Title
(EN) ULTRASONIC ATOMIZATION DEVICE
(FR) DISPOSITIF D'ATOMISATION À ULTRASONS
(JA) 超音波霧化装置
Abstract
(EN)
In the present invention, an ultrasonic atomization device is provided with the following: a liquid-absorbing wick (22) that absorbs a chemical from a chemical container; and a vibrating sheet (32) that has a large number of micropores (36) that extend from one side of said vibrating sheet (32) to the other in the thickness direction thereof. The vibration of a piezoelectric vibrator (31) causes the vibrating sheet (32) to atomize and spray the chemical supplied via the liquid-absorbing wick (22). The vibrating sheet (32) has a convex section (37) that is shaped like a frustum of a circular cone, and the chemical, in which at least an organic solvent and an active ingredient are mixed, has a viscosity of 1.7-5.0 mPa∙s (20°C). This configuration increases the spray height and improves the diffusion of the sprayed liquid.
(FR)
La présente invention concerne un dispositif d'atomisation à ultrasons comprenant les éléments suivants : une mèche absorbant les liquides (22) qui absorbe un produit chimique d'un récipient de produit chimique ; et une feuille vibrante (32) qui comporte un grand nombre de micropores (36) qui s'étendent d'un côté de ladite feuille vibrante (32) à l'autre dans la direction de son épaisseur. La vibration d'un vibrateur piézoélectrique (31) provoque l'atomisation et la pulvérisation par la feuille vibrante (32) du produit chimique fourni par la mèche absorbant les liquides (22). La feuille vibrante (32) a une section convexe (37) de la forme d'un tronc de cône circulaire, et le produit chimique, dans lequel au moins un solvant organique et un principe actif sont mélangés, a une viscosité de 1,7-5,0 mPa∙s (20 °C). Cette configuration augmente la hauteur de pulvérisation et améliore la diffusion du liquide pulvérisé.

本発明は、薬液容器から薬液を吸液する吸液芯(22)と、厚さ方向に貫通した多数の微細孔(36)を有し、圧電振動子(31)の振動によって、吸液芯(22)を介して供給された薬液を霧化噴霧する振動板(32)とを備える超音波霧化装置において、振動板(32)が円錐台状の凸状部(37)を有し、少なくとも有機溶剤と有効成分とが混合された、粘度が1.7mPa・s(20℃)~5.0mPa・s(20℃)の薬液を使用するものである。当該構成により、噴霧高さが高くなり、噴霧液体の拡散性を向上させることができる。
