< Topic >Regarding to the interior, until recently, you use with manner of sort, but with job with field, increasing the insecticidal effect, it offers the whirlpool mosquito taking incense stick which can use.SolutionsTip acute angle of eddying mosquito taking incense stick 1 and that eddying the acute angle 3 to which is easy to apply the fire to also the basis destal of 2 is provided. When using with the field, in Tip acute angle you apply the fire 1 and basis destal acute angle 2, insert in the case for field and use. When you use in the interior, if the fire is applied to Tip acute angle 2 until recently in sort and the tip metallic parts of the incense stick raising are inserted in the long hole 4, it can designate use until recently as sort. Gaining acute angle even in the basis destal of the former eddying mosquito taking incense stick, making easy, to apply the fire thermal burning doing from the both ends, you can show the insecticidal effect of two times, can cancel the sharp decrease of the insecticidal effect with field work.< Choice figure >Drawing 1【課題】室内に於いては従来通りの方法で使用するが、野外での作業では、殺虫効果をあげて使用することができる渦巻蚊とり線香を提供する。【解決手段】渦巻き蚊とり線香1の先端鋭角2とその渦巻きの根元端部にも火を付けやすい鋭角3を設けている。野外での使用時は、先端鋭角1と根元端部鋭角2に火を付け、野外用ケースに入れて使用する。室内で使用する場合は、従来通りに先端鋭角2に火を付け、線香立ての先金具を長穴4に差し込めば従来通りに使用ができる。従来の渦巻き蚊とり線香の根元端部にも鋭角をもうけて火を付け易くして両端より熱焼して二倍の殺虫効果を発揮し、野外作業での殺虫効果の激減を解消できる。【選択図】図1
