[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a novel pest repellent device for repelling pests, which is characterized by comprising a germicidal lamp and an optical fiber that propagates the light of the germicidal lamp. be.

[Prior Art] Conventionally, in the scenes in which we live, for example, general houses, food factories, food handling businesses, hospitals, pharmaceutical companies, offices, department stores, meeting places, hotels, trains, airplanes, and electronic devices, It is well known that the world is plagued by pest infestations such as cockroaches, mites, lice, fleas, and bed bugs. In particular, it has recently been discovered that allergic symptoms such as wheezing, atopic skin inflammation, etc. are caused by live, dead, and feces of mites. In this way, there are more pests than ever! It has become clear that this has serious negative effects on health and hygiene.

Most of these pests are exterminated using insecticides. The ingredients of insecticides are highly toxic chemicals such as organic phosphorus agents, sulfur-containing compounds, nitrogen-containing compounds, and various metal salts. Commercially available insecticides that kill pests by poisonous action, such as before eating, include spray types, coating types, adhesive types, and fumigation types. Instantly and -
It has the effect of completely killing people.

However, the daily use of large amounts of these highly toxic chemicals has caused acute and chronic toxicity problems for humans, especially infants, pregnant women, and domestic animals.
It is a major problem that harmful effects to humankind are occurring, such as the impact on general biological systems such as birds, fish, and beneficial insects, as well as large-scale environmental destruction due to the destruction of the stratospheric ozone layer by petroleum and gas, especially chlorofluorocarbon gas. It has become.

In addition, -aII germicidal lamps are used in hospitals, pharmaceutical companies, food handling establishments, etc., but these are effective only in the range where the light beam emitted from the germicidal lamp reaches, but there are many pests. The sterilizing rays cannot reach behind the living things, inside storage containers, or even deep into flooring materials such as straw mats, carpets, and tatami mats, so there is no pest repellent effect at all.

[Means for Solving the Problems] The purpose of the present invention is to solve the above-mentioned problems of the prior art. The present invention provides a novel pest repellent device characterized by comprising an optical fiber that transmits light.

The term "sterilizing lamp" used in the present invention is not particularly limited, and includes any light source that has a sterilizing effect. Specifically, it has a bactericidal effect. at least 240-400nm, preferably 245-300nm
, more preferably 250 to 260 nm, particularly preferably 253.7 nm, which is a light source having a function of generating a light beam including the entire wavelength range or a part of the wavelength range. More specifically, for example, any germicidal lamp described in the Sankyo Denki Co., Ltd. catalog "Ultraviolet Germicidal Lamp" (875-5000) may be used. Germicidal lamps include straight tube types, double wall tubes, U-shaped types, spherical types, etc., and are appropriately selected depending on the purpose of use and the amount of surplus space in the usage situation. Especially small U
Germicidal lamps of double-tube type, spherical type, and double-tube wall type are preferred;
As a straight pipe type, for example, GL4.6.8.10
．． There are 15, 20, 30, and 40, among which G
L8-30 is preferable, GLK7R2 as double tube wall
GLK8, GLD8, N5L8, N5L15GLK15
．． and H3L40, among others GLK8, N5
L15 and GLK15 are preferred, and GUL4. As spherical types, GTL2 and GGL
3.5 is preferred.

Furthermore, the term "optical fiber" refers to any type of optical fiber6.For example, there are optical fibers made of plastic and glass.Plastic optical fibers include, for example, polyvinyl chloride, polymethacrylate, polyacrylate, polystyrene, polyester, and Polyolefin-based plastic fibers are used, and among them, polymethacrylate-based fibers are preferred. Examples of polymethacrylate-based fibers include Mitsubishi Rayon Co., Ltd. catalog rEska 5IGNJ.
Any of the fibers described in [630350(K)] can be used.

Further, in order to more efficiently propagate ultraviolet rays, it is preferable to coat the outer layer of the plastic fiber with a plastic having a higher refractive index, and fluorine resin is generally preferable. Furthermore, by physically peeling off the covered plastic partially, for example, with a file, the light can be diffused in a direction perpendicular to the direction in which the light travels through the plastic fiber.

Furthermore, the term "optical fiber" as used in the present invention includes the above-mentioned fibrous materials and cloth-like materials made of these fibrous materials. Fibrous materials and cloth-like materials can be irradiated with germicidal rays emitted from germicidal lamps over a wide area in a flat manner by diffusing light in a direction perpendicular to the traveling direction of the light as described above as necessary. It can be propagated.

Here, the distance between the fibers and fibers of the cloth-like material used for the purpose of flat irradiation and propagation is as follows:
There are no particular restrictions and you can choose as appropriate depending on the usage situation.
- ultimately 1-1000 mm, preferably 5-100 m
m, more preferably 10 to 50 mm.

The thickness of the optical fiber is appropriately selected depending on the purpose and usage situation, but generally the diameter is 0.01 to 10.
mm, preferably 0.05 to 5 mm, more preferably 0.1 to 2.5 mm.

The term "pest" as used in the present invention is a general term for living things that cause various harm to us in our daily lives. , adult insects such as moths and bed bugs, as well as the eggs of these creatures, and wax.

and larvae, preferably cockroaches, mites, fleas and bedbugs, with cockroaches and mites being particularly preferred.

The "pest repellent device" according to the present invention can be used in any place where pests occur.

For example, general houses, food factories, food handling businesses, offices,
They are widely used in our daily lives, such as hospitals, pharmaceutical companies, department stores, meeting places, hotels, transportation facilities such as trains and airplanes, and electronic devices such as computers, facsimiles, telephones, and televisions. More specifically, −
If we take a house as an example, it is used in flooring materials such as slippers, carpets and tatami mats, bedding such as beds, futons, sheets and pillows, closets, sinks, storage shelves under washbasins, and cupboards. It is used in grain storage boxes, storage containers such as refrigerators and shoe cabinets, toilets, and bathrooms.
Among these, floor materials, bedding, and storage containers are preferred, and floor materials are particularly preferred.
