the infant, it does not adversely affect the human body. In addition, the indoor air purifier of the present invention has the following advantages: since the antibacterial/antiviral effect of copper ions is utilized, the effect thereof is continued semi-permanently, and furthermore, since it is only required to be provided indoors, electric power is not required.

Detailed Description
Next, embodiment 1 of the present invention will be described. As shown in fig. 1, the chip 10 generated when cutting a copper material by a lathe is in a fine spiral shape, and the width is about 1 to 10mm and the thickness is about several μm to 10 μm, although the chip varies depending on the cutting state and the type of the copper material. Such chips 10 are lightweight and have a large surface area, and because the internal space is complicated, bacteria or viruses floating in the air can be brought into contact with the copper surface, and the activity thereof can be reduced.
The copper material used in the invention can be pure copper or copper alloy. Examples of the copper alloy include: alumina dispersion strengthened copper, silver-containing copper, beryllium-containing copper, chromium zirconium copper, cobalt-containing copper, and the like. Since these copper alloys are widely used as industrial materials, the chip 10 is produced in a large amount, and the hand can be made easily and inexpensively. The antibacterial/antiviral effect is brought about by copper ions, and an alloy component other than silver cannot be expected to have an antibacterial/antiviral effect. However, there is no case where these alloy components hinder the antibacterial/antiviral action of copper.
The spiral chip 10 generated when the copper material is turned is spiral and elastic, and is not so well processed, and therefore, as shown in fig. 2, is preferably processed into a compression molded body 11. The chip 10 can be added to the inside of the die to perform press working, whereby the working can be easily performed. Although the spherical compressed compact 11 is formed in fig. 2, the shape may be any shape such as a rectangular parallelepiped or a plate-like body. By thus compressing, the chips 10 are entangled with each other and can be plastically deformed, and a certain shape can be maintained. In addition, if the pressing pressure is excessively increased, the chips 10 are closely contacted with each other to cause a decrease in surface area, which is detrimental to air permeability, and thus, are required to be compressed to such an extent that they are not completely crushed and flattened.
As shown in fig. 3, in embodiment 1, the compression-molded body 11 is housed in a net 12. The material of the mesh 12 is not particularly limited as long as it has air permeability and strength, but in this embodiment, a stainless steel mesh having excellent durability is used. The mesh size of the mesh 12 is set to: there is no risk that the tip of the chip 10 flies out to the outside.
In embodiment 1 shown in fig. 3, a hanging rope 13 is attached to a net 12 and hung in a room. When the indoor air cleaner is hung on an air flow path such as a window side or the vicinity of a vent, bacteria or viruses floating in the air can be captured on the copper surface of the chip 10, and the activity thereof can be reduced.
Since the indoor air cleaner uses chips that have been conventionally disposed of as waste, it can be manufactured extremely inexpensively, and can obtain excellent antibacterial/antiviral effects or deodorizing effects. In addition, on the basis of safety to human body, the utility model also has: the antibacterial/antiviral effect can be continued semi-permanently.
Next, embodiment 2 of the present invention will be described.
Fig. 4 is an external perspective view showing embodiment 2, and 20 is a container formed by a net 21 having strength and air permeability. Although the material of the mesh 21 is not particularly limited, it is preferably made of metal from the viewpoint of strength or rigidity, and in the embodiment, it is: stainless steel mesh which does not rust. In the embodiment, a flat stainless steel mesh is used to form the side surfaces and the bottom surface, and a cubic container 20 having one side of 10 to 15cm is manufactured. In addition, the upper surface of the container 20 is open, and the bottom surface is not necessarily formed in a net shape. The inside of such a container 20 is filled with copper chips 22.
The chip 22 shown in fig. 4 is a chip generated when a copper material is cut by a milling machine, and is in a form of a thin plate in most cases, although it is varied depending on the cutting conditions and the type of the copper material. The chip is preferably filled in the container 20 with almost constant size, and sieved as needed. Although the chips 22 may be contained in the container 20 as they are, they may be compressed into a predetermined shape in the same manner as in embodiment 1, so that the compressed chips can be contained in the container 20 well.
The chips 22 filled in the container 20 have numerous voids with each other, and therefore, the contact area between the copper surface and the air becomes very large. Further, since the shape of the void formed in the chip 22 is complicated, bacteria and viruses floating in the air can be reliably trapped on the copper surface of the chip 22, similar to a mask. Thus, the effect of reducing the activity of bacteria or viruses floating in the air is also increased. Further, such chips 22 do not fly in the air like copper powder or copper fibers, and are not sucked by mistake. In addition, copper is a safe metal used in a pan, or the like, and therefore, even if an infant bumps or licks by mistake, it does not adversely affect the human body.
Even if the interior of the container 20 is filled with only the copper chips 22, the effect of purifying the air in the room can be exerted, but in the present invention, the decorative body 30 is disposed on the upper surface of the container 20 to produce the interior decoration. In this embodiment, a cross bar 23 is provided between the opposing sides 2 of the quadrangular container 20. The cross bar 23 is formed by bending an end 24 of a metal plate such as stainless steel downward, and has a function of preventing deformation of the container 20.
As shown in the figure, the cross bar 23 is formed with: a plurality of mounting holes 25 for inserting the decoration body 30. The position of the cross bar 23 may be the center of the container 20 as shown in fig. 4, or may be arbitrarily slid as shown in fig. 6.
In fig. 4, as the decorative body 30, a flower shape is used, and a center shaft 31 of the flower shape is inserted into the mounting hole 25 of the cross bar 23. However, as shown in fig. 5, the center shaft 31 of the flower shape may be inserted into the gap of the chip 22 from a position where the cross bar 23 is not provided. By disposing the flower shape on the upper surface of the container 20 in this manner, the appearance of a plant pot in which flowers are cultivated can be produced. However, the decorative body 30 is not necessarily limited to the flower shape, and may be appropriately changed to a figure, a national flag, or the like. The shape of the container 20 may be cylindrical, in addition to the square shape as in the above embodiment.
Although the indoor air purifier according to embodiment 2 can purify indoor air by merely placing it on a desk or the like, a small amount of water may be injected as in a plant pot as shown in fig. 7. Although the copper chip 22 does not have water absorption, a part of water adheres to the surface of the chip 22, and the rest passes through the gap of the chip 22 and flows down. Therefore, it is preferable to lay a water absorbing pad 32, or a receiving tray, on the lower portion of the container 20.
Since copper ions can exert an antibacterial effect against microorganisms in water, water in contact with the chips 22 is kept clean without producing bacteria or mold. The injected water gradually evaporates, thereby producing an effect of humidifying the room. Further, it is expected that the effect of capturing bacteria or viruses in the air when the chip 22 is in a state where water is attached to the surface thereof is more excellent than when the chip 22 is in a dry state. Thus, as with watering plant pots, it is preferable to inject a small amount of water every morning.
As described above, according to the present invention, it is possible to provide an indoor air cleaner which is inexpensive to manufacture and has excellent safety and durability of antibacterial/antiviral effects.
