ケース２は、ポリカーボネートのような静電気を発生し易い材質により形成されており、基端側が閉塞された円筒形状を成すケース本体９と、ケース本体９の先端部に螺合するカバー部材１０とから構成されている。そして、カバー部材１０は、外周に形成された螺刻部１１の半分程度が露出するようにケース本体９に取り付けられ、吸気ファン４の上流側を覆うようになっている。また、ケース本体９の周壁には、電動モータ５に近接して電源スイッチ１２が取り付けられていると共に、吸気ファン４の下流側に排気口１５が設けられている。   The case 2 is formed of a material that easily generates static electricity, such as polycarbonate, and includes a case body 9 having a cylindrical shape with a proximal end closed, and a cover member 10 that is screwed into a distal end portion of the case body 9. It is configured. The cover member 10 is attached to the case body 9 so that about half of the threaded portion 11 formed on the outer periphery is exposed, and covers the upstream side of the intake fan 4. A power switch 12 is attached to the peripheral wall of the case body 9 in the vicinity of the electric motor 5, and an exhaust port 15 is provided on the downstream side of the intake fan 4.

図２及び図３に良く示されているように、吸気ファン４は、例えば、ファン口径が５ｃｍ程度で、扁平な円筒形状の外形を有しており、その周壁の所要箇所（図示では３箇所）には、ケース本体９の内面に接触可能なように、静電気発生ブラシ１３が斜め方向に取り付けられている。   As well shown in FIGS. 2 and 3, the intake fan 4 has, for example, a fan diameter of about 5 cm and has a flat cylindrical outer shape. The static electricity generating brush 13 is attached in an oblique direction so as to be able to contact the inner surface of the case main body 9.

吸気筒６は、ポリカーボネートのような静電気を発生し易い材質により、細長円筒状に形成され、本実施の形態では、例えば、その長さが５ｃｍ程度、外径が９ｍｍ程度、内径が８ｍｍ程度に設定され、その基端部はカバー部材１０に挿着されている。   The intake cylinder 6 is formed in an elongated cylindrical shape by a material that easily generates static electricity such as polycarbonate. In the present embodiment, for example, the length is about 5 cm, the outer diameter is about 9 mm, and the inner diameter is about 8 mm. The base end portion is set and attached to the cover member 10.

Then, these dusts and dirt are sucked into the intake cylinder 6 by the air flow from the front end side to the base end side generated in the intake cylinder 6 as the intake fan 4 rotates, and then are discharged from the exhaust port 15 to the outside. To be discharged.

また、この時、吸気ファン４の回転に伴い、静電気発生ブラシ１３とケース本体９の内面との間に生じる摩擦により、ケース本体９やカバー部材１０、及び吸気筒６に静電気が発生するため、前記ローパスフィルターに付着したゴミや埃だけでなく、該ローパスフィルターの周囲の微細なゴミや埃も一緒に、吸気筒６やカバー部材１０に付着させて取り除くことができる。   At this time, as the intake fan 4 rotates, static electricity is generated in the case body 9, the cover member 10, and the intake cylinder 6 due to friction generated between the static electricity generating brush 13 and the inner surface of the case body 9. Not only dust and dust adhering to the low-pass filter but also fine dust and dust around the low-pass filter can be adhered to the intake cylinder 6 and the cover member 10 and removed.

このように本実施の形態に係るローパスフィルター用掃除機１によれば、ローパスフィルターやその周辺の微細なゴミや埃をユーザ自身により簡単に取り除くことができるため、清掃作業の手間や時間を削減することができる。また、このローパスフィルター用掃除機１は、コンパクトで軽量な構造を有しているため、撮影先に常に携行することができ、さらに、片手で操作し易い円筒形状を成しているため、操作性を高めることができる。   As described above, according to the low-pass filter cleaner 1 according to the present embodiment, the user can easily remove the dust and dust around the low-pass filter and the surrounding area, thereby reducing the labor and time of the cleaning work. can do. Further, the low-pass filter cleaner 1 has a compact and lightweight structure, so it can always be carried to the photographing destination and has a cylindrical shape that is easy to operate with one hand. Can increase the sex.

なお、上記した実施の形態では、電動モータ５は電池３により駆動するようになっているが、電動モータ５にコンセント付きのケーブルを接続し、商用電源により駆動するようにすることもできる。   In the above-described embodiment, the electric motor 5 is driven by the battery 3. However, the electric motor 5 can be driven by a commercial power source by connecting a cable with an outlet.
