本発明は、紫外線光源をおおう紫外線透過性保護カバー
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an ultraviolet-transparent protective cover for covering an ultraviolet light source.
本発明は、紫外線透過性保護カバーにおいて、紫外線に
強い紫外線透過性樹脂を材料とし保護カバーを取付ける
面に対して突出した形状とすることにより、紫外線の照
射範囲を広げ照射動部をよくしたものである。The present invention is an ultraviolet-transparent protective cover that is made of an ultraviolet-transparent resin that is resistant to ultraviolet rays and has a shape that protrudes from the surface on which the protective cover is attached, thereby widening the irradiation range of ultraviolet rays and improving the irradiation moving parts. It is.

るが、上記いずれの場合も平面状に作られている。Ultraviolet light sources that emit ultraviolet light are used in various fields for sterilization purposes. For example, in ultraviolet lamps used to sterilize flour moving on a conveyor, a protective cover is attached to the ultraviolet lamp to prevent powder from adhering to the lamp and contaminating it, or conversely to prevent dust from falling from the lamp. There is. Protective covers are also provided in cleaning rooms and the like to prevent dust from being released. 7 and 8 are cross-sectional views showing conventional examples of such protective covers. In these figures, (1) is the ultraviolet lamp, (2') is the protective cover, (3) is the mounting (wall) surface of the protective cover, ((1)
indicates a protective cover attachment. FIG. 7 shows an example in which a recess for storing the ultraviolet lamp (1) is provided in the wall surface (3), and FIG. 8 shows an example in which the ultraviolet lamp (1) is housed in the fixture (4). The protective cover (2') is transparent to ultraviolet rays, but is made flat in all the above cases.
第７図の場合は、紫外線ランプ（１）から放射される紫
外線は殆ど前方を照射し、照射面積が制限される。また
、第８図の場合も、取付共（４）が紫外線不透過性であ
るから、同様に照射面積が前方に制限される。すなわち
、いずれの場合も、紫外線ランプ（１）の側方は全く照
射されず紫外線の当たらない陰（かげ）となり、照射効
率が悪い。In the case of FIG. 7, most of the ultraviolet light emitted from the ultraviolet lamp (1) irradiates the front, and the irradiation area is limited. Furthermore, in the case of FIG. 8 as well, since both the attachments (4) are opaque to ultraviolet rays, the irradiation area is similarly limited to the front. That is, in either case, the sides of the ultraviolet lamp (1) are not irradiated at all and are in the shadow where no ultraviolet rays are applied, resulting in poor irradiation efficiency.
したがって、本発明は、保護カバー付き紫外線光源の照
射面積を広げ照射効率を向上させようとするものである
。Therefore, the present invention aims to expand the irradiation area of the ultraviolet light source with a protective cover and improve the irradiation efficiency.
〔問題点を解決するための手段〕 “
本発明は、保護カバーの材料に紫外線を透過し且つ紫外
線に強い樹脂を使用し、取付は面に対して突出した形状
に形成した。[Means for Solving the Problems] “In the present invention, a resin that transmits ultraviolet rays and is resistant to ultraviolet rays is used as the material of the protective cover, and the attachment is formed in a shape that protrudes from the surface.
紫外線を透過し且つ紫外線に強い樹脂で保護カバーを作
るので、殺菌効果を上げるため強い紫外線を照射しても
、樹脂が変質してボロボロになったり変形したりするこ
とがなく、しかも、取付は面に対して突出した形状にす
るので紫外線は前方のみならず側方にも照射される。The protective cover is made of a resin that transmits ultraviolet rays and is resistant to ultraviolet rays, so even when irradiated with strong ultraviolet rays to increase the sterilization effect, the resin will not change in quality and become crumbly or deformed, and it is easy to install. Since it is shaped to protrude from the surface, ultraviolet rays are irradiated not only forward but also to the sides.

In the figure, (10) is an annular fitting with a flange on the inner circumferential edge, and (11) is a tightening ring with a tapered inner circumferential surface. In this example, we use a protective cover without a brim (2
) is held between the top of the annular fitting (10) and the tightening ring (11), and fixed by turning the screw or nut (7). Therefore, both sides of the periphery of the protective cover (2) and the outer surface of the top of the annular fitting (10) cannot be tightened by the ring (1).
It is preferable to make it slightly inclined in accordance with the taper of the inner circumferential surface in 1).

される。Although the case where the protective cover of the present invention is attached to an ultraviolet light source that is substantially stationary in a space has been described above, the present invention can also be attached to an ultraviolet light source that is movable in a space. That is, in order to sterilize the inside of a water storage tank (tank) with a lid, an ultraviolet light source can be fixed to the lid, and the protective cover of the present invention can be attached to this light source. In this case, even if the UV light source is a glass tube lamp, it is covered with a resin protective cover, so there is no need to worry about the glass scattering even if the glass tube is damaged when opening and closing the lid. Additionally, if the protective cover of the present invention is attached to the UV light source for a tank in a vehicle that is subject to shaking or shock, such as an airplane, train, or ship, glass and mercury will be prevented from falling even if the light source is damaged due to shaking or shock.

設置場所の範囲を広げることができる。According to the present invention, the irradiation area of the ultraviolet light source with a protective cover can be expanded and the irradiation efficiency can be increased. Further, since the protective cover according to the present invention is elastic, it prevents glass pieces and contents from scattering even if the light source is damaged. Therefore, the range of installation locations for the ultraviolet light source with a protective cover can be expanded.
